The invention relates to an air cushion of a novel two-way press machine; two air cushion guide sleeves are symmetrically arranged on top plates; a guide pillar which is the same as that of the lower top plate is arranged on the upper top plate; the guide pillars are respectively arranged in the air cushion guide sleeves; the upper end and the lower end of a double-air bag are respectively sealed by an upper cover plate and a lower cover plate; a specific air bag is arranged between the upper top plate and the lower top plate; pressure compressed air is filled into the double-air bag; the double-air bag is connected between the upper top plate and the lower top plate; the lower top plate is connected with a middle plate; and the middle plate is fixed with the guide pillars by guide pillar pins.
Description
technical field [0001] The invention relates to a two-way press air cushion, in particular to a novel two-way press air cushion, which belongs to the technical field of forging machinery. Background technique [0002] The air cushion is an important functional part of the press. It plays the role of pressing and returning the workpiece in the stretching operation, and plays the role of withdrawing the workpiece in the blanking operation; at present, the air cushion of the press is not only complicated in structure, but also processing The manufacturing process is complicated, and it is easy to cause the air cushion of the press to wear quickly, the material to be pressed is slow to start, and the return work is not fast. Contents of the invention [0003] The purpose of the present invention is to provide a new type of two-way press air cushion, which overcomes the defects of the existing press air cushion, such as fast wear of the press air cushion, slow starting of the p...
