Description

Technical Field

[0001] This application relates to the field of electrostatic precipitator technology, and in particular to a manufacturing process and production equipment for an electrostatic precipitator RS line. Background Technology

[0002] RS wire, as one of the commonly used cathode wires in electrostatic precipitators, has various structural forms, which can be generally divided into two categories: integral welding and split welding. Integral welding is achieved by punching two halves on the same sheet metal, forming and welding them together; this method has a low material utilization rate. Split welding involves fabricating the toothed parts, tube blanks, and connecting pipes separately and then welding them together.

[0003] Chinese patent application publication number CN101862958A discloses "A special machine for automatically producing RS lines for electrostatic precipitators." This machine improves upon traditional production processes, integrates production steps, and enhances production efficiency and product quality. However, the teeth of the RS lines produced are directly welded to the outside of the tube blank. Because the RS lines are exposed to corrosive gases for extended periods in the working environment of electrostatic precipitators, the welded area between the teeth and the tube blank is prone to corrosion during use, causing the teeth to fall off and thus reducing the service life of the RS lines. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of the prior art and provide a manufacturing process and production equipment for RS wires in electrostatic precipitators. This process and equipment can automatically produce RS wires with the side of the tube blank covered with a toothed fixing part, thereby improving the service life of RS wires in corrosive environments.

[0005] To achieve the above objectives, this application adopts the following technical solution: a manufacturing process for an RS wire of an electrostatic precipitator, comprising the following steps:

[0006] Step 100: Use metal parts to process a tube blank half-blank and a toothed part. The tube blank half-blank includes a half-tube part and side parts located on opposite sides of the half-tube part. The toothed part includes a fixing part and a discharge part with a discharge tip.

[0007] Step 200: The toothed part is conveyed to the corresponding position on the side of the first tube blank half-blank;

[0008] Step 300: The teeth set on the first tube blank half blank are stamped and formed, so that the discharge tip of the teeth is bent and the fixed part of the teeth is bent at the end near the half tube to form a bent part, and the bent part abuts against the inner wall of the half tube.

[0009] Step 400: After the multiple teeth are conveyed and stamped in sequence, the second tube blank half-blank is joined with the first tube blank half-blank, and the sides of the two are welded to form a tube blank. The side of the first tube blank half-blank and the side of the second tube blank half-blank cover the fixing part.

[0010] Step 500: The end of the tube blank is stamped into a flat connecting part by a press head machine.

[0011] The aforementioned manufacturing process for the RS line of the electrostatic precipitator achieves a dual improvement in product reliability and production efficiency through structural optimization and process integration. Its core innovations are: 1) The adoption of a double-sided tube blank half-blank side enclosure structure completely covers the fixing part of the tooth between the two sides, forming a physical isolation barrier, effectively blocking the direct contact between corrosive media in the use environment and the fixing part, and significantly reducing the risk of tooth detachment; 2) The bending part and the inner wall of the half-tube form a mechanical fit, and this structure can still provide reliable pull-out resistance when the connection between the fixing part and the side part fails; 3) Synchronous and collaborative processing is implemented in the stamping process, and the bending part and the inner wall of the half-tube form a mechanical fit at the same time as completing the bending of the discharge tip, merging the two processing operations into one operation, which can improve the overall processing efficiency. This can be achieved through mold structure optimization design, reducing equipment modification costs, and not affecting production cycle time; 4) By optimizing the process layout, the process of enclosing and welding the tube blank half-blank to form the tube blank is integrated into this process, which can reduce the part processing requirements before this process, and reduce part processing time and cost.

[0012] Furthermore, in step 200: the serrations are welded onto the side of the first tube blank half-blank.

[0013] By adopting the aforementioned technical solution, the serrations are first welded to the side of the first tube blank half-blank, and then stamping and forming operations are performed. This can initially fix the position of the serrations on the tube blank half-blank, making it easier to accurately stamp and form the serrations in the subsequent process. This allows the discharge tip of the serrations to bend and the fixed part to form a bent part. It also enables better control over the contact position and state between the bent part and the inner wall of the half-tube, which is conducive to achieving the expected mechanical fitting effect.

[0014] Furthermore, in step 300: when stamping the teeth installed on the first tube blank half blank, the position where the teeth are installed on the side is stamped simultaneously, so that the position where the teeth are installed on the side is recessed to form an installation groove to accommodate the teeth, and the upper surface of the fixing part is flush with the upper surface of the side part where it is not connected to the teeth.

[0015] By employing the aforementioned technical solution, the mounting groove is simultaneously formed during the tooth stamping process, eliminating the need for additional processes and components. This avoids increased costs associated with introducing new parts and does not affect overall production efficiency, enabling the completion of multiple process objectives without additional resource and time consumption. Furthermore, the mounting groove allows the fixing portion of the tooth to be positioned within it. When the two tube blank half-pieces are joined, the movement of the tooth along the length of the tube blank is effectively restricted, enhancing the stability of the tooth on the tube blank. When the two tube blank half-pieces are joined, since the upper surface of the fixing portion is flush with the upper surface of the side portion not connected to the tooth, the second tube blank half-piece can be seamlessly joined to the first tube blank half-piece without any additional processing in subsequent steps. This technical solution also eliminates potential structural differences between the two tube blank half-pieces before entering this process, allowing them to be completely interchangeable, reducing the number of parts and further lowering production costs. The presence of the mounting groove effectively restricts the movement of the teeth along the length of the tube blank, enhancing the stability of the teeth on the tube blank.

[0016] Furthermore, a step 150 is provided between step 100 and step 200. In step 150, a plurality of mounting grooves for accommodating the teeth are stamped on the side using a stamping device. In step 200, the fixing part of the teeth 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 no mounting groove is formed.

[0017] By employing the aforementioned technical solution, pre-stamping the mounting grooves on the side allows for more precise control over the position, size, and shape of the mounting grooves. This ensures that each tooth can be accurately placed within its corresponding mounting groove, thereby improving the accuracy and consistency of tooth installation. This helps guarantee the quality stability of the RS line and reduces performance differences caused by deviations in tooth installation position. Since the mounting grooves are stamped in a separate step, their quality can be easily inspected and controlled during this process, allowing for the timely detection and correction of potential problems, such as dimensional deviations or irregular shapes, thus improving product yield.

[0018] Furthermore, in step 100, the side of the processed tube blank semi-blank is provided with a plurality of mounting grooves for accommodating the teeth; in step 200, the fixing part of the teeth is placed in the corresponding mounting groove, and the upper surface of the fixing part is flush with the upper surface of the side of the part without mounting groove.

