Description

Technical Field

[0001] This invention belongs to the field of wire rod welding technology, and in particular to wire rod butt welding machines. Background Technology

[0002] In the production of pipe fittings or wire blanks, in order to obtain a sufficiently long and continuous wire blank, it is often necessary to butt weld the ends of different sections of the wire blank together. During the butt welding operation, welding marks will be left at the welding site. In order to ensure the subsequent use of the wire blank, the welding marks (scars) at the welding site need to be treated.

[0003] Currently, the butt welding of wire rods is mostly carried out in multiple processes, requiring multiple pieces of equipment such as straightening machines, welding machines, grinding machines, feeding equipment, and unloading equipment. A large amount of manual labor is also required, such as grinding, feeding, unloading, and material transfer between processes. This makes the butt welding connection process of wire rods quite complicated, time-consuming, and seriously affects production efficiency. Moreover, the operation involves multiple different processes and different workers, making it difficult to control the quality of the product.

[0004] Therefore, it is necessary to design an integrated device that can automatically weld wire blanks together and clean the weld seams after welding. Summary of the Invention

[0005] To address the problems of cumbersome wire rod butt welding process, inconvenient weld cleaning, and low work efficiency in existing technologies, this invention provides a wire rod butt welding machine. It is designed as a multi-process butt welding machine that can simultaneously complete multiple processes such as wire rod butt welding, scar cleaning, grinding, and blanking, simplifying the process flow and improving production efficiency.

[0006] This invention provides a wire rod butt welding machine. The technical solution to the technical problem includes a horizontal track and a sliding platform slidably connected to the horizontal track. A welding mechanism and a descaling mechanism are fixedly arranged facing each other on the sliding platform. The descaling mechanism includes a stamping component, a grinding component, a sliding frame, and a vertical track. The vertical track is fixed to the sliding platform. The stamping component and the grinding component are fixed to the sliding frame and slidably connected to the vertical track via the sliding frame. The grinding component is located below the stamping component. The stamping component includes an upper left punch, a lower left punch, an upper right punch, and a lower right punch. The head includes a left upper punch, a left lower punch, a right upper punch, and a right lower punch that simultaneously punch and form a circular punching area. The grinding component includes a C-shaped plate, a grinding bracket, friction wheels, and a sanding belt. The grinding bracket is fixedly connected to the C-shaped plate, and the grinding bracket is provided with three circumferentially distributed friction wheels. The sanding belt is installed on the friction wheels. The C-shaped plate can drive the grinding bracket to rotate around the axis of the C-shaped plate. The horizontal movement of the sliding platform and the vertical movement of the sliding frame enable the welding mechanism, the punching component, and the grinding component to move sequentially to the workpiece position for operation.

[0007] In this technical solution, an integrated butt welding machine is designed to centrally process multiple processes such as wire rod butt welding, weld removal, and weld grinding. The butt welding machine is equipped with horizontal and vertical tracks. The welding mechanism can move horizontally, while the stamping and grinding components can move horizontally along the horizontal track together with the welding mechanism, and can also move vertically independently along the vertical guide rail. During the above operations, the position of the wire rod is fixed. Each action is achieved by moving the various working parts on the butt welding machine. Specifically, the horizontal and vertical movements are combined to move each working part to the position of the wire rod for operation. First, the welding mechanism moves to the position of the wire rod and butt welds the ends of the two wire rods together. Since excess solder remains at the weld position after welding, this excess solder generally protrudes from the surface of the wire rod and needs to be aligned. Second, the sliding platform and... The sliding frame moves, causing the stamping component to move to the wire blank position. The four punches of the stamping component simultaneously stamp the excess solder protruding from the wire blank, achieving rough processing of the excess solder. After stamping, most of the excess solder is removed, but a small amount of solder (burrs, flash, etc.) will still remain. Moreover, stamping cannot guarantee the surface smoothness of the weld. Finally, the sliding frame moves upward, causing the grinding component to move to the wire blank position. The wire blank enters the C-shaped plate through the opening, and then the rotation of the C-shaped plate drives the abrasive belt to rotate around the weld position of the wire blank through the grinding bracket. Combined with the rotation of the abrasive belt itself, the circumference of the weld is ground. After grinding is completed, the grinding component moves away from the wire blank through the opening of the C-shaped plate. At this point, the processes of wire blank welding, stamping welding residue, and grinding the weld are completed. This allows multiple processes to be processed centrally on the same equipment, greatly simplifying the wire blank welding process and improving production efficiency. Meanwhile, by performing a process of stamping and then grinding the weld seam, the efficiency and quality of weld seam processing can be guaranteed.

