Problems solved by technology

[0003] The purpose of the present invention is to solve the shortcomings in the prior art, such as: the existing stamping device does not clean the burrs in time after punching the metal after hot forging, and when the forging is cooled, the deformation resistance increases, making deburring very difficult. The trouble of deburring the tool is relatively large, and the efficiency of deburring is low, and a stamping device for hot forging is proposed

Abstract

The invention discloses a punching device for hot forging. The punching device comprises a worktable. Supporting rods are fixedly connected with the worktable are symmetrically arranged on the lower side of the worktable. A lower die holder is arranged on the upper side of the worktable. Guide sleeves fixedly connected with the lower die holder are symmetrically arranged on the upper side of the lower die holder. Guide columns connected with the guide sleeves in a sliding manner are inserted into the upper ends of the guide sleeves. An upper die holder fixedly connected with the guide columnsis arranged at ends, far from the guide sleeves, of the guide columns. A female die is arranged in the lower side of the lower die holder. A male die is arranged on the lower side of the upper die holder. A die shank is arranged on the upper side of the upper die holder. Connecting rods connected with the worktable in a sliding manner are symmetrically arranged in the worktable. The punching device has the advantages that a burr removing device is additionally arranged on the punching device, so that after a forge piece is punched, the burr removing device moves to remove burrs generated in punching; and since the forge piece has a certain temperature, the deformation resistance of the forge piece is relatively small, burr removing is facilitated, the service life of a cutting tool is prolonged, and the burr removing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of forging stamping devices, in particular to a stamping device for hot forging. Background technique [0002] The forging process carried out above the metal recrystallization temperature is called hot forging. Hot forging is also called hot die forging. During forging, the deformed metal flows violently, and the contact time between the forging and the mold is longer. The metal after hot forging has better properties, and the metal after hot forging often needs further processing, such as punching and other operations, which requires the use of stamping devices, but the existing stamping devices have no effect on the metal after hot forging. Clean up the burrs in time, and when the forging is cooled, the deformation resistance increases, which makes deburring very troublesome, the damage to the deburring tool is greater, and the deburring efficiency is low. Contents of the invention [0003] The purpos...
