Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe processing, in particular to a rolling forming processing mechanism for corrosion-resistant steel pipes. Background Technique

[0002] A rolling mill consists of two or more rollers arranged in a certain form and can be divided into cold rolling and hot rolling. According to the number of rollers, rolling mills can be divided into two-roller, three-roller, four-roller, and five-roller rolling mills, etc. When producing large-diameter steel pipes, they need to be rolled and formed by a rolling mill. When the rolling mill rolls a steel pipe, the thickness of the steel pipe wall can be adjusted through a force control mechanism.

[0003] For example, in the Chinese patent with the application number "CN202123378475.9" and the name "A force control mechanism during the rolling forming process of corrosion-resistant steel pipes", it includes a support frame and a chute. A driving mechanism is installed on the side of the support frame. Among them, a driving wheel is installed between the support frame and the driving mechanism. An adjustment groove is opened on the side of the support frame. An adjustment block is slidably connected inside the adjustment groove. A driven wheel is connected between the adjustment blocks. A push cylinder is connected to the top of the adjustment block. In this force control mechanism during the rolling forming process of corrosion-resistant steel pipes, when rotating the nut, it can slide in a threaded manner through the bolt. When the nut slides in a threaded manner, it will be separated from the connecting block. Pulling the cover plate can drive the connecting block to move. When the connecting block moves, it can drive the chute to move. When the chute moves, it can slide through the bolt. When the cover plate moves, it can be flipped with the support frame through a hinge. When the cover plate flips, it can open the operation groove for maintenance, facilitating the operation groove to be opened for maintenance.

[0004] However, this device has certain limitations during rolling. It cannot limit the position of steel pipes with different radii, and at the same time, the steel pipe will shift during the rolling process, thus affecting the rolling effect of the steel pipe. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a rolling forming processing mechanism for corrosion-resistant steel pipes. By setting a first limiting device and a second limiting device, it is convenient to limit and guide the steel pipe before rolling, so that the steel pipe remains stable during the rolling process, thereby improving the rolling effect of the steel pipe.

The role of the drawings is to supplement the description of the text part of the specification, enabling people to visually and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be construed as a limitation on the protection scope of the present utility model.

[0022] Refer to Figures 1-4, an embossing and forming processing mechanism for a corrosion-resistant steel pipe in an embodiment of the present utility model, which includes: a workbench 1, a support frame 2 is fixedly connected above the workbench 1, a first motor 3 is fixedly connected to one side of the support frame 2, and an output end of the first motor 3 is fixedly connected to a roller 4. The roller 4 rotates through the output of the first motor 3. Both sides of the inner wall of the support frame 2 are provided with groove bodies 5. Second motors 6 are fixedly connected to the front and rear sides above the support frame 2. Output ends of the second motors 6 are fixedly connected to lead screws 7. A moving block 8 is sleeved on the outer side of the lead screw 7. The lead screw 7 is output by the second motor 6 to drive the moving block 8 to slide on the inner wall of the groove body 5. Opposite sides of the moving block 8 are fixedly connected with connecting blocks 9. A lower inner wall of the connecting block 9 is rotatably connected with a pressure roller 10. The moving block 8 slides to drive the connecting block 9 to move up and down, so that the pressure roller 10 cooperates with the roller 4 to emboss the steel pipe. A first limiting device 11 and a second limiting device 12 are arranged above the workbench 1 and on one side of the support frame 2.

[0023] The first limiting device 11 includes columns 111 fixedly connected to the front and rear sides above the workbench 1. A chute 112 is arranged on opposite sides of the columns 111. A slider 113 is slidably connected to the inner wall of the chute 112. An upper guide wheel 114 is rotatably connected to opposite sides of the slider 113. A lower guide wheel 115 is rotatably connected to opposite sides of the columns 111 and below the upper guide wheel 114. The surfaces of the upper guide wheel 114 and the lower guide wheel 115 are smooth surfaces. The upper guide wheel 114 cooperates with the lower guide wheel 115 to limit the upper and lower ends of steel pipes with different radii.

[0024] The second limiting device 12 includes positioning plates 121 fixedly connected to the front and rear sides above the workbench 1. A bolt 122 is threadedly connected to one side of the positioning plate 121. A handle 123 is fixedly connected to one end of the bolt 122. A bracket 124 is fixedly connected to the end of the bolt 122 away from the handle 123. A transverse guide wheel 125 is rotatably connected to the inner wall of the bracket 124. By rotating the handle 123, it is convenient to drive the transverse guide wheel 125 at one end of the bolt 122 to limit the front and rear sides of the steel pipe.

[0025] Working principle: When used for the first time, one end of the steel pipe is introduced between the upper guide wheel 114 and the lower guide wheel 115. The upper guide wheel 114 and the lower guide wheel 115 cooperate to limit the upper and lower ends of the steel pipe. When facing steel pipes with different radii, the position of the slider 113 inside the chute 112 can be adjusted by rotating the limit screw 1111, so that the slider 113 drives the upper guide wheel 114 to move up and down, facilitating the limitation of the upper and lower ends of the steel pipe. At the same time, during the process of conveying the steel pipe, the handle 123 can be rotated to drive one end of the bolt 122 and the bracket 124 to move towards both sides of the steel pipe, so that the horizontal guide wheel 125 limits the front and rear sides of the steel pipe. When rolling the steel pipe, according to the radius of the steel pipe, the second motor 6 can be started to output the lead screw 7 to drive the moving block 8 to slide on the inner wall of the groove body 5. The sliding of the moving block 8 drives the connecting block 9 to move up and down, so that the pressing roller 10 and the roller 4 cooperate to roll the steel pipe.

[0026] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field to which the present invention pertains, various changes can be made without departing from the gist of the present invention.
