Abstract
The utility model relates to a double clutch driving friction press, belonging to the friction press power driving technical field; the end part of a screw rod is provided with two flywheels with opposite rotating direction and is simultaneously provided with two friction clutches corresponding to the two flywheels; corresponding to that the friction clutches are connected or disconnected with the screw rod, a friction wheel is driven to rotate with the flywheel by the corresponding flywheel, and thereby, the top and bottom movement of a sliding block can be realized.
Description
The utility model relates to a kind of power drive mechanism of friction press, belongs to friction press power drive system technical field.
At present, at home and abroad in the power drive system of friction press, mainly contain two kinds of forms, a kind of is screw mandrel positive and negative rotation in the Fixed Nut of friction press fuselage, thereby realize moving up and down of screw mandrel, and moving up and down by screw mandrel, driving operating mechanism's slide block moves up and down, a flywheel that is fixedly connected with screw mandrel is installed at the top of this press screw rod, install two in two sides of flywheel and be in same friction pulley above the power transmission shaft, two friction pulleys are owing to be contained on the same power transmission shaft, thereby rotating speed with turn to all identical, the axis of rotation square crossing of friction pulley and flywheel, the contact situation of the friction pulley by control flywheel two sides, realize the flywheel rotating, thereby realize moving up and down of operating mechanism's slide block.Alternative power drive system is to realize like this, screw mandrel is contained in the free degree that has rotation on the fuselage, but less than the free degree that moves up and down along screw mandrel, in the bottom of screw mandrel operating mechanism's slide block is housed, because being the internal and external threads by separately, slide block and screw mandrel cooperate, thereby when the screw mandrel rotating, slide block is just with respect to screw mandrel motion up and down.At the top of this screw mandrel one flywheel and clutch are installed, do dry run at flywheel at ordinary times in the screw axis end, clutch is in case after connecting, flywheel just drives screw mandrel and flywheel rotates with unequal angular velocity by same direction, because flywheel is by same direction rotation, thereby, also can only be by the screw mandrel that flywheel drove by same direction rotation, promptly by making the downward direction of action rotation of slide block, during the slide block backhaul, the hydraulic cylinder (or cylinder) that is installed in fuselage two sides is moving to pushing back with slide block, thereby realizes the backhaul of slide block.When the slide block backhaul, this moment throw-out-of clutch, mutually noninterfere between screw mandrel and the flywheel.Because the screw thread of screw mandrel does not have self-lock ability with the screw thread above the slide block on cooperating, screw mandrel reverses under the effect of axial force, thereby slide block is risen.By two kinds of press structure situations of above-mentioned narration, main shortcoming below main the existence: first kind of described friction press because the contact area between flywheel and the friction pulley is less, has big slip relatively simultaneously, thereby wearing and tearing are bigger, simultaneously, because that screw mandrel reaches regulation rotating speed is must the time also longer, the slide block blow energy is low, energy consumption is also bigger, by said structure as can be known, it is not compact that the friction press of this structure also exists structure, the shortcoming that volume is bigger.Above-mentioned described second kind of friction press, though clutch can instantaneous combination, it is must a rotating speed acceleration time short that screw mandrel reaches institute, and the slide block blow energy is big, but slide block must retract (or pushing up back) with it with oil cylinder (or cylinder) when backhaul, thereby structure is complicated, and the backhaul of slide block simultaneously is also slower, and, because when slide block is risen by the external force effect, side at the screw mandrel screw thread is also upwarded pressure, thereby the screw mandrel abrasion is also comparatively serious, and the life-span of screw mandrel is reduced.
The purpose of this utility model is to provide a kind of higher blow energy that has, and the slide block backhaul is very fast, and screw mandrel is not easy to wear, has the new-type friction press of compact conformation simultaneously.
For achieving the above object, the utility model is provided with two opposite flywheels of direction of rotation at the top of screw mandrel, and the clutch that matches mutually with two flywheels, corresponding clutch engages or throws off, screw mandrel is just under the drive of flywheel, identical with above-mentioned corresponding flywheel turn to and angular speed rotates, screw mandrel partly screw thread down just can spinning in and out in the internal thread of slide block, thereby the slide block realization is moved up and down.
The utility model since the opposite flywheel of two direction of rotation is set at the top of screw mandrel and with the corresponding friction clutch of two flywheels, corresponding clutch is once the connection screw mandrel just can be by same direction of flywheel and unequal angular velocity rotation, it is shorter that screw mandrel reaches desired rotating speed institute's palpus acceleration time, thereby the quick return that makes slide block have higher blow energy and realize slide block, because above-mentioned structure makes that also the structure of friction press is compact, volume is little, and the situation of screw mandrel screw thread wearing and tearing is also alleviated.
Accompanying drawing is a schematic diagram of the present utility model, and shown in the figure: 1-rotates inlet suction port, and 2-rotates inlet suction port, the 3-bearing, 4-bearing, 5-flywheel, the 6-clutch plunger, 7-clutch cylinder, 8-bearing, 9-flywheel, 10-close the device piston, the 11-clutch cylinder, the 12-screw mandrel, 13-fuselage, 14-slide block, the 15-support, 16-key, 17-key.
Below in conjunction with accompanying drawing the utility model is further described.Screw mandrel 12 expressions shown in the figure have only the free degree of rotating vertically and the free degree that does not move up and down, thereby the rotating of screw mandrel just can drive operating mechanism's slide block 14 and moves up and down, reach the purpose that makes friction press work, and the different rotary direction of screw mandrel 12 is achieved in that if rotation inlet suction port 1 feeds compressed air or pressure oil, and rotation inlet suction port 2 is in communicating state with atmosphere, then compressed air or hydraulic oil enter in the clutch cylinder 11 via the passage of opening on screw mandrel (dotted portion represents to be opened in the pipe passage above the screw mandrel among the figure), promote clutch plunger 10 actions, because the free degree that clutch plunger 10 only moves up and down with respect to clutch cylinder 11 in design, and do not have along turning round the free degree that the axle center rotates mutually, in case clutch plunger compresses flywheel 9, be that clutch is connected, this moment, the rotation of flywheel 9 just drove screw mandrel 12 rotations by key 17, realize that slide block and screw mandrel rotate corresponding direction and move, reason same as described above, if make the moving direction of slide block with above-mentioned opposite, then need only make screw mandrel 12 opposite promptly passable with above-mentioned direction of rotation, rotate inlet suction port 1 and communicate with atmosphere this moment, and rotation inlet suction port 2 feeds compressed air or hydraulic oil, because the switched in opposite of flywheel 5 and flywheel 9, thereby the power of flywheel 5 drives screw mandrels 12 by key 16 and flywheel 5 turns to and the unequal angular velocity rotation by same; Realize and above-mentioned opposite action.Can know simultaneously by schematic diagram, if 1 and 2 rotate inlet suction ports all with situation that atmosphere communicates under, then screw mandrel 12 is in free state.In order to make pipeline be unlikely leakage, should seal reliably between the pipe passage.
