Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power distribution cabinet production and processing, and particularly relates to a power distribution cabinet body bending forming device and method. BACKGROUND

[0002] In the production process of the power distribution cabinet, the bending forming of the cabinet body is a key link. The traditional power distribution cabinet body bending forming method and equipment have many problems, which seriously affect the production efficiency and product quality. In the prior art, common bending methods such as manual bending completely rely on the experience and operation skills of workers, and have high labor intensity and extremely low production efficiency. Workers are prone to fatigue after long-time repeated operation, which makes it difficult to guarantee the bending precision.

[0003] Some early semi-automatic bending equipment reduces the labor intensity of workers to a certain extent, but still needs frequent manual adjustment of the position of the cabinet body plate and the parameters of the equipment. When the cabinet body plate of different specifications is replaced for bending, workers need to spend a lot of time to re-measure, position and debug the equipment.

[0004] A bending device for power distribution cabinet accessory production is disclosed in Chinese Patent No. CN222842882U, which includes a workbench, a rack fixedly installed on the upper surface of the workbench, a gas cylinder fixedly installed on the upper surface of the rack, a lifting plate fixedly installed on the output end of the gas cylinder and penetrating through the rack, and a bending knife plate fixedly installed on the lower surface of the lifting plate. The worker fixes the cabinet body plate on the surface of the forming die, and then starts the first motor to drive the output shaft to rotate the bidirectional screw rod. The rotating bidirectional screw rod drives the two moving blocks to move relative to each other through the threaded rotation, so that the two clamping plates clamp and position the cabinet body plate. The positioning time is short, the overall production efficiency is improved, the positioning accuracy during positioning is high, and the quality and performance of the power distribution cabinet accessory are improved.

[0005] However, the above-mentioned bending device still has some deficiencies in actual use: 1. First, the cabinet body plate usually has front and back differences. The outer side is usually a smooth surface (bright surface), and the inner side is a rough surface (pre-treated or retaining rolling marks). When bending, the rough surface should be bent towards the rough surface, so that the rough surface is inside the cabinet body to ensure the appearance quality and structural strength. In the traditional process, the front and back of the cabinet body plate need to be identified manually and the placement direction needs to be adjusted, which not only has low efficiency, but also is prone to bending direction errors due to human negligence, causing material waste and rework.

[0006] 2、Further, in the traditional bending process, the cabinet body plate conveying, front and back identification, clamping positioning, bending forming and other links need manual operation, the single process time is long, and it is difficult to meet the large-scale production demand. With the rise of labor cost and the development of intelligent manufacturing, the whole process automation of power distribution cabinet body bending needs to be realized to improve production efficiency and reduce labor cost.

[0007] 3、Secondly, the existing bending equipment lacks versatility, and the type change adjustment is complicated. The specifications of the power distribution cabinet body are various, and different types of cabinet bodies correspond to different sizes and bending requirements. The mold of the traditional bending equipment is fixed in size, and when the production specification is changed, the old mold needs to be disassembled and the new mold needs to be installed, which usually takes several hours, seriously affecting the production continuity.

DETAILED DESCRIPTION

[0041] The following Figures 1-16 The application is further described in detail.

[0042] The embodiment of the application discloses a power distribution cabinet body bending forming device and method, the existing device has low automation degree, and production efficiency is limited, secondly, the existing device depends on manual identification of front and back surfaces, and the bending direction error is prone to occur, further, the existing device has obvious bending rebound phenomenon, and precision control is difficult, therefore, the application provides a power distribution cabinet body bending forming device to solve the above problems.

[0043] Referring to Figure 1 and Figure 2 , a power distribution cabinet body bending forming device comprises a static bending platform 1.

[0044] The device body comprises the static bending platform 1, the platform serves as a basic bearing structure, the top is integrated with an identification part 3 for identifying the front and back surfaces of the cabinet body plate 100, a bending part 2 for realizing bending operation, and a clamping piece 5 for clamping and adjusting the position of the cabinet body plate 100, to ensure that the parts work cooperatively.

