Numerical control punching machine and punching method thereof

Abstract

The invention relates to a numerical control stamping machine and a stamping method thereof. The numerical control stamping machine comprises a worktable top, a support, a hydraulic rod, a four-jaw chuck, rectangular fixing blocks, stamping end assemblies, pressing assemblies and supporting assemblies, wherein the support is movably arranged at one side of the bottom end of the worktable top; thehydraulic rod is arranged at one end of the support; the four-jaw chuck is welded to the bottom of the hydraulic rod; the bottom of each clamping jaw of the four-jaw chuck jaw is of a plane design andis fixedly connected with one rectangular fixing block through spot welding; each stamping end assembly is arranged at the center position of the corresponding rectangular fixing block; the pressingassemblies are arranged at the position, on the two sides of the corresponding stamping end assembly, of the bottom outer wall of each rectangular fixing block; the supporting assemblies are welded onthe outer wall of the four-jaw chuck at equal intervals; an installation groove is formed in the center position of each rectangular fixing block; the stamping end assemblies are positioned in the installation grooves; and an abutting pressing block is fixed on the bottom outer wall of each installation groove through spot welding. According to the numerical control stamping machine and the stamping method thereof, multi-station feeding-type stamping can be achieved, and the concentricity of stamping heads can be rapidly checked.

Description

technical field [0001] The invention relates to the technical field of punching equipment, in particular to a numerically controlled punching machine and a punching method thereof. Background technique [0002] Stamping is a process in which the driving device drives the stamping head to apply external force to the plate and other components to cause plastic deformation or separation. It is one of the main methods of metal plastic processing or pressure processing, and it also belongs to material forming engineering technology. In order to effectively increase the efficiency of stamping, some stamping equipment on the market has emerged as the times require. At present, the most common stamping equipment on the market is the stamping machine, which is mainly divided into two types: motor drive and hydraulic drive. [0003] However, the stamping machines in the current market have the following problems during use: a. During the use of traditional stamping equipment, the pos...

AI Technical Summary

Problems solved by technology

[0003] However, the stamping machines in the current market have the following problems during use: a. During the use of traditional stamping equipment, the position between the stamping head and its connectors is relatively fixed, and it is impossible to realize multi-station feed stamping. Moreover, the use of the stamping head is relatively unique, resulting in a limited range of stamping, which cannot be applied to different stamping requirements, and is not practical; b. Traditional stamping equipment, in the long-term use process, will cause the stamping head to appear eccentric , this will affect the quality of stamping, and the traditional stamping equipment cannot quickly check the concentricity of the stamping head, or the inspection method is more troublesome, and the entire stamping head needs to be disassembled
