Abstract

PURPOSE:To make it possible to embed a reinforcing bar even in a molding which is to be molded flat, by a method wherein molding nozzles for extrusion molding a board shaped body are separated up and down, a reinforcing bar feeding guide which is disposed in the space of the nozzles is supported movably reciprocally in the normal direction to the extrusion direction of the inoganic material. CONSTITUTION:In molding nozzles 3A, 3B discharge ports 4A, 4B are separated up and down from each other, reinforcing bar feeding guides 5, 5 are supported movably reciprocally in the normal direction Y to the extrusion direction X. Homogeneously kneaded inorganic material P is extruded from an extruder 2, and extruded from the molding nozzle 3A, 3B into up and down two layers. In this case, reinforcing bars 6, 6 are fed from the space S of the molding nozzles 3A, 3B in the extrusion direction, after the extrusion, molding bodies P1, P2 are laminated with the reinforcing bars 6, 6 by sandwiching the bars, then integrated with them by a press roll 8. In this case, the reinforcing bar 6, 6 are fed zigzag in the width direction (arrow Y) of the molding bodies P1, P2 by guides 5, 5 which reciprocally move in a speed synchronously with the extrusion rate.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an extrusion molding apparatus for inorganic products, and more particularly to an extrusion molding apparatus for inorganic products in which reinforcing bars are embedded.

[Conventional technology]

Conventionally, it has been widely used to extrude plate-shaped molded products using hydraulic materials such as cement.
It is also widely used as a useful material for molds.

By the way, since the bending strength of the above-mentioned inorganic building materials is generally weaker than the compressive strength, reinforcing bars are continuously embedded in the molded product, but in extrusion molding,
It is necessary to introduce reinforcing bars into the molding die, and for this reason,
The structure of the die becomes very complicated, and the extrusion resistance also increases, and various technical problems arise in solving these problems.

In order to solve these problems, for example, as disclosed in Japanese Patent Application Laid-open No. 62-39203, cement plates are extruded into two layers, upper and lower, at the tip of an extruder, and the extrusion molded body is It has been proposed that the reinforcing bars be removed vertically apart from each other, reinforcing bars are supplied from the created space in the pulling direction, the extrusion molded bodies are stacked again, and the reinforcing bars are sandwiched in a sandwich shape.

[Problems with conventional technology]

By the way, in the case of the above means, there is no need to provide a reinforcing bar supply device in the molding die, and the above problem can be solved; however,
Immediately after extrusion molding, the extruded molded product, which is extremely susceptible to deformation, is separated vertically and taken off, so there are complicated problems in setting the take-up speed and path of the molded product between the gaps, and sheet-shaped reinforcing bars are also supplied. In this case, the reinforcing bar supply and guide means is also large-sized, and there are various problems that need to be solved in practice, such as how to set the relationship with the vertical separation distance.

[Problems solved by the invention]

In view of the above-mentioned problems, this invention was developed by extrusion molding of a non-metallic product, which eliminates space problems even when the molded body is formed into a flat plate shape, and in which reinforcing bars can be continuously embedded. This was done for the purpose of providing equipment.

[Technology for Solving Problem C] That is, in the extrusion molding apparatus for inorganic products of the present invention, a molding die for extruding a plate-like body in two or more layers, upper and lower, is provided at the tip of the extrusion apparatus for inorganic raw materials, and the extrusion molding apparatus for inorganic products of the present invention The discharge ports are vertically separated from each other, and a reinforcing bar supply guide is disposed in the space between the nozzles, and the reinforcing bar supply guide is perpendicular to the extrusion direction of the inorganic raw material. It is characterized by being supported so that it can reciprocate in the direction.

〔Example〕

Next, the present invention will be explained in detail.

FIG. 1 is a plan view of an embodiment of the invention, FIG. 2 is a side view of the embodiment, and FIG. 3 is a side view of another embodiment.

The extrusion-molded bag Tt1 for inorganic products of the present invention has at least two upper and lower layers of plate-shaped bodies -PI,
Molding nozzles 3A and 3B for extrusion molding P2 are provided, and discharge ports 4A and 4B of these molding nozzles 3A and 3B are vertically separated from each other as shown in FIG. A reinforcing bar supply guide 5.5 is disposed in the space S, and this guide 5.5 is supported so as to be movable back and forth in a direction (arrow Y) perpendicular to the extrusion direction (arrow X). has been done.

Note that 7 in the figure indicates a hydraulic device that drives the reinforcing bar supply guide 5.5, and the reinforcing bars 6, 6 are continuously supplied from a bobbin case placed outside the device, although not shown.

In the above embodiment, the extrusion molding die 3A, 3B has two layers, upper and lower, but it is also possible to have three or more layers as shown in FIG.

The device shown in FIG. 3 has the same configuration as the devices shown in FIGS. 1 and 2, except that the base has three layers, so only the same numbers are used to describe the details. Explanation will be omitted.

[Effect]

Next, the present invention will be explained in detail.

The uniformly kneaded inorganic raw material P is extruded from the extrusion device 2, and then extruded into upper and lower layers from the molding nozzles 3A and 3B.

At this time, the reinforcing bars 6.
6 is fed in the extrusion direction, and after extrusion, the molded bodies P+ and Pt are laminated with reinforcing bars 6.6 sandwiched between them, and are further integrated by press rolls 8.

In this case, the reinforcing bars 6.6 are moved by guides 5.5 that reciprocate at a speed synchronized with the extrusion speed to
O It is supplied in a zigzag shape in the width direction (arrow Y).

〔effect〕

As explained above, this invention extrudes the extruded raw material into two or more layers from one extruder, and at that time, the space between the nozzles is used to supply reinforcing bars, so that the extruded product is not extruded. It can be laminated immediately, and there is no need to apply unreasonable force to the molded product.It can be easily molded, and the reinforcing bars are linear, so that the molded product becomes woven during supply. Since it is fed in the form of a sheet, the feeding device can be small, and it has various effects such as being easy to implement.
