Title:
METHOD AND APPARATUS FOR PRODUCING MULTIPLE SHRINK-FITTING MEMBERS
Document Type and Number:
Japanese Patent JP2023140155
Kind Code:
A
Abstract:
To provide a method and apparatus for producing a shrink-fitting member that can simultaneously produce a plurality of shrink-fitting members.SOLUTION: Provided is a method of producing a plurality of shrink-fitting members in which method columnar ceramic bodies 20 are arranged inside a plurality of metal tubes 10 and shrink-fitted simultaneously. The producing method includes: a metal tube arrangement step in which first end 11 sides of the metal tubes 10 are placed so as to cover each of the plurality of protruding jigs 50 installed at a bottom 110 of the heating furnace 100; a columnar ceramic body placement step in which a columnar ceramic body 20 is placed on each of second end 12 sides of the plurality of metal tubes 10; and a shrink-fitting step in which a heating furnace 100 is heated to a temperature at which the metal tubes 10 can expand in diameter, and the columnar ceramic bodies 20 are moved over the protruding jigs 50.SELECTED DRAWING: Figure 5
