A Steel Thread Rolling Machine is a machine used for processing reinforcing bars. It produces high-precision threads on the ends of reinforcing bars through a single rolling process, thereby improving strength. It mainly consists of a frame, clamping mechanism, feed slide, reducer and thread rolling head, cooling system, and electrical system. It features high processing speed, simple operation, good stability, and reliable quality.
Product Components
Frame: Supports and secures the entire machine structure.
Clamping Mechanism: Used to clamp the reinforcing bars, ensuring stability during processing.
Feed Slide: Controls the feed movement of the thread rolling head onto the reinforcing bars.
Reducer and Thread Rolling Head: The reducer provides power, and the thread rolling head is responsible for cutting and rolling the threads.
Cooling System: Cools the thread rolling head and workpiece during processing, reducing temperature and extending equipment life.
Electrical System: Controls the machine's start, stop, feed, and retraction functions.

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 are the consequences of incorrect installation of the forward and reverse threads on a Steel Thread Rolling Machine?
A: Incorrect installation of the forward and reverse threads on a thread rolling machine may result in threads that do not meet requirements, affecting the connection quality of the reinforcing bars. Furthermore, it may damage components of the thread rolling machine, shortening its service life.
Q: How to reduce wear and tear on thread rolling machines?
A: First, regularly check your thread rolling machine for metal shavings. These types of metal machinery easily generate metal shavings during thread rolling. If not cleaned regularly, these shavings will accumulate and cause wear on the surface of the thread rolling wheels. Therefore, it is essential to regularly check for shavings and clean them promptly. Doing this will extend the service life of the thread rolling machine.
Second, always use lubricating oil. This is the most effective way to reduce wear. During thread processing, this lubricating oil lubricates and protects the thread rolling wheels, greatly reducing the resistance generated during the rolling process between the wheels and the workpiece.
These two points are clear! Following these two points will significantly reduce the wear on your thread rolling machine, thereby extending its service life.
Q: What causes a thread rolling machine to fail to produce threads?
A: I believe those familiar with the industry know how threads are produced! But what if a thread rolling machine suddenly stops producing threads? Let me explain!
First, we need to rule out whether we've reversed the two directions of the thread rolling machine's pressure head. If so, the machine cannot roll the rebar properly, and naturally, it won't produce threads.
Second, check the machine's positioning device. If this device isn't installed correctly, the machine will automatically assume a malfunction and malfunction.
Finally, prolonged use of the thread rolling machine without proper maintenance can cause problems. For example, insufficient or no lubrication, or leaving cutting debris on the rolling shaft. Maintaining these conditions for an extended period will naturally lead to machine malfunctions.
Therefore, based on the three aspects mentioned above, after ruling out the first two factors (improper installation), the last point is crucial and must be addressed promptly. Proper maintenance can even extend the machine's lifespan!
