The lift arm (17) is configured as a two-stage speed increasing mechanism and a pinion-rack mechanism for driving the two-stage speed increasing mechanism.
摘要:
A molded component retrieving apparatus and a molding machine with the molded component retrieving apparatus mounted thereon are disclosed. A first unit (3) of the molded component retrieving apparatus includes a base (10), first to third arms (12, 14, 16) and a first lift arm (17). A second unit (4) includes fourth to sixth arms (20, 22, 24) and a second lift arm (25). The second unit (4) is removably mounted on the third arm (16) through an intermediate base member (18). The rotary shafts (11, 13, 15, 19, 21, 23) of the arms are aligned in the same axial direction. A holding unit to hold and retrieve the molded component or the runner is arranged at the forward end of the first and second lift arms (17, 25). Even in the case where the molded component retrieving apparatus is mounted at the upper portion of the molding machine, each arm can pivot horizontally and therefore the machine height can be kept low, while the molding machine with the retrieving apparatus mounted thereon can be kept within the transverse limit of the molding machine. Also, even in the case where the drive sources are reduced in number and other arms are pivoted using a belt and a pulley, the third and sixth arms (16, 24) can be kept in position. As a result, the apparatus can be mounted on the molding machine even at a place having a low ceiling and the molding machine can be transported with the apparatus mounted thereon.

A cemented carbide comprises a binder phase consisting essentially of an iron family metal, a first hard phase consisting essentially of WC having a hexagonal crystal structure, and a second hard phase consisting essentially of one or more types of a compound of a metal or metals of group 4, 5 or 6 of the periodic table having an NaCl-type cubic crystal structure. The cemented carbide is formed by a surface region with a thickness of 2 to 50 μm consisting of the binder phase and the first hard phase, and an inner region present underneath the surface region consisting of the binder phase, the first hard phase and the second hard phase. A ratio of an average grain size of the first hard phase in the surface region to an average grain size of the first hard phase in the inner region is 1 or less, and a ratio of an area of the binder phase in the surface region to an area of the binder phase in the inner region is greater than 1.

An industrial robot comprises a column 1 fixed to an installation base BS, a first axis J1, which is a linear movement axis, a second axis J2 and a third axis J3, which are rotational axes, and a fourth axis J4 in the form of a driving axis (rotational axis) of a working tool. A food grade lubricating oil is used for the linear guide (2), ball screw (5), bearing (6), speed reducers (9, 19) and gears (10, 20, 30) of these axes. Oil seals (15, 25, 35) for sealing the food grade lubricating oil are made from a material which is harmless to human bodies, for example, a fluorine resin material, in consideration of their wear.
