Description

Technical Field

[0001] The present application relates to the field of metal processing technology, and in particular to a stainless steel strip rewinding machine and a production method. Background Art

[0002] Rewinder is a very important equipment, which is widely used in paper, steel, plastic and other industries. Rewinder can rewind the processed steel strip, making the coil surface flat after winding. When used in other processing structures, the unwinding position is stable and the deviation is reduced.

[0003] When some rewinders are rewinding steel strips, the strips become loose due to insufficient tension, and are prone to deviation during the rewinding process, resulting in the rewinding surface being skewed after the entire rewinding, affecting subsequent use. Summary of the Invention

[0004] In order to improve the above problems, the present application provides a stainless steel strip rewinding machine and a production method.

[0005] The present application provides a stainless steel strip rewinding machine and production method using the following technical solutions: A stainless steel strip rewinder comprises a driving body, a mobile body, a receiving base and a pressing mechanism; the driving body is provided with a driving mechanism providing a winding drive; the mobile body is provided with a winding roller for winding the steel strip, the winding roller is detachably connected to the driving mechanism, and the mobile body provides lifting and movement of the wound steel strip; the pressing mechanism is installed on the driving body and contacts with the wound steel strip to provide pressing; the receiving base is arranged below the mobile body, and the mobile body drives the steel strip coil to move to the receiving base, so that the receiving base receives the steel strip coil.

[0006] By adopting the above technical solution, after the steel strip is wound on the winding roller, the driving mechanism drives the winding roller to rotate, thereby driving the steel strip to be wound and gradually forming a steel strip coil. During the winding process, the pressing mechanism contacts the steel strip and applies pressure to the steel strip to lower the winding roller, so that the steel strip is compacted and the steel strip is rewound tightly during winding. After winding, the mobile body drives the winding roller to separate from the driving mechanism and moves to the receiving base at the same time. The lifting action of the mobile mechanism is used to lower the steel strip coil and place it on the receiving base, so as to achieve a stable and tight rewound steel strip coil and facilitate the recovery of the rewound steel strip coil.

[0008] By adopting the above technical solution, after the locking structure is plugged into the winding roller, the locking structure is used to fix the plugging position of the winding roller, so that when the drive motor drives the drive shaft to rotate, the winding roller can be driven to rotate synchronously through the locking structure.

[0009] Optionally, the locking structure includes a locking cylinder, which is connected to the drive shaft; a plurality of locking grooves are provided on the inner wall of the locking cylinder, and a locking hole is provided at the end of the locking groove; an ejection hole matching the locking hole is provided on the outer wall of the winding roller, and a connecting plug is provided inside the winding roller, a telescopic groove is provided in the connecting plug, and an ejection spring is provided in the telescopic groove; a locking protrusion is slidably connected in the ejection hole, and the locking protrusion is connected to the ejection spring, and the ejection spring provides the elastic force for the locking protrusion to eject the ejection hole and the locking hole.

[0010] By adopting the above technical solution, when the winding roller is plugged into the locking cylinder, the locking protrusion passes through the ejection hole and moves along the locking groove until it moves to the locking hole. The locking protrusion is acted upon by the elastic force of the ejection spring and is clamped into the locking hole from the locking groove, thereby achieving the locking effect.

[0011] Optionally, the rolling mechanism includes a rolling roller, a rolling frame, a rolling shaft, a receiving frame and a rolling drive unit; the rolling drive unit is installed on the driving body; the receiving frame is installed on the driving body and is provided with a pivot hole; the rolling shaft is pivotally connected to the receiving frame through the pivot hole and is connected to the driving end of the rolling drive unit; the rolling frame is installed on the rolling shaft, the rolling roller is pivotally connected to the rolling frame, and the rolling roller contacts the steel strip roll and rotates accordingly.

[0012] By adopting the above technical solution, the pressure coil driving unit drives the pressure coil shaft to rotate along the receiving frame through the pivot hole, and drives the pressure coil frame to rotate during the rotation process. The pressure coil roller is located on the pressure coil frame, so it contacts the steel strip roll during the movement of the pressure coil frame, so that the pressure coil roller can apply pressure to the steel strip roll, thereby providing a stable pressing effect on the steel strip roll when rewinding, so as to ensure the accurate and stable position of the steel strip roll after rewinding.

