Description

Technical Field

[0001] This application relates to the technical field of electrostatic precipitators, in particular to a manufacturing process and production equipment for the R-S wire of an electrostatic precipitator. Background Art

[0002] As one of the commonly used cathode wires in electrostatic precipitators, the R-S wire has various structural forms, which can generally be divided into two categories: integral group welding and split group welding. Integral group welding is to punch two half pieces on the same sheet of metal and obtain them through forming and welding. This method has a low material utilization rate. Split group welding is to separately manufacture the spike teeth, tube blanks, and connecting pipes and then perform group welding.

[0003] Chinese Patent Application Publication No. CN101862958A discloses a special machine for automatically producing the R-S wire of an electrostatic precipitator. This special machine improves the traditional production process, integrates the production processes, and improves the production efficiency and product quality. However, the spike teeth of the R-S wire produced by it are directly welded to the outer side of the tube blank part. Since the R-S wire is in contact with corrosive gases for a long time in the working environment of the electrostatic precipitator, during use, the welding position between the spike teeth and the tube blank part is easily corroded, resulting in the spike teeth falling off from the tube blank part, thereby reducing the service life of the R-S wire. Summary of the Invention

[0004] The present invention aims to overcome the deficiencies of the prior art and provides a manufacturing process and production equipment for the R-S wire of an electrostatic precipitator. This process and equipment can automatically produce the R-S wire with the spike tooth fixing part coated on the side part of the tube blank part to improve the service life of the R-S wire in a corrosive environment.

[0005] To achieve the above object, this application adopts the following technical solutions: A manufacturing process for the R-S wire of an electrostatic precipitator includes the following steps: Step 100: Use metal parts to process the tube blank semi-blank and spike teeth. The tube blank semi-blank includes a semi-tube part and side parts located on opposite sides of the semi-tube part. The spike teeth include a fixing part and a discharge part with a discharge tip. Step 200: Transport the spike teeth to the corresponding positions on the side part of the first tube blank semi-blank. Step 300: Perform stamping on the spike teeth arranged on the first tube blank semi-blank to bend the discharge tip of the spike teeth, and bend one end of the fixing part of the spike teeth close to the semi-tube part to form a bent part, and the bent part abuts against the inner wall of the semi-tube part. Step 400: After sequentially completing the transportation and stamping of multiple spike teeth, butt the second tube blank semi-blank with the first tube blank semi-blank and weld the side parts of the two to form a tube blank part. The side part of the first tube blank semi-blank and the side part of the second tube blank semi-blank cover the fixing part. Step 500: Use a press head machine to stamp the end of the tube blank part into a flat connecting part.

[0006] The above-mentioned electrostatic precipitator RS line manufacturing process has achieved a dual improvement in product reliability and production efficiency through product structure optimization and integration of manufacturing processes. Its core innovations are: 1) adopting the enclosing structure of the side edges of the double-sided tube blank half-blank, the fixed part of the serration is completely covered between the two side edges, forming a physical isolation barrier, effectively blocking the direct contact between the corrosive medium in the use environment and the fixed part, and can significantly reduce the risk of the serration falling off; 2) the bending part and the inner wall of the half-tube are mechanically interlocked, and this structure can still provide reliable anti-pullout force when the connection between the fixed part and the side edge fails; 3) implementing synchronous collaborative processing in the stamping process, and completing the bending of the discharge tip while forming a mechanical interlocking between the bending part and the inner wall of the half-tube, merging the two processing operations into one operation, which can improve the overall processing efficiency. This can be achieved through the optimization design of the mold structure, reducing the equipment modification cost without affecting the production cycle time; 4) through the process layout optimization, the process of enclosing and welding the tube blank half-blank to form the tube blank, which was originally required to be pre-placed, is integrated into this process, which can reduce the parts processing requirements before this process and reduce the parts processing time and cost.

[0007] Furthermore, in step 200: the awns are welded on the side edge of the first tube half blank.

[0008] By adopting the above-mentioned technical solution, the serrations are first welded to the side edge of the first tube blank half-blank, and then stamping and other operations are performed. This can preliminarily fix the position of the serrations on the tube blank half-blank, facilitate the subsequent accurate stamping of the serrations, bend the discharge tip of the serrations and form a bent portion at the fixed portion, and better control the abutment position and state of the bent portion and the inner wall of the half-tube portion, which is conducive to achieving the expected mechanical interlocking effect.

[0009] Furthermore, in step 300: when the serrations installed on the first tube half-blank are stamped, the position where the serrations are installed on the side portion is stamped simultaneously, so that the position where the serrations are installed on the side portion is concave to form a mounting groove for accommodating the serrations, and the upper surface of the fixing portion is flush with the upper surface of the side portion that is not connected to the serrations.

[0010] Adopting the foregoing technical solution, by means of the step of forming the mounting groove synchronously through barbed stamping, there is no need to add new processes and additional components, avoiding the cost increase caused by the introduction of new components, and at the same time, it will not affect the overall production efficiency. It realizes the completion of multiple process objectives without additional consumption of resources and time. At the same time, the mounting groove enables the fixing part of the barbs to be located within the mounting groove. When the two semi-finished tube blanks are enclosed, it can effectively restrict the movement of the barbs in the length direction of the tube blank, enhancing the stability of the barbs on the tube blank. When the two semi-finished tube blanks are butted, since the upper surface of the fixing part is flush with the upper surface of the side part where the barbs are not connected, the second semi-finished tube blank can be directly and seamlessly butted with the first semi-finished tube blank without any additional processing in the subsequent process. The above technical solution also eliminates the possible structural differences between the two semi-finished tube blanks before entering this process. The two semi-finished tube blanks can be completely replaced with each other, reducing the number of parts and further reducing the production cost. The presence of the mounting groove can effectively restrict the movement of the barbs in the length direction of the tube blank, enhancing the stability of the barbs on the tube blank.

[0011] Further, a step 150 is provided between step 100 and step 200. Step 150: Stamping a plurality of mounting grooves for accommodating barbs on the side part through a stamping device; in step 200, the fixing part of the barbs is placed in the corresponding mounting groove, and the upper surface of the fixing part is flush with the upper surface of the side part where the mounting groove is not formed.

[0012] Adopting the foregoing technical solution, by stamping and forming the mounting groove on the side part in advance, the position, size and shape of the mounting groove can be more accurately controlled, ensuring that each barb can be accurately placed in the corresponding mounting groove, thereby improving the accuracy and consistency of barb installation. This helps to ensure the quality stability of the R-S line and reduce the performance differences caused by the deviation of the barb installation position. Since the mounting groove is stamped and formed in a separate step, it is convenient to inspect and control the quality of the mounting groove in this step, and timely discover and correct possible problems, such as size deviation and irregular shape of the mounting groove, which is beneficial to improving the yield rate of the product.

[0013] Further, in step 100, a plurality of mounting grooves for accommodating barbs are provided on the side part of the processed semi-finished tube blank; in step 200, the fixing part of the barbs is placed in the corresponding mounting groove, and the upper surface of the fixing part is flush with the upper surface of the side part where the mounting groove is not formed.

[0014] Adopting the foregoing technical solution, the installation groove is set during the processing of the tube blank semi-finished part in step 100, integrating the processing of the installation groove into the initial processing link of the tube blank semi-finished part, further simplifying the overall production process. Compared with separately setting subsequent steps to stamp the installation groove, this method makes the entire manufacturing process more compact and coherent, reduces the connection time between processes, and improves production efficiency. Processing the installation groove simultaneously with the processing of the tube blank semi-finished part does not require additional equipment and complex operations to separately stamp the installation groove. This not only reduces the processing difficulty, decreases the equipment investment and labor costs that may be brought about by adding processes, but also reduces the rejection rate caused by operation errors in multiple steps, thereby further reducing the production cost.

