Abstract
Description
Technical Field
[0001] This application relates to the field of auxiliary equipment for material processing, and in particular to a tooling for preventing adhesion during annealing of multi-layer composite rolls. Background Technology
[0002] Annealing is a crucial process in coil processing. Coil annealing involves heating the coil to a specific temperature, holding it for a period, and then cooling it at a suitable rate. This process aims to soften the metal material, eliminate internal stress, and improve processing performance and surface quality. Due to increasingly stringent quality requirements for coils, preventing adhesion during annealing has become a critical issue. If adhesion occurs, the interlayer bonding force during unwinding or slitting can forcibly tear the metal surface, creating visible tears. Furthermore, the adhered areas may experience overheating or underheating due to impaired localized heat dissipation during annealing, resulting in inconsistent strength across different locations within the same coil.
[0003] Currently, there are various solutions in the industry to prevent the adhesion of coil materials during annealing. One common anti-adhesion measure is to apply an anti-adhesion agent to the coil material before annealing. This method has a significant anti-adhesion effect and is applicable to a variety of coil materials, which can meet diverse production needs to a certain extent. Another method is to prevent adhesion by controlling the annealing temperature and time. This method does not require additional materials, reducing costs, and does not introduce foreign substances, making it suitable for products with high requirements for surface purity.
[0004] However, existing anti-sticking measures all have significant drawbacks. While applying anti-stick agents is effective, residues often remain after annealing, requiring an additional cleaning process. This not only increases processing costs but also significantly reduces processing efficiency. Controlling annealing temperature and time is heavily limited by material properties; some materials must be annealed within specific temperature ranges, leaving very little room for adjustment. Furthermore, improper adjustments can severely impact annealing quality. In conclusion, existing anti-sticking measures for roll-to-roll annealing are cumbersome, resulting in low processing efficiency and warranting improvement. Utility Model Content
[0005] To address the problem of low processing efficiency caused by the cumbersome anti-sticking measures for roll annealing, this application provides a multi-layer composite roll annealing anti-sticking fixture.
[0006] This application provides a multi-layer composite roll annealing anti-adhesion fixture, which adopts the following technical solution:
[0007] A multi-layer composite roll annealing anti-adhesion fixture includes a receiving frame and anti-adhesion sheets. The receiving frame forms an abutment fit with one side of the roll along its axial direction. Abutment posts are arranged in an array along the circumference of the roll on the receiving frame, and any one of the abutment posts forms an abutment fit with the outermost radial side of the roll. Multiple anti-adhesion sheets are provided, and each anti-adhesion sheet includes a handle and an insertion part. Limiting grooves and anti-adhesion teeth located on both sides of the limiting grooves are linearly arranged on the insertion part. Any one of the anti-adhesion teeth is inserted from the side of the roll away from the receiving frame between any two adjacent layers of roll, and any one of the limiting grooves forms an embedded fit with any layer of roll.
[0008] By adopting the above technical solution, the receiving frame and the abutting column form an abutting fit with the roll material in the axial and radial directions, respectively, which can prevent the roll material from shifting during annealing, thereby avoiding adhesion caused by the movement of the roll material. The anti-adhesion plate consists of a handle and an insertion part. The handle is convenient for workers to operate, and the anti-adhesion teeth on the insertion part can be accurately inserted between two adjacent layers of roll material to play a physical isolation role. The limiting groove can ensure that the anti-adhesion plate and the roll material are fixed in position, thereby enhancing the anti-adhesion effect.
[0009] Preferably, the receiving frame is provided with support legs and heat dissipation gaps, and multiple support legs and heat dissipation gaps are provided.
[0010] By adopting the above technical solution, the support leg can keep the receiving frame at a certain distance from the bottom surface of the annealing equipment, avoid direct contact between the roll material and the high-temperature bottom surface, reduce the risk of adhesion caused by local overheating, and the heat dissipation gap can promote the flow of air around the roll material, accelerate heat dissipation, make the temperature distribution of the roll material more uniform during annealing, and effectively prevent local overheating from causing adhesion or causing different strengths in different parts of the same roll material.
[0011] Preferably, the length of the anti-sticking teeth decreases sequentially along their array direction.
