Embodiment 1
[0122] like figure 1 , 2-1 As shown in 2-2, a wire crimping auxiliary drawing and printing steel tape measure of the present invention comprises a ruler box, and a ruler bar rolled in the ruler box;
[0123] The ruler box is composed of a shell, a ruler, a brake, a ruler hook, a strap, an anti-fall protective cover and a label;
[0124] There are several marking points on the ruler;
[0125] The marking points include, a number of auxiliary drawing points for the tension clamp through the pipe crimping and a number of auxiliary drawing points for the connecting pipe through the pipe and crimping;
[0126] The auxiliary drawing points for connecting pipe through pipe crimping include the first binding point A 1 , the first cutting point A 2 , Steel pipe threading point A 3 、Aluminum tube Pass-through point B 1 and aluminum tube crimping starting point B 2 ;
[0127] The auxiliary drawing points of the tension clamp through tube crimping include the second binding point ...
Embodiment 2
[0190] like Figure 5-6 As shown, a method for using a wire crimping auxiliary drawing and printing steel tape measure includes the following steps:
[0191] Determine the type of wire, crimping tube, crimping machine and die;
[0192] The JL / G1A-400 / 35 steel core aluminum stranded wire produced by Jiangsu Zhongtian is used, and the crimping tube is JYD-400 / 35 straight splicing tube and NY-400 / 35 tension clamp produced by Siping Line Equipment Factory, and the crimping machine is used. And the hydraulic pump uses the YBC-III JQ hydraulic press produced by Changshu Electric Power Equipment Co., Ltd. The molds use 125TG22, L45 and C16 molds produced by Changshu Electric Power Machinery Co., Ltd. for crimping and painting;
[0193] The dimensions of the JYD-400 / 35 type straight connecting pipe and the NY-400 / 35 type tension clamp used in this example are shown in Table 1.

Abstract
The invention belongs to the technical field of wire crimping, and particularly discloses a wire crimping auxiliary drawing and printing steel tape and a use method thereof. Comprising a ruler box and a ruler strip wound in the ruler box. A plurality of identification points are arranged on the ruler strip; the plurality of identification points comprise a plurality of strain clamp tube-penetrating crimping auxiliary drawing and printing points and a plurality of splicing sleeve tube-penetrating crimping auxiliary drawing and printing points. According to the drawing and printing steel tape, the auxiliary drawing and printing identification points are arranged on the tape strip to assist in drawing and printing work, all data are measured from the starting point of the tape strip of the drawing and printing steel tape as the measuring starting point, and the problem that drawing and printing errors are caused by using unqualified measuring instruments or damaging the measuring instruments on site, and finally drawing and printing position deviation is caused is solved.
Description
technical field [0001] The invention belongs to the technical field of wire crimping, and particularly relates to a wire crimping auxiliary drawing and printing steel tape measure and a using method thereof. Background technique [0002] With the gradual improvement of UHV technology and the popularization and application of new materials, the types of conductors are gradually enriched, except for the cross-sectional area of 400mm. 2 , 630mm 2 and other common steel-cored aluminum stranded wires, there are also 1250mm 1250mm widely used in DC UHV 2 Large cross-section wires and carbon fiber composite core wires popularized in low-voltage grade lines, etc. As the key point and weak point of quality control in line construction, crimpquality control faces greater challenges. [0003] The crimping tube is the weak link in the stress-bearing structure of the overhead conductor. During the construction process, the defects such as leakage, undervoltage, and overvoltage of t...
