Problems solved by technology

[0003] At present, for the processing of terminal balls, mold-type processing is generally used, that is, to manufacture a mold with the same size as the terminal ball for pouring-cooling-placement-forming. Using this method, the wall of the processed terminal ball is relatively thick, and The surface is not smooth, which greatly reduces the performance of the terminal ball itself, and the surface often has cracks, wrinkles, inclusions, deformation and distortion

Abstract

The invention belongs to the field of terminal ball machining, and relates to a machining method for a terminal ball. Firstly, terminal ball pouring liquid is evenly poured in a terminal ball die shell perpendicular to the ground; then, the terminal ball die shell does speed changing rotation along the transverse central axis of the terminal ball die shell; meanwhile, the terminal ball die shell does the mean-speed angular rotation along the longitudinal central axis of the terminal ball die shell; and finally, when the terminal ball die shell rotates to be parallel to the ground along the longitudinal central axis of the terminal ball die shell, in other words, after a whole inner cavity of the terminal ball die shell is full of the terminal ball pouring liquid, the needed terminal ball can be obtained through normal-temperature placing and cooling. By means of the provided machining method, the machining time can be greatly shortened, the ball wall of the machined terminal ball is thinner, the surface of the generatrix of the terminal ball is smooth and flat, and the phenomena of cracks, wrinkling, inclusions, deformation and twisting are avoided.

Description

technical field [0001] The invention belongs to the field of terminal ball processing and relates to a terminal ball processing method. Background technique [0002] The terminal ball is mainly used in the conductor connection between the power grid transmission wire and the substation transformer, the jumper wire in the transmission line, the connecting conductor in the power equipment and the overcurrent conductor in the high current DC ice melting device in the electric power construction project of our country. The new conductors of the traditional rectangular, slotted, rod-shaped busbars and flexible wires are one of the key equipment (materials) in the power transmission and transformation system, and play a vital role in the safe and reliable operation of the power transmission and transformation system and power equipment. important role. [0003] At present, for the processing of terminal balls, mold-type processing is generally adopted, that is, a mold with the sa...
