摘要： A vacuum plate which may be used in a system in which sheet material articles are handled by a vacuum plate. The vacuum plate comprises a first wall, a plurality of bores in the first wall, and at least one air outlet for connection to a source of vacuum pressure for applying a vacuum pressure to the bores. The first wall provides, in use, a vacuum lifting surface for pulling and holding the sheet material article to the vacuum surface when vacuum pressure is applied to the bores. Each bore comprises a flared opening terminating at the vacuum surface for admitting air pulled through the bore by the applied vacuum pressure, and opposite this opening, an exit for the air pulled through the bore, this exit being surrounded by a rim that extends above a surrounding surface of the second side of the first wall.

摘要： A sprocket for a bicycle drive train comprising an outer ring having external teeth for engaging in a bicycle chain, and an inner ring coaxially disposed with the outer ring and is connected to the outer ring in a rotationally fixed manner. The inner ring has a central opening. A circumferential collar is configured to be integral with the inner ring and projects axially to one side of the inner ring and is configured as a continuous collar. An internal profile having a plurality of radially inward-projecting radial protrusions is provided on the radially inner side of the collar, and an external profile having a plurality of radial depressions, which in number and arrangement correspond to the radial protrusions of the internal profile, is provided on the radially outer side of the collar.

摘要： A laminated member as a laminate of a plurality of alloy ribbons is used. The laminated member has a side surface with a fracture surface. A laminated body as a laminate of the laminated member is used. A motor that includes a core using the laminated body is used. A method for manufacturing a laminated member is used that includes: fixing a plurality of amorphous ribbons to one another in a part of layers of the amorphous ribbons after laminating the amorphous ribbons; and punching a laminated member by cutting the laminate of the amorphous ribbons at a location that excludes the portion fixing the amorphous ribbons in the laminate.

摘要： Disclosed herein is a press molding method for forming a press-molded product having a flange including a special-shaped portion. The method includes: a trimming step of determining an outer peripheral edge of the flange and forming the special-shaped portion; and a finishing step of molding the flange into a final product shape position of the press-molded product after the trimming step. The flange includes a first flange portion including at least a portion of an outer peripheral edge of the special-shaped portion. In the trimming step, the first flange portion is press-molded into a preform position deeper in a thickness direction of the first flange portion than a final product shape position of the first flange portion, and in the finishing step, return molding of lifting the first flange portion in the thickness direction of the first flange portion to the final product shape position of the first flange portion is performed.

摘要： In a method for manufacturing lamination stacks of controlled height in a tool, starting material is provided as continuous strip delivered from a coil or as an individual sheet. Laminations are punched from the starting material in several punching steps to a required contour of the laminations. A heat-curing adhesive is applied onto the laminations prior to performing a last punching step. The laminations are combined to a lamination stack. The laminations of the lamination stack are partially or completely heated in a lamination storage. The adhesive is liquefied by heating the lamination stack to build up adhesion and then solidified. Curing the adhesive at the liquefying temperature or solidifying the adhesive in the tool by cooling and subsequently heating the adhesive to a temperature below the liquefying temperature is possible so that the adhesive does not melt but undergoes further curing resulting in higher temperature stability.
