Problems solved by technology

However, the flash edge needs to be followed by eager cutting; if the flash edge size is too large, the material utilization rate is low
[0005] For I-shaped forgings with complex shapes, especially those with large differences in shape and size, if the hot die forging process is used, large flashes will be generated along the cross-section of the forging, and material waste is serious; due to the complex shape of both ends, it is easy to cause dissatisfaction , Difficult pre-forging design
If the tire die forging process is used, the process is long and it is not suitable to organize mass production

Embodiment 1

[0043] Such as Figure 3 ~ Figure 7 As shown, this embodiment includes: an extrusion punch, an upsetting punch and a final forging punch that are evenly distributed on the circular formwork 1, and a die assembly that is concentric with the circular formwork 1 and rotates. Among them: three punches share a set of die components.

[0044] The circular mold base 1 is set on the body 20, the center O of the working punch coincides with the working center of the press, and can rotate relative to the body 20 with the center O as the center.

[0045] Such as Image 6 with Figure 7 As shown, the die assembly includes: an upper die 9, a lower die 10, and a cylindrical die cavity formed when the oblique slider 8 is closed; Four push rods 11 are housed in the 10, and the upper ends of the push rods 11 are fixed on the oblique slider 8, and the outer sidewall of the oblique slider 8 has a certain inclination and satisfies

[0046] In this embodiment, the outer wall of the inclined ...

Abstract

Disclosed are an H-shaped connector rotating die and a forming process thereof. The die comprises an extrusion punch, an upsetting punch and a finish forging punch circularly and evenly distributed on a round die set and a cavity component concentrically and rotationally arranged with the round die set, wherein the three punches share one set of the cavity component, the cavity component comprises an upper cavity, a lower cavity with a push rod and an inclined slider, and a cylindrical die cavity is formed when the upper cavity, the lower cavity and the inclined slider are closed. By the H-shaped connector rotating die and the forming process thereof, the problem that workpieces have to be taken out between the procedures of conventional multi-procedure forging is avoided, production efficiency is increased by times, cost per piece is lowered, and continuous batch production of the parts is realized.

Description

technical field [0001] The invention relates to a technology in the field of mechanical processing, in particular to a rotary mold for an I-shaped joint and a forming process thereof. Background technique [0002] The I-shaped joint is a non-standard special-shaped joint. There is a step in the middle rod, and the shapes of the heads at both ends are different. Due to the complexity of its shape, it is usually manufactured by casting. However, the quality of the joint parts produced by the casting process is complicated, and casting defects such as pores, shrinkage cavities and sand holes are easy to form; due to the casting structure, its mechanical properties are relatively poor, which affects the connection strength of the components. [0003] After searching the prior art, it was found that Chinese Patent Document No. CN101444816, published (announcement) date 2009.06.03, discloses a forging process for I-shaped parts. This technology forges a cylindrical blank into a re...
