A dual pre-stacking system of steel plates for a single cutting line and a stacking method therefor. The dual pre-stacking system comprises: a cooling bed inspection stand, a crop shear with a cut-to-length function, a bilateral shear, 1# inkjet printer, a front pre-stacker, a cut-to-length shear, a length and thickness gauge, 2# inkjet printer, surface check/size inspection and fitting, and a rear pre-stacker arranged in order along the roller. The dual pre-stacking system and the stacking method therefor of the present invention solves the problem that the inkjet printing, size fitting and pre-stacking in the later zone of the cutting line are slow when producing steel plates with high magnification, simultaneously performs pre-stacking operation after bilateral cutting and surface check in one cutting line, achieves synchronous inkjet printing/imprinting, size fitting and pre-stacking of the steel plates at two sites along the cutting line, and improves production rate of the cutting line and warehousing efficiency of finished products.

Actuator of a connecting-rod fracture splitting apparatus includes: a piston rod having one end portion extending through a lid of the cylinder and connected to a wedge; and a free piston slidably mounted on the piston rod and abuttable against the upper surface of the piston. By pressure fluid being supplied to act on the upper surface of the piston, the free piston imparts a preload to a hole of a big end section of the connecting rod. By pressure fluid being supplied to act on a region upward of the free piston, the free piston is driven downward to collide against the upper surface of the piston, so that divided mandrel members are moved apart from each other, via the piston rod and the wedge, to fracture a large end section of the connecting rod.

Machine for cracking a connecting rod having a small end and a big end, into a rod part and a cap part, the machine including positioning elements for positioning the connecting rod in a position for cracking, and an expandable element arranged to be inserted into a bore in said big end of the connecting rod so as to allow for splitting of the connecting rod into a rod part and a cap part by expanding the expandable element, where the machine further includes an electro press with a servomotor for actuating the expandable element.

Method for cutting soft metals, comprising the use of a cutting tool capable of being set in motion by ultrasonic vibration. The method is employed for cutting components used in the manufacture of an electrochemical storage device, for example, a lithium battery. These components include the anodes, the cathodes, the solid electrolytes, the current collectors and the separators. The method is also employed in a system for manufacturing and/or characterizing an electrochemical storage device.

Exemplary connecting rod cracking mandrels and methods are disclosed. A mandrel may include a pair of jaw elements slidably mounted relative to one another and separated from each other. Each one of the jaw elements has a pair of opposing side portions and a center portion disposed between the opposing side portions. Each one of the side portions is configured to contact an inner diameter surface of a bore of a connecting rod when the jaws are moved away from one another within the bore so as to break the connecting rod. The center portion is configured to be spaced apart from the inner diameter surface of the bore when the jaws are moved away from one another within the bore, such that the opposing side portions contact the connecting rod bore.

A method for fabricating a micromechanical part from a substrate in which the part is fabricated by providing a plurality of fasteners between the part and the substrate, the fasteners being sacrificial, characterized in that the fasteners include at least one hinge at the end of each fastener located beside the part, and in that the method includes a step of breaking the sacrificial fasteners. The micromechanical parts employing this type of sacrificial fastener are also described.

Extraction tongs with replaceable jaw tips include jaw tips with mating gripping projections. Each extraction tong includes a plurality of inward extending teeth. A thickness of the extraction tong is reduced at a bottom to form a jaw tip extension. A substantially triangular projection extends outward from opposing sides of the jaw tip extension. A plurality of holes are formed through the jaw tip extension. Each jaw tip includes a tong slot, which is sized to receive the thickness of the jaw tip extension. A substantially triangular slot is formed in opposing walls of the tong slot to receive the two substantially triangular projections. A plurality of counterbore holes are formed in opposing sides of the jaw tip. A first lengthwise projection is formed on a gripping surface of the first jaw tip. A pair of second lengthwise projections are formed on a gripping surface of the second jaw tip.

A method for trimming a rectangular container and an apparatus trimming a rectangular container are provided, by which an appropriate cut surface with a possible crack or burr suppressed can be obtained when a rectangular container is trimmed. When a punch cutter is initially allowed to cut into a rectangular tubular portion of an untrimmed rectangular container, the punch cutter is inclined relative to a thickness direction of a cut area of the rectangular tubular portion, and then, the punch cutter is circumferentially moved along a trim line on the rectangular tubular portion to cut the rectangular tubular portion.

The machine for cracking a connecting rod comprises an electro press with an electric motor (400) for actuating an expandable element. The electro press comprises a first S actuator part (410) and a second actuator part (430) arranged so that when the first actuator part is driven by the electric motor (400) from a first position to a second position, (a) the first actuator part (410) is first driven by the electric motor (400) from said first position (FIG. 12A) to an intermediate position (FIG. 12B), without displacing the second actuator part (430), and (b) subsequently the first actuator part (410) is further driven by the electric motor (400) from said intermediate position (FIG. 12B) to said second position (FIG. 12C), displacing the second actuator part from a non-expanding position to an expanding position.

A shear press for scrap including a machine body defining a compaction channel to contain the scrap and guide it in a sliding manner along a predetermined advance direction a compaction unit and blades. The compaction unit includes two mutually opposed jaws articulated to the machine bod according to axes of rotation parallel to each other and orthogonal to the advance direction of the scrap, and actuating members to rotate the jaws around the respective axes of rotation, in opposite directions, between an open configuration and a closed configuration. Each aw includes an operating surface to laterally de-limit the compaction channel when the jaw is in open configuration. The extreme point of a first rectilinear stretch with respect to the axis of rotation of the jaw is aligned to the latter along a direction of alignment which forms, with the first rectilinear stretch, an angle having its vertex facing the inner part of the compaction channel.
