Description

Technical Field

[0001] The present invention relates to the technical field of steel plate forming, and in particular 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 roll forming machines have been widely used in the fields of construction, manufacturing, etc. Cold roll forming machines can press steel coils into profiles of various shapes, among which C-shaped steel is widely used in steel structure construction, bridges, machinery manufacturing and other industries due to its unique cross-sectional shape and good mechanical properties.

[0003] At present, in the production process of C-shaped steel, a manipulator carrying an adsorption head is usually used to adsorb and transport the pressed C-shaped steel. This method has the advantages of high degree of automation and easy 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 later installation of fixings, these mounting holes will have an adverse effect on the adsorption effect. When the adsorption head adsorbs the C-shaped steel, the presence of the mounting holes will lead to a reduction in the adsorption area and a decrease in the adsorption force, 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 may also cause safety hazards to the equipment and operators. Summary of the invention

[0015] The working principle and beneficial effects of the present invention are: In the present invention, in order to solve the problem that the cold bending forming device in the related art uses an adsorption head to adsorb C-shaped steel, the presence of the mounting hole on the C-shaped steel body will cause the adsorption area of ​​the adsorption head to be reduced, the adsorption force to be reduced, and thus the risk of the C-shaped steel falling is increased. In this embodiment, the material is not unloaded by adsorption. Instead, after the two ends of the C-shaped steel are eccentrically clamped by a clamping member, the clamping member is rotated 180° to flip the C-shaped steel so that the opening of the C-shaped steel faces downward. After the C-shaped steel falls, it interlocks with the C-shaped steel with the opening facing upward that is transported to 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, the opening faces upward, and the C-shaped steel is transported to the pusher. The pusher pushes the C-shaped steel into the clamping space. Under the command of the control system, the two clamps slide along the frame close to the C-shaped steel. The clamps clamp both ends of the C-shaped steel. After clamping, the clamping part starts to rotate, and the C-shaped steel rotates with the clamping part. After rotating 180°, the clamping part flips 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 parts move away from each other, causing the C-shaped steel to fall freely in the vertical direction and engage with the opening of the C-shaped steel below.

[0016] Through the cooperation of the pusher and the clamping member, the automatic conveying, flipping and buckling of the C-shaped steel are realized, and the efficiency of stacking and packaging 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. 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 let the C-shaped steel fall freely, so that the upper and lower C-shaped steel openings buckle up and down to form a state similar to a rectangular parallelepiped, which is convenient for later packaging. During production, C-shaped steel is formed by continuous bending and cold pressing of steel coils, so the production of C-shaped steel is a continuous process. This embodiment is more convenient than the method in which the robot first sucks the C-shaped steel and then transports it, and the equipment cost is lower. In addition, this flipping method eliminates the step of squeezing the two ends of several C-shaped steels with a push plate during packaging to align the two ends of several C-shaped steels, thereby improving the material unloading efficiency.

DETAILED DESCRIPTION

[0020] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] Reference Figure 1 to Figure 9 , which is the first embodiment of the present invention, proposes a cold bending forming device for steel plate production, which is used for forming C-shaped steel. The C-shaped steel has an opening, and the opening faces upward. The cold bending forming device is also used to flip the C-shaped steel. After the C-shaped steel is flipped, the opening faces downward. There are two clamping members 2, and 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 are close to 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 until 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.

[0024] In this embodiment, in order to solve the problem that the cold bending forming device in the related art uses an adsorption head to adsorb C-shaped steel, the mounting holes on the C-shaped steel cause the adsorption area of ​​the adsorption head to be reduced, the adsorption force is reduced, and the C-shaped steel falls, this embodiment does not use adsorption to unload materials. Instead, after the two ends of the C-shaped steel are eccentrically clamped by the clamping member 2, the C-shaped steel is turned 180° by the clamping member 2, so that the opening of the C-shaped steel faces downward, and after the C-shaped steel falls, it interlocks with the C-shaped steel with the opening facing upward that is transported to the clamping space. In this embodiment, the overall structure of the frame 1 is stable. A pusher 3 is installed on the frame 1. When the C-shaped steel comes out of the production line, the opening faces upward, and the C-shaped steel is transported to the pusher 3. The pusher 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 to approach the C-shaped steel. The clamping member 2 clamps the two ends of the C-shaped steel. After clamping, the clamping part 2 starts to rotate, and the C-shaped steel rotates with the clamping part 2. After rotating 180°, the clamping part 2 flips 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 parts 2 move away from each other, causing the C-shaped steel to fall in the vertical direction and engage with the C-shaped steel below.

