Description

Technical Field

[0001] This utility model relates to the field of metal processing equipment technology, and in particular to a high-wire horizontal loose-sleeve pressure roller device with an inlaid tungsten carbide roller ring wear-resistant sleeve. Background Technology

[0002] In high-speed wire rod production, the horizontal looper device is used to adjust the tension of the rolled piece, and its core component is the looper pressure roller. In existing technologies, the horizontal looper pressure roller mostly adopts an integral structural design, such as... Figure 1 As shown, its roller body is made of a single material, such as high carbon steel or alloy steel. The main function of such pressure rollers is to provide rolling support after the workpiece is unrolled.

[0003] Because the pressure roller is a single piece, once the wear-resistant points are worn out, the whole thing cannot be reused and must be scrapped, resulting in a waste of resources. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a high-wire horizontal slip-on pressure roller device with embedded tungsten carbide roller ring wear-resistant sleeve, which aims to solve the problem that the pressure roller with an integral structure can only be scrapped as a whole after the wear-resistant points are worn, resulting in resource waste.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a high-wire horizontal loose-sleeve pressure roller device with an embedded tungsten carbide roller ring and wear-resistant sleeve, including a pressure roller base and a wear-resistant sleeve. The wear-resistant sleeve is fitted onto the pressure roller base, and the wear-resistant sleeve and the pressure roller base are detachably connected. A locking component is installed on the top of the pressure roller base. Because the wear-resistant sleeve and the pressure roller base are detachably connected, once the wear points are worn, the wear-resistant sleeve can be replaced individually, without the need to scrap the entire pressure roller, thus solving the resource waste problem of traditional pressure rollers.

[0006] As a further improvement of this utility model: the wear-resistant insert and the pressure roller base are interference-fitted. This interference fit allows for mechanical installation of the wear-resistant insert and the pressure roller base, enabling individual replacement of the wear-resistant insert and reducing energy consumption.

[0010] As a further improvement of this utility model: the wear-resistant insert adopts a tungsten carbide roller ring. By using a tungsten carbide roller ring for the wear-resistant insert, the tungsten carbide material has high hardness and wear resistance superior to traditional roller materials; the wear resistance cycle of the tungsten carbide roller ring has been increased from the original steel throughput of 20,000 tons to 100,000 tons, greatly improving the wear resistance performance of the wear-resistant insert, extending its service life, and solving the problem of poor wear resistance of traditional horizontal looper pressure rollers.

[0011] As a further improvement of this utility model: the locking component is a round nut, which is threadedly connected to the top of the pressure roller base.

[0012] As a further improvement of this utility model, the pressure roller base is forged from 42CrMo alloy steel.

[0013] As a further improvement of this utility model: the height of the wear-resistant insert is 72mm, and the diameter of the inner ring is 126mm; the height of the second step is 72mm.

[0014] As a further improvement of this utility model: the outer contour shape of the wear-resistant insert includes a first curved surface segment, a straight line segment connected to the first curved surface segment, and a second curved surface segment connected to the straight line segment. The radius of the rounded chamfer R1 of the first curved surface segment is 25mm, and the radius of the rounded chamfer R2 of the second curved surface segment is 25mm. The maximum diameter of the outer contour of the wear-resistant insert is 190mm, and the minimum diameter of the outer contour of the wear-resistant insert is 180mm.

[0015] As a further improvement of this utility model, the tungsten carbide roller ring is processed from a waste precision rolling mill roller ring. By processing the tungsten carbide roller ring from a waste precision rolling mill roller ring, waste material is utilized without incurring additional procurement costs, thereby improving wear resistance and reducing production costs.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model features a detachable connection between the wear-resistant insert and the pressure roller base. Once the wear-resistant points are worn, the wear-resistant insert can be replaced separately without scrapping the entire pressure roller, thus solving the problem of resource waste in traditional pressure rollers.

[0018] 2. This utility model achieves mechanical installation of the wear-resistant insert and the pressure roller base by using an interference fit, enabling the individual replacement of the wear-resistant insert and reducing energy consumption.

