Description

Technical Field

[0001] The present invention relates to the technical field of bending equipment, and particularly to a bending device for the production of cabinet sheet metal. Background Art

[0002] In the process of cabinet sheet metal production, it includes a series of closely related and crucial links such as design, material preparation, processing, assembly, and quality control; among them, in the processing link, operations such as trimming, shearing, punching, and bending of the cabinet sheet material directly affect the final quality and performance of the cabinet.

[0003] When bending the cabinet sheet material, a bending center is required. In related technologies, for example, Chinese Patent Application CN115958095A discloses a flexible bending center for sheet material processing. The flexible bending center for sheet material processing includes a feeding platform. A plurality of support sleeves are provided on the top of the feeding platform. An installation groove is opened at the top of the support sleeve. A second spring is vertically provided in the installation groove. An installation block is provided at the top of the second spring. A ball is movably connected to the top of the installation block, so as to realize elastic support for the ball, and further effectively avoid rigid contact between the sheet material and the ball, which is beneficial to reducing the damage caused by collision between the sheet material and the ball.

[0004] However, the above-mentioned flexible bending center for sheet material processing also has some problems when in use: when the sheet material itself has surface defects such as convexity due to processing, transportation, etc., this defect will cause the bottom surface of the sheet material not to be flat, and then when the sheet material rotates, this defect will collide with all the balls in the same circumferential direction with high intensity. Since the collision effects received by these balls are similar, the service lives of these balls are all short, and then the replacement cycle of these balls is short, affecting the processing efficiency of the sheet material. Summary of the Invention

[0005] Based on this, it is necessary to provide a bending device for the production of cabinet sheet metal to solve the problem of low processing efficiency existing in the current bending process of cabinet sheet material.

[0006] The above object is achieved by the following technical solutions: A bending device for the production of cabinet sheet metal, the bending device for the production of cabinet sheet metal includes a feeding platform and a bending mechanism; Among them, a shrapnel is arranged on the feeding platform. The shrapnel has an arc-shaped structure. The number of the shrapnels is multiple. The multiple shrapnels are evenly divided into two groups. The two groups of shrapnels are symmetrically arranged with their concave surfaces facing each other. The multiple shrapnels in the same group are concentrically arranged and are arranged in the radial direction. At least two mounting seats are arranged on each shrapnel. All the mounting seats on the same shrapnel are arranged circumferentially. From the inside to the outside, the number of the mounting seats on different shrapnels increases in sequence. A ball is rotatably inserted into each mounting seat. The ball is configured to be able to form a rolling fit with the cabinet body plate. The rotation axis of the cabinet body plate coincides with the center of the shrapnel. The bending mechanism is configured to be able to bend the cabinet body plate.

[0007] Furthermore, at least two oil storage cavities are arranged inside each shrapnel. The oil storage cavities are correspondingly communicated with the mounting seats. Lubricating oil is stored in each oil storage cavity. The lubricating oil is configured to be able to lubricate the balls.

[0008] Furthermore, the bending device for manufacturing the cabinet body sheet metal further includes a one-way damping part. The one-way damping part is configured to be able to generate damping for the elastic reset of the shrapnel.

[0009] Furthermore, the one-way damping part includes a plurality of one-way damping cylinders. The one-way damping cylinders are correspondingly arranged with the mounting seats and are arranged between the shrapnel and the feeding platform. The output shaft of the one-way damping cylinder is arranged on the shrapnel.

[0010] Furthermore, the bending mechanism includes a guiding groove, a pressing arm frame, a rotating clamping part and a bending component. The guiding groove is arranged on the feeding platform. The two groups of shrapnels are symmetrically arranged on both sides of the guiding groove. The pressing arm frame is inserted into the guiding groove and can slide along the guiding groove. The rotating clamping part is arranged on the pressing arm frame and is configured to be able to clamp and rotate the cabinet body plate. The bending component is configured to be able to bend the cabinet body plate in the vertical direction.

