Description

Technical Field

[0001] The present invention relates to the technical field of bending machines, and in particular to a plate bending device and method for processing box-type power distribution cabinets. Background Art

[0002] Sheet bending devices are devices used to bend and fold sheets, and are widely used in metal processing, decorative panel manufacturing and other fields;

[0003] For example, the prior art publication number CN116748343A is titled: A patent for an electro-hydraulic servo anti-deformation control system for a CNC bending machine. This patent activates a conversion component by triggering a hydraulic component to apply hydraulic oil pressure until the bending die is pressed down by the bending tool and contacts the unloading table. The bending tool stops moving downward, and the conversion component switches the oil inlet from the first oil port to the second oil port, causing the bending tool to move upward, thereby improving the processing quality of the bent workpiece.

[0004] Although the above-mentioned prior art optimizes the structure of the bending machine and improves the quality of the bent workpiece, the prior art does not perform structural optimization for workpieces with larger areas. Therefore, during bending, a portion of the plate to be processed is in a suspended state, and this portion of the plate is prone to falling, causing deformation of the plate. Therefore, improvements need to be made to this problem. Summary of the Invention

[0005] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and title of this application to avoid obscuring the purpose of this section, the abstract and the title of the invention, and such simplifications or omissions should not be used to limit the scope of the present invention.

[0006] The present invention provides a plate bending device and method for processing box-type power distribution cabinets, which can solve the problem in the prior art that the flat part of the plate is easily deformed when bending the plate. The specific solution is as follows:

[0007] On the one hand, the present invention provides a plate bending device for processing a box-type power distribution cabinet, comprising a bending machine body, an upper mold and a lower mold. When the upper mold is pressed down, the upper mold and the lower mold cooperate to bend the bending part of the plate to be processed. The device also includes a lifting assembly, which includes:

[0008] The lifting column is slidably mounted on the top of the processing table and moves up and down driven by the driving source;

[0009] The first pressing cylinder is arranged on one side of the top end of the lifting column and can rotate;

[0010] The second pressing cylinder is arranged above the first pressing cylinder and can rotate on its own and around the first pressing cylinder. The first pressing cylinder and the second pressing cylinder clamp the plate to be processed;

[0011] Among them, when the flat part of the plate to be processed is warped during the bending process, the first clamping cylinder and the second clamping cylinder clamp the warped part and rise synchronously to provide support for the flat part of the plate to be processed. By arranging a lifting component under the plate to be processed, the warped part formed after the plate to be processed is bent can be fully supported by the lifting component, thereby ensuring that the warped part of the plate to be processed will not be deformed due to the influence of gravity, thereby ensuring the flatness of the plate to be processed after bending.

[0012] Preferably, a controller is fixedly installed on the outside of the bending machine body, and an industrial computer, control buttons and a display screen are integrated in the controller.

[0013] Preferably, it also includes:

[0014] A lower pressing member, the lower pressing member is located above the processing area;

[0015] A clamping tool is fixedly connected to the bottom of the lower pressing member, and the upper mold is fixedly installed on the bottom of the clamping tool;

[0016] A hydraulic rod is fixedly connected to the top of the lower pressure member, and the top end of the hydraulic rod is fixedly connected to the inside of the bending machine body. A foot button is also provided at one end of the bending machine body, and the foot button is used to control the hydraulic rod.

[0017] Preferably, it also includes:

[0018] The support column is installed on one side of the lower mold and can move up and down driven by the driving source.

[0019] Preferably, it also includes:

[0020] The support plate is installed on the other side of the lower mold and is used to provide support for the other end of the plate to be processed. By arranging support columns and support plates at both ends of the lower mold, when the plate to be processed is bent, the support columns and support plates can respectively provide support for both ends of the plate to be processed, thereby supporting the middle part of the plate to be processed, preventing the middle part of the plate to be processed from sinking under the action of gravity, and further improving the processing quality of the plate to be processed.

