fig. 2 is a schematic diagram of the triangular molding of the pipe fitting of the present invention.

Detailed Description

The utility model is further described with reference to the following figures and examples.

As shown in fig. 1, the pipe fitting triangular forming device of the present invention includes an upper fixing plate 1, a mandrel guide sleeve 2, a mandrel 3, a forming member, a part guide seat 4, a lower mold wrapping block 5, and a lower bottom plate 6.

The lower die wrapping block 5 is fixedly connected to the lower bottom plate 6, three forming components are arranged in the lower die wrapping block 5, parts to be formed and the core rod 3 are connected through the part guide seat 4, and the upper end of the core rod 3 is connected with the upper fixing plate 1 through the core rod guide sleeve 2.

The three forming parts are distributed in trisection according to the forming surface. The part guide base 4 is in a triangular shape. The core rod 3 is a triangular core rod.

Each forming part consists of a forming rib plate 7, an inclined push block 8, an inclined punch 9, a push block guide block 10, a tension spring limiting block 11, a tension spring 12 and a tension spring bolt 13. A push block guide block 10 is connected respectively to shaping gusset 7 bottom both sides, and shaping gusset 7 is connected to the front end, and extension spring bolt 13 is connected to the rear end, and extension spring bolt 13 is connected with lower mould parcel piece 5 through extension spring stopper 11, is equipped with extension spring 12 between extension spring bolt 13 and the

extension spring stopper

11, and 8 tops of oblique push block are equipped with oblique drift 9, and oblique drift 9 upper end fixed connection is on upper fixed plate 1.

The core rod 3, the forming rib plate 7 and the part guide seat 4 all need a surface titanium plating process, so that the smoothness and the use hardness are increased, and the service life is prolonged.

The whole pipe fitting three-edged forming device needs the lower die wrapping block to fix the outside stress at last, and the forming stability of the mechanism is improved.
