Description

Split type punching upper die, punching and shearing machine and press machine Technical Field The utility model relates to the technical field of stamping dies, in particular to a split type stamping upper die, a stamping and shearing machine and a press machine. Background In the existing stamping equipment, an integral upper die core is generally adopted for processing, and the integral upper die core has excellent rigidity and strength due to the simple structure of integral casting processing. This design ensures that the mould remains stable when subjected to large forming forces, and due to the nature of the integral casting, the repair process is extremely complex and costly once the mould is damaged. In addition, the operability of the integral structure in the aspects of die adjustment and maintenance is poor, and particularly when the grinding rate of the pressing core needs to be adjusted, the integral grinding workload is large, and time and labor are wasted. Such a configuration may require disassembly of multiple components during adjustment, increasing maintenance complexity and time costs. The design of the split type upper mold core obviously improves the flexibility and maintainability of the mold, but the overall rigidity of the split type upper mold core is insufficient compared with that of an integrated structure. This disadvantage in rigidity may cause deformation of the mold under high pressure conditions, thereby affecting the forming accuracy.
