It is generally used in mining machinery, bridges, automobiles, motorcycles, boiler steel structures, tower cranes, large-span steel structures and large buildings.

[0003] The traditional thread rolling method generally uses two thread rolling plates to roll the screw. Each thread rolling plate is provided with two threaded parts for realizing one-time forming of double-start threads. In order to improve the thread rolling effect, tapping oil is continuously added during thread rolling. The existing technology generally uses a pump body to supply oil, which increases the cost of the device. A separate program needs to be designed to supply oil when the thread rolling plate moves down and not supply oil when it moves up. In addition, the surface of the screw after processing will be stained with more oil, and subsequent processing is also more troublesome. Utility Model Content