[0021] Preferably, it also includes:

[0022] A first sleeve rod, one end of which is fixed to one side of the top end of the lifting column and is inserted into the interior of the first pressing cylinder;

[0023] a second sleeve rod, disposed above the first sleeve rod and passing through the interior of the second compression cylinder, the second sleeve rod being capable of rotating around the first sleeve rod;

[0024] a hinged member, the bottom of which is hingedly connected to one end of the first set of rods, and the top of which is fixedly connected to the end of the second set of rods;

[0025] Among them, as the lifting column and the lifting height of the plate to be processed rise synchronously, the hinge also rotates with the inclination angle of the plate to be processed, so that the surface formed by the central axis of the first clamping cylinder and the second clamping cylinder is perpendicular to the surface of the plate to be processed.

[0026] Preferably, it also includes:

[0027] a limiting rod fixedly connected to the outer wall of the hinge;

[0028] A limiting sleeve is fixedly connected to the outer wall of the lifting column, and the limiting rod is slidably connected to the limiting sleeve;

[0029] The spring is sleeved on the outer wall of the limiting rod, and the two ends of the spring are respectively fixedly connected to the outer wall of the hinge and the outer wall of the limiting sleeve.

[0030] Preferably, it also includes:

[0031] Sixth gear;

[0032] a third motor, fixedly mounted on the top of the lifting column, wherein the output shaft of the third motor is fixedly connected to the sixth gear;

[0033] a seventh gear, fixedly connected to one end of the first pressing cylinder, the seventh gear meshing with the sixth gear;

[0034] a fourth gear fixedly connected to an end portion of the first compression cylinder;

[0035] The fifth gear is fixedly connected to the end of the second pressing cylinder, and the fifth gear is meshed with the fourth gear.

[0036] Preferably, it also includes:

[0037] A receiving groove is provided on the top of the processing table;

[0038] An extrusion portion is provided on the inner wall of the receiving groove and is located corresponding to the hinge;

[0039] Among them, when the lifting column drops to the lowest point, the bottom of the hinge and the extrusion part squeeze each other, thereby prompting the hinge to rotate from an inclined state to a vertical state. In the vertical state, the sixth gear is driven to rotate by the third motor, and the first clamping cylinder and the second clamping cylinder rotate synchronously and oppositely. When the plate to be processed is fed, the plate to be processed is conveyed. By lowering the lifting assembly to the lowest position, the first clamping cylinder and the second clamping cylinder can clamp the plate to be processed in a horizontal state, and then convey the plate to be processed to the specified position, so that there is no need to adjust the bending position of the plate to be processed separately, which is more convenient to use.

[0040] A plate bending method for processing a box-type power distribution cabinet comprises the following steps:

[0041] S1. Place the plate to be bent on the processing table and push it slightly to the rear of the bending machine body so that the rear of the plate to be processed is clamped by the first pressing cylinder and the second pressing cylinder;

[0042] S2. Move the bending part of the plate to be processed to the top of the lower die. The upper die moves downward under the drive source, and squeezes the lower die to bend the plate to be processed.

[0043] S3. During the bending process of the plate to be processed, the driving source drives the lifting column and the tilted portion of the plate to be processed to rise synchronously, and the second pressing cylinder rotates around the central axis of the first pressing cylinder, so that the second pressing cylinder rotates synchronously with the tilting angle of the plate to be processed;

[0044] S4. After the bending of the plate to be processed is completed, the lifting column drops to the lowest point, the plate to be processed is taken out, and the bending work is completed.

[0045] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0046] 1. By setting a lifting component under the plate to be processed, when the plate to be processed is bent, the raised part formed can be fully supported by the lifting component, thereby ensuring that the raised part of the plate to be processed will not be deformed due to gravity, thereby ensuring the flatness of the plate to be processed after bending.

[0047] 2. By lowering the lifting assembly to the lowest position, the first pressing cylinder and the second pressing cylinder can clamp the plate to be processed in a horizontal state, and then transport the plate to be processed to the specified position, so that there is no need to adjust the bending position of the plate to be processed separately, which is more convenient to use.

[0048] 3. By arranging support columns and support plates at both ends of the lower mold, when the plate to be processed is bent, the support columns and support plates can provide support to both ends of the plate to be processed respectively, thereby supporting the middle part of the plate to be processed, preventing the middle part of the plate to be processed from sinking under the action of gravity, and further improving the processing quality of the plate to be processed.

