A two-axis bar Thread Rolling Machine is a mechanical device that uses two synchronously rotating thread rolling wheels to cold-extrude and form workpieces. It is mainly used for processing external threads, straight threads, and oblique threads.
Its core features include
Structural Composition
Primarily composed of a machine body, rotating box, fixed spindle seat, movable spindle seat, hydraulic system, and electrical components.
01
Working Principle
The two spindles rotate synchronously in the same direction. The movable spindle seat is horizontally fed under hydraulic pressure, and the thread rolling wheels roll the workpiece to form threads.
02
Processing Range
Suitable for rolling workpieces with diameters of 12-100mm. Materials must meet the following requirements: elongation >10%, compressive strength <100kgf/mm² (carbon steel, alloy steel, and non-ferrous metals).
03
Advantages
Simple operation, automatic positive thread switching, high thread accuracy; stable performance, small footprint, energy saving; suitable for processing solid workpieces, strong load-bearing capacity, high efficiency.
04
Application Scenarios
Widely used in industries such as construction and fasteners, such as rebar thread processing.

Yushi thread rolling machine advantages compared with other supplier
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.

FAQ
Q: What is the basic principle of a bar Thread Rolling Machine?
A: As the name suggests, a thread rolling machine's main function is to process metal wires through rolling. Through a special roller design, the thread rolling machine can process wires into various shapes with high efficiency and precision. In this process, the material's strength is increased, and the surface finish is also significantly improved.
Q: Where are thread rolling machines needed?
A: In the automotive industry, thread rolling machines are used to produce high-strength bolts and nuts. In the aerospace field, they ensure that every component can withstand extreme working environments. Even in everyday life, industries such as home appliance manufacturing and electronics production rely heavily on thread rolling machines. Therefore, the wide range of applications for thread rolling machines is truly astonishing!
Q: How do thread rolling machines help companies improve production efficiency?
A: First, thread rolling machines are highly automated, enabling mass production and significantly shortening the production cycle. Second, their high processing precision reduces material waste and lowers production costs. Furthermore, they are simple and easy to operate, allowing for quick learning and reducing the time required for manual training.
Q: What are some things to consider when purchasing a thread rolling machine?
A:When choosing a suitable thread rolling machine, companies should consider several aspects. First, the performance and stability of the equipment are paramount; after all, only stable equipment can guarantee continuous production. Second, after-sales service is also crucial, as good after-sales support can save companies a lot of trouble. Finally, price is another factor that must be weighed; finding equipment with a high cost-performance ratio is the wise choice.
Q: What are the working principles of a thread rolling machine?
A: It consists of three stages:
Pre-treatment: Before thread rolling begins, the workpiece needs to undergo necessary pre-treatment, such as degreasing and cleaning.
Rolling: This stage is the core of the thread rolling machine. Under the action of the rollers, the workpiece is rolled under high pressure to gradually form threads.
Post-treatment: After rolling, the workpiece needs to undergo inspection and further processing to ensure the quality and accuracy of the threads.
