Widely used in coilers and Carrousel coilers in production lines such as CL, GL, PL, and RL.
· The strength of the mandrel main shaft is good;
· The axial wedge of the mandrel is usually made of cast copper, and the friction performance of the sliding surface is good;
The coiler mandrel is mainly composed of main shaft, wedge,pull rod, segment, expansion and contraction cylinder etc., which is also a relatively common form, the reel drives the wedge to move axially along the main shaft of the reel through the pull rod,and the relative sliding between the wedge and the segment causes expansion and contraction of the diameter of the reel, and relies on the hook of the wedge to reset the segment.
