Abstract
The utility model discloses a pipe purging device which comprises a main shaft, a driving device, a nitrogen channel and a positioning device. A pipe is wound on the main shaft in a surrounding mode, the driving device is used for driving the main shaft to rotate around the axis of the main shaft, the nitrogen channel is filled with nitrogen, the positioning device comprises an air cylinder which is used for grasping an air claw, driving the air claw to move, and enabling an inner cavity of a copper pipe and the nitrogen channel to be communicated, the driving device comprises a motor, a driving gear driven by the motor, and a driven gear meshed with the driving gear, and the driven gear is fixedly connected with the main shaft. The air cylinder drives the air claw to move. The pipe is wound at one end of the main shaft, a conductive sliding ring is arranged at the other end of the main shaft, the nitrogen channel, a compressed air channel and a wire penetrate through the conductive sliding ring and the main shaft, the wire is electrically connected with the air cylinder, and the compressed air channel is communicated with the air cylinder. According to the structure, purging operation can be automatically achieved, and due to the fact that the air cylinder abuts against the pipe in the process of purging, the phenomenon that the pipe is blown out due to differential pressure cannot happen.
Description
Technical field
Related to a kind of tubing blow device in the utility model.
Background technology
In the prior art, nitrogen purging device is the auxiliary equipment of big charging tray rolling, is for will in the continuous nitrogen blowing of pipe material inner wall, making the inwall of copper pipe reach higher cleannes requirement through online annealing back copper pipe wrapup procedure.
The nitrogen purging device of original big charging tray rolling can't be switched on, and only behind starting device, allows equipment move in the speed of 25M/min earlier.By manually tubing being inserted in the sealing shroud, open nitrogen then, the copper pipe inwall is purged.During operation, to having relatively high expectations of operating personnel, and there is certain potential safety hazard, simultaneously can't guarantee that copper pipe successfully inserts the success rate of sealing shroud, even successfully copper pipe is inserted in the sealing shroud, because nitrogen pressure is higher than the external world, copper pipe also might be blown sealing shroud.

Positioner, it comprises be used to the cylinder of catching the gas pawl, driving the motion of gas pawl and the inner chamber of copper pipe is connected with channel of nitrogen.
Preferably, described drive unit comprises motor, by motor-driven driving gear, the driven gear that is meshed with driving gear, and described driven gear and described main shaft are fixedly connected.
Preferably, described air cylinder driven gas pawl moves.
Preferably, one end of described main shaft is wound with tubing, the other end of described main shaft is provided with a conducting slip ring, pass channel of nitrogen, compressed air channel and lead in described conducting slip ring and the described main shaft, described lead is electrically connected mutually with described cylinder, and described compressed air channel is connected with described cylinder.
Preferably, the exit of described channel of nitrogen is provided with sealing shroud.
Preferably, it comprises that also one is used for nitrogen is purged the PLC that controls.
The utility model adopts above structure, realization purge operations that can automation; Cylinder props up tubing in purge, thereby tubing can be owing to pressure reduction is blown.。
Description of drawings
Accompanying drawing 1 is the structural representation of the tubing blow device in the utility model.
In the accompanying drawing: 1, motor; 2, driving gear; 3, driven gear; 4, cylinder; 5, gas pawl; 6, sealing shroud; 7, main shaft; 8, conducting slip ring; 9, channel of nitrogen; 10, compressed air channel; 11, lead.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
Among the embodiment of the present utility model, a kind of tubing blow device, it comprises main shaft 7, drive unit, channel of nitrogen 9 and positioner.
Main shaft 7 is the agent structure of this blow device.In an end of main shaft 7, the tubing coiling is placed on the main shaft 7.Main shaft 7 can be around the axis rotation of himself, and in rotary course, tubing is also followed main shaft 7 rotation rollings.
Drive unit comprises motor 1, the driven gear 3 of the transmission that is meshed by the driving gear 2 of motor 1 driven rotary, with driving gear 2, driven gear 3 is fixedly connected with main shaft 7, in the process of motor 1 running, driving gear 2 drives driven gear 3 rotations, thereby drives main shaft 7 around himself axis rotation.
Be connected with nitrogen in the channel of nitrogen 9, when switch opens, nitrogen flows to the port of export from the arrival end of channel of nitrogen 9, and the inwall to tubing purges from the port of export.
Positioner comprises gas pawl 5, cylinder 4.Gas pawl 5 can be caught tubing, and is catching under the situation of tubing, and cylinder 4 drives 5 motions of gas pawl, makes tubing aim at channel of nitrogen 9.In the present embodiment, cylinder 4 is linear cylinder 4, thereby the motion of gas pawl 5 is linear movement.
In order to increase the sealing of gas pawl 5 and channel of nitrogen 9, the exit of channel of nitrogen 9 is provided with sealing shroud 6.
Preferably, an end of the utility model main shaft 7 is wound with tubing, and the other end is provided with conducting slip ring 8.Channel of nitrogen 9, compressed air channel 10, lead 11 have been passed in the conducting slip ring 8.Channel of nitrogen 9, compressed air channel 10 and lead 11 enter main shaft 7 from conducting slip ring 8, and pass that the end that is wound with tubing from main shaft 7 passes behind the inner chamber of main shaft 7.
In the utility model, what adopt is the conducting slip ring 8 of the SRT025-24-2Q of Hangzhou Prosper Mechanical ﹠ Electrical Technology Co., Ltd., this conducting slip ring 8 keeps the static relatively of channel of nitrogen 9, compressed air channel 10, lead 11 in main shaft 7 rotation processes, can not make that this three produces twisted wire.
Preferably, the tubing blow device comprises that also one is used for nitrogen is purged the PLC that controls.
Operation principle of the present utility model is as follows:
Drive driving gear 2 by motor 1, drive driven gear 3 rotations by driving gear 2 again, 7 rotations of driven gear 3 drive shaft.In main shaft 7 rotary courses, by PLC control, catch tubing by gas pawl 5, after tubing is caught by gas pawl 5, cylinder 4 is released gas pawl 5 and tubing is inserted in the channel of nitrogen 9, and PLC opens channel of nitrogen 9, and nitrogen purges in pipe material inner wall by channel of nitrogen 9.
