Thread processing is a key link that determines the assembly accuracy and service life of fasteners. In high-end fastener manufacturing, precision thread rolling machine has completely replaced traditional thread cutting technology, becoming the key supporting equipment matching cold heading machine, cold forging machine and screw making machine in the fastener production line. Relying on cold rolling molding technology, the equipment realizes high-precision thread processing, solving the problems of low precision, poor surface quality and easy thread damage in traditional cutting processes.
The working principle of the thread rolling machine is to use the plastic deformation characteristics of metal materials to roll and form threads through precise die extrusion. This processing method does not cut metal fibers, making the thread surface denser, smoother and more wear-resistant. The equipment can control the thread medium diameter tolerance within ±0.02mm, and the surface roughness is as low as Ra0.4μm, which is far superior to the precision standard of traditional cutting processing. The processed threads have tight fit, low friction loss and stronger bearing capacity, meeting the strict quality requirements of automotive parts, aerospace, precision electronics and other high-end fields.
In terms of production efficiency and economy, thethread rolling machine has outstanding comprehensive advantages. It supports continuous automatic feeding and rolling, with fast molding speed and no waste generation in the processing process. Matched with the front-end screw making machine and cold heading machine, it forms a fully automated fastener production line from blank forming to thread finishing, greatly reducing manual intervention and labor costs. Compared with traditional processing lines, the integrated production mode improves overall production efficiency by more than 30% and effectively shortens the production cycle of customized fasteners.