[0025] Through the cooperation of the pusher 3 and the clamping member 2, the automatic conveying, flipping and buckling of the C-shaped steel are realized, and the efficiency of stacking and packaging is improved. The application of the cold-bending forming device and 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. 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 rectangular parallelepiped, which is convenient for later packaging. During production, C-shaped steel is formed by continuous bending and cold pressing of steel coils, so the production of C-shaped steel is a continuous process. This embodiment is more convenient than the method in which the robot first sucks the C-shaped steel and then transports it, and the equipment cost is lower. In addition, this flipping method eliminates the step of squeezing the two ends of several C-shaped steels with a push plate during packaging to align the two ends of several C-shaped steels, thereby improving the material unloading efficiency.

[0026] Furthermore, 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 clamp 24 is eccentrically arranged on the rotating member 23, and the two clamps 24 form a clamping space 21. After the first telescopic rod 22 is extended, it drives the two clamps 24 to clamp the two ends of the C-shaped steel. After the rotating member 23 drives the clamp 24 to rotate 180°, the C-shaped steel flips to face downward, and after the first telescopic rod 22 contracts, the C-shaped steel falls.

[0027] In this embodiment, in actual application, the clamping member 2 is installed at a specific position of the frame 1. The first telescopic rod 22 can be a hydraulic telescopic rod or an electric telescopic rod, fixed on the frame 1, to ensure that it can be stably supported and moved 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 clamp 24 has sufficient hardness and durability, and will not cause the C-shaped steel to fall or damage the C-shaped steel. When it is necessary to clamp the C-shaped steel, the first telescopic rod 22 is controlled to extend, and the rotating member 23 and the clamp 24 are driven to move toward the two ends of the C-shaped steel, and the two clamps 24 gradually approach and clamp the two ends of the C-shaped steel. When it is necessary to flip the C-shaped steel to the opening facing downward, the driving device of the rotating member 23 is started to rotate the rotating member 23. The driving device can be an electric motor or a hydraulic motor, which 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 clamp 24 clamps the C-shaped steel to prevent the C-shaped steel from accidentally falling.

[0028] Through the cooperation of the first telescopic rod 22 and the clamp 24, the two ends of the C-shaped steel can be clamped quickly and accurately, thereby improving production efficiency. The setting of the rotating member 23 enables the C-shaped steel to be easily flipped to the opening facing downward, which is convenient for subsequent processing and handling. The structural design of the clamp 2 is reasonable, and can provide a stable clamping force to ensure that the C-shaped steel will not loosen or shift during the processing. At the same time, the rotation of the rotating member 23 is stable, which ensures the accuracy and stability of the flipping of the C-shaped steel. The clamp 2 can be applied to C-shaped steels of different sizes and specifications, and by adjusting the size of the clamp 24, different production requirements can be met. The clamping and flipping process can be achieved through an automated control system, which is easy to operate and reduces the labor intensity and error rate of manual operation.

[0029] Furthermore, the rotating member 23 has a mounting hole 25, which is eccentrically arranged on the rotating member 23, and the clamp 24 is rotatably arranged in the mounting hole 25. After the rotating member 23 drives the clamp 24 to rotate more than 180°, the clamp 24 rotates along the mounting hole 25, and after the rotation, it further drives the C-shaped steel to rotate, and the C-shaped steel keeps its opening facing downward.

[0030] In this embodiment, in order to prevent the C-shaped steel clamped by the clamp 24 from completely overlapping with the side walls on both sides of the opening of the C-shaped steel waiting in the clamping space 21, resulting in failure to engage, the C-shaped steel needs to continue to rotate a little bit after following the clamp 24 to rotate 180° to the highest position, so that the upper and lower C-shaped steels are misaligned in the horizontal direction. Therefore, when making the rotating member 23, an eccentric mounting hole 25 is set at its specific position. The size and shape of the mounting hole 25 must match the clamp 24 to ensure that the clamp 24 can rotate in the mounting hole 25. When the C-shaped steel rotates 180° following the rotating member 23, the opening of the C-shaped steel faces downward. In order to keep the opening of the C-shaped steel always facing downward and facilitate the engagement of the upper and lower C-shaped steels, the clamp 24 in this embodiment is designed to be a structure that can rotate on the rotating member 23. As long as the C-shaped steel is flipped to the opening facing downward, even if the rotating member 23 continues to rotate, the clamp 24 and the rotating member 23 rotate relative to each other, and the clamp 24 will drive the C-shaped steel to keep the opening facing downward. After the rotating member 23 rotates at an angle exceeding 180°, the upper and lower C-shaped steels can be buckled after the C-shaped steel falls. When the C-shaped steel is offset to a suitable position, the clamp 24 is released, and the C-shaped steel falls under the action of gravity to ensure that the position of the C-shaped steel falling is accurate. At the same time, different falling positions can be designed according to C-shaped steels of different sizes, so that the side walls of the C-shaped steel after buckling fit together, eliminating the step of squeezing several rows of C-shaped steels flat and tight when packaging. In this embodiment, several mounting holes 25 can be designed on the rotating member 23, and the distances between the several mounting holes 25 and the rotation center of the rotating member 23 are different. According to different sizes of C-shaped steels, they can be installed in different mounting holes 23.