[0011] Furthermore, the rotating clamping part includes two clamping blocks. The two clamping blocks are arranged in the vertical direction. One of the clamping blocks is arranged above the feeding platform and can move in the vertical direction and can also rotate around a first axis. The other clamping block is inserted into the guiding groove and can rotate around the first axis. The first axis extends in the vertical direction and coincides with the center of the shrapnel.

[0012] Further, the bending assembly includes a base, a pressing frame, and a bending portion. The base and the feeding platform are arranged adjacent to each other. The pressing frame is disposed on the base and can slide in the vertical direction, and is configured to press the cabinet body plate on the base. The bending portion is disposed on the base and can slide in the vertical direction, and is configured to form a stop fit with the cabinet body plate.

[0013] Further, the bending device for producing the cabinet body sheet metal further includes a driving mechanism, and the driving mechanism is configured to provide a driving force for the pressing arm frame to slide along the guiding groove.

[0014] Further, the bending device for producing the cabinet body sheet metal further includes a cleaning assembly, and the cleaning assembly is configured to clean the back surface of the cabinet body plate.

[0015] Further, the cleaning assembly includes a plurality of brushes, the plurality of brushes are arranged on the feeding platform, and the brush ends of the brushes are arranged facing the back surface of the cabinet body plate.

[0016] The beneficial effects of the present invention are as follows: During the use of the bending device for producing the cabinet body sheet metal provided by the present invention, when there is a downward convex defect on the plate and it rotates, the rotation trajectory of the downward convex defect coincides with the trajectory of the circle formed by two symmetrically arranged elastic pieces. Further, when the downward convex defect collides with the first ball, the first ball moves downward under the pushing of the downward convex defect, driving the elastic piece to synchronously undergo compressive deformation, so that the second ball adjacent to the first ball moves downward. Due to the hysteresis of the elastic reset of the elastic piece, when the downward convex defect collides with the second ball, the collision effect on the ball will be weakened. By analogy, the collision effects on most of the balls will be weakened, which is beneficial to reducing the damage caused by the collision between the cabinet body plate and the balls due to the deformation of the cabinet body plate. Further, the service life of the balls can be extended, the replacement frequency can be reduced, and the processing efficiency of the cabinet body plate can be ensured.

[0017] Further, by providing an oil storage cavity, when the elastic piece undergoes compressive deformation, the volume of the oil storage cavity will decrease, and the lubricating oil can flow out of the oil storage cavity, facilitating the lubrication of the balls. Thus, the frictional resistance when the balls rotate can be reduced, which is beneficial to reducing damages such as scratches and abrasions caused by friction between the balls and the cabinet body plate.

Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature.

[0023] As Figures 1 to 8 shown, the bending device for cabinet body sheet metal production provided by an embodiment of the present invention is used to bend the cabinet body sheet, and is configured to include a feeding platform 1 and a bending mechanism; wherein, a spring piece 3 is arranged on the feeding platform 1, the spring piece 3 is in an arc structure, the number of the spring pieces 3 is multiple, the multiple spring pieces 3 are evenly divided into two groups, the two groups of spring pieces 3 are symmetrically arranged with concave surfaces facing each other, the multiple spring pieces 3 in the same group are concentrically arranged and are arranged in a radial direction; at least two mounting seats 4 are arranged on each spring piece 3, all the mounting seats 4 on the same spring piece 3 are arranged circumferentially, and from inside to outside, the number of the mounting seats 4 on different spring pieces 3 increases in sequence; a ball 5 is rotatably inserted on each mounting seat 4, and the ball 5 is configured to be able to form a rolling fit with the cabinet body sheet; the rotation axis of the cabinet body sheet coincides with the center of the spring piece 3; the bending mechanism is configured to be able to bend the cabinet body sheet.

