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: Do you know the manufacturing process of Round Bar Threading Machine?
A:You all know what hydraulics is, right? Thread rolling machines rely heavily on hydraulic systems, which provide the propulsion and are a chipless machining method. This hydraulic system has a box inside the machine containing hydraulic lubricating oil. Once you've adjusted the spacing between the thread rolling wheels, a single button start causes this hydraulic oil to be automatically sprayed out along with the wheels. Its presence protects the thread rolling wheels from excessive wear and maintains the precision of the threads.
With the advancement of technology, most machines now incorporate hydraulic systems. It's considered an essential component.
Q: What are the different methods for machining threads using a thread rolling machine?
A: It primarily produces threads using liquid rolling on a shaft wheel, with patterns including straight threads, helical threads, and other styles. The main system is operated via the machine's central control panel. It offers fully automatic and semi-automatic modes for users to choose from. Regardless of the thread pattern you're rolling, selecting the correct die is crucial to achieving the desired pattern. Coolant is essential during the rolling process to prevent the machine from overheating due to excessive rolling speed; adding coolant ensures safe operation later.
There are various types and models of thread rolling machines on the market, including two-axis and three-axis models. Choosing the right machine depends on the size, specifications, and material of the workpiece, including its diameter. This is essential research before purchasing.
