Z28-63 Large Thread Rolling Machine
Product Introduction
It is primarily used for roll-forming various precision external threads, including ordinary threads, trapezoidal threads, and module threads. It can also perform forming, straightening, burnishing, and thread-rolling operations on cylindrical workpieces. Suitable materials for roll-forming include carbon steels, alloy steels, and nonferrous metals with an elongation of greater than 10% and a tensile strength of less than 1000 N/mm².
This machine can be equipped with an automatic feeding device according to user requirements.
Literally speaking, a large-scale thread‑rolling machine is a versatile cold‑extrusion machine tool. Imported thread‑rolling machines can, within their specified rolling pressure range, perform cold‑state rolling on workpieces with threaded, straight, or helical surfaces. This advanced non‑cutting process effectively enhances both the internal and surface quality of the workpiece. The radial compressive stresses generated during machining significantly improve the workpiece’s fatigue strength and torsional resistance, making it an ideal, energy‑efficient, low‑consumption manufacturing method.
The key features of large thread‑rolling machines include the following: First, they are specifically designed for thin‑walled tubes with wall thicknesses of 1.5 mm or greater, capable of forming threads, mesh patterns, straight sections, and triangular supports, while ensuring roundness, concentricity, and perpendicularity. Powered by hydraulic pressure, they offer simple operation, smooth speed control, and stable performance. Second, the machine boasts a compact design: its cast‑steel frame provides high rigidity, the structure is straightforward, it incorporates an integrated oil tank to minimize space requirements, and maintenance is convenient. It can also be equipped with an automatic feeding system to enable automated production. Third, it features variable‑frequency drive, allowing the spindle speed to be adjusted freely, with PLC control and an intuitive human–machine interface. Fourth, it offers comprehensive functionality, seamlessly switching among automatic, semi‑automatic, and manual modes; when full automation is not required, the feeding device can be removed, and the machine can be switched to semi‑automatic mode for manual operation.
Large thread‑rolling machines not only facilitate the machining of various pipe threads but are also suitable for knurling, mesh patterns, and straight‑line threading. They employ an equilateral‑triangle support system to ensure roundness and perpendicularity, and allow for easy passage of gauge rods during setup and adjustment. Powered by hydraulic pressure, these machines are simple to operate, stable, and durable, making them widely used in thread‑rolling operations on oil‑pipe fittings, automotive and bicycle components, air‑conditioner evaporator tubing, a variety of fasteners, condenser copper tubes, and other workpieces.
When it comes to maintaining a large thread‑rolling machine, first lubricate the components before starting work; an appropriate amount of oil will help prevent wear on the rolling dies. Next, inspect the machine for loose screws or other issues to ensure smooth operation and avoid malfunctions during use. If no problems are found, run the machine on a trial basis for a short period to check for wiring faults. Once these checks are complete, you can proceed with thread‑rolling.
During the wire‑making process, it’s important to maintain consistent feed timing. If budget allows, consider purchasing an automatic feeder to save time and effort—most importantly, reduce costs without compromising productivity, thereby significantly boosting operational efficiency. For large thread‑rolling machines, regular maintenance is essential, and foundational upkeep must be performed diligently.
In addition, by properly addressing these two factors during production, the wear on large thread‑rolling machines can be significantly reduced, thereby extending their service life.
Key point 1: Regularly inspect the large thread‑rolling machine for metal chips. Such machines readily generate metal debris during the rolling process; if left uncleaned for an extended period, this debris can accumulate into sludge, leading to wear on the thread‑rolling wheel’s surface. Therefore, it is essential to periodically check for foreign matter and clean it promptly. By doing so, the service life of the thread‑rolling machine can be extended to a certain degree.
Key point two: Lubricant must be used; this is an effective way to reduce wear on large thread‑rolling machines. During the threading process, the lubricant both lubricates and protects the rollers, significantly lowering the friction between the rollers and the workpiece.
