摘要： A method of manufacturing a trailer hitch receiver tube with an integral reinforcing collar is described. A two piece die having an interior shape and dimensions conforming to the shape and dimensions of a selected trailer hitch receiver tube is provided, the two pieces of the die being a right half and a left half. Each of the right and left halves of the die are provided with means to forcefully move the die from an open position to a closed position around a workpiece. The die, around an upper edge thereof is provided with a relief cavity around its perimeter having the shape of a reinforcement collar. A base mandrel is provided between the right and left halves of the die, the base mandrel having a size and shape conforming to the size and shape of the interior of a trailer hitch receiver tube, and the base mandrel having a height less than the die. A steel receiver tube is positioned on the base mandrel, the tube having a height greater than the die halves. The die halves are then closed forcefully against the receiver tube. A forming mandrel is provided above the receiver tube. The forming mandrel has a longitudinal portion that conforms in shape to the interior of the receiver tube, and a lateral, forming portion for bearing against the upper edge of the receiver tube to form the upper portion of a receiver tube into a reinforcing collar by deforming the upper end of said tube into the relief cavity. An upper edge of the receiver tube is then forcefully struck with the forming portion of the forming mandrel, to form the collar, wherein the longitudinal portion of the forming mandrel closely approaches an upper surface of the base mandrel after the collar is formed.

摘要： A method for making a flat sheet pan includes providing a piece of material having known dimensions; and forming a baking surface therein; forming an upwardly extending tension bow in the baking surface for providing structural reinforcement to the baking surface; forming a sidewall portion that surrounds the entire baking surface and defines an interior surface of the sheet pan and an exterior surface of the sheet pan; forming a structural reinforcement rib in the sidewall portion; providing a band of material that surrounds an entire upper region of the sidewall portion above the structural reinforcement rib that is operative to provide structural reinforcement to the sheet pan; rolling the topmost region of the sidewall portion downward and away from the baking surface to form a rim having an outside portion that defines the outer edge of the sheet pan and an inside portion that abuts the sidewall portion on the exterior surface of the sheet pan; and completely enclosing the band of material within the rim by crimping the inside portion of the rim against the exterior surface of the sheet pan for creating a seal that prevents contaminants from entering the interior of the rim.

摘要： A tube flanging method includes the steps of: disposing a tube such that an edge thereof is exposed to the outside of a forming mold while the tube is inserted into the forming mold; applying an external force to the exposed edge of the tube to expand the exposed edge of the tube; applying an external force to the expanded edge to bend the expanded edge toward an outer surface of the forming mold; and applying an external force to the bent edge to form a flange, the flange having a linearly integrated cross section and being perpendicular to the longitudinal direction of the tube. With this configuration, it is possible to bend the tube to form the flange at a uniform thickness.

摘要： A back plate for use with a backlight module, a backlight module using the same, and the manufacturing method thereof are provided. The back plate includes a plate body and a side wall. The side wall extends out from the edge of the plate body and includes a wall body and a bending part, wherein the thickness of the wall body is less or equal to 0.12 mm. The bending part is formed by bending a plurality of bending sheets outward from the top of the wall body, wherein the thickness of each bending sheet is less or equal to 0.12 mm. The backlight module includes the back plate and a light source module, wherein the light source module is disposed on the plate body and adjacent to the inner side of the side wall.

摘要： A strip rolling mill apparatus as well as a method is provided for rolling out an endless strip from a cast ring which may be produced by casting an end, continuous casting or centrifugal casting. In this method of rolling an endless strip from a cast ring, the cast ring in one embodiment of the invention is vertically on end while being rolled out to the strip. The annular-strip rolling mill consists basically of at least one pair of live rolls and one pair of drawing rolls which are displaceable by a drawing carriage. The live rolls and the drawing rolls, with pertaining brackets therefor, are disposed vertically on end and supported. A roll table, spherical table or the like which extends over the range of displacement of the drawing rolls is provided for the support of the ring or strip being rolled.