[0008] Preferably, the device further includes an unloading component, which comprises a pulling hook, a pulling cylinder, an unloading track, and an unloading hook. The pulling cylinder is fixed to the upper end of the vertical track, and the pulling hook is fixed to the telescopic rod of the pulling cylinder. One end of the hook faces the area between the welding mechanism and the descraping mechanism. The unloading track is installed horizontally at the upper end of the welding mechanism, and the unloading hook is slidably connected to the unloading track. The range of motion of the unloading track intersects with the range of motion of the hook. The unloading component can hook the workpiece after grinding and, under the action of the pulling cylinder, pull the wire blank away from the working component, allowing the finished wire blank to leave the working area, facilitating the next process and achieving automated unloading.

[0009] Preferably, the welding mechanism includes a welding machine, a first clamping unit, and a second clamping unit. A first straightening component and a second straightening component are provided on both sides of the horizontal track. The straightening centers of the first straightening component and the second straightening component are located on the same straight line. The centers of the first clamping unit and the second clamping unit are collinear and located at the same height as the straightening centers of the first straightening component and the second straightening component. The welding machine is located between the first clamping unit and the second clamping unit. Each of the first clamping unit and the second clamping unit includes a lower positioning mold and an upper positioning mold. One side of the upper positioning mold is rotatably connected to the lower positioning mold. The lower positioning mold and the upper positioning mold cooperate with each other to form a clamping cavity. The first and second straightening components can straighten the two wire blanks that need to be butt-welded. After the welding mechanism moves to the wire blank position, the straightened wire blanks are fixed by the first and second clamping units respectively. After the wire blanks are fixed, the ends of the two wire blanks are butt-welded. The first and second clamping units each include a lower positioning mold, an upper positioning mold, and a structure design in which one side of the upper positioning mold is rotatably connected to the lower positioning mold. In use, the ends of the wire blanks can be clamped by rotation. At the same time, after welding, since the two wire blanks form a whole, the rotatable connection structure can be easily welded into a whole wire blank and released from the clamping unit to avoid interference and facilitate the unloading of the welding mechanism.

[0010] Preferably, the first straightening component and the second straightening component are each provided with a shearing component on the side closest to the welding machine. The shearing component includes a hydraulic actuator and shears, and the shears have a shearing area whose center line is collinear with the straightening center line. The shearing component is provided to remove the ends of the wire blank. Since the ends of the wire blank generally have an oxide layer and parts that cannot be straightened, these parts need to be removed before welding to ensure better welding quality.

[0011] Preferably, the stamping component includes a first clamping assembly, which includes a left clamping unit and a right clamping unit. The left clamping unit includes a lower left fixed plate and an upper left movable plate, and the right clamping unit includes a lower right fixed plate and an upper right movable plate. The upper left punch is mounted on the upper left movable plate, the lower left punch is mounted on the lower left fixed plate, the upper right punch is mounted on the upper right movable plate, and the lower right punch is mounted on the lower right movable plate. The center line connecting the upper left and lower left punches and the center line connecting the upper right and lower right punches form a cross shape. V-shaped guide grooves are provided on the lower left fixed plate, the upper left movable plate, the lower right fixed plate, and the upper right movable plate. The bottom of the V-shaped guide groove has an arc-shaped portion that conforms to the surface of the wire blank. The first clamping assembly ensures a stable fixing effect, making the stamping operation more stable. The four punches arranged in a "+" shape can simultaneously punch from both sides of the scar in pairs when stamping the scar, which can ensure the stability of the wire blank under force during the stamping process and avoid damage to the wire blank. Moreover, the scar removal through the stamping action can greatly improve the scar removal efficiency. The design of the V-shaped guide groove facilitates the positioning of the wire blank.

[0012] Preferably, the stamping component further includes a second clamping assembly. The second clamping assembly includes second clamping units located on both sides of the first clamping assembly. The clamping center lines of the second clamping units are collinear with those of the left and right clamping units. The second clamping unit includes a lower fixed die and an upper movable die. Both the lower fixed die and the upper movable die have arc-shaped grooves. The lower fixed die has lower guide plates at both ends, and the upper movable die has upper guide plates at both ends. Both the upper and lower guide plates have V-shaped guide grooves, and the bottom of the V-shaped guide grooves communicates with the arc-shaped grooves. The second clamping assembly and the first clamping assembly cooperate to achieve four-point positioning and clamping of the wire blank, ensuring a more stable clamping effect. The arc-shaped grooves facilitate the positioning of the wire blank.

