Description

Technical Field

[0001] This utility model relates to the field of bending equipment technology, specifically to an automatic bending equipment for insulating side plates. Background Technology

[0002] Insulating side panels are sheet materials used for electrical insulation, typically made of adhesive insulating materials. They provide protection against electric shock. The core material of the insulating side panel is adhesive insulating material, with insulating layers covering the upper and lower surfaces, and an irregular internal structure. Depending on the voltage level, their thickness, color, and specifications vary. Before use, insulating side panels need to be bent. Traditionally, this involves using a stamping machine to press and bend the insulating side panels, followed by manual removal. This method carries a high risk, and the hardness of the insulating side panel material varies. Bending harder materials can easily produce flying debris that can cause injury. To address these issues, an automatic bending device for insulating side panels is proposed.

[0003] For example, the transformer production insulation material bending machine disclosed in the authorization announcement number CN218447558U includes a bending device. Movable rotating plates are rotatably installed on both sides of the inner wall of the bending device via rotating shafts. An elastic heat-resistant plate is installed between the two movable rotating plates. A motor frame is welded to the middle of the front face of the bending device. A drive gear is rotatably installed on the middle of one end of the inner wall of the motor frame. A motor is installed inside the motor frame at one end of the drive gear. A driven gear is installed inside the motor frame through the rotating shaft of the movable rotating plate, which passes through the outside of the bending device. Fixed slide grooves are opened at the middle of both the front and rear ends of the inner wall of the bending device. An installation frame is movably installed inside the fixed slide groove. Although it achieves the effect of facilitating the heating and softening of the outer surface of harder insulating materials, it improves the bending effect of some harder insulating materials, avoids the possibility of the insulating material breaking during the bending process, and improves the overall bending efficiency of the insulating material. However, this does not solve the problem that existing bending equipment is not conducive to the simultaneous ejection of the bent insulating side plate during use, nor to the automatic removal of the finished insulating side plate, which affects the safety of use. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic bending device for insulating side plates, so as to solve the problem mentioned in the background art that the bending device is not convenient for linking and ejecting the bent insulating side plate, which is not conducive to the automatic removal of the finished insulating side plate and affects the safety of use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic bending device for insulating side panels, comprising a base and connecting columns. Two sets of connecting columns are symmetrically arranged at the top of the base. A top plate is provided above the base and connected to the connecting columns. A lower mold base is provided at the center of the top of the base. Multiple sets of L-shaped grooves with equal spacing are provided inside the lower mold base. Threaded rods are movably installed at the top of each L-shaped groove. Gears are fixedly installed on the surface of each threaded rod. Threaded sleeves are provided on the surface of each threaded rod above the gears and are threadedly connected to the threaded rods. Lifting sleeves are provided on the surface of each threaded sleeve and are slidably connected to the L-shaped grooves. Multiple sets of second cylinders with equal spacing are provided on the outer wall of the lower mold base. A third push arm is installed at the output end of each second cylinder. A rack is provided at the end of each third push arm away from the second cylinder and is slidably connected to the lower mold base. The rack and gear mesh with each other.

[0006] Preferably, a hydraulic cylinder is provided at the top of the top plate, and a second push arm is installed at the output end of the hydraulic cylinder.

[0007] Preferably, an upper mold base is installed at the bottom end of the second push arm, and the upper mold base is slidably connected to the connecting column.

[0008] Preferably, a protective cover is provided on the outer wall of the upper mold base, and a telescopic cover is slidably provided inside the protective cover.

[0009] Preferably, the top of the telescopic cover is provided with multiple sets of springs at equal intervals, and the springs are connected to the protective cover.

[0010] Preferably, a transverse lead screw moving mechanism is provided on one side of the base, and a servo motor is provided at the power output end of the transverse lead screw moving mechanism.

[0011] Preferably, the power output end of the servo motor is provided with a vertical lead screw moving mechanism, and the power output end of the vertical lead screw moving mechanism is provided with a placement frame.

