Abstract

The large double-acting thick plate drawing hydraulic press as one kind of hydraulic machinery consists of mainly body, platform, driving system, main cylinder, outer block edge pressing back stroke cylinder, inside block back stroke cylinder, movable bench and electric system. The movable bench consists of movable right and left benches fixed together. There are on ground oil cylinder fixing frame, connecting shaft on the frame and hinged with the ears integrally with the oil cylinder, and driving oil cylinder with piston rod connected to oil cylinder fixing frame. The main cylinder is one with double liquid filling valves, and there is block fall preventer installed onto the upper cross beam. The present invention has smooth running of the movable bench, high efficiency and other advantages.

Description

technical field [0001] The invention belongs to the technical field of hydraulic machinery, in particular to a large double-action thick plate stretching hydraulic machine. Background technique [0002] In the currently known large-scale double-action thick plate stretching hydraulic press, the mobile workbench of the large-scale press has a large table top and a heavy tonnage. The existing machine tools and lifting tools cannot complete its processing and transportation, resulting in processing, installation, and use. and maintenance difficulties. The structure of the main cylinder is to meet the rapid downward movement of the slider, and the structure of the single filling valve is selected. The structure of the filling valve is large and the height is high. The existing inner and outer sliders do not have anti-falling devices, so the purpose of anti-falling of the sliders cannot be realized. This technical defect affects the normal work and safe use of the large double-...