[0012] By adopting the above technical solution, the length of the anti-sticking teeth is set to decrease sequentially along its array direction, so that the anti-sticking teeth on the insertion part are obliquely cut as a whole, which can better adapt to the structural characteristics and gap size of different positions of the roll material, thereby allowing the anti-sticking teeth to be inserted more smoothly between any two adjacent layers of roll material.
[0013] Preferably, the end of the anti-sticking tooth is provided with an unwinding tip.
[0014] By adopting the above technical solution, the unwinding tip can be easily inserted between tightly fitted layers of the roll material, reducing the difficulty of inserting the anti-sticking teeth, improving the ease of use of the tooling, and at the same time preventing the anti-sticking teeth from bending or deforming during the insertion process, thus extending the service life of the anti-sticking sheet.
[0015] Preferably, the receiving frame is provided with a circumferential array of plug-in posts, each of the plug-in posts having a plug-in groove along its axial direction, and each of the plug-in posts forming a plug-in fixed engagement with the support leg on the adjacent receiving frame through the plug-in groove.
[0016] By adopting the above technical solution, multiple receiving frames are stably stacked through the insertion and fixing of the plug-in columns and support legs. This facilitates batch processing of roll materials, makes full use of the space inside the annealing equipment, improves equipment efficiency, and the detachable connection method makes tooling assembly and disassembly simple, facilitates transportation and storage, and reduces operating costs.
[0017] Preferably, the abutment post is adjustable along the radial direction of the roll material on the receiving frame.
[0018] By adopting the above technical solution, the abutment post can be flexibly adjusted according to the outer diameter of the roll material, so that the tooling can firmly fix roll materials of different sizes, expanding the application range of the tooling. For roll materials of different thicknesses or diameters, the abutment post can be adjusted to achieve the best fixing effect and ensure stable anti-sticking effect.
[0019] Preferably, the handheld part is provided with a connecting hole, and a connecting pin is provided on the connecting hole. The connecting pin passes through any two connecting holes and is threadedly connected to a fixing nut.
[0020] By adopting the above technical solution, the hand-held part is provided with connecting holes, connecting pins and fixing nuts. When in use, the connecting pins pass through the connecting holes of different anti-sticking sheets and are fixed with fixing nuts, so that multiple anti-sticking sheets can be connected into a whole. This combination method can be flexibly adjusted according to the width and length of the roll material, which enhances the adaptability of the tooling. Moreover, the connected anti-sticking sheets are more stable during annealing, avoiding the shaking or displacement of individual anti-sticking sheets.
[0021] Preferably, the handgrip is provided with anti-slip protrusions, and multiple anti-slip protrusions are provided.
[0022] By adopting the above technical solution, setting multiple anti-slip protrusions on the handgrip can increase the friction between the operator's hand and the handgrip, which can effectively prevent slippage during operation, improve operational safety, and at the same time allow the operator to better control the insertion force and direction of the anti-sticking sheet, so that the anti-sticking sheet can be inserted more accurately between the layers of the roll material, thereby improving the tooling performance.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. The anti-sticking teeth of the anti-sticking sheet are inserted between any two adjacent layers of roll material, and the limiting groove forms an embedded fit with the roll material. This can effectively prevent the roll material from sticking together during the annealing process, thereby avoiding tearing of the metal surface during unwinding or slitting due to sticking, as well as the problem of inconsistent strength at different positions of the same roll material due to local heat dissipation obstruction. At the same time, the receiving frame is equipped with multiple support legs and heat dissipation gaps, which can significantly improve heat dissipation efficiency and ensure annealing quality during the annealing process.
[0025] 2. The length of the anti-sticking teeth decreases sequentially along their array direction, and an unwinding tip is provided at each end to facilitate the insertion of the anti-sticking sheet between the layers of the roll material, thereby improving the ease of use of the tooling. The insertion post on the receiving frame and the support leg of the adjacent receiving frame form an insertion and fixing fit through the insertion slot, which facilitates the assembly and construction of the tooling. It can make full use of the space inside the annealing equipment, making it suitable for batch use, and is also convenient for transportation and storage, reducing the cost of use.
