Technical Field
[0001] The utility model relates to the field of seamless steel pipe processing, in particular to a high-precision thick-wall seamless steel pipe forming device. Background Art
[0002] Thick-walled seamless steel pipe is a type of steel pipe characterized by its thick wall, typically produced through a hot rolling process. With a wall-thickness-to-diameter ratio of less than 20, this type of pipe is primarily used in various applications, including machining, coal mining, and hydraulic steel. Large-diameter, thick-walled seamless steel pipe plays a vital role in my country's steel pipe industry, with widespread applications in oil and gas drilling, petrochemicals, boilers, bearings, automobiles, tractors, and aviation. During production, thick-walled seamless steel pipe undergoes hot rolling.
[0003] Existing seamless steel pipe forming devices, such as authorization announcement No. CN219025409U3, disclose a hot rolling forming device for stainless steel seamless steel pipes. By starting the first motor, the rotating shaft is driven to rotate, and the threaded cylinder is driven to rotate through the active bevel gear and the driven bevel gear. Therefore, under the sliding limit action of the limit shaft, the threaded rod can drive the clamping plate to move, thereby clamping the seamless steel pipe. It can be applied to stainless steel seamless steel pipes of different sizes, but it requires synchronous control of the two first motors located in the connecting drum to keep the seamless steel pipe clamped in the center, which is more troublesome. Moreover, when the connecting drum rotates, the first motor inside it rotates synchronously, which makes it inconvenient to perform wiring operations on the first motor. Utility Model Content

[0022] The utility model is described in further detail below:

[0024] The seamless steel pipe to be processed is placed inside the fixed sleeve 41, and the driving motor 411 is controlled to drive the driving gear 410 on the rotating shaft 49 to rotate, and the driving gear 410 drives the gear ring 43 to rotate. When the gear ring 43 rotates, the thread groove 44 on the front side thereof is synchronously driven to rotate, and the clamping rod 46 is engaged with the front side of the thread groove 44 by the card teeth 47, thereby driving the clamping rods 46 on the upper and lower sides to slide inward along the limit card slots 45, thereby clamping the seamless steel pipe between the sleeve rollers 57. It is suitable for thick-walled seamless steel pipes of different sizes and is easy to control and operate.
[0025] like Figure 5 As shown, the rotating assembly 5 includes a cylinder 51, which is fixedly mounted at the rear of the top of the mounting plate 2, and a mounting block 52 is fixedly connected to the bottom of the cylinder 51. A second rotating shaft 53 and a third rotating shaft 54 are movably mounted on the inner side of the mounting block 52, and a gear set 55 is fixedly mounted on the outside of the second rotating shaft 53 and the third rotating shaft 54. A second driving motor 56 connected to the second rotating shaft 53 is fixedly mounted on the rear side of the mounting block 52, and a sleeve roller 57 is fixedly mounted on the outside of the third rotating shaft 54.
[0026] By controlling the cylinder 51 to drive the mounting block 52 downward, the sleeve roller 57 is pressed against the outer wall of the seamless steel pipe, and by controlling the driving motor 2 56 to drive the rotating shaft 2 53 to rotate, the gear set 55 between the rotating shaft 2 53 and the rotating shaft 3 54 drives the rotating shaft 3 54 to rotate, and the rotation of the rotating shaft 3 54 drives the sleeve roller 57 to rotate, and the seamless steel pipe is driven to rotate by the sleeve roller 57, thereby facilitating the rotation of the thick-walled seamless steel pipe and facilitating wiring use.
[0027] like Figure 3 As shown, a driving motor 411 is fixedly mounted on the rear side of the mounting plate 2 and is transmission-connected to a rotating shaft 49.
[0028] The driving motor 1 411 is installed on the rear side of the mounting plate 2, and a reduction gear is provided between the driving motor 1 411 and the rotating shaft 1 49, so that the driving motor 1 411 drives the rotating shaft 1 49 to rotate and drives the driving gear 410 to rotate.
[0029] like Figure 3 As shown, a bearing ring is movably installed between the fixed sleeve 41 and the gear ring 43.
[0030] By arranging a bearing ring between the fixing sleeve 41 and the gear ring 43 , the friction of the gear ring 43 is reduced.
[0031] like Figure 1 and Figure 2 As shown, the limiting bayonet 45 and the clamping rod 46 are both located on the front side of the mounting plate 2 .
[0032] The position-limiting bayonet 45 and the clamping rod 46 are located at the front side of the mounting plate 2 , thereby preventing the clamping rod 46 from moving outward along the position-limiting bayonet 45 and being blocked by the mounting plate 2 , thereby ensuring stable use.

[0034] The provision of the opening facilitates the meshing transmission between the driving gear 410 and the gear ring 43 .
[0035] like Figure 1 and Figure 4 As shown, a supporting roller 412 is movably mounted on the inner side of the latching tooth 47 and is symmetrically arranged on the left and right.
[0036] The mounting block 52 is disposed on the rear side of the mounting plate 2 .
[0037] By setting the support roller 412, the seamless steel pipe is located inside the support roller 412, so that the support roller 412 rolls when the seamless steel pipe rotates, reducing friction and facilitating operation.
[0038] The following is a detailed description of the working principle of the high-precision thick-walled seamless steel pipe forming device.
[0039] like Figures 1 to 5 As shown, the seamless steel pipe to be processed is placed on the inner side of the fixed sleeve 41 above the lower latching teeth 47, and then the driving motor 1 411 installed on the rear side of the mounting plate 2 is started by control. The driving motor 1 411 and the rotating shaft 1 49 are used to transmit the power to the driving gear 410 on the rotating shaft 1 49, and the driving gear 410 drives the gear ring 43 engaged with it to rotate. When the gear ring 43 rotates, the thread groove 44 on the front side thereof is synchronously driven to move, and the clamping rod 46 is engaged with the latching teeth 47 on the front side of the thread groove 44, thereby driving the clamping rods 46 on the upper and lower sides to slide inward along the limit bayonet 45. , thereby clamping the seamless steel pipe between the rollers 57, which can be adjusted according to the seamless steel pipe. When the clamped seamless steel pipe needs to be rotated, the mounting block 52 is driven downward by controlling the cylinder 51 to make the roller 57 rest against the outer wall of the seamless steel pipe. Since the support roller 412 is set on the inner side of the clamping tooth 47, the seamless steel pipe is located on the inner side of the support roller 412. The second shaft 53 is driven to rotate by controlling the driving motor 2 56, and the shaft 3 54 is driven to rotate by the gear set 55 between the shaft 2 53 and the shaft 3 54. The roller 57 is driven to rotate by the rotation of the shaft 3 54, and the seamless steel pipe is rotated by the roller 57.
[0040] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
