Before the copper pipe subjected to traction pretreatment passes through the die hole of the drawing die 12, a motor 217 is started, the motor 217 and a transmission gear sleeve 218 are kept relatively fixed through the external expansion of an electric external expansion device, so that the transmission gear sleeve 218 rotates and drives a first guide gear 214 to rotate, further, a rotating ring plate 28 is driven to synchronously rotate and elastically shrink a torsion spring 215, the rotating ring plate 28 rotates under the guiding action of an arc groove 29 and a guide groove 24, a guide post 27 is pushed to drive a movable plate 26 to move, a guide block 25 on the movable plate 26 slides in the guide groove 24, the movable plate 26 is driven to move, a plurality of movable plates 26 gradually shrink, the caliber of a ring-like formed by the movable plate is gradually increased until a first contact point on a first contact point column 219 is abutted with a second contact point on a second contact point column 220, at this time, the motor 217 is closed, and the plurality of movable plates 26 completely shrink, and the caliber of the ring-like formed by the movable plate is identical with the caliber of the die hole of the drawing die 12;
Then, the pretreated copper pipe is pulled to pass through a die hole of the drawing die 12 and then passes through a ring-like formed by contraction of a plurality of moving plates 26, so that a plurality of second balls 211 are contacted with the surface of the pulled copper pipe, and the pulled copper pipe can pass through the ring-like formed by the plurality of moving plates 26 under the rolling action of the second balls 211;
At this time, the clamping device 14 clamps part of the copper pipe passing through the plurality of moving plates 26, and then drives the hydraulic telescopic rod 13 to shrink, so that the copper pipe is drawn;
When the copper pipe is drawn, the electric outward expanding device is reset, under the action of elastic release of the torsion spring 215, the rotary ring plate 28 is reset, the plurality of moving plates 26 move towards the direction close to the middle of the fixed base 23 until the first ball 210 or the second ball 211 on the moving plate 26 is in abutting joint with the drawn copper pipe, and at the moment, the first contact on the first contact column 219 is not in abutting joint with the second contact on the second contact column 220;
With the drawing of the copper pipe, the drawn copper pipe passes through a ring-like ring formed by a plurality of moving plates 26, and if the caliber of the drawn copper pipe is the same as the caliber of the die hole of the drawing die 12, the plurality of moving plates 26 are completely contracted through the operation, and the caliber of the drawn copper pipe meets the production requirement;
If the caliber of the drawn copper pipe is different from the caliber of the die hole of the drawing die 12, when the first contact point 219 on the first contact point post is not in contact with the second contact point 220 again, closing the hydraulic telescopic rod 13 to stop moving, and at the moment, the caliber of the drawn copper pipe is smaller than the caliber of the die hole of the drawing die 12, so that the production requirement is not met;
when contact one on contact post one 219 and contact two on contact post two 220 again no longer abut, hydraulic telescoping rod 13 ceases to move, at which point copper tubing is no longer pulled, and motor telescoping rod 33 is actuated to extend its output, causing rack one 35 to move with cutter 34,
In the moving process of the first rack 35, the second rack 39 is moved towards the direction close to the cutter 34 by the rotation of the limiting post 36, the connecting rod 310 is driven to move synchronously, in the moving process of the connecting rod 310, the arc plate 314 is firstly abutted with the pulled copper pipe, and at the moment, the cutter 34 does not cut the copper pipe between the cutter 34 and the first rack 35;
Along with the continuous movement of the connecting rod 310, the rectangular rod 312 is moved and elastically stretches the reset spring 313, and then the copper pipe is fixed through the two arc plates 314 until the cutter 34 cuts off the copper pipe between the cutter 34 and the rack one 35, and at the moment, the electric telescopic rod 33 stops stretching;
After the copper pipe between the cutter 34 and the first rack 35 is cut off by the cutter 34, the clamping device 14 is enabled to not clamp the section of copper pipe any more, the section of copper pipe is taken out, and the drawing operation is carried out again after the hydraulic telescopic rod 13 is repaired.
