[CN 201611076373.2] Hot extrusion forming hydraulic press
[CN 201611076373.2] Title of a hot extrusion forming hydraulic press: Application number of a hot extrusion forming hydraulic press: CN 201611076373.2 Applicant: Nantong Guoyi Forging Machine Tool Co., Ltd. Application date: 2016-11-30 Patent type: Invention application The present invention relates to a hot extrusion forming hydraulic press, which is characterized in that it includes a main oil cylinder, an upper beam, an upper slider, a column, a working chamber, an auxiliary workbench, a lower slider, a workbench, a top cylinder and a base; by adopting a protective box, inert gas is filled in the protective box, so that flammable and explosive raw material powder is safer and more reliable during compression molding. The leakage of inert gas is reduced by setting a gas leakage prevention buffer zone on the outside of the protective box and a corrugated pipe on the outside of the joint with the protective box. A product stacking table and a product preheating table are arranged in the protection. The product raw materials are preheated and then extruded, then the product eliminates the internal stress of the product through the residual temperature, reduces the internal stress of the product, and improves the quality and service life of the product.
