Problems in the processing of precision metal stamping parts:

1. The gap between the convex and concave molds is too small, which can cause thinning and wear. During the stamping process, it is essential to check for changes in the clearance between the molds.

2. The radius of the concave die corner is too small, and there are impact marks on the bending parts of precision metal stamping. Polishing the concave mold and increasing the fillet radius of the concave mold can prevent scratches on metal stamping bent parts.

3. When the convex mold enters the concave mold too large, surface scratches may occur on the parts, so it is necessary to reduce the amount of convex mold entering the concave mold appropriately without being affected by rebound.

4. When the bending direction of metal stamping is parallel to the rolling direction of the material, cracks will appear on the surface of the part, thereby reducing the surface quality of the workpiece. When precision metal stamping bends more than two parts, the angle between the metal stamping bending direction and the rolling direction should be as close as possible.

5. When continuously stamping and bending soft materials such as copper and aluminum alloys, metal particles or residues are prone to adhere to the surface of the working area, causing significant scratches on the object. At this point, carefully analyze the shape of the working part and the condition of the lubricating oil, resulting in particles and residues in the blank without scratches.

6. In order to meet the requirements of wood processing accuracy, metal stamping and bending of bottom stamping materials are often used. Therefore, when metal stamping bends, the springs, locating pin holes, plates, and return holes on the raw material plate are affected. It has become an indentation, so adjustments need to be made.

7. When using a burr surface as the outer surface for metal stamping and bending, the parts are prone to cracking and scratching; Therefore, the burr surface should be used as the inner surface for metal stamping bending.

Stamping parts are mainly manufactured through stamping with low material consumption, and their parts are lightweight and have good rigidity. In addition, after plastic deformation of the sheet metal, the strength of the stamped parts is improved. The size accuracy is good, the size of the same module is uniform, and the interchangeability is good. It can meet general assembly and usage requirements without further mechanical processing.

I believe everyone knows about precision metal stamping parts, but do people only know what precision metal stamping parts are? How much do people know about the advantages of precision metal stamping parts? Only by understanding the advantages of stamped parts can we make good use of them and facilitate ourselves.

1. Precision metal stamping parts have good surface quality and a smooth and beautiful appearance.

The good surface quality of precision metal stamping parts also provides powerful conditions for painting, electroplating, or other surface treatments.

2. Precision metal stamping parts are manufactured under the premise of low material consumption, with light weight but good rigidity.

After deformation, the internal structure of the scripture was improved, resulting in relatively better strength of the stamped parts.

3. The dimensional accuracy of precision metal stamping parts is relatively accurate. Under the same mold, the size is the same and can be interchanged.

Precision metal stamping parts can meet the assembly requirements of general accessories without further processing, and the size and dimensions of precision metal stamping parts do not require secondary processing.

Reducing the number of stamping processes for precision metal stamping parts is a good measure to save investment and energy consumption by reducing the number of precision metal stamping parts, saving tooling, simplifying the transmission device of stamping processes, reducing operators and stamping footprint. Therefore, stamping manufacturers can consider stamping process design as an important way to reduce automotive manufacturing costs, and even improve product design to meet manufacturing technology requirements.

Nut stamping parts release external forces from sheet metal, amorphous materials, pipe fittings, aluminum profiles, etc. through punching machines and grinding tools, resulting in changes or separations in plastic shape, thus obtaining the required samples and specifications of steel parts (stamping parts) for forming, production, and processing stamping molds, and forging them into the same plastic deformation production processing (or working pressure production processing), collectively referred to as forging. The key materials for stamping molds are cold pressed and hot pressed thick steel plates and steel chains. The key to stamping molds is to classify them according to processing technology, which can be divided into two categories: separated process flow and forming process flow.

How to reduce the manufacturing cost of precision metal stamping parts?

1. Control costs by improving the automation technology and high-speed level of the entire stamping die process.

2. The design plan is to produce and process grinding tools separately for each steel component.

3. Control costs by increasing the utilization rate of raw materials.

4. Improve the level of stamping molds, reduce process flow, and extend the service life of grinding tools.

5. Improve the precision level of processing technology.
