Description
Technical Field
[0001] This invention belongs to the field of power fittings processing technology, specifically relating to a power fittings manufacturing and forming device and its forming method. Background Technology
[0002] Iron or aluminum metal accessories widely used in power transmission lines are collectively referred to as hardware. Hardware comes in many varieties and has different uses. For example, there are various clamps for installing conductors, various hanging rings for forming insulators, various crimping tubes and repair tubes for connecting conductors, various types of spacers on split conductors, etc. In addition, there are various guy wire hardware for poles and towers, as well as hardware used to protect conductors of different sizes. They must be used in combination. Most hardware needs to withstand large tensile forces during operation, and some also need to ensure good electrical contact. It is related to the safety of conductors or poles and towers. Even if one is damaged, it may cause line faults. The quality, correct use and installation of hardware have a certain impact on the safe power transmission of the line.
[0003] Cable clamps are a type of electrical fitting used to prevent cables from loosening. Existing forming equipment typically processes steel plates by stamping them using a stamping mechanism. While this can achieve the desired clamp shape, it requires multiple stamping operations by workers, making the process cumbersome and reducing efficiency. Furthermore, workers need to manually limit the movement during stamping, increasing labor costs and potentially causing mechanical injuries. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a power fitting manufacturing and forming device and a forming method thereof.
[0005] The technical solution adopted to solve the above technical problems is: a power fitting manufacturing and forming device, including a support mechanism, wherein the support mechanism is provided with an upper feeding mechanism and a lower feeding mechanism;
[0006] A punching mechanism is installed at one end of the support mechanism, a buffer mechanism is installed at the bottom of the punching mechanism, a forming mechanism is installed at the rear end of one side of the top of the support mechanism, a driving mechanism is installed at the top of the support mechanism on the other side of the forming mechanism, and a limit mechanism is fixedly connected at the top of the support mechanism at the front end of the forming mechanism.
[0007] Furthermore, the support mechanism includes a processing table, one side of which has a feeding port and the other side has a discharging port. A unloading platform is fixedly connected to the other side of the processing table, and a discharge trough is provided on the top of the unloading platform.
[0008] With the above technical solution, workers can feed materials through the discharge port and collect the formed steel plates through the discharge chute. The whole process is carried out in an orderly manner, which improves the stability of steel plate processing.
[0009] Furthermore, the upper feeding mechanism includes a first rotating shaft rotatably connected between the inner walls of the front and rear ends of the processing table. Multiple second rotating shafts are rotatably connected to the inner walls of the front and rear ends of the processing table at a position on one side of the first rotating shaft. A first synchronous pulley is fixedly connected to the front end of the outer wall of each of the multiple second rotating shafts. A first synchronous belt is installed between every two first synchronous pulleys. A second synchronous pulley is fixedly connected to the front end of the outer wall of both the first rotating shaft and a nearby second rotating shaft. A second synchronous belt is installed between two second synchronous pulleys. A feeding roller is fixedly connected to the center of the outer wall of both the first and second rotating shafts. A fixed sleeve is rotatably connected to the rear end of the outer wall of both the first and second rotating shafts. The inner walls of the multiple fixed sleeves are fixedly connected to the outer wall of the processing table. A first machine base is fixedly connected to one side of the top of the processing table. A first servo motor is fixedly connected to the top of the first machine base. A third synchronous pulley is fixedly connected to the output shaft of the first servo motor and the front end of the outer wall of the first rotating shaft. A third synchronous belt is installed between two of the third synchronous pulleys.
[0010] With the above technical solution, when feeding the steel plate to be formed, the first servo motors in the upper and lower feeding mechanisms are activated. The output shafts of the two first servo motors rotate, driving the third synchronous pulleys connected to them to rotate, which in turn drives the two third synchronous belts connected to them to rotate. The other two third synchronous pulleys connected to them rotate accordingly, driving the corresponding first rotating shafts to rotate. The rotation of the two first rotating shafts drives the feeding rollers and second synchronous pulleys connected to them to rotate. The rotation of the two second synchronous pulleys drives the second synchronous belts connected to them to rotate, thereby driving the other two second synchronous pulleys connected to them to rotate, which in turn drives the second rotating shafts connected to them to rotate. This cycle continues, and the rotation of multiple second rotating shafts drives the feeding rollers connected to them to rotate. At the same time, the output shaft of the first servo motor in the upper feeding mechanism rotates clockwise, and the output shaft of the first servo motor in the lower feeding mechanism rotates counterclockwise, thereby realizing the conveying of the steel plate to be processed.
