Description

Technical Field

[0001] The present invention relates to a coiling device for strip steel production in the field of steel products, specifically a vertical coiling device and coiling method for strip steel. Background Art

[0002] Strip steel is a kind of steel product with a strip shape among various steels. It is a coiled steel supplied with a width within 1300 mm and a length slightly different according to the size of each coil. Strip steel has the characteristics of high strength, good toughness, high dimensional accuracy, and strong workability, and is widely used in fields such as construction, automobile manufacturing, machinery manufacturing, household appliance manufacturing, electronic information, energy chemical industry, and daily necessities.

[0003] Strip steel is generally produced by hot rolling or cold rolling processes. Hot-rolled strip steel is rolled into strip steel with the required thickness and width through a hot rolling mill after heating a steel billet to a certain temperature; cold-rolled strip steel is further cold-rolled on the basis of hot-rolled strip steel to obtain higher dimensional accuracy, surface quality, and better mechanical properties.

[0004] In the prior art, since cold-rolled strip steel does not involve heating problems, during the coiling process after cold rolling, horizontal coiling is generally adopted, that is, the strip steel moves flat on the conveyor rollers and is coiled into a steel coil by a coiling machine;

[0005] In the production of hot-rolled strip steel, the steel billet needs to be heated to a certain temperature first and then rolled by a hot rolling mill. During the whole rolling process, the strip steel remains at a relatively high temperature. After rolling is completed, cooling means need to be used to reduce the temperature of the strip steel to a certain extent before coiling can be carried out. In order to improve the cooling efficiency, after the hot-rolled strip steel comes out of the hot rolling mill, it is generally flipped so that its surface is perpendicular to the conveyor rollers. At this time, cooling devices such as water cooling and air cooling arranged on both sides cool the two side surfaces of the strip steel at the same time, and the temperature reduction and cooling of the strip steel can be achieved as quickly as possible within a limited production site.

[0006] Since the strip steel is perpendicular to the conveyor rollers at this time, the device for coiling it into a strip steel coil is called a vertical coiling machine; the core of the vertical coiling machine is a rotatable drum, and the central axis of the drum is perpendicular to the ground. At this time, the end of the strip steel needs to be clamped into the card slot on the drum, and then the coiling machine is started to rotate the drum to complete the coiling of the strip steel.

[0007] Since the strip is vertical at this time, that is, perpendicular to the conveyor rollers, the contact friction between the two is very small. Relying solely on the frictional force between the conveyor rollers and the strip cannot move the strip forward to the reel. Moreover, the positions of the ends of different strips on the conveyor rollers are also different. And the entire working area has high temperature and humidity, and some precision electronic components are not suitable for this environment. Considering the cost, generally, the end of the strip is manually pulled into the card slot of the reel; however, because the temperature of the strip is still relatively high at this time, and after coming out of the hot rolling mill, the initial speed of the strip is also very high, the risk of operation is relatively high when workers manually pull the end of the strip into the card slot of the reel, and industrial accidents are likely to occur. Summary of the Invention

[0008] In order to solve the problem of high operation risk and easy occurrence of industrial accidents caused by manually pulling the end of the steel strip into the card slot of the reel when the existing hot-rolled strip is vertically coiled, the present invention provides a vertical winding device and winding method for a steel strip. The vertical winding device realizes finding the strip head from the disordered strips through a unique strip clamping mechanism, and through the cooperation of the guiding part and the guiding plate, automatically clips it into the card slot of the lifting reel. During the whole process, the manual operation only plays the role of positioning the guiding plate and the card slot, and the operation process occurs before coiling the strip, thus greatly reducing the operation risk; moreover, the equipment used in the present invention are all conventional equipment of the existing technology, and the procurement cost and the later maintenance cost are also relatively low.

[0009] The technical solution adopted by the present invention to solve the above technical problems is: a vertical winding device for a steel strip, the winding device includes a coiling table in front of the strip conveyor, and a lifting reel capable of descending and extending out of the surface of the coiling table is arranged at the center of the coiling table. At least one card slot for clamping the end of the strip is arranged on the lifting reel along its height direction. A guiding part is arranged between the coiling table and the strip conveyor. The guiding part includes a guiding groove formed between two relatively arranged plate-like members. The end of the guiding groove close to the strip conveyor has a clamping power roller with a pair of rollers. One end of the guiding groove close to the coiling table is hinged with a guiding plate, and the guiding plate adjusts its position through a hand-operated lever, and its free end can be clamped on one side of the card slot of the lifting reel; a strip clamping mechanism for clamping the strip and guiding it to the clamping power roller is arranged at the end of the strip conveyor.

