Description

Technical Field

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

[0002] The distribution cabinet is a key device for receiving and distributing electric energy in the power system. The distribution cabinet is mainly composed of a shell, switches, wires and protective devices. The shell of the distribution cabinet is one of the important components of the distribution cabinet. Its main function is to protect the internal electrical equipment and components from the influence of the external environment. The shell of the distribution cabinet is usually made of metal sheets through cutting, bending and assembly.

[0003] At present, when the cut plate is transported to the corresponding position of the bending machine, the plate is usually transported to the conveying device by a robot arm, and then the end of the plate is transported to the bending machine by the conveying device, so that the bending machine bends the plate. At the same time, the conveying device drives the plate to rotate 90 degrees each time to realize the bending process of the plate. Then, the plate after the bending process is transported to the subsequent workstation by the robot arm.

[0004] However, the following problems exist when the plate is conveyed to the corresponding position of the bending machine: 1. When the plate is conveyed to the bending machine, the position of the plate to be bent may be tilted, which will affect the subsequent assembly of the distribution cabinet, and the plate usually needs to be bent multiple times, and the existing conveying device cannot accurately feed the plate, resulting in deviations in the bending position of the plate, further affecting the subsequent assembly of the distribution cabinet, and thus reducing the overall strength of the distribution cabinet; 2. Since the plate of the distribution cabinet is usually thin and has a certain degree of flexibility, it is easy to cause unevenness such as bending on the surface of the plate to be bent, which may cause stress concentration during bending and cause cracks on the surface of the plate, affecting the quality of the plate after bending; 3. When conveying the bent plate, the bending part of the plate cannot be protected, which may cause rebound at the bending part of the plate, and the plate that rebounds needs to be manually processed for secondary processing, affecting the processing efficiency of the distribution cabinet.

When the four clamping rods 382 are clamped at the four corners of the plate, the plate to be bent on the front and rear sides are arranged horizontally. At the same time, the connecting rod 381 drives the positioning plate 384 to move synchronously, so that the positioning plate 384 can fit the ends of the front and rear ends of the plate under the action of the connecting spring 383, and by reading the reading of the scale groove corresponding to the positioning plate 384 on the rear side, the distance between the end of the plate and the rear end of the base 1 can be accurately measured. Since the distance between the base 1 and the bending machine is fixed, when the end of the plate is bent multiple times, the electric telescopic rod 234 can be accurately controlled according to the bending position of the end of the plate to accurately load the plate.

[0052] When the position of the connecting rod 381 is adjusted, the connecting rod 381 can drive the adjustment plate 41 to move synchronously, and then when the clamping rod 382 is clamped at the edge corner of the plate, the connecting rod 381 finally drives the smoothing plate 45 to move to the corresponding position of the plate to be bent through the adjustment plate 41, and the smoothing plate 45 is pressed on the plate to be bent under the action of the downward spring rod 44, and then according to the distance between the two connecting rods 381 arranged on the left and right, the second synchronization mechanism 42 is controlled to drive the two smoothing plates 45 to move away from each other through the synchronization plate 43, so that the smoothing plate 45 flattens the plate to be bent, and the synchronization plate 43 can drive the flattening mechanism 46 to flatten the plate to be bent, further ensuring the effect of flattening the plate to be bent.

[0053] See also Figure 8 , Fig.10 and Fig.11 The two synchronous plates 43 are provided with square holes on the opposite sides thereof, and the flattening mechanism 46 comprises a connecting block 461 slidably mounted in the square hole, a return spring 462 is connected between the connecting block 461 and the inner wall of the square hole, an impact spring rod 463 is slidably mounted on the lower end of the connecting block 461, and the upper end of the impact spring rod 463 slides up and down through the connecting block 461, and a matching rod 464 is fixedly mounted on the side of the impact spring rod 463 away from the middle of the adjusting plate 41 and located above the connecting block 461, and a flattening plate 46 is fixedly mounted on the lower end of the impact spring rod 463 5; wherein, the elastic force of the return spring 462 is much greater than the elastic force of the impact spring rod 463; two groups of lifting blocks 411 arranged in mirror images on the left and right are fixedly installed on the opposite sides of the two adjustment plates 41, and each group includes a plurality of lifting blocks 411 evenly arranged on the left and right, and one side of the upper end of a plurality of lifting blocks 411 close to the middle of the adjustment plate 41 is set as an inclined surface, and a lifting rod 466 is fixedly installed on the side of the impact spring rod 463 close to the adjustment plate 41 and located above the connecting block 461, and the inclined surface of the lifting block 411 is used to drive the lifting rod 466 to move upward.

[0054] The flattening mechanism 46 is used to flatten the surface of the plate; specifically, when the two synchronous plates 43 move synchronously in the directions away from each other, the synchronous plate 43 drives the two impact spring rods 463 to move synchronously in the directions away from each other through the reset spring 462 and the connecting block 461, and then the impact spring rod 463 drives the two flattening plates 465 to move synchronously in the directions away from each other, and when the impact spring rod 463 drives the lifting rod 466 to move to the corresponding position of the inclined surface of the lifting block 411 and continues to move, the inclined surface of the lifting block 411 and the lifting rod 466 cooperate to drive the flattening plate 465 to move upward through the impact spring rod 463, and when the lifting rod 466 and the lifting block 411 are separated, the flattening plate 465 flattens the part of the plate to be bent under the action of the rebound force of the impact spring rod 463, and the lifting block 411 is provided with multiple ones, so that the flattening plate 465 continuously flattens the surface of the plate to achieve the flattening of the surface of the plate.

