Abstract
The utility model discloses a four-column universal hydraulic press. The four-column universal hydraulic press comprises a main unit and a hydraulic device, the main unit comprises a base and vertical columns fixedly mounted on the base, an upper beam is fixedly mounted on the upper portions of the vertical columns through vertical column nuts, a movable beam is mounted in the middles of the vertical columns through adjusting nuts, a piston cylinder with a safety device is fixed on the upper beam, the lower end of a piston rod is connected with the movable beam, an upper chamber of the piston cylinder is provided with an oil inlet hole connected with an oil pipe, and a lower chamber is provided with an overflow valve and a sequence valve. The four-column universal hydraulic press is reasonable in structure, reliable in action and long in service life, uses a hydraulic valve integrated system for hydraulic control and is applicable to processes of drawing, bending, flanging, cold extrusion, punching and the like of metal materials and further applicable to press forming of powder products, abrasive material products, plastic products and insulating materials.
Description
Technical field
The utility model relates to a kind of hydraulic press, is specifically related to a kind of four-column universal hydraulic press.
Background technology
Hydraulic press is a kind of take liquid as working media, is used for transferring energy to realize polytechnic machine.Hydraulic press also can be used for correcting, press-fits, packing, briquetting and pressing plate etc. except being used for excellent suitability for press forming.Compare with traditional Sheet Metal Forming Technology, Hydroform process in weight reduction, reduce number of spare parts and number of molds, raising rigidity and intensity, the aspect such as reduce production costs has obvious technology and economic advantages, obtained increasing application in industrial circle.Hydraulic press generally is comprised of main frame, dynamical system and hydraulic control system three parts, at present there are some shortcomings in hydraulic press, and high, the hydraulic shock of short maintenance cost in, service life not high such as hydraulic control complex operation, automaticity causes greatly the defectives such as pipeline leakage.
The utility model content
The technical problems to be solved in the utility model provides that a kind of hydraulic control is stable, the four-column hydraulic press of reliable working performance.
For solving the problems of the technologies described above, a kind of four-column universal hydraulic press of the present utility model, comprise main frame and hydraulic means, described main frame is made of support and the column that is packed on this support, described column top is fixed with entablature by upright nut, moved cross beam is equipped with by adjusting nut in the middle part of column, be fixed with the piston cylinder with safety device on the entablature, the lower end that connects the piston rod of piston cylinder is connected with moved cross beam, the epicoele of piston cylinder is provided with the fuel feed hole that links to each other with oil pipe, its cavity of resorption is provided with overflow valve and sequence valve, the prefill valve that is located at the piston cylinder top is connected with hydraulic means by oil pipe, and described hydraulic means is by distribution box, integrated package and plunger displacement pump consist of.
Compared with prior art, the beneficial effect that the utlity model has is: the utility model is rational in infrastructure, and hydraulic valve integrated system, reliable in action, long service life are adopted in hydraulic control; Hydraulic control is stable, and is easy and simple to handle, working stability, and percent defective is low, is applicable to the techniques such as stretching, bending, flange, cold-extruded, stamping-out of metal material, also is applicable to pulverulent product, abrasive product is compressing and plastic products, insulating materials compressing.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of four-column universal hydraulic press of the utility model.
The specific embodiment
As shown in Figure 1, a kind of four-column universal hydraulic press, comprise main frame and hydraulic means, described main frame is made of support and the column 8 that is packed on this support, described column 8 tops are fixed with entablature 5 by upright nut 4, moved cross beam 7 is equipped with by adjusting nut 6 in the middle part of column 8, be fixed with the piston cylinder 1 with safety device on the entablature 5, the lower end that connects the piston rod of piston cylinder 1 is connected with moved cross beam 7, the epicoele of piston cylinder 1 is provided with the fuel feed hole that links to each other with oil pipe, its cavity of resorption is provided with overflow valve and sequence valve, and the prefill valve 2 that is located at piston cylinder 1 top is connected with hydraulic means by oil pipe 3.Described hydraulic means is made of distribution box 9, integrated package 10 and plunger displacement pump 11.The utility model adopts computer optimization design, hydraulic control to adopt the hydraulic valve integrated system, reliable in action, and long service life, hydraulic shock is little, and is easy and simple to handle.
