Description
Technical field
The utility model relates to a kind of double action hydraulic drawing press, particularly a kind of novel double action hydraulic drawing press.Belong to technical field of forging and pressing equipment.
Background technology
Double action hydraulic drawing press is the visual plant of metal material deep stretching process, at present double action hydraulic drawing press is in the manufacturing and designing of power, the hydraulic system that all adopts two cover independent power sources to drive, realize driving respectively to master slider and blankholder slide, the double action hydraulic press of this structure is owing to need two to overlap independently hydraulic power system, so not only there is complex structure, the equipment cost problem of higher also exists the bigger defective of energy resource consumption simultaneously.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, equipment manufacturing cost is cheap, a kind of novel double action hydraulic drawing press that energy resource consumption is few.
For achieving the above object, the technical solution adopted in the utility model is: master slider adopts the hydraulic system of dynamic source type of drive, and the working method of the blankholder slide mode that piston forms back pressure when being the oil cylinder backhaul of pressured limit is carried out work.Wherein the formation of back pressure is achieved in that the back pressure hydraulic fluid port of check valve is connected with the epicoele of flanging oil cylinder with the oil-in of overflow valve and one of them outlet back in parallel of choke valve, the flanging oil cylinder is fixed on the slide block, and the piston rod of flanging oil cylinder is fixedlyed connected with blankholder slide.At above-mentioned check valve, connect with by-pass valve control in the same back in parallel of the other end hydraulic fluid port of overflow valve and choke valve hydraulic fluid port in parallel, the another port of by-pass valve control is inserted in the topping up tube of hydraulic press.In the hydraulic press both sides stroke is set and regulates push rod, when desired location is arrived in the master slider backhaul, just withstand blankholder slide, master slider then can continue backhaul to certain height, so in case push rod stops blankholder slide, then the flanging oil cylinder is under the drive of backhaul slide block, oil cylinder begins to pass through check valve, choke valve, and control valve oil suction from the topping up tube, be filled oil and work as the flanging oil cylinder, when master slider pressurizes downwards, in a single day blankholder slide touches workpiece, and then the piston rod of flanging oil cylinder has the trend of backhaul.But because the check valve of this moment oppositely can not conducting, overflow valve must pressure rise to a certain degree just can the conducting choke valve two ends produce pressure differential, so form certain back pressure in the flanging oil cylinder of this moment, and pressure reached blankholder slide, thereby play the effect of flanging.The big I of back pressure is regulated the back acquisition according to the demand of actual process accordingly to overflow valve and choke valve.
The utility model is achieved in that the main frame hydraulic power system is connected with master cylinder, be provided with towards fluid cylinder on the top of master cylinder, back pressure hydraulic fluid port one end of hydraulic control one-way valve links to each other with the epicoele of master cylinder, an other end with join towards fluid cylinder, on master slider, be provided with a flanging oil cylinder, the back pressure hydraulic fluid port of check valve and the oil-in of overflow valve and choke valve wherein a port link to each other with the flanging oil cylinder, check valve, choke valve, the other end of overflow valve links to each other with control valve, the another port of control valve with link to each other towards fluid cylinder; Position on the hydraulic press both sides is provided with two tip-lever supports respectively, simultaneously two upper ejector pins are respectively installed to two tip-lever supports above.
The utility model beneficial effect: owing to adopted such scheme, the present invention is simple in structure, and equipment manufacturing cost is cheap, and energy resource consumption is few, has effectively solved existing complex structure, and the equipment cost problem of higher has changed the bigger defective of energy resource consumption simultaneously.
