Embodiment Construction

[0013] Preferred embodiments of the present invention are described in detail below.

[0014] The invention provides a control system of a double frequency conversion type wire drawing machine, the schematic diagram of the working equipment of the wire drawing machine is attached figure 2 As shown, it includes main components such as a wire drawing machine, a first motor and a second motor, a frequency converter, a tower wheel, a sensor, and a pulling frame. The first motor controls the speed of driving the pulling frame, and the The second motor controls the speed of driving the take-up reel; it also includes a double frequency conversion controller, which respectively controls the first frequency converter D1 and the second frequency converter D2 through different high-speed pulses; the first frequency converter D1 and the first motor IM1 is electrically connected to control the speed of unwinding the wire from the wire drawing machine; the second frequency converter D2 is ...

Abstract

The invention provides a control system of a dual-frequency converting type wire drawing machine, which is composed of a plurality of main components, such as a wire drawing machine, a motor, a transducer, a cone pulley, a sensor and a pull traction frame. The system makes use of the dual-frequency converting controller to take the high speed pulse as the speed signal of the transducer; the two transducers are respectively connected with the wire putting and the wire collecting motor, and are used to realize the operation of the wire putting and the wire collecting from the wire drawing machine; the dual-frequency converting controller receives the main engine speed signal, the wire collecting speed signal and the tension control signal by two sensors; the two sensors use the proximity switch. Adopting the proposal, the invention improves the automatization control programme, and reduces the workload of the workers; the sensor uses the proximity switch to control the speed and tension, thus the reliability of the device is improved.

Description

technical field [0001] The invention relates to a double frequency conversion type wire drawing machine, in particular to a control system of the double frequency conversion type wire drawing machine. Background technique [0002] Wire drawing machine is a commonly used wire and cable production equipment. It uses the easy stretchability of metal wires to stretch metal wires with thick diameters into slender wires through multiple die sets in a certain ratio. It is widely used. Used in the production of copper, iron, steel, alloys, etc. [0003] The key to the control of wire drawing equipment lies in the speed control of the take-up end. The take-up part adopts a take-up wheel device. With the increase of the take-up length, the take-up diameter becomes larger and larger. When it is larger than the pay-off speed of the driving wheel, the wire will be pulled off immediately and the production will stop. Therefore, the core of the control task is to ensure that the take-up s...
