What Is Deep-Drawing Stamping

Deep drawing is a metal stamping process, which is used to make metal sheets into various hollow axisymmetric parts. This form of metal stamping includes applying a punching force to the metal plate to pull it radially into the die cavity. First, sheet metal is placed on the forming die. The plate is fixed at the end by the pressure applied by the edge retainer. Then use the mechanical stamping tool to apply axial force to the metal plate to deform the workpiece and flow into the mold cavity to produce the desired shape. Almost all manufacturing industries are likely to benefit from the deep drawing manufacturing process. This technology may be most suitable for manufacturing small stamping parts, such as electronic caps, housings, and assembled housings. However, products of various shapes and sizes can be economically manufactured through this process, including items such as aluminum cans, cookware, and kitchen sinks. In mass production, deep drawing is particularly beneficial, because as the number of units increases, unit costs are significantly reduced: once the tools and molds are created, the process can continue with almost no downtime or maintenance costs.

Characteristics of metal stamping parts

Metal stamping parts are widely used in life and are one of the most common metal products. Stamping parts have many characteristics. Stamping plants need to understand the characteristics of stamping parts in order to achieve better production. . Zhejiang Balford Precision Stamping – Over the past 20 years, we have been committed to the customized processing of precision stamping parts and accumulated rich experience. Next, Balford precision stamping will introduce the main features of stamping parts.

1. The materials for the production and processing of metal stamping parts mainly include cold rolled, hot rolled, stainless steel plate, copper and other metal strips.
2. The advantage of stamping parts is that they are made by stamping on the premise of low material consumption. . Stamping parts are light in weight and have good toughness. After plastic deformation of raw materials, the structure of metal components is improved, gradually increasing the compressive strength of the stamping parts produced.
3. In the whole production process of stamping parts, since the surface of the material will not be damaged, it has good surface quality, and the appearance is smooth and beautiful, which provides convenience for surface treatment such as surface spraying, electroplating process, air oxidation, etc.
4. Stamping parts have high specification accuracy. Stamping parts produced by the same die have uniform size and good interchangeability. General installation and application requirements can be met without further processing

Continuous die stamping

Continuous die stamping is characterized by high batch production efficiency, easy automation, safe operation, long die life, reduction of equipment, die number and workshop area. . Now stamping parts manufacturers generally change from single punch to continuous die stamping. Today, we will give a brief introduction. Continuous die, also known as progressive die, refers to the punching die that can complete multiple processes at several different positions simultaneously in one stroke of the press. . That is, the processes of trimming, cutting, grooving, punching, plastic deformation and blanking can be completed in a pair of moulds. According to the actual needs of stamping parts, the manufacturer of stamping parts shall arrange multiple stamping processes in a certain order for continuous stamping. This also provides favorable conditions for high-speed automatic stamping.

The output and batch size of the processed parts must be large enough, otherwise it is not conducive to cost control. . The mechanical properties of stamping materials need to be relatively stable, and there are also high requirements for width and thickness tolerances and straightness of material edges. The press used shall have sufficient strength, stiffness, power, accuracy, large working surface and reliable braking system.

The main focus/point of the continuous die stamping process is strip steel, as strip steel is the core/core of the entire continuous die stamping process. Bar chart design involves the designer’s design ideas. It is necessary to know how many parts the strip steel consists of, such as material points, cutting positions, bending process, etc.

Metal Spring Clip

Metal spring clips are usually made of stainless steel or manganese alloy after heat treatment and are important parts of electronic switches. The spring clamp plays an important role in the high-quality switch between the operator and the product. At the same time, stable toughness and long life performance will provide good tactile feedback for the operator.

Material Science

Generally, copper, carbon steel, stainless steel, manganese and other materials are used to manufacture metal spring clips. Factors such as heat resistance, quenching, corrosion resistance, fatigue strength and elastic limit should be considered comprehensively.

features

Metal spring clip is mainly used to control the movement of machinery, store and output energy, absorb vibration and impact energy, and is also a force measuring element.

application

Metal spring clips have been widely used in various fields, especially in the mechanical and electrical industry, mainly in electronics, electrical appliances, advertising, IT, communications, automobiles, buildings, furniture, bags, craft gifts, sports equipment, clothing, outdoor, etc.

What Is a Stamping Die?

Stamping is a cold forming operation, which means that no heat is intentionally introduced into the die or sheet. However, due to the heat generated by friction during cutting and forming, stamping parts are usually very hot when leaving the mold.

Mold sizes range from mould (palm size) used to make microelectronic products to mould 20 square feet and 10 feet thick used to make the entire car body sides.

Parts produced by the stamping process are called parts. Some molds can produce more than one part in a cycle, and the cycle speed can reach 1500 cycles. 40. Stroke&# 41. Every minute. Pressure causes death.

What is Deep Drawing Stamping?

Drawing and stamping is a manufacturing process that uses dies to stretch materials into final shapes by pressing metal sheets into dies. The main benefit is that it can create complex shapes quickly and efficiently. If you need metal parts with a lot of curves or complex details, this stamping may be an ideal choice. Because it can adapt to almost any design limitation, and deep drawing parts are more durable than stamping parts, because they will be slightly worn in the production process.

Characteristics of stainless steel in sheet metal processing

　As a supplier of Stamping dies, let us share with you the technical characteristics of stainless steel in sheet metal processing.

