Technical Field

The invention relates to the technical field of production of high-pressure gas cylinders, in particular to a feeding device of a tube drawing bench and a using method thereof.

Background

During the cold drawing work of the gas cylinder tube, after feeding, the gas cylinder tube needs to be inserted into the core rod, and the drawing die on the core rod is matched with the gas cylinder tube so as to be used for drawing the gas cylinder tube subsequently. When the cold drawing process is completed, the core bar and the drawing die are dismounted together from the gas cylinder tube, and because the core bar has a certain length, the core bar needs to move back along the axial direction for a long distance to feed the next gas cylinder tube workpiece, and a certain number of supporting riding wheels are required to be arranged below the core bar to support the core bar in the moving process of the core bar, however, because the drawing die is arranged at one end of the core bar, the drawing die collides with the supporting riding wheels at the lower part in the driving process of the core bar, the core bar needs to be dismounted from the core bar manually by a worker after being dismounted from the gas cylinder tube every time, and then the core bar can move back to avoid the interference caused by the collision of the drawing die with the supporting riding wheels, and the drawing die is mounted at one end of the core bar after the core bar completely returns back to the initial position, which undoubtedly increases the labor intensity of the worker, and the production efficiency is seriously lowered.

More preferably, the left and right sides of the bottom of the support are respectively hinged with a rectangular tube.

More preferably, the supporting idler comprises two conical wheels and a cylinder coaxially connected between the two conical wheels.

In addition, the invention also provides a method for using the feeding device of the tube drawing bench, which comprises the following steps:

firstly, the oil cylinder drives the support to swing forwards, so that the supporting riding wheel is lowered to the lowest position to wait for feeding of the gas cylinder pipe.

And secondly, after the gas cylinder pipe is fed above the base and falls on the supporting rod, the oil cylinder drives the support to swing backwards, so that the supporting riding wheel supports the gas cylinder pipe.

And thirdly, the core bar moves forwards to enable the drawing die to be matched with the gas cylinder tube and push the gas cylinder tube to move forwards on the supporting riding wheel, so that the gas cylinder tube can be matched with the cold drawing machine, then the cold drawing machine draws the gas cylinder tube, and in the process, the supporting riding wheels which are separated from the contact with the gas cylinder tube are lifted one by one to be in contact with the core bar.

And fourthly, after the cold drawing machine finishes drawing the gas cylinder pipe, the drawing die is separated from the gas cylinder pipe, the core rod gradually retreats towards the initial position, and in the process, the supporting riding wheels are sequentially lowered from front to back one by one so as to sequentially avoid the drawing die.

And fifthly, when the core rod retreats to the initial position, all the supporting riding wheels are lowered to the lowest position to wait for feeding of a next gas cylinder pipe.
