Abstract
A mounting plate for an attachment with an insertable plug type tubular connector and a process for making the plate. The mounting plate comprises a sheet metal plate having length, width and body thickness T with a tubular nipple member projecting from one side. The nipple member is cold formed plastically from the body of the plate by a stamping process utilizing a progressive die. One of the intermediate die members is shaped such that it produces a tubular preform having a distal end portion with a wall thickness greater than the wall thickness of the opposite end portion adjacent to the plate. A subsequent die member reduces the excess wall thickness and extends the tubular member to an axial length equivalent to at least 3T measured from the distal end of the neck member to the surface on the opposite side of said plate. Subsequently, another die member precisely finishes a feature located in close proximity to the nipple member.