[0015] Further, in step 300, when performing stamping forming, make the bending position of at least one of the discharge tips close to the end of the side part away from the semi-tube part, so that the discharge tip and the bent part clamp the side part from opposite sides.

[0016] Adopting the foregoing technical solution, making the bending position of at least one discharge tip close to the end of the side part away from the semi-tube part, and the discharge tip and the bent part clamp the side part from opposite sides, forms a structure similar to "clamping". This structure greatly increases the connection firmness between the barbs and the side part of the tube blank semi-finished part, effectively preventing the barbs from falling off the side part due to external forces during use, and enhancing the stability and reliability of the overall structure of the R-S line. This clamping form is equivalent to providing a redundant design for the connection between the barbs and the tube blank semi-finished part, adding an extra safeguard for the connection between the barbs and the tube blank semi-finished part. Even if there are problems with the welded part, the clamping structure can still play a role, effectively delaying equipment failures caused by the falling off of the barbs, extending the overall service life of the electrostatic precipitator, reducing the frequency of equipment maintenance and replacement, and lowering the maintenance cost.

[0017] An R-S line production device for an electrostatic precipitator, applicable to the above-mentioned R-S line manufacturing process for an electrostatic precipitator, includes a frame, a tube blank transmission line for transmitting tube blank semi-finished parts and tube blank parts, and a feeding device, a loading device, a second welding machine, and a pressing head machine sequentially arranged along the transmission direction of the tube blank transmission line. The tube blank transmission line is installed on the frame; It further includes a forming machine, and the feeding device and the forming machine are arranged on opposite sides of the same processing station of the tube blank transmission line; Or, it further includes a first welding machine and a forming machine. The feeding device and the first welding machine are arranged on opposite sides of the same processing station of the tube blank transmission line, and the forming machine is arranged downstream of the first welding machine and upstream of the loading device.

[0018] Adopting the foregoing technical solutions, the above production equipment can achieve the processing of the new R-S wire. The first welding machine and the second welding machine can be spot welding machines, laser welding machines, or other commonly used welding machines. In the first of the above solutions, the production equipment includes a forming machine. When the tube blank transmission line conveys the first tube blank semi-finished part to the position of the feeding device, the feeding device sequentially sends out a plurality of spike teeth. The forming machine punches and forms the spike teeth placed on the first tube blank semi-finished part, bends the discharge tip of the spike teeth, and bends one end of the fixing part of the spike teeth close to the semi-tube part to form a bent part, and the bent part abuts against the inner wall of the semi-tube part; then the tube blank transmission line conveys the first tube blank semi-finished part to the position where the feeding device is arranged, the feeding device sends out the second tube blank semi-finished part, and docks the second tube blank semi-finished part with the first tube blank semi-finished part. Then the tube blank transmission line conveys the two tube blank semi-finished parts to the position where the second welding machine is arranged, and the second welding machine welds and fixes the second tube blank semi-finished part and the first tube blank semi-finished part to form a tube blank part, and makes the side part of the first tube blank semi-finished part and the side part of the second tube blank semi-finished part wrap and clamp the fixing part; the tube blank transmission line conveys the tube blank part to the position where the pressing head machine is arranged, and then punches and forms the end part of the tube blank part into a flat connecting part through the pressing head machine. The tube blank transmission line continues to convey and sends out the processed R-S wire from the above production equipment. In the second of the above solutions, when the production equipment includes a first welding machine and a forming machine, when the tube blank transmission line conveys the first tube blank semi-finished part to the position of the feeding device, the feeding device sequentially sends out a plurality of spike teeth. The first welding machine sequentially welds the plurality of spike teeth at the corresponding positions on the side part of the first tube blank semi-finished part. The tube blank transmission line conveys the first tube blank semi-finished part to the position where the forming machine is arranged, and the forming machine punches and forms the spike teeth installed on the first tube blank semi-finished part, bends the discharge tip of the spike teeth, and bends one end of the fixing part of the spike teeth close to the semi-tube part to form a bent part, and the bent part abuts against the inner wall of the semi-tube part. During this process, the forming machine can also synchronously punch the position where the spike teeth are installed on the side part, so that the position where the spike teeth are installed on the side part sinks to form an installation groove for accommodating the spike teeth; the tube blank transmission line conveys the tube blank semi-finished part to the position where the feeding device is arranged, the feeding device sends out the second tube blank semi-finished part, and docks the second tube blank semi-finished part with the first tube blank semi-finished part. Then the tube blank transmission line conveys the two tube blank semi-finished parts to the position where the second welding machine is arranged, and the second welding machine welds and fixes the second tube blank semi-finished part and the first tube blank semi-finished part to form a tube blank part, and makes the side part of the first tube blank semi-finished part and the side part of the second tube blank semi-finished part wrap and clamp the fixing part; the tube blank transmission line continues to convey the tube blank semi-finished part to the position where the pressing head machine is arranged, and then punches and forms the end part of the tube blank part into a flat connecting part through the pressing head machine. The tube blank transmission line continues to convey and sends out the processed R-S wire from the above production equipment.

[0019] Preferably, the method further comprises a stamping device, wherein the stamping device is arranged upstream of the feeding device.

[0020] In the above technical solution, the tube blank transmission line transports the first tube blank half blank to the position where the stamping equipment is set, and the stamping equipment punches and forms a number of mounting grooves for accommodating the serrations on the side. Then the tube blank transmission line transports the first tube blank half blank to the position where the feeding device is set, and the feeding device sends multiple serrations to the mounting grooves in sequence.

[0021] Furthermore, the forming machine includes a fixed frame, an upper lifting drive, an upper mold, a lower mold and a lower lifting drive. The upper lifting drive is installed on the fixed frame and drives the upper mold to rise and fall. The lower lifting drive is installed on the fixed frame and drives the lower mold to rise and fall. After the upper mold and the lower mold are closed, they form a forming cavity for accommodating the awn teeth. The upper mold is provided with a first extrusion block for downwardly extruding the bending part and a second extrusion block for downwardly extruding the fixed part and the side part. The lower mold is provided with a concave groove at a position corresponding to the second extrusion block.

[0022] With the aforementioned technical solution, the forming machine controls the lifting and lowering of the upper and lower dies respectively through the upper and lower lifting drives, and can accurately control the speed, pressure, and position of the mold closing. This allows the serrations to be accurately controlled during the stamping process, whether it is the bending angle of the discharge tip or the shape and position of the bent portion formed by the bending of the fixed portion, thereby ensuring the consistency and precision of the serration forming, which is beneficial to improving the overall quality and performance of the RS line. The forming machine in the aforementioned technical solution can, during stamping, stamp the serrations provided on the first tube blank half-blank, so that the discharge tip of the serrations is bent, and the fixed portion of the serrations is bent near one end of the half-tube portion to form a bent portion, the bent portion abutting against the inner wall of the half-tube portion, and can also simultaneously stamp the position where the serrations are installed on the side portion, so that the position where the serrations are installed on the side portion is concave to form a mounting groove for accommodating the serrations.

