ACSR crimping device

Abstract

A steel-cored aluminum stranded wire crimping device, including a frame, a first steel-cored aluminum stranded wire clamping mechanism on the upper part of the left end, and a second steel-cored aluminum stranded wire clamping mechanism on the upper part of the right end; a mobile platform is arranged on the upper part of the frame ; The driving mechanism of the mobile platform is set on the first or second ACSR clamping mechanism and is connected with the mobile platform; a pair of crimping die opening cylinders are set on the mobile platform; the lifting mechanism of the pressing plate is fixed on the It is on the mobile platform and corresponds to the top of a pair of crimping die opening and closing cylinders; the mold changing moving plate is set on the moving platform; the driving mechanism of the mold changing moving plate is set on the moving platform and connected with the mold changing moving plate; The steel core stranded wire sleeve extrusion die is supported on the left end of the mold changing movable plate, and a pair of aluminum stranded wire sleeve extrusion dies is supported on the right end of the mold changing movable plate. Reduce the amount of equipment used; the structure is concise, easy to manufacture and use; it reflects a good secondary crimping effect, ensuring the quality of the connection of the transmission line; ensuring the tensile strength of the steel core stranded wire at the connection.

Description

technical field [0001] The invention belongs to the technical field of power transmission line crimping tools, and in particular relates to a steel core aluminum stranded wire crimping device. Background technique [0002] From the terminology of the above-mentioned aluminum-steel-reinforced wire, it can be determined without a doubt that the center of the wire is the steel strand, and the outside of the wire is the aluminum strand that is enveloped outside the steel strand. Because the steel strand has high mechanical strength and strong tensile force, the steel strand is not suitable for power transmission, and because the mechanical strength and tensile force of the aluminum strand are not comparable to the steel strand, but the aluminum strand has The excellent electrical conductivity (small resistivity) and small specific gravity that steel strands cannot have, so the aforementioned steel-cored aluminum strands are widely used in high-power, high-power Voltage, long-di...

Problems solved by technology

Since these patents, not limited to examples, also only use a single crimp, it is not sufficient to eliminate the aforementioned technical problems

[0007] Undoubtedly, the steel cores of the two steel-cored aluminum stranded wires, that is, the head and tail parts of the steel stranded core and the head and tail parts of the aluminum stranded wires, can be completely eliminated by the same device. There is no corresponding report in the patent and non-patent literature, and the technical solution to be introduced below is produced under this background