[0013] Optionally, the driving body is further provided with a boosting mechanism, and the boosting mechanism is connected to the rolling mechanism.

[0014] By adopting the above technical solution, the diameter of the steel strip coil will continue to increase as it is continuously rewound, and the pressure of the coil pressing mechanism on the continuously increasing steel strip coil will continue to change. Therefore, a boosting mechanism is set up to balance the pressure on the steel strip coil.

[0015] Optionally, the pressurizing mechanism comprises a fixed part, a telescopic cylinder, an elastic part and a sensing part; the fixed part is connected with the driving body; the telescopic cylinder is connected with the fixed part; the sensing part is installed on the pressing frame; one end of the elastic part is hinged with the telescopic cylinder, and the other end is hinged with the sensing part.

[0016] By adopting the above technical scheme, when the pressing mechanism needs to provide stable pressure to the steel strip coil as the steel strip coil is continuously wound, the elastic part generates tension through the sensing part to pull the pressing frame, so that the pressing frame and the pressing roller increase the pressure on the steel strip coil, and then when the steel strip coil continuously increases, the pressing frame and the pressing roller move synchronously, so that the elastic part is elongated to generate greater tension, so that the sensing part senses that the tension is greater than a preset value, so that the telescopic cylinder is elongated, so that the tension of the elastic part is reduced to the preset value, and the above process is repeated to achieve the pressurizing effect of providing a stable pressure value to the pressing mechanism.

[0017] Optionally, the moving body comprises a first moving seat, a second moving seat, a lifting cylinder, a pivoting table, a disengaging cylinder and a moving rail; the moving rail is connected with the driving body; the first moving seat and the second moving seat are both provided with rolling parts at the bottom and are slidably connected with the moving rail through the rolling parts; the first moving seat and the second moving seat are both provided with lifting cylinders, and the top of the lifting cylinder is provided with a pivoting table; the winding roller is pivotally connected with the pivoting table; the disengaging cylinder is connected with the second moving seat, and the driving end is connected with the driving body.

[0018] By adopting the above technical scheme, the first moving seat and the second moving seat provide support to the winding roller through the pivoting table respectively, and the moving path of the first moving seat and the second moving seat is limited by the moving rail; the driving body is pushed by the disengaging cylinder, so that the second moving seat drives the winding roller to move away from the driving body until it is located above the receiving base; the steel strip coil is abutted with the receiving base by the lifting cylinder, so as to facilitate the recycling of the steel strip coil.

[0019] Optionally, the outer wall of the driving body is further provided with a limiting cylinder, the telescopic end of the disengaging cylinder is further provided with a linkage rod, and the telescopic end is inserted into the limiting cylinder and slides along the limiting cylinder; a limiting groove is formed in the inner wall of the fixed part, and a sliding opening is formed in the outer wall of the fixed part; an unlocking ring is further arranged in the fixed part and slidably connected with the limiting groove and the sliding opening; the linkage rod penetrates through the sliding opening and is connected with the unlocking ring; the disengaging cylinder drives the linkage rod to move, so that the unlocking ring is in contact with the locking protrusion to release the locking state.

[0020] By adopting the above technical solution, when the steel strip coil is rewound, the locking effect needs to be unlocked, and the telescopic end of the cylinder is separated and moves toward the driving body along the limit cylinder. During the movement, it drives the linkage rod to move, and the linkage rod drives the unlocking ring to move along the sliding mouth. The unlocking ring presses down the locking protrusion, so that the locking protrusion returns to the locking hole and the locking groove. Then the telescopic end of the cylinder is separated and contacts the driving body and pushes the driving body. The reaction force moves the second moving seat away from the driving body, and simultaneously separates the winding roller that has lost the locking effect of the locking protrusion from the locking cylinder to achieve the effect of integrated unlocking.

[0021] Optionally, the pivot platform includes a load-bearing bearing, a pivot shaft and a conical wheel; the load-bearing bearing is provided in two groups, respectively located on both sides of the driving end of the lifting cylinder; the pivot shaft is pivotally connected to the load-bearing bearing; the conical wheel is sleeved on the pivot shaft, the surface of the conical wheel is a V-shaped groove, and the winding roller is placed on the surface of the V-shaped groove.

