C-Expanding

This is a single-purpose segmented shaped tool marked "C" or "E". It is suitable for expanding the tube diameter.

Complete assembly is composed of internal fingers, mandrel and barrel in which the individual parts are assembled. This type of tool contains only expanding fingers. This means that it is possible to put pressure the shaped area from the inside, which allows us to expand the diameter of the tube

Arbor C-Expanding

Arbor

This component is inserted to the machine as an independent unit. Using the machine piston the mandrel is moved, this then causes the fingers to open up. In this way there is a dilation or subsequent calibration of the tubes.

From a construction perspective this product is made in two variants depending on the inner diameter of the tube, 8 or 6 segment with differing angles.

Fingers C-Expanding

Fingers

The movement of the mandrel cause the segments to be expanded to the required diameter of the tube. The mandrel is inserted through the correct fixed section on the individual segments of the inner fingers, which then apply a force to the inner side of the shaped area.

Barrel C-Expanding

Barrel

Barrel is produced from two flanges which create a space for the expanding fingers.

Optional extra equipment can be adjusted to the end of the tubes, which allows greater variability in the length of the shaped area. The finish of the tube is available at customer request only with the complete set of tools including the barrel.
