Description
Technical field
The present invention relates to a kind of press machine, particularly a kind of press machine source of the gas.
Background technique
The fast source of the gas of inserting of current domestic nearly all press machine is all buy part quick inserting joint by electromagnetic valve, and the solenoid valve source of the gas end of this kind of structure must air feed all the time, can not follow lifting and fall and controlling compressed-air actuated break-make of shuttle table.Therefore due to press structure, they generally will punch for installing quick inserting joint on column now.Traditional type is inserted source of the gas soon and be there is following shortcoming: 1, due to will perforate on column, column be stressed very complicated, have impact on the strength and stiffness of column.2, at every turn quick inserting joint must be inserted in column when using, and column is away from mould, there is flexible pipe centre, and often walking section in this section, space just operator, easily security incident occurs.3, tradition is fast inserts the automatic connecting and disconnecting that source of the gas can not realize source of the gas.
Summary of the invention
The object of this invention is to provide a kind of automation source of the gas mechanism, make air feed more convenient, improve the Security of work, eliminate safe hidden trouble.
The object of the present invention is achieved like this: a kind of automation source of the gas mechanism, comprise the shuttle table be arranged on above lathe base, described shuttle table is provided with gas source connector, described lathe base runs through source of the gas seat is installed, inverted shoulder hole is processed with in described source of the gas seat, slide and be provided with the vent piston exceeding lathe base end face in described shoulder hole top, described shoulder hole bottom is provided with air input joint, air input joint is threaded with source of the gas seat, described vent piston is connected through stage clip with between air input joint, described air input joint center offers runs through vent, described vent piston top offers blind hole of giving vent to anger, the bottom of blind hole of giving vent to anger offers circumferential air outlet hole.
When the present invention works, its state is divided into two kinds: 1. shuttle table lifts, 2. shuttle table falls, when worktable lifts, gas source connector does not act in vent piston, the screw thread termination flexible pipe of air input joint, gas is passed in flexible pipe, whole vent piston is by the pressure of gas and the active force of spring, thus the internal surface of vent piston and source of the gas seat is tightly fitted, again because of the cause of seal ring in vent piston and air input joint, cause the air cavity that formation one seals, this kind of state is that automation source of the gas is disconnected; When worktable falls, shuttle table bottom surface and lathe base are fitted, now gas source connector is tightly pressed in vent piston by the gravity of shuttle table, vent piston forces Compress Spring to shrink, thus vent piston is separated with source of the gas seat interior edge face, so pressurized air is just free to by air input joint, source of the gas seat, air outlet hole, blind hole of giving vent to anger, gas source connector also final metering-in control system, this mode of giving vent to anger is more reliably convenient, is determined the appropriate degree of spring pressure by the screw thread in rotary air inlet connector.Compared with prior art, beneficial effect of the present invention is, the present invention is by using the outlet passageway pressed in method unlatching source of the gas seat, make the conveying of pressed gas reliably convenient, in the course of conveying of pressed gas, due to the pressure fitted stage clip of gas self, the sealing between vent piston and gas source connector can be ensured, simultaneously, coordinating air outlet hole to realize the transmission of pressed gas by offering blind hole of giving vent to anger in vent piston, guaranteeing the reliability that pressed gas transmits and Security further.The present invention can be used in press machine.
As improvement of the present invention, described vent piston comprises round platform portion and cylindrical portion, and cylindrical portion is arranged on above round platform portion, arrange in inverted T-shaped, described cylindrical portion exceedes lathe base end face and arranges, and the root periphery of described cylindrical portion is processed with concave station, and described air outlet hole is opened on concave station.The vent piston of inverted T-shaped structure makes vent piston, and seal performance is better in off position, the concave station being simultaneously arranged on cylindrical portion root ensure that when the plane of shoulder hole has just been left in round platform portion, pressed gas can enter air outlet hole from the gap between concave station and shoulder hole sidewall, do not need air outlet hole by the time expose completely and realize the transmission of pressed gas, make the transmission of gas more quick.
In order to strengthen the sealability of vent piston further, the end face in the end face of described cylindrical portion, side and round platform portion is provided with seal ring.The sealing when seal ring being arranged on cylindrical portion end face guarantees that passage is opened, the sealing of passage open and close guaranteed by the seal ring being arranged on cylindrical portion side, and the sealing under pathway closure state guaranteed by the seal ring being arranged on round platform portion end face.
As improvement of the present invention, described air input joint comprises stud portion and sealed department, and described stud portion is connected with source of the gas seat inner thread, and the arranged outside of described sealed department has seal ring.Air input joint is threaded with source of the gas seat, the convenient pressure result regulating stage clip, along with length of side service time of stage clip, its yield strength can change, by regulating the position of air input joint, ensure that the service behaviour of stage clip, the seal ring being arranged on sealed department periphery ensure that the sealing between air input joint and source of the gas seat.
In order to make the installation of stage clip more reliable, the bottom of described vent piston is provided with boss, and one end of described stage clip is set on boss, and the top of described air input joint is arranged with compression spring, and the other end of stage clip is conflicted on compression spring.
In order to ensure the reliability be connected between gas source connector with vent piston, all fixed by screw between described gas source connector and shuttle table, between source of the gas seat and lathe base, and between gas source connector and shuttle table, be provided with adjustment pad.