[0022] By adopting the above technical solution, the contact area between the winding roller and the V-shaped groove is small, thereby reducing the friction and making it easier for the winding roller to rotate. When the moving body needs to be separated from the winding roller, the moving body is pulled to move the conical wheel along the winding roller, thereby separating from the winding roller.

[0023] A method for producing a stainless steel strip comprises the following steps: Material selection, incoming material inspection, and rewinding on the rewinder; One-time rolling; One cleaning; Solution treatment; Secondary rolling; Secondary cleaning; Pull and straighten; Cutting and packaging.

[0024] By adopting the above technical solution and the production method of stainless steel strip, the forming of the stainless steel strip can achieve the requirements of high hardness and high elongation, and the process control is relatively simple, the cost is low, and it is conducive to large-scale production.

Furthermore, when a device is said to "include" a certain component, unless otherwise stated, this does not exclude the inclusion of other components but rather implies that the device may include other components.

[0032] The following is combined with Figure 1 -Attached Figure 7 , further details of this application are given.

[0033] The embodiments of the present application disclose a stainless steel strip rewinder and a production method.

[0034] A stainless steel strip rewinder, reference Figure 1 As shown, it includes a driving body 1, a moving body 2, a receiving base 3 and a pressing mechanism 4; the driving body 1 serves as the connection point of the entire machine, and is provided with a driving mechanism 5 for providing winding drive. The driving mechanism 5 provides the driving function of winding. Sensors and controllers can also be set on the driving body 1 to detect the accuracy of the winding position, such as photoelectric sensors, distance sensors, etc., so that when the steel strip is wound, the position offset can be detected by the sensor to improve the accuracy of the winding. The controller provides a receiving signal and issues a control instruction.

[0035] The mobile body 2 is provided with a winding roller 21 for winding the steel strip. The steel strip is wound on the winding roller 21. The winding roller 21 is detachably connected to the driving mechanism 5, so that when the winding roller 21 is driven by the driving mechanism 5, it can drive the steel strip to be wound, thereby achieving the effect of rewinding. The mobile body 2 provides lifting and movement of the wound steel strip coil. The mobile body 2 can move along the moving ground or along a fixed track, and can also provide lifting so that the wound steel strip coil can be placed.

[0036] The pressing mechanism 4 is installed on the driving body 1 and contacts the steel strip being wound. The pressing mechanism 4 is used to compact the continuously wound steel strip during the winding process, thereby ensuring the stability of the steel strip and the accuracy of the winding position during winding.

[0037] The receiving base 3 is arranged below the mobile body 2, and the mobile body 2 drives the steel strip roll to the receiving base 3, and the steel strip roll is placed on the receiving base 3 through the lifting action, so that the receiving base 3 receives the steel strip roll. After the steel strip roll is released, the bottom of the receiving base 3 can be provided with moving wheels, universal wheels and other moving structures, and the universal wheels and other moving structures have their own locking structures to ensure that the receiving base 3 is stably placed when it does not need to be moved. The moving structure can cooperate with the receiving base 3 to transport the steel strip roll, and the mobile body 2 can return to the driving body 1, and the winding roller 21 is connected to the driving mechanism 5, so that the next group of steel strips can be rewound.

[0038] Among them, the ground or working plane at the receiving base 3 can be provided with a positioning groove for placing the receiving base 3, so as to facilitate the placement of the receiving base 3. At the same time, the receiving base 3 can be conveniently pushed out of the positioning groove by a movable structure such as a movable wheel. Since the receiving base 3 can be moved by the movable structure, the specific position of the receiving base 3 is not limited and can be moved to a designated position according to needs.

[0039] Specifically, after the steel strip is wound on the winding roller 21, the driving mechanism 5 drives the winding roller 21 to rotate, thereby driving the steel strip to be wound and gradually forming a steel strip coil. During the winding process, the pressing mechanism 4 contacts the steel strip and applies pressure to the steel strip to lower the winding roller 21, so that the steel strip is compacted and the steel strip is rewound tightly during winding. After winding, the mobile body 2 drives the winding roller 21 to separate from the driving mechanism 5, and at the same time moves to the receiving base 3. The lifting action of the moving mechanism is used to lower the steel strip coil and place it on the receiving base 3, so as to achieve a stable and tight rewound steel strip coil and facilitate the recovery of the rewound steel strip coil.