[0024] Specifically in this embodiment, the cross-sectional shape of the elastic piece 3 is set to an inverted U shape, and it is arranged at the top of the feeding platform 1 with the opening facing downwards. Taking the number of elastic pieces 3 being ten as an example, the ten elastic pieces 3 are evenly divided into two groups. The five elastic pieces 3 in the same group are concentrically arranged and are arranged along the radial direction from the inside out or from the outside in. The two groups of elastic pieces 3 are symmetrically arranged with their concave surfaces facing each other, so that any two symmetrically arranged elastic pieces 3 can form a circular shape, and the center of the elastic piece 3 coincides with the rotation axis of the cabinet body board, ensuring that the circular shape formed by any two symmetrically arranged elastic pieces 3 can coincide with the rotation trajectory of the convex defect on the board. The mounting seat 4 is vertically arranged on the top of the elastic piece 3. The ball 5 is rotatably inserted at the top of the mounting seat 4 to ensure rolling cooperation with the cabinet body board.

[0025] During the use process, when there is a convex defect on the board and it rotates, the rotation trajectory of the convex defect coincides with the circular shape formed by two symmetrically arranged elastic pieces 3. Then, when the convex defect collides with the first ball 5, under the pushing of the convex defect, the first ball 5 will move downward in the vertical direction. When the first ball 5 moves, it synchronously drives the elastic piece 3 to undergo compressive deformation through the mounting seat 4, causing the second ball 5 adjacent to the first ball 5 to also move downward in the vertical direction at the same time. Due to the hysteresis effect of the elastic reset of the elastic piece 3, when the convex defect collides with the second ball 5, since the second ball 5 has not been fully reset, it has already generated a downward displacement in the vertical direction in advance, which is equivalent to reserving a certain buffer space, and the collision force it receives will be significantly weakened compared to the case without this structural design. And so on, in the entire circumferential direction, most of the subsequent balls 5 that collide with the convex defect will have the collision force they receive weakened in turn due to the buffering effect of the previous balls 5 and the collaborative deformation of the elastic piece 3. This is beneficial to reducing the damage caused by the collision between the cabinet body board and the balls 5 due to the deformation (convex defect) of the cabinet body board, and then can extend the service life of the balls 5, reduce the replacement frequency, and ensure the processing efficiency of the cabinet body board.

[0026] In some embodiments, to improve the lubrication effect on the balls 5, at least two oil storage cavities 301 are arranged inside each elastic piece 3. The oil storage cavities 301 are correspondingly communicated with the mounting seat 4, and lubricating oil is stored in each oil storage cavity 301. The lubricating oil is configured to lubricate the balls 5.

[0027] Specifically in this embodiment, as Figure 8As shown, the oil storage chamber 301 is arranged inside the top of the spring piece 3 ; a flow channel 401 is arranged on the mounting seat 4 , and the flow channel 401 is connected to the oil storage chamber 301 and the ball 5 at the same time. In this way, when the spring piece 3 is compressed and deformed under the action of external forces such as the gravity of the cabinet plate and the pressure generated during the processing, the spatial layout of the oil storage chamber 301 will change accordingly, and its volume will decrease accordingly; according to the principles of fluid mechanics, during this volume change process, the lubricating oil stored in the oil storage chamber 301 will flow out of the oil storage chamber 301 due to the pressure difference, and the lubricating oil flowing out can accurately and effectively act on the ball 5 through the flow channel 401 to achieve full lubrication of the ball 5, thereby significantly reducing the friction resistance of the ball 5 during the rotation process. The smaller friction resistance makes the ball 5 rotate more smoothly, greatly reducing the risk of material performance degradation and increased wear of the ball 5 caused by frictional heat; on the other hand, the relative movement between the ball 5 and the cabinet plate is made more stable and smooth, which is not only conducive to reducing scratches, wear and other damages caused by friction between the ball 5 and the cabinet plate, but also improves the surface quality of the cabinet plate; at the same time, it can also significantly improve the positioning accuracy and movement stability of the cabinet plate during the processing.

