Slider structure for three-beam and four-post hydraulic press

Abstract

The invention relates to a slider structure for a three-beam and four-post hydraulic press, which comprises a slider body. A main cylinder piston rod connecting seat is arranged at the center of the slider body, guide sleeve mounting seats are arranged at four corners of the slider body, guide sleeves are arranged in the guide sleeve mounting seats, upper flanges and lower flanges of the guide sleeves extend out of upper end faces and the lower end faces of the guide sleeve mounting seats respectively, and the extension direction of each flange is 1 / 4-1 / 3 of the thickness of each guide sleeve mounting seat. The thickness of the slider body is decreased while the length of the slider body is unchanged, so that manufacturing materials and costs are greatly saved. As an inward concave notch is arranged on a long side wall of the slider body, when the slider structure is applied to the three-beam and four-post dry powder forming hydraulic press, by the aid of the notch, a powder feeding mechanism can move forwards, the travel of a powder feeding cylinder can be shortened, powder adding efficiency is improved, front operation space is enlarged, assembly, disassembly, mould adjustment and manual takeout of products are facilitated, and safety is improved.

Description

technical field [0001] The invention relates to a hydraulic machine, in particular to a slider structure of a three-beam four-column hydraulic machine. Background technique [0002] The slider of the three-beam four-column hydraulic press is mainly used for guiding and connecting the piston rod of the main cylinder, and is driven by the piston of the main cylinder and guided by the four-column to complete the pressing and return action. The slider structure usually adopts a rectangular or square box structure with thicker beams. Generally, for a 200t three-beam and four-column hydraulic press, in order to achieve the guiding distance, the thickness of the slider reaches 400mm, which greatly increases the manufacturing cost of the slider. The three-beam four-column dry powder automatic molding hydraulic machine adopts this structure. Due to the limitation of the rectangular box structure, the powder feeding mechanism is far away from the mold cavity below the slider, which in...

The slider structure usually adopts a rectangular or square box structure with thicker beams. Generally, for a 200t three-beam and four-column hydraulic press, in order to achieve the guiding distance, the thickness of the slider reaches 400mm, which greatly increases the manufacturing cost of the slider.

The three-beam four-column dry powder automatic molding hydraulic machine adopts this structure. Due to the limitation of the rectangular box structure, the powder feeding mechanism is far away from the mold cavity under the slider, which increases the stroke of the powder feeding cylinder, and the single cycle time is long and the efficiency is low.
