After long-term use, the internal mechanical parts often need to be disassembled for repair and maintenance. For devices that are inconvenient to disassemble, it is time-consuming and laborious during repair and maintenance. Therefore, further improvement is needed. Content of the Utility Model

[0005] The utility model provides a production device for cold-hard steel pipes, which solves the problems in the related technologies that the traditional steel pipe production devices generally cannot perform cold rolling processing on steel pipes, so as to make the outer diameter of the pipe billets consistent and eliminate defects, and the fixed devices are not easy to disassemble for the repair and maintenance of their internal mechanical parts.

[0006] The technical solution of the utility model is as follows:

[0007] A production device for cold-hard steel pipes includes a device main body. A limiter is arranged at the top of the device main body. Two cylinders are arranged inside the device main body. Support plates are fixedly connected to the bottoms of the two cylinders. The cylinders are fixedly connected with a moving seat through telescopic rods. A rack is fixedly connected inside the device main body. A second gear is connected to the outer side of the moving seat through a bearing. The second gear meshes with the rack. A first gear is also connected to the outer side of the moving seat through a bearing. The first gear meshes with the second gear. The two side walls of the inner cavity of the moving seat are connected with a first rolling roll through bearings. The two side walls of the inner cavity of the moving seat are also connected with a second rolling roll through bearings. A sliding rail is fixedly connected to the bottom of the limiter. Four connecting rods are also fixedly connected to the bottom of the limiter.

[0008] Preferably, the two support plates are fixedly connected to the inner wall of the device main body, and the first rolling roll is fixedly connected to the first gear.

[0009] Preferably, a fixed connection is provided between the second gear and the second roller, and all four connecting rods are in contact with the top of the device body.

[0010] Preferably, the sliding rail is in contact with the outside of the first roller, and the moving seat is in contact with the inside of the device body.

[0011] Preferably, two fixing plates are fixedly connected to the bottom of the connecting rod, and a clamping plate is movably connected between the two fixing plates through a rotating shaft.

[0012] Preferably, a connecting plate is fixedly connected to the bottom of the connecting rod, a first spring is fixedly connected to one side of the connecting plate, and the clamping plate is fixedly connected to the first spring.

[0015] The working principle and beneficial effects of the present utility model are as follows:

[0016] In the present utility model, when the first gear rotates and moves, it will drive the first roller to rotate and move along the inside of the sliding rail. At this time, while the first roller and the second roller reciprocate and move, they will also rotate, enabling cold rolling processing on the outside of the tube blank. By driving the first roller and the second roller to reciprocate and rotate through two cylinders, the outside of the tube blank can be quickly cold-rolled, eliminating the bamboo joint-like defects. This solves the problems of traditional steel pipe production devices that generally cannot perform cold rolling processing on steel pipes, resulting in inconsistent outer diameters of the tube blanks and defects, and the fact that fixed devices are not convenient for disassembly and maintenance of their internal mechanical parts.

[0017] In the present utility model, the limitation of the sliding rail 11 on the first roller 7 will also disappear. At this time, the staff can disassemble the first roller 7 and the second roller 8 for maintenance and replacement. Through the above device, it is convenient for the staff to quickly disassemble the limiter 2, thereby releasing the limiting fixation of the sliding rail 11 on the first roller 7, facilitating the disassembly, maintenance, and replacement of the first roller 7 and the second roller 8. This solves the problems of traditional steel pipe production devices that generally cannot perform cold rolling processing on steel pipes, resulting in inconsistent outer diameters of the tube blanks and defects, and the fact that fixed devices are not convenient for disassembly and maintenance of their internal mechanical parts.

[0027] Embodiment 1

[0028] As Figures 1 to 3As shown, this embodiment proposes a production device for cold-hardened steel pipes, including a device body 1, a limiter 2 is provided on the top of the device body 1, two cylinders 3 are provided inside the device body 1, the bottoms of the two cylinders 3 are fixedly connected to a support plate 4, the cylinder 3 is fixedly connected to a moving seat 6 through a telescopic rod, the inside of the device body 1 is fixedly connected to a rack 5, the outer side of the moving seat 6 is connected to a gear 2 10 through a bearing, the gear 2 10 is meshed with the rack 5, the outer side of the moving seat 6 is also connected to a gear 1 9 through a bearing, the gear 1 9 is meshed with the gear 2 10, the inner side walls of the inner cavity of the moving seat 6 are connected to rollers 1 7 through bearings, the inner side walls of the moving seat 6 are also connected to rollers 2 8 through bearings, the bottom of the limiter 2 is fixedly connected to a sliding rail 11, and the bottom of the limiter 2 is also fixedly connected to four connecting rods 12.

