Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic presses, in particular to a 200T multi-action hydraulic press. Background Art

[0002] Hydraulic press is a type of hydraulic press. It uses special hydraulic oil as the working medium and a hydraulic pump as the power source. The hydraulic oil enters the cylinder / piston through the hydraulic pipeline by the force of the pump. Finally, the hydraulic oil circulates in the oil tank through a one-way valve to make the cylinder / piston circulate and work, thereby completing a certain mechanical action as a kind of machine for productivity. Hydraulic presses are mainly divided into metal forming hydraulic presses, bending hydraulic presses, stretching hydraulic presses, punching hydraulic presses, powder (metal, non-metal) forming hydraulic presses, press-fitting hydraulic presses, extrusion hydraulic presses, extrusion molding, etc.

However, the existing hydraulic presses, especially those with a capacity of 200 tons, are very large in size, occupy a large area, and have relatively slow response and movement, resulting in relatively low production efficiency.