[0019] By adopting the aforementioned technical solution, the mounting groove is set during the processing of the tube blank semi-finished part in step 100, integrating the processing of the mounting groove into the initial processing stage of the tube blank semi-finished part, further simplifying the overall production process. Compared to setting a separate step to stamp the mounting groove later, this method makes the entire manufacturing process more compact and coherent, reduces the connection time between processes, and improves production efficiency. Processing the mounting groove simultaneously with the processing of the tube blank semi-finished part eliminates the need for additional equipment and complex operations to separately stamp the mounting groove. This not only reduces processing difficulty and the equipment investment and labor costs that might result from adding processes, but also reduces the scrap rate caused by operational errors in multiple steps, thereby further reducing production costs.

[0020] Furthermore, in step 300, during the stamping process, the bent position of at least one of the discharge tips is brought close to the end of the side portion away from the half-tube portion, so that the discharge tip and the bent portion clamp the side portion from opposite sides.

[0021] By employing the aforementioned technical solution, the bent position of at least one discharge tip is pressed tightly against the side portion away from the end of the semi-tube section, and the discharge tip and the bent portion clamp the side portion from opposite sides, forming a "clamping" structure. This structure significantly increases the connection strength between the serration and the side portion of the tube blank semi-bulk, effectively preventing the serration from detaching from the side portion due to external forces during use, thus improving the overall stability and reliability of the RS line structure. This clamping form provides a redundant design for the connection between the serration and the tube blank semi-bulk, adding an extra layer of protection to the connection. Even if problems occur in the welding section, the clamping structure can still function, effectively delaying equipment failures caused by serration detachment, extending the overall service life of the electrostatic precipitator, reducing the frequency of equipment repair and replacement, and lowering maintenance costs.

[0022] An equipment for producing an RS line for an electrostatic precipitator, applicable to the aforementioned manufacturing process of an RS line for an electrostatic precipitator, includes a frame, a tube blank conveying line for conveying tube blanks and tube blanks, and a feeding device, a loading device, a second welding machine, and a pressing machine arranged sequentially along the conveying direction of the tube blank conveying line, wherein the tube blank conveying line is mounted on the frame.

[0023] It also includes a forming machine, and the feeding device and the forming machine are located on opposite sides of the same processing station on the billet conveyor line;

[0024] Alternatively, it may also include a first welding machine and a forming machine, with the feeding device and the first welding machine located on opposite sides of the same processing station on the billet conveying line, and the forming machine located downstream of the first welding machine and upstream of the feeding device.

[0025] Using the aforementioned technical solution, the above-mentioned production equipment can realize the processing of the new RS line. 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 solution above, the production equipment includes a forming machine. When the tube blank conveyor line transports the first tube blank half-blank to the feeding device position, the feeding device sequentially feeds out multiple teeth. The forming machine stamps and forms the teeth placed on the first tube blank half-blank, bending the discharge tip of the teeth and bending the fixed part of the teeth near the half-tube part to form a bent part, which abuts against the inner wall of the half-tube part; then the tube blank conveyor line transports the first tube blank half-blank to the position where the feeding device is set, and the feeding device feeds the second tube blank half-blank... The blanks are fed out, and the second tube blank half-blank is joined with the first tube blank half-blank. Then, the tube blank conveyor line transports the two tube blank half-blanks to the location of the second welding machine. The second welding machine welds the second tube blank half-blank to the first tube blank half-blank to form a tube blank, and the side of the first tube blank half-blank is covered and clamped to the side of the second tube blank half-blank. The tube blank conveyor line transports the tube blank to the location of the pressing machine, and then the pressing machine punches the end of the tube blank into a flat connecting part. The tube blank conveyor line continues to transport the completed RS line out of the above production equipment. In the second scheme described above, when the production equipment includes a first welding machine and a forming machine, the tube blank conveyor line transports the first tube blank semi-blank to the feeding device position. The feeding device then sequentially feeds out multiple protruding teeth. The first welding machine sequentially welds the multiple protruding teeth to corresponding positions on the side of the first tube blank semi-blank. The tube blank conveyor line transports the first tube blank semi-blank to the position where the forming machine is located. The forming machine stamps and forms the protruding teeth installed on the first tube blank semi-blank, bending the discharge tips of the protruding teeth and bending the fixed part of the protruding teeth near the semi-tube part to form a bent part. The bent part abuts against the inner wall of the semi-tube part. During this process, the forming machine can also simultaneously stamp the positions on the side where the protruding teeth are installed, making... The side portion where the serrated edge is installed is recessed to form an installation groove to accommodate the serrated edge. The tube blank conveyor line transports the tube blank half-blank to the location where the feeding device is set. The feeding device sends out the second tube blank half-blank and connects the second tube blank half-blank to the first tube blank half-blank. Then, the tube blank conveyor line transports the two tube blank half-blanks to the location where the second welding machine is set. The second welding machine welds the second tube blank half-blank to the first tube blank half-blank to form a tube blank, and the side portion of the first tube blank half-blank covers and clamps the fixed part with the side portion of the second tube blank half-blank. The tube blank conveyor line continues to transport the tube blank half-blanks to the location where the pressing machine is set. Then, the pressing machine punches the end of the tube blank into a flat connecting part. The tube blank conveyor line continues to transport, sending the processed RS line out of the above-mentioned production equipment.

[0026] Preferably, it also includes a stamping device, which is located upstream of the feeding device.

[0027] In the above technical solution, the tube blank conveyor line transports the first tube blank half blank to the position where the stamping equipment is set. The stamping equipment stamps several mounting grooves on the side to accommodate the teeth. Then the tube blank conveyor line transports the first tube blank half blank to the position where the feeding device is set. The feeding device feeds multiple teeth into the mounting grooves in sequence.

[0028] Furthermore, the forming machine includes a fixed frame, an upper lifting driver, an upper mold, a lower mold, and a lower lifting driver. The upper lifting driver is mounted on the fixed frame and drives the upper mold to rise and fall. The lower lifting driver is mounted 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 that accommodates the teeth. The upper mold is provided with a first extrusion block for downward extrusion of the bent part and a second extrusion block for downward extrusion of the fixed part and the side part. The lower mold is provided with a recessed groove at the position corresponding to the second extrusion block.

