Description

  The present invention relates to an apparatus for producing an extruded corner material with a concavo-convex pattern. More specifically, the corner material such as an outer wall material and a partition wall is extruded using a hydraulic material such as cement, and at the same time, the surface of the corner material is arbitrarily selected. The concavo-convex pattern is attached.

  When connecting the outer wall material etc. which consist of a shaping | molding board from a different direction, the corner material previously integrally formed by the angle may be used for the corner part. This corner material can be manufactured by mold forming or extrusion molding. In the case of mold forming, a hydraulic material is poured into a mold having a predetermined shape, and after the hydraulic material is cured, the molded product is removed to obtain a corner material. In the case of extrusion molding, a hydraulic material is extruded from a die having a predetermined extrusion opening shape, and the molded product is cured to obtain a corner material. In the corner material thus obtained, when the left and right outer wall materials are patterned, the same patterning is also required on the surface of the corner material. In the case of a corner material formed by mold forming, by providing a similar concavo-convex pattern on the inner surface of the mold, the concavo-convex pattern can be applied to the surface of the molded product. On the other hand, in the case of a corner material by extrusion molding, it was the limit to apply a stripe pattern in the extrusion direction from the molding principle.

  However, in the method of forming the corner material using the above-described formwork, it is necessary to have the formwork as many as the number of lots that require primary hardening, which increases the formwork cost and requires the formwork storage space. It was. In addition, in the case of a mold-molded product, unlike the extrusion-molded product, since the raw material cannot be pressure-molded, the molding surface becomes rough, and a good smooth surface such as the extrusion-molded product cannot be obtained. Furthermore, in the case of an extrusion molded product, a molded product having a hollow portion can be easily formed by disposing a center ball at the extrusion port. However, in the case of a mold-molded product, it is difficult to form the hollow portion. There was a defect limited to the molded product. On the other hand, in the corner material by extrusion molding, a method of pressing the pair of embossed belts and the like on which the concavo-convex pattern has been formed on the pair of surfaces of the corner material immediately after extrusion and transferring the concavo-convex pattern is also conceivable. In this case, as shown in FIG. 5, an escape portion for avoiding interference must be provided between the embossed belts 1, 1, so that an R portion 3 that cannot be patterned at the corner is generated, There is also a problem that burrs 7 occur between the R portion 3 and the textured portion 5. Further, when patterning is performed by pressing the embossed belts 1 and 1 against such a pair, it is considered that the left and right embossed belts 1 and 1 are difficult to synchronize and the left and right patterns are displaced. Further, when the embossed belts 1 and 1 are used, it is impossible to pattern the corner corner material or the R (curved surface) corner material. The present invention has been made in view of the above situation, and is not limited to the stripe pattern in the extrusion direction, and can be patterned in any direction, and can obtain a good smooth surface of the extruded product. The object of the present invention is to provide an apparatus for producing an extruded corner material with a concavo-convex pattern that can be patterned on the entire surface regardless of the corner material or the R corner material.

  An apparatus for producing an extruded corner material with a concavo-convex pattern according to the present invention includes a receiving member having a linear receiving groove in which an arbitrary concavo-convex pattern is formed on an inner wall surface, and a center ball for forming a hollow portion in the extruded corner material. An extrusion port disposed is disposed in the receiving groove, a base for extruding an uncured extruded corner material from the extrusion port in close contact with the inner wall surface, and the receiving member in synchronization with an extrusion speed of the extruded corner material Conveying means in the longitudinal direction of the receiving groove, and the base is open below the center part of the extrusion port, and the extruded corner material of the receiving member is opened at the open part. It is characterized in that it is extruded in close contact with the inner wall surface.

  According to the manufacturing apparatus for an extruded corner material with a concavo-convex pattern according to the present invention, a receiving groove formed with a concavo-convex pattern is formed on a receiving member, a base for extruding the corner material is provided in the receiving groove, and synchronized with the corner material extrusion speed. Since the conveying means for conveying the receiving member is provided, the uncured corner material pushed out from the base can be received by the receiving member without relative movement, and the corner material received by the receiving member can have any receiving groove. The uneven pattern can be transferred.

  Hereinafter, preferred embodiments of a method for producing an extruded corner material with an uneven pattern according to the present invention and an apparatus therefor will be described in detail with reference to the drawings.

  The receiving member 13 is constituted by a receiving iron plate 19 made of, for example, an equilateral mountain-shaped steel material, and a resin plate 21 with an embossed die of the same equilateral mountain placed on the corner of the receiving iron plate 19. The resin plate 21 uses the entrance corner side as a V-shaped receiving groove 23. On the inner wall surface of the receiving groove 23, an arbitrary embossed pattern (uneven pattern) made of an uneven surface is formed. The resin plate 21 is placed on the receiving iron plate 19 in a state where relative sliding with the receiving iron plate 19 is restricted.
