The Importance of Stamping Parts for Automotive Pipe Supports

There are many kinds of automobile pipeline stamping parts, which are generally used in the transmission system and steering system of automobiles. Its advantages lie in the specification of materials, high precision and relatively low cost.

The cold stamping process technology is widely used in the production of stamping parts for automobile pipeline brackets, which is suitable for many types of stamping parts in the automobile industry and requires large-scale production. In medium and heavy-duty vehicles, most of the supporting parts, such as the frame and carriage of large vehicles, are automotive stamping parts.

The steel mainly used for cold stamping is steel plate and steel strip, which accounts for 80% of the steel consumption of the whole vehicle. The production of cold stamping materials and automobile stamping parts is very close.

Usually a relatively high-strength steel plate is selected. The quality of the selected material not only determines the performance of a good product, but also directly affects the process design of our later automotive stamping process, the service cycle of the mold and the impact of the production process. To the quality, cost, service life and production organization of the product, it is an important and complicated task to reasonably select materials that are conducive to product performance. This material is usually also designed and evaluated in the initial design, taking into account the performance and required characteristics of different types of automotive products to ensure vehicle quality and performance.

How to solve the stamping problem of electric vehicle stamping parts

The die set can be dismantled in time to check the abnormal cause of imprinting. It is verified from the consistency of the lower plane of the ejector pin and the die, and the rigidity of the lower backing plate and the lower bottom plate. It is found that the cause of the imprinting on the surface of the part is the concave The height of the mold and the push block is inconsistent. The source is that the backing plate has no hardness, and it sags after mass production, resulting in imprinting problems.

The imprint on the stamping part is caused by the protruding part of the part of the stamping die that should not be raised, and the raised part should be ground or replaced.

First of all, find the cause and location of the imprinting, and then blow the iron filings away with the blowing nozzle in the place where iron filings are likely to be generated, and check whether the mold blade is unhappy and causes too much iron filings. In addition, check it frequently during operation. , to see if there is an embossing.

The main reason for this anomaly is that the die set did not heat the die pad, and it was handed over to the responsible department for rectification. After rectification, the bottom-cutting problem solved the root cause of the imprinting problem.

How to solve the problem of unqualified stamping size of electric vehicle stamping parts

1. In the production process of electric vehicle stamping parts, due to the burrs of the stamping parts during blanking, it is necessary to study the cutting edge, and it is also necessary to pay attention to whether the blanking gap is reasonable. During bending, the instability of stamping parts is caused, mainly for U-shaped and V-shaped bending, for the guide position before bending, the guide position during the bending process, and the pressure during the bending process. Holding the material to prevent the stamping from slipping during bending is the key to solving the problem.

2. During production, the stress on the material increases, and the stamping parts tend to turn over and twist. When the material is turned over, the size of the punching hole will become smaller, and the strong pressure on the material will cause plastic deformation of the material, so the size of the punching hole will be larger. Thereby reducing the strong pressure, the punching size will be smaller.

3. In the production process of electric vehicle stamping parts, if the end is repaired with a slope or arc, due to the relief of the punching force, the stamping parts are easy to turn over and slander, so the stamping size will be larger. The convex end is flat, and the size of the punching hole is relatively small.  

What are the characteristics, design and material advantages of stamping parts?

When designing metal stamping parts, not only should the structure meet the requirements of use, but also the process requirements of the metal stamping part structure should be considered, that is, the metal stamping part structure should be adapted to the stamping process. Metal stamping parts with good structural technology can reduce or avoid stamping defects, easily ensure the quality of stamping parts, simplify the stamping process, improve productivity and reduce production costs. The main factors affecting the process performance of metal stamping parts are shape, size, precision and material.

Stamping parts are parts that can be processed by means of stamping, bending, stretching, etc. Metal stamping parts are widely used in various fields of our life, including some electronic devices, auto parts, decorative materials and so on. The structure of metal stamping parts is as follows: 

Stamping parts are mainly made of metal or non-metallic plates under the pressure of a press through a stamping die, which has the following advantages:

1. Stamping parts are stamped and manufactured under the premise of low material consumption. Its parts are lightweight and rigid. After the plastic deformation of the plate, the internal structure of the metal is improved, and the strength of the stamping part is improved.

