What three aspects are included in the machining accuracy of parts?

The machining center is a CNC mechanical equipment integrating milling, boring, drilling, tapping and thread cutting, etc., and its external shape is relatively complex. The types of workpieces produced by the machining center are divided into the processing of products and molds. In the process of product parts processing, high precision and high speed are required. The neck includes the following three aspects in the processing of parts.

Machining accuracy refers to the degree of conformity between the actual size, shape and position of the surface of the machined part and the ideal geometric parameters required by the drawing.

1. Dimensional accuracy

Refers to the consistency between the actual size of the processed part and the center of the part’s dimensional tolerance zone.

2. Shape accuracy

It refers to the degree of conformity between the actual geometry of the surface of the part being machined and the ideal geometry.

3. Position accuracy

Refers to the actual positional accuracy difference between the relevant surfaces of the machined part.

The actual parameters obtained by the workpiece produced by the machining center will not be absolutely accurate. From the function of the part, as long as the machining error is within the tolerance range required by the part drawing, it is considered that the machining accuracy is guaranteed. In this process, the quality of the machine tool depends on the machining quality of the parts and the assembly quality of the machine. The machining quality of the parts includes the machining accuracy of the parts and the surface quality.

Machining accuracy refers to the degree to which the actual geometric parameters (size, shape and position) of the part after machining are consistent with the ideal geometric parameters. The difference between them is called machining error.

How long is the service life of auto parts?

As we all know, everything has a lifespan, and so do cars. As a kind of high-end consumer goods, many parts of the car are aging year by year since the date of use, which affects the overall service life of the car. Just like people, the parts of the car, like the various organs of the human body, require long-term maintenance and maintenance. So, how long is the service life of each part of the car? Below, the editor of Zhejiang Balford Electromechanical will take you to find out!

1. Engine

As the “heart” of a car, the engine plays an important role. Generally speaking, the engine life of a car is about 10 to 15 years. Under the premise of paying attention to daily maintenance, the car engine is not easy to be damaged and scrapped. Therefore, drivers should pay attention to maintaining good driving habits when driving at ordinary times to avoid abnormal operation of the engine. With the continuous advancement of science and technology, technology and materials are more refined and practical than before, and the service life of the engine has been extended. If the owner maintains the car every day, it will not be a problem for a long time.

2. Brake pads

In addition to handbrake braking, most car braking systems rely on foot brakes, and the brake pads include front and rear brake pads. The wear and tear of brake pads is closely related to normal car braking. If the brake pads are damaged or abnormal, their working state will directly affect the normal driving of the driver. Since the front part of the car generally weighs more than the rear part, the force acts to move forward during emergency braking, so the loss of the front brake pads is generally greater than that of the rear brake pads. Under normal circumstances, the mileage of the front brake pads is about 40,000 kilometers, and the rear brake pads are about 80,000 kilometers, forming a significant difference.

3. Seat belt

Seat belts are the direct "life rope" for passengers, and it is the most commonly used and most overlooked auto accessory. The average lifespan of a car seat belt is not high, about three years. With time and frequent use, its protective effect will become weaker and weaker, especially after the service life. With the passage of time, the seat belt cannot firmly grasp the occupants in the car, and there will be problems such as falling off, slipping, or even the lock is not firm. It cannot protect personal safety at a critical moment, affecting normal safe travel, and the consequences are serious.

4. Airbags

Like the seat belt mentioned above, the car airbag is a protective measure for the safety of the occupants in the car. They can protect us in critical moments of imminent danger. Seat belts control our body to fly out of the car from strong impact, and airbags can reduce the impact of impact on the body, both play an absolutely important role in protection. The service life of the airbag is generally about 10 years, but it is set up to prevent sudden danger, so it cannot be used in most cases.

In daily life, some vehicles cannot work smoothly due to their long service life and the airbags exceed their service life, and cannot handle emergency situations, causing serious losses. Most car owners are reminded not to forget to check the airbags regularly. Now the automotive market has also developed vehicles with multiple airbag configurations in response to this problem, which has won a lot of praise. Friends who have the intention to buy a car but have not yet bought a car also suggest paying more attention to the number of airbags when choosing a new car to improve travel safety.

The above four are actually directly related parts of the life of the car and the people in the car. Their presence ensures the safety of life and can play a rescue role at a critical moment. They need to be taken seriously in our daily lives, with frequent inspections and maintenance. As the old saying goes “the body is the capital of the revolution”, the car also has life, and the parts are in good condition, so that the car can be “healthy”!

What is the reason for the cracking of stamping parts?

1. Reasons for bending and cracking of stamping parts

1. The steel used has poor plasticity, including the low elongation of the steel, the uneven grain size, the continuous occurrence of harmful Widmanstler structures, the cold bending performance that does not meet the technical standards, and the poor surface quality of various kinds, etc. Problems may cause a drop in plasticity, resulting in the consequences of bending cracking.

2. When the angle between the bending line and the direction of the embossing of the sheet does not meet the layout regulations, the angle between the direction of the embossing of the bent sheet does not meet the process regulations.

3. The bending radius is too small, and the deformation degree of the outer metal during the bending process exceeds the deformation limit.

4. The quality of blank shearing and punching sections is poor, such as large burrs or cracks in the sheet at the bend.

5. The thickness of the material is seriously out of tolerance, which will cause difficulty in feeding and cracking.

6. Factors such as the wear of the mold fillet radius or the too small gap, the rough surface of the die or the improper design structure cause the feeding resistance to be large, and the stamping parts are easy to crack.

7. The quality of pickling is poor, and the pickling process of steel is carried out carelessly, resulting in over-pickling or hydrogen embrittlement, resulting in reduced plasticity and cracking.

8. Insufficient lubrication, high friction, easy to cause cracks.

Second, the solution to the bending and cracking of stamping parts

1. Improve the condition of the steel plate, mainly including the selection of steel with good plasticity (such as good cold bending performance), local annealing in the parts with large deformation, and improving the quality of the sheared blank section.

2. Improve the technical state of the working part of the mold, reduce the roughness of the working surface of the convex and concave mold, and adjust the reasonable gap.

3. Formulate the correct process plan, select the appropriate process plan, so that the flow resistance of the steel during the bending process is small and the deformation is easy.

4. Improve the manufacturability of the product structure, select a reasonable fillet radius, and increase the process incision at the local bending part to avoid root fracture.

5. Improve lubricating conditions, lubricate rationally, and use lubricating oil with good lubricating performance to reduce the resistance of steel flowing during the bending process.

How to process precision mechanical parts to meet the precision requirements?

Enterprise personnel engaged in precision machining know that in order to process a reasonable precision hardware, in addition to purchasing precision processing equipment, precision testing instruments are also essential, including three-dimensional, altimeter, hardness tester, micrometer, etc.

Three-dimensional measuring instrument: It is mainly an instrument for measuring precision mechanical parts by taking three-dimensional points. The three-dimensional is also commonly known as the three-dimensional coordinate. The reason is that the measured workpiece is placed in the three-dimensional measurement space, and the coordinate position of each measuring point on the measured object can be obtained. The measurement personnel can calculate the spatial coordinate value of these points. The geometric size, shape and position of the measured object.

The three-dimensional measurement principle is stated above, so which positions can it be used for? It can measure the size of spherical shape, cylindrical shape, conical shape, etc., and can also measure the curve. After software analysis, the size is digitized, displayed in numbers, and then the computer is used for geometric processing, which can be beneficial to better. Control the precision of machining precision mechanical parts.