[0040] For further reference, Figure 1 and Figure 2 As shown, the driving mechanism 5 includes a driving motor 51, a driving shaft 52 and a locking structure 53; the driving motor 51 is connected to the driving body 1, the driving motor 51 is embedded in the driving body 1, and extends a driving shaft 52 to provide drive.

[0041] One end of the drive shaft 52 is connected to the drive motor 51 in the drive body 1, and the other end is connected to the locking structure 53. The connection method is a fixed connection. Since the locking structure 53 is installed on the drive shaft 52, the winding roller 21 only needs to be connected to the locking structure 53 to be driven by the drive shaft 52. The locking structure 53 is used to lock the winding roller 21 with the drive shaft 52. The locking structure 53 and the winding roller 21 are detachably connected. The detachable connection can be plug-in. When the locking structure 53 is plugged into the winding roller 21, the locking structure 53 is used to fix the plug-in position of the winding roller 21, so that when the drive motor 51 drives the drive shaft 52 to rotate, the locking structure 53 can drive the winding roller 21 to rotate synchronously.

[0042] Further, refer to Figure 1 and Figure 2 As shown, the locking structure 53 includes a locking cylinder 531, which is connected to the drive shaft 52; a plurality of locking grooves 5311 are provided on the inner wall of the locking cylinder 531, and a locking hole 5312 is provided at the end of the locking groove 5311; an ejection hole 211 matching the locking hole 5312 is provided on the outer wall of the winding roller 21, and a connecting plug 212 is provided inside the winding roller 21, and a telescopic groove 2121 is provided in the connecting plug 212, and an ejection spring 213 is provided in the telescopic groove 2121, and a locking protrusion 214 is slidably connected in the ejection hole 211, and the locking protrusion 214 is connected to the ejection spring 213, and the ejection spring 213 provides elastic force for the locking protrusion 214 to eject the ejection hole 211 and the locking hole 5312.

[0043] When the winding roller 21 is plugged into the locking cylinder 531, the locking protrusion 214 passes through the ejection hole 211 and moves along the locking groove 5311 until it moves to the locking hole 5312. The locking protrusion 214 is acted upon by the elastic force of the ejection spring 213 and is stuck into the locking hole 5312 from the locking groove 5311, thereby achieving the locking effect. When it is necessary to separate the winding roller 21 from the locking cylinder 531, the locking protrusion 214 is pressed so that the locking protrusion 214 extends into the locking hole 5312, and the winding roller 21 is pulled, so that the locking protrusion 214 moves along the locking groove 5311 until it is disengaged from the locking groove 5311, completing the locked connection and convenient separation of the winding roller 21 and the locking cylinder 531.

[0044] In some embodiments, reference Figure 3 As shown, the rolling mechanism 4 includes a rolling roller 41, a rolling frame 42, a rolling shaft 43, a receiving frame 44 and a rolling drive unit 45; the rolling drive unit 45 is installed on the driving body 1, and the rolling drive unit 45 can adopt a rolling drive cylinder, hereinafter referred to as the rolling cylinder. During installation, a hinge frame is set on the driving body 1, and the rolling cylinder is hinged to the hinge frame. At the same time, the rolling cylinder is tilted at a preset angle, and the telescopic end of the rolling cylinder is hinged with a conical sleeve 451.

[0045] The receiving frame 44 is installed on the driving body 1 and is provided with a pivot hole. The pressure reel 43 is pivotally connected to the receiving frame 44 through the pivot hole. The receiving frame 44 is used to provide load-bearing function, and the pivot hole is used to prevent the pressure reel 43 from rotating when providing the bearing function. The number of receiving frames 44 can be set to more than two to improve the bearing stability. When more than two are set, the pressure reel 43 passes through all the pivot holes and rotates along the pivot holes.