[0045] When the cabinet body plate 100 needs to be processed, it is first conveyed by an existing known conveying device, which is not marked in the figure, and two conveying devices are arranged on the two sides of the bending platform 1 in the length direction, one conveying the power distribution cabinet body to be processed, and the other conveying the power distribution cabinet body after processing, to ensure the normal conveying of the cabinet body plate 100.

[0046] When the conveying device conveys the cabinet body plate 100, referring to Figure 1 , along the length direction of the bending platform 1, it will pass through the identification part 3 and the clamping part 5 in turn.

[0047] Therefore, the cabinet body plate 100 needs to identify its front and back sides first, and the front and back sides of the cabinet body plate 100 need to use the identification part 3, as follows: Referring to Figure 2 and Figure 3 , it is the overall structure diagram of different perspectives of the identification part 3; the identification part 3 is installed at the input end of the bending platform 1, used to automatically identify the inner side (rough surface) and the outer side (smooth surface) of the cabinet body plate 100 during the conveying process, to avoid the bending direction error. Its core structure includes auxiliary support 30, detection block 32, magnetic attraction block 33 and identification box 38.

[0048] The identification part 3 includes two groups of three detection blocks 32 symmetrically distributed above and below, and the identification area for the power distribution cabinet body to pass through is arranged between the detection blocks 32, and the magnetic attraction block 33 to be energized is horizontally slidably arranged on the side close to the three detection blocks 32; two groups of fixed shafts 31 are installed on the bending platform 1 through the auxiliary support 30, the auxiliary support 30 is arranged on the bending platform 1, and the detection block 32 is rotatably connected to the fixed shaft 31 through the torsional spring, and the detection block 32 is of telescopic structure.

[0049] The detection block 32 is provided with a movable slot for the magnetic attraction block 33 to slide, and two groups of symmetrical reset springs 35 are installed in the movable slot of the detection block 32, and the two reset springs 35 are arranged on the two sides of the magnetic attraction block 33.

[0050] The specific steps of detecting the front and back sides of the cabinet body plate 100 are as follows: Firstly, the cabinet body plate 100 moves, and the two groups of detection blocks symmetrically distributed above and below move close to each other on the surface of the cabinet body plate 100.

[0051] The position where the detection block 32 contacts the cabinet body plate 100 is provided with the magnetic attraction block 33. After the magnetic attraction block 33 is energized, the magnetic attraction block 33 will generate strong magnetic attraction and attract the metal block 34, so that the magnetic attraction block 33 is corrected in position, so that the magnetic attraction block 33 and the metal block 34 are on the same vertical line, which is equivalent to correcting the position of the magnetic attraction block 33, to ensure that they are on the same starting line.

[0052] After the position of the magnetic attraction block 33 is corrected, the magnetic attraction block 33 is quickly de-energized, and after de-energization, the two magnetic attraction blocks 33 are displaced at different speeds under the friction of the cabinet body plate 100 moving, and after the displacement, the identification metal sheet 37 connected by the tail traction rope 36 is pulled, so as to detect the inner side (rough surface) and the outer side (smooth surface) of the cabinet body plate 100.

[0053] It should be noted that the metal block 34 is embedded in the detection block 32, and its position is not movable, while the magnetic block 33 slides in the movable groove of the detection block 32, and the magnetic block 33 and the metal block 34 are not in the same starting line in the initial state, so that the magnetic block 33 will be quickly powered and de-energized in a short time, and the purpose is to quickly control the magnetic block 33 to approach the metal block 34 after being powered on to generate a magnetic force, so that the two on the upper and lower symmetrical detection blocks 32 are synchronized to restore to the middle position of the detection block groove (i.e. the position of the metal block 34), so that when the front and back surfaces of the cabinet plate 100 are detected, the accuracy of the detection result can be effectively guaranteed.

