Beschreibung
Zusammenfassung:	The utility model discloses a heat preservation device of an electric heating straightening machine, which comprises a heat preservation pipe capable of being opened and closed on one side, a heat preservation cover opening and closing controller used for controlling the heat preservation pipe to be opened and closed, and a heat preservation pipe stretching and retracting control mechanism used for controlling the heat preservation pipe to stretch and retract towards a sectional material straightening working position. The opening direction of the heat preservation pipe faces the sectional material straightening working position. By arranging the thermal insulation pipe capable of being opened and closed on one side and the thermal insulation pipe stretching and retracting control mechanism used for controlling the thermal insulation pipe to stretch and retract towards the sectional material straightening working position, the heat loss of the sectional material in the electric heating straightening link is r
