Description

Technical Field

[0001] The invention relates to the technical field of cable tray cutting, in particular to a cable tray cutting platform. Background Art

[0002] In the field of cable tray manufacturing and processing, cable trays, as a critical infrastructure component, primarily support and secure cables, ensuring the stability and safety of cable systems. Their quality and precision are crucial to the safety and stability of cable systems. Cable trays typically utilize a U-shaped design, which not only facilitates cable routing and securing but also provides structural strength and stability.

[0003] Traditional cable tray cutting equipment typically uses mechanical shearing or sawing methods, which have certain structural limitations. Specifically, when the equipment begins operation, the cutter first directly contacts the two edges of the cable tray, applying a vertical downward cutting force.

[0004] In cable tray installation projects, in order to ensure the smoothness and aesthetics of cable layout, curved cable trays are often required to adapt to the special direction of the building structure. This type of curved cable tray is usually formed by cold bending or hot bending. The bending parts have generated obvious internal residual stress during the forming process. During actual cutting operations, the traditional clamping method often uses large-area clamping plates for fixation. This fixing method will bring a series of problems. Due to the special geometric shape of the curved cable tray, the clamping plate with a large clamping surface will produce uneven local pressure on its side wall. This pressure will produce a complex interaction with the original residual stress of the cable tray. When the clamping force is released after the cutting is completed, the cable tray will undergo secondary deformation due to the combined effect of elastic recovery and residual stress, causing the cut cable tray to bend or twist as a whole, and its arc radius deviates from the design requirements, and the end face flatness is reduced. Summary of the Invention

[0005] Based on the above-mentioned problems existing in the prior art, the problem to be solved by this application is: in order to ensure the effective arrangement of cables during the specific operation process, an arc-shaped cable tray will be used for installation. When the arc-shaped cable tray is cut, both ends of the bend need to be fixed. However, during the cutting process, due to the stress of the arc-shaped cable tray itself, the clamping plate with a large clamping surface will locally press on the side wall of the arc-shaped cable tray. After the plate is released after cutting, the residual stress will cause the entire plate to bend and deform, affecting the subsequent use of the cable tray.
