Problems solved by technology

[0007] However, in the case of the open type method, there is a disadvantage that the outer surface of the stamper deteriorates due to oxidation, resulting in unstable temperature measurement
However, when, for example, high-frequency induction heating is used as the heating method, high-frequency waves are superimposed on the thermocouple, making it difficult to use a sheathed thermocouple

[0030] (Sintering Machine)

[0031] figure 1 shows the sectional configuration of the sintering machine according to the first embodiment of the present invention, and figure 2 express figure 1 The top plan configuration of the sintering machine shown. This sintering machine 1 is a uniaxial hot press machine, which includes: a mold 20 for accommodating a processing object 10 (that is, a powder to be sintered); The processing object 10 applies pressure; and the heating part 40 is used to heat the processing object 10 in the mold 20 . The processing object 10 is, for example, powder of a raw material of a sputtering target of a ceramic material, or its calcined material (sintered body).

[0032] The mold 20 has, for example, an insert mold (inner mold) 21 for defining the planar shape of the processed object 10 in a press mold (outer mold) 22 . The die 22 is, for example, a cylindrical member and serves as an isobaric vessel so that the pressure applied by the punch 30 is ...

[0089] Figure 9 A sectional configuration of a sintering machine 1A according to a second embodiment of the present invention is shown. When the processing object 10 is accommodated in the mold 20, the sintering machine 1A has the same configuration as the first The same structure, operation and advantageous effect in the embodiment. Therefore, repeated descriptions of the same constituent elements will not be repeated as appropriate.

[0090] As described above, when the processing object 10 is accommodated in the mold 20 , the hole 23 is provided at a position offset from the accommodation position of the processing object 10 in the height direction (z-axis direction) of the mold 20 . In other words, the hole 23 is provided so as to prevent it from being located on the extension line in the diameter direction of the accommodation position of the processing object 10 . This is because the results of the stress simulation show that the stress applied to the insert mold 21 ...

Abstract

The present invention provides a sintering machine and a method of manufacturing sintered body. The sintering machine includes: a die configured to accommodate a processing object, and having a hole that extends from an outer side surface of the die toward inside of the die; a pressurizing member configured to apply a pressure on the processing object in the die; and a heating section configured to heat the processing object in the die. The sintering machine and the method of manufacturing sintered body enable the influence of the quality change of the outer surface of the die to be reduced, thereby realizing a stable temperature measurement.

Description

[0001] Cross References to Related Applications [0002] The present invention encompasses subject matter related to that disclosed in Japanese Priority Patent Application JP2011-278267 filed with Japan Patent Office on December 20, 2011, the entire contents of which are incorporated by reference into this article. technical field [0003] The present invention relates to a sintering machine that places a processing object in a mold to sinter the processing object by pressing and heating (hot pressing) and a method of manufacturing a sintered body using the sintering machine. Background technique [0004] A heat press (pressurized heating furnace) places a work object in a die (press die or mold) to heat the work object while applying pressure to the work object using a pressing member (punch). Methods for heat presses are classified into several types, and as one of the classified methods, there are a hermetic type (closed type) method and an open type method which is in a...
