The uncoiling machine and the shearing machine are adjacently arranged in the first horizontal direction and are arranged on one side, in the second horizontal direction, of the feeding unit, so that the shearing machine moves forwards in the direction close to the roll welding unit in the first horizontal direction, and therefore enough space can be vacated in a working area occupied by the roll welding equipment to place the uncoiling machine; therefore, the occupied space of the roll welding equipment can be saved, the situation that the unwinder interferes with the bearing column or is arranged in the area where other production equipment is located is avoided, and then the situation that the unwinder affects production in other areas can be avoided.

Description

Technical Field

[0001] The present application relates to the technical field of construction pipe pile production, and in particular to a roll welding device. Background Art

[0002] Prestressed concrete pipe piles are widely used in the foundation construction of various buildings due to their high single-pile bearing capacity and convenient construction. Their reinforcement is usually prefabricated into a cage-like shape, known as cage reinforcement. The cage reinforcement primarily consists of several circumferentially evenly distributed main bars (i.e., PC steel rods) and spiral ring reinforcement welded to the outer periphery of the main bars. The welding between the several main bars and the spiral ring reinforcement is currently mainly performed by a roll welder. Prior to roll welding, the roll welder uses an unwinder to release the coiled main bars. A shearing machine then cuts the released main bars into multiple pieces. A reinforcement threading machine then threads the multiple main bars through the wires to form a prefabricated cage reinforcement component.

[0003] Because rolled main bars, ring bars, or welded cage bars often weigh several tons, a crane is installed within the seam welding production site to lift these heavy objects along a track. To ensure crane safety and prevent the track from collapsing, load-bearing columns are typically installed every few meters along the first and second horizontal directions within the seam welding production site. These columns divide the seam welding production site into multiple areas, each housing different production equipment used in different cage bar production processes. Due to the limited travel of the crane, the roll welding machine needs to be set between two adjacent load-bearing columns so that the crane's hoist can reach the location of the roll welding machine to lift the welded cage reinforcement, or lift the cage reinforcement prefabricated parts to the roll welding machine; however, since the uncoiler and the main reinforcement wrapped around itself are usually more than three meters apart, if an uncoiler, shearing machine and reinforcement threading machine are to be set in the roll welding equipment to have the functions of uncoiling, cutting the main reinforcement and threading the reinforcement, the roll welding equipment will occupy more floor space, causing the uncoiler to easily interfere with the load-bearing columns, or be arranged in the area where other production equipment is located, thereby affecting production in other areas. Utility Model Content

The first gear group can rotate around its own central axis in a controllable manner and drive the second gear group to rotate synchronously around its own central axis, so that the traction vehicle can pull the cage reinforcement preform to move along the first horizontal direction.

[0015] In one embodiment, a plurality of lifting devices connected in series along the first horizontal direction are provided at the bottom of the traction track, each of the lifting devices includes a limiting mechanism, a scissor arm and a lifting plate, the lifting plate is arranged on the scissor arm, the scissor arm is used to drive the lifting plate to rise and fall in the vertical direction, and the limiting mechanism is used to abut against the scissor arm so that the lifting plate can be fixed at different height positions.

[0040] This application provides a roll welding production line for manufacturing the steel reinforcement portion (i.e., cage reinforcement) of prestressed concrete piles. The structure of the roll welding production line is described below. This embodiment serves only as an example and does not limit the technical scope of this application. It is understood that in other embodiments, the roll welding production line of this application is not limited to manufacturing cage reinforcement for piles and can also be used to manufacture other products composed of multiple rods, without limitation here.

[0041] The following describes the structure of the automatic rebar threading device in the present application, using an example of an automatic rebar threading device used to thread rebar into a rebar threading plate to ultimately form a rebar cage. It is understood that in other embodiments, the automatic rebar threading device in the present application is not limited to threading rebar into a rebar threading plate to form a rebar cage, but can also grip and transport any rod-shaped workpiece to complete the threading process, without limitation herein.

