PURPOSE: A mold structure for forming a crease preventing projection on a panel is provided to adjust the projected height of a projected block member forming the crease preventing projection on the panel with a screw and to improve working efficiency and cut down cost without cutting and welding processes to lower and heighten the height of the projected block member. CONSTITUTION: A structure(100) for a mold(15) forming a crease preventing projection(13) for absorbing creases generated on a panel(11) in a flanging process of the panel having an elliptical side to the panel is composed of a projected block member(10), a semicircular block member(20), and a pressurizing member(30). The projected block member is installed to slide inward the mold and one side of the projected block member is protruded out of the mold and contacted with the panel to form the crease preventing projection. The semicircular block member is made into a semicircle shape to fit into a semicircular space unit formed in the mold, and contacted with the side of which the projected block member is inserted into the mold. The pressurizing member pressurizes the side of the semicircular block member, slides the semicircular block member along the semicircular space unit, pressurizes the lower side of the projected block member and moves the projected block member upward and downward.

PURPOSE: A door inner panel fabricating method is provided to reduce manufacturing steps required for fabricating a door inner panel and to save manufacturing cost by forming the door inner panel using one mold after bonding two different members to each other to form the door inner panel. CONSTITUTION: Flange sections are formed at first ends of first and second steel plate(21a,21b), which have thickness different from each other. Then, the flange sections formed on the first and second steel plate(21a,21b) are parallel overlapped with each other in a length direction thereof. Then, the overlapping part of the flange sections is welded. After that, the welded steel plate is subject to a pressing process by using a press equipped with a mold having a predetermined shape.

PURPOSE: A hemming process is provided which is capable of improving production cost and quality problems by removing post-processes generated during the hemming process. CONSTITUTION: In a hemming process for a panel consisting of an inner plate(32) and an outer plate(30), the hemming process comprises the processes of flanging and clinching the edge of the outer plate(30) of the panel inward; coating adhesive comprising a plurality of ceramic balls(34) on a gap of the clinched part; resting the inner plate(32) by inserting the inner plate(32) of the panel into the coated adhesive; and hemming coupling the outer plate(30) of the panel to the inner plate(32) of the panel.
205 MOUNTING ELEMENT, MOUNTING ARRANGEMENT AND TOOL FOR MACHINING A MOUNTING ELEMENT PCT/DE2008001841 2008-11-07 WO2009059599A3 2009-09-03 VOIGT GERD
The invention relates to a mounting element (10) and a tool (52, 52a, 52b) for machining the mounting element (10), wherein the mounting element (10) comprises a ribbon (12) extending in a longitudinal direction and having a width (B) and a height (H) and (L), the width (B) being larger than the height (H), and transversal embossings (14), which are configured on the ribbon (12) and are disposed transversely to the longitudinal direction (L) substantially across the width (B) of the ribbon (12), the transversal embossings (14) having variable depths (T) across the width (B) of the ribbon (12).
206 ADJUSTABLE FLANGE FORMING APPARATUS PCT/US2007024168 2007-11-16 WO2008063601B1 2008-10-23 WALLE DAVID
A flange-forming apparatus allows a user to automatically adjust the device's roll forming stations, concurrently together, for changing the height of a flange formed into a metal web by the roll forming stations, e.g., for ductwork. The height is adjustable within an infinite range between set maximum and minimum limits. Each roll forming station includes upper and lower roll forming pairs, which cooperate for forming the flange or portion thereof. Each roll forming pair includes a first roll forming portion, and a second, coaxial roll forming portion that is axially moveable towards and away from the first roll forming portion. (The portions are in effect a laterally split roll forming die.) The second roll forming portions are rotatably supported on a plate-like adjustment linkage assembly, which can be shifted, using an array of motor driven screw members, towards or away from the first roll forming portions.
