Beam wedge type mandrel
Coilers are widely used in production lines such as SPM, TLL, RCL, and GL. · When the reel is in perfect circle, there is no gap between adjacent segments; · A pre-compression spring is installed in the segment, and the segment is not loose; The reel of the beam wedge coiler is mainly composed of main shaft, pull rod, segment,radial wedge, axial wedge, and an expansion and contraction cylinder,it is divided into two structural type: with gripper and without gripper. The reel with gripper structure is generally used for winding the unit with thick strip, and the steel sleeve or paper sleeve can be used to complete the winding through the belt wrapper. The mandrel without gripper is mainly used to wind thin strip by belt wrapper. The reel drives the wedge-shaped block to move axially along the main shaft of the reel through the pull rod, and the relative sliding of the interlocking slope between the wedge-shaped block and the segment causes expansion and contraction on the diameter of the reel, and the segment is reset by the spring. Main technical parameters: Perfect circle Dia.:φ468，φ508，φ610，φ762 Max. coil width: 2600mm Thickness of strip: 1.2~12.7mm
