Description

Technical Field

[0001] This utility model relates to the field of roller technology, and in particular to a highly reliable fiber roller. Background Technology

[0002] Bright annealing furnaces are used to heat-treat stainless steel products under a protective gas atmosphere and can be used for strip steel. The stability of the strip steel during its operation within the furnace is crucial, and the internal equipment of the furnace is key to the production of bright strip steel. Because the fiber rollers in the bright annealing furnace are constantly exposed to high-temperature hydrogen gas at around 400°C, extremely high requirements are placed on the structure and material of the fiber rollers during the production process to ensure their performance. Currently, the existing fiber roller technology, as shown in Chinese Utility Model Patent Application No. CN202222465849.9 (Authorization Announcement No. CN218227330U), includes a rotating shaft, an inner roller, several connecting components, an outer roller ring, and a carbon fiber sleeve. The rotating shaft passes through the inner roller and is fixedly connected to it. Several connecting components are installed on the outside of the inner roller and are evenly distributed around it. The ends of the connecting components furthest from the inner roller are fixedly connected to the outer roller ring. The carbon fiber sleeve is fixedly installed on the outside of the outer roller ring, thus forming the fiber roller.

[0003] Existing fiber rollers typically consist of a roller core and multiple fiber roller sleeves. These sleeves are fitted over the roller core. To ensure stable mounting, adjacent sleeves are connected by gaskets; the two ends of the gaskets press against the adjacent sleeves. However, in actual use, the strip moves across the roller surface, and the roller rotates due to the drive mechanism, generating axial and radial forces. These forces cause slight reciprocating slippage of the sleeves, squeezing the gaskets between adjacent sleeves. This causes the gaskets to protrude above the roller surface, resulting in indentations on the strip surface and affecting production quality. Therefore, further improvements to the fiber roller are necessary. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a fiber roller with a simple structure that can ensure the stability of the roller sleeve, thereby making the fiber roller highly reliable, in light of the above-mentioned existing technology.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: The high-reliability fiber roller includes a roller core and multiple roller sleeves, characterized in that: multiple grooves are provided on the outer peripheral wall of the roller, the grooves are straight grooves extending along the axial direction of the roller core or spiral grooves extending along the circumferential direction of the roller core, the two ends of the grooves are connected to the outside, a metal wire is fixed in the groove, the outer end of the metal wire protrudes from the outer peripheral surface of the roller core, and the roller sleeve is fitted on the roller core, the metal wire and the inner peripheral wall of the roller sleeve form an interference fit to abut against the roller sleeve.

[0006] Furthermore, the outer peripheral wall of the roller core is provided with eight grooves, which are evenly distributed on the outer peripheral wall of the roller core. That is, the eight grooves form an eight-eight-part structure on the outer peripheral surface of the roller core. The eight grooves arranged in this way can make the force of the metal wire acting on the roller sleeve more even, so that the roller sleeve is more stably fixed on the roller core.

[0007] Furthermore, the cross-section of the metal wire is circular, and the metal wire is tin bronze wire. The alloy structure of tin bronze wire makes the wire harder and more corrosion resistant, making it suitable for use between the roller core and the roller sleeve, thus improving the stability of the roller sleeve fixed to the outer periphery of the roller core.

[0008] Furthermore, the groove has a depth of 0.7–0.8 mm, a width of 2.4–2.6 mm, a diameter of 2.45–2.55 mm, and the outer end of the metal wire protruding from the outer circumference of the roller core has a height of 1.65–1.85 mm. This arrangement of the groove and metal wire allows the roller sleeve to be fitted into the roller core using a hydraulic press, while also ensuring that the metal wire protruding from the outer circumference of the roller core abuts against the inner circumferential wall of the roller sleeve, guaranteeing effective contact.

[0009] Furthermore, the metal wire is fixedly connected to the groove by welding. The welding can be done by intermittent spot welding, with a weld spacing of 15-20mm, a weld depth of 0.3-0.5mm, and a weld width of ≤1.2mm. The welds are welded using pulsed laser welding. This spot welding method can improve the installation efficiency of fixing the metal wire in the groove and ensure the stability of the metal wire fixed in the groove.

