Description

Technical Field

[0001] The utility model relates to the technical field of strip steel, in particular to a rough rolling anti-warping device for hot-rolled strip steel. Background Art

[0002] In the production of strip rolling, it is necessary to enter the guide of one roughing mill from the guide of another roughing mill. During the entry process, due to the fast running speed of the strip and the thin thickness of the strip itself, the rolled piece is prone to warping. Once warping occurs, not only will the rolled piece fail to enter the guide smoothly, but it will also cause steel jamming accidents and the risk of scrap steel, affecting production efficiency. Therefore, an anti-warping device is needed to prevent the strip from warping.

[0003] Publication No.: CN209577745U discloses a strip warping prevention device, comprising an anti-warping main beam arranged along the conveying direction of the strip, with mounting cross beams installed on both sides of the top of the anti-warping main beam, and the mounting cross beams are arranged perpendicular to the anti-warping main beam; a lifting hole is provided on the top of the anti-warping main beam, and a horizontal anti-warping surface is provided in the middle of the bottom of the anti-warping main beam, and an inclined introduction surface and an inclined export surface are respectively provided on both sides of the horizontal anti-warping surface, and a continuous wear-resistant layer is provided on the horizontal anti-warping surface, the inclined introduction surface and the inclined export surface.

[0004] Currently, existing anti-warping devices have the following shortcomings: they lack an anti-scratch mechanism, and during the conveying process of the strip, they are prone to contact with the anti-warping device, causing friction and scratches on the surface, affecting the production and processing quality and results. In practice, their effectiveness is relatively poor. To address this issue, we propose a hot-rolled strip roughing anti-warping device. Summary of the Invention

[0005] The main purpose of the utility model is to provide a hot-rolled strip rough rolling anti-warping device, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A hot-rolled strip rough-rolling anti-warp device includes a shell, an anti-warp plate and an airbag cushion. The top of the shell is connected to a sleeve by bolts, the bottom of the sleeve is sleeve-connected to a sleeve rod, one end of the sleeve rod is fixedly connected to the anti-warp plate by bolts, and a notch is provided at the bottom of the anti-warp plate, in which a ball is rotatably connected.

[0008] Furthermore, a return spring is sleeved on the periphery of the sleeve rod in the sleeve, an airbag cushion is fixedly arranged on the top of the sleeve rod in the sleeve, and the sleeve is connected to one end of the airbag cushion by gluing.

[0009] Furthermore, a guide groove is provided in the anti-rocking plate at the top of the recess, and the guide groove is connected to the recess, and an oil filling hole corresponding to the guide groove is provided at the top of the anti-rocking plate.

[0010] Furthermore, air pumps are fixedly provided on both sides of the shell, the air outlet of the air pump is connected to the airbag cushion through a pipeline, and the shell is connected to the air pump through bolts.

[0011] Furthermore, a fixing seat is provided on the top of the shell, and the shell is connected to the fixing seat by welding.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The shell, anti-warp plate, notch and ball bearings are provided to prevent the strip from warping by means of extrusion limiting. At the same time, the rotation of the ball bearings can not only reduce the contact area but also reduce the friction generated during the conveying of the strip. The structure is simple and compact, the use is more reasonable and reliable, and the practical value is high.

[0014] By setting the sleeve, sleeve rod, return spring and airbag cushion, elastic deformation can be used to control and adjust the use height of the anti-warping mechanism according to the actual strip thickness, while increasing the flexibility of strip transportation. It has a simple structure, low cost and good use effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1 and 2As shown, a hot-rolled strip rough-rolled anti-warp device includes a shell 1, an anti-warp plate 4 and an airbag cushion 8. The top of the shell 1 is connected to a sleeve 2 by bolts, the bottom of the sleeve 2 is sleeved and connected to a sleeve rod 3, one end of the sleeve rod 3 is fixedly connected to the anti-warp plate 4 by bolts, and a notch 5 is opened at the bottom of the anti-warp plate 4, and a ball 6 is rotatably connected in the notch 5.

[0022] A return spring 7 is sleeved on the outer periphery of the sleeve rod 3 in the sleeve 2 , and an airbag cushion 8 is fixedly provided on the top of the sleeve rod 3 in the sleeve 2 .

[0023] In this embodiment, Figure 3 As shown, the airbag cushion 8 is deformed to push the sleeve rod 3 to slide and adjust the use height of the anti-warping mechanism, and the reset action is facilitated by the reset spring 7.

[0024] A guide groove 10 is provided at the top of the recess 5 in the anti-rocking plate 4 , and the guide groove 10 is communicated with the recess 5 . An oil filling hole 11 corresponding to the guide groove 10 is provided at the top of the anti-rocking plate 4 .

[0025] In this embodiment, Figure 4 As shown, the oil filling hole 11 facilitates the injection of lubricating oil into the guide groove 10 , thereby improving the use effect of the ball 6 in the recess 5 .

[0026] An air pump 9 is fixedly provided on both sides of the housing 1 , and an air outlet of the air pump 9 is connected to the airbag cushion 8 through a pipeline.

[0027] In this embodiment, Figure 2 As shown, the airbag cushion 8 is inflated and deformed by the air pump 9 .

[0028] A fixing seat 12 is provided on the top of the housing 1 .

[0029] In this embodiment, Figure 1 As shown, the housing 1 is conveniently fixed with bolts between the roughing mills through the fixing seat 12 .

[0030] It should be noted that the utility model is a rough rolling anti-warping device for hot-rolled strip. When working, the operator first bolts the shell 1 to be fixed between the rough rolling mills through the fixing seat 12. When the strip is sent out from the rough rolling mill, the anti-warping plate 4 can be limited to prevent the strip from warping. When the warped part of the strip contacts the anti-warping plate 4, the ball 6 is rotated to greatly reduce the friction generated by the strip, thereby preventing surface scratches. Moreover, during use, the air pump 9 can be manually turned on to inflate the airbag cushion 8 according to the actual thickness of the strip. The elastic deformation of the airbag cushion 8 is used to push the sleeve rod 3 to slide downward, thereby realizing the height adjustment of the anti-warping plate 4 to adapt to strips of different thicknesses. The structure is simple and compact, the cost is low, and it is easy to operate, and it is more flexible and stable to use.