[0031] By eccentrically setting the mounting hole 25 and rotating the clamp 24, the rotation angle of the C-shaped steel can be precisely controlled to ensure that it accurately falls with its opening facing downward, thereby improving the accuracy and reliability of the production process. During the falling process of the C-shaped steel, the control and guidance of the clamp 24 can prevent the C-shaped steel from accidentally falling or colliding, thereby ensuring the safety of the production process.

[0032] Furthermore, the rotating member 23 has a guide groove 26 along the vertical direction, the clamping block 4 is arranged on the clamp 24, and the clamping block 4 is square; the mounting block 5 is slidably arranged in the guide groove 26; the clamping block 6 is slidably arranged on the mounting block 5 along the horizontal direction, and 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 clamp 24 rotates along the mounting hole 25, that is, it rotates relative to the rotating member 23, and after rotation, it is used to drive the C-shaped steel opening downward.

[0033] In this embodiment, when manufacturing the rotating member 23, a guide groove 26 is processed in the vertical direction. The size and shape of the guide groove 26 should ensure that the mounting block 5 can slide in the vertical direction. The clamping block 4 is designed to be square and installed on the fixture 24. The size of the mounting block 5 matches the guide groove 26, and the mounting block 5 can slide up and down in the guide groove 26. The clamping block 6 is installed on the mounting block 5 and can slide in the horizontal direction. The clamping block 6 is designed with a specific clamping space 61, and the shape and size of the clamping space 61 are capable of clamping the square clamping block 4.

[0034] In actual operation, 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 clamp 24 changes. When the rotating member 23 continues to rotate, the clamping block 4 is clamped into the clamping space 61. Due to the limit of the clamping space 61, the clamp 24 and the rotating member 23 realize relative rotation, thereby driving the C-shaped steel opening to always face downward.

[0035] The cooperation of the guide groove 26, the clamping block 4, the mounting block 5 and the clamping block 6 can realize the positioning and rotation control of the clamp 24. It is ensured that after the rotating member 23 rotates 180°, the clamp 24 can rotate relative to the rotating member 23, thereby driving the C-shaped steel opening to always face downward. The structural design and cooperation of each component make the entire device have high stability during operation.

[0036] Further, the rotating shaft 7 is rotatably set on the first telescopic rod 22, and the rotating member 23 is set on the rotating shaft 7. The rotating member 23 is rotatably set on the first telescopic rod 22 through the rotating shaft 7. After the rotating shaft 7 rotates, the rotating member 23 is driven to rotate; one end of the connecting rod 8 is rotatably set on the rotating shaft 7, and the other end has a supporting end face 81. After the clamp 24 clamps the C-shaped steel, the supporting end face 81 abuts against the lower end face of the clamping block 4. The clamp 24 is fixed to 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 is separated from the lower end face of the clamping block 4, and the clamping block 4 moves into the clamping space 61. A chamfer 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.

[0037] In this embodiment, first, the rotating shaft 7 is installed on the first telescopic rod 22 to ensure that the rotating shaft 7 can be flexibly rotated on the first telescopic rod 22. The rotating member 23 is fixedly installed on the rotating shaft 7, and 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 set on the rotating shaft 7. The other end of the connecting rod 8 is processed to form a support end face 81, and the support end face 81 must have a certain flatness and support strength to ensure that the clamping block 4 can be stably supported. During operation, after the clamp 24 clamps the C-shaped steel, the position of the connecting rod 8 is adjusted so that the support 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 support end face 81 and the lower end face of the clamping block 4. The clamp 24 rotates synchronously with the rotating member 23 through the cooperation of the support end face 81 and the clamping block 4, ensuring that there will be no rotation 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 C-shaped steel opening is cut downward.

