Abstract

PROBLEM TO BE SOLVED: To provide a pressure device capable of always uniformly pressurizing a pressed object even when the pressed object has variation in thickness. SOLUTION: When a lower part pressure disk 2 is elevated by a hydraulic cylinder 4, a pressed object A placed on the lower part pressure disk 2 is brought into press-contact with an upper part pressure disk 3, and the pressed object A is pressurized by each of the pressure disks 2 and 3. In this case, when the thickness of a part of the pressed object A is different from the other part, by the press-contact of the pressed object A with the upper part pressure disk 3, the lower part pressure disk 2 is brought into tilt following the variation in thickness of the pressed object A by a tilting mechanism 5, and then the pressed object A is uniformly pressurized.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressurizing device used for manufacturing various industrial products.

[0002]

2. Description of the Related Art Conventionally, as this kind of pressurizing device, as described in Japanese Utility Model Application Laid-Open No. 2-65498, for example, a lower pressurizing plate attached to a hydraulic cylinder and an upper surface of the lower pressurizing plate are opposed to each other. And an upper press platen arranged as
2. Description of the Related Art There has been known an apparatus in which a lower pressing plate on which a pressing target is placed is raised and the pressing target is pressed against an upper pressing plate to press the pressing target with each pressing plate.

[0003]

However, in the conventional pressurizing device, since each pressurizing plate is fixed so that the opposing surfaces are parallel to each other, when the thickness of the pressurized object varies, There is a problem that the object to be pressed cannot be pressed uniformly, which affects quality.

[0004] The present invention has been made in view of the above problems, and an object of the present invention is to always pressurize a pressurized object uniformly even when the thickness of the pressurized object varies. It is an object of the present invention to provide a pressurizing device capable of performing the following.

[0005]

To achieve the above object, according to the present invention, a plurality of pressure plates arranged opposite to each other are pressed in a direction approaching each other, so that each pressure plate is pressed. A pressurizing device for pressurizing the pressurizing object between the pressurizing device and the pressurizing device, further comprising tilting means for supporting the at least one pressurizing plate so as to be tiltable with respect to a surface facing the other pressing plate. Accordingly, when the thickness of the pressing target varies, when the pressing target is pressed against the pressing plate, at least a part of the pressing plate tilts to follow the variation in the thickness of the pressing target. Thus, the object to be pressed is uniformly pressed.

According to a second aspect of the present invention, there is provided the pressurizing device according to the first aspect, further comprising a holding means for elastically holding a pressure plate, which is tiltably supported by the support means, in a predetermined posture. Thereby, in addition to the effect of the first aspect, the pressure plate is kept in a predetermined posture except when the pressure is applied.

[0007]

1 to 3 show one embodiment of the present invention. FIGS. 1 and 2 are front views of a pressurizing device, and FIG. 3 is an explanatory view of its operation.

This pressurizing device includes a frame 1 forming a main body of the device, a lower pressurizing plate 2 on which an object to be pressurized is mounted, an upper pressurizing plate 3 disposed above the lower pressurizing plate 2, and a lower pressurizing plate. It comprises a hydraulic cylinder 4 for raising and lowering the platen 2, a tilting mechanism 5 for tiltably supporting the lower pressure platen 1, and a holding mechanism 6 for elastically holding the lower pressure platen 1.

The frame 1 has substrates 1a and 1b vertically spaced from each other, and the upper substrate 1a is supported by the lower substrate 1b via a plurality of columns 1c.

The lower pressure plate 2 has a flat surface facing the upper pressure plate 3 and is fixed to a lifting plate 2a which is raised and lowered by a hydraulic cylinder 4.

The upper pressing plate 3 has a flat surface facing the lower pressing plate 2, and is fixed to the substrate 1 a above the frame 1.

The hydraulic cylinder 4 is fixed to the substrate 1b below the frame 1, and has its rod 4a penetrating above the substrate 1b.

The tilting mechanism 5 includes a rod 4 of the hydraulic cylinder 4.
a, a slide substrate 5b fixed to the upper surface of the substrate 5a, and a slide plate 5c fixed to the lower surface of the elevating plate 2a. The slide plate 5c is slidable on the slide substrate 5b. Supported. That is, the slide substrate 5b and the slide plate 5c have curved surfaces formed with the same curvature in contact with each other, and the slide plate 5c slides along this curved surface, whereby the lower pressure plate 2 is inclined with respect to the horizontal posture. It has become.

The holding mechanism 6 comprises a plurality of shafts 6a slidably penetrating the substrate 5a of the tilting mechanism 5 in a vertical direction, and a spring 6b for urging each shaft 6a downward. Are connected to the lower surface of the lifting plate 2a, respectively. That is, the lower surface of the elevating plate 2a is urged downward by the springs 6b on the shafts 6a arranged with the slide plate 5c therebetween, and is elastically held in a substantially horizontal posture in a natural state. I have.

In the pressurizing apparatus constructed as described above, when the lower pressurizing plate 2 is lifted by the hydraulic cylinder 4, the pressurized object A placed on the lower pressurizing plate 2 is pressed against the upper pressurizing plate 3. Then, the pressing target A is pressed by the pressing plates 2 and 3. At this time, as shown in FIG.
When the thickness A1 of the part A is different from the thickness H2 of the other part, when the pressing object A is pressed against the upper pressing plate 3,
As shown in (b), the lower pressing plate 2 is tilted by the tilting mechanism 5 to follow the thickness variation of the pressing target A, and the pressing target A is uniformly pressed.

As described above, according to the pressurizing device of the present embodiment, one of the pressurizing plates 2 is supported to be tiltable by the tilting mechanism 5, so that the thickness of the pressurized object A varies. Even when the lower pressing plate 2 is tilted, the pressing target A can always be pressed uniformly, and for example, the production of a multilayer board can be performed.
The quality can be improved in the manufacture of a product requiring a pressure treatment. In addition, since the lower pressing plate 2 can be held in a substantially horizontal position by the holding mechanism 6 except during pressing, the operation of the lower pressing plate 2 can be stabilized.

In the above-described embodiment, the pressing device having a pair of upper and lower pressing plates 2 and 3 is shown. However, the present invention is also applicable to a pressing device having another pressing plate between the upper and lower pressing plates. can do.

[0018]

As described above, according to the pressing device of the first aspect, even if the thickness of the object to be pressed varies.
Since the object to be pressed can always be uniformly pressed, the quality can be improved in the production of a product requiring a pressure treatment, such as the production of a multilayer board.

According to the pressure device of the second aspect, in addition to the effect of the first aspect, the pressure plate can be held in a predetermined posture other than when the pressure is applied, so that the operation of the pressure plate is stabilized. be able to.
