Embodiment Construction

[0024] Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings. figure 1 It is a schematic configuration diagram of the isotropic pressurizing device 10 according to the embodiment of the present invention. also, figure 2 is a schematic plan view of the isotropic pressurizing device 10 .

[0025] This isotropic pressurizing device 10 is a device that isotropically pressurizes and heats a workpiece 100 held by a housing 14 with warm water to form it.

[0026] image 3 is a diagram showing an example of the workpiece 100 . In this embodiment, a multilayer body 102 for a multilayer capacitor and the like are used as the workpiece 100 . The laminated body 102 is laminated with ceramic green sheets on which conductors of a predetermined shape are printed. Since the laminated body 102 is softened by heating, it cannot maintain its shape as a single body, and thus is placed on the plate 104 in advance. The plate ...

Abstract

When a basket (14) that holds a workpiece is lifted out of a pressure vessel (12), raising is first carried out inclusive of a cover body (16) in a state of connection to the cover body (16) from an accommodated position in which the entirety thereof is accommodated in the pressure vessel (12) to an attachment / detachment position in which the upper edge of the basket (14) protrudes from the pressure vessel. In the attachment / detachment position, the connection between the cover body (16) and the basket (14) is released, and the cover body (16) is moved to a withdrawn position in a parallel direction. In that state, the basket (14) is lifted from the pressure vessel (12) to a lifted position in which the same is completely lifted. When the basket (14) is being accommodated in the pressure vessel (12), a reverse procedure is carried out.

Description

technical field [0001] The present invention relates to an isotropic pressurizing device, which accommodates a holding container for holding a workpiece in a pressure container whose upper end opening is covered by a cover, and the liquid injected into the pressure container acts on the pressure container. The workpiece is pressed isotropically. Background technique [0002] Conventionally, there is known an isotropic pressurizing device in which a pressurized object is accommodated in a pressure vessel, a liquid is supplied to the pressure vessel, sealed, and the pressurized object is pressurized by the liquid to form it. Such an isotropic pressurization device can be used, for example, for forming laminated electronic components such as laminated ceramic capacitors and laminated ceramic inductors. Multilayer capacitors are laminated by laminating and pressing ceramic green sheets printed with conductors of a predetermined shape, while heating to soften and bond the binder...
