Description

TECHNICAL FIELD

[0001] The application relates to the technical field of sheet metal processing, in particular to sheet metal automatic folding equipment and a control process thereof. BACKGROUND

[0002] Steel office appliances and standard bedsteads use a large number of sheet metal parts, which usually need to be bent to form a box, a frame or a support structure with sufficient rigidity and specific functions. The existing folding equipment usually adopts manual support and rotation of the plate to sequentially fold the other side edges when folding the multiple edges of a large-size plate. This method is not only low in efficiency, but also causes the plate to sag due to suspension, thereby affecting the bending straightness and accuracy. After searching, the utility model patent with the patent publication number CN217121391U discloses a sheet metal folding mechanism, which achieves the effect of replacing manual work to assist in supporting the workpiece, thereby facilitating the operation of the workers and eliminating the safety hazards to a certain extent. However, the supporting structure only assists in supporting the sheet metal part, and the sheet metal part is mostly outside the bending machine. When the sheet metal part is punched and bent, the sheet metal part will be raised. Under the action of gravity, the end of the plate far from the bending end will sway, which easily affects the bending quality. In addition, the multiple edges of the sheet metal part (for example, a metal sheet) need to be folded. After the folding of one edge is completed, the worker needs to manually adjust the metal sheet so that another edge corresponds to the folding mechanism. This manual adjustment is not only time-consuming and labor-intensive, but also affects the processing efficiency. Therefore, the application provides sheet metal automatic folding equipment and a control process thereof to improve the problem. SUMMARY

[0003] The application aims to solve the problems in the background art and provides sheet metal automatic folding equipment and a control process thereof.

[0004] To achieve the above-mentioned purpose, the application specifically adopts the following technical scheme: One of the purposes of the application is to provide sheet metal automatic folding equipment, which comprises: A machine base is provided with a hydraulic push rod, the piston end of the hydraulic push rod is connected with a bending part, a die holder is arranged on the machine base and below the bending part, and a bending groove is formed in the top of the die holder; A supporting mechanism comprises two first supporting plates hingedly connected to the die holder, two second supporting plates are fixedly arranged on the machine base and support the two first supporting plates, a first mounting plate is tightly and slidably sleeved on the two first supporting plates, a first supporting seat is tightly and rotatably arranged on the first mounting plate, and a fixing part for fixing the sheet metal part is arranged on the first supporting seat; An adjustment mechanism is provided on the two second support plates, which is used to drive the first mounting plate to slide and drive the first support seat to rotate.

[0005] Furthermore, the adjustment mechanism includes a second mounting plate slidably sleeved on two second support plates, a first electric push rod installed between the second mounting plate and the base, a second support seat rotatably mounted on the second mounting plate, the second support seat and the first support seat being splinedly engaged, a driven grooved wheel fixedly mounted on the second support seat, a motor mounted on the second mounting plate, and a transmission dial fixedly mounted on the output shaft of the motor to drive the driven grooved wheel.

[0006] Furthermore, the fixing component includes a suction cup disposed on the first support, and an air pipe is connected to the suction cup via a rotary joint. The free end of the air pipe is connected to an air pump disposed on the base, and the air pipe moves through the first support and the second support in sequence.

[0007] Furthermore, two guide rods are fixedly provided at the bottom of the second mounting plate, and a support plate is slidably sleeved on the two guide rods. A return spring sleeved on the guide rod is installed between the support plate and the second mounting plate. A guide wheel is provided on the support plate, and the air pipe is wound around the guide wheel.

[0008] Furthermore, an abutment rod is slidably passed through the first mounting plate, and an abutment plate is fixedly provided at one end of the abutment rod. An abutment spring sleeved on the abutment rod is installed between the abutment plate and the first mounting plate, and an abutment wheel is provided on the abutment plate to abut and overlap with the first support plate.

[0009] Furthermore, the first support has several limiting grooves, the first mounting plate has a slot, a plug rod that slides through the slot and engages with the limiting groove, and a limiting spring is connected between the plug rod and the inner wall of the slot.

