Abstract

The invention relates to a top dead center buffer air cushion. The top dead center buffer air cushion includes a piston air cylinder system, a multi-stage buffer system, a pressure adjustment system and a cam protection system; the piston air cylinder system includes a cylinder body, a piston rod, a piston and a venting plate; the multi-stage buffer system includes a multi-layer orifice plate anda baffle; the pressure adjustment system includes an adjustment block, an adjustment spring and an adjustment rod; the cam protection system includes a connecting rod and a cam rack. The top dead center buffer air cushion has the advantages of adopting multi-stage buffering and being good in buffering effect, convenient to adjust, stable in structure and long in service life.

Description

technical field [0001] The patent of the present invention relates to the air cushion part of a large press, in particular to a cushioning air cushion. Background technique [0002] A press is a device used for stamping in the field of mechanical manufacturing. The air cushion part of most large presses has no top dead center cushioning device now. Even if some also use polyurethane buffer, its top dead center transition is unstable, and its lifespan is also low, so it needs to be replaced frequently. In addition, large presses without some buffer devices also have personal safety issues, and accidents may occur. Therefore, a safe and reliable cushioning air cushion is a necessary choice. [0003] Therefore, how to design a top dead center cushioning air cushion to overcome the above-mentioned existing problems is a problem to be solved urgently by those skilled in the art. Contents of the invention [0004] The main purpose of the present invention is to provide a top...
