Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel annealing furnaces, specifically to a tension adjustment mechanism for stainless steel annealing furnaces that prevents sticking and dead coiling. Background Technology

[0002] A stainless steel annealing furnace is a specialized piece of equipment used to eliminate internal stresses generated during the processing of stainless steel materials, improve their microstructure, and enhance their properties. It works by heating the material to a specific temperature, holding it at that temperature, and then controlling the cooling rate to adjust the metal's properties. When processing stainless steel coils, ensuring the proper transport of the coils requires the use of tensioning components to keep them taut. In the prior art, authorized publication number CN 211441784... U proposes a tension adjustment mechanism for an embossing device for stainless steel sheets, including a base. A roll unwinding frame is located on the left side of the base, and a roll unwinding shaft is rotatably connected to the roll unwinding frame above the base. A groove is formed at the top and center of the base, and a horizontal plate is connected within the groove. A roller support frame is fixedly connected to the top of the horizontal plate within the groove, and a roller shaft is fixedly connected within the roller support frame. A conveying roller is connected to the roller shaft. Push cylinders are fixedly connected to both sides at the bottom of the groove and the center of the horizontal plate. Although this mechanism can adjust the tension of the stainless steel coil, during the adjustment process, due to continuous operation of the adjustment components by personnel, over-adjustment may occur, leading to excessive tension in the stainless steel coil. This can cause the stainless steel coil to stick and become stuck during the operation of the stainless steel annealing furnace. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a tension adjustment mechanism for stainless steel annealing furnaces that prevents sticking and dead coils. This mechanism blocks the continuous increase of stainless steel coil tension, avoids excessive tension of stainless steel coils that leads to sticking and dead coils in the stainless steel annealing furnace, and ensures the production quality of stainless steel annealing furnaces. It can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a tension adjustment mechanism for a stainless steel annealing furnace that avoids sticking and dead coiling, comprising a support shell, wherein there are two support shells distributed front and back, and an adjusting slide is vertically slidably connected inside each support shell, a tension roller is rotatably connected between the two adjusting slides, and guide rollers are rotatably connected at both ends of the two support shells, and an adjustment component is also included.

[0005] Adjustment assembly: It includes an adjustment plate, sliding column, sleeve, spring 1, and limiting slide groove. The adjustment plate is vertically slidably connected to the inside of the support shell. Sliding columns are provided at both ends of the adjustment plate. The outer arc surface of the sliding column is vertically slidably connected to the sleeve with elastic limiting insertion. Limiting slide grooves are respectively set at the left and right ends of the adjustment slide. The lower limiting ring of the sleeve is vertically slidably connected to the inside of the limiting slide groove. Spring 1 is provided between the upper limiting ring of the sleeve and the upper surface of the adjustment slide. Spring 1 is movably sleeved on the outer arc surface of the sleeve. When the stainless steel coil tension reaches a certain value, it pushes the sliding column and the sleeve to slide relative to each other, preventing the stainless steel coil tension from continuously increasing. This prevents the operator from continuously turning the adjustment knob, which could lead to excessive tension. It also avoids the stainless steel coil from sticking and becoming stuck in the stainless steel annealing furnace due to excessive tension, thus ensuring the production quality of the stainless steel annealing furnace.

[0006] Furthermore, the adjustment assembly also includes a limiting cylinder and a connecting pin. The limiting cylinder is respectively disposed on the upper end of the outer arc surface of the sleeve. The inner side of the limiting cylinder is laterally slidably connected with an elastically limited connecting pin. The semi-circular end of the connecting pin passes through the clearance hole on the surface of the sleeve and is inserted into the insertion hole on the outer arc surface of the sliding pin, providing insertion limit between the sliding pin and the sleeve.

[0007] Furthermore, each of the connecting pins has a fixed ring on its outer arc surface and a movable ring that is laterally slidably connected to its outer arc surface. A second spring is provided between the movable ring and the fixed ring located on the same outer arc surface of the connecting pin. The second spring is movably sleeved on the outer arc surface of the connecting pin to provide elastic limiting for the connecting pin.

[0008] Furthermore, the adjustment assembly also includes a cover, which is threaded to the opening at the end of the limiting cylinder. The cover has a clearance hole in the middle that cooperates with the connecting post to seal the opening of the limiting cylinder, making it convenient to replace the second spring.

[0009] Furthermore, the adjustment assembly also includes adjustment screws, which are rotatably connected to the upper end of the support shell and threadedly connected to the screw holes in the middle of the adjustment plate, so as to facilitate the adjustment of the vertical position of the adjustment plate.

[0010] Furthermore, the upper surface of the adjusting slide is provided with a sealing shell, which is installed in conjunction with the clearance sliding hole on the surface of the support shell to prevent external dust from entering the interior of the support shell through the clearance sliding hole on the surface of the support shell.

[0011] Furthermore, the front surface of each adjusting slide is provided with a transparent scale plate, which is installed in conjunction with the observation window on the surface of the support shell to facilitate the determination of the extension and retraction range of the spring.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This tension adjustment mechanism for stainless steel annealing furnace that avoids sticking and dead coiling has the following advantages:

[0013] When the tension of the stainless steel coil reaches a certain value, it pushes the sliding column and the sleeve to slide relative to each other, preventing the tension of the stainless steel coil from increasing continuously. This prevents the operator from continuously turning the adjustment knob, which could lead to excessive tension. It also avoids the stainless steel coil from sticking and becoming stuck in the stainless steel annealing furnace due to excessive tension, thus ensuring the production quality of the stainless steel annealing furnace.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5This embodiment provides a technical solution: a tension adjustment mechanism for a stainless steel annealing furnace that avoids sticking and dead coils, including a support shell 1. There are two support shells 1 distributed front and back to provide space for the tension adjustment component. An adjustment slide 2 is vertically slidably connected inside each support shell 1. A tension roller 3 is rotatably connected between the two adjustment slides 2. The tension roller 3 is moved up and down by the adjustment slides 2 to adjust the tension of the stainless steel. Guide rollers 4 are rotatably connected at both ends of the two support shells 1. Both guide rollers 4 are in contact with the lower surface of the stainless steel coil. The two guide rollers 4 guide the conveying trajectory of the stainless steel coil. The embodiment also includes an adjustment component 5.

[0022] Adjustment component 5 includes an adjustment plate 51, sliding columns 52, sleeves 53, a spring 54, and a limiting groove 55. The adjustment plate 51 is vertically slidably connected to the inside of the support shell 1. Sliding columns 52 are provided at both ends of the adjustment plate 51. The outer arc surface of each sliding column 52 is vertically slidably connected to a sleeve 53 with elastic limiting insertion. The limiting grooves 55 are respectively located at the left and right ends of the adjustment slide block 2. The lower limiting rings of the sleeves 53 are vertically slidably connected to the inside of the limiting grooves 55. A spring 54 is provided between the upper limit ring of the sleeve 53 and the upper surface of the adjusting slide 2. The spring 54 is movably sleeved on the outer arc surface of the sleeve 53. During tension adjustment, the adjusting plate 51 drives the sliding column 52 to move downward. Due to the limiting insertion of the sliding column 52 and the sleeve 53, the sleeve 53 will move downward together. The lower limit ring of the sleeve 53 rotates in the limiting slide groove 55, pushing the spring 54 to contract and generate elastic force. Using the elastic force of the spring 54, the adjusting slide 2 is pushed. The tensioning roller 3 moves downward together with the tensioning roller 3, so that the tensioning roller 3 applies a downward force to the stainless steel coil, thus tensioning the stainless steel coil. By changing the contraction amplitude of the spring 54, the tension of the stainless steel coil can be adjusted. During the adjustment process, when the lower limit ring of the sleeve 53 contacts the bottom wall of the limit slide groove 55, the sleeve 53 and the adjusting slide 2 can no longer continue to slide relative to each other. As the adjusting plate 51 continues to move downward, under the action of the tension of the stainless steel coil, it will push the slide column 52 to slide relative to the sleeve 53. Continuous rotation of the adjusting screw 59 will not cause the tension of the stainless steel coil to exceed the safe range, avoiding the situation of sticking and dead coil in the stainless steel annealing furnace due to excessive tension of the stainless steel coil. The ends of the spring 54 are fixedly connected to the adjusting slide 2 and the sleeve 53 respectively by connecting bolts. The connecting bolts are rotated periodically to disassemble, replace and maintain the spring 54 to ensure the normal operation of the spring 54. The spring 54 can be made of nickel-based alloy material and can work in high-temperature environments.

[0023] The adjustment assembly 5 also includes a limiting cylinder 56 and a connecting pin 57. The limiting cylinder 56 is respectively disposed on the upper end of the outer arc surface of the sleeve 53. The inner side of each limiting cylinder 56 is laterally slidably connected with a connecting pin 57 that has elastic limiting. The semi-circular end of the connecting pin 57 passes through the clearance hole on the surface of the sleeve 53 and is inserted into the insertion hole on the outer arc surface of the sliding column 52. Through the elastic limiting of the connecting pin 57, the semi-circular end of the connecting pin 57 is inserted into the insertion hole of the column 52, thereby realizing the elastic insertion limiting between the sliding column 52 and the sleeve 53.

