摘要： A method of manufacturing a perforated sheet which has at least one hole. The method includes introducing at least two spaced boreholes into a sheet, the at least two spaced boreholes being formed so that they each pass through a thickness of the sheet, introducing a continuous cut between the at least two spaced boreholes in the sheet, and bending open a section of the sheet which is adjacent to the continuous cut so as to form a hole.

摘要： A hand-held knockout driver includes a main housing having a handle portion, a motor positioned within the main housing, a pump assembly driven by the motor, and a secondary housing coupled to the main housing and defining a bore therein. The hand-held knockout driver also includes a working piston moveable within the bore from a rest position to an actuated position to define a piston throw distance therebetween. The hand-held knockout driver also includes a draw stud coupled to the working piston, a die coupled to the secondary housing, and a punch coupled to the draw stud opposite the working piston for movement therewith relative to the die. The die has a depth greater than the piston throw distance.

摘要： A torsion bar is provided that is easy, quick, and cost effective to manufacture. The torsion bar may extend along an axis and have a first end and a second end that is spaced from the first end. The torsion bar may have an active section positioned between the first and second ends. The active section may also have a length defined along the axis. A cross-section transverse to the axis may define a contour of the torsion bar where the contour may be uniform along the length of the active section. The contour may define at least one of a polygon and a polygon-like shape.

摘要： A tool includes first and second tool parts that move toward one another, at least one processing device provided on the first tool part, and at least two counter devices provided on the second tool part. The processing device and the counter devices are rotatable relative to one another about at least one positioning axis, and the counter devices are aligned relative to one another along a direction of relative rotational movement of the processing device and the counter devices. The processing device and a first counter device are allocated to one another by at least a first defined processing parameter, and the processing device and a second counter device are allocated to one another by at least a second defined processing parameter. The first processing parameter is different than the second processing parameter.

摘要： The invention relates to an adjustable intelligent digital-display plate punching device with inclined holes positioning which includes a base, a movable pressing plate, a fixed pressing plate, an adjusting plate and a supporting device. The base is provided with a chamber, an eclectic cylinder, a rack, and a first T-shaped chute. Two protruding plates are disposed on the movable pressing plate. A ratchet mechanism is provided between the protruding plates. The ratchet mechanism meshes with the rack. Two ends of the adjusting plate are provided with a curved plate. The adjusting plate and the fixed pressing plate are slidably connected to each other. The supporting device includes a first supporting plate with a curved structure, a second supporting plate provided with a through hole, and a supporting rod. The adjustable intelligent digital-display plate punching device with inclined holes positioning of the invention has simple and reasonable structure, easy to use, high intelligence, and high versatility, etc., which effectively solves the problems of low precision and inconvenience of punching angles adjustment for existing plate punching devices.

摘要： Provided is an abnormality prediction system and an abnormality prediction method that are capable of predicting an abnormality occurring in a die that is used in a press machine. A die abnormality prediction system (50) includes: an acoustic emission (AE) sensor (62) configured to detect an elastic wave that occurs in a processing portion of a die during processing performed by a press machine using the die; a stamping load detection sensor (61) configured to detect a parameter (a stamping load) other than a parameter regarding the elastic wave, out of parameters regarding a state of the die during the processing performed by the press machine using the die; a score calculation unit (56) configured to calculate an abnormality prediction score of the die based on an output signal from the AE sensor (62) and an output signal from the stamping load detection sensor (61); and an abnormality prediction unit (57) configured to predict an abnormality occurring in the die, based on a result of the calculation performed by the score calculation unit (56).

摘要： A rotary position sensor assembly (10) for detecting the angular position of the rotor (104) of a motor. The assembly (10) includes at least one sensor (12) and a sensor target (14) which is moveable relative to the sensor (12). The sensor target (14) comprises a tubular body (16) with a plurality of integrally-formed radially-extending sections (18). These sections (18) include two radial upper edge portions (24) which are supported by a radially-extending support which is set back from the edge portions (24). Each of the two upper edge portions (24) provide a target for the sensor. A sensor target (14) for use in a position sensor assembly (10), a method of production of the sensor target (14), and an electromechanical actuator which utilises the rotary position sensor assembly (10) are also provided.

摘要： The disclosure comprises a method for producing a sleeve-like passage for a bearing accommodation in a metallic wheel control arm of a vehicle. The method may include placing a wheel control arm end of the wheel control arm onto a pressing plate of a pressing tool; and forming a tapered wall in the wheel control arm end and a circumferential collar around the tapered wall in the wheel control arm end, wherein the forming comprises pressing the wheel control arm end against the pressing plate using a pressing punch, wherein a volume of metal of the wheel control arm end is displaced into a circumferential cavity due to the pressing of the wheel control arm end against the pressing plate,; and perforating the tapered wall to obtain the sleeve-like passage.
