Description

Technical Field

[0001] This invention relates to the field of channel processing technology, specifically to a method and production line for manufacturing pre-embedded channels. Background Technology

[0002] In subway construction, the subway pre-embedded channel is a key component used to fix and support various equipment and pipelines. It is usually pre-embedded in the concrete structure to provide a reliable connection foundation for subsequent equipment installation.

[0003] The pre-embedded channel structure of the subway mainly consists of the channel body and anchor bolts. Currently, the connection between the channel body and anchor bolts is generally achieved through hot forging. The channel body has mounting holes corresponding to the anchor bolt installation positions, and the anchor bolts are connected to the corresponding mounting holes in the channel body with inserts. During assembly, the inserts on the anchor bolts are heated to a suitable temperature. Workers then remove the anchor bolt shaft and insert the insert into the mounting hole in the channel body. External equipment holds one end of the anchor bolt while another device presses the insert, transforming it from a columnar shape into a disc shape, thus completing the connection between the anchor bolt and the channel body.

[0004] However, this method has many drawbacks. Firstly, the hot forging process requires heating the metal to a high temperature, which not only consumes a large amount of energy, increasing energy costs in the production process, but also may adversely affect the properties of the metal material, such as causing a decrease in mechanical properties and uneven microstructure, thus affecting the overall structural strength and stability of the embedded channel. Secondly, the hot forging process is relatively complex, requiring high technical skills from both equipment and operators, resulting in relatively low production efficiency and increased production cycle and cost. Furthermore, the joints formed by hot forging may loosen or deform during long-term use due to vibrations and loads from subway operation, reducing the reliability and safety of the embedded channel and increasing the difficulty and cost of later maintenance and repair. In addition, this operation is currently mostly performed manually, which carries certain risks. Summary of the Invention

[0097] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0098] This application provides the following technical solution:

[0099] A method for fabricating pre-embedded channels includes the following steps:

[0100] S1. Construct the tank body;

[0101] S2. Fabricate the anchor bolt section;

[0102] S3. Combine and fix the groove made in S1 and the anchor rod made in S2 to complete the groove processing.

[0103] The pre-embedded channels processed in this scheme are as follows: Figure 1 As shown, this can be accomplished in three simple steps. Each step will be explained in further detail below.

[0104] Step S1 includes the following steps:

[0105] S101. Cut the board into a middle board 100 and two side boards 200. The middle board 100 corresponds to the middle part of the channel, and the side boards 200 correspond to the side parts of the channel.

[0106] S102. Bend the two side panels 200 respectively to make the side panels 200 into a "7" shape;

[0107] S103. A groove is formed along the length of the middle plate 100, and the groove is formed in the middle of one side of the middle plate 100 corresponding to the inner side of the groove.

[0108] S104. Several corresponding anchor bolt insertion holes are opened along the length direction of the middle plate 100, and the insertion holes pass through the groove opened in S103.

[0109] S105. Weld the edges of the side plates and the middle plate to complete the processing of the tank.

[0110] Step S2 includes the following steps:

[0111] S201. Fabricate the anchor bolt body. The anchor bolt body can be directly processed using existing technology, or a finished product can be purchased. The fabrication of the anchor bolt body is not the focus of this solution and will not be elaborated here.

[0112] S202. A plug rod is fixedly connected to one end of the anchor rod body. The plug rod is a hollow cylindrical shape and the plug rod and the anchor rod body are coaxial.

[0113] S203. Divide the insert rod into two symmetrical halves.

[0114] The insertion holes on the middle plate 100 can be square or round, depending on the processing conditions.

[0115] When the socket is round, the insert rod is cylindrical, and a dividing groove is provided along the diameter of the insert rod to divide it into two halves; when the socket is square, the insert rod is square, and a dividing groove is provided along the diagonal of the insert rod to divide it into two halves.

[0116] Step S3 includes:

[0117] S301. Insert the anchor rod into the insertion hole of the middle plate; when the rod is a square tube structure, attention should be paid to the scheme of the partition groove during insertion, and the direction of the partition groove should be perpendicular to the length direction of the middle plate 100.