[0010] Furthermore, a buffer rod is movably passed through the second mounting plate, a buffer plate is fixedly mounted at the top of the buffer rod, a buffer spring sleeved on the buffer rod is installed between the buffer plate and the second mounting plate, and a damper is connected between the buffer plate and the second mounting plate.

[0011] Furthermore, the bending component includes a mounting bracket fixed to the piston end of the hydraulic push rod, a mounting shaft rotatably passing through the mounting bracket, two bending blades being provided on the mounting shaft, a gear being fixed on the mounting shaft, a second electric push rod being provided on the mounting bracket, and a rack being fixed to the piston end of the second electric push rod for meshing with the gear teeth.

[0012] Furthermore, a lead screw is threaded through one side of the machine base, and a positioning plate is rotatably connected to the free end of the lead screw. A guide rod with its end movable through the machine base is provided on the positioning plate.

[0013] The second objective of this application is to propose a control process for an automated sheet metal bending equipment, which is used to control the aforementioned automated sheet metal bending equipment and includes the following steps: S1: Twist the lead screw to rotate and move it, adjust the positioning plate to move it, thereby adjusting the bending length of the sheet metal part; S2: Place the sheet metal on the first support and use the air pump to use the suction cup to attach the sheet metal to the first support. S3: The first electric push rod performs work, its piston end drives the second mounting plate to move, so that one side of the sheet metal part overlaps with the positioning plate. The hydraulic push rod performs work, its piston end drives the bending part to move downward, and cooperates with the bending groove on the mold base to fold one side of the sheet metal part. During the bending process, under the action of the punching force, the first support plate rotates around the hinge point. Its rotation progress effectively follows the bending progress and effectively supports the sheet metal part. When one side is bent, the hydraulic push rod drives the bending part to return to its original position. The first support plate rotates around the hinge point to return to its original position. The first support seat and the second support seat are inserted and engaged. The first electric push rod drives the second mounting plate to move and return to its original position. The motor performs work, and with the cooperation of the transmission dial and the driven groove wheel, drives the sheet metal part to rotate 90 degrees, and then folds the other side. Repeat the steps several times, so as to bend the four sides of the sheet metal part in sequence. S4: After the four sides of the sheet metal part are bent and processed in sequence, the suction cup is released from the sheet metal part to remove it from the first support.

[0014] The beneficial effects of this application are as follows: In this application, by setting up a support mechanism, the sheet metal is initially horizontally supported, solving the problem of the sheet metal being suspended during bending. When the bent part is pressed down for bending, the stress will force the first support plate to rotate synchronously around the hinge point. Its rotation progress can accurately follow the bending progress. This follow-up support mechanism ensures that the non-bending parts of the sheet metal are always effectively supported, avoiding unexpected deformation, swaying or creases caused by sag due to gravity. This not only ensures the accuracy of each fold, but more importantly, it ensures the flatness of the overall plane of the sheet metal part, thereby significantly improving the final bending forming quality.