[0019] 3. This utility model uses tungsten carbide roller rings in wear-resistant inserts. Tungsten carbide material has high hardness and wear resistance superior to traditional roller materials. The wear resistance cycle of the tungsten carbide roller ring has been increased from the original steel throughput of 20,000 tons to 100,000 tons.

[0032] The present invention will now be further described in conjunction with the accompanying drawings and embodiments:

[0033] Implementation Case 1:

[0034] Please see Figure 2-4 A high-wire horizontal loose-loop pressure roller device with inlaid tungsten carbide roller ring wear-resistant sleeve includes a pressure roller base 12 and a wear-resistant sleeve 11. The wear-resistant sleeve 11 is fitted onto the pressure roller base 12 and is detachably connected to the pressure roller base 12. A locking component is installed on the top of the pressure roller base 12.

[0035] During installation, the wear-resistant insert 11 is assembled with the pressure roller base 12 and then installed as a whole at the horizontal loop inlet. Because the wear-resistant insert 11 and the pressure roller base 12 are detachably connected, once the wear-resistant points wear out, the wear-resistant insert 11 can be replaced individually, eliminating the need to scrap the entire pressure roller and solving the resource waste problem of traditional pressure rollers.

[0036] Furthermore, the wear-resistant insert 11 and the pressure roller base 12 are interference fit.

[0037] By using an interference fit between the wear-resistant insert 11 and the pressure roller base 12, the mechanical installation of the wear-resistant insert 11 and the pressure roller base 12 is achieved, enabling the individual replacement of the wear-resistant insert 11 and reducing energy consumption.

[0038] Furthermore, the pressure roller base 12 includes a first step portion 121, a second step portion 122, and a third step portion 123. The outer diameter of the first step portion 121 is smaller than the outer diameter of the second step portion 122, and the outer diameter of the second step portion 122 is smaller than the outer diameter of the third step portion 123.

[0039] Furthermore, the inner diameter of the wear-resistant insert 11 is equal to the outer diameter of the second step portion 122, and the height of the wear-resistant insert 11 is equal to the height of the second step portion 122.

[0040] In addition, traditional pressure rollers have poor wear resistance and need to be replaced after passing only about 20,000 tons of steel. To improve local wear resistance, spot welding of wear-resistant materials is usually used. However, due to the influence of the welding process, the wear-resistant layer is easy to fall off, resulting in unstable service life.

[0041] Therefore, the wear-resistant insert 11 of this utility model adopts a tungsten carbide roller ring.

[0042] By using tungsten carbide roller rings in the wear-resistant insert 11, the wear resistance of which is superior to that of traditional roller materials due to the high hardness of tungsten carbide material (≥90 HRA). The wear resistance cycle of the tungsten carbide roller ring has been increased from the original steel throughput of 20,000 tons to 100,000 tons. The wear resistance of the wear-resistant insert 11 has been greatly improved, the service life has been extended, and the problem of poor wear resistance of traditional horizontal looper pressure rollers has been solved.

[0043] Furthermore, the locking component is a round nut, which is threaded to the top of the pressure roller base 12.

[0044] Implementation Case 2:

[0045] A wear-resistant sleeve-type horizontal looper pressure roller device with embedded tungsten carbide roller rings includes a pressure roller base 12 and a wear-resistant sleeve 11. The wear-resistant sleeve 11 is fitted onto the pressure roller base 12, and the wear-resistant sleeve 11 and the pressure roller base 12 are detachably connected. A locking component is installed on the top of the pressure roller base 12. During installation, the wear-resistant sleeve 11 and the pressure roller base 12 are assembled and then installed as a whole at the horizontal looper inlet. The detachable connection between the wear-resistant sleeve 11 and the pressure roller base 12 facilitates the individual replacement of the wear-resistant sleeve 11. The wear-resistant sleeve 11 and the pressure roller base 12 are interference-fitted. The interference fit between the wear-resistant sleeve 11 and the pressure roller base 12 enables mechanical installation of the wear-resistant sleeve 11 and allows for individual replacement of the wear-resistant sleeve 11, thus reducing wear.

