Punching device for metals

Abstract

The invention provides a punching device for metals and relates to the technical field of metal machining equipment. The punching device for metals comprises an operating table; a placement plate is disposed at the top of the operating table; fixed plates are fixedly mounted on the two sides of the top of the operating table, one fixed plate is provided with a motor, and a bearing seat is fixedlymounted on the inner side of the other fixed plate; and a threaded rod is fixedly mounted at the output end of the motor through a coupler. According to the punching device for metals, a punching roller is indirectly driven through forward-backward rotation of the motor, thus the punching roller regularly punches a tension part, punching through driving of a traditional oil cylinder is avoided, contamination to the tension part is effectively prevented, the operation workload of maintainers is relieved, and time and labor are saved; and by arranging a punching frame, the up-and-down moving range of the punching roller can be changed, thus punching can be performed on tension parts which need different punching sizes, and the application properties of the punching device are wider.

Description

technical field [0001] The invention relates to the technical field of metal processing equipment, in particular to a stamping device for metal. Background technique [0002] Metal is a material with luster, that is, it strongly reflects visible light, is malleable, and is easy to conduct electricity and heat. The above properties of metals are all related to the free electrons contained in the metal crystals. Since the metal surface is easily oxidized and corroded to rust after long-term use after processing, the metal surface is generally galvanized for rust prevention, while metal sheets, strips, pipes and profiles need to be plastically deformed or separated to obtain the desired shape And size of the workpiece, usually through stamping and stretching and other processing processes. [0003] In the process of metal processing, there is a process that needs to be stamped. The traditional stamping device uses an oil cylinder to drive the stamping plate for stamping. The ...

Problems solved by technology

[0003] In the process of metal processing, there is a process that needs to be stamped. The traditional stamping device uses an oil cylinder to drive the stamping plate for stamping. The oil cylinder body is small but powerful, and can be constant or variable. The adjustment of the output is also convenient and the transmission is free. However, the oil cylinder often leaks oil, which is easy to pollute the metal. Maintenance personnel are required to regularly check the oil leakage of the oil cylinder, which is time-consuming and laborious, and the operation is complicated. The size of stamping is fixed, resulting in a relatively single applicability
