Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat pipe processing, and particularly relates to a bending device and method for a heat pipe of a new energy vehicle. BACKGROUND

[0002] In a new energy vehicle, especially a pure electric vehicle, a radiator is usually equipped to ensure the safety, performance and range of the vehicle. In order to arrange an efficient heat dissipation circuit in a limited vehicle body space, the pipe structure needs to be designed into a complex bending shape according to the overall vehicle layout.

[0003] It is found through investigation that a numerical control pipe bender currently available clamps and fixes a straight pipe section to be bent by a clamping block, and then rotates the pipe around the center by a bending die, so as to realize bending. However, the bent pipe section is in a free state of suspension and without support, and the bent pipe section will swing or twist unexpectedly due to its own gravity and rotational inertia. Such uncontrolled movement is likely to cause plastic deformation of the formed section, change the predetermined angle and shape, and cause product size out of tolerance. More seriously, the shaking of the bent pipe section will directly accumulate errors, so that the finally formed pipe cannot accurately match the installation position, thereby causing assembly difficulty or interference with surrounding components. SUMMARY

[0006] Further, the sliding mechanism comprises a sliding plate, the sliding plate is slidably connected to the rotating platform, the sliding plate is fixedly connected with the bottom plate, a transmission module is installed on the sliding plate, the transmission module is used for driving the sliding plate to move, a plurality of auxiliary wheels are rotationally connected to the sliding plate, the auxiliary wheels are uniformly distributed and in contact with the rotating platform.

[0007] Furthermore, it also includes a stabilizing mechanism disposed on the support shell for stabilizing the material. The stabilizing mechanism includes an array of sliding blocks, which are slidably connected to the support shell. Each sliding block is fixedly connected to a support block. A stepper motor is mounted on the support shell, and the output shaft of the stepper motor is fixedly connected to a transmission rod. The transmission rod is rotatably connected to the support shell and threadedly connected to an adjacent sliding block. The upper side of the support block is an arc-shaped surface, and the central angle of the circle containing the arc-shaped surface is equal to 90°.

[0008] Furthermore, the support shell is provided with an array of limiting rods, and the sliding block is slidably connected to a first positioning plate and a second positioning plate. The limiting rods are used to limit the adjacent first positioning plates, and the first positioning plates are used to limit the corresponding second positioning plates.

[0009] Furthermore, a connecting rod is fixedly connected to the second positioning plate, and the sliding block is provided with a limit groove, and the connecting rod slides within the corresponding limit groove.

[0010] Furthermore, the limiting groove is composed of a first guide groove, a second guide groove, and a third guide groove, and the three are connected in sequence.

[0011] Furthermore, it also includes a winding module, which is mounted on the support plate, and a pull rope is fixed to the upper cover plate. The winding module is used to wind up the pull rope.

[0012] Furthermore, it also includes an adjusting rod, which is rotatably connected to the support plate and threadedly connected to the mounting block. The support plate is slidably connected to the mounting block.

[0013] Furthermore, it also includes a fixing plate, which is slidably connected to the base plate. All the limiting rods are fixedly connected to the fixing plate and slidably connected to the support shell. The base plate is rotatably connected to an adjusting rod two, which is used to drive the fixing plate to move. The base plate is fixedly connected to a cover plate, which is in contact with the fixing plate.

[0014] A method for bending radiator pipes in new energy vehicles, based on a bending device for radiator pipes in new energy vehicles, includes the following steps:

[0015] Step 1: Start the winding module. The winding module drives the upper cover plate to rotate by pulling the rope and removes the obstruction of all support blocks. Then, start the material feeding module and the material bending module to start bending the material.

[0016] Step 2: When the material comes into contact with the support block near the drive rod, the winding module drives the upper cover plate to reset by pulling the rope, and uses the support block near the drive rod and the upper cover plate to clamp the material.

[0017] Step 3: When the material feeding module is working, the transmission module drives the sliding plate to move. The sliding plate drives the upper cover plate and the support shell to move synchronously through the bottom plate, so that the upper cover plate and the support shell move together with the material.

[0018] Step 4: When the material bending module is working, the drive module drives the rotating platform to rotate. The rotating platform drives the upper cover plate and the support shell to rotate synchronously through the base plate, so that the upper cover plate and the support shell rotate together with the material.

[0019] Step 5: When the material bending module is working, the stepper motor drives the corresponding sliding block to move through the transmission rod, so that the support block near the transmission rod moves together with the material.