[0046] The pressure roller base 12 includes a first stepped portion 121, a second stepped portion 122, and a third stepped portion 123. The outer diameter of the first stepped portion 121 is smaller than the outer diameter of the second stepped portion 122, and the outer diameter of the second stepped portion 122 is smaller than the outer diameter of the third stepped portion 123. The inner diameter of the wear-resistant insert 11 is equal to the outer diameter of the second stepped portion 122, and the height of the wear-resistant insert 11 is equal to the height of the second stepped portion 122.

[0047] The wear-resistant insert 11 has a height of 72 mm and an inner diameter of 126 mm. The second step portion 122 has a height of 72 mm. The outer contour of the wear-resistant insert 11 includes a first curved surface segment 111, a straight line segment 112 connected to the first curved surface segment 111, and a second curved surface segment 113 connected to the straight line segment 112. The radius of the chamfer R1 of the first curved surface segment 111 is 25 mm, and the radius of the chamfer R2 of the second curved surface segment 113 is 25 mm. The maximum diameter of the outer contour of the wear-resistant insert 11 is 190 mm, and the minimum diameter of the outer contour of the wear-resistant insert 11 is 180 mm.

[0048] The wear-resistant insert 11 is made of tungsten carbide roller ring. By using tungsten carbide roller rings in the wear-resistant insert 11, the high hardness (≥90 HRA) of tungsten carbide material results in superior wear resistance compared to traditional roller materials. The wear resistance cycle of the tungsten carbide roller ring is increased from the original 20,000 tons of steel throughput to 100,000 tons. This significantly improves the wear resistance of the wear-resistant insert 11, extends its service life, and solves the problem of poor wear resistance in traditional horizontal looper pressure rollers. The locking component is a round nut, which is threaded to the top of the pressure roller base 12.

[0049] The tungsten carbide roll ring is manufactured from scrap precision rolling roll rings. By manufacturing the tungsten carbide roll ring from scrap precision rolling roll rings, the use of scrap materials is achieved without incurring additional procurement costs, thereby improving wear resistance and reducing production costs.

[0050] The outer side of the first step portion 121 of the pressure roller base 12 is provided with an M120×4 thread structure, and the thread structure on the outside of the first step portion 121 is axially fixed by a high-strength round nut. The surface of the round nut is galvanized to enhance its rust resistance.

[0051] Implementation Case 3:

[0052] A wear-resistant sleeve-type horizontal looper pressure roller device with embedded tungsten carbide roller rings includes a pressure roller base 12 and a wear-resistant sleeve 11. The wear-resistant sleeve 11 is fitted onto the pressure roller base 12, and the wear-resistant sleeve 11 and the pressure roller base 12 are detachably connected. A locking component is installed on the top of the pressure roller base 12. During installation, the wear-resistant sleeve 11 and the pressure roller base 12 are assembled and then installed as a whole at the horizontal looper inlet. The detachable connection between the wear-resistant sleeve 11 and the pressure roller base 12 facilitates the individual replacement of the wear-resistant sleeve 11. The wear-resistant sleeve 11 and the pressure roller base 12 are interference-fitted. The interference fit between the wear-resistant sleeve 11 and the pressure roller base 12 enables mechanical installation of the wear-resistant sleeve 11 and allows for individual replacement of the wear-resistant sleeve 11, thus reducing wear. The pressure roller base 12 includes a first stepped portion 121, a second stepped portion 122, and a third stepped portion 123. The outer diameter of the first stepped portion 121 is smaller than the outer diameter of the second stepped portion 122, and the outer diameter of the second stepped portion 122 is smaller than the outer diameter of the third stepped portion 123. The inner diameter of the wear-resistant insert 11 is equal to the outer diameter of the second stepped portion 122, and the height of the wear-resistant insert 11 is equal to the height of the second stepped portion 122. The height of the wear-resistant insert 11 is 72mm, and the diameter of its inner ring is 126mm. The height of the second stepped portion 122 is 72mm. The outer contour shape of the wear-resistant insert 11 includes a first curved surface segment 111, a straight line segment 112 connected to the first curved surface segment 111, and a second curved surface segment 113 connected to the straight line segment 112. The radius of the chamfer R1 of the first curved surface segment 111 is 25mm, and the radius of the chamfer R2 of the second curved surface segment 113 is 25mm. The maximum outer diameter of the wear-resistant insert 11 is 190mm, and the minimum outer diameter is 180mm. The wear-resistant insert 11 is made of tungsten carbide roller rings. By using tungsten carbide roller rings in the wear-resistant insert 11, the high hardness (≥90 HRA) of the tungsten carbide material results in superior wear resistance compared to traditional roller materials. The wear cycle of the tungsten carbide roller ring is increased from the original 20,000 tons of steel throughput to 100,000 tons, significantly improving the wear resistance of the wear-resistant insert 11, extending its service life, and solving the problem of poor wear resistance in traditional horizontal looper pressure rollers. The locking component is a round nut, which is threaded to the top of the pressure roller base 12. The tungsten carbide roller ring is processed from scrap precision rolling roller rings. By processing the tungsten carbide roller ring from scrap precision rolling roller rings, waste material is utilized without incurring additional procurement costs, improving wear resistance while reducing production costs. The interference fit tolerance is H7 / s6.

