The thread rolling machine is a kind of multifunctional cold extrusion forming machine tool that can perform a series of treatments to workpieces in cold state. By using it, the wrokpieces can be rolled with whorl, straight grain or cross grain, or with straight tooth, helical tooth or oblique spline tooth. In addition, it is also capable of alignment, hole shrinkage, barreling and other types of rolling shaping.
1. The whorl cold rolling craft is remarkably advanced and free from machining, which can dramatically improve the intrinsic and apparent quality of workpieces.
2. This thread rolling machine mainly utilizes the rolling tool for extrusion forming. As the metal fiber of tool is consecutive, the produced radial stress can greatly enhance the surface smoothness, rigidity and strength of workpieces. The working efficiency is several times or even dozens of times higher than that of machining work. Meanwhile, this craft saves more materials and is easier to realize automatic processing.
3. The produced radial stress can observably enhance the fatigue strength and torsional strength of workpieces. Hence, this is really a high-efficient, energy-saving and low-consumption processing craft.
4. All the models are our newly and independently developed patented products.
The ATR16 non-hydraulic thread rolling machine is a dedicated device for processing the harness cord (whorled rod) with the specification of 4 to16mm diameter. Especially for processing fixed whorls, the working efficiency will be multiplied. In the meantime, the defect of hole shrinkage is avoided and the workpiece quality is well ensured. This product is widely applied to machinery installation, keel decoration, air-conditioning facilities, communication device mounting and other fields.
This equipment is applicable for rolling forming the workpiece with 4 to16mm diameter and with straight grain, spiral grain or cross grain in cold state. After configured with cylindrical die rolls, it can process fixed whorls and harness cords. Welded with steel plates, this product features rational structure, easy operation and reliable quality. It is the ideal choice for producing non-standard whorls and standard bolts.
The TR150 thread rolling machine is deeply favored by customers by virtue of solid structure, superior craft, easy maintenance and reasonable price. It enables both radial and axial processing and can process common bolts, abnormal bolts and harness cords after configured with cylindrical die rolls. The harness cords produced by this equipment in production base of Zhejiang have been exported to America, Canada, Europe and other developed countries.
With rational and sturdy structure, the TR160 mainly features large power, small noise, low failure rate, convenient adjustment, high accuracy and wide application range. It can process common, trapezoidal and modular whorls, and it is also capable of forming, barreling, knurling and rolling processing.
It adopts worm gear, worm drive and automatic lubrication system. The available manual, foot switch, semi-automatic and automatic control modes allow for more convenient operation. In addition, it has high production efficiency and low labor intensity. Working with cylindrical die rolls, it can process common and abnormal bolts of various specifications.
The TR200 thread rolling machine is primarily used for processing various precise external whorls and high-strength standard workpieces, including common, trapezoidal and modular whorls. The applicable materials contain the carbon steel, alloy steel and the non-ferrous metal whose ductility is more than 10% and tensile strength is less than 100kgf/mm2.
The TR630 thread rolling machine is used to process various kinds of precise external whorls as common, trapezoidal and modular whorls. It is also able to process round workpieces with forming, aligning, barreling, knurling and rolling treatments. The workable materials should be the carbon steel, alloy steel and the non-ferrous metal with over 10% ductility and the tensile strength of less than 100N/mm2.