[0010] As an optimized solution for the above vertical winding device for strip steel, the strip steel clamping mechanism includes lifting and moving components on both sides at the end of the strip steel conveyor. The lifting and moving components include horizontal guide rails and longitudinal sliders sliding along the horizontal guide rails. Lifting guide rails are vertically arranged on the longitudinal sliders, and lifting sliders are arranged on the lifting guide rails. A cross beam is arranged between the two lifting sliders. A transverse lead screw and two clamping sliders driven by the transverse lead screw to separate and close are provided on the cross beam. A rotating shaft driven by a motor to rotate is provided below each clamping slider, and a clamping roller for clamping the strip steel is provided at the bottom of the rotating shaft.

[0011] As another optimized solution for the above vertical winding device for strip steel, the free end of the guide plate has an extension part. One side of the extension part has a convex part with an angle of 90 - 120° with it, and a clamping platform structure capable of being inserted into the card slot is formed between the convex part and the extension part.

[0012] As another optimized solution for the above vertical winding device for strip steel, a limit plate is fixedly arranged at one end of the guiding groove close to the coiling table. The limit plate and the guide plate are respectively on both sides of the end of the guiding groove, and the end of the limit plate extends to one side of the guide plate, and a gap is formed between the two.

[0013] As another optimized solution for the above vertical winding device for strip steel, gathering plates are arranged on both sides of the clamping power roller, and the two gathering plates are arranged in a V shape.

[0014] As another optimized solution for the above vertical winding device for strip steel, a cylindrical cavity is arranged at the center of the coiling table. The lifting winding drum is arranged in the cylindrical cavity and is driven by a lifting structure at its bottom to extend to the surface of the coiling table or completely retract into the cylindrical cavity. After the lifting winding drum extends to the limit position, it can be connected to the coiling table and rotate synchronously with the coiling table.

[0015] As another optimized solution for the above vertical winding device for strip steel, the lifting winding drum is fixedly connected to the lifting structure through a slewing mechanism. The slewing mechanism includes a fixed part and a rotating part that can rotate relative to each other. The bottom surface of the fixed part is fixedly connected to the lifting structure, and the rotating part is rotatably arranged above the fixed part through a central rotating shaft.

[0016] As another optimized solution for the above vertical winding device for strip steel, a plurality of locking mechanisms are arranged around the side wall of the rotary mechanism. Each locking mechanism includes a clamping strip slidably arranged in a counterbore on the side wall of the rotating part. One end of the clamping strip is fixed to a compression spring arranged in the counterbore, and the other end is an inclined slope. A locking hole is arranged on the inner wall of the cylindrical cavity of the coiling table at the lifting and lowering trajectory of the clamping strip. During the rising process of the clamping strip, it can be pushed by the compression spring and clamped into the locking hole to realize the locking of the rotating part and the coiling table. Or, during the descending process of the clamping strip, the inclined slope of the clamping strip can slide out of the locking hole to realize the separation of the rotating part and the coiling table.

[0017] As another optimized solution for the above vertical winding device for strip steel, a toothed ring is arranged at the edge of the coiling table, and the toothed ring meshes with the toothed ring at the edge of the driving wheel disc arranged on one side of the coiling table.

[0018] A method for winding strip steel using the above vertical winding device for strip steel includes the following steps:

[0019] 1) Workers drive the guide plate to move by using a hand-held operating rod and make the free end of the guide plate snap into one side of one of the card slots. At this time, the guide plate remains in an arc shape, and the exposed part of the card slot and the guiding groove are on the same side of the guide plate at the same time.

[0020] 2) Start the lifting and moving assembly to move the cross beam to a position above the strip steel. Then, make the lifting slider drive the cross beam to descend until the clamping rollers below the clamping slider are on the side of the strip steel. Then start the transverse lead screw to make the two clamping sliders gradually move closer to the middle of the cross beam until the two clamping rollers clamp both sides of the strip steel.

