Stamping machine tool with buffering function

Abstract

The invention discloses a stamping machine tool with a buffering function, and belongs to the technical field of machine tools. A plurality of buffering devices are arranged between a lower die base and an upper die base, each buffering device is composed of an outer guide sleeve and an outer guide column which are movably arranged in a sleeved mode, a lower buffering body and a lubricating agent arranged between the outer guide column and the lower buffering body in a filling mode are arranged inside each outer guide column, and an upper buffering body is arranged inside each outer guide sleeve. When the upper die base is pressed downwards, the upper buffering bodies and the lower buffering bodies are matched to achieve a double buffering effect on all the buffering devices, most impact force is weakened, the buffering effect on the stamping position is achieved, and the bottom of the machine tool is effectively prevented from being subjected to large impact force; and the lubricating agents arranged inside the outer guide columns in the filling mode not only achieve the buffering effect on downward pressing, but also achieve the lubricating effect on the movement between the outer guide sleeves and the outer guide columns, and the phenomenon that the hole diameter of the guide sleeves is increased due to strong stamping friction force is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of machine tools, more specifically, to a stamping machine tool with a buffer function. Background technique [0002] A machine tool refers to a machine that manufactures a machine, also known as a machine tool or a tool machine, and is customarily referred to as a machine tool. Among them, the stamping machine tool is mainly for the production of plates. Through the mold, it can make blanking, punching, forming, deep drawing, trimming, fine blanking, shaping, riveting and extrusion parts, etc., which are widely used in various fields. [0003] During the working process of the original stamping machine tool, the die is pressed down to give a large impact force to the workbench. The die of the stamping machine tool is not equipped with a corresponding protection device during the falling process, so that the guiding sleeve and the guide post are directly punched. touch. The friction generated during the st...

AI Technical Summary

Problems solved by technology

The friction generated during the stamping process increases the hole diameter of the guide sleeve, causing the first mold and the second mold to loosen during the stamping process; at the same time, due to the poor cushioning effect, when the parts are stamped, the entire machine tool will be damaged. Vibration causes the frame under the workbench to collide with the ground to produce loud noises, which affects the working environment of the staff and brings discomfort to the staff. The existing stamping machine tools are deficient in buffering and shock absorption. Can't achieve good cushioning effect
