Description

Technical Field

[0001] This invention relates to the field of corrugated steel web production technology, and specifically to an anti-deformation device for welding corrugated steel webs. Background Technology

[0002] A corrugated steel web composite beam bridge is a type of bridge structure that combines a concrete top slab and bottom slab with corrugated steel webs. This type of bridge is widely used in modern bridge engineering due to its advantages such as efficient material utilization, reduced self-weight, and simplified construction process. A corrugated steel web composite beam bridge consists of a concrete top and bottom slab and corrugated steel webs. The corrugated steel webs connect the upper and lower concrete slabs, providing bending stiffness and support force. The corrugated steel webs increase the moment of inertia of the cross-section through their special corrugated shape, which can improve shear resistance and overall stability. The corrugated steel webs are relatively long and are generally welded together from multiple shorter corrugated plates. Before welding, the corrugated plates need to be positioned to improve welding accuracy and ensure welding quality.

[0003] Chinese patent document CN219443966U discloses a welding and fixing device for corrugated steel web plates, including a base. The top of the base has two sliding grooves, and the inner walls of the two sliding grooves are connected to a bidirectional lead screw via bearings. A servo motor is installed on one outer wall of the base, and the output shaft of the servo motor is connected to the bidirectional lead screw. A slider is sleeved on the outer wall of the bidirectional lead screw. The top outer wall of the slider has two moving platforms, and the top of each moving platform has a limit groove. Hydraulic cylinders are installed on both sides of the top outer wall of the moving platforms. The piston rods of the hydraulic cylinders are connected to a top plate. A pressing mechanism is installed at the bottom of the top plate. A gantry frame is installed in the middle of the top outer wall of the base, and a welding mechanism is installed on the top inner wall of the gantry frame.

[0004] In use, place the two corrugated steel webs to be welded on the moving platform, insert the protrusions of the corrugated steel webs into the limiting grooves, then control the hydraulic cylinder piston rod to shorten, the top plate to move downwards, and the extrusion mechanism to move downwards to firmly fix the corrugated steel webs on the moving platform. Control the servo motor to drive the bidirectional lead screw to rotate, and the rotation of the bidirectional lead screw will drive the two moving platforms to move relative to each other. The edges of the two corrugated steel webs will slowly come into contact. After the two corrugated steel webs come into contact, the welding mechanism can be controlled to perform welding.

[0005] However, the above-mentioned patent documents still have the following shortcomings: when the hydraulic cylinder piston rod shortens and drives the top plate to move down, the downward movement of the top plate can drive the extrusion mechanism to extrude and fix the corrugated steel web. However, if the extrusion mechanism applies too much extrusion force to the corrugated steel web, it is easy to cause the corrugated steel web to deform, which will affect the welding and use of the corrugated steel web. Summary of the Invention

[0006] This invention provides an anti-deformation device for welding corrugated steel web plates, aiming to solve the problem in related technologies where excessive extrusion force applied to the corrugated steel web plates by the extrusion mechanism easily leads to deformation of the corrugated steel web plates.

[0007] The present invention provides an anti-deformation device for welding corrugated steel web plates, comprising a frame, a conveying mechanism, a material conveying mechanism, a welding mechanism, and welding equipment, and further comprising a positioning mechanism. The positioning mechanism includes a positioning component, which includes a driving component, a guide component, and multiple positioning components. The driving component is a chain conveyor structure, and the multiple positioning components are mounted on the driving component. The driving component can drive the multiple positioning components to move. Each positioning component includes a connecting part, a positioning part, and an elastic part. The connecting part is inserted into a chain plate inside the driving component, and the elastic part is connected between the connecting part and the chain plate inside the driving component. The positioning part is connected to the end of the connecting part that extends out of the driving component. The positioning part is provided with an arc-shaped surface adapted to the corrugated steel web plate. The guide component is connected inside the driving component. When the positioning component moves above the steel web plate, under the guidance of the guide component, the positioning component can move towards the corrugated steel web plate, so that the positioning part extends into the groove on the corrugated steel web plate and is squeezed and positioned thereon.

