The LCW-0QJ air spring forming machine is a highly integrated and efficient system designed for precision tire manufacturing. It consists of a main molding unit, a lower pressing roller assembly, a radial shrinking tire forming head, a tailstock device, a full base, a pneumatic piping system, and an advanced electrical control system. The entire structure is built on a single, unified base for ease of installation, transportation, and maintenance. The motor drives the spindle, which is connected to the forming head via a sleeve coupling. This forming head is specifically designed for radial contraction, enabling the folding process through a pair of synchronized cylinder mechanisms.
The machine employs PLC-based automatic control combined with a touch screen interface, allowing both manual and automated operations. It can move axially and rotate around the forming drum, using the pressure from the air cylinder and a precise transmission system. During operation, the forming head maintains the optimal state of a simply supported beam, ensuring stability and accuracy.
To enhance flexibility and reliability, the rear roller seat moves along a linear guide, making the system more adaptable and durable. During the rolling process, the cylinder is pressurized, and the two pressure rollers are positioned on the forming drum. The motor drives the left and right screws via a chain, moving the pressure rollers apart. When the desired position is reached, a contact block triggers a limit switch, releasing the cylinder pressure and lowering the rollers. The motor then reverses, bringing the rollers back to their initial position, preventing central pressure leakage and ensuring high-quality molding.
The pressing speed of the roller is independent of the forming drum's diameter, resulting in consistent rolling time and eliminating any leakage issues. This significantly improves the quality of the green tire. Additionally, the rolling speed and return speed of the empty car can be adjusted using variable frequency control, making the machine suitable for various specifications and production needs.
To meet product requirements, the entire base is designed to ensure high manufacturing precision, ease of transport, installation, commissioning, and maintenance. It also supports future equipment adjustments and migrