Pay-off reel Tension reel Mandrel of the main structure form

The mandrel is the key part of hot rolling tension reel for coils. Coiling temperature is between 550 to 850 oC . The mandrel has mainly two types: link wedge type and double wedge type.
Unk wedge type can also be divided into two kinds: link wedge coupling drive and link wedge-spline drIve.

For link wedge-coupling type tension reel, the mandrel is mainly composed of rnandrel body, spreader bar, segment, link, wedge and spreading cylinder Spreader bar has multistage slopes and segment is supported by multistage wedge Segment is connected with spreader bar by link so segment does not drop off With compression spring in the middle of wedge, wedge can firmly contact segment and pyramid surface. There is a gap between the upper surface of wedge and segment, which can reduce the impact of coil head to mandrel during coiling coil. Mandrel body is installed on two bearings. Power is transmitted by crowned-teeth coupling in the rear. It is very convenient to dismantle, and due to there is no gear impact during working. mandrel rigidity is improved. Ita s very beneficial to control the dynamic tension.
