Abstract

The invention discloses a countermark die with an overload protection device, relates to a countermark die and aims to solve the problems that blocking run is easy to occur, the die is easy to damage and the casualty accident is caused when a thin steel plate which is 0.1mm thick is countermarked on a crank press. A lower die is connected with the upper surface of a lower die plate; a positioning plate is connected with the upper surface of the lower die; lower ends of guide pillars are respectively and fixedly arranged in mounting holes I of the lower die plate, and upper ends of the guide pillars are respectively arranged in guide sleeves; each guide sleeve and the corresponding guide pillar are in sliding fit; upper ends of the guide sleeves are respectively and fixedly arranged in mounting holes II of an upper die plate; a die shank is connected with a threaded hole of the upper die plate; a base plate, an upper die fixing plate and the upper die plate are connected; an upper die is fixedly arranged in a stepped hole of the upper die fixing plate; the lower surface of the upper die is provided with a cross-shaped bulge; a safety pin and a safety plate are arranged above the stepped hole of the upper die fixing plate; the upper end of the safety pin is arranged in a central blind hole I of the safety plate; the lower end of the safety pin is in contact with the upper surface of the upper die; the upper surface of the safety plate is in contact with the lower surface of the base plate. The countermark die is used for countermarking the thin steel plate which is 0.1mm thick.

Description

technical field [0001] The invention relates to an engraving mold, in particular to an engraving mold with an overload protection device. The invention belongs to the technical field of machining stamping dies. Background technique [0002] Stamping is a process method of mechanical processing. It uses a press to pressurize a metal blank through a mold to cause plastic deformation to obtain parts of a certain shape, size and performance. It is one of the important processing methods in mechanical manufacturing. . There are many types of parts produced by stamping methods, and their forming methods are also varied. According to the types of forming processes, they can be divided into two categories, one is the separation process; the other is the forming process. The forming process refers to the plastic deformation of the material without destroying the material, so as to obtain the required shape and size of the workpiece. The forming process includes bending, deep drawi...