[0118] S302. Bend the insert rod so that it is embedded in the groove of the middle plate; push the insert rod to deform it, and the two halves of the insert rod separated by the partition groove are squeezed toward the grooves on both sides of the corresponding insertion hole of the middle plate 100, and the squeezed and deformed insert rod is embedded in the groove.

[0119] S303. Weld the fitting joint between the insert rod and the groove to complete the groove processing.

[0120] This method differs from traditional pre-embedded channel processing. Instead of traditional hot forging, it employs a different rod-forming method, directly using cold pressing to deform the rod and integrate it with the channel, followed by welding for connection. Compared to traditional hot forging, this method consumes less energy, is safer, and can be automated on production lines, improving production efficiency and reducing manual labor.

[0121] The following solution provides a pre-embedded channel production line, which is used to process and manufacture pre-embedded channels in combination with the above-mentioned manufacturing methods.

[0122] Please see Figure 2 The display shows the overall structure of this production line. With the direction in which the material changes from sheet metal to channel product during processing as the front, this production line includes a cutting unit 1, a transfer unit 2, a shaping unit 3, and a combination unit 5 arranged sequentially from back to front.

[0123] Cutting unit 1 includes a cutting support assembly 11, a cutting assembly 12, and a cutting conveying assembly 13. Cutting assembly 12 performs laser cutting on the sheet metal. The upper side of the cutting support assembly 11 can support the sheet metal to be processed. The cutting conveying assembly 13 can convey the cut sheet metal. Transfer unit 2 is located on the discharge side of cutting unit 1 and is used for transferring sheet metal between units. Shaping unit 3 is located on one side of transfer unit 2. Shaping unit 3 includes a side plate processing assembly 31 and a middle plate processing assembly 32. Side plate processing assembly 31 can bend the side plate. Middle plate processing assembly 32 can create grooves and insertion holes in the middle of the middle plate. Combination unit 4 is located on one side of shaping unit 3 and can combine the side plate, middle plate, and anchor rod. Through the combined processing of these four units, the pre-embedded channel is finally completed. Further detailed descriptions of each unit are provided below.

[0124] Based on the above implementation plan, see Figure 3 The example shown is cutting unit 1. The cutting support assembly 11 of cutting unit 1 includes a rectangular support box 111, which is fixedly placed on the ground. Both the top and bottom sides of the support box 111 are open. Inside the support box 111, a support plate assembly 112 is installed. The support plate assembly 112 includes several support plates, with the plate surfaces vertically arranged. The upper edges of the support plates are parallel isosceles triangular plates, evenly distributed from back to front. The cutting assembly 12 uses existing technology and operates on a laser cutting method. Its cutting head can move horizontally along the X and Y axes, i.e., it can translate along the length and width of the support box 111. Unlike conventional laser cutting machines, this solution considers the transportation of the cut plate, requiring it to be transported to the next working unit. Therefore, this solution includes a cutting conveying assembly 13. The cutting conveying assembly 13 includes a cutting conveying roller frame installed inside the support box 111, which is vertically slidably connected to the support box 111. A drive mechanism is provided for the corresponding cutting conveyor roller frame. The drive component is either a pneumatic cylinder or a hydraulic cylinder, which drives the cutting conveyor roller frame to move up and down inside the carrier box 111. A cutting conveyor roller group 131 is provided on the cutting conveyor roller frame. The cutting conveyor roller group 131 includes several cutting conveyor rollers, which are arranged between two adjacent carrier plates. The cutting conveyor rollers and the cutting conveyor roller frame are rotatably connected, and the cutting conveyor rollers are driven to rotate by a motor through a combination of synchronous pulleys and synchronous belts.

