Abstract
A frame for hydraulic apparatus includes at least three supporting pillars, a supporting assembly mounted on the supporting pillars and including a fixed die plate fixed to the supporting pillars, an adjustable die plate slidably fixed to the at least three supporting pillars and a core plate slidably fixed to the at least three supporting pillars and located between the fixed die plate and the adjustable die plate and a link mechanism mounted on the supporting assembly and coupling the core plate to the adjustable die plate. The fixed die plate, the core plate and the adjustable die plate each have a periphery sidewall, and include a first protrusion protruded from the periphery sidewall and extended along a circumferential direction thereof, and define an indentation adjacent to the first protrusion and further define a plurality of openings on the first protrusion interconnected with the indentation.