[0054] When the cabinet plate 100 moves between the detection blocks 32, the difference in surface roughness will cause the contact pressure of the two detection blocks 32 to be different: if the cabinet plate 100 is a bright surface (outer side), it contacts one side of the magnetic block 33, and because the surface is smooth, the friction force on the magnetic block 33 when the cabinet plate 100 moves is relatively small, so the displacement distance of the magnetic block 33 is relatively small, and at this time the other magnetic block 33 contacts the rough surface (inner side), so the surface friction is larger, which will make the cabinet plate 100 move and the magnetic block 33 move with a larger displacement distance, and at this time the recognition box 38 connected thereto senses a large displacement, so it knows that the surface at this time is a rough surface, thereby determining whether the face of the cabinet plate 100 being conveyed is correct.

[0055] If the front and back surfaces of the cabinet plate 100 are incorrect, the subsequent cabinet plate 100 is controlled to perform a turnover operation, and if the face of the cabinet plate 100 is not incorrect, it can be directly bent.

[0056] When the magnetic block 33 detects the front and back surfaces of the cabinet plate 100 by the difference in friction, the recognition box 38 is also involved, and the recognition metal sheet 37 and the sensing sheet 40 inside the recognition box 38 are the core components, specifically: Referring to Figure 3 , Figure 4 and Figure 5 , the same side of the two groups of magnetic blocks 33 is provided with a traction rope 36, and the end of the traction rope 36 away from the magnetic block 33 is provided with a recognition metal sheet 37.

[0057] The side wall of the auxiliary support 30 is also provided with a recognition box 38, and the recognition box 38 is provided with a guide column 39 which is symmetrical and parallel to the length direction of the recognition box 38, and the recognition metal sheet 37 is slidably arranged on the guide column 39. The recognition box 38 is also provided with a sensing sheet 40, and the recognition metal sheet 37 pulled by the traction rope 36 will abut against the sensing sheet 40.

[0058] When detecting the cabinet body plate 100 of different thicknesses, the detection block 32 can adaptively abut against the surface of the cabinet body plate 100 with the one end provided with the magnetic block 33, because the detection block 32 is a telescopic structure and the inside of the detection block 32 is supported by the spring, thereby avoiding that the magnetic block 33 cannot perfectly abut against the surface of the cabinet body plate 100.

[0059] The specific implementation steps of linkage between the identification box 38 and the magnetic block 33 are as follows: When the cabinet body plate 100 passes through the middle of the two groups of symmetrical detection blocks 32, the two magnetic blocks 33 quickly perform the power-on and power-off operation to correct the positions of the two magnetic blocks 33. At this time, when the cabinet body plate 100 passes through the detection block 32, the magnetic block 33 in contact with the rough surface (the inner side) and the magnetic block 33 in contact with the bright surface (the outer side) move different distances. The identification metal sheet 37 is pulled to slide along the guide column 39 by the traction rope 36. The identification metal sheet 37 on one side first touches the induction sheet 40, which indicates that it is the rough surface (the inner side). The identification metal sheet 37 on the other side does not touch the induction sheet 40 or finally touches the induction sheet 40, which indicates that it is the bright surface (the outer side).

[0060] Referring to Figure 6 As shown in the figure, the bending platform 1 is provided with two groups of control sleeve rings 42. The inner side of the control sleeve ring 42 is integrally provided with an electric sliding rail 43. The electric sliding block 41 is slidably arranged on the electric sliding rail 43 of the control sleeve ring 42.

[0061] The side close to each other of the two electric sliding blocks 41 is provided with a clamping piece 5 through an electric telescopic rod 56.

[0062] It should be noted that the control sleeve ring 42 is provided with an electric sliding rail 43. The movement of the two electric sliding blocks 41 is controlled by the electric sliding rail 43. The whole is controlled by the electric drive.

