Description

Technical Field

[0001] The present invention relates to the technical field of steel plate forming, and specifically, to a cold bending forming device and a forming method for steel plate production. Background Art

[0002] With the continuous development of industrial technology, cold bending forming machines have been widely used in fields such as construction and manufacturing. A cold bending forming machine can press steel coils into various shaped profiles. Among them, C-shaped steel is widely used in industries such as steel structure buildings, bridges, and machinery manufacturing due to its unique cross-sectional shape and good mechanical properties.

[0003] Currently, in the production process of C-shaped steel, a manipulator carrying an adsorption head is usually used to adsorb and transfer the pressed C-shaped steel. This method has the advantages of high automation and convenient operation. However, since there may be several mounting holes on the surface of the C-shaped steel pressed by the cold bending forming machine to facilitate the installation of fixing parts in the later stage, these mounting holes will have an adverse effect on the adsorption effect. When the adsorption head adsorbs the C-shaped steel, the existence of the mounting holes will cause the adsorption area to decrease and the adsorption force to decrease, thereby increasing the risk of the C-shaped steel falling. Once the C-shaped steel falls, it will not only affect the production efficiency but also may pose a safety hazard to the equipment and operators. Summary of the Invention

[0004] The present invention provides a cold bending forming device and a forming method for steel plate production, which solve the problem in the related technology that the adsorption area is reduced by the adsorption head due to the mounting holes on the C-shaped steel, resulting in the C-shaped steel falling.

[0039] A cold bending forming method for steel plate production, and a cold bending forming device for steel plate production produces steel plates.

[0040] The working principle and beneficial effects of the present invention are as follows:

[0041] In the present invention, in order to solve the problem that in the related art, the cold bending forming device uses an adsorption head to adsorb the C-shaped steel, the presence of the mounting holes on the C-shaped steel body will cause the adsorption area of the adsorption head to decrease and the adsorption force to decrease, thereby increasing the risk of the C-shaped steel falling. In this embodiment, the feeding is not carried out by adsorption. Instead, after the clamping member eccentrically clamps the two ends of the C-shaped steel, the clamping member rotates 180°, and the C-shaped steel is flipped so that the opening of the C-shaped steel faces downward. After the C-shaped steel falls, it is buckled with the C-shaped steel with the opening facing upward that is later conveyed into the clamping space. In this embodiment, the overall structure of the frame is stable. A pusher is installed on the frame. When the C-shaped steel comes out of the production line with the opening facing upward, the C-shaped steel is conveyed to the place where the pusher pushes. The pusher pushes the C-shaped steel into the clamping space. Under the command of the control system, the two clamping members slide along the frame and approach the C-shaped steel. The clamping members clamp the two ends of the C-shaped steel. After clamping, the clamping members start to rotate, and the C-shaped steel follows the clamping members to rotate. After rotating 180°, the clamping members flip the C-shaped steel so that the opening of the C-shaped steel faces downward. After the opening of the C-shaped steel faces downward, the two clamping members move away from each other, so that the C-shaped steel freely falls in the vertical direction and buckles with the opening of the C-shaped steel below.

[0042] Through the cooperation of the pusher and the clamping members, the automatic conveying, flipping and buckling of the C-shaped steel are realized, and the efficiency of palletizing and packing is improved. The application of the cold bending forming device and the forming method improves the automation level of steel plate production, reduces the influence of human factors on the production process, and improves the stability of product quality. And in this embodiment, the two clamping members first clamp the two ends of the C-shaped steel, then flip the C-shaped steel, and finally make the C-shaped steel freely fall, so that the upper and lower C-shaped steels are buckled with their openings up and down, forming a state similar to a cuboid, which is convenient for later packing. When the C-shaped steel is produced, it is continuously bent and cold-pressed from a steel coil. Therefore, the production of the C-shaped steel is a continuous process. This embodiment is more convenient than the method of first sucking the C-shaped steel by a manipulator and then transferring it, and the equipment cost is lower. In addition, this flipping method eliminates the step of using a push plate to squeeze the two ends of several C-shaped steels to align all the two ends of several C-shaped steels during packing, and improves the feeding efficiency.

