Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cutting a surface of a semi-plastic material before steam curing to a desired size in a manufacturing process of an ALC panel.

[0002]

2. Description of the Related Art Conventionally, when manufacturing an ALC panel,
The raw material slurry is poured into a mold in which reinforcing bars are set and foamed, and after a lapse of a predetermined time, the mold is removed, and the surface and the side surface of this semi-plastic material are cut into a predetermined size and cut into a predetermined thickness. Then, it is charged into an autoclave and steam cured at high temperature and high pressure to obtain a product. In order to cut the surface of the semi-plastic material, the semi-plastic material 1 is usually mounted on the carriage 5 as shown in FIG.
Mounted on the support plate 6 that is in contact with the end side surface of the support plate 6,
The carriage 5 is moved from the front end portion of the surface to the horizontally extending piano wire or the horizontal cutting blade 2 for cutting.

However, the end upper edge 1a of the semi-plastic material 1 is often cut off during this cutting, and depending on the extent of this, the smoothness of the surface is reduced or repair is required,
That portion must be cut and removed, which is not only troublesome, but also has a problem of degrading the quality of the product. As a countermeasure, there is a method of making a horizontal cut at the end portion, but this work is difficult to automate because a special tool is used, and there is a problem that it is troublesome because it is performed by a skilled worker.

DISCLOSURE OF THE INVENTION The present invention provides a cutting method for cutting the surface of a semi-plastic material, which does not cause a loss of the end portion without trouble.

[0005]

SUMMARY OF THE INVENTION According to the present invention, when a semi-plastic body and a horizontal cutting blade are moved relative to each other to cut the surface of the semi-plastic body to a desired size, the end surface of the semi-plastic body is previously cut. The end surface is cut so as to form an inclined surface whose inclination angle is substantially equal to the above-mentioned predetermined dimension and whose inclination angle is equal to or smaller than the angle of the cutting blade, and when a piano wire is used instead of the cutting blade, an inclined surface of 45 degrees or less is used. It is cut so as to be formed.
Further, when cutting these inclined surfaces, the piano wire is inclined in the moving direction of the semi-plastic material and cut.

[0006]

When the surface of the semi-plastic material is cut, the end surface of the semi-plastic material has a predetermined size, and the end face is substantially equal to the predetermined size, and the tilt angle is less than the angle of the cutting blade or less than 45 degrees. By cutting so as to form,
Unreasonable shear stress does not act on the semi-plastic material at the terminal end, and as a result, it is possible to prevent the terminal end from missing. When the cutting blade is used, the angle of the inclined surface is equal to or larger than the angle of the cutting blade, and when the piano wire is used, the effect is small when the angle of the inclined surface is 45 degrees or more. Further, when cutting the inclined surface, the piano wire is inclined with respect to the moving direction of the semi-plastic material and cut, whereby it is possible to prevent the end portion of the inclined surface from being missing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory view showing an example of cutting the surface of the semi-plastic body 1 by the method of the present invention, and the semi-plastic body 1 has a width of 1500 m.
m, length 6000 mm, and height about 630 mm are mounted on the trolley | bogie 5, and the terminal part is hold | maintained by the vertical support plate 6. The cutting blade 2 for cutting the surface of the semi-plastic body 1 to a height of 600 mm has a height of 600 mm from the upper surface of the carriage 5 as the height of the tip blade.
It is fixed at a position of mm, the cutting edge is horizontal, and the inclination angle α is about 15 degrees and is inclined upward. A screw 3 for discharging the cut scraps is arranged at a position close to and above the entire surface. Further, the terminal end portion of the semi-plastic body 1 is formed with a piano wire in advance to form an inclined surface having an inclination angle β of about 13 degrees and has a terminal height h.
Is cut to have a thickness of 605 mm.

In this state, when the semi-plastic material 1 is moved in the direction of the arrow and the surface thereof is cut by the cutting blade 2, the semi-plastic material 1
The terminal is cut to a predetermined height and no chipping occurs. Further, when the angle β of the inclined surface was about 20 degrees, a part of the terminal was slightly missing. FIG. 2 shows an example in which the surface of the semi-plastic material 1 is cut with a piano wire 4, and the end portion of the semi-plastic material 1 has an inclination angle θ in advance.
Forms an inclined surface of about 30 degrees, and the terminal height h is 605 mm
It is cut so that In this state, when the semi-plastic material 1 is moved in the direction of the arrow and the surface thereof is cut by the piano wire 4, the end of the semi-plastic material 1 is cut to a predetermined height and no chipping occurs. No dropout occurred even when the angle β of the inclined surface was about 40 degrees, but at the tilt angle of about 50 degrees, a part of the terminal was dropped off.

In FIG. 3, the end portion of the semi-plastic material 1 is connected to the piano wire 7
It is a plan view for explaining the method of cutting with, the piano wire 7 is stretched on the machine base 8, the inclination angle γ is inclined about 20 degrees in the horizontal direction in which the semi-plastic body 1 moves, and the base portion 7b in the vertical direction. The inclination angle β (see FIG. 1) inclines toward the tip portion 7a from about 13 degrees. And the height h at the end of the semi-plastic body 1
Is 605 mm. When the semi-plastic material 1 is moved in the direction of the arrow in this state, the end portion of the semi-plastic material 1 is cut at a height h = 605 mm and an inclined surface angle of about 13 degrees.
At this time, the lower side of the piano wire 7 cuts first, so that there is almost no omission or crack at the terminal end, and even if a small amount occurs, it is the side that is deleted and does not affect the product.

[0010]

As described in detail above, when cutting the surface of the semi-plastic material, when cutting the surface of the semi-plastic material,
By cutting the end surface of the semi-plastic body so that the end face is substantially equal to the predetermined dimension in advance and the inclined angle is less than the angle of the cutting blade or 45 ° in the case of a piano wire, Unreasonable shear stress does not act on the semi-plastic material at the terminal end, and as a result, it is possible to prevent the terminal end from missing. When cutting the inclined surface, if the piano wire is inclined with respect to the moving direction of the semi-plastic material and cut, it is possible to prevent the end portion of the inclined surface from being cut off, and automation is easy.