[0026] 3. The abutment post is adjustable along the radial direction of the roll material on the receiving frame, which can adapt to roll materials of different sizes and improve the versatility of the tooling. The anti-sticking plate can be fixedly connected together by the cooperation of the connecting hole, connecting pin and fixing nut, so that the anti-sticking plate can be flexibly adjusted according to the width and length of the roll material, which enhances the adaptability of the tooling, and the connected anti-sticking plate is more stable during operation.

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail.
[0031] This application discloses a multi-layer composite roll annealing anti-adhesion tooling.
[0032] Reference Figure 1 and Figure 2 A multi-layer composite roll annealing anti-adhesion fixture includes a receiving frame 1 and anti-adhesion sheets 2. The receiving frame 1 forms an abutment fit with one side of the roll axially. Abutment posts 3 are arranged in a circumferential array on the receiving frame 1 along the roll, and any one of the abutment posts 3 forms an abutment fit with the outermost radial side of the roll. Multiple anti-adhesion sheets 2 are provided, and the melting point of each anti-adhesion sheet 2 is higher than that of the roll. Each anti-adhesion sheet 2 includes a handle portion 21 and an insertion portion 22. The handle portion 21 is provided with anti-slip protrusions 211, and multiple anti-slip protrusions 211 are provided. The insertion portion 22 is... The array has a limiting groove 221 and anti-sticking teeth 222 located on both sides of the limiting groove 221. Each anti-sticking tooth 222 is inserted between any two adjacent layers of the roll material from the side away from the receiving frame 1. Each limiting groove 221 is embedded with any layer of the roll material. The length of the anti-sticking tooth 222 decreases sequentially along its array direction. Each anti-sticking tooth 222 has an unwinding tip 2221 at its end through turning. In this embodiment, four anti-sticking sheets 2 are arranged in an array along the circumference of the roll material, and the four anti-sticking sheets 2 completely separate the layers of the roll material.
[0033] In practical use, the receiving frame 1 and the abutting post 3 form an abutting fit with the roll material in the axial and radial directions, respectively, which can prevent the roll material from shifting during annealing. The number of anti-sticking plates 2 can be selected according to the actual situation. They are inserted sequentially until each layer of the roll material is completely separated. The multiple anti-slip protrusions 211 on the handle 21 can increase the friction between the operator's hand and the handle 21, which can effectively prevent slipping during operation. The anti-sticking teeth 222 on the insertion part 22 can be accurately inserted between two adjacent layers of roll material, and the limiting groove 221 can ensure that the anti-sticking plate 2 and the roll material are fixed in position, thereby achieving a stable anti-sticking effect. The length of the anti-sticking teeth 222 is set to decrease sequentially so that the anti-sticking teeth 222 on the insertion part 22 are obliquely cut, which can be inserted more smoothly between any two adjacent layers of roll material. The unwinding tip 2221 can be easily inserted between tightly fitted roll material layers, reducing the difficulty of inserting the anti-sticking teeth 222.
[0034] Reference Figure 1 and Figure 2The receiving frame 1 includes a circular ring frame 11 and receiving rods 12 disposed on the ring frame 11. In this embodiment, eight receiving rods 12 are arranged in a circumferential array along the ring frame 11. One end of any receiving rod 12 is fixedly connected to the ring frame 11 by welding, and the other end is located at the center of the ring frame 11 and is fixedly connected to the ends of other receiving rods 12 by welding. A heat dissipation gap 121 is formed between any two adjacent receiving rods 12. A support leg 4 is arranged vertically on the side of the receiving frame 1 away from the roll material. In this embodiment, five support legs 4 are provided. One support leg 4 is fixedly connected to the end of the receiving rod 12 located at the center of the ring frame 11 by welding, and the other four support legs 4 are distributed in a circumferential array along the ring frame 11 and are fixedly connected to the ring frame 11 by welding.
[0035] In practical use, the receiving frame 1 is welded from the ring frame 11 and eight receiving rods 12, which can support the coil along its axial direction. A heat dissipation gap 121 is formed between any two adjacent receiving rods 12, making the temperature distribution more uniform during the annealing of the coil. The support legs 4 are all located on the side of the ring frame 11 away from the coil, so that the receiving frame 1 is kept at a certain distance from the bottom surface of the annealing equipment, reducing the risk of adhesion caused by local overheating.