[0008] Beneficial effects: When welding and positioning corrugated steel webs, the conveying mechanism is activated, and multiple corrugated steel webs are placed on the conveying mechanism in sequence. The conveying mechanism transports the multiple corrugated steel webs, and at the same time, the material conveying mechanism is activated to synchronously transport the two side plates, so that the two side plates and multiple corrugated steel webs move synchronously. Then, the driving component is activated, which drives multiple positioning components to move along a set trajectory. When the positioning component moves to the corrugated steel web, the positioning part extends into the groove on the corrugated steel web. At this time, under the guidance of the guide component, the positioning part moves towards the corrugated steel web, and continues to move towards the corrugated steel web, pressing and positioning the corrugated steel web. At the same time, the arc-shaped surface on the positioning part that matches the groove of the corrugated steel web can prevent the corrugated steel web from deforming after being pressed.

[0009] Preferably, the positioning component further includes a roller, which is installed at one end of the connecting portion that extends into the inner chain plate of the drive component.

[0010] Its effect is that when the positioning component passes the guide component, the roller contacts the guide component, thereby reducing the friction between the positioning component and the guide component.

[0011] Preferably, the guide includes a horizontal segment one, an inclined segment, a horizontal segment two, and two arc-shaped segments. The inclined segment is connected between the horizontal segment one and the horizontal segment two. The two arc-shaped segments are respectively connected to the ends of the horizontal segment one and the horizontal segment two that are far apart from each other. The distance between the horizontal segment one and the driving component is greater than the distance between the horizontal segment two and the driving component.

[0012] The effect is as follows: When roller 1 passes through the arc-shaped section connected to horizontal section 1 and moves onto horizontal section 1, under the guidance of the arc-shaped section and horizontal section 1, roller 1 drives the connecting part to move towards the corrugated steel web and compresses elastic part 1. When the connecting part moves, it drives the positioning part to move so that the positioning part can move towards the corrugated steel web. However, at this time, the arc-shaped surface on the positioning part does not fully contact the groove on the corrugated steel web and the positioning part is in a vertical state. When roller 1 leaves horizontal section 1 and moves to horizontal section 2 through the inclined section, under the action of the inclined section, roller 1 drives the connecting part to continue moving towards the corrugated steel web and continues to compress elastic part 1. When the connecting part moves, it continues to drive the positioning part to move so that the positioning part continues to move towards the corrugated steel web. At the same time, the positioning part squeezes and positions the corrugated steel web until the arc-shaped surface on the positioning part is fully fitted with the groove on the corrugated steel web, thereby achieving the squeezing and positioning of the corrugated steel web.

[0013] Preferably, there are two positioning mechanisms, positioned one in front of the other.

[0014] Its effect is that the two positioning mechanisms can respectively squeeze and position the front and rear ends of the corrugated steel web, thereby enhancing the squeezing and positioning effect of the corrugated steel web.

[0015] Preferably, each positioning mechanism contains two positioning components, which are arranged one above the other, and the corrugated steel web can be located between the two positioning components.

[0016] Its effect is that the two positioning components can compress the corrugated steel web to form a clamping and positioning of the corrugated steel web, thereby enhancing the positioning effect of the corrugated steel web.

[0017] Preferably, the positioning mechanism further includes auxiliary components, and multiple auxiliary components are provided, with the multiple auxiliary components respectively installed on multiple positioning parts.

[0018] Preferably, the interior of the positioning part is hollow, and multiple notches are provided on the arc-shaped surface of the positioning part.

[0019] Preferably, the auxiliary component includes a mounting part, an auxiliary structure, and a pushing structure. The mounting part is connected inside the positioning part, the auxiliary structure is connected to the mounting part, the auxiliary structure can extend from the notch on the arc surface of the positioning part, and assist in pushing two adjacent corrugated steel webs to align. The pushing structure is connected to the positioning part and is used to control the auxiliary structure to extend into or out of the positioning part.

