What should be paid attention to in the production of hardware stamping parts

Hardware stamping parts are products that we often come into contact with. It is made by cutting, bending, punching, forming and other processes of metal materials in the mold cavity through the pressure of the mold and punch press. So what precautions should be taken in the production of hardware stamping parts

1. Regularly check the mold installation base of the punching machine turntable and stamping parts, as well as the coaxial accuracy of the upper and lower turntables

2. Hardware stamping parts should be strictly inspected before installation and use, and the guide sleeve and mold of the drawn stamping parts should be carefully checked for good lubrication

3. In order to prolong the service life of the tension and compression parts, the spring of the mold should also be replaced regularly to prevent fatigue damage of the spring from affecting the use of the tension and stamping parts

4. When installing the mold, stamping personnel should use soft metal manufacturing tools to prevent damage to the stamped parts during the installation process by tapping and crushing

5. When the convex and concave die edges of stamping parts are worn, they should be stopped in a timely manner and sharpened in a timely manner. Otherwise, it will expand the wear of the mold edge, accelerate mold wear, and reduce the quality and service life of the stamping parts

The four common stamping processes for metal stamping parts

Metal stamping parts are a processing method with high production efficiency, less material loss, and lower processing costs.

. More suitable for mass production of parts, facilitating mechanization and automation, with high accuracy, and also facilitating post processing of parts

Generally, there are four processing techniques for metal stamping parts in the production process:

1. Blanking: a stamping process that separates the sheet metal (including punching, cutting, trimming, and sectioning).

2. Bending: A stamping process that involves bending a sheet metal along a bending curve to form an angle and shape

3. Drawing: A stamping process that transforms flat sheet metal into various open hollow parts, or further changes the shape and size of the hollow parts

4. Local forming: A stamping process that uses various local deformations with different properties to change the shape of a blank or stamped part (including flanging, bulging, leveling, and other processes)
