Description
Technical field
The present invention relates to a kind of forcing press.
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 brake structural is complicated, and overall weight is large.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this invention is to provide a kind of forcing press, the structural design that adopts clutch to separate with brake, brake adopts pneumatic control, and is simple in structure, braking is sensitive, whole lightweight.
To achieve the above object, the present invention has adopted following technical scheme:
A kind of forcing press, comprise pressure frame and bent axle, one end of described bent axle is installed clutch, the other end of described bent axle is installed brake, described brake comprises brake cylinder casing, trig loop and friction band, brake cylinder casing is fixedly connected with bent axle, trig loop and friction band empty set are in the brake cylinder casing outside, trig loop is the opening ring-type, the friction band is fixed on the inwall of trig loop, trig loop right openings place is equipped with cylinder, the piston rod of cylinder passes stage clip, the two ends rear thread of trig loop opening part connects stop nut, and wherein, described brake cylinder casing has endoporus and cavity, described stage clip one end and cylinder offset, one end of the stage clip other end and trig loop opening part offsets, and the other end and the stop nut of trig loop opening part offset, and described trig loop left side is provided with fixing hole, described trig loop downside is provided with the kidney-shaped installing hole, and described trig loop passes through fixing hole, the kidney-shaped installing hole is installed on the pressure frame.
The brake of this programme, brake cylinder casing adopts endoporus, cavity structure, realizes whole lightweight; Trig loop is the aperture variable form, realizes clamping under cylinder action and opens; The friction band changes with trig loop for durable changeable-shaped.When compressed air enters cylinder block by air inlet, piston rod stretches out, and makes trig loop and friction band that shape deformation not occur, and does not produce friction, realization power source continuous rotation between brake cylinder casing and the friction band; When compressed air stops, piston rod retracts by Compress Spring tension force, and trig loop with the friction band shape deformation occurs, and the distortion of friction band internal diameter is dwindled, and holds brake cylinder casing tightly, making friction band and brake cylinder casing produce friction, realizes stopping of power source.
The present invention is owing to adopted above technical scheme, and the structural design that adopts Clutch and brake to separate makes the brake action more sensitive, and Clutch and brake divides and is located at crankshaft two end, makes the stressed more steady equilibrium in crankshaft two end and lathe bed both sides; Improve the service life of crankshaft support spare, improved the operating accuracy of high-speed mechanical press machine, reduced maintenance difficulty; The employing pneumatic mechanism switches Clutch and brake, and is simple in structure, overcome the deficiency of hydraulic mechanism easy to leak, improved operating environment.And in the brake, brake cylinder casing adopts endoporus, cavity structure, realizes whole lightweight; Trig loop is the aperture variable form, realizes clamping under cylinder action and opens; The friction band changes with trig loop for durable changeable-shaped.Have simple in structure, the advantages such as the braking sensitivity is reliable, whole lightweight.
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 forcing press shown in Figure 2, comprise pressure frame and bent axle 7, one end of described bent axle 7 is installed clutch, the other end of described bent axle 7 is installed brake, described brake comprises brake cylinder casing 1, trig loop 3 and friction are with 2, brake cylinder casing 1 is fixedly connected with bent axle 7, trig loop 3 and friction are with 2 empty sets in brake cylinder casing 1 outside, trig loop 3 is the opening ring-type, friction is fixed on the inwall of trig loop 3 with 2, trig loop 3 right openings places are equipped with cylinder 5, the piston rod of cylinder 5 passes stage clip 4, the two ends 31 of trig loop 3 opening parts, 32 rear threads connect stop nut 6, wherein, described brake cylinder casing 1 has endoporus 12 and cavity 11, described stage clip 4 one ends and cylinder 5 offset, one end 31 of stage clip 4 other ends and trig loop 3 opening parts offsets, the other end 31 and the stop nut 6 of trig loop 3 opening parts offset, described trig loop 3 left sides are provided with fixing hole 33, described trig loop 3 downsides are provided with kidney-shaped installing hole 34, and described trig loop 3 is by fixing hole 33, kidney-shaped installing hole 34 is installed on the pressure frame.
The brake course of work is as follows: when compressed air enters cylinder 5 when interior by air inlet, piston rod stretches out, and makes trig loop 3 and friction be with 2 shape deformation does not occur, and does not produce CONTACT WITH FRICTION between brake cylinder casing 1 and friction are with 2, realization bent axle 7 continuous rotations; When compressed air stops, piston rod retracts by Compress Spring 4 tension force, and trig loop 3 is with 2 shape deformations occur with friction, and friction is with the distortion of 2 internal diameters to dwindle, and holds brake cylinder casing 1 tightly, making friction be with 2 to produce friction with brake cylinder casing 1, realizes that bent axle 7 stops operating.
