Gear precision forging processing technology: cold heading and hot precision forging

Gear precision forging processing technology: The descriptions of cold heading and hot precision forging are as follows, for reference.

1. Cold heading forging:

Also called occlusion forging, it is an advanced precision forming technology without flash.

When the mold tooth profile accuracy reaches level 6, under mass production conditions,gearThe accuracy can reach 8-9 levels.Such products can meet the requirements of trucks and light vehicles, and can be used in low-speed, heavy-duty, and high-noise working environments.

In the long-term use process, it is found that the failure mode of this kind of gear products, the ratio of tooth surface failure is higher than the ratio of tooth body failure, mainly wear and pitting.

2. Hot precision forging:

The mature hot precision forging process is called "one fire, two forging", that is, after the gear is formed and trimmed by hot forging, the residual heat of the forging is used for finishing, and the precision of such hot forged gears is about 8-9.

Precision forging technology and precision mold manufacturing technology have been widely used in the mass production of gear parts.The above description of gear precision forging processing technology is for reference only.
