Adaptive High Precision Stamping CNC Machine Tool

Abstract

The invention provides a self-adaptive high-precision punching numerical control machine tool. The self-adaptive high-precision punching numerical control machine tool comprises a machine tool body, alower machine body and an upper machine body, wherein a workbench is arranged on the lower machine body, the workbench is connected with a lower punching assembly, and the lower portion of the lowermachine body is connected with an upper punching assembly so as to realize numerical control punching operation on workpieces on the workbench; the lower punching assembly comprises a lower bearing table fixed to the workbench, a lower die is arranged on the lower bearing table, a lower accommodating groove for accommodating the lower die is formed in the upper surface of the lower bearing table,and a plurality of lower self-adapting assemblies positioned between the lower die and the lower bearing table are further arranged; and the upper punching assembly comprises an upper bearing table fixed to the upper lathe body, the upper bearing table is provided with an upper die, the upper bearing table is provided with a hydraulic driving part for driving the upper die to punch, and an upper self-adapting assembly is arranged between the hydraulic driving part and the upper die. Therefore, according to the self-adaptive high-precision punching numerical control machine tool, the effectivebuffering during punching can be provided, the self-adaptive function can be provided during punching, the adaptability is wider, and the punching yield is higher.

Description

technical field [0001] The invention relates to the technical field of stamping machine tools, in particular to an adaptive high-precision stamping numerical control machine tool. Background technique [0002] Stamping is a forming processing method that applies external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation to obtain workpieces (stamping parts) of required shape and size. Stamping and forging belong to plastic processing (or pressure processing) and are collectively called forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel sheets and strips. Among the steel products in the world, 60-70% are plates, most of which are stamped into finished products. The body, chassis, fuel tank, radiator fins of the car, the steam drum of the boiler, the shell of the container, the iron core silicon steel sheet of the motor and electrical appliances, etc. are all stamped. There are also a large ...

AI Technical Summary

Problems solved by technology

[0004] However, the current stamping devices often have certain defects in use: the current stamping dies are relatively fixed and cannot be adapted according to the strength and hardness of the stamping parts, which may easily lead to stamping failure
