In the copper pipe coil automatic winding machine, the wire outlet pipe 4 is slidably arranged at one side outside the coil winding die 1, so that the rotating shaft 2 can drive the wire outlet pipe 4 to move parallel to the axis of the coil winding die 1 through the transmission mechanism 5, and each time a coil is wound, the wire outlet pipe 4 moves forward by the length of one screw pitch of the coil, so that the wire outlet position of the wire outlet pipe 4 always corresponds to the position where the surface of the coil winding die 1 is winding, and the coil on the surface of the coil winding die 1 is prevented from being pulled along the axial direction of the coil to cause uneven coil winding; in addition, the rotation driving mechanism 3 is shared by the movement of the outlet pipe 4 and the rotation of the coil winding die 1 as a power source, so that the overall structure of the device is simpler.
Specifically, the automatic copper pipe coil winding machine further comprises a frame 6, a mounting seat 7, a sliding rail 8 and a sliding block 9, wherein the mounting seat 7 is fixedly arranged on the frame 6, the sliding rail 8 is detachably and fixedly arranged on the mounting seat 7, the sliding block 9 is slidably arranged on the sliding rail 8, and the sliding rail 8 can guide the sliding block 9, so that the sliding block 9 slides on the sliding rail 8 in the axial direction parallel to the rotating shaft 2; the outlet pipe 4 is detachably and fixedly arranged on the sliding block 9.

Since the external wire supply device (such as a wire coil) is generally fixed, in order to avoid that the copper wire is seriously bent when entering the outgoing wire 4 due to the fact that the outgoing wire 4 moves too far from the external wire supply device, as a preferred embodiment, the outgoing wire 4 comprises a straight pipe section 41 and an expanded pipe section 42 which are fixedly connected, and the inner diameter of the expanded pipe section 42 is far greater than the diameter of the copper wire, and in particular, the expanded pipe section 42 is a horn pipe; the end of the straight tube section 41 away from the expanded tube section 42 faces the coil winding die 1.
It will be appreciated that the enlarged pipe section 42 serves as a transition section before the copper pipe line enters the straight pipe section 41, so as to increase the angle of the bending position of the copper pipe line, so as to avoid serious bending when the copper pipe line enters the outgoing pipe 4 due to too far distance from the external wire supply device when the outgoing pipe 4 moves.
As a preferred embodiment, the coil winding mold 1 includes a mold body 11 and baffles 12 detachably and fixedly disposed at two ends of the mold body 11, and the rotating shaft 2 is fixedly connected with one of the baffles 12.

For the convenience of understanding the present utility model, the following describes the working principle of the present scheme in detail with reference to fig. 1:
when the coil winding device works, one end of a copper pipeline wound on an external wire supply device (such as a wire coil) sequentially passes through the pipe expanding section 42 and the straight pipe section 41 and then is wound on one end of the surface of the die body 11 (one end of the copper pipeline can be fixed on the die body 11 or the baffle 12 by using a wire clamp if necessary), the rotation driving mechanism 3 is started, the rotation driving mechanism 3 drives the die body 11 to rotate through the rotating shaft 2 so as to wind copper pipe coils, meanwhile, the rotating shaft 2 drives the lead screw 51 to rotate through the transmission assembly 52, and the rotating lead screw 51 can drive the sliding block 9 to slide on the sliding rail 8 due to meshing transmission of the lead screw 51 and the threaded hole on the sliding block 9, so that the wire outlet pipe 4 is driven to axially move parallel to the die body 11, the copper pipeline penetrated from the straight pipe section 41 can always correspond to the winding position on the surface of the die body 11, and uneven coil winding is avoided due to the fact that the coil on the surface of the coil winding die 1 is subjected to axial pulling force.
It should be noted that, in order to avoid that the copper wire is tightened and inevitably generates a pulling force on the coil being wound, a wire feeding device may be disposed between the coil winding die 1 and the wire outlet pipe 4 or between the wire outlet pipe 4 and an external wire feeding device, and the wire feeding speed of the wire feeding device is set to be equal to the winding speed of the coil, so as to further avoid that the wound coil is pulled. Since both the wire clamp and the wire feeding device are prior art, the specific structure of the wire clamp and the wire feeding device will not be described in detail in this embodiment.
The above-described embodiments of the present utility model do not limit the scope of the present utility model. Any other corresponding changes and modifications made in accordance with the technical idea of the present utility model shall be included in the scope of the claims of the present utility model.
