Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 3The utility model provides a cable anti-breaking wire automatic straightening copper wire drawing device, including a device body 1, a feed port 2 is opened on the left side wall of the device body 1, and the copper wire raw material enters the device body 1 through the feed port 2. The inner wall of the device body 1 is slidably connected with a slider 3, and the inner end of the slider 3 is fixedly connected with a central axis 4. The outer wall of the central axis 4 passes through and is rotatably connected with a wire drawing wheel 5. After the copper wire raw material enters the device body 1, it is wound on multiple groups of wire drawing wheels 5 for straightening. The outer wall of the slider 3 is slidably connected to the inner wall of the device body 1, and the outer wall of the slider 3 is set The circular protrusion structure can be stuck in the inner wall of the device body 1 to make it more stable, and slides along the inner wall of the device body 1 with the slider 3. The sliding of the slider 3 can change the distance between the drawing wheels 5, adjust the friction force, adjust the friction force according to the different specifications of the raw materials, and prevent the raw materials from breaking. The inner wall of the slider 3 is elastically connected with a buckle assembly through a reset spring a6. The buckle assembly includes a clamping block a7. One end of the reset spring a6 is fixedly connected to the bottom end of the clamping block a7, and the other end of the reset spring a6 is slidably connected to the inner wall of the slider 3. Press down The pressing block a7 can squeeze the reset spring a6 to move downward. At the same time, the elastic force generated by the deformation of the reset spring a6 gives the block a7 an upward thrust to reset it. The outer wall of the device body 1 is provided with a plurality of groups of slots 8. The outer wall of the block a7 is engaged with the inner wall of the slot 8. After the block a7 is pressed inward until it is completely immersed in the groove of the slider 3, the engagement with the slot 8 is released. At this time, the slider 3 can be moved to slide along the slide groove of the device body 1, driving the distance between the wire drawing wheels 5 to change, thereby adjusting the friction force. The inner wall of the device body 1 is provided with a plurality of groups of circular grooves 9 The inner wall of the circular groove 9 is detachably connected with a cylindrical block 10, and the inner end of the cylindrical block 10 is fixedly connected with a mold 14. The diameter of the mold 14 gradually narrows from wide. After the copper wire raw material is straightened, it passes through the mold 14 and gradually becomes thinner, and finally extends out from the notch at the right end of the equipment body 1. The outer wall of the equipment body 1 is fixedly connected with a motor 15, and a winding roller 16 is fixedly connected to the output shaft of the motor 15. After the copper wire comes out from the inside of the equipment body 1, it is wound on the winding roller 16.

[0025] See also Figure 2 and Figure 4The inner wall of the columnar block 10 is slidably connected with a pull rod 13, and the inner wall of the pull rod 13 is slidably connected with two groups of card blocks b11. The interval between the two groups of card blocks b11 is elastically connected by a reset spring b12. The two ends of the reset spring b12 are respectively fixedly connected to the inner end of the two groups of card blocks b11. Pressing the two groups of card blocks b11 inward can squeeze the reset spring b12 to shrink inward. At the same time, the elastic force generated by the deformation of the reset spring b12 gives the two groups of card blocks b11 an outward thrust to reset them. The side wall of the card block b11 contacts the inner wall of the columnar block 10, and the side wall of the right end of the card block b11 Half of it is a flat surface and the other half is an inclined surface. Under normal circumstances, the flat surface of the right end of the block b11 abuts against the inner wall of the columnar block 10. When the columnar block 10 needs to be removed from the circular groove 9, the block b11 is pressed inward to press the flat part into the groove of the pull rod 13. Then the pull rod 13 is pulled outward, and the columnar block 10 squeezes the inclined surface of the block b11 to assist its contraction until the side wall of the block b11 on the outside contacts the inner wall of the columnar block 10, abutting it and making it unable to be reset. At this time, the columnar block 10 and the mold 14 can be disassembled for replacement or maintenance, and the right end of the block b11 is clamped with the outer wall of the device body 1. The block b11 clamps the outer wall of the device body 1 to prevent the mold 14 from falling off.

[0026] Working principle: Put the copper wire raw material into the equipment body 1 through the feed port 2, wrap it around multiple sets of drawing wheels 5 to straighten it, and then pass it through multiple sets of dies 14 to gradually draw it thinner and finally take it up by the winding roller 16. When the friction force needs to be adjusted by adjusting the distance between the drawing wheels 5, press the block a7 inward to press it into the slider 3, and then slide the slider 3 to adjust the position of the drawing wheel 5. After the adjustment is completed, let go, and the reset spring a6 pushes the block a7 into the slot 8 to fix it. If it is damaged, When the mold 14 needs to be replaced or its position needs to be adjusted to cope with the change in the interval between the drawing wheels 5, the block b11 is pressed inward and then the pull rod 13 is pulled outward to drive the block b11 to squeeze the reset spring b12 and retract it. After that, the cylindrical block 10 together with the mold 14 can be removed from the circular groove 9. The disassembly is convenient and no additional disassembly tools are required. After reinstalling it into the circular groove 9, the pull rod 13 is pressed inward, and the reset spring b12 will push the block b11 out to clamp the surface of the device body 1 and fix it.
