Abstract

The invention discloses a control system for a hot die forging press, which includes a frequency converter, a main motor and a CPU module. An external braking unit is connected to the frequency converter, and a braking resistor cabinet is connected to the external braking unit; the CPU module passes The RS485 module communicates with the frequency converter, and the local I / O module, Mod-bus module, CC-link module and power module are respectively installed on the expansion base board and communicate with the CPU module respectively; the remote I / O module is connected to the CC-link module , remote temperature module and analog module; the signal output terminals of each monitoring point of the press are respectively connected to the signal input terminals of the remote I / O module; the signal input terminals of the remote temperature module are connected to several temperature sensors, and the signal input terminals of the analog module Connected to the pressure sensor. The invention is applied to a hot mold press, which can avoid the problems of excessive bus voltage of the frequency converter and cumbersome wiring of the CPU module caused by frequent braking.

Description

technical field [0001] The invention relates to a control system, in particular to a control system of a hot die forging press, and belongs to the technical field of press control. Background technique [0002] In the prior art, there is a control system for a hot forging press, which is mainly used for thermoforming workpieces. It includes a three-phase power supply, a frequency converter, a main motor and a CPU module. The three-phase power supply passes through a circuit breaker and a leakage protector in turn. , The AC reactor is connected to the AC power input end of the inverter, the AC power output end of the inverter is connected to the main motor, the output shaft of the main motor is connected to the flywheel drive of the press, and the flywheel and the eccentric shaft of the press are torqued through the clutch Transmission, the eccentric shaft of the press rotates synchronously with the flywheel. [0003] Its disadvantages are: the flywheel has a relatively high...
