Abstract

A rotary forming apparatus of the type having a pair of central rotors, and one or more die carriers swingably mounted on the rotors, for repeatedly forming a sheet metal work piece moving along a linear path, rotor bearing supports for supporting the rotors at least at one end thereof, die carrier guides on the die carriers at an end thereof adjacent to the rotor bearing supports, and, at least two cam plates adjacent to each the rotor bearing support, for guiding the die carriers guides.

Claims (18)

1. A rotary forming apparatus of the type having a pair of rotors, and one or more die carriers swingably mounted on the rotors, for repeatedly forming a sheet metal work piece moving along a linear path, and comprising;
rotor bearing supports for supporting the rotors at least at one end thereof;
die carriers on said rotors;
die carrier guides on the die carriers at an end thereof adjacent to said rotor bearing supports;
at least two cam plates adjacent to each said rotor bearing support, at said at least one end, for guiding said die carriers guides , and, gates in the cam plates for passage of said die carrier guides.
2. A rotary forming apparatus as claimed in claim 1 , wherein there are two such rotor bearing supports, one at each end of rotors and wherein said cam plates are mounted on one of said bearing supports, the other of said bearing supports being tree of such cam plates.
3. A rotary forming apparatus as claimed in claim 1 in which the cam plates comprise at least a first integral one piece cam plate, and a second cam plate of at least two part construction, said second cam plate defining a gate, through which said die carrier guides may pass.
4. A rotary forming apparatus as claimed in claim 3 wherein the die carriers define leading and trailing edges, and including die carrier guides on at least one said leading edge and one said trailing edge.
5. A rotary forming apparatus as claimed in claim 4 wherein said gates receive said leaning edge die carrier guides.
6. A rotary forming apparatus as claimed in claim 1 wherein the rotors are driven by a variable speed motor, and including control means for slowing and speeding up said motor intermittently, in timed relation to the movement of the sheet metal work piece.
7. A rotary forming apparatus as claimed in claim 3 wherein said second cam plate comprises a generally oval shaped cam portion and a semi arcuate cam portion spaced from said oval shaped portion, and a guide channel defined between said oval portion and said semi arcuate portion.
8. A rotary forming apparatus as claimed in claim 7 wherein said semi arcuate portion defines two ends, and wherein said gates are defined between said ends of said semi arcuate portion and said oval shaped portion.
9. A rotary forming apparatus as claimed in claim 8 wherein said semi arcuate portion defines an outer guide surface for contact with said trailing edge guides.
10. A rotary forming apparatus as claimed in claim 9 wherein said semi arcuate portions, further comprise guide bar portions for receiving both said leading and trailing edge guides.
11. A rotary forming apparatus as claimed in claim 4 wherein said leading edge guides are offset outwardly relative to said trailing edge guides.
12. A rotary forming apparatus as claimed in claim 11 wherein said leading edge guides are mounted on shafts, and including rollers rotatably mounted on said shafts between said leading edge guides and said die carriers.
13. A rotary forming apparatus as claimed in claim 1 wherein the motor control is operable to speed up the motor at a first predetermined position of said die carriers, and slow down the motor at a second predetermined position of said die carriers, and thereafter speed up the motor at a third predetermined position of said die carriers, and thereafter to slow down said motor.
14. A rotary forming apparatus as claimed in claim 1 wherein there are two such rotors each rotor defining a first end and second end, and a bearing support supporting the first end of each said rotor, the second end of each rotor being unsupported, and the two rotors being mounted for rotation in opposite directions to one another, for engaging a sheet metal work piece passing there between.
15. A rotary forming apparatus as claimed in claim 1 wherein there are a plurality of die carriers and a plurality of such rotors.
16 A method of forming a sheet metal workpiece by passing it between two rotors, each said rotor carrying at least one die for forming said sheet metal and comprising the steps of;
rotating said rotors in opposite direction at a predetermined first speed of rotation;
speeding up said rotors at a first predetermined position ;
progressively slowing down said speed of rotation until a second predetermined position;
progressively speeding up said speed of rotation until a third predetermined position, and, thereafter slowing down said speed of rotation to said predetermined first speed.
17 The method as claimed in claim 16 and wherein said first predetermined position is at a point just prior to contact of said dies with said sheet metal and said third predetermined position is at a point just after separation of said dies from .said sheet metal.
18 The method as claimed in claim 16 and wherein said dies are attached to die carriers, and wherein the die carriers are swingably mounted on respective rotors, and including the steps of guiding the die carriers as the rotors rotate and bringing said dies thereon into planes parallel with one another at said first predetermined position, and maintaining said dies in said parallel planes until said predetermined third position.
