Metal stamping parts are a processing method with less material loss, higher production efficiency, and lower processing costs. This specific processing method allows better efficiency in achieving mechanization and automation to a high standard simultaneously. Consequently, the results are realized with high precision and facilitate the post-processing of parts. Therefore, the method is ideally more suitable for the mass production of parts. In the production process of general metal stamping parts, there are the following processing techniques:

1. Punching: The stamping process separates the sheet material, including punching, blanking, trimming, cutting, etc.
2. Bending: This stamping process bends the sheet to a certain angle and shapes along the bending line.
3. Stretching: Turn the flat sheet into various open hollow parts or further change the shape and size of the hollow parts.
4. Fine blanking: For products with high blanking precision and large size and surface light volume requirements, the drawing requirements can be met through the fine blanking die.
5. Partial forming: the stamping process uses various local deformations of different properties to change the shape of the blank or stamping part, including flanging, bulging, leveling, and shaping processes.

A Complete Buying Guide for Metal Stamping Parts China :

Suppose you are looking for a manufacturer to fill all customized metal stamping parts for your production or business. Then you have come to the right place. This guide introduces all aspects of metal stamping parts in detail, and It will be of great help to you, so let's read on.

1. Introduction to Metal Stamping Parts

Metal stamping parts refer to molds used for steel/non-ferrous metals and other plates at room temperature. The required shape is formed by the pressure required for processing the press provides. Metal stamping technology has the advantages of high production efficiency, convenient operation, easy mechanization, and automation. This is because metal stamping depends on stamping dies and stamping equipment.

Metal stamping has become a popular manufacturing process in recent years. It is considered a cold processing technology, which means just like other cold-working techniques, it will not produce heat-related changes to the metal workpieces used. Therefore, there is no risk of heat-related changes in metal stamping. Compared with other machining and plastic processing methods, it can be stated firmly that stamping has many unique advantages both technically and economically.

2. How Metal Stamping Parts Works

Metal stamping parts are a relatively simple manufacturing process. Its working principle is directly or interactively connected with the mold fixed on the mold and connects with the punch slider through the die handle. The zero point fixed on the mold constitutes the mold, the pressure plate is fixed on the press table, and the upper and lower molds are directed and guided.

The strip is sent to a position corresponding to the fixed material during work. When the upper mold and the slider are lowered together, first press down to discharge the material, and then the material is swollen and recessed to obtain work. The workpiece is stuck on the punching machine, and the waste is also on the punching machine.

When the upper mold rises, the workpiece is ejected out of the cavity through the spring from the top. Use the spring elasticity of the unloading plate to remove the closed waste material on the punch, and then remove the workpiece to complete the entire blanking process. When the workpiece is lifted by the spring, the workpiece is ejected from the top plate by the spring, and the workpiece is taken out by the elastic force of the spring.

3. Benefits of Metal Stamping Parts

(1) For cold stamping, the product is no longer cut, or only a small amount of cutting is required.
(2) Uniform strength, no obvious direction, high uniform elongation, low processing harden-ability.
(3) The thickness of the material used is accurate and uniform, and the surface is smooth, with no spots, no scars, no scratches, no surface cracks, etc.
(4) CNC laser cutting has high precision, high speed, clean, and neat cutting surface, and the surface roughness is only tens of microns without mechanical processing.
(5) The use of composite molds, especially multi-station molds, can complete multiple stamping processes on one press, with high production efficiency and low production costs.

4. Design Principles of Metal Stamping Parts

(1) Must meet the use and technical performance of the product and be easy to assemble and repair.
(2) Use existing equipment, process equipment, and process flow as much as possible to process it, which is conducive to extending the service life of the die.
(3) Under the condition that the stamping parts can be used normally, try to lower the dimensional accuracy and surface roughness levels. It is conducive to exchanging products, reducing waste, and ensuring product quality.
(4) The designed stamping parts should help improve the utilization rate of metal materials, reduce the variety and specifications of materials, and reduce the consumption of materials to the greatest extent.
(5) The stamping parts should be simple in shape and reasonable in structure to simplify the mold structure.

