This is one hot rolling 3 rolls thread rolling machine without hydraulic system , main motor: 22KW. This machine is widely used to make external thread of many kinds of railway spike screws. The workpieces have to be heated via Intermediate frequency heating furnace before rolling thread. Usually the thread pitch of these railway spike screws is 12.5mm.
There are 3 pcs thread rolling dies on the machine, an equilateral triangle will be formed after adjusting the thread, the pressure in three different directions on blank workpieces is very uniform, so the finished thread rods can maintain good concentricity, and the high precision is thus guaranteed too.
With the development of science and technology, the demand for automatic machinery in various factories is getting higher and higher. For this type hot rolling thread rolling machine. Our professional R&D team can design customized automatic feeder with manipulator, this enables the transfer of the heated workpiece from the intermediate frequency heating furnace to the thread rolling machine. The automatic feeder system can help factory to save cost and produce safely.