[0042] See Figure 1 and Figure 2 , Figure 1 and Figure 2 A schematic diagram of a roll welding device in an embodiment of the present application is shown. The roll welding device provided by the present application includes an uncoiler 100, a shearing machine 200, a loading unit 300, a rib-threading unit 400, a roll welding unit 500 and a traction unit 600, wherein the rib-threading unit 400 and the traction unit 600 are arranged on opposite sides of the roll welding unit 500 along a first horizontal direction (the X direction shown in the figure), the loading unit 300 is arranged upstream of the rib-threading unit 400 in a second horizontal direction (the Y direction shown in the figure) perpendicular to the first horizontal direction, the shearing machine 200 is arranged upstream of the loading unit 300 in the second horizontal direction, and the uncoiler 100 and the shearing machine 200 are arranged adjacent to each other in the first horizontal direction. The uncoiler 100 is used to release the main reinforcement wrapped around itself, the shearing machine 200 is used to straighten the released main reinforcement and cut it into multiple bars, the loading unit 300 is used to transport the multiple main reinforcements to the reinforcement threading unit 400 in sequence; the reinforcement threading unit 400 is used to thread the multiple main reinforcements into the roll welding unit 500 to form a cage-shaped cage reinforcement preform; the traction unit 600 is used to pull the cage reinforcement preform to move along the first horizontal direction; the roll welding unit 500 includes a roll welding machine, which is used to spirally wind the annular reinforcement wrapped around a material tray and weld it to the cage reinforcement preform when the traction unit 600 pulls the cage reinforcement preform to move, so as to finally form the cage reinforcement.

[0043] As described in the background, because rolled main bars, ring bars, or welded cage bars typically weigh several tons, a crane is required within the seam welding production site to travel along a track in the air to lift the heavy objects. To ensure crane safety and prevent the track from collapsing, load-bearing columns 20 are typically installed at intervals of several meters along a first horizontal direction and a second horizontal direction within the seam welding production site. These load-bearing columns 20 divide the seam welding production site into multiple areas, each of which houses different production equipment used in different cage bar production processes. Due to the limited travel of the crane, the seam welder needs to be arranged between two adjacent load-bearing columns 20 so that the crane's hoist can reach the location of the seam welder to lift the welded cage reinforcement, or lift the cage reinforcement prefabricated part to the seam welder; however, since the uncoiler 100 and the main reinforcement wrapped around itself are usually greater than three meters, if an uncoiler 100, a shearing machine 200 and a reinforcement threading machine are to be arranged in the seam welding equipment to have the functions of uncoiling, cutting the main reinforcement and threading the reinforcement, the seam welding equipment will take up more floor space, causing the uncoiler 100 to easily interfere with the load-bearing columns 20, or be arranged in the area where other production equipment is located, thereby affecting production in other areas.

[0044] To solve this problem, Figure 2 As shown, in a preferred embodiment, the shearing machine 200 and the loading unit 300 are staggered in the second horizontal direction, so that the uncoiler 100 is also located on one side of the loading unit 300 in the second horizontal direction. In the embodiment shown in the figure, one of the two opposite end faces of the uncoiler 100 along its own axial direction is placed flat on the ground, and the other end face is facing above the rolling welding production line 10 (that is, the central axis of the uncoiler 100 extends in a direction perpendicular to the paper in the figure).

[0045] It can be seen that through the above arrangement, the shearing machine 200 moves forward along the first horizontal direction toward the direction close to the roll welding unit 500, so that sufficient space can be freed up in the working area occupied by the roll welding production line 10 to place the uncoiler 100, avoiding the uncoiler 100 from interfering with the load-bearing column 20 or arranging the uncoiler 100 in the area where other production equipment is located.

[0046] It should be noted that the placement direction of the uncoiler 100 is not limited to the placement direction shown in the embodiment of the figure, that is, the central axis of the uncoiler 100 is not limited to extending in the direction perpendicular to the paper surface, but can also extend along the second horizontal direction, and the uncoiler 100 can also be located on the side of the loading unit 300 along the second horizontal direction, staggered with the shearing machine 200 in the first horizontal direction, and connected with the shearing machine 200 using a curve. There is no limitation here, as long as it is ensured that the uncoiler 100 will not be arranged in the area where other production equipment is located.

[0047] Furthermore, the specific structures of the feeding unit 300 , the reinforcement threading unit 400 , the seam welding unit 500 and the pulling unit 600 are introduced below.