2. The stamping parts have high dimensional accuracy, uniform size with the die, and good interchangeability. Meets general assembly and use requirements without further machining.

3. The surface quality of stamping parts is good, the appearance is smooth and beautiful, which provides convenient conditions for surface coating, electroplating, phosphating and other surface treatments.  

Large size and dimensional accuracy of automotive stamping parts

1. Large pieces and dimensional accuracy of automotive stamping parts

Automobile stamping parts are divided into many types, and the steel plates used for different types of parts are also different.

For some sealing plates, brackets and the like that do not require very high performance and the shape is not complicated, it is easy to use steel plates with general tensile properties for a long time.

Due to strict appearance requirements, large outer covering parts inevitably use specially required steel plates.

Some shapes are more complex, and some are deep shapes or steel plates with relatively sharp changes that do not require good tensile properties.

The dimensional accuracy of metal stamping parts can be generally divided into two categories: precision grade and ordinary grade. The precision grade is the precision that can be achieved by the stamping process, and the ordinary grade is the precision that can be achieved by economical means. When the machining accuracy of the mold is high, the shape and dimensional accuracy of the metal stamping parts can reach the ITl0 level, and the inner hole size can reach the IT9 level.

The surface quality of metal stamping parts should not be higher than the surface quality of raw materials, otherwise it needs to increase the follow-up processing to achieve, but also increase the cost of production.

The dimensional accuracy of metal stamping parts refers to the difference between the actual size and the basic size of the stamping parts. The smaller the difference, the higher the dimensional accuracy of the metal stamping parts. The main factors that lead to the size error of metal stamping parts are: the manufacturing accuracy of convex and concave molds, the gap between convex and concave molds, the elastic recovery of materials after stamping, inaccurate positioning, and unstable material properties.  

五金冲压件加工对弯曲件的要求有哪些?

1. The processing of metal stamping parts is a requirement for bending parts

1. The shape of the bending part should be as symmetrical as possible, and the bending radius should not be less than the minimum bending radius allowed by the material.

2. The curved side is too short and not easy to form, so the straight part of the curved side should be the curved side H>2δ. If H is required to be very short, you need to leave an appropriate margin to increase H, and after bending, cut off the added metal.3. When bending with holes, avoid hole deformation.

2. Requirements for deep drawing parts

1. The shape of metal stamping parts should be simple and symmetrical, and the depth should not be too large. In order to reduce the number of deep drawing, it is easy to form.  

2. The fillet radius of metal stamping parts does not increase the process. Otherwise, the number of deep drawing and shaping will be increased, the number of molds will be increased, waste will be easily generated, and the cost will be increased.

Whether the die used for metal stamping parts is an elastic pressure discharge plate or a fixed discharge plate depends on the size of the discharge force, and the material thickness is the main consideration. The discharge force of the elastic pressure discharge plate is greatly enhanced. Metal stamping parts are formed by applying external force to plates, strips, pipes and profiles by means of presses and dies to cause plastic deformation or separation to obtain workpieces (stamping parts) of the required shape and size.

Why does the punching size of precision stamping parts not meet the standard?

2. When the cutting edge is worn, the tensile stress of the material increases, and the stamped parts tend to flip and twist. When flipping occurs, the punch size becomes smaller. The strong pressure of the material will plastically deform the material, resulting in an increase in the size of the punched hole. When the strong pressure is reduced, the punching size becomes smaller.

3. The shape of the punch edge. If the end is repaired with a bevel or arc, due to the relief of the punching force, the punching piece is prone to turning over and smearing, so the punching size will be larger. When the punch end is flat (no bevels or arcs), the punch size is relatively small. In the specific operation practice, specific research should be carried out on specific problems, and the methods and countermeasures to solve the problems should be found out.

How to improve the automation level of metal stamping processing industry?

1. How to improve the automation level in the metal stamping processing industry

1. Mobile scrap metal

Conveyors, hydraulic dumpers and automatic feeding systems eliminate some of the most laborious manual processes in metal scrap handling.