[0063] After the cabinet body plate 100 in the conveying process realizes the identification of the front and back surfaces, it is necessary to judge the cabinet body plate 100. If the front and back surface positions of the cabinet body plate 100 are correct, no action is taken, and the cabinet body plate 100 continues to move to the bending processing area.

[0064] However, if the position of the cabinet body plate 100 is incorrect, the electric sliding block 41 is activated to rotate by one hundred and eighty degrees along the electric sliding rail 43 to turn over the cabinet body plate 100, so as to ensure that the position of the cabinet body plate 100 is adjusted.

[0065] But need to note that, when the front and back of the cabinet body plate 100 position is correct, the whole process does not need to be clamped by the clamping piece 5, directly bending can be. When the front and back of the cabinet body plate 100 position is wrong, the clamping piece 5 needs to be clamped, and its rotation is controlled.

[0066] Referring to Figure 7 And Figure 8 As shown in the specific structure diagram of the clamping piece 5.

[0067] The clamping piece 5 includes a clamping frame 50 installed on the output end of the electric sliding block 41, a telescopic spring rod 51 is installed in the middle of the clamping frame 50, a symmetric and vertical distribution of a first rod 52 is provided on the side wall of the telescopic spring rod 51, a triangular block 53 is installed at one end of the first rod 52 close to the telescopic spring rod 51, the telescopic spring rod 51 abuts against the triangular block 53, a clamping spring 54 is provided between the triangular block 53 and the clamping frame 50, the other end of the first rod 52 away from the telescopic spring rod 51 is movably abutted against a clamping rod 55, the clamping rod 55 is rotatably provided on the clamping frame 50 through a bearing in the middle, and a rubber layer in contact with the cabinet body is provided at the end of the clamping rod 55 away from the first rod 52. The electric telescopic rod 56 can drive the clamping piece 5 to stretch and retract in the horizontal direction, so as to clamp the cabinet body plate 100 of different widths.

[0068] The specific steps of clamping the cabinet body plate 100 are as follows: When the cabinet body plate 100 moves to the bending processing area, the clamping piece 5 is started, the electric telescopic rod 56 is energized and started, and the two clamping frames 50 are controlled to move close to the cabinet body plate 100. The telescopic spring rod 51 in the clamping frame 50 contacts the side wall of the cabinet body plate 100, and it will push the triangular block 53 to move (refer to Figure 7 As shown), the first rod 52 pushes the clamping rod 55 to rotate around the middle pivot point, so that one end of the clamping rod 55 provided with the rubber layer is tightly clamped on the surface of the cabinet body plate 100, realizing the clamping of the cabinet body plate 100, and the rubber layer can avoid scratching the surface of the cabinet body plate 100 during clamping.

[0069] When the clamping piece 5 completes the clamping of the cabinet body plate 100, the bending part 2 is started, as shown below: Referring to Figure 9 , Figure 10 As shown, the bending part 2 is provided on the bending platform 1, and includes two groups of upper and lower symmetric contact frames 21 and a bending plate 20 provided on the contact frame 21.

[0070] The bending plate 20 rotates from top to bottom, that is, the corners of the cabinet body plate 100 are folded, so that the whole cabinet body plate 100 presents a shape structure.

[0071] It needs to be explained here that, Figure 10Two sets of upper and lower symmetrical resistance frames 21 are arranged in the cabinet body plate 100, and the difference between the two sets of resistance frames 21 is that the resistance frame 21 located at the upper end is provided with a plurality of bending plates 20 and a driving mechanism for controlling the bending of the bending plates 20, and the resistance frame 21 located at the lower end is not provided with the bending plates 20 and the driving mechanism for controlling the bending of the bending plates 20.

