TECHNICAL FIELD OF THE INVENTION
The present invention relates to a grooving method capable of quickly and satisfactorily grooving a press board surface.
[0002]
[Prior art]
The press board is a flat plate produced by laminating wet paper made of kraft pulp fiber or mixed fiber of kraft pulp and cotton, and pressing this. As described above, the press board is formed as a flat plate, and is currently used for various purposes. For example, it is used as a forming material for building materials, household furniture and boxes, and also as a functional member such as an insulating material for electric equipment. In particular, when used as a functional member such as an insulating material for electrical equipment, the press board can be used as it is, but the press board is a press board carta that is cut into small pieces of a certain size, and this is used as an insulating material. Can be used.
[0003]
Such a press board may need to be grooved on its surface. For example, in the case of building materials, household furniture and boxes, this is the case of an assembled member in which a groove is provided on the processed press board surface to form a joint, and several members are assembled at the joint. In addition, when used as a functional member such as an insulating material of electrical equipment, it is necessary to provide a groove on the press board surface in order to enhance performance such as electrical insulation and cooling.
[0004]
[Problems to be solved by the invention]
However, due to the property of the material that the press board is formed by pressing the pulp fiber as described above, when the groove is simply formed on the press board surface, compared with the case of the groove processing on the wood, the grooved portion is formed. In many cases, many burrs are generated, and the generated burrs cause insufficient groove processing. Furthermore, there is a drawback in that chamfering for deburring is specially required thereafter.
[0005]
In particular, when a press board is used as a functional member such as an insulating material of an electric device, it is known that burrs generated in a grooved portion may deteriorate performance such as insulating properties. In addition, when the press board carta, which is a small piece, is used as an insulating material, it is necessary to handle a large number of press board carta at a time from the viewpoint of groove machining efficiency.
[0006]
Conventionally, as a method of forming a groove on the press board carter surface, as shown in FIGS. 14 and 15, first, a plurality of press board carta pieces 31 are attached on the surface of one press board substrate 30. The sticking board 33 is obtained. In this case, the press board pieces 31 are separated from each other by a gap 31 of a groove to be formed. Next, the adhesive board 33 was cut in the order of the dimensions of the press board carta.
[0007]
That is, in the conventional method, as shown in FIG. 16, first, a strip-shaped cut piece 33a is obtained from the adhesive board 33 along the width a of the press board carta. Next, the cutting piece 33a is cut c along a sectioning line b matching the plane shape of the press board carta 34 to obtain a plurality of press board carters 34. In the obtained press board carta 34, a portion of the space 31 is a processing groove in order to avoid generation of burrs and the like at the time of groove processing.
[0008]
However, in the above-mentioned conventional grooving method, an operation of attaching the press board carta piece 31 and an operation of cutting the attachment board 33 in accordance with the planar shape of the press board carta 34 are required in advance, and a long time is required for machining. Since it is necessary, there are drawbacks in that the processing efficiency is poor and the economical minus is large. Also, when cutting the sticking board 33, burrs are generated, so a chamfering process for processing the burrs is required separately. This is also economically negative. Furthermore, with respect to the press board carta 34 subjected to the groove processing, the portion of the press board carta piece 31 stuck is easily peeled off, and when this press board carta 34 is used as a functional member such as an insulating material, the presence of the peeled piece is Also, there is a disadvantage that the function such as the insulating property of the press board carta is greatly impaired.
[0009]
The present invention is aimed to provide a groove processing method of the pressboard surface capable of grooving quickly and economically to a plurality of pressboard Carta used as a functional member such as insulation materials .