[0011] Furthermore, the upper feeding mechanism has the same structure as the lower feeding mechanism.
[0012] Through the above technical solution, the upper feeding mechanism and the lower feeding mechanism have a relatively compact structure. At the same time, the width of the feeding roller is the same as the width of the steel plate to be processed, and the width of the steel plate to be processed is the same as the width of the feeding port. This allows the steel plate to be processed to be stably conveyed in the processing table, preventing the steel plate to be processed from shifting, and improving the stability and accuracy of steel plate forming.
[0013] Furthermore, the punching mechanism includes a support frame fixedly connected to the other side of the top of the processing table, a hydraulic cylinder fixedly connected to the top of the support frame, a punching knife fixedly connected to the bottom end of the piston of the hydraulic cylinder, and a knife holder fixedly connected to the other side of the bottom inner surface of the processing table.
[0014] With the above technical solution, after the steel plate is formed, it needs to be cut. The cut part is the formed clamp. The hydraulic cylinder is started, and the hydraulic cylinder pushes the stamping knife through the piston, so that the stamping knife stamps the steel plate. When the bottom of the stamping knife is in contact with the top of the knife holder, the formed steel plate is cut off without the need for manual cutting by the staff, thus avoiding accidental injury to the staff caused by the punching mechanism.
[0015] Furthermore, the buffer mechanism includes two fixed cylinders fixedly connected to the other side of the top of the processing table, and a buffer spring is fixedly connected inside each of the two fixed cylinders. A connecting plate is fixedly connected to the outer wall of the hydraulic cylinder piston, and two buffer columns are fixedly connected to the bottom of the connecting plate. The two buffer columns are slidably connected to the two fixed cylinders respectively.
[0016] Through the above technical solution, when the hydraulic cylinder is running, the connecting plate connected to the hydraulic cylinder piston moves downward, thereby pushing the two buffer columns connected to it. This causes the bottom ends of the two buffer columns to squeeze the corresponding buffer springs, thereby achieving a buffering effect on the stamping knife, preventing excessive pressure from the hydraulic cylinder and excessive thrust applied to the stamping knife, avoiding damage when the stamping knife and the knife holder are stamped, and further improving the service life of the stamping knife.
[0017] Furthermore, the forming mechanism includes a fixed base fixedly connected to the rear end of the top of the unloading platform. A third rotating shaft is rotatably connected to the front end of the fixed base. A connecting plate is fixedly connected to the front end of the third rotating shaft. An upper forming column is fixedly connected to the front end of the connecting plate. A lower forming column is fixedly connected to the front end of the connecting plate near the bottom of the upper forming column. A lower bending column is fixedly connected to the front end of the connecting plate near the side of the lower forming column. A connecting shaft is fixedly connected to the front end of the connecting plate near the top of the upper forming column. An upper bending column is rotatably connected to the outer wall of the connecting shaft.
[0018] Through the above technical solution, when one end of the steel plate is conveyed to the top of the unloading platform by the upper and lower feeding mechanisms and inserted into the gap between the upper and lower forming columns, simultaneously fitting against the inner walls of the upper and lower forming columns, the second servo motor is activated. The second servo motor rotates its output shaft, driving a gear to rotate. The gear rotates, driving a meshing gear ring to rotate. The gear ring rotates, driving a third rotating shaft fixedly connected to it to rotate. The third rotating shaft rotates, driving a connecting disc to rotate. The rotating connecting disc, in turn, causes the upper forming column, lower forming column, and lower bending column to rotate upwards by a certain angle, thus bending the steel plate upwards by a certain angle. The plate is then fed by the upper feeding machine... The upper and lower feeding mechanisms drive the steel plate to retract a certain distance, then the rotating connecting plate resets the upper forming column, lower forming column, and lower bending column. The upper and lower feeding mechanisms then continue to convey the steel plate. At this time, the second servo motor drives the connecting plate to rotate downwards at a certain angle, so that the outer wall of the upper forming column fits against the steel plate. After the upper and lower feeding mechanisms convey the steel plate a certain distance, the steel plate is bent into a U-shape. The forming mechanism then forms the steel plate into a clamp. Throughout the process, the operator can support and limit the steel plate, and multiple stamping and bending operations are performed wirelessly, resulting in a one-time forming. This not only simplifies the process but also improves the forming efficiency of the device.
