Abstract
Disclosed is a brake system of a press machine of a rigid clutch. A crankshaft is mounted on a machine body, a brake wheel is fixedly mounted at an end of the crankshaft, a fixing shaft and a cylinder are respectively mounted on side surfaces of a body of a machine tool, an upper cavity of a piston of a cylinder is directly communicated with the external atmosphere, a compression spring is mounted on the upper cavity of the piston, two ends of a brake belt are respectively hinged with the fixing shaft and a piston rod of the cylinder, a middle portion of the brake belt is wrapped with an outer circle of the brake wheel, an air inlet portion of a lower cavity of the cylinder is connected with an electromagnetic valve, an air inlet end of the electromagnetic valve is communicated with an air storage barrel, a clutch control pedal is mounted on a lower cavity portion of the body of the machine tool, and a travel switch is fixedly mounted below the clutch control pedal. The brake system can realize braking at an optional position, and has the advantages that a safety performance is good, electric energy consumption is low, friction loss among parts of a brake is low, and service lives of the parts are long.
Description
Technical field
The present invention relates to rigid clutch pressing machine, be specifically related to the brakes of rigid clutch pressing machine, belong to positive clutch or press technologies field.
Background technology
At present, in the formation of the braking system of rigid clutch pressing machine, mainly comprise braked wheel, the cam that is installed in crankshaft end, the brake band that is installed in the bed piece side; And the swelling device that links to each other with brake band; The main part of described brake band is installed in the brake cam with being divided into the envelope shape, and described swelling device is under cycle rotating cam control, and tension or loosen the brake band are realized the alleviation of braking or braking thus periodically.
By existing positive clutch formula forcing press braking system constituting and operation principle can be found out, though that the brake of this type has is simple in structure, the advantage that manufacturing cost is lower can't be implemented in the braking of optional position; So, have the relatively poor defective of security performance, simultaneously; Because the alleviation of this kind brake is to rely on the moment of torsion of bent axle to overcome braking torque by the strong hand to accomplish, so, not only there is the bigger defective of power consumption; Simultaneously, the brake band wearing and tearing are bigger, and the life-span is lower.
Summary of the invention
The objective of the invention is to: to the existing above-mentioned defective of brakes of existing rigid clutch pressing machine; The present invention provides a kind of brakes of novel rigid clutch pressing machine, and the brakes of the rigid clutch pressing machine that this kind is novel can be implemented in the braking of optional position, has the better safety performance advantage; Simultaneously; Because can before the alleviation of braking, can in time throw off between the parts of brake, it is less to have a power consumption; Frictional wear between the brake parts is less, parts long advantage in service life.
The present invention realizes that the technology scheme that above-mentioned purpose adopts is: a kind of brakes of rigid clutch pressing machine; It comprises: fuselage, bent axle, braked wheel, brake band, friction band, fixed axis, cylinder, controlled pedal, travel switch, magnetic valve, gas receiver, compressed air pump; It is characterized in that: crankshaft installed installs and fixes braked wheel in the end of bent axle on fuselage, on the side of the bed piece of braked wheel lower end, installs and fixes axle and cylinder respectively; Described steam-cylinder piston epicoele directly communicates with ambient atmosphere; The compression spring is installed between the piston rod of piston upper chamber, and the two ends of brake band are hinged with the piston rod of fixed axis and cylinder respectively, and the mid portion of said brake band and the excircle part of braked wheel be envelope mutually; Adopt the method fixed friction band connect inside at brake band; Air inlet position at the cavity of resorption of cylinder connects magnetic valve, and the air inlet end of magnetic valve is identical with gas receiver, and described gas receiver links to each other with compressed air pump; Cavity of resorption position at bed piece is equipped with the Clutch Control pedal, below the Clutch Control pedal, installs and fixes travel switch.
Operation principle of the present invention is: when not stepping on the clutch control pedal, magnetic valve is in the state of outage, the spring pulling brake band in the cylinder; Realize the effect of braking, step on following time at the clutch control pedal, travel switch is action and signal output not; When controlled pedal was stepped on down, the clutch of forcing press combined, and touches travel switch simultaneously; So under the control of travel switch, magnetic valve is connected; Compressed air in the gas receiver gets into the cavity of resorption of cylinder through magnetic valve, and overcomes the elastic force of spring, take-off the brake band.
Beneficial effect: can find out by the access node structure that by operation principle of the present invention the present invention can be implemented in the braking of optional position, have the better safety performance advantage; Simultaneously; Because can before the alleviation of braking, can in time throw off between the parts of brake, it is less to have a power consumption; Frictional wear between the brake parts is less, parts long advantage in service life.