[0125] During the cutting operation, the cutting conveyor roller frame descends, lowering the cutting conveyor roller group 131 below the position of the support plate group 112, ensuring stable contact between the sheet material and the support plate group 112. After the cutting operation is completed, the sheet material is divided into the middle plate portion and two side plate portions that need to be processed later. It should be noted here that for the processing of the middle plate, the cutting unit can cut only the outer edge of the sheet material, or the insertion holes on the middle plate 100 can be cut at the same time. If the insertion holes of the middle plate 100 are processed in the cutting unit 1, then this structural operation is not required later, but it also increases the processing time required by the cutting unit. This solution will later provide a processing method in which the cutting unit 1 only performs the outline cutting of the middle plate, that is, the insertion hole processing of the middle plate 100 is performed at the shaping unit 3. This can be selectively set during the implementation of the solution, and the specific details will be described later.

[0126] Based on the above implementation scheme, the cutting unit 1 also includes a receiving structure for receiving debris generated during cutting, which includes three receiving boxes 14 located at the bottom of the carrier box 111. Each receiving box 14 includes a box body and a pull rod. The box body is a flat rectangular box structure, and it is horizontally slidably connected to the bottom of the carrier box 111 in the width direction of the carrier box 111. A limiting plate is provided on the outer side of the box body, and when the box body is pushed into the carrier box 111, the limiting plate abuts against the outer side of the carrier box 111. The pull rod adopts an overall "I"-shaped structure, with its lower end rotatably connected to the outer side of the box body, and a handle fixedly installed at the other end. A vertical placement groove is provided on the outer wall of the carrier box 111 corresponding to the handle of the pull rod, and the handle of the pull rod can be placed into the placement groove.

[0127] Based on the above implementation plan, see Figures 4 to 8 The transfer unit 2 includes a transfer frame 21, a transfer conveyor roller group 22, and a transfer gripping assembly 23. The transfer frame 21 is a frame structure positioned along the conveying direction of the cutting conveyor assembly 13. The transfer conveyor roller group 22 includes several transfer conveyor rollers, which are rotatably connected to the transfer frame. A motor is mounted on the transfer frame 21, and the motor and the transfer conveyor rollers are linked via a sprocket and chain combination. In this design, the transfer frame 21 has two sets of transfer conveyor roller groups 22, each equipped with an independent motor, and the two sets of transfer conveyor roller groups 22 are arranged front and rear. This design considers the pre-embedded channel to be approximately 1.5m-2m long, and two sets of transfer conveyor roller groups 22 are sufficient. If a longer channel is desired, the number of transfer conveyor roller groups 22 can be adjusted according to the actual situation. Each transfer conveyor roller uses a combination of two rollers coaxially fixedly connected, with their middle sections joined and their two ends rotatably connected to the transfer frame 21. This connection method reduces the manufacturing and maintenance difficulty of a single transfer conveyor roller.

[0128] The transfer gripping components 23 are located on both sides of the transfer frame, arranged symmetrically. These components are used to grip the plates corresponding to the side panels. A total of four transfer gripping components 23 are provided: two are located between the transfer frame 21 and the shaping unit 3, and the other two are located on both sides of the discharge end of the shaping unit 3. The transfer gripping components 23 only need to be able to grip the plates of the side panels 200. The specific structural form of the transfer gripping components 23 can be varied; one implementation is given later in this paper.

[0129] After the cutting unit 1 cuts the sheet metal into corresponding middle plate 100 and side plate 200 pieces, its cutting conveying assembly 13 conveys the pieces as a whole to the transfer frame 21, and then the transfer conveying roller group 22 transports them forward. Two transfer gripping assemblies 23 near the transfer frame 21 grip the side plate 200 pieces and place them onto the shaping unit 3 for processing and shaping of the side plate 200. The transfer gripping assembly 23 at the discharge end of the shaping unit 3 then grips and moves the side plate 200 to the assembly unit 4.

