Abstract

PURPOSE:To perform cutting in an end face finish state simultaneously with cutting of an uncured plate. CONSTITUTION:A cutting device for an uncured plate is provided with a cutting edge surface 3A crossing obliquely of the direction of the thickness of an uncured plate 2, molded by using a cement mixture, or crossing the plate in a manner to form the shape of a curved surface. The cutting device comprises a cutting edge body 3 movable vertically based on the uncured plate 2, and an ultrasonic exciting device 4 fixed to the cutting edge body 3. The uncured plate is cut in a profile end face by utilizing the thixotropy properties of a material to be cut produced through vibration generated by the ultrasonic exciting device 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for cutting uncured plate material, and more particularly to a device for cutting an uncured plate material formed by a cement compound into a slope or a curved surface.

[0002]

2. Description of the Related Art As a continuous production method of a thick inorganic plate material using a cement mixture, a wet cement material is formed into a band shape, such as an extrusion molding method or a roll pallet method,
There is known a production method in which a product is obtained by cutting this into predetermined lengths and curing and curing. In these manufacturing methods, as a device for cutting the uncured product into predetermined lengths, the cutting blade is supported by a support frame that can be moved synchronously according to the moving speed of the product, and the cutting blade is moved up and down during the synchronous movement to move the product A cutting device is used.

[0003]

[Problems of the prior art] By the way, a thick inorganic plate material,
Particularly in a roof tile, the end surface P thereof may be cut into a slope or a curved surface as shown in FIG. When such an end surface finish is performed, conventionally, an uncured molded product is cut with a guillotine blade for each predetermined length and roughly cut into each product unit shape, and then once cured and cured, the end surface is finished by a cutting process. However, as a result of the increase in the number of processing steps, there is a drawback that the manufacturing process becomes troublesome and the product cost rises.

[0004]

SUMMARY OF THE INVENTION In view of the above problems, the present invention has been made with the object of providing a novel cutting device capable of simultaneously cutting an uncured plate material into an end face finished state. .

[0005]

That is, the uncured plate material cutting device of the present invention is a cutting device for cutting an uncured plate material 2 formed by a cement mixture, and is perpendicular to the uncured plate material 2. The cutting blade 3 that is movable in the vertical direction is thick, and the blade surface of the tip of the thick cutting blade is an obtuse-angled blade surface that diagonally crosses the thickness direction of the uncured plate material 2. The ultrasonic vibration generator 4 is fixed to the main body 3.

Embodiments of the present invention will be described below. FIG. 1 is a side view of an embodiment of the present invention.

In the uncured plate material cutting device 1 of the present invention, the cutting blade 3 which is vertically movable in the vertical direction with respect to the uncured plate material 2 has a thick wall, and the blade surface at the tip of the thick wall cutting blade 3 is provided. 3A is an obtuse-angled blade surface 3A diagonally crossing the thickness direction of the uncured plate material 2
The ultrasonic exciter 4 is fixed to the cutting blade body 3.

In this embodiment, the obtuse shape of the blade surface 3A means a shape along the shape of the product end surface P, and when the shape of the other product end surface P of a mere slope is a convex curved surface,
As shown in the drawing, the blade surface 3A has a concave shape matching it, and when the end surface P is provided with an uneven pattern, the blade surface 3A
Those having such an uneven surface are used.

The vibrating device 4 is a magnetostrictive vibrating device, and is rigidly fixed to the cutting blade body 3 to directly transmit the vibration to the cutting blade body 3. In the above embodiment, in order to increase the cutting efficiency of the cutting blade main body 3, it is possible to support a plurality of cutting blade main bodies 3 on the base frame 3B as shown in the drawing so that the cutting process can be performed at the same time. In the figure, 5 ... 5
Indicates a product receiving pallet used according to the manufacturing method.

[0010]

When the uncured plate material cutting device 1 according to the present invention cuts the uncured plate material 2, the oscillating device 4 is driven to apply a vibration of about 50 kc to 80 kc to the cutting blade body 3 for cutting.
The thixotropy of the uncured plate material is exhibited by this vibration, and despite having the blade surface 3A that is an obtuse angled or curved obtuse shape, adhesion of the material to the blade surface 3A is prevented and the shape along the blade surface 3A is prevented. Be disconnected. Therefore, if the uncured molded product cut in this way is cured by curing, it can be commercialized as it is without requiring a cutting step or the like.

[0011]

As described above, according to the cutting apparatus of the present invention, it is possible to cut a strip-shaped product which is continuously supplied into a deformed end face shape, so that the subsequent processing steps such as cutting are unnecessary. Therefore, the manufacturing of these cement products is labor-saving.
