Description
Technical Field
The utility model belongs to the technical field of dies, and particularly relates to an insulated wire extrusion die, an extruder and an insulated wire production system.
Background
The insulated wire extrusion apparatus has a die for coating a flat or profiled wire with an ultra-thin Polyetheretherketone (PEEK) insulation layer.
Regarding the design of a machine head and a mould for extruding a flat structure, quality problems such as eccentric glue discharge, uneven thickness, separation of an insulating layer and the like of the polyether-ether-ketone insulating resin often occur. Key to these problems is the die pressure factor. The pressure of the round die opening of the insulated wire with a common round wire structure is uniformly distributed in the circumferential direction due to the round structure, so that the quality problem is not easy to occur. Insulation of a flat or irregularly shaped structure is otherwise not easy, and the extrusion pressure is uneven due to the unequal lengths of the die openings in the horizontal and vertical directions, so that the outer die is deviated, and the quality of the produced insulated wire is difficult to control.
