Electric screw press lubrication protection and recovery system
Technical field
The invention belongs to the forcing press field, particularly the lubrication protection and the recovery system of the forcing press of the worm drive of the rectilinear motion and the mechanical switch that rotatablely moves.
Background technology
For electric screw press; Driving screw in the screw pair, mother nut are the critical components of equipment; Should do screw; The slide block of one moving linearly up and down again with it, the thread face will bear big specific pressure, shear stress and bending stress, and the quality of the lubrication protection that is therefore adopted is the efficient of screw pair and the key in service life.
Summary of the invention
The object of the present invention is to provide a kind of electric screw press lubrication protection and recovery system, this system can reduce the wearing and tearing of screw pair (being driving screw, mother nut), raises the efficiency and service life.
Electric screw press lubrication protection provided by the invention and recovery system is characterized in that: this system comprises protective cover, upper press cover and lower cover; Shielding cover is on the driving screw of electric screw press; The upper end of protective cover is installed on the oil seal ring of electric screw press through screw and upper press cover; The lower end of protective cover is installed in through screw and lower cover on the slide block of electric screw press, is provided with oil duct between the oil-in of slide block and the mother nut.
The present invention drills through the oilhole of mother nut through slide block top; Reach the purpose of lubricated driving screw, mother nut, guaranteed the sufficient lubrication of driving screw, mother nut like this, thus life-span of having improved driving screw and mother nut; Reduce wearing and tearing and noise, improved the efficient and the performance of complete machine.The screw of driving screw, mother nut drives slide block up and down during moving linearly in the screw pair; The lubricating oil that throws away in driving screw, the mother nut rotary course in the screw pair injects in the protective cover of scalability; Finally get back to oil return apparatus, reach the purpose of circulating lubricating.
Description of drawings
Fig. 1 .1 is the structural representation of electric screw press lubrication protection of the present invention and recovery system, and Fig. 1 .2 is the enlarged diagram of upper press cover part (I) among Fig. 1 .1, and Fig. 1 .3 is the enlarged diagram of upper press cover part (II) among Fig. 1 .1.
The specific embodiment
Below in conjunction with accompanying drawing and instance utility model is done further detailed explanation.
Shown in Fig. 1 .1, electric screw press lubrication protection and recovery system comprise protective cover 3, upper press cover 2 (shown in I among Fig. 1 .2) and lower cover 5 (shown in II among Fig. 1 .3).Protective cover 3 is enclosed within on the driving screw 4 of electric screw press, and protective cover 3 is used to prevent that fluid from splashing, and slide block 8 scalability when making rectilinear motion up and down.Be fixed on the oil seal ring 1 of electric screw press through screw and upper press cover 2 upper end, be fixed on the slide block 8 of electric screw press through screw and lower cover 5 lower end with protective cover 3 with protective cover 3.
Said system also can make it have the lubricating oil return function.With drilling through the formation oil duct between oil-in on the slide block 87 and the mother nut 6; Drive slide block 8 moving linearlies through rotatablely moving of driving screw in the screw pair 4, mother nut 6; Lubricating oil is gone up to move back and forth in screw pair (being driving screw and mother nut) and is reached lubricated purpose, and the oil of recovery is to oil-out 9.
The above is preferred embodiment of the present invention, but the present invention should be confined to this embodiment and the disclosed content of accompanying drawing.So everyly do not break away from the equivalence of accomplishing under the disclosed spirit of the present invention or revise, all fall into the scope of the present invention's protection.