[0072] The purpose of arranging two resistance frames 21 is that the resistance frame 21 located at the lower end of the cabinet body plate 100 abuts against the lower surface of the cabinet body plate 100, not only supporting the cabinet body plate 100, but also abutting against the crease to be bent of the cabinet body plate 100, avoiding deviation during bending. The resistance frame 21 located at the upper end of the cabinet body plate 100 abuts against the upper surface of the cabinet body plate 100, and the bending plate 20 at the upper end of the resistance frame 21 can bend the protruding part of the cabinet body plate 100 downward after clockwise rotation, The two resistance frames 21 can maximize the one-time forming of the cabinet body plate 100, avoiding the inclination of the crease.

[0073] Referring to Figure 10 , Figure 11 and Figure 12 , the resistance frame 21 comprises a plurality of resistance plates 210 distributed at equal intervals, and a scissor assembly 211 is arranged between adjacent resistance plates 210. The resistance plate 210 is slidingly installed along the length direction of two symmetrical telescopic plates 212. The telescopic plate 212 is installed with a fixed block 213 at the end away from the resistance plate 210. A plurality of bending plates 20 are rotatably arranged on the fixed blocks 213.

[0074] The bending part 2 is the core mechanism for realizing the bending forming of the cabinet body plate 100, comprising the resistance frame 21 and the bending plate 20 which are symmetrical and in a meandering structure, and can realize multi-angle bending of the cabinet body plate 100 and reduce the rebound.

[0075] Two adjacent resistance plates 210 are installed with horizontally telescopic bidirectional hydraulic cylinders 214, and two adjacent fixed blocks 213 in the width direction of the resistance frame 21 are provided with vertically telescopic bidirectional driving telescopic cylinders 215.

[0076] The resistance frame 21 is composed of a plurality of resistance plates 210 distributed at equal intervals, and the adjacent resistance plates 210 are connected through the scissor assembly 211, so that the resistance frame 21 can adapt to cabinet body plates 100 of different sizes. The adjacent resistance plates 210 are installed with bidirectional hydraulic cylinders 214, and the distance between the resistance plates 210 can be adjusted by driving the bidirectional hydraulic cylinders 214, so as to realize the adjustment of the overall size of the resistance frame 21. The fixed block 213 is installed with a bending plate 20 on one side through a hinge shaft, and the bending plate 20 can rotate around the hinge shaft to realize the bending operation of the cabinet body plate 100.

[0077] In order to realize the synchronous rotation of the bending plate 20, the application also provides a resistance frame 21, which is described with reference toFigure 13 、 Figure 14 and Figure 15 As shown in the figure, the fixed block 213 at the four corners of the abutment frame 21 is installed with a second gear 221, the second gear 221 is coaxially distributed with a first bevel gear 222, the first bevel gear 222 is meshed with a second bevel gear 223 rotatingly arranged on the fixed block 213, and a plurality of linkage columns 224 are arranged between the second bevel gears 223 at the four corners of the abutment frame 21, and the linkage columns 224 are connected with a plurality of bending plates 20 in the length direction of the abutment frame 21.

[0078] The fixed block 213 is further rotatingly arranged with a third gear 229 and a first gear 220 which are meshed with each other, the third gear 229 is meshed with the second gear 221, and the first gear 220 is provided with a plurality of telescopic columns 227 which are connected with a plurality of bending plates 20 in the width direction of the abutment frame 21.

[0079] The second gear 221 on one side is installed with a servo motor 225 arranged on the fixed block 213 through a shaft coupling.

[0080] When the servo motor 225 works, all the bending plates 20 can be driven to rotate synchronously through the gear set and the linkage column 224, so as to ensure the consistency of the bending angle.

[0081] It should be noted that the shaft coupling is a known structure, and its main purpose is to stably connect the servo motor 225 and the second gear 221.

[0082] The first gear 220, the second gear 221, the third gear 229, the first bevel gear 222 and the second bevel gear 223 are arranged to ensure the consistency of the bending of a plurality of bending plates 20 in the circumferential direction of the abutment frame 21.