[0020] Its effect is that, through the auxiliary structure, the corrugated steel web can be positioned when the positioning component passes through the arc-shaped section and the horizontal section connected to the guide component.

[0021] Preferably, the pushing structure includes a pushing part, a guiding part, a driving source, and a lead screw. The pushing part is slidably connected inside the positioning part, the guiding part is connected to the pushing part, the guiding part passes through the positioning part and is movably connected to it, the driving source is connected to the side of the positioning part near the driving member, the lead screw is connected to the output shaft of the driving source, the lead screw is located inside the positioning part, and the pushing part is threadedly connected to the lead screw.

[0022] Preferably, the auxiliary structure includes a movable part, a second roller, and a second elastic part. The movable part is inserted into the mounting part, the second elastic part is connected between the movable part and the mounting part, one end of the movable part is in contact with the pushing part, and the second roller is installed at the end of the movable part away from the pushing part.

[0023] The beneficial effects of this invention are:

[0024] When welding corrugated steel webs, multiple corrugated steel webs are sequentially conveyed by a conveying mechanism, while two side plates are conveyed simultaneously by a material conveying mechanism. This ensures that the multiple corrugated steel webs and the two side plates move synchronously. During the movement of the corrugated steel webs, multiple positioning components are driven by a drive component and guided by a guide component. The positioning part within the positioning component presses and positions the corrugated steel web. At this time, the arc-shaped surface on the positioning part can fit into the groove on the corrugated steel web to prevent deformation of the corrugated steel web after being pressed. Simultaneously, the conveying mechanism and multiple positioning components can continuously position the multiple corrugated steel webs, thereby accelerating the welding speed of the multiple corrugated steel webs.

[0034] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0035] like Figures 1 to 7 As shown, the anti-deformation device for welding corrugated steel webs of the present invention includes a frame 1, a conveying mechanism 2, a material conveying mechanism 3, a positioning mechanism 4, a welding mechanism 5, and welding equipment. The conveying mechanism 2 is connected to the frame 1 and can sequentially convey multiple corrugated steel webs. The material conveying mechanism 3 is connected to the frame 1 and can convey two side plates so that the side plates and corrugated steel webs move synchronously to facilitate welding of the corrugated steel webs to the side plates. The positioning mechanism 4 is connected inside the frame 1 and can press and position two adjacent corrugated steel webs to facilitate welding of the corrugated steel webs to the side plates and prevent deformation of the corrugated steel webs. The welding mechanism 5 is connected to the positioning mechanism 4 and can weld the corrugated steel webs to the side plates to facilitate subsequent welding of two adjacent corrugated steel webs. The welding equipment is connected to the frame 1 and can weld and fix two adjacent corrugated steel webs after the corrugated steel webs and side plates are welded (the welding equipment is prior art and is not shown in the figure).

[0036] like Figure 1 and Figure 2 As shown, the conveying mechanism 2 includes a mounting frame, conveying rollers, a conveyor belt, and a motor. The mounting frame is connected inside the frame 1. Two conveying rollers are provided, and the two conveying rollers are respectively connected to the inner ends of the mounting frame. The conveyor belt is connected between the two conveying rollers. The motor is connected to the mounting frame, and the output end of the motor is connected to one of the conveying rollers. Starting the motor can drive the transmission between the conveyor belt and the two conveying rollers. At this time, after multiple corrugated steel webs are placed on the conveyor belt in sequence, the conveyor belt can drive the multiple corrugated steel webs to move to the right. Under the action of the positioning mechanism 4, adjacent two corrugated steel webs are squeezed and positioned so that the corrugated steel webs can be welded to the side plates by the welding mechanism 5. At the same time, it is convenient for the welding equipment to weld adjacent two corrugated steel webs after the corrugated steel webs are welded to the side plates.

