Description

Technical Field

[0001] The present invention relates to the technical field of steel wire processing, in particular to a steel wire drawing process and equipment thereof. Background Art

[0002] Wire drawing is a widely used process in various industries, including steel, nonferrous metals, and plastics. Specifically, wire drawing involves applying tension to a metal blank, forcing it through a die orifice to produce a product of the desired shape and size.

[0003] During the processing of steel wire on the production line, it needs to go through the processes of pay-off, drawing, and winding. During the pay-off process, the original pay-off device directly pulls the steel wire away from the pay-off frame through the traction end because the steel wire is wound on the pay-off frame. At this time, it is easy to pull out the upper and lower layers of steel wire together, thereby getting the wire stuck. When the steel wire is pulled out from the pay-off frame, it is easy to bounce to nearby operators. In addition, the steel wire will undergo a large bending deformation under the action of the traction force and then stick to the pay-off frame when it is paid out, which will have a great impact on the internal structure of the steel wire.

[0004] In addition, during the winding process, a single winding machine is used for winding, and a single winding cannot meet the steel wire to be wound at the front end. That is, after the single winding machine winds a certain amount of steel wire, it needs to stop, cut off the front end steel wire, and then take off the wound steel wire roll, and then wind the front end steel wire through the single winding machine again, which affects the efficiency of steel wire winding.

[0016] A steel wire drawing process is also included, which specifically includes the following steps according to the above-mentioned steel wire drawing equipment: Step 1: Control the telescopic cylinder to drive the limit block to move downward, and the wire coil to be paid out enters through one end of the pay-off rod and moves to one side of the stop frame, and then control the limit block to move upward to limit the pay-off rod; after one end of the wire coil passes around the stop frame, it passes through the wire blocking wheel group on the first bracket, the wire blocking wheel group on the second bracket, the guide block and the guide wheel to the inside of the hollow column, and then is connected to the wire drawing machine, the heating furnace, the rapid cooling pool and the lubrication groove in sequence through the wire blocking wheel group on the shaft seat, and the drive motor is started. The drive motor drives the hollow column to rotate through the first pulley, the second pulley and the first transmission belt. The rotation of the hollow column drives the wire coil to pay out; Step 2: After the steel wire extends from the hollow column, it enters the multi-pass wire drawing machine for drawing, then enters the heating furnace for heating, enters the rapid cooling pool for cooling, and is oiled in the lubrication tank before being taken up by the take-up device; Step 3: The front end steel wire continuously passes through the guide through hole in the movable seat while the pay-off device, wire drawing machine, heating furnace, rapid cooling pool and lubrication groove are working without stopping, and then passes through one of the cutting through holes and one of the guide tubes in turn to one of the winders. When the winder needs to wind the steel wire, the reduction motor below is started, and the reduction motor drives the winding turntable to rotate through the first transmission wheel, the second transmission wheel, the second transmission belt and the transmission shaft. After the steel wire extends from the inclined tube section, it is transported between the long positioning tube and the short positioning tube. As the steel wire is continuously transported, the winding turntable is driven to rotate, and the steel wire is wound between the long positioning tube and the short positioning tube to form a wire coil. When the above-mentioned winder is full of steel wire, the cutting switching mechanism is controlled to start another winder at the same time. The cutting switching mechanism drives the movable seat to move. While the steel wire is being cut, one end of the front steel wire moves in the movable seat to the side of another cutting through hole in the fixed seat, and is transported along the inside of the cutting through hole and another guide tube to the other winder for winding. During the winding process, the steel wire that has been wound on the previous winder can be removed; Step 4: Before the switching mechanism cuts off and switches one end of the front end steel wire in the movable seat, the hydraulic station is controlled to inject hydraulic oil into the oil chamber of the hydraulic accumulator through the pump, so that the hydraulic accumulator is in a stored state; when the front end steel wire in the movable seat is cut off and switched, the hydraulic station is closed, the single-way solenoid valve and the three-position four-way solenoid valve are opened, and the hydraulic accumulator provides access to the hydraulic oil in the first oil chamber of the hydraulic cylinder to achieve rapid movement of the telescopic end of the hydraulic cylinder, while the hydraulic oil in the second oil chamber of the hydraulic cylinder is discharged to the hydraulic station through the three-position four-way solenoid valve. After one of the photoelectric sensors detects the position switch, the hydraulic station is opened and the single-way solenoid valve is closed, so that the hydraulic station injects hydraulic oil into the oil chamber of the hydraulic accumulator again through the pump. Oil makes the hydraulic accumulator in the storage state; when the movable seat is reset, the hydraulic station is closed again, the one-way solenoid valve and the three-position four-way solenoid valve are opened, and the hydraulic accumulator provides the hydraulic oil in the second oil chamber of the hydraulic cylinder for a short time, so as to realize the rapid movement of the telescopic end of the hydraulic cylinder, and the hydraulic oil in the first oil chamber of the hydraulic cylinder is discharged to the hydraulic station through the three-position four-way solenoid valve, and then the movement of the movable seat position is detected by the second photoelectric sensor. This is repeated, and the front-end equipment does not need to be shut down. Under the premise that the front-end steel wire is seamlessly connected and guided to the two winders, the rapid movement of the telescopic end of the hydraulic cylinder is controlled, thereby realizing rapid wire cutting and wire position switching. The steel wire is not easy to jump out of the movable seat, reducing the risk factor.