[0055] See also Figure 8 , Fig.10 and Fig.11 A square groove is provided at the rear end of the matching rod 464. The upper ends of the two synchronous plates 43 arranged front and rear are opposite to each other and the positions corresponding to the square groove of the matching rod 464 are both slidably installed with an L-shaped locking rod 468 through a top extension spring 467. The locking rod 468 is arranged vertically and its horizontal section is located above the matching rod 464. The locking rod 468 is used to cooperate with its corresponding square groove to lock the vertical position of the matching rod 464. The lower ends of the opposite sides of the horizontal sections of the two locking rods 468 arranged front and rear are both set as inclined surfaces; two L-shaped symmetrically arranged left and right sides are fixedly installed on the opposite sides of the two adjustment plates 41. The unlocking rod 412 of the structure, the installation position of the unlocking rod 412 corresponds to the initial position of the matching rod 464, and the unlocking rod 412 is arranged horizontally, and the opposite sides of the two lateral sections of the unlocking rod 412 close to one end of the adjustment plate 41 are arranged to be inclined surfaces for moving the locking rod 468 out of the square groove; the position of the matching rod 464 corresponding to the upper end of the connecting rod 381 is fixedly installed with a baffle plate 385, and the side of the baffle plate 385 close to the matching rod 464 is fixedly installed with a trapezoidal plate 386, and the inclined surfaces of the trapezoidal plates 386 arranged on the left and right are arranged opposite to each other, and the inclined surfaces of the trapezoidal plates 386 are used to drive the matching rod 464 to move upward.

[0056] When the two synchronous plates 43 move synchronously in the direction away from each other to the extreme position, at this time, the matching rod 464 can first cooperate with the inclined surface of the trapezoidal plate 386 to drive the impact spring rod 463 to move upward, so that the pressure plate 465 moves above the smoothing plate 45, and at the same time, the lifting rod 466 can move above the lifting block 411, and the matching rod 464 can cooperate with the inclined surface of the locking rod 468 to drive the locking rod 468 to move in the direction away from the matching rod 464. When the matching rod 464 moves to the upper limit position, at this time, the horizontal section of the locking rod 468 can be inserted into the square groove on the rear side of the matching rod 464 to lock the vertical position of the matching rod 464, and the baffle 385 can block the matching rod 464, so that the two impact spring rods 463 cannot continue to move in the direction away from each other and compress the reset spring 462 through the connecting block 461, so that the two synchronous plates 43 can drive the two smoothing plates 45 to move in the direction away from each other to the left and right extreme positions of the plate bending point, thereby realizing comprehensive leveling of the plate bending point.

[0057] When the two synchronous plates 43 begin to return to their initial positions in the direction of approaching each other, the matching rod 464 is in a locked state under the action of the locking rod 468, so that the lifting rod 466 no longer cooperates with the lifting block 411, and the connecting block 461 returns to its initial position under the action of the reset spring 462. When the synchronous plate 43 returns to its initial position, the vertical section of the locking rod 468 is pulled out of the square groove under the action of the inclined surface of the unlocking rod 412, thereby releasing the lock on the matching rod 464, and allowing the pressing plate 465 to return to its initial position under the action of the rebound force of the impact spring rod 463.

[0058] See also Figure 1 and Figure 4 The protection mechanism 34 includes two side guard plates 341 symmetrically arranged on the left and right sides below the top plate 31, and two protection plates 342 symmetrically arranged on the front and back sides below the top plate 31. Both left and right ends of the protection plates 342 are set as elastic telescopic structures. The back sides of the two protection plates 342 and the back sides of the two side guard plates 341 are slidably installed with pressure plates 348 through pressure spring rods 343. The middle parts of the back sides of the multiple pressure plates 348 are fixedly installed with electric multi-stage telescopic rods 344. The ends of the electric multi-stage telescopic rod 344 away from the pressure plate 348 are connected to the top plate 31 through the connecting rod 345; the left and right ends of the protective plate 342 are located between the two side guard plates 341; the lower end of the connecting rod 345 is arranged as a telescopic structure, and the telescopic end of the connecting rod 345 and the opposite side of the connecting plate 33 are hingedly connected with a changing rod 346, and both ends of the changing rod 346 are arranged as telescopic structures, and the middle part of the upper end of the changing rod 346 is hinged with the vertical rod 347 fixedly installed at the lower end of the top plate 31.

[0059] The protective mechanism 34 is used to protect the bending part of the plate; specifically, when the bending of the plate is completed, the No. 1 electric push rod 32 is controlled to drive the connecting plate 33 to move upward, and the direction-changing rod 346, under the action of the vertical rod 347, causes the connecting plate 33 to drive the telescopic end of the connecting rod 345 to move downward through the direction-changing rod 346, so that the telescopic end of the connecting rod 345 finally drives the lower ends of the protective plate 342 and the side guard plates 341 to fit on the upper side of the conveying plate 21 through the electric multi-stage telescopic rod 344, and then controls the electric multi-stage telescopic rod 344 to drive the pressure plate 348 to move in the direction close to the plate, so that the pressure plate 348 drives its corresponding protective plate 342 and side guard plates 341 to fit on the front and rear ends and left and right ends of the plate respectively through the pressure spring rod 343, and the protective plate 342 and the side guard plates 341 continue to press against the bending part of the corresponding plate under the action of the pressure spring rod 343, thereby preventing the plate from rebounding at the bending part, thereby increasing the processing efficiency of the distribution cabinet.
