Embodiment 1

[0030] refer to figure 1 , figure 2 , image 3 , Figure 4 , a winder control device for multi-pass drawing equipment, including a frequency converter, a motor, a winder, and a winder controller, the output of the frequency converter is connected to the motor, and the motor is connected to the winder through a transmission mechanism. A position sensor is installed on the winder, and a tuner for coordinating the working speed relationship of adjacent passes is installed between the finished product pass and the winder, and the winder controller 1 includes a winder deviation control module 2 , which is used to calculate the deviation control amount according to the position given value and actual feedback value of the tuner between the finished product pass and the winder, and its formula is as (2):

[0031] Δ G s = ( K sp + 1 ...

Embodiment 2

[0041] refer to figure 1 , figure 2 , image 3 , Figure 4 , the winder controller 1 of the present embodiment also includes a soft start control module 5, and the soft start control module 5 includes: a start setting unit 6, which is used to set the start of the winder when starting The given and feedback deviation of the position sensor is smaller than the actual deviation; the deviation reduction unit 7 is used to increase the given and feedback deviation within the set time limit, so that the given and feedback deviation is equal to the actual deviation. The deviation reduction unit 7 is an arithmetic increment unit, which is used to increase the given and feedback deviations by an equal amount within a set time.

[0042] The rest of the structure of this embodiment and the working process of the speed ratio adjustment module are the same as those of Embodiment 1.

Embodiment 3

[0052] The structure and working process of this embodiment are the same as those of Embodiment 2.

[0053] Take the 12-pass LZ12-560+SG800 wire drawing machine with 5.5mm incoming wire and 1.42mm outgoing wire as an example.

[0054] The transmission ratio of the finished product pass is 2.38, the transmission ratio of the winding machine is 2.04, select the speed ratio coefficient Ks=0.8, adopt the classic feedforward + PID control, and set the rapid stop time of the equipment to 6 seconds. When the wheel is empty (with an inner diameter of 400mm), the winding machine will break the wire; when the I-shaped wheel on the winder is full (the outer diameter is 800mm), the wire will fall after loosening. If the feed-forward + PID control modified by iterative algorithm is adopted, the I-shaped wheel on the winder will not break or fall off no matter whether the reel is empty or full, and the position of the tuner will basically remain unchanged.

[0055] Before adopting the star...

Abstract

The winder controller for multiple gate drawing apparatus includes frequency variator, motor, winder, and winder controlling unit. The frequency variator has output connected to motor, the motor is connected to the winder via transmission mechanism, the winder has installed position sensor, and one tuner is installed between the product gate and the winder for cooperating the work speed. The winder controlling unit includes winder deviation controlling module to calculate the deviation controlling amount based on the given position of the tuner and practical position from the position sensor. The winder controlling unit operates on the ''feedforward+PID'' control mode and has speed ratio parameter optimized through iterative algorithm. The present invention can improve the operation performance and fast stop performance of winder.

Description

(1) Technical field [0001] The invention relates to an electric control device for the production of metal products, in particular to a winder control device for multi-pass drawing equipment. (2) Background technology [0002] Drawing equipment (or linked wire drawing equipment) is a typical mechatronics product. In the production of metal products, its function is to extrude metal materials with larger cross-sections through The mold) is processed into various metal materials with different specifications and small cross-sections. The winding machine winds the finished wire on the I-shaped wheel, which is an important part of the drawing equipment. When working, the winding machine is driven by the AC motor through the transmission mechanism, and the operation of the AC motor is controlled by the frequency converter. Therefore, the operating speed of the winding machine is actually determined by the speed given value sent to the frequency converter. to decide. The previou...