Altimeter: An instrument used to measure the height of a spatial point relative to the ground. It can measure the height, depth, groove width, inner and outer diameter, hole center distance, shaft center distance, flatness, verticality, etc. of precision mechanical parts. When measuring, the height gauge and the scribing claw should be matched reasonably so that the line drawn on the workpiece is parallel to the platform, and the height gauge should be matched with the lever dial indicator, which can reduce the measurement error.

Hardness tester: Literally, it is a test instrument for measuring the hardness of a material, indicating the ability of a material to resist the pressing of a hard object into its surface. High hardness also indicates good wear resistance.

Finally, the precision machining manufacturer Shilihe Electromechanical Equipment Co., Ltd. reminds you: the three-dimensional, altimeter, these precision instruments have certain requirements for the ambient temperature and humidity, the best working environment: temperature (20±2) ℃, The humidity is 55%-65%, the purpose is to ensure the accuracy of the data.

Why do you need to spray the protective punching mesh?

The principle of punching molding spray technology is that when the plastic powder is charged by a high-voltage electrostatic device, and under the action of an electric field, the paint is sprayed on the surface of the punching mesh, and the powder will be uniformly adsorbed on the surface of the punching mesh to form a powdery coating.

The powder coating is leveled and solidified after being baked at high temperature, and the plastic particles will melt into a dense final protective coating with various effects; it is firmly attached to the surface of the perforated mesh.

Electrostatic powder spraying is used for punching forming mesh spraying, and powder spraying uses electrostatic generators to make plastic powder charged with electricity. Adsorbed on the surface of the iron plate, baked at 180°C to 220°C, and the powder is melted and attached to the metal surface.

The punching and forming mesh is sprayed with plastic, which has no pollution to the environment and no harm to the human body. The characteristics of spray plastic are bright appearance, higher strength and mechanical strength, and higher corrosion resistance and wear resistance. The colors of spraying are white, blue, green, silver, yellow, etc.

How to adjust the production of precision metal stamping parts?

1. The adjustment method is: first turn the material thickness adjustment disk clockwise, and pull the material belt with one hand. If the material tape can be pulled out, it needs to be slowly turned counterclockwise until the material cannot be pulled out, then turn the two small grids counterclockwise, and then tighten the screw. If the material cannot be pulled, but the clockwise or counterclockwise rotation of the material thickness adjustment dial is relatively loose, use your fingers to slowly and gently turn clockwise, but do not use force. Turn the two small grids counterclockwise until they can’t turn, and then tighten the screws. The same goes for the adjustment of the retaining clips.
2. After adjusting the material thickness of the moving splint, the flywheel of the punch press needs to be rotated 90 degrees clockwise. During this period, it is necessary to check whether the moving splint is in a clamped state. Adjust the material thickness of the retaining clip by 90 degrees. First turn on the main switch for clamping and loosening the feeding clip, place 1.5T material at the material thickness adjustment plate of the moving clip, hold up the moving clip material block without clamping the material, then pass the material through the fixed clip, and then clamp the feeding clip Tighten the main switch and turn it off, and then adjust the thickness of the fixed clip material according to the method of adjusting the thickness of the moving clip material.

3. After the distance is adjusted, turn on the main switch for clamping and releasing the feeding clip, remove the material placed on the material thickness adjustment plate of the moving clip, and move the flywheel of the punch press away from the upper mold stripping plate to guide the needle into the lower mold to float. When the pin hole is 2/3, adjust the feeding machine relaxation time.

4. When the straight section of the guide needle is about to leave the material belt when the punch is shaken through 180°, it is necessary to check whether the fixing clip is clamped at this time.

How to cut sheet metal parts?

The cutting process in sheet metal parts processing can not only change the style, but also deal with aspects such as thickness, so the effect of using it in different environments is also different. Therefore, cutting is the function of sheet metal parts changing their essence during processing, and we must know quite a few cutting methods.

Electric welding, plasma cutting, laser cutting and other methods are more common, and laser cutting is used in the sheet metal processing process. This is because the hardness of sheet metal is relatively hard, so choosing laser cutting is also a better choice when processing.