[0130] Based on the above implementation plan, see Figure 6 The transfer gripping assembly 23 includes a transfer gripping frame 231, a first transverse frame 232, a second transverse frame 233, and a gripping fixture 234. The transfer gripping frame 231 is a fixed "gate"-shaped frame, and its fixed position is not limited. In this design, the lower end of the transfer gripping frame 231 is fixedly mounted on the base plate of the shaping unit 3. The upper part of the transfer gripping frame 231 is a horizontally arranged sliding structure, which can be a combination of a rodless cylinder or a lead screw nut with a sliding table. One end of the first transverse frame 232 is fixedly connected to the sliding structure of the transfer gripping frame 231, allowing the first transverse frame 232 to slide horizontally along the transfer gripping frame 231. The sliding direction of the first transverse frame 232 is the front-to-back direction, which is the length direction of the entire production line. The first transverse transfer frame 232 is also equipped with a sliding structure. The second transverse transfer frame 233 is slidably connected to the first transverse transfer frame 232, and its sliding direction is horizontal and perpendicular to the movement direction of the first transverse transfer frame 232. In other words, the sliding direction of the second transverse transfer frame 233 is the width direction of the production line. The gripping fixture 234 is located at the lower part of the second transverse transfer frame 233. The gripping fixture 234 can move vertically and can grip the plates on the transfer conveyor roller group 22. The gripping structure of the gripping fixture 234 can adopt a vacuum suction type or a cylinder gripper type structure. Since this solution needs to grip regularly shaped plates, there is no gripping difficulty. The specific structural form of the gripping structure can be implemented using existing technology, and will not be elaborated here.

[0131] Based on the above implementation scheme, the shaping unit 3 includes two side plate processing assemblies 31 and one middle plate processing assembly 32, with the side plate processing assemblies 31 located on both sides of the middle plate processing assembly 32. The side plate processing assemblies 31 are used to bend the cut side plate pieces, shaping them into a "7" shape. Figure 7 The side panel processing assembly 31 includes a side panel processing frame 311, a side panel rotating seat 312, and a side panel pressing component 313. The side panel processing frame 311 is a fixedly installed "7"-shaped frame, with its lower end fixedly mounted on the base of the forming unit 3. The side panel rotating seat 312 is as follows... Figure 9 As shown, it is a long rectangular block. The side plate rotating seat 312 and the base of the shaping unit 3 are rotatably connected. Several grooves are opened on the periphery of the side plate rotating seat 312. The grooves extend along the length of the side plate rotating seat 312. The grooves are "V" shaped. Grooves of different sizes and numbers are set on the four sides of the side plate rotating seat 312 to meet different bending requirements.

[0132] The side plate lower pressing component 313 and the side plate processing frame 311 are horizontally slidably connected, and the side plate lower pressing component 313 can move toward or away from the side plate rotating seat 312. The side plate lower pressing component 313 includes a hydraulic cylinder, which is horizontally slidably connected to the side plate processing frame 311. The movable end of the hydraulic cylinder is set downwards, and a long-shaped pressure plate is fixedly installed on its movable end. Several pressure blocks 3131 are detachably connected to the lower part of the pressure plate. The pressure blocks 3131 are provided with mounting holes on the upper part and are fixedly connected to the pressure plate by bolts. The thickness of the bottom edge of the pressure blocks 3131 is reduced, forming a thinner pressing hole. This structure is as follows. Figure 10 As shown, several pressure blocks 3131 are set. In this way, the downward pressure force can be better distributed, and the difficulty of subsequent equipment maintenance and repair can be greatly reduced.

[0133] Based on the above implementation scheme, the side plate lower pressure component 313 can also be fixedly connected to the side plate processing frame 311. In this connection method, it is necessary to replace the matching pressure block 3131 according to the structure of the recess on the side plate rotating seat 312.

[0134] Based on the above implementation scheme, the side plate rotating seat 312 is rotatably connected to the connecting seat on the base of the shaping unit 3 via a rotating shaft. The side plate rotating seat 312 can be adjusted manually or driven by a motor. A top block is provided below the side plate rotating seat 312. The upper surface of the top block is flat, and the top block is vertically slidably connected to the base. A hydraulic cylinder that can drive its lifting and lowering is provided on the lower side of the top block. When the required orientation of the side plate rotating seat 312 is adjusted, the top block rises and abuts against the lower side of the side plate rotating seat 312, enhancing the stability of the side plate rotating seat 312.

