[Industrial Field of Application] The present invention relates to a method for manufacturing a laminated metal plate. [Prior Art] As a well-known method for manufacturing a laminated steel plate, a resin film and two metal plates are preheated, and then the resin film is stacked between the two metal plates and pressure bonded using a roll. 58−
Although disclosed in No. 203051 and the like, such methods may have drawbacks such as low plate thickness accuracy (uniformity), which may pose a quality problem. [Object of the Invention] The present invention has been made to advantageously solve these drawbacks. [Structure and operation of the invention] The gist of the present invention is to manufacture a laminated metal plate by heating a resin film and two metal plates in advance, overlapping the resin film between the metal plates, and pressing the resin film with a roll. The present invention relates to a method for manufacturing a laminated metal plate, which is characterized in that the temperature of the resin film is measured and the tension of the resin film is controlled based on the measured temperature while the resin film is laminated with a metal plate. That is, as a result of the inventor's study on variations in the thickness of laminated metal plates, it was discovered that the temperature of the resin film has a large effect on tension control. In other words, if the tension of the heated resin film is excessive, the thickness will decrease due to film elongation.
This can lead to shrinkage and breakage, and if the tension is too low, it can lead to meandering and wrinkles in the film.
It has become clear that this causes variations in the thickness of laminated metal plates. Specifically, the commonly used thickness is 0.4~
Figure 1 shows the relationship between tensile strength and temperature for 0.6 mm polypropylene and nylon-6 films. Due to adhesive strength, etc., polypropylene should be heated to a temperature of 100°C or higher, and nylon-6 to a temperature of 150°C or higher before lamination. It can be seen that the tensile strength of the resin film is 1/3 to 1/4 of that at room temperature or less. Therefore, the tension that can be applied is naturally less than this tensile strength. However, as for the stable range for adhesion, it is best to control the tension to about 30% or less of the tensile strength at each temperature in order to prevent thickness reduction and width shrinkage due to film elongation.
In addition, the tension should be at least 7% to prevent the film from meandering. In addition to such tension control of the resin film, by controlling the tension of the resin film by the temperature of the metal plates to be stacked and the temperature of the stacking rolls, it is possible to obtain a more precise plate thickness. It is preferable to control the tension of the film by taking into consideration the thickness of the metal plate, the threading speed, etc., since the accuracy of the plate thickness can be further improved. Next, production examples for carrying out the present invention will be given.
In FIG. 2, metal band coils 2 and 2a attached to payoff reels 1 and 1a are respectively unwound and guided to heating furnaces 3 and 3a, and stacked on rolls 4 and 4a.
lead to. On the other hand, the resin film coil 5 is unwound, the film 5 is preheated in the heating furnace 6, and while the tension is controlled by the tension meter roll 7, it is guided between the metal plates (bands) 2, 2a of the overlapping rolls 4, 4a, and crimped. Then, it is cooled by a cooling device 8 and wound up by a tension reel 9. The tension control of the resin film 5 is performed by measuring the temperature with a film plate thermometer 10 and controlling based on the measured value. Plate thermometer 11, 11 if necessary
The temperature of the metal plate is measured by a, and the tension of the resin film 5 is controlled in consideration of this value. Next, the tension control sequence will be explained with reference to FIG. The temperature measurement results of the resin film plate thermometer 10 and, if necessary, the metal plate thermometers 11 and 11a are guided to the resin film tension calculation device 12.
The type and size of the resin film are introduced through the setting device 16, the type and size of the metal plate are introduced as necessary, the tension of the film is determined, the tension is guided to the tension control device 13, and the thyristor of the payoff frame of the film is introduced. A payoff reel drive motor 15 is controlled via a control device 14 to control the tension of the film. In the figure, 17 is a film tension manual setting device, 7 is a tension meter roll that measures the current film tension, and 18 is a tension calculation device. Next, examples of the method of the present invention will be listed together with comparative examples.
