摘要： A device for cold working pipe elements has two or more cams, each having a gear which meshes with a pinion to turn all of the cams. Each cam has a cam surface with a region of increasing radius and may have a region of constant radius extending around a cam body. Each cam also has a traction surface extending around a cam body. A region of reduced radius in each cam surface is aligned with a gap in the traction surface of each cam. The regions of reduced radius and gaps provide clearance for insertion and removal of the pipe element between the cams to form a circumferential groove when the cams are rotated.

摘要： A device for cold working pipe elements has two or more cams, each having a gear, the gears being synchronized to turn all of the cams. Each cam has a cam surface with a region of increasing radius and may have a region of constant radius extending around a cam body. One or more cams may also have a traction surface extending around a cam body. A discontinuity in each cam surface is aligned with a gap in the traction surface of each cam. The discontinuities and gaps provide clearance for insertion and removal of the pipe element between the cams to form a circumferential groove when the cams are rotated. An engagement body is mounted between the cams to engage and disengage from a stop surface on one of the cams. Engagement between the engagement body and a stop surface prevents rotation of the cams.

摘要： A device for forming circumferential grooves in pipe elements uses multiple geared cam bodies mounted on a carriage which rotates about a fixed pinion. The gears engage with the pinion which causes the geared cam bodies to rotate relative to the carriage. Traction surfaces and cam surfaces on the cam bodies traverse the outer surface of the pipe element and impress a circumferential groove therein. To substantially prevent rotation of the pipe element the pitch circle diameter of the pinion equals the outer diameter of the pipe element and the pitch circle diameters of the traction surfaces equal the pitch circle diameters of the gears.

摘要： A liquid reservoir includes a housing and a cover hermetically fixed to the housing, and further includes a flow guiding pipe having one end connected with the housing, and a filter assembly arranged in the housing and including first and second position-limiting assemblies, a filter member, and a molecular sieve. The first position-limiting assembly includes at least a first position-limiting member having a bottom portion, first and second protrusions. A part of an outer side wall of the flow guiding pipe is limited by and in cooperation with an inner side wall of the first protrusion which is located on an outer peripheral side of the part of the outer side wall of the flow guiding pipe. An outer side wall of the second protrusion is located on an inner peripheral side of a part of an inner sidewall of the housing.

摘要： A method for producing a profiled hollow shaft for a telescopic steering shaft of a motor vehicle may involve providing a hollow shaft to be processed, a profile mandrel, and a roller head comprising at least one roller. The method may further involve introducing the profile mandrel into the hollow shaft in order to produce a groove in the hollow shaft. The method may also involve moving the profile mandrel and the hollow shaft together relative to the roller head, wherein movement of the profile mandrel and the hollow shaft relative to the roller head is performed exclusively in a direction of a longitudinal axis of the hollow shaft in order to form a groove.

摘要： A tool for manufacturing blanks and a process for stacking and destacking the blanks in a production line are provided. The tool is incorporated into a blanking die used to trim a metal sheet and form the blanks. When the blanks are stacked, the destacking formations provide gaps between the adjacent blanks. The gaps provide an entry to blast air and thus reliably separate the blanks for pick up, so that only one blank is picked up at a time. The tool includes a deforming unit that has an engagement element for pressing deformations into the metal sheet. The deformations are pressed adjacent to at least one edge of the metal sheet so that when the metal sheet is trimmed, and the blanks are stacked, they are spaced by the deformations by adjacently stacked blanks.

摘要： Provided is a method of forming a locking ridge for a case of forming the locking ridge on an outer peripheral surface of a joint portion by form rolling, the method realizing a joint portion structure which is superior in pipe detachment prevention performance when pipes with locking ridges are connected by fixing pipe ends with a housing. Using a convex roller arranged inside the workpiece pipe body and a forming circular groove arranged outside the pipe body, the locking ridge is form-rolled such that an upright wall portion thereof is raised at an angle of at least 65° and no greater than 90° with respect to the outer peripheral surface in the pipe axis direction, and that a height of the locking ridge from the outer peripheral surface to the apex of the tip portion is at least a total of curvature radii of faces of the processing means in contact with the pipe body.
