Abstract
The utility model discloses a hydraulic drawing press which comprises a stand consisting of a lower beam and an upper beam. A movable beam is arranged between the lower beam and the upper beam. A main piston cylinder is mounted inside the upper beam and the piston rod's lower end of the main piston cylinder is connected with the movable beam. The piston inside the main piston cylinder divides the inner chamber of the oil cylinder into an upper and a lower chamber. The upper chamber is connected with a pressing plunger pump and an electrical machine through an oil pipe and a distribution box. A prefill valve and a prefill tank are arranged outside the main piston cylinder. An ejection cylinder is arranged inside the lower beam through a hydraulic cushion; adjusting nuts and bench plate are installed between the upper and the movable beams; controlling manifold blocks are arranged inside the distribution box; the upper beam is fastened by column nuts; the utility model has the advantages of being practicable, being low in cost, being convenient of use, having little hydraulic impact and extending the service life of the product.
Description
Technical field
The utility model relates to a kind of hydraulic press, particularly a kind of novel hydraulic drawing press.
Background technology
At present, the hydraulic press that uses in the production process, its hydraulic control system, it is unreliable to move, and service life is short, and hydraulic shock power is large, has increased connecting line and leakage point, dependent electric control system, PLC control, it is insensitive, unreliable to work; Regulate inconvenience, inefficiency.
The utility model content
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and a kind of novel hydraulic drawing press is provided.To achieve these goals, the utility model institute Adopts measure:
A kind of hydraulic drawing press, comprise the frame that is formed by sill and entablature, between sill and the entablature moved cross beam is installed, the main piston cylinder is installed in the described entablature, the piston-rod lower end of main piston cylinder is connected with moved cross beam, and the piston in the main piston cylinder is divided into upper and lower two chambers with cylinder cavity, and upper chamber is connected with compacting plunger displacement pump and motor by oil pipe and distribution box, the main piston cylinder is equipped with prefill valve and topping up case outward, by hydraulic die cushion liftout tank is installed in the sill;
Between described entablature and the moved cross beam adjusting nut is installed, the workbench backing plate is installed between sill and the moved cross beam;
The control integration piece is installed in the described distribution box;
Described entablature is fixed by upright nut.
The beneficial effects of the utility model: practicality, production cost is low, and is easy to use, and hydraulic shock power is little, and having prolonged product is service life.
Description of drawings
Fig. 1, planar structure schematic diagram of the present utility model.
The specific embodiment
A kind of hydraulic drawing press, comprise the frame that is formed by sill 1 and entablature 2, between sill 1 and the entablature 2 moved cross beam 3 is installed, in the described entablature 2 main piston cylinder 6 is installed, the piston-rod lower end of main piston cylinder 6 is connected with moved cross beam 3, piston in the main piston cylinder 6 is divided into upper and lower two chambers with cylinder cavity, upper chamber is connected with compacting plunger displacement pump and motor 9 by oil pipe 7 and distribution box 8, main piston cylinder 6 outer prefill valve 12 and the topping up casees 13 of being equipped with are equipped with liftout tank 13 by hydraulic die cushion 14 in the sill 1; Between described entablature 2 and the moved cross beam 3 adjusting nut 4 is installed, between sill 1 and the moved cross beam 3 workbench backing plate 5 is installed; In the described distribution box 8 control integration piece 10 is installed; Described entablature 2 is fixing by upright nut 11.
Use the time of the present utility model, be fixed with the main piston cylinder 6 with safety device in its entablature 2, the piston-rod lower end of main piston cylinder 6 is connected with moved cross beam 3, and it is connected to and is rigidly connected; Piston in the main piston cylinder 6 is divided into upper and lower two chambers with cylinder cavity; Upper chamber is provided with fuel feed hole, fuel feed hole is connected with compacting plunger displacement pump and motor 9 by oil pipe 7 and distribution box 8, lower chambers in the main piston cylinder 6 is provided with prefill valve 12, overflow valve and sequence valve, by hydraulic die cushion 14 liftout tank 13 is installed in the sill 1, in drawing process, because the pressure of main piston cylinder 6 is greater than the pressure of liftout tank 13, liftout tank 13 is forced to press down, thereby realization drawing process, the utility model mainly be applicable to metal material stretching, bending, flange, cold-extruded, stamping-out, etc. technique; Also be applicable to proofread and correct, press-fit, pulverulent product, abrasive product is compressing and plastic products, the compressing fuselage of insulating materials adopts computer optimization design, hydraulic control to adopt the hydraulic valve integrated system, reliable in action, long service life, hydraulic shock is little, has reduced connecting line and leakage point, independently electric control system, PLC control, working sensitivity is reliable.Adopt the button centralized Control, have adjustment, two kinds of modes of operation of both hands single cycle by the selection of move operation panel, can realize deciding two kinds of moulding process of journey level pressure, operating pressure, stroke can be adjustable in prescribed limit according to arts demand, thereby realize the purpose of this utility model.
Those skilled in the art's simple change and replacement in this area all are within the protection domain of the present utility model.
