Cable tray production methods and processes
Cable tray is to make the wire, cable, pipeline laying standardization, serialization, universal cable laying device. mainly applicable10 kVThe laying of the following power cables, control cables, lighting distribution and other indoor and outdoor overhead cable trenches and tunnels. Cable tray can be erected independently, can also be attached to a variety of buildings and pipe rack.
Cable tray is generally straight groove type structure, corner is generally used on-site processing straight bridge production. Next, an arc bridge with simple process and stable bridge quality and its manufacturing method are introduced. The arc-shaped cable bridge includes an arc-shaped bottom plate; two arc-shaped upper plates, respectively located on opposite sides of the arc-shaped bottom plate, extending along the side of the arc-shaped bottom plate, and connected with the arc-shaped bottom plate; the edges of the two arc-shaped upper plates are respectively arranged along the side of the arc-shaped upper plate and extend in opposite directions; the shape of the arc-shaped upper plate matches the shape of the arc-shaped bottom plate.
The manufacturing method of the curved cable tray includes the following steps: determining the outer arc length and the inner arc length of the curved cable tray; providing a plate, and cutting the plate according to the outer arc length and the inner arc length; plasma cutting the cut plate to obtain the arc bottom plate, the semi-finished arc upper plate and the edge of the arc upper plate; stamping the semi-finished arc upper plate to obtain the arc upper plate; welding the edge of the arc upper plate to the arc upper plate, obtain the formed arc-shaped upper plate, the shape of the arc-shaped upper plate matches the shape of the arc-shaped bottom plate; weld the formed arc-shaped upper plate on both sides of the arc-shaped bottom plate to obtain the arc-shaped bridge; the semi-finished arc-shaped upper plate The plate is stamped to obtain the arc-shaped upper plate; after the steps of welding the formed arc-shaped upper plate to both sides of the arc-shaped bottom plate to obtain the arc bridge frame; before the step of plasma cutting the cutting board to obtain the arc-shaped bottom plate, the semi-finished arc-shaped upper plate and the edge of the arc-shaped upper plate, it also includes: drawing the specifications and dimensions required for cutting in the computer, editing the program according to the size of the board, and then editing Send to the plasma cutting machine, and then adjust the parameters, power, bandwidth, speed and cutting nozzle height of the plasma cutting machine. The manufacturing method of the above-mentioned arc cable bridge is based on the outer arc length and inner arc length of the arc cable bridge, so that the arc cable bridge can be manufactured and installed according to the direction of the ceiling curve of the building, and the arc cable bridge is directly processed in the factory according to the parameters, which reduces the labor time and improves the work efficiency of the operator. In addition, the manufacturing method of the curve cable bridge is simple, and the quality of the curve cable bridge is stable. It can also be installed parallel to the arc building or according to the curve of the ceiling. The operation is simple and the work efficiency of the operator is improved.
After the step of obtaining the curve bridge, the curve bridge should be inspected to remove burrs and welding slag, and polish uneven welding cracks. In addition, check whether the curved bridge cover plate is consistent with the curved bridge, and transport it to the construction site after passing the inspection. Curve bridge in the actual should be applied to the shopping center of the above curve cable tray. It can be seen that the curved bridge is parallel to the curved building, and can be arranged along the curve of the ceiling, which is neatly arranged, which improves the space utilization of the mall.