[0029] Using the aforementioned technical solution, the forming machine controls the lifting and lowering of the upper and lower dies respectively through upper and lower lifting drives, enabling precise control of the closing speed, pressure, and position. This allows for accurate control of the bending angle of the discharge tip and the shape and position of the bent portion formed by the bending of the fixed part during the stamping process, ensuring the consistency and precision of the tooth forming and improving the overall quality and performance of the RS line. The forming machine in the above technical solution can stamp the teeth set on the first tube blank half-bulk during stamping, bending the discharge tip of the teeth and bending the fixed part of the teeth near the half-tube section to form a bent portion, which abuts against the inner wall of the half-tube section. Simultaneously, it can also stamp the position where the teeth are installed on the side, causing the position to be recessed to form a mounting groove to accommodate the teeth.

[0030] Furthermore, the feeding device includes a stacking rack, a first ejection mechanism, a second ejection mechanism, and a guide frame. The bottom of the stacking rack is provided with a discharge port. The first ejection mechanism is located at a position corresponding to the discharge port and is used to eject the tube blank half-blanket located at the bottom of the stacking rack to the guide frame. The second ejection mechanism is located at a position corresponding to the guide frame and is used to eject the tube blank half-blanket on the guide frame to the feeding station. The tube blank transmission line is provided with a positioning block on the side away from the guide frame. The pushing directions of the first ejection mechanism and the second ejection mechanism are perpendicular.

[0031] Using the aforementioned technical solution, the stacking rack can store multiple tube blank semi-finished parts. The first ejection mechanism can sequentially eject the tube blank semi-finished parts at the bottom of the stacking rack to the guide frame, realizing automatic feeding, reducing manual operation, and improving feeding efficiency. The guide frame guides the tube blank semi-finished parts, ensuring they are accurately ejected to the feeding station. Simultaneously, a positioning block located on the side of the tube blank conveyor line away from the guide frame can precisely position the tube blank semi-finished parts, ensuring accurate positioning during subsequent processing, which is beneficial for improving processing accuracy and product quality. The pushing directions of the first and second ejection mechanisms are perpendicular. This design allows for smooth pushing of the tube blank semi-finished parts in different directions, better adapting to the transmission direction of the tube blank conveyor line and the positional requirements of the feeding station, increasing the flexibility and adaptability of the feeding device.

[0032] Furthermore, the feeding device also includes a feeding control mechanism, which includes a fixed block, a moving block, a fixed rack, a sliding rack, a first spring, a second spring, and a limiting gear. The limiting gear is rotatably connected to the stacking rack, and one tooth of the limiting gear supports a tube blank half-blanket located inside the stacking rack. The fixed block is fixed to the stacking rack. The fixed rack and the sliding rack are arranged side by side on the moving block. 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 located 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 for engaging the fixed rack with the limiting gear and an unlocking position for engaging the sliding rack with the limiting gear. The first spring is located 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 one tooth pitch. When the telescopic rod of the first ejection mechanism retracts, the telescopic rod abuts against and moves the moving block to the unlocking position.

[0033] Using the aforementioned technical solution, one tooth of the limiting gear supports a half-bulb. Only when the sliding rack switches positions and meshes with the limiting gear will a half-bulb be released, effectively avoiding over-feeding or inaccurate feeding, and ensuring the accuracy and stability of the feeding process. The automatic triggering of feeding is achieved by utilizing the design of the telescopic rod of the first ejection mechanism retracting to press against and move the moving block to the unlocked position. No additional control system or manual intervention is required, making the entire feeding process more automated and smooth, reducing the workload and error probability of manual operation, and improving production efficiency.

[0052] The technical solutions of this application will be described in detail below with specific embodiments. The following specific embodiments can be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0053] like Figures 12 to 13 As shown, an RS wire for an electrostatic precipitator includes two tube blanks 1.1 and several teeth 1.2. Each tube 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 two tube blanks 1.1 are stacked and welded to form a tube blank 1.3. The tube blank 1.3 includes a tube blank body 1.3.0, connecting portions 1.3.1 located at both ends of the tube blank body 1.3.0, and connecting portions 1.3.1 located on opposite sides of the tube blank body 1.3.0. The tube blank side 1.3.2 is formed by welding together the side portions 1.1.2 of two tube blank half blanks 1.1. A plurality of teeth 1.2 are spaced apart on the tube blank side 1.3.2. Each tooth 1.2 includes a fixing part 1.2.1 and a discharge part 1.2.2. The side portions 1.1.2 of the two tube blank half blanks 1.1 cover the fixing part 1.2.1. The discharge part 1.2.2 is provided with a discharge tip 1.2.3.

[0054] Example 1:

[0055] like Figure 1 As shown, this application provides a manufacturing process for an RS wire in an electrostatic precipitator, including the following steps:

[0056] Step 100: Use metal parts to process a tube blank half blank 1.1 and a tooth 1.2. The tube blank 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 with a discharge tip 1.2.3.

[0057] Step 200: The tooth 1.2 is conveyed to the corresponding position on the side 1.1.2 of the first tube blank half blank 1.1;

[0058] Step 300: The tooth 1.2 set on the first tube blank half blank 1.1 is stamped and formed, so that the discharge tip 1.2.3 of the tooth 1.2 is bent, and the fixing part 1.2.1 of the tooth 1.2 is bent at one end near the half 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 half tube part 1.1.1;

[0059] Step 400: After sequentially completing the conveying and stamping of multiple teeth 1.2, the second tube blank half-blank 1.1 is joined with the first tube blank half-blank 1.1, and their side parts 1.1.2 are welded together to form a tube blank 1.3. The side parts 1.1.2 of the first tube blank half-blank 1.1 and the side parts 1.1.2 of the second tube blank half-blank 1.1 cover the fixing part 1.2.1.

[0060] Step 500: The end of the tube blank 1.3 is stamped into a flat connecting part 1.3.1 by the press head machine 6.

[0061] The aforementioned manufacturing process for the RS line 1 electrostatic precipitator achieves a dual improvement in product reliability and production efficiency through structural optimization and process integration. Its core innovations are: 1) The use of a double-sided tube blank half-blade 1.1 with side portions 1.1.2 completely enclosing the fixing portion 1.2.1 of the tooth 1.2 between the two side portions 1.1.2, forming a physical isolation barrier. This effectively blocks direct contact between corrosive media in the operating environment and the fixing portion 1.2.1, significantly reducing the risk of tooth 1.2 detachment; 2) The bending portion 1.2.4 forms a mechanical fit with the inner wall of the half-tube portion 1.1.1. This structure can still provide reliable pull-out resistance even when the connection between the fixing portion 1.2.1 and the side portion 1.1.2 fails; 3) In stamping… In the forming process, synchronous and collaborative processing is implemented. While completing the bending of the discharge tip 1.2.3, the bent part 1.2.4 and the inner wall of the half tube part 1.1.1 are mechanically fitted together. The two processing operations are combined into one operation, which can improve the overall processing efficiency. This can be achieved through mold structure optimization design, which reduces the equipment modification cost and does not affect the production cycle time. 4) By optimizing the process layout, the process of welding the tube blank half blank 1.1 to form the tube blank 1.3, which originally required a pre-processing step, is integrated into this process. This can reduce the part processing requirements before this process and reduce the part processing time and cost.