Conveyors: Conveyors quickly and automatically remove stamping scrap and debris right from the start of production. When scrap metal and spent cutting fluid are automatically removed from core operations, forklift transfer is no longer required and production cycles are optimized.

Automatic dump truck. They receive chip carts or drums from die machining operations, then lift and flip them onto receiving hoppers. Mechanical options are equipped with advanced transfer capabilities; hydraulics facilitate low-level metal scrap transfer. Both systems are efficient for single-person trolley unloading if hand-held controls are used to guide the operation.

Loading Systems: These systems automatically transfer scrap metal into distribution containers for transport to metal recycling stations. The continuous back and forth operation of the reciprocating conveyor distributes the waste material evenly in the container. When the container is full, the level sensor alerts the operator. Loading and unloading automation can even use machine-to-machine communication to signal scrap dealers that containers are ready for pickup. Overall scales can track overall scrap production and help ensure containers are full, but also within road weight limits. These systems greatly reduce the supervision required for efficient loading.

Automatic transfer of scrap metal from one production point to another minimizes employee intervention. And, because these systems eliminate the hazards associated with manually moving scrap metal, workplace safety is improved. This can help attract and retain high-quality employees, while allocating resources for production-focused tasks in other areas of operations.

2. Modify metal scrap

Metal scrap handling equipment automates the task of reducing the turning and clumping of metal chips into flowable shovel chips. Equipment with vertical feed provides continuous positive feed operation to reduce bulk waste. Equipment with horizontal feed can accommodate a small number of narrow turns.

These systems help keep workshops free of hazardous materials and prepare scrap metal for more efficient line processing.

3. Monitor the machine

Automated machine monitoring and IIoT capabilities provide a path to success for stampers who lack adequate knowledge of facility equipment and maintenance resources as older, more experienced workers leave. Automated machine monitoring systems continuously monitor equipment performance and capture data to support predictive maintenance. Ultimately, downtime can be minimized, maintenance costs can be reduced by reducing labor overhead, productivity can be increased, and workplace safety can be improved throughout the operation.

Because IIoT communication devices collect device data and send it to the cloud, they make device data accessible to any person or device, anywhere. This can help new operators see what has caused machine failures in the past and make machine uptime more predictable. The IIoT can even send emails to suppliers to automatically order replacement parts.

4. Separation of cutting fluid

Operating after die cutting, wringers and centrifuges separate the cutting fluid from the metal chips. Especially when they are inserted into metal chip handling systems, wringers and centrifuges help to automatically remove and recycle cutting fluids, helping to speed up waste stream management. An automatic lubrication system for wringers and centrifuges with self-cleaning design and self-lubricating bearings helps support continuous operation while reducing operator-led procedures.

5. Manage cutting fluid

For stores lacking automatic fluid filtration systems, cutting fluid management requires repeated employee intervention. Operation with a flow oil separator eliminates the need to manually clean the oil in the flush tank. By automatically removing free-floating and mechanically dispersed run-oil, bacteria, mucus and inverted emulsions from individual machine oil sumps, central systems and wash tanks, run-oil separators reduce run-oil to less than 1% at a time.

A turnkey centralized fluid filtration system further improves fluid management efficiency by automatically controlling coolant concentration and continuously eliminating bacteria through ozone injection. These centralized systems require minimal operator involvement and training, making fluid management easy, seamless and easy. Cutting fluid recycling equipment can also reduce hazardous waste disposal by up to 90 percent and reduce new fluid purchases by up to 75 percent.

While automation offers a path to future resilience, it is still plagued by the stigma of the past. To take full advantage of the level of innovation that automation offers, North American manufacturing, including metal forming operations, must first dispel the misconception that automation can only eliminate jobs, when it turns out that automation can help create new jobs. An automation study by Deloitte in the UK showed that while 800,000 low-skilled jobs were eliminated, 3.5 million high-paying jobs were created.

Companies that deploy automation technology in their operations tend to grow, and those that don’t wither tend to grow. As such, automating waste streams is a way for North American stamping companies and their employees to make progress, and a way to increase operational resiliency that will allow plants to grow even in the most challenging economic conditions.
