Method for manufacturing and processing electric high-low-volage cross arm

Abstract

The invention relates to a method for manufacturing and processing an electric high-low-volage cross arm. The method for manufacturing and processing electric high-low-volage cross arm is used, and comprises a cut-off mechanism and ending mechanisms. The lower end of the cut-off mechanism is mounted on the existing work ground, and bending mechanisms are arranged on the right side of the cut-off mechanism in a front-back symmetry manner. The included angle between the bending mechanisms and the cut-off mechanism is 45 degrees. The lower ends of the bending mechanisms are mounted on the existing work ground. According to the device, the design concept of a multi-station continuous structure is adopted for manufacturing and processing the electric high-low-volage cross arm, the arranged cut-off mechanism, conversion set and bending mechanism can cooperate to achieve automatic continuous double-station plate processing and forming, and then the overall work efficiency is improved; and meanwhile structures with pressing functions are arranged for a cut-off step and a bending step correspondingly to improve the forming quality of the cross arm.

Description

technical field [0001] The invention relates to the technical field of cross-arm processing, in particular to a method for manufacturing and processing electric high-low voltage cross-arms. Background technique [0002] The cross arm is the angle iron fixed horizontally on the top of the utility pole. There is a porcelain bottle on it to support the overhead wire. It is an important part of the pole tower. Keep 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, and assembly. 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. Excellen...

AI Technical Summary

Problems solved by technology

[0003] 1. The overall work efficiency of the traditional single-station and intermittent processing and forming processing is low. 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 bending. Errors and other undesirable phenomena at the bending point, which in turn lead to a large drop in the quality of cutting and bending;

[0004] 2. It is cumbersome to use manual marking to determine the cutting size before cutting the board. In the process of directly cutting the board, there is a large error in the size of the same batch of cutting boards, so that the quality of the overall cross-arm processing and forming has declined. , and at the same time, the satisfaction rate of the requirements for cutting plates of different sizes and specifications is low
