Abstract

The utility model relates to a controller with high precision for a powder article hydraulic machine. The utility model is characterized in that after fixedly fixed with a movable beam and a work bench, an upper and a lower main cylinders are respectively connected with a left and a right proportion throttle valves, and a left and a right proportion pumps respectively through an upper and a lower reversing valves; the movable beam and the lower main cylinder are also provided with an upper and a lower racks meshed with an upper and a lower gears which are respectively provided with an upper and a lower circular gratings connected with an upper-position and a lower-position displays. The upper-position and the lower-position displays are respectively connected with the upper and the lower reversing valves, and the left and the right proportion throttle valves. The utility model can press a part with a guide angle of any direction, which causes the upper and the lower main cylinders to have high compaction, capacity determination and powder feeding precision.

Description

Be used for the high accuracy control device on the hydraulic press for powder products
The utility model relates to a kind of high accuracy control device that is used on the hydraulic press for powder products.
The constant volume of present known hydraulic press for powder products dress powder is by mechanical position limitation, and matches with electric switch and to finish.Because itself structure is limit, therefore this structure can only be suppressed some simply not with the part of lead angle, and can not suppress the part that has negative lead angle, its reason is that finish by mechanical position limitation its constant volume dress powder position, counterdie just can not have the action of rising once more after then adorning powder, otherwise the powder of compacting will overflow, and constant volume dress pruinescence destroys.
The purpose of this utility model be to overcome the deficiency in the known technology and the part that provides a kind of energy can suppress to have negative lead angle by the operation control of self be used for high accuracy control device on the hydraulic press for powder products.
The purpose of this utility model is achieved in that
The plunger rod of going up master cylinder in the utility model is installed in moving beam, last master cylinder even is equipped with right proportional throttle valve by last reversal valve, right proportional throttle valve even is equipped with right proportioning pump, right proportioning pump is equipped with left proportioning pump except that connecting to adorn also to connect the motor, left side proportioning pump connects adorns left proportional throttle valve, left side proportional throttle valve even loads master cylinder by following reversal valve, following master cylinder is installed in workbench, on the plunger rod of the above-mentioned upper and lower master cylinder of moving beam, be fixed with respectively, following tooth bar, to go up, lower gear all is installed in workbench and meshes respectively, following tooth bar, last, be fixed with respectively on the lower gear, round down grating, last circle grating even is loaded on position indicator, last position indicator also connects respectively and is loaded on reversal valve and right proportional throttle valve, round down grating connects and is loaded on the upper/lower positions display, and the upper/lower positions display also connects respectively and is loaded on down reversal valve and left proportional throttle valve.
The utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
The plunger rod 9 of last master cylinder 8 is packed on the moving beam 10, on moving beam, be fixed with upper rack 11,13 be packed on the workbench (not shown) with intermeshing the cogging of upper rack, be fixed with circle grating 12 on cogging, upward round grating is connected with last position indicator 14.Above-mentioned last master cylinder is connected with right proportional throttle valve 4 by last reversal valve 7, right proportional throttle valve is connected with right proportioning pump 2 again, right proportioning pump also is connected with left proportioning pump 3 with motor 1 respectively, left side proportioning pump is connected with left proportional throttle valve 5, left side proportional throttle valve also is connected with following reversal valve 6, following reversal valve is connected with following master cylinder 20 again, following master cylinder is packed in the workbench (not shown), on the plunger rod 19 of following master cylinder, will descend tooth bar 18 to install on it, to also be packed on the workbench with the intermeshing lower gear 7 of following tooth bar, be fixed with circle grating 16 down on lower gear, following circle grating is connected with upper/lower positions display 15.Connect and be connected to left and right proportional throttle valve again after above-mentioned upper and lower position display also all connects upper and lower reversal valve respectively.
What the utility model adopted that two left and right proportioning pumps and two left and right proportional throttle valves control the operating rate of compacted part of master cylinder and following master cylinder respectively ejects, returns speed.The size terminal point of setting near hydraulic press in the compacting of last master cylinder and down master cylinder eject constant volume dress powder by near during to setting size terminal point, detecting the back by the upper and lower position display instructs, left and right proportional throttle valve by the band feedback changes the descending output flow of left and right proportioning pump rapidly again, approach terminal point with jogging speed with the very short time, the that time of reaching home, the flow of left and right proportioning pump is cut off fully, and the result is not reruned upper and lower master cylinder.The utility model compacting precision and constant volume dress powder precision reach 0.01 millimeter.