[0015] In this application, the adjustment mechanism, in conjunction with the support mechanism, can drive the first support seat carrying the plate to rotate precisely 90 degrees and slide horizontally. This function allows the plate to be adjusted after completing the bending of one side, and the unbent edge to be sent above the bending groove. The bending of all four sides of the plate can be completed continuously, changing the inefficient mode of relying on manual flipping and repetitive positioning in traditional operations, and greatly improving production efficiency.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0019] like Figures 1-11As shown, the automated sheet metal bending equipment proposed in some embodiments of this application includes: A base 1 is provided, on which a hydraulic push rod 2 is mounted. A bending component 3 is connected to the piston end of the hydraulic push rod 2. A die base 4 is located on the base 1 and below the bending component 3. A bending groove 5 is formed on the top of the die base 4. Preferably, the longitudinal section of the bending groove 5 is V-shaped with a 90-degree angle, used for 90-degree edge bending. The edge of the sheet metal is overlapped on the die base 4. The hydraulic push rod 2 performs work, its piston end driving the bending component 3 downwards. The bending component 3 compresses the sheet metal, and with the cooperation of the bending groove 5, a 90-degree edge bending is achieved. The die base 4 is suitable for metal sheets with a thickness of 0.5mm-3.0mm, preferably steel, aluminum, or stainless steel. Sufficient bending allowance should be reserved for the edge of the sheet metal to be bent. This allowance is usually the bending height plus the compensation amount for the sheet metal thickness and bending radius. The working pressure of the hydraulic push rod 2 can be adjusted according to the material, thickness, and bending length of the sheet metal. Its working pressure range is usually 5 MPa - 25 MPa. MPa, this pressure range is sufficient to drive the bending part 3 to complete a 90-degree bend on the sheet material within the aforementioned thickness range, while avoiding excessive pressure that could cause excessive deformation of the sheet material or damage to the mold. The supporting mechanism 6 includes two first supporting plates 601 hinged to the mold base 4, and two second supporting plates 602 fixed on the machine base 1, with the two second supporting plates 602 respectively supporting the two first supporting plates 601. Preferably, as shown in the figure... Figure 9As shown, a groove is provided on the mold base 4, and the first support plate 601 is hinged in the groove. The inner bottom wall of the groove is constructed with an overlapping platform. The end of the first support plate 601 near the bending groove 5 is constructed with an inclined surface that overlaps and engages with the overlapping platform. When the inclined surface overlaps with the overlapping platform, the top surface of the first support plate 601 is flush with one side of the bending groove 5. The second support plate 602 is horizontally fixed on the machine base 1. In the initial state, it provides horizontal support for the first support plate 601. A first mounting plate 603 is tightly slidably sleeved on the first support plate 601. A first support seat 604 is tightly rotatably mounted on the first mounting plate 603. A fixing member 605 for fixing sheet metal parts is provided on the first support seat 604. In actual use, a robotic arm can be configured next to the machine base 1. The robotic arm is used for loading or unloading materials, which is existing known technology. When stamping sheet metal, the robotic arm places the sheet metal on the first support seat 604, and the fixing member 605 holds the sheet metal in place. The material is fixed on the first support 604. At this time, the material is in a horizontal state, and the section to be bent overlaps the mold base 4. When the hydraulic push rod 2 drives the bending part 3 to move down for stamping and bending, the extrusion stress is indirectly transmitted to the first support plate 601 through the material. Under the action of stress, the first support plate 601 rotates around the hinge point. As the bending part 3 moves down, the first support plate 601 rotates synchronously. The rotation progress of the first support plate 601 effectively follows the bending progress. The two are carried out synchronously. The first support plate 601 effectively supports the material, so that the material will not sway or bend downward under the action of gravity, avoid creases in non-bending parts, and ensure bending quality. After bending one side is completed, the bending part 3 moves up, thereby relieving the resistance to the material. During the relieving process, under the action of gravity, the first support plate 601 rotates around the hinge point to reset and overlaps with the second support plate 602 again, thereby placing the material horizontally again. Adjustment mechanism 7 is set on two second support plates 602. It is used to drive the first mounting plate 603 to slide and drive the first support seat 604 to rotate. When one side of the plate is bent, adjustment mechanism 7 drives the first support seat 604 to rotate 90 degrees, thereby adjusting the orientation of the plate. The bent part is rotated and adjusted to adjust its position, and the remaining unbent part is adjusted to face the mold base 4. At the same time, adjustment mechanism 7 adjusts the first mounting plate 603 to slide, so that the part to be bent overlaps on the mold base 4, which is convenient for subsequent stamping and bending. The structure of adjustment mechanism 7 can drive the fixed plate to move and rotate. It can bend the four sides of the plate in sequence. After all four sides of the plate are bent, the fixing part 605 is released from the plate, and the plate is then removed. In this solution, by setting up a support mechanism 6, it can initially support the sheet material. When the bending component 3 is pressed down for bending, the stress will force the first support plate 601 to rotate synchronously around the hinge point. Its rotation progress can accurately follow the bending progress. This support mechanism ensures that the non-bending parts of the sheet material are always effectively supported, avoiding unexpected deformation, shaking, or creases caused by sag due to gravity, and significantly improving the final bending forming quality. At the same time, the adjustment mechanism 7 can drive the first support seat 604 carrying the sheet material to rotate 90 degrees and slide horizontally. After completing the bending of one side, the sheet material can be rotated and slid for adjustment, and the unbent edge can be pushed above the bending groove 5. The sheet material can be continuously bent on all four sides, changing the inefficient mode of relying on manual flipping and repeated positioning in traditional operations, and greatly improving production efficiency.

