Crimp structure of aluminum steel cored wire

Abstract

This patent discloses a crimping structure of a steel core aluminum strand, including the rack, Conductor placement table, aluminium tube placement table, Wire feed unit and hydraulic unit, Conductorplacement table, An aluminum tube placing table and a wire feeding unit are sequentially fixed on the rack from left to right, A lead feed unit include a side plate, Support plate, first motor, A T-shape plate and a drive mechanism, the side panels are secured to the frame, A support plate is slidably connected to that side plate, the T-shaped plate is fixedly connected with the output shaft of the first motor, The upper part of the T-shaped plate is provided with a through groove through which the steel core aluminum strand can pass, and the driving mechanism can push the support plate to move to the left. The hydraulic unit comprises a top plate, an air cylinder and a hydraulic press, wherein the top plate is fixed on the frame, the air cylinder is fixed on the top plate, the hydraulic press is fixedly connected with the output shaft of the air cylinder, and the hydraulic unit is positioned directly above the aluminum pipe placing table. The invention can complete the crimping step by using the mechanical movement, and solves the problem that the steel core aluminum strand is easy to slide out of the aluminum pipe after being crimped.

Description

technical field [0001] The invention relates to the technical field of crimping structures for power transmission lines, in particular to a crimping structure for steel-cored aluminum stranded wires. Background technique [0002] Hydraulic crimping operation is a common type of work in power systems. According to the process standard of "DLT5285-2013 Hydraulic Crimping Process Regulations for Overhead Conductors and Ground Wires of Power Transmission and Transformation Engineering", there are mainly five steps as follows: ①Drawing and printing (i.e. measuring line The depth of the clamped aluminum tube is marked on the wire); ② Alignment through the tube (the marked wire is about to pass into the aluminum tube); ③ Place it on the crimping machine; ④ Crimp (that is, start the crimping machine, Crimp it according to the pressure standard); ⑤ Secondary treatment after crimping (that is, secondary treatment for burrs, flashes, bending, etc. after crimping). [0003] At present,...