[0028] In other embodiments, in order to improve the weakening effect of the collision effect on the ball 5, the bending device set for the production of cabinet sheet metal also includes a one-way damping part, which is configured to damp the elastic reset of the spring 3. In this way, when the spring 3 is compressed and deformed, the reset speed of the spring 3 will be slowed down under the action of the one-way damping part, so that the speed of the next ball 5 moving upward will be reduced, and then the distance that the ball 5 moves upward is smaller, so that when the lower convex defect collides with the ball 5, the ball 5 has already produced a large downward displacement in the vertical direction in advance, which is equivalent to reserving a larger buffer space, and the collision effect it receives can be further weakened. By analogy, in the entire circumferential direction, most of the balls 5 that collide with the lower convex defect in the future will have their respective collision effects further weakened in turn due to the buffering effect of the previous ball 5 and the coordinated deformation of the spring 3.

[0029] Furthermore, the one-way damping part can be configured to include multiple one-way damping cylinders 8, which are correspondingly arranged with the mounting seat 4 and arranged between the spring sheet 3 and the feeding platform 1, and the output shaft of the one-way damping cylinder 8 is arranged on the spring sheet 3.

[0030] Specifically, when the one-way damping cylinder 8 is installed, it can be vertically placed between the elastic sheet 3 and the feeding platform 1. From the perspective of the mechanical conduction path, such a setting enables the one-way damping cylinder 8 to directly and efficiently receive the acting force generated during the elastic resetting process of the elastic sheet 3 and convert it into a damping force. Moreover, due to the one-way characteristic of the one-way damping cylinder 8, it only exerts a damping effect in the resetting direction of the elastic sheet 3 and hardly generates additional resistance in the direction of the elastic sheet 3 being compressed and deformed, thus ensuring that the flexibility of the elastic sheet 3 during normal compression work is not affected. Considering the installation convenience and stability, the corresponding setting of the one-way damping cylinder 8 and the mounting seat 4 makes the installation process of the entire one-way damping part simple and firm, and it can be stably integrated into the existing structural system of the bending device. In the long-term high-intensity production operation environment, it can still operate reliably, providing stable and continuous support for the elastic reset damping control of the elastic sheet 3, thereby comprehensively enhancing the weakening effect on the collision force received by the ball 5 and greatly enhancing the ability of the bending device to cope with complex working conditions such as the convex defect of the cabinet body board.

[0031] More specifically, the one-way damping cylinder 8 is set to be composed of a cylinder body and an output shaft. The cylinder body is arranged on the top of the feeding platform 1, and damping liquid is filled in the damping cylinder. The output shaft is of a T-shaped structure, and its large end is slidably inserted into the cylinder body and forms a piston-like structure with the cylinder body. The small end penetrates through the top of the cylinder body and is arranged at the bottom of the elastic sheet 3. A plurality of first holes and a plurality of second holes are penetrated on the large end surface of the output shaft. The diameter of the first holes is larger than that of the second holes. A one-way valve is inserted in each first hole, and the opening direction of the one-way valve is from top to bottom, ensuring that when the elastic sheet 3 is pressed and moves downward, the output shaft moves synchronously from top to bottom, and the one-way valve is in an open state, so that the one-way damping cylinder 8 hardly generates damping on the movement of the elastic sheet 3. When the elastic sheet 3 elastically resets, the output shaft moves synchronously from bottom to top, and the one-way valve is in a closed state, so that the one-way damping cylinder 8 generates a large damping on the movement of the elastic sheet 3.

[0032] In some other embodiments, the bending mechanism is set to include a guide groove 201, a pressing arm frame 202, a rotating clamping part 203, and a bending component 204. The guide groove 201 is arranged on the feeding platform 1; two groups of elastic sheets 3 are symmetrically arranged on both sides of the guide groove 201; the pressing arm frame 202 is inserted into the guide groove 201 and can slide along the guide groove 201; the rotating clamping part 203 is arranged on the pressing arm frame 202 and is configured to be able to clamp and rotate the cabinet body board; the bending component 204 is configured to be able to bend the cabinet body board in the vertical direction.