[0046] The compression roller shaft 43 is connected with the driving end of the compression roller driving part 45, and the driving end of the compression roller driving part 45 is a conical sleeve 451, which is fixedly connected with the compression roller shaft 43, so that when the extension end of the compression cylinder pushes or pulls the conical sleeve 451, the compression roller shaft 43 rotates along the pivot hole.

[0047] The compression roller frame 42 is installed on the compression roller shaft 43, and the compression roller 41 is pivotally connected with the compression roller frame 42. When the compression roller frame 42 rotates with the compression roller shaft 43, it drives the compression roller 41 to contact the steel strip roll and apply pressure to the steel strip roll. When the steel strip roll rotates with the winding roller 21, it contacts the steel strip roll, so it rotates along the compression roller frame 42 synchronously.

[0048] Specifically, the compression roller driving part 45 drives the compression roller shaft 43 to rotate along the supporting frame 44 through the pivot hole, and drives the compression roller frame 42 to rotate in the process of rotation. The compression roller 41 is located on the compression roller frame 42, so it contacts the steel strip roll during the movement of the compression roller frame 42, so that the compression roller 41 can apply pressure to the steel strip roll, thereby providing a stable compression effect to the steel strip roll during rewinding, to ensure the accurate and stable position of the steel strip roll after rewinding.

[0049] In some embodiments, referring to Figure 4 As shown, the driving body 1 is also provided with a pressure increasing mechanism 6, which is connected with the compression mechanism 4. The pressure increasing mechanism 6 is used to provide pressure to the steel strip roll. As the steel strip roll is continuously rewound, the cross section of the steel strip roll will increase, that is, the diameter of the steel strip roll will continuously increase with the rewinding. The pressure of the compression mechanism 4 on the continuously increasing steel strip roll will change, so the pressure increasing mechanism 6 is provided to balance the pressure on the steel strip roll.

[0050] Further, referring to Figure 4 As shown, the pressure increasing mechanism 6 includes a fixed part 61, an extension cylinder 62, an elastic part 63 and a sensing part 64. The fixed part 61 is connected with the driving body 1. The fixed part 61 can be a fixed cylinder or a fixed frame. In this embodiment, the fixed cylinder is taken as an example. When the fixed cylinder is used as the fixed part 61, the fixed cylinder can cover the locking cylinder 531. The extension cylinder 62 is connected with the outer wall of the fixed part 61. The connection mode can be bolted. The locking seat is provided at the bottom of the extension cylinder 62, and the locking is realized by bolts.

[0051] The sensing part 64 is installed on the roll pressing frame 42. The sensing part 64 can adopt a pressure sensor. One end of the elastic part 63 is hinged to the telescopic cylinder 62, and the other end is hinged to the sensing part 64. The elastic part 63 can adopt a spring. The sensing part 64 mainly provides the pulling force value of the elastic part 63 on the sensing part 64. The sensing part 64 is pre-set with a threshold range of a preset value. When the pulling force is in a pre-set range less than or greater than the preset value, the sensing part 64 will send an electrical signal to the controller, and the controller will send a control instruction to the telescopic cylinder 62. The telescopic cylinder 62 will be extended and retracted to adjust the distance between the elastic part 63 and the sensing part 64, thereby adjusting the pulling force of the elastic part 63 on the sensing part 64.

[0052] A signal transceiver may also be provided on the telescopic cylinder 62 , and the electrical signal of the sensing portion 64 may be directly sent to the telescopic cylinder 62 to directly control the extension and retraction of the telescopic cylinder 62 .

[0053] Specifically, as the steel strip roll is continuously wound, when the clamping mechanism needs to provide stable pressure on the steel strip roll, the elastic part 63 generates tension to pull the pressing frame 42 through the sensing part 64, so that the pressing frame 42 and the clamping roller increase the pressure on the steel strip roll. Subsequently, as the steel strip roll continues to grow, the pressing frame and the pressing roller 41 move synchronously, so that the elastic part 63 is stretched, thereby generating a greater tension. Therefore, the sensing part 64 senses that the tension is greater than the preset value, causing the telescopic cylinder 62 to extend, thereby reducing the tension of the elastic part 63 to the preset value, and repeating this process to achieve a boosting effect of providing a stable pressure value to the pressing mechanism 4.