When using laser cutting, the section is relatively neat and clean. It will be simpler to dispose of in the later stage, and it will be more suitable when used. When using it, there will be no inconsistency in the environment, and the effect that can be exerted is quite large. Be very careful when cutting to avoid confusion on the cut side.

Why do automotive metal stamping parts cause tearing?

Why do automotive metal stampings cause tearing? The quality of stamped products will lay a solid foundation for the appearance and performance of the vehicle. Therefore, the quality assurance of stamping parts has always been a problem that automobile manufacturers attach great importance to. In this article, the editor of Zhejiang Baifudu Electromechanical shares the reasons for the tearing of automotive metal stamping parts.

The stamping process of common tearing and skewing of metal stamping parts is: blanking punching – punching incision – flanging forming – incision – flanging. There are many forms of tearing and skewing of the intermediate protective bracket during the forming process. The tearing parts are mainly distributed in the hole shape of the part, the junction of the R arc and the wall neck at the corner of the side wall, etc. Different, the proportion of each fracture site is different. The tear can be a one-time forming tear or a tear caused by a fatigue crack, i.e. invisible crack development.Analysis of the reasons, according to the actual situation on site, by checking the tearing position, fracture shape and crushing degree of the parts, it is believed that the tearing and skewing behavior of the parts is mainly reflected in the flanging forming process, and the reasons for this process phenomenon are as follows:

The molding process parameters were not implemented correctly. In the forming process of the part, the process requires that the die, the pressing material core and the parts of the two must be closely attached together, and the forming is realized by the plastic deformation of the pressing plate when the machine tool slides down. However, due to the unstable quality of the pressed parts, it means that the pressure of the machine tool is in a state of unbalanced pressing during the production process. The main reason is that the processing technicians did not adjust the machine tool pressure in time according to the requirements of the process regulations at this stage, or did not communicate with each other about the stability of the machine tool pressure during the handover process. Every shift changes, resulting in poor and unstable parts quality.

The common design defects of flanging forming molds for left/right parts with one mold and two cavities, in addition to flanging, also have shape forming content, and the finished parts are particularly complex, the bending surface is narrow, and the forming requirements of the concave mold core are consistent with the forming surface, resulting in The mold structure has a large forming stroke and a small pressing area. In the initial mold design, the designer only considered the small feature of the pressing surface, while ignoring the guiding sliding of the pressing core forming

to make.

What should be paid attention to in the production process of stamping parts?

n the production and processing of stamping parts, there are many problems that need to be paid attention to. In this article, the editor of Zhejiang Baifudu Electromechanical summarizes the six points that should be paid attention to in the production of stamping parts. Let’s take a look together!

1. Regularly check the punch turntable and the die mounting base of the stamping parts to ensure the coaxial accuracy of the upper and lower turntables.

2. Before installation and use of metal stamping parts, strict inspection should be performed to remove dirt, and carefully check whether the guide sleeve and die lubrication of deep drawing parts are good.

3. In order to ensure the service life of the stamping parts, the spring of the mold should be replaced regularly to prevent the fatigue damage of the spring from affecting the use of the stamping parts.

4. When the mold is installed, the stamping personnel should use soft metal to manufacture operating tools to prevent damage to the stamping parts caused by knocking and crushing during the installation process.

5. When the punch and die edges of the stamping parts are worn, they should be stopped in time and sharpened in time, otherwise the wear degree of the die edges will be rapidly expanded, the die wear will be accelerated, and the quality of the stamping parts and the life of the die will be reduced.

6. According to the die installation procedure, install the convex and concave die on the turntable to ensure that the direction of the convex and concave deep drawing stamping parts is consistent, especially the stamping parts with directional requirements should be carefully installed to prevent wrong installation and flipping.

Well, the above is about “six points to pay attention to in stamping parts processing”, I hope the above content can help you.