[0048] See Figure 3 , Figure 3 for Figure 1 A magnified schematic diagram of the middle A area, combined with Figures 1 to 3 It can be seen that the loading unit 300 includes a first conveying device 310 and a second conveying device 320. The second conveying device 320 and the first conveying device 310 are arranged upstream of the reinforcement unit 400 in sequence along the second horizontal direction, that is, the second conveying device 320 is arranged upstream of the reinforcement unit 400 along the second horizontal direction, and the second conveying device 320 is arranged upstream of the first conveying device 310 along the second horizontal direction, and the first conveying device 310 is respectively provided with a first heading machine 700 and a second heading machine 800 at both ends of the first horizontal direction, and the first heading machine 700 and the second heading machine 800 are staggered in the first horizontal direction; the first conveying device 310 is used to convey the main reinforcement to move along the first horizontal direction or the second horizontal direction, so that the opposite ends of the main reinforcement are respectively headed by the first heading machine 700 and the second heading machine 800 and then moved to the second conveying device 320, and the second conveying device 320 is used to convey the main reinforcement after heading to the reinforcement unit 400.

[0049] Specifically, in one embodiment, the first conveying device 310 includes multiple groups of intermediate transfer frames 311 spaced apart along the second horizontal direction. The intermediate transfer frames 311 have a V-shaped cross-section. The first heading machine 700 is located at one end of one group of intermediate transfer frames 311, and the second heading machine 800 is located at the end of the other group of intermediate transfer frames 311 away from the first heading machine 700. Each of the aforementioned groups of intermediate transfer frames 311 and the aforementioned other group of intermediate transfer frames 311 is provided with at least one pair of pinching wheels 312, which are used to convey the main bars along the first horizontal direction. A second shifting assembly 313 is provided between each adjacent group of intermediate transfer frames 311, which is used to shift the main bars along the second horizontal direction. The second conveying device 320 is a structure comprising multiple sprockets and chains spaced apart along the first horizontal direction. Each chain has a plurality of limiting slots, so that when all chains are conveyed synchronously, multiple main bars can be conveyed simultaneously along the second horizontal direction to one end near the reinforcing unit 400.

[0050] See Figure 4 and Figure 5 The rib-piercing unit 400 includes two buffer racks 410 spaced apart in the second horizontal direction. Two rib-piercing devices 430 are respectively provided above the two buffer racks 410. Each rib-piercing device 430 can be respectively arranged along the first horizontal direction, the second horizontal direction and the vertical direction ( Figure 1 In the Z direction, Figure 2The rib-piercing device 430 moves in a direction perpendicular to the paper surface so that each rib-piercing device 430 can penetrate the main rib on the corresponding cache rack 410 onto the seam welding unit 500.

[0051] In one embodiment, the seam welding unit 500 further includes a rib-piercing die 520, which is provided with a plurality of rib-piercing holes 520a spaced apart around an axis extending in a first horizontal direction. One of the rib-piercing devices 430 can penetrate the main ribs on one of the buffer racks 410 through some of the rib-piercing holes 520a (e.g., Figure 5 Similarly, another rib-piercing device 430 can also move along the first horizontal direction, the second horizontal direction and the vertical direction respectively to penetrate the main ribs on another cache rack 410 into the remaining rib-piercing holes 520a (for example Figure 5 The remaining half of the reinforcement hole 520a is located on the right side.

[0052] In this way, through the above-mentioned setting, each rib threading device 430 only needs to thread the main ribs on the corresponding cache rack 410 into some rib threading holes 520a of the rolling welding unit 500, so that each rib threading device 430 does not need to move a large distance to thread all the main ribs into all the rib threading holes 520a. Therefore, the rib threading efficiency can be improved, which is faster than manual rib threading. Compared with the traditional rib threading using a single rib threading device 430, the rib threading speed is more than doubled. At the same time, it can also avoid the rib threading device 430 from interfering with the main ribs that have been inserted into the rib threading holes 520a, resulting in rib threading failure.

