Description

Technical Field

[0001] The invention relates to the technical field of plate bending, and in particular to a plate bending device for a power distribution cabinet. Background Art

[0002] The panels of the power distribution cabinet need to be bent during processing. Through bending, the power distribution cabinet can be more solid and withstand greater pressure and impact, thereby better protecting the internal electrical components. In addition, bending can also optimize the structure of the power distribution cabinet and reduce the gaps in the corners. At the same time, bending can make the power distribution cabinet better adapt to the installation environment, improve space utilization, and facilitate the layout and wiring of electrical components.

[0003] The patent document with announcement number CN218224146U discloses a plate bending machine for power distribution cabinet production, including a bending machine, a bending die, an operating table fixedly installed on the bending machine, the operating table is in contact with the bending die, a driving structure fixedly installed on one side of the operating table, a feeding structure movably installed on the top side of the operating table, a flip stripping structure movably installed on the feeding structure, the flip stripping structure movably installed on one side of the operating table, and a driving structure including a driving motor, which is fixedly installed on one side of the operating table. Through the setting of the operating table, push rod and other structures, the plate of the power distribution cabinet is placed on the operating table when in use, and the driving motor is started to make the push rod push the plate to the bending die for processing.

[0004] However, the solution still has the following problems: after the plate is placed on the operating table, the driving motor drives the push rod to contact the plate and drive the plate to move. However, when the push rod cooperates with the plate and drives the plate to move toward the bending mold, the plate is prone to deviation, which causes errors in the bending of the plate and affects the bending quality.

[0005] In addition, in other existing technologies, a top plate parallel to the bending mold is provided on the inner side of the bending mold, and the top plate is manually aligned and abutted to reduce the offset error of the plate. However, offset may still occur due to looseness, and when the plate is large, multiple workers are required to work together, which is cumbersome and will also affect the bending efficiency of the plate. Summary of the invention

[0006] The present invention provides a plate bending device for a power distribution cabinet, aiming to solve the problem in the related art that the plate is easily offset when being placed in a bending mold.

[0007] The plate bending device of the power distribution cabinet of the present invention comprises a bending assembly arranged on a frame, and further comprises: a conveying member, an adjusting assembly, a switch assembly, and a pressing assembly; the conveying member and the pressing assembly are arranged up and down for conveying the plate, and the adjusting assembly comprises a first adjusting assembly and a second adjusting assembly which are arranged in a front-to-back interval and have the same structure; The first adjustment component includes: a baffle connected to the conveying member, a clamping plate sliding left and right on the baffle, a mounting frame connected to the baffle, a middle frame sliding toward the baffle in the mounting frame, a correction rod mounted on the middle frame, a straw arranged in the middle frame, and a suction nozzle rotatably fitted at the bottom of the straw; a switch component is connected to the straw for controlling the suction nozzle; When the sheet is conveyed at an angle, its side passes through the suction nozzle in the first adjusting component and the suction nozzle in the second adjusting component successively. After the sheet passes through the suction nozzle, the switch component controls the suction nozzle to adsorb the sheet and move with the sheet. The suction tube and the middle frame move with the sheet to drive the correction rod and the card plate to abut against each other. When the card plate moves, the third elastic member undergoes elastic deformation and causes the card plate to gradually stop moving. After the card plates corresponding to the two suction nozzles stop moving, the correction of the sheet is completed. The corrected sheet continues to move to the pressing component, and the suction nozzle releases the sheet at the same time. The pressing component and the conveying member clamp the sheet for conveyance.

[0008] The effect is that the present invention configures an adjustment component and a switch component on the conveying member. When the conveying member conveys the plate, the adjustment component is used to correct and adjust the position of the plate before the plate moves to the pressing component. Specifically, two suction nozzles are adsorbed on the plate, and under the action of the correction rod and the clamping plate, the two suction nozzles stop moving successively until they move to the same front and rear direction, thereby completing the correction of the plate and eliminating the deviation when placing the plate or conveying the plate. Then the adjusted plate enters the pressing component, and the pressing component and the conveying member clamp the plate and convey the plate to the bending component for bending processing, thereby reducing the deviation of the crease of the plate and improving the bending efficiency of the plate.