[0049] 4. By setting an extrusion part, when the lifting column drops to the lowest point, the bottom of the hinge and the extrusion part squeeze each other, thereby prompting the hinge to rotate from an inclined state to a vertical state. In the vertical state, the sixth gear is driven to rotate by the third motor, and the sixth gear drives the seventh gear to rotate, thereby rotating the first clamping cylinder. Due to the meshing action of the fourth gear and the fifth gear, the first clamping cylinder and the second clamping cylinder rotate synchronously and oppositely, thereby conveying the sheet to be processed when feeding before the sheet to be processed is bent.

[0050] Other features and advantages of the present invention will be described in the following description, and part of them will become obvious from the description, or will be understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the written description and the accompanying drawings.

[0073] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used to explain the principles of the present invention together with the embodiments of the present invention.

[0074] Example 1: Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, this embodiment provides a plate bending device for processing a box-type power distribution cabinet, which is used to bend a plate 200 to be processed, including:

[0075] The bending machine body 101 is placed on the ground. A controller 102 is fixedly installed on the outside of the bending machine body 101. The controller 102 integrates an industrial computer, control buttons and a display screen. A processing table 103 is provided below the bending machine body 101. The processing table 103 is used to carry the plate 200 to be processed. A processing area 109 is provided in the middle of the bending machine body 101. The processing area 109 is located above the processing table 103 and in the middle of the entire bending machine body 101. The front and rear ends of the processing area 109 are connected to the front and rear ends of the bending machine body 101.

[0076] The lower pressing member 104 is located above the processing area 109. The bottom of the lower pressing member 104 is fixedly connected to the clamping tool 105. The bottom of the clamping tool 105 is provided with an upper mold 106. The upper mold 106 is installed on the clamping tool 105. A lower mold 107 is provided at the bottom of the processing area 109. The position of the lower mold 107 corresponds to that of the upper mold 106. When the two are close to each other, the plate 200 to be processed can be squeezed to form a bending angle. The top of the lower pressing member 104 is fixedly connected to a hydraulic rod 108. The top of the hydraulic rod 108 is fixedly connected to the inside of the bending machine body 101. A foot button (not shown in the figure) is also provided at one end of the bending machine body 101. The foot button is used to control the hydraulic rod 108.

[0077] like Figure 5 、 Figure 6 As shown, in this embodiment, in order to prevent the flat portion of the plate 200 to be processed from rotating with the bent portion as a fulcrum under the action of gravity after being bent, thereby causing the flat portion of the plate 200 to be processed to be deformed, a lifting assembly 300 is further provided on the processing table 103. The lifting assembly 300 is used to support the plate 200 to be processed after being bent.

[0078] like Figure 7 、 Figure 8As shown, when the lifting assembly 300 changes with the bending angle of the plate 200 to be processed, the lifting assembly 300 can actively follow the plate 200 to be processed and move upward synchronously, thereby providing real-time support for the flat part of the plate 200 to be processed, thereby preventing the flat part of the plate 200 to be processed from deforming.

[0079] like Figure 9 、 Figure 10 、 Figure 11 As shown, in this embodiment, the lifting assembly 300 includes:

[0080] A first rack 301 is mounted on one side of the lower mold 107. A support column 302 is provided on the top of the first rack 301. A receiving groove matching the support column 302 is provided on the top of the processing table 103. The receiving groove can completely wrap the support column 302. Therefore, when the first rack 301 drops to the lowest point, the top of the support column 302 is lower than the top surface of the processing table 103. The support column 302 and the first rack 301 are integrally formed or connected by welding.

[0081] The first gear 303 is provided on one side of the first rack 301 and is engaged with the first rack 301. The first gear 303 is rotatably mounted inside the processing table 103.

[0082] The rotating shaft 312 is fixedly connected to the middle of the first gear 303 and is rotatably connected to the interior of the processing table 103;

[0083] The first bevel gear 304 is fixedly connected to the rotating shaft 312;

[0084] The second bevel gear 305 is arranged perpendicular to the first bevel gear 304 and meshes with the first bevel gear 304;

[0085] The first motor 306 is fixedly installed inside the processing table 103. The top output shaft of the first motor 306 is fixedly connected to the second bevel gear 305. Therefore, when the first motor 306 is started, it can drive the second bevel gear 305 to rotate. Since the second bevel gear 305 and the first bevel gear 304 rotate synchronously, the first bevel gear 304 then drives the entire rotating shaft 312 to rotate. When the rotating shaft 312 rotates, the first gear 303 on the rotating shaft 312 drives the first rack 301 to rise, thereby allowing the support column 302 on the top of the first rack 301 to press against the bottom of the plate 200 to be processed, thereby providing a supporting force for the plate 200 to be processed;

