Description
Technical field
The utility model belongs to mechanical press technical field, particularly relates to a kind of mechanical press pneumatic clutch swivel joint.
Background technique
Swivel joint is air inlet, the exhaust hinge of mechanical press pneumatic clutch, when mechanical press is started working (when single stroke starts), after should following the first air inlet of break, clutch, the time difference of air inlet prevents clutch and break from mutually interfering; Answer during exhaust that clutch is first vented, the time difference of break final vacuum prevents both from mutually interfering, to ensure that mechanical press normally works.
But, present stage, swivel joint used only had a working hole, namely air inlet and exhaust are all completed by this working hole, thus when air inlet and exhaust conversion, the conversion time that meeting life period is longer is poor, time difference (the first air inlet of break followed when difference starts with above-mentioned single stroke this conversion time, time difference and the clutch of air inlet after clutch are first vented, the time difference of break final vacuum) mutually conflict, when causing clutch and break action, the time difference of action does not between the two exist (problem that clutch and break action simultaneously can occur), thus mutually interfere during both actions, influence each other, and then affect the normal work of mechanical press.
Model utility content
The purpose of this utility model is to provide a kind of mechanical press pneumatic clutch swivel joint, mutual noninterference during to reach clutch and break action, is independent of each other, and ensures the object that mechanical press normally works.
For solving the problems of the technologies described above, the technical solution of the utility model is: mechanical press pneumatic clutch swivel joint, comprise the valve seat be connected with baffler, the side of described valve seat is rotatablely equipped with the rotating disc be fixedly connected with clutch, and the opposite side of described valve seat is provided with suction valve;
One end near described clutch on described rotating disc is provided with a chute, is provided with spool in described chute; The other end of described rotating disc passes described valve seat and extends in described suction valve, is provided with the gas-entered passageway being communicated with described suction valve and described chute in described rotating disc;
Described spool is provided with an air inlet groove be communicated with described chute away from one end of described clutch, described spool is provided with a curve bath be communicated with gateway on described clutch near one end of described clutch, described spool is gone back circular array and show several inlet holes, described inlet hole is all communicated with described curve bath with described air inlet groove;
Be provided with exhaust portion between described rotating disc and described clutch, on described rotating disc, annular array has the exhaust port that some and described exhaust portion is connected; The relief opening that described valve seat is provided with an exhaust passage consistent with described valve seat bearing of trend and is communicated with described exhaust passage, described exhaust passage is communicated with described exhaust port, and described baffler is arranged on described relief opening.
Improve as one, between described valve seat and described rotating disc, be provided with at least two bearings be arranged side by side.
As further improvement, described rotating disc is provided with a back-up ring near one end of described suction valve, described bearing near described suction valve one end leans on described back-up ring, described bearing near described clutch one end leans on the shaft shoulder of described rotating disc, is provided with axle sleeve described in adjacent two between bearing.
As further improving, described spool is provided with frustum near one end of described clutch, and the diameter of described frustum small end is less than the diameter of described gateway; Described clutch is provided with a cone shape hole suitable with described frustum, and described cone shape hole is communicated with described gateway.
As further improving again, between described spool and described rotating disc, being provided with the first seal element, between described rotating disc and described suction valve, being provided with the second seal element.
As further improving, described spool is aluminium spool.
Owing to have employed technique scheme, the beneficial effects of the utility model are:
Because the gas-entered passageway on rotating disc is communicated with by the inlet hole on spool with the gateway on clutch, exhaust portion between rotating disc and clutch and exhaust port, thus operationally, in the process that clutch drives rotating disc to rotate, when wanting air inlet, because suction pressure is higher than clutch cavity internal air pressure, spool is compacted and recline on clutch, realizes sealing and completes air inlet by the gas-entered passageway that is interconnected, gateway and inlet hole; When being vented, because clutch cavity internal air pressure is higher than inlet end pressure, spool is open mouth, and gas is entered exhaust portion and discharged rapidly by the exhaust port on rotating disc.In sum, the air inlet of this swivel joint and exhaust have respective air-flow path, air inlet and exhaust process are more directly rapidly, compared with tradition, the conversion time greatly reducing air inlet and exhaust process is poor, the minimizing that this conversion time is poor, time difference (the first air inlet of break followed when single stroke is started, time difference and the clutch of air inlet after clutch are first vented, the time difference of break final vacuum) meet the requirements, thus operationally, the larger time difference can be there is, ensure the succession of clutch and break successively action, can not occur mutually to interfere and interactional problem, and then ensured the normal work of mechanical press.
Owing to being provided with at least two bearings be arranged side by side between valve seat and rotating disc, thus not only ensure that by bearing the smoothness that rotating disc rotates in valve seat, and, the axial force produced when can also carry clutch air inlet and exhaust.
Bearing due to two ends leans respectively on the shaft shoulder and back-up ring, is provided with axle sleeve between adjacent two bearings, thus ensure that the stationarity of bearing, and then ensure that the stability that rotating disc rotates in valve seat.
Because spool is provided with frustum, thus to be coordinated with the cone shape hole on clutch by frustum and realize end face seal, good sealing effect, avoid and use Sealing easily aging or wearing and tearing, cause leaking gas and affect the problem that mechanical press normally works.
Owing to being provided with the first seal element between spool and rotating disc, between rotating disc and suction valve, be provided with the second seal element, thus ensure that sealing by the effect of two seal elements, for the smooth air inlet of clutch and exhaust are laid a good foundation.
Because spool is aluminium spool, compared with tradition, not only effectively alleviate the quality of spool, meanwhile, also assures that the smoothness of spool action in the chute of valve seat.
