Claims

[Scope of utility model registration request]

Consisting of an upper mold and a lower mold, at least one of which has a bent shape of the workpiece and is movable up and down, and two parts arranged on the left and right sides of either the upper mold or the lower mold so as to be able to come into contact with and separate from the one mold, Both inner sides have a shape that forms the required shape after processing with an upper mold and a lower mold,
Both outer sides have a side push mold with an inclined shape, and the inside has inclined parts corresponding to both outside sides of the side push mold, and a wedge member arranged so as to be movable toward and away from both outside sides of the side push mold, and a wedge member that is movable up and down. It is characterized by comprising a drive device for moving the mold, a drive device for moving the wedge member, an approach angle changing device for changing the approach angle of the side-pressing mold with respect to the one mold, and a moving device for moving the device body. Pipe bending press equipment.