[0056] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will describe the specific embodiments of the present invention with reference to the accompanying drawings. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, further technical solutions can be understood. Among some figures, components with the same structure or function are only schematically shown for one of them, or only one of them is marked. In this article, "one" not only means "only this one", but also means "more than one" situation, and "several" includes "two" and "more than two".

[0057] In this article, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0058] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0059] Referring to Figures 1 to 9 , for the first embodiment of the present invention, a cold bending forming device for steel plate production is proposed, which is used to form C-shaped steel. The C-shaped steel has an opening facing upward. The cold bending forming device is also used to flip the C-shaped steel so that the opening faces downward after flipping. There are two clamping members 2. The two clamping members 2 are slidably and rotatably arranged on the same side of the frame 1. There is a clamping space 21 between the two clamping members 2. After the two clamping members 2 approach each other, they are used to clamp the two ends of the C-shaped steel in the clamping space 21. After the two clamping members 2 rotate 180°, they drive the C-shaped steel to flip so that the opening faces downward; a pushing member 3, the pushing member 3 is arranged on the frame 1, and the pushing member 3 is used to push the C-shaped steel into the clamping space 21.

[0060] In this embodiment, in order to solve the problem in the related art that the cold bending forming device uses a suction head to adsorb the C-shaped steel, the mounting holes on the C-shaped steel reduce the adsorption area of the suction head, resulting in a decrease in the adsorption force and the dropping of the C-shaped steel. Instead of using the adsorption method for blanking, this embodiment uses a clamping member 2 to eccentrically clamp the two ends of the C-shaped steel, and then rotates the clamping member 2 by 180° to flip the C-shaped steel so that the opening of the C-shaped steel faces downward. After the C-shaped steel drops, it is buckled with the C-shaped steel with the opening facing upward that is later conveyed into the clamping space. In this embodiment, the overall structure of the frame 1 is stable. A pushing member 3 is installed on the frame 1. When the C-shaped steel comes out of the production line with the opening facing upward, it is conveyed to the pushing position of the pushing member 3. The pushing member 3 pushes the C-shaped steel into the clamping space 21. Under the command of the control system, the two clamping members 2 slide along the frame 1 and approach the C-shaped steel. The clamping members 2 clamp the two ends of the C-shaped steel. After clamping, the clamping members 2 start to rotate, and the C-shaped steel rotates with the clamping members 2. After rotating 180°, the clamping members 2 flip the C-shaped steel so that the opening of the C-shaped steel faces downward. After the opening of the C-shaped steel faces downward, the two clamping members 2 move away from each other, causing the C-shaped steel to fall vertically and buckle with the C-shaped steel below.

[0061] Through the cooperation of the pushing member 3 and the clamping member 2, the automatic conveying, flipping and buckling of the C-shaped steel are realized, improving the efficiency of palletizing and packing. The application of this cold bending forming device and forming method enhances the automation level of steel plate production, reduces the influence of human factors on the production process, and improves the stability of product quality. In this embodiment, the two clamping members 2 first clamp the two ends of the C-shaped steel, then flip the C-shaped steel, and finally let the C-shaped steel fall freely so that the upper and lower C-shaped steels are buckled to form a state similar to a cuboid, which facilitates later packing. When the C-shaped steel is produced, it is continuously bent and cold-pressed from a steel coil, so the production of the C-shaped steel is a continuous process. This embodiment is more convenient than the method of first sucking the C-shaped steel by a manipulator and then transferring it, and the equipment cost is lower. In addition, this flipping method eliminates the step of using a push plate to squeeze the two ends of several C-shaped steels to align the two ends of several C-shaped steels during packing, improving the blanking efficiency.

[0062] Further, the first telescopic rod 22 is arranged on the frame 1; the rotating member 23 is rotatably arranged on the first telescopic rod 22; the fixture 24 is eccentrically arranged on the rotating member 23, and the two fixtures 24 form a clamping space 21. After the first telescopic rod 22 extends, it drives the two fixtures 24 to clamp the two ends of the C-shaped steel. After the rotating member 23 drives the fixture 24 to rotate 180°, the C-shaped steel is flipped so that the opening faces downward. After the first telescopic rod 22 contracts, the C-shaped steel drops.