[0083] The specific steps of the bending operation are as follows: The servo motor 225 is started, and the servo motor 225 drives the second gear 221 and the first bevel gear 222 connected therewith to rotate synchronously.

[0084] At this time, the second gear 221 controls the rotation of the telescopic column 227 through the gear transmission between the third gear 229 and the first gear 220, and when the telescopic column 227 rotates, the bending plates 20 arranged at equal intervals on the upper end of the telescopic column 227 rotate synchronously, and the bending plates 20 in the width direction of the abutment frame 21 rotate at the same time to bend the cabinet plate 100 in the width direction.

[0085] At the same time, the first bevel gear 222 on the second gear 221 rotates and drives the second bevel gear 223 to rotate, and the second bevel gear 223 drives the linkage column 224 to rotate, and the equally spaced bending plates 20 on the linkage column 224 rotate synchronously, and the several bending plates 20 in the length direction of the contact frame 21 rotate to bend the length direction of the cabinet plate 100.

[0086] Finally, the length direction and the width direction of the cabinet plate 100 are bent by the bending plate 20, that is, the bending work of the cabinet plate 100 is finally completed.

[0087] Looking back Figure 9 As shown, specifically, the bending platform 1 is provided with self-adapting telescopic spring sleeves 60, the top ends of which are connected with a support plate 61 for supporting the cabinet plate 100 conveyed. The self-adapting telescopic spring sleeves 60 can automatically adjust the height according to the weight of the cabinet plate 100 to ensure that the cabinet plate 100 is always in a horizontal state. The platform is also provided with a control hydraulic cylinder 62, the output end of which is connected with the fixed end of the bidirectional hydraulic cylinder 214 through a connecting plate 63, and the overall height of the contact frame 21 can be adjusted by the extension and contraction of the control hydraulic cylinder 62 to adapt to different bending requirements.

[0088] And it should be noted that in the initial state, the several contact plates 210 of the contact frame 21 are in a retracted state to reduce the floor area, and the control hydraulic cylinder 62 drives the contact plates 210 away from the cabinet plate 100, and after the front and back surfaces of the cabinet plate 100 are recognized and the wrong surface is flipped and corrected, the contact plates 210 are pressed to the top and bottom ends of the cabinet plate 100, and the contact frame 21 at the bottom end mainly functions to abut against the cabinet plate 100.

[0089] It should be noted that when the cabinet plate 100 rotates to adjust the front and back surfaces, it is away from the contact frame 21 and does not interfere with each other.

[0090] The contact plates 210 on the contact frame 21 are in a retracted state in the initial state (the contact plates 210 abut against each other at the head and tail), so that the size of the contact frame 21 is much smaller than the distance between the two control collars 42, so that the contact frame 21 can be away from the control collar 42 to ensure that the cabinet plate 100 in the control collar 42 is adjusted in the circumferential direction of the control collar 42.

[0091] After the position of the cabinet plate 100 is adjusted, the hydraulic cylinder 62 controls the contact frame 21 to approach the cabinet plate 100, and after the contact frame 21 abuts against the surface of the cabinet plate 100, the bidirectional hydraulic cylinder 214 controls the contact plates 210 to expand to a specified length through the scissor assembly 211, and at this time the bending plate 20 can bend the cabinet plate 100.

[0092] Further, in the initial state, the conveying device conveys the cabinet body plate 100 between the two control collars 42, at this time the adaptive telescopic spring sleeve 60 controls the support plate 61 to rise, so that the support plate 61 supports the cabinet body plate 100, if it is necessary to turn over the cabinet body plate 100, the clamping piece 5 clamps and turns over the cabinet body plate 100, in this process, the adaptive telescopic spring sleeve 60 controls the support plate 61 to descend, avoiding the interference of the support plate 61 to the turning over of the cabinet body plate 100.