[0024] Each connecting pin 57 has a fixed ring 6 on its outer arc surface and a movable ring 7 that is laterally slidably connected to its outer arc surface. A second spring 8 is provided between the movable ring 7 and the fixed ring 6 located on the same outer arc surface of the connecting pin 57. The second spring 8 is movably sleeved on the outer arc surface of the connecting pin 57. With the cooperation of the fixed ring 6 and the cover 58, the movement range of the connecting pin 57 is limited. The elastic force of the second spring 8 provides elastic limit for the connecting pin 57. The second spring 8 can be made of nickel-based alloy and can work in high-temperature environments.

[0025] The adjusting assembly 5 also includes a cover 58, which is threaded to the opening at the end of the limiting cylinder 56. The cover 58 has a clearance hole in the middle for installation with the connecting pin 57, which blocks the opening of the limiting cylinder 56 and limits the movement range of the connecting pin 57. The cover 58 is rotated periodically to remove it, and the connecting pin 57 is pulled out from inside the limiting cylinder 56 to replace or maintain the second spring 8 and ensure its normal operation.

[0026] The adjustment assembly 5 also includes an adjustment screw 59, which is rotatably connected to the upper end of the support shell 1. The adjustment screw 59 is threadedly connected to the screw hole in the middle of the adjustment plate 51 to provide power for the up and down movement of the adjustment plate 51.

[0027] The upper surface of the adjusting slide 2 is provided with a sealing shell 9. The sealing shell 9 is installed in conjunction with the clearance sliding hole on the surface of the support shell 1. The front and rear sides of the sealing shell 9 are respectively attached to the front and rear inner walls of the support shell 1. During the vertical sliding and use of the adjusting slide 2, the sealing shell 9 is used to seal part of the clearance sliding hole on the upper part of the adjusting slide 2, preventing external dust from entering the interior of the support shell 1 through the clearance sliding hole on the surface of the support shell 1, and ensuring the normal operation of the transmission components inside the support shell 1.

[0028] The front surface of the adjusting slide 2 is provided with a transparent scale plate 10. The transparent scale plate 10 is installed in conjunction with the observation window on the surface of the support shell 1. During the up and down movement of the adjusting plate 51, the distance between the upper limit ring of the sleeve 53 and the upper surface of the adjusting slide 2 is determined by the scale on the surface of the transparent scale plate 10. This facilitates the determination of the extension and retraction range of the spring 54, ensuring that the extension and retraction ranges of the spring 54 on both the front and rear sides are the same, and ensuring that the vertical positions of the two adjusting slides 2 are the same. The observation window on the surface of the support shell 1 is provided with transparent glass. Both the transparent glass and the transparent scale plate 10 can be made of transparent quartz glass, which can work in high-temperature environments and prevent external dust from entering the interior of the support shell 1.

[0029] The working principle of the tension adjustment mechanism for a stainless steel annealing furnace that prevents the stainless steel coil from sticking is as follows: During the operation of the stainless steel annealing furnace, both guide rollers 4 are in contact with the lower surface of the stainless steel coil, guiding the conveying trajectory of the stainless steel coil. Rotating the adjusting screw 59, through the threaded connection between the adjusting screw 59 and the adjusting plate 51, causes the adjusting plate 51 to move the sliding column 52 downwards. Due to the insertion of the connecting pin 57 into the insertion hole of the sliding column 52, the sleeve 53 is moved downwards along with it. The lower limit ring of the sleeve 53 rotates within the limit groove 55, pushing the spring 54 to contract and generate elastic force. Using the elastic force of the spring 54, the adjusting slide block 2 and the tension roller 3 are moved downwards together, causing the tension roller 3... A downward force is applied to the stainless steel coil to tension it. The tension of the stainless steel coil can be adjusted by changing the contraction amplitude of spring 54. During the adjustment process, when the lower limit ring of sleeve 53 contacts the bottom wall of the limit slide groove 55, sleeve 53 and adjusting slide 2 can no longer continue to slide relative to each other. As the adjusting screw 59 continues to rotate, under the action of the tension of the stainless steel coil, it will overcome the elastic force of spring 8 and push the semi-circular end of connecting pin 57 away from the insertion hole of slide pin 52. Sleeve 53 and slide pin 52 slide relative to each other. Continuous rotation of adjusting screw 59 will not cause the tension of the stainless steel coil to exceed the safe range, thus avoiding the situation where the stainless steel coil sticks and becomes stuck in the stainless steel annealing furnace due to excessive tension.

[0030] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