[0020] Step 6: As the sliding block near the transmission rod moves, it drives the first positioning plate to move, causing the first positioning plate to contact and press against the corresponding limiting rod, thereby making the first positioning plate dock with the corresponding second positioning plate.

[0021] Step 7: After the first positioning plate aligns with the corresponding second positioning plate, as the sliding block moves, the second positioning plate moves its connecting rod and uses the corresponding first guide groove to move the corresponding sliding block upward.

[0022] Step 8: After the corresponding sliding block moves upward, the sliding block drives the supporting block to move upward and come into contact with the material;

[0023] Step 9: The intermittent operation of the material feeding module and the material bending module causes the stepper motor to start intermittently, thereby causing the sliding block near the transmission rod to move sequentially using the second positioning plate and connecting rod on it, thus supporting the material.

[0024] The beneficial effects of this invention are as follows: This invention uses the upper cover plate and the support shell to clamp and fix the bent part of the pipe, and uses the rotation of the rotating platform to make the upper cover plate and the support shell rotate with the pipe, thereby fixing the bent part of the pipe, ensuring the stability of the pipe during movement, avoiding plastic deformation of the pipe, and thus ensuring the dimensional stability of the pipe and smooth installation.

[0025] This invention uses all sliding blocks to drive the supporting blocks on them to move upwards in sequence, and makes all the supporting blocks contact the adjacent straight pipe sections after the pipe is bent, so as to achieve the purpose of supporting and fixing the lower side of the pipe. By using the supporting blocks to support the straight pipe sections of the pipe, the straight pipe sections of the pipe are prevented from springing back, thus ensuring the effect of pipe bending.

[0026] The present invention adjusts the position of the mounting block by rotating the adjusting rod, thereby changing the height of the upper cover plate, so that the upper cover plate can press and fix pipes of different diameters. Attached Figure Description

Detailed Implementation

[0041] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0042] Example 1

[0043] A bending device for radiator pipes in new energy vehicles; please refer to the following: Figures 1-8 The system includes a base 1, a material feeding module 2 for conveying the pipeline, and a material bending module 3 for bending the pipeline. Both the material feeding module 2 and the material bending module 3 are existing equipment. A rotating platform 4 is rotatably connected to the base 1, driving the pipeline to rotate in accordance with the bending process. A drive module 5 is mounted on the base 1, consisting of a servo motor, a gear ring, and gears. The gear ring is fixedly connected to the rotating platform 4, and the gears are fixedly connected to the output shaft of the servo motor. The gears and gear ring mesh, and the drive module 5 drives the rotating platform 4 to rotate circumferentially. A base plate 6 is slidably connected, and a support plate 7 is fixedly connected to the front side of the base plate 6. The support plate 7 is provided with a mounting block 8. In this embodiment, the support plate 7 and the mounting block 8 are fixedly connected. A top cover plate 9 is hinged to the rear side of the mounting block 8. A support shell 10 is fixedly connected to the upper side of the base plate 6 by bolts. The top cover plate 9 and the support shell 10 are used to clamp the pipe together. A sliding mechanism is provided on the rotating platform 4. The sliding mechanism is used to drive the base plate 6 to slide along the rotating platform 4 to adapt to the feeding of the pipe. A controller is provided on the right side of the base 1. The controller is used to control the opening and closing of all electric equipment. For ease of description, the straight section of the pipe after bending is referred to as the "straight pipe section" and the bent section is referred to as the "bent section".

[0044] Please refer to the following: Figures 3-6The sliding mechanism includes a sliding plate 21. The rotating platform 4 is provided with a sliding groove. The sliding plate 21 is slidably connected in the sliding groove of the rotating platform 4. The sliding plate 21 is fixedly connected to the base plate 6. A transmission module 22 is installed on the sliding plate 21. The transmission module 22 consists of a servo motor, a gear, and a rack. The servo motor is fixedly connected to the sliding plate 21, the gear is fixedly connected to the output shaft of the servo motor, and the rack is fixedly connected to the rotating platform 4. The gear and the rack mesh. The transmission module 22 is used to drive the sliding plate 21 to move. Four auxiliary wheels 23 are rotatably connected on the sliding plate 21, which are evenly distributed and all in contact with the rotating platform 4.

