Abstract
The invention relates to a jacking cylinder of a press machine travelling worktable. The jacking cylinder comprises an in-die-area jacking cylinder and an out-of-die-area jacking cylinder, the in-die-area jacking cylinder comprises a cylinder body A and a piston A slidably mounted in an inner wall of the cylinder body A, and the out-of-die-area jacking cylinder comprises a cylinder body B and a piston B slidably mounted in an inner wall of the cylinder body B. Pressure oil is fed into a lower chamber A of the in-die-area jacking cylinder via a lower chamber oil inlet, and the piston A drives a guide rail to move upwards in the cylinder body A, so that a jacking function of the travelling worktable is achieved, and leaked oil of an upper chamber A returns via an oil return port. When the travelling worktable drops down, the pressure oil is not fed into the lower chamber A any longer, a dropping function is achieved by the aid of self weight of the travelling worktable, and the oil of the lower chamber A returns via the lower chamber oil inlet A. Pressure oil is fed into a lower chamber B of the out-of-die-area jacking cylinder via a lower chamber oil inlet B, and the piston B drives a guide rail B, a gland and a stopper to move upwards in the cylinder body B, so that the jacking function of the travelling worktable is achieved.
Description
Technical field
The present invention relates to a kind of press machine component, be specifically related to a kind of oil cylinder.
Background technique
Before press machine was started working, shuttle table drove into and puts in place, fell, and this moment, wheel soared, and the mobile working stage body contacts with base, and binding clasp clamps shuttle table then, and press machine is started working.More during mold exchange, the jack-up cylinder is with shuttle table jack-up in the mould district, if T type shuttle table after shuttle table is left the mould district, needs commutation, the outer jack-up cylinder in mould district this moment falls, and the shuttle table wheel commutates, and shuttle table is left and put in place.
Because the narrow limitation of processing and mounting technology, traditional jack-up cylinder adopt semi-closed structure leakage of oil problem in use very serious, install also inconvenient.A series of other problems that leakage of oil also causes easily, too short working life as the pumping plant element, shuttle table jack-up overlong time, jack-up fall instability etc.The piston length of existing jack-up oil cylinder is 72mm, and piston length is short little with the inboard wall of cylinder block area of contact, causes piston guide bad, the stability that influenced jack-up oil cylinder jack-up, falls.
Summary of the invention
The present invention provides a kind of moveable platform of press jack-up oil cylinder in order to overcome the deficiency of above technology.
The present invention overcomes the technological scheme that its technical problem adopts:
