Abstract

The invention discloses a multi-connecting-rod hydraulic press which comprises a press body, a hydraulic cylinder, an auxiliary sliding block, a main sliding block and two same multi-connecting-rod branch chains. A cylinder barrel of the hydraulic cylinder is hinged to the press body, the free end of a piston rod in the hydraulic cylinder is hinged to the auxiliary sliding block, the auxiliary sliding block is arranged on the press body in a sliding mode, the main sliding block is arranged on the press body in a sliding mode, and the sliding direction of the main sliding block is the same as that of the auxiliary sliding block. The two same multi-connecting-rod branch chains are symmetrically arranged relative to the hydraulic cylinder, and the multi-connecting-rod branch chains are connected with the auxiliary sliding block and the main sliding block. The multi-connecting-rod hydraulic press has the advantages that three-time reinforcement is realized through a reinforcement mechanism of the multi-connecting-rod branch chains, so that output pressure which can be obtained only by connecting a plurality of same oil cylinders in parallel can be generated by driving of only one oil cylinder.

Description

technical field [0001] The invention relates to a multi-link hydraulic press. Background technique [0002] The hydraulic press realizes pressure control by controlling the hydraulic oil pressure, and the control method is simple and easy to realize. [0003] The disadvantage is that if you want to obtain higher pressure, method one: increase the oil pressure; method two: increase the diameter of the oil cylinder; method three: connect multiple oil cylinders in parallel. [0004] The above methods all have deficiencies. Method 1 increases the oil pressure, which requires higher sealing, which increases the risk of oil leakage; Method 2 increases the size of the hydraulic cylinder, which increases the cost; Method 3, connecting multiple oil cylinders in parallel, not only improves cost, and the synchronous control of multiple oil cylinders is difficult and difficult to realize. Contents of the invention [0005] The present invention proposes a multi-link hydraulic press,...
