Description

Technical Field

[0001] The invention relates to the field of plate bending processing equipment, in particular to a plate bending device for processing a box-type power distribution cabinet. Background Art

[0002] With the continuous development of the electrical industry, the demand for box-type distribution cabinets is growing. In the production process of box-type distribution cabinets, sheet bending is a key link. Traditional sheet bending devices often have many problems and are difficult to meet the needs of modern production.

[0003] On the one hand, in traditional bending devices, it is difficult to position and align the plate, which can easily lead to inaccurate bending positions, thus affecting the bending quality. Due to the lack of effective positioning and alignment mechanisms, operators need to spend a lot of time and energy to make adjustments, which not only reduces production efficiency but also increases the possibility of human error.

[0004] On the other hand, the traditional device is not accurate enough in controlling the bending length. Usually, it can only make rough adjustments based on experience, and it is difficult to achieve accurate control of the bending length each time. This makes the produced box-type distribution cabinets have large differences in dimensional accuracy, affecting the overall quality and assembly accuracy of the product.

[0005] In addition, when bending the side of the plate, the traditional device often cannot effectively adapt to the plate that has been bent. It is easy to damage the bent part during the bending process, or it is impossible to accurately bend different edges, which limits the design diversity and production flexibility of the box-type distribution cabinet.

[0006] In summary, in order to improve the production quality and efficiency of box-type distribution cabinets and meet the needs of the modern electrical industry for high-precision and diversified products, a new type of plate bending device for box-type distribution cabinet processing is urgently needed. Summary of the invention

[0013] Preferably, a second gear is installed on the right side of the interior of the extension frame through a movable shaft and the second gear is meshingly connected to the inner end of the first gear, and a positioning baffle is movably installed on the middle part of the extension frame through two guide rods, and the bottom end of the positioning baffle is fixedly connected to the second rack plate and the second rack plate is meshingly connected to the inner end of the second gear.

[0014] Preferably, a vertical linear motion module is fixedly installed on the inner left side of the workbench, a movable seat is installed on the driving end of the vertical linear motion module, a cross frame is fixedly installed on the upper right end of the movable seat, a slide is movably installed inside the cross frame, a telescopic cylinder is fixedly installed on the inner left side of the cross frame and the driving end of the telescopic cylinder is fixedly connected to one side of the slide, a second motor is fixedly installed on the top of the slide, and the driving end of the second motor passes through the interior of the slide and is fixedly installed with a presser foot through a movable shaft.

[0015] Preferably, a mounting plate is fixedly connected to the lower side of the right end of the movable seat, and a slide is movably mounted on the front and rear sides of the top end of the mounting plate through guide rails, two straight slots are opened on both sides of the interior of the placement table, and clamps are fixedly connected to both sides of the top end of the slide and the ends of the clamps pass through the interior of the straight slots on the corresponding sides and extend above them.

[0016] Preferably, a third motor is fixedly installed in the middle of the bottom end of the mounting plate, the driving end of the third motor passes through the interior of the mounting plate and a turntable is fixedly installed, connecting rods are movably installed on both sides of the top end of the turntable, and the ends of the connecting rods are movably installed in the middle of the inner end of the slide on the corresponding side.

