UNIFY THREAD ROLLING

Specially designed for tubular processing. Equilateral triangle supports running to assure the roundness. Equilateral triangle supports rolling for improving roundness, concentricity and vertical degree. Driving by hydraulic unit: Featuring in easy operation and powerful pressure. The transmission gear with grinding shape: Featuring in noise-free, durable and precise transmission. Particularly applied to the tubular thread processing, such as oil connectors, bicycle, automobile and motor vehicle parts, radiating pipe etc.

UM-16 Thread rolling machine is setting with the vibration bowel. The working pieces are feeding to the between of the two thread rolling dies, after the thread rolling process, the working pieces are automatically loading off from the UM-16 thread rolling machine.

The robotic arms are setting in the between of UM-50A thread rolling machine.

UM-16 hydralich thru feed thread rolling machine set with the long bar feeding syste, this say up-grade the capacity, and save the labor cost.

UM-3D set with the vibration feeding bowl which is suitable for thread rolling set screws, wooden thread screws, and any less short screws are suitable. It is a very good method for saving labor cost.

The superior tool steel is a very important element of thread rolling dies. SKD11 (JIS) and 1.2379 (DIN) are the named raw material which we have chosen for the past years. The blank of thread rollingd ies are heat treated by Japanese TECHNO vaccum & oil quenching furnace by heat treating dep. (TOYOGEN INDUSTRIAL CO.,) It will render the higher rigidity and higher wear-resistance of thread rolling dies. After the heat tratment progress, the thread rolling dies are ground by Swiss REISHAUER thread grinding machines. And another progress of tempering to reduce the grinding stress is necessary for thread rolling dies. The thread rolling dies are ready for sale after the quality exam. The good quality of thread rolling dies is able to offer higher precision, longer working life, and reduced the cost to customers. We also produce the thread rollingd ies for other brands thread rolling machines. Your special specifications and requirements are very welcomed.

In feed (Plunge) thread rolling dies: There are multiple starts (helix angle) at the edge of thread rolling dies. The type of thread rolling dies are sutiable to thread rolling of shorter length. the thread rolling progress as: Place a work piece in between of thread rolling dies, the screws are formed by strongly pressing progress, when the right thread rollign die returns, take out the work piece. (the work piece stays at the same rollng point). Thru feed thread rolling dies: The threads are as the rings on the surface of thread rolling dies. The type of thread rolling dies are sutiable to thread rolling longer length of screws. (longer then the length of thread rolling dies) The threading progress as: Set the helix angle with the roller shafts of thread rolling machines first, and insert the thread rolling dies. 1. Place a work piece in between of thread rolling dies, make sure the work piece is clamped by thread rolling dies. 2. The work piece is moving

Specification: There are 2 producion methods of producing the proflie of thread rolling dies: Cutting method: is the traditional way for producing the thread shape of thread rolling dies, the threads are cut by the lathe machine. The thread shapes are with flat tip and flat root. Grinding method: is the newly way of producing the thread shape of thread rolling dies, the threads are ground by the thread grinding machines, teh trhead shapes are with round tip and round root. Why we choose the grinding method for UNIFY thread rolling dies, please check the above for the reason. Currently, we have more then 10 units of REISHAUER thread grinding machines (Swiss made) in our factory. The thread rolling dies offered by UNIFY are always the grinding type. The higher level quality can be ensured!

In respect of rolling the serration type working pieces as the transmission shafts of autobobile/motor-vehicles, spline shaft, and manual tools. The grinding type serration spline rolling dies can be ensured for the precision, delicate and smooth surface, extending the life of the rollers.

The knurling die: The knurling pattern with non-skid and attracting in appearance on manual tools (straight knurling pattern or diamond knurling pattern) by the knurling dies. The knurling pattern is formed by gear hobbing machine before the heat treatment process, the precision is less good as the grinding type, but, the straightness, and concertricity can be assured.
