Abstract
The invention discloses a hydraulic press capable of simultaneously pressing double perforating bullets. The hydraulic press comprises an upper beam, a lower beam, an upright column, a movable sliding block, a working bedplate and a pressure balancer, wherein the upright column is positioned between the upper beam and the lower beam, the movable sliding block is in sliding fit with the upright column, the movable sliding block is driven by a pressing oil cylinder arranged above the movable sliding block, the working bedplate is mounted on the lower end surface of the movable sliding block, a concave cavity is arranged in the middle of the upper end surface of the lower beam, the pressure balancer is mounted in the concave cavity, the pressure balancer comprises two plunger type cylinders communicated with each other, one plunger rod is mounted in the cylinder body of each plunger type cylinder in a matched manner, one spring is arranged between the bottom end of each plunger rod and the corresponding cylinder body, one guide sleeve is hermetically mounted at the upper end part of each plunger rod in a matched manner, each guide sleeve is fixedly mounted on the upper end surface of the cylinder body of the corresponding plunger type cylinder, and one die is mounted at the top end of each plunger rod. The hydraulic press capable of simultaneously pressing double perforating bullets has the advantages that the structural design is reasonable, the whole mechanism is compact, the space occupation is small, the production efficiency is high, the streamlined operation of perforating bullet compression molding can be realized easily, meanwhile, the working bedplate is utilized to the most extent, and the production cost is reduced.
Description
Technical field
The invention belongs to shaped by fluid pressure machinery, relate in particular to a kind of hydraulic press that can simultaneously suppress two launch hole bullets.
Background technology
The perforating bullet pressing process used at present has following defect:
1. because there is height error in Mould Machining, therefore when place when two moulds are suppressed simultaneously, can cause pressurized inhomogeneous, produce substandard products; So each working cycles press can only be suppressed a launch hole bullet, production efficiency is low, and energy loss is large.
2. pressing machinery adopts 4 column presses, and table top is larger, is no less than 600mm * 600mm, take more spaces, and effective area occupied of perforating bullet mould little (diameter is less than 100mm) causes the waste of press manufactured materials.
Summary of the invention
The objective of the invention is in order to make up the deficiency of prior art, a kind of hydraulic press that can simultaneously suppress two launch hole bullets is provided, whole mechanism compactness, take up room little, production efficiency is high, be easy to realize the streamlined operation of perforating bullet compression molding, effectively utilized again the work top of press, reduce costs simultaneously.
The present invention is achieved through the following technical solutions:
A kind of hydraulic press that can simultaneously suppress two launch hole bullets, include, sill, column, movable slider, working plate, voltage balancer, it is characterized in that: described column is positioned at, between sill, movable slider and column are slidably matched, and the compacting hydraulic oil cylinder driving by its top, described working plate is arranged on the lower surface of movable slider, the middle part, upper surface of described sill is provided with cavity, in described cavity, voltage balancer is installed, described voltage balancer includes two plunger cases that are interconnected, coordinate plunger rod is installed respectively in described plunger case cylinder body, be respectively equipped with spring between described plunger rod bottom and cylinder body, described plunger rod upper end is sealed and matched respectively guide pin bushing is installed, guide pin bushing is fixedly mounted on the plunger case cylinder upper end face, described plunger rod top is separately installed with mould.
The sealing that described plunger case cylinder body, guide pin bushing and plunger rod form by the hydrodynamic pressure force mechanism, the guide pin bushing on described two plunger cases is the integral type structure, between its inwall and plunger rod upper end outer wall, by high-pressure seal ring, seals.
Its principle is: at perforating bullet, add man-hour, at first mould is placed on two plunger rods above voltage balancer, because mold height is not identical, during the pressurization of compacting oil cylinder, working plate can first contact one of them mould, now voltage balancer plays a role, it is descending that the mould first be touched can be followed plunger rod, because voltage balancer is confined space, and inner UNICOM, therefore the another one plunger rod can rise with another mould, when being subject to movable slider, two moulds exert pressure when identical, the voltage balancer plunger rod remains on a state that balance is static, reach and regulate the poor purpose of mold height.
Advantage of the present invention is:
Reasonable in design of the present invention, whole mechanism compactness, take up room little, and production efficiency is high, is easy to realize the streamlined operation of perforating bullet compression molding, has utilized to greatest extent again the work top of press, reduces production costs simultaneously.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is voltage balancer structural representation of the present invention.
The specific embodiment
Referring to accompanying drawing, a kind of hydraulic press that can simultaneously suppress two launch hole bullets, include entablature 1, compacting oil cylinder 2, movable slider 3, working plate 4, column 5, voltage balancer 6, sill 7, be installed with compacting oil cylinder 2 on entablature 1, the piston-rod lower end of compacting oil cylinder 2 is connecting the movable slider 3 be slidably matched with column 5, movable slider 3 lower ends are connecting working plate 4, and voltage balancer 6 is installed in sill 7.
Voltage balancer includes two plunger cases that are interconnected, coordinate plunger rod 9 is installed respectively in plunger case cylinder body 11, be respectively equipped with spring 13,14 between plunger rod 9 bottoms and cylinder body, the guide pin bushing 10 that plunger rod 9 upper ends are sealed and matched respectively integral type is installed, guide pin bushing 10 is fixedly mounted on plunger case cylinder body 11 upper surfaces, and plunger rod 9 tops are separately installed with mould.The voltage balancer internal cavity is full of hydraulic oil when plunger rod 9 mediates.
During work, at first mould is placed on two plunger rods 9 above voltage balancer 6, because mold height is not identical, during 2 pressurization of compacting oil cylinder, working plate 4 can first contact one of them mould, because voltage balancer is confined space, and inner UNICOM is full of hydraulic oil, it is descending that the mould first be touched can be followed plunger rod, therefore the another one plunger rod can rise with another mould, when being subject to working plate, two moulds exert pressure when identical, the voltage balancer plunger rod remains on a state that balance is static, and the product pressurized suppressed is identical, and density is identical.
