High Quality Thread Rolling Machine

The Hydraulic 2 Roll Thread Rolling Machine by T.L. Pathak Group is a precision-engineered device designed for efficient thread rolling on various materials, including steel, aluminum, and brass. This advanced machine employs hydraulic power for smooth and consistent operations, ensuring high-quality thread formation with exceptional accuracy. Featuring robust construction, the machine is built to withstand rigorous industrial use while maintaining low maintenance requirements.

The two-roll configuration enables the production of precise and uniform threads by exerting symmetrical pressure on the workpiece, enhancing durability and strength. It is equipped with a user-friendly control system that allows for easy adjustments and monitoring, ensuring optimal performance and minimal downtime. The machine supports a wide range of thread sizes and pitches, making it versatile for diverse applications in automotive, aerospace, and manufacturing industries. Additionally, the T.L. Pathak Group's commitment to innovation and quality ensures that this thread rolling machine delivers reliable and efficient performance, meeting the demands of modern production environments.

Compared to other thread manufacturing methods, thread rolling machines offer the following advantages:

Standard equipment is represented by equipment for rolling a hydraulic type thread with transverse feed and feed to the passage.

Accuracy

High-precision thread rolling is available. (JIS 4h)

Versatility

General screw, left-handed screw, multiple thread screw, worm, knurl, serration, pipe-thread and burnishing can be manufactured.
Furthermore, stem-shaped workpieces can be processed.

Power

With high rolling pressure, any malleable material can be processed.

Space and Energy Saving Design

Compact machine size and simple and highly efficient drive system provide space and energy saving operation.

The sliding base plate is thickened, with the thickness increased by about 40% compared to the original, making it more stable and durable. The top part is made of ductile iron casting. The sliding track uses tapered strips and a dovetail structure, making the slide rail more stable and durable during operation.

This tool uses a worm gear to adjust the stroke, which can achieve fine adjustment of the thread depth during workpiece processing. The handwheel only adjusts 0.2mm with one full rotation, while the original one adjusted 3-6mm with one rotation, a difference of 15-30 times in adjustment accuracy. The adjustment of the mold distance is very rough, and if the thread depth is slightly different, it is difficult to adjust. Either it is adjusted too deep and the material bounces up, or it is adjusted too shallow and it is difficult to tighten the nut.

The original 39mm diameter return rod with spring was replaced with an 80mm diameter double-acting hydraulic cylinder piston rod. The original rod was prone to breakage when performing heavy lifting or prolonged tasks, posing a safety hazard if someone was standing near the machine and could be injured. The improved model eliminates this issue of return rod breakage.

The hydraulic structure is bidirectional hydraulic, with high pressure for forward movement and low pressure for reverse movement during operation. Both forward and reverse movements are hydraulically controlled, achieving separation of high and low pressure, protecting the equipment, and reducing oil temperature. The hydraulic system is the same as that of the Z28-200, Z28-260, and Z28-280 large thread rolling machines, making it more stable and durable.
