Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0020] Referring to the accompanying drawings, a plug-in wire rope joint includes a casting body 4 and a steel wire rope 7. The ends of the steel wire rope 7 are inserted into the opening of the casting body 4 and welded together. The casting body 4 is a closed type with an open end. Casting body, the inner cavity of the opening end of the pouring body 4 is divided into an inverted cone cavity 4-2 and a feeding cavity 4-1, the inverted cone cavity 4-2 is a tapered mouth that gradually shrinks from the inside to the outside, and the feeding cavity The shrinking chamber 4-1 is arranged at the outer end of the inverted cone chamber 4-2, and the inner diameter of the feeding chamber 4-1 at the transition between the feeding chamber 4-1 and the inverted cone chamber 4-2 is larger than that of the inverted cone chamber 4-2 The inner diameter of the ...

Abstract

The invention relates to a plug-in steel wire rope connector which comprises a casting body and a steel wire rope. The end of the steel wire rope is inserted into an opening of the casting body and welded together. The casting body is a closed type casting body with an opening formed in the end. An inner cavity of the opening end of the casting body is divided into an inverted-cone cavity body and a filling shrinkage cavity body. The inverted-cone cavity body is a cone opening gradually shrunk from inside to outside. The filling shrinkage cavity body is formed in the outer end of the inverted-cone cavity body. The inner diameter of the filling shrinkage cavity body is larger than the inner diameter of the inverted-cone cavity body at the transition portion of the filling shrinkage cavity body and the inverted-cone cavity body. According to the plug-in steel wire rope connector, as the casting body is arranged in a closed form with one end open, the filling shrinkage cavity body is designed in the end, before the end of the steel wire rope is inserted into the casting body, brazing filler metal is placed into the casting body, and the brazing filler metal in the filling shrinkage cavity body is shrunk due to the fact that liquid brazing filler metal in the inverted-cone cavity body is cooled and turned into a solid, so that most brazing filler metal flows into the inverted-cone cavity body, and a welding seam structure basically flawless in the inverted-cone cavity body is formed.

Description

technical field [0001] The invention relates to a plug-in steel cable joint and a manufacturing method thereof. Background technique [0002] At present, pouring type wire rope joints all adopt pouring type wire rope joints, that is, the pouring body of the cable joint adopts a through-hole structure. When pouring, coat the cleaned steel wire rope with flux and put it into the pouring body, seal the position where the end of the pouring body contacts the steel wire rope with sealing mud, and wrap the steel wire rope with asbestos paper to prevent the steel wire rope from overheating during the pouring process and reduce its strength. The flame spray gun is used to preheat the outside of the casting body, and then the liquid brazing material at a certain temperature is poured into the casting body from the other end of the casting body to form a metallurgical joint between the steel wire rope, the casting body and the solder respectively. After the brazing filler metal is so...