[0017] Working principle: first, place the plate to be bent on the placement table, and then use the vertical linear motion module to control the movable seat to rise. When the movable seat rises, it will drive the cross frame and the mounting plate to rise together. When the mounting plate rises, it will drive the clamps on both sides of the slide to rise, so that the top of the clamp passes through the straight slot, and then start the third motor, and drive the turntable to rotate through the third motor. The rotating turntable will drive the inner ends of the two connecting rods to move inward, thereby pulling the two slides to move inward at the same time, and then drive the four clamps to move inward at the same time, and straighten the plate placed on the placement table to improve the quality of later bending. Then the vertical linear motion module controls the movable seat to descend, driving the cross frame and the mounting plate to descend together. When the mounting plate descends, it will drive the clamps to descend below the straight slot to prevent the later plate from being damaged. The position change of the material is affected, and when the horizontal frame descends, it will drive the presser foot to descend, so that the presser foot contacts and presses the upper surface of the plate. At the same time, since a plurality of balls are movably arranged on the surface of the placing table, when the presser foot moves, it will drive the plate to move together and will not cause wear to the bottom surface of the plate. Then the first hydraulic cylinder is started. The first hydraulic cylinder first controls the movable frame to rise. The rising movable frame will drive the first rack plate to rise together. The rising first rack plate meshes with the first gear to drive the first gear to rotate. The first gear then meshes with the second gear to drive the second gear to rotate. The rotating second gear meshes with the second rack plate to drive the positioning baffle to move left to make it close to the pad platform. The positioning baffle and the pad are controlled by controlling the rising distance of the movable frame. The distance between the platforms is controlled to control the length of each bending. After the distance adjustment is completed, the sliding table is driven to move to the left by the telescopic cylinder, thereby driving the presser foot and the plate to follow the movement. When the right side of the plate moves to the pad and the end hits the left end of the positioning baffle, it indicates that the bending position of the plate is determined. Then the first hydraulic cylinder controls the movable frame to descend. When the movable frame descends, the positioning baffle is driven to move right through the transmission action of the first rack plate, the first gear, the second gear and the second rack plate until the clamping block is pressed on the surface of the plate. At this time, the positioning baffle is completely away from the plate. Then the second hydraulic cylinder is started, and the bending plate is driven to rise by the second hydraulic cylinder to realize the bending of the plate. When it is necessary to bend the side of the plate, the telescopic cylinder is used to control the presser foot and the plate Return to the middle of the placement table, and then use the second motor to drive the presser foot to rotate. The presser foot will drive the plate to rotate with it. The ball bearings on the surface of the placement table can reduce the friction damage caused by the rotation of the plate. After the rotation is completed, the plate is sent to the pad again and the bending distance is controlled. Since both sides of the plate have been bent, it is necessary to start the first motor at this time. The worm is driven by the first motor to rotate. The rotating worm and the worm gear are meshed and driven to drive the worm gear and the coarse shaft to rotate together. When the coarse shaft rotates, it will drive the arc chutes on both sides to rotate together. The rotating arc chutes will drive the round head pin to move, and use the limiting effect of the fixed light rod to drive all the clamping blocks to move together. Since the pitch of the arc chutes increases from the inside to the outside, all the clamping blocks will move inward at the same distance at the same time.At this time, when the first hydraulic cylinder controls the movable frame to descend, the clamping block cannot touch the side of the plate that has been bent, and then the bending work can be started normally. After the bending of all edges of the plate is completed, all parts are controlled to reset and the plate can be removed from the placement table.

[0018] The present invention provides a plate bending device for processing a box-type power distribution cabinet. It has the following beneficial effects:

[0019] 1. The present invention can align the plate placed on the placing table by providing a lifting clamping plate, ensuring the accurate position of the plate during the bending process, thereby improving the bending quality in the later stage. A number of balls are evenly and movably installed on the surface of the placing table. When the presser foot drives the plate to move, it will not cause wear to the bottom surface of the plate, thereby ensuring the integrity of the plate surface and further improving the bending quality.

[0020] 2. When the movable frame of the present invention rises, the first rack plate, the first gear, the second gear and the second rack plate drive the positioning baffle plate to move leftward and close to the pad, and the distance between the positioning baffle plate and the pad can be accurately controlled by controlling the rising distance of the movable frame, thereby accurately controlling the length of each bending;

