METHOD AND SYSTEM THAT PRODUCES FORMED PARTS BY A MULTI-STAGE PRESS
A method of producing shaped parts includes drawing in the wire in cycles conveying the wire; severing wire portions in cycles; gripping and feeding the wire portion into work area; shaping the wire portion in multiple stages to form a shaped part with shank and head portions; ejecting formed shaped parts in cycles; transporting the fully formed shaped parts with a pneumatic conveyor system including a transporting pipe with an insertion opening: arranging the insertion opening near an ejector system such that the finished shaped parts can be inserted into the insertion opening directly in a positionally oriented manner by the ejector system; successively feeding the finished shaped parts into the transporting pipe by the ejector system; taking up the shaped parts inserted into the transporting pipe by suction into the transporting pipe; and pneumatically transporting the shaped parts through the transporting pipe in a direction of a subsequent station.
Enlarged head fastener device and method of manufacture
An enlarged head fastener device and method for manufacturing the same is described. The enlarged head fastener device includes a shank and a head. The head extends outwardly from the shank in a transverse plane to define a head periphery. The head has an anterior side and a posterior side. The anterior side includes a bearing surface and a convergent transition portion that reinforces the head. The convergent transition portion extends between a large end adjacent the bearing surface to a small end adjacent the shank. At least one ridge formation projects from the anterior side of the head providing additional reinforcement. The ridge formation extends continuously between an outboard end positioned on the anterior side of the head adjacent the head periphery and an inboard end positioned on the shank. The head may be centered or offset relative to the shank.
Compressive indentation fastener device
A compression indentation fastener device is described comprising a shank and a head. The head extends outwardly from an end of the shank in a transverse plane to define a head periphery. The head has an anterior side and a posterior side. The anterior side includes an exposed area extending between the shank and the head periphery. The anterior side includes a relief portion in the form of a depression. The relief portion is open at the anterior side of the head such that the relief portion receives a volume of substrate material when the exposed area of the head impacts the substrate material. The head may be integral with the shank or the head may be comprised of discrete head portions that mate with one another. Additionally, the head may be centered on the end of the shank or offset relative to the shank.
