Device for manufacturing and machining electric power high-low voltage cross arms and manufacturing and machining method thereof

Abstract

The invention relates to a device for manufacturing and machining electric power high-low voltage cross arms. The device comprises a workbench, distance adjusting devices and bending devices, whereinthe distance adjusting devices are sequentially and equidistantly installed in the middle of the upper end face of the workbench from left to right, each bending device is arranged over the corresponding distance adjusting device, and the lower ends of the bending devices are installed on the upper end face of the workbench. According to the device for manufacturing and machining the electric power high-low voltage cross arms and a manufacturing and machining method thereof provided by the invention, a steel plate is bent and formed by adopting a design concept of an adjustable multi-station structure, so that the same device meets the requirements of manufacturing and machining the cross arms with different sizes, the utilization rate and the manufacturing efficiency of the device are improved, and the machining benefit is increased under the condition of certain machining 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 steel plate is bent and other treatments are used to make the cross arm. 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, because 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