[0009] Preferably, the switch assembly includes a first switch plate, a push rod and an intermediate rod. A through hole 1 is penetrated through the first switch plate. The first switch plate is slidably arranged on the straw. The intermediate rod is arranged on the side of the straw. The push rod and the intermediate rod are rotatably connected. The push rod is arranged as a telescopic rod. The telescopic end of the push rod is rotatably connected to the first switch plate. When the plate moves, its side edge abuts against the push rod to drive the push rod to rotate, while the first switch plate slides. The sliding of the first switch plate drives the through hole 1 to move to correspond to the channel inside the straw and open the suction nozzle.

[0010] The effect is that the plate moves past the push rod and drives the push rod to rotate, the rotation of the push rod drives the first switch plate to move, the first switch plate drives the through hole to move to the channel of the straw, the straw is opened, and a vacuum pump is used to evacuate air so that the inside of the straw is in a negative pressure state, and the plate is adsorbed by the suction nozzle.

[0011] Preferably, a second switch plate is slidably provided on the straw, and through hole two and through hole three are provided on the second switch plate. When the suction nozzle is opened, through hole two corresponds to the inside of the straw. After the plate moves to the pressing assembly, the second switch plate abuts against the baffle plate to drive the second switch plate to move, and through hole three moves to correspond to the internal channel of the straw and closes the suction nozzle. Through hole three is used to connect the channel of the straw with the outside world.

[0012] The effect is that after the plate moves to the pressing assembly, the second switch plate abuts against the baffle and moves, driving the second through hole to separate from the channel inside the straw and close the straw. At the same time, the third through hole connects the straw to the outside world, eliminating the negative pressure inside the straw so that the suction nozzle can be separated from the plate.

[0013] Preferably, the pressing assembly includes: a rotating rod rotatably assembled on the conveying member, a rotating plate arranged on the side of the rotating rod, and a pressure roller rotatably matched on the rotating plate; the rotating rod and the pressure roller are both arranged parallel to the baffle, and a torsion spring is arranged at the rotating shaft of the rotating rod, and the torsion spring is used to drive the pressure roller downward. After the plate moves to the pressure roller, the torsion spring drives the pressure roller to abut against the side of the plate.

[0014] The effect is that the plate moves to the rotating plate and continues to move, driving the rotating plate to rotate until the pressure roller abuts against the side of the plate. The pressure roller cooperates with the conveying member to clamp the plate, reducing the deviation of the plate during the conveying process.

[0015] Preferably, an insertion rod is provided at one end of the card plate away from the bending portion, and a slot cooperating with the insertion rod is provided on the side of the rotating rod. The movement of the card plate drives the insertion rod away from the slot, and the pressure roller abuts against the plate after the card plate stops moving.

[0016] The effect is that after the clamping plate stops moving, the plate is corrected, and at the same time the insertion rod is separated from the slot, releasing the restriction on the rotating rod, so that the plate drives the rotating plate to rotate, so that the pressure roller abuts against the plate.

[0017] Preferably, a plurality of rubber rings are arranged at intervals on the side surface of the pressure roller along its length direction, and the pressure roller abuts against the plate through the rubber rings.

[0018] The effect is that the rubber ring is provided to reduce the deviation of the plate during the conveying process.

[0019] Preferably, a slider is provided in the middle frame for sliding left and right, the slider is sleeved on the outside of the straw, and the straw is connected to the middle frame through the slider.

[0020] The effect is that the suction nozzle can move forward and backward relative to the conveying direction of the plate when correcting the plate, so that the two relatively inclined suction nozzles move to be parallel to the baffle to correct the plate.

[0021] Preferably, a second elastic member is disposed outside the straw, and the second elastic member is connected to the second switch plate to drive the second through hole to correspond to the channel inside the straw.

[0022] The effect is that after the processing of the plate is completed, the second elastic member drives the second switch plate to move to the initial position, so as to control the suction nozzle to separate from the plate again and adjust the position of the plate.

