関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for forming a pattern (so-called emboss pattern) on an extrusion molded product whose main raw material is a hydraulic substance, and more particularly, it relates to a method for forming a pattern (so-called emboss pattern) on an extruded product made of a hydraulic material as a main raw material. The present invention also relates to a method that allows the pattern to be changed freely and prevents repetition of the pattern and a decrease in productivity of an extruder.

は、内、外装材として広く用いられている。The main raw materials are cement, hydraulic gypsum, or a mixture of calcareous raw materials and silicic raw materials, and if necessary, reinforcing fibers, lightweight materials, hardening accelerators, etc. are added to the mixed raw materials, which are kneaded with water. Extruded products obtained by extrusion molding and curing in natural, steam or autoclave are widely used as interior and exterior materials.

性が低下する。In order to improve the aesthetic appearance of the extruded product, there is a method of creating irregularities on the inner periphery of the die and adding a corresponding pattern to the extruded product, but in this method, the pattern is only irregularities in the same direction as the extrusion direction. In order to change the pattern, it is necessary to remove the extruder and replace the nozzle each time, which reduces the productivity of the extruder.

ため押出機は停止−され生産性が低下する。Embossed patterns are also used to further improve the aesthetic appearance, but in a method in which a roll or endless sheet with a pattern engraved on the uncured molded body is rolled and rotated in synchrony with the uncured molded body, the roll or endless sheet is The pattern is repeated with each revolution, and changing the pattern requires replacing the roll or endless sheet, which causes the extruder to shut down and reduces productivity. Endless sheets can also be produced by introducing an endless sheet with a pattern carved into it into a die, pressing it against a substrate inside the die, extruding it and adding the pattern to the substrate at the same time, and peeling the endless sheet from the uncured molded product outside the die. The pattern is repeated every rotation of the extruder, and changing the pattern requires replacing the endless sheets, which causes the extruder to stop and reduce productivity.

ことを手段とするものである。In order to solve the above-mentioned problems, the present invention reciprocates the stamping rod in a direction perpendicular to the uncured molded body which is being extruded and formed from a base material mainly made of a hydraulic material, thereby pressing the tip of the stamping rod into the uncured body during extrusion molding. The method is to separate the molded product and form a concave pattern on the surface of the uncured molded product.

することにより自由に制御することができる。The base material, which is made by adding water and kneading a hydraulic substance as the main component, has plasticity that allows it to be formed into any cross-sectional shape with the die of an extruder. The tip of the stamping rod is press-fitted into the surface of the uncured molded object when it is pressed down in the orthogonal direction by the drive head of a piston, servo motor, etc., and when the stamping rod is then pulled back and removed from the uncured molded object, the uncured molded object is removed. A dent pattern is left on the surface. The depth of the concave pattern can be freely controlled by controlling the length of the stamping rod.
