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 a box-type power distribution cabinet. Background Art

[0002] The sheet bending device is a device used to bend and fold sheets, and is widely used in metal processing, decorative panel manufacturing and other fields; 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 triggers the hydraulic component to start the conversion component in the form of hydraulic oil pressure until the bending die is pressed down by the bending tool and contacts the unloading table. The bending tool stops moving down, and the conversion component switches the oil inlet of the first oil port and the oil outlet of the second oil port to the oil outlet of the first oil port and the oil inlet of the second oil port, so that the bending tool moves up, thereby improving the processing quality of the bent workpiece; 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 fall, causing deformation of the plate. Therefore, it is necessary to improve this problem. Summary of the invention

[0003] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0004] The present invention provides a plate bending device and method for processing a box-type power distribution cabinet, which can solve the problem in the prior art that the flat part of the plate is easily deformed when the plate is bent. The specific scheme is as follows: 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 cooperates with the lower mold to bend the bending part of the plate to be processed, and also comprises a lifting component, wherein the lifting component comprises: The lifting column is slidably mounted on the top of the processing table and moves up and down driven by the driving source; The first pressing cylinder is arranged on one side of the top end of the lifting column and can rotate on its own; 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; 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 gravity, thereby ensuring the flatness of the plate to be processed after bending.

[0005] 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. A processing table is arranged below the bending machine body, and the processing table is used to carry the plate to be processed. A processing area is arranged in the middle of the bending machine body, and the processing area is located above the processing table and in the middle of the entire bending machine body, and the front and rear ends of the processing area are connected with the front and rear ends of the bending machine body.

[0006] Preferably, it also includes: A lower pressing piece, wherein the lower pressing piece is located above the processing area; A clamping tool is fixedly connected to the bottom of the lower pressing piece, and the upper mold is fixedly installed on the bottom of the clamping tool; A hydraulic rod is fixedly connected to the top of the lower pressing member, and the top end of the hydraulic rod is fixedly connected to the inside of the bending machine body. A foot pedal is also provided at one end of the bending machine body, and the foot pedal is used to control the hydraulic rod.

[0007] Preferably, it also includes: The support column is installed on one side of the lower mold and can move up and down driven by a driving source.

[0008] Preferably, it also includes: A 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 respectively 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.

[0009] Preferably, it also includes: 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; A second sleeve rod is arranged above the first sleeve rod and penetrates the interior of the second pressing cylinder, and the second sleeve rod can rotate around the first sleeve rod; A hinged member, the bottom of which is hinged 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; 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.

[0010] Preferably, it also includes: A limiting rod, fixedly connected to the outer wall of the hinge; A limiting sleeve, fixedly connected to the outer wall of the lifting column, and the limiting rod is slidably connected to the limiting sleeve; 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.

[0011] Preferably, it also includes: Sixth gear; A third motor is fixedly mounted on the top of the lifting column, and an output shaft of the third motor is fixedly connected to the sixth gear; A seventh gear, fixedly connected to one end of the first pressing cylinder, the seventh gear meshing with the sixth gear; a fourth gear, fixedly connected to an end of the first pressing cylinder; The fifth gear is fixedly connected to the end of the second pressing cylinder, and the fifth gear is meshed with the fourth gear.

[0012] Preferably, it also includes: A storage tank is provided on the top of the processing table; An extrusion portion is arranged on the inner wall of the receiving groove and its position corresponds to the hinge part; Among them, when the lifting column drops to the lowest point, the bottom of the hinge and the extrusion part squeeze each other, thereby causing 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 sheet to be processed is fed, the sheet 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 sheet to be processed in a horizontal state, and then convey the sheet to be processed to a specified position, so that there is no need to adjust the bending position of the sheet to be processed separately, which is more convenient to use.

[0013] A plate bending method for processing a box-type power distribution cabinet comprises the following steps: 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 clamping cylinder and the second clamping cylinder; S2, the bending part of the plate to be processed is moved to the top of the lower die, and the upper die is driven by the driving source to move downward, and is pressed against the lower die to bend the plate to be processed; S3. During the bending process of the plate to be processed, the driving source drives the lifting column and the raised part 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 and the raised angle of the plate to be processed rotate synchronously; S4. After the bending of the plate to be processed is completed, the lifting column descends to the lowest point, the plate to be processed is taken out, and the bending work is completed.

[0014] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: 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.

[0015] 2. 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 transport the plate to be processed to a 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.

[0016] 3. By respectively 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 the two 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.

[0017] 4. By setting the 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 allowing the first clamping cylinder to rotate. 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.

[0018] 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.

A hydraulic rod 108 is fixedly connected to the top of the lower pressure piece 104. The top end 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 arranged at one end of the bending machine body 101. The foot button is used to control the hydraulic rod 108.

[0023] like Figure 5 , Figure 6 As shown, in this embodiment, in order to prevent the flat part of the plate 200 to be processed from rotating with the bent part as a fulcrum under the action of gravity after the plate 200 to be processed is bent, resulting in deformation of the flat part of the plate 200 to be processed, a lifting assembly 300 is further provided on the processing table 103, and the lifting assembly 300 is used to support the plate 200 to be processed after being bent; like Figure 7 , Figure 8 As 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.

A support column 302 is arranged on the top of the first rack 301. A receiving groove matching the support column 302 is opened on the top of the processing table 103. The receiving groove can completely wrap the support column 302, so that 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.

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, so that the support column 302 on the top of the first rack 301 can support the bottom of the plate 200 to be processed, thereby providing a supporting force for the plate 200 to be processed. The support plate 307 is installed on the other side of the lower mold 107 to provide support for the other end of the plate 200 to be processed.

The extrusion part 332 is arranged on the inner wall of the receiving groove 331, and the position corresponds to the hinge 322. 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 are pressed against each other, thereby causing the hinge 322 to move from the inclined state (that is, Figure 8 , Fig.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 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 and oppositely, thereby conveying the sheet material 200 to be processed when feeding before the sheet material 200 to be processed is bent.

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 and oppositely, thereby conveying the plate 200 to be processed when feeding before the plate 200 to be processed is bent.