[0086] The support plate 307 is installed on the other side of the lower mold 107 and is used to provide support for the other end of the plate 200 to be processed. The bottom of the support plate 307 is fixedly connected to an arc block 308, which is slidably connected to the processing table 103. The middle part of the arc block 308 is fixedly connected to a second rack 309. The second rack 309 is arc-shaped. The central axis of the arc block 308 and the second rack 309 coincides with the bending point of the lower mold 107 and the upper mold 106. Therefore, when the support plate 307 rotates, it can always form surface contact with the ground of the plate 200 to be processed, providing better support force;

[0087] A second gear 310 is provided on one side of the second rack 309 and is engaged with the second rack 309;

[0088] The second motor 311 is fixedly installed inside the processing table 103. The output shaft of the second motor 311 is fixedly connected to one end of the second gear 310. When the second motor 311 is started, it can drive the second gear 310 to rotate, so that the second gear 310 drives the second rack 309 to rotate upward until the support plate 307 supports the bottom of the plate 200 to be processed, thereby providing support for the other end of the plate 200 to be processed.

[0089] like Figure 12 、 Figure 13 、 Figure 14 As shown, in this embodiment, the lifting assembly 300 further includes:

[0090] A lifting column 313 is slidably mounted on top of the processing table 103;

[0091] The first pressing cylinder 314 is provided on one side of the top of the lifting column 313 and is capable of self-rotation;

[0092] The second pressing cylinder 315 is disposed above the first pressing cylinder 314 and is capable of rotating on its own and around the first pressing cylinder 314. The outer walls of the second pressing cylinder 315 and the first pressing cylinder 314 are both made of soft materials (such as rubber or sponge), so as to clamp the plate 200 to be processed;

[0093] A first sleeve rod 316, one end of which is fixedly connected to one side of the top end of the lifting column 313 and is inserted into the interior of the first pressing cylinder 314;

[0094] The second rod 317 is disposed above the first rod 316 and passes through the interior of the second compression cylinder 315. The second rod 317 can rotate around the first rod 316.

[0095] The fourth gear 320 is fixedly connected to the end of the first pressing cylinder 314;

[0096] The fifth gear 321 is fixedly connected to the end of the second pressing cylinder 315 and meshes with the fourth gear 320;

[0097] A hinged member 322, the bottom of which is hinged to one end of the first set of rods 316, and the top of which is fixedly connected to the end of the second set of rods 317;

[0098] A limiting rod 323 is fixedly connected to the outer wall of the hinge 322;

[0099] The limiting sleeve 324 is fixedly connected to the outer wall of the lifting column 313. The limiting rod 323 is slidably connected to the limiting sleeve 324, and a protrusion is provided at the end of the limiting rod 323 to prevent the limiting rod 323 from being separated from the limiting sleeve 324;

[0100] The spring 325 is sleeved on the outer wall of the limiting rod 323. The two ends of the spring 325 are fixedly connected to the outer wall of the hinge 322 and the outer wall of the limiting sleeve 324 respectively. The spring 325 is in an extended state by default (such as Figure 8 、 Figure 12 Status shown);

[0101] The sixth gear 326 is disposed between the first set of rods 316 and the second set of rods 317;

[0102] The third motor 327 is fixedly mounted on the top of the lifting column 313 , and the output shaft of the third motor 327 is fixedly connected to the sixth gear 326 ;

[0103] A seventh gear 328 is fixedly connected to one end of the first pressing cylinder 314 , and the seventh gear 328 is meshed with the sixth gear 326 ;

[0104] The rotating seat 329 is fixedly connected to the middle portion of the first sleeve rod 316, and the output shaft of the third motor 327 is rotatably connected to the top of the rotating seat 329;

[0105] An avoidance groove 330 is provided on one side of the hinge 322. The avoidance groove 330 is used to avoid the output shaft of the third motor 327 to avoid motion interference;

[0106] like Figure 15 As shown, a long slot is formed in the middle of the lifting column 313, and a third rack 318 is provided on one inner wall of the long slot. The end of the rotating shaft 312 extends into the interior of the long slot, and the end of the rotating shaft 312 is fixedly connected to a third gear 319, which meshes with the third rack 318.

