Working Principle of Dual Servo Spinning Welding Machine

The dual servo spinning welding machine operates based on the principles of friction heating and plastic melting, achieving high-precision motion control through a dual servo motor system. During operation, one servo motor drives the upper mold (or workpiece) to rotate at high speed, while another servo motor precisely controls the axial pressure and feed speed, ensuring that the surfaces of two circular plastic workpieces to be welded come into close contact and generate relative friction. In the process of friction, mechanical energy is converted into thermal energy, rapidly heating the plastic surface to a molten state. Subsequently, the servo system precisely controls the rotation stop and hold time, allowing the molten plastic to fully fuse under pressure. After cooling and solidification, a high-strength weld joint is formed. This process is monitored and adjusted in real-time by the PLC control system to ensure the stability and consistency of welding quality.

Comprehensive Introduction

The dual servo spinning welding machine is a welding equipment that integrates high precision, flexibility, and intelligence. Compared to traditional pneumatic or single servo welding machines, its dual servo drive system achieves independent and precise control of rotational speed and axial pressure, effectively avoiding issues such as false welding and overflow, with a welding yield rate of over 99%. The equipment supports welding circular workpieces with diameters ranging from 10mm to 500mm. Through modular design and parameterized programming, it can quickly switch between different product processes to adapt to diverse production needs. In addition, the equipment is equipped with an intelligent touch screen and a data monitoring system, supporting the storage of process parameters, traceability of production data, and fault prediction functions. Combined with automated loading and unloading integration, it significantly improves production efficiency and management level, making it a core equipment for modern manufacturing to achieve efficient and stable welding.