[0021] 3) Start the motor to drive the two clamping rollers to rotate by the two rotating shafts. Due to the existence of friction, the strip steel moves relative to the clamping rollers until the position near the head of the strip steel moves between the two clamping rollers.

[0022] 4) Start the lifting and moving assembly to move the cross beam to the clamping power roller. Start the motor again to make the clamping rollers rotate to drive the strip steel to move forward and enter the clamping power roller. At this time, start the transverse lead screw to make the two clamping sliders move in opposite directions to both sides of the cross beam. Then make the lifting slider drive the cross beam to rise. While the cross beam is rising, the lifting and moving assembly moves along the horizontal guide rail to the initial position.

[0023] 5) The clamping power roller clamps and drives the strip steel to move forward along the guiding groove. After passing through the guiding groove, it is blocked by the guide plate and moves on the surface of the guide plate to the card slot.

[0024] 6) Workers use the hand-held operating rod to take out the guide plate from the card slot and make the guide plate move out of the range of the coiling table, and then start the coiling table to wind.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1) The present invention realizes finding the strip head from the disordered strip through a unique strip clamping mechanism, and through the cooperation of the guiding part and the guiding plate, automatically clamps it into the clamping groove of the lifting reel. During the whole process, the manual work only plays the role of positioning the guiding plate and the clamping groove, and the operation process occurs before coiling the strip, thus greatly reducing the operation risk; The equipment used in the present invention are all conventional equipment of the prior art, with low procurement cost, and are fully adapted to the operation in high-temperature and high-humidity environments, and the later maintenance is very convenient and low-cost;

[0027] 2) The present invention creatively uses two clamping rollers that can be separated and closed to clamp any part of the strip, and then uses the forward and reverse rotation of the clamping rollers to find the strip head and send the strip head into the guiding part, so that it automatically enters the clamping groove along the guiding groove and the guiding plate, realizing the operations of automatically finding the head, aligning, and clamping in the disordered strip, and greatly improving the operation safety.

[0042] Embodiment 1

[0043] A vertical winding device for strip steel, as shown in Figure 1 and 2As shown in the figure, the coiling device includes a coiling table 1 in front of the strip conveyor 9. The strip conveyor 9 is an existing chain plate conveyor. After hot rolling, the strip is in a vertical state on the strip conveyor 9. By "vertical state", it means that its surface is in a vertical state. At the center of the coiling table 1, there is a lifting drum 3 that can descend and extend out of the surface of the coiling table 1. When the lifting drum 3 descends to the limit position, the whole lifting drum 3 is located below the position of the coiling table 1, so as not to affect the movement of the coiled strip coil that has been coiled; when the lifting drum 3 rises to the limit position, the whole lifting drum 3 is on the surface of the coiling table 1 and can be locked and fixed with the coiling table 1, and the two rotate synchronously, so that the strip can be coiled on its side surface. Along the height direction of the lifting drum 3, there is at least one card slot 301 for clamping the end of the strip. The card slot 301 is strip-shaped and is vertically arranged on the side surface of the lifting drum 3. Its length is greater than the width of the strip, so that the end of the strip can be easily clamped into the card slot 301. The width of the card slot 301 is greater than the width of the free end of the guiding plate 8, so that when the free end of the guiding plate 8 is clamped on one side wall of the card slot 301, the remaining part of the card slot 301 can still allow the strip to be easily clamped into it. A guiding part 7 is arranged between the coiling table 1 and the strip conveyor 9. The length of the guiding part 7 is designed according to the actual situation. The guiding part 7 includes a guiding groove 701 formed between two relatively arranged plate-shaped members. The plate-shaped members can be straight plates or arc-shaped plates, so that the guiding groove 701 forms a variable-diameter groove with a large width at both ends and a small width in the middle. The depth of the guiding groove 701, that is, the height of the plate-shaped member, is generally 20-80% of the width of the strip; the width of the guiding groove 701 is selected according to the actual situation, generally 3-10 cm. One end of the guiding groove 701 close to the strip conveyor 9 has a clamping power roller 702 with a pair of rollers. The clamping power roller 702 is driven by existing power to rotate, and drives the strip to move forward by friction during rotation. The moving speed of the strip head is controlled by controlling the rotation speed of the clamping power roller 702. One end of the guiding groove 701 close to the coiling table 1 is hinged with a guiding plate 8. The height of the guiding plate 8 is generally not less than 50% of the width of the strip. The material is generally selected as an elastic thin steel plate and should be as light as possible for easy operation. One side of the guiding plate 8 is fixedly arranged on a vertical shaft, and the vertical shaft is fixed on the ground on one side of the guiding groove 701 through a bearing. And the center of the lifting drum 3 and the vertical shaft are on both sides of the guiding groove 701. The center of the lifting drum 3 avoids the position directly opposite to the guiding groove 701. In practice, the position directly opposite to the guiding groove 701 is on one side of the coiling table 1, and the guiding plate 8 adjusts its position through a handheld operating rod 801, and its free end can be clamped on one side of the card slot 301 of the lifting drum 3. The handheld operating rod 801 is a rod-shaped member hinged to the free end of the guiding plate 8. The length is determined according to the actual situation, generally about 1 m. When the end of the guiding plate 8 is clamped in the card slot 301, the guiding plate 8 is generally in an arc-shaped bending state;A strip clamping mechanism for clamping the strip and guiding it to the clamping power roller 702 is provided at the end of the strip conveyor 9;