[0053] Furthermore, if Figure 6As shown, the two rib-piercing devices 430 are staggered in the second horizontal direction, and the two rib-piercing devices 430 have the same structure. In an optional embodiment, the rib-piercing device 430 has a rib-piercing assembly 431 between its head end and tail end, and the rib-piercing assembly 431 includes at least one set of rib-piercing wheel groups, each set of rib-piercing wheel groups includes two rib-piercing wheels set at intervals, one of which is an active rib-piercing wheel and the other is a driven rib-piercing wheel, so that the rib-piercing assembly 431 is at a distance from the head end of the rib-piercing device 430, and when the two rib-piercing devices 430 are offset from each other in the second horizontal direction, ... When the distance is very close, due to the long length of the main bar, the part of the main bar that has been inserted and exposed in the bar hole 520a will sag, causing the parts of the two adjacent main bars exposed in the bar hole 520a to have a larger distance. The reinforcing wheel will not interfere with the parts of the two adjacent steel bars exposed in the bar hole 520a, so that the two reinforcing bar devices 430 can respectively grab two main bars from the two buffer racks 410 and successfully insert the two main bars into the two bar holes 520a with a close distance at the same time. Therefore, the reinforcing rhythm can be well controlled to avoid reinforcing failure due to interference between the reinforcing wheel and the reinforcing bar that has been inserted. Of course, in other embodiments, the number of buffer racks 410 and reinforcing bar devices 430 is not limited to two, and can also be more.

[0054] Preferably, please continue to see Figure 5 The two rib-piercing devices 430 also include a guide assembly 432, wherein the guide assembly 432 is located at the head end of the rib-piercing device 430, and the guide assembly 432 includes at least one set of guide wheel groups, each set of guide wheel groups includes at least one pair of guide wheels, and the guide assembly 432 is used to play a guiding role at the head end of the rib-piercing device 130, so that the main rib can be aligned with the rib-piercing hole 520a so that the main rib can be smoothly inserted into the rib-piercing hole 520a.

[0055] Furthermore, based on the above embodiments, please refer to Figure 5The rolling welding equipment also includes a third conveying device 900 and a first shifting assembly 1000. The third conveying device 900 is arranged between the two buffer racks 410. The first shifting assembly 1000 is arranged between the second conveying device 320 of the loading unit 300 and the third conveying device 900. When the second conveying device 320 sequentially conveys multiple main bars from one end away from the rib-piercing unit 400 to the other end close to the rib-piercing unit 400, the first shifting assembly 1000 can be used to shift part of the main bars from the second conveying device 320 to one of the buffer racks 410 (i.e., a buffer rack 410 close to the second conveying device 320, defined as the first buffer rack 411 herein). At this time, the remaining main bars fall onto the third conveying device 900. The third conveying device 900 can convey the remaining main bars that fall onto itself to another buffer rack 410 (i.e., a buffer rack 410 away from the second conveying device 320, defined as the second buffer rack 412 herein). For example, as Figure 4 As shown, the third conveying device 900 includes a plurality of conveying components 910 and an elevator 920 spaced apart along the first horizontal direction. The elevator 920 is arranged at one end of the conveying component 910 close to the first buffer rack 411. The structure of each conveying component 910 is the same as that of the second conveying device 320, and can simultaneously convey multiple main bars along the second horizontal direction to the position where the elevator 920 is located, and then the elevator 920 will lift the main bars to the second buffer rack 412. The structure of the first toggle component 1000 is similar to that of the second toggle component 313, and will not be repeated here. Of course, the structure of the third conveying device 900 and the second toggle component 313 can also be other structures. For example, the first conveying device 310 can only include the conveying component 910, which is not limited here.

[0056] Figure 7 Shown Figure 1 The enlarged schematic diagram of the C area, from Figure 7 It can be seen that the roll welding device 510 includes a faceplate 511 and a roll welding electrode (not shown in the figure) installed on the faceplate 511. The faceplate 511 is coaxially arranged with the reinforcement die 520 and can rotate around its own central axis under the drive of the motor. In addition, the faceplate 511 is provided with a guide frame 512 for guiding the ring reinforcement to be spirally wound on the cage reinforcement preform. When the faceplate 511 rotates around its own central axis, the guide frame 512 can guide the ring reinforcement to be spirally wound on the cage reinforcement preform. At this time, the roll welding electrode can rotate around the central axis of the faceplate 511 together with the faceplate 511, thereby welding the ring reinforcement to the cage reinforcement preform.

