Background technology
Existing upper cylinder half formula press normally plunger connects intermediate transverse girder, and last anvil block is installed in the below of intermediate transverse girder, and plunger drives intermediate transverse girder and last anvil block pumps, the movable part Heavy Weight, and energy consumption is high; The double-cylinder type press of existing upper cylinder half formula press has pressure classification and velocity stages function; Inner plunger connects intermediate transverse girder, and last anvil block is installed in the below of intermediate transverse girder, and inner plunger drives intermediate transverse girder and last anvil block pumps; Still there is the movable part Heavy Weight, the defective that energy consumption is high; The last anvil block of the cylinder moving type press of existing upper cylinder half formula press is installed in the lower end of cylinder barrel, and the cylinder barrel drive is gone up anvil block and pumped, and movable part is in light weight, though energy consumption is low, does not possess pressure classification and weight grading.China utility model patent Granted publication CN202065272 U " a kind of pull-down open die forging press that overlaps cylinder and adopt said cover cylinder " discloses a kind of cover cylinder that first pouring orifice and second pouring orifice are set on working cylinder; This cover cylinder is suitable for the pull-down press of cylinder formula press down; The cover cylinder of this patent has had pressure classification and velocity stages function; But the small plunger of cover cylinder is fixedly connected frame in the pull-down press, and it is inboard that forging tools is arranged on the frame upper end, and small plunger drives frame and forging tools pumps; Still there is the movable part Heavy Weight, the defective that energy consumption is high.Simultaneously, the motion parts quality of press is big, and inertia is big, and the swing when causing press work is big, and when forging speed was fast, the swing that causes was even more serious especially.
Summary of the invention
The present invention will solve existing press can not take into account the low technical problem of pressure, velocity stages and energy consumption, provides that a kind of to have pressure, velocity stages and energy consumption low, is suitable for the cover cylinder cylinder moving type press of rapid forge.
In order to solve the problems of the technologies described above, the technical scheme that the present invention takes is: a kind of cover cylinder cylinder moving type press, comprise entablature and frame, last anvil block be installed in the following anvil block on the frame workbench, movable plunger cooperates with the master cylinder tube; The master cylinder tube connects kicker cylinder, and anvil block is installed in the lower end; Non-movable piston is fixedly connected on the entablature, cooperates with the inner chamber of movable plunger; Pouring orifice II on the non-movable piston is communicated with the inner chamber of movable plunger, the shrinkage pool of the sensible master cylinder tube inner chamber of pouring orifice I bottom on the non-movable piston.
The oiling of pouring orifice II, master cylinder tube and movable plunger move simultaneously, and pressure is little, and speed is fast, and last anvil block relies on workpiece fast; Last anvil block is during near workpiece, and the pouring orifice II is closed, and the oiling of pouring orifice I has only the action of master cylinder tube, and pressure is big, and speed is slow, and last anvil block cooperates with following anvil block to be processed workpiece.The master cylinder tube of movable part, movable plunger and last anvil block are in light weight, and energy consumption is low, and inertia is little.Kicker cylinder can reset by the fast driving movable part.It is in light weight that the present invention combines existing cylinder moving type press movable part, and low power consumption and other advantages, and advantages such as the pressure classification of existing double-cylinder type press and velocity stages are specially adapted to the forging production of the higher and interval narrower material of forging temperature of resistance of deformation.
The sectional area of pouring orifice I be the pouring orifice II sectional area 1.5-10 doubly.Can effectively realize pressure classification and velocity stages.
The sectional area of pouring orifice I be the pouring orifice II sectional area 3-6 doubly.This is preferred data.
Entablature is fixedly connected frame through pull bar.
The outer surface of master cylinder tube is polyhedron-shaped, and is corresponding with the endoporus that being on the frame is polyhedron-shaped; Endoporus on the frame studs with guide plate, and the outer surface of guide plate and master cylinder tube is slidingly matched.Accurate, the stable operation of anvil block in the assurance.
Advantage of the present invention is: cooperate through entablature, non-movable piston and movable plunger; It is in light weight to combine existing cylinder moving type press movable part; Low power consumption and other advantages; And advantages such as the pressure classification of existing double-cylinder type press and velocity stages, be specially adapted to the forging production of the higher and interval narrower material of forging temperature of resistance of deformation.
The specific embodiment
Entablature 1 is fixedly connected through four pull bars 2 with frame 4 among the figure.Flange on non-movable piston 7 external diameters is through in the groove that is bolted to entablature 1 bottom surface, and the upper surface of non-movable piston 7 exceeds the last end face of entablature 1.Non-movable piston 7 is slidingly matched through the central lumen hole of sealing ring and movable plunger 8, and the external diameter of movable plunger 8 is slidingly matched through the central lumen hole of sealing ring and master cylinder tube 9.The opening of master cylinder tube 9 upwards.The outer surface of master cylinder tube 9 is the tetrahedron shape, and is corresponding, and the endoporus that is the tetrahedron shape is arranged on the frame 4, and the endoporus on the frame 4 studs with guide plate 12, and guide plate 12 is slidingly matched with the outer surface of master cylinder tube 9.The cylinder body of kicker cylinder 3 is fixedly mounted on the frame 4, and vertical cylinder bar connects the flange of master cylinder tube 9 upper ends.Last anvil block 5 is installed in the lower end on the master cylinder tube 9.Master cylinder tube 9, movable plunger 8 and non-movable piston 7 are concentric, the vertical installation.The inlet of vertical pouring orifice II 11 is in the upper surface of non-movable piston 7, and outlet is in the central lumen hole of movable plunger 8; Vertical pouring orifice I 10 is passed movable plunger 8, and inlet is in the upper surface of non-movable piston 7, and outlet is in the shrinkage pool of master cylinder tube 9 central lumen bottom.The sectional area of pouring orifice I 10 is 5 times of sectional area of pouring orifice II 11.Following anvil block 6 is installed on the frame workbench.