[0013] Preferably, the grinding component includes a grinding clamping and fixing component and a grinding drive component. The grinding drive component includes a grinding drive motor, drive wheels, and a synchronous belt. There are four drive wheels distributed on the outer side of the C-shaped piece. The wheel surfaces of the four drive wheels abut against the outer wall of the C-shaped piece, forming a limiting position on the C-shaped piece. The output end of the grinding drive motor is connected to one of the drive wheels. The multiple drive wheels are connected by a synchronous belt. The outer wall of the C-shaped piece is covered with a rubber layer. The grinding clamping and fixing component is used to clamp the wire blank to be ground. The clamping and fixing component includes two grinding clamping units distributed on both sides of the grinding component. The rotation of the C-shaped piece is achieved through friction with the drive wheels, realizing stepless rotation of the C-shaped piece. This allows for adaptive grinding according to different weld conditions of the wire blank. For example, the C-shaped piece can rotate different numbers of revolutions to achieve different degrees of grinding. It also facilitates the repositioning of the C-shaped piece, improving continuous operation capability and efficiency.

[0014] Preferably, the grinding and clamping unit includes a lower fixed mold and an upper movable mold. Both the lower fixed mold and the upper movable mold have arc-shaped grooves. The lower fixed mold has lower guide plates at both ends, and the upper movable mold has upper guide plates at both ends. Both the upper and lower guide plates have V-shaped guide grooves, and the bottom of the V-shaped guide grooves communicates with the arc-shaped grooves. The interlocking structure of the lower fixed mold and the upper movable mold facilitates the entry of the wire blank into the fixed position, and the arc-shaped groove design facilitates the positioning of the wire blank and ensures a better fixing effect.

[0015] Preferably, the central angle corresponding to the opening of the C-shaped piece is 40-60°. The opening of the C-shaped piece should not be too large, as this will cause instability in the movement of the C-shaped piece, while an opening that is too small will make it inconvenient for the wire blank to enter.

[0016] Preferably, the upper left punch, lower left punch, upper right punch, and lower right punch all have a 90° fan-shaped cross-section, and their inner surfaces are arc-shaped, conforming to the surface of the wire blank. The four punches together form a ring-shaped stamping area, maximizing the removal of scars in a single pass. The arc-shaped inner surfaces allow the punches to better conform to the wire blank surface, improving the quality of scar removal.

[0017] In summary, the technical solution of this invention has at least the following beneficial effects:

[0018] 1. The welding machine of this technical solution can simultaneously complete multiple processes such as welding of wire blanks, stamping and cleaning of scars, grinding, and blanking, which simplifies the process flow and improves production efficiency.

[0019] 2. With four synchronously stamping punches, circumferentially protruding scars at the wire blank welding area can be removed in one go, improving the scar treatment efficiency.

[0020] 3. The cross-shaped distribution of the four stamping heads can ensure stability during the stamping process, ensure force balance, and reduce the vibration and deformation of the wire blank.

[0021] 4. The C-shaped design allows the abrasive belt to rotate around the weld position of the wire blank, achieving all-round cleaning of excess solder in the circumferential direction of the weld.

[0022] 5. The rotation of the C-shaped plate is driven by friction, realizing stepless transmission, which can better meet the cleaning needs of different wire blanks;

[0023] 6. During the operation, the wire blank does not need to be transferred, avoiding the time and effort wasted and the risk of damage caused by transferring the wire blank between processes;

[0024] 7. It has enabled automated weld cleaning, which has improved production efficiency and product quality. Attached Figure Description

