Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a copper alloy rod straightening device, including two guard plates 1, each guard plate 1 having a triangular structure. A pressing shaft 3 is provided at each of the three corners of the side of the two guard plates 1 that are close to each other. The pressing shaft 3 is slidably connected to the guard plate 1 through a slider 42. The pressing shaft 3 is rotatably connected to the slider 42. An elastic element is provided inside the guard plate 1 to drive the two sliders 42 located below to move closer to each other. A connecting bracket 2 is fixedly connected to the top of the two guard plates 1. A lifting device 4 is provided on the connecting bracket 2 to drive the slider 42 located above to slide up and down.

[0023] Specifically, the guard plate 1 supports the extrusion shaft 3. The alloy rod to be straightened is placed between the three extrusion shafts 3. During straightening, the three extrusion shafts 3 rotate synchronously, and the upper extrusion shaft 3 moves downward. While rotating, it extrudes the alloy rod, which drives the alloy rod to rotate as well, thus achieving comprehensive straightening. This saves time. The elastic element allows the lower extrusion shafts 3 to move away from each other to a certain extent to avoid excessive resistance and damage to the extrusion shafts 3 when the alloy rod is bent too much during the straightening process. The lifting device 4 drives the upper extrusion shaft 3 to move downward to extrude and straighten the alloy rod.

[0024] The slider 42 has a cross-shaped structure. The guard plate 1 has a groove 13 that matches the slider 42. The elastic element includes a first spring disposed in the groove 13. The two ends of the first spring are fixedly connected to the groove 13 and the slider 42, respectively.

[0025] Specifically, the slider 42 has a cross-shaped structure, which allows it to slide on the guard plate 1 without detaching from the guard plate 1. The first spring drives the two extrusion shafts 3 below to slide closer to each other.

[0026] Two end faces of the guard plate 1 are fixedly connected to telescopic rods 11. The side of the end of the telescopic rod 11 is rotatably connected to a first transmission wheel 12. The end of the extrusion shaft 3 is fixedly connected to a second transmission wheel. A transmission device 6 is provided between the first transmission wheel 12 and the second transmission wheel. The end of the second transmission wheel is fixedly connected to a T-shaped ring block 31. The side of the slider 42 is provided with a T-shaped ring groove 421 that matches the T-shaped ring block 31.

[0027] Specifically, the telescopic rod 11 is designed to keep the transmission belt 61 taut when the extrusion shaft 3 is in the sliding adjustment position. The extrusion shaft 3 is rotatably connected to the slider 42 through the cooperation of the T-shaped ring block 31 and the T-shaped ring groove 421.

[0028] The transmission device 6 includes two transmission belts 61. One transmission belt 61 is sleeved between one of the first transmission pulleys 12, the second transmission pulley on the upper extrusion shaft 3, and the second transmission pulley on one of the lower extrusion shafts 3. The other transmission belt 61 is sleeved between the two lower extrusion shafts 3 and the other second transmission pulley.

[0029] Specifically, one transmission belt 61 is connected between one of the first transmission wheels 12, the second transmission wheel on the upper extrusion shaft 3, and the second transmission wheel on one of the lower extrusion shafts 3. The other transmission belt 61 is connected between the two lower extrusion shafts 3 and the other second transmission wheel, so that when one extrusion shaft 3 rotates, all extrusion shafts 3 can rotate synchronously.

[0030] The telescopic rod 11 includes a fixed rod 111 fixedly connected to the guard plate 1. A sliding rod 112 is fixedly connected to the end of the fixed rod 111. The end of the sliding rod 112 extends into the fixed rod 111 and is slidably connected to it. A second spring is provided inside the fixed rod 111. The two ends of the second spring are fixedly connected to the fixed rod 111 and the sliding rod 112, respectively.

[0031] Specifically, the telescopic structure of the telescopic rod 11 can change its length accordingly as the extrusion shaft 3 moves, thereby always keeping the transmission belt 61 taut, so that the extrusion shaft 3 can maintain its normal rotation no matter how it slides.

[0032] One of the protective plates 1 has a correction pipe 7 fixedly connected to its outer side, and the inside of the correction pipe 7 is connected to the inside of the protective plate 1.

[0033] Specifically, when the alloy rod passes through the correction pipe 7, the correction pipe 7 can perform preliminary correction on the alloy rod to avoid excessive bending and floating, which would affect the straightening of the extrusion shaft 3.

[0034] The lifting device 4 includes a lifting rod 41, the end of which is fixedly connected to a slider 42 located above. A T-shaped groove 21 is provided on the inner side of the connecting bracket 2, and a T-shaped block 412 matching the T-shaped groove 21 is fixedly connected to the side of the lifting rod 41.

[0035] Specifically, a drive motor 5 is fixedly installed at the top of the connecting bracket 2. The drive motor 5 is a hydraulic rod, and its output end is fixedly connected to the lifting rod 41 to provide power for the up and down movement of the lifting rod 41. The T-slot 21 and T-block 412 enable the lifting rod 41 to slide up and down stably.