[0023] Preferably, a first elastic member for connecting the installation frame and the middle frame is provided between the installation frame and the middle frame, and the first elastic member is used to drive the middle frame to move and reset in a direction away from the baffle.

[0024] The effect is that the first elastic member drives the middle frame to move to the initial position and reset, so as to adjust and correct the position of the plate again.

[0025] Beneficial effects: The present invention absorbs the plate through two suction nozzles and moves with the plate when the plate is conveyed, and at the same time, under the action of the correction rod and the clamping plate, the two suction nozzles are moved to be parallel to the baffle to complete the correction of the plate, and then the plate is clamped and conveyed by the pressure roller and the conveying member, thereby reducing the deviation of the plate during processing. During the entire processing process, the plate only needs to be placed on the conveying member, and the deviated plate can be corrected without affecting the bending of the plate, and no manual assistance is required to support the plate, thereby reducing the deviation of the plate during bending, and improving the bending effect and efficiency of the plate.

DETAILED DESCRIPTION

[0037] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0038] like Figure 1 and Figure 2 As shown, the plate bending device for the power distribution cabinet of the present invention comprises: a bending assembly 11 arranged on a frame 1 for bending a plate 01, a conveying assembly for conveying the plate 01 to the bending assembly 11, and a rotating assembly 2 for driving the plate 01 to rotate during bending. The rotating assembly 2 is connected to the conveying assembly, and the conveying assembly conveys the plate 01 to the bending assembly 11 for bending. While bending, the rotating assembly 2 drives the plate 01 to rotate through the conveying assembly, and cooperates with the bending assembly 11 to bend the plate 01.

[0039] Reference Figures 3 to 7The conveying component includes: a conveying member 3, an adjusting component, a switch component 6, a pressing component 7, and a control component 8. The adjusting component, the switch component 6, the pressing component 7, and the control component 8 are all assembled on the conveying member 3 and arranged above the conveying member 3 at intervals. The conveying member 3 is configured as a belt conveyor. The plate 01 is conveyed above the conveying member 3. The adjusting component is used to correct and adjust the plate 01. The pressing component 7 limits the plate 01 when the plate 01 enters the bending component 11. The switch component 6 is used to control the coordination between the adjusting component and the plate 01, and the control component 8 is used to control the coordination between the pressing component 7 and the plate 01.

[0040] The conveyor 3 is used to drive the sheet 01 to move left and right. It moves to the right to convey the sheet 01 to the bending assembly 11 for bending. After the bending is completed, it drives the sheet 01 to move to the left to take the sheet 01 out. When the conveyor 3 drives the sheet 01 to move to the right, it will pass through the adjustment assembly and the pressing assembly 7 in sequence. Specifically, when the sheet 01 moves through the switch assembly 6, the adjustment assembly cooperates with the sheet 01 to correct the position of the sheet 01 so that the side of the sheet 01 is facing the bending assembly 11, that is, the fold of the sheet 01 is parallel to the side of the sheet 01. After the correction of the sheet 01 is completed, the control assembly 8 controls the pressing assembly 7 to cooperate with the sheet 01. After the pressing assembly 7 cooperates with the sheet 01, the adjustment assembly separates from the sheet 01, and the pressing assembly 7 cooperates with the conveyor 3 to convey the sheet 01 to the bending assembly 11.

[0041] Reference Figure 3 The adjustment component includes a first adjustment component 4 and a second adjustment component 5. The first adjustment component 4 and the second adjustment component 5 have the same structure, and the first adjustment component 4 and the second adjustment component 5 are arranged with a front-to-back interval.

