Description

Technical Field

[0001] This utility model relates to the field of seamless steel pipe processing technology, and more specifically to a pipe feeding device for seamless steel pipe processing. Background Technology

[0002] In modern industrial production systems, seamless steel pipes, due to their superior performance characteristics, have become an indispensable basic material in many fields such as construction, machinery, and energy. In modern steel pipe processing technology, the straightening process is a crucial step in ensuring the straightness of the pipe, and its operational precision directly affects the quality of the final product. It is worth noting that when the steel pipe to be processed is transported to the straightening equipment, it usually requires the use of a specialized pipe clamping device to achieve precise clamping and directional transport. This technical step plays a decisive role in ensuring the subsequent straightening effect.

[0003] For example, patent document CN219075431U discloses an adjustable clamping and pushing device for seamless steel pipe processing. This device aims to solve the technical problem that current seamless steel pipe processing often suffers from horizontal swaying due to end force during feeding, leading to reduced processing accuracy. The device includes a worktable, support platforms symmetrically arranged above the worktable, clamping platforms symmetrically arranged above the worktable, and a balance platform located on the front side above the worktable. The adjustable clamping and pushing device uses a vertically lifting support platform in conjunction with the clamping platform to lock the seamless steel pipe to be processed within an enclosing groove, restricting its horizontal movement and maintaining axial transport during the pushing process. This allows the processing equipment to accurately act on the surface of the seamless steel pipe. A linear motor drives the balance platform and the pushing back plate to move horizontally, ensuring that the force applied to the end of the seamless steel pipe during feeding is consistent in direction, thus improving the pushing stability of the seamless steel pipe.

[0004] However, this device has the following drawbacks: for steel pipes with a slightly larger ellipticity, uneven force during clamping and conveying may cause slight deformation of the pipe or aggravate surface damage. Utility Model Content

The first lead screw 203 is threadedly connected to the slider 204. The support plate 201 is fixedly connected to the side of the slider 204 away from the first motor 205.

[0030] With the help of a precisely designed power transmission mechanism, the transmission system enables the support plate 201 to move axially in a stable manner, so that the support plate 201 can reach a suitable height to support the seamless steel pipe.

[0031] Reference Figure 2 The transmission assembly 3 includes a second motor 301, a second lead screw 302, and a first slide 303; the first slide 303 is fixedly connected above the worktable 1; the first slide 303 is located between the inner sides of the support plate 201; the second lead screw 302 moves through the first slide 303; the second motor 301 is fixedly connected to the side of the second lead screw 302 away from the straightening assembly 5.

[0032] This transmission system enables the clamping assembly 4 to clamp the steel pipe and make stable axial movements. This design ensures both effective transport of the steel pipe and stable operation of the system.

[0033] Reference Figure 1 and Figure 3 The straightening assembly 5 includes a second cylinder 501, a housing 502, a stamping block 503, and a pad 504. The housing 502 is fixedly connected to the upper part of the worktable 1 away from the support assembly 2. The second cylinder 501 is fixedly connected to the upper part of the housing 502. The piston of the second cylinder 501 is fixedly connected to the stamping block 503. The stamping blocks 503 are symmetrically distributed. The pad 504 is fixedly connected to the inner bottom of the housing 502. The stamping block 503 is fixedly connected to the side of the pad 504 near the second cylinder 501.

[0034] The straightening system uses a pneumatic transmission device as a power source. By precisely controlling the reciprocating motion of the cylinder, radial pressure is applied to the seamless steel pipe, thereby straightening the steel pipe.

[0035] The working principle of this utility model is as follows: When support for the steel pipe is required, the first motor 205 is started first. The first motor 205 drives the synchronous pulley 207 to rotate, which in turn drives the synchronous belt 206 meshing with it, causing the other synchronous pulley 207 to rotate accordingly. The synchronous pulley 207 then drives the first lead screw 203 fixedly connected to it. The rotation of the first lead screw 203 causes the slider 204, which is threadedly connected to it, to move axially. The slider 204 drives the support plate 201 fixedly connected to it to move axially, thereby allowing the support plate 201 to reach a suitable height and achieve support for the seamless steel pipe.

[0036] When it is necessary to clamp the seamless steel pipe, the first cylinder 403 is activated. The first cylinder 403 drives the connecting block 404 to move forward, and the connecting block 404 in turn drives the movable plate 405, which is movably engaged with it. Since both ends of the movable plate 405 are movably engaged with the connecting block 404 and the moving block 408 respectively, when the connecting block 404 moves axially, the movable plate 405 can drive the moving block 408, so that the whole can extend or expand, thereby achieving the effect of clamping the seamless steel pipe.

[0037] When it is necessary to transport seamless steel pipes, the second motor 301 is started, which drives the second lead screw 302 to rotate, thereby enabling the slide plate 413, which is threadedly connected to the second lead screw 302, to move axially along the slide rail and send the steel pipe into the straightening assembly 5.

[0038] When it is necessary to straighten the seamless steel pipe, the second cylinder 501 is activated. The operation of the second cylinder 501 will drive the stamping block 503 to move downward. Through the cooperation between the stamping blocks 503, the seamless steel pipe is struck, thereby achieving the straightening effect.