[0019] Furthermore, the drive mechanism includes a second base fixedly connected to the rear end of the top of the unloading platform. The second base is located on the other side of the fixed base. A second servo motor is fixedly connected to the top of the second base. A gear ring is fixedly connected to the center of the outer wall of the third rotating shaft. A gear is fixedly connected to the outer wall of the output shaft of the second servo motor. The gear ring meshes with the gear.
[0020] The above technical solution, through the operation of the drive mechanism, saves time and effort, and the meshing of the gear ring and gear can transmit power and torque to each other, which has the advantages of simple structure, high transmission efficiency and high reliability.
[0021] Furthermore, the limiting mechanism includes a support base fixedly connected to the front end of the top of the unloading platform. A fixed plate is fixedly connected to the rear end of the support base. A limiting ring is rotatably connected to the rear end of the fixed plate. A first limiting groove is formed at the center of the rear end of the limiting ring. A second limiting groove is formed on one side of the first limiting groove at the rear end of the limiting ring. A third limiting groove is formed at the top of the first limiting groove at the rear end of the limiting ring. In the combined state, the front ends of the upper forming column and the lower forming column are slidably connected to the first limiting groove. The front end of the upper forming column is slidably connected to the third limiting groove. The front end of the lower bending column is slidably connected to the second limiting groove.
[0022] With the above technical solution, when the forming mechanism is bending, both the upper forming column and the lower forming column rotate in the first limiting groove, the upper forming column rotates in the third limiting groove, and the lower bending column rotates in the second limiting groove, which plays a certain limiting role and improves the stability of the forming mechanism during operation, thereby improving the quality of steel plate forming.
[0023] The forming method of the power fitting manufacturing forming device includes the following specific steps:
[0024] Step 1: The worker inserts one end of the steel plate into the processing table through the feeding port, and starts the first servo motors in the upper and lower feeding mechanisms. The output shafts of the two first servo motors rotate, driving the connected third synchronous pulleys to rotate, which in turn drives the two connected third synchronous belts to rotate. The other two connected third synchronous pulleys then rotate, driving the corresponding first rotating shafts to rotate. The rotation of the two first rotating shafts drives the connected feeding rollers and second synchronous pulleys to rotate. The rotation of the two second synchronous pulleys drives the connected second synchronous belts to rotate, which in turn drives the other two connected second synchronous pulleys to rotate, which in turn drives the connected second rotating shafts to rotate. This cycle continues, with the rotation of multiple second rotating shafts driving the connected feeding rollers to rotate. At the same time, the output shaft of the first servo motor in the upper feeding mechanism rotates clockwise, and the output shaft of the first servo motor in the lower feeding mechanism rotates counterclockwise, thus conveying the steel plate.
[0025] Step Two: One end of the steel plate is conveyed to the top of the unloading platform via the upper and lower feeding mechanisms and inserted into the gap between the upper and lower forming columns. Simultaneously, it conforms to the inner walls of the upper and lower forming columns. The second servo motor is activated, and its output shaft rotates, driving a gear to rotate. The gear rotates, which in turn rotates a meshing gear ring. The gear ring rotates, which in turn rotates a third rotating shaft fixedly connected to it. The third rotating shaft rotates, causing a connecting disc to rotate. This rotation of the connecting disc causes the upper forming column, lower forming column, and lower bending column to rotate upwards by a certain angle, allowing the steel plate to... The plate is bent upwards at a certain angle, and then the upper and lower feeding mechanisms drive the steel plate to retract a certain distance. Then the connecting plate is rotated to reset the upper forming column, lower forming column, and lower bending column. The upper and lower feeding mechanisms then drive the steel plate to continue to be conveyed. At this time, the second servo motor drives the connecting plate to rotate downwards at a certain angle, so that the outer wall of the upper forming column is in contact with the steel plate. After the upper and lower feeding mechanisms drive the steel plate to be conveyed a certain distance, the steel plate is bent into a U-shape. Then the connecting plate is rotated to reset the upper feeding mechanism, lower feeding mechanism, and upper forming column.
