The bulk volume of large numbers of loose, separated, multiply bent, irregularly shaped scrap sheet metal is temporarily reduced, for transportation and storage of the metal for recycling purposes, by compressing the metal into temporary, compacted wafers formed of successively compacted layers. The apparatus includes a load chamber which is axially aligned with a compression chamber and a reciprocating ram which passes through the chambers towards an anvil plate which closes the discharge end of the compression chamber. A pre-determined quantity of loose pieces is placed within the load chamber. The reciprocating ram compresses the pieces of that batch into a thin layer. Successive batches are compressed into overlapping layers which are temporarily bound together, face-to-face, to form a unitary wafer, by temporarily bending and intertwining the peripheral edges of the layers. The layers are subsequently separated for recycling by depositing into a melt furnace.

The present invention provides a method and apparatus for forming thin wall sheet into a mechanically locked shell by providing a Mandrel that is shaped the same as the required shell and a set of forming rollers that forms the said sheet around the said mandrel. And providing gathering and forming and center bares that are parallel to the horizontal axis of the said mandrel and are moved to form the two edges of the said sheet over the said center bar. And wherein the said gathering and forming and center bars are moved to open or up position. And providing Lockseaming rollers that are moved along the axis of the said mandrel such that the said Lockseaming rollers will progressively form the said two edges into the said mechanical lock commonly known to those who are skilled in the art as a Lockseam.

A method for joining metal components includes a body and at least a sideboard. A plurality of lock members are installed on a side of the body. Each of the lock members is punched directly and extended into a shape for being cut into two corresponding bending parts. A plurality of holes is installed in the sideboard corresponding to each of the lock members for intersecting the body and the sideboard to combine each other with further press. Additionally, in the present invention, the body connects with each of the sideboard quickly and firmly, and less components and time are required for production.

A sheet hydroforming method is disclosed wherein two stacked metallic sheets are clamped between a pair of upper and lower dies 10, 11 and a fluid is introduced and pressurized between mating surfaces of the metallic sheets, causing the metallic sheets to bulge into a space defined by die cavities 10b and 11b. A thru-hole 11d for introducing the fluid is formed in one of the dies so as to lead to a holding surface of the die, while a pierced hole for introducing the fluid is formed in one of the metallic sheets in a portion of the one metallic sheet which portion is in contact with a holding surface 10a (10b) of one of the dies, the pierced hole being positioned with the thru-hole 11d, then the fluid is introduced in a pressurized state between mating surfaces of the metallic sheets from the thru-hole through the pierced hole, thereby causing the metallic sheets to bulge. According to this method, a pressurized fluid can be introduced between the mating surfaces of blanks easily without leakage of the fluid. Not only the efficiency of the sheet hydroforming method but also the dent resistance of a formed part can be improved.
摘要:
A joined metal-resin plate body having a metal plate (1, 12) and a resin plate (2, 13) joined together, in which an insert member having a through-hole therein is embedded in the resin plate. The insert member is in close contact with the resin of the resin plate in the outer periphery of the insert member except for the faces where the through-hole opens. The metal plate has a metallic joining member (4, 16) adhered thereto. The resin plate is joined to the metal plate with the aid of the joining member fitted in the through-hole. The insert member and the surrounding resin have elastic stresses (F3, F4), which give rise to a sufficient joining strength among the joining member, the insert member and the resin plate. The stress of the surrounding resin is due to elastic deformation. The amount (V2-V3) of the elastic deformation is smaller than the amount (V2) of deformation of the insert member which can give rise to an elastic stress (F3) of the insert member.

A method and apparatus for forming the locking bend on a Pittsburgh type seam used in joining the sections during assembly of box-shaped sheet metal ducts. The apparatus provides a means for securely holding the duct without the use of a mandrel to permit the sheet metal along the seam to be bent over by a forming roller moving along the seam so as to complete the joint and lock the seam.

A method is disclosed of adjusting the light-emission of a light-emitting diode to a predetermined output level for a given driving current. The light-emitting diode is irradiated with a laser beam in a manner to burn tiny holes in the light-emitting surface to such an extent that said predetermined output level is obtained. The invention furthermore comprises a method of obtaining a substantially uniform light output of an array of light-emitting diodes.
