Punching belt rubber piece device capable of realizing automatic material returning

Abstract

The invention relates to a punching belt rubber piece device capable of realizing automatic material returning. The punching belt rubber piece device comprises an upper mold and a lower mold, wherein the lower end surface of the upper mold is provided with an upper die cavity, the upper end surface of the lower mold is provided with a lower die cavity, after the upper mold and the lower mold are combined, the upper die cavity and the lower die cavity are combined into a complete die cavity, an ascending and descending mechanism is arranged at the lower end surface of the lower mold, the lower end of the ascending and descending mechanism is fixedly arranged on a base, at least two support rods are arranged on the base, the upper ends of the two support rods are respectively arranged on the upper mold, an automatic material returning device is arranged on the lower mold, the automatic material returning device comprises an air supply device arranged on the base, a material jacking hole is formed in the lower mold and is communicated with the lower die cavity of the lower mold, the air supply end of the air supply device is arranged in the material jacking hole, after the punching process is completed, the air supply device is started, and the air supply end of the air supply device conveys high-pressure air into the material jacking hole, so rubber pieces in the lower die cavity are ejected out from the lower die cavity through high-pressure air, the problem of difficult manual material discharging is solved, and the work efficiency is improved.

Description

technical field [0001] The invention relates to a stamping die, in particular to a stamping belt film device capable of automatically returning materials. Background technique [0002] At present, the materials of idler rollers and surface-increasing rollers used in domestic belt transportation equipment are made of steel pipes, glue on the surface of steel pipes, chemical materials and ceramic materials. Among them, glue on the surface of steel rollers is the most commonly used. In order to enhance the wear resistance of glue, Therefore, the glue on the surface of the steel roller needs to be punched and formed on the surface of the steel roller. After the stamping is completed, due to the high punching force, the film is easily stuck in the mold cavity. When removing the film, other tools are needed, which is inconvenient to operate. And work efficiency is low. Contents of the invention [0003] In view of the above technical problems, the present invention provides a s...