[0026] Step 3: After the upper and lower feeding mechanisms drive the bent steel plate a certain distance, the hydraulic cylinder is activated. The hydraulic cylinder pushes the stamping knife through the piston, which in turn stamps the steel plate. When the bottom of the stamping knife is in contact with the top of the knife holder, the formed steel plate is cut off.
[0027] Step 4: When the hydraulic cylinder is running, the connecting plate connected to the hydraulic cylinder piston moves downward, thereby pushing the two buffer columns connected to it, so that the bottom ends of the two buffer columns squeeze the corresponding buffer springs, thereby achieving a buffering effect on the stamping knife.
[0028] Step 5: The cut and shaped steel plates fall onto the discharge chute. Workers collect the shaped steel plates through the discharge chute. Meanwhile, the remaining steel plates are processed into shape sequentially through the upper feeding mechanism, the lower feeding mechanism, the punching mechanism, and the forming mechanism.
[0029] The beneficial effects of the present invention are as follows: (1) The present invention is designed with a support mechanism, an upper feeding mechanism and a lower feeding mechanism. The width of the steel plate to be processed is the same as the width of the feeding port, which greatly improves the stability of the upper feeding mechanism and the lower feeding mechanism, and thus facilitates the forming mechanism to form it; (2) The present invention is designed with a punching mechanism and a buffer mechanism. The hydraulic cylinder runs automatically to drive the formed steel plate to punch, without the need for manual support and limit by the staff, avoiding accidental injury caused by the machine. At the same time, the buffer mechanism reduces the thrust of the punching knife during punching and improves the service life of the punching knife; (3) The present invention is designed with a forming mechanism, a driving mechanism and a limiting mechanism. The device forms the steel plate into a hoop shape in one go during the whole process, without the need for multiple punching and forming. The process is not only simple, but also has a high forming efficiency. At the same time, the limiting mechanism greatly improves the stability of the forming mechanism, thereby improving the quality of the steel plate forming. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0040] like Figure 1 As shown, an electrical fitting manufacturing and forming apparatus of this embodiment includes a support mechanism 1, which includes a processing table 101. A feeding port 102 is provided on one side of the processing table 101, and a discharging port 103 is provided on the other side of the processing table 101. A unloading platform 104 is fixedly connected to the other side of the processing table 101. A discharge trough 105 is provided on the top of the unloading platform 104. Workers can feed materials through the discharging port 103 and collect the formed steel plates through the discharge trough 105. The whole process is carried out in an orderly manner, which improves the stability of steel plate processing.
[0041] like Figure 4 and 5As shown, the support mechanism 1 is internally equipped with an upper feeding mechanism 2. The upper feeding mechanism 2 includes a first rotating shaft 201 rotatably connected between the inner walls of the front and rear ends of the processing table 101. Multiple second rotating shafts 202 are rotatably connected to the inner walls of the front and rear ends of the processing table 101 at a position located on one side of the first rotating shaft 201. A first synchronous pulley 203 is fixedly connected to the front end of the outer wall of each of the multiple second rotating shafts 202. A first synchronous belt 204 is installed between every two first synchronous pulleys 203. A second synchronous pulley 205 is fixedly connected to the front end of the outer wall of the first rotating shaft 201 and one of the adjacent second rotating shafts 202. A second synchronous belt 206 is installed between the synchronous pulleys 205. Feed rollers 207 are fixedly connected to the center of the outer walls of both the first and second shafts 201 and 202. Fixed sleeves 208 are rotatably connected to the rear ends of the outer walls of both the first and second shafts 201 and 202. The inner walls of multiple fixed sleeves 208 are fixedly connected to the outer wall of the processing table 101. A first machine base 209 is fixedly connected to one side of the top of the processing table 101. A first servo motor 210 is fixedly connected to the top of the first machine base 209. A third synchronous pulley 21 is fixedly connected to the output shaft of the first servo motor 210 and the front end of the outer wall of the first shaft 201. 