The WFY4 Series spiral coil production line mainly consists of the main machine, control system, and auxiliary equipment.
The main machine is the core part of the production line, responsible for the production and processing of spiral coils.
The control system is responsible for controlling the operation of the production line, including the adjustment of parameters such as speed and pressure.
Auxiliary equipment includes spiral pipe vertical support racks, spiral pipe horizontal discharge racks, etc., which are responsible for assisting the production of spiral coils.
The production line features precise forming and labor saving.Moreover, the control system can be customized according to customer needs to meet their requirements.
Producing spiral coils by rolling one or more straight pipes into spiral coils with adjustable pitch.
It is applied in fields such as boilers and pressure vessels to improve production efficiency and reduce production costs.
It is suitable for producing spiral coils of various materials, such as stainless steel, carbon steel, alloy steel, etc.
It is suitable for producing spiral coils for various purposes, such as boilers, petrochemicals, electric power, shipbuilding, aerospace, etc.
The hydraulic diameter auxiliary adjustment mechanism supports the material during forming, optimizes the bending diameter accuracy, maintains and corrects diameter data, and ensures the consistency of the diameter of each coil turn.
The material support matches the main machine, with opposed rollers feeding in parallel. Two opposite driving rollers clamp the round pipe into the machine, ensuring sufficient friction and uniform speed during coiling. Even small-diameter forming of large-diameter materials can be easily achieved.
The pitch correction mechanism on the hydraulic coil production line is mainly divided into two parts: one is the hydraulic pitch pushing top roller integrated into the lifting rack mechanism; the other is the pitch auxiliary pushing pressure plate integrated into the electric horizontal material support mechanism. They can ensure that each coil turn is in the correct position during coiling, disperse the backward retraction and elastic deformation of the finished coil, and keep the force of the incoming pipe consistent, so as to ensure that the finished product is processed within precise data.
With over 20 years of deep cultivation in the industry, the company has formed four mature business segments:
