Embodiment 2

[0038] The difference from Embodiment 1 is that the first pre-drive control module and the second pre-drive control module can also be composed of a pre-drive control module, and as an independent controller with the first winding frequency converter control circuit and the second The winding inverter control circuit is connected to control the pre-drive of the first winding inverter and the second winding inverter. The pre-drive control module includes a disc-changing deceleration control module, a pre-drive operation control module, and a roll diameter reset control module. The disc-changing deceleration control module receives a deceleration and disc-changing signal from a PLC controller to perform disc-changing deceleration control. The drive operation control module receives the pre-drive command from the PLC controller to perform pre-drive operation control, and the coil diameter reset control module receives the coil diameter reset command from the PLC controller to perf...

Abstract

The invention relates to an automatic coil replacement control system of a double-variable-frequency drawbench, a method thereof and a coil diameter calculation method. The automatic coil replacement control system comprises a take-up device. The take-up device comprises a first coiling spool, a second coiling spool, a first motor, a second motor, a first coiling frequency converter, a second coiling frequency converter and a programmable logic controller (PLC). The PLC controls the first coiling frequency converter and the second coiling frequency converter to drive the first and second motors to move so that the first and second coiling spools can be driven to take up lines. The take-up device further comprises a pre-driving control module which controls the first and second coiling frequency converters. The first coiling frequency converter drives the first motor to move, thereby controlling pre-driving of the first coiling spool. The second coiling frequency converter drives the second motor to move, thereby controlling pre-driving of the second coiling spool. The control program is simpler, smooth transition of the automatic coil replacement process is achieved, the linear velocity keeps synchronous, the coiling tension is constant, and the stability of the control system is improved.

Description

technical field [0001] The invention belongs to an automatic roll-changing control system for double-frequency conversion wire drawing machine equipment, and relates to an automatic drawing and winding control system and processing method for metal materials. Background technique [0002] Wire drawing machine is one of the main processing equipment in the machinery industry. It mainly processes copper (steel) wires into thin wires of various specifications. It consists of a pay-off motor, a take-up motor and a wire-drawing motor. With the continuous maturity and development of control technology, frequency converter, PLC and touch screen are widely used in wire drawing machine equipment. [0003] In the field of wire drawing machine application, automatic roll change involves a complete set of overall solutions, including inverters, PLCs, touch screens, etc. Automatic roll change involves roll diameter calculation and PID adjustment functions. The existing automatic roll c...