1. A third synchronous belt 212 is installed between the two third synchronous pulleys 211. When feeding the steel plate to be formed, the first servo motor 210 in the upper feeding mechanism 2 and the lower feeding mechanism 3 is started. The output shafts of the two first servo motors 210 rotate, respectively driving the third synchronous pulleys 211 connected to them to rotate, which in turn drives the two third synchronous belts 212 connected to them to rotate. The other two third synchronous pulleys 211 connected to them rotate accordingly, respectively driving the corresponding first rotating shafts 201 to rotate. The rotation of the two first rotating shafts 201 drives the feeding rollers 207 and the third synchronous belts 212 connected to them to rotate. The two synchronous pulleys 205 rotate, which in turn drives the connected second synchronous belt 206 to rotate, thereby driving the other two connected second synchronous pulleys 205 to rotate, which in turn drives the connected second rotating shaft 202 to rotate. This cycle continues, and the rotation of multiple second rotating shafts 202 drives the connected feeding rollers 207 to rotate. At the same time, the output shaft of the first servo motor 210 in the upper feeding mechanism 2 rotates clockwise, and the output shaft of the first servo motor 210 in the lower feeding mechanism 3 rotates counterclockwise, thereby realizing the conveying of the steel plate to be processed.
[0042] like Figure 2 and 4As shown, the support mechanism 1 is equipped with a lower feeding mechanism 3. The upper feeding mechanism 2 and the lower feeding mechanism 3 have the same structure. The structure of the upper feeding mechanism 2 and the lower feeding mechanism 3 is relatively compact. At the same time, the width of the feeding roller 207 is the same as the width of the steel plate to be processed, and the width of the steel plate to be processed is the same as the width of the feeding port 102. This allows the steel plate to be processed to be stably conveyed within the processing table 101, preventing the steel plate to be processed from shifting and improving the stability and accuracy of the steel plate forming.
[0043] like Figure 6 As shown, a punching mechanism 4 is installed at one end of the support mechanism 1. The punching mechanism 4 includes a support frame 401 fixedly connected to the other side of the top of the processing table 101. A hydraulic cylinder 402 is fixedly connected to the top of the support frame 401. A punching knife 403 is fixedly connected to the bottom end of the piston of the hydraulic cylinder 402. A knife holder 404 is fixedly connected to the other side of the bottom inner surface of the processing table 101. After the steel plate is formed, it needs to be cut off. The cut off part is the formed clamp. The hydraulic cylinder 402 is started. The hydraulic cylinder 402 pushes the punching knife 403 through the piston, thereby making the punching knife 403 punch the steel plate. When the bottom of the punching knife 403 is in contact with the top of the knife holder 404, the formed steel plate is cut off without the need for manual cutting by the operator, thus avoiding accidental injury to the operator caused by the punching mechanism 4.
[0044] like Figure 6 As shown, a buffer mechanism 5 is installed at the bottom of the punching mechanism 4. The buffer mechanism 5 includes two fixed cylinders 501 fixedly connected to the other side of the top of the processing table 101. Buffer springs 502 are fixedly connected inside each of the two fixed cylinders 501. A connecting plate 503 is fixedly connected to the outer wall of the piston of the hydraulic cylinder 402. Two buffer columns 504 are fixedly connected to the bottom of the connecting plate 503. The two buffer columns 504 are slidably connected to the two fixed cylinders 501 respectively. When the hydraulic cylinder 402 is running, the connecting plate 503 connected to the piston of the hydraulic cylinder 402 moves downward, thereby pushing the two buffer columns 504 connected to it. This causes the bottom ends of the two buffer columns 504 to squeeze the corresponding buffer springs 502, thereby achieving a buffering effect on the punching knife 403, preventing excessive pressure from the hydraulic cylinder 402, and avoiding excessive thrust applied to the punching knife 403. This prevents damage when the punching knife 403 punches against the knife holder 404, further improving the service life of the punching knife 403.