[0057] Preferably, the roll welding electrode is movably mounted on the faceplate 511. Specifically, the roll welding electrode can be controlled to rotate relative to the faceplate 511 around another axis extending along the first horizontal direction under the drive of the cylinder, so as to be able to approach or move away from the rib-piercing die 520 in the radial direction of the faceplate 511. In this way, the roll welding electrode can be opened or closed relative to the reinforcement punching die 520. When roll welding begins, the roll welding electrode can be close to the reinforcement punching die 520, that is, closed relative to the reinforcement punching die 520, so that it can be in contact with the cage reinforcement prefabricated part for roll welding; when roll welding is not performed, the roll welding electrode can be away from the reinforcement punching die 520, that is, open relative to the reinforcement punching die 520, so that the reinforcement punching hole 520a can be avoided, and the roll welding electrode is prevented from blocking the reinforcement punching hole 520a, so that all main reinforcements can pass through the reinforcement punching die 520 smoothly, and there is no need to manually pry open the roll welding electrode and manually punch the blocked main reinforcement again; and because the end of the main reinforcement is also thicker after passing through the swaging head, as the roll welding electrode is in an open state relative to the reinforcement punching die 520, it can also avoid the end of the main reinforcement after the swaging head from hitting the roll welding electrode, thereby avoiding damage to the roll welding electrode.

[0058] More preferably, the roll welding electrode is also movably connected to the faceplate 511 through an adjusting screw. By manually adjusting the adjusting screw, the roll welding electrode can be fixed at different radial positions of the faceplate 511, so that cage reinforcement preforms of different diameters can be roll welded, thereby producing cage reinforcements of different specifications.

[0059] See Figure 8 In one embodiment, the rib-piercing mold 520 includes a base 521, a first rib-piercing plate 522, a second rib-piercing plate 523 and a plurality of rib-piercing tubes 524. The first rib-piercing plate 522 and the second rib-piercing plate 523 are respectively fixedly mounted on opposite ends of the base 521 along the first horizontal direction through locking members 525 that can be removed from the base 521. All rib-piercing tubes 524 are spaced around the central axis of the first rib-piercing plate 522 and the second rib-piercing plate 523, and are sequentially penetrated through the first rib-piercing plate 522 and the second rib-piercing plate 523. Each rib-piercing hole 520a penetrates a corresponding rib-piercing tube 524. Furthermore, the rib-threading die 520 also includes a conductive post 526, a conductive disc 527, and a conductive plate 528. The conductive post 526 is coaxially threaded through the first rib-threading disc 522 and the second rib-threading disc 523, respectively. The conductive disc 527 is disposed at one end of the conductive post 526 near the second rib-threading disc 523. The conductive plate 528 is disposed on the conductive post 526 and located between the first rib-threading disc 522 and the second rib-threading disc 523. During roll welding, the roll welding electrode is connected to the positive terminal of the welding machine, and the conductive plate 528 is connected to the negative terminal of the welding machine, so that the roll welding electrode can serve as the positive terminal during welding. The conductive disc 527 is electrically connected to the negative terminal of the welding machine via the conductive post 526 and the conductive plate 528, so that the conductive disc 527 can serve as the negative terminal, thereby forming a conductive circuit and energizing the welding process.

[0060] Thus, by fixing the first and second ribbed discs 522, 523 to opposite ends of the base 521 along the first horizontal direction via locking members 525, compared to the conventional method of fixing the first and second ribbed discs 522, 523 to the outer circumference of the conductive post 526, the first and second ribbed discs 522, 523 can be further prevented from becoming loose from the conductive post 526 and rotating relative to the conductive post 526, thereby avoiding the inconvenience of repeatedly tightening the first and second ribbed discs 522, 523. Furthermore, by positioning the conductive plate 528 between the first and second ribbed discs 522, 523, the conductive plate 528 can be placed as close to the seam welding electrode (i.e., as close to the welding point) as possible. Compared to conventional structures in which the conductive plate 528 is positioned on the first ribbed disc 522, this reduces the current transmission path, thereby saving energy.

[0061] The traction unit 600 includes a traction track 610 and a tractor 620. The tractor 620 is movably mounted on the traction track 610 and is used to traction the prefabricated cage reinforcement member along a first horizontal direction. The traction track 610 is used to guide the tractor 620 so that the tractor 620 does not deviate from the first horizontal direction. In a preferred embodiment, Figure 9 As shown, a tractor 620 is provided with a first drive assembly 621, a first gear set 622, and a second gear set 623. The first drive assembly 621 is transmission-connected to the first gear set 622, and the second gear set 623 is meshed with the first gear set 622. The end of the second gear set 623 is provided with a first rolling wheel 624, which is rollingly connected to the traction track 610. Driven by the first drive assembly 621, the first gear set 622 can controllably rotate about its own central axis, and drive the second gear set 623 to rotate synchronously about its own central axis, so that the tractor 620 can pull the cage reinforcement preform along the first horizontal direction at a stable speed and with a large pulling force. Therefore, compared with the traditional method of pulling the cage reinforcement preform via a chain, the spiral pitch of the ring reinforcement spirally wound on the cage reinforcement preform can be maintained constant, thereby avoiding the use of excessive ring reinforcement due to the difficulty in controlling the spiral pitch of the ring reinforcement, thereby saving raw materials.

