Disclosed are a mould system and a clamping tong for securing a mould item part in a mould of a mould system. The clamping tong comprises: a primary tong segment comprising a primary clamping surface for applying clamping pressure on a clamping portion of a mould item part; a secondary tong segment coupled to the primary tong segment and comprising a secondary clamping surface for applying clamping pressure on a clamping portion of the mould. The clamping tong being configured to change between a clamping state and a release state, wherein the distance between the primary clamping surface and the secondary clamping surface in the clamping state is shorter than the distance between the primary clamping surface and the secondary clamping surface in the release state.

A clamping plier facilitating cutting includes two heads and two handles. One of the two heads has a blade in at least one position, and the other one of the two heads has a blunt cut at a corresponding position. The two handles are respectively and integrally connected with the two heads in one-to-one correspondence, and the two heads or the two handles are rotatably connected together, so that the two heads are opened or closed by operating the two handles. When the two heads are closed, a blade of one of the two heads is attached to a plane of the blunt cut of the other one of the two heads to cut the cable. The blade of one of the two heads is easier to fit closely with the plane of the blunt cut of the other one of the two heads.

A one-way oil-way driven expansion and retraction movement tool includes a hydraulic driving structure, two long arm rods and two connecting rods, wherein, the hydraulic driving structure has a cylinder barrel, a plunger and a shaft rod, the two arm rods are opposite each other and are opposite the two sides of the shaft rod in the lateral direction. One end of each arm rod is respectively pivoted on the cylinder barrel, and the other end of each arm rod is respectively used for arranging a working piece, so that each working piece can move toward or away from each other to execute corresponding work. The connecting rods are respectively pivoted with each of the arm rods and with the connecting part, so that, through the connecting rods, the shaft rod can pull the arm rods to move away from each other or toward each other.

An integrated power clamp motor system includes a housing with one or more stator stages coupled to the inner surface. Each of the stator stages has a winding and a stator core with a plurality of stator teeth circumferentially distributed about a longitudinal axis, at an inner diameter of the stator core. A rotor is disposed about the longitudinal axis, inside the stator core, with a plurality of magnetic poles circumferentially distributed along an outer surface, adjacent the stator teeth. A power clamp assembly is coupled to the rotor via one or more of a screw assembly, a thrust rod, and a transmission, and operational between first and second positions responsive to rotation of the rotor.

A mechanical device for grasping an object includes a receiver having a distal end shaft with an internal bore, the internal bore defining a recessed track. The recessed track defines a curvilinear path having two sets of resting peaks, each set of resting peaks being at a different height relative to a centerline of the curvilinear path. An actuator is slidably engaged with the receiver and includes a central shaft and an activator disposed at a distal end portion of the central shaft. A rotatable sleeve is disposed within the internal bore of the receiver and is coupled to the actuator. The rotatable sleeve has opposed protrusions, the opposed protrusions being disposed within the recessed track of the receiver. A pilot is secured to a distal end portion of the receiver and a grasping device is mounted to the pilot and coupled to the activator.

A power clamp includes a body. A piston assembly is coupled with the body. The piston assembly includes an actuation mechanism and a movable piston rod. A linkage is housed in the body. The linkage is movably coupled with the piston rod. A plunger is movably coupled with the linkage. A clamp hook is coupled with the plunger for clamping a workpiece. The linkage moves the clamp hook between a release and clamping position.

A fulcrum opening/closing type air chuck includes porous bodies that are attached to a body and come into contact with fingers, and purge air passes through the porous bodies and is discharged to the outside.

The apparatus (1) for clamping workpieces on machine tools comprises: a basic frame (2) fixable to a machine tool (M) for machining a workpiece (P); a clamping unit (3); a hydraulic actuator (22, 23) comprising a first chamber (26) which can be supplied with a first pressurized hydraulic fluid and is connectable to a first sensing device (27) for sensing the pressure of the first hydraulic fluid; a sensing channel (15) which can be supplied with pressurized air and which is connectable to a sensing sensor (16) for sensing the pressure of the air;
wherein the first sensing device (27) and the sensing sensor (16) are connectable to a control system adapted to authorize the machining of the workpiece (P) when the pressure of the first hydraulic fluid and the pressure of the air are simultaneously higher than their respective threshold values.

A closing device for a mold group with two half-molds extends along a main axis and has a device body mountable to one of the two half-molds, and a closing group having a closing element rotatable about a rotation axis between a closing position, in which the two half-molds are lockable and an opening position, in which the two half-molds are releasable. A movement group housed in the device body and engaged with the closing group to rotationally move the closing element has a stem movable along the main axis and transmission members for transforming linear motion of the stem into rotatory motion of the closing element. A command group has a command plate engaged with one command end of the stem and a metal sealing bellows engaged with the command plate. A position of the metal sealing bellows corresponds to an axial position of the command plate and of the stem.

An output part is provided to the left end of a clamp arm that is supported by a housing so as to be slidable in the vertical direction. At the left end of the housing, a first hole for spring fitting opens obliquely upward towards the output part. A through hole that links the upper surface and the lower surface of the clamp arm is disposed obliquely upward at a left-leaning part of the clamp arm. A second hole for spring fitting and a female screw hole are formed, in that order, upwards in the through hole. A return spring that is installed through the first hole and the second hole impels the output part upwards. A push bolt that is screwed into the female screw hole rom above compresses the return spring.
