摘要:
A transfer press machine which can be easily handled for precise and prompt interference checks. The transfer press machine is provided with an interference check device including data component storage means for storing press side data components and transfer side data components, as turned three-dimensional data, in such a state that they are expanded and arranged in a virtual space with the same relative position relation as that of the case in a real space, virtual press action control means for causing the press side data components to perform the virtual press actions in the virtual space in accordance with press motions, virtual transfer action control means for causing the transfer side data components to perform the virtual transfer actions in the virtual space in accordance with transfer motions, virtual synchronous timing information generating/outputting means for generating/outputting virtual synchronous timing information, and virtual interference occurrence discriminating means for discriminating whether or not an interference occurs between the press side data components and the transfer side data components in the procedure of the virtual transfer press cycle.

A first die is filled with a mixed powder including a lubricant. A first pressure is applied to the mixed powder to form a mixed powder intermediate compressed body having a true density ratio of 85 to 96%, provided that the maximum density of the mixed powder intermediate compressed body that can be molded by applying the first pressure is 100%. The mixed powder intermediate compressed body is heated to the melting point of the lubricant powder. The mixed powder intermediate compressed body is placed in a second die that is pre-heated to the melting point. A second pressure is applied to the mixed powder intermediate compressed body in the second die to form a high-density mixed powder final compressed body.

A first die (21D) is filled with a mixed powder (100) that is a mixture of a basic metal powder and a low-melting-point lubricant powder. A first pressure is applied to the mixed powder to form a mixed powder intermediate compressed body (110) having a protrusion (110A) that protrudes in the pressing direction as compared with the configuration of a mixed powder final compressed body (120). The mixed powder intermediate compressed body (110) is heated to the melting point of the lubricant powder. The heated mixed powder intermediate compressed body (110) is placed in a second die (41D). A second pressure is applied to the mixed powder intermediate compressed body (110) to press-mold the mixed powder intermediate compressed body (110) while crushing the protrusion (110A) in the pressing direction to form the high-density mixed powder final compressed body (120) having high density and the desired configuration.
摘要:
A mixed powder (100) placed in a container cavity (24) is transferred to the cavity of a first die (31). A first pressure is applied to the mixed powder (100) in the first die (31) to form an intermediate green compact (110). The first die (31) and the intermediate green compact (110) are heated to heat the intermediate green compact (110) to the melting point of a lubricant. The heated intermediate green compact (110) is transferred to the cavity of a second die (61), and a second pressure is applied to the intermediate green compact (110) to form a high-density final green compact.