[0023] Furthermore, the loading device includes a stacking rack, a first pushing mechanism, a second pushing mechanism and a guide frame. A discharge port is provided at the bottom of the stacking rack. The first pushing mechanism is provided at a position corresponding to the discharge port, and is used to push the tube blank half-blank located at the bottom of the stacking rack to the guide frame. The second pushing mechanism is provided at a position corresponding to the guide frame, and is used to push the tube blank half-blank on the guide frame to the loading station. A positioning block is provided on the side of the tube blank transmission line away from the guide frame, and the pushing directions of the first pushing mechanism and the second pushing mechanism are vertical.

[0024] By adopting the above-mentioned technical solution, the stacking rack can store multiple tube blanks and half-blanks, and the first ejection mechanism can push the tube blanks and half-blanks at the bottom of the stacking rack to the guide rack in sequence, thereby realizing automatic loading, reducing manual operations, and improving loading efficiency. The guide rack guides the tube blanks and half-blanks so that they can be accurately pushed to the loading station. At the same time, the positioning block provided on the side of the tube blank transmission line away from the guide rack can accurately position the tube blanks and half-blanks, ensuring their accurate position in subsequent processing, which is conducive to improving processing accuracy and product quality. The pushing directions of the first ejection mechanism and the second ejection mechanism are perpendicular. This design enables the tube blanks and half-blanks to be pushed smoothly in different directions, can better adapt to the transmission direction of the tube blank transmission line and the position requirements of the loading station, and increases the flexibility and adaptability of the loading device.

[0025] Furthermore, the loading device also includes a blanking control mechanism, which includes a fixed block, a moving block, a fixed rack, a sliding rack, a first spring, a second spring and a limit gear, the limit gear is rotatably connected to the stacking rack, and one of the teeth of the limit gear supports the pipe blank half billet located in the stacking rack, the fixed block is fixed to the stacking rack, the fixed rack and the sliding rack are arranged side by side, the fixed rack is fixed to the moving block, the sliding rack is slidably connected to the moving block, and has a first position and a second position, the second spring is arranged between the sliding rack and the moving block to keep the sliding rack in the first position, the moving block is slidably connected to the fixed block, and has a locking position that enables the fixed rack to mesh with the limiting gear and an unlocking position that enables the sliding rack to mesh with the limiting gear, the first spring is arranged between the fixed block and the moving block to keep the moving block in the locked position, when the sliding rack switches from the first position to the second position, the sliding rack moves a distance of a tooth pitch, and when the telescopic rod of the first pushing mechanism is retracted, the telescopic rod presses and causes the moving block to move to the unlocked position.

[0026] Using the aforementioned technical solution, a tooth on the limit gear supports the tube half. A tube half is released only when the sliding rack switches position and meshes with the limit gear. This effectively prevents over-cutting or inaccurate cutting, ensuring accurate and stable loading. The first ejection mechanism's telescopic rod, when retracted, presses against the movable block to unlock it, achieving automatic triggering of cutting. Without the need for additional control systems or manual intervention, the entire loading process is more automated and streamlined, reducing manual workload and the potential for error, thereby improving production efficiency.

[0032] As Figures 12 to 13 shown, an R-S line of an electrostatic precipitator includes two pipe blank semi-blank parts 1.1 and several spike teeth 1.2. The pipe blank semi-blank part 1.1 includes a semi-pipe part 1.1.1 and side parts 1.1.2 located on opposite sides of the semi-pipe part 1.1.1. The two pipe blank semi-blank parts 1.1 are stacked and welded to form a pipe blank part 1.3. The pipe blank part 1.3 includes a pipe blank body 1.3.0, connecting parts 1.3.1 located at both ends of the pipe blank body 1.3.0, and pipe blank side edges 1.3.2 located on opposite sides of the pipe blank body 1.3.0. The pipe blank side edges 1.3.2 are formed by enclosing and welding the side parts 1.1.2 of the two pipe blank semi-blank parts 1.1. Several spike teeth 1.2 are arranged at intervals on the pipe blank side edges 1.3.2. The spike teeth 1.2 include a fixing part 1.2.1 and a discharging part 1.2.2. The side parts 1.1.2 of the two pipe blank semi-blank parts 1.1 cover the fixing part 1.2.1, and the discharging part 1.2.2 is provided with a discharging tip 1.2.3.

[0033] Embodiment 1: As Figure 1 shown, the present application provides a manufacturing process for an R-S line of an electrostatic precipitator, including the following steps: Step 100: Process the pipe blank semi-blank part 1.1 and the spike teeth 1.2 with metal parts. The pipe blank semi-blank part 1.1 includes a semi-pipe part 1.1.1 and side parts 1.1.2 located on opposite sides of the semi-pipe part 1.1.1. The spike teeth 1.2 include a fixing part 1.2.1 and a discharging part 1.2.2 having a discharging tip 1.2.3; Step 200: Transport the spike teeth 1.2 to the corresponding positions on the side parts 1.1.2 of the first pipe blank semi-blank part 1.1; Step 300: Perform stamping on the spike teeth 1.2 arranged on the first pipe blank semi-blank part 1.1 to bend the discharging tip 1.2.3 of the spike teeth 1.2, and bend one end of the fixing part 1.2.1 of the spike teeth 1.2 close to the semi-pipe part 1.1 to form a bent part 1.2.4, and the bent part 1.2.4 abuts against the inner wall of the semi-pipe part 1.1; Step 400: After sequentially completing the transportation and stamping of multiple spike teeth 1.2, dock the second pipe blank semi-blank part 1.1 with the first pipe blank semi-blank part 1.1, and weld the side parts 1.1.2 of the two to form a pipe blank part 1.3. The side parts 1.1.2 of the first pipe blank semi-blank part 1.1 and the side parts 1.1.2 of the second pipe blank semi-blank part 1.1 cover the fixing part 1.2.1; Step 500: The end of the tube blank 1.3 is punched into a flat connecting portion 1.3.1 by a punching machine 6.

[0034] The manufacturing process of the electrostatic precipitator RS line 1 has achieved a dual improvement in product reliability and production efficiency through product structural optimization and integration of manufacturing processes. Its core innovations are: 1) The enclosed structure of the side portions 1.1.2 of the double-sided tube half-blank 1.1 is adopted to completely cover the fixed portion 1.2.1 of the tooth 1.2 between the two side portions 1.1.2, forming a physical isolation barrier, effectively blocking the direct contact between the corrosive medium in the use environment and the fixed portion 1.2.1, which can significantly reduce the risk of the tooth 1.2 falling off; 2) The bending portion 1.2.4 is mechanically interlocked with the inner wall of the half-tube portion 1.1.1. This structure can still provide reliable anti-pullout force when the connection between the fixed portion 1.2.1 and the side portion 1.1.2 fails; 3) In the stamping process, the fixed portion 1.2.1 is completely enclosed between the two side portions 1.1.2, forming a physical isolation barrier, effectively blocking the direct contact between the corrosive medium in the use environment and the fixed portion 1.2.1, and can significantly reduce the risk of the tooth 1.2 falling off; 2) The bent portion 1.2.4 is mechanically interlocked with the inner wall of the half-tube portion 1.1.1. This structure can still provide reliable anti-pullout force when the connection between the fixed portion 1.2.1 and the side portion 1.1.2 fails; 3) In the stamping process, the fixed portion 1.2.1 is completely enclosed between the two side portions 1.1.2, forming a physical isolation barrier, effectively blocking the direct contact between the corrosive medium in the use environment and the fixed portion 1.2.1, and can significantly reduce the risk of the tooth 1.2 falling off; 3) In the stamping process, the bent portion 1.2.4 is mechanically interlocked with the inner wall of the half-tube portion 1.1.1. Synchronous collaborative processing is implemented in the forming process. While completing the bending of the discharge tip 1.2.3, the bent portion 1.2.4 is mechanically interlocked with the inner wall of the half-tube portion 1.1.1. The two processing operations are combined into one operation, which can improve the overall processing efficiency. This can be achieved through the optimization design of the mold structure, reducing the cost of equipment modification without affecting the production cycle time. 4) Through process layout optimization, the process of enclosing and welding the tube blank half-blank 1.1 to form the tube blank 1.3, which originally required pre-placement, is integrated into this process. This can reduce the part processing requirements before this process and reduce the part processing time and cost.