[0020] like Figure 5 , Figure 6 and Figure 7 As shown, the specific structure of the adjusting mechanism 7 of this application is disclosed. The adjusting mechanism 7 includes a second mounting plate 701 slidably sleeved on two second support plates 602. A first electric push rod 702 is installed between the second mounting plate 701 and the base 1. A second support seat 703 is rotatably disposed on the second mounting plate 701. The second support seat 703 is splinedly engaged with the first support seat 604. Preferably, as shown... Figure 8As shown, the second support 703 has a spline groove, and the first support 604 has a spline head that engages with the spline groove. Since the first support plate 601 moves in an arc around the hinge point, the spline groove is a conical groove with four conical petal grooves on its inner wall. The spline head is a conical head that engages with the conical groove. The conical head has four conical petal blocks that engage with the four conical petal grooves. This ensures that even if the first support plate 601 moves in an arc around the hinge point, the first support 604 can still smoothly engage with the second support 703. (It should be noted that the first mounting plate 603 is tightly sliding...) The movable sleeve is mounted on two first support plates 601. During stamping, even if the first support plate 601 is in an inclined state, the bent part of the sheet metal is located within the bending groove 5. The bending groove 5 itself provides support for the sheet metal. Therefore, the first mounting plate 603 will not slide freely along the first support plate 601 due to gravity. When the first support plate 601 rotates and resets around the hinge point, the first support seat 604 can still be smoothly inserted with the second support seat 703. At the same time, when the second support seat 703 moves, it can drive the first support seat 604 to move synchronously. When the second support seat 703 rotates, it can drive the first support seat 604 to rotate. The first electric push... When lever 702 performs work, its output shaft drives the second mounting plate 701 to slide, thereby driving the first support 604 to slide. A driven grooved wheel 704 is fixedly mounted on the second support 703. A motor 705 is mounted on the second mounting plate 701. The output shaft of the motor 705 is fixedly mounted with a transmission dial 706 that drives the driven grooved wheel 704. Preferably, the driven grooved wheel 704 includes a disc body, and the outer surface of the disc body is provided with several arc-shaped grooves and several dial slots. The number of arc-shaped grooves and dial slots is four and they are staggered. The transmission dial 706 includes a notched disc, and a dial plate is provided at the notch of the notched disc. A lever that slides with the dial slot is provided on the dial plate. The motor 705 performs work, and its output shaft drives the transmission dial 706 to rotate. When the transmission dial 706 rotates, the lever on it slides into the groove. After the transmission dial 706 rotates one revolution, the driven groove wheel 704 drives the second support 703 to rotate 90 degrees, thereby driving the first support 604 to rotate 90 degrees, so as to adjust the rotation of the plate. Preferably, the stroke of the first electric push rod 702 is set according to the maximum side length of the plate to be processed, so as to ensure that any side of the plate can be accurately fed to the top of the bending groove 5 for bending. To make the scheme more reasonable, the machine base 1 can be equipped with a PLC controller (Siemens SIMATIC). The system includes an S7-1500 series PLC and an industrial camera (Basler ACE2 series). The PLC is electrically connected to a motor 705, a first electric actuator 702, and a hydraulic actuator 2. The industrial camera is fixedly mounted above the base 1 and is used to capture images of the sheet metal located on the first support 604. Its output signal (i.e., the position, angle, and contour image information of the sheet metal) is transmitted to the PLC controller, which serves as the control core.The PLC controller receives image signals from an industrial camera and feedback signals from various actuators (motor 705, first electric actuator 702, and hydraulic actuator 2). It stores a preset control program, calculates and judges based on the input signals, and issues control commands to each actuator. Each actuator (motor 705, first electric actuator 702, and hydraulic actuator 2) receives the commands from the PLC controller and performs its actions, while simultaneously feeding back its status signals (such as reaching position, work completed, etc.) to the PLC controller.