[0135] Based on the above implementation scheme, a horizontal positioning pin is set for the top block. The positioning pin is an electromagnetic pin. When the top block rises, the positioning pin fixes the top block.

[0136] Based on the above implementation plan, see Figure 8 The shaping unit 3 also includes a middle plate processing assembly 32, which is used to process grooves and holes in the middle plate. The middle plate processing assembly 32 includes a middle plate conveying roller group 321, a middle plate grooving assembly 322, and a middle plate hole-making assembly 323. It should be noted that the middle plate hole-making assembly 323 is used when the cutting unit 1 does not process the middle plate holes.

[0137] A groove is provided in the middle of the shaping unit 3. The middle plate conveying roller group 321 is set in the groove in the middle of the shaping unit 3. It includes several middle plate conveying rollers. Unlike the roller distribution of the transfer unit 2, the middle plate conveying rollers of the shaping unit 3 are divided into a lower roller group and an upper roller group. The lower roller group is distributed along the length of the base of the shaping unit 3. The upper roller group is located above the lower roller group. There is a gap between the upper roller group and the lower roller group to allow the middle plate 100 to pass through. The upper roller group is only set near the discharge end of the shaping unit 3. A portal frame is set at the discharge end of the shaping unit 3. The portal frame spans the groove in the middle of the shaping unit 3. The middle plate grooving assembly 322 and the middle plate perforation assembly 323 are connected to the two sides of the portal frame, respectively. The middle plate grooving assembly 322 is set on the side of the portal frame facing the transfer unit 2, and the middle plate perforation assembly 323 is set on the side of the portal frame facing the assembly unit 4. The upper roller group only extends to the position of the middle plate grooving assembly 322.

[0138] The medium plate grooving assembly 322 includes a grooving motor and a grooving cutter head. The grooving motor is connected to a cylinder and a gantry frame. The cylinder drives the grooving motor to move toward or away from the medium plate conveying roller group 321. The grooving cutter head and the motor shaft of the grooving motor are fixedly connected. Water spray nozzles are provided on the side of the medium plate grooving assembly 322 for spraying water toward the grooving cutter head to cool it down.

[0139] The middle plate opening assembly 323 includes an opening cylinder and an opening pad block disposed below the opening cylinder. An opening punch is fixedly disposed on the movable end of the opening cylinder, and a through hole is provided on the opening pad block corresponding to the opening punch.

[0140] Through the structure of this embodiment, the processing of the middle plate 100 is achieved. The middle plate piece conveyed by the transfer unit 2 falls into the base groove of the shaping unit 3, and then moves forward under the action of the middle plate conveying roller group 321. Under the clamping action of the upper roller group and the lower roller group, the middle plate grooving assembly 322 and the middle plate punching assembly 323 grooving and punching are performed. The reason for setting the middle plate grooving assembly 322 behind the middle plate punching assembly 323 is that the groove of the middle plate 100 is opened first, and then the punching is punched, which can greatly reduce the wear of the punch.

[0141] Based on the above implementation plan, see Figures 11 to 15 The assembly unit 4 includes an assembly base 41, an assembly robot 42, a middle plate pushing assembly 43, a side plate assembly mechanism 44, and an anchor bolt assembly mechanism 45. The assembly unit 4 completes the final processing of the pre-embedded channel.

[0142] The assembly base 41 is a rectangular platform fixed on the ground. The assembly robot 42 is set on both sides of the assembly base 41. The assembly robot 42 is a combination of robotic arms and tooling. The assembly robot 42 can grasp the side plate 200 processed by the shaping unit 3. The assembly robot 42 can use existing technology. The transfer gripping component 23 located at the discharge end of the shaping unit 3 in the transfer unit 2 grasps the processed side plate 100 and delivers it towards the assembly unit 4. Then, the assembly robot 42 receives it and waits for assembly and installation.