[0033] Specifically in this embodiment, the guide groove 201 is set to be a strip-shaped structure, and extends along the front-rear direction and is horizontally arranged on the top of the feeding platform 1; both ends of the elastic sheet 3 coincide with the guide groove 201 to ensure that the balls 5 can be distributed circumferentially as much as possible; the pressing wall frame is set to be a U-shaped structure, and the opening is horizontally facing backward.

[0034] During the use process, first place the cabinet body board on the area where the elastic piece 3 is located on the feeding platform 1, then clamp the cabinet body board by rotating the clamping part 203, and then drive the cabinet body board to rotate by rotating the clamping part 203 so that the first side to be bent of the cabinet body board is in a proper position; then drive the pressing arm frame 202 to slide along the guiding groove 201. When the pressing arm frame 202 moves, drive the cabinet body board to move to a proper position by rotating the clamping part 203; then bend the first side to be bent of the cabinet body board vertically by the bending component 204.

[0035] After the first side to be bent of the cabinet body board is bent, drive the pressing arm frame 202 to slide along the guiding groove 201. When the pressing arm frame 202 moves, drive the cabinet body board to move to the area where the elastic piece 3 is located on the feeding platform 1 by rotating the clamping part 203, and then drive the cabinet body board to rotate by rotating the clamping part 203 so that the second side to be bent of the cabinet body board is in a proper position; then drive the pressing arm frame 202 to slide along the guiding groove 201. When the pressing arm frame 202 moves, drive the cabinet body board to move to a proper position by rotating the clamping part 203; then bend the second side to be bent of the cabinet body board vertically by the bending component 204.

[0036] Repeat the above process until all the sides to be bent on the cabinet body board are bent.

[0037] Further, the rotating clamping part 203 is arranged to include two clamping blocks 2031. The two clamping blocks 2031 are arranged vertically. One of the clamping blocks 2031 is arranged above the feeding platform 1 and can move vertically and can also rotate around the first axis. The other clamping block 2031 is inserted into the guiding groove 201 and can rotate around the first axis; the first axis extends vertically and coincides with the center of the elastic piece 3.

[0038] Specifically, one of the clamping blocks 2031 is arranged on the rear side wall surface of the upper cantilever of the pressing arm frame 202, and the clamping surface of this clamping block 2031 faces downward to ensure that it can press down on the top of the cabinet body board from top to bottom; the other clamping block 2031 is arranged on the top of the lower cantilever of the pressing arm frame 202, and the clamping surface of this clamping block 2031 faces upward to ensure that it can support upward on the bottom of the cabinet body board.

[0039] To facilitate providing a driving force for the clamping block 2031 provided on the upper cantilever of the pressing arm frame 202 to be able to move vertically and rotate around the first axis, the rotating clamping portion 203 is further provided with a first driving motor 2032 and a telescopic rod 2033. The first driving motor 2032 is provided on the rear side wall surface of the upper cantilever of the pressing arm frame 202, and the motor shaft of the first driving motor 2032 is arranged vertically downward; the telescopic rod 2033 extends vertically and can be telescopic. The fixed end of the telescopic rod 2033 is provided on the motor shaft of the first driving motor 2032, and the moving end is provided on the clamping block 2031; the first axis coincides with the axis of the motor shaft of the first driving motor 2032, and the center of the elastic piece 3 coincides with the first axis, ensuring that the rotation axis of the cabinet body plate coincides with the center of the elastic piece 3.