[0037] When welding corrugated steel webs, the motor is first started, driving the conveyor belt and two conveyor rollers to begin operation. Multiple corrugated steel webs are then placed sequentially on the conveyor belt, while two side plates are placed on the feeding mechanism 3, positioned on the front and rear sides of the webs. The feeding mechanism 3 then conveys the side plates synchronously. Next, the positioning mechanism 4 is activated to sequentially press and position the webs. Then, the welding mechanism 5 is activated to weld the webs to the two side plates. Finally, adjacent webs are welded together. The pressing and positioning by the positioning mechanism 4 prevents deformation. The synchronous conveying of the webs and side plates by the feeding mechanism 2 and feeding mechanism 3 ensures continuous welding, improving welding efficiency.

[0038] like Figure 1 and Figure 2 As shown, the material conveying mechanism 3 includes two conveying components 31 and two limiting components 32. Both the two conveying components 31 and the two limiting components 32 are connected to the frame 1. The two conveying components 31 are located on the front and rear sides of the conveying mechanism 2, respectively. The two conveying components 31 can convey the two side plates respectively. The two conveying components 31 are located between the two limiting components 32, respectively, which can limit the two side plates so that the two side plates can contact the front and rear sides of the multiple corrugated steel webs respectively. This is so that after the multiple corrugated steel webs are positioned by the positioning mechanism 4, the corrugated steel webs and side plates can be welded by the welding mechanism 5. At the same time, the two side plates can limit the corrugated steel webs to prevent the corrugated steel webs from tilting.

[0039] like Figures 1 to 7As shown, two positioning mechanisms 4 are configured. These two positioning mechanisms 4 can respectively press and position the front and rear ends of the corrugated steel web. Each positioning mechanism 4 includes two positioning components. The corrugated steel web is positioned between the two positioning components. The two positioning components can clamp and press the corrugated steel web from above and below, thereby pressing and positioning the corrugated steel web. Each positioning component includes a drive member 41, positioning components 42, auxiliary components 43, and guide components 44. The drive member 41 is a chain conveyor structure with a running chain plate. Five positioning components 42 and five auxiliary components 43 are each configured. The five positioning components 42 are all connected to the chain plate of the drive member 41, and the five auxiliary components 43 are respectively connected to the five positioning components 44. On the positioning member 42, the chain plate inside the driving member 41 can drive five positioning members 42 to move along a set trajectory when running, so that the five positioning members 42 are inserted into the grooves on multiple corrugated steel webs in sequence. The guide member 44 is connected inside the driving member 41. When the positioning member 42 passes the guide member 44, the guide member 44 can guide the positioning member 42 so that the positioning member 42 moves toward the corrugated steel web, thereby pressing and positioning the corrugated steel web to facilitate the subsequent welding and fixing between the corrugated steel web and the side plate. The auxiliary member 43 can assist in pressing the corrugated steel web when the positioning member 42 presses and positions it, so as to reduce the friction between the positioning member 42 and the corrugated steel web.

[0040] When the corrugated steel web is extruded and fixed, the drive unit 41 is activated to make the chain plate inside the drive unit 41 run. The chain plate running inside the drive unit 41 drives the five positioning pieces 42 to move along the set trajectory. When the five positioning pieces 42 move along the set trajectory, they are inserted into the grooves on the corrugated steel web. When the positioning pieces 42 pass the guide piece 44, the guide piece 44 guides the positioning pieces 42 to move towards the corrugated steel web. Through the corresponding positioning pieces 42 on the two positioning components, the corrugated steel web is clamped and extruded, thereby extruding and positioning two adjacent corrugated steel webs. The shape of the positioning piece 42 is adapted to the shape of the corrugated steel web to prevent the corrugated steel web from deforming after being extruded and positioned.