[0038] When the C-shaped steel needs to be turned over to face the opening downward, the rotating shaft 7 starts to rotate, driving the rotating member 23 to rotate. During the rotation process, the lower end surface of the clamping block 4 drives the support end surface 81 to move, and the support end surface 81 drives the connecting rod 8 to rotate synchronously with the rotating member 23. When the rotating member 23 rotates to 180°, the clamping block 4 just moves to the clamping space 61 of the clamping block 6 and is separated from the support end surface 81. The clamping block 4 moves into the clamping space 61, realizing the relative rotation of the clamp 24 and the rotating member 23, thereby driving the C-shaped steel opening to move downward.

[0039] 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, so that the clamp 24 rotates synchronously with the rotating part 23 and does not rotate relative to the rotating part 23, thereby improving the safety and reliability of the operation.

[0040] Further, the first mounting plate 27 is arranged on the first telescopic rod 22, the rotating shaft 7 is rotatably arranged on the first mounting plate 27, the rotating shaft 7 is rotatably arranged on the first telescopic rod 22 through the first mounting plate 27, and the guide groove 26 is located on the first mounting plate 27; the rotating disk 28 is rotatably arranged on the rotating shaft 7, and the mounting hole 25 is located on the rotating disk 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 plate 30 is arranged on the other end of the rotating shaft 29, and the two clamping plates 30 form a clamping space 61.

[0041] In this embodiment, in the actual manufacturing process, firstly, the first mounting plate 27 is made, and the first mounting plate 27 is mounted 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. At the same time, a guide groove 26 is processed on the first mounting plate 27, and the size and shape of the guide groove 26 must match the mounting block 5 to ensure that the mounting block 5 can slide therein. The turntable 28 is mounted on the rotating shaft 7 and rotates with the rotation of the rotating shaft 7. The mounting hole 25 is set on the turntable 28, and the position of the mounting hole 25 is eccentrically set so that the clamp 24 can drive the C-shaped steel to rotate when rotating in the mounting hole 25. One end of the rotating shaft 29 is fixedly connected to the clamping block 4, and the size of the rotating shaft 29 must match the mounting hole 25 so that the rotating shaft 29 can rotate freely in the mounting hole 25. A clamping plate 30 is installed 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.

[0042] 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 toward the two ends of the C-shaped steel. The two clamps 30 are close to the two ends of the C-shaped steel and clamped. When the C-shaped steel needs to be flipped, the rotating shaft 7 rotates, driving the turntable 28 to rotate 180°, thereby driving the clamp 24 and the C-shaped steel to flip to the opening facing downward. The rotation angle of the rotating member 23 is adjusted so that the C-shaped steel falls at a suitable position, thereby improving the adaptability of the device. After the C-shaped steel is buckled, the side walls are tightly together, eliminating the subsequent centering steps. The device can quickly and accurately complete the clamping and flipping operations of the C-shaped steel, thereby improving production efficiency. Stable clamping and flipping can ensure the position of the C-shaped steel during the processing process, reducing product defects caused by improper operation.

[0043] Further, the first gear 9 is rotatably set 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 set on the first gear 9, and the other end is hingedly set on the clamping block 6; the second gear 110 is rotatably set 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 set on the second gear 110, and is rotatably set on the rotating shaft 7 through the second gear 110; the second mounting plate 160 is set on the first mounting plate 27; the third gear 170 is rotatably set on the second mounting plate 160, and the third gear 170 is meshed with the second teeth 111; the fourth gear 140 is rotatably set on the second mounting plate 160, and the third gear 170 and the fourth gear 140 are coaxially set and are respectively located on both sides of the second mounting plate 160; the fifth gear 150 is rotatably set on the second mounting plate 160, the fifth gear 150 is meshed with the fourth gear 140, and the fifth gear 150 is meshed with the first teeth 91.

