Embodiment Construction

[0042] A processing technology for a double-ear wedge-shaped clamp shell for electrified railways, the specific steps are as follows:

[0043] 1) if Picture 1-1 , 1-2 As shown in and 1-3, the heated raw material is pre-forged, and the pre-forged forging billet has two ears and a solid part connecting the roots of the two ears. The distance between the parts is gradually increased, and the molds used include matching punches and dies, see Figure 8 and Figure 9 On the left side of the punch, the forging face of the punch gradually protrudes from both ends to the middle in the length direction and transitions smoothly in the middle. The die cavity of the die matches the punch. In the length direction, the middle part of the die cavity also has A concave third pit;

[0044] 2) if diagram 2-1 , 2-2 As shown in 2-3, the second forging is carried out, and the two ears are forged to be on the same plane. The forging billet formed by the second forging is in the shape of ┯ as...

Abstract

The invention provides a processing technology for a double-lug wedge wire clamp housing for an electric railway. The specific steps comprises S1, pre-forging heated raw material, wherein a pre-forged blank has two lug portions and a solid body, and the whole blank is Y-shaped; S2, secondary forging, forging the two lug portions in the same plane, wherein the whole secondary forged blank is T-shaped, and the solid body has an inner hole; S3, fine forging, wherein the whole fine forged blank is T-shaped, and the inner hole is deepened to meet the side of an inner hole of a, finished double-lug wedge wire clamp housing; S4, processing the two lug portions in the same plane into two opposite lug portions just like two opposite lug portions of the finished double-lug wedge wire clamp housing, S5, cutting the bottom of the solid body to make the inner hole into a through hole, forging the bottom of the solid body to make the bottom like a finished double-lug wedge wire clamp housing, and punching the two lug portions to make pin through holes.

Description

technical field [0001] The invention relates to an electrified railway catenary component, in particular to a processing technology for a double-ear wedge-shaped clamp shell for an electrified railway. Background technique [0002] The double-ear wedge-shaped clamp is suitable for the connection between the terminal and the ear-shaped parts of the electrified railway catenary system, which uses metal stranded wire as the load-bearing cable, horizontal load-bearing cable, upper and lower positioning ropes and compensation ropes. The double-ear wedge-shaped clamp shell is manufactured by paraffin investment casting process, which has the defect of low mechanical properties. Figure 7-1 and Figure 7-2 A double ear wedge clamp is shown, comprising a housing 1 , a wedge 2 and a pin 3 . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a processing technology for a double-ear wedge-shaped clamp shell for electrified ra...