[0107] like Figure 16 、 Figure 17 As shown, in this embodiment, it also includes:

[0108] The receiving groove 331 is provided on the top of the processing table 103. The receiving groove 331 can receive the components included in the lifting assembly 300 mentioned above. When the lifting column 313 is lowered to the lowest point, the top end of the first pressing cylinder 314 is flush with the top surface of the processing table 103.

[0109] The extrusion portion 332 is provided on the inner wall of the receiving groove 331 and is located corresponding to the hinge 322. By providing the extrusion portion 332, when the lifting column 313 drops to the lowest point, the bottom of the hinge 322 and the extrusion portion 332 are squeezed against each other, thereby causing the hinge 322 to move from a tilted state (i.e. Figure 8 、 Figure 12 The sixth gear 326 is driven to rotate by the third motor 327, and the sixth gear 326 drives the seventh gear 328 to rotate, thereby rotating the first pressing cylinder 314. Due to the meshing action of the fourth gear 320 and the fifth gear 321, the first pressing cylinder 314 and the second pressing cylinder 315 rotate synchronously and oppositely, thereby conveying the plate 200 to be processed when feeding the plate 200 before it is bent.

[0110] Embodiment 2: This embodiment differs from the embodiment 1 in that it provides a plate bending device and method for processing a box-type power distribution cabinet, including the following steps:

[0111] S1. Place the plate 200 to be bent on the processing table 103 and push it slightly toward the rear of the bending machine body 101 so that the rear of the plate is clamped by the first pressing cylinder 314 and the second pressing cylinder 315.

[0112] S2. The bending portion of the plate 200 to be processed is moved to the top of the lower die 107. The upper die 106 is driven by the driving source to move downward, and is pressed against the lower die 107 to bend the plate 200 to be processed.

[0113] S3. During the bending process of the plate 200 to be processed, the driving source drives the lifting column 313 to rise synchronously with the tilted portion of the plate 200 to be processed, and the second pressing cylinder 315 rotates around the central axis of the first pressing cylinder 314, so that the second pressing cylinder 315 rotates synchronously with the tilting angle of the plate 200 to be processed;

[0114] S4. After the bending of the plate 200 to be processed is completed, the lifting column 313 descends to the lowest point, and the plate 200 to be processed is taken out, completing the bending work.

[0115] In summary, the present invention sets a lifting assembly 300 under the plate to be processed 200, so that when the plate to be processed 200 is bent, the raised portion formed can be fully supported by the lifting assembly 300, thereby ensuring that the raised portion of the plate to be processed 200 will not be deformed due to the influence of gravity, thereby ensuring the flatness of the plate to be processed 200 after bending; by lowering the lifting assembly 300 to the lowest position, the first pressing cylinder 314 and the second pressing cylinder 315 can clamp the plate to be processed 200 in a horizontal state, and then transport the plate to be processed 200 to a specified position, so that there is no need to adjust the bending position of the plate to be processed 200 separately, and it is more convenient to use; by respectively setting support columns 302 and support plates 307 at both ends of the lower mold 107, when the plate to be processed 200 is bent, the support columns 302 and the support plates 307 can respectively The support is provided for both ends of the plate 200 to be processed, thereby supporting the middle part of the plate 200 to be processed, preventing the middle part of the plate 200 to be processed from sinking under the action of gravity, and further improving the processing quality of the plate 200 to be processed; by setting the extrusion part 332, when the lifting column 313 drops to the lowest point, the bottom of the hinge 322 and the extrusion part 332 squeeze each other, thereby prompting the hinge 322 to rotate from an inclined state to a vertical state. In the vertical state, the sixth gear 326 is driven to rotate by the third motor 327, and the sixth gear 326 drives the seventh gear 328 to rotate, thereby rotating the first clamping cylinder 314. Due to the meshing action of the fourth gear 320 and the fifth gear 321, the first clamping cylinder 314 and the second clamping cylinder 315 rotate synchronously in opposite directions, thereby conveying the plate 200 to be processed when feeding before it is bent.
