Make platform 101 to be slidably connected.
What hydraulic press of the prior art was taken is that workbench is motionless, hydraulic jack move, therefore hydraulic jack can stretch out compared with
Grow, but two workbench can be rested on crossbeam 400, be not in the phenomenon for unloading power in hydraulic；And this programme is provided
Hydraulic press, by the position of mobile work platform, reduce the overhang of hydraulic jack, improve operating efficiency, but work as workbench
When mobile, workbench by hydraulic jack pressure when can be moved rearwards by, cause to unload power, or even hydraulic jack pushes workbench shifting
It is dynamic, it is impossible to complete press forging work, to solve this problem, slidable cushion block 500 is set in the upper surface of the first workbench 101,
After the first sliding block is acted, cushion block 500 can be slided between the workbench 101 of crossbeam 400 and first, when hydraulic press works, horizontal
Beam 400 can support the first workbench 101 by cushion block 500.
Specifically, when the first workbench 101 is as upper table, cushion block 500 is arranged on the upper table of the first workbench 101
Face；When the first workbench 101 is as lower table, cushion block 500 is arranged on the lower surface of the first workbench 101, and the purpose is to profit
It is connected, is played a supporting role with entablature 400 or sill 400 with cushion block 500.
Specifically, cushion block 500 is located on the first workbench 101, and in original state, the first workbench 101 and crossbeam 400
Between leave small gap, cushion block 500, the first workbench 101 and to cross the section after three coordinates be in " mountain " font；When first
Workbench 101 is moved in the presence of the first power source 201, after cushion block 500 is slided, cushion block 500, the first workbench 101 and horizontal stroke
Wear the section after three coordinates T-shaped.
In the alternative of the present embodiment, it is provided with the first workbench 101 for driving the second of the movement of cushion block 500 to move
Power source 501.
The slip of cushion block 500 can manually be promoted by workman, can also be energized by other power parts；We
Case on the first workbench 101 using the second power source 501 is set, and the second power source 501 drives cushion block 500 to move.
Specifically, the second power source 501 is connected by leading screw with cushion block 500, the one end of cushion block 500 is provided with feed screw nut,
The movement of cushion block 500 is driven by the cooperation of leading screw and feed screw nut, also, is provided with the first workbench 101 for cushion block 500
The chute of slip, chute is internally provided with ball or roller bearing.
Second power source 501 can also be connected by belt transmissioning mode with cushion block 500.
In the alternative of the present embodiment, the second workbench coordinated with the first workbench 101 is provided with framework 100
102, the second workbench 102 is arranged with master cylinder 600.
Second workbench 102 is set in framework 100, and the second workbench 102 coordinates with the first workbench 101, first
The upper and lower mould 802 that workpiece is placed on the workbench 102 of workbench 101 and second has, can by the cooperation of upper mould 801 and lower mould 802
Go out qualified workpiece with press forging.
Second workbench 102 is arranged with master cylinder 600, after the first workbench 101 is moved down, is arranged on the first workbench
Cushion block 500 on 101 is close from crossbeam 400 (about 1mm-5mm), and then cushion block 500 slides into the workbench of crossbeam 400 and first
Between 101, then master cylinder 600 is started working, and master cylinder 600 is arranged on the upward mould of lower mould 802 on the second workbench 102
801 are pressed, and extruding is arranged on the workpiece between mould 801 and lower mould 802.
In the alternative of the present embodiment, framework 100 is internally provided with the second guide rail coordinated with the second workbench 102
103。
When 600 pair of second workbench 102 of master cylinder applies pressure, it is necessary to which the second workbench 102 moves and drives lower mould
802 are contacted with workpiece, and workpiece is extruded；Therefore to make the second workbench 102 smoothly mobile, and the side of power is not changed
To setting the second guide rail 103 in the inside of, framework 100, the second workbench 102 is moved along the second guide rail 103, is not in
The uneven phenomenon of left and right warpage；If the second workbench 102 makes its warpage uneven because of unilateral frictional force, it can change and apply stressed
Direction, it is impossible to ensure the quality of workpiece.
In the alternative of the present embodiment, the outer wall of master cylinder 600 is wound with steel wire.
To improve the bearing capacity of master cylinder 600 and reducing the volume of master cylinder 600, it can be twined in the outer wall of master cylinder 600
Around steel wire, the intensity of master cylinder 600 can be improved using the high-tensile steel wires winding outer wall of master cylinder 600, so as to reduce master cylinder
600 wall thickness and height, makes equipment compact, reduces the height of equipment, so as to reduce requirement for height of the equipment to factory building,
Particularly flame equipment, it has requirement for height to factory building, can not be installed and used in some less factory buildings, using this
Structure can effectively reduce the height of equipment.
In the alternative of the present embodiment, hydraulic press also includes oil piping system 700, and oil piping system 700 connects with master cylinder 600
Connect.
In hydraulic press in use, needing to provide oil pressure for hydraulic press, therefore hydraulic press also includes oil piping system 700, oil circuit
System 700 is connected with master cylinder 600, by the control of controller 300, and oil piping system 700 can be supplied master cylinder 600
Oil.
In the alternative of the present embodiment, the outer wall of framework 100 is wound with steel wire.
To improve the bearing capacity of framework 100 and reducing the volume of framework 100, can in the outer wall winding steel wire of framework 100,
The intensity of framework 100 can be improved using the high-tensile steel wires winding outer wall of framework 100, so as to reduce the wall thickness and height of framework 100
Degree, makes equipment compact, reduces the height of equipment, particularly flame so as to reduce requirement for height of the equipment to factory building
Equipment, it has requirement for height to factory building, can not be installed and used in some less factory buildings, can be effective using this structure
Reduce the height of equipment.
Wherein, the pressing cycle of hydraulic press is to drive the downlink or uplink of master cylinder 600 by hydromechanical system, quick mobile
To after specified location, start to compress the inner fluid of master cylinder 600, in compression, fluid can absorb part energy in itself, only will
Fluid compression could start to suppress workpiece to a certain extent, if the amount of fluid is very big, can be wasted in pressing process
A big chunk energy, and because the amount of fluid is very big, can be time consuming in draining process.
The height of master cylinder 600 can effectively be reduced by quick moving assembly 200, it is main in using production process
The diminution of oil cylinder 600, can save the compression time of the inner fluid of master cylinder 600, the topping up time of master cylinder 600 and master cylinder
600 draining time, greatly reduce the pressing cycle of workpiece, improve operating efficiency and save the energy.
The hydraulic press that the present invention is provided, causes master cylinder 600 to reduce, and save huge using quick moving assembly 200
The liquid-filled tank of hydromechanical system and complicated replenishing valve and overhead, significantly reduces machine cost, makes height and the step reduction of machine,
And reduce the fault rate of machine；In pressing process, the workmanship to fluid can be reduced, specifically, because master cylinder 600 subtracts
It is small, fluid is reduced, when doing manual work, reduces the compression work to fluid, quickly directly workpiece can be suppressed, reduce energy
Amount is wasted；And without huge hydromechanical system, equipment cost is reduced, and device structure is simplified, simple to operate, reliability
Lifting.
Machine volume and height are reduced, huge charging line and complicated replenishing valve is save, significantly reduces machine cost.
