Description

[Detailed explanation of the invention] (Industrial application field) This invention was developed by vibrating steel wires up and down when the lightweight cellular concrete is in a semi-plastic state during the manufacturing process of lightweight cellular concrete panels (hereinafter referred to as ALC panels). The invention relates to a device for cutting to a predetermined thickness.

(Prior Art) ALC boards are widely used as building materials due to their advantages such as lightness and heat resistance. As it became more popular, it had a strong image of a flat surface, and the beauty of the processed and cut surfaces became emphasized and valued.

Conventionally, in the manufacturing process of ALC plates, reinforcing bars were placed in the formwork, and when the injected raw material slurry became semi-plastic, it was moved to a predetermined thickness by moving a support frame with steel wire stretched vertically. Cut into. The cut pieces are cured in an autoclave, and after curing, the ALC plate taken out from the formwork is further chamfered and grooved to obtain a product.

(Problem that the invention attempts to solve) However, in the device with the above configuration, none of the
This causes roughness on the cut surface of the ALC board, which increases the amount of base paint used when painting the surface, which leads to an increase in the cost of painting and finishing. There were drawbacks such as the need for equipment to clean dust that adhered to the ALC board.

Therefore, the purpose of this invention is to eliminate the unevenness of the ALC board surface in order to eliminate the above-mentioned conventional drawbacks, to make the outer surface smooth, to reduce the cost of painting and to improve the aesthetic appearance. The purpose of the present invention is to provide a cutting device.

(Means for Solving the Problems) In order to achieve the above-mentioned purpose, this invention is based on a device that cuts lightweight aerated concrete in a semi-plastic state to a predetermined thickness. One side end is rotatably supported on a support frame as a spindle, and the other side end is simultaneously moved in an upward and downward arc by a drive device to cut the steel wire while vibrating it up and down. It was designed to do so.

(Function) In this way, the present invention cuts the lightweight aerated concrete in a semi-plastic state while vibrating the steel wire up and down, so that the cut surface can be made smooth.

(Embodiment) Fig. 1 shows an embodiment of the cutting device of the present invention.
The figure is a schematic perspective view showing the state of the cut surface, and the figure b is a schematic perspective view showing the state during cutting. As shown in the figure, a cutting device in the thickness direction normally has a plurality of beds 2 on which semi-plastic lightweight aerated concrete 1 (hereinafter referred to as green cake) is placed, and the necessary cuts depending on the thickness of the sheet to be cut. Conventionally, a steel wire mounting plate 4 on which a steel wire 3 is stretched is fixed integrally to a mounting frame 5, and is moved on a rail 7 in the direction of the arrow in FIG. It is designed to cut into plates of a constant thickness. Since the steel wire mounting plates 4 are provided above and below the fresh cake 1 to be cut, the bed 2 that receives the lower side of the fresh cake 1 is synchronously moved when the steel wire mounting plate 4 passes, for example. Two pieces are lowered to allow the steel wire mounting plate 4 to pass through.

However, in the present invention, as shown in FIG. 2, a pair of upper and lower steel wire mounting plates 4 are supported by supporting shafts 8 protruding from both ends of the steel wire mounting plates 4, respectively, on bearings 9 (see FIG. 1) attached to the mounting frame 5. A tie rod 11 connects the upper and lower levers 10 fixed to the support shaft 8 so that the pair of upper and lower mounting plates 4 can be rotated in conjunction with each other on the opposite side of the support shaft 8. To give tension to each of the steel wires 3, one end is hooked directly to the support plate 4 (lower side in the figure), and the other end is removably locked to the support plate 4 on the opposite side with a hook bolt 12. A spring 13 is interposed between the support plate 4 and the support plate 4. On the other hand, the upper support shaft 8
The lever 10 attached to the mounting frame 5 is composed of an L lever 10a, and a tie rod 16 is eccentrically connected to the L lever 10a and a disk 15 of a motor 14 installed on the mounting frame 5, converting so-called rotational motion into linear motion. It makes up the crank mechanism.

In such a configuration, when the mounting frame 5 is moved in the direction of the arrow (see FIG. 1b) via the rail 7 while driving the motor 14, the tie rod 16 is caused to reciprocate in a substantially horizontal direction by the so-called crank mechanism. Then, the L lever 10a is actuated to further vibrate the tie rod 11 in the vertical direction. Therefore, the raw cake 1 is cut into plates of a constant thickness while the pair of upper and lower steel wire mounting plates 4 are rotated in an arc shape to vibrate the tensioned steel wire 3 up and down (see Figure 2b). Ru.
In addition, when the attachment frame 5 passes, the bed 2 which was holding the bottom of the raw cake 1 to be cut by the cutting device is synchronously lowered by two pieces, for example, to prevent the steel wire attachment plate 4 from passing. making it possible. It should be noted that as long as the cutting device and the raw cake are moved relative to each other, there is no problem in moving either of them. Since the raw cake 1 is cut while vibrating the steel wire 3 up and down in this manner, the cut surface is cut smoothly without any unevenness.

(Effects of the invention) As explained in detail above, according to the invention, the unevenness of the cut surface of the raw cake is eliminated and the outer surface is made smooth, which reduces the cost of painting and finishing.
It is effective in improving the appearance image.