[0062] Preferably, in step 100: the tube blank semi-blank 1.1 is processed from a metal sheet by a stamping process, and the tooth 1.2 is processed from a metal sheet by a punching process.

[0063] Example 2:

[0064] like Figure 2 As shown, a manufacturing process for an RS wire in an electrostatic precipitator includes the following steps:

[0065] Step 100: The tube blank half-blank 1.1 and the tooth 1.2 are processed by metal sheet stamping and blanking process. The tube blank half-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 tooth 1.2 includes a fixing part 1.2.1 and a discharge part 1.2.2 with a discharge tip 1.2.3.

[0066] Step 200: Convey and weld the tooth 1.2 to the corresponding position on the side 1.1.2 of the first tube blank half blank 1.1;

[0067] Step 300: The tooth 1.2 set on the first tube blank half-blank 1.1 is stamped, so that the discharge tip 1.2.3 of the tooth 1.2 is bent, and the fixing part 1.2.1 of the tooth 1.2 is bent at the end near the half 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 half tube part 1.1.1. At the same time, the position where the tooth 1.2 is installed on the side part 1.1.2 is stamped, so that the position where the tooth 1.2 is installed on the side part 1.1.2 is recessed to form a mounting groove 1.1.3 to accommodate the tooth 1.2. The upper surface of the fixing part 1.2.1 is flush with the upper surface of the side part 1.1.2 at the position not connected to the tooth 1.2. At least one of the bent positions of the discharge tip 1.2.3 is close to the end of the side part 1.1.2 away from the half tube part 1.1.1. Figure 14 As shown, the discharge tip 1.2.3 and the bent portion 1.2.4 are clamped together from opposite sides to the side portion 1.1.2;

[0068] Step 400: After sequentially completing the conveying and stamping of multiple teeth 1.2, the second tube blank half-blank 1.1 is joined with the first tube blank half-blank 1.1, and their side parts 1.1.2 are welded together to form a tube blank 1.3. The side parts 1.1.2 of the first tube blank half-blank 1.1 and the side parts 1.1.2 of the second tube blank half-blank 1.1 cover the fixing part 1.2.1.

[0069] Step 500: The end of the tube blank 1.3 is stamped into a flat connecting part 1.3.1 by the press head machine 6;

[0070] Step 600: Machine the connecting hole in the connecting part by punching or drilling.

[0071] By adopting the aforementioned technical solution, the teeth 1.2 are first welded onto the side portion 1.1.2 of the first tube blank half-bulk 1.1, followed by stamping and other operations. This allows the position of the teeth 1.2 on the tube blank half-bulk 1.1 to be initially fixed, facilitating subsequent accurate stamping of the teeth 1.2. This causes the discharge tip 1.2.3 of the teeth 1.2 to bend and the fixing portion 1.2.1 to form a bent portion 1.2.4. Furthermore, it allows for better control of the contact position and state between the bent portion 1.2.4 and the inner wall of the half-tube portion 1.1.1, which is beneficial for achieving the desired mechanical fitting effect. By simultaneously forming the mounting groove 1.1.3 through the stamping of the teeth 1.2, no new processes or additional components are required, avoiding the increased costs associated with introducing new components. Simultaneously, it does not affect overall production efficiency, achieving multiple process objectives without consuming additional resources and time. Meanwhile, the mounting groove 1.1.3 allows the fixing part 1.2.1 of the tooth 1.2 to be positioned within the mounting groove 1.1.3. When the two tube blank half-pieces 1.1 are joined together, the movement of the tooth 1.2 along the length of the tube blank 1.3 is effectively restricted, enhancing the stability of the tooth 1.2 on the tube blank 1.3. When the two tube blank half-pieces 1.1 are joined, since the upper surface of the fixing part 1.2.1 is flush with the upper surface of the side part 1.1.2 at the position not connected to the tooth 1.2, the second tube blank half-piece 1.1 can be seamlessly joined to the first tube blank half-piece 1.1 without any additional processing in subsequent processes. The above technical solution also eliminates potential structural differences between the two tube blank half-pieces 1.1 before entering this process, allowing them to be completely interchangeable, reducing the number of parts and further lowering production costs. The presence of the mounting groove 1.1.3 effectively restricts the movement of the tooth 1.2 along the length of the tube blank 1.3, thereby enhancing the stability of the tooth 1.2 on the tube blank 1.3.

[0072] Example 3:

[0073] like Figure 3 As shown: A manufacturing process for an RS wire in an electrostatic precipitator includes the following steps:

[0074] Step 100: The tube blank half-blank 1.1 and the tooth 1.2 are processed by metal sheet stamping and blanking process. The tube blank half-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 tooth 1.2 includes a fixing part 1.2.1 and a discharge part 1.2.2 with a discharge tip 1.2.3.

[0075] Step 150: Several mounting slots 1.1.3 for accommodating the teeth 1.2 are stamped on the side 1.1.2 using the stamping equipment 10;

[0076] Step 200: The tooth 1.2 is conveyed to the side part 1.1.2 of the first tube blank half blank 1.1, so that the fixing part 1.2.1 of the tooth 1.2 is placed in the corresponding mounting groove 1.1.3, and the upper surface of the fixing part 1.2.1 is flush with the upper surface of the side part 1.1.2 where the mounting groove 1.1.3 is not formed;

[0077] Step 300: After the multiple teeth 1.2 are conveyed and stamped in sequence, the teeth 1.2 installed on the first tube blank half blank 1.1 are stamped and formed, so that the discharge tip 1.2.3 of the teeth 1.2 is bent, and the fixed part 1.2.1 of the teeth 1.2 is bent at the end near the half 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 half tube part 1.1.1;

[0078] Step 400: Connect the second tube blank half-blank 1.1 to the first tube blank half-blank 1.1, and weld their side portions 1.1.2 to form tube blank 1.3. The side portions 1.1.2 of the first tube blank half-blank 1.1 and the side portions 1.1.2 of the second tube blank half-blank 1.1 cover the fixing portion 1.2.1.

[0079] Step 500: The end of the tube blank 1.3 is stamped into a flat connecting part by the press head machine 6;

[0080] Step 600: Machine the connecting hole in the connecting part by punching or drilling.