[0010] Furthermore, it also includes two pressure blocks, which are respectively pressed onto both ends of the roller core, and the pressure blocks can abut against adjacent roller sleeves. The pressure blocks arranged in this way can further restrict the roller sleeves, thereby preventing the roller sleeves from coming off the roller core.

[0011] Compared with the prior art, the advantages of this utility model are as follows: The fiber roller of this application utilizes metal wires protruding from the outer circumferential surface of the roller core to abut against the inner circumferential wall of the roller sleeve, so that the metal wires abut against the roller sleeve, thereby stably fitting the roller sleeve onto the roller core. The roller sleeve will not rotate relative to the roller core, improving the stability of the roller sleeve in the fiber roller. Furthermore, during actual operation, even if the fiber roller is subjected to external forces, the metal wires used to fix the roller sleeve will not affect the surface quality of the product, i.e., no foreign objects protrude from the outer circumferential surface of the roller sleeve, thus ensuring the production quality of the product and providing technical support for manufacturing in the metallurgical industry. Therefore, the fiber roller of this application has a simple structure, high reliability, and can guarantee the production quality of the product. In addition, the spiral groove can increase the contact area between the metal wires and the inner circumferential wall of the roller sleeve, making the roller sleeve more stably fitted onto the roller core, and further enhancing the reliability of the fiber roller.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1 and Figure 2 The image shown is the preferred embodiment of this utility model.

[0016] The fiber roller of this embodiment includes a roller core 1 and six roller sleeves 2. The outer peripheral wall of the roller core 1 is provided with eight spaced grooves 11. The eight grooves 11 are evenly distributed on the outer peripheral wall of the roller core 1. The grooves 11 are straight grooves extending along the axial direction of the roller core 1. The two ends of the grooves 11 are connected to the outside. A metal wire 3 is fixed to the groove 11. The cross-section of the metal wire 3 is circular. The metal wire 3 is a tin bronze wire. The outer end of the metal wire 3 protrudes from the outer peripheral surface of the roller core 1. Specifically, the depth of the groove 11 is 0.75 mm, the width of the groove 11 is 2.5 mm, the diameter of the metal wire 3 is 2.5 mm, and the height of the outer end of the metal wire 3 protruding from the outer peripheral surface of the roller core 1 is 1.75 mm. The metal wire 3 and the groove 11 are fixedly connected by welding. The welding adopts the method of intermittent spot welding to fix the metal wire 3 and the groove 11.

[0017] In this embodiment, with the roller sleeve 2 fitted onto the roller core 1, the metal wire 3 forms an interference fit with the inner circumferential wall of the roller sleeve 2 to hold it in place. This ensures that the roller sleeve 2 is stably fitted onto the new roller core 1, preventing it from rotating relative to the roller core 1 and improving the stability of the roller sleeve 2 in the fiber roller. Furthermore, this embodiment of the fiber roller also includes two pressure blocks 4, which are respectively pressed onto both ends of the roller core 1. The pressure blocks 4 can hold adjacent roller sleeves 2 in place, thereby preventing the roller sleeve 2 from detaching from the roller core 1.

[0018] The installation process in this embodiment is as follows: First, eight grooves 11 are formed on the outer peripheral wall of the roller core 1. Then, metal wires 3 are installed in each groove 11 and fixed in the grooves 11 by spot welding. Then, six roller sleeves 2 are fitted onto the roller core 1 using a hydraulic press, so that the metal wires 3 protruding from the outer peripheral wall of the roller core 1 can abut against the inner peripheral wall of each roller sleeve 2. Then, pressure blocks 4 are installed at both ends of the roller core 1, so that the six roller sleeves 2 are fixed on the roller core 1. Finally, the roller surface of the installed fiber roller is ground and polished to ensure that the fiber roller reaches the set roughness and the roller surface of the fiber roller is free of defects.

[0019] Alternatively, the groove 11 in this embodiment can also be a spiral groove extending circumferentially along the roller core 1. The groove 11 provided in this way can increase the contact area between the metal wire 3 and the inner circumferential wall of the roller sleeve 2, so that the roller sleeve 2 can be more stably fitted onto the roller core 1.
