Abstract
A method and apparatus are disclosed for sizing preferably small diameter sleeves, wherein the method comprises the steps in any effective order of: (a) providing an electrically conductive sleeve and a die; (b) positioning a portion of the sleeve in the die; (c) positioning a portion of an electrically conductive member inside the sleeve; (d) forming a direct electrical connection between the sleeve and the member; and (e) creating a magnetic field to expand the sleeve.
Claims18
A metal sizing method comprising:
- (a) providing an electrically conductive sleeve and a die, wherein the die has an inner surface at least partially covered by an electrically insulating layer wherein the extent of coverage of the insulating layer over the die inner surface and the thickness of the insulating layer are effective to prevent electrical shorting between the sleeve and the die;
- (b) positioning a portion of the sleeve in the die;
- (c) positioning a portion of an electrically conductive member inside the sleeve;
- (d) forming a direct electrical connection between the sleeve and the member;
- and
- (e) creating a magnetic field to expand the sleeve.

A metal sizing apparatus comprising:
- (a) a die;
- (b) a portion of an electrically conductive sleeve disposed in the die;
- (c) a portion of an electrically conductive member disposed in the sleeve;
- (d) connecting means for providing a direct electrical connection between the sleeve and the member, wherein the connecting means is coupled to the member and the connecting means is in direct electrical contact with the sleeve;
- and
- (e) a layer of an electrically insulating material between the die and the sleeve.