[0093] When the front and back surfaces of the cabinet body plate 100 are correct, the support plate 61 supports it, and after the abutting frame 21 abuts against the upper and lower sides of the cabinet body plate 100, the support plate 61 is lowered downward, avoiding the interference of the support plate 61 to the unfolding of the abutting frame 21.

[0094] Referring to Figure 16 the figure is a flow chart of the cabinet body bending forming method, in particular: When working: first step, when the conveying device conveys the cabinet body plate 100 to be bent to the bending platform 1, the cabinet body plate 100 first enters the detection range of the identification part 3, and the identification part 3 starts to work, the detection block 32 on the auxiliary support 30 contacts the surface of the cabinet body plate 100, and the front and back surfaces of the cabinet body plate 100 are detected by the different roughness of the front and back surfaces, to automatically judge whether the cabinet body plate 100 is installed correctly.

[0095] If the direction of the cabinet body plate 100 is correct (the light surface and the rough surface meet the requirements), the conveying device conveys the cabinet body plate 100 to the upper end of the support plate 61, at this time the cabinet body plate 100 does not need to be adjusted, the cabinet body plate 100 continues to maintain the current state, the abutting plate 210 abuts against the upper and lower end surfaces of the cabinet body plate 100, and the bending work is carried out.

[0096] Second step: if it is found that the direction of the cabinet body plate 100 is wrong, it needs to be adjusted.

[0097] That is, the electric telescopic rod 56 is elongated, so that the rubber end provided at the end of the clamping rod 55 tightly contacts the surface of the cabinet body plate 100, to realize the clamping of the cabinet body plate 100.

[0098] Third step: after the cabinet body plate 100 is clamped, the electric sliding block 41 rotates one hundred and eighty degrees along the electric sliding rail 43, drives the cabinet body plate 100 to turn over, so that the direction of the cabinet body plate 100 is adjusted to be correct (the light surface and the rough surface meet the bending requirements). Then, the electric telescopic rod 56 is retracted, the clamping piece 5 releases the cabinet body plate 100, and the cabinet body plate 100 is placed on the support plate 61 again.

[0099] Fourth step: after the direction of the cabinet plate 100 is adjusted correctly, the bending part 2 starts to work. The hydraulic cylinder 62 is controlled to move, and the bidirectional hydraulic cylinder 214 and the abutting frame 21 are driven to move as a whole through the connecting plate 63, so that the abutting frame 21 is close to the cabinet plate 100.

[0100] The bidirectional hydraulic cylinder 214 works to adjust the distance between the adjacent abutting plates 210, and the telescopic plates 212 on the abutting plates 210 slide, so that the fixed blocks 213 drive the bending plates 20 to move to the creases of the cabinet plate 100, and the abutting frame 21 abuts against the creases of the cabinet plate 100.

[0101] The servo motor 225 is started, and the servo motor 225 controls all the bending plates 20 to rotate synchronously around the hinge shaft through the gear transmission system, so that the cabinet plate 100 is bent.

[0102] Fifth step: after the bending reaches the preset angle, the servo motor 225 stops working, the bending plate 20 stops rotating, and the bending plate 20 continues to maintain the extrusion state for a period of time, so as to further ensure the bending effect and prevent rebound.

[0103] After the bending is completed, the servo motor 225 is reversed to drive the bending plate 20 to reset, the hydraulic cylinder 62 is controlled to move to drive the abutting frame 21 to move away from the cabinet plate 100, the bidirectional hydraulic cylinder 214 and the telescopic plate 212 are reset, and the abutting frame 21 returns to the initial state.

[0104] Sixth step: then the clamping part 5 is actuated again to clamp and convey the cabinet plate 100 after bending to the next process, so that one bending operation is completed; then each part is reset, and the next cabinet plate 100 is waited to enter, and the above working steps are repeated.

[0105] The embodiments of the specific implementation mode are the preferred embodiments of the application, and are not limited to the protection scope of the application, so that: any equivalent changes made according to the structure, shape, principle of the application should be covered in the protection scope of the application.