[0042] Reference Figures 3 to 6The first adjustment component 4 includes: a baffle 41, a card plate 42, a mounting frame 43, an intermediate frame 44, a correction rod 45, a suction pipe 46, a suction nozzle 47, a first elastic member 48, a third elastic member 49, and a slider 461. A mounting plate 31 for mounting the baffle 41 is provided on the conveying member 3. The baffle 41 is arranged above the conveying member 3 and perpendicular to the conveying direction of the plate 01. The card plate 42 penetrates the baffle 41 and slides left and right on the baffle 41. The mounting frame 43 is connected to the side of the baffle 41 away from the bending component 11. The intermediate frame 44 slides left and right on the mounting frame 43, that is, slides toward the baffle 41. The correction rod 45 is arranged on a side of the intermediate frame 44 close to the baffle 41, and the correction rod 45 is arranged toward the baffle 41. One end of the card plate 42 close to the correction rod 45 is provided A bending portion 421 is provided, and the first elastic member 48 and the third elastic member 49 are both configured as springs. The third elastic member 49 is respectively connected to the card plate 42 and the baffle 41. The third elastic member 49 is used to drive the card plate 42 to move toward the direction of the correction rod 45. The first elastic member 48 is arranged in the installation frame 43 and connected to the middle frame 44. The first elastic member 48 is used to drive the middle frame 44 to slide and reset in the direction away from the baffle 41. The slider 461 is sleeved on the outside of the straw 46. The slider 461 slides back and forth in the middle frame 44, that is, the sliding direction of the slider 461 in the middle frame 44 is parallel to the baffle 41. The suction nozzle 47 is rotatably arranged at the bottom of the straw 46. The top of the straw 46 is connected to the vacuum pump. The switch assembly 6 is connected to the straw 46 to control the closure of the inside of the straw 46.

[0043] The baffle plate 41 in the second adjustment component 5 and the baffle plate 41 in the first adjustment component 4 are arranged in the same plane, and the first adjustment component 4 and the second adjustment component 5 are both arranged on the same side of the baffle plate 41 .

[0044] When the sheet 01 is conveyed, the correction process is as follows: in the initial state, the suction nozzle 47 of the first adjustment component 4 and the suction nozzle 47 in the second adjustment component 5 are parallel to the fold of the sheet 01. When the sheet 01 is conveyed, it moves to the switch component 6. If the side of the sheet 01 is tilted, it will cooperate with the switch component 6 in the first adjustment component 4 or the second adjustment component 5 in turn, and then cooperate with the switch component 6 in the second adjustment component 5 or the first adjustment component 4. The vacuum pump evacuates the inside of the suction pipe 46, so that the inside of the suction pipe 46 is in a negative pressure state, so that the suction nozzle 47 in the first adjustment component 4 or the second adjustment component 5 sucks the suction nozzle 47 in turn. Attached to the plate 01, after the two suction nozzles 47 are adsorbed on the plate 01, the plate 01 continues to be conveyed to drive the two middle frames 44 to move, and the movement of the two middle frames 44 drives the corresponding correction rods 45 to successively abut against the card plate 42, and the correction rods 45 drive the card plate 42 to slide relative to the baffle 41. The movement of the card plate 42 drives the third elastic member 49 to deform. As the deformation of the third elastic member 49 gradually increases, the card plate 42 will gradually stop moving. After the two card plates 42 stop moving, the moving strokes of the two are the same, and the two suction nozzles 47 drive the side of the plate 01 to be parallel to the fold of the plate 01, thereby completing the correction of the plate 01.

[0045] The specific correction process is as follows: the correction rod 45 in the first adjustment component 4 first contacts the baffle 41, the middle frame 44 in the second adjustment component 5 continues to move, and the suction nozzle 47 rotates at the end of the suction tube 46, and the slider 461 slides back and forth in the middle frame 44 until the movement strokes of the two clamping plates 42 are the same. The slider 461 slides in the middle frame 44 to adjust the two inclined suction nozzles 47 to be parallel to the baffle 41. When the middle frame 44 moves to the right, the first elastic member 48 undergoes elastic deformation. After the suction nozzle 47 is separated from the plate 01, the first elastic member 48 drives the middle frame 44 to move to the initial position, so as to correct the position of the plate 01 again.

[0046] Here, after the two clamping plates 42 have moved the same stroke, they move together for a certain stroke and then gradually stop moving, so as to ensure that the clamping plates 42 have completed the correction of the plate 01 when they stop moving.

