[0027] like Figure 1-3 As shown, the present application provides a conveying device for a precision straightening machine for metal tubes and bars, including a bracket 1, a plurality of retaining tubes 11 are evenly distributed between the two ends of the bracket 1, and an opening 12 is provided on one side of the retaining tubes 11, so that the retaining tubes 11 are three-quarter circular, and a cover plate shaft 13 is rotatably provided on one side of one end of the bracket 1, and a plurality of cover plates 14 are fixed on one side of the cover plate shaft 13, and the position of the cover plate 14 corresponds to the position of the retaining tubes 11 located at one end of the bracket 1, and the cover plate 14 is adapted to the opening 12. An extension plate 15 is fixed on the other side of the cover plate shaft 13, and a first telescopic rod 16 is connected between the extension plate 15 and the bracket 1. In this embodiment, the first telescopic rod 16 is a hydraulic telescopic rod. The two ends of the first telescopic rod 16 are rotatably connected to the extension plate 15 and the bracket 1, respectively.

[0028] A transport device 2 is provided on one side of the retaining tube 11. The transport device 2 includes a drive shaft 21 rotatably connected to the bracket 1. A drive plate 211 is fixed on one side of the drive shaft 21. A linkage plate 212 is connected between two adjacent drive plates 211. The two ends of the linkage plate 212 are respectively rotatably connected to one drive plate 211. A second telescopic rod 213 is connected between one linkage plate 212 and the bracket 1. In this embodiment, the second telescopic rod 213 is a hydraulic telescopic rod. The two ends of the second telescopic rod 213 are respectively rotatably connected to the linkage plate 212 and the bracket 1.

[0029] Both ends of the driving shaft 21 are rotatably sleeved with shaft sleeves 22, and a rotating plate 221 is fixed on one side of the shaft sleeve 22. The upper and lower sides of the rotating plate 221 away from one end of the driving shaft 21 are rotatably connected with a conveying wheel 23 and a rotating sleeve 222 respectively. One side of the driving shaft 21 is rotatably connected with a rotating table 223 corresponding to the position of the rotating sleeve 222, and an adjusting shaft 224 is rotatably connected to the rotating table 223. The rotating sleeve 222 is sleeved on the adjusting shaft 224, and the rotating sleeve 222 is threadedly connected to the adjusting shaft 224. An elastic member 225 is fixedly connected between the rotating table 223 and the rotating sleeve 222. In this embodiment, the elastic member 225 is a spring.

[0030] A plurality of drivers 231 (only one is shown in the figure) corresponding to the position of the drive shaft 21 are fixed on one side of the bracket 1. In the present embodiment, the driver 231 is a motor. A connecting shaft 232 is connected between the output shaft of the driver 231 and one end of the conveying wheel 23. The two ends of the connecting shaft 232 are respectively connected to the output shaft of the driver 231 and one end of the conveying wheel 23 through universal joints.

[0031] It can be understood that the equipment is provided at both the entrance and the exit of the straightening machine, and is used to transport the bars to the straightening machine and to transport the processed bars out of the straightening machine, respectively.

[0032] Specifically, the extension and retraction of the second telescopic rod 213 can drive the drive plate 211 connected thereto to rotate, thereby rotating the drive shaft 21. Since the drive plates 211 are connected with the linkage plates 212, the linkage plates 212 can make all the drive plates 211 move synchronously. Therefore, the extension and retraction of the second telescopic rod 213 can drive all the drive shafts 21 to rotate.

[0033] The rotating sleeve 222 is threadedly connected with the adjusting shaft 224, so that the driving shaft 21 and the sleeve 22 are fixed. Therefore, when the second telescopic rod 213 is extended, the rotation of the driving shaft 21 will drive the rotating plate 221 to tilt up, thereby increasing the height of all the conveying wheels 23. When the second telescopic rod 213 is shortened, the rotating plate 221 will droop, reducing the height of all the conveying wheels 23. In summary, the effect of synchronously increasing and reducing the height of all the conveying wheels 23 is achieved. On the one hand, the angle changes of all the rotating plates 221 are the same. When the initial heights of the conveying wheels 23 are consistent, the heights of the conveying wheels 23 after the second telescopic rod 213 is extended and retracted are still consistent, thereby ensuring that the rods are supported stably during transportation and avoiding the problem of rod bending caused by unstable support; on the other hand, the height of the rods can be adjusted by adjusting the height of the conveying wheels 23, which is convenient for the rods to align with the processing position of the straightening machine, and enables the conveying device to adapt to rods of different diameters.

[0034] After the position of the conveying wheel 23 is changed by the connecting shaft 232 , the driver 231 can still drive the conveying wheel 23 to rotate, thereby conveying the rods.

[0035] When the rods are not being processed, the rotating sleeve 222 can be moved on the adjusting shaft 224 by rotating the adjusting shaft 224, and then the rotating plate 221 can be rotated relative to the driving shaft 21, so as to adjust the initial height of the conveying wheel 23. On the one hand, it is convenient to adjust the conveying wheel 23 when the initial height is inconsistent during use, so as to correct the unstable support during the transportation of the rods in time and reduce losses; on the other hand, it avoids the trouble of constantly detecting and confirming the initial height of each conveying wheel 23 during assembly. During assembly, it is possible to ensure that the initial heights of the conveying wheels 23 are roughly the same, and then adjust them to the same initial heights after assembly, thereby reducing the trouble of assembling the equipment.

[0036] The elastic member 225 is used to pull the rotating platform 223 and the rotating sleeve 222 closer to each other through its own elasticity, thereby eliminating the thread gap between the rotating sleeve 222 and the adjusting shaft 224, and ensuring that the height of the conveying wheel 23 is accurately adjusted.

[0037] The end of the bracket 1 provided with the cover plate 14 will face the straightening machine. The cover plate shaft 13 can be driven to rotate by the extension and retraction of the first telescopic rod 16, so that the cover plate 14 is tilted, thereby opening the opening 12.

[0038] For shorter bars, it is not necessary to open the cover plate 14, and the bar can be placed in the retaining tube 11 as a whole through the opening 12 of the retaining tube 11 without the cover plate 14. For longer bars, it is necessary to open the cover plate 14 first, and let the cover plate 14 avoid the bar. After the bar is placed in the retaining tube 11 as a whole, the retaining tube 11 is covered. In summary, the effect of conveniently placing the bar into the retaining tube 11 from the side is achieved, avoiding the trouble of reserving a large space at one end of the conveying device for storing and accessing the bar, and achieving the effect of reducing the space occupied area.

[0039] The opening 12 on the side close to the straightening machine is covered by a cover plate 14. During the interweaving of the bars, when high-temperature treatment and high-speed rotation are performed, flying objects will be blocked by the cover plate 14 and the blocking tube 11, ensuring the safety of the processing.
