The role of the pressing groove of the stamping die in the stamping processing factory-hardware

With the advancement of technology, the current stamping processing plants normally make continuous stamping dies. At the same time, a set of molds will have 7-8 templates. Generally, the stripper plate of single-punch die does not have a blanking groove. For example, ordinary engineering molds do not have a blanking groove, but why do continuous molds need to design a blanking groove? Xiaoshuo sorted out a few points for your reference: Why does the engineering mold not need a press groove? This is because the materials stamped by engineering dies are generally thicker, rougher, and less precise. They do not need to stamp a strip as long as the continuous die, and the engineering dies are also relatively small. The template size is not as long as the continuous die. The size required by the product The accuracy is not as high as the continuous mold, and it is easier to repair and debug. Therefore, the engineering mold generally only needs the finite column and does not need the press groove. For continuous molds, it needs to be mass-produced, and the product accuracy is higher than that of engineering molds. Therefore, the accuracy requirements of the mold are relatively high, and the blanking groove is a way to improve the accuracy of the mold. Therefore, the continuous mold generally uses the press groove and the limit column to control the gap of the product strip in the mold. Why do continuous molds need to design a pressing groove? Because when the continuous die stripper plate is in contact with the lower template and presses the material, strong pressure does not mean that the material can be completely pressed. Therefore, the stripper plate of the continuous die and the surface contacting the lower template will generally have a thickness of 0.05mm to The 0.08mm depth pressing groove (can be adjusted according to the material thickness), commonly known as 'pre-compressionThe gap in the middle is uniform, so that the die can fully compress the material when cutting, and prevent the punch and knife from being worn out due to uneven pressing, and the bright band is not neat and so on. Hardware is a stamping processing factory that has produced 20,000+ sets of continuous stamping dies. With 15 years of rich experience, it has served thousands of customers in more than 20 industries. In the automobile, communication, electronics, electrical appliances and other industries, the use of skilled technology and enthusiastic service cooperation makes customers from recognition to trust.
