The V type arm contains the tie rod and the oblique pull rod of mutual articulated setting, the intermediate position of oblique pull rod sets up the embedded groove, the cross axle at the stand lateral wall is worn to connect in the embedded groove endotheca, but oblique pull rod passes through the side at the stand of embedded groove and cross axle's cooperation slidable mounting.

And the positioning round rollers of the auxiliary die mechanism are arranged on the same outer side edge of the n-shaped arm.

The utility model has the advantages that:

the utility model discloses an assist traditional moulding-die actuating mechanism of mould mechanism cooperation and realize the rolling edge rolling integrated into one piece action of steel sheet, its oil consumption reduces, and the steel sheet shaping has good streamline degree. The utility model discloses a with conventional shaping oil pressure equipment's die holder replace become have carry out the supplementary mould mechanism of edge rolling effect to the steel sheet, it not only can produce the location to the door frame steel sheet to assist mould mechanism, and accessible n type arm, link gear such as V type arm is connected with conventional shaping oil pressure equipment moulding-die actuating mechanism, the shaping die head produces the arc bending processing to the door frame steel sheet down along with the mount pad, at this in-process, assist mould mechanism and be driven thereupon, the edge rolling is handled along the both sides of door frame steel sheet, thereby satisfy the rolling of door frame steel sheet, so that the steel sheet forms streamlined semiellipse circular structure, improve fashioned efficiency and effect.

Detailed Description

To facilitate understanding of those skilled in the art, the structure of the present invention will now be described in further detail with reference to the following examples:

referring to fig. 1-3, an oil pressure device for forming a steel plate of a tower doorframe comprises a die-pressing driving mechanism 1, wherein the die-pressing driving mechanism 1 comprises a hydraulic cylinder 12 fixedly connected below a portal frame 2, and a piston rod of the hydraulic cylinder 12 is provided with a forming die head 11 through a mounting seat 13; two sides of the pressing die driving mechanism 1 are symmetrically provided with auxiliary die mechanisms 4 through corresponding upright posts 3, and each auxiliary die mechanism 4 comprises an n-shaped arm 43 which is sleeved on the outer side of each upright post 3 and is rotatably connected with the upright post 3; the open end of the n-shaped arm 43 is arranged at one side of the die driving mechanism 1, and the closed end thereof is arranged at one side of the upright post 3; two positioning round rollers 41 are arranged at the open end of the n-shaped arm 43 in a vertically staggered manner; the positioning round rollers 41 extend to any outer side edge of the n-shaped arm 43; the closed end of the n-shaped arm 43 is hinged with a V-shaped arm 42, and the end of the V-shaped arm 42, which is not hinged with the n-shaped arm 43, is hinged on the side of the mounting base 13.
