Market Need: Efficiency Gains in Bolt Threading
Rising demand for high-strength fasteners in heavy machinery and metallurgy applications is placing intense pressure on bolt manufacturers. Traditional thread cutting methods often struggle to keep pace with required throughput while maintaining consistent thread geometry. Category managers report that scrap rates, downtime, and labor costs related to older threading equipment are eroding margins. A shift toward automatic cold-forming processes is emerging as the most direct route to higher productivity and better part quality.
For shops producing bolts in the 5mm to 36mm diameter range, the need for a robust, energy-efficient thread rolling solution is acute. The Bar Bolt Thread Rolling Machine from Xingtai Qiangqi Machinery Manufacturing Co., Ltd. addresses this gap by combining automatic operation with eco-friendly features and fast cycle times—helping buyers meet delivery targets without compromising on precision.
Product Description: Built for Continuous Thread Rolling
The Bar Bolt Thread Rolling Machine is a steel-constructed, floor-standing unit designed for high-volume manufacturing environments. Its core components—an engine, gear set, gearbox, motor, and bearing assembly—are selected for reliability under repeated heavy loading. The machine operates on a 380V power supply (customizable voltage) and draws 4KW, balancing energy efficiency with the force needed to form threads through cold rolling.
At the heart of the process are rollers with diameters ranging from 5mm to 36mm, enabling a broad spectrum of bolt sizes. A 54mm shaft diameter and a maximum rolling pressure of 140 KN ensure adequate force for forming threads on medium-carbon and alloy steels. The dynamic spindle feed speed of 5mm/s, combined with spindle speed options of 39, 49, 66, or 82 revolutions per minute, allows operators to fine-tune parameters for different material grades and thread pitches. The machine achieves a line speed of 3 to 6 meters per minute, translating to a production capacity of 1/10 seconds per piece—a significant leap over manual or semi-automatic alternatives.
Automatic control reduces operator intervention, lowering the risk of inconsistent thread profiles. An eco-friendly design minimizes energy waste, while the compact footprint—1350×1210×1050 mm—saves valuable shop floor space. At 3000 KG, the machine’s mass contributes to stability during high-speed rolling, further enhancing thread accuracy.
