Abstract

The present invention is the monitoring system for metal extruding hydraulic press and belongs to the field of hydraulic machinery technology. The monitoring system consists of industrial control computer, display terminal, controller, hydraulic press sensor and rotary coder. Structurally, the monitoring system features that the industrial control computer is connected with the display terminal and the programmable controller; and that the industrial control computer mainboard is provided with light isolated communication card connected with the digital display of pressure and the digital display of stroke and analog amount output card connected with proportional amplifier board for controlling the proportional variable pump of the hydraulic press. The present invention has stepless digital control of speed, stroke and pressure of hydraulic press, no PLC module and lowered production cost.

Description

technical field

[0001] The invention belongs to the technical field of hydraulic machinery, in particular to a monitoring system for a metal extrusion hydraulic machine. Background technique

[0002] At present, the known hydraulic press control systems are touch screen + PLC mode. This mode is only to input (display) some process parameters on the touch screen, such as: preset stroke upper and lower limit, holding pressure value, etc., and the data in PLC is single Point transmission, unable to precisely control the speed, stroke and pressure during the operation of the press. This technical defect affects the monitoring of the metal extrusion hydraulic press and affects the precision control of the hydraulic press. Contents of the invention

[0003] The invention provides a metal extrusion hydraulic press monitoring system to solve the technical problems in the known technology.

[0004] The metal extrusion hydraulic press monitoring system is equipped with an analog o...
