Description

Continuous punching machine convenient to change mould

Technical Field

The invention relates to the technical field of stamping, in particular to a continuous stamping machine convenient for die replacement.

Background

The stamping is a forming processing method which applies external force to plates, strips, pipes, profiles and the like by a press and a die to cause the plates, the strips, the pipes, the profiles and the like to generate plastic deformation or separation, thereby obtaining workpieces (stamped parts) with required shapes and sizes, the stamped parts have the characteristics of thinness, evenness, lightness and strength compared with castings and forgings, the workpieces with reinforcing ribs, undulation or flanging which are difficult to manufacture by other methods can be manufactured by stamping, so as to improve the rigidity of the workpieces, and the process equipment for processing materials (metal or nonmetal) into parts (or semi-finished products) in cold stamping processing is called as a cold stamping die;

the principle of the existing punching machine is to convert circular motion into linear motion, a flywheel is driven by the power of a main motor, a gear, a crankshaft (or an eccentric gear), a connecting rod and the like are driven to run through a clutch so as to achieve the linear motion of a sliding block, and the motion from the main motor to the connecting rod is circular motion. In national production, the stamping process has the advantages of saving materials and energy, high efficiency, low technical requirement on operators and capability of making products which cannot be achieved by mechanical processing through various die applications compared with the traditional mechanical processing, so that the stamping process has more and more extensive application;

common punching machine in market need carry out the material loading through material loading manipulator or manual fit, the wait for clearance of going up unloading process is long, work efficiency is low and waste time and energy, in addition, the last mould and the lower mould of changing the punching machine all need the manual work to replace the installation, the installation mould must be opened the upper die base bottom dead center, closed height must be correct, and avoid eccentric load as far as possible, the mould must fasten firm through the pressure testing inspection, the installation direction mistake leads to the fact the punching machine to damage easily, even cause the injury to the staff.