[0012] Preferably, a first cylinder is provided on the side wall of the placement rack, a first push arm is installed at the output end of the first cylinder, and a suction cup is provided at the end of the first push arm away from the first cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this bending equipment not only realizes the linkage ejection of the bent insulating side plate, facilitating the automatic removal of the finished insulating side plate, but also improves the safety of use. (1) The insulating side plate is placed on the lower mold base. The hydraulic cylinder drives the upper mold base to move downward through the second push arm. With the cooperation of the lower mold base, the upper mold base and the lower mold base bend the insulating side plate. After bending, the second cylinder drives the rack to move through the third push arm. The rack drives the gear to rotate. The gear drives the threaded rod to rotate. The threaded rod drives the lifting sleeve to move upward through the threaded sleeve. Multiple sets of lifting sleeves move upward synchronously and push the insulating side plate out of the lower mold base to avoid the insulating side plate getting stuck in the lower mold base. The horizontal screw moving mechanism drives the servo motor and the vertical screw moving mechanism to move. The vertical screw moving mechanism drives the placement frame, the first cylinder and the suction cup frame to move, so that the suction cup frame moves to the corresponding height. The first cylinder drives the placement frame, the first cylinder and the suction cup frame to move. The cylinder drives the first push arm to move, which in turn moves the suction cup frame above the insulating side plate. The vertical screw moving mechanism then moves the suction cup frame downward, causing it to adhere to the surface of the insulating side plate and hold it in place. Afterward, the first cylinder, the vertical screw moving mechanism, and the horizontal screw moving mechanism are reset, and the bent insulating side plate is removed from the lower mold base to the outside of the base. When it is necessary to adjust the stacking position of the insulating side plate, the servo motor drives the suction cup frame and the insulating side plate to rotate, thus adjusting the stacking position of the insulating side plate. This achieves the linkage ejection of the bent insulating side plate, preventing the insulating side plate from getting stuck in the mold and facilitating the automatic removal of the finished insulating side plate, avoiding manual material handling.

[0014] (2) The upper mold base drives the protective cover and telescopic cover to move downward. The telescopic cover first contacts the surface of the base. Under the continuous downward pressure of the protective cover, the telescopic cover squeezes the spring and causes the telescopic cover to retract into the interior of the protective cover. The advantage of this design is to avoid the protective cover rigidly contacting the base, which would cause damage to the protective cover. The telescopic cover and the protective cover cover the lower mold base and the insulating side plate to prevent the side plate from cracking and flying debris from injuring people when bending the insulating side plate, thereby improving its safety.

Two sets of connecting columns 2 are symmetrically arranged at the top of the base 1. A top plate 3 is arranged above the base 1 and connected to the connecting columns 2. A lower mold base 5 is arranged at the center of the top of the base 1. Multiple sets of L-shaped grooves 20 with equal spacing are arranged inside the lower mold base 5. A threaded rod 22 is movably installed at the top of each L-shaped groove 20. Gears 21 are fixedly installed on the surface of each threaded rod 22. The surface of the threaded rod 22 above the gears 21 is provided with… A threaded sleeve 24 is provided, and the threaded sleeve 24 is threadedly connected to the threaded rod 22. The surface of the threaded sleeve 24 is provided with a lifting sleeve 23, and the lifting sleeve 23 is slidably connected to the L-shaped groove 20. Multiple sets of second cylinders 17 with equal spacing are provided on the outer wall of the lower mold base 5. The second cylinders 17 play the role of power drive. A third push arm 18 is installed at the output end of each second cylinder 17. A rack 19 is provided at the end of the third push arm 18 away from the second cylinder 17. The rack 19 is slidably connected to the lower mold base 5, and the rack 19 meshes with the gear 21. A hydraulic cylinder 4 is provided at the top of the top plate 3.

