Description
Technical field
The present invention relates to a kind of metal forming machinery.
Background technology
The punching machine Clutch and brake is arranged at bent axle together near on flywheel one end at present, and patent No. ZL99805307.4 discloses a kind of punching machine clutch brake apparatus; The Clutch and brake of this punching machine clutch brake apparatus joins together and is arranged at bent axle near on flywheel one end, because joining together, Clutch and brake is arranged at bent axle near on flywheel one end, make crankshaft two end be subjected to force unbalance, make crankshaft support spare, lost efficacy easily such as bearing, reduction of service life, and affect the forcing press operating accuracy.When this punching machine clutch brake apparatus is used for high-speed mechanical press machine, its weak point is even more serious, this punching machine clutch brake apparatus adopts the hydraulic cylinder switching mechanism that Clutch and brake is switched, complex structure, and easily produce seepage.And existing clutch exists complex structure, space requirement large (placing outside the flywheel), the large defectives such as (clutch mainly place on the bent axle) of braking inertia.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this invention is to provide a kind of metal forming machinery, the structural design that adopts Clutch and brake to separate, clutch adopts pneumatic control, simple in structure, carry-over moment is reliable, and overload operation safety increases flywheel inertia (housing and flywheel rotate simultaneously), compressed air delivery is simple and reliable, the cylinder of the approximate sealing of housing, good airproof performance, the transmitting accuracy and the service life that are conducive to improve clutch.
To achieve the above object, the present invention has adopted following technical scheme:
Metal forming machinery, comprise bent axle, one end of described bent axle is installed brake, the other end of described bent axle is installed clutch, described clutch comprises the flywheel that is set in successively on the bent axle, driven axle sleeve and driving disc spacing pressing, flywheel is installed on the bent axle by bearing, driven axle sleeve and driving disc spacing pressing are set in the flywheel cavity, flywheel cavity outside is fixedly connected with a housing, driven axle sleeve is fixedly connected with bent axle, be inlaid with a plurality of removable brake pads on the outer ring of driven axle sleeve, the driving disc spacing pressing empty set on bent axle and by a plurality of trundles with circumferentially fixing be connected the mode that can move and be connected with housing, be arranged with a plurality of springs that can give the close housing trend of driving disc spacing pressing on the trundle, thereby nested being slidingly connected consists of the tubular cylinder chamber between driving disc spacing pressing and the housing between driving disc spacing pressing and housing, this tubular cylinder chamber is communicated with the passage that is located at the housing center, and this tubular cylinder chamber is by being located at the seal ring seal between driving disc spacing pressing and the housing.
The present invention has been owing to adopted above technical scheme, and the structural design that adopts Clutch and brake to separate makes that crankshaft two end is stressed tends to balance; The clutch volume is little, lightweight, moves more sensitively, in the service life of having improved crankshaft support spare, has improved the operating accuracy of high-speed mechanical press machine; Clutch adopts pneumatic control, and simple in structure, carry-over moment is reliable, overload operation safety increases flywheel inertia (housing and flywheel rotate simultaneously), and compressed air delivery is simple and reliable, the cylinder of the approximate sealing of housing, good airproof performance, the transmitting accuracy and the service life that are conducive to improve clutch.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the right view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is made a detailed explanation.
Embodiment 1:
Such as Fig. 1, a kind of metal forming machinery shown in Figure 2, comprise bent axle 1, one end of described bent axle 1 is installed brake, the other end of described bent axle 1 is installed clutch, described clutch comprises the flywheel 3 that is set in successively on the bent axle 1, driven axle sleeve 8 and driving disc spacing pressing 9, flywheel 3 is installed on the bent axle 1 by bearing 2, driven axle sleeve 8 and driving disc spacing pressing 9 are set in flywheel 3 cavitys, flywheel 3 cavitys outside is fixedly connected with a housing 7, driven axle sleeve 8 is fixedly connected with bent axle 1, be inlaid with a plurality of removable brake pads 6 on the outer ring of driven axle sleeve 8, driving disc spacing pressing 9 empty sets on bent axle 1 and by a plurality of trundles 5 with circumferentially fixing be connected the mode that can move and be connected with housing 7, be arranged with a plurality of springs 4 that can give driving disc spacing pressing 9 close housing 7 trend on the trundle 5, thereby nested being slidingly connected consists of the tubular cylinder chamber between driving disc spacing pressing 9 and the housing 7 between driving disc spacing pressing 9 and housing 7, this tubular cylinder chamber is communicated with the passage 71 that is located at housing 7 centers, and this tubular cylinder chamber is by being located at the seal ring seal between driving disc spacing pressing 9 and the housing 7.
When the passage 71 obstructed Compressed Gas on the housing 7, thereby owing to the tension force of spring 4 separates near housings 7 driving disc spacing pressing 9 with driven axle sleeve 8, so that the rotary power of flywheel 3 can not be delivered to driven axle sleeve 8.When the passage 71 on the housing 7 passes into Compressed Gas, when compressed air enters the tubular cylinder chamber, promotion driving disc spacing pressing 9 overcomes spring force and moves the mobile brake pad 6 of inlaying in the driven axle sleeve 8 of compression, so that between the driving disc spacing pressing 9, driven axle sleeve 8, flywheel 3 threes by mobile brake pad 6 synchronous rotations bonded to each other, thereby realize the transmission of power source.When compressed gas source stops, driving disc spacing pressing 9 retracts by the tension force of housing 7 interior Compress Springs, decontrols the compression to mobile brake pad 6, becomes free separated position between driving disc spacing pressing 9, driven axle sleeve 8, flywheel 3 threes, realizes the disengaging of power source.
