Abstract
Abstract A component preforming machine for forming the leads from electronic components so that they may be inserted in, and space the component from a circuit board. The machine incorporates a pair of dies that are mounted on the base of the machine. A pneumatic cylinder forces one of the dies toward the other to form the leads. The fixed die is supported on the base of the machine in two pin and bushing combinations, and held in place by a single screw. A die configuration is provided for forming the leads of radial lead components so that the leads may be inserted in the board to space the component from the board and to hold the component upright during processing until the component is firmly secured by soldering. The component leads after forming in this die incorporate oppositely directed semi-circular crimps intermediate the ends of the leads. The crimps eliminate the tendency of the component to rock toward one direction or the other. Each die incorporates a cylindrical protrusion that cooperates with a cylindrical cavity in the opposing die.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
116 words
A component preforming machine for crimping the leads of an electronic component to space the body of said component from a circuit board comprising: base means, first and second die means received on said base means for crimping the leads of a component having at least two leads, the crimped portion of at least two of said leads being in a substantially semicircular configuration, said die means being relatively moveable, power means for forcing Said first and second die means toward one another, at least one of said die means being secured against movement with respect to said base means by cooperating pin and bushing combinations, said pin and bushing combinations comprising high strength, hardened material.
Claim 2
Dependent Claim
116 words
A component preforming machine for crimping the leads of an electronic component to space the body of said component from a circuit board comprising: base means, first and second die means received on said base means for crimping the leads of a component having at least two leads, the crimped portion of at least two of said leads being in a substantially semicircular configuration, said die means being relatively moveable, power means for forcing Said first and second die means toward one another, at least one of said die means being secured against movement with respect to said base means by cooperating pin and bushing combinations, said pin and bushing combinations comprising high strength, hardened material.
Claim 3
Dependent Claim
28 words
The component preforming machine of claim 1 wherein: said pin and bushing combinations are in an engaged relationship by a removable fastener securing said die to said base.
Claim 4
Dependent Claim
79 words
A pair of dies for a component preforming machine for crimping the leads of an electronic component to space the body of said component from a circuit board comprising: first and second die means for receiving the generally vertically oriented lead of said component and for forming said leads into arcuate sectors that open in opposite directions on opposed leads, said arcuate sectors being substantially right angularly related to the plane that includes the straight portions of said leads.
Claim 5
Dependent Claim
79 words
A pair of dies for a component preforming machine for crimping the leads of an electronic component to space the body of said component from a circuit board comprising: first and second die means for receiving the generally vertically oriented lead of said component and for forming said leads into arcuate sectors that open in opposite directions on opposed leads, said arcuate sectors being substantially right angularly related to the plane that includes the straight portions of said leads.
Claim 6
Dependent Claim
21 words
The dies of claim 3 wherein: said die means for cutting off said leads to a predetermined total length after forming.
Claim 7
Dependent Claim
48 words
The dies of claim 3 wherein: said first die means comprises a generally cylindrical protrusion and a horizontally opposed cylindrical cavity; and said second die means comprises cooperative protrusion and cavity means for being received in and over said cylindrical protrusions and cavity of said first die means.
Claim 8
Dependent Claim
82 words
The dies of claim 5 wherein: the protrusion of said second die means comprises a cylindrical means having an outer diameter that is smaller than the inner diameter of said first die means for accommodating the lead of the component to be formed; and the cavity of said second die means comprises cylindrical means having an inside diameter larger than the outer diameter of said cylindrical protrusion of said first die means for accommodating the lead of the component to be formed.
Claim 9
Dependent Claim
23 words
The dies of claim 5 wherein: said first and second die means for accommodating components having a substantial variation in spacing between leads.
