Description

Technical Field

[0001] This utility model belongs to the field of metal fastener processing technology, specifically relating to a thread rolling machine for metal fastener thread forming. Background Technology

[0002] Metal fasteners are a general term for mechanical parts used to fasten two or more parts (or components) together into a single unit. They are typically made of metallic materials, such as steel, aluminum, and copper, but can also be other metal alloys. Metal fasteners are widely used in various industries and fields, such as machinery, construction, electronics, and automobiles. The main types of metal fasteners include bolts, studs, nuts, and washers. Bolts, studs, and nuts require thread rolling during the manufacturing process to form threads.

[0003] Existing thread rolling machines for metal fastener thread forming still have some shortcomings. Most thread rolling machines require manual adjustment of the distance between rollers when processing threads on objects of different specifications and sizes, resulting in poor debugging time and wasting time and effort. Therefore, we propose a thread rolling machine for metal fastener thread forming. Utility Model Content