[0041] Continue to refer to Figures 1 to 7As shown, the positioning component 42 includes a connecting part 421, a positioning part 422, an elastic part 423, and a roller 424. The connecting part 421 is inserted into the chain plate inside the drive component 41. The elastic part 423, which is a compression spring, connects the connecting part 421 and the chain plate. The elastic part 423 prevents the connecting part 421 from falling off the chain plate. The positioning part 422 is connected to the side of the connecting part 421 that extends out of the chain plate. When the positioning part 422 moves along a set trajectory, it can be inserted into a groove on the corrugated steel web to achieve compression positioning of the corrugated steel web. The positioning part 422 has an arc-shaped surface. The arc-shaped surface on part 422 is adapted to the groove on the corrugated steel web to prevent the corrugated steel web from deforming after being squeezed by the positioning part 422. The drive member 41 is activated so that the chain plate inside the drive member 41 can drive the connecting part 421, the positioning part 422 and the elastic part 423 to move along the set trajectory. The roller 424 is installed at the end of the connecting part 421 that extends into the chain plate. When the positioning part 42 passes the guide member 44, the roller 424 can contact the guide member 44, thereby reducing the friction between the positioning part 42 and the guide member 44. The guide member 44 is connected to the inside of the drive member 41.

[0042] Continue to refer to Figures 1 to 7As shown, the guide member 44 includes a horizontal section 1, an inclined section, a horizontal section 2, and two arc-shaped sections. The inclined section connects the horizontal section 1 and the horizontal section 2. The two arc-shaped sections are respectively connected to the ends of the horizontal section 1 and the horizontal section 2 that are far apart from each other. The distance between the horizontal section 1 and the driving member 41 is greater than the distance between the horizontal section 2 and the driving member 41. When the roller 424 passes through one of the arc-shaped sections and contacts the horizontal section 1, under the guidance of the arc-shaped section and the horizontal section 1, the roller 424 drives the connecting part 421 to move towards the corrugated steel web and compresses the elastic part 423. When the connecting part 421 moves, it drives the positioning part 422 to move, so that the positioning part 422 can move towards the corrugated steel web. However, at this time, the arc-shaped surface on the positioning part 422 does not fully contact the groove on the corrugated steel web, and the positioning part 422 is in a vertical position. In the straight state, when roller 424 disengages from horizontal section 1 and moves through the inclined section to horizontal section 2, the inclined section causes roller 424 to drive connecting part 421 to continue moving towards the corrugated steel web and to continue compressing elastic part 423. As connecting part 421 moves, it continues to drive positioning part 422 to move, so that positioning part 422 continues to move towards the corrugated steel web. At the same time, positioning part 422 squeezes and positions the corrugated steel web until the arc-shaped surface on positioning part 422 is completely fitted with the groove on the corrugated steel web. When roller 424 disengages from horizontal section 2 and passes through the arc-shaped section connected to horizontal section 2, the elastic part 423 causes connecting part 421 to drive positioning part 422 and roller 424 to gradually return to their original positions until roller 424 completely disengages from the arc-shaped section connected to horizontal section 2.

[0043] When the corrugated steel web is extruded and positioned, the drive unit 41 is activated, which drives the five positioning units 42 to move along the set trajectory. When the roller 424 on the positioning unit 42 passes through the arc segment connected to the horizontal segment, under the action of the arc segment, the roller 424 drives the connecting part 421 to move towards the corrugated steel web and compresses the elastic part 423. When the connecting part 421 moves, it drives the positioning part 422 to extend into the groove on the corrugated steel web. Under the action of the horizontal segment, the positioning part 422 keeps moving in a straight line. At this time, the arc surface on the positioning part 422 is not completely in contact with the groove on the corrugated steel web.