An upper mold base 13 is installed at the bottom end of the second push arm 12, and the upper mold base 13 is slidably connected to the connecting column 2. The insulating side plate is placed on the lower mold base 5. The hydraulic cylinder 4 is opened. With the upper mold base 13 and connecting column 2 sliding together, the hydraulic cylinder 4 drives the upper mold base 13 downwards via the second push arm 12. With the cooperation of the lower mold base 5, the upper mold base 13 and lower mold base 5 bend the insulating side plate. After bending, the second cylinder 17 is opened. The second cylinder 17 drives the rack 19 to move via the third push arm 18. With the rack 19 meshing with the gear 21, the rack 19 drives the gear 21 to rotate. Wheel 21 drives threaded rod 22 to rotate. With the threaded connection between threaded rod 22 and threaded sleeve 24, and the sliding engagement between lifting sleeve 23 and L-shaped groove 20, threaded rod 22 drives lifting sleeve 23 to move upward through threaded sleeve 24. Multiple sets of lifting sleeves 23 move upward synchronously and push the insulating side plate out of the lower mold base 5, preventing the insulating side plate from getting stuck in the lower mold base 5. Then, the horizontal lead screw moving mechanism 6 and the vertical lead screw moving mechanism 25 are opened. The horizontal lead screw moving mechanism 6 drives servo motor 7 and vertical lead screw moving mechanism 25. The lever moving mechanism 25 moves, driving the placement frame 8, the first cylinder 9, and the suction cup frame 11 to move, so that the suction cup frame 11 moves to the corresponding height. Then, the first cylinder 9 is opened, driving the first push arm 10 to move, which in turn drives the suction cup frame 11 to move above the insulating side plate. The vertical screw moving mechanism 25 then drives the suction cup frame 11 downward, so that the suction cup frame 11 adheres to the surface of the insulating side plate and adheres to it. After that, the first cylinder 9 and the vertical screw moving mechanism 25 are operated to move the placement frame 8, the first cylinder 9, and the suction cup frame 11 to the corresponding height. The lead screw moving mechanism 25 and the transverse lead screw moving mechanism 6 are reset, and the bent insulating side plate is taken out from the lower mold base 5 to the outside of the base 1. When it is necessary to adjust the stacking position of the insulating side plate, the servo motor 7 is turned on. The servo motor 7 drives the suction cup frame 11 and the insulating side plate to rotate, which can adjust the stacking position of the insulating side plate. This realizes the linkage ejection of the bent insulating side plate, preventing the insulating side plate from getting stuck in the mold, and facilitating the automatic removal of the finished insulating side plate, avoiding the need for manual material handling. A protective cover 14 is provided on the outer wall of the upper mold base 13. A telescopic cover 16 is slidably provided inside the protective cover 14. Multiple sets of springs 15 with equal spacing are provided at the top of the telescopic cover 16, and the springs 15 are connected to the protective cover 14. A transverse lead screw moving mechanism 6 is provided on one side of the base 1. A servo motor 7 is provided at the power output end of the transverse lead screw moving mechanism 6. The servo motor 7 plays the role of power drive. The power output end of the servo motor 7 is provided with a vertical lead screw moving mechanism 25, the power output end of the vertical lead screw moving mechanism 25 is provided with a placement frame 8, the side wall of the placement frame 8 is provided with a first cylinder 9, the first cylinder 9 plays the role of power driving, the output end of the first cylinder 9 is equipped with a first push arm 10, and the end of the first push arm 10 away from the first cylinder 9 is provided with a suction cup frame 11. During the downward pressing of the upper mold base 13, the upper mold base 13 drives the protective cover 14 and the telescopic cover 16 to move downward. The telescopic cover 16 first contacts the surface of the base 1. Under the continuous downward pressing of the protective cover 14, the telescopic cover 16 squeezes the spring 15 and causes the telescopic cover 16 to retract into the interior of the protective cover 14. The advantage of this design is that it avoids the protective cover 14 from rigidly contacting the base 1, thereby preventing damage to the protective cover 14. The telescopic cover 16 and the protective cover 14 cover the lower mold base 5 and the insulating side plate to prevent the side plate from cracking and splintering when bending the insulating side plate, thus improving its safety during use.

[0021] Work steps The insulating side plate is placed on the lower mold base 5. The hydraulic cylinder 4 drives the upper mold base 13 to move downward through the second push arm 12. With the cooperation of the lower mold base 5, the upper mold base 13 and the lower mold base 5 bend the insulating side plate. After bending, the second cylinder 17 drives the rack 19 to move through the third push arm 18. The rack 19 drives the gear 21 to rotate. The gear 21 drives the threaded rod 22 to rotate. The threaded rod 22 drives the lifting sleeve 23 to move upward through the threaded sleeve 24. Multiple sets of lifting sleeves 23 move upward synchronously. The mechanism moves upward and pushes the insulating side plate out of the lower mold base 5 to prevent it from getting stuck inside. The horizontal lead screw moving mechanism 6 drives the servo motor 7 and the vertical lead screw moving mechanism 25 to move. The vertical lead screw moving mechanism 25 then drives the placement frame 8, the first cylinder 9, and the suction cup frame 11 to move to the corresponding height. The first cylinder 9 then drives the first push arm 10 to move, which in turn moves the suction cup frame 11 above the insulating side plate. Finally, the vertical lead screw moving mechanism 25 drives the suction cup frame 11... The suction cup holder 11 is moved downwards to adhere to the surface of the insulating side plate and hold it in place. Then, the first cylinder 9, the vertical lead screw moving mechanism 25, and the horizontal lead screw moving mechanism 6 are reset, removing the bent insulating side plate from the lower mold base 5 to the outside of the base 1. When the stacking position of the insulating side plates needs to be adjusted, the servo motor 7 drives the suction cup holder 11 and the insulating side plate to rotate, thus adjusting the stacking position. During the downward pressing of the upper mold base 13, the upper mold base 13 drives the protective cover 14 and the extension... The telescopic cover 16 moves downwards and first contacts the surface of the base 1. Under the continuous downward pressure of the protective cover 14, the telescopic cover 16 compresses the spring 15 and retracts into the interior of the protective cover 14. The advantage of this design is that it avoids the protective cover 14 from rigidly contacting the base 1, which would cause damage to the protective cover 14.
