Trimming die structure improvement

The present invention relates to a trimming die structure improvement, and more particularly to a trimming die suitable for stamping and cutting operations to form a predetermined shape and structure, and having both wear resistance and high hardness effect.

In order to adapt to the advent of the era of meager profit, all walks of life are pursuing their own cost reduction. The most effective way for manufacturing is to reduce costs by mass production, and the first condition for mass production must provide the mold for casting this product. Mass production is carried out by either stamping or potting, but today's product types must be constantly updated, especially consumer electronics, so the cost and efficiency of mold manufacturing is a non-negligible step.

Stamping is a metal processing method in which the material is cut, bent or molded into the shape and size of the finished product by the method of heavy hammer processing. Today, the stamping processing is widely used in various products, including Electronic parts, locomotive parts, household appliances, factory production machines, etc. are all stamped by processing technology, and the processing method of this stamping gradually replaces the previous processing methods such as die-casting and forging. It can be seen that stamping processing has a place in current product manufacturing. .

The general trimming die is made of S45C (medium carbon steel) material, and the trimming die is composed of the upper die plate and the lower die plate, while the upper die plate is provided with punches for stamping materials, and the lower die plate corresponds to the lower die plate. The punch is provided with a die hole group, wherein the die hole group is a cutting edge portion; wherein the die plate group of the lower template is formed by cutting by any one of an NC electric discharge machine or a laser processing machine; The lower template is loaded with the material. During the stamping process, the upper template is pressed against the lower template, so that the punch presses the material to the die hole group, and the blade is cut by the edge portion above the die hole group. Cut, bend, form or extend to obtain finished products.

However, as far as the above is concerned, the general trimming die is made of S45C (medium carbon steel) material, which has the advantages of low cost and shortcomings of toughness and strength. Therefore, when the trimming die is subjected to press forming work, The guiding groove is arranged at the lower template, and the material is placed in the guiding groove, so as to guide the material to the proper position for punching and cutting processing; but it is easily affected by the material factor, and the upper and lower templates are affected by the pressure channel. The blade portion at the top of the die hole group of the lower template is easily damaged. At this time, the lower template must be disassembled for the mold clamping operation, which increases the production cost, takes time and labor, and even affects the life of the mold. It is a big drawback, and it needs to be improved.
