Abstract

The invention discloses a control system of a hot die forging press. The control system comprises a frequency converter, a main motor and a CPU module. An external brake unit is connected to the frequency converter, a brake resistor cabinet is connected to the external brake unit, the CPU module is in communication with the frequency converter through an RS485 module, a local I / O module, a Mod-bus module, a CC-link module and a power module are arranged on an expansion substrate and in communication with the CPU module, a remote I / O module, a remote temperature module and an analog quantity module are connected to the CC-link module, the signal output ends of monitoring points of the press are connected to the signal input end of the remote I / O module, a plurality of temperature sensors are connected to the signal input end of the remote temperature module, and a pressure sensor is connected to the signal input end of the analog quantity module. The control system is applied to the hot die forging press, and the problems that as braking is frequently carried out, the voltage of a bus of the frequency converter is excessively high, and wiring of the CPU module is complex are solved.

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...
