Introduction about the thread rolling machine




   Our thread rolling machines are widely used  in construction and auto spare parts. It can  process screw thread/ general bolt/ heterogenic bolt and gear rack under the cold-hobbing station. It's designed with the advantage of high-efficiency,energy-saving and low-consumption. The machine equipped by the frame,transmission box,fixed spindle foundation,movable spindle foundation, tailstock hydraulic system and the electrical parts.





Functions about the thread rolling machine




     Thread rolling machines are used to produce high quality screws and other small tools and components. They are ideal for high volume production, are highly economical and ensure excellent dimensional accuracy. We are a well known hydraulic machines manufacturer, supplier and exporter of Hydraulic Rolling Machines-Two Roll Types, Hydraulic Rolling Machines-Three Roll Types, etc. These hydraulic machines are ideal for mass production purposes and help in creating the best surface finishes.

    The machine  is mainly used for processing precision standard parts of external thread and high strength, including regular thread, trapezoid thread and modulus thread.  It also can process the workpieces by shaping, straightening ,tumbling and threading.

    The objective material to be processed including carbon steel, alloy steel and nonferrous metal with elongation over 10% and tensile strength less than 100kgf/mm2.




Features about the thread rolling machine





  The driving axis is enlarged and lengthened, the main motor is 5.5kw, the transmission box has big power and high efficiency.This machine applies to produce trapezia thread bolt and clamping screw.




1.  Machine tool is welded with steel plate which is very durable during using .


2.   Rolling wheel is consist of hard alloy, it can change according to your needs.


3.  Sliding parts after manual grinding, improve the machining precision.


4.   Hydraulic system uses high-quality gear pump, supplying machine oil, lubricating and cooling the machine automatically.


5.  With high quality motor,make the machine perfect.


6.  Power distribution box with high quality gear which through high frequency quenching, make the machine durable. 


7.  Distribution gear with the hollow design, make no longer restricted the length of the   screw,the length of screw is unlimited in theory.


8.  Have Time Relay, reduce the labour, make the screw thread having a high consistency.


9.  By using thread roller machine, the rebar can be processed with straight threads. After processing , the compressive strength of rebar can be improve 20%-30%, the fatigue resistance can be improve 40%-60%, the resistance to corrosion can be improved 50%-200%.


10.  One year warranty and lifelong tenure technical guidance.
