[0002] Copper wire is a metal material with good electrical conductivity and good thermal conductivity. As a conductor, copper wire is widely used in the manufacture of wires, cables and brushes. In the process of copper wire production and processing, in order to make the copper wire more slender, it is usually necessary to process and handle the copper wire by using a stretching device.

The outer circle of the stretching assembly is provided with copper wire. The device further comprises an electric push rod arranged in the middle of the machine body.

The inside of the cooling piece is provided with a containing cavity. The inside of the containing cavity is provided with a telescopic spring. One end of the telescopic spring is fixed on the inner wall of the cooling piece. The other end of the telescopic spring is fixedly connected with an abutting block. The part of the abutting block extending out of the containing cavity abuts against the outer wall of the copper wire. The device can cool the copper wire by sleeving the cooling piece on the copper wire and using water cooling heat transfer method.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0043] The embodiments of the present invention will now be described.

[0044] A continuous stretching device and method for tin-plated copper wire, such as Figures 1 to 12 As shown, the device includes a tensioning mechanism 1, which includes a base plate 101. A first diameter reduction plate 102 is fixedly connected to one side of the top of the base plate 101. A second diameter reduction plate 103 is fixedly connected to the side wall of the first diameter reduction plate 102. A third diameter reduction plate 104 is fixedly connected to the end of the second diameter reduction plate 103 away from the first diameter reduction plate 102. Multiple sets of diameter reduction holes 105 are coaxially formed on the side walls of the first diameter reduction plate 102, the second diameter reduction plate, and the third diameter reduction plate. The multiple sets of diameter reduction holes 105 are evenly distributed in three rows. A rotating shaft 106 is rotatably connected to the top of the base plate 101. Multiple sets of wire guide tubes 107 are fixedly sleeved on the outer wall of the rotating shaft 106. Each set of wire guide tubes 107 is aligned with a row of diameter reduction holes 105. A set of copper wires 109 is sleeved on the inner wall of each row of diameter reduction holes 105. The copper wires 109 are respectively sleeved on the outer wall of a set of wire guide spools 107. Two sets of drive motors 108 are fixedly connected to the top of the base plate 101. The output ends of the two sets of drive motors 108 are respectively fixedly connected to the two ends of the rotating shaft 106. Three sets of connecting grooves 110 are opened at the top of the base plate 101. A set of bidirectional threaded rods 111 are rotatably connected to the inner wall of each set of connecting grooves 110. Each set of bidirectional threaded rods 111 is located below a set of wire guide spools 107. Two sets of sliders 112 are threadedly connected to the outer wall of each set of bidirectional threaded rods 111. A set of pressure rollers 113 are rotatably connected to the top of each set of sliders 112. The pressure rollers 113 abut against the outer wall of the copper wires 109. Multiple sets of feeding ports 114 are opened at the bottom end of the base plate 101 away from the first diameter reduction plate 102.

[0045] The rotation of the rotating shaft 106 is driven by the motor 108, so that the rotating shaft 106 drives the wire passing barrel 107 to rotate. In the process of rotation, the copper wire 109 is wound on the outer wall of the wire passing barrel 107, so that the copper wire 109 is pulled through the reduced diameter hole 105 in the process of rotation of the wire passing barrel 107. The diameter of the reduced diameter hole 105 is smaller than the diameter of the copper wire 109, so that the copper wire 109 is stretched. In the preparation work before stretching, the two-way threaded rod 111 is rotated to increase the distance between the two groups of sliding blocks 112, so that the copper wire 109 can be more conveniently wound on the outer wall of the wire passing barrel 107. Then, the two-way threaded rod 111 is reversely rotated, so that the compression wheel 113 can press the copper wire 109 on the outer wall of the wire passing barrel 107, avoiding the slipping between the wire passing barrel 107 and the copper wire 109.

Then the pressing block 212 is pushed horizontally, the top block 216 is aligned with the limiting groove 215, at this time the top block 216 slides into the limiting groove 215 under the elastic force of the spring sheet 217. At this time the copper wire 109 is clamped by the reel 203 and the pressing block 212, so that the reel 203 can wind the copper wire 109 in the process of rotation. After the copper wire 109 is wound on the outer wall of the reel 203, the pressing rod 211 is pressed on the outer wall of the copper wire 109, so that the copper wire 109 cannot be scattered on the outer wall of the reel 203.