[0054] In some embodiments, reference Figure 1 and Figure 4 As shown, the mobile body 2 includes a first mobile seat 22, a second mobile seat 23, a lifting cylinder 24, a pivot platform 25 and a disengagement cylinder 26; the first mobile seat 22 and the second mobile seat 23 are support platforms for the winding roller 21. When the winding roller 21 is rewinding the steel coil, the pressure it receives will be directly transmitted to the first mobile seat 22 and the second mobile seat 23.

[0055] A movable rail or movable chute (not shown in the figure) can be set on the ground or work plane. The movable rail or movable chute extends to the driving body 1. The movable rail or movable chute provides a fixed moving path for the first movable seat 22 and the second movable seat 23, so that the first movable seat 22 and the second movable seat 23 can move accurately when moving, and also increases the connection accuracy between the winding roller 21 and the locking structure 53.

[0056] The first movable seat 22 and the second movable seat 23 are both provided with a rolling portion 27 at the bottom, and are slidingly connected to the movable rail through the rolling portion 27. The rolling portion 27 can be a slider, or preferably a roller. The roller has less friction than the slider, so it can more conveniently move the first movable seat 22 and the second movable seat 23.

[0057] The first moving seat 22 and the second moving seat 23 are both provided with a lifting cylinder 24, which is used to drive the winding roller 21 to lift and descend with the steel strip coil, so as to place the steel strip coil and the winding roller 21 on the receiving base 3 by lifting. The lifting cylinder 24 can be embedded in the first moving seat 22 and the second moving seat 23. The top of the lifting cylinder 24 is provided with a pivoting table 25, and the winding roller 21 is pivotally connected with the pivoting table 25. The winding roller 21 is placed on the pivoting table 25, and the pivoting table 25 ensures that the winding roller 21 can stably rotate.

[0058] The disengaging cylinder 26 is connected with the second moving seat 23, and the driving end is connected with the driving body 1. When the telescopic end of the disengaging cylinder 26 is elongated, the second moving seat 23 can be pushed to move, so that the winding roller 21 on the second moving seat 23 is disengaged from the locking structure 53.

[0059] As shown in the reference Figure 5 The first moving seat 22 and the second moving seat 23 can be provided with a separable connecting frame 29. The connecting frame 29 can be connected in a plug-in manner. For example, the first moving seat 22 and the second moving seat 23 are provided with clamping grooves on opposite surfaces. The connecting frame 29 is in the shape of an inverted L-shaped frame, and at least two groups of connecting frames 29 can be provided. The two ends of the connecting frame 29 are respectively inserted into the clamping grooves of the first moving seat 22 and the second moving seat 23, so that the plug-in connection is completed. When the second moving seat 23 is pushed by the disengaging cylinder 26, the first moving seat 22 can be simultaneously pushed. When it is necessary to separate the first moving seat 22 and the second moving seat 23, the connecting frame 29 can be taken out of the clamping grooves, so that any moving seat can be pushed to separate the two moving seats. When separated, it is convenient to disengage the winding roller 21, so as to facilitate workers to take out the winding roller 21 on the first moving seat 22 and the second moving seat 23.

[0060] As shown in the reference Figure 6 The outer wall of the driving body 1 is further provided with a limiting cylinder 28, and the telescopic end of the disengaging cylinder 26 is further provided with a linkage rod 262, which is inserted into the limiting cylinder 28 and slides along the limiting cylinder 28. The telescopic end is connected with a limiting plate 261, and the size of the limiting plate 261 is greater than the cylinder diameter of the limiting cylinder 28, so that the limiting plate 261 cannot be disengaged from the limiting cylinder 28.

[0061] A limiting groove 611 is provided on the inner wall of the fixing portion 61, and a sliding opening 612 is provided on the outer wall. An unlocking ring 613 is also provided in the fixing portion 61, which is slidably connected to the limiting groove 611 and the sliding opening 612. The linkage rod 262 passes through the sliding opening 612 and is connected to the unlocking ring 613. When it is necessary to connect the winding roller 21 with the locking cylinder 531, the telescopic end of the disengagement cylinder 26 contracts, so that the limiting plate 261 contacts the cylinder mouth of the limiting cylinder 28, thereby applying a pulling force to the limiting cylinder 28, causing the second movable seat 23 to move toward the locking cylinder 531, and the winding roller 21 can be inserted into the locking cylinder 531 until the locking protrusion 214 is stuck in the locking hole 5312, completing the locking.

