Z28-16 Three-Axis Thread Rolling Machine
Product Introduction
This machine tool primarily consists of a machine frame, three identical thread-rolling spindle assemblies, three identical slide‑sleeve hydraulic cylinder systems, a transmission mechanism, a speed‑change mechanism, an electrical system, and a cooling system, among other components.
The machine body is supported by three identical hydraulic cylinders, whose bases in turn support three identical screw‑rolling spindle assemblies that perform synchronized linear feed and retract motion. This mechanism completes the workpiece clamping, thread‑cutting, and release‑retraction operations. The gearbox delivers driving power, causing the three screw‑rolling spindles to rotate at the same speed and in the same direction, thereby executing the thread‑rolling process.
With the vigorous development of technology and the economy, the construction industry’s demand for compaction machinery is steadily increasing. After all, these are highly efficient machines that save workers time and effort, which is why such equipment has seen widespread adoption in recent years. So, what are the advantages of a three‑axis thread‑rolling machine?
What are the advantages of a three-axis thread-rolling machine?
1. High precision and high efficiency. Modern three-axis thread-rolling machines have become even more “professional” in thread machining, producing threads with perfectly consistent profiles.
2. A three‑axis thread‑rolling machine can save a great deal of money, and hiring a worker is becoming increasingly difficult these days. Ultimately, it’s still best to invest in an automated machine that will last for years, which significantly reduces costs in this area.
3. In recent years, great importance has been attached to environmental protection and hygiene. While some machines may cause environmental pollution to varying degrees, the three‑axis thread‑rolling machine stands out for its zero‑pollution operation and absence of open flames. It can be used anytime, anywhere, helping to shorten project timelines without delay.
4. Excellent quality and high stability. For a three‑axis thread‑rolling machine to be both comfortable and reliable, its stability is paramount. In the construction industry, daily tasks are numerous and complex; if the equipment frequently breaks down, it can be a real headache. The new‑generation rolling mill excels in stability, effectively addressing this major challenge.
5. The three-axis thread‑rolling machine delivers low surface roughness, imparts a certain degree of work‑hardening to the workpiece after rolling, minimizes material waste, and boasts a high level of automation. Its production efficiency is significantly superior to that of cutting, and it offers a long service life. However, it places specific requirements on the workpiece: its hardness must not exceed HRC 40, and die manufacturing is challenging because achieving the required hardness is difficult.
What are the structural components of a three-axis thread-rolling machine?
1. The main body of the three-axis thread-rolling machine is a box‑shaped casting. Its upper surface houses the A and B mounting brackets, the slide block, and the electrical control panel, while the lower side accommodates an oil reservoir for coolant. On the left side of the coolant reservoir is mounted the electrical distribution panel; additionally, there is a hydraulic power unit.
2. The side housing is a frame‑type casting, integrally joined to the main housing via threaded connections. It is equipped with an electrical distribution box, a support bracket for the main motor, and other components, all of which have been installed.
3. Distribution Box: The three-axis thread-rolling machine is primarily equipped with a gear and a shaft. The box serves to transmit power from the main motor to the housing, with the drive being evenly conveyed via a reducer to the two roller shafts. A hollow gear shaft is positioned in the center of the housing, allowing long workpieces to pass through easily.
4. Transmission Gearbox: The three‑axis thread‑rolling machine boasts substantial processing capacity. Its transmission system employs a Type 400 reducer, with an extended drive shaft that increases torque; the gear module and output force are larger than those of standard gearboxes.
5. Rolling system: Composed of a fixed base, a sliding base, and a wheel‑rod mechanism.
6. Cooling System: In the three-axis thread‑rolling machine, the electric pump delivers coolant through piping to the nozzle, which allows adjustment of the flow rate. Do not overfill with coolant—ensure the level does not exceed 4 cm above the oil‑suction inlet. Excessive coolant can easily enter the motor and damage the pump. Coolant may be 20‑grade machine oil, or a suitable amount of diesel fuel may be added.
