Scrap metal baling press / guillotine shears
REPKON

Shear Forming from a a flat blank produces a cone with a uniform wall thickness that adheres to the sine law. Wall thickness is equal to the thickness of the original blank multiplied by the sine of one-half the included angle at which the cone is formed. Shear forming is done in a single pass of the rollers, eliminating the need for annealing. The finished diameter is virtually identical to the starting diameter. This reduces material requirements. With reductions in thickness, the need for machining is often reduced. But shear forming is limited to producing conical parts with uniform walls.

Repkon shear forming machine produces high precision conical parts with maximum diameter of 350 mm, maximum length of 550 mm and thickness tolerances on the range of ± 0,01 mm. Repkon shear forming machine employs two forming rollers each mobilized by a ball screw and servo-motor. The precision is enabled by readers behind each roller that can determine position to the micron levels.