[0044] In this embodiment, the strip clamping mechanism includes lifting and moving components 4 on both sides of the end of the strip conveyor 9. As Figure 4 shown, the lifting and moving component 4 includes a horizontal guide rail 401 extending along the transmission direction of the strip conveyor 9 and crossing its end to extend into the gathering area, and a longitudinal slider 402 sliding along the horizontal guide rail 401. In practice, the longitudinal slider 402 has its own power, such as a motor, to control its reciprocating movement on the horizontal guide rail 401. Limit blocks 405 are provided at both ends of the horizontal guide rail 401 to prevent the longitudinal slider 402 from detaching from the horizontal guide rail 401. A lifting guide rail 403 is vertically provided on the longitudinal slider 402. In practice, the lifting guide rail 403 is selected as a lead screw, and the drive motor of the lead screw is generally provided on the longitudinal slider 402. A lifting slider 404 is provided on the lifting guide rail 403. The lifting slider 404 and the lifting guide rail 403 form an existing lead screw-slider mechanism. A cross beam 5 is provided between the two lifting sliders 404. The cross beam 5 is located above the strip conveyor 9 and is perpendicular to its transmission direction. Both ends are fixed to the two lifting sliders 404, so that the lifting slider 404 drives the cross beam 5 to lift as a whole, and the longitudinal slider 402 drives the cross beam 5 to move along the horizontal guide rail 401 as a whole. The cross beam 5 is provided with a transverse lead screw 501 and two clamping sliders 6 driven by the transverse lead screw 501 to realize separation and closing. Generally, the number of transverse lead screws 501 is two, and they are driven to rotate forward and backward by a lead screw motor 502. The transverse lead screw 501 is divided into left and right parts, and the thread directions of the two parts are opposite. Thus, when the transverse lead screw 501 rotates in one direction, the distance between the two clamping sliders 6 gradually decreases, that is, closing; when rotating in the other direction, the distance between the two clamping sliders 6 gradually increases, that is, separation. A rotating shaft 601 driven by a motor to rotate is provided below each clamping slider 6. The motor is provided on the clamping slider 6, and a clamping roller 602 for clamping the strip is provided at the bottom of the rotating shaft 601. The clamping roller 602 is a metal roller capable of clamping and conveying the strip in the prior art, and its size is small. When the two clamping sliders 6 are closed, the two clamping rollers 602 below them can clamp the strip, and when the rotating shaft 601 rotates in one direction, such as forward rotation, the two clamping rollers 602 drive the strip to move forward, and when the rotating shaft 601 rotates in the other direction, such as reverse rotation, the two clamping rollers 602 drive the strip to move backward;

[0045] In this embodiment, as Figure 3As shown, the free end of the guide plate 8 has an extension 804 extending along its length direction. The thickness of the extension is generally 0.5 - 1 cm, and it is made of a thin steel plate. One side of the extension 804 has a protrusion 803 with an angle of 90 - 120° with it. The protrusion 803 can be several protruding columns or strips distributed along the height direction, or it can be a whole plate-like part. And a snap structure that can be snapped into the card slot 301 is formed between the protrusion 803 and the extension 804. The protrusion 803 and the handheld operating rod 801 are on the same side of the guide plate 8.

