Thread Rolling Machine For Bolt are multi-functional cold extrusion forming machine tools capable of performing thread rolling, straight knurling, and oblique knurling on workpieces within their rolling pressure range. This is a non-cutting machining process that significantly improves the fatigue strength and torsional strength of the workpiece. Based on the number of axes, they are mainly divided into two-axis and three-axis thread rolling machines: two-axis machines are suitable for processing solid workpieces (such as hardware parts and standard parts), with lower prices but more complex maintenance; three-axis machines are specifically designed for thin-walled tubular parts (such as hollow lead screws), using equilateral triangular supports to ensure roundness and concentricity, but with higher operational risks. Modern thread rolling machines are generally equipped with electro-hydraulic control systems, supporting manual, semi-automatic, and automatic working modes, and are highly efficient and energy-saving.
Core Functions and Advantages
High-precision machining: Improves the surface quality and internal strength of the workpiece through cold rolling, resulting in a stable and smooth machining process.
High degree of automation: Some models support PLC control and automatic feeding, reducing manual intervention and lowering the error rate.
Wide applications: Applicable to construction, automotive parts, fasteners, and other fields, especially suitable for 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 types of Thread Rolling Machine For Bolt are there?
A: There are many types of thread rolling machines on the market, mainly vertical, horizontal, and CNC types. Each type has its unique advantages and applicable scenarios. For example, vertical thread rolling machines are suitable for small-batch production, while CNC machines are suitable for large-scale automated production.
Q: What is the working principle of a thread rolling machine?
A: The working principle of a thread rolling machine is actually quite simple. It uses a pair of specially designed rollers that apply pressure to the raw material through rotation, thereby forming the desired thread shape. In short, it transforms the raw material into the desired thread shape under the pressure of the rollers. Isn't that amazing?
