How to solve the problem of skipping waste in the stamping of metal stamping parts? -Hardware

Dongguan Hardware Co., Ltd., manufacturing and metal stamping parts processing are integrated, and various industrial supplier resources are also available online, including metal mold processing. In the process of metal stamping parts processing, design and manufacturing for many years, the well-known waste phenomenon is a common phenomenon, so today Xiaoshuo will analyze the common waste problems of metal stamping parts for everyone. 1. Stamping processing technicians can easily skip waste. An ejector pin and a spring are added to the punch of the die, and the ejector pin is used to push the waste into the lower mold during the production of the mold. Most of this skipping waste is in the process of discharging, and most of them have produced a relatively simple punching shape. 2. When designing the lower die insert, it will match the punches with equal clearance. In order to prevent the scrap from skipping, make 1 or 2 pairs of symmetrical points in the lower die insert, respectively, which are less than 1/2 of the punching gap, so When stamping and punching waste, the waste is stuck in the lower mold insert due to the small gap stamping. This method can be completed by wire cutting. This method is suitable for punching and processing parts with relatively large shapes and thicker raw materials. However, if it is a thin plate material, some of the above methods to prevent skipping scraps are not very suitable, because the punching gap of extremely thin materials is small. At this time, another method must be selected to prevent it. Stamping technicians can add a lower die auxiliary board below the lower die base when the precision metal stamping parts are stamped to make all possible or even all the blanking holes of the punching parts into a large blanking on the auxiliary board. Frame, weld a material pipe similar to a funnel, and then use an industrial suction device to connect to the material pipe. This method is similar to but different from the punch blowing principle. The detailed method is to make an air channel in the lower die pad, and then drill a downward 45 inclined hole through the blanking hole in the blanking hole that needs to be blown, and the air channel There is no connection with the blanking hole (remember this). When the air is blown down, a negative pressure space is formed to suck down the waste.
