摘要： A method of controlling the spacing between a material forming punch and a complemental die includes advancing a punch shell and a pressure sleeve into engagement with the material and holding the material with the sleeve and blanking it with the punch shell. The material is then preliminarily formed by clamping the periphery between the pressure sleeve and a die core ring and advancing a punch core past the top of the die core ring and clamping the material against a die core to establish the desired dimension. The material is then finally formed by further advancement of the punch core with the die core and die core ring moving together. The apparatus includes a die core and die core ring which are concentrically arranged and independently supported but movable into engagement with each other after a predetermined amount of travel so as to move together through any further travel caused by movement of a punch core against the die core.

摘要： A method of forming a container in one or more double acting presses includes the steps of blanking, drawing an inverted cup and reverse drawing the inverted cup while retaining a flange thereon at a first station and then transferring the cup to a second station where the cup is drawn to an inverted configuration and then reverse drawn to form a finished container again retaining the flange throughout. The drawing operations at each station are performed in a single stroke of the press. The apparatus at the first station includes a blank and draw punch and a fixed, hollow die core ring with the punch telescoping over the ring to form the inverted cup and a draw horn telescoping within the ring to reverse draw the cup. The apparatus at the second station includes a hollow redraw sleeve and a pressure sleeve telescoping over the redraw sleeve to invert the cup and a profile punch telescoping within the redraw sleeve to reverse draw the cup.

摘要： Method and apparatus for forming end closures for containers complete with a peripheral curl for attachment to the top of a container without press modification includes a unique split die core ring. The method includes performing the operations of blanking the end panel against the cut edge, forming the chuckwall against the die core ring with a punch and punch shell and finally setting the chuckwall by wiping over the radius of the die core ring against a fluidly supported piston and simultaneously applying a curl to the peripheral edge of the panel prior to completion and removal from the press station. The method is performed by utilization of a split die core ring having inner and outer concentric segments, the outer segment of which is withdrawn as the punch shell advances to initiate a curl between the inner face of the punch shell and the outer face of the fixed inner segment of the die core ring. The apparatus for carrying out the method includes a conventional double acting press with a punch core on the inner slide, a punch shell on the outer slide and a die core on the fixed base. A split die core ring is employed on the fixed base and comprises a fixed inner ring and movable outer ring. The inner and outer rings are designed so as to effectively operate as a single ring during the initial forming operation. During the curl forming operation, however, the punch shell moves the outer portion of the split die core ring out of the way and forms the curl in the peripheral edge surface of the closure in the space vacated thereby.

摘要： A system for forming unitary containers from flat metal stock includes a unique arrangement of both previously known and newly discovered apparatus, including means for blanking and cupping the flat metal stock into individual cups; means for drawing and redrawing the cups and bottom profiling them in one machine; and additional means for trimming, flanging, and beading the containers thus drawn. The system and method include, among other things, the utilization of apparatus which permits drawing, redrawing, and bottom profiling to take place in one press. This is accomplished by carrying draw, redraw, and bottom profile tooling in a single press and by inserting the cups in the press for the draw operation and then removing them and reinserting them for the redraw and bottom profile operations. The apparatus which makes it possible to perform the method in this fashion includes draw tooling; a first accumulator/divider table for feeding cups into the press and into the draw tooling; redraw and bottom profiling tooling; further apparatus for transferring the drawn cups from the press to a second accumulator/divider table and back into the press for the redraw and bottom profile operations. A further unique feature of the present system and apparatus is the disposition of the draw and redraw tooling within the press in alternating, balanced condition so that, in cooperation with the second accumulator/divider table, the press is at all times provided with a balanced load.

摘要： A method of forming container end panels from a sheet of material includes inserting the material into a press at a first level, blanking the material at that level, passing the material through a die and preliminarily forming it in a continuous stroke but at a second level and transferring it laterally at the second level for reforming and curling. The apparatus includes blanking and forming tooling at a first station and reforming and curling tooling at second and third stations. The reforming and curling tooling is disposed at the second level and the first, second and third stations are interconnected by an endless, apertured belt also disposed at the second level. An alternative embodiment involves disposing the first station tooling at an angle with respect to the press centerline, feeding the material into the press in a first direction and moving the preliminarily formed ends in opposite directions normal to the feed direction to second and third stations disposed on opposite ends of the press.

摘要： A method of forming container end panels includes first forming the bottom outer panel and then preliminarily forming the chuckwall and countersink radius by pulling material from the peripheral edge area with a punch core. The countersink radius is finally formed by partially retracting the punch core from the radius while holding the chuckwall to wrap some of the material in the radius upwardly. The apparatus includes an outer punch core with a tapered nose which preliminarily forms the chuckwall and countersink radius and then is retractable from the radius while holding the wall during final forming of the radius.