[0021] like Figure 5 , Figure 6 and Figure 7 As shown, the specific structure of the fixing component 605 of this application is disclosed. The fixing component 605 includes a suction cup 6051 disposed on a first support 604. An air pipe 6052 is connected to the suction cup 6051 through a rotary joint 6054. The free end of the air pipe 6052 is connected to an air pump 6053 disposed on a base 1. The air pipe 6052 sequentially and movably passes through the first support 604 and the second support 703. Preferably, the first support 604 and the second support 703 have a communicating cavity. The air pipe 6052 is a plastic hose and movably passes through the cavity. When the plate is placed... When placed on the first support 604, the plate is positioned on top of the suction cup 6051. The air pump 6053 (electrically connected to the PLC controller) performs work, generating negative pressure through the air pipe 6052, which causes the suction cup 6051 to adsorb and fix the plate. The suction cup 6051 is connected to the air pipe 6052 through the rotary joint 6054, and the air pipe 6052 moves through the first support 604 and the second support 703. This allows the negative pressure adsorption to effectively fix the plate without affecting the rotation of the first support plate 601 or the first support 604.

[0022] like Figure 7As shown, a further technical solution for the trachea 6052 in this application is disclosed. Two guide rods 8 are fixedly mounted on the bottom of the second mounting plate 701. A support plate 9 is slidably sleeved on the two guide rods 8. A return spring 10 sleeved on the guide rods 8 is installed between the support plate 9 and the second mounting plate 701. A guide wheel 11 is provided on the support plate 9. The trachea 6052 is wound around the guide wheel 11. Since the first support plate 601 needs to rotate around the hinge point, and the first support seat 604 needs to rotate at the same time, the trachea 6052 also needs to move accordingly. In the initial state, it is subjected to the elastic force of the return spring 10. The section of the trachea 6052 located within the first support 604 and the second support 703 is in a taut state. When the first support plate 601 rotates, the trachea 6052 remains taut. When the first support plate 601 rotates back to its original position, the trachea 6052 also remains taut. The guide wheel 11 and the return spring 10 provide a controllable redundant length and gentle guidance for the trachea 6052, ensuring that the trachea 6052 always has a suitable tension, preventing it from sagging and interfering with moving parts, thus greatly improving the reliability of the equipment during long-term operation.

[0023] like Figure 10 As shown, a further technical solution for the first mounting plate 603 is disclosed in this application. A contact rod 12 slides through the first mounting plate 603. One end of the contact rod 12 is fixedly provided with a contact plate 13. A contact spring 14, sleeved on the contact rod 12, is installed between the contact plate 13 and the first mounting plate 603. A contact wheel 15 is provided on the contact plate 13 to contact and overlap with the first support plate 601. Preferably, the contact wheel 15 includes a wheel axle rotatably mounted on the contact plate 13, and a rubber wheel sleeve is fixed on the wheel axle. A T-shaped slider is constructed at the bottom of the first support plate 601. The first mounting plate 603 is slidably sleeved on the T-shaped slider. Under the elastic force of the contact spring 14, the contact wheel 15 abuts and overlaps with the T-shaped slider. The contact wheel 15 will undergo slight deformation under the elastic force of the contact spring 14, so that the contact wheel 15 and the T-shaped slider effectively abut. Using this abutting friction, the first mounting plate 603 cannot slide freely along the first support plate 601. It can only slide when it is pushed by the first electric push rod 702. This ensures that when the first support plate 601 rotates around the hinge point, the first mounting plate 603 cannot slide, so that when the first support plate 601 rotates around the hinge point to reset, the first support seat 604 can effectively insert and cooperate with the second support seat 703.