[0021] 3. When the present invention needs to bend the side of the plate, the first motor can be used to drive the worm to rotate, driving the worm wheel and the thick rotating shaft to rotate, so that the arc-shaped slide groove drives the round head pin to move, and then drives all the clamping blocks to move inward at equal distances at the same time, avoiding the clamping blocks from contacting the side of the plate that has been bent, and can adapt to the bending requirements of different edges of the plate.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Please refer to the attached Figure 1 -Attached Figure 7 The embodiment of the present invention provides a plate bending device for processing a box-type power distribution cabinet, such as Figure 1As shown, it includes a workbench 1, a movable frame 2 is movably installed in the middle of the right end of the workbench 1, and the movable frame 2 can perform specific movements on the workbench 1 to provide support for subsequent bending operations. A rectangular through groove 3 is opened on the inner upper side of the movable frame 2, and the rectangular through groove 3 provides installation space for various internal components. Two fixed light rods 4 are fixedly connected to the inner upper side of the rectangular through groove 3, and the fixed light rods 4 play a role of limiting and guiding. A number of sliding blocks 5 are movably installed on both sides of the interior of the fixed light rod 4, and the sliding blocks 5 can be flexibly moved on the fixed light rod 4. A clamping block 6 is fixedly installed on the bottom end of the sliding block 5, and the clamping block 6 plays a role of clamping the plate during the bending process. A coarse rotating shaft 7 is movably installed at the upper position of the inner part of the rectangular through groove 3 near the fixed light rod 4, and the coarse rotating shaft 7 can To perform rotational motion, a plurality of arc-shaped grooves 8 are provided on the outer diameters of both sides of the coarse rotating shaft 7, and the pitch of the arc-shaped grooves 8 increases from the inside to the outside. This special design enables the sliding block 5 and the clamping block 6 to move equidistantly inward and outward when the coarse rotating shaft 7 rotates. The top ends of the sliding blocks 5 are fixedly connected with round-headed pins 12, and the top ends of the round-headed pins 12 are movably connected to the inside of the corresponding side arc-shaped grooves 8. The cooperation between the round-headed pins 12 and the arc-shaped grooves 8 realizes the motion transmission of the sliding block 5. A placing table 26 is fixedly connected to the middle part of the top end of the workbench 1. The placing table 26 is used to place the plate to be bent. A plurality of balls 27 are evenly and movably installed on the upper surface of the placing table 26. The balls 27 can reduce the friction between the plate and the placing table 26 during movement, thereby protecting the surface of the plate.

[0032] In this embodiment, the two sides of the upper right end of the workbench 1 are respectively fixedly connected to the two ends of the support plate 16, and the support plate 16 provides stable support for the upper components. A second hydraulic cylinder 17 is fixedly installed in the middle of the top end of the support plate 16. The second hydraulic cylinder 17 can provide a strong driving force. A bending plate 18 is fixedly installed at the top driving end of the second hydraulic cylinder 17. The bending plate 18 realizes the bending operation of the plate under the drive of the second hydraulic cylinder 17.

[0033] Furthermore, a worm wheel 9 is fixedly mounted on the middle outer diameter of the coarse rotating shaft 7, and the worm wheel 9 is used to cooperate with the worm 11 to realize transmission. A first motor 10 is fixedly mounted on the middle of the top end of the movable frame 2, and the first motor 10 provides a power source for the entire device. The driving end of the first motor 10 is fixedly mounted with the worm 11, and the worm 11 and the inner end of the worm wheel 9 are meshed and connected. The worm 11 is driven to rotate by the first motor 10, thereby driving the worm wheel 9 and the coarse rotating shaft 7 to rotate.

[0034] Specifically, when it is necessary to bend the side of the plate, the telescopic cylinder 33 is used to control the presser foot 35 and the plate to return to the middle of the placement table 26, and then the second motor 34 is used to drive the presser foot 35 to rotate. The presser foot 35 will drive the plate to rotate. The ball 27 on the surface of the placement table 26 can reduce the friction damage caused by the rotation of the plate. After the rotation is completed, the plate is sent to the pad 15 again and the bending distance is controlled. Since the two sides of the plate have been bent, the first motor 10 needs to be started at this time. The worm 11 is driven to rotate by the first motor 10, and the rotating worm 11 and the worm wheel 9 meshes and drives the worm gear 9 and the coarse shaft 7 to rotate together. When the coarse shaft 7 rotates, the arc-shaped slide grooves 8 on both sides will be driven to rotate together. The rotating arc-shaped slide grooves 8 will drive the round head pin 12 to move, and the limiting effect of the fixed light rod 4 will be utilized to drive all the clamping blocks 6 to move together. Since the pitch of the arc-shaped slide grooves 8 increases from the inside to the outside, all the clamping blocks 6 will move inward at the same distance at the same time. At this time, when the movable frame 2 is controlled to descend by the first hydraulic cylinder 14, the clamping blocks 6 will not be able to contact the side of the plate that has been bent, and then the bending work can be started normally.

