Patent ID: 8726712

Claim:
An apparatus for processing a sealing lip of a metal can, the apparatus comprising: a pressurization block which applies pressure downward; an interlocking means comprising first to third moving bodies elastically lifted up and lowered down by the pressurization block; and a lip processing member which presses the sealing lip of the metal can from the inside and outside of the metal can while moving in the radial direction of the metal can by the lifting and lowering motion of the interlocking means, wherein the first moving body comprises: an upper receiving body which is put on a projection of the pressurization block and includes fastening grooves, to which the fastening members inserted into the first through holes of the pressurization block are fastened; and a lower receiving body which is connected to the upper receiving body and includes an inclined surface which is tapered toward the center at lower end of an inner surface thereof, wherein the upper receiving body and lower receiving body are connected to each other in a manner that screw threads formed at lower end of the upper receiving body and upper end of the lower receiving body are engaged with each other, wherein the second moving body comprises: a first mold which is received in the inside of the projection of the pressurization block; a second mold which is located at the bottom of the first mold and includes stepped grooves formed on upper and lower surfaces; a third mold which is received in the stepped groove formed on the lower surface of the second mold; and a fourth mold which is located at the bottom of the second mold to surround the outer circumferential surface of the third mold and includes first and second locking projections which project inward and outward from the lower end.
