摘要:
A cold rolling method for manufacturing a profile (16) from a one-piece rolling stock in form of initial material (6; 56) with a plurality of rolls (26, 36, 46; 6, 76, 86) each having a deforming region (28, 38, 48; 68, 78, 88) for deforming the initial material (6; 56) includes bending the initial material (6; 56) with formation at least one folded section (8) extending in a rolling direction of the initial material (6; 56), and deforming the initial material (6; 56) in its width direction with reduction of its thickness at least in one region.

A conduit hanger with at least one bracket element to receive a pipe, with a load-distribution plate that is placed into the bracket element, and with a fastening device for fastening the load-distribution plate to the bracket element. The fastening device has at least one catching element to grip the bracket element as well as a counter-bearing element, which are arranged offset on the load-distribution plate in the lengthwise direction of the plate, and between which a holding space is formed for the bracket element, and that the front of the bracket element has at least one recess that corresponds to the catching element so that the bracket element can be placed into the holding space.
摘要:
A track connection element for positioning a track body, which exhibits an interior, on a hanging element is disclosed. The track connection element exhibits two sidewalls, distanced from each other, which both exhibit an insertion section for insertion of the track connection element into the interior and a connection section connecting the sidewalls, which section has a recess for the hanging element. The sidewalls are reduced in terms of height in certain areas in the area of the insertion section. Further, a fastening device with such a track connection element is disclosed.

A method of reducing thickness of unbroken rolling stock (14) by longitudinal rolling includes deforming the rolling stock (14) in the width direction with deformation regions (26 to 29; 86 to 88) of the rolls (22 to 25; 82 to 84) penetrating in the rolling stock to the same depth.
摘要:
A method for producing a profile from a sheet-metal strip is disclosed. The sheet-metal strip is bent at least twice during a first stage, where, as viewed in the cross-section of the sheet-metal strip, a center section as well as two flank sections are formed, which project angularly from two opposing end regions of the center section. During a second stage following the first stage, the center section is compressed by two complementary roller arrangements which engage on the two opposing end regions of the center section, and the sheet-metal strip is thereby locally thickened.
摘要:
A roller forming device and method for forming a material provided with geometric elements, in particular holes, is disclosed. The device has at least one forming roller and at least one counter roller, wherein a roll gap is configured between the forming roller and the counter roller for carrying through the material. The forming roller has a molding structure on its cylindrical surface, which molds the material when the material runs through the roll gap. The forming roller has carrier elements for an engagement with the geometric elements of the material running through the roll gap.
摘要:
A fastening arrangement, including a quick-action nut that has two nut parts. The nut parts each have a groove to receive a threaded rod, and including a locking element with at least one passage opening for securing the quick-action nut to the threaded rod. In the passage opening, the locking element has a locking surface for pressing the nut parts against the threaded rod as well as a centering surface for centering the threaded rod in the passage opening. In the passage opening, the locking element has a transition surface that adjoins the locking surface and the centering surface, and that runs between the locking surface and the centering surface.
摘要:
A line fastening device for fastening a line on a rail body which has a mounting opening is disclosed. The device includes a bracket element that has two spaced-apart legs, each with two rear engagement sections for engaging behind opposing edges of the mounting opening, which are provided on a free end region of the corresponding leg, and with a tensioning device for bracing the line fastening device on the rail body. Each leg has a first leg part and a second leg part that is spaced apart from the first leg part by a gap. The gap extends partially along the leg starting from the free end region of the leg. The leg parts of the leg are spring elastic.
摘要:
A profile formed of a strip-shaped rolling stock and including at least one thickness-reduced section (16) having a thickness (D) that is smaller than the initial material thickness (W) of the rolling stock, at least one bend (17; 18), and at least one thickened region (21, 22) provided in a region of the at least one bend (17, 18) and having a material thickness (H) greater than the initial material thickness (W) of the rolling stock the profile (11) is formed of.
摘要:
A process of producing profiles whose cross-section is variable in the longitudinal direction, characterised by the process stages of cutting a blank 31 with a substantially constant width along a longitudinal direction, deforming the blank 31 by deep-drawing to form an open profile whose cross-section is variable along the longitudinal direction, and cutting the flanges projecting from the open profile.