[0017] In summary, the present invention has at least one of the following beneficial effects: 1. The present invention controls the hollow column to rotate in the opposite direction to the direction in which the wire coil is wound. After the end of the steel wire extends out of the hollow column, it is subjected to the traction force of the subsequent wire drawing device, so that one end of the wire coil passes through the guide frame and the interior of the hollow column in sequence and then extends out of the hollow column. In this way, the wire coil is paid out in sequence. The payout is safe and reliable, and the payout method will not have a significant impact on the internal structure of the steel wire.

[0018] 2. The present invention is provided with two winders, a cutting switching mechanism and two guide tubes. When one of the winders is full of steel wire, the steel wire will be cut by controlling the cutting switching mechanism. At the same time of cutting, one end of the front steel wire will be transported to the other winder, realizing seamless connection of steel wire winding, without the need for the front-end equipment to stop working. After one of the winders is switched to wind the steel wire, the steel wire that has been wound on the other winder can be removed during the winding process, which greatly improves the efficiency of steel wire winding.

[0019] 3. The cutting and switching mechanism of the present invention mainly utilizes the characteristics of the hydraulic accumulator, and is used in conjunction with a hydraulic station and a three-position four-way solenoid valve to achieve rapid extension and contraction of the telescopic end of the hydraulic cylinder, thereby controlling the movable seat to move rapidly left and right along the surface of the fixed seat, quickly cutting the steel wire and switching the position of the steel wire, making it difficult for the steel wire to jump out of the movable seat, thereby reducing the risk factor.

[0026] Example 1 Reference Figures 1-14 The present invention discloses a steel wire drawing processing equipment, including a wire pay-off device 100, a wire drawing machine 200, a heating furnace 300, a rapid cooling pool 400, a lubrication groove 500, and a wire take-up device 600. The wire pay-off device 100 includes a support base 101; a hollow column 102 horizontally rotatably connected to the support base 101; a wire pay-off frame 103 rotatably connected to one end of the hollow column 102 away from the support base 101; a limiter 104 provided at the bottom of the wire pay-off frame 103; a guide frame 105 provided on the outer wall of the rotating column; one end of the steel wire located on the wire pay-off frame 103 passes through the guide frame 105 and the interior of the hollow column 102 in sequence and then extends out of the exterior of the hollow column 102; The wire take-up device 600 includes at least two winders 601 and a cutting switching mechanism 602. The cutting switching mechanism 602 includes a fixed support 6021. A fixed support 6022 is provided on the side wall of the fixed support 6021. The fixed support 6022 has a plurality of cutting through holes 6023. A movable seat 6024 is provided on one side of the fixed support 6022. The movable seat 6024 has a guide through hole 6025. The wire-winding device 600 also includes a guide tube 603 corresponding one-to-one to the winder 601, one end of the guide tube 603 is connected to the cutting through hole 6023, and the other end of the guide tube 603 is located on one side of the winder 601; two cutting through holes 6023 are opened on the fixed seat 6022, and the movable seat 6024 is arranged to be close to the surface of the fixed seat 6022.

