The thread rolling machine is used to produce precise, small screws such as needle screws, electronic screws, straight/diagonal patterns, and other precision parts using an eccentric rolling process.
The thread rolling machine offers several advantages, including:
- High efficiency and precision
- Durable construction
- Extremely straightforward operation
- Versatile range of applications.
The thread rolling machine uses two rollers to form screws through a rolling process, rather than the traditional cutting method. This process involves an effective cooling and casting procedure, which results in not only a faster and more precise production of screws, but also greater strength, shear resistance, and durability compared to screws produced through cutting.
Thread rolling machine classification
The thread rolling machine is a versatile cold rolling forming machine. It can perform various rolling operations on the workpiece in a cold state, such as thread rolling, straight rolling, twill rolling, gear rolling, spline rolling, straightening, reducing diameter, and various forming rolling.
The machine features a safe and reliable electro-hydraulic control system, which allows for operation in manual, semi-automatic, and automatic modes.
The cold rolling process used by the machine is an advanced, non-cutting process that enhances the intrinsic and surface quality of the workpiece. The radial compressive stress generated during processing also significantly improves the fatigue and torsional strength of the workpiece, making it an efficient, energy-saving process.
Thread rolling machines come in several types, including two-axis eccentric, two-axis rolling, two-axis hydraulic, two-axis hydraulic rolling, triaxial cam, three-axis hydraulic, and triaxial hydraulic rolling.
When machining threads, the roller molds are mounted on the rotating shafts of the two-axis or three-axis machine, and the threads are formed through extrusion. Different threads can be produced by replacing the roller die of different sizes. The machine is capable of processing triangular threads, ladder patterns, straight lines, net patterns, twill, and more.
Thread rolling machine advantages
The product produced by the thread rolling machine is stable in size and highly precise. For the mass production of precision screws, there are two types of thread rolling machines available: the fixed type and the rolling type.
The fixed type can be equipped with a vibrating plate for full automation if the size allows. The rolling type is better suited for machining workpieces with larger lengths.
The three-axis machine is specifically designed for processing hollow pipe threads and tube parts. With its equilateral triangle support, the roundness, high precision, concentricity, and verticality of the workpiece are ensured.
The thread rolling machine is an essential tool in the fastener industry.