[0035] Furthermore, a gantry 13 is fixedly connected to the right side of the top of the workbench 1, and the gantry 13 provides an installation position for the first hydraulic cylinder 14 above. The first hydraulic cylinders 14 are fixedly installed on both sides of the top of the gantry 13. The first hydraulic cylinders 14 can control the lifting and lowering movement of the movable frame 2. The driving ends of the first hydraulic cylinders 14 pass through the top wall of the gantry 13 and are respectively fixedly installed on both sides of the top of the movable frame 2. The rising and lowering of the movable frame 2 is achieved by the extension and retraction of the first hydraulic cylinder 14. A pad 15 is fixedly connected to the right side of the top of the workbench 1 near the inner middle position of the rectangular through groove 3. The pad 15 plays a role of supporting the plate during the bending process.

[0036] Furthermore, a first rack plate 19 is fixedly connected to the lower side of the right end of the movable frame 2, and the first rack plate 19 is used to mesh with the first gear 21 for transmission. The two sides of the middle of the right end of the workbench 1 are respectively fixedly connected to the two ends of the extension frame 20. The extension frame 20 provides installation support for each gear inside. The first gear 21 is installed on the left side of the interior of the extension frame 20 through a movable shaft, and the first gear 21 is meshed with the inner end of the first rack plate 19. The movement of the first rack plate 19 can drive the first gear 21 to rotate.

[0037] Furthermore, a second gear 22 is installed on the right side of the interior of the extension frame 20 through a movable shaft, and the second gear 22 is meshed with the inner end of the first gear 21. The rotation of the first gear 21 can drive the second gear 22 to rotate. A positioning baffle 24 is movably installed on the middle part of the extension frame 20 through two guide rods 23. The positioning baffle 24 can position the plate. The bottom end of the positioning baffle 24 is fixedly connected with a second rack plate 25, and the second rack plate 25 is meshed with the inner end of the second gear 22. The rotation of the second gear 22 can drive the second rack plate 25 and the positioning baffle 24 to move.

[0038] Specifically, the first hydraulic cylinder 14 is started, and the first hydraulic cylinder 14 first controls the movable frame 2 to rise. The rising movable frame 2 will drive the first rack plate 19 to rise together. The rising first rack plate 19 meshes with the first gear 21 to drive the first gear 21 to rotate. The first gear 21 then meshes with the second gear 22 to drive the second gear 22 to rotate. The rotating second gear 22 meshes with the second rack plate 25 to drive the positioning baffle 24 to move leftward to make it close to the pad 15. The distance between the positioning baffle 24 and the pad 15 is controlled by controlling the rising distance of the movable frame 2, thereby controlling the length of each bending. After the distance adjustment is completed, the positioning baffle 24 is moved to the left by telescoping. The cylinder 33 drives the slide 32 to move to the left, thereby driving the presser foot 35 and the plate to follow the movement. When the right side of the plate moves onto the pad 15 and the end hits the left end of the positioning baffle 24, it indicates that the bending position of the plate is determined. Then the first hydraulic cylinder 14 controls the movable frame 2 to descend. When the movable frame 2 descends, the transmission action of the first rack plate 19, the first gear 21, the second gear 22 and the second rack plate 25 will drive the positioning baffle 24 to move right until the clamping block 6 is pressed on the surface of the plate. At this time, the positioning baffle 24 is completely away from the plate. Then the second hydraulic cylinder 17 is started, and the bending plate 18 is driven to rise by the second hydraulic cylinder 17 to realize the bending of the plate.

