Abstract

The invention provides a hydraulic transmission and control system for a press machine. The system is characterized by comprising a centralized-control combined valve block, as well as a small hydraulic cylinder, a large hydraulic cylinder, a main oil tank and a sub oil tank which are connected with the centralized-control combined valve block. The system thoroughly changes the traditional hydraulic transmission and control system for a press machine; the original pressure applying / pressure maintaining valve block and sequence control valve are combined into a uniform 'combined valve block'; the traditional slide valve control is changed into advanced cartridge valve control; the original speed regulation-free / throttling speed regulation feeding is changed into volume speed regulation; according to the system provided by the invention, an oil temperature is regulated in an air-cooling manner for replacing water-cooling regulation.

Description

technical field [0001] The invention provides a hydraulic transmission and control system, which belongs to the field of fluid transmission and control. The application field is pressure machinery, and is especially suitable for ironing and embossing machines in the leather industry. Background technique [0002] The original press control system of the same kind is slide valve type or discrete valve block type, scattered in different positions, so not only the wiring is messy, the operation and maintenance are cumbersome, but also the pressure loss is large and there are potential safety hazards. In addition, the original form of speed regulation without work or throttling speed regulation, sometimes does not meet the process requirements. In addition, the original method has high oil temperature, high noise, poor reliability and high maintenance cost. Contents of the invention [0003] Purpose of the invention: The present invention provides a hydraulic transmission and...