[0027] With the above structure, by adjusting the limit member 104 away from the pay-off frame 103, the pay-off frame 103 is supported by the hollow column 102, and the wire roll can be placed on the pay-off frame 103, and then the limit member 104 is controlled to limit the pay-off frame 103, so that the hollow column 102 is controlled to rotate in the opposite direction of the wire roll. At this time, the pay-off frame 103 does not rotate, and the end of the steel wire extending out of the hollow column 102 is subjected to the traction force of the subsequent wire drawing device, so that one end of the wire roll passes through the guide frame 105 and the interior of the hollow column 102 in turn and then extends out of the outside of the hollow column 102, thereby realizing sequential pay-off of the wire roll, and the pay-off is safe and reliable, and this pay-off method will not have a significant impact on the internal structure of the steel wire.

[0028] The front end steel wire passes through the guide hole 6025 in the movable seat 6024, one of the cutting holes 6023 in the fixed seat 6022, and one of the guide tubes 603 to one of the winders 601. Two winders 601 are used for winding. When one of the winders 601 is full of steel wire, the movable seat 6024 of the cutting switching mechanism 602 is controlled to move along the fixed seat 6022. The movable seat 6024 faces the side of the fixed seat 6022 to cut the steel wire. At the same time, one end of the front end steel wire is cut. The guiding through hole 6025 in the movable seat 6024 will move to the side of another cutting through hole 6023 in the fixed seat 6022, and will be transported along the inside of the cutting through hole 6023 and another guide tube 603 to another winder 601, so as to realize seamless connection of steel wire winding, without the need for the front-end equipment to stop working. After switching one of the winders 601 to wind the steel wire, the steel wire that has been wound on the other winder 601 can be removed during the winding process, which greatly improves the efficiency of steel wire winding.

[0029] Example 2 Reference Figure 2-Figure 7Based on the same concept as the above-mentioned embodiment 1, the wire drawing processing equipment also includes a shaft seat 106 fixed on the top of the support seat 101, one end of the hollow column 102 is connected to the inside of the shaft seat 106, and the wire pay-off frame 103 includes a baffle 1031. The end of the hollow column 102 away from the shaft seat 106 is connected to the inside of one side of the baffle 1031 through a bearing 1032, and a plurality of wire pay-off rods 1033 are fixed on the other side of the baffle 1031; one end of the hollow column 102 is connected to the inside of the shaft seat 106 through a bearing 1032, which can be It rotates in the shaft seat 106, and the other end of the hollow column 102 is connected to the retaining frame 1031 through the bearing 1032. When paying out the wire, the hollow column 102 rotates while the retaining frame 1031 does not rotate. The provision of multiple wire-paying rods 1033 facilitates the placement of the wire roll, and the wire roll can be horizontally moved to one side of the retaining frame 1031 by pressing one end of the wire-paying rod 1033. The maximum diameter of the retaining frame 1031 is larger than the diameter of the wire roll, so that the retaining frame 1031 can be placed on the wire roll on the wire-paying rod 1033 to limit one side.

[0030] A through hole 107 is provided on the outer wall of the hollow column 102 near the shaft seat 106, and a guide wheel 108 is connected to one end of the through hole 107 near the shaft seat 106, and a guide block 109 is fixed to the other end of the through hole 107. One end of the steel wire on the pay-off frame 103 passes through the guide block 109, the guide wheel 108 and the interior of the hollow column 102 in sequence; the setting of the guide block 109 and the guide wheel 108 can enable one end of the steel wire passing through the guide frame 105 to be guided to the internal axis of the hollow column 102 through the guide block 109 and the guide wheel 108, and extend from the inside to the outside from one end of the hollow column 102.

