The method and apparatus for forming flanged holes and a resulting plate and tube assembly of the type used in fluid-to-fluid, such as gas-to-gas, liquidto-liquid and liquid-to-gas, heat exchangers. A depression is formed with the aid of a punch in a plastically deformable metal sheet such as steel, aluminum, copper and the like, while applying controlled counterpressure with the aid of a larger counterpunch so that material displaced from the space between the punches is laid upon the inner bore of a constraining die. Thus the wall of the depression is formed by purely compressive means. The base of the depression may then be removed to provide deep flanges of controlled dimensions free of cracks or splits.

A brake assembly machine for forming a hem in sheet metal has a top bar and a bottom bar opposite the top bar. The top bar and the bottom bar can move towards one another to hold sheet metal therebetween. The brake assembly machine also has an angle foot movable to a proximity of a bending bar that moves about a bending bar axis and includes a bending face. As the bending bar moves about the bending bar axis, the bending face of the bending bar can move closer to the angle foot and before the bending bar bending face contacts the angle foot, the angle foot moves to avoid contact with the bending bar.

SLOPED BOTTOM TANK

An improved tank bottom configuration formed from a flat metal plate of square or rectangular shape is disclosed. The plate is sheared to provide two adjacent sides which are tapered along their lengths and a notch is cut in each corner portion. By the use of stop and die members, the plate member is deformed to provide a bottom wall portion which slopes downwardly toward one corner and upwardly extending side wall portions which extend around the periphery of the bottom wall portion. A drain opening and a crease are formed in the bottom wall portion, with the crease being aligned with and spaced from the drain opening.

Acute-angle bending tool for hemming

An acute-angle bending tool 1 for hemming performs sectional bending, in which a portion of a flanged rim 3 formed in a sheet 2 via a bend 4 is folded so as to form an acute angle with the reverse side of the sheet 2, while shifting the processing position along the flanged rim 3, thereby performing acute-angle bending on the flanged rim 3. The tool is provided with a first die 5 having a support section 8 that supports the sheet 2 across the reverse side up along the bend 4, and a drive means 7 for driving a second die 6 in an advancing direction F and a retreating direction B with respect to the first die 5. The second die is provided with a pressing face that presses, when the die is driven in the advancing direction F, the outer side of the portion of the flanged-rim 3 of the sheet 2 supported on the first die 5, whereby sectional bending is carried out.

Method of fabricating sleeves for trampolines

A method of fabricating sleeves for trampolines includes steps of: first, bending a plate into a tube with a coupling seam bonded through a bonding process to form a sleeve; next, expanding an opening of the sleeve through an opening expansion means to form a body and an expanded opening section extended from the body; applying a compressive force to the expanded opening section to form an outer expanded portion and an inner folding portion. When the sleeve is coupled with a connection tube, the outer expanded portion and inner folding portion provide greater structural strength. Whether defects are formed on the coupling seam at the outer expanded portion and inner folding portion can be easily and visually detected after the fabrication process is finished. Thus defected sleeve can be instantly identified during the fabrication process to save extra inspection time. Fabrication productivity of trampolines also improves.
