Abstract
Description
本發明是關於一種透過修整設備來矯直線材或帶狀材料的方法,該修整設備具有能在通過其間之材料的對向兩側偏移並作用的矯直輥,其中部分矯直輥會自動根據一模型來設定以符合直線度的要求,該模型係依據材料的輸入數據以及在該材料通過該修整裝置的期間所傳送的材料與修整裝置的資料隨機判定,其中至少一個矯直輥的位置會基於該前述通過該修整裝置期間所接收到的數據而被連續調整,該數據是代表所達到的直線度。The present invention relates to a method for straightening straight or strip-shaped materials through a dressing device. The dressing device has straightening rollers that can shift and act on opposite sides of the material passing between them, and some of the straightening rollers will automatically Set according to a model to meet the straightness requirements. The model is randomly determined based on the input data of the material and the data of the material and the trimming device transmitted during the material passing through the trimming device, in which the position of at least one straightening roller It will be continuously adjusted based on the data received during the passage through the trimming device, and the data represents the straightness achieved.
這樣的方法被描述在DE-A-196 53 569中。然而,該文件僅非常一般地描述,將在矯直過程中所測量到的產品及/或過程資料連線輸入到模型中並將該模型改變,但並沒有詳細說明對此所必要的測量。所以並不清楚,該模型能否或是在某程度上可以得到關於被矯直最終產品的確切幾何形狀之結論。Such a method is described in DE-A-196 53 569. However, this document only describes in a very general manner, inputting the product and/or process data measured during the straightening process into the model and changing the model, but it does not specify the necessary measurements for this. So it is not clear whether or to some extent the model can draw conclusions about the exact geometry of the final product being straightened.
本發明的目的在於提供一種用於自主方法的封閉迴路,藉以矯直未知或變化曲率的直線度。該方法透過高度可靠性來保障被矯直線材所謀求的直線度。The object of the present invention is to provide a closed loop for an autonomous method, whereby straightness of unknown or varying curvature can be straightened. This method guarantees the straightness sought by the straightened straight material through high reliability.
這將透過先前所述的方法而達成,其中測量以下數據:(i)作用在該矯直輥的力會在該矯直輥本身被測量其大小與方向,及/或;(ii)在該材料穿過該矯直輥配置的通過過程之前或之後的溫度,及/或;(iii)測量在每個矯直輥之後該材料的位置,並將所獲得的測量值輸入到控制該可調整矯直輥之設定的模型中。This will be achieved through the method described previously, in which the following data is measured: (i) the force acting on the straightening roller will be measured in the size and direction of the straightening roller itself, and/or; (ii) in the The temperature before or after the material passes through the straightening roll configuration, and/or; (iii) Measure the position of the material after each straightening roll, and input the obtained measurement value into the adjustable control In the set model of the straightening roll.
有利的是在(ii)在每個矯直輥或每個矯直塊出口處測量材料溫度。It is advantageous to measure the temperature of the material at (ii) at the outlet of each straightening roll or each straightening block.
透過配置在矯直輥之軸承螺栓的應變計適當地執行作用在該矯直輥上力的測量(i),該應變計測量在軸向、垂直及/或水平方向的彎曲力矩。The measurement (i) of the force acting on the straightening roll is appropriately performed by a strain gauge arranged on the bearing bolt of the straightening roll, which measures the bending moment in the axial, vertical and/or horizontal directions.
溫度的測量(ii)檢測出被引入該矯直物件中的變形能量。透過此測量也可以校正進入模型的材料性質。這是可能的,即僅在矯直過程開始或在校準矯直裝置時執行此測量。The temperature measurement (ii) detects the deformation energy introduced into the straightened object. Through this measurement, the properties of the materials entering the model can also be corrected. It is possible to perform this measurement only at the beginning of the straightening process or when calibrating the straightening device.
透過在矯直輥的調整方向,材料與通過軸偏差的測量來適當地執行在每個矯直輥之後材料位置的測量(iii)。對此,可使用已知的光學或非接觸性(如磁性)的測量方法。這也適用於對通過的線狀材料上所發生的振動進行適當測量,其測量值同樣輸入到控制可調節矯直輥的模式設定中。可以想見的是,位置測量(iii)僅在以校準為目的程序開始時執行,當在驅動過程作用在矯直輥上力的測量是足以執行本發明的方法時。The measurement of the material position after each straightening roll (iii) is appropriately performed by measuring the deviation of the material and the passing axis in the adjustment direction of the straightening roll. For this, known optical or non-contact (such as magnetic) measurement methods can be used. This also applies to the appropriate measurement of the vibration that occurs on the passing linear material, and the measured value is also input into the mode setting for controlling the adjustable straightening roller. It is conceivable that the position measurement (iii) is only performed at the beginning of the program for the purpose of calibration, when the measurement of the force acting on the straightening roller during the driving process is sufficient to perform the method of the present invention.
有利的是,材料陸續通過兩個如上所述的修整裝置,其中一個修整裝置具有水平配置的矯直輥,且另一個修整裝置具有垂直配置的矯直輥。Advantageously, the material successively passes through two dressing devices as described above, one of which has a horizontally arranged straightening roller, and the other has a vertically arranged straightening roller.