[0036] Reference Figure 1 and Figure 2 The abutment post 3 is adjustable along the radial direction of the roll material on the support rod 12. In this embodiment, four abutment posts 3 are provided, and one end of any abutment post 3 is fixedly connected to an adjusting ring 31 by welding. The adjusting ring 31 is slidably disposed on any support rod 12, and a fixing bolt 32 that forms an abutment fit with the support rod 12 is threadedly connected to the adjusting ring 31. In actual use, a certain space is reserved before the roll material is separated, and then multiple anti-sticking sheets 2 are inserted until the layers of the roll material are completely separated. At this time, the abutment position of the abutment post 3 can be adjusted along its radial direction according to the actual size of the roll material. When the adjusting ring 31 slides to a suitable position on the support rod 12, the fixing bolt 32 can be screwed to tighten the support rod 12 for fixation.
[0037] Reference Figure 1 and Figure 2 The receiving frame 1 is provided with a circular array of insertion posts 5, and each insertion post 5 has an insertion groove 51 along its axial direction. In this embodiment, four insertion posts 5 are provided. Any one of the insertion posts 5 is fixedly connected to the receiving rod 12 by welding in the vertical direction, and any one of the insertion posts 5 forms an insertion fixed fit with the support leg 4 on the adjacent receiving frame 1 through the insertion groove 51. In actual use, the insertion post 5 and the support leg 4 on the adjacent receiving frame 1 are fixed by insertion through the insertion groove 51, which can make full use of the space inside the annealing equipment. Moreover, the detachable connection method makes the tooling assembly and disassembly simple, and facilitates transportation and storage.
[0038] Reference Figure 1 and Figure 2 The handle 21 is provided with a connecting hole 212, and a connecting pin 213 is provided on the connecting hole 212. The connecting pin 213 passes through any two connecting holes 212 and is threadedly connected to a fixing nut 214. In this embodiment, the anti-stick sheet 2 is rectangular, and there are two connecting holes 212 along the width direction of the anti-stick sheet 2. In actual use, the connecting pin 213 passes through the connecting holes 212 of different anti-stick sheets 2 and is fixed by the fixing nut 214. Multiple anti-stick sheets 2 can be connected into a whole, so as to flexibly adjust according to the width and length of the roll material and avoid the shaking or displacement of a single anti-stick sheet 2.
[0039] The implementation principle of this application embodiment is as follows: During the annealing process of the roll material, the receiving frame 1 abuts against one side of its axial direction, and multiple adjustable abutment columns 3 abut against its outermost radial direction, thereby preventing the roll material from shifting and adapting to roll materials of different sizes. The receiving frame 1 is welded from the ring frame 11 and the receiving rod 12. The heat dissipation gap 121 formed by it can make the annealing temperature distribution of the roll material more uniform, which can effectively prevent local high temperature from causing adhesion or causing different strengths at different positions of the same roll material. The support leg 4 keeps the receiving frame 1 at a distance from the bottom surface of the annealing equipment, avoiding direct contact between the roll material and the high temperature bottom surface, reducing the risk of adhesion. The handle 21 of the anti-stick sheet 2 is provided with anti-slip protrusions 211, which can increase the friction between the operator's hand and the handle 21, and can effectively prevent slipping during operation.
[0040] The anti-sticking teeth 222 of the plug-in part 22 can be inserted between two adjacent layers of roll material to play a physical isolation role. At the same time, the limiting groove 221 ensures that its position is fixed, thereby enhancing the anti-sticking effect. The design of the decreasing length of the anti-sticking teeth 222 and the unwinding tip 2221 reduces the difficulty of inserting the anti-sticking sheet 2 and achieves a stable anti-sticking effect. The plug-in post 5 and the support leg 4 make full use of space and facilitate the assembly and disassembly of the tooling. The anti-sticking sheet 2 can be connected into a whole by the connecting pin 213 and the fixing nut 214, which can be flexibly adjusted according to the roll material specifications to ensure the stability and flexibility of the tooling.
[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
