punching die

1. ontinuous dies are basically the same, but the die parts and stamping methods are different. The punching mold is a single-process mold, and its feeding method is completely different from the automatic feeding method of the continuous mold; its positioning method is also different from that of the continuous mold.

The guide posts of the hole mold structure are formal installation. Fixed punch, spring, upper die base and a fixed guide post should be added here. The way the guide posts are processed on this plate is to cut, +0.005 per side, start cutting.

The function of the upper stripper plate is the same as that of the inner stripper plate of the composite mold. It plays the role of protecting the punch, removing material, and pressing material.

The function of the lower template is to interact with the punch to punch out the holes or shapes required by the product. Such as stretching, embossing, half-cut, punching or trimming.

The function of the lower pad is to increase the strength of the lower template and prevent the inserted block (insert) from invading the lower mold base. This board is generally made of CR12 material or 45# and requires heat treatment. The degree of thermal theory is generally 45°-52°. Some companies will skip heat treatment in order to facilitate future product design changes and mold repairs, but this approach is not recommended because it cannot prevent the block from sinking. The function of the lower mold base is the same as that of the composite mold.