[0063] In this embodiment, in practical applications, the clamping member 2 is installed at a specific position on the frame 1. The first telescopic rod 22 can be a hydraulic telescopic rod or an electric telescopic rod, and is fixed on the frame 1 to ensure stable support and movement during operation. The rotating member 23 is connected to the first telescopic rod 22 through a bearing, and the rotating member 23 can rotate on the first telescopic rod 22. The fixture 24 has sufficient hardness and durability, which neither allows the C-shaped steel to fall off nor damages the C-shaped steel. When it is necessary to clamp the C-shaped steel, the first telescopic rod 22 is controlled to extend, driving the rotating member 23 and the fixture 24 to move towards both ends of the C-shaped steel, and the two fixtures 24 gradually approach and clamp both ends of the C-shaped steel. When it is necessary to turn the C-shaped steel so that the opening faces downward, the driving device of the rotating member 23 is started to make the rotating member 23 rotate. The driving device can be a motor or a hydraulic motor, and is connected to the rotating member 23 through a transmission mechanism to control the rotation angle of the rotating member 23. During the rotation process, the fixture 24 clamps the C-shaped steel to prevent the C-shaped steel from accidentally falling off.

[0064] Through the cooperation of the first telescopic rod 22 and the fixture 24, both ends of the C-shaped steel can be quickly and accurately clamped, improving production efficiency. The setting of the rotating member 23 enables the C-shaped steel to be easily turned so that the opening faces downward, facilitating subsequent processing and handling. The structural design of the clamping member 2 is reasonable, which can provide a stable clamping force to ensure that the C-shaped steel does not loosen or shift during processing. At the same time, the rotation of the rotating member 23 is stable, ensuring the accuracy and stability of the C-shaped steel turning. The clamping member 2 can be applicable to C-shaped steels of different sizes and specifications. By adjusting the size of the fixture 24, different production requirements can be met. The clamping and turning processes can be realized through an automated control system, with simple operation, reducing the labor intensity and error rate of manual operation.

[0065] Furthermore, the rotating member 23 has a mounting hole 25, and the mounting hole 25 is eccentrically arranged on the rotating member 23. The fixture 24 is rotatably arranged in the mounting hole 25. After the rotating member 23 drives the fixture 24 to rotate by more than 180°, the fixture 24 rotates along the mounting hole 25. After rotation, the C-shaped steel is further driven to rotate, and the C-shaped steel remains with the opening facing downward.

[0066] In this embodiment, in order to prevent the C-shaped steel clamped by the fixture 24 from completely overlapping the side walls on both sides of the opening of the C-shaped steel waiting in the clamping space 21, resulting in inability to buckle, it is necessary for the C-shaped steel to continue to rotate a little when it rotates 180° with the fixture 24 to the highest position, so that the upper and lower C-shaped steels are misaligned in the horizontal direction. Therefore, when manufacturing the rotating member 23, the mounting hole 25 is eccentrically arranged at a specific position thereof. The size and shape of the mounting hole 25 should match the fixture 24 to ensure that the fixture 24 can rotate within the mounting hole 25. When the C-shaped steel rotates 180° with the rotating member 23, the opening of the C-shaped steel faces downward. In order to keep the opening of the C-shaped steel facing downward all the time and facilitate the buckling of the upper and lower C-shaped steels, this embodiment designs the fixture 24 as a structure that can rotate on the rotating member 23. As long as the C-shaped steel is flipped until the opening faces downward, even if the rotating member 23 continues to rotate and the fixture 24 rotates relative to the rotating member 23, the fixture 24 will drive the C-shaped steel to always maintain the state where the opening faces downward. After the rotating member 23 rotates more than 180°, the upper and lower C-shaped steels can be buckled after the C-shaped steel falls. When the C-shaped steel offsets to a suitable position, the fixture 24 is loosened, and the C-shaped steel falls under the action of gravity to ensure the accurate falling position of the C-shaped steel. At the same time, different falling positions can also be designed according to C-shaped steels of different sizes, so that the side walls of the buckled C-shaped steels are attached, saving the step of first squeezing and compacting several columns of C-shaped steels during packaging. In this embodiment, several mounting holes 25 can be designed on the rotating member 23, and the distances of the several mounting holes 25 from the rotation center of the rotating member 23 are all different, and can be installed in different mounting holes 23 according to different C-shaped steel sizes.