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] This invention provides a wire rod butt welding machine, which can centrally process wire rod butt welding, weld stamping and descaling, and weld grinding operations. See attached drawing. Figure 1-12 It includes a horizontal track 1 and a sliding platform 2 slidably connected to the horizontal track 1. A welding mechanism 3 and a descaling mechanism are fixed on the sliding platform 2, arranged facing each other. It can be seen that the welding mechanism 3 and the descaling mechanism are a single unit and can slide horizontally along the horizontal track 1 as a whole. The descaling mechanism includes a stamping component 4, a grinding component 5, a sliding frame 6, and a vertical track 7. The vertical track 7 is fixed to the sliding platform 2. The stamping component 4 and the grinding component 5 are fixed to the sliding frame 6 and slidably connected to the vertical track 7 via the sliding frame 6. It can be seen that the stamping component 4 and the grinding component 5 are connected as a single unit via the sliding frame 6, and the two can slide up and down along the vertical track 7 as a whole. The grinding component 5 is located below the stamping component 4, and their working areas are located in the same vertical plane. The stamping component 4 includes an upper left punch 41, a lower left punch 42, an upper right punch 43, and a lower right punch 44. The upper left punch 41, lower left punch 42, upper right punch 43, and lower right punch 44 stamp synchronously and form a circular stamping area. The stamping direction of the four punches is along the axis of the wire blank. The grinding component 5 includes a C-shaped plate 51, a grinding bracket 52, friction wheels 53, and a sanding belt 54. The grinding bracket 52 is fixedly connected to the C-shaped plate 51. The grinding bracket 52 is provided with three circumferentially distributed friction wheels 53. The sanding belt 54 is installed on the friction wheels 53. The C-shaped plate 51 can drive the grinding bracket 52 to rotate around the axis of the C-shaped plate 51. The horizontal movement of the sliding platform 2 and the vertical movement of the sliding frame 6 can move the welding mechanism 3, the stamping component 4, and the grinding component 5 to the workpiece position in sequence for operation.

[0045] This invention designs an integrated butt welding machine that can centrally process multiple processes such as wire rod butt welding, weld seam stamping and descaling, and weld seam grinding. The butt welding machine is equipped with a horizontal track 1 and a vertical track 7. The welding mechanism 3 can move horizontally, while the stamping component 4 and grinding component 5 can move horizontally along the horizontal track 1 together with the welding mechanism 3, or they can move vertically along the vertical guide rail individually. During the above operations, the position of the wire rod is fixed. Each action is achieved by moving the various working components on the butt welding machine. Specifically, the horizontal and vertical movements are combined to move each working component to the position of the wire rod for operation. First, the welding mechanism 3 moves to the position of the wire rod and butt welds the ends of the two wire rods together. Since excess solder remains at the weld seam after welding, this excess solder generally protrudes from the surface of the wire rod and needs to be aligned. Second, the sliding platform 2 and the sliding frame 6 move... The stamping component 4 is moved to the wire blank position. The four punches of the stamping component 4 simultaneously stamp the excess solder protruding from the wire blank, achieving rough treatment of the excess solder. After stamping, most of the excess solder is removed, but a small amount of solder (burrs, flash, etc.) will still remain. Moreover, stamping cannot guarantee the surface smoothness of the weld. Finally, the sliding frame 6 moves upward, causing the grinding component 5 to move to the wire blank position. The wire blank enters the C-shaped plate 51 through the opening. Then, the rotation of the C-shaped plate 51 drives the sanding belt 54 to rotate around the weld position of the wire blank through the grinding bracket 52. In conjunction with the rotation of the sanding belt 54 itself, the circumference of the weld is ground. After grinding is completed, the grinding component 5 moves away from the wire blank through the opening of the C-shaped plate 51. At this time, the processes of wire blank welding, stamping welding residue, and grinding weld are completed. Multiple processes are processed in a centralized manner on the same equipment, which greatly simplifies the wire blank welding process and improves production efficiency. Meanwhile, by performing a process of stamping and then grinding the weld seam, the efficiency and quality of weld seam processing can be guaranteed.

[0046] To facilitate cyclic operations, this invention also includes an unloading component. This component removes the finished wire blank from the work area, facilitating the next welding operation. The unloading component includes a pulling hook 81, a pulling cylinder 82, an unloading track 83, and an unloading hook 84. The pulling cylinder 82 is fixed to the upper end of the vertical track 7. The pulling hook 81 is fixed to the telescopic rod of the pulling cylinder 82, with one end of the hook facing the area between the welding mechanism 3 and the descaling mechanism. The unloading track 83 is horizontally mounted on the upper end of the welding mechanism 3. The unloading hook 84 is slidably connected to the unloading track 83, and its range of motion intersects with that of the hook. The unloading component hooks the finished workpiece and, under the action of the pulling cylinder 82, pulls the wire blank away from the work area, facilitating the next process and achieving automated unloading. In actual operation, when unloading is required, the pulling cylinder 82 first drives the pulling hook 81 to extend towards the workpiece, and then the pulling hook 81 hooks the workpiece. Then the pulling cylinder 82 drives the pulling hook 81 to move upward. When the pulling hook 81 moves to the same height as the unloading hook 84, the unloading hook 84 moves horizontally to the position of the pulling hook 81. Then the pulling hook 81 moves slightly downward. At this time, the wire blank will fall onto the unloading hook 84 under the action of gravity. Then the unloading hook 84 slides in the opposite direction and hooks the workpiece over the top of the welding machine to remove the workpiece from the working area, which facilitates the next wire blank feeding and welding operation.