[0053] During processing, the wear-resistant insert 11 is processed as follows: A scrap 8-inch precision-rolled tungsten carbide roller ring (initial outer diameter Φ228mm) is selected and ground into the outer diameter of a horizontal looper pressure roller using a grinding machine. The surface roughness is controlled to Ra≤0.8μm to ensure fitting accuracy. The inner ring of the ground wear-resistant insert 11 is Φ126mm and 72mm thick. The outer contour of the wear-resistant insert 11 includes a first curved surface segment 111, a straight line segment 112 connected to the first curved surface segment 111, and a second curved surface segment 113 connected to the straight line segment 112. The radius of the chamfer R1 of the first curved surface segment 111 is 25mm, and the radius of the chamfer R2 of the second curved surface segment 113 is 25mm. The maximum diameter of the outer contour of the wear-resistant insert 11 is 190mm, and the minimum diameter is 180mm.

[0054] The fabrication of the pressure roller base 12 includes: the pressure roller base 12 is forged from 42CrMo alloy steel and heat-treated to a hardness of HRC28-32; the outer diameter of the pressure roller base 12 is machined to Φ126.05-126.10mm, and a top thread (M120×4) is machined for locking with a round nut.

[0055] Assembly and installation: Heat the wear-resistant insert 11 to 200-250℃ to expand its inner ring and make it interference fit with the outer circle of the base; after cooling, tighten the round nut (torque ≥800N·m) to ensure that the wear-resistant insert 11 is axially fixed; install the assembled pressure roller device to the horizontal loop inlet.

[0056] When the rolled piece passes through the horizontal looper, the tungsten carbide roll ring bears the frictional load, and its high hardness and wear resistance greatly reduce wear. When the tungsten carbide roll ring is partially worn, only the round nut needs to be removed to replace the tungsten carbide roll ring, and the pressure roll base 12 can be reused.

[0057] By processing waste tungsten carbide roller rings into wear-resistant inserts 11 and using an interference fit and mechanical locking with the pressure roller base 12, the problems of poor wear resistance, resource waste, and high cost of traditional pressure rollers are solved. Its wear resistance is improved to a steel throughput of 100,000 tons, allowing for individual replacement of the wear-resistant inserts 11. The pressure roller base 12 can be 100% reused, while reducing production costs by more than 60%. This utility model is suitable for high-speed wire rod production lines and has significant economic benefits and promotional value.

[0058] The main functions of this utility model are:

[0059] This invention features a detachable connection between the wear-resistant insert and the pressure roller base. Once the wear points wear out, the wear-resistant insert can be replaced individually, eliminating the need to scrap the entire pressure roller and solving the resource waste problem of traditional pressure rollers. The interference fit between the wear-resistant insert and the pressure roller base enables mechanical installation of the insert and allows for individual replacement of the insert, reducing energy consumption. The wear-resistant insert uses a tungsten carbide roller ring, which has high hardness and superior wear resistance compared to traditional roller materials. The wear resistance cycle of the tungsten carbide roller ring has been increased from the original 20,000 tons of steel throughput to 100,000 tons, significantly improving the wear resistance of the insert, extending its service life, and solving the problem of poor wear resistance in traditional horizontal looper pressure rollers.
