Description

[Detailed Description of the Invention] [Industrial Application Field 1] The present invention relates to a method and apparatus for simultaneously cutting and crushing the ends of molded plates such as weir plates for use as architectural flooring materials, roofing materials, bridge road bottom materials, etc. In particular, the end of a molded plate such as a weir plate, which is made by integrally molding the bent portion of a flat plate of a required length with a predetermined interval in one direction to form a two-layered plate with an approximately T-shaped cross section. This invention relates to a method for simultaneously cutting and crushing parts and an apparatus therefor.

(Prior Art 1 Molded plates such as weir plates (e.g. deck plates, roof plates 1. However, when using a molded square corrugated steel plate, the concrete 1 to pouring surface is uneven, so the required slab thickness is When considering, four-part concrete I
・Because it is not used as a structural material, the weight of the floorboard becomes unwieldy.

In addition, in the normal deck play 1~, decking is laid on beams and the height of the convex part is added to the thickness of the slab, which increases the floor height and causes an increase in the total construction cost. Therefore, a deck plate was needed in which a folded portion with a T-shaped cross section was integrally formed, which was made up of two stacked steel plates folded at a predetermined interval in one direction on the lower surface of the steel plate. However, as a method for closing the end of conventional deck play 1~,
Japanese Patent Publication No. 50-27464 discloses a processing method in which the ends of the corrugated cross section are closed off-line after forming into a corrugated steel sheet. In addition, depending on the method of closing the end of the deck play 1, as shown in Japanese Patent Publication No. 1138/1983, the deck play 1 running through the mold consisting of the upper mold, the lower mold on the entry side, and the lower mold on the exit side is synchronized. Then run and tighten, and at a predetermined position, place the deck plate on the mold and use Cera L-L to cut and close the end while running, and after running, raise the upper mold and lower the lower mold on the exit side. There is also a method of closing the end of the decking brake for transporting the product decking plate.

[Problem 1 to be Solved by the Invention In the method for closing the end of Detsuki Play 1~, which is the prior art described in 4-, the prior art disclosed in Japanese Patent Publication No. 50-2746/1, Close one end each time, and in the case of J, turn the deck plate over and leave
The work involved closing one end, and since the length of the deck plate to be closed varied, all work was done manually, resulting in inefficiency and waste. Furthermore, the blockage at the end could not be flattened uniformly5.Furthermore, in the conventional technique shown in Japanese Patent Publication No. 1138/1983, a deck plate was formed into the shape of 1, and then cut to a fixed length within the line. At the same time, both ends of the cut opening are closed, but this requires a special mold, and in addition, closing the ends creates ridge lines and uneven parts. When the end of the deck plate is installed on the beam, it is unstable and the deck plate 1 itself has the drawback of making waves. In particular, in the above-mentioned conventional end closing method technology, the bent portion with a special cross-sectional shape, which is made of two stacked steel plates folded at a predetermined interval in one direction on the lower surface of the steel plate with increased rigidity, is integrated. In the case of molded deck plates,
There is a problem in that there is a high possibility that the so-called flat plate portion will be pressed in a combed or crumpled state.

[Means for Solving the Problems] The present invention aims to solve the above problems by transferring a continuous or discontinuous flat plate, and placing it into a molding machine at predetermined intervals in one direction. In a method of simultaneously cutting the ends of a molded plate, such as a weir board, in which the folded portion of two laminated plates having an approximately -1 character shape is integrally molded, the two laminated plates of the flat plate are A step of cutting a notch and forming a crush-inducing portion in which a portion to be bent and bent into a shape is cut to a desired length and a crush-inducing portion is simultaneously formed at a vertical portion of the two-ply plate portion; A process for forming a molded plate such as a weir board, etc., by using a molding machine to form a flat plate, and then crushing and simultaneously cutting the end of the molded plate using a press or the like using a crush-inducing part of the molded plate. A method for simultaneously cutting and crushing the ends, and a transfer device capable of transferring a continuous or discontinuous flat plate, and a folding portion that forms two stacked plates having approximately T-shaped cross sections at a predetermined interval in one direction are integrated. A molding machine is used to form a molded plate such as a weir plate, and before the molding in the molding machine, the part of the flat plate that can be bent into a two-ply plate shape is cut to a desired length, and the vertical part of the two-ply plate part is cut. A notch for forming a crush inducing part in the part that will become the part -〇- Cutting and crush inducing part forming machine, and a press machine that crushes the crush inducing part and crushes the end of the molded plate and simultaneously cuts the end part. The present invention is characterized by a device for simultaneously cutting and crushing the ends of a molded plate such as a weir plate.

Embodiment 1 Next, an embodiment of the technical means of the present invention will be described based on the drawings.

