Description

A kind of manufacturing and processing method of electric power high and low voltage cross arm

technical field

The invention relates to the technical field of cross arm processing, in particular to a manufacturing and processing method for electric high and low voltage cross arms.

Background technique

The cross arm is an angle iron fixed horizontally on the top of the utility pole, with a porcelain bottle on it, which is used to support the overhead wires, which is an important part of the tower. In order to maintain a certain safety distance according to the regulations, the processing steps of the cross arm include basic processes such as material selection, cutting, bending, stamping, surface finishing, assembly, etc. The length of the cross arm is determined according to the number of overhead wires and the distance between the wires. Commonly used cross-arms include angle iron cross-arms and wooden cross-arms. In some areas, low-voltage porcelain cross-arms are used. Iron cross-arms are made of angle iron, which has the advantages of durability and long service life. Ceramic cross-arms are not easy to use. It has excellent characteristics such as breakdown, not easy to age, high insulation ability, safety and reliability, etc. It is mainly used in high-voltage circuits, but the following problems will occur during the production and processing of cross arms:

1. The traditional single-station and intermittent processing has low overall work efficiency. At the same time, during the cutting and bending process of the plate, the deflection phenomenon of the plate due to the low degree of clamping and pressing is easy to cause cutting and folding. Errors and other undesirable phenomena occur at the bending point, which in turn lead to a large decline in the quality of cutting and bending;

2. It is cumbersome to use manual scribing to determine the cutting size before cutting the sheet. In the process of directly cutting the sheet, there is a large error in the size of the same batch of cutting sheets, so that the quality of the overall cross arm processing and forming has declined. At the same time, the satisfaction rate of the requirements for cutting different size and specification sheets is low.
