Description

Technical Field

[0001] This utility model relates to the field of cable tray manufacturing technology, specifically a high-efficiency aluminum alloy cable tray bending device. Background Technology

[0002] Aluminum alloy cable trays are characterized by their attractive appearance, simple structure, unique design, high load-bearing capacity, and light weight. After anodizing, aluminum alloy cable trays not only resist corrosion but also electromagnetic interference, especially shielding interference—qualities that steel cable trays cannot match. Aluminum alloy cable trays hold significant practical value in modern industry and high technology.

[0003] The existing aluminum alloy cable trays are bent on one side by a bending machine and then moved to bend the other side. This method is inefficient, impractical, and takes too much time when dealing with a large number of bending operations.

[0004] Therefore, it is necessary to design a highly efficient aluminum alloy cable tray bending device that is practical and allows for rapid bending. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency aluminum alloy cable tray bending device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency aluminum alloy cable tray bending device, comprising a base, a support frame above the base, a first cylinder above the support frame, a lower pressure plate fixedly installed at the rod end of the first cylinder, a presser slidably connected inside the lower pressure plate, a spring welded above the presser, the spring being welded to the lower pressure plate above, a buffer above the support frame, and a fixing plate at the bottom of the presser.

[0007] According to the above technical solution, a support plate is provided above the base, a rotator is provided on the rear side of the support plate, and a bending plate is provided at the rotating end of the rotator.

[0008] According to the above technical solution, a connecting rod is provided on the outer side of the bending plate, a universal head is provided above the connecting rod, a pull rope is provided on the outer side of the universal head, and a rope take-up device is provided on the outer side of the lower pressure plate. The take-up device and the pull rope are connected to each other.

[0009] According to the above technical solution, a telescopic device is provided at the bottom of the pallet, a telescopic rod is slidably connected inside the telescopic device, a transition plate is provided at the rear end of the telescopic rod, a second cylinder is provided on the rear side of the transition plate, and a push plate is provided at the rod end of the second cylinder.

[0010] According to the above technical solution, a conveyor plate is provided on the rear side of the pallet, and a first conveyor belt is provided on the right side of the base.

[0011] According to the above technical solution, a second conveyor belt is provided on the front side of the pallet.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0013] (1) By setting up a bending plate, the aluminum alloy plate is fixed on the support plate. After the center part is fixed, the rotator starts to drive the bending plate to bend inward, thereby driving the two ends of the aluminum alloy plate to bend inward, achieving the bending effect. When bending, the rope take-up device starts to retract the rope at the same time, thereby assisting to drive the bending plate to retract inward, improving the bending efficiency, and ensuring that the bending angle meets the requirements.

[0014] (2) By setting up a telescopic device, the telescopic device can drive the telescopic rod to extend and retract inside, thereby driving the second cylinder to move through the adapter plate, and pushing the aluminum alloy plate into the designated position of the pallet through the push plate. After the bending is completed, the second cylinder starts to extend the air rod, driving the push plate to continue to move inward, thereby pushing the aluminum alloy plate away from the pallet.

[0015] (3) With the lower pressure plate set, after the aluminum alloy plate reaches the designated position, the first cylinder starts and drives the air rod to descend, thereby driving the lower pressure plate to move downward. Then the fixing plate will touch the aluminum alloy plate, and then the lower pressure plate will continue to move downward for a distance. At this time, the spring will be compressed by force, and the presser will contract inward in the lower pressure plate to achieve the fixing effect while preventing the lower pressure distance from being too far, which could damage the first cylinder or the base.

After the aluminum alloy plate reaches the designated position, the first cylinder 3 is activated to drive the rod down, thereby driving the lower pressure plate 4 to move downward. Then the fixing plate 7 will touch the aluminum alloy plate, and then the lower pressure plate 4 will continue to move downward a certain distance. At this time, the spring 5 will be compressed under force, and the presser 6 will contract inward inside the lower pressure plate 4, achieving a fixing effect while preventing excessive downward pressure distance from damaging the first cylinder 3 or the base 1.

[0022] A support plate 8 is provided above the base 1, and a rotator 9 is provided on the rear side of the support plate 8. A bending plate 10 is provided at the rotating end of the rotator 9. After the aluminum alloy plate is fixed on the support plate 8 and the center part is fixed, the rotator 9 is started to drive the bending plate 10 to bend inward, thereby driving both ends of the aluminum alloy plate to bend inward, achieving the bending effect.

The take-up end of the rope take-up device 14 is connected to the pull rope 13. When bending, the rope take-up device 14 simultaneously starts to retract the pull rope 13, thereby assisting in driving the bending plate 10 to retract inward, improving bending efficiency, and ensuring that the bending angle meets the requirements.

The push plate 19 pushes the aluminum alloy plate into the designated position of the pallet 8. After the bending is completed, the second cylinder 18 starts to extend the air rod, driving the push plate 19 to continue to move inward, thereby pushing the aluminum alloy plate away from the pallet 8.

[0025] A conveyor plate 20 is provided on the rear side of the pallet 8, and a first conveyor belt 21 is provided on the right side of the base 1. The worker places the aluminum alloy plate on the first conveyor belt 21, which will then convey the aluminum alloy plate to the conveyor plate 20, and wait for the telescopic device 15 to drive the push plate 19 to push it into the pallet 8.

[0026] A second conveyor belt 22 is provided on the front side of the pallet 8. The second cylinder 18 drives the push plate 19 to move backward away from the pallet 8 and then completely leave the pallet 8 through the second conveyor belt 22, thus completing the bending.
