Abstract
A compact, portable metal forming device comprising: 1) a frame having entry and exit ends; 2) guide means adjacent the entry end for guiding a sheet of metal to be formed to a hand operated drive assembly supported within the frame that engages the metal sheet and drives it, through the operation of a series of gear linked separately journaled forming roll pairs mounted in the frame, 3) adjacent the exit end an adjustable cam wheel that engages one edge of the metal sheet and forms that edge just prior to the metal sheet reaching the exit end, and 4) forming the exit end, a guillotine cutter including a shaped exit aperture for cutting the formed metal sheet to any selected length.
Claims8
A compact, portable sheet metal forming apparatus comprising:
- A) a frame having an entry and an exit end and opposing sides;
- B) an internal frame formed by the insertion of a downward extending flange between said opposing sides;
- C) parallel, offset slotted guide bars extending outwardly from said entry end that guide sheet metal to be formed;
- D) a series of at least two forming roll pairs arranged to receive said sheet metal from said guide bars comprising:
- I) a forming roll mounted on a shaft having first and second ends journaled in said opposing sides;
- and
- II) a drive roll mounted on a shaft having first and second ends, said first end journaled in said downward extending flange and said second end journaled in one of said sides;
- E) a handle attached to said first end of one of said forming roll shafts;
- F) interlocking gears attached to said second ends of said forming roll and said drive roll shafts drivingly connected with each other;
- G) interlocking transfer gears mounted on shafts journaled in said one side in which said second ends are journaled and drivingly engaging at least one of said interlocking gears of each of said forming roll pairs;
- H) downstream of said at least two forming roll pairs, proximate one of said side walls an adjustable edge forming assembly comprising:
- I) a cam wheel;
- and
- II) a guide roll facing said cam wheel;
- and
- I) a guillotine cutter forming said exit end for selectively cutting custom lengths of sheet metal formed in said metal forming apparatus.
