Abstract

An automatic compensation brake used in the mechanical industry, in particular to a metal wire processing process, which solves the defect of poor braking effect in the prior art. The hydraulic cylinder is characterized by comprising two oil cylinders (9), a body seat (8) and a support plate (11). When braking, the two oil cylinders (9) clamp the rotating brake disc (5) under the action of high-pressure oil (12) to achieve the purpose of automatic braking. Has the function of automatically compensating the distance between the brake disc (5) and the friction plate (22). The brake is not only suitable for a strand machine, a wire drawing machine and a wire winding machine, but also suitable for automobiles, motorcycles and even places equipped with brake discs in the mechanical industry, and is an ideal brake device for various mechanical equipment.

Description

Self-compensation brake

The utility model relates to employed break in a kind of mechanical industry, employed automatic compensation break in particularly a kind of metal wire rod course of working.

Employed break is of a great variety, different in the prior art machinery industry.Its structure has machinery, hydraulic pressure, pneumatic, and the expanding brake formula is arranged, also have band brake type or the like, its braking effect cuts both ways.But they all exist a common deficiency, and promptly behind friction disc wear, the distance between whirler dish and the friction plate becomes big, influences braking effect.As the break on the automobile, after use after a while, must adjust the distance between friction plate and the brake disc, otherwise will influence its braking effect, and more renewal of facing renewal is extremely inconvenient.The break of the Bunching machine of metal wire rod processing usefulness in the prior art and for example, not only braking effect is poor for it, and noise is also big especially, directly influences quality, the benefit of product, harm operator's health, environmental benefit is poor.

The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, and provide a kind of distance that can not only adjust automatically between brake dish and the friction plate, and friction plate can also compensate it after being worn automatically, compact structure, flexible, braking is rapidly reliable, noise is little, be not only applicable to employed Bunching machine, drawbench, winding machine in the metal wire rod course of working, also be applicable to automobile, motorcycle, so all local employed automatic compensation breaks of being furnished with the brake dish of mechanical industry.

Technical solution of the present utility model is: mainly be made of oil cylinder (9), body seat (8) and support plate (11).By connecting bolt and oil pipe (10) two oil cylinders (9) are communicated with high pressure oil (12).Brake dish (5) is positioned at the central authorities of break (4).Two oil cylinders (9) are under the effect of high pressure oil (12) during braking, and the brake dish (5) with rotation clamps simultaneously, thereby reach the purpose of braking.Its key is can be to the wear extent of friction plate (22), and promptly brake dish (5) is compensated automatically with the spacing of friction plate (22).

The utility model has following advantage compared to existing technology:

1, can not only adjust distance between brake dish and the friction plate automatically, and can also be compensated friction plate after the wearing and tearing and the distance between the whirler dish automatically.

2, its compact structure, small and exquisite, flexible, braking is reliable rapidly in important being, and noise is little, be not only applicable to Bunching machine, drawbench, winding machine, also be applicable to automobile, motorcycle, so all places of being furnished with the brake dish of mechanical industry, be the desirable braking device of various machinery.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the utility model mechanical structure principle schematic.Wherein 1 is the transmission handle, and 2 is pressurized machine, and 3 is oil sump, and 4 is break, and 5 is the brake dish.

Fig. 2 is the utility model pneumatic type structural principle schematic representation.Wherein 2 is pressurized machine, and 3 is oil sump, and 4 is break, and 5 is the brake dish, and 6 is pressurized air, and 7 is solenoid valve.

Fig. 3, Fig. 4 and Fig. 5 are respectively overall structure outward appearance plan view of the present utility model, left side view and plan view.Wherein 5 is the brake dish, and 8 is the body seat, and 9 is oil cylinder, and 10 is oil pipe, and 11 is support plate, and 12 is high pressure oil, and 13 is outlet valve.

Fig. 6 is the A-A sectional view on the utility model Fig. 4, the overall structure schematic representation when promptly oil cylinder 9 is in off working state.Wherein 14 is cylinder body, and 15 is concavo-convex seat, and 16 is washer, and 17 is central shaft, and 18 is the convex cover, and 19 are locking spring radially, and 20 is Returnning spring, and 21 is piston, and 22 is friction plate, and 5 is the brake dish, and the arrow indication is a high pressure oil 12.

Fig. 7 is the A-A sectional view on the utility model Fig. 4, i.e. overall structure schematic representation during oil cylinder 9 in running order (braking state).Wherein 14 is cylinder body, and 15 is concavo-convex seat, and 16 is washer, and 17 is central shaft, and 18 is the convex cover, and 19 are locking spring radially, and 20 is Returnning spring, and 21 is piston, and 22 is friction plate, and 5 is the brake dish, and the arrow indication is a high pressure oil 12.

The utility model is described in further detail below in conjunction with accompanying drawing and embodiment: oil cylinder (9) is made up of cylinder body (14) and piston (21).By concavo-convex seat (15) central shaft (17) is fixed in the type hole of cylinder body (14) bottom, is located at the central authorities of oil cylinder (9).On piston (21), have the distance that can guarantee between washer (16) and convex cover (18) left end and meet pack into successively in the step hole of the numerical value that requires radially locking spring (19), convex cover (18), Returnning spring (20) and washer (16), and at the oral area of step hole that it is locked, washer (16) and piston (21) are connected as a single entity.With piston (21) cylinder body (14) of packing into, central shaft (17) then inserts radially in the locking spring (19).Like this, because the frictional force between warp-wise locking spring (19) and the central shaft (17) is greater than the frictional force between piston (21) and the cylinder body (14), and greater than the elastic force of Returnning spring (20), and make the thrust of time spent less than high pressure oil (12), when high pressure oil (12) is done the time spent, piston (21) at first is pushed, and because of piston (21) and catch (16) are connected as a single entity, catch (16) also moves and compression reseting spring (20) simultaneously.When catch (16) with after convex cover (18) left end contacts, also promote simultaneously convex cover (18) and radially locking spring (19) move, contact with the brake dish (5) of rotation and reach the purpose of braking until the right-hand member of friction plate (22).When high pressure oil (12) fails, Returnning spring (20) is again by means of the central shaft (17) and the frictional force of locking spring (19) radially, piston (21) is rebounded, and its distance of being rebounded equals the distance between catch (16) and the convex cover (18), brake off state rapidly just.In use, friction plate (22) constantly is worn, and high pressure oil (12) then ceaselessly promotes radially locking spring (19) again and moves, and reaches the purpose of automatic compensation.Fail and machinery when running well at high pressure oil (12), remain desired numerical distance between friction plate (22) and the inventory (5), make its braking rapidly, reliably.When friction plate (22) exhausts, only need its replacing, can continue to use.