[0081] By employing the aforementioned technical solution, pre-stamping the mounting groove 1.1.3 on the side 1.1.2 allows for more precise control over the position, size, and shape of the mounting groove 1.1.3, ensuring that each tooth 1.2 can be accurately placed within its corresponding mounting groove 1.1.3, thereby improving the accuracy and consistency of tooth 1.2 installation. This helps guarantee the quality stability of the RS line and reduces performance differences caused by deviations in the tooth 1.2 installation position. Since the mounting groove 1.1.3 is stamped in a separate step, its quality can be easily inspected and controlled during this step, allowing for timely detection and correction of potential problems, such as dimensional deviations or irregular shapes, thus improving product yield.

[0082] Preferably, in step 300, during the stamping process, at least one of the bent positions of the discharge tip 1.2.3 is brought close to 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.

[0083] By employing the aforementioned technical solution, the bent position of at least one discharge tip 1.2.3 is positioned close to the end of the side portion 1.1.2 away from the half-tube portion 1.1.1, and 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 "clamping". This structure significantly increases the connection strength between the tooth 1.2 and the side portion 1.1.2 of the tube blank half-bulk 1.1, effectively preventing the tooth 1.2 from falling off from the side portion 1.1.2 due to external forces during use, thus improving the stability and reliability of the overall RS line structure. This clamping form provides a redundant design for the connection between the tooth 1.2 and the tube blank half-bulk 1.1, adding an extra layer of protection to the connection. Even if problems occur in the welding section, the clamping structure can still function, effectively delaying equipment failures caused by the tooth 1.2 falling off, extending the overall service life of the electrostatic precipitator, reducing the frequency of equipment repair and replacement, and lowering maintenance costs.

[0084] Example 4:

[0085] like Figure 4 As shown: A manufacturing process for an RS wire in an electrostatic precipitator includes the following steps:

[0086] Step 100: The tube blank half-blank 1.1 and the tooth 1.2 are processed by metal sheet stamping and blanking process. The tube blank half-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 tube blank half-blank 1.1 is divided into a first tube blank half-blank 1.1 and a second tube blank half-blank 1.1. The side part 1.1.2 of the first tube blank half-blank 1.1 is provided with a plurality of mounting grooves 1.1.3 for accommodating the tooth 1.2. The tooth 1.2 includes a fixing part 1.2.1 and a discharge part 1.2.2 with a discharge tip 1.2.3.

[0087] Step 200: The tooth 1.2 is conveyed to the side part 1.1.2 of the first tube blank half blank 1.1, so that the fixing part 1.2.1 of the tooth 1.2 is placed in the corresponding mounting groove 1.1.3, and the upper surface of the fixing part 1.2.1 is flush with the upper surface of the side part 1.1.2 where the mounting groove 1.1.3 is not formed;

[0088] Step 300: After the multiple teeth 1.2 are conveyed and stamped in sequence, the teeth 1.2 installed on the first tube blank half blank 1.1 are stamped and formed, so that the discharge tip 1.2.3 of the teeth 1.2 is bent, and the fixed part 1.2.1 of the teeth 1.2 is bent at the end near the half 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 half tube part 1.1.1;

[0089] Step 400: Connect the second tube blank half-blank 1.1 to the first tube blank half-blank 1.1, and weld their side portions 1.1.2 to form tube blank 1.3. The side portions 1.1.2 of the first tube blank half-blank 1.1 and the side portions 1.1.2 of the second tube blank half-blank 1.1 cover the fixing portion 1.2.1.

[0090] Step 500: The end of the tube blank 1.3 is stamped into a flat connecting part by the press head machine 6;

[0091] Step 600: Machine the connecting hole in the connecting part by punching or drilling.

[0092] By adopting the aforementioned technical solution, the mounting groove 1.1.3 is set during the processing of the tube blank semi-finished part 1.1 in step 100, integrating the processing of the mounting groove 1.1.3 into the initial processing stage of the tube blank semi-finished part 1.1, further simplifying the overall production process. Compared to setting a separate step to stamp the mounting groove 1.1.3 later, 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 mounting groove 1.1.3 is carried out simultaneously with the processing of the tube blank semi-finished part 1.1, eliminating the need for additional equipment and complex operations to separately stamp the mounting groove 1.1.3. This not only reduces processing difficulty and the equipment investment and labor costs that may result from adding processes, but also reduces the scrap rate caused by operational errors in multiple steps, thereby further reducing production costs.

[0093] Preferably, in step 300, during the stamping process, at least one of the bent positions of the discharge tip 1.2.3 is brought close to 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.

[0094] By employing the aforementioned technical solution, the bent position of at least one discharge tip 1.2.3 is positioned close to the end of the side portion 1.1.2 away from the half-tube portion 1.1.1, and 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 "clamping". This structure significantly increases the connection strength between the tooth 1.2 and the side portion 1.1.2 of the tube blank half-bulk 1.1, effectively preventing the tooth 1.2 from falling off from the side portion 1.1.2 due to external forces during use, thus improving the stability and reliability of the overall RS line structure. This clamping form provides a redundant design for the connection between the tooth 1.2 and the tube blank half-bulk 1.1, adding an extra layer of protection to the connection. Even if problems occur in the welding section, the clamping structure can still function, effectively delaying equipment failures caused by the tooth 1.2 falling off, extending the overall service life of the electrostatic precipitator, reducing the frequency of equipment repair and replacement, and lowering maintenance costs.

[0095] Example 5:

[0096] like Figure 5 As shown, a manufacturing process for an RS wire in an electrostatic precipitator includes the following steps:

[0097] Step 100: The tube blank half-blank 1.1 and the tooth 1.2 are processed by metal sheet stamping and blanking process. The tube blank half-blank 1.1 includes a half tube part 1.1.1, side parts 1.1.2 located on opposite sides of the half 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 tooth 1.2. The tooth 1.2 includes a fixing part 1.2.1 and a discharge part 1.2.2 with a discharge tip 1.2.3. The depth of the mounting groove 1.1.3 is equal to half the thickness of the fixing part 1.2.1.

[0098] Step 200: The tooth 1.2 is conveyed and welded to the side part 1.1.2 of the first tube blank half blank 1.1, so that the fixing part 1.2.1 of the tooth 1.2 is placed in the corresponding mounting groove 1.1.3;

[0099] Step 300: The tooth 1.2 mounted on the first tube blank half-bulk 1.1 is stamped, causing the discharge tip 1.2.3 of the tooth 1.2 to bend, and the fixing part 1.2.1 of the tooth 1.2 is bent at one end near the half-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 half-tube part 1.1.1, so that at least one of the bent positions of the discharge tip 1.2.3 is close to the end of the side part 1.1.2 away from the half-tube part 1.1.1, such as... Figure 2 As shown, the discharge tip 1.2.3 and the bent portion 1.2.4 are clamped together from opposite sides to the side portion 1.1.2;

[0100] Step 400: Connect the second tube blank half-blank 1.1 with the first tube blank half-blank 1.1, aligning the mounting groove 1.1.3 on the second tube blank half-blank 1.1 with the fixing part 1.2.1 of the corresponding tooth 1.2, and weld the side parts 1.1.2 of the two to form tube blank 1.3. The side parts 1.1.2 of the first tube blank half-blank 1.1 and the side parts 1.1.2 of the second tube blank half-blank 1.1 cover the fixing part 1.2.1.

[0101] Step 500: The end of the tube blank 1.3 is stamped into a flat connecting part by the press head machine 6;

[0102] Step 600: Machine the connecting hole in the connecting part by punching or drilling.

[0103] Preferably, in step 300, during the stamping process, at least one of the bent positions of the discharge tip 1.2.3 is brought close to 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.

[0104] By employing the aforementioned technical solution, the bent position of at least one discharge tip 1.2.3 is positioned close to the end of the side portion 1.1.2 away from the half-tube portion 1.1.1, and 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 "clamping". This structure significantly increases the connection strength between the tooth 1.2 and the side portion 1.1.2 of the tube blank half-bulk 1.1, effectively preventing the tooth 1.2 from falling off from the side portion 1.1.2 due to external forces during use, thus improving the stability and reliability of the overall RS line structure. This clamping form provides a redundant design for the connection between the tooth 1.2 and the tube blank half-bulk 1.1, adding an extra layer of protection to the connection. Even if problems occur in the welding section, the clamping structure can still function, effectively delaying equipment failures caused by the tooth 1.2 falling off, extending the overall service life of the electrostatic precipitator, reducing the frequency of equipment repair and replacement, and lowering maintenance costs.

[0105] Example 6:

[0106] like Figure 2 and Figure 5 As shown, an electrostatic precipitator RS line production equipment, applicable to the aforementioned electrostatic precipitator RS line manufacturing process, includes a frame 2, a tube blank transport line 3 for transporting tube blank semi-blanks 1.1 and tube blanks 1.3, and a feeding device 4, a loading device 7, a second welding machine 11, and a pressing machine 6 arranged sequentially along the transport direction of the tube blank transport line 3. The tube blank transport line 3 is mounted on the frame 2; it also includes a first welding machine 5 and a pressing machine 6. Figure 11 The forming machine 9, the feeding device 4 and the first welding machine 5 shown are located on opposite sides of the same processing station of the billet transmission line 3. The forming machine 9 is located downstream of the first welding machine 5 and upstream of the feeding device 7.

[0107] Using the aforementioned technical solution, the above-mentioned production equipment can realize the processing of the new RS line 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 first solution mentioned above, the production equipment includes a forming machine 9. When the tube blank conveyor line 3 conveys the first tube blank half blank 1.1 to the feeding device 4, the feeding device 4 sequentially feeds out multiple teeth 1.2. The forming machine 9 stamps and forms the teeth 1.2 placed on the first tube blank half blank 1.1, bending the discharge tip 1.2.3 of the teeth 1.2 and bending the fixed part 1.2.1 of the teeth 1.2 near the end of the half 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 half tube part 1.1.1. Then the tube blank conveyor line 3 conveys the first tube blank half blank 1.1 to the position where the feeding device 7 is set. The feeding device 7 feeds the second tube blank half blank Part 1.1 is sent out, and the second tube blank half-blank part 1.1 is joined with the first tube blank half-blank part 1.1. Then, the tube blank conveyor line 3 conveys the two tube blank half-blank 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 half-blank part 1.1 to the first tube blank half-blank part 1.1 to form tube blank part 1.3, and makes the side part 1.1.2 of the first tube blank half-blank part 1.1 and the side part 1.1.2 of the second tube blank half-blank part 1.1 cover and clamp the fixing part 1.2.1. The tube blank conveyor line 3 conveys the tube blank part 1.3 to the position where the pressing machine 6 is set, and then the pressing machine 6 punches the end of the tube blank part 1.3 into a flat connecting part 1.3.1. The tube blank conveyor line 3 continues to convey, and sends the processed RS line 1 out of the above-mentioned production equipment.In the second scheme described above, when the production equipment includes a first welding machine 5 and a forming machine 9, when the tube blank conveyor line 3 transports the first tube blank semi-blank 1.1 to the feeding device 4, the feeding device 4 sequentially feeds out multiple teeth 1.2. The first welding machine 55 sequentially welds the multiple teeth 1.2 to the corresponding positions of the side portions 1.1.2 of the first tube blank semi-blank 1.1. The tube blank conveyor line 3 transports the first tube blank semi-blank 1.1 to the position where the forming machine 9 is located. 9. The teeth 1.2 installed on the first tube blank half-bulk 1.1 are stamped, causing the discharge tip 1.2.3 of the teeth 1.2 to bend, and the fixing part 1.2.1 of the teeth 1.2 near the half-tube part 1.1.1 to be bent to form a bent part 1.2.4, which abuts against the inner wall of the half-tube part 1.1.1. During this process, the forming machine 9 can also simultaneously stamp the position on the side part 1.1.2 where the teeth 1.2 are installed, so that the side part 1.1.2 is stamped. The edge 1.1.2 is recessed at the position where the tooth 1.2 is installed to form an installation groove 1.1.3 to accommodate the tooth 1.2; the tube blank conveyor line 3 transports the tube blank half-blank 1.1 to the position where the feeding device 7 is set, the feeding device 7 sends out the second tube blank half-blank 1.1 and connects the second tube blank half-blank 1.1 with the first tube blank half-blank 1.1, and then the tube blank conveyor line 3 transports the two tube blank half-blanks 1.1 to the position where the second welding machine 11 is set, the second welding machine 11 will... The second tube blank half-bulk 1.1 is welded and fixed to the first tube blank half-bulk 1.1 to form tube blank 1.3, and the side portion 1.1.2 of the first tube blank half-bulk 1.1 and the side portion 1.1.2 of the second tube blank half-bulk 1.1 cover and clamp the fixing part 1.2.1; the tube blank conveyor line 3 continues to convey the tube blank half-bulk 1.1 to the position where the pressing machine 6 is set, and then the end of the tube blank 1.3 is stamped into a flat connecting part 1.3.1 by the pressing machine 6. The tube blank conveyor line 3 continues to convey and send the processed RS line 1 out of the above-mentioned production equipment.

[0108] In another embodiment, it also includes a stamping device 10, which is located upstream of the feeding device 4.

[0109] In the above technical solution, the tube blank conveying line 3 transports the first tube blank half blank 1.1 to the position where the stamping equipment 10 is set. The stamping equipment 10 stamps several mounting grooves 1.1.3 for accommodating the teeth 1.2 on the side 1.1.2. Then, the tube blank conveying line 3 transports the first tube blank half blank 1.1 to the position where the feeding device 4 is set. The feeding device 4 feeds multiple teeth 1.2 sequentially into the mounting grooves 1.1.3.

[0110] Preferably, in order to increase welding efficiency, a second welding machine 11 can be set on each of the opposite sides of the tube blank transmission line 3 to weld the side portions 1.1.2 on both sides respectively.

[0111] Example 7:

[0112] like Figure 1 , Figure 3 and Figure 4 As shown: A production equipment for an electrostatic precipitator RS line 1, applicable to the aforementioned electrostatic precipitator RS line manufacturing process, includes a frame 2, a tube blank transport line 3 for transporting tube blank semi-blanks 1.1 and tube blanks 1.3, and a feeding device 4, a loading device 7, a second welding machine 11, and a pressing machine 6 arranged sequentially along the transport direction of the tube blank transport line 3. The tube blank transport line 3 is mounted on the frame 2; it also includes, as shown in the image. Figure 11 The forming machine 9 shown is located on opposite sides of the same processing station of the billet conveyor line 3. The feeding device 4 and the forming machine 9 are located on opposite sides of the same processing station.

[0113] The aforementioned production equipment can process the new RS line 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. When the tube blank transport line 3 transports the first tube blank half-blank 1.1 to the feeding device 4, the feeding device 4 sequentially feeds out multiple teeth 1.2. The forming machine 9 stamps and forms the teeth 1.2 placed on the first tube blank half-blank 1.1, bending the discharge tip 1.2.3 of the teeth 1.2 and bending the fixed part 1.2.1 of the teeth 1.2 near the end of the half-tube part 1.1.1 to form a bent part 1.2.4, which abuts against the inner wall of the half-tube part 1.1.1. Then, the tube blank transport line 3 transports the first tube blank half-blank 1.1 to the position where the feeding device 7 is set, and the feeding device 7 feeds out the second tube blank half-blank 1.1. The second tube blank half-bulk 1.1 is then joined with the first tube blank half-bulk 1.1. The tube blank transport line 3 then conveys the two tube blank half-bulks 1.1 to the location of the second welding machine 11. The second welding machine 11 welds the second tube blank half-bulk 1.1 to the first tube blank half-bulk 1.1 to form a tube blank 1.3. The side portion 1.1.2 of the first tube blank half-bulk 1.1 is then covered and clamped to the fixing portion 1.2.1 by the side portion 1.1.2 of the second tube blank half-bulk 1.1. The tube blank transport line 3 conveys the tube blank 1.3 to the location of the pressing machine 6, where the end of the tube blank 1.3 is stamped into a flat connecting portion. The tube blank transport line 3 continues to convey the finished RS line 1 out of the production equipment.

[0114] In another embodiment, it is understood that the process also includes a stamping device 10, which is located upstream of the feeding device 4.

[0115] In the above technical solution, the billet conveyor line 3 transports the first billet half-piece 1.1 to the location where the stamping equipment 10 is set. The stamping equipment 10 stamps several mounting grooves 1.1.3 on the side 1.1.2 to accommodate the teeth 1.2. Then, the billet conveyor line 3 transports the first billet half-piece 1.1 to the location where the feeding device 4 is set. The feeding device 4 feeds the multiple teeth 1.2 sequentially into the mounting grooves 1.1.3. When the forming machine 9 stamps the teeth 1.2, it is not necessary to stamp again to generate the mounting grooves 1.1.3.

[0116] Example 8:

[0117] Based on Example 6 or Example 7, such as Figure 11 The forming machine 9 shown includes a fixed frame 9.1, an upper lifting driver 9.2, an upper mold 9.3, a lower mold 9.4, and a lower lifting driver 9.5. The upper lifting driver 9.2 is mounted on the fixed frame 9.1 and drives the upper mold 9.3 to rise and fall. The lower lifting driver 9.5 is mounted on the fixed frame 9.1 and drives the lower mold 9.4 to rise and fall. After the upper mold 9.3 and the lower mold 9.4 are closed, they form a forming cavity to accommodate the tooth 1.2. The upper mold 9.3 is provided with a first extrusion block 9.3.1 for downward extrusion of the bent part 1.2.4 and a second extrusion block 9.3.2 for downward extrusion of the fixed part 1.2.1 and the side part 1.1.2. The lower mold 9.4 is provided with a recessed groove at the position corresponding to the second extrusion block 9.3.2.

[0118] By adopting the aforementioned 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, which enables precise control of the closing speed, pressure, and position. This allows for accurate control of the bending angle of the discharge tip 1.2.3 and the shape and position of the bent part 1.2.4 formed by the bending of the fixed part 1.2.1 during the stamping process, ensuring the consistency and precision of the forming of the tooth 1.2, and improving the overall quality and performance of the RS line. In the above technical solution, the forming machine 9 can stamp the teeth 1.2 set on the first tube blank half blank 1.1 during stamping, so that the discharge tip 1.2.3 of the teeth 1.2 is bent, and the fixing part 1.2.1 of the teeth 1.2 is bent at the end near the half 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 half tube part 1.1.1. Simultaneously, the position where the teeth 1.2 are installed on the side part 1.1.2 can be stamped, so that the position where the teeth 1.2 are installed on the side part 1.1.2 is recessed to form a mounting groove 1.1.3 to accommodate the teeth 1.2.

[0119] Preferred, such as Figures 1 to 5As shown, the feeding device 7 includes a stacking rack 7.1, a first ejection mechanism 7.2, a second ejection mechanism 7.3, and a guide frame 7.4. The bottom of the stacking rack 7.1 is provided with a discharge port 7.5. The first ejection mechanism 7.2 is located at a position corresponding to the discharge port 7.5 and is used to eject the tube blank half-blank 1.1 located at the bottom of the stacking rack 7.1 to the guide frame 7.4. The second ejection mechanism 7.3 is located at a position corresponding to the guide frame 7.4 and is used to eject the tube blank half-blank 1.1 on the guide frame 7.4 to the feeding station. The tube blank transmission line 3 is provided with a positioning block 7.6 on the side away from the guide frame 7.4. The pushing directions of the first ejection mechanism 7.2 and the second ejection mechanism 7.3 are perpendicular.

[0120] Using the aforementioned technical solution, the stacking rack 7.1 can store multiple tube blank semi-finished parts 1.1. The first ejection mechanism 7.2 can sequentially eject the tube blank semi-finished parts 1.1 at the bottom of the stacking rack 7.1 to the guide frame 7.4, realizing automatic feeding, reducing manual operation, and improving feeding efficiency. The guide frame 7.4 guides the tube blank semi-finished parts 1.1, ensuring they are accurately ejected to the feeding station. Simultaneously, the positioning block 7.6 on the side of the tube blank conveyor line 3 opposite to the guide frame 7.4 can precisely position the tube blank semi-finished parts 1.1, ensuring accurate positioning in subsequent processing, which is beneficial for improving processing accuracy and product quality. The pushing directions of the first ejection mechanism 7.2 and the second ejection mechanism 7.3 are perpendicular. This design allows the tube blank semi-finished parts 1.1 to be smoothly pushed in different directions, better adapting to the transmission direction of the tube blank conveyor line 3 and the position requirements of the feeding station, increasing the flexibility and adaptability of the feeding device 7.

[0121] Understandably, a feeding device 7 can also be set upstream of the feeding device 4 to provide the first tube blank half-blank 1.1 for the tube blank transfer line 3. The opening of the half-tube portion 1.1.1 of the tube blank half-blank 1.1 in the feeding device 7 upstream of the feeding device 4 faces upward, while the opening of the half-tube portion 1.1.1 of the tube blank half-blank 1.1 in the feeding device 7 downstream of the feeding device 4 faces downward.

[0122] Specifically, the tube blank half blanks 1.1 in the stacking rack 7.1 are stacked vertically. Since the outer tube diameter of the half tube 1.1.1 is larger than the inner tube diameter, gaps will appear in the vertical direction when the tube blank half blanks 1.1 are stacked vertically.

[0123] In one embodiment based on Example 8, the feeding device 7 further includes a discharging control mechanism 8. The discharging control mechanism 8 drives a limiting gear 8.7 to rotate via a motor. The tooth pitch of the limiting gear 8.7 matches the vertical gap when the tube blank half-blanks 1.1 are stacked vertically, so that the tube blank half-blank 1.1 being pushed out does not contact the tube blank half-blank 1.1 above it, thus avoiding the tube blank half-blank 1.1 being scratched by the tube blank half-blank 1.1 above it during dragging, and also avoiding the situation where it is pressed down by the tube blank half-blank 1.1 above it and difficult to push out.

[0124] In another embodiment based on Example 8, such as Figures 6 to 10 As shown, the feeding device 7 also includes a discharging control mechanism 8. The discharging control mechanism 8 includes a fixed block 8.1, a sliding groove 8.0 disposed 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 limiting gear 8.7. The limiting gear 8.7 is rotatably connected to the stacking rack 7.1, and one of the teeth of the limiting gear 8.7 supports a tube blank half-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, and the sliding rack 8.4 is slidably connected to the moving block 8.2 and has a first position. In the first position, a second spring 8.6 is located 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 groove 8.0 in the fixed block 8.1 and has a locking position for engaging the fixed rack 8.3 with the limiting gear 8.7 and an unlocking position for engaging the sliding rack 8.4 with the limiting gear 8.7. A first spring 8.5 is located between the fixed block 8.1 and the moving block 8.2 to keep the moving block 8.2 in the locked 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 push-out mechanism 7.2 retracts, the telescopic rod abuts and moves the moving block 8.2 to the unlocking position.

[0125] The specific steps of adopting the aforementioned technical solution are as follows: When the telescopic rod of the first ejection mechanism 7.2 retracts after completing the ejection action, as... Figures 7 to 8 As shown, it will press against and pull the moving block 8.2 to the unlocked position (limit gear 8.7 and sliding rack 8.4 are engaged). At this time, the first spring 8.5 will be in a stretched state. Due to the pressure of the weight of the tube blank half-bulk 1.1, the sliding rack 8.4 rotates one tooth's stroke, causing the sliding rack 8.4 to move downwards by one tooth's distance and touch the bottom wall of the sliding groove where the sliding rack 8.4 is located, which is the second position of the sliding rack 8.4 (as shown). Figure 9 and Figure 10As shown in the diagram, simultaneously, the second spring 8.6 is compressed. At this point, the bottommost tube blank half-bulk 1.1, after losing the limit of the limiting gear 8.7, falls to the discharge port 7.5, completing the unloading action. Then, as... Figures 9 to 10 As shown, the first spring 8.5 pulls the moving block 8.2 to the locked position (the limit gear 8.7 and the fixed rack 8.3 are engaged). At this time, the second spring 8.6 extends and pushes the moving rack 8.4 back to the initial first position (as shown). Figure 7 and Figure 8 (As shown).

[0126] One tooth of the limiting gear 8.7 supports the tube blank half-piece 1.1. Only when the sliding rack 8.4 switches positions and meshes with the limiting gear 8.7 will one tube blank half-piece 1.1 be released, effectively avoiding over-feeding or inaccurate feeding, and ensuring the accuracy and stability of feeding. The automatic triggering of feeding is achieved by utilizing the design of the telescopic rod of the first ejection mechanism 7.2 retracting to press against and move the moving block 8.2 to the unlocked position. No additional control system or manual intervention is required, making the entire feeding process more automated and smooth, reducing the workload and error probability of manual operation, improving production efficiency, and providing greater stability when controlling the drop of the tube blank half-piece 1.1. It can accurately trigger the rotation of the limiting gear 8.7 after the telescopic rod retracts, causing the corresponding tube blank half-piece 1.1 to drop to the designated position.

[0127] Preferably, there are two feeding control mechanisms 8, which are located on opposite sides of the feeding device 7. Each feeding control mechanism 8 also includes at least one second gear, which is rotatably connected to the stacking rack 7.1. The second gear and the limiting gear 8.7 are spaced apart along the extension and retraction direction of the telescopic rod, and the second gear and the limiting gear 8.7 are coaxially fixed by a coupling 8.8.

[0128] The steps in the above flowchart are aligned end to end. There is a gap between the upstream and downstream frames 2 of the press head machine 6, the first welding machine 5, and the second welding machine 11, so that the press head machine 6, the first welding machine 5, and the second welding machine 11 can work. The above-mentioned conveying device that conveys the tooth 1.2 onto the tube blank will lower its conveying end after the tooth 1.2 is conveyed to the designated position to avoid the tooth 1.2 moving along the conveying line.

[0129] In addition to the preferred embodiments described above, this application has other implementation methods. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection claimed in this application.
