The invention relates to the field of cold stamping dies and particularly relates to a terrace die mounting structure on a cold stamping die. The terrace die mounting structure comprises a terrace die body; the terrace die body is formed by a fixing part and a punching part, a terrace die fixing plate for positioning the terrace die body, a die machine body and a material pressing plate; the terrace die fixing plate is fixedly mounted on the die machine body; the material pressing plate is mounted on the die machine body; the fixing part and the terrace die fixing plate of the terrace die body are assembled according to the tolerance of H7 / m6; a chamfer is arranged at the end part of the fixing part of the terrace die body and a through hole with a part of a thread on a countersunk head is arranged at the end part of the punching part of the terrace die body; a threaded hole is formed at the corresponding position of the die machine body; and a fixing screw is used for fixing the terrace die body on the die machine body through the through hole with the countersunk head thread. According to the terrace die mounting structure, when a terrace die needs to be maintained or replaced, the material pressing plate and the fixing plate do not need to be detached and the production efficiency is improved.
Description
technical field [0001] The invention relates to the field of cold stamping dies, in particular to a punch mounting structure on the cold stamping die. Background technique [0002] In the cold stamping die, the large-hole punch needs to be repaired, or the large-hole punch needs to be disassembled due to the need for production change. [0003] The main structure of the big hole punching die includes the body, punch, punch fixing plate, and binder plate. The punch fixing plate is used for punch positioning. It is installed on the body through fixing screws and pins, and the punch passes through steps and fixed. The part is installed on the punch fixed plate, and the punched part can pass through the blanking plate during operation. The large-hole punch will be worn out during the production process and needs to be disassembled and repaired. Before the mold is repaired, the binder plate and the punch fixing plate must be disassembled before the punch can be taken out for mai...
