Abstract
A pair of female die parts are mounted on a table of a lower frame of a folding press for forming a folding groove. One of the female die parts is slidably adjustable on the table with respect to the other female die part by an adjusting device including pairs of first and second tapered shims. The first and second shims of each pair are slidably arranged with respect to each other. The first shims are coupled with the adjustable female die part and the second shims of each pair are coupled with an actuating member connected to a driving device for adjusting the position of the second shims with respect to the first shims.
Claims13
A tooling for a folding press for air folding comprising
- a male die and a female die, the female die including two parts mounted on a table of a lower frame of said press for forming a folding V and arranged to allow modification of a width of the folding V by moving of at least one of said two parts, and
- separating means including a spring steel blade including two longitudinal sides and arranged inside said folding V between said parts for separating said two parts, said longitudinal sides of the blade being secured to each of the two parts, respectively.
A tooling for a folding press comprising:
- a male die and a pair of female die parts mounted on a table of a lower frame of said press for forming a folding groove,
- at least one of the female die parts of said pair being slidably adjustable on said table with respect to the other female die part by an adjusting device allowing adjustment of a width of said folding groove,
- said adjusting device comprising a plurality of pairs of first and second tapered shims,
- said first and said second shims of each pair being slidably arranged with respect to each other,
- said first shims of each pair being coupled with said adjustable female die part and at least said second shims of each pair being coupled with an actuating member connected to a driving device for adjusting the position of said second shims with respect to said first shims,
- elastic means for acting on said adjustable female die parts for urging the same against the action of said tapered shims.
