Abstract

PURPOSE:To make it possible to prepare a fine clay block and provide a rigid ceramic from said block, by increasing an inner pressure by striking a counter pile from the inner side of the clay to the outside before releasing said clay block from a mold when molding the clay in the mold before baking. CONSTITUTION:A pile is struck in order to increase an inner pressure. In this case, a ball cap makes the inner pressure to be directed to the whole and a scalene-triangular cap gives a directionally to the inner pressure. After the pile is struck, this mark remains even if the pile is removed, and a ceramic becomes more rigid and, thus, it results to the reduction of costs.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) In the case of a liquid, the internal pressure can be increased by applying pressure from the outside or by expanding something inside. The same applies to solids such as clay.

(2) Pile driving increases internal pressure because it is solid.”
After this, even if the stakes are removed, the marks will remain and the overall appearance will not change.

The clay becomes solid and the space remains.

(3) The cap with ball in Fig. 2 is this r pile drive A.
In order to make the characteristics more effective, the direction of the internal pressure is directed toward the whole.

When it is desired to give directionality to the internal pressure, a cap with a scalene triangular prism is used as shown in Figure 3.

(4) Extracting the piles after ``staking'' provides additional advantages: it strengthens the ceramic and at the same time saves material. Also, keeping air inside the ceramic increases the heat retention effect.

(5) ``Pile driving'' can be done by applying strong pressure instantly with a hammer or the like, or by slowly applying continuous pressure.

(6) Application (A) Manual production is inefficient for mass production of Kawara, so it is automatically made using molds. Then.

3. The present invention solves this problem and makes it possible to make strong tiles.

(B) When a large amount of the r-piling 1 of the present invention is introduced into the process of making bricks, bricks that contain a large amount of air, have heat retaining properties, are lightweight, and are strong.

(C) Ceramic engines for automobiles are ideal in terms of thermal efficiency, but because the material is brittle, they are still at the research stage for some time.

Figure 1 is in the middle of "r piling".

Figure 2 shows a cap with a spherical tip that directs pressure throughout the interior during pile driving.

Figure 3 shows a triangular prism cap with directional pressure6.
Both figures are cross-sectional views.

Claims (4)

[Claims] (1) When molding clay with a mold before baking,
Before taking it out of the mold, internal pressure is increased from the inside to the outside of the clay, making it a denser clay lump and making it a more solid ceramic. (2) Internal pressure is increased by driving piles, as shown in Figure 1.
A concrete example using a flat clay plate is shown. (3) There are cases in which piles of various materials are left in the clay as they are driven, and cases in which the piles are pulled out and a space is left in the clay. (4) When driving a pile by attaching a small ball or triangular prism cap as shown in Figures 2 and 3 to the pointed end of the pile, the internal pressure can effectively move in all directions or in any direction. When the stake is removed after driving, the cap is left in place.
