Dual clamping arrangement for connecting rod fracturing machine

摘要

An improved fracturing machine for fracturing a connecting rod preform includes clamping mechanisms at both upper and lower portions of the preform. Wedges lock the clamps onto the preform during fracturing. The top and bottom clamps provide a cleaner fracture at the fracture plane. The bottom clamp preferably includes rear and forward members which may move along an arc-shaped interface to allow adjustment of the clamping contact position. The top clamp preferably includes rear and forward clamp portions which are spaced slightly such that the forward clamp can twist slightly to accommodate the shape of the individual preform.
