題点があった。In the above-mentioned prior art, the method and apparatus for cutting a molded plate, a method for cutting after molding into an arbitrary shape, in the case of an apparatus, a complicated and high-performance cutting apparatus is required.
In the case of cutting a deck plate, a roof plate, or the like having a special T-shape, for example, there is a defect that the shape is deformed and the commercial value is extremely poor. When the thickness is changed during the processing of the continuous flat plate, a loss of the plate occurs. In the case of continuous molding, the processing members of the molding machine become complicated, and the value of the molding machine becomes expensive. Further, in a method and an apparatus for cutting after cutting into an arbitrary length in a flat plate shape (this corresponds to the case of a discontinuous one), it takes time to adjust the roll by switching the plate thickness. Troubles (collision, sheet overlap, etc.) occur in the roll slip molding machine. The top and end shapes cannot be made as desired, and to solve this requires the use of a large number of rolls, which makes the equipment itself long. In addition to the various problems described above, in the case of each of the above-described conventional technologies, the end portion of the molded plate after molding is easily crushed in the vertical portion of the two laminated flat plates. Since there is no crush-inducing portion, such as a bent portion or a cut portion, which can be performed, there is a problem that the end portion crushing of the molded plate performed in the subsequent process cannot be performed easily, reliably, and efficiently.

ことはいうまでもない。Next, embodiments of the technical means of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory view of an apparatus for carrying out the present invention, FIG. 2 is an enlarged plan view showing a part of a flat plate processed by the notch cutting and crush induction part forming machine shown in FIG. FIG. 4 is a perspective view of one embodiment showing a place where the one shown in FIG.
FIG. 5 is an enlarged plan view showing a portion to be cut by a cutting machine in the next step after being molded in FIG. 3 (in other words, a portion in a flat plate state that is not folded into a two-layered plate shape), FIG. (A) to (c) are partially enlarged perspective views showing an example of the shape of an end portion of the product of the present invention, and FIG. 6 is an example of a notch cutting and crush inducing portion forming type (lower die) in the present invention. FIG. The method for cutting a molded plate of the present invention and the cutting device for the same are used to continuously feed a continuous flat plate from the uncoiler 1, and to perform the notch cutting by the leveler 2 and the processing by the crush induction part forming machine 3 so as to facilitate the notch cutting and cutting. It is transported to the crush induction part forming machine 3. In the case of a discontinuous flat plate, the leveler 2 is not required. The notch cutting and crush inducing section forming machine 3 cuts and cuts to an arbitrary length to be molded into a final product, and crush inducing section 10 is formed in a vertical portion 9 ′ of the two-ply plate portion.
Notch cutting and crush inducing portion forming machine 3 capable of simultaneously forming
Any cutting machine may be used. However, this is
It must be able to not be cut completely, but cut partially. In other words, when cutting to an arbitrary length before bending and forming, instead of cutting the cut completely, there is a way to make a cut part and a part that is not cut, such as a perforation commonly called Perform this calculation in advance. In this cutting, a part corresponding to the bent part is cut when the product finally becomes a product, and a cut is made in one step by a press cutting machine or the like so as to leave all or part of the flat part without cutting. Or in several steps. In addition, when the end of the flat plate is cut into a notch at an arbitrary width, the next process operation such as bending press working is easily performed.
For this reason, it may be necessary to cut out together with another cutting part in advance. This is because the cut portion 7 finally formed into the bent portion 9 is cut in a flat plate state (see FIG. 2).
Next, it is bent and formed into a desired shape by the forming machine 4. The molding machine 4 performs multiple division driving (the number of divisions can be selected in accordance with the complexity of a processing shape, variously in terms of design, so that the peripheral speed of the molding roll can be changed in multiple stages).
Each peripheral speed can be changed. Needless to say, this is better if the molding efficiency is improved by, for example, making the inlet side slower and the outlet side faster. After being bent and formed by the forming machine 4, a portion which is not cut by the cutting device 5 and which is not cut, which is a portion which is not bent as a flat plate when bent and formed, remains without being cut. , This flat part 8
Is to cut off. As shown in FIG. 2, the crush inducing section 10 simultaneously cuts and cuts a flat plate by the notch cutting and the projection 3a (including a press type or a punch type) of a mold member of the crush inducing section forming machine 3. When formed at a predetermined position on a flat plate and molded into a molded plate, it is bent and bulged as shown in FIG. 5 (a), but otherwise cuts as shown in FIGS. 5 (b) to (c). The shape can be arbitrary. Further, as shown in FIG. 6, by providing the protrusions 3b and 3c for forming a drain hole or a nail punching hole at a required portion of the mold member of the notch cutting and crushing inducing portion forming machine 3, the second and the second are provided. Three
As shown in the figure, it is also possible to form a water draining hole 11 or a nail punching hole 12 at a predetermined position on the molded plate. In addition, what is indicated by 6 in FIG. 1 is an accumulator, which is a stagnant portion necessary for continuous operation by adjusting the difference in working time between the notch cutting and crushing portion forming step and the molding step. . The accumulator 6 is not required in the case of a discontinuous flat plate, and the cutting machine 5 may be any of a well-known stationary cutting machine or a traveling cutting machine. At this time, since the leading end of the flat plate may be deformed, in such a case, it is conceivable to provide a pressing roll or the like immediately before the cutting machine 5 so that the plate can be set securely. Further, it is needless to say that various devices, for example, a photoelectric switch and the like are provided as necessary in order to ensure safety.

易、かつ確実、高能率に行うことができる。The following technical effects are produced by the above technical means of the present invention. That is, since molding is performed in a state of a continuous flat plate, it is extremely easy to obtain a molded plate having a particularly short dimension (short) of each unit. Since molding is performed in a continuous state, the top and end molding dimensions during molding are stable. When molding after cutting a flat plate, work was done with a gap between the front plate and the rear plate to prevent slippage and other obstacles, but the interval was set to form a continuous flat plate. Without having to do so, the loss of the molding operation is significantly reduced. Since the cutting before molding is a flat plate, a simple cutting device may be used, and the portion to be cut after molding may be cut only on the flat plate portion. it can. Since the crush-inducing portion is formed at the same time as the notch cutting of the flat plate, the crushing operation of the end portion of the molded plate performed in the subsequent step can be performed easily, reliably, and efficiently.