[0062] It is worth noting that the national standard has high requirements for the concentricity and flatness of the cage reinforcement. Therefore, as a further improvement to the above embodiment, refer to Figure 1 and Figure 2 , a plurality of lifting devices 630 connected in series along the first horizontal direction are provided at the bottom of the traction track 610, such as Figure 10As shown, each lifting device 630 includes a limiting mechanism 631, a scissor arm 632, and a lifting plate 633. The lifting plate 633 is mounted on the scissor arm 632. The scissor arm 632 is used to drive the lifting plate 633 to rise and fall in the vertical direction. The limiting mechanism 631 is used to abut the scissor arm 632 to enable the lifting plate 633 to be fixed at different heights. Therefore, the cage reinforcement prefabricated member can be supported when the tractor 620 tows the cage reinforcement prefabricated member, preventing the middle portion of the cage reinforcement prefabricated member from sagging, ensuring the flatness and concentricity of the cage reinforcement, and achieving precise positioning of the cage reinforcement prefabricated member in the height direction. Moreover, when the cage reinforcement prefabricated member has different diameters, the height of the lifting plate 633 can be automatically adjusted, thereby accurately ensuring that the central axis of the cage reinforcement prefabricated member with different diameters is at the same height. It also prevents the end face of the produced cage reinforcement from tilting, thereby greatly improving the production quality of the cage reinforcement and meeting the development needs of automated production equipment.

[0063] Finally, combine Figures 1 to 5 , the whole process of cage reinforcement production using the rolling welding production equipment provided by this application is introduced.

[0064] In the first step, the unwinder 100 releases the coiled main reinforcement wrapped around itself;

[0065] In the second step, the shearing machine 200 straightens and shears the released main bars, so that the coiled main bars are cut into multiple pieces;

[0066] In the third step, the first conveying device 310 conveys the cut main bar along the first horizontal direction or the second horizontal direction, so that the opposite ends of the main bar are respectively headed by the first heading machine 700 and the second heading machine 800, and then moved along the second horizontal direction to the second conveying device 320. The second conveying device 320 conveys the headed main bar along the second horizontal direction to the end near the bar threading unit 400;

[0067] In the fourth step, the first shifting assembly 1000 shifts part of the main ribs to the first cache rack 411 , and the remaining main ribs fall onto the third conveying device 900 , which then conveys the remaining main ribs to the second cache rack 412 .

[0068] In the fifth step, the two reinforcement insertion devices 430 respectively insert the main reinforcement on the corresponding buffer rack 410 into the reinforcement insertion hole 520a opened in the reinforcement insertion mold 520 to form a cage reinforcement prefabricated part.

[0069] In the sixth step, the roll welding electrode of the roll welding unit 500 is closed relative to the reinforcement die 520, the faceplate 511 rotates around its own central axis and drives the roll welding unit 500 to rotate around the central axis of the faceplate 511, and at the same time, the tractor 620 of the traction unit 600 pulls the cage reinforcement prefabricated part to move along the first horizontal direction, so that the faceplate 511 can spirally wind the annular reinforcement on the cage reinforcement prefabricated part, and at the same time, the roll welding electrode can weld the annular reinforcement spirally wound on the cage reinforcement prefabricated part to the cage reinforcement prefabricated part; while the tractor 620 pulls the cage reinforcement prefabricated part to move for roll welding, the lifting plates 633 of each lifting device 630 are lifted upward to support the cage reinforcement prefabricated part.

[0070] Finally, after the roll welding is completed, the roll welding electrode is opened relative to the reinforcement die 520, the crane lifts the produced cage reinforcement, and the lifting plate 633 of the lifting device 630 drops back to its original position. The entire roll welding process is completed, and the next cage reinforcement prefabricated part is roll welded again in a cycle.