[0045] The working principle of this embodiment:

[0046] When using this device to bend the pipe, insert the pipe into the material feeding module 2. Then, the controller starts the material feeding module 2 to begin the pipe bending operation. First, the upper cover plate 9 moves upward, rotating around the mounting block 8 and releasing its obstruction of the support shell 10. Subsequently, the pipe moves intermittently to the left under the action of the material feeding module 2. After the pipe moves a fixed distance to the left (this distance is the length of the straight pipe section), the left side of the pipe moves to the upper side of the support shell 10. At this time, the upper cover plate 9 is released to press the pipe, thus using the support shell 10 and the upper cover plate 9 to fix the pipe together. Then, the controller starts the material bending module 3 and the drive module 5. The material bending module 3 begins to squeeze the pipe. Taking the material bending module 3 squeezing the pipe backward as an example, the material bending module 3 pushes the left side of the pipe to rotate clockwise (to... Figure 1 (Based on the top view perspective), during this process, the drive module 5 drives the rotating platform 4 to rotate clockwise. The rotating platform 4 drives the support shell 10 and the upper cover plate 9 to rotate clockwise together with the pipeline through the base plate 6, support plate 7 and mounting block 8, thereby ensuring the stability of the pipeline during the bending process. After the pipeline is bent to a fixed angle (this angle is the degree of bending of the bent part, and this article takes a pipeline bending of 180° as an example), the material bending module 3 and the drive module 5 are turned off, completing the first bending operation of the pipeline. At this time, the support shell 10 and the upper cover plate 9 are both located on the right side of the rotating platform 4.

[0047] During the bending and rotation of the pipe, while the pipe bends and rotates around the center of the bend, the pipe will slide along its axis within the clamping area of ​​the support shell 10 and the upper cover plate 9. The distance of this relative movement is consistent with the distance between two adjacent straight pipe sections, and the end of the pipe gradually approaches the mounting block 8.

[0048] After the first bend is completed, the material feeding module 2 pushes the pipeline to the left again. At the same time, the controller starts the transmission module 22, which sequentially drives the sliding plate 21, the base plate 6, the support plate 7, the mounting block 8, the support shell 10, and the upper cover plate 9 to move to the left synchronously. This ensures that the support shell 10 and the upper cover plate 9 remain relatively stationary with respect to the pipeline, guaranteeing the stability of the pipeline during the feeding process. After the material feeding module 2 pushes the pipeline to the left a fixed distance, the support shell 10 and the upper cover plate 9 both move to the left side of the rotating platform 4, and the controller shuts down the material feeding module 2 and the transmission module 22.

[0049] After shutting down the transmission module 22, the controller restarts the material bending module 3 and the drive module 5. The material bending module 3 squeezes the material forward, forming a new bend in the pipe (second bend) and causing the pipe to rotate counterclockwise. During this process, the drive module 5 drives the support shell 10 and the upper cover plate 9 to rotate counterclockwise through the rotating platform 4 and a series of parts, so that the support shell 10, the upper cover plate 9 and the pipe rotate synchronously, thereby forming the second bend in the pipe. After the pipe is bent at a fixed angle, the material bending module 3 and the drive module 5 stop, and the second bend of the pipe is completed. The controller shuts down the material bending module 3 and the drive module 5, and the support shell 10 and the upper cover plate 9 move to the right side of the rotating platform 4.

[0050] After the second bend is completed, the process of pushing the material to the left by the material feeding module 2 is repeated to complete the feeding of the pipe. Then, the operation of squeezing the pipe by the material bending module 3 is repeated to bend the pipe. After repeated pipe feeding and pipe bending, when the pipe bending is completed, the material feeding module 2, material bending module 3, drive module 5 and transmission module 22 are closed, the upper cover plate 9 is lifted and the bent pipe is removed.

[0051] Example 2

[0052] Based on Example 1, please refer to... Figures 5-13 It also includes a stabilizing mechanism, which is set on the support shell 10 to provide stable support for the pipeline. The stabilizing mechanism includes several sliding blocks 31 arranged in an array. The sliding blocks 31 are slidably connected to the support shell 10. A support block 32 is fixed to the upper side of the sliding block 31. The support block 32 is a rubber block. The upper side of the support block 32 is an arc-shaped surface, and the central angle of the circle containing the arc-shaped surface is equal to 90°. A stepper motor 33 is installed on the support shell 10. The output shaft of the stepper motor 33 is fixed to a transmission rod 34. The transmission rod 34 is threaded and rotatably connected to the support shell 10. The transmission rod 34 is threaded to the adjacent sliding block 31. Initially, the leftmost support block 32 is located on the upper side of the support shell 10, and the remaining support blocks 32 are all located inside the support shell 10.