[0031] The guide frame 105 includes a first fixing ring 1051 and a second fixing ring 1052 arranged in sequence along the baffle 1031 toward the shaft seat 106. The first fixing ring 1051 is fixed to the outside of the hollow column 102. It should be noted here that in order to guide one end of the steel wire that bypasses the baffle 1031 to the inside of the hollow column 102, the fixing ring and the bracket on the fixing ring are provided with at least one group. In this embodiment, there are two groups, namely the first fixing ring 1051 and the second fixing ring 1052. One side wall of the first fixing ring 1051 is fixed with a first bracket 1053, and one side wall of the second fixing ring 1052 is fixed with a first bracket 1054. There is a second bracket 1054, and a wire-blocking wheel group 1055 is fixed on the first bracket 1053, the second bracket 1054 and the shaft seat 106. One end of the steel wire on the wire-paying frame 103 passes around the blocking frame 1031 and through the wire-blocking wheel group 1055 on the first bracket 1053; the first fixing ring 1051 and the second fixing ring 1052 are arranged in sequence along the blocking frame 1031 toward the shaft seat 106 with decreasing lengths. The setting of the wire-blocking wheel group 1055 is to limit the position of the movement of the steel wire, to ensure that the steel wire passes over the blocking frame 1031 and one end of the steel wire is smoothly guided to the inside of the hollow column 102.

[0032] In this embodiment, although the structures of the wire-blocking wheel group 1055 on the first bracket 1053, the second bracket 1054 and the shaft seat 106 are slightly different, they can be summarized as consisting of a wheel seat 1055a, a vertical guide wheel 1055cc and a horizontal guide wheel 1055bb. The wire-blocking wheel group 1055 includes a wheel seat 1055a, on which two parallel horizontal guide wheels 1055b are rotatably connected. The wheel seat 1055a is also rotatably connected to two parallel vertical guide wheels 1055c, and the horizontal guide wheel 1055b is vertically arranged on one side of the vertical guide wheel 1055c. The wheel seat 1055a is a base for fixing. The setting of the two horizontal guide wheels 1055bb and the two vertical guide wheels 1055cc enables the steel wire located between the two horizontal guide wheels 1055bb and the two vertical guide wheels 1055cc to be smoothly guided from the wire roll to the interior of the hollow column 102. A first counterweight 1010 is fixed to a side wall of the first fixing ring 1051 away from the first bracket 1053, and a second counterweight 1011 is fixed to a side wall of the second fixing ring 1052 away from the second bracket 1054. Because the first bracket 1053 and the second bracket 1054 are both located on one side of the hollow column 102, the arrangement of the first counterweight 1010 and the second counterweight 1011 ensures smooth rotation of the hollow column 102.

[0033] In this embodiment, four pay-off rods 1033 are fixed to the side of the retaining frame 1031 away from the hollow column 102. The limiting member 104 includes a limiting seat 1041 located below the pay-off rod 1033. A telescopic cylinder 1042 is fixed to the top of the limiting seat 1041. A limiting block 1043 is fixed to the telescopic end of the telescopic cylinder 1042. Both sides of the limiting block 1043 are provided with inclined surfaces 1044 located between two adjacent pay-off rods 1033. The two upper pay-off rods 1033 serve as the bearing parts of the wire reel. The two lower pay-off rods 1033 can prevent the retaining frame 1031 from rotating when the limiting block 1043 is located between the two pay-off rods 1033 and the hollow column 102 rotates. The telescopic cylinder 1042 can be an air cylinder or an electric telescopic rod. By controlling the telescopic cylinder 1042 to drive the limiting block 1043 to move up and down, the limiting block 1043 moves upward. The pay-off rod 1033 is restricted, and when the limit block 1043 moves downward, it is convenient to place the wire coil to be paid out on the pay-off rod 1033; wherein, after the limit block 1043 moves downward, the blocking frame 1031 is supported by the hollow column 102, and the wire coil to be paid out enters through one end of the pay-off rod 1033 and moves to one side of the blocking frame 1031, and then the limit block 1043 is controlled to move upward to restrict the pay-off rod 1033, and then the pay-off work is carried out. Among them, the inclined surfaces 1044 on both sides of the limit block 1043 enable the limit block 1043 to stably restrict the two pay-off rods 1033 below, preventing the pay-off rods 1033 from shaking after being restricted again.

[0034] In this embodiment, a drive motor 1012 is further included. The output end fixed sleeve of the drive motor 1012 is provided with a first pulley 1013. The outer fixed sleeve of the hollow column 102 located between the shaft seat 106 and the through hole 107 is provided with a second pulley 1014. A first transmission belt 1015 is connected between the first pulley 1013 and the second pulley 1014. The rotation of the hollow column 102 can be achieved in the above-mentioned manner. Specifically, the drive motor 1012 is started, and the drive motor 1012 drives the hollow column 102 to rotate through the first pulley 1013, the second pulley 1014 and the first transmission belt 1015. It should be noted that the rotation direction of the drive motor 1012 should be determined by the winding method of the wire coil after it is placed on the pay-off rod 1033. For example, if the wire coil itself is wound counterclockwise, then the direction of rotation of the hollow column 102 controlled by the drive motor 1012 should be counterclockwise to achieve effective pay-off of the wire.

[0035] Example 3 Reference Figure 8 FIG14 , based on the same concept as the second embodiment above, shows a wire drawing and processing device that also includes a wire take-up device 600, a first support 604, a second support 605, and a third support 606. One end of two guide tubes 603 is placed on the first support 604, the other end of one guide tube 603 is placed on the second support 605, and the other end of the other guide tube 603 is placed on the third support 606. The arrangement of the first support 604, the second support 605, and the third support 606 ensures the stability of the positions of the two guide tubes 603, ensuring that the steel wire can be smoothly guided to the winder 601.

[0036] In this embodiment, the winder 601 includes a support column 6001, the top of the support column 6001 is rotatably connected to a transmission shaft 6002, the top of the transmission shaft 6002 is fixed with a winding turntable 6003, and a reduction motor 6004 is fixed to one side of the support column 6001. The output end fixed sleeve of the reduction motor 6004 is provided with a first transmission wheel 6005, and the outer fixed sleeve of the transmission shaft 6002 is provided with a second transmission wheel 6006. A second transmission belt 6007 is connected between the first transmission wheel 6005 and the second transmission wheel 6006; by controlling the reduction motor 6004 to work, the reduction motor 6004 will drive the transmission shaft 6002 to rotate through the first transmission wheel 6005, the second transmission wheel 6006 and the second transmission belt 6007, thereby driving the winding turntable 6003 above to rotate, thereby winding the steel wire extending from the guide tube 603.

[0037] Several groups of positioning seats 6003a are provided on the top of the winding turntable 6003. The several groups of positioning seats 6003a are arranged in a circular array with the center of the winding turntable 6003 as the center. The top of the positioning seat 6003a is provided with multiple positioning holes 6003b facing the center of the winding turntable 6003, and the positioning holes 6003b are connected to the positioning pipe fittings; by setting the positioning pipe fittings above the several groups of positioning seats 6003a, the diameter of the wire rope coil after being wrapped can be changed.

[0038] The positioning tube includes a long positioning tube 6003c and a short positioning tube 6003d. The long positioning tube 6003c is inserted into the positioning hole 6003b on the positioning seat 6003a close to the center of the winding turntable 6003, and the short positioning tube 6003d is inserted into the positioning hole 6003b on the positioning seat 6003a away from the center of the winding turntable 6003; the guide tube 603 is composed of an integrally formed straight pipe section 6031 and an inclined pipe section 6032, and the end of the straight pipe section 6031 away from the inclined pipe section 6032 is welded to the fixed support 6021 and connected to the cut-off through hole 6023, and the extension line of the end of the inclined pipe section 6032 away from the straight pipe section 6031 is located between the long positioning tube 6003c and the short positioning tube 6003d. The setting of the inclined tube section 6032 allows the steel wire to extend from the inclined tube section 6032 and be transported between the long positioning tube 6003c and the short positioning tube 6003d. As the steel wire is continuously transported, the winding turntable 6003 is driven to rotate, and the steel wire will be wound between the long positioning tube 6003c and the short positioning tube 6003d to form a steel wire roll.