[0029] In this embodiment, the two support plates 4 are fixedly connected to the inner wall of the device body 1, and the roller 7 is fixedly connected to the gear 9, so that the gear 9 can rotate and drive the roller 7 to rotate at the same time.

[0030] In this embodiment, the second gear 10 is fixedly connected to the second roller 8, and the four connecting rods 12 are in contact with the top of the device body 1, so that the second gear 10 can rotate and drive the second roller 8 to rotate at the same time.

[0031] In this embodiment, the sliding rail 11 is in contact with the outside of the roller 7, and the moving seat 6 is in contact with the inside of the device body 1, which can facilitate the roller 7 to rotate and move along the inside of the sliding rail 11.

[0032] When in use, the staff first places the tube embryo between roller 1 7 and roller 2 8 through the inside of the device body 1, and performs cold rolling to make the outer diameter of the tube embryo consistent to eliminate bamboo-like defects. At this time, the staff starts the two cylinders 3. When the cylinder 3 is started, the movable seat 6 will be driven to move through the telescopic rod. When the movable seat 6 moves, it will drive the gear 2 10 to rotate and move along the rack 5. When the gear 2 10 rotates and moves, it will drive the roller 2 8 to rotate and move. When the gear 2 10 rotates and moves, it will also drive the gear 1 9 to rotate and move. When the gear 10 rotates and moves, it will also drive the gear 1 9 to rotate and move. When the gear 1 9 rotates and moves, it will drive the roller 1 7 to rotate and move along the inside of the sliding rail 11. At this time, the roller 1 7 and the roller 2 8 reciprocate and rotate at the same time, so that it can perform cold rolling on the outside of the tube embryo. The two cylinders 3 drive the roller 1 7 and the roller 2 8 to reciprocate and rotate, so that the outside of the tube embryo can be quickly cold rolled to eliminate bamboo-like defects.

[0033] Example 2

[0034] like Figures 3 to 6As shown in the figure, based on the same concept as in the above-mentioned Embodiment 1, this embodiment also proposes that two fixing plates 13 are fixedly connected to the bottom of the connecting rod 12, and a clamping plate 14 is movably connected between the two fixing plates 13 through a rotating shaft.

[0035] In this embodiment, a connecting plate 15 is fixedly connected to the bottom of the connecting rod 12, a first spring 16 is fixedly connected to one side of the connecting plate 15, and the clamping plate 14 is fixedly connected to the first spring 16, which can facilitate the compression of the first spring 16 while the clamping plate 14 is stressed.

[0036] In this embodiment, four connecting grooves 17 are opened inside the device main body 1. The connecting grooves 17 are in contact with the clamping plate 14, and the connecting grooves 17 are also in contact with the connecting plate 15.

[0037] In this embodiment, one end of a plurality of second springs 18 is fixedly connected to a push plate 19, and a long plate 20 is fixedly connected to one side of each of the two push plates 19. The long plate 20 is in contact with one side of the clamping plate 14, and the long plate 20 is in contact with the inside of the connecting groove 17, which can facilitate the rotation of the clamping plate 14 into the inside of the connecting groove 17 when the long plate 20 moves.

[0038] When maintenance and repair are required for the first roller 7 and the second roller 8, the staff first push the two push plates 19 into the inside of the connecting grooves 17 respectively. When the two push plates 19 move, they will drive the two long plates 20 to move. When the long plates 20 move, they will drive a plurality of second springs 18 to compress. When the long plates 20 move, they will also drive one side of the two clamping plates 14 to be stressed and rotate into the inside of the two connecting grooves 17. At this time, when the clamping plate 14 is stressed, it will also drive the first spring 16 to compress. When one side of the clamping plate 14 rotates into the inside of the connecting groove 17, the staff can then remove the limiter 2. At the same time, the limit of the sliding rail 11 on the first roller 7 will also disappear. At this time, the staff can disassemble, maintain and replace the first roller 7 and the second roller 8. Through the above device, it is convenient for the staff to quickly disassemble the limiter 2, thereby releasing the limit fixation of the sliding rail 11 on the first roller 7, and thus facilitating the disassembly, maintenance and replacement of the first roller 7 and the second roller 8.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
