Causes of chip jumping in hardware stamping dies of hardware manufacturers

Hardware undertakes all kinds of precision metal stamping parts_Today Xiaoshuo will take you to understand the reasons why metal stamping dies produce jumping chips: the jumping chips of metal stamping dies refer to the molds in high-speed production. After the cutting and cutting are completed, they should stay The material inside the knife edge jumped out and fell onto the mold surface. The phenomenon of chip jumping is a common undesirable phenomenon in metal stamping. Its causes are various. Some scraps are caused by poor mold design, some are caused by poor raw materials, and some are caused by stamping operators. of. The following hardware stamping manufacturers will take you to analyze the reasons for the jumping chips in the hardware stamping die. 1. Abnormal scratches or bumps between the punch or other parts of the metal stamping die and the raw material cause small waste, which is mainly due to the fact that the punch does not have a corresponding structure when it needs to excessively act on the raw material. 2. The knife edge gap of the metal stamping die is too large, and the design section determines the knife edge gap improperly (a reasonable gap is 4-6% of the material thickness). In the case that the metal stamping die is very smooth, due to the frequent friction between the material and the inner surface of the knife edge, the inner surface of the knife edge is worn out, resulting in a large gap between the knife edge. 3. Since the raw material has been surface-treated before stamping, the surface treatment layer and the material itself still have a certain non-structural comprehensive phenomenon, which will cause the edge of the material to separate and fall off. There is also the fact that the punch of the metal stamping die is magnetic, which generates suction to the material and generates jumping chips. Hardware, 15 years of hardware stamping industry experience, strict quality control process, daily output of 3 million times, is a reliable choice in the hardware stamping industry. support hotline:
