Description

Technical Field

[0001] The present invention relates to the field related to tire bead galvanizing technology, and in particular to an anti-oxidation treatment device and a treatment process for tire bead steel wire. Background Art

[0002] Steel is prone to oxidation in the air or in a humid environment, forming iron oxides, which is the common rust. Through anti-oxidation treatment, a protective layer with good corrosion resistance can be formed on the surface of the steel wire, preventing oxygen and moisture from corroding the steel surface, thereby extending the service life of the steel wire. Hot-dip galvanizing is a common anti-oxidation treatment method. By plating a layer of zinc on the surface of the steel wire to form an alloy layer of zinc and iron, it effectively prevents oxidation and corrosion of the steel wire.

[0003] Traditional tire bead wire galvanizing equipment has the following shortcomings: when traditional galvanizing equipment galvanizes raw materials, before each raw material enters and exits the zinc liquid, depending on the size of the zinc pool containing the zinc liquid, multiple workers are required to hold a tool with a scraper fixed at the end to scrape the impurities deposited on the surface of the zinc liquid to both sides. This not only places high demands on the workers' skills, but also due to the high temperature of the zinc liquid, the process of scraping away impurities will pose a certain threat to the workers' life safety, and there are potential safety hazards. In order to ensure the safety of the workers each time the impurities are scraped, the raw materials need to be lifted and lowered as slowly as possible, or even stopped, and the overall galvanizing speed of the raw materials will be affected. The speed at which the raw materials are coated with the zinc layer will also be affected by the speed at which the workers scrape away impurities, and the overall work efficiency is not controllable.

DETAILED DESCRIPTION

[0042] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0043] A tire bead wire anti-oxidation treatment process comprises the following steps:

[0044] S1: Pretreatment, degreasing, cleaning and pickling the bead wire to ensure that the surface of the bead wire is clean and free of impurities;

[0045] S2: hot-dip galvanizing, immersing the bead wire treated in step S1 into a preheated molten zinc solution for a period of time to ensure that a uniform galvanized layer is formed on the surface of the bead wire;

[0046] S3: Cleaning: Use a scraper or other tools to clean the bead wire after being treated in steps S1 and S2, and remove oxides, impurities, scum and other substances in the zinc liquid on the surface of the bead wire to ensure the quality and uniformity of the coating;

[0047] S4: drying, drying the bead wire after being processed in steps S1 to S3 to remove excess liquid on the surface of the bead wire;

[0048] S5: Cooling, cooling the tire bead wire after being processed in steps S1 to S4, so that the overall temperature of the tire bead wire is reduced to room temperature.

[0049] refer to Figures 1 to 13 The tire bead wire anti-oxidation treatment device shown in the figure implements the above-mentioned treatment process, comprising:

[0050] A galvanizing pool 1, in which molten zinc and a bracket 3 for supporting a tire bead wire 2 are arranged;

[0051] A gantry 4 is arranged on the top of the galvanizing pool 1 in a manner capable of being raised and lowered;

[0052] A hanger 5 is arranged on the gantry 4 and is used to hang a plurality of tire bead wires 2;

[0053] The scraping and slag removal assembly 6 arranged on the galvanizing pool 1 and the gantry 4 includes two lifting baffles 7 that can be lifted and lowered vertically in a horizontal state on the top of the galvanizing pool 1, two scrapers 8 symmetrically slidably arranged on the two lifting baffles 7 in the horizontal direction, and a reciprocating motion mechanism, wherein the reciprocating motion mechanism includes two sets of driving members symmetrically arranged on both sides of the length direction of the galvanizing pool 1;

[0054] Among them, a number of tire bead wires 2 are arranged at equal intervals along the length direction of the galvanizing pool 1, two lifting baffles 7 and two scrapers 8 are symmetrically arranged on both sides of the length direction and width direction of the galvanizing pool 1, and the driving member includes two elastic telescopic cylinders 9 which are symmetrically distributed on both sides of the width direction of the galvanizing pool 1 and are hingedly connected to the gantry 4 at the opposite ends, the opposite ends of the two elastic telescopic cylinders 9 are respectively connected to the two scrapers 8, and the corresponding ends of each elastic telescopic cylinder 9 are vertically slidably connected to the first optical axis 10 fixedly connected to the corresponding scraper 8.

[0055] The anti-oxidation treatment equipment is applied in step S2, which is used to automatically put a plurality of arranged bead wires 2 into and out of the galvanizing pool 1, and can automatically clean the oxides and impurities accumulated on the surface of the zinc liquid before putting in and out. The gantry 4 is in a raised state before the bead wires 2 are hot-dip galvanized, and a plurality of bead wires 2 are erected on the hanger 5 and located above the galvanizing pool 1. The elastic telescopic cylinder 9 is extended to the longest length, and the ends of the two elastic telescopic cylinders 9 connected to the two scrapers 8 are close to the shortest distance, so that the two scrapers 8 are close to each other and close to each other, and the lifting baffle 7 is also in a raised state on the galvanizing pool 1, so that the bottoms of the two lifting baffles 7 and the scraper 8 are both raised above the zinc liquid surface, and then the gantry 4 is ready to descend, and the lifting baffle 7 falls first before the gantry 4 descends, so that the bottoms of the two lifting baffles 7 and the scraper 8 are slightly immersed below the zinc liquid surface, and then the gantry 4 descends;

[0056] The descent of the gantry 4 is divided into three stages. In the first stage, the gantry 4 is descended for a distance, so that the bottoms of several bead wires 2 on the hanger 5 are close to the surface of the zinc liquid. During this process, the elastic telescopic cylinder 9 will not shrink under its own elastic force, and the two scrapers 8 are moved away from each other. At the end of the first stage, the two scrapers 8 are moved away from the two ends of the two lifting baffles 7, and the two scrapers 8 are hard against the two ends of the two lifting baffles 7 and cannot move away from each other. The ends of the two elastic telescopic cylinders 9 on each side that are hinged to each other on the gantry 4 are still above the ends of the two elastic telescopic cylinders 9 that are moved away from each other.

[0057] The bottoms of the two scrapers 8 have been immersed in the zinc liquid before the first stage, so in the first stage of the descent of the gantry 4, the process of the two scrapers 8 moving away from each other will push the impurities accumulated on the surface of the zinc liquid to both sides, thereby ensuring that the bead wire 2 will not be attached to the impurities when it falls into the zinc liquid in the subsequent process, and after the first stage is completed, the two lifting baffles 7 will rise, and the bottoms of the two lifting baffles 7 and the two scrapers 8 will rise above the zinc liquid;

[0058] Then comes the second stage of the descent of the gantry 4. In the second stage, the gantry 4 continues to descend for a distance, so that several bead wires 2 are completely immersed in the zinc liquid, and at the end of the second stage, the bottoms of several bead wires 2 are close to the bracket 3 but keep a certain distance from the bracket 3. The end of the second stage means that the hot-dip galvanizing process of the bead wires 2 officially begins. Several bead wires 2 are completely immersed in the zinc liquid and wait for the outer surface of the bead wires 2 to be completely coated with a zinc layer. During the descent of the gantry 4 in the second stage, since the two scrapers 8 and the two lifting baffles 7 are hard against each other at the end of the first stage and cannot move away from each other, and the ends of the two elastic telescopic cylinders 9 on each side that are hinged to each other on the gantry 4 are still above the ends of the two elastic telescopic cylinders 9 that are away from each other, the descent of the gantry 4 will drive the two elastic telescopic cylinders 9 to overcome their own elastic force and shrink until the elastic telescopic cylinders 9 shrink to the shortest distance and are horizontal at the end of the second stage;

[0059] The third stage comes next. Between the second stage and the third stage, the gantry 4 will be fixed for a period of time without rising or falling, to ensure that the part of the bead wire 2 exposed to the zinc liquid is completely coated with the zinc layer. In the third stage, the gantry 4 will be lowered for a distance again, so that several bead wires 2 are completely in contact and placed on the bracket 3, and after the bead wire 2 is completely placed on the bracket 3, the hanger 5 will still be driven by the gantry 4 to drop a distance, so that the hanger 5 is separated from the bead wire 2, so that the part of the hanger 5 in contact with the bead wire 2 is exposed to the zinc liquid, to ensure that the part of the bead wire 2 is also completely coated with the zinc layer. After the third stage, the gantry 4 will stay for a period of time again to wait for the bead wire 2 to be completely galvanized. In the third stage, as the gantry 4 descends, one end of the two elastic telescopic tubes 9 on each side that are hinged to each other on the gantry 4 moves to the bottom of the ends of the two elastic telescopic tubes 9 that are away from each other, but because the two scrapers 8 are still in hard contact with the two ends of the two lifting baffles 7 and cannot move away from each other, the elastic telescopic tubes 9 will slowly stretch to the longest length under their own elastic force. After the elastic telescopic tubes 9 are stretched to the longest length, as the gantry 4 continues to descend, the elastic telescopic tubes 9 cannot continue to stretch, so the two ends of the elastic telescopic tubes 9 that are away from each other will approach each other, thereby driving the two scrapers 8 to approach each other, until the end of the third stage, the two scrapers 8 are close to each other again.

[0060] After the three stages of the descent of the gantry 4 are completely completed and the surface of the tire bead wire 2 is completely plated with zinc, the gantry 4 begins to rise. During the rising process, the working principle of the gantry 4 and the two scrapers 8 is consistent with the above-mentioned descent process and will not be described in detail. Before the gantry 4 rises, the lifting baffle 7 drops in advance to drive the bottom of the two scrapers 8 to immerse in the zinc liquid. The initial rise of the gantry 4 corresponds to the first stage of the descent of the gantry 4 mentioned above. The two scrapers 8 move away from each other and push the impurities accumulated on the surface of the zinc liquid to both sides again to prevent the subsequent tire bead wire 2 from contacting the impurities when it rises. After the initial rise of the gantry 4, the two elastic The telescopic cylinder 9 contracts to a horizontal state again, and the two subsequent lifting baffles 7 automatically rise to drive the two scrapers 8 to leave the zinc liquid. The gantry 4 continues to rise, which corresponds to the second stage of the descent of the gantry 4. Initially, it is a process of extension of the two elastic telescopic cylinders 9, which also corresponds to the process of the tire bead wire 2 being driven to rise and leave the zinc liquid. Thereafter, the gantry 4 continues to rise, which corresponds to the first stage of the descent of the gantry 4. Several tire bead wires 2 are lifted back to the initial position to wait for recovery, and the two scrapers 8 are driven to a state of being close to each other, waiting for the next batch of tire bead wires 2 to be galvanized for scraping and slag removal operations.

[0061] In order to connect the galvanizing pool 1, the two lifting baffles 7 and the scraper 8, the following features are specifically set:

[0062] The opposite ends of the two lifting baffles 7 are fixedly connected with a first bracket 11, and two groups of lifting parts corresponding to the two lifting baffles 7 are fixedly arranged on the top of the galvanizing pool 1, each group of lifting parts includes a plurality of electric push rods 12 arranged at equal intervals along the length direction of the galvanizing pool 1, and the output shaft of each electric push rod 12 is vertically upward and fixedly connected to the first bracket 11. Two groups of first limit members corresponding to the two scrapers 8 are fixedly arranged on the side of each lifting baffle 7 close to the corresponding first bracket 11, and each group of the first limit members includes two first slide rails 13 arranged parallel to each other and spaced apart, and a first slider 14 is slidably arranged on each first slide rail 13, the opposite ends of the two scrapers 8 are fixedly connected with a second bracket 15, and each second bracket 15 is fixedly connected with two connecting long plates 16, and the two ends of the two connecting long plates 16 are fixedly connected to a first frame 17 after passing through the two first brackets 11, and the first frame 17 is fixedly connected to the corresponding two first sliders 14, and the first optical axis 10 is fixedly arranged on the first frame 17.

[0063] The cooperation of the two first sliders 14 and the two first slide rails 13 can limit the two scrapers 8, ensuring that the scrapers 8 can only slide in the horizontal direction on the lifting baffle 7. Several electric push rods 12 are used to drive the two lifting baffles 7 and the two scrapers 8 to rise and fall vertically, so that the bottoms of the two lifting baffles 7 and the scrapers 8 can fall into or rise out of the zinc liquid. The first bracket 11 is provided with gaps for avoiding the corresponding four first slide rails 13.

[0064] In order to connect the scraper 8 and the elastic telescopic cylinder 9, the following features are specifically set:

[0065] Two groups of second limit members corresponding to the two groups of driving members are fixedly arranged on the side walls on both sides of the length direction of the galvanizing pool 1, each group of second limit members includes two groups of slide rail members corresponding to the two elastic telescopic cylinders 9, each group of the slide rail members includes two second slide rails 18 arranged in parallel and spaced apart from each other, and each second slide rail 18 is slidably provided with a second slider 19, and the two second sliders 19 in each group of slide rail members are fixedly connected with a second frame 20, each of the first optical axes 10 is slidably provided on the second frame 20 along the vertical direction, and the second frame 20 is also axially provided with a second optical axis 21, and the corresponding end of the elastic telescopic cylinder 9 is fixedly connected to the second optical axis 21.

[0066] Since the lifting baffle 7, the first bracket 11 and the first frame 17 need to be lifted and lowered on the galvanizing pool 1, the scraper 8 and the first frame 17 need to be driven to move horizontally through the second frame 20 and the elastic telescopic cylinder 9. Therefore, the first optical axis 10 is fixedly set on the first frame 17, and the first optical axis 10 is slidably set on the second frame 20 along the vertical direction. In this way, when the two elastic telescopic cylinders 9 drive the two second frames 20 to move horizontally, the two first frames 17 can be driven to move synchronously, and the lifting and lowering of the lifting baffle 7 and the first bracket 11 will not be affected.

[0067] In order to connect the second optical axis 21, the elastic telescopic cylinder 9 and the gantry 4, the following features are specifically provided:

[0068] The elastic telescopic cylinder 9 includes an inner cylinder 22 fixedly connected to the second optical axis 21, an outer cylinder 23 coaxially slidably sleeved on the inner cylinder 22, and a spring 24 coaxially arranged in the outer cylinder 23. The lower end of the gantry 4 is provided with two third optical axes 25 corresponding to two groups of driving parts respectively, and the facing ends of the two outer cylinders 23 in each group of driving parts are hingedly arranged on the third optical axis 25.

[0069] An embedded protrusion 26 for limiting the outer cylinder 23 is fixedly arranged inside the end of the inner cylinder 22 close to the outer cylinder 23, and an inner groove (not shown in the figure) for the embedded protrusion 26 to slide is provided on the inner wall of the end of the outer cylinder 23 away from the inner cylinder 22, so as to ensure that the inner cylinder 22 and the outer cylinder 23 cannot continue to extend after being telescoped to the maximum length. The spring 24 is used to provide sufficient elastic force between the inner cylinder 22 and the outer cylinder 23 to ensure that when the elastic telescopic cylinder 9 is at the maximum length, the two scrapers 8 can still be driven closer or farther away as the gantry 4 is raised and lowered.

[0070] In order to further limit the approach of the two scrapers 8, the following features are specifically set:

[0071] A limiting mechanism is also provided on the first bracket 11, which includes a middle vertical axis 27 fixedly connected to the first bracket 11, a connecting chassis 28 axially sleeved on the middle vertical axis 27, a winding drum 29 fixedly connected to the connecting chassis 28, a coil spring 30 connecting the middle vertical axis 27 and the connecting chassis 28, and two sections of steel rope 31 wound on the winding drum 29, one end of the two sections of steel rope 31 is fixedly connected to the winding drum 29, and the two first frames 17 on each first bracket 11 are fixedly connected with hanging rings 32, and the other ends of the two sections of steel rope 31 are respectively fixedly connected to the two hanging rings 32 after winding out of the steel rope 31.

[0072] In the process of the two scrapers 8 moving away from each other, the two scrapers 8 will pull the two sections of steel rope 31 out of the winding drum 29, thereby driving the winding drum 29 to rotate and causing the coil spring 30 to reel in and accumulate elastic force. The elastic force of the spring 24 in the elastic telescopic tube 9 is large enough to support the elastic telescopic tube 9 from shrinking, so that the coil spring 30 can assist in retracting the two scrapers 8 later. At the same time, a gear (not shown in the figure) and two racks symmetrical about the gear (not shown in the figure) can be added to the first bracket 11. The gear can be axially connected to the first bracket 11, and the two racks can be respectively fixed to the two first frames 17 on the corresponding sides, and then the two racks are meshed with the gear, so as to ensure that the two scrapers 8 always move synchronously and equidistantly.

[0073] In order to hang a plurality of bead wires 2 through the hanger 5, the following features are specifically provided:

[0074] The hanger 5 includes two symmetrically arranged longitudinal hanging plates 33 connected to the gantry 4 and three long thin vertical plates 34 arranged at equal intervals along the width direction of the galvanizing pool 1. The three long thin vertical plates 34 are fixedly arranged at the bottom of the two longitudinal hanging plates 33. The length direction of the long thin vertical plates 34 is parallel to the length direction of the galvanizing pool 1, and each long thin vertical plate 34 is provided with a plurality of supporting slots 35 distributed at equal intervals and used for hanging a plurality of tire bead wires 2. The two scrapers 8 are integrally formed with a bending portion 36 for avoiding the two longitudinal hanging plates 33.

[0075] The longitudinal hanging plates 33 and the long thin vertical plates 34 are both thin plate structures. The three long thin vertical plates 34 are fixed at the positions at the bottom of the two longitudinal hanging plates 33. In this way, a number of supporting slots 35 adapted to the structure of the bead wire 2 are correspondingly opened according to the positions where the bead wire 2 is hung on the three long thin vertical plates 34, so that the bead wire 2 can be kept relatively stably hung on the three long thin vertical plates 34. When the hanger 5 cooperates with the gantry 4 to put a number of bead wires 2 into the zinc liquid in the galvanizing pool 1, in order to ensure that the number of bead wires 2 are subsequently lifted, the two long thin vertical plates 34 need to be kept immersed in the zinc liquid at all times. Before the number of bead wires 2 are subsequently lifted up out of the zinc liquid, the two scrapers 8 need to approach and scrape off the impurities on the surface of the zinc liquid to both sides again. Therefore, two bending portions 36 are integrally formed on the two scrapers 8, so as to avoid the two longitudinal hanging plates 33 when the two scrapers 8 are close to each other.

[0076] In order to receive a plurality of bead wires 2 through the bracket 3, the following features are specifically provided:

[0077] A plurality of equally spaced long supporting blocks 37 for receiving a plurality of tire bead wires 2 are fixedly disposed on the top of the bracket 3 , and a receiving slot 38 for receiving a corresponding tire bead wire 2 is provided on the top of each of the long supporting blocks 37 .

[0078] The top groove edges of the receiving grooves 38 are chamfered to ensure that a plurality of bead wires 2 can fall into the receiving grooves 38 after they fall.

[0079] Working principle: The anti-oxidation treatment equipment is applied in step S2, which is used to automatically put a number of arranged bead wires 2 into and out of the galvanizing pool 1, and can automatically clean the oxides and impurities accumulated on the surface of the zinc liquid before putting in and taking out. The gantry 4 is in a raised state before the bead wires 2 are hot-dip galvanized, and a number of bead wires 2 are erected on the hanger 5 and located above the galvanizing pool 1. The elastic telescopic cylinder 9 is extended to the longest length, and the ends of the two elastic telescopic cylinders 9 connected to the two scrapers 8 are close to the shortest distance, so that the two scrapers 8 are close to each other and close to each other, and the lifting baffle 7 is also in a raised state on the galvanizing pool 1, so that the bottoms of the two lifting baffles 7 and the scraper 8 are both raised above the zinc liquid surface, and then the gantry 4 is ready to descend, and the lifting baffle 7 falls first before the gantry 4 descends, so that the bottoms of the two lifting baffles 7 and the scraper 8 are slightly immersed below the zinc liquid surface, and then the gantry 4 descends;

[0080] The descent of the gantry 4 is divided into three stages. In the first stage, the gantry 4 is descended for a distance, so that the bottoms of several bead wires 2 on the hanger 5 are close to the surface of the zinc liquid. During this process, the elastic telescopic cylinder 9 will not shrink under its own elastic force, and the two scrapers 8 are moved away from each other. At the end of the first stage, the two scrapers 8 are moved away from the two ends of the two lifting baffles 7, and the two scrapers 8 are hard against the two ends of the two lifting baffles 7 and cannot move away from each other. The ends of the two elastic telescopic cylinders 9 on each side that are hinged to each other on the gantry 4 are still above the ends of the two elastic telescopic cylinders 9 that are moved away from each other.