[0024] like Figure 11As shown, this application discloses a further technical solution for the first support 604. The first support 604 has several limiting grooves 16, and the first mounting plate 603 has a slot 17. A rod 18, which is inserted into the limiting groove 16, slides through the slot 17. A limiting spring 19 connects the rod 18 and the inner wall of the slot 17. Preferably, there are four limiting grooves 16 arranged in a ring. The limiting grooves 16 are arc-shaped with a transition arc at their opening. The insertion end of the rod 18 into the limiting groove 16 has an arc-shaped head. In the initial state, under the elastic force of the limiting spring 19, the end of the rod 18 is inserted into the limiting groove 16. When the motor 705 drives the first support 604 to rotate, since the limiting groove 16 is an arc-shaped groove and the insertion rod 18 is an arc-shaped head, the torque generated by the operation of the motor 705 can lift the insertion rod 18 away from the limiting groove 16, ensuring that the first support 604 can rotate. After the first support 604 rotates ninety degrees, the insertion rod 18 can be inserted back into the corresponding limiting groove 16 under the elastic force of the limiting spring 19, so as to ensure that the first support 604 rotates ninety degrees stably and will not deviate due to inertia (especially when the first support plate 601 rotates around the hinge point), so as to ensure that the first support 604 and the second support 703 can be effectively inserted and cooperated.

[0025] like Figure 7 As shown, a further technical solution for the first support 604 in this application is disclosed. A buffer rod 20 is movably inserted through the second mounting plate 701. A buffer plate 22 is fixed at the top of the buffer rod 20. A buffer spring 23 sleeved on the buffer rod 20 is installed between the buffer plate 22 and the second mounting plate 701. A damper 21 is connected between the buffer plate 22 and the second mounting plate 701. Due to the stress of the stamping and bending, the first support plate 601 will rotate around the hinge point and form an inclined state. After the stamping is completed, the first support plate 601 will rotate around the hinge point. The point rotation reset is achieved by setting a buffer rod 20, a buffer plate 22, and a buffer spring 23. When the first support plate 601 rotates to reset, before the first support seat 604 and the second support seat 703 are inserted, the first mounting plate 603 will first contact the buffer plate 22, thereby driving the buffer rod 20 to move down and compress the buffer spring 23. The elastic force of the buffer spring 23, in conjunction with the damper 21, is used for buffering and shock absorption, avoiding the first support seat 604 and the second support seat 703 from affecting the collision insertion, achieving a smooth and seamless insertion, thereby ensuring the stability of operation.

[0026] like Figure 4As shown, the specific structure of the bending component 3 of this application is disclosed. The bending component 3 includes a mounting bracket 301 fixed to the piston end of the hydraulic push rod 2. A mounting shaft 302 rotatably passes through the mounting bracket 301. Two folding blades 303 are provided on the mounting shaft 302. A gear 304 is fixed on the mounting shaft 302. A second electric push rod 305 (electrically connected to the PLC controller) is provided on the mounting bracket 301. A rack 306 that meshes with the teeth of the gear 304 is fixed to the piston end of the second electric push rod 305. Preferably, the mounting shaft 302 has insertion slots on both opposite sides. The two folding blades 303 are respectively inserted into the two insertion slots and then fixed by the cooperation of screw holes and screws. The folding blades 303 have different lengths. When processing a straight sheet, one folding blade 303 can be used. When processing a rectangular sheet, two folding blades 303 can be used to bend the long and short sides respectively, ensuring continuous folding of all four sides of the sheet. Preferably, the piston end stroke of the second electric push rod 305, in conjunction with the meshing of the gear 304 and rack 306, can drive the mounting shaft 302 to rotate 180 degrees. That is, when the piston end of the second electric push rod 305 is fully extended or fully retracted, the two folding blades 303 can be rotated and adjusted using the gear 304 and rack 306 to adapt to different types of sheet materials (square or rectangular) for processing.

