Benefits of technology

[0022]FIG. 7I is a view of the bushing cut from the carrying web as shown at FIG. 7H.

Problems solved by technology

One clear disadvantage is that the dovetails of adjacent surfaces cannot slide into each other on a plane.
While the progressive stamping method is quick and easy to use, it requires dies and tooling and may not be adapted to the creation of curved or rounded items as each station is done on a plane.

Embodiment Construction

[0024]For the purposes of promoting and understanding the invention and principles disclosed herein, reference is now made to the preferred embodiments illustrated in the drawings, and specific language is used to describe the same. It is nevertheless understood that no limitation of the scope of the invention is thereby intended. Such alterations and further modifications in the illustrated devices and such further applications of the principles disclosed as illustrated herein are contemplated as would normally occur to one skilled in the art to which this disclosure relates.

[0025]Progressive die stamping is a metal working method where a long strip of metal also described as a carrying web 1 illustrated at 7A is slid and guided over a series of stations or steps where different operations are performed on a portion of the carrying web. In one embodiment the carrying web 1 is made of a C1050 heat treated to RC 43-48 Zinc per GMW3044 6U48 / 0 0.00025″ Clear Chromate fed into a machine...

Abstract

This disclosure relates to bushings produced with adapted dovetails for production on a carrying web of a progressive stamping machine at a plurality of stations. The bushing includes a regular shape male dovetail inserted into an irregular shape crenellated female opening at the conclusion of a plurality of operations at stations on a progressive stamping machine. Once the bushing is bent in shape, in a subsequent step, the regular shape male dovetail is punched to lock in place into the irregular shape crenellated female opening.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a non-provisional claiming priority from U.S. Provisional Application No. 61 / 303,543 filed on Feb. 11, 2010 entitled “BUSHING MADE FROM PROGRESSIVE DIE STAMPING.” U.S. Application No. 61 / 303,543 is hereby incorporated herein by reference.FIELD OF THE DISCLOSURE[0002]This disclosure relates to a bushing, a piece equipped with said bushing, or a method of producing either the bushing or the piece equipped therewith, and more specifically, to a bushing where the bushing is made using a progressive die stamping technology with a dovetail interface.BACKGROUND OF THE INVENTION[0003]Bushings are often thin sleeves made of a strong material inserted into a housing to provide a rotating element some support or to reinforce a piece having insufficient mechanical properties. For example, in a piece made of plastic, subject to abrasion or corrosion, a non abrasive or non corrosive metal bushing may be slid into a hole into the pie...