[0047] Reference Figures 5 to 7The switch assembly 6 includes a first switch plate 61, a second switch plate 62, a push rod 63, an intermediate rod 64, and a second elastic member 65. The first switch plate 61 is provided with a through hole 1 611, and the second switch plate 62 is provided with a through hole 2 621. The first switch plate 61 and the second switch plate 62 are both slidable on the straw 46 in a direction perpendicular to the center line of the straw 46. The intermediate rod 64 is arranged on the side of the straw 46. The middle position of the push rod 63 is rotatably matched with the intermediate rod 64. The push rod 63 is arranged to be telescopic. The telescopic end of the push rod 63 is rotatably connected to the first switch plate 61, the second elastic member 65 is set as a spring, the second elastic member 65 is set outside the straw 46 and connected to the second switch plate 62, the second elastic member 65 is used to drive the second through hole 621 to correspond to the channel inside the straw 46, and drive the second switch plate 62 to move toward the baffle 41, the second switch plate 62 is provided with a third through hole 622, one end of the third through hole 622 is set inside the straw 46, and the other end is set outside the straw 46. The second switch plate 62 corresponds to the baffle 41, and when the second switch plate 62 moves to abut against the baffle 41, it moves relative to the straw 46, driving the second through hole 621 to be misaligned with the channel inside the straw 46, and at the same time, the third through hole 622 corresponds to the channel inside the straw 46.

[0048] Specifically, the suction nozzle 47 is divided into three states. When both the through hole 1 611 and the through hole 2 621 correspond to the channel inside the suction tube 46, the suction nozzle 47 is in an open state; when the through hole 1 611 or the through hole 2 621 is misaligned with the channel inside the suction tube 46, the first switch plate 61 or the second switch plate 62 blocks the inside of the suction tube 46, and the suction nozzle 47 is in a closed state; when the through hole 2 621 is misaligned with the channel inside the suction tube 46, the through hole 3 622 corresponds to the inside of the suction tube 46. At this time, the inside of the suction nozzle 47 is connected to the outside through the channel 3, the negative pressure inside the suction nozzle 47 is eliminated, the suction nozzle 47 is separated from the plate 01, and the suction nozzle 47 is in a separated state.

[0049] Reference Figures 6 to 9 In the initial state, the through hole 1 611 is staggered with the channel inside the suction tube 46, the push rod 63 is in a vertical state, and the suction nozzle 47 is in a closed state; when the plate 01 moves to the suction nozzle 47, the plate 01 moves to abut against the push rod 63, and the plate 01 continues to move to drive the push rod 63 to rotate, and the rotation of the push rod 63 drives the first switch plate 61 to move until the push rod 63 rotates to cooperate with the side of the plate 01, and the through hole 1 611 moves to correspond to the internal channel of the suction tube 46, and the suction tube 46 is opened. At this time, the suction nozzle 47 is in an open state, and the suction nozzle 47 adsorbs the plate 01 to adjust the position of the plate 01; the plate 01 continues to move, and after the pressing assembly 7 presses the plate 01, the second switch plate 62 moves to abut against the baffle 41, driving the second switch plate 62 to move relative to the suction tube 46 until the through hole 3 622 corresponds to the inside of the suction tube 46, at which time the suction nozzle 47 is in a separated state, and the suction nozzle 47 is separated from the plate 01.

[0050] Reference Figure 6 In addition, the push rod 63 is set as a telescopic rod, so that when the push rod 63 rotates, it can drive the first switch plate 61 to slide left and right to control the switch of the suction nozzle 47.

