JPS5877502A - Sealing device for capsule packed with metallic powder - Google Patents

Abstract

PURPOSE:To perform titled sealing with high working efficiency by holding vises for press contacting, vises for holding, cutters, etc. movably to parallel arms provided in upper and lower multiple stages between vertically movable frames on a freely movable carriage. CONSTITUTION:After metallic powder is packed in a capsule, the inside of the capsule is evacuated through a metallic pipe which serves also as an inserting pipe and an air releasing pipe. A carriage 12 and an oil hydraulic vise mechanism 20 for press contacting are moved forward with respect to the capsule packed with the metallic powder and completed of the evacuation to butt the stationary press holding piece 7b of the mechanism 20 to the side surface of said metallic pipe and the metallic pipe is brought into press contact with a movable press contacting piece 7a by using an oil hydraulic cylinder 24 for press contacting. Thereafter the mechanism 20 is released, and the press-contacted part of the metallic pipe is cut by using the holding vise mechanism 21 and cutter 22 of horizontal arms 18a, 18b. After the cutting, a stand 13 is moved upward by using oil hydraulic cylinders 15a, 15b for moving the stand upward and downward while the press-contacted part is held in press contact by the mechanism 21, and the cut surface is build-up welded by using a torch mechanism 23 for TIG welding.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to metal powder molding, in particular, filling metal powder into a metal capsule of a predetermined shape, evacuating the inside of the capsule, and then isotropically compressing it with a medium in a high-temperature, high-pressure atmosphere. After evacuation inside the capsule during molding, the capsule is
-] 1 concubine, it is related to automatic 'M elbow IJI + king device a for downstream of sealing.

Recently, hot isostatic press processing (hereinafter abbreviated as HIP processing) has been introduced as a forming technology for producing various high-density molded products using metal powders such as cemented carbide steel and high-grade steel, and ceramic powders. 1) Although attempts have been made to put it into practical use, normally in this HIP process, in order to solidify metal powder etc. using a HIP device, 111] Note 1, 4 is required as a pre-process. The powder is filled into a metal capsule of a predetermined shape through a metal powder insertion tube inserted into a part of the capsule, and immediately after filling, the same tube is inserted to remove the air inside the capsule. It is necessary to evacuate impure gases and seal them.

This process of evacuation and sealing is done by heating the exhaust pipe, forging the cutting blade after welding, and overlaying the cut part with welding. Therefore, the inside of the capsule is made airtight, but this method not only requires the lifting of heavy objects such as a hammer under the L1 high pressure conditions, but also requires a long time for the sealing process.
Not only the dye production environment conditions but also the working methods are lacking, and improvements are strongly desired.

In particular, most of the work under the above-mentioned environmental conditions is performed manually, and almost all the automation has been proposed up to 131 ri'. Automated operation is an important issue that will become more important as HIP treatment progresses in the future.

The present invention deals with such a situation and provides a novel apparatus capable of performing the sealing process with high working efficiency by eliminating the deterioration of the working environment and the conventional defects of long processing times. The purpose is to

The device of the present invention, which is suitable for such purpose, has a frame consisting of at least two opposing pillars which are erected on a movable trolley so as to be movable downward; The frame includes parallel arms arranged in at least two stages, upper and lower, with a set of two parallel arms facing each other installed in the horizontal direction perpendicular to the six pillars of the frame, and the parallel Place a pressure welding vise on the arm starting from the bottom.

Each mechanism, such as a holding vise, a cutting device, and a TIG welding torch, if necessary, is arranged, and each of these mechanisms is configured to be movable along the parallel arm.

Hereinafter, embodiments of the present invention will be described with further reference to the accompanying drawings.
