Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention provides a method for cutting molded plates such as pull weir plates (e.g. 7' Tsuki Pray 1-, Roof Ply 1. The present invention relates to a cutting device, and in particular to a cutting method and a cutting device that can be used to cut a molded plate such as a weir plate from a flat plate by easily crushing the ends of the molded plate.

(Prior Art) In conventional cutting of molded plates such as weir plates, continuous flat plates were continuously molded using a press or the like, and then cut into arbitrary lengths.

It is also practiced to cut a flat plate to an arbitrary length and then mold it into a required shape.

[Problem to be Solved by the Invention 1] In the above-mentioned prior art methods and devices for cutting molded plates, in the case of methods and devices that cut the molded plate after forming it into an arbitrary shape, ■ Cutting devices are complicated and have high performance. You will need something, especially
For deck plates, roof plates 1, etc., for example, when cutting special 1°-shaped items, the deformation occurs and the commercial value is significantly inferior.

■When changing the thickness of a continuous flat plate during processing, plate loss occurs. In the case of continuous molding, the parts processed by the molding machine become complicated, and the price of the molding machine increases.

In addition, in methods and equipment that cut the flat plate to arbitrary lengths and then mold them (this corresponds to the case of non-continuous pieces), (it takes time to adjust the rolls when changing the top plate pieces).

■ 1- Trouble (collision, temporary molding, etc.) occurs in the Luslip molding machine.

■The shape of the top and 1-1~ requires J, which cannot be done (
7. To solve this problem, it is necessary to use a large number of rolls, and the device itself becomes long.

In addition to various problems, in the case of each of the above-mentioned conventional techniques, it is easy to crush the end of the molded plate after molding at the vertical part of the two stacked flat plates. Since there are no crush-inducing parts such as folded parts or cut parts, there is a problem in that the end part of the molded plate cannot be easily, reliably, and efficiently crushed in a subsequent process.

[Means for Solving the Problems 1] The present invention aims to solve the above-mentioned problems by transporting continuous or discontinuous flat plates, and using a molding machine to space them at predetermined intervals in one direction so as to have a cross section of approximately 1 character. When forming a molded plate such as a weir board, which is composed of a bent part that becomes a two-ply board and a board part that does not become a two-ply board, the part that can be bent into a two-ply board shape is cut into an arbitrary length. At the same time, a notch is cut to simultaneously form a crush-inducing portion in the vertical portion of the two-ply plate portion. The inducing part forming process, one culm in which this notched flat plate is molded into a substantially single-shaped cross section with a molding machine, and then the part that was not cut in the previous notch cutting and crushing inducing part forming process. A method for cutting a molded board such as a wainscot board, which comprises a cutting step, and a transfer device capable of transporting a continuous or non-continuous flat plate, and two sheets having an approximately 4-shaped cross section with a predetermined interval in one direction. When forming a molded plate such as a weir board, which consists of a bent part that becomes a stacked board and a board part that does not become a two-ply board, the part that can be folded and bent into a two-ply board shape is cut to an arbitrary length, and the two boards are A notch cutting and crushing inducing part forming machine that simultaneously forms a crushing inducing part in the vertical part of the stacked plate part, and a molding machine that bends and shapes the notched cut flat plate into a substantially single-letter cross-sectional shape. The present invention is characterized by a cutting device for a molded plate such as a weir plate, which is comprised of a cutter and a cutter for cutting an uncut portion of a plate portion that does not become a two-ply plate of the flat plate.

[Example] Next, an example 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 carrying out the present invention, and Fig. 2 is a 1J enlarged plan view showing a part of the flat plate processed by the notch cutting and crushing light guide part forming machine shown in Fig. 1. , Fig. 3 is a perspective view of one embodiment showing the molded part shown in Fig. 2;
The figure shows the part that will be cut with a cutting machine in the next step after being molded in Figure 3 (in other words, the part that remains in a flat plate state without being bent into a two-layered plate shape Gj) η Enlarged plan view , 5th
Figures (al to C) are partially enlarged perspective views showing examples of the shape of the end of the product of the present invention, and Figure 6 is a cutout cut and collapse-inducing part forming mold (lower part) according to the present invention. FIG. 4 is a plan view showing an example of a mold.