[0067] By eccentrically arranging the mounting hole 25 and the rotation of the fixture 24, the rotation angle of the C-shaped steel can be accurately controlled to ensure that it accurately falls with the opening facing downward, improving the accuracy and reliability of the production process. During the falling process of the C-shaped steel, due to the control and guidance of the fixture 24, the C-shaped steel can be prevented from accidentally falling or colliding, ensuring the safety of the production process.

[0068] Furthermore, the first mounting plate 27 is arranged on the first telescopic rod 22, and the first mounting plate 27 has a guiding groove 26 in the vertical direction; the clamping block 4 is arranged on the fixture 24, and the clamping block 4 is square; the mounting block 5 is slidably arranged in the guiding groove 26; the clamping block 6 is slidably arranged on the mounting block 5 in the horizontal direction, the clamping block 6 has a clamping space 61, and the clamping block 4 is used to be clamped into the clamping space 61. After being clamped, the fixture 24 rotates along the mounting hole 25, that is, rotates relative to the rotating member 23, and after rotation, it is used to drive the C-shaped steel to have the opening facing downward.

[0069] In this embodiment, a guiding groove 26 is machined on the first mounting plate 27. The size and shape of the guiding groove 26 should match those of the mounting block 5 to ensure that the mounting block 5 can slide therein. The size and shape of the guiding groove 26 should ensure that the mounting block 5 can slide vertically therein. The clamping block 4 is designed to be square and is mounted on the fixture 24. The size of the mounting block 5 matches that of the guiding groove 26, and the mounting block 5 can slide up and down within the guiding groove 26. The clamping block 6 is mounted on the mounting block 5 and can slide horizontally. The clamping block 6 is designed with a specific clamping space 61, and the shape and size of the clamping space 61 should be able to hold the square clamping block 4.

[0070] During the actual operation process, when the rotating member 23 rotates 180°, the clamping block 4 moves to a position corresponding to the clamping block 6 as the position of the fixture 24 changes. When the rotating member 23 continues to rotate and the clamping block 4 is snapped into the clamping space 61, due to the limitation of the clamping space 61, relative rotation between the fixture 24 and the rotating member 23 is achieved, thereby driving the opening of the C-shaped steel to always face downward.

[0071] The cooperation of the guiding groove 26, the clamping block 4, the mounting block 5, and the clamping block 6 can achieve the positioning and rotation control of the fixture 24. Ensure that after the rotating member 23 rotates 180°, the fixture 24 can rotate relative to the rotating member 23, thereby driving the opening of the C-shaped steel to always face downward. The structural design and cooperation method of each component make the entire device have high stability during the working process.

[0072] Furthermore, the rotating shaft 7 is rotatably arranged on the first telescopic rod 22, the rotating member 23 is arranged on the rotating shaft 7, the rotating member 23 is rotatably arranged on the first telescopic rod 22 through the rotating shaft 7. After the rotating shaft 7 rotates, it drives the rotating member 23 to rotate. The rotating shaft 7 is rotatably arranged on the first mounting plate 27, and the rotating shaft 7 is rotatably arranged on the first telescopic rod 22 through the first mounting plate 27; one end of the connecting rod 8 is rotatably arranged on the rotating shaft 7, and the other end has a supporting end face 81. After the fixture 24 clamps the C-shaped steel, the supporting end face 81 abuts against the lower end face of the clamping block 4. The fixture 24 is fixed on the rotating member 23 through the supporting end face 81 and the clamping block 4. After the rotating member 23 rotates 180°, the supporting end face 81 separates from the lower end face of the clamping block 4, and the clamping block 4 moves into the clamping space 61. Chamfers can be designed on the clamping block 4 to facilitate the contact between the lower end face of the clamping block 4 and the supporting end face 81.

