Description

Punching die and punching machine Technical Field The utility model relates to the technical field of die processing, in particular to a punching die and a punching machine. Background The switch bracket is used as a supporting piece, and needs to meet the functions of supporting, limiting and fixing, so that the switch bracket has various morphological structures, and usually needs to be subjected to hole punching forming on different planes. The punching process can be used for efficiently manufacturing holes with required shapes on the plate, and the functional requirements of the switch bracket in ventilation, heat dissipation, connection and the like are met. When the switch bracket is punched by using a die, the single punching die is adopted for single punching, so that the accuracy and the flexibility of processing are ensured, but only one hole can be processed at a time, the production period is long, the efficiency is low, and the processing cost of unit products is relatively high. The existing die for processing a plurality of holes at one time can finish the processing of the holes at one time, but is suitable for mass production and products with fixed hole sites, and has poor flexibility. Meanwhile, the existing punching lower die is integrated, and after abrasion, the whole punching lower die needs to be replaced, so that the use cost is high. Disclosure of utility model The utility model provides a punching die and a punching machine, which aim to solve the defects in the prior art, and a plurality of mounting holes are arranged on a mounting plate, and then according to the actual processing requirement, the punching needle is arranged in the mounting hole, so that the processing of a plurality of holes can be finished by one-time punching, and the production efficiency is greatly improved. In order to solve the technical problems, the utility model provides a punching die which comprises an upper mounting assembly, an upper fixing plate, a material returning assembly, a punching needle, a lower mounting assembly and a split lower die, wherein the upper mounting assembly is connected with a power output end of processing equipment, the upper fixing plate is connected with one end, far away from the processing equipment, of the upper mounting assembly, a plurality of mounting holes are formed in the upper fixing plate, the material returning assembly is connected with one end, far away from the upper mounting assembly, of the upper fixing plate, one end of the punching needle is clamped in the mounting holes, the other end of the punching needle extends out of the material returning assembly, the lower mounting assembly is fixed on a processing table surface of the processing equipment, the split lower die comprises a lower die main body and a lower mounting block, punching holes matched with the punching needle are formed in the lower die main body, a mounting groove is formed in the lower mounting block, the lower die main body is clamped in the mounting groove, and the lower die main body and the lower mounting block are respectively connected with the lower mounting assembly.
