Abstract
The invention discloses a dragon gate oil press with an anti-bending compensation mechanism. One or more than one same compensation hydraulic cylinder is arranged at the bottom of a working platform, an oil inlet of each compensation hydraulic cylinder is in parallel connection with an outlet portion of an electronic pressure valve, an oil inlet of the electronic pressure valve is in parallel connection with an oil inlet of a main oil cylinder and an oil outlet of a pressure source, and a pressure sensor is connected on the pressure source. The pressure sensor and the electronic pressure valve form a closed loop control relation. A working principle of the dragon gate oil press is that when load of the dragon gate oil press increases, working pressure of the main oil cylinder correspondingly increases, and therefore the load is loaded above base, deformation of the base is increased along with increasing of the load, but the pressure sensor carries out controlling for the electronic pressure valve through a control system according to the size of detected pressure, corresponding pressure oil is filled in the compensation oil cylinder through a person, and due to the fact that pressure generated by the compensation oil cylinder is opposite to the direction of the main oil cylinder, pressure bending moment of the main oil cylinder on the base offsets. Therefore, the dragon gate oil press with the anti-bending compensation mechanism can reduce the height of the whole machine, reduces material cost and is suitable for being used in a space situation with small height.
Description
Technical field
The present invention relates to a kind of hydraulic press, particularly a kind of gantry hydraulic press with bending resistance compensation mechanism belongs to the hydraulic press technical field.
Background technology
Gantry type oil press is because the span of walking beam, built-in beam and base is larger, so, in order to bear larger moment of flexure, it is higher that the effective depth of walking beam, built-in beam and base is generally also correspondingly done, so, under the operating pressure parameter that communicates, the hydraulic press of planer-type is the common hydraulic press of other uniform pressure parameter relatively, its appearance and size, especially height dimension are higher, this not only needs more manufactured materials, has increased the cost of hydraulic press, simultaneously, higher appearance and size is not suitable for using in less space situations.
Summary of the invention
The object of the invention is to: a kind of gantry hydraulic press with bending resistance compensation mechanism is provided, and it is existing to overcome existing gantry type oil press: need more manufactured materials, increased the cost of hydraulic press; Higher appearance and size is not suitable for obtaining defective in less space situations use.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: adopt pressure compensation mechanism, specifically: in the bottom of workbench compensating hydraulic cylinder identical more than or is set, the oil-in of each compensating hydraulic cylinder is connected in parallel on the export department of electron pressure valve, the oil-out of the oil-in of electron pressure valve and the oil-in of master cylinder and pressure source is in parallel, connect a kind of pressure sensor at pressure source, pressure sensor and electron pressure valve form the closed-loop control relation.
Beneficial effect: operation principle of the present invention is: when the load of gantry type oil press increases, the operating pressure of master cylinder correspondingly also increases, thereby, with load on above base, base will add aximal deformation value with the increasing of load, but, pressure sensor is according to the size of detecting pressure, by control system the electron pressure valve is controlled, compensating cylinder will lead to people's relevant pressure oil, because the compensating cylinder pressure and the master cylinder opposite direction that produce, so, offset master cylinder and acted on pressure moment of flexure on the base.So the present invention can reduce the height of complete machine, reduce the cost of material, suit to use in the less space of space situations height.