[0143] The middle plate pushing assembly 43 is located at the end of the combined base 41 near the shaping unit 3, see [reference]. Figure 12 The middle plate pushing assembly 43 includes a cleaning groove at the end of the combined base 41. An air blower 431 is arranged above the cleaning groove, and the middle plate 100 passes under the air blower 431. An air nozzle is arranged at the lower part of the air blower 431 to deliver hot air for air blowing cleaning and drying of the middle plate 100. In addition, a rotating roller 432 is arranged at the end of the cleaning groove of the middle plate pushing assembly 43 away from the shaping unit 3, and the rotating roller 432 drives the middle plate 100 to move forward.

[0144] The side plate assembly mechanism 44 is disposed on the upper side of the assembly base 41, located on both sides of the movement path of the middle plate 100. The side plate assembly mechanism 44 includes a side plate assembly fixture, which can move toward or away from the middle plate on the assembly base 41; a through welding groove is provided on the table surface of the assembly base 41, and a welding assembly is provided inside the assembly base 41 at the connection between the side plate and the middle plate. The welding assembly is disposed inside the assembly base 41 and can slide along the assembly base 41; the welding end of the welding assembly is positioned toward the welding groove of the assembly base 41.

[0145] The side plate assembly fixture includes a combination cylinder 441 and a connector 442. The combination cylinder is fixedly mounted on the platform of the assembly base 41, and the connector 442 is as follows: Figure 15 As shown, the connector 442 has a vertical slot, and the end of the connector 442 facing the discharge side is an open end.

[0146] The middle plate pushing assembly 43 pushes the middle plate 100 forward, and the combination robot 42 inserts the side plate 200 into the connector 442. Then, the combination cylinder 441 drives the side plate 200 in the connector 442 to move towards the middle plate 100 and clamp it. Then, the welding assembly welds the connection between the side plate 200 and the middle plate 100 while moving. The specific welding structure of the welding assembly and its corresponding moving structure can adopt existing technology. The key point of this solution is its application to the cooperation form of the combination unit 4, rather than the specific welding device structure itself.

[0147] Based on the above implementation scheme, the anchor bolt assembly mechanism 45 is located on the discharge side of the side plate assembly mechanism 44. The anchor bolt assembly mechanism 45 includes an anchor bolt insertion assembly 451, an insertion rod bending assembly 452, and an insertion rod welding assembly 453. The anchor bolt insertion assembly 451 is located inside the assembly base 41 and is used to transport the anchor bolt. The anchor bolt is transported in a direction where one end of the insertion rod is vertically upward. The anchor bolt insertion assembly 451 can push the anchor bolt from below to above, inserting the insertion rod into the insertion hole of the middle plate 100. The insertion rod bending assembly 452 is located above the anchor bolt insertion assembly and can bend the insertion rod of the anchor bolt. The insertion rod welding assembly 453 is located on one side of the insertion rod bending assembly and can weld the bent insertion rod. In addition, it also includes a channel conveying roller group 454, which is used to push the channel in a progressive manner. The distance of each push corresponds to the spacing of the insertion holes on the middle plate 100. That is, after each anchor is inserted, the channel is pushed to the installation position of the next anchor.

[0148] See Figures 16 to 18 The anchor bolt insertion assembly 451 includes a supply track 4511, the interior of which is a channel for the corresponding anchor bolt. A through slot for the corresponding anchor bolt insertion rod is provided at the top. A pushing structure 4512 is provided on the side of the supply track 4511, enclosing several vertically arranged pushing rollers. A belt surrounds the outer side of the pushing rollers. The pushing rollers and belt of the pushing structure 4512 extend into the supply track 4511, allowing the belt to contact the outer side of the middle of the anchor bolt. As the belt rotates, the anchor bolt is continuously pushed forward. An adjustment structure and an insertion structure are provided at the discharge end of the supply track 4511. An ejector 4513 is slidably connected to the lower part of the discharge end of the supply track 4511. A cylinder is linked to the ejector 4513, driving the ejector 4513 to move up and down. When the ejector 4513 moves upward, the anchor bolt insertion rod can be inserted into the insertion hole of the middle plate 100. In addition, considering the orientation of the slots on the insertion rod, the direction of the anchor rod needs to be adjusted. Therefore, this solution also includes the following adjustment structure.

