Description

A kind of pressure machine closed height adjusting device and control system thereof
Technical field
The present invention relates to a kind of closed height adjusting device and control system thereof, particularly a kind of pressure machine closed height adjusting device and control system thereof belong to the metal forming machinery technical field.
Background technology
For the ease of install, change, the maintenance mould, and for aborning to crossing the isoparametric adjusting of modulus, all be provided with the closed height governor motion in the sliding-block linkage of forcing press.At present, the closed height governor motion all adopts mechanically operated method to carry out, and this control method is complex structure not only, and manufacture difficulty is bigger, regulates comparatively trouble, also has the higher defective of fault rate simultaneously.
Summary of the invention
The objective of the invention is to: a kind of pressure machine closed height adjusting device and control system thereof are provided, overcome existing closed height governor motion owing to adopt mechanically operated mode, the complex structure that is brought, manufacture difficulty is bigger, regulate comparatively trouble, also have the higher defective of fault rate simultaneously.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of pressure machine closed height adjusting device and control system thereof, it is made up of fuel tank, oil filter, oil pump, main line overflow valve, two-bit triplet magnetic valve, following cylinder safety valve, following cylinder hydraulic control one-way valve, upper cylinder half hydraulic control one-way valve, upper cylinder half safety valve, hydraulic cylinder, slide block, connecting rod, bent axle.Described hydraulic cylinder and slide block can be the version of disjunctor, also can be the version of split, and an end of the piston rod of hydraulic cylinder and connecting rod is hinged, and an other end of connecting rod links to each other by suitable mode with bent axle.At the oil inlet and outlet position of hydraulic cylinder epicoele, link to each other with upper cylinder half hydraulic control one-way valve, upper cylinder half safety valve respectively with three-way connection, the installation of upper cylinder half hydraulic control one-way valve and upper cylinder half safety valve and the oil cylinder of its UNICOM can form the back pressure relation; Oil inlet and outlet position at the hydraulic cylinder cavity of resorption, link to each other with following cylinder hydraulic control one-way valve, following cylinder safety valve respectively with three-way connection, following cylinder hydraulic control one-way valve can form the back pressure relation with the installation of following cylinder safety valve and the oil cylinder of its UNICOM, and the upper cylinder half safety valve is directly linked to each other with fuel tank with the outlet of following cylinder safety valve.The control oil circuit of upper cylinder half hydraulic control one-way valve is connected with the oil-in of following cylinder hydraulic control one-way valve, the control oil circuit of following cylinder hydraulic control one-way valve is connected with the oil-in of upper cylinder half hydraulic control one-way valve, following cylinder hydraulic control one-way valve is linked to each other with two oil-outs of two-bit triplet magnetic valve respectively with the oil-in of upper cylinder half hydraulic control one-way valve, the oil return opening of two-bit triplet magnetic valve is directly communicated with fuel tank, with three-way connection respectively with the oil-in of two-bit triplet magnetic valve, the oil-out of oil pump and main line overflow valve link to each other, the oil-out of main line overflow valve directly communicates with fuel tank, communicates with fuel tank behind the oil-out process oil filter with oil pump.
Operation principle of the present invention is: the hydraulic oil that oil pump is got, under the control of two-bit triplet magnetic valve, can enter in the upper and lower cavity of oil cylinder through upper cylinder half hydraulic control one-way valve and following cylinder hydraulic control one-way valve respectively, because the piston rod of oil cylinder and rod hinge connection are together, connecting rod is connected with bent axle again, there is not the free degree at above-below direction, hydraulic cylinder and slide block fix, so, slide block is motion up or down just, after slide block was adjusted to suitable position, the two-bit triplet magnetic valve quit work, so the upper cylinder half hydraulic control one-way valve is in closing state with following cylinder hydraulic control one-way valve, and the upper cylinder half safety valve will just can be opened by certain pressure with opening of following cylinder safety valve, so the hydraulic fluid port up and down of hydraulic cylinder is in closed condition at this moment, to utilize the carrying out of operate as normal; In case hinder with corresponding when the pressure load of forcing press or slide block are regulated downwards, all can cause the cavity of resorption or the pressure anomaly in the epicoele of oil cylinder to raise, so, corresponding safety valve is opened pressure release, thereby play safe effect, the main line overflow valve rises in system and guarantees that main line oil is no more than specified parameter.
Beneficial effect the present invention is owing to be provided with hydraulic cylinder on slide block, adopt hydraulic way that slide block is regulated, so have simple in structure, easy to manufacture, it is comparatively convenient to regulate, the advantage that the simultaneous faults rate is also lower, in addition, because hydraulic system when quitting work, is set up certain back pressure, so can play effective safety effect in the upper and lower cavity of hydraulic cylinder.
