Problems solved by technology
[0002] At present, similar products produced in China use sizing dies. Since the sizing dies are stretched and shaped, they will damage the insulation layer of the cable to a certain extent, resulting in a certain internal stress inside the insulation layer during the sizing process.
The presence of stress greatly reduces the mechanical phase stability of the cable

The invention relates to a setting rolling wheel device for a micro-pore polytetrafluoroethylene film-lapped insulated phase-compensated cable. The setting rolling wheel device is mainly used for a precision lapping machine, and is used for controlling the outer diameter of a lapped cable insulating layer. The setting rolling wheel device comprises a fixed seat, a rolling wheel carrier, a rolling wheel group, an adjusting knob and a locking screw, wherein the fixed seat is provided with the rolling wheel carrier; the rolling wheel group is arranged in the rolling wheel carrier; the rolling wheel carrier comprises a rolling wheel carrier fixing seat, an adjusting knob installation seat and a rolling wheel support rod; the rolling wheel group comprises three rolling wheels which freely rotate and are arranged in a staggered manner; one end of each of the three rolling wheels is arranged on the pressing wheel carrier fixing seat through one universal spindle coupling and the other end is arranged at the end part of the adjusting knob through another universal spindle coupling; an outer thread is arranged in one end of the adjusting knob; the adjusting knob is arranged on the adjusting knob installation seat; the locking screw is arranged at the side of the adjusting knob installation seat; a cable outlet is arranged in the middle of the fixed seat; a fixing shaft is arranged on the fixed seat; and a fixing flange is arranged at the end part of the fixed seat.
Description
technical field [0001] The invention relates to a shaping pressing wheel device for wrapping insulated phase-stable cables with microporous polytetrafluoroethylene films. The product is mainly used on precision wrapping machines to control the outer diameter of the cable insulation layer after wrapping. Background technique [0002] At present, similar products produced in China all use sizing dies. Since the sizing dies are stretched and shaped, they will damage the insulation layer of the cable to a certain extent, resulting in a certain internal stress inside the insulation layer during the sizing process. The presence of stress greatly reduces the mechanical phase stability of the cable. Contents of the invention [0003] The object of the present invention is to solve the deficiencies in the prior art, and provide a shaping pressure wheel device for wrapping insulated and stable phase cables with microporous polytetrafluoroethylene film. By installing the shaping pres...
