Embodiment Construction

[0073] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0074] In the forming apparatus 1, on a base 2, a driving device 4 and a forming stage 3 are arranged facing each other. The forming table 3 is equipped with at least a pair of forming rolls or a pair of forming dies.

[0075] The driving device 4 is provided with a driving rod 5. The driving rod 5 is driven by a driving source not shown, and moves forward and backward in a direction (arrow 50) approaching the forming stage 3 and a direction away from the forming stage 3 (arrow 51). The drive rod 5 is provided with a material support mechanism 6 to be formed at the front end on the side of the forming table 3.

[0076] In this forming apparatus 1, a to-be-formed material 11 (such as a metal pipe) is pressed by a to-be-formed material support mechanism 6 ( image 3 ), the end ( image 3 The right end of the center), the drive rod 5 is moved in the direction approach...

Abstract

Provided is a forming apparatus capable of shaping a shaping object by an extroll-forming method and a draw bench method. On a platform, a driving device and a shaping stand having at least one pair of shaping rolls or at least one pair of shaping dies are arranged to confront each other. The driving device includes a drive rod moved by a drive source forward and backward to approach and leave the shaping stand and having a shaping object supporting mechanism at the leading end on the side of the shaping stand. By the shaping object supporting mechanism, a shaping object is pushed at its end on the side of the driving device so that the drive rod is moved in the direction toward the shaping stand thereby to push the shaping object into the clearance of the shaping rolls or the shaping dies. Alternatively, by the shaping object supporting mechanism, a shaping object is gripped at its end on the side of the driving device so that the drive rod is moved in the direction away from the shaping stand thereby to extract the shaping object from the clearance of the shaping rolls or the shaping dies.

Description

Technical field [0001] The present invention relates to a forming apparatus for forming a material to be formed such as a metal pipe using a forming roll or a forming die. In particular, it relates to a forming device suitable for forming various metal pipes with cross-sectional shapes into special-shaped pipes with different cross-sectional shapes, and reducing the diameter of various metal pipes. Background technique [0002] As a forming apparatus that drives a forming roll to form a material to be formed, a roll forming apparatus is known. On the other hand, as a forming apparatus for forming a material to be formed using a non-driven forming roll, a squeeze roll forming apparatus is known. In addition, as a forming device for forming a material to be formed using a non-driven forming roll and a mold, a drawing device such as a drawing machine is known. [0003] As a conventional squeeze roll forming device and drawing device, there is known a device in which a driving device...