[0046] In this embodiment, as Figure 1 and 2 shown, a limiting plate 802 is fixedly arranged at one end of the guiding groove 701 close to the coiling table 1. The limiting plate 802 is also an arc-shaped thin steel plate, and its end should have a certain distance from the edge of the coiling table 1. The limiting plate 802 and the guide plate 8 are respectively on both sides of the end of the guiding groove 701, and the end of the limiting plate 802 extends to one side of the guide plate 8, and a gap is formed between them. The gap is generally 3 - 10 cm.

[0047] In this embodiment, as Figure 1 and 2 shown, gathering plates 703 are arranged on both sides of the clamping power roller 702. The gathering plates 703 are flat steel plates and are vertically placed, with their surfaces perpendicular to the ground. The two gathering plates 703 are arranged in a V-shaped layout, and a gathering area is formed between them. The clamping power roller 702 is at the V-shaped end of the gathering area. The opening width of the gathering area generally corresponds to 30 - 50% of the length at the middle position of the strip conveyor 9.

[0048] A method for winding a strip using the above vertical winding device for strips includes the following steps:

[0049] 1) The worker drives the guide plate 8 to move by using the handheld operating rod 801 and makes its free end snap into one side of one of the card slots 301. At this time, the guide plate 8 remains arc-shaped and bent, and the exposed part of the card slot 301 and the guiding groove 701 are on the same side of the guide plate 8 at the same time;

[0050] 2) Start the lifting and moving assembly 4 to move the cross beam 5 to the position above the strip. Then, make the lifting slider 404 drive the cross beam 5 to descend until the clamping roller 602 below the clamping slider 6 is on the side of the strip. Then start the transverse lead screw 501 to make the two clamping sliders 6 gradually move closer to the middle of the cross beam 5 until the two clamping rollers 602 clamp the two sides of the strip;

[0051] 3) Start the motor to drive the two rotating shafts 601 to drive the two clamping rollers 602 to rotate. Due to the existence of friction, the strip moves relative to the clamping rollers 602 until the position of the strip near the head moves between the two clamping rollers 602;

[0052] 4) Start the lifting and moving assembly 4 to move the crossbeam 5 to the position of the clamping power roller 702. Start the motor again to rotate the clamping roller 602 to drive the strip steel to move forward and enter the clamping power roller 702. At this time, start the transverse lead screw 501 to move the two clamping sliders 6 in opposite directions to both sides of the crossbeam 5, and then make the lifting slider 404 drive the crossbeam 5 to rise. While the crossbeam 5 is rising, the lifting and moving assembly 4 moves along the horizontal guide rail 401 to the initial position.

[0053] 5) The clamping power roller 702 clamps and drives the strip steel to move forward along the guiding groove 701. After passing through the guiding groove 701, it is blocked by the guiding plate 8 and moves on the surface of the guiding plate 8 to the clamping groove 301.

[0054] 6) The worker uses the handheld operating rod 801 to take out the guiding plate 8 from the clamping groove 301. After the guiding plate 8 is separated from the range of the coiling table 1, start the coiling table 1 for coiling.

[0055] Embodiment 2

[0056] This embodiment is a limitation on the structure of the coiling table 1 based on Embodiment 1. The coiling table 1 of the present invention can adopt an existing vertical coiling table 1, or a coiling table 1 with the following structure: As Figures 5 - 9 shown, a gear ring is provided at the edge of the coiling table 1, and this gear ring meshes with the gear ring at the edge of the driving wheel disc 101 provided on one side of the coiling table 1. The driving wheel disc 101 is driven to rotate by conventional power equipment such as a motor and a speed reducer, so as to drive the rotation of the coiling table 1 by relying on the meshing of the gear rings. A cylindrical cavity is provided at the center of the coiling table 1, that is, the coiling table 1 is of an annular structure with a hollow in the middle. At the bottom, through a number of slewing bearing structures, such as the cooperation of balls and tracks, the coiling table 1 can rotate around its center. The lifting drum 3 is arranged in this cylindrical cavity and is driven by the lifting structure 201 at its bottom to extend to the surface of the coiling table 1 or completely retract into the cylindrical cavity. After the lifting drum 3 extends to the limit position, it can be connected to the coiling table 1 and rotate synchronously with the coiling table 1. The lifting structure 201 can be a hydraulically driven lifting rod, or a motor-driven lifting screw, or other similar lifting structures, and its purpose is to be able to drive the overall lifting of the lifting drum 3.