[0035] Preferably, in step 100: the tube blank half 1.1 is formed by a metal sheet through a stamping process, and the serrations 1.2 are formed by a metal sheet through a blanking process.

[0036] Example 2: like Figure 2 As shown, a manufacturing process of an electrostatic precipitator RS line includes the following steps: Step 100: Using a metal sheet stamping and blanking process, a tube half blank 1.1 and a tooth 1.2 are formed. The tube half blank 1.1 includes a half tube portion 1.1.1 and side portions 1.1.2 located on opposite sides of the half tube portion 1.1.1. The tooth 1.2 includes a fixing portion 1.2.1 and a discharge portion 1.2.2 having a discharge tip 1.2.3. Step 200: conveying and welding the serrations 1.2 to corresponding positions of the side portions 1.1.2 of the first tube half 1.1; Step 300: Stamp and form the barbs 1.2 provided on the first semi-finished tube blank 1.1, causing the discharge tips 1.2.3 of the barbs 1.2 to bend, and causing the fixing portions 1.2.1 of the barbs 1.2 to bend near one end of the semi-tube portion 1.1.1 to form bent portions 1.2.4. The bent portions 1.2.4 abut against the inner wall of the semi-tube portion 1.1.1. At the same time, stamp the position on the side portion 1.1.2 where the barbs 1.2 are installed, causing the position on the side portion 1.1.2 where the barbs 1.2 are installed to sink to form an installation groove 1.1.3 for accommodating the barbs 1.2, and making the upper surface of the fixing portion 1.2.1 flush with the upper surface of the side portion 1.1.2 at the position not connected to the barbs 1.2, so that the bending position of at least one of the discharge tips 1.2.3 abuts against the end of the side portion 1.1.2 away from the semi-tube portion 1.1.1, as Figure 14 shown, so that the discharge tip 1.2.3 and the bent portion 1.2.4 clamp the side portion 1.1.2 from opposite sides; Step 400: After sequentially completing the conveying and stamping of multiple barbs 1.2, butt-join the second semi-finished tube blank 1.1 with the first semi-finished tube blank 1.1, and weld the side portions 1.1.2 of the two to form a tube blank 1.3. The side portions 1.1.2 of the first semi-finished tube blank 1.1 and the side portions 1.1.2 of the second semi-finished tube blank 1.1 cover the fixing portion 1.2.1; Step 500: Stamp and form the end of the tube blank 1.3 into a flat connecting portion 1.3.1 by a press head machine 6; Step 600: Process connection holes in the connecting portion by a blanking process or a drilling process.

[0037] Adopting the foregoing technical solution, first weld the barbs 1.2 on the side part 1.1.2 of the first half blank of the tube blank 1.1, and then perform operations such as stamping and forming. This can preliminarily fix the position of the barbs 1.2 on the half blank of the tube blank 1.1, facilitating the subsequent accurate stamping and forming of the barbs 1.2, bending the discharge tip 1.2.3 of the barbs 1.2, and forming a bent part 1.2.4 on the fixing part 1.2.1. Moreover, it can better control the abutting position and state between the bent part 1.2.4 and the inner wall of the half tube part 1.1.1, which is beneficial to achieving the expected mechanical fitting effect. By means of the step of stamping and forming the barbs 1.2 to synchronously form the installation groove 1.1.3, there is no need to add new processes and additional components, avoiding the cost increase caused by introducing new components. At the same time, it will not affect the overall production efficiency, achieving multiple process objectives without additional consumption of resources and time. Meanwhile, the installation groove 1.1.3 enables the fixing part 1.2.1 of the barbs 1.2 to be located within the installation groove 1.1.3. When the two half blanks of the tube blank 1.1 are enclosed, it can effectively restrict the movement of the barbs 1.2 in the length direction of the tube blank 1.3, enhancing the stability of the barbs 1.2 on the tube blank 1.3. When the two half blanks of the tube blank 1.1 are butted, since the upper surface of the fixing part 1.2.1 is flush with the upper surface of the side part 1.1.2 of the position not connected to the barbs 1.2, the second half blank of the tube blank 1.1 can be directly and seamlessly butted with the first half blank of the tube blank 1.1 without any additional processing in the subsequent process. The above technical solution also eliminates the possible structural differences between the two half blanks of the tube blank 1.1 before entering this process. The two half blanks of the tube blank 1.1 can be completely replaced with each other, reducing the number of parts and further lowering the production cost. The existence of the installation groove 1.1.3 can effectively restrict the movement of the barbs 1.2 in the length direction of the tube blank 1.3, enhancing the stability of the barbs 1.2 on the tube blank 1.3.

[0038] Embodiment 3: As Figure 3 shown: A manufacturing process for the R-S line of an electrostatic precipitator includes the following steps: Step 100: Process the half blank of the tube blank 1.1 and the barbs 1.2 by using metal sheet stamping and blanking processes. The half blank of the tube blank 1.1 includes a half tube part 1.1.1 and side parts 1.1.2 located on opposite sides of the half tube part 1.1.1. The barbs 1.2 include a fixing part 1.2.1 and a discharge part 1.2.2 having a discharge tip 1.2.3; Step 150: Through the stamping equipment 10, stamp and form a number of installation grooves 1.1.3 for accommodating the barbs 1.2 on the side part 1.1.2; Step 200: Transport the barbs 1.2 to the side part 1.1.2 of the first semi-finished tube blank 1.1, place the fixing part 1.2.1 of the barbs 1.2 in the corresponding installation groove 1.1.3, and make the upper surface of the fixing part 1.2.1 flush with the upper surface of the side part 1.1.2 where the installation groove 1.1.3 is not formed; Step 300: After sequentially completing the transportation and stamping of multiple barbs 1.2, perform stamping and forming on the barbs 1.2 installed on the first semi-finished tube blank 1.1, so that the discharge tip 1.2.3 of the barbs 1.2 is bent, and the end of the fixing part 1.2.1 of the barbs 1.2 close to the semi-tube part 1.1.1 is bent to form a bent part 1.2.4, and the bent part 1.2.4 abuts against the inner wall of the semi-tube part 1.1.1; Step 400: Dock the second semi-finished tube blank 1.1 with the first semi-finished tube blank 1.1, and weld the side parts 1.1.2 of the two to form a tube blank 1.3. The side parts 1.1.2 of the first semi-finished tube blank 1.1 and the side parts 1.1.2 of the second semi-finished tube blank 1.1 cover the fixing part 1.2.1; Step 500: Use a press head machine 6 to stamp the end of the tube blank 1.3 into a flat connecting part; Step 600: Process connection holes in the connecting part by blanking process or drilling process.