[0051] Reference Figure 5 and Figure 7 The pressing assembly 7 includes a rotating rod 71, a rotating plate 72 and a pressure roller 73. The rotating rod 71 and the pressure roller 73 are arranged parallel to the baffle 41, and the rotating rod 71 is rotatably arranged on the mounting plate 31, that is, the rotating rod 71 is rotatably arranged on the conveying member 3, the rotating plate 72 is arranged on the side of the rotating rod 71, and the pressure roller 73 is rotatably arranged at the bottom of the rotating plate 72. A torsion spring is arranged at the rotating shaft of the rotating rod 71. In the initial state, the rotating plate 72 is vertically downward, and the plate 01 drives the rotating plate 72 to rotate when passing the pressure roller 73, until the pressure roller 73 cooperates with the side of the plate 01, and at the same time, the torsion spring is deformed by force, driving the pressure roller 73 to maintain abutment with the plate 01, restricting the corrected plate 01, and reducing the deviation of the plate 01 during transportation.

[0052] Reference Figure 7 A plurality of rubber rings 731 are provided on the side of the pressure roller 73 along its length direction. The pressure roller 73 abuts against the plate 01 through the rubber rings 731. The friction between the pressure roller 73 and the plate 01 is increased through the rubber rings 731, thereby reducing the deviation of the plate 01 during transportation and further improving the stability of the plate 01.

[0053] Reference Figure 5 and Figure 7 The control component 8 includes an insertion rod 81, which is arranged at one end of the card plate 42 away from its bending portion 421. The end of the insertion rod 81 close to the bending portion 421 is arranged to be pointed. The tip of the insertion rod 81 is arranged toward the rotating rod 71, and a slot 711 is opened on the side of the rotating rod 71.

[0054] In the initial state, the insertion rod 81 is inserted into the slot 711 to restrict the rotating rod 71. When the correction rod 45 completes the correction of the plate 01, the insertion rod 81 is separated from the slot 711, and a gap exists between the bending portion 421 and the baffle 41. The correction rod 45 drives the clamping plate 42 to continue to move, and drives the plate 01 to move to the pressure roller 73 to restrict the plate 01.

[0055] Reference Fig.10The rotating assembly 2 includes a driving member 21 and an arc rod 22. The arc rod 22 is arranged in an arc shape around the fold of the plate 01. The arc rod 22 is slidably arranged on the frame 1 along its length direction. The driving member 21 is arranged as a motor. A gear 211 is arranged at the output end of the driving member 21. A tooth groove 221 meshing with the gear 211 is arranged on the side of the arc rod 22. The arc rod 22 is connected to the conveying member 3. The driving member 21 drives the arc rod 22 to rotate through the gear 211. The arc rod 22 drives the conveying member 3 and the plate 01 to rotate, so that the plate 01 rotates around its fold when bending, so as to bend the plate 01 to a specified angle.

[0056] The implementation principle of the present invention is as follows: when the sheet 01 is conveyed and tilted, its side passes through two push rods 63 in succession and drives the corresponding push rods 63 to rotate, the push rods 63 rotate and drive the first switch plate 61 to move and open the suction nozzle 47, the suction nozzle 47 adsorbs the sheet 01, and the sheet 01 moves through the suction nozzle 47 to drive the correction rod 45 to move; The correction rod 45 moves to abut against the bent portion 421 of the clamping plate 42, and at the same time the third elastic member 49 is deformed, and the clamping plate 42 gradually stops moving. After both clamping plates 42 stop moving, the moving strokes of the two clamping plates 42 are the same, and the correction of the plate 01 is completed; When the plate 01 is corrected, the insertion rod 81 is separated from the slot 711, and the restriction on the rotating rod 71 is released. The plate 01 continues to move, and the correction rod 45 pushes the push rod 63 to rotate until the pressure roller 73 abuts against the side of the plate 01. The sheet 01 continues to move, driving the second switch plate 62 to abut against the baffle 41. The second switch plate 62 moves relative to the suction tube 46 until the through hole 622 corresponds to the channel inside the suction tube 46. While the second switch plate 62 blocks the exhaust channel, the interior of the suction tube 46 is connected with the outside world, and the negative pressure state inside the suction nozzle 47 is released. The air pressure inside the suction nozzle 47 is the same as that of the outside world, and the suction nozzle 47 is separated from the sheet 01. At this time, the pressure roller 73 cooperates with the conveying member 3 to convey the corrected sheet 01 to the bending assembly 11 for bending operation.