[0045] like Figure 2 and 7As shown, a forming mechanism 6 is installed at the rear end of one side of the top of the support mechanism 1. The forming mechanism 6 includes a fixed base 601 fixedly connected to the rear end of the top of the unloading platform 104. A third rotating shaft 602 is rotatably connected to the front end of the fixed base 601. A connecting plate 603 is fixedly connected to the front end of the third rotating shaft 602. An upper forming column 604 is fixedly connected to the front end of the connecting plate 603. A lower forming column 605 is fixedly connected to the front end of the connecting plate 603 near the bottom of the upper forming column 604. A lower bending column 606 is fixedly connected to the front end of the connecting plate 603 near the side of the lower forming column 605. A connecting shaft 607 is fixedly connected to the front end of the connecting plate 603 near the top of the upper forming column 604. An upper bending column 608 is rotatably connected to the outer wall of the connecting shaft 607. When one end of the steel plate is conveyed to the top of the unloading platform 104 via the upper feeding mechanism 2 and the lower feeding mechanism 3 and inserted into the gap between the upper forming column 604 and the lower forming column 605, simultaneously fitting against the inner walls of the upper forming column 604 and the lower forming column 605, the second servo motor 702 is activated. The second servo motor 702 drives the gear 704 to rotate via its output shaft. The rotation of the gear 704... The gear ring 703, which meshes with the steel plate, rotates. The rotation of the gear ring 703 drives the third rotating shaft 602, which is fixedly connected to it, to rotate. The rotation of the third rotating shaft 602 drives the connecting disc 603 to rotate. The rotation of the connecting disc 603 causes the upper forming column 604, the lower forming column 605, and the lower bending column 606 to rotate upwards by a certain angle, thus bending the steel plate upwards by a certain angle. Then, through the upper feeding mechanism 2 and the lower feeding mechanism 3, the steel plate is retracted a certain distance. Finally, the connecting disc 603 rotates back, causing the upper forming column 604, the lower forming column 605, and the lower bending column 606 to repeat the bending process. The steel plate is then conveyed through the upper feeding mechanism 2 and the lower feeding mechanism 3. At this time, the connecting plate 603 is rotated downward by the second servo motor 702, so that the outer wall of the upper forming column 604 is in contact with the steel plate. After the upper feeding mechanism 2 and the lower feeding mechanism 3 convey the steel plate a certain distance, the steel plate is bent into a U-shape. The forming mechanism 6 forms the steel plate into a clamp. Throughout the process, the operator supports and limits the steel plate, and the plate is punched and bent multiple times in one go. This not only simplifies the process but also improves the forming efficiency of the device.
[0046] like Figure 2 , Figure 6 and Figure 7As shown, a drive mechanism 7 is installed on the top of the support mechanism 1 on the other side of the forming mechanism 6. The drive mechanism 7 includes a second base 701 fixedly connected to the rear end of the top of the unloading platform 104. The second base 701 is located on the other side of the fixed base 601. A second servo motor 702 is fixedly connected to the top of the second base 701. A gear ring 703 is fixedly connected to the center of the outer wall of the third rotating shaft 602. A gear 704 is fixedly connected to the outer wall of the output shaft of the second servo motor 702. The gear ring 703 meshes with the gear 704. The drive mechanism 7 runs, saving time and effort. The meshing of the gear ring 703 and the gear 704 can transmit power and torque to each other, which has the advantages of simple structure, high transmission efficiency and strong reliability.
[0047] like Figure 2 and Figure 8 As shown, the top of the support mechanism 1 is fixedly connected to the front end of the forming mechanism 6, and the limiting mechanism 8 includes a support base 801 fixedly connected to the front end of the top of the unloading platform 104. The rear end of the support base 801 is fixedly connected to a fixing plate 802. The rear end of the fixing plate 802 is rotatably connected to a limiting ring 803. A first limiting groove 804 is formed at the center of the rear end of the limiting ring 803. A second limiting groove 805 is formed on one side of the first limiting groove 804 at the rear end of the limiting ring 803. A third limiting groove 806 is formed at the top of the first limiting groove 804 at the rear end of the limiting ring 803. In the combined state... The front ends of the upper forming column 604 and the lower forming column 605 are slidably connected to the first limiting groove 804, the front end of the upper forming column 604 is slidably connected to the third limiting groove 806, and the front end of the lower bending column 606 is slidably connected to the second limiting groove 805. When the forming mechanism 6 bends, both the upper forming column 604 and the lower forming column 605 rotate within the first limiting groove 804, the upper forming column 604 rotates within the third limiting groove 806, and the lower bending column 606 rotates within the second limiting groove 805, which plays a certain limiting role and improves the stability of the forming mechanism 6 during operation, thereby improving the quality of steel plate forming.
