Description
Technical field
The utility model relates to a kind of closed height adjusting device of forcing press, is particularly useful for a kind of closed height adjusting device of fine blanking hydraulic press.
Background technology
The closed height of fine blanking hydraulic press is regulated the top dead-centre repeatable accuracy control that just is meant equipment.Circulation of the every operation of equipment, slide block promptly by a top dead-centre, are gone out a workpiece.In the moment that mould is finished the stamping-out action, because the effect of inertia force, slide block also will continue operation, have an effect up to stopping means.Therefore factors such as the version of slide block inertia force size, stopping means, rigidity size, contact gap exert an influence all can for slide block upper dead center position precision.
Whether superior, the degree of regulation of closed height is very important performance indications, and is especially most important for fine blanking hydraulic press (hereinafter to be referred as smart impact machine) if estimating forging equipment.Since fine blanking die protruding, the die gap is very little (is generally 0.01～0.03mm), so when smart impact machine is worked, the accurate closed height of control appliance (generally should be controlled in the 0.02mm), making to allow workpiece separate with raw material, can not allow punch to enter die again, damage to cause die point.
Closed height adjusting device of the prior art, complex structure, degree of regulation are low, are difficult to satisfy the required precision of smart impact machine to closed height.
The utility model content
The purpose of this utility model provides a kind of closed height adjusting device of fine blanking hydraulic press, and this apparatus structure is simple, degree of regulation is high, can satisfy the required precision of smart impact machine to closed height.
The purpose of this utility model is achieved through the following technical solutions:
The closed height adjusting device of fine blanking hydraulic press of the present utility model, described fine blanking hydraulic press comprises master cylinder and main plunger, described closed height adjusting device comprises moving nut and quiet nut, described quiet nut is loaded on described master cylinder lower end, described moving nut sleeve is on described main plunger, be meshing with each other by screw thread pair between the inwall of described quiet nut and the outer wall of described moving nut, described moving nut is connected with rotating driving device.
The technical scheme that is provided by above-mentioned the utility model as can be seen, the closed height adjusting device of fine blanking hydraulic press described in the utility model, owing to comprise moving nut and quiet nut, quiet nut is loaded on the master cylinder lower end, moving nut sleeve is on main plunger, be meshing with each other by screw thread pair between the inwall of quiet nut and the outer wall of moving nut, moving nut is connected with rotating driving device.By a pair of relative motion that is threaded secondary nut, make the master cylinder of smart impact machine and main plunger produce relative displacement, thereby realize the adjusting of closed height.Simple in structure, degree of regulation is high, can satisfy the required precision of smart impact machine to closed height.
Description of drawings
Fig. 1 is the structure diagram of the closed height adjusting device of fine blanking hydraulic press of the present utility model.
Among the figure: 11. stepper motors, 12. transmission devices, 13. master cylinders, 14. quiet nuts, 15. moving nuts, 16. locking cylinders, 17. stop nut flanges, 18. main plungers.
The specific embodiment
The closed height adjusting device of fine blanking hydraulic press of the present utility model, its preferable specific embodiment is:
Described fine blanking hydraulic press comprises master cylinder and main plunger, described closed height adjusting device comprises moving nut and quiet nut, described quiet nut is loaded on described master cylinder lower end, described moving nut sleeve is on described main plunger, be meshing with each other by screw thread pair between the inwall of described quiet nut and the outer wall of described moving nut, described moving nut is connected with rotating driving device.
Can be provided with locking device between described quiet nut and the described moving nut.
Described locking device comprises the stop nut on the external screw thread that is engaged in described moving nut, and described stop nut is provided with the stop nut flange, is provided with locking cylinder between described stop nut flange and the described quiet nut.Also can adopt other locking device.
Described rotating driving device can comprise transmission device, stepper motor.
Closed height adjusting device of the present utility model, by stepper motor, when the moving nut of actuator drives rotates, its quiet relatively nut (master cylinder) is moved up and down, distance between moving nut lower surface and the main plunger annular upper end face, determine the last line displacement size of main plunger, also promptly determined the slide block closed height.After each adjusting action is finished, pass to hydraulic oil to locking cylinder, make the plunger piston locking in the locking cylinder hold out against the stop nut flange all the time, thereby make the screw thread pair of nut be pressed against the same side all the time, and then force to eliminate the screw thread pair gap, make the closed height adjusting of equipment have very high precision.Structure is simple relatively, degree of regulation is high, and has the function of forcing to eliminate the screw thread pair gap, is the very high closed height adjusting device of a kind of precision, can satisfy the requirement of smart impact machine to closed height.
Also the utility model is described in further detail in conjunction with the accompanying drawings below by specific embodiment:
As shown in Figure 1, quiet nut 14 places master cylinder 13 lower ends, when smart impact machine need be regulated closed height, start stepper motor 11, drive moving nut 15 by transmission device 12 and move up and down, the distance between moving nut 15 lower surfaces and the main plunger 18 annular upper end faces is exactly the closed height of equipment.When moving nut 15 up moved to a certain position and stops, the climb of main plunger 18 increased, and the closed height of equipment reduces; When moving nut 15 down moved to a certain position and stops, the climb of main plunger 18 reduced, and the shut height of equipment increases.
This device at quiet nut 14 along Zhou Zengshe locking cylinder 16, after each adjusting action is finished, in locking cylinder 16, pass to hydraulic oil, make the plunger piston locking in the locking cylinder 16 hold out against stop nut flange 17 all the time, thereby make the screw thread pair of nut be pressed against the same side all the time, force to eliminate the screw thread pair gap, guarantee the degree of regulation of closed height.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
