What's wrong with the uneven warpage of Personal income stamping parts of metal material sheet processed by stamping parts? What methods are generally used by stamping parts factories to handle? Come and master it.

At the moment of contact with the mold base and cavity, the metal composite material first undergoes stretching and bending, followed by breaking and tearing. Due to the various forces of deep drawing, bending, and horizontal extrusion forming, the product exhibits wavy patterns during material development, resulting in warping of the product. There are several reasons for warping caused by general stamping parts:

1. Warpage caused by large punching gaps

Improvement method: During punching, the mold seat and pressure plate can be firmly pressed, and the sharp edge can be maintained. Hardware parts processing factories can receive excellent practical results.

2. Warpage caused by counter cone on the edge of the cavity hole

When the parts are positioned according to small specifications, the jugular vein needs to be narrowed towards the management center, causing bending due to CNC hardware parts processing. Just repair the grinder

3. Warpage caused by uneven shear stress around the parts due to the complex structure of stamping parts

The method of handling is to expand the pressing force.

4. Warpage caused by internal ground stress in raw materials

When the processing method is beneficial, use a leveling machine to level it.

5. Warpage caused by oil, gas, and poor contact

Cleaning the surface of raw materials for stamping molds, evenly applying oil, and setting vent holes can remove warping conditions. Before clarifying the layout diagram for CNC hardware parts processing continuous molds, a punching needle overlay diagram should be made first. The purpose of making this image is to ensure that all waste is washed away and detailed products are obtained. The first step is to clarify the burr surface of the product, the direction of the product grain, the horizontal distance, the total width of the strip, the reference point of the product, the effective edge contact, and the feeding direction. It is necessary to fully consider the order of punching needles, the order of bending, and the precise positioning of holes and edges.