[0053] Please refer to the following:Figures 8-13 The support shell 10 is provided with an array of limiting rods 41. In this embodiment, the support shell 10 and the limiting rods 41 are fixedly connected. The sliding block 31 is slidably connected to the first positioning plate 42 and the second positioning plate 43. The limiting rods 41 are used to limit the adjacent first positioning plate 42. Both the limiting rods 41 and the first positioning plate 42 are provided with inclined surfaces. Both the first positioning plate 42 and the second positioning plate 43 are provided with limiting protrusions. When the first positioning plate 42 and the second positioning plate 43 are connected, the first positioning plate 42 can drive the second positioning plate 43 to move.

[0054] Please refer to the following: Figure 8 and Figures 10-13 A connecting rod 51 is fixed to the second positioning plate 43. Except for the leftmost one, the other sliding blocks 31 are provided with limit grooves 52. The connecting rod 51 slides in the corresponding limit groove 52, and the inner wall of the limit groove 52 is set as a rough surface, that is, there is resistance when the connecting rod 51 slides in the corresponding limit groove 52. The limit groove 52 is composed of a first guide groove 521 on the right, a second guide groove 522 in the middle, and a third guide groove 523 on the left, and the three are connected in sequence. The first guide groove 521 is an inclined groove, with its left side higher than its right side. The second guide groove 522 is a horizontal groove, and the third guide groove 523 is a vertical groove (see reference). Figure 12 The second guide groove 522 is located between the first guide groove 521 and the third guide groove 523. In the initial state, the first connecting rod 51 on the left is located in the second guide groove 522 on the second sliding block 31, and the remaining connecting rods 51 are all located in the corresponding third guide groove 523.

[0055] The working principle of this embodiment:

[0056] Following the process of Example 1, when the left side of the pipe moves to the upper side of the support shell 10, the left side of the pipe will contact the first support block 32 (from left to right). At this time, the support block 32 supports the lower side of the pipe, and the support block 32 and the upper cover plate 9 together clamp and fix the pipe.

[0057] During the first bend of the pipe, the controller simultaneously activates the material bending module 3 and the stepper motor 33. The pipe then begins to bend, and it moves relative to the upper cover plate 9 (i.e., gradually approaching the mounting block 8). During this process, the output shaft of the stepper motor 33 drives the transmission rod 34 to rotate. The transmission rod 34 moves the first sliding block 31, which in turn moves the corresponding support block 32, causing the support block 32 to gradually approach the mounting block 8. The speed at which the stepper motor 33's output shaft drives the sliding block 31 to move is consistent with the relative movement speed of the pipe and the upper cover plate 9. This ensures that the first support block 32 remains in contact with the pipe, further guaranteeing the stability of the pipe during movement. Simultaneously, the support block 32's support prevents relative movement between the pipe and the support shell 10, reducing wear on the pipe from the support shell 10 and ensuring the pipe's quality. When the sliding block 31's movement distance matches the interval between two adjacent straight pipe sections, the controller shuts off the stepper motor 33, and the pipe and the upper cover plate 9 stop moving relative to each other.

[0058] During the forward movement of the first sliding block 31 (the orientation of this section can be referenced) Figure 9 The sliding block 31 drives the first positioning plate 42 to move forward, while the second positioning plate 43 moves relative to the sliding block 31. When the first positioning plate 42 contacts the corresponding limiting rod 41, the limiting rod 41 presses against the first positioning plate 42, causing the first positioning plate 42 to slide to the left along the sliding block 31. As the limiting rod 41 presses, the first positioning plate 42 gradually approaches the corresponding second positioning plate 43. After the second positioning plate 43 and the first positioning plate 42 are aligned, the sliding block 31 drives the second positioning plate 43 through the first positioning plate 42. As plate 43 moves, the second positioning plate 43 drives the connecting rod 51 on it to move. The connecting rod 51 slides along the second guide groove 522. When the connecting rod 51 enters the second guide groove 521, as the connecting rod 51 moves, it presses against the first guide groove 521, causing the second sliding block 31 to move upward. The second sliding block 31 drives the supporting block 32 on it to move upward. When the connecting rod 51 moves to the front end of the second guide groove 521, the second supporting block 32 moves to the upper side of the support shell 10 (e.g., ...). Figure 6 As shown), the stepper motor 33 stops working, which completes the first bend. At this time, the second straight section of the pipe comes into contact with the second support block 32.