[0039] In this embodiment, the wire take-up device 600 further includes a hydraulic station 609, a hydraulic accumulator 6010, a three-position four-way solenoid valve 6011 and a hydraulic cylinder 6012. The telescopic end of the hydraulic cylinder 6012 is fixed to a side wall of the movable seat 6024 by a fixing clamp 608. The hydraulic station 609 is connected to a port of the hydraulic accumulator 6010 through a one-way valve 6016. The hydraulic station 609 injects hydraulic oil into the oil chamber of the hydraulic accumulator 6010 through a pump, so that the hydraulic accumulator 6010 is in an energy storage state. The hydraulic station 609 is also connected to a port of the three-position four-way solenoid valve 6011 for To recover the hydraulic oil in the hydraulic cylinder 6012, the other port of the hydraulic accumulator 6010 is connected to the other port of the three-position four-way solenoid valve 6011 through the one-way solenoid valve 6017. When the one-way solenoid valve 6017 is opened, the hydraulic accumulator 6010 can provide the hydraulic oil on the other side of the hydraulic cylinder 6012 in a short time, thereby realizing the rapid movement of the telescopic end of the hydraulic cylinder 6012. The other port of the three-position four-way solenoid valve 6011 is connected to the two ports of the hydraulic cylinder 6012, which is used to inject hydraulic oil into one of the oil chambers on both sides of the inner cavity of the hydraulic cylinder 6012, and discharge hydraulic oil from the other side.

[0040] Hydraulic accumulator 6010 utilizes a bladder-type accumulator. During use, nitrogen is injected into the bladder, compressing it as hydraulic oil is injected. Hydraulic accumulator 6010 can provide additional oil at the moment a large amount of pressurized oil is needed, allowing hydraulic cylinder 6012 to instantly receive a large amount of pressurized oil. This ability to provide high-pressure oil in a short period of time meets the equipment's rapid movement requirements. In conjunction with hydraulic station 609 and three-position, four-way solenoid valve 6011, the telescopic end of hydraulic cylinder 6012 can be rapidly extended and retracted, thereby controlling the rapid left and right movement of movable seat 6024 along the surface of fixed seat 6022. This allows for rapid wire cutting and switching, preventing the wire from jumping out of movable seat 6024 and minimizing risk.

[0041] In this embodiment, a slide 6013 is fixed to the top and bottom of one side of the fixed seat 6022, with a movable seat 6024 slidably connected between the two slides 6013. A mounting block 6014 is fixed to a side wall of the movable seat 6024 away from the fixed seat 6022. An extension sleeve 6015 is fixed to the mounting block 6014 and is connected to a guide hole 6025 in the movable seat 6024. The slides 6013 connected to both sides of the fixed seat 6022 prevent the movable seat 6024 from deviating during rapid movement, thereby achieving a wire cutting effect. The extension sleeve 6015 can restrain the cut end of the front wire, preventing it from jumping out of the extension sleeve 6015 in a short time. After the movable seat 6024 switches position, the cut end of the wire in the extension sleeve 6015 is transported out through the guide hole 6025 in the movable seat 6024.

[0042] A receiving plate 6018 is mounted on the top of the fixed clamp 608, and a mounting plate 6019 is fixed to the side wall of the fixed support 6021. Two photoelectric sensors 607 are mounted on the mounting plate 6019. The photoelectric sensors 607 are electrically connected to the hydraulic station 609, the one-way solenoid valve 6017, and the three-position, four-way solenoid valve 6011. The provision of the photoelectric sensors 607 accurately determines the movement position of the movable seat 6024, ensuring that, after movement, the guide hole 6025 within the movable seat 6024 aligns with the cutting hole 2023 within the fixed seat 6022. After cutting, one end of the wire can be accurately conveyed through the cutting hole 2023 within the fixed seat 6022 for winding. Furthermore, when the photoelectric sensors 607 detect the receiving plate 6018, they control the one-way solenoid valve 6017 through an external controller to activate it.