[0047] The welding mechanism 3 of the present invention includes a welding machine, a first clamping unit, and a second clamping unit. A first straightening component 31 and a second straightening component 32 are provided on both sides of the horizontal track 1. The straightening centers of the first straightening component 31 and the second straightening component 32 are located on the same straight line. The centers of the first clamping unit and the second clamping unit are collinear and at the same height as the straightening centers of the first straightening component 31 and the second straightening component 32. The welding machine is located between the first clamping unit and the second clamping unit. Each of the first clamping unit and the second clamping unit includes a lower positioning mold 33 and an upper positioning mold 34. One side of the upper positioning mold 34 is rotatably connected to the lower positioning mold 33. The lower positioning mold 33 and the upper positioning mold 34 cooperate with each other to form a clamping cavity. The first straightening component 31 and the second straightening component 32 can respectively straighten the two wire blanks that need to be butt welded. When the welding mechanism 3 moves to the wire blank position, the straightened wire blanks will be fixed by the first clamping unit and the second clamping unit respectively. After the wire blanks are fixed, the ends of the two wire blanks are butt welded. The first clamping unit and the second clamping unit both include a lower positioning mold 33, an upper positioning mold 34, and a structure design in which one side of the upper positioning mold 34 is rotatably connected to the lower positioning mold 33. In use, the ends of the wire blanks can be clamped by rotation. At the same time, after welding, since the two wire blanks form a whole, the rotatable connection structure can be easily welded into a whole wire blank and released from the clamping unit to avoid interference and facilitate the unloading of the welding mechanism 3.

[0048] To ensure better welding results, a shearing component 35 is provided on the side of the first straightening component 31 and the second straightening component 32 near the welding machine. The shearing component 35 includes a hydraulic actuator and shears, and the shears have a shearing area whose center line is collinear with the straightening center line. The shearing component 35 is provided to remove the ends of the wire blank. Since the ends of the wire blank generally have an oxide layer and parts that cannot be straightened, these parts need to be removed before welding to ensure better welding quality.

[0049] To ensure a stable stamping effect, the stamping component 4 in this application includes a first clamping assembly 45. The first clamping assembly 45 includes a left clamping unit and a right clamping unit. The left clamping unit includes a lower left fixed plate 451 and an upper left movable plate 452. The right clamping unit includes a lower right fixed plate 453 and an upper right movable plate 454. The upper left punch 41 is mounted on the upper left movable plate 452, the lower left punch 42 is mounted on the lower left fixed plate 451, and the upper right punch... The upper right movable plate 454 is mounted on the upper right movable plate 43, and the lower right punch 44 is mounted on the lower right movable plate. The center line connecting the upper left punch 41 and the lower left punch 42 forms a cross shape with the center line connecting the upper right punch 43 and the lower right punch 44. The lower left fixed plate 451, the upper left movable plate 452, the lower right fixed plate 453, and the upper right movable plate 454 are all provided with V-shaped guide grooves 464. The bottom of the V-shaped guide grooves 464 forms an arc-shaped part that conforms to the surface of the wire blank. The first clamping assembly 45 can ensure a stable fixing effect, making the stamping operation more stable. By setting the four punches in a cross shape, when stamping the scar, the four punches are arranged in pairs and stamp synchronously from both sides of the scar. This can ensure the stability of the force on the wire blank during the stamping process, avoid damage to the wire blank, and remove the scar through the stamping action, which can greatly improve the scar removal efficiency. The design of the V-shaped guide grooves 464 facilitates the positioning of the wire blank.