[0059] As the second sliding block 31 moves upward, it drives its own first positioning plate 42 and second positioning plate 43 to move upward synchronously. At this time, the connecting rod 51 on the second positioning plate 43 moves upward and slides upward along the third guide groove 523. That is, the second connecting rod 51 cannot drive the third sliding block 31 to move upward, and when the second connecting rod 51 stops moving upward, the second connecting rod 51 enters the third guide groove 522.

[0060] During the second bending operation, the controller restarts the stepper motor 33. The output shaft of the stepper motor 33 drives the first sliding block 31 to continue moving through the transmission rod 34. The first sliding block 31 drives the second sliding block 31 to move through the second positioning plate 43 and the connecting rod 51 on it. The second sliding block 31 drives the first positioning plate 42 on it to move. When the second first positioning plate 42 contacts and presses against the corresponding limit rod 41, the second first positioning plate 42 docks with the second second positioning plate 43. Then, the second sliding block 31 drives the second connecting rod 51 to move through the first positioning plate 42 and the second positioning plate 43 on it. The second connecting rod 51 slides along the third second guide groove 522. After the second connecting rod 51 enters the third first guide groove 521, the second connecting rod 51 drives the third sliding block 31 to move upward through the third first guide groove 521. When the second connecting rod 51 moves to the front end of the third first guide groove 521, the controller shuts off the stepper motor 33, thus completing the second bending. At this time, the third straight section of the pipe contacts the support block 32.

[0061] During the upward movement of the third sliding block 31, the third sliding block 31 drives the connecting rod 51 to move upward through the first positioning plate 42 and the second positioning plate on it. The third connecting rod 51 slides upward along the fourth third guide groove 523. When the third sliding block 31 stops moving upward, the third connecting rod 51 moves into the fourth second guide groove 522.

[0062] After the second bending operation is completed, all the above operations are repeated. All the sliding blocks 31 drive the supporting blocks 32 on them to lift up in sequence, so that all the supporting blocks 32 contact the adjacent straight pipe sections of the bent pipe. The supporting blocks 32 support the pipe and improve the stability of the pipe during movement. The stepper motor 33 is turned off after the pipe bending is completed.

[0063] Example 3

[0064] Based on Example 2, please refer to... Figures 3-7It also includes a winding module 61, which is an existing winch. The winding module 61 is installed on the support plate 7. A pull rope 62 is fixed to the rear of the upper side of the upper cover plate 9. The winding module 61 is used to wind up the pull rope 62. After the pipe needs to be bent, the winding module 61 is started. The winding module 61 starts to wind up the pull rope 62. The pull rope 62 drives the rear of the upper cover plate 9 to move upward, so that the upper cover plate 9 begins to slowly rotate around the mounting block 8. At this time, the upper cover plate 9 loses its obstruction of the pipe, so the bent pipe can be removed. After the next pipe is bent, when the end of the new pipe contacts the first support block 32, the winding module 61 rotates in the opposite direction and releases the pull rope 62, so that the upper cover plate 9 returns to its original position and presses down on the pipe. Then the winding module 61 is turned off to ensure the stability of the pipe bending process.

[0065] Example 4

[0066] Based on Example 3, please refer to... Figures 4-7 It also includes an adjusting rod 71, which is threaded and has a hexagonal protrusion on its lower side. The adjusting rod 71 can be rotated with a wrench for easy operation. The adjusting rod 71 is rotatably connected to the support plate 7 and threadedly connected to the mounting block 8. The support plate 7 and the mounting block 8 are slidably connected. The position of the mounting block 8 is adjusted according to the diameter of the bent pipe, so that the upper cover plate 9 can press on pipes of different diameters. When the diameter of the bent pipe increases, the adjusting rod 71 is rotated with a wrench, causing the adjusting rod 71 to move... The mounting block 8 moves upward, causing the front side of the upper cover plate 9 to move upward. At the same time, the winding module 61 is activated, and the winding module 61 begins to slowly wind up the pull rope 62. The pull rope 62 pulls the rear side of the upper cover plate 9 upward, thus causing the upper cover plate 9 to slowly move upward in a horizontal state until the upper cover plate 9 is adjusted to a suitable height. Then, the winding module 61 is closed and the rotation of the adjusting rod 71 is stopped. During this process, the pull rope 62 remains taut. If the pipe diameter decreases, the adjusting rod 71 is rotated in the opposite direction, and the winding module 61 is controlled to slowly release the pull rope 62.