[0062] When the steel strip coil is rewound, the locking effect needs to be released, and the telescopic end of the disengagement cylinder 26 moves toward the driving body 1 along the limit cylinder 28. During the movement, the linkage rod 262 is driven to move, and the linkage rod 262 drives the unlocking ring 613 to move along the sliding opening 612. The unlocking ring 613 presses down the locking protrusion 214, so that the locking protrusion 214 returns to the locking hole 5312 and the locking groove 5311. Then the telescopic end of the disengagement cylinder 26 contacts the driving body 1 and pushes the driving body 1. The reaction force moves the second movable seat 23 away from the driving body 1, and simultaneously separates the winding roller 21 that has lost the locking effect of the locking protrusion 214 from the locking cylinder 531 to achieve the effect of integrated unlocking.

[0063] For further reference, Figure 7 As shown, the pivot platform 25 includes a load-bearing bearing 251, a pivot shaft 252 and a conical wheel 253; a lifting platform is provided on the top of the upgrading cylinder to provide installation for the load-bearing bearing 251, and there are two groups of load-bearing bearings 251, which are respectively located on both sides of the lifting platform of the lifting cylinder 24. The pivot shaft 252 is pivotally connected to the load-bearing bearings 251, and the pivot shaft 252 can rotate along the two load-bearing bearings 251. At the same time, the lifting cylinder 24 can also drive the load-bearing bearings 251 to rise and fall.

[0064] The conical wheel 253 is sleeved on the pivot shaft 252. The conical wheel 253 is composed of two sets of relatively contacting conical structures, such as ∞ shape, so that the surface of the conical wheel 253 is a V-shaped groove. The winding roller 21 is placed on the V-shaped groove surface of the conical wheel 253, and then a pivot shaft 252 is provided to enable the conical wheel 253 to rotate along the load-bearing bearing 251. Due to the V-shaped groove of the conical wheel 253, the contact area between the winding roller 21 and the V-shaped groove is small, thereby reducing the friction and making it easier for the winding roller 21 to rotate. When the mobile body 2 needs to be separated from the winding roller 21, the mobile body 2 is pulled to move the conical wheel 253 along the winding roller 21, thereby separating from the winding roller 21.

[0065] Further, refer to Figure 7As shown, the load bearing bearing 251 is also provided with a pivot frame 254 away from one end of the conical wheel 253, and the pivot frame 254 is pivotally connected with the guard frame 255, the guard frame 255 adopts an H-shaped frame body, both sides are provided with a socket, the socket is pivotally connected with the pivot frame 254, the guard frame 255 can rotate along the pivot frame 254 through the socket, and the position is switched during the rotating process, and the winding roller 21 can be switched to be separated from the path, so as to block the winding roller 21, so as to avoid the position deviation of the winding roller 21 in the winding process, and the winding roller 21 can also be switched in the vertical direction, so that the disengagement path of the winding roller 21 is opened, so as to ensure the separation effect of the winding roller 21 and the conical wheel 253.

[0066] Wherein, the surface of the load bearing bearing 251 is also provided with a limiting block 256 to limit the rotating path of the guard frame 255, so as to avoid the friction damage caused by the too large rotating amplitude and the contact with the winding roller 21.

[0067] The application also provides a production method of stainless steel strip, which comprises the following steps: S100, selecting material, feeding inspection, re-coiling by the above-mentioned re-coiler, checking surface problems, simultaneously adding a sleeve of inner ring, and re-coiling the irregular steel coil which is not re-coiled; High-silicon molybdenum SUS301 of TISCO stainless steel is selected, or 12Cr17Ni7SiMo is added on the basis of 301 austenitic stainless steel strip, and the thickness of the blank is 1.0 mm; S200, primary rolling, cold rolling mill rolling, symmetrical on both sides, back and forth pressing, a plurality of rollers in the middle, selecting single rolling process deformation according to the thickness requirement of the finished product, and rolling the raw material thickness in multiple passes to directly roll to the semi-finished product thickness; Wherein, during the primary rolling, the single rolling process deformation is selected according to the thickness requirement of the finished product, the raw material thickness is rolled in multiple passes to directly roll to the semi-finished product thickness, and the deformation of the primary rolling is 20% to 30%. Through such multiple-pass rolling, the deformation can be more accurately controlled, and the influence of excessive deformation on the performance of the steel strip is avoided.

