First of all, the automobile stamping parts designed must be conducive to improving the utilization rate of metal materials, reducing the variety and specifications of materials, and reducing the consumption of materials as much as possible. When permitted, stamping parts can be made of low-cost materials, so that parts can be blanked as much as possible without waste and with less waste.

First of all, the automobile stamping parts designed must be conducive to improving the utilization rate of metal materials, reducing the variety and specifications of materials, and reducing the consumption of materials as much as possible. When permitted, stamping parts can be made of low-cost materials, so that parts can be blanked as much as possible without waste and with less waste.

Of course, the design of automobile stamping parts must also meet the product use and technical performance, and can be easily assembled and repaired. At the same time, it is advantageous to use existing equipment, process equipment and process flow to process it as far as possible, and to prolong the service life of the die.

In addition, the design of stamping parts to ensure the normal use of the situation, as far as possible to make the size accuracy and surface roughness level requirements lower, and conducive to product interchange, reduce waste, ensure product quality stability, reduce its cost and improve value.

The automobile stamping part introduces what causes the coiling phenomenon of the stamping part in the general production process?

1. There are irregular damages at the edge of the material and materials beyond the qualified quality standards.

2. Bubble bulging on the back of the roll when foreign body falls in due to stick sliding

Thirdly, foreign bodies on the surface or inside of the steel mix with foreign bodies outside the material. When the foreign bodies are peeled off, the coil is like a scar uncovered. It is a tragic sight.

4. When a foreign body sticks to the stick, the stick marks are caused by the depth of the surface caused by the foreign body, and then obvious marks are produced.

5. Scratches on the surface of sticks or foreign bodies usually result in wrinkles or deformations at the corners of rolls due to uneven stress, which in turn leads to the breakage of the corners of rolls.