[0040] During the use process, first place the cabinet body plate on the area where the elastic piece 3 is located on the feeding platform 1, then extend the telescopic rod 2033. The telescopic rod 2033 drives the clamping block 2031 located above to move downward, and then clamp the cabinet body plate through the clamping block 2031 located below; then start the first driving motor 2032. The first driving motor 2032 drives the telescopic rod 2033 to rotate, and the telescopic rod 2033 drives the cabinet body plate to rotate through the clamping of the two clamping blocks 2031, so that the edge to be bent of the cabinet body plate is in a suitable position.

[0041] Optionally, the telescopic rod 2033 can be driven to extend or shorten by a hydraulic method; it can also be driven to extend or shorten by a pneumatic method; it can also be driven to extend or shorten by an electric method.

[0042] Optionally, an elastic friction portion is provided on the clamping surface of the clamping block 2031. The elastic friction portion is made of rubber material, so as to increase the friction force between the clamping block 2031 and the cabinet body plate by increasing the friction coefficient, and improve the stability when clamping the cabinet body plate.

[0043] Optionally, a suction cup is provided on the clamping surface of the clamping block 2031 to ensure that when clamping the cabinet body plate, an additional adsorption force can be generated by the atmospheric pressure, further enhancing the reliability of the clamping; in addition, it can also avoid hard clamping of the cabinet body plate and reduce damage to the surface of the cabinet body plate.

[0044] Furthermore, the bending assembly 204 is provided to include a base 2041, a pressing frame 2042 and a bending portion 2043. The base 2041 is closely arranged with the feeding platform 1; the pressing frame 2042 is provided on the base 2041 and can slide vertically, and is configured to be able to press the cabinet body plate on the base 2041; the bending portion 2043 is provided on the base 2041 and can slide vertically, and is configured to be able to form a stop fit with the cabinet body plate.

[0045] Specifically, as Figure 1 shown, the base 2041 is located at the rear side of the feeding platform 1; the pressing frame 2042 is arranged on the front side wall of the base 2041; to facilitate providing the driving force for the pressing frame 2042 to slide in the vertical direction, the bending assembly 204 is further configured to include a first guide rail 2044 and a first driving cylinder 2045. The first guide rail 2044 extends in the up and down direction and is arranged on the front side wall of the base 2041; the pressing frame 2042 is slidably sleeved on the first guide rail 2044; the first driving cylinder 2045 is arranged on the top of the base 2041, and the output shaft faces downward and is fixedly arranged on the pressing frame 2042, ensuring that the pressing frame 2042 can be driven to slide along the first guide rail 2044.

[0046] Optionally, the number of the first guide rails 2044 and the first driving cylinders 2045 can both be set to two. The two first guide rails 2044 are arranged at intervals in the left and right directions; the two first driving cylinders 2045 are arranged at intervals in the left and right directions, and the output shafts are simultaneously arranged on the pressing frame 2042, ensuring that the pressing frame 2042 can be driven to slide along the first guide rail 2044 more stably.

[0047] Optionally, the first driving cylinder 2045 can be set to any one of a hydraulic cylinder, a pneumatic cylinder or an electric cylinder.

[0048] More specifically, the bending part 2043 is arranged on the front side wall of the base 2041, and is located below the pressing frame 2042 and at the rear side of the pressing frame 2042, ensuring that the bending part 2043 and the pressing frame 2042 do not interfere during movement. The bending part 2043 further has an upper folding knife 20431 and a lower folding knife 20432. The upper folding knife 20431 and the lower folding knife 20432 are both arranged on the front side wall of the bending part 2043 and are arranged at intervals in the up and down direction. The lower folding knife 20432 is located below the upper folding knife 20431. The upper folding knife 20431 and the lower folding knife 20432 are both arranged in a strip structure and both extend in the left and right directions. The upper folding knife 20431 is configured to be able to bend the cabinet body plate from top to bottom, and the lower folding knife 20432 is configured to be able to bend the cabinet body plate from bottom to top; to facilitate providing the driving force for the bending part 2043 to slide in the vertical direction, the bending assembly 204 is further configured to include a second driving cylinder. The second driving cylinder is arranged on the base 2041, and the output shaft faces upward and is fixedly arranged on the bending part 2043, ensuring that the bending part 2043 can be driven to move in the vertical direction.