[0057] In this embodiment, as Figures 10 - 12As shown, the lifting drum 3 is fixedly connected to the lifting structure 201 through a slewing mechanism 2. The slewing mechanism 2 includes a fixed part 203 and a rotating part 202 that can rotate relative to each other. Both the fixed part 203 and the rotating part 202 are disc structures, but have a certain thickness. The bottom surface of the fixed part 203 is fixedly connected to the lifting structure 201. For example, when the lifting structure 201 adopts a lifting screw driven by a motor, the bottom surface of the fixed part 203 is fixedly welded to the top end of the lifting screw. The rotating part 202 is rotatably arranged above the fixed part 203 through a central rotating shaft 204. At this time, in order to facilitate the stability of the rotation of the rotating part 202, balls can be arranged in the gap between the rotating part 202 and the fixed part 203, and these balls roll in their specific annular tracks;

[0058] In this embodiment, as Figure 11 and Figure 12 shown, a plurality of locking mechanisms are arranged around the side wall of the slewing mechanism 2. These locking mechanisms are evenly arranged around the side surface of the rotating part 202, and the number is generally 4-8. Each locking mechanism includes a clamping strip 205 slidably arranged in a counterbore on the side wall of the rotating part 202. The counterbore is a horizontal hole opened on the side wall of the rotating part 202, and its axis is in the radial direction of the rotating part 202. The shape of the clamping strip 205 can be rectangular or cylindrical, generally cylindrical, and its size is slightly smaller than the inner diameter of the counterbore to facilitate free sliding. One end of the clamping strip 205 is fixed to a compression spring 206 arranged in the counterbore, and the other end is an inclined slope 207. The inclined slope 207 is formed by cutting off a piece from the end of the clamping strip 205 towards the inner lower side. A locking hole 102 is arranged on the inner wall of the cylindrical cavity of the coiling table 1 on the lifting trajectory of the clamping strip 205. The lower side of the entrance of the locking hole 102 forms an inclined downward slope, and the slope of this slope matches the inclined slope 207. The depth of the locking hole 102 is generally not less than half of the extended length of the clamping strip 205 in the compression spring 206.

10. A method for winding a strip using the vertical winding device for strip steel according to claim 2, characterized in that, It includes the following steps: 1) The worker drives the guide plate (8) to move by using the handheld operating rod (801), and makes the free end of the guide plate (8) snap into one side of one of the clamping slots (301). At this time, the guide plate (8) remains arc-shaped, and the exposed part of the clamping slot (301) and the guiding slot (701) are both on the same side of the guide plate (8). 2) Start the lifting and moving assembly (4) to move the cross beam (5) above the strip steel. Then, make the lifting slider (404) drive the cross beam (5) to descend until the clamping rollers (602) below the clamping slider (6) are on the side of the strip steel. Then, start the transverse lead screw (501) to gradually move the two clamping sliders (6) closer to the middle of the cross beam (5) until the two clamping rollers (602) clamp the two side surfaces of the strip steel. 3) Start the motor to drive the two rotating shafts (601) to drive the two clamping rollers (602) to rotate. Due to the existence of friction, the strip steel moves relative to the clamping rollers (602) until the position of the strip steel near the head moves between the two clamping rollers (602). 4) Start the lifting and moving assembly (4) to move the cross beam (5) to the clamping power roller (702). Start the motor again to drive the clamping rollers (602) to rotate to drive the strip steel to move forward and enter the clamping power roller (702). At this time, start the transverse lead screw (501) to move the two clamping sliders (6) in opposite directions to both sides of the cross beam (5). Then, make the lifting slider (404) drive the cross beam (5) to rise. While the cross beam (5) is rising, the lifting and moving assembly (4) moves along the horizontal guide rail (401) to the initial position. 5) The clamping power roller (702) clamps and drives the strip steel to move forward along the guiding slot (701). After passing through the guiding slot (701), the strip steel is blocked by the guide plate (8) and moves on the surface of the guide plate (8) into the clamping slot (301). 6) The worker takes out the guide plate (8) from the clamping slot (301) by using the handheld operating rod (801). After the guide plate (8) is separated from the coiling table (1), start the coiling table (1) to perform coiling.