FIG. 1 is an explanatory diagram of an apparatus for implementing the present invention, and FIG. 2 is an enlarged plan view showing a part of a flat plate processed by the notch cutting and crush-inducing part forming machine shown in FIG. 1. Figure 3 is a perspective view of one embodiment showing the molded part shown in Figure 2, and Figure 4 shows the part that will be cut with a cutting machine in the next step after being molded in Figure 3 (in other words, FIG. 5 (a
) to (C1 is a partially enlarged perspective view showing an example of the shape of the end portion of the product of the present invention, and FIG. FIG. 7 is a partially enlarged side view showing an example of a state in which the ends of the molded plate are simultaneously crushed and cut.

Kikomei's molded plate cutting method and its cutting device continuously feeds out a continuous flat plate from an uncoiler '1, cuts the notch with a leveler 2, and cuts the notch with a pressure # inducing part forming a3 for easy processing. It is transferred to the cutting and crushing part forming machine 3. In addition, in the case of a discontinuous flat plate, the leveler 2 is not required.

The notch cutting and crushing inducing part forming machine 3 notches and cutting the R cotton product to a desired length to form it, and also forms a crushing inducing part in the vertical part 9' of the two-ply board part. Any cutting machine may be used as long as it is a notch cutting and crush-inducing part forming machine 3 that can simultaneously form the notch 10. However, this must not be a complete separation, but rather one that can be left partially uncut.

In other words, when cutting a section to an arbitrary length before bending and forming, the cut is not cut completely, but rather like a perforation, where there is a cut section and an uncut section. Calculate this in advance. This cutting is done using a press cutting machine, etc., so that when the final product is made, the part corresponding to the folded part is cut and all or part of the flat part remains uncut. Put it in about 1 or about 1.

In addition, if the end of the flat plate is cut into a notch of arbitrary width,
Easy to perform subsequent process operations such as bending press processing. For this reason, it may be necessary to cut it out together with other cutting parts in advance.

This means that the cut portion 7, which will eventually be formed into a bent portion 9, is cut while still in the flat state (see FIG. 2), and then bent and formed into a desired shape by a forming machine 4. This forming machine 4 drives the forming roll in multiple divisions so that the circumferential speed can be changed in multiple stages (the number of divisions can be selected in various ways depending on the complexity of the processed shape), and each It is possible to change the circumferential speed.

It goes without saying that this would be better if the molding was made more efficient, for example by slowing down the inlet side and fasting the outlet (1) side.

After being bent and formed by this forming machine 4, the portion remaining without being cut by the simultaneous cutting and crushing device 5, as described above, is the part that cannot be cut due to a flat plate shape when being bent and formed. Since some portion remains, this flat portion 8 is cut and crushed at the same time.

The crush inducing part 10 simultaneously cuts the flat plate as shown in FIG. When formed at a predetermined position and molded into a molded plate, it will have a bent bulge shape as shown in Figure 5 (a), but it will also have a notched shape as shown in side views (b) to (C). The form can be arbitrary.

Furthermore, as shown in FIG. 6, by providing projections 3b and 3c for forming drain holes or nailing holes at required parts of the mold member of the notch cutting and crushing inducing portion forming machine 3,
As shown in Figure 2.3, drain holes 11 are placed in the predetermined positions of the molding plate.
Alternatively, it is also possible to form a nailing hole 12.

Also, what is shown by 6 in Fig. 1 is an accumulator, which is used to adjust the difference in working time between the notch cutting and crush-inducing part forming process and the molding process, and is required to open the radius necessary for continuous operation. It is a part.

Note that the accumulator 6 is not required in the case of a discontinuous flat plate, and the simultaneous cutting and crushing machine 5 may be either a well-known stationary type simultaneous cutting and crushing machine or a running type simultaneous cutting and crushing machine. When loading the flat plate into the simultaneous cutting and crushing machine 5, the tip of the flat plate may be deformed. It is also conceivable to make sure that the setting can be made by pressing the button.Furthermore, it goes without saying that various devices, such as photoelectric switches, etc., may be provided as necessary to ensure safety.

[Effect 1 The above technical means of the present invention produces the following unique effects. That is, (1) Since the molding is carried out in the form of a continuous flat plate, it is extremely easy to obtain molded plates with particularly short dimensions (short lengths) for each intermediate period.

■Since the blade is molded in a continuous state, the top when molded, ],
The method of molding the product is stable for 7J.

■When forming a flat plate after cutting, there may be gaps between the front plate and the back plate to prevent slippage and other problems.Due to rain prevention, there may be gaps between the front plate and the rear plate, or there may be gaps between the front plate and the rear plate to prevent rain. Since it is not necessary to have a mold, the loss in molding work is significantly reduced.

■Since the plate is a flat plate, a simple cutting device is sufficient for cutting it before molding.Furthermore, since the portion to be cut after molding only needs to be cut and covered, an extremely simple cutting device can be used for cutting. Able to perform work.

(2) Since the crush-inducing portion is formed at the same time as the notch cutting of the flat plate, the crushing work of the end of the molded plate performed in the subsequent process can be performed easily, reliably, and with high efficiency.

■Since the ends of the molded plate are crushed and cut at the same time, the space required for the forming plate is small, and processing can be performed on a straight line, and the line length is short and processing time is shortened, making maintenance easier.
