An electric high and low voltage cross-arm manufacturing and processing device and manufacturing and processing method

Abstract

The invention relates to a production and processing device for electric high and low voltage cross-arms, which includes a workbench, a distance adjustment device and a bending device. The middle part of the upper end surface of the workbench is equipped with distance adjustment devices at equal distances from left to right. There is a bending device directly above the device, and the lower end of the bending device is installed on the upper surface of the workbench. The invention provides an electric high and low voltage cross-arm manufacturing and processing device and a manufacturing and processing method, which adopts an adjustable multi-station The design concept of the structure bends and forms the steel plate, so that the same equipment can adapt to the needs of manufacturing and processing cross arms of different sizes, which improves the utilization rate and production efficiency of the equipment, and increases the processing benefits under the condition of a certain processing cost.

Description

technical field [0001] The invention relates to the field of electric power cross-arm processing equipment, in particular to an electric high-low voltage cross-arm manufacturing and processing device and a manufacturing and processing method. Background technique [0002] The cross arm refers to the angle iron fixed horizontally on the top of the utility pole, with a porcelain bottle on it, which is used to support the overhead wire. The commonly used cross arms include angle iron cross arms and wooden cross arms. In some areas, low-voltage porcelain cross arms are used. The use can be divided into: straight line cross arm, corner cross arm and tension cross arm. According to the voltage level, it can be divided into: high voltage cross arm and low voltage cross arm. The cross arm is an important part of the tower, and its function is to install insulators. And fittings, to support the wires and lightning conductors, and keep them at a certain safe distance according to the ...

AI Technical Summary

Problems solved by technology

[0003] (1) Usually, the cross-arm is made by bending the steel plate. The size and type of the bending die used in the bending process are fixed. The same die cannot adapt to the requirements of making cross-arms of different sizes. The use of the die The rate is low, the size of the cross-arm itself is small, but the demand is large, if the die of the corresponding size is made due to the demand for cross-arms of different sizes, it is easy to increase the processing cost. Considering the benefits of processing, it is not often used to make a large number of Method for dies of different sizes;

[0004] (2) During the bending and forming process of the steel plate by the punch, since the steel plate is simply placed on the die, the steel plate is prone to offset, resulting in changes in the bending position, and thus cannot form a cross-arm in the desired shape At the same time, the two ends of the steel plate are also prone to shrink toward the bending point, which will easily cause wrinkles on the formed cross arm, which will affect the appearance of the cross arm and reduce the use effect