[0044] As the driving component 41 drives the positioning component 42 to continue moving, the roller 424 gradually disengages from the first horizontal section and moves to the second horizontal section after passing through the inclined section. When the roller 424 passes through the inclined section, the guiding action of the inclined section causes the roller 424 to drive the connecting part 421 to continue moving towards the corrugated steel web, and to continue compressing the elastic part 423. As the connecting part 421 moves, it continues to drive the positioning part 422 to move towards the corrugated steel web, whereby the positioning part 422 presses and positions the corrugated steel web until the positioning part 423... The arc-shaped surface on 22 is completely fitted with the groove on the corrugated steel web. After the roller 424 moves to the second horizontal section, the positioning part 422 maintains the state of pressing and positioning the corrugated steel web, and the arc-shaped surface on the positioning part 422 is always completely fitted with the groove on the corrugated steel web. When the roller 424 leaves the second horizontal section and passes through the arc-shaped section connected to the second horizontal section, the connecting part 421 drives the positioning part 422 and the roller 424 to gradually reset under the action of the elastic part 423, until the roller 424 completely leaves the arc-shaped section connected to the second horizontal section.

[0045] Continue to refer to Figures 1 to 7 As shown, the auxiliary component 43 includes a mounting part 431, an auxiliary structure, and a pushing structure. The pushing structure includes a pushing part 435, a guide part 436, a drive source 437, and a lead screw 438. The positioning part 422 is hollow inside, and multiple notches (not shown in the figure) are provided on the arc-shaped surface of the positioning part 422. The mounting part 431 is connected inside the positioning part 422. Multiple auxiliary structures are provided, and each of the multiple auxiliary structures is mounted on the mounting part 431. The multiple auxiliary structures can pass through the multiple notches on the arc-shaped surface of the positioning part 422. Through the auxiliary structures, when the positioning part 422 is inserted into the groove on the corrugated steel web, the corrugated steel web can be pushed, thereby aligning two adjacent corrugated steel webs and reducing the friction on the corrugated steel web. The pushing part 435 is slidably connected inside the positioning part 422, and the guide part 436 is connected to the pushing part 435. The guide part 436 passes through the positioning part 422 and is movably connected to it. The moving direction of the positioning part 422 can be guided by the guide part 436. The driving source 437 is connected to the side of the positioning part 422 near the driving member 41. The driving source 437 is a motor. The lead screw 438 is connected to the output shaft of the driving source 437. The lead screw 438 is located inside the positioning part 422, and the pushing part 435 is threadedly connected to the lead screw 438. When the driving source 437 drives the lead screw 438 to rotate, the pushing part 435 can be driven by the lead screw 438 to move in a direction closer to or away from the driving member 41 under the guidance of the guide part 436.

[0046] When the roller 424 on the positioning member 42 passes through the arc-shaped section connected to the horizontal section 1, under the action of the arc-shaped section, the roller 424 drives the connecting part 421 to move towards the corrugated steel web and compresses the elastic part 423. When the connecting part 421 moves, it drives the positioning part 422 to extend into the groove on the corrugated steel web. At this time, the corrugated steel web is pushed by the auxiliary structure, thereby aligning two adjacent corrugated steel webs. As the roller 424 gradually disengages from the horizontal section 1 and moves to the horizontal section 2 after passing through the inclined section, when the roller 424 passes through the inclined section, under the guiding action of the inclined section, the roller 424 drives the connecting part 421 to continue moving towards the corrugated steel web. The steel web moves in the direction of compression and continues to compress the elastic part 423. When the connecting part 421 moves, it continues to drive the positioning part 422 to move towards the corrugated steel web. The positioning part 422 squeezes and positions the corrugated steel web until the arc surface on the positioning part 422 is completely in contact with the groove on the corrugated steel web. When the positioning part 422 continues to move towards the corrugated steel web, the drive source 437 is activated to drive the lead screw 438 to rotate. Under the guidance of the guide part 436, the lead screw 438 drives the pushing part 435 to move towards the drive member 41 so that the auxiliary structure is taken into the positioning part 422 from the notch on the arc surface of the positioning part 422.

