Clamping tool.

摘要

Disclosed is a clamping tool comprising a clamping head (22) which is light, has a high Young's modulus, exhibits a high fatigue resistance, and is free from cracking and scattering of the cracked pieces. The clamping tool permits an operator to operate the clamping tool under a safe environment, and lessens the burden given to the operator, leading to an improved working efficiency. The clamping tool comprises a clamping head (22), a cylinder member fit with the edge portion of the clamping head, a ram member mounted to and movably arranged within the cylinder member, a first die member (311) mounted to the clamping head (22), and a second die (312) member arranged to face the first die member (311) and moved by the ram member toward and away from the first die member (311), wherein at least the clamping head (22) is formed of a composite material prepared by dispersing at least one kind of a reinforcing material (23) selected from the group consisting of ceramic fibers, ceramic whiskers and ceramic particles into a matrix metal (24) consisting of an aluminum alloy or a magnesium alloy. <IMAGE>
