Abstract
The utility model provides a moveable workbench driving moving device for a hydraulic press, which comprises a moveable workbench, a bracket, a chain wheel, chains, a hydraulic motor and a box body. One end of the box body is fixed with a driven wheel through a shaft and the other end is connected with the hydraulic motor through a key; a driving wheel is sleeved on a shaft of the hydraulic motor; the chains are hitched on the driving wheel and the driven wheel; and the moveable workbench is supported on the bracket whose bottom is fixed on a chain buckle. The moveable workbench driving device adopts the hydraulic motor and makes use of an adjustable hydraulic oil passage to control the moveable workbench, so that when the moveable workbench restores, the chains or other elements can not be damaged due to inertia of the power source. Meanwhile, an overflow pipe is arranged at an overflow port of the hydraulic motor, so automatic flooding can be realized.
Description
Technical field
The utility model relates to hydraulic press, is specifically related to a kind of actuator of movable workbench of hydraulic press.
Background technology
The actuator of movable workbench of hydraulic press in the market is with the reductor source that is used as power.This shortcoming is: when workbench reset to the dead point, because the effect of inertia of reductor, chain or miscellaneous part damaged when regular meeting.Also useful in addition cross cylinder realizes dragging travelling table, but only at less work top, has significant limitation.
The utility model content
In order to solve above technical problem, the actuator of a kind of movable workbench of hydraulic press of the present utility model, constitute by travelling table, support, sprocket wheel, chain, hydraulic motor, casing, its innovative point is: an end of described casing passes through fixedly driven pulley of axle, the other end of casing is connected with the hydraulic motor key, driving wheel is enclosed within on the axle of hydraulic motor, is with chain on driving wheel and driven pulley; Described travelling table is bearing on the support, and the bottom of support is fixed on chain and buckles.
Have on the described hydraulic motor and just change oil-in, counter-rotating oil-in and overfall, the pipeline of hydraulic oil container is communicated to respectively by total oil pump, gross pressure valve is just changeing oil-in, counter-rotating oil-in, and just change oil inlet pipe and the pipeline of the oil inlet pipe that reverses on be connected overflow valve and speed-regulating valve respectively; Connecting pipe on the overfall of described hydraulic motor is communicated with fuel tank.
The advantage of above structure is: the actuator of travelling table adopts hydraulic motor, by of the control of adjustable hydraulic circuit to travelling table, make when travelling table resets, can not make chain or other component wear because of the inertia of power source, and the overfall place at hydraulic motor leaves overflow pipe, can realize automatic overflow.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a side view of the present utility model;
Fig. 3 is an oil circuit schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1, 2, 3, each fixes a static housing 2 in the both sides of travelling table 1, and by the fixing driven pulley 4 of axle 3, the other end of casing 2 is connected with hydraulic motor 5 keys at an end of casing 2, driving wheel 6 is enclosed within on the axle 7 of hydraulic motor, is with chain on driving wheel 6 and driven pulley 4.Travelling table 1 is bearing on the support 8, and the bottom of support 8 is fixed on the clasp of chain 9.
Have on the above-mentioned hydraulic motor 5 and just change oil-in 10, counter-rotating oil-in 11 and overfall 12, it is as follows that it connects oil circuit: the pipeline 14 of hydraulic oil container 13 is communicated to respectively by total oil pump 15, gross pressure valve 16 is just changeing oil-in 10, counter-rotating oil-in 11, and on the pipeline that just changes oil inlet pipe 17 and counter-rotating oil inlet pipe 18, is connected respectively just changeing overflow valve 19, reverse overflow valve 20 and main story speed-regulating valve 21, anti-pass speed-regulating valve 22, and on overfall 12 connecting pipe 23, be communicated with fuel tank 13, realize automatic overflow.
During work, open total oil pump 15 and gross pressure valve 16, adjust the running of oil circuit by just changeing overflow valve 19, counter-rotating overflow valve 20 and main story speed-regulating valve 21,22 4 valves of anti-pass speed-regulating valve, pressure, speed can be adjusted as requested, reach not superpressure, the former thereby damage of chain or miscellaneous part so just can not occur because of power.
Claims (2)
1, a kind of actuator of movable workbench of hydraulic press, constitute by travelling table, support, sprocket wheel, chain, hydraulic motor, casing, it is characterized in that: an end of described casing passes through fixedly driven pulley of axle, the other end of casing is connected with the hydraulic motor key, driving wheel is enclosed within on the axle of hydraulic motor, is with chain on driving wheel and driven pulley; Described travelling table is bearing on the support, and the bottom of support is fixed on chain and buckles.
2, the actuator of a kind of movable workbench of hydraulic press according to claim 1, it is characterized in that: having on the described hydraulic motor just changes oil-in, counter-rotating oil-in and overfall, the pipeline of hydraulic oil container is communicated to respectively by total oil pump, gross pressure valve is just changeing oil-in, counter-rotating oil-in, and just change oil inlet pipe and the pipeline of the oil inlet pipe that reverses on be connected overflow valve and speed-regulating valve respectively; Connecting pipe on the overfall of described hydraulic motor is communicated with fuel tank.