[0081] The bottoms of the two scrapers 8 have been immersed in the zinc liquid before the first stage, so in the first stage of the descent of the gantry 4, the process of the two scrapers 8 moving away from each other will push the impurities accumulated on the surface of the zinc liquid to both sides, thereby ensuring that the bead wire 2 will not be attached to the impurities when it falls into the zinc liquid in the subsequent process, and after the first stage is completed, the two lifting baffles 7 will rise, and the bottoms of the two lifting baffles 7 and the two scrapers 8 will rise above the zinc liquid;

[0082] Then comes the second stage of the descent of the gantry 4. In the second stage, the gantry 4 continues to descend for a distance, so that several bead wires 2 are completely immersed in the zinc liquid, and at the end of the second stage, the bottoms of several bead wires 2 are close to the bracket 3 but keep a certain distance from the bracket 3. The end of the second stage means that the hot-dip galvanizing process of the bead wires 2 officially begins. Several bead wires 2 are completely immersed in the zinc liquid and wait for the outer surface of the bead wires 2 to be completely coated with a zinc layer. During the descent of the gantry 4 in the second stage, since the two scrapers 8 and the two lifting baffles 7 are hard against each other at the end of the first stage and cannot move away from each other, and the ends of the two elastic telescopic cylinders 9 on each side that are hinged to each other on the gantry 4 are still above the ends of the two elastic telescopic cylinders 9 that are away from each other, the descent of the gantry 4 will drive the two elastic telescopic cylinders 9 to overcome their own elastic force and shrink until the elastic telescopic cylinders 9 shrink to the shortest distance and are horizontal at the end of the second stage;

[0083] The third stage comes next. Between the second stage and the third stage, the gantry 4 will be fixed for a period of time without rising or falling, to ensure that the part of the bead wire 2 exposed to the zinc liquid is completely coated with the zinc layer. In the third stage, the gantry 4 will be lowered for a distance again, so that several bead wires 2 are completely in contact and placed on the bracket 3, and after the bead wire 2 is completely placed on the bracket 3, the hanger 5 will still be driven by the gantry 4 to drop a distance, so that the hanger 5 is separated from the bead wire 2, so that the part of the hanger 5 in contact with the bead wire 2 is exposed to the zinc liquid, to ensure that the part of the bead wire 2 is also completely coated with the zinc layer. After the third stage, the gantry 4 will stay for a period of time again to wait for the bead wire 2 to be completely galvanized. In the third stage, as the gantry 4 descends, one end of the two elastic telescopic tubes 9 on each side that are hinged to each other on the gantry 4 moves to the bottom of the ends of the two elastic telescopic tubes 9 that are away from each other, but because the two scrapers 8 are still in hard contact with the two ends of the two lifting baffles 7 and cannot move away from each other, the elastic telescopic tubes 9 will slowly stretch to the longest length under their own elastic force. After the elastic telescopic tubes 9 are stretched to the longest length, as the gantry 4 continues to descend, the elastic telescopic tubes 9 cannot continue to stretch, so the two ends of the elastic telescopic tubes 9 that are away from each other will approach each other, thereby driving the two scrapers 8 to approach each other, until the end of the third stage, the two scrapers 8 are close to each other again.

[0084] After the three stages of the descent of the gantry 4 are completely completed and the surface of the tire bead wire 2 is completely plated with zinc, the gantry 4 begins to rise. During the rising process, the working principle of the gantry 4 and the two scrapers 8 is consistent with the above-mentioned descent process and will not be described in detail. Before the gantry 4 rises, the lifting baffle 7 drops in advance to drive the bottom of the two scrapers 8 to immerse in the zinc liquid. The initial rise of the gantry 4 corresponds to the first stage of the descent of the gantry 4 mentioned above. The two scrapers 8 move away from each other and push the impurities accumulated on the surface of the zinc liquid to both sides again to prevent the subsequent tire bead wire 2 from contacting the impurities when it rises. After the initial rise of the gantry 4, the two elastic The telescopic cylinder 9 contracts to a horizontal state again, and the two subsequent lifting baffles 7 automatically rise to drive the two scrapers 8 to leave the zinc liquid. The gantry 4 continues to rise, which corresponds to the second stage of the descent of the gantry 4. Initially, it is a process of extension of the two elastic telescopic cylinders 9, which also corresponds to the process of the tire bead wire 2 being driven to rise and leave the zinc liquid. Thereafter, the gantry 4 continues to rise, which corresponds to the first stage of the descent of the gantry 4. Several tire bead wires 2 are lifted back to the initial position to wait for recovery, and the two scrapers 8 are driven to a state of being close to each other, waiting for the next batch of tire bead wires 2 to be galvanized for scraping and slag removal operations.
