Description

Technical Field

[0001] The invention relates to the technical field of drawing and straightening rollers, in particular to a saving drawing and straightening roller. Background Art

[0002] The straightening roller is a device for straightening metal bars, pipes, wires, etc. The straightening machine is an important equipment in the production of cold-rolled strip steel. Under high tension conditions, the hot-rolled strip steel undergoes repeated bending and stretching by the small-diameter straightening roller of the straightening machine. Many fine cracks are generated on the surface of the iron oxide scale, which improves the pickling speed and quality. The strip steel straightened by the straightening machine becomes straighter, which is conducive to the bite of the cold rolling mill. When the straightening machine is used, the straightening roller will be used, so a kind of economical straightening roller will be used.

[0003] To this end, patent publication number CN211803728U discloses a cooling-type straightening roller. The device includes an articulated seat, on which a conveying roller component is horizontally hinged. The conveying roller component includes a horizontal rotating shaft hinged to the articulated seat and a barrel-shaped shell coaxially arranged with the horizontal rotating shaft. A water storage tank is provided on the articulated seat directly below the barrel-shaped shell. The lower end of the annular outer peripheral surface of the barrel-shaped shell is located in the water storage tank. Since the conveying roller component can fully contact the liquid in the water storage tank while rotating, it ensures that the outer peripheral surface of the conveying roller component can contact the liquid and ensures uniform cooling, thus avoiding local overheating and cracking of the conveying roller component. The device is suitable for industrial production and has strong practicality.

[0004] The above-mentioned cooling type straightening roller has a more practical effect when used, but there are still some problems: since it is inconvenient to replace both ends of the roller, both ends of the roller are more prone to wear during use, and the wear at both ends of the roller causes a large amount of consumption of the straightening roller, which reduces its life. Summary of the Invention

[0005] (1) Technical issues to be resolved

[0006] The purpose of the present invention is to provide a cost-saving straightening roller to solve the defect of the existing cooling straightening roller that it is inconvenient to replace the two ends of the roller. (2) Summary of the invention

[0008] In order to solve the above technical problems, the present invention provides the following technical solutions: an economical straightening roller, comprising a first roller body, a second roller body and a built-in cavity, wherein the outer wall of the first roller body is provided with the second roller body, and the interior of the second roller body is provided with the built-in cavity;

[0009] A cooling structure is provided inside the built-in cavity;

[0010] Both ends of the first roller body are provided with a wear-resistant structure, and the wear-resistant structure includes a third roller body, a clamping block, a support rod and a clamping groove, and the clamping groove is provided at both ends of the first roller body.

[0011] Preferably, the cooling structure includes a sealing ring, a rubber stopper, a cover body, a handle, anti-slip grooves and a sponge. The sponge is arranged inside the built-in cavity. Rubber stoppers are provided at both ends of the sponge. A sealing ring is provided on the outer wall of the rubber stopper. The cover body is fixed to one end of the rubber stopper. The handle is fixed to one end of the cover body. The outer wall of the handle is fixed with anti-slip grooves.

[0012] Preferably, the anti-slip grooves are distributed at equal intervals on the outer wall of the handle, and the inner diameter of the sealing ring is larger than the outer diameter of the rubber stopper.

[0013] Preferably, a through hole is formed in the middle of the sponge, and the outer diameter of the cover is larger than that of the rubber stopper. The cover is moved by the handle, the rubber stopper is pulled out, and cooling water is introduced through the sealing ring opening to fully absorb the cooling water into the sponge. The cover is then replaced. The sealing ring strengthens the connection between the rubber stopper and the second roller body, and the sponge fully absorbed with cooling water allows the second roller body to be cooled more evenly.

[0014] Preferably, the anti-slip pattern is designed in a circular ring shape, and the main cross-section of the sponge is designed in an "L"-shaped structure.

[0015] Preferably, a locking block is embedded in the locking groove, a third roller body is fixed to one end of the locking block, and a support rod is fixed to one end of the third roller body.

[0016] Preferably, the support rod is designed in a cylindrical structure, and the engaging block is designed in a rectangular structure.

[0017] Preferably, the outer diameter of the third roller body is larger than that of the support rod, and the engaging block and the engaging groove form an engaging structure. When the third roller bodies on either side of the second roller body have been used for a long time and are severely worn, the third roller bodies on either side of the second roller body can be removed and replaced with new ones. The square design of the engaging block and engaging groove ensures a tighter connection between the third roller body and the second roller body. Since only the third roller body is replaced, it is relatively light and can be manually replaced online.

[0018] (3) Beneficial effects

[0019] The economical straightening roller provided by the present invention has the following advantages:

[0020] By providing a wear-resistant structure, when the third rollers on both sides of the second roller are used for a long time and are severely worn, the third rollers on both sides of the second roller can be removed and replaced with new ones. The square design of the engaging blocks and engaging grooves makes the connection between the third roller and the second roller tighter. Moreover, since only the third roller is replaced, it is relatively light and can be replaced manually online without the need for a roller changing vehicle, thus saving roller changing time and improving production efficiency.

[0021] By providing a cooling structure, the cover body is driven by the handle, the rubber plug is pulled out, cooling water is put in from the sealing ring mouth, the sponge is filled with cooling water, and then the cover body is closed. The sealing ring makes the connection between the rubber plug and the second roller body closer, and the sponge filled with cooling water makes the second roller body cooled more evenly, realizing the cooling function of the device, thereby extending the service life of the energy-saving straightening roller during use.
