Abstract

The invention provides a mechanical and hydraulic composite energy-saving cylinder for a long idle stroke and a short pressure stroke. A segmented feeding mode is adopted for the composite energy-saving cylinder. The whole working process is divided into an idle stroke quickly-downward stage and a low speed boosting stage. In the idle stroke quickly-downward stage, a motor is adopted to drive a thread pair to rotate so as to make a drive system move downwards quickly; after the low-speed boosting stage is entered, an oil cylinder is adopted to drive a piston rod to move downwards, and low-speed boosting is achieved. The mechanical and hydraulic composite energy-saving cylinder has the advantages of being high in working efficiency, good in forming effect, simple in structure, convenient to assemble and maintain and the like.

Description

technical field [0001] The invention belongs to the technical field of mechanical and hydraulic composite cylinders, and in particular relates to a mechanical and hydraulic composite energy-saving cylinder for long idle stroke and short pressure stroke. Background technique [0002] At present, the working process of many industrial equipment driven by hydraulic cylinders is mainly divided into two parts: the empty stroke downward stage and the low-speed boosting stage. Different working stages have different requirements for the movement speed and pressure of the working mechanism. In the downward stage of empty stroke, the hydraulic cylinder needs to be able to move downward quickly, which is beneficial to save empty stroke time and improve productivity. In the low-speed boost stage, these devices require the hydraulic cylinder to have low-speed boost capability. The entire working stroke of these industrial equipment driven by hydraulic cylinders is all driven by hydraul...
