How to Use a Hossfeld Bender
The Hossfeld metal bender bends tubular material, flat iron, angle iron, and roll stock. Many shapes and configurations can be formed with the use of a variety of dies. The bender can be operated manually or with a hydraulic system. The set-up times for different jobs and applications vary, but with practice, the operator can move from material to material or from thickness to thickness with little lost time or material.

How to Use a Hossfeld Bender to Bend Tubular Material
-
1
Mount the back block, numbered-side up, on the left-hand steel arm with the U-pin. The long leg of the U-pin should pass through the hole number on the steel arm corresponding to the number on the back block, and through the back block. The short arm of the U-pin should face away from the pivot point.
-
2
Mount the draw block, numbered-side up, on the right-hand steel arm with the eye pin. Insert the eye pin in the hole on the steel arm with the number corresponding to the number on the draw block.
-
-
3
Mount the form die, numbered-side up, at the pivot point between the two steel arms with the center pin. The straight edge of the form die should be parallel to the back block.
-
4
Move the two steel arms toward each other to form the smallest angle possible between them. Adjust the back block and the draw block until they are in a straight line.
-
5
Insert the tubing material between the back block and the forming die, aligning the mark on the forming die with the point on the tubing where the bend is to start. Pull on the right-hand steel arm to bend the tube around the forming die. The amount of pressure applied to the steel arm will determine the amount/angle of bend on the tubing. If more bend is desired than achieved on the first pull, reposition the tubing between the back block and the forming die, and pull on the steel arm again.

Insert the center pin with the small end up at the pivot point between the steel arms. Insert the U-pin with the long arm through the second hole on the left-hand steel arm and the short arm toward the pivot point. Place the U-pin roller on the short arm of the U-pin.

7
Insert the eye pin into the sixth hole on the right-hand arm. Insert the flat head pin into the first hole on the right-hand arm.

8
Screw the thumb nut onto the eye bolt bending dog. Place the long slot of the eye bolt bending dog over the flat head pin, making sure that the indented side of the flat head pin faces the longer side of the bending dog. Place the threaded end of the bending dog into the eye pin.
-
9
Move the two steel arms toward each to form the smallest angle possible between them. Place the rod stock between the center pin and the end of the bending dog about 1/8-inch from where the bend is to begin to allow for the rod to be drawn into the bender as the bending takes place. Tighten the thumb nut against the eye pin to hold the rod stock securely.

Insert the center pin with the small end up at the pivot point between the steel arms so that the pin sticks up about 1½ inches. Insert the U-pin with the long arm through the third hole on the left-hand steel arm and the short arm toward the pivot point.
-
12
Insert the eye pin through the last hole on the right-hand steel arm. Insert the flat head pin through the second hole on the right-hand steel arm

Screw the thumb nut onto the eye bolt bending dog. Place the long slot of the eye bolt bending dog over the flat head pin, making sure that the indented side of the flat head pin faces the longer side of the bending dog. Place the threaded end of the bending dog into the eye pin.
-
14
Place the caster fork bending die (must be purchased from Hossfeld) on top of the center pin. Move the two steel arms toward each to form the smallest angle possible between them. Place the flat bar stock between the caster fork bending die and the eye bolt bending dog, lining up the place where the bend is to begin with the end of the eye bolt bending dog. Tighten the thumb nut against the eye pin to hold the bar stock securely.
-
15
Pull on the right-hand steel arm to bend the bar to the desired angle.

Tips & Warnings
Store each bending die set together. The parts are not interchangeable. Put a little wax or grease on the draw block before bending the material. Do not get wax or grease on the back block or form die.
