Abstract

The invention discloses a traction joint which is characterized in that the traction joint is a steel integrated piece and comprises a main body part and connecting parts located on the left side and the right side of the main body part. The main body part is of a cylinder shape with an axis arranged along the left direction and the right direction, the diameter of the main body part is 1-1.2 mm less than the diameter of a cable to be extruded out. Water stopping grooves are formed in the main body part, the number of the water stopping grooves is 2-8. The water stopping grooves are sequentially arranged at same intervals from the left to the right along the axial direction of the main body part. The connecting parts are divided into a left connecting part and a right connecting part according to the different positions of left and right. The left connecting part and the right connecting part are corresponding in shape and structure, and symmetrically arranged on the left side and the right side of the main body part. A left cable hole is formed between the left connecting part and the main body part, and a right cable hole is formed between the right connecting part and the main body part.

Description

[0001] The present invention is a divisional application of the invention patent application with the application number 201210590685.0, the application date is December 29, 2012, and the invention name is "traction joint". technical field

[0002] The invention relates to the field of cable processing and production, in particular to a method for preventing steam from entering a rubber-sheathed cable when a traction joint is used to connect a traction line and an extrusion line. Background technique

[0003] Compared with plastic-coated cables, rubber-sheathed cables (rubber-coated cables) have many advantages: good flexibility, oil resistance, torsion resistance, wear resistance, etc. During the production of rubber-coated cables, the conductor is extruded and covered with a rubber sleeve through the mold core, and then the rubber is vulcanized through a pipeline filled with high-pressure steam. The existing vulcanization equipment is in the water-vapor balance mode, so tha...

Examples

Embodiment 1）

[0032] See Figure 1 to Figure 4, the traction joint 100 of the present invention is a steel integral piece, including a main body 1 and connecting parts 2 located on the left and right sides of the main body 1 . The main body 1 is in the shape of a cylinder whose axis is arranged along the left and right directions. The diameter of the main body 1 is 1 to 12 mm smaller than the diameter of the wire to be extruded. When the wire diameter of the outgoing line is 12 to 15 mm, the diameter of the main body 1 is 1 to 2 mm smaller than the wire diameter of the wire to be extruded; when the wire diameter of the wire to be extruded is 15 to 20 mm, the diameter of the main body 1 1 to 3 millimeters less than the diameter of the line to be extruded; when the diameter of the line to be extruded is 20 to 25 millimeters, the diameter of the main body 1 is 1 to 5 millimeters less than the diameter of the line to be extruded; When the wire diameter of the wire is 25 to 35 mm, the diameter ...