[0049] Optionally, the second driving cylinder can be set to any one of a hydraulic cylinder, a pneumatic cylinder or an electric cylinder.

[0050] During use, when the cabinet body plate rotates and extends in the left-right direction of the edge to be bent, it drives the pressing arm frame 202 to slide along the guiding groove 201 towards the direction close to the base 2041. When the pressing arm frame 202 moves, it synchronously drives the cabinet body plate to move until the edge to be bent is located above the lower folding knife 20432. Then, the first driving cylinder 2045 is started, and the output shaft of the first driving cylinder 2045 extends, synchronously driving the pressing frame 2042 to move downward until the pressing frame 2042 fixes the cabinet body plate on the base 2041. Then, the second driving cylinder is started, and the output shaft of the second driving cylinder extends, synchronously driving the bending part 2043 to move upward, and bending the edge to be bent upward through the lower folding knife 20432.

[0051] Furthermore, the bending device for cabinet body sheet metal production is further provided with a driving mechanism 6, and the driving mechanism 6 is configured to be able to provide the driving force for the pressing arm frame 202 to slide along the guiding groove 201.

[0052] Specifically, the driving mechanism 6 can be set to include a second guide rail 601, a lead screw 602 and a second driving motor 603. The second guide rail 601 is inserted in parallel in the guiding groove 201; as Figure 5 shown, the lead screw 602 is arranged in parallel on the top of the second guide rail 601 and can rotate around its own axis; the pressing arm frame 202 is arranged on the top of the second guide rail 601 and forms a sliding fit with the second guide rail 601. The pressing arm frame 202 is simultaneously sleeved on the lead screw 602 and forms a transmission fit with the lead screw 602, ensuring that when the lead screw 602 rotates, the pressing arm frame 202 can slide along the guiding groove 201 under the guidance of the second guide rail 601; the second driving motor 603 is arranged on the top of the second guide rail 601, and the motor shaft of the second driving motor 603 is coaxial and fixedly connected with the lead screw 602, ensuring that the lead screw 602 can be driven to rotate.

[0053] During use, the second driving motor 603 is started, and the second driving motor 603 drives the lead screw 602 to rotate. When the lead screw 602 rotates, it drives the pressing arm frame 202 to slide along the guiding groove 201 under the guidance of the second guide rail 601.

[0054] In some other embodiments, in the processing flow of the cabinet body plate, its back surface is extremely likely to be contaminated with various impurities such as metal chips, dust particles, oil stains, etc. during the previous processes of material handling, storage, edge cutting, punching, etc.; the existence of these impurities will not only affect the surface quality of the cabinet body plate during the bending process, but may also interfere with the fitting degree and positioning accuracy between the cabinet body plate and the bending device, thereby having an adverse impact on the quality of the final cabinet product. To solve this problem, the bending device for cabinet body sheet metal production is further provided with a cleaning component 7, and the cleaning component 7 is configured to be able to clean the back surface of the cabinet body plate.

[0055] Further, the cleaning component 7 is set to include a plurality of brushes 701. The plurality of brushes 701 are arranged on the feeding platform 1, and the brush ends of the brushes 701 are arranged facing the back surface of the cabinet body board. In this way, when the cabinet body board moves on the feeding platform 1, the back surface of the cabinet body board will continuously come into contact with the brush ends of the brushes 701. As the cabinet body board moves, the brushes 701, with their soft and elastic bristles, can effectively scrape off impurities such as metal debris and dust particles attached to the back surface of the cabinet body board. For sticky impurities such as oil stains, the continuous brushing of the brushes 701 can break their attachment structure.

[0056] Optionally, in cooperation with a dust suction or air blowing device that may be set subsequently, more thorough cleaning can be achieved.

[0057] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0058] The above-described embodiments only represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
