Description

Technical Field

[0001] This invention belongs to the field of cable tray technology, specifically relating to a punching and bending device for cable tray processing and its usage method. Background Technology

[0002] Cable trays are classified into trough type, tray type, ladder type, and mesh type structures. They consist of supports, brackets, and installation accessories. Cable trays inside buildings can be installed independently or laid on various building and pipe rack supports. They should be characterized by simple structure, beautiful appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. Cable trays installed outdoors are also available.

[0003] The cable tray manufacturing process requires the use of bending equipment to bend the cable trays to the required bending angle. Existing bending devices have the following problems when in use:

[0004] 1. When the punching and bending device punches and bends the cable tray, the aluminum alloy plate may shift due to the punching and bending angle, resulting in changes in the punching and bending angle and width, and errors in the processing dimensions of the cable tray;

[0005] 2. During the processing of the punching and bending device, the aluminum alloy plate to be processed needs to be conveyed. However, in the existing aluminum alloy plate conveying process, due to the lack of a limiting structure, the conveying of the aluminum alloy plate is deviated and cannot accurately reach the processing position, which affects the punching and bending processing of cable trays. Therefore, we propose a punching and bending device for cable tray processing and its usage method. Summary of the Invention

[0031] A method for using a punching and bending device for processing cable trays includes the following steps:

[0032] S1: When in use, first place the aluminum alloy plate produced in the previous process on the conveying mechanism. At this time, the aluminum alloy plate is between the lower conveying wheel and the upper conveying wheel. Then the conveying motor starts to rotate. At this time, the conveying motor drives the fixed shaft to rotate, which in turn drives the upper conveying wheel to rotate. Then the aluminum alloy plate is conveyed to the stamping mechanism under the pressing and rotating of the lower conveying wheel and the upper conveying wheel.

Then the first stamping component is started. At this time, the first stamping hydraulic cylinder pushes the first stamping plate downward. The first stamping plate punches and bends the rear part of the aluminum alloy sheet through the stamping table. Then the first stamping component and the first positioning and fixing component return to the initial state.

[0035] S4: Then the aluminum panel is pushed to the right by the next aluminum panel. At this time, the aluminum panel is transported to the right half of the stamping table. Then the second positioning and fixing components and the third positioning and fixing components are started simultaneously. At this time, the second clamping hydraulic cylinder pushes the second pressing plate downward until the second pressing plate presses and fixes the aluminum panel. At the same time, the third clamping hydraulic cylinder moves the third pressing plate to the rear side of the bent aluminum panel until the third pressing plate presses and fixes the rear side plate of the bent aluminum panel.

[0036] S5: Then the second stamping assembly is started. At this time, the second stamping hydraulic cylinder pushes the second stamping plate downward. The second stamping plate presses and bends the front side plate of the aluminum alloy plate through the stamping table. At this time, the aluminum alloy plate is pressed and bent into a U-shaped structure, and the stamping is completed.

[0037] Compared with the prior art, the beneficial effects of the present invention are:

[0038] 1. The present invention is equipped with a positioning and fixing mechanism, which can fix and clamp the aluminum alloy plate during the bending process, prevent the aluminum alloy plate from shifting position, effectively solve the problem of position shift during the punching and bending process of cable trays, and improve the dimensional accuracy of the processing.

[0039] 2. The present invention is equipped with a guide and limiting component. During the conveying process of the aluminum alloy plate, both the front and rear sides of the aluminum alloy plate are in contact with the guide and limiting component and conveyed to the right.

Then the first stamping component and the first positioning and fixing component return to the initial state. S4: Then the aluminum panel is pushed to the right by the next aluminum panel. At this time, the aluminum panel is transported to the right half of the stamping table. Then the second positioning and fixing components and the third positioning and fixing components are started simultaneously. At this time, the second clamping hydraulic cylinder pushes the second pressing plate downward until the second pressing plate presses and fixes the aluminum panel. At the same time, the third clamping hydraulic cylinder moves the third pressing plate to the rear side of the bent aluminum panel until the third pressing plate presses and fixes the rear side plate of the bent aluminum panel. S5: Then the second stamping assembly is started. At this time, the second stamping hydraulic cylinder pushes the second stamping plate downward. The second stamping plate presses and bends the front side plate of the aluminum alloy plate through the stamping table. At this time, the aluminum alloy plate is pressed and bent into a U-shaped structure, and the stamping is completed.

2. The method of using the punching and bending device for cable tray processing according to claim 1, characterized in that: The conveying mechanism includes a lower conveying component and an upper conveying component that cooperates with the lower conveying component; The lower conveying assembly includes a conveying support platform disposed on the processing table and a lower conveying wheel rotatably disposed on the conveying support platform; The upper conveying assembly includes an upper conveying wheel that is vertically aligned with the lower conveying wheel and a fixed shaft that is rotatably mounted on the processing table and connected to the upper conveying wheel. A conveying motor connected to the fixed shaft is installed on the rear side of the processing table. The lower conveyor wheel and the upper conveyor wheel press against each other and rotate to convey the aluminum alloy plate disposed between the lower conveyor wheel and the upper conveyor wheel to the stamping mechanism.

3. The method of using the punching and bending device for cable tray processing according to claim 2, characterized in that: A conveyor wheel groove is provided on the conveyor platform at the position corresponding to the lower conveyor wheel, and the lower conveyor wheel is rotatably mounted in the conveyor wheel groove via a rotating shaft; A support plate is provided on the front side of the processing table at the position corresponding to the fixed shaft. A rotating seat is provided on the processing table and the support plate at the position corresponding to the fixed shaft. The output end of the conveying motor passes through the rotating seat and is connected to the fixed shaft.

4. The method of using the punching and bending device for cable tray processing according to claim 1, characterized in that: The guide and limiting assembly includes a support base installed on the processing table, a fixed round rod disposed on the support base, and a rotating cylinder sleeved on the fixed round rod; The rotating drum is rotatably mounted on the fixed round rod. The rotating drum is used to guide and limit the front and rear sides of the aluminum alloy plate so that the aluminum alloy plate can move along a specified direction.
