Die sets F250-F251 and F252-F253 are recommended for 18 gauge and lighter because of the side thrust on punch caused by tipped forming angle.
Die set F250-F251 has a tipped forming angle to minimize sheet whip up and provide ram clearance on deep channel forming done in two strokes.
F252-F253
Die sets F250-F251 and F252-F253 are recommended for 18 gauge and lighter because of the side thrust on punch caused by tipped forming angle.
Die set F252-F253 has tipped angle to strengthen gooseneck caused by clearance required for deep return flange.
F254-F255
Die set F254-F255 forms three bends in one stroke. Consult our engineering department for tonnage requirements.
F256-F257
When flange on 90 degree bend is too short to permit forming on standard vee dies, die set F256-F257 is recommended. Forming angle is tipped and dies are heeled to prevent spreading.
F300-F301
In making rectangular tubes, die sets F300-F301 are often used as a progressive combination. A slight curvature can be expected on the formed side but, whether it is convex or concave , can be controlled in the forming.
F302-F303
Die set F302-F303 has its own locating gauge so the operator does not have to hold the part during the closing operation. This gauge also prevents the part from slipping out of the dies. With metals having large springback, the closed edges will open considerably. If the seam is to be welded closed, a welding jig or fixture will be necessary.