Due to the high yield point and high hardness of stainless steel, the effect of cold work hardening is remarkable. The characteristics of the stainless steel sheet when drawing are as follows:

1Because thermal conductivity is worse than ordinary low carbon steel, the required deformation force is large;

2(3) The rebound is caused by the bending and reverse bending of the sheet at the corner of the deep drawing die, usually forming a concave deformation on the sidewall of the Sheet Metal Bending Parts, so that the product with higher dimensional accuracy and shape requirements needs to increase the shaping process.

different types of Auto Stamping Parts

Auto Stamping Parts, as the name suggests, are metal stampings that make up automotive parts. In automotive stamping parts, some of them are directly transformed into auto parts after being stamped, and the other part is subjected to welding, machining, or painting after being stamped to become auto parts. There are many kinds of automobile stamping parts, such as automobile shock absorber stamping spring tray, spring seat, spring bracket, end cover, cover, compression valve cover, compression valve sleeve, oil seal seat, bottom cover, dust cover, impeller, oil cartridges, lugs, brackets, etc. These are all automotive stampings.　In Auto Stamping Parts China, stamping is sometimes referred to as sheet forming, but with a slight difference. The term “sheet forming” refers to the use of sheet material, a thin-walled tube, a thin profile, or the like as raw material. The method of forming plastic work is collectively referred to as sheet forming, and at this time, deformation in the direction of the thick plate is generally not considered.

First, the application range of metal stamping parts:

1. Special stamping enterprises. Such as the stamping of aviation parts, etc. belong to such enterprises, but these craft factories are also owned by some large factories.

2. Stamping of parts and components in the automotive industry. Mainly punching and forming. Many of the companies in this sector belong to scale factories, and there are also some independent stamping plants. At present, there are many such small factories near some automobile factories or tractor factories.

3The stamping factory of daily necessities. Do some crafts, tableware, etc. These factories have also grown significantly in recent years.

4. Stamping in the automotive industry. Mainly drawing. In this part of China, we mainly focus on large factories such as automobile factories, tractor factories, and aircraft manufacturers. Independent large scale stamping and deep drawing plants have not been seen.

5. Electric stamping plant. This type of factory is a new industry that has developed along with the development of electrical appliances, which are mainly concentrated in the south.

6. Household appliance parts stamping plant. These factories only emerged after the development of household appliances in China, and most of them are distributed to household appliances enterprises.

Second, the detection of metal stamping parts:

The hardness of metal stamping parts is measured by a Rockwell hardness tester. Small, complex-shaped stampings can be used to test small planes that cannot be tested on ordinary Rockwell benchtop hardness testers. Stamping parts processing includes punching, bending, drawing, forming, finishing and other processes. The materials processed by stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal strip materials, such as carbon steel sheets, alloy steel sheets, spring steel sheets, galvanized sheets, tin-plated sheets, stainless steel sheets, copper and copper alloys. Plate, aluminum and aluminum alloy plates, etc.

Rockwell’s PHP series of portable surface hardness testers are ideal for testing the hardness of these stamped parts. Alloy stampings are commonly used in metal processing and mechanical manufacturing. Stamping is a process that uses a Stamping Mould to separate or form a metal strip. Its application range is very broad.

Sheet Metal Fabrication

Technical aspects: During Sheet Metal Fabrication, in order to achieve the purpose of reducing investment, workers are required to strictly follow the consumption standards to complete the work process. Before each processing, the application must stop reviewing the application status of the data. Ability to stop processing at will. Many of the processing industry’s costs are due to the lack of good data before processing, so staff must first understand the types of processing data, check data specifications and models, and make good preparations to prevent errors during processing. It can also reduce the amount of waste, and workers should pay attention to these issues during processing.

To measure the quality of a sheet metal processing plant, first, look at the incomplete equipment; second, look at the skills of its operators; third, look at the order of the processes.

First, TOX riveting

The connected piece is pressed into the female die through a simple male die. Under further pressure, the data in the die is “moved” outward. The result is a round joint with no sharp edges and no burrs, and it will not affect its corrosion resistance. Even externally plated or spray painted plates can also retain the original rust and corrosion resistance characteristics. The paint layer also deforms with it. The material is squeezed to both ends, into the plate on the side of the die, and then forms a TOX connection point.

Rivet riveting

This type of rivet is often called rivet, and riveting two plates together is called rivet.

Third, hole riveting

One part in the middle is a drawing hole, and the other part is a counterbore. After being riveted, it becomes an inseparable joint. Superiority: The sinkhole with which the hole is matched has the positioning function itself. The riveting strength is high, and the riveting efficiency through the mold is also higher.

Electronic Stampings Parts

The surface and intrinsic properties of electronic stamping materials have a great influence on the quality of stamped products. The thickness of stamping material is required to be precise and uniform; the surface is smooth, no spots, no flaws, no scratches, no surface cracks, etc.; Uniform yield strength, no obvious directionality; high uniform elongation; low yield ratio; low work hardening.

Influence of Necking Process in Stamping

Influence of Necking Process in StampingDuring necking processing, the metal stamping material at the necking end slides into the female die under the pressure of the punch, the diameter decreases, the wall thickness and height increase, and when the wall thickness of the workpiece is not large, it can be approximately considered that the deformation area is in the plane stress state of tangential and radial compression, mainly tangential pressure. The radial compressive strain is the large strain of zui, while the thickness and length directions are elongation, and the deformation in the thickness direction is greater than that in the length direction.

Due to the effect of tangential compressive stress, the billet is prone to instability and wrinkling during necking; At the same time, the cylinder wall in the non deformation area is prone to instability and deformation due to bearing all necking pressure, so preventing instability is the main problem of necking process.
