Description

Special-shaped cable sheath extruder head for remote terminal detection diagnosis control system

Technical Field

The invention relates to the field of cable extruder heads, in particular to a special-shaped cable sheath extruder head for a remote terminal detection, diagnosis and control system.

Background

In the existing production and manufacture of electric wires and cables, an outer sheath is generally formed by extrusion molding through an extruder head. The extruder head body is internally fixed with a machine core, and the outer side of the extruder head body is provided with a heating system, so that plastics can be plasticized in the extrusion process, and an annular plastic flow is formed under the flow separation of the machine core. The plastic flows through the die, and is restricted by the die extrusion port and a subsequent cooling system to coat the outer surface of the cable core with the plastic, so that the wire cable with the outer sheath is manufactured. The processing mode is very suitable for extrusion molding of circular cables, but when the inner die and the outer die of the die are deviated, the inner die, the outer die and the machine core are positioned on the same axis by adjusting deviation screws from four directions of up and down, left and right, so as to realize extrusion molding of wires and cables.

In the existing power and information transmission control system, a multifunctional composite cable is required to be used. If the special-shaped cable for the remote terminal detection diagnosis control system is formed by combining a plurality of functional unit cables, when the traditional extruder head is used for carrying out outer sheath extrusion molding on the special-shaped cable for the motor stator temperature measurement, large and high-power equipment is required to be used for completing the outer sheath extrusion molding, the energy consumption is increased, meanwhile, a large amount of plastic is required to fill a large amount of thick circular structures, the material waste is serious, the occupied space is occupied during the installation, the volume of electric control equipment is enlarged, and the cost is increased. Therefore, in order to solve the above problem, it is necessary to arrange a plurality of functional unit cables in parallel, and it is necessary to change the round cables to a flat shape.

In the extrusion process of the outer sheath of the special-shaped cable for the flat remote terminal detection diagnosis control system, if a traditional adjustable deviation extrusion machine head is used, plastic fluid moves in a circular ring shape in the machine head due to the fact that a machine core of the traditional adjustable deviation extrusion machine head is a conical cylinder, and finally the plastic fluid is forcibly converted into flat extrusion at an extrusion port. The process that the cone of the plastic fluid is suddenly changed into the flat shape makes the flow passage space complicated, so that the plastic fluid has the phenomenon of unbalanced pressure at an extrusion port, the design size of the special-shaped cable outer sheath for measuring the temperature of the motor stator is difficult to grasp, the phenomenon of convex and concave unevenness of the appearance of the cable can be caused, and the ideal effect can be achieved only by adjusting the cable for many times by an operator. In addition, when the deviation is adjusted, in order to keep the extrusion pressure uniform, the adjustment needs to be carried out in a state of extruding and adjusting at the same time, so that the operation difficulty is greatly improved, time and labor are wasted, a large amount of raw materials are wasted, and the energy consumption and the cost are increased.

In the invention patent with the application number of 201210053977.0, an offset-free flat cable extruder head is provided, wherein inner and outer dies are all set to be integrally identical and square, and the inner and outer dies are installed in a die hole groove formed at the tail end of a machine core to realize offset-free operation of the inner and outer dies, so that the operation difficulty is reduced, and the labor intensity is reduced. However, the die hole slots formed in the core can increase the manufacturing difficulty of the device, and meanwhile, in order to realize the coaxiality of the inner die and the outer die, the die hole slots are required to be tightly attached to the inner die and the outer die, so that the installation and the disassembly of the dies are very difficult.