[0039] With the foregoing technical solution, by stamping and forming the installation groove 1.1.3 in the side part 1.1.2 in advance, the position, size, and shape of the installation groove 1.1.3 can be controlled more precisely, ensuring that each barb 1.2 can be accurately placed in the corresponding installation groove 1.1.3, thereby improving the installation accuracy and consistency of the barbs 1.2. This helps to ensure the quality stability of the R-S line and reduce performance differences caused by deviation in the installation position of the barbs 1.2. Since the installation groove 1.1.3 is stamped and formed in a separate step, it is convenient to inspect and control the quality of the installation groove 1.1.3 in this step, and promptly discover and correct possible problems, such as size deviation and irregular shape of the installation groove 1.1.3, which is beneficial to improving the yield rate of the product.

[0040] Preferably, in Step 300, when performing stamping and forming, make the bending position of at least one of the discharge tips 1.2.3 close to the end of the side part 1.1.2 away from the semi-tube part 1.1.1, so that the discharge tip 1.2.3 and the bent part 1.2.4 clamp the side part 1.1.2 from opposite sides.

[0041] With the foregoing technical solution, the bending positions of at least one discharge tip 1.2.3 are pressed against the end of the side part 1.1.2 away from the semi-tube part 1.1.1, and the discharge tip 1.2.3 and the bending part 1.2.4 clamp the side part 1.1.2 from opposite sides, forming a structure similar to "clamping". This structure greatly increases the connection strength between the spike teeth 1.2 and the side part 1.1.2 of the semi-finished tube blank 1.1 of the tube blank, effectively preventing the spike teeth 1.2 from falling off the side part 1.1.2 due to external forces during use, and improving the stability and reliability of the overall structure of the R-S line. This clamping form is equivalent to providing a redundant design for the connection between the spike teeth 1.2 and the semi-finished tube blank 1.1 of the tube blank, adding an extra safeguard for the connection between the spike teeth 1.2 and the semi-finished tube blank 1.1 of the tube blank. Even if there are problems with the welded part, the clamping structure can still play a role, effectively delaying equipment failures caused by the falling off of the spike teeth 1.2, extending the overall service life of the electrostatic precipitator, reducing the frequency of equipment maintenance and replacement, and lowering the maintenance cost.

[0042] Embodiment 4: As Figure 4 shown: A manufacturing process for the R-S line of an electrostatic precipitator includes the following steps: Step 100: Use metal sheet stamping and blanking processes to process the semi-finished tube blank 1.1 and the spike teeth 1.2. The semi-finished tube blank 1.1 includes a semi-tube part 1.1.1 and side parts 1.1.2 located on opposite sides of the semi-tube part 1.1.1. The semi-finished tube blank 1.1 is divided into a first semi-finished tube blank 1.1 and a second semi-finished tube blank 1.1. A plurality of mounting grooves 1.1.3 for accommodating the spike teeth 1.2 are provided on the side part 1.1.2 of the first semi-finished tube blank 1.1. The spike teeth 1.2 include a fixing part 1.2.1 and a discharging part 1.2.2 having a discharge tip 1.2.3. Step 200: Transport the spike teeth 1.2 to the side part 1.1.2 of the first semi-finished tube blank 1.1, place the fixing part 1.2.1 of the spike teeth 1.2 in the corresponding mounting groove 1.1.3, and make the upper surface of the fixing part 1.2.1 flush with the upper surface of the side part 1.1.2 where the mounting groove 1.1.3 is not formed. Step 300: After sequentially completing the transportation and stamping of multiple spike teeth 1.2, perform stamping on the spike teeth 1.2 mounted on the first semi-finished tube blank 1.1 to bend the discharge tip 1.2.3 of the spike teeth 1.2, and bend one end of the fixing part 1.2.1 of the spike teeth 1.2 close to the semi-tube part 1.1.1 to form a bending part 1.2.4, and the bending part 1.2.4 abuts against the inner wall of the semi-tube part 1.1.1. Step 400: butting the second tube half 1.1 against the first tube half 1.1, and welding their side portions 1.1.2 to form a tube 1.3. The side portions 1.1.2 of the first tube half 1.1 and the side portions 1.1.2 of the second tube half 1.1 cover the fixing portion 1.2.1. Step 500: Using a punching machine 6, the end of the tube blank 1.3 is punched into a flat connecting portion; Step 600: Processing a connection hole at the connection portion by a punching process or a drilling process.

[0043] By adopting the aforementioned technical solution, the installation groove 1.1.3 is set when the tube blank half-blank 1.1 is processed in step 100, and the processing of the installation groove 1.1.3 is integrated into the initial processing link of the tube blank half-blank 1.1, further simplifying the overall production process. Compared with the subsequent separate steps to stamp the installation groove 1.1.3, this method makes the entire manufacturing process more compact and coherent, reduces the connection time between processes, and improves production efficiency. The processing of the installation groove 1.1.3 is carried out simultaneously with the processing of the tube blank half-blank 1.1, and no additional equipment and complex operations are required to stamp the installation groove 1.1.3 separately. This not only reduces the difficulty of processing and reduces the equipment investment and labor costs that may be caused by adding processes, but also reduces the scrap rate caused by operational errors in multiple steps, thereby further reducing production costs.

[0044] Preferably, in step 300, during the stamping process, the bent position of at least one of the discharge tips 1.2.3 is brought into close contact with the end of the side portion 1.1.2 away from the half-tube portion 1.1.1, so that the discharge tip 1.2.3 and the bent portion 1.2.4 clamp the side portion 1.1.2 from opposite sides.

[0045] Using the aforementioned technical solution, the curved portion of at least one discharge tip 1.2.3 abuts the end of the side portion 1.1.2 away from the half-tube portion 1.1.1. Furthermore, the discharge tip 1.2.3 and the bent portion 1.2.4 clamp the side portion 1.1.2 from opposite sides, forming a structure similar to a "clamp." This structure significantly strengthens the connection between the serration 1.2 and the side portion 1.1.2 of the tube half 1.1, effectively preventing the serration 1.2 from falling off the side portion 1.1.2 during use due to external forces, thereby enhancing the stability and reliability of the RS line's overall structure. This clamping design provides a redundant design for the connection between the serration 1.2 and the tube half 1.1, adding a layer of security to the connection. Even if problems arise with the weld, the clamping structure remains functional, effectively delaying equipment failures caused by the serration 1.2 falling off, extending the overall service life of the electrostatic precipitator, reducing the frequency of equipment repairs and replacements, and lowering maintenance costs.