[0068] S300, primary cleaning, the surface oil stains are cleaned by an alkali cleaning machine, then high-temperature hot water cleaning is performed, and finally drying and coiling are performed, the rolled semi-finished product is removed from the rolling oil remaining on the surface of the steel strip in a degreasing cleaning machine group, and preparation is made for solid solution treatment; if the continuous annealing line includes a cleaning section, this process can be omitted; Wherein, the cleaning tank of the cleaning machine can be made of stainless steel, which is corrosion-resistant and easy to clean, or a plastic cleaning tank can be selected, which is low in cost and light in weight.

[0069] S400, solid solution treatment Carry out solid solution treatment under the protection of pure hydrogen or ammonia decomposition gas; pass the semi-finished steel strip after one cleaning through the annealing furnace; Among them, the solid solution treatment is to pass the semi-finished steel strip that has undergone one rolling through an annealing furnace and is carried out under the protection of inert gas. The inert gas can be pure hydrogen or ammonia decomposition gas. These inert gases can prevent the steel strip from being oxidized during the solid solution treatment process and ensure that the internal structure of the steel strip is not disturbed by external factors. The solid solution treatment temperature is 1050℃ to 1150℃. Within this temperature range, the alloy elements in the steel strip can be fully dissolved to form a uniform austenite structure, thereby improving the overall performance of the steel strip. The annealing furnace can be a resistance-heated annealing furnace, which has uniform heating and precise temperature control. A gas-heated annealing furnace can also be used, which has a fast heating speed and can improve production efficiency.

[0070] S500, secondary rolling According to the thickness requirements of the finished product, it is rolled in multiple passes until it is finally rolled into the finished product; The deformation during the secondary rolling process ranges from 15% to 25%, and is less than that during the primary rolling process. This deformation setting ensures that the steel strip's hardness is further increased while maintaining its elongation. The operating principle of a cold rolling mill is similar to that of the primary rolling process, with the rollers rolling the solution-treated semi-finished steel strip.

[0071] S600, secondary cleaning The finished steel strip is removed from the surface of the steel strip during rolling in the degreasing and cleaning unit to prepare for straightening, so as to ensure the quality of straightening treatment and avoid the adverse effects of rolling oil on the straightening process; S700, tension leveler The cleaned finished steel strip is corrected on the tension and leveling machine. Small tension and small pressure are used to improve the shape. It is strictly forbidden to correct the shape with large elongation, so as not to affect the elongation of the finished product. Among them, the tension straightening treatment uses a tension straightening machine, which improves the plate shape by applying a small tension and a small reduction to the finished steel strip. The tension of the tension straightening treatment is less than 0.3MPa and the reduction is less than 0.03mm / mm. This small tension and small reduction method can avoid the influence of large elongation tension straightening on the elongation of the finished product.

[0072] The rollers of the straightening machine can be polyurethane-coated rollers, which have good elasticity and wear resistance, can better contact with the steel belt and achieve plate shape correction. Rubber-coated rollers can also be used, which can also achieve good correction effects.

[0073] S800, cutting and packaging Cut, pack and store according to customer requirements.

[0074] The dividing and shearing device can adopt a disc shearing machine, which has high shearing precision and can meet the requirements of dividing and shearing of steel strips with different sizes. A guillotine shearing machine can also be selected, which is suitable for dividing and shearing of some thick steel strips. The packaging material can be plastic film and paper packaging, which can protect the surface of the steel strip and prevent moisture.

[0075] The dividing and shearing packaging step can make the finished steel strip meet the different needs of customers, facilitate transportation and storage, and improve the market adaptability of the product.

[0076] The embodiments of the specific embodiment are the preferred embodiments of the application, not limited to the protection scope of the application, wherein the same parts are indicated by the same reference numerals. Therefore, any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
