Problems solved by technology

[0004] Disadvantages of the status quo of proportional linkage of the frequency converter on the straight wire drawing machine: program writing and program control are completed through PLC, PLC programming and calculation are more complicated, and a lot of data is collected by on-site commissioning personnel during the programming process. The accuracy is low. In addition, the compiled program can be used on this machine, but it cannot be used on another machine after being copied. The versatility is poor, and it is difficult to popularize and apply.

Abstract

The invention relates to the technical field of wire drawing machines, in particular to a straight wire drawing machine system. The system comprises a PLC and two or more wire drawing units, wherein each wire drawing unit comprises a frequency converter, a motor, a gearing and a bobbin; and a tension detecting device is arranged between adjacent two wire drawing units. The invention provides the straight wire drawing machine system; and a formula of a wire drawing rule is compiled and is stored in the frequency converter, so that a general electrician can debug a machine according to the specification of the frequency converter only by inputting corresponding data into the frequency converter. Therefore, the system has very high practicability and points out a direction for the development of the frequency converter special for wire drawing; PLC programming and debugging work of the wire drawing machine is greatly simplified after a program is stored in the frequency converter; and high practicability is achieved.

Description

Technical field: [0001] The invention relates to the technical field of wire drawing machines, in particular to a straight wire drawing machine system. Background technique: [0002] A wire drawing machine is a processing machine that transforms a large-diameter metal wire into a small-diameter metal wire through multi-pass drawing. The straight wire drawing machine generally includes two or more wire drawing units. The wire drawing unit includes a motor that drives the wire barrel to rotate and a frequency converter that is electrically connected to the motor. The frequency conversion function of the frequency converter is used to realize the speed regulation of the motor. [0003] At present, the proportional linkage scheme of the straight wire drawing machine system is as follows: it is composed of PLC, touch screen, feedback device and frequency converter; the function of the touch screen is man-machine dialogue, and the operator inputs data to the PLC through the touch ...