[0067] Example 5

[0068] Based on Example 4, please refer to... Figure 5 , Figure 6 and Figures 8-10It also includes two symmetrically distributed fixed plates 81, both of which are slidably connected to the base plate 6. All the limiting rods 41 are fixedly connected to the two fixed plates 81 and slidably connected to the support shell 10. The base plate 6 is rotatably connected to an adjusting rod 82. One end of the adjusting rod 82 located outside the base plate 6 is provided with a hexagonal protrusion. The adjusting rod 82 can be rotated with a wrench. The adjusting rod 82 is provided with threads. The threaded part of the adjusting rod 82 is used to drive the fixed plates 81 to move. The base plate 6 is fixedly connected to a cover plate 83, which is used to support all the fixed plates 81. The cover plate 83 is in contact with the fixed plates 81.

[0069] The working principle of this embodiment:

[0070] Before bending the pipe, all the limiting rods 41 are adjusted according to the interval between two adjacent straight pipe sections after bending. Taking the initial minimum interval as an example, when the interval between two adjacent straight pipe sections increases, the adjusting rod 82 is rotated with a wrench. The adjusting rod 82 drives the two fixed plates 81 to move forward through its thread. The two fixed plates 81 together drive all the limiting rods 41 to move forward, thereby increasing the distance between the limiting rods 41 and the adjacent first positioning plate 42, thus delaying the contact between the first positioning plate 42 and the adjacent limiting rod 41, thereby delaying the lifting time of the next sliding block 31. This makes the lifting time of the sliding block 31 correspond to the straight pipe section, improving the applicability of the device. At the same time, the number of rotations of the output shaft of the stepper motor 33 is adjusted to extend the travel of the sliding block 31, so that the single travel of the sliding block 31 corresponds to the distance between the limiting rod 41 and the adjacent first positioning plate 42. If the interval between two adjacent straight pipe sections decreases, the adjusting rod 82 is rotated in the opposite direction.

[0072] A bending method for radiator pipes in new energy vehicles; please refer to the following: Figures 1-13 The specific steps of a bending device for a radiator pipe in a new energy vehicle are as follows:

[0073] Step 1: Start the winding module 61. The winding module 61 drives the upper cover plate 9 to rotate through the pull rope 62 and removes the obstruction of all support blocks 32. Then start the material feeding module 2 and the material bending module 3 to start bending the material.

[0074] Step 2: When the material comes into contact with the support block 32 near the transmission rod 34, the winding module 61 drives the upper cover plate 9 to reset through the pull rope 62, and uses the support block 32 near the transmission rod 34 and the upper cover plate 9 to clamp the material.

[0075] Step 3: When the material feeding module 2 is working, the transmission module 22 drives the sliding plate 21 to move. The sliding plate 21 drives the upper cover plate 9 and the support shell 10 to move synchronously through the base plate 6, so that the upper cover plate 9 and the support shell 10 move together with the material.

[0076] Step 4: When the material bending module 3 is working, the drive module 5 drives the rotating platform 4 to rotate. The rotating platform 4 drives the upper cover plate 9 and the support shell 10 to rotate synchronously through the base plate 6, so that the upper cover plate 9 and the support shell 10 rotate together with the material.

[0077] Step 5: When the material bending module 3 is working, the stepper motor 33 drives the corresponding sliding block 31 to move through the transmission rod 34, so that the support block 32 close to the transmission rod 34 moves together with the material.

[0078] Step 6: As the sliding block 31 moves closer to the transmission rod 34, the sliding block 31 drives the first positioning plate 42 to move, so that the first positioning plate 42 contacts and presses against the corresponding limiting rod 41, thereby making the first positioning plate 42 dock with the corresponding second positioning plate 43.

[0079] Step 7: After the first positioning plate 42 docks with the corresponding second positioning plate 43, as the sliding block 31 moves, the second positioning plate 43 drives the connecting rod 51 on it to move and uses the corresponding first guide groove 521 to drive the corresponding sliding block 31 to move upward.

[0080] Step 8: After the corresponding sliding block 31 moves upward, the sliding block 31 drives the supporting block 32 to move upward and come into contact with the material;

[0081] Step 9: The intermittent operation of the material feeding module 2 and the material bending module 3 causes the stepper motor 33 to start intermittently, thereby causing the sliding block 31 near the transmission rod 34 to move sequentially using the second positioning plate 43 and the connecting rod 51, thus supporting the material.

[0082] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
