How does a stamping part processing factory make products without burrs-hardware

How can stamping parts processing plants reduce or remove the burrs of stamping products? It is estimated that many friends have heard of negative gap blanking. As long as they have been engaged in stamping dies, many friends are not sure about the real principle. Under normal circumstances, our stamping products have only one direction. Burrs. If you want to remove the burrs in this direction, you can perform the process of pressing the burrs in the mold. If you don't do this, it seems that you can only punch through the negative gap. The burrs will always be produced during the blanking process. , It is difficult to remove, therefore, often press burrs after processing to remove burrs. In view of the problem of the parting surface, the method of deburring has been increasing recently. The following Xiaoshuo introduces a processing method for removing burrs. It is usually called the 'flat pressing method'. This method first performs half-cutting. Usually the punch is slightly larger than the female mold. This state is called'negative gap'. The punch is pressed into the material, and the material is only pressed out to the single side of the concave mold. Formation. At this time, the punching amount of the punch is very important, and it is usually set to 75% or more of the material plate thickness. The next process is a flat pressing process. The operation of the flat pressing process is very simple, but its content is very special. The material is in a half-punched state. This shape is divided into three parts to consider. The virtual punch part, the virtual die part, and the part clamped by the virtual punch and the virtual die are matched by the virtual punch and the virtual die. This part of the material is punched. The process of punching yourself and generating the collapsed angle is the core of the flat pressing process. In order to achieve the ideal flat pressing process, an appropriate half amount of punching in the punching process is required. If it is shallow, virtual punches and virtual dies cannot be formed, and if it is too deep, it will be punched out before flat pressing. The reason for choosing a negative gap is to avoid material seizure in the flat pressing process. In terms of the final finished size of processing , The dimensions of the punched parts are basically the same as the punch size of the half-punching process. It is slightly different from ordinary blanking. In addition, in the cutting edge part of the negative gap punching, we need to do it in the lower die The design of the stripping block can ensure the flatness of the product. Of course, if the product is very small, it is not necessary. Hardware, the stamping parts processing factory with product accuracy up to 0.01MM, 15 years of rich experience makes every product like Bright and perfect as a pearl. Choose, choose to rest assured!