[0073] In this embodiment, during the actual manufacturing process, first, the first mounting plate 27 is fabricated and installed on the first telescopic rod 22. Ensure that the first mounting plate 27 has sufficient strength and stability to support the subsequent rotating shaft 7 and other components. Set the mounting position of the rotating shaft 7 on the first mounting plate 27 so that the rotating shaft 7 can rotate flexibly on the first mounting plate 27. First, install the rotating shaft 7 on the first telescopic rod 22 to ensure that the rotating shaft 7 can rotate flexibly on the first telescopic rod 22. The rotating member 23 is fixedly installed on the rotating shaft 7. When the rotating shaft 7 rotates, it can drive the rotating member 23 to rotate synchronously. One end of the connecting rod 8 is rotatably arranged on the rotating shaft 7. The other end of the connecting rod 8 is machined with a supporting end face 81, which should have a certain flatness and supporting strength to ensure that it can stably support the clamping block 4. During the operation, after the clamp 24 clamps the C-shaped steel, adjust the position of the connecting rod 8 so that the supporting end face 81 is in close contact with the lower end face of the clamping block 4. Chamfers can be designed on the clamping block 4 to facilitate the contact between the supporting end face 81 and the lower end face of the clamping block 4. Through the cooperation between the supporting end face 81 of the connecting rod 8 and the clamping block 4, the clamp 24 rotates synchronously with the rotating member 23, ensuring that the clamp 24 does not rotate relative to the rotating member 23 during the process of clamping and transporting the C-shaped steel. After the rotating member 23 rotates 180°, the opening of the C-shaped steel is cut and faces downward.

[0074] When it is necessary to flip the C-shaped steel so that its opening faces downward, the rotating shaft 7 starts to rotate, driving the rotating member 23 to rotate. During the rotation, the lower end face of the clamping block 4 drives the supporting end face 81 to move, and the supporting end face 81 drives the connecting rod 8 to rotate synchronously with the rotating member 23. After the rotating member 23 rotates 180°, the clamping block 4 just moves to the clamping space 61 position of the clamping block 6 and disengages from the supporting end face 81. The clamping block 4 moves into the clamping space 61, realizing the relative rotation of the clamp 24 and the rotating member 23, and further driving the movement of the C-shaped steel with its opening facing downward.

[0075] Through the cooperation between the supporting end face 81 of the connecting rod 8 and the clamping block 4, after the clamp 24 clamps the C-shaped steel, a stable angular positioning can be provided for the clamp 24, enabling the clamp 24 to rotate synchronously with the rotating member 23 without relative rotation with the rotating member 23, improving the safety and reliability of the operation.

[0076] Further, the turntable 28 is arranged on the rotating shaft 7, and the mounting hole 25 is located on the turntable 28. One end of the rotating shaft 29 is arranged on the clamping block 4, and the rotating shaft 29 is rotatably arranged in the mounting hole 25; the clamping plates 30 are arranged at the other end of the rotating shaft 29, and the two clamping plates 30 form the clamping space 61.

[0077] In this embodiment, the turntable 28 is mounted on the rotating shaft 7 and rotates with the rotation of the rotating shaft 7. Mounting holes 25 are provided on the turntable 28, and the positions of the mounting holes 25 are eccentrically arranged so that the clamp 24 can drive the C-shaped steel to rotate when rotating within the mounting holes 25. One end of the rotating shaft 29 is fixedly connected to the clamping block 4, and the size of the rotating shaft 29 is matched with that of the mounting hole 25 so that the rotating shaft 29 can rotate freely within the mounting hole 25. A clamping plate 30 is mounted at the other end of the rotating shaft 29, and the two clamping plates 30 can form a stable clamping space 61 to clamp the C-shaped steel tightly.