[0046] Example 5: As Figure 5 shown, a manufacturing process for the R - S line of an electrostatic precipitator includes the following steps: Step 100: Use metal sheet stamping and blanking processes to process the tube blank semi - part 1.1 and the spike teeth 1.2. The tube blank semi - part 1.1 includes a semi - tube part 1.1.1, side parts 1.1.2 located on opposite sides of the semi - tube part 1.1.1, and a plurality of mounting grooves 1.1.3 provided on the side parts 1.1.2 for accommodating the spike teeth 1.2. The spike teeth 1.2 include a fixing part 1.2.1 and a discharging part 1.2.2 with a discharging tip 1.2.3. The depth of the mounting groove 1.1.3 is equal to half of the thickness of the fixing part 1.2.1; Step 200: Transport and weld the spike teeth 1.2 to the side part 1.1.2 of the first tube blank semi - part 1.1, so that the fixing part 1.2.1 of the spike teeth 1.2 is placed in the corresponding mounting groove 1.1.3; Step 300: Perform stamping on the spike teeth 1.2 mounted on the first tube blank semi - part 1.1, so that the discharging tip 1.2.3 of the spike teeth 1.2 is bent, and one end of the fixing part 1.2.1 of the spike teeth 1.2 close to the semi - tube part 1.1.1 is bent to form a bent part 1.2.4. The bent part 1.2.4 abuts against the inner wall of the semi - tube part 1.1.1, and the bending position of at least one discharging tip 1.2.3 is close to the end of the side part 1.1.2 away from the semi - tube part 1.1.1. As Figure 2 shown, so that the discharging tip 1.2.3 and the bent part 1.2.4 clamp the side part 1.1.2 from opposite sides; Step 400: Dock the second tube blank semi - part 1.1 with the first tube blank semi - part 1.1, align the mounting groove 1.1.3 on the second tube blank semi - part 1.1 with the fixing part 1.2.1 of the corresponding spike teeth 1.2, and weld the side parts 1.1.2 of the two to form a tube blank part 1.3. The side part 1.1.2 of the first tube blank semi - part 1.1 and the side part 1.1.2 of the second tube blank semi - part 1.1 cover the fixing part 1.2.1; Step 500: Use a press head machine 6 to stamp the end of the tube blank part 1.3 into a flat connecting part; Step 600: Process connecting holes in the connecting part by blanking process or drilling process.

[0047] Preferably, in step 300, when performing stamping, the bending position of at least one discharging tip 1.2.3 is close to the end of the side part 1.1.2 away from the semi - tube part 1.1.1, so that the discharging tip 1.2.3 and the bent part 1.2.4 clamp the side part 1.1.2 from opposite sides.

[0048] Adopting the foregoing technical solution, the bending position of at least one discharge tip 1.2.3 is pressed against the end of the side part 1.1.2 away from the semi-tube part 1.1.1, and the discharge tip 1.2.3 and the bending part 1.2.4 clamp the side part 1.1.2 from opposite sides, forming a structure similar to "clamping". This structure greatly increases the connection strength between the spike teeth 1.2 and the side part 1.1.2 of the tube blank semi-blank 1.1, effectively preventing the spike teeth 1.2 from falling off the side part 1.1.2 due to external forces during use, and improving the stability and reliability of the overall structure of the R-S line. This clamping form is equivalent to providing a redundant design for the connection between the spike teeth 1.2 and the tube blank semi-blank 1.1, adding an extra safeguard for the connection between the spike teeth 1.2 and the tube blank semi-blank 1.1. Even if there are problems with the welded part, the clamping structure can still function, effectively delaying equipment failures caused by the falling off of the spike teeth 1.2, extending the overall service life of the electrostatic precipitator, reducing the frequency of equipment maintenance and replacement, and lowering the maintenance cost.

[0049] Embodiment 6: As Figure 2 and Figure 5 shown, an R-S line production device for an electrostatic precipitator, which is applicable to the above-mentioned R-S line manufacturing process for an electrostatic precipitator, includes a frame 2, a tube blank transmission line 3 for transmitting the tube blank semi-blank 1.1 and the tube blank 1.3, and a feeding device 4, a loading device 7, a second welding machine 11, and a pressing head machine 6 arranged in sequence along the transmission direction of the tube blank transmission line 3. The tube blank transmission line 3 is installed on the frame 2; it further includes a first welding machine 5 and a forming machine 9 as Figure 11 shown. The feeding device 4 and the first welding machine 5 are arranged on opposite sides of the same processing station of the tube blank transmission line 3, and the forming machine 9 is arranged downstream of the first welding machine 5 and upstream of the loading device 7.

[0050] With the foregoing technical solution, the above production equipment can achieve the processing of the new R-S wire 1. The first welding machine 5 and the second welding machine 11 can be spot welding machines, laser welding machines, or other commonly used welding machines. In the above first solution, the production equipment includes a forming machine 9. When the tube blank transmission line 3 conveys the first tube blank semi-finished part 1.1 to the position of the feeding device 4, the feeding device 4 sequentially sends out a plurality of barbs 1.2. The forming machine 9 performs stamping on the barbs 1.2 placed on the first tube blank semi-finished part 1.1, so that the discharge tip 1.2.3 of the barb 1.2 is bent, and the fixing part 1.2.1 of the barb 1.2 is bent near one end of the semi-tube part 1.1.1 to form a bent part 1.2.4, and the bent part 1.2.4 abuts against the inner wall of the semi-tube part 1.1.1; then the tube blank transmission line 3 conveys the first tube blank semi-finished part 1.1 to the position where the feeding device 7 is arranged. The feeding device 7 sends out the second tube blank semi-finished part 1.1, and docks the second tube blank semi-finished part 1.1 with the first tube blank semi-finished part 1.1. Then the tube blank transmission line 3 conveys the two tube blank semi-finished parts 1.1 to the position where the second welding machine 11 is arranged. The second welding machine 11 welds and fixes the second tube blank semi-finished part 1.1 and the first tube blank semi-finished part 1.1 to form a tube blank part 1.3, and the side part 1.1.2 of the first tube blank semi-finished part 1.1 and the side part 1.1.2 of the second tube blank semi-finished part 1.1 cover and clamp the fixing part 1.2.1; the tube blank transmission line 3 conveys the tube blank part 1.3 to the position where the press head machine 6 is arranged, and then the press head machine 6 stamps the end of the tube blank part 1.3 into a flat connecting part 1.3.1. The tube blank transmission line 3 continues to convey and sends out the processed R-S wire 1 from the above production equipment.In the second solution mentioned above, when the production equipment includes the first welding machine 5 and the forming machine 9, when the tube blank transfer line 3 transports the first tube blank semi-finished part 1.1 to the position of the feeding device 4, the feeding device 4 sequentially sends out a plurality of barbs 1.2. The first welding machine 55 sequentially welds the plurality of barbs 1.2 at the corresponding positions on the side part 1.1.2 of the first tube blank semi-finished part 1.1. The tube blank transfer line 3 transports the first tube blank semi-finished part 1.1 to the position where the forming machine 9 is set. The forming machine 9 performs stamping on the barbs 1.2 installed on the first tube blank semi-finished part 1.1, causing the discharge tip 1.2.3 of the barb 1.2 to bend, and causing the fixing part 1.2.1 of the barb 1.2 to bend near one end of the semi-tube part 1.1.1 to form a bent part 1.2.4. The bent part 1.2.4 abuts against the inner wall of the semi-tube part 1.1.1. During this process, the forming machine 9 can also synchronously perform stamping on the position where the barb 1.2 is installed on the side part 1.1.2, causing the position where the barb 1.2 is installed on the side part 1.1.2 to sink to form an installation groove 1.1.3 for accommodating the barb 1.2. The tube blank transfer line 3 transports the tube blank semi-finished part 1.1 to the position where the feeding device 7 is set. The feeding device 7 sends out the second tube blank semi-finished part 1.1 and docks the second tube blank semi-finished part 1.1 with the first tube blank semi-finished part 1.1. Then the tube blank transfer line 3 transports the two tube blank semi-finished parts 1.1 to the position where the second welding machine 11 is set. The second welding machine 11 welds and fixes the second tube blank semi-finished part 1.1 and the first tube blank semi-finished part 1.1 to form a tube blank part 1.3, and causes the side part 1.1.2 of the first tube blank semi-finished part 1.1 and the side part 1.1.2 of the second tube blank semi-finished part 1.1 to wrap and clamp the fixing part 1.2.1. The tube blank transfer line 3 continues to transport the tube blank semi-finished part 1.1 to the position where the press head machine 6 is set, and then the press head machine 6 stamps the end of the tube blank part 1.3 into a flat connecting part 1.3.1. The tube blank transfer line 3 continues to transport and sends out the processed R-S line 1 from the above production equipment.

[0051] In another embodiment, it further includes a stamping device 10, and the stamping device 10 is arranged upstream of the feeding device 4.

[0052] In the above technical solution, the tube blank transfer line 3 transports the first tube blank semi-finished part 1.1 to the position where the stamping device 10 is set. The stamping device 10 stamps and forms a plurality of installation grooves 1.1.3 for accommodating the barbs 1.2 on the side part 1.1.2. Then the tube blank transfer line 3 transports the first tube blank semi-finished part 1.1 to the position where the feeding device 4 is set. The feeding device 4 sequentially sends out a plurality of barbs 1.2 to the installation grooves 1.1.3.

[0053] Preferably, in order to increase the welding efficiency, a second welding machine 11 can be arranged on each of the opposite sides of the tube blank transfer line 3 to weld the side parts 1.1.2 on both sides respectively.

[0054] Example 7: As Figure 1 , Figure 3 and Figure 4 shown: A production device for the R-S line 1 of an electrostatic precipitator, applicable to the above-mentioned manufacturing process of the R-S line of the electrostatic precipitator, includes a frame 2, a tube blank transmission line 3 for transporting the tube blank semi-finished parts 1.1 and the tube blank parts 1.3, and a feeding device 4, a loading device 7, a second welding machine 11, and a pressing head machine 6 arranged in sequence along the transmission direction of the tube blank transmission line 3. The tube blank transmission line 3 is installed on the frame 2; it also includes a forming machine 9 as Figure 11 shown. The feeding device 4 and the forming machine 9 are arranged on opposite sides of the same processing station of the tube blank transmission line 3.

[0055] The above production device can realize the processing of the new R-S line 1. The first welding machine 5 and the second welding machine 11 can be spot welding machines, laser welding machines, or other common welding machines. When the tube blank transmission line 3 transports the first tube blank semi-finished part 1.1 to the position of the feeding device 4, the feeding device 4 sequentially sends out a plurality of barbs 1.2. The forming machine 9 presses and forms the barbs 1.2 placed on the first tube blank semi-finished part 1.1, bends the discharge tips 1.2.3 of the barbs 1.2, and bends one end of the fixing part 1.2.1 of the barbs 1.2 close to the semi-tube part 1.1.1 to form a bent part 1.2.4. The bent part 1.2.4 abuts against the inner wall of the semi-tube part 1.1.1; then the tube blank transmission line 3 transports the first tube blank semi-finished part 1.1 to the position where the loading device 7 is set. The loading device 7 sends out the second tube blank semi-finished part 1.1, docks the second tube blank semi-finished part 1.1 with the first tube blank semi-finished part 1.1, and then the tube blank transmission line 3 transports the two tube blank semi-finished parts 1.1 to the position where the second welding machine 11 is set. The second welding machine 11 welds and fixes the second tube blank semi-finished part 1.1 and the first tube blank semi-finished part 1.1 to form the tube blank part 1.3, and makes the side part 1.1.2 of the first tube blank semi-finished part 1.1 wrap and clamp the fixing part 1.2.1 with the side part 1.1.2 of the second tube blank semi-finished part 1.1; the tube blank transmission line 3 transports the tube blank part 1.3 to the position where the pressing head machine 6 is set, and then the pressing head machine 6 presses and forms the end of the tube blank part 1.3 into a flat connecting part. The tube blank transmission line 3 continues to transport and sends out the processed R-S line 1 from the above production device.

[0056] It can be understood that in another embodiment, it also includes a stamping device 10, and the stamping device 10 is arranged upstream of the feeding device 4.

[0057] In the above technical solution, the tube blank transfer line 3 conveys the first tube blank semi-finished part 1.1 to the position where the stamping device 10 is arranged. The stamping device 10 stamps and forms a plurality of installation grooves 1.1.3 for accommodating the awn teeth 1.2 at the side part 1.1.2. Then, the tube blank transfer line 3 conveys the first tube blank semi-finished part 1.1 to the position where the feeding device 4 is arranged, and the feeding device 4 sequentially sends out a plurality of awn teeth 1.2 into the installation grooves 1.1.3. When the forming machine 9 stamps and forms the awn teeth 1.2, there is no need to stamp and generate the installation grooves 1.1.3 again.

[0058] Embodiment 8: On the basis of Embodiment 6 or Embodiment 7, as Figure 11 shown, the forming machine 9 includes a fixed frame 9.1, an upper lifting driver 9.2, an upper die 9.3, a lower die 9.4 and a lower lifting driver 9.5. The upper lifting driver 9.2 is installed on the fixed frame 9.1 and drives the upper die 9.3 to lift and lower. The lower lifting driver 9.5 is installed on the fixed frame 9.1 and drives the lower die 9.4 to lift and lower. After the upper die 9.3 and the lower die 9.4 are closed, they enclose a forming cavity for accommodating the awn teeth 1.2. The upper die 9.3 is provided with a first extrusion block 9.3.1 for downwardly extruding the bending part 1.2.4 and a second extrusion block 9.3.2 for downwardly extruding the fixing part 1.2.1 and the side part 1.1.2. A concave groove is provided at the position of the lower die 9.4 corresponding to the second extrusion block 9.3.2.

[0059] Adopting the foregoing technical solution, the forming machine 9 controls the lifting and lowering of the upper die 9.3 and the lower die 9.4 respectively through the upper lifting driver 9.2 and the lower lifting driver 9.5, and can accurately control the speed, pressure and position of die closing. This enables the bending angle of the discharge tip 1.2.3 of the awn teeth 1.2 and the shape and position of the bending part 1.2.4 formed by bending the fixing part 1.2.1 to be accurately controlled during the stamping and forming process of the awn teeth 1.2, ensuring the consistency and accuracy of the forming of the awn teeth 1.2, and being beneficial to improving the overall quality and performance of the R-S line. The forming machine 9 in the above technical solution can stamp and form the awn teeth 1.2 arranged on the first tube blank semi-finished part 1.1 during stamping, bend the discharge tip 1.2.3 of the awn teeth 1.2, and bend one end of the fixing part 1.2.1 of the awn teeth 1.2 close to the semi-tube part 1.1.1 to form a bending part 1.2.4. The bending part 1.2.4 abuts against the inner wall of the semi-tube part 1.1.1. It can also synchronously stamp the position where the awn teeth 1.2 are installed on the side part 1.1.2, and make the position where the awn teeth 1.2 are installed on the side part 1.1.2 concave to form an installation groove 1.1.3 for accommodating the awn teeth 1.2.

[0060] Preferably, as Figures 1 to 5As shown, the loading device 7 includes a stacking rack 7.1, a first pushing mechanism 7.2, a second pushing mechanism 7.3 and a guide frame 7.4. The stacking rack 7.1 is provided with a discharge port 7.5 at the bottom. The first pushing mechanism 7.2 is arranged at a position corresponding to the discharge port 7.5, and is used to push the tube blank half billet 1.1 located at the bottom of the stacking rack 7.1 to the guide frame 7.4. The second pushing mechanism 7.3 is arranged at a position corresponding to the guide frame 7.4, and is used to push the tube blank half billet 1.1 on the guide frame 7.4 to the loading station. A positioning block 7.6 is provided on the side of the tube blank transmission line 3 away from the guide frame 7.4. The pushing directions of the first pushing mechanism 7.2 and the second pushing mechanism 7.3 are vertical.