[0043] Example 4 Based on the same concept as the third embodiment above, a steel wire drawing process is also included, which specifically includes the following steps: Step S1: Control the telescopic cylinder 1042 to drive the limit block 1043 to move downward, and the wire coil to be paid out enters through one end of the pay-off rod 1033 and moves to one side of the blocking frame 1031, and then control the limit block 1043 to move upward to limit the pay-off rod 1033; one end of the wire coil passes through the blocking wheel group 1055 on the first bracket 1053, the blocking wheel group 1055 on the second bracket 1054, the guide block 109 and the guide After the pulley 108, it reaches the interior of the hollow column 102, and then is connected to the wire drawing machine 200, the heating furnace 300, the rapid cooling pool 400, and the lubrication groove 500 in sequence through the wire blocking wheel group 1055 on the shaft seat 106, and the drive motor 1012 is started. The drive motor 1012 drives the hollow column 102 to rotate through the first pulley 1013, the second pulley 1014 and the first transmission belt 1015. The rotation of the hollow column 102 drives the wire coil to pay out the wire; Step S2: After the steel wire extends from the hollow column 102, it enters the multi-pass wire drawing machine 200 for drawing, then enters the heating furnace 300 for heating, enters the rapid cooling pool 400 for cooling, and is oiled in the lubrication tank 500 before being taken up by the take-up device 600; Step S3: The front end steel wire continuously passes through the guide hole 6025 in the movable seat 6024 when the pay-off device 100, the wire drawing machine 200, the heating furnace 300, the rapid cooling pool 400 and the lubrication groove 500 are working without stopping, and then passes through one of the cutting holes 6023 and one of the guide tubes 603 to one of the winders 601. The winder 601 starts the reduction motor 6004 below when the steel wire needs to be wound. The reduction motor 6004 The winding turntable 6003 is driven to rotate by the first transmission wheel 6005, the second transmission wheel 6006, the second transmission belt 6007 and the transmission shaft 6002. The steel wire is extended from the inclined tube section 6032 and transported between the long positioning tube 6003c and the short positioning tube 6003d. As the steel wire is continuously transported, the winding turntable 6003 is driven to rotate, and the steel wire is wound between the long positioning tube 6003c and the short positioning tube 6003d to form a steel wire coil. When the reel 601 is full of steel wire, the cutting switching mechanism 602 is controlled to start another reel 601 at the same time. The cutting switching mechanism 602 drives the movable seat 6024 to move. While the steel wire is being cut, one end of the front steel wire moves inside the movable seat 6024 to the side of another cutting through hole 6023 in the fixed seat 6022. The end is then transported along the inside of the cutting through hole 6023 and another guide tube 603 to another reel 601 for reeling. During the reeling process, the steel wire that has been reeled on the previous reel 601 can be removed. Step S4: Before the switching mechanism 602 cuts off and switches one end of the front end steel wire in the movable seat 6024, the hydraulic station 609 is controlled to inject hydraulic oil into the oil chamber of the hydraulic accumulator 6010 through the pump, so that the hydraulic accumulator 6010 is in a stored state; when the front end steel wire in the movable seat 6024 is cut off and switched, the hydraulic station 609 is closed, the one-way solenoid valve 6017 and the three-position four-way solenoid valve 6011 are opened, and the hydraulic accumulator 6010 provides access to the hydraulic oil in the first oil chamber of the hydraulic cylinder 6012 to achieve rapid movement of the telescopic end of the hydraulic cylinder 6012, while the hydraulic oil in the second oil chamber of the hydraulic cylinder 6012 is discharged to the hydraulic station 609 through the three-position four-way solenoid valve 6011. After one of the photoelectric sensors 607 detects the position switch, the hydraulic station 609 is opened and the one-way solenoid valve 6017 is closed, so that the hydraulic station 609 injects hydraulic oil into the oil chamber of the hydraulic accumulator 6010 again through the pump. Hydraulic oil is injected into the oil chamber, so that the hydraulic accumulator 6010 is in an energy storage state; when the movable seat 6024 is reset, the hydraulic station 609 is closed again, the one-way solenoid valve 6017 is opened and the three-position four-way solenoid valve 6011 is switched, and the hydraulic accumulator 6010 provides the hydraulic oil in the second oil chamber of the hydraulic cylinder 6012 for a short time, thereby realizing the rapid movement of the telescopic end of the hydraulic cylinder 6012, and the hydraulic oil in the first oil chamber of the hydraulic cylinder 6012 is discharged to the hydraulic station 609 through the three-position four-way solenoid valve 6011, and then the movement of the position of the movable seat 6024 is detected by the second photoelectric sensor 607. This is repeated, and the front-end equipment does not need to be shut down. Under the premise that the front-end steel wire is seamlessly connected and guided to the two winders 601, the rapid movement of the telescopic end of the hydraulic cylinder 6012 is controlled, thereby realizing rapid steel wire cutting and steel wire position switching. The steel wire is not easy to jump out of the movable seat 6024, thereby reducing the risk factor.

[0044] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