[0078] During operation, the first telescopic rod 22 extends, driving the first mounting plate 27, the rotating shaft 7, the turntable 28 and the clamp 24 to move towards both ends of the C-shaped steel. The two clamping plates 30 approach both ends of the C-shaped steel and clamp it. When it is necessary to flip the C-shaped steel, the rotating shaft 7 rotates, driving the turntable 28 to rotate 180°, thereby driving the clamp 24 and the C-shaped steel to flip until the opening faces downward. Adjust the rotation angle of the rotating member 23 to make the C-shaped steel fall at a suitable position, improving the adaptability of the device. After the C-shaped steels are buckled, their side walls are closely attached together, eliminating the subsequent centering step. This device can quickly and accurately complete the clamping and flipping operations of the C-shaped steel, improving production efficiency. Stable clamping and flipping can ensure the position of the C-shaped steel during the processing, reducing product defects caused by improper operation.

[0079] Furthermore, the first gear 9 is rotatably arranged on the rotating shaft 7, and the first gear 9 has a plurality of first teeth 91; one end of the second telescopic rod 10 is arranged on the first gear 9, and the other end is hinged to the clamping block 6; the second gear 110 is rotatably arranged on the rotating shaft 7, and the second gear 110 has a plurality of second teeth 111. One end of the connecting rod 8 is arranged on the second gear 110 and is rotatably arranged on the rotating shaft 7 through the second gear 110; the second mounting plate 160 is arranged on the first mounting plate 27; the third gear 170 is rotatably arranged on the second mounting plate 160, and the third gear 170 meshes with the second teeth 111; the fourth gear 140 is rotatably arranged on the second mounting plate 160. The third gear 170 and the fourth gear 140 are coaxially arranged and are located on both sides of the second mounting plate 160 respectively; the fifth gear 150 is rotatably arranged on the second mounting plate 160, the fifth gear 150 meshes with the fourth gear 140, and the fifth gear 150 meshes with the first teeth 91.

[0080] In this embodiment, in order to realize the continuous flipping of the C-shaped steel by the device, this solution needs to first realize the reciprocating movement of the connecting rod 8 and the second telescopic rod 10. When the clamping block 4 drives the connecting rod 8 to rotate with the rotating member 23, the clamping block 6 slides upward along the guide groove 26 in the reverse direction at the same time. When it slides to the position where the clamping block 4 can be inserted into the clamping space 61, that is, after the clamping block 4 is separated from the supporting end face 81, it directly slides into the clamping space 61. As the rotating member 23 continues to rotate, the clamping block 4 drives the clamping block 6 to move, and the clamping block 6 drives the second telescopic rod 10 to rotate with the rotating member 23. After the second telescopic rod 10 rotates, it drives the connecting rod 8 to rotate in the reverse direction. When the fixture 24 rotates to the position where it can clamp the C-shaped steel, the connecting rod 8 rotates in the reverse direction to near the clamping block 4. After the fixture 24 clamps the C-shaped steel, when the rotating member 23 drives the fixture 24 to rotate, the lower end face of the clamping block 4 directly contacts the supporting end face 81. To realize this process, the connecting rod 8 and the second telescopic rod 10 need to rotate in the reverse direction. In this embodiment, a gear meshing structure is adopted to realize the reverse rotation of the coaxial first gear 9 and the second gear 110, and further realize the function of the reverse rotation of the connecting rod 8 and the second telescopic rod 10. The third gear 170 meshes with the second tooth 111, and the third gear 170 transmits the rotation to the fourth gear 140. The fourth gear 140 meshes with the fifth gear 150 but does not mesh with the first gear 9. The fifth gear 150 meshes with the first gear 9. The rotation direction of the second gear 110 is opposite to that of the third gear 170 and also opposite to that of the fourth gear 140. After the fifth gear 150 meshes with the fourth gear 140, the rotation direction of the second gear 110 is the same as that of the fourth gear 140. The fourth gear 140 meshes with the first tooth 91, and further the rotation direction of the second gear 110 is opposite to that of the first gear 9.