[0149] A circular ring plate is provided on the upper part of the ejector 4513, and a positioning plate is provided in the middle diameter of the circular ring plate. A positioning groove is provided on the end face of the anchor rod away from the insertion rod, corresponding to the circular ring plate and the positioning plate. The direction of the positioning groove corresponds to the direction of the dividing groove on the insertion rod. An adjusting motor is provided on one side of the ejector 4513. The adjusting motor is rotatably connected to the ejector 4513 through a synchronous pulley and a synchronous belt. The adjusting motor and the ejector frame 4513 are connected by a support structure, which can be driven to lift and lower synchronously by the cylinder for ejection. A through hole is opened at the lower part of the supply track 4511 near the ejector 4513. The through hole is sufficient to allow the anchor rod to fall vertically. A sponge pad is provided on the side wall above the through hole to increase the friction of the anchor rod's perimeter at that location.

[0150] With this structure, when the anchor rod moves to the position of the ejector 4513, it falls onto the ejector 4513. Then, the motor drives the ejector 4513 to rotate one revolution. During the rotation of the ejector 4513, the positioning groove of the anchor rod will coincide with the annular plate and positioning plate on the ejector 4513. Then, the anchor rod continues to fall, and the upper part of the ejector 4513 is engaged in the positioning groove. The anchor rod can then rotate synchronously with the ejector 4513 to adjust to a suitable installation angle. The main function of the positioning plate is to adjust the angle of the anchor rod, while the function of the annular plate is to ensure that the anchor rod does not tilt during the ejection process.

[0151] The rod bending assembly 452 includes a hydraulic cylinder or pneumatic cylinder as the lifting driving force for bending. A long, narrow bending block is provided at the lower end of the cylinder body. A small conical protrusion is provided in the lower center of the bending block. The width of the bending block corresponds to the width of the groove in the middle plate 100, and its length is at least twice the length of the rod on the anchor rod. When the bending block moves downwards, the rod of the anchor rod can be bent to both sides, causing the anchor rod to separate and embed into the groove of the middle plate 100.

[0152] The insertion rod welding assembly 453 is a vertically set welding gun, which is also driven to rise and fall by a hydraulic cylinder or a pneumatic cylinder. The insertion rod welding assembly 453 is used to weld and fix the connection position between the groove and the insertion rod.

[0153] Based on the above implementation scheme, the channel conveying roller assembly 454 includes two vertically arranged rollers, with the channel passing between the two rollers. To ensure that the channel can smoothly enter the conveying range of the channel conveying roller assembly 454, the middle plate pushing assembly 43 also includes two pushing blocks 433. The pushing blocks 433 are rotatably connected to the combined base 41, with their rotating shafts vertically arranged. There is a gap between the pushing blocks 433, and the pushing blocks 433 are made of elastic material. When the two pushing blocks 433 rotate, their minimum distance is less than the width of the middle plate 100.

[0154] With this structure, when the middle plate 100 is being conveyed, the push block 433 can first rotate toward the shaping unit 3 to avoid the middle plate 100. After the middle plate 100 moves to the connection position with the side plate 200 and is assembled, the push block 433 rotates forward and can move the channel into the clamping range of the channel conveying roller group 454.

[0155] Based on the above implementation scheme, an electromagnetic positioning pin is installed on the combined base 41 near the anchor bolt assembly mechanism 45. When the middle plate 100 moves forward, the electromagnetic positioning pin rises, restricting the forward movement of the middle plate 100 and ensuring that it is positioned at the connection point of the matching side plate 200. After the side plate 200 and the middle plate 100 are welded together, the electromagnetic positioning pin descends, releasing the positioning.
