摘要:
A low-pressure die-casting apparatus comprising at least one flowing furnace (10) with which at least one handling unit (12) cooperates, the handling unit being selectively connectable to a respective die (14). The at least one handling unit (12) is associated with a guide (13) for horizontal translatory motion between a casting position, which lies above the at least one furnace, and a discharge position. The at least one furnace (10) can move vertically in order to couple and uncouple with respect to the corresponding die (14) connected to the at least one handling unit (12).
摘要:
A meter for liquids comprising a tubular body (11), internally provided with a rotor (14) whereto a magnet (15) is keyed, and with ends which can be engaged in pipes in which there flows a liquid whose flow-rate is to be detected together with the volume, detected as a function of the flow-rate; a readout device (19) being associated with the tubular body (11) and being arranged inside a "dry" chamber (17); the magnet being operatively connected to a pulse counter (23) which is located inside the "dry" chamber (17) and is connected to a display.
摘要:
A low-pressure die-casting apparatus, of the type comprising: - at least one furnace (11, 111) adapted to produce the molten mass to be cast into the die (12), - at least one station (18, 118) for unloading the cast part and/or loading at least one core to be inserted in the die (12), - at least one die supporting fixture (14, 114), which is associated with means for translational motion on a guide (13, 113) proximate to which the at least one furnace (11, 111) and a station (18, 118) for unloading the part and/or loading at least one core are arranged, - means (31) for preparing for the step for filling the die (12), and comprising rotation means (30) for the die supporting fixture (14, 114) which are suitable to arrange the fixture (14, 114) so that the die (12) is located on one chosen side of the guide (13, 113) for interaction with preset apparatus components.
摘要:
A gravity casting apparatus with tilting die, comprising a die-casting machine (11) with which a corresponding die (12) is associated, elements (13) for feeding molten mass (18) in a casting inlet region (14) of the die (12), and elements (20) for cooling the die (12) before the casting step, which are associated with elements for distributing release agent inside at least one impression provided inside the die (12); the die is tiltable about at least one horizontal tilting axis which passes through the center of the inlet region of the die and said elements for feeding molten mass are constituted by at least one pressurized dosing furnace.

摘要:
A spindle assembly for chip-forming machine tools, such as transfer machining systems or machining centers, comprising a module (19) with a movable platform with parallel kinematics (a module such as a Stewart platform) on which a spindle (20) is arranged. Means (29) for translational motion along two mutually perpendicular directions (x, y) are associated with the module of the Stewart platform type and allow a translational motion of the module of the Stewart platform type (19) with respect to the base frame (17) of the machine tool, thus increasing the volume on which the tool fixed to the spindle (20) can work.
