Abstract: The present invention relates to methods of working sheet metal, and sheet metal working apparatus for performing such methods. Such methods include steps of providing a sheet metal workpiece having first and second surfaces opposed to each other and at least one edge, bending the workpiece to form at least a first sidewall portion defined between the edge and a basal region, the first sidewall portion thereby defining a curved fold region in the sheet metal workpiece adjacent the first sidewall portion. Following this, first anvil tool and a first forming tool are provided for contact with and constraint of the first and second surfaces of the sheet metal workpiece respectively. The forming tool and/or the anvil tool are then progressively slid along the curved fold region to cause shear material transfer in the curved fold region to further deform the curved fold region. Such methods can allow for formation of components of similar shape as made at present by deep drawing methods, but with less wastage of the starting material.

Abstract: A metal part is hot formed by placing a metal part blank on a forming tool and installing a fabric cover over the forming tool, overlying the metal part blank. The fabric is at least partially wrapped around the metal part blank. The metal part blank is heated to a temperature sufficient to allow forming of the metal part blank. Forming pressure is applied to the metal part blank that conforms the metal part blank to the forming tool by tensioning the fabric.

Abstract: A “negative creep” corrugated gasket of Shape Memory Alloy (SMA) for Bolted Flanged Connections (BFCs) operates under temperatures that are within the temperature interval of reverse martensitic phase transformation from martensite to austenite of the SMA. Gasket corrugation is shape-memorized to operating “swelling” at temperature of direct martensitic phase transformation from austenite to martensite of the SMA being compressed to obtain some quantity of residual contraction corresponding to stress-induced martensite formation. A free “swelling” of deformed gasket corrugation at operating temperature defines the “negative creep” effect of the gasket, and it is blocked by rigid flanges with appearance of reactive shape-recovering stresses between the gasket corrugation and flange surfaces. The reactive shape-recovering stresses have direction inverse to the direction of operating creep of the gasket providing leak-tight, multiple, automatic and continuous seal between the flanges of the BFC. Methods of manufacturing of “negative creep” corrugated gasket are disclosed.

Abstract: A portable angle bender for strip metal. The bender has a shallow U-shaped base having a bending fixture mounted to two upstanding side walls. The bending fixture has two guide members joined at a hinge and pivotally attached to the base on their other ends. One guide member pivots about a fixed axis, while the other may slide relative the base to alter the included angle of the fixture. Each guide member has a slider plate mounted thereunder to form a gap with a top plate to which the central hinge is attached. The gaps are open toward the hinge so as to enable endwise insertion of an angled strip of metal into the fixture. The slider members are constructed of a non-stick material, and the gap is dimensioned to facilitate advancement of the strip through the fixture. A quick-release locking nut is utilized for adjustments to the bending angle, and an indicator is mounted to one of the guide members for registration with a series of angle markings inscribed on the base.

Abstract: A method of producing a coupling for pipes includes the steps of subjecting a predetermined length of desired cross-sectional profiled material to a bending process in a mould having a semi-circular portion to form an item of semi-circular shape; forming bent ends of predetermined size on the profiled material; and then coining the bent ends to lie in an identical horizontal plane as a horizontal diameter of the item of semi-circular shape. The coining step is accompanied by a substep of forcing excess material from the predetermined length of profiled material into a zone between the semi-circular portion of the mould and the bent ends of predetermined size on the profiled material.
