Punch press

Abstract

The invention discloses a punch press which comprises a punching mechanism, a workbench, a terrace die, a partition board and a telescopic rod, wherein the terrace die is arranged on the surface of the operating platform; the partition board sleeves the outer side of the terrace die; one end of the telescopic rod is connected with the partition board, and the other end thereof is connected with the punching mechanism; the maximum telescopic length value of the telescopic rod is less than or equal to the maximum value from the joint between the telescopic rod and the punching mechanism to the vertical height of the upper surface of the terrace die; the length value of the telescopic rod main body is less than or equal to the length value from the joint between the telescopic rod and the punching mechanism to the joint between the telescopic rod and the partition board. According to the utility model, the punching mechanism goes up and down to drive the partition board to move so as to drive a workpiece to move; a slide bar punches the workpiece to a trough, so that the problem that the workpiece is liable to being clamped with the terrace die after punched is solved, and the manual labor intensity is reduced; the punch press is high in degree of automation and simple and practical in structure.

Description

technical field [0001] The invention relates to a stamping machine. Background technique [0002] The principle of the stamping machine is to drive the flywheel through the motor, and through the clutch, the transmission gear drives the crank linkage mechanism to move the slider up and down, and drives the drawing die to form the steel plate. The so-called double action means that the press has two sliders, which are divided into an inner slider and an outer slider. The inner slider drives the punch or die of the mold, and the outer slider drives the blankholder on the mold. When the blank holder first moves to press the edge of the steel plate, the inner slider moves again to stretch. [0003] Stamping relies on presses and molds to apply external forces to plates, strips, pipes, and profiles to cause plastic deformation or separation to obtain workpieces (stampings) of required shape and size. [0004] Stamping processing is a production technology that uses the power of...

AI Technical Summary

Problems solved by technology

The stamping mechanism rises after stamping, and the telescopic rod pulls the partition to rise, and the partition separates the workpiece from the punch, which solves the problem that the workpiece is easily stuck with the punch after stamping, reduces the labor intensity, and has a simple and practical structure.
