Description

TECHNICAL FIELD

[0001] The utility model relates to cable production equipment technical field, concretely relates to a wire passing die holder device for the wire inlet of a cabling machine head. BACKGROUND

[0002] At present, when the Ф630 cabling machine is used to produce the CRAFT conductor platform back field (high, medium and low field) superconducting cable, the superconducting cable surface needs to be overlapped and wrapped with steel belts, and the wrapping overlapping is relatively high. In order to make the steel belt wrapping reach the lap joint rate required by the process, the steel belt walking angle of the Ф630 cabling machine wrapping head needs to be adjusted to be very close to the wrapping head support sleeve and nut assembly.
