Embodiment Construction

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

[0074] In the forming apparatus 1 , a driving device 4 and a forming stand 3 are arranged to face each other on a base 2 . The forming stand 3 is provided with at least one pair of forming rolls or a pair of forming dies.

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

[0076] In this forming apparatus 1, a material to be formed 11 such as a metal pipe is pressed by a material to be formed supporting mechanism 6 ( image 3 ), on the side of the driving device 4 ( image 3 The right end in the center), the driving ...

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 device 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 shaping various metal pipes into different cross-sectional shapes for special-shaped pipe forming, and for reducing the diameter of various metal pipes. Background technique [0002] A roll forming device is known as a forming device for forming a material to be formed by driving forming rolls. On the other hand, a squeeze roll forming device is known as a forming device that uses non-driven forming rolls to form a material to be formed. In addition, drawing devices such as drawing machines are known as forming devices that use non-driven forming rolls and dies to form a material to be formed. [0003] As a conventional squeeze roll forming device or drawing device, a driving device and a forming stand provided with at least one pair of forming roll...