[0048] The forming method of the power fitting manufacturing forming device includes the following specific steps:
[0049] Step 1: The worker inserts one end of the steel plate into the processing table 101 through the feeding port 102, and starts the first servo motor 210 in the upper feeding mechanism 2 and the lower feeding mechanism 3. The output shafts of the two first servo motors 210 rotate, driving the third synchronous pulley 211 connected to them to rotate, which in turn drives the two third synchronous belts 212 connected to them to rotate. The other two third synchronous pulleys 211 connected to them rotate accordingly, driving the corresponding first rotating shaft 201 to rotate. The rotation of the two first rotating shafts 201 drives the feeding roller 207 and the second synchronous belt 207 connected to them to rotate. The step wheel 205 rotates, and the rotation of the two second synchronous wheels 205 drives the second synchronous belt 206 connected to it to rotate, thereby driving the other two second synchronous wheels 205 connected to it to rotate, which in turn drives the second rotating shaft 202 connected to it to rotate. This cycle continues, and the rotation of multiple second rotating shafts 202 drives the feeding roller 207 connected to them to rotate. At the same time, the output shaft of the first servo motor 210 in the upper feeding mechanism 2 rotates clockwise, and the output shaft of the first servo motor 210 in the lower feeding mechanism 3 rotates counterclockwise, thereby realizing the conveying of the steel plate.
[0050] Step Two: One end of the steel plate is conveyed to the top of the unloading platform 104 via the upper feeding mechanism 2 and the lower feeding mechanism 3, and inserted into the gap between the upper forming column 604 and the lower forming column 605. Simultaneously, it adheres to the inner walls of the upper forming column 604 and the lower forming column 605. The second servo motor 702 is activated, and its output shaft rotates to drive the gear 704. The gear 704 rotates, driving the meshing gear ring 703 to rotate. The gear ring 703 rotates, driving the fixedly connected third rotating shaft 602 to rotate. The third rotating shaft 602 rotates, driving the connecting plate 603 to rotate. The rotation of the connecting plate 603 causes the upper forming column 604, the lower forming column 605, and the lower bending column 606 to rotate upwards. The steel plate is bent upwards at a certain angle, and then the upper feeding mechanism 2 and the lower feeding mechanism 3 drive the steel plate to retract a certain distance. Then the connecting plate 603 is rotated to reset the upper forming column 604, the lower forming column 605 and the lower bending column 606. The upper feeding mechanism 2 and the lower feeding mechanism 3 drive the steel plate to continue to be conveyed. At this time, the second servo motor 702 drives the connecting plate 603 to rotate downwards at a certain angle, so that the outer wall of the upper forming column 604 is in contact with the steel plate. After the upper feeding mechanism 2 and the lower feeding mechanism 3 drive the steel plate to be conveyed a certain distance, the steel plate is bent into a U-shape. Then the connecting plate 603 is rotated to reset the upper feeding mechanism 2, the lower feeding mechanism 3 and the upper forming column 604.
[0051] Step 3: After the upper feeding mechanism 2 and the lower feeding mechanism 3 drive the bent steel plate to travel a certain distance, the hydraulic cylinder 402 is activated. The hydraulic cylinder 402 pushes the stamping knife 403 through the piston, thereby allowing the stamping knife 403 to stamp the steel plate. When the bottom of the stamping knife 403 is in contact with the top of the knife holder 404, the formed steel plate is cut off.
[0052] Step 4: When the hydraulic cylinder 402 is running, the connecting plate 503 connected to the piston of the hydraulic cylinder 402 moves downward, thereby pushing the two buffer columns 504 connected to it, so that the bottom ends of the two buffer columns 504 respectively squeeze the corresponding buffer springs 502, thereby achieving a buffering effect on the punching knife 403.
[0053] Step 5: The cut and shaped steel plate falls onto the discharge chute 105. The workers collect the shaped steel plate through the discharge chute 105. At the same time, the remaining steel plate is processed into shape by the upper feeding mechanism 2, the lower feeding mechanism 3, the punching mechanism 4 and the forming mechanism 6 in sequence.

