Abstract
(EN)

The present disclosure provides an oil hydraulic press including a support frame, at least one main cylinder assembly and at least one fixed die table. The at least one main cylinder assembly and the at least one fixed die table are disposed in the support frame. A pressing mechanism is formed between the at least one main cylinder assembly and the at least one fixed die table. The support frame is in an annular or ring-like shape and is configured for fixing the at least one main cylinder assembly and the at least one fixed die table. The main cylinder assembly and the fixed die table can be fixed by the support frame, which forms a ring-like structure, can be operated in one, two or multiple sets in parallel, and all can realize pressing manufacture. The oil hydraulic press has less components, reduced material consumption and low manufacturing cost.