[0044] In this embodiment, in order to realize continuous flipping of the C-shaped steel by the equipment, this scheme must first realize the reciprocating motion 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 is allowed to slide upward along the guide groove 26 in the opposite direction, and slides to the position where the clamping block 4 can be clamped into the clamping space 61, that is, the clamping block 4 is disengaged from the support end surface 81 and 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 opposite direction. When the clamp 24 rotates to the position where the C-shaped steel can be clamped, the connecting rod 8 is rotated in the opposite direction to the vicinity of the clamping block 4. After the clamp 24 clamps the C-shaped steel, the rotating member 23 drives the clamp 24 to rotate, and the lower end surface of the clamping block 4 directly contacts the support end surface 81. To achieve this process, the connecting rod 8 and the second telescopic rod 10 need to rotate in opposite directions. This embodiment adopts a gear meshing structure to achieve the coaxial first gear 9 and the second gear 110 to rotate in opposite directions, thereby achieving the function of the connecting rod 8 and the second telescopic rod 10 rotating in opposite directions. The third gear 170 is meshed with the second tooth 111, and the third gear 170 transmits the rotation to the fourth gear 140. The fourth gear 140 is meshed with the fifth gear 150 but not with the first gear 9. The fifth gear 150 is meshed with the first gear 9. The second gear 110 rotates in opposite directions to the third gear 170 and the fourth gear 140. After the fifth gear 150 is meshed with the fourth gear 140, the second gear 110 and the fourth gear 140 rotate in the same direction. The fourth gear 140 is meshed with the first tooth 91, and then the second gear 110 rotates in opposite directions to the first gear 9.

[0045] 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, and the cold bending unit 120 leads to the second conveying member 130, and 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 is pushed, the C-shaped steel on the second conveying member 130 is pushed to the clamping space 21.

[0046] In this embodiment, in an actual production scenario, a pusher 3 is first provided so that it can generate sufficient thrust in the horizontal direction to push the C-shaped steel. The pusher 3 can be a hydraulic push rod or an electric push rod, and the distance and force of its pushing can be controlled by a control system. The cold bending unit 120 is mounted on the frame 1 and is used to perform cold bending on the C-shaped steel. The cold bending unit 120 may include a series of molds, cutters and drive devices, which apply pressure to the C-shaped steel to bend and deform it, cut it after forming the desired shape, and finally enter the second conveying member 130. The second conveying member 130 is also provided on the frame 1, downstream of the cold bending unit 120. The second conveying member 130 may be a conveyor belt, etc., which can convey the C-shaped steel after cold bending in a vertical direction. During the conveying process, the stable and accurate conveying of the C-shaped steel should be ensured to avoid falling or deflection. When the second conveying member 130 conveys the C-shaped steel to a position close to the clamping space 21, the pusher 3 starts to move, pushing the C-shaped steel in the horizontal direction, and pushing it from the second conveying member 130 to the clamping space 21. In this process, the action timing and force of the pusher 3 need to be controlled to ensure that the C-shaped steel can accurately enter the clamping space 21 for subsequent processing or treatment.

[0047] Through the cooperation of the pusher 3, the cold bending unit 120 and the second conveyor 130, the automated production process of the C-shaped steel from cold bending processing to conveying and clamping is realized, which reduces manual intervention and improves 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.

[0048] The first fastening method of C-shaped steel is as follows Fig.10In this embodiment, when cutting, the pusher 3 pushes the C-shaped steel into the clamping space 21, and the clamp 24 clamps the C-shaped steel d and starts to flip. While flipping, the pusher 3 pushes the second C-shaped steel e into the clamping space 21 of the clamp 24. After the turntable 28 drives the C-shaped steel d to flip, the C-shaped steel d will tilt and offset in the rotation direction of the turntable 28. By pre-calculating the offset position of the C-shaped steel d, the clamp 24 releases the C-shaped steel d, and the C-shaped steel d falls and engages with the C-shaped steel e. The pusher 3 pushes the C-shaped steel f to the clamping space 21, and the C-shaped steel f pushes the already engaged C-shaped steel d and C-shaped steel e to slide forward a distance of the width of the C-shaped steel. When the C-shaped steel f is flipped, the pusher 3 pushes the C-shaped steel g to the clamping space 21. After the C-shaped steel f falls, it engages with the C-shaped steel g, and the process repeats in sequence.

[0049] The second fastening method of C-shaped steel is as follows Fig.11 In this embodiment, when unloading, the pusher 3 pushes the C-shaped steel d to the clamping space 21 of the clamp 24 to wait, and the pusher 3 pushes the C-shaped steel e to the clamping space 21. The C-shaped steel e pushes the C-shaped steel d to slide forward a distance of the C-shaped steel width, and the clamp 24 clamps the C-shaped steel e to flip it. After flipping, the C-shaped steel e is offset along the rotation direction of the turntable 28, and the calculated distance that the C-shaped steel e should be is achieved, so that the C-shaped steel e falls and engages with the C-shaped steel d, and reciprocates in sequence.