[0039] Furthermore, a vertical linear motion module 29 is fixedly installed on the left side of the interior of the workbench 1, and the vertical linear motion module 29 can control the lifting and lowering movement of the movable seat 30. The movable seat 30 is installed on the driving end of the vertical linear motion module 29, and the movable seat 30 provides an installation position for the components above and on the right side. A cross frame 31 is fixedly installed on the upper side of the right end of the movable seat 30, and the cross frame 31 provides an installation support for the internal slide 32. The slide 32 is movably installed inside the cross frame 31, and the slide 32 can move within the cross frame 31. A telescopic cylinder 33 is fixedly installed on the left side of the interior of the cross frame 31, and the driving end of the telescopic cylinder 33 is fixedly connected to one side of the slide 32, and the telescopic cylinder 33 can control the left and right movement of the slide 32. A second motor 34 is fixedly installed on the top of the slide 32, and the second motor 34 provides power for the rotation of the presser foot 35. The driving end of the second motor 34 passes through the interior of the slide 32 and is fixedly installed with the presser foot 35 through the movable shaft, and the presser foot 35 can press the plate and drive the plate to move.

[0040] Furthermore, a mounting plate 36 is fixedly connected to the lower side of the right end of the movable seat 30, and the mounting plate 36 provides a mounting position for the components below. A slide 37 is movably installed on the front and rear sides of the top end of the mounting plate 36 through a guide rail. The slide 37 can slide on the mounting plate 36, and two straight slots 28 are opened on both sides of the interior of the placement table 26. The straight slots 28 provide channels for the movement of the splint 41. The top sides of the slide 37 are fixedly connected with splints 41, and the ends of the splints 41 pass through the interior of the corresponding side straight slots 28 and extend above them. The splints 41 can perform straightening operations on the plates.

[0041] Furthermore, a third motor 38 is fixedly installed in the middle of the bottom end of the mounting plate 36. The third motor 38 provides power for the rotation of the turntable 39. The driving end of the third motor 38 passes through the interior of the mounting plate 36 and is fixedly installed with the turntable 39. The turntable 39 can drive the connecting rod 40 to move. Connecting rods 40 are movably installed on both sides of the top of the turntable 39. The connecting rod 40 can transmit the movement of the turntable 39 to the slide 37. The ends of the connecting rods 40 are movably installed in the middle of the inner end of the corresponding side slide 37.

[0042] Specifically, the plate to be bent is placed on the placing table 26, and then the vertical straight selection motion module 29 is used to control the movable seat 30 to rise. When the movable seat 30 rises, it will drive the cross frame 31 and the mounting plate 36 to rise together. When the mounting plate 36 rises, it will drive the clamping plates 41 on both sides of the slide 37 to rise, so that the top of the clamping plate 41 passes through the straight slot 28, and then the third motor 38 is started. The turntable 39 is driven to rotate by the third motor 38. The rotating turntable 39 will drive the inner ends of the two connecting rods 40 to move inward, thereby pulling the two slides 37 to move inward at the same time, and then driving the four clamping plates 41 to move inward at the same time. The sheet placed on the placement table 26 is straightened to improve the quality of later bending. Then the vertical linear motion module 29 controls the movable seat 30 to descend, driving the cross frame 31 and the mounting plate 36 to descend together. When the mounting plate 36 descends, it will drive the clamping plate 41 to descend to below the straight slot 28 to prevent the position change of the sheet in the later stage from being affected. When the cross frame 31 descends, it will drive the presser foot 35 to descend, so that the presser foot 35 contacts and presses the upper surface of the sheet. At the same time, since a plurality of balls 27 are movably provided on the surface of the placement table 26, when the presser foot 35 moves, it will drive the sheet to move together and will not cause wear to the bottom surface of the sheet.
