Tri-composite punching device

Abstract

The invention relates to a tri-composite punching device. The tri-composite punching device comprises a machine frame, pricker lifting air cylinders, a transverse beam, a punching mechanism, rubber press lifting air cylinders and a rubber pressing roll, wherein the machine frame comprises a left supporting plate and a right supporting plate; guide slots are respectively formed in the middle of the left supporting plate and the middle of the right supporting plate; fixed plates are respectively mounted on the outer side of the lower end of the left supporting plate and the outer side of the lower end of the right supporting plate; the transverse beam is mounted between the left supporting plate and the right supporting plate; connecting blocks are respectively arranged at upper ends of two sides of the transverse beam; after each connecting block penetrates through the corresponding guide slot, the lower end of each connecting block is connected with the upper end of the corresponding pricker lifting air cylinder; the lower end of each pricker lifting air cylinder is mounted on the corresponding fixed plate at the lower end of the left supporting plate or the right supporting plate; the punching mechanism is mounted on the lower side of the transverse beam; the rubber press lifting air cylinders are mounted on the rear side of the transverse beam. The tri-composite punching device disclosed by the invention has the advantages that the height of punch pins can be adjusted through the pricker lifting air cylinders; the left-right position of the punch pins can be adjusted through an adjusting screw rod; punched rubber can be pressed by the rubber pressing roll, so that the punch pins can be pulled out smoothly, the punch pins cannot be damaged, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to a rubber skin punching device, in particular to a three-composite punching device. Background technique [0002] In the past, the rubber skin punching was a simple punching device. The rubber skin passed under the punching roller, and the punching needle on the punching roller punched the rubber skin. However, the rubber skin sometimes needs to change the position of the hole. It is very cumbersome and time-consuming to manually remove the perforating roller, adjust it and then fix it. Moreover, the perforating needle penetrates like a rubber skin and is not easy to pull out, resulting in deformation and damage to the perforating needle. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a triple-composite punching device, which is ingenious in design, reasonable in structure, easy to use, improves work efficiency, and is safe and reliable. [0004] Technical scheme of the...