[0081] Further, the pushing member 3 pushes the C-shaped steel in the horizontal direction, and the cold bending unit 120 is arranged on the frame 1; the second conveying member 130 is arranged on the frame 1, the cold bending unit 120 leads to the second conveying member 130, the second conveying member 130 conveys the C-shaped steel in the vertical direction, and the second conveying member 130 leads to the clamping space 21. After the pushing member 3 pushes, the C-shaped steel on the second conveying member 130 is pushed into the clamping space 21.

[0082] In this embodiment, in an actual production scenario, a pusher 3 is first set up to generate sufficient thrust in the horizontal direction to push the C-shaped steel. The pusher 3 can adopt devices such as a hydraulic push rod or an electric push rod, and its pushing distance and force are controlled by a control system. The cold bending unit 120 is installed on the frame 1 and is used for cold bending the C-shaped steel. The cold bending unit 120 can include a series of molds, cutters, and driving devices. By applying pressure to the C-shaped steel, it is bent and deformed, cut after forming the required shape, and finally enters the second conveyor 130. The second conveyor 130 is also arranged on the frame 1 and is located downstream of the cold bending unit 120. The second conveyor 130 can be a conveyor belt or the like, which can convey the C-shaped steel after cold bending processing in the vertical direction. During the conveying process, it is necessary to ensure the stable and accurate conveying of the C-shaped steel to avoid dropping or deviation. When the second conveyor 130 conveys the C-shaped steel to a position close to the clamping space 21, the pusher 3 starts to act, pushes the C-shaped steel in the horizontal direction, and pushes it from the second conveyor 130 into the clamping space 21. In this process, it is necessary to control the action timing and force of the pusher 3 to ensure that the C-shaped steel can accurately enter the clamping space 21 for subsequent processing or treatment.

[0083] Through the cooperation of the pusher 3, the cold bending unit 120, and the second conveyor 130, an automated production process of the C-shaped steel from cold bending processing to conveying and then to clamping is realized, reducing manual intervention and improving production efficiency. The second conveyor 130 can accurately convey the C-shaped steel in the vertical direction to ensure the position of the C-shaped steel. The precise pushing of the pusher 3 further ensures that the C-shaped steel can smoothly enter the clamping space 21, providing a reliable basis for subsequent operations.

[0084] The first buckling method of the C-shaped steel is as Figure 10 , when cutting materials in this embodiment, the pusher 3 pushes the C-shaped steel into the clamping space 21. The clamp 24 clamps the C-shaped steel d and starts to rotate. While rotating, the pusher 3 pushes the second C-shaped steel e into the clamping space 21 of the clamp 24. Since the C-shaped steel d will tilt and deviate in the rotation direction of the turntable 28 after the turntable 28 drives the C-shaped steel d to rotate, by pre-calculating the deviation position of the C-shaped steel d, the clamp 24 releases the C-shaped steel d, and the C-shaped steel d falls and buckles with the C-shaped steel e. The pusher 3 pushes the C-shaped steel f to the clamping space 21. The C-shaped steel f pushes the buckled C-shaped steel d and C-shaped steel e forward by a distance equal to the width of one C-shaped steel. When the C-shaped steel f is rotated, the pusher 3 pushes the C-shaped steel g to the clamping space 21. After the C-shaped steel f falls, it buckles with the C-shaped steel g, and so on in sequence.

[0085] The second buckling method of the C-shaped steel is as Figure 11, when blanking in this embodiment, the pusher 3 pushes the C-shaped steel d into the clamping space 21 of the fixture 24 to wait, and the pusher 3 pushes the C-shaped steel e into the clamping space 21. The C-shaped steel e pushes the C-shaped steel d to slide forward by a distance equal to the width of one C-shaped steel. The fixture 24 clamps the C-shaped steel e and flips it. After flipping, the C-shaped steel e offsets along the rotation direction of the turntable 28 to achieve the calculated distance by which the C-shaped steel e should be offset, so that the C-shaped steel e falls and engages with the C-shaped steel d, and this process is repeated in sequence.