[0061] Using the aforementioned technical solution, the stacking rack 7.1 can store multiple tube semi-billets 1.1. The first ejection mechanism 7.2 can sequentially eject the tube semi-billets 1.1 at the bottom of the stacking rack 7.1 onto the guide rack 7.4, enabling automatic loading, reducing manual operation, and improving loading efficiency. The guide rack 7.4 guides the tube semi-billets 1.1, allowing them to be accurately ejected to the loading station. Simultaneously, a positioning block 7.6, located on the side of the tube conveyor line 3 facing away from the guide rack 7.4, precisely positions the tube semi-billets 1.1, ensuring their accurate positioning during subsequent processing, thereby improving processing accuracy and product quality. The ejection directions of the first ejection mechanism 7.2 and the second ejection mechanism 7.3 are perpendicular. This design allows for smooth ejection of the tube semi-billets 1.1 in different directions, better adapting to the transport direction of the tube conveyor line 3 and the position requirements of the loading station, thereby increasing the flexibility and adaptability of the loading device 7.

[0062] It is understood that a loading device 7 may also be provided upstream of the feeding device 4 to provide the first tube half 1.1 to the tube transfer line 3. The opening of the half tube portion 1.1.1 of the tube half 1.1 in the loading device 7 upstream of the feeding device 4 faces upward, while the opening of the half tube portion 1.1.1 of the tube half 1.1 in the loading device 7 downstream of the feeding device 4 faces downward.

[0063] Specifically, the tube half pieces 1.1 are stacked vertically in the stacking rack 7.1. Since the outer diameter of the half tube portion 1.1.1 is larger than the inner diameter, gaps will appear in the vertical direction when the tube half pieces 1.1 are stacked vertically.

[0064] In one embodiment based on Embodiment 8, the feeding device 7 further includes a blanking control mechanism 8. The blanking control mechanism 8 drives a limit gear 8.7 to rotate through a motor. The tooth pitch of the limit gear 8.7 matches the gap in the vertical direction when the semi-finished pipe blanks 1.1 are stacked vertically, so that the pushed semi-finished pipe blanks 1.1 do not contact the semi-finished pipe blanks 1.1 above, avoiding scratching of the semi-finished pipe blanks 1.1 when being dragged by the semi-finished pipe blanks 1.1 above, and also avoiding the situation that it is difficult to be pushed out due to being pressed by the semi-finished pipe blanks 1.1 above.

[0065] In another embodiment based on Embodiment 8, as Figures 6 to 10 shown, the feeding device 7 further includes a blanking control mechanism 8. The blanking control mechanism 8 includes a fixed block 8.1, a chute 8.0 provided in the fixed block 8.1, a moving block 8.2, a fixed rack 8.3, a sliding rack 8.4, a first spring 8.5, a second spring 8.6 and a limit gear 8.7. The limit gear 8.7 is rotatably connected to the stacking rack 7.1, and one tooth of the limit gear 8.7 supports the semi-finished pipe blank 1.1 located in the stacking rack 7.1. The fixed block 8.1 is fixed to the stacking rack 7.1. The fixed rack 8.3 and the sliding rack 8.4 are arranged side by side on the moving block 8.2. The fixed rack 8.3 is fixed to the moving block 8.2. The sliding rack 8.4 is slidably connected to the moving block 8.2 and has a first position and a second position. The second spring 8.6 is provided between the sliding rack 8.4 and the moving block 8.2 to keep the sliding rack 8.4 in the first position. The moving block 8.2 is slidably connected to the chute 8.0 in the fixed block 8.1 and has a locking position where the fixed rack 8.3 meshes with the limit gear 8.7 and an unlocking position where the sliding rack 8.4 meshes with the limit gear 8.7. The first spring 8.5 is provided between the fixed block 8.1 and the moving block 8.2 to keep the moving block 8.2 in the locking position. When the sliding rack 8.4 switches from the first position to the second position, the sliding rack 8.4 moves a distance of one tooth pitch. When the telescopic rod of the first pushing mechanism 7.2 retracts, the telescopic rod abuts against and moves the moving block 8.2 to the unlocking position.

[0066] Adopting the foregoing technical solution, the specific steps are as follows: When the telescopic rod of the first pushing mechanism 7.2 retracts after the pushing action, as Figures 7 to 8 shown, it will abut against and pull the moving block 8.2 to move to the unlocking position (the limit gear 8.7 and the sliding rack 8.4 are meshed). At this time, the first spring 8.5 will be in a stretched state. Due to the sliding rack 8.4 being pressed by the gravity of the semi-finished pipe blank 1.1 and rotating a tooth stroke, the sliding rack 8.4 moves down a distance of one tooth and touches the bottom wall of the sliding groove where the sliding rack 8.4 is located, that is, the second position of the sliding rack 8.4 (as Figure 9 and Figure 10As shown, the second spring 8.6 is compressed. At this time, after the lowermost half billet 1.1 of the tube blank loses the limitation of the limiting gear 8.7, it falls to the discharge port 7.5 to complete the blanking operation. Subsequently, as Figures 9 to 10 shown, the first spring 8.5 will pull the moving block 8.2 to move to the locked position (the limiting gear 8.7 and the fixed rack 8.3 are engaged). At this time, after the second spring 8.6 extends, it will push the moving rack 8.4 to the initial first position (as Figure 7 and Figure 8 shown).

[0067] One tooth of the limiting gear 8.7 supports the half billet 1.1 of the tube blank. Only when the sliding rack 8.4 switches positions and meshes with the limiting gear 8.7 to rotate, will a half billet 1.1 of the tube blank be released, effectively avoiding the situation of over blanking or inaccurate blanking, and ensuring the accuracy and stability of feeding. By using the design that when the telescopic rod of the first pushing mechanism 7.2 retracts, it abuts against and makes the moving block 8.2 move to the unlocking position, the automatic triggering of blanking is realized. Without additional control systems or manual intervention, the entire feeding process becomes more automated and smooth, reducing the workload and error probability of manual operations, improving production efficiency, and being more stable when controlling the fall of the half billet 1.1 of the tube blank. It can accurately trigger the rotation of the limiting gear 8.7 after the telescopic rod retracts, so that the corresponding half billet 1.1 of the tube blank falls to the designated position.

[0068] Preferably, the number of the blanking control mechanisms 8 is two, and the two blanking control mechanisms 8 are arranged on the opposite sides of the feeding device 7. The blanking control mechanism 8 further includes at least one second gear, the second gear is rotatably connected to the stacking rack 7.1, the second gear and the limiting gear 8.7 are arranged at intervals along the telescopic direction of the telescopic rod, and the second gear and the limiting gear 8.7 are coaxially fixed through a coupling 8.8.

[0069] The steps in the above flow chart are aligned end to end. There are gaps between the upstream and downstream racks 2 of the press head machine 6, the first welding machine 5 and the second welding machine 11 for the press head machine 6, the first welding machine 5 and the second welding machine 11 to work; for the above-mentioned conveying device that conveys the barbs 1.2 onto the tube blank, after the barbs 1.2 are conveyed to the designated position, the conveying end of the conveying device will descend to avoid the barbs 1.2 moving along the conveying line.

[0070] In addition to the above preferred embodiments, the present application has other implementation manners. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection requested by the present application.
