Panel stretching die component for metal stamping

Abstract

The invention discloses a panel component drawing processing mold assembly for metal stamping, which comprises a lower mold base, a liquid storage tank, an oil supply pump, a jacking base, an upper mold base and a lower mold sleeve, and the lower surface of the upper mold base is fixedly connected with a punch , the lower die set is fixed on the lower die base and the inner surface of the lower die set is contacted with a bottom plate, the edge of the lower surface of the bottom plate is fixed with a support ring plate, the side of the lower die set is provided with a ring groove, and the liquid outlet of the oil supply pump passes through The pipeline communicates with the ring groove from the inner ring surface of the supporting ring plate, and the inner wall of the lower die sleeve is provided with an oil collecting groove, the oil collecting groove is connected to the liquid storage tank through the pipeline, and the oil inlet of the oil supply pump is connected to the liquid storage tank through the pipeline. This kind of metal stamping panel parts stretching processing mold assembly uses the inner bottom surface of the lower mold sleeve as the ejection surface to increase the ejection force area to avoid deformation, and brush the side wall with lubricating oil or remove it while ejecting. The mold agent assists in demoulding while protecting the surface of the mold and the surface of the workpiece to improve the stamping quality of the product.

Description

technical field [0001] The invention relates to a die, in particular to a die assembly for drawing and processing a panel part for metal stamping, and belongs to the field of mechanical processing. Background technique [0002] Metal stamping is a process that uses punches and molds to deform or break iron, aluminum, copper and other plates and heterogeneous materials to achieve a certain shape and size. The stamping industry is an industry involving a wide range of fields, and it goes deep into all aspects of the manufacturing industry. In foreign countries, stamping is called sheet metal forming. Panel products are one of the more complicated surface shapes in sheet metal stamping parts. In the drawing process, the deformation of the blank is complicated. The shear stress on the side wall can easily induce deformation and fracture, and after stamping and forming, it is easy to get stuck in the lower mold sleeve when demolding. The traditional operation uses the ejector me...

Problems solved by technology

Panel products are one of the more complicated surface shapes in sheet metal stamping parts. In the drawing process, the deformation of the blank is complicated. The shear stress on the side wall can easily induce deformation and fracture, and after stamping and forming, it is easy to get stuck in the lower mold sleeve when demolding. The traditional operation uses the ejector method to eject the bottom surface of the molded product, which is easy to cause deformation for thin plate parts , so we propose a metal stamping panel drawing processing die assembly