[0050] To better understand the operation of the four punches, please refer to the appendix. Figure 8 ,in Figure 8 Figure I is a schematic diagram of the common cross-section of the punches on both sides. Figures II and III are schematic diagrams of the cross-sectional positions of the punches on one side. It can be seen that A and C are located on the same side, and B and D are located on the other side. The line connecting A and C is perpendicular to the line connecting B and D. During stamping, A and C move to the right, and B and D move to the left, applying opposite forces to the excess solder at the weld position.

[0051] Furthermore, the stamping component 4 also includes a second clamping assembly, which includes second clamping units located on both sides of the first clamping assembly 45. The clamping center lines of the second clamping units are collinear with those of the left and right clamping units. The second clamping unit includes a lower fixed die 461 and an upper movable die 462. Both the lower fixed die 461 and the upper movable die 462 are provided with arc-shaped grooves 463. The lower fixed die 461 has lower guide plates 466 at both ends, and the upper movable die 462 has upper guide plates 465 at both ends. Both the upper guide plates 465 and the lower guide plates 466 are provided with V-shaped guide grooves 464, and the bottom of the V-shaped guide grooves 464 communicates with the arc-shaped grooves 463. The second clamping assembly and the first clamping assembly 45 cooperate with each other to achieve four-point positioning and clamping of the wire blank, ensuring a more stable clamping effect. The arc-shaped grooves 463 facilitate the positioning of the wire blank.

[0052] To achieve better weld cleaning results, the upper left punch 41, lower left punch 42, upper right punch 43, and lower right punch 44 in this application all have a 90° fan-shaped cross-section. The inner surfaces of the upper left punch 41, lower left punch 42, upper right punch 43, and lower right punch 44 are all arc-shaped, conforming to the surface of the wire blank. The four punches together form a ring-shaped stamping area, which maximizes the removal of scars in one go. The arc-shaped inner surfaces allow the punches to better conform to the surface of the wire blank, improving the quality of scar removal.

[0053] One embodiment of the grinding component 5 in this application includes a grinding clamping and fixing component and a grinding drive component. The grinding drive component includes a grinding drive motor, drive wheels 56, and a timing belt. There are four drive wheels 56 distributed on the outer side of the C-shaped piece 51. The wheel surfaces of the four drive wheels 56 abut against the outer wall of the C-shaped piece 51 and form a limiting effect on the C-shaped piece 51. The output end of the grinding drive motor is connected to one of the drive wheels 56. The multiple drive wheels 56 are connected by a timing belt. The outer wall of the C-shaped piece 51 is covered with a rubber layer. The grinding clamping and fixing component is used to clamp the wire blank to be ground. The clamping and fixing component includes two grinding clamping units distributed on both sides of the grinding component 5. The rotation of the C-shaped plate 51 is achieved through friction with the drive wheel 56, realizing stepless rotation of the C-shaped plate 51. This allows for adaptive grinding according to different weld conditions of the wire blank. For example, the C-shaped plate 51 can rotate different numbers of times to achieve different degrees of grinding. It also facilitates the reset of the C-shaped plate 51, improving continuous operation capability and efficiency.

[0054] The grinding and clamping unit includes a lower fixed mold 57 and an upper movable mold 58. Both the lower fixed mold 57 and the upper movable mold 58 have arc-shaped grooves. The lower fixed mold 57 has lower guide plates at both ends, and the upper movable mold 58 has upper guide plates at both ends. Both the upper and lower guide plates have V-shaped guide grooves 510, and the bottom of the V-shaped guide grooves 510 communicates with the arc-shaped grooves. The interlocking structure of the lower fixed mold 57 and the upper movable mold 58 facilitates the entry of the wire blank into the fixed position, and the arc-shaped groove design facilitates the positioning of the wire blank and ensures a better fixing effect.

[0055] To facilitate the entry of the wire rod and ensure the stability of the overall structure, the central angle corresponding to the opening of the C-shaped piece 51 in this application is 40-60°. The opening of the C-shaped piece 51 cannot be too large, as an excessively large opening will lead to instability in the movement of the C-shaped piece 51, while an excessively small opening will make it inconvenient for the wire rod to enter.

[0056] The integrated welding machine structure in this application enables centralized processing of multiple processes such as straightening, clamping and fixing, welding, weld punching and descaling, weld grinding and unloading during wire rod welding, which greatly improves work efficiency. Moreover, the workpiece does not need to be moved during operation. The orderly execution of each process is achieved by moving the working parts, which can effectively ensure product quality.

[0057] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