8. The forming method of the power fitting manufacturing forming apparatus according to claim 7, comprising the following specific steps: Step 1: The worker inserts one end of the steel plate into the processing table (101) through the feeding port (102), and starts the first servo motor (210) in the upper feeding mechanism (2) and the lower feeding mechanism (3). The output shafts of the two first servo motors (210) rotate, respectively driving the third synchronous pulley (211) connected to them to rotate, which in turn drives the two third synchronous belts (212) connected to them to rotate. The other two third synchronous pulleys (211) connected to them rotate accordingly, respectively driving the corresponding first rotating shaft (201) to rotate. The rotation of the two first rotating shafts (201) drives the feeding roller (207) and the second feeding roller (207) connected to them to rotate. The synchronous pulley (205) rotates, and the rotation of the two second synchronous pulleys (205) drives the second synchronous belt (206) connected to it to rotate, thereby driving the other two second synchronous pulleys (205) connected to it to rotate, and then driving the second rotating shaft (202) connected to it to rotate. In this cycle, the rotation of multiple second rotating shafts (202) drives the feeding roller (207) connected to them to rotate. At the same time, the output shaft of the first servo motor (210) in the upper feeding mechanism (2) rotates clockwise, and the output shaft of the first servo motor (210) in the lower feeding mechanism (3) rotates counterclockwise, thereby realizing the conveying of the steel plate. Step 2: One end of the steel plate is conveyed to the top of the unloading platform (104) through the upper feeding mechanism (2) and the lower feeding mechanism (3) and inserted into the gap between the upper forming column (604) and the lower forming column (605). At the same time, it fits against the inner wall of the upper forming column (604) and the lower forming column (605). The second servo motor (702) is started. The second servo motor (702) drives the gear (704) to rotate through the output shaft. The gear (704) rotates and drives the gear ring (703) that meshes with it to rotate. The gear ring (703) rotates and drives the third rotating shaft (602) that is fixedly connected to it to rotate. The third rotating shaft (602) rotates and drives the connecting plate (603) to rotate. The connecting plate (603) rotates and thus drives the upper forming column (604), the lower forming column (605) and the lower bending column (606). Rotate upwards at a certain angle to bend the steel plate upwards at a certain angle. Then, the upper feeding mechanism (2) and the lower feeding mechanism (3) drive the steel plate to retract a certain distance. Then, rotate the connecting plate (603) to reset the upper forming column (604), the lower forming column (605), and the lower bending column (606). Then, the upper feeding mechanism (2) and the lower feeding mechanism (3) drive the steel plate to continue to be conveyed. At this time, the second servo motor (702) drives the connecting plate (603) to rotate downwards at a certain angle so that the outer wall of the upper forming column (604) is in contact with the steel plate. After the upper feeding mechanism (2) and the lower feeding mechanism (3) drive the steel plate to be conveyed a certain distance, the steel plate is bent into a U-shape. Then, rotate the connecting plate (603) to reset the upper feeding mechanism (2), the lower feeding mechanism (3), and the upper forming column (604). Step 3: After the upper feeding mechanism (2) and the lower feeding mechanism (3) drive the bent steel plate to travel a certain distance, start the hydraulic cylinder (402). The hydraulic cylinder (402) pushes the stamping knife (403) through the piston, and then the stamping knife (403) stamps the steel plate. When the bottom of the stamping knife (403) is in contact with the top of the knife holder (404), the formed steel plate is cut off. Step 4: When the hydraulic cylinder (402) is running, the connecting plate (503) connected to the piston of the hydraulic cylinder (402) moves downward, thereby pushing the two buffer columns (504) connected to it, so that the bottom ends of the two buffer columns (504) respectively squeeze the corresponding buffer springs (502), thereby achieving a buffering effect on the stamping knife (403); Step 5: The cut-off steel plate falls onto the discharge chute (105). The workers collect the cut-off steel plate through the discharge chute (105). Meanwhile, the remaining steel plate is processed into shape by the upper feeding mechanism (2), the lower feeding mechanism (3), the punching mechanism (4), and the forming mechanism (6) in sequence.
