Description

Non-adjusting extrusion die of special-shaped cable for measuring temperature of motor stator

Technical Field

The utility model relates to a cable extrusion equipment, in particular to motor stator temperature measurement is with exempting from of abnormal shape cable transfers extrusion tooling.

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 motor stator abnormal shape cable for temperature measurement just comprises a plurality of functional unit cable combinations, when using traditional extruder head to this kind of motor stator abnormal shape cable for temperature measurement oversheath extrusion moulding, need use large-scale and powerful equipment just can accomplish, increased the energy consumption, simultaneously, thick circular structure needs a large amount of plastics to fill, and the material waste is serious, and occupation space when the installation, causes the bulky and increase in cost of electrical control equipment. 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 process of extruding the outer sheath of the special-shaped cable for measuring the temperature of the flat motor stator, the appearance of the cable is possibly uneven, and the ideal effect can be achieved only by adjusting the die for many times by an operator. When the deviation is adjusted, in order to keep the extrusion pressure uniform, the adjustment needs to be carried out under the state of adjusting while extruding, so that the operation difficulty is greatly promoted, 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.