The molded plate cutting method and cutting device of the present invention continuously feeds out a continuous flat plate from an uncoiler 1, and a leveler 2
Then, it is transferred to the notch cutting and crush-inducing valve forming machine 3 for easy processing. In addition, in the case of a discontinuous flat plate, the leveler 2 is not required.

The notch cutting and crush-inducing portion forming machine 3 performs a molding process on the final product. A crush inducing part 10 is cut in the vertical part 9' of the two-ply board part by notching it to a length of an arbitrary size.
As long as it is a notch cutting and crush-inducing product forming machine 3 that simultaneously forms ( ), a J or Eel cutting machine may be used. However, this does not mean cutting it off completely, but rather leaving it partially uncut.

To put this another way, when cutting to a desired length before molding, the bend is not a complete cut, but rather a cut part and an uncut part, similar to what is commonly called a perforation. J. Do the sea urchin calculations in advance. This cutting is done using a press cutting machine or the like so that when the product is finally cut, the part corresponding to the folded part will be cut and all or part of the flat part will remain uncut. It can be added in a process or several processes.

d3. If the end of the flat plate is cut to an arbitrary width with a notch, it will be easier to perform the next process such as bending and pressing. For this reason, it may be necessary to cut it out together with other cutting parts in advance.

The cut portion 7, which will eventually become the bent G' portion 9 after being molded, is cut while it is still a flat plate (see Figure 2), and then bent into the desired shape using the molding machine 1. is molded. This forming machine 4 drives the forming roll in multiple divisions so that the circumferential speed can be changed in multiple stages (it is conceivable that the number of divisions can be selected depending on the complexity of the processed shape). The circumferential speed of can be changed.

It goes without saying that it would be better if the molding efficiency was improved by, for example, discharging from the inlet side and speeding up the outlet side.

After the forming machine 4 bends and forms, the cutting device 5 continues to cut the remaining portion as described above. , so this flat part 8 is used as the cutting part.

Note that the crush inducing section 10 simultaneously performs the notch cutting process shown in FIG. It is formed at a predetermined position on a flat plate as shown in FIG.
Is it a bulge-like shape?
The shape can be arbitrary, such as a notch shape as shown in c).

Furthermore, as shown in FIG. 6, projections 3b and 3c for forming drainage holes or nailing holes are provided at required locations on the mold member of the notch cutting and crush-inducing product forming machine 3. It is also possible to form drain holes 11 or nailing holes 12 at predetermined positions in the molded plate as shown in the second and third figures.

Also, the one shown at 6 in Figure 1 is an Agicomb mulletator.
This is a stagnation part that is necessary for continuous operation while adjusting the difference in working time between the notch cutting and crush-inducing part forming process and the molding process.

Note that the Agicomb mulcher 6 is not necessary in the case of a discontinuous flat plate, and the cutting machine 5 may be either a well-known stationary type cutting machine or a running type cutting machine. Sera 1~'? When cutting, the tip of the flat plate may be deformed, so in such a case, install a presser foot or the like just before the cutting machine 5 to ensure secure setting. Furthermore, it goes without saying that various devices, such as photoelectric switches, etc., may be installed as necessary to ensure safety.

[Effects] The above technical means of the present invention produces the following unique effects. (1) Since it is molded in the form of a continuous flat plate, it is extremely easy to make 1 q of short τ1 method (short length) molded plates for each single unit.

■Since it is molded in a continuous state, the molding process of 1 hep and 1 ~ during molding is stable.

■When molding a flat plate after cutting, the distance between the front plate and the rear plate was increased to prevent slips and other problems, but now it is possible to form a continuous flat plate. Since there is no need to provide a gap, the loss in molding work is significantly reduced.

■Since the plate is flat, a simple cutting device can be used to cut it before molding.Furthermore, since the portion to be cut after molding only needs to be cut and covered, a very simple cutting device can be used to perform the cutting process. It can be carried out.

(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 formed plate performed in the last culm can be performed easily, reliably, and with high efficiency.