[0027] like Figure 2 and Figure 3 As shown, this application discloses a further technical solution for sheet metal positioning. A lead screw 25 is threaded through one side of the base 1. A positioning plate 26 is rotatably connected to the free end of the lead screw 25. A guide rod 24 with its end movable through the base 1 is provided on the positioning plate 26. By rotating the lead screw 25, the positioning plate 26 is pushed, which can provide an adjustable positioning reference edge for sheet metal parts of different sizes. This can ensure that the bending allowance of the sheet metal edge is uniform, thereby further ensuring the bending quality of the sheet metal.

[0028] The control process for the automated sheet metal bending equipment, which controls the aforementioned automated sheet metal bending equipment, includes the following steps: S1: Twist the lead screw 25 to rotate and move it, adjust the positioning plate 26 to move it, thereby adjusting the bending length of the sheet metal part; S2: Place the sheet metal on the first support 604, and use the air pump 6053 to make the suction cup 6051 adsorb and fix the sheet metal on the first support 604. S3: The first electric push rod 702 performs work, and its piston end drives the second mounting plate 701 to move, so that one side of the sheet metal part overlaps with the positioning plate 26. The hydraulic push rod 2 performs work, and its piston end drives the bending part 3 to move down, cooperating with the bending groove 5 on the mold base 4 to fold one side of the sheet metal part. During the folding process, under the action of the punching force, the first support plate 601 rotates around the hinge point. Its rotation progress effectively follows the bending progress and effectively supports the sheet metal part. When one side is bent, The hydraulic push rod 2 drives the bent part 3 to return to its original position upwards. The first support plate 601 rotates around the hinge point to return to its original position. The first support seat 604 and the second support seat 703 are inserted and engaged. The first electric push rod 702 drives the second mounting plate 701 to move and return to its original position. The motor 705 performs work, and with the cooperation of the transmission dial 706 and the driven grooved wheel 704, it drives the sheet metal part to rotate 90 degrees. Then, the other side of the sheet metal part is folded. This process is repeated several times to bend the four sides of the sheet metal part in sequence. S4: After the four sides of the sheet metal part are bent and processed in sequence, the suction cup 6051 is released from the suction and fixation of the sheet metal part, thereby removing the sheet metal part from the first support 604.

[0029] The workflow of this invention is as follows: The rotating lead screw 25 moves, thereby pushing the positioning plate 26, providing an adjustable positioning reference edge for the sheet material. The sheet material is placed on the first support 604. The air pump 6053 performs work, generating negative pressure through the air pipe 6052, causing the suction cup 6051 to adhere and fix the sheet material. The first electric push rod 702 performs work, its output shaft driving the second mounting plate 701 to slide, thereby driving the first support 604 to slide, overlapping the section of the sheet material to be bent onto the mold base 4. When the hydraulic push rod 2 drives the bending part 3 downward for stamping and bending, the compressive stress is indirectly transmitted to the first support plate 601 through the sheet material. Under the action of stress, the first support plate 601 rotates around the hinge point. As the bending part 3 moves downward, the first support plate 601 rotates synchronously. The rotation progress of the first support plate 601 effectively follows the bending progress, and the two proceed synchronously. The first support plate 601 effectively supports the sheet material, preventing it from tilting downwards under gravity. Shaking or bending is used to avoid creases on non-bent areas, ensuring bending quality. After bending one side is completed, the bent part 3 moves upward, thereby releasing the resistance to the sheet material. During the release process, under the action of gravity, the first support plate 601 rotates around the hinge point to reset and overlaps with the second support plate 602 again, thus placing the sheet material horizontally again. At this time, the motor 705 performs work, and its output shaft drives the transmission dial 706 to rotate. The transmission dial 706 and the driven grooved wheel 704 cooperate... The second support 703 is rotated 90 degrees, which in turn rotates the first support 604 90 degrees, changing the orientation of the plate and adjusting the subsequent pressing part of the plate towards the mold base 4. The first electric push rod 702 pushes the first support 604 to slide again, so that the pressing part of the plate is overlapped on the mold base 4 again, thereby bending the side of the plate again. After all four sides of the plate are bent, the suction cup 6051 is released from fixing the plate, thereby removing the plate.
