Abstract
The invention discloses a structure of a novel hydraulic press. The structure consists of a hydraulic cylinder and a hydraulic system connected with the hydraulic cylinder. The structure is characterized in that: a piston of the hydraulic cylinder consists of two parts with different diameters; the piston partitions the hydraulic cylinder into three hydraulic chambers A1, A2 and A3; and by different modes of supplying oil to the three hydraulic chambers A1, A2 and A3 through the hydraulic system, the processes of fast forward, pressing, pressure maintaining, fast backward, reset and stay of the piston are realized. The structure has the advantages of simple equipment, low cost, low fault rate, low energy consumption and high efficiency.
Description
Technical field
The present invention relates to the structure of a kind of structure of hydraulic press, particularly a kind of novel hydraulic machine, belong to the hydraulic machinery technical field.
Background technique
Hydraulic press is a kind of machinery that realizes manufacturing process by pressure, in many technology occasions, needs hydraulic press to realize subordinate's work cycle, that is: F.F.-pressurization-pressurize-rewind down-reset and stopping.In order to realize above-mentioned work cycle, the hydraulic system of hydraulic press needs very big flow when fast feed, flow during pressurization is then very little, and when pressurize, flow only is the flow of internal leakage, correspondingly, on Design of Hydraulic System and structure, general low pressure and mass flow oil hydraulic pump and the high-pressure low-flow pump associating fuel feeding of adopting, under the control of control system, two oil pumps switch according to corresponding situation handover ground.The hydraulic press of this structure, owing to adopt two oil pump feeds, two cover hydraulic systems, so, there is complex structure, the defective that equipment cost and rate of fault are higher simultaneously, also exists energy loss higher, the defective that efficient is lower.
Summary of the invention
The objective of the invention is to: a kind of structure of novel hydraulic machine is provided, overcomes the existing complex structure of above-mentioned hydraulic press, equipment cost and rate of fault is higher, energy loss is higher, efficient is lower defective.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: a kind of structure of novel hydraulic machine, it is that structure by hydraulic press has an oil hydraulic cylinder, the piston of oil hydraulic cylinder is partitioned into totally three hydraulic chamber with oil hydraulic cylinder, each hydraulic chamber communicates with the oil inlet and oil return mouth, the filler opening of oil hydraulic pump is directly communicated with fuel tank by oil purifier, the circulating direction of one-way valve is consistent with oil pump oil outlet direction, and simultaneously one-way valve is connected between the filler opening of oil pump oil outlet and solenoid directional control valve, the oil outlet of solenoid directional control valve directly communicates with fuel tank, the filler opening of relief valve is connected on the oil circuit between the filler opening of one-way valve and solenoid valve, one of them oil outlet of solenoid valve is communicated with the chamber of oil hydraulic cylinder by the oil inlet and oil return mouth, the control port of pressure relay communicates with the oil circuit that is connected the oil inlet and oil return mouth, the another one oil outlet of solenoid valve communicates with the chamber of oil hydraulic cylinder by the oil inlet and oil return mouth, the control port of pressure relay communicates with the oil circuit that is connected the oil inlet and oil return mouth, the filler opening of sequence valve is communicated with the oil circuit that is connected the oil inlet and oil return mouth, the oil outlet of sequence valve links to each other with the outlet of the forward of liquid-filling valve, directly communicating with top petrol tank of liquid-filling valve by a mouthful end, the control port of liquid-filling valve communicates with the oil circuit that is connected the oil inlet and oil return mouth, and the oil inlet and oil return mouth links to each other with pipeline between sequence valve and the liquid-filling valve with pipeline.
Beneficial effect: the present invention is because after adopting such scheme, need not two oil pump feeds, two cover hydraulic systems, just can realize piston F.F.-pressurization-pressurize-rewind down-reset and stop work cycle, have that equipment is simple, cost is low, rate of fault is low, consuming little energy, advantage that efficient is high, it is higher effectively to have overcome above two oil pump feed, the existing complex structure of two cover hydraulic systems, equipment cost and fault, existing energy loss is higher, the defective that efficient is lower.