Simplify the number of tools, facilitate the stamping operation, and facilitate mechanized and automated production to improve labor productivity.

5. Types of Metal Stamping Parts in the Market

With the continuous technological development of the metal products industry, metal stamping equipment and technology is constantly improving.

There are many such small factories near some automobile factories or tractor factories.
(6) Special stamping enterprises: such as the stamping of aviation parts, etc. But these craft factories are also included in some large factories.

7. How to Troubleshoot Metal Stamping Parts

Generally speaking, common problems of metal stamping parts include scratches, burrs, line offset, bumps, twists, wrinkles, etc. In daily production, there will be situations where the size of the punching hole is too large or too small, and the size of the punch is quite different.

These problems should be solved from the following aspects: considering the design dimensions of the forming convex and concave molds, the processing accuracy, and the blanking gap.

(1) When the punching edge is worn, the tensile stress on the material increases, and the tendency of the stamping parts to turn over and twist increases. When turning over, the size of the punching hole will become smaller.
(2) For the pressure of the material, the material will be plastically deformed, increasing the size of the punching hole, and when the pressure is reduced, the size of the punching hole will become smaller.
(3) The shape of the edge of the punch edge. If the end is trimmed with an angle or arc, the punching force is not easy to turn over or twist because the punching force is slowed down, so the punching size will become larger. When the end of the punch is flat (no slope or arc), the punching size will be relatively small.

8. Methods of Restraining Stamping Parts from Turning over and Twisting

(1) Reasonable design of the mold: In the progressive mold, the arrangement of the blanking sequence may affect the accuracy of the stamping parts. For the blanking of small parts of stamping parts, generally, a larger area of ​​punching is arranged first, and then a smaller area of punching is arranged to reduce the impact of the punching force on the forming of the stamping part.
(2) Compacting the material: A material-containing gap is opened on the discharge plate to overcome the traditional mold design structure. The material can be pressed tightly when the mold is closed.
(3) Adding a strong pressure function: increasing the size of the press part of the discharge insert to increase the pressure on the material on the side of the die to prevent the stamping part from turning over and twisting during punching.
(4) The edge of the punch is trimmed with an angle or arc: this effectively reduces the buffer cutting force. By reducing the buffer cutting force, the tensile force on the material on the side of the die can be reduced to suppress the production of stamping parts. The effect of turning material and twisting.
(5) In daily mold production, care should be taken to maintain the sharpness of punching convex and concave die-cutting edges.
When the punching edge is worn, the tensile stress on the material will increase, and the tendency of the stamping part to turn over and twist becomes greater.
(6)Unreasonable or uneven blanking clearance is also the cause of turning over and distortion of stamping parts, which must be overcome.

9. How to Verify Quality of Metal Stamping Parts

(1) Visual inspection: Visual inspection is mainly used to find the abnormal appearance and macro defects of stamping parts.
(2) Inspection tool inspection: Put the stamping parts into the inspection tool and inspect the stamping parts according to the operating requirements of the inspection tool manual.
(3) Polishing of flexible gauze: wipe the surface of the outer cover with clean gauze,
Use a flexible sand net to close the surface of the stamping part and grind it to the entire surface in the longitudinal direction.
Any pitting indentation will be easily found.
(4) Touch inspection: wipe the surface of the cover with clean gauze,
When inspecting, you need to wear touch gloves and touch the surface of the stamping part along the longitudinal direction of the stamping part.
This inspection method depends on the experience of the inspector.
If necessary, oilstone can polish the detected suspicious area and verify it. This is an effective quick inspection method.
(5) Whetstone polishing: first, wipe the surface of the outer cover with clean gauze. Then whetstone is polished, and the areas with arcs and hard-to-reach places are polished with relatively small whetstones.
The direction of whetstone grinding is basically along the longitudinal direction. It fits well on the surface of the stamping parts; some special places can also be supplemented with horizontal grinding.
