Solid die forging crescent type suspending wire clip and manufacturing process for wire clip body

Abstract

The invention provides a solid die forging crescent shaped suspension wiring clip, which comprises a wiring clip body with a U-shaped cross section, a U-shaped hanging plate, a connecting bolt, a U-shaped bolt, a tension disc and a pin. The edge position of the wiring clip body adopts a large curvature lip and smooth arc transition to increase a charge concentrated area at a wiring outlet, so that corona discharge phenomenon which easily happens previously can be greatly reduced, and the wiring clip has excellent corona discharge resistance. A wiring clip shell adopts a crescent shape to ensure that stress concentration of the original cable and the wiring clip body due to gravitational factor can be eliminated or reduced. The edge of the U-shaped hanging plate is in smooth arc transition, so that the corona discharge phenomenon which easily happens previously can be greatly reduced. The center point of the pin is higher than a quality center point of the wiring clip body, so that the wiring clip body can swing flexibly to absorb vibrational energy transferred from a lead wire. By adopting the solid die forging process, destroy load of the wiring clip is greatly improved. The invention has the advantages of smart design, good use effect and high strength, improves security and reliability of power high-tension transmission line, and can meet the requirement of line operation.

Description

technical field [0001] The invention relates to a solid-state die-forging crescent-shaped suspension clamp for high-voltage transmission lines and the clamp housing is manufactured by a solid-state die-forging process. Background technique [0002] At present, the suspension clamps and clamp housings actually used in high-voltage transmission lines are manufactured by aluminum alloy liquid casting process. [0003] The disadvantage of this aluminum alloy liquid casting suspension clamp housing is that the volume of the clamp housing must be increased in order to achieve good anti-corona effect and high-strength failure load, which results in a substantial increase in material consumption. This is due to the loose metallographic structure and low strength of the liquid casting process. Also have the hanging point pin hole of this kind of wire clip to be positioned at the mass center of the whole wire clip main body, cause the wire clip main body to swing inflexibly, and it i...

[0003] The disadvantage of the suspension clamp shell of this aluminum alloy liquid casting is: to achieve a good anti-corona effect and high-strength damage load, the volume of the clamp shell must be increased, which results in a substantial increase in the amount of materials used

In addition, the lifting point pin hole of this kind of clamp is located at the mass center of the entire clamp main body, causing the main body of the clamp to swing inflexibly, and it is difficult to absorb the energy transmitted by the wire.
