Cutting device capable of achieving action of cutter and female die synchronously

Abstract

The invention discloses a cutting device capable of achieving the action of a cutter and a female die synchronously. The cutting device comprises a base and a telescopic device, wherein a connecting block is slidably arranged at the upper portion of the base; the telescopic device is fixed on the base; a telescopic end of the telescopic device is fixed on the connecting block; the cutter and a driving lifting mechanism are vertically arranged and fixed on the side, away from the telescopic device, of the connecting block; a connecting plate is fixed on one side of the base; the female die is arranged above the connecting plate; a driven lifting mechanism is arranged on the side, facing the base, of the female die; a through hole is formed in the connecting plate; a bolt is connected to thelower portion of the female die and movably penetrates through the through hole of the connecting plate; the bolt is sleeved with a spring; the top end of the spring is fixed on the bottom wall of the connecting plate; and the bottom end of the spring is fixed on the bolt. According to the cutting device capable of achieving the action of the cutter and the female die synchronously, a punching unit is not used as an obstacle in the stretch bending direction of a section bar, and after the section bar is drawn and bent, the cutter can be moved and the female die can be lifted synchronously soas to cut a notch in the section bar; and the cutting device capable of achieving the action of the cutter and the female die synchronously is simple and low in cost, the move time of the punching unit is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of punching and processing parts, in particular to a cutting device for simultaneously realizing the actions of a cutting knife and a die. Background technique [0002] In actual production, it is necessary to add punching notches to the three-dimensional bending parts as a subsequent process positioning. The three-dimensional bending parts are required to be free of obstacles in the bending direction, otherwise the parts will collide with obstacles during the forming process. In the currently adopted solution, the entire punching unit is movable. When bending, the entire punching unit is moved to avoid the bending direction of the three-dimensional part. After the bending is completed, the punching unit is moved to the working position, and then the notch is punched. In this punching method, the entire punching unit needs to be moved, the cost of punching the gap is high, and the working cycle time is long,...
