て硬化せしめることによって成形されている。``Prior Art'' and ``Problems to be Solved by the Invention'' When forming a ceramic honeycomb, generally, the first step is to form a honeycomb core, which is a support base of the ceramic honeycomb, and to this honeycomb core, for example,
It is formed by attaching a liquid ceramic material by impregnating or coating it, and then sintering and hardening the attached ceramic material.

久的な曲げ変形による折曲部を容易に形成することがで
きる素材が多用されている。Therefore, the base material of the honeycomb core, which is the support base of the ceramic honeycomb, can be formed using an easy-to-form expansion molding method.
It is possible to extremely easily form a honeycomb core consisting of a planar collection of cells with a substantially regular geometric shape, and it is also easy to form a honeycomb core with a small cell size, which is also inexpensive. For reasons such as aluminum foil,
Materials such as plastic sheets, which have a relatively low melting point and can easily form bent portions by permanent bending deformation, are often used.

、空洞部の減少を図り、強度の向上を図っていた。By the way, when a ceramic honeycomb is formed using a honeycomb core formed from such a material as a base material as a supporting matrix, it is easy to obtain a ceramic honeycomb in which each cell has a substantially regular shape. The area previously occupied by the honeycomb core is completely hollowed out, and the strength of that area is significantly reduced. , drilling a large number of small-diameter holes in the base material in a sheet-like state,
A honeycomb core is formed using these base materials, and when a ceramic material is attached by impregnation, etc., the ceramic material attached in a layered manner to both wall surfaces of the honeycomb core is bonded at the hole portion, thereby reducing the number of cavities. , aiming to improve strength.

コアが高価となる難点を有していた。However, since the base material has a characteristic that bends are easily formed due to permanent bending deformation, it is difficult to form a honeycomb core with regular cell shapes by stretch forming means.
In advance, a large number of holes are drilled in the base material at predetermined positions, for example, in a honeycomb core in which the holes are formed, in a regular position such as a bent part of the cell wall, an open end of the cell, where the hole does not overlap the cell wall, etc. Therefore, the work to drill a large number of holes is troublesome and requires a lot of man-hours, and when each joint is fully joined during heavy loading, it is difficult to , the holes regularly drilled in a predetermined positional relationship block the communication parts formed in each joint to communicate between cells, and these parts become completely hollow, so each joint In order to prevent complete cavitation of the material, for example, adhesive should be applied to the region other than the hole so that the region other than the hole is partially joined to the extent that the joint does not separate during expansion. As a result, it is necessary to form an adhesive layer, and therefore, the work of forming the adhesive layer is troublesome, and the honeycomb core, which is a support matrix, is difficult to mold and the honeycomb core is expensive.

安価に成形することができる 。The present invention has been made in view of the above-mentioned circumstances, and its purpose is to use materials such as aluminum, which has a relatively low melting point, easily forms bent portions due to permanent bending deformation, and is inexpensive. Although the support base is a honeycomb core formed from materials such as foil or plastic sheet, it is easy to remove the ceramic material attached in layers to both walls of the honeycomb core at joints and other parts. Similarly, it is extremely easy to create a ceramic honeycomb with few cavities, excellent strength, and a substantially regular shape of each cell.

たものである。The present invention has been made to achieve the above-mentioned object, and the technical solution is first to create a bending method that has a relatively low melting point and is caused by permanent bending deformation. easy to form parts,
For example, an unexpanded honeycomb core is formed by using a material such as aluminum foil or plastic sheet as a base material, and stacking a predetermined number of these base materials so that the joints are alternately shifted by half a pitch. Next, before expanding, communication holes are bored at appropriate locations in each joint and other parts of this unexpanded honeycomb core, and the unexpanded honeycomb core is formed directly or in a linear shape. After cutting into predetermined lengths in the direction perpendicular to the joint, the honeycomb core is formed by stretching the ceramic honeycomb in the stacking direction, and the ceramic material is attached to the honeycomb core. A ceramic honeycomb is formed by sintering and hardening the ceramic material.

Since there are communicating holes drilled at appropriate locations in the honeycomb core in an unexpanded state, when a liquid ceramic material is attached to the honeycomb core by impregnation or coating, for example, The ceramic material deposited in layers on both surfaces of each part of the honeycomb core is bonded through the ceramic material that has entered into each communication hole during deposition.

Honeycomb cores made of materials such as the Ceramic that has been adhered and hardened in a layered manner has the presence of cavities in areas where communicating holes existed, where the ceramic penetrates into the communicating holes during adhesion and is firmly bonded by the ceramic that is hardened in that state. Ceramic honeycombs with excellent strength can be obtained.

有する効果は顕著にして大なるものがある。"Effects of the Invention" As will not be described in detail above, according to the method for manufacturing a ceramic honeycomb according to the present invention, the melting point is relatively low, bends are easily formed due to permanent bending deformation, and it is inexpensive. For example, although a honeycomb core made of materials such as aluminum foil or plastic is used as a support base, ceramic material is attached in layers to both walls of the honeycomb core using an easy molding method. Ceramic honeycombs can be bonded at appropriate locations of joints and other parts, and similarly, there are few cavities, excellent strength, and the shape of each cell is substantially regular. It has significant effects, such as being able to be formed at a low cost and eliminating the drawbacks of conventional honeycomb manufacturing methods of this type.

セラミックハニカムの製造方法。The base material is made of a material such as aluminum foil or plastic that has a relatively low melting point and is easy to form a bent part by permanent bending deformation, and a predetermined number of these base materials are used to form a joint. a process of forming an unexpanded honeycomb core by stacking the honeycomb cores so that they are alternately shifted by a half pitch, and an expanding process at appropriate parts of each joint and other parts of the unexpanded honeycomb core. After previously going through the step of drilling a communicating hole and the step of cutting the unexpanded honeycomb core into predetermined lengths in a direction perpendicular to the joint formed directly or in a linear shape, the The method includes a step of expanding in the bonding direction to form a honeycomb core serving as a supporting body of the ceramic honeycomb, and a step of attaching a ceramic material to the honeycomb core, and then sintering and hardening the attached ceramic material.
