Problems solved by technology
[0002] The cold-rolling mill is a process equipment for cold-rolling waste pipes with ring holes. The traditional rotary feeding control motors have mechanical transmission and hydraulic transmission. They also have complex structures and long manufacturing cycles. Two The DC motor is used as the driving force for turning and feeding, which can make the mechanical structure of the turning and feeding system simpler and the manufacturing cycle shorter. The rotation angle and output torque of the slewing and feeding motors are closed-loop controlled to realize the stepless continuous change of the motor rotation angle and quick start and stop

The invention discloses an all-digital cold rolling mill rotation feeding controller comprising a rotation main control unit used for controlling a rotary motor, a feeding main control unit used for controlling a feeding motor, and a multi-channel power output unit. The all-digital cold rolling mill rotation feeding controller is designed as a part mounted in a standard box, uses standard three-phase alternating voltage of 380V +1 N, supplies two paths of direct-current output voltage and current, is used for armature and excitation, and is adaptable to direct-current separately-excited motor control. Compared with the prior art, the all-digital cold rolling mill rotation feeding controller can perform closed-loop control on rotating angles and output torques of the rotary motor and feeding motor so as to realize stepless change of rotating angles and rapid start and stop of the motor.
Description
technical field [0001] The invention relates to the technical field of automatic control of cold-rolled pipe mills, in particular to an all-digital cold-rolled pipe mill rotary feeding controller. Background technique [0002] The cold-rolling mill is a process equipment for cold-rolling waste pipes with ring holes. The traditional rotary feeding control motors have mechanical transmission and hydraulic transmission. They also have complex structures and long manufacturing cycles. Two The DC motor is used as the driving force for turning and feeding, which can make the mechanical structure of the turning and feeding system simpler and the manufacturing cycle shorter. The rotation angle and output torque of the slewing and feeding motors are closed-loop controlled to realize the stepless continuous change of the motor rotation angle and quick start and stop. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention...
