Structure and function

of the hand activated Hydra expansion arbors and Hydra expansion chucks from Mytec -Hydraclamp-

Clamping: Safety Release: Power-activated: For this type, a clamping wrench 8 is used with which the clamping bolt 3 is screwed in for maximum expansion, or the full clamping force can be adjusted to the stop.

Safety: The stop also serves as stroke limiter, so that over-expansion or damage to the expansion sleeve 2 is not possible.

When screwing in the expansion bolt 3 the collet piston 4 is activated.
This causes the hydraulic fluid in the chamber system 7 to be pressed against the thin-walled expansion sleeve 2. At the same time, the expansion sleeve 2 uniformly expands radially over the entire chucking length both centrically and cylindrically.

Release: To release, clamping screw 3 is turned back to the starting position with the clamping wrench 8.
This triggers the pressure relief and the release of the expansion sleeve. Due to its inherent tension, the expansion sleeve returns precisely to its starting position.

Power activated: For power-activated hydraulic expansion tools from Mytec -Hydraclamp-, the clamping process is executed via the tensioning fixture of a machine. (See system spezification - activation types)
