A joint structure and a wind regulator having high separation strength, A lift arm (5) is provided with: a tapered through-hole (35) which has formed thereon a first inner wall section (33) work-hardened by plastic deformation; and a raised section (45) which has an inner wall surface (41) interconnected with an inner wall surface (31) of the tapered through-hole (35) and which has formed thereon a second inner wall section (43) work-hardened by plastic deformation. A protrusion (1) is formed on a driven gear (3). The protrusion (1) is fitted from the tapered through-hole (35) up to the raised section (45), has an outer wall section (53) work-hardened by plastic deformation, and has an outer wall surface (35) in close contact with the inner wall surface (31) of the tapered through-hole (35) and with at least a part of the inner wall surface (41) of the raised section (45),

Eine Anordnung (11) eines Stapels (10) umfasst zwei plattenförmige Werkstücke (12, 13), die durch einen Durchzug (14) miteinander verbunden sind, wobei Material des einen ersten Werkstückes (12) durch eine Durchgangsöffnung (15) des anderen Werkstückes (13) durchgezogen ist. Der Rand (17) der Durchgangsöffnung (15) in dem anderen Werkstück (13) verengt sich konisch in Richtung des ersten Werkstückes (12).
摘要:
A sheet metal hemming method and apparatus for securing inner and outer sheet metal panels (20,22) together by forming a generally flat hem (24) along respective peripheries of the two panels. A fixture (42) receives and holds an outer sheet metal panel that is formed to include an upstanding border flange (25'). An inner sheet metal panel is stacked on top of the outer panel. A hemming tool (32) movably supported adjacent the fixture bends the upstanding border flange of the outer sheet metal panel over a periphery of the inner panel and into a position forming an acute angle relative to an underlying portion of the outer panel. The hemming tool also bends an outer portion (30) of the border flange down onto the periphery of the inner panel and into a position over and generally parallel to the underlying portion of the outer sheet metal panel.
摘要:
Die Verbindung von wenigstens zwei Profilteilen (10, 18) zu Platten, Tafeln, Pfosten, Streben, Einfassungen, Abstützungen u.dgl. besteht aus einer an dem einen Profilteil (18) angeformten Nut (20) zur Aufnahme einer Feder (11) eines anderen Profilteiles (10). Dabei weist die Nut (20) wenigstens eine Hinterschneidung zur Aufnahme des Klemmschenkels der Feder (11) auf. Die Nut (20) des einen Profilteiles (18) weist einen durch eine Nutgrundverbreiterung (22) gebildeten hammerkopfartigen Querschnitt auf, während die Feder (11) des anderen Profilteiles am Federkopf (10) die Engstelle der Nut passierbare Spreizstege (16) aufweist, die beim Eintreiben der Feder (11) in die Nut (20) durch bleibende Verformung in der Nutgrundverbreiterung (22) unlösbar verklemmen.
摘要:
A side member (2) (example of second member) having a hollow shape is inserted into holes (1a) formed in a cross member (1) (example of first member) (member insertion step). The cross member (1) and the side member (2) are joined by caulking by expanding an insertion portion (A) of the side member (2) from the inside of the insertion portion (A) (caulked junction step). The insertion portion (A) of the side member (2) is a portion inserted into the cross member (1).
摘要:
Provided are a method for splitting longitudinally an end part of a metal plate or a metal rod having a rectangular, polygonal, or elliptical shape, in which the length of incision in the split portion can be freely adjusted and smooth split face can be formed; a metal part manufactured by such method; and a method for bonding such metal part. The present invention is characterized by the process comprising the steps of securing a metal plate by pinching both sides thereof with a clamping device, or securing a metal rod by pinching at least two opposite-facing portions on the periphery thereof with a clamping device; splitting longitudinally by slitting or cleaving the metal plate, or the metal rod, by pressing a slitting punch or a cleaving punch against the face of one end of the metal plate, or the metal rod; and advancing the splitting further by repeating the same operation of pressing the same punch stated above against the cleft of the splitting; and is characterized further in that, in each time of the press-splitting operation, the position of the clamping device on at least one side is moved in advance of the next pressing by a stroke corresponding to the distance from one end of the metal plate, or the metal rod, to the distal end of a split-desired portion.
