AI Technical Summary
Technical Problem
Existing thread rolling dies are ineffective at machining the threads of combined screws in the areas where spring washers and flat washers are fitted, resulting in material waste and installation inconvenience.
Method used
Design a thread rolling plate with an inclined notch and a feed notch. The inclined notch gradually squeezes the spring washer, and combined with the pushing mechanism, it realizes the thread processing of the combined screw, avoiding the spring washer and flat washer from separating during the processing.
Benefits of technology
It enables efficient machining of combined screw threads, saves costs, ensures the stability of spring washers and flat washers during machining, extends the service life of thread rolling, and improves installation efficiency.
