1. Stamping manufacturing has high efficiency, practical operation is relatively convenient, and it is easy for mechanical automation and automation technology. This is because precision metal stamping is completed by stamping molds and stamping equipment. The stroke of a regular press can reach dozens of times per minute, while high-speed press can reach hundreds or even thousands of times per minute. Each stamping stroke can be obtainedPrecision metal stampingComponents.

2. During the stamping process, due to the mold ensuring the dimensional and shape accuracy of precision metal stamping parts, the surface quality of precision metal stamping parts is not easily damaged. Generally, the service life of the die is long, the stamping quality is stable, the interchangeability is good, and the die is "exactly the same".

3. Stamping can produce and process parts with relatively large specifications and complex shapes, such as watches, timers, car side beams, etc. In addition, under stamping conditions, the cold deformation hardening compressive strength and strength of the raw materials are both very high.

4. Stamping generally does not produce debris, consumes less material, and does not require other heating equipment. It is an energy-saving material, energy-saving processing method, and low-cost precision metal stamping part.

Common problems in precision metal stamping processing:

Common problems in metal stamping processing include: deformation and burrs of precision metal stamping parts; Warping, surface wear, angular deformation, etc; Wrinkles on the flange of the deep drawn part, wrinkles on the deep drawn wall, damage to the deep drawn wall, tensile cracks, and uneven expansion shape.

The method to solve common problems: Mold design should have reasonable clearance values between convex and concave molds, fillet radius, and machining accuracy. When designing bending molds, effective measures should be taken to reduce rebound on the mold, and reasonable rounded corners should be designed to prevent bending. When deep drawing, use pressure edges to prevent medium pressure; Proper lubrication to reduce drawing resistance and prevent mold adhesion or pulling of workpieces; Use professional stamping oil that meets the process requirements.