[0047] Continue to refer to Figures 1 to 7 As shown, the auxiliary structure includes a movable part 432, a second roller 433, and a second elastic part 434. The movable part 432 is inserted into the mounting part 431, and the second elastic part 434 is connected between the movable part 432 and the mounting part 431. One end of the movable part 432 is in contact with the pushing part 435, and the second roller 433 is installed at the end of the movable part 432 away from the pushing part 435.

[0048] When the connecting part 421 moves, it drives the positioning part 422 to extend into the groove on the corrugated steel web. At this time, the roller 433 on the auxiliary structure extends out from the notch on the positioning part 422. The roller 433 can push the corrugated steel web to align two adjacent corrugated steel webs and reduce the friction on the corrugated steel web. As the positioning part 422 continues to move towards the corrugated steel web so that the arc surface on the positioning part 422 is completely in contact with the groove on the corrugated steel web, the lead screw 438 drives the pushing part 435 to move towards the driving member 41. At this time, under the action of the elastic part 434, the moving part 432 can drive the roller 433 to gradually retract into the positioning part 422.

[0049] Working principle:

[0050] When welding the corrugated steel web, the motor is started, and the transmission between the motor and the two conveyor rollers is used to start the conveyor belt. Then, multiple corrugated steel webs are placed on the conveyor belt in sequence, and two side plates are placed on the conveying mechanism 3 so that the two side plates are located on the front and rear sides of the multiple corrugated steel webs respectively. The conveying mechanism 3 conveys the two side plates to achieve synchronous conveying of the two side plates and multiple corrugated steel webs.

[0051] Start the drive unit 41 to make the chain plate inside the drive unit 41 run. The chain plate running inside the drive unit 41 drives the five positioning parts 42 to move along the set trajectory. When the roller 424 on the positioning part 42 passes through the arc section connected to the horizontal section, under the action of the arc section, the roller 424 drives the connecting part 421 to move towards the corrugated steel web and compresses the elastic part 423. When the connecting part 421 moves, it drives the positioning part 422 to extend into the groove on the corrugated steel web. At this time, the corrugated steel web is pushed by the auxiliary structure, thereby aligning the two adjacent corrugated steel webs. Under the action of the horizontal section, the positioning part 422 keeps moving in a straight line. At this time, the arc surface on the positioning part 422 is not completely in contact with the groove on the corrugated steel web.

[0052] As the driving component 41 drives the positioning component 42 to continue moving, the roller 424 gradually disengages from the first horizontal section and moves to the second horizontal section after passing through the inclined section. When the roller 424 passes through the inclined section, the guide action of the inclined section causes the roller 424 to drive the connecting part 421 to continue moving towards the corrugated steel web, and to continue compressing the elastic part 423. As the connecting part 421 moves, it continues to drive the positioning part 422 to move towards the corrugated steel web, where the positioning part 422 presses and positions the corrugated steel web until the arc-shaped surface of the positioning part 422 completely fits the groove on the corrugated steel web. At this point, the driving source 437 is activated to drive the lead screw 438 to rotate, and the guide part 424... Under the guidance of 36, the pusher 435 is driven by the lead screw 438 to move toward the drive member 41, so that the auxiliary structure is taken into the positioning part 422 from the notch on the arc surface of the positioning part 422. After the roller 424 moves to the horizontal section 2, the positioning part 422 maintains the state of pressing and positioning the corrugated steel web, and the arc surface on the positioning part 422 is always completely in contact with the groove on the corrugated steel web. When the roller 424 leaves the horizontal section 2 and passes through the arc section connected to the horizontal section 2, the connecting part 421 drives the positioning part 422 and the roller 424 to gradually reset under the action of the elastic part 423, until the roller 424 completely leaves the arc section connected to the horizontal section 2.

[0053] After the corrugated steel web is extruded and positioned, the corrugated steel web is welded to the side plate by the welding mechanism 5, and finally the two adjacent corrugated steel webs are welded by the welding equipment.
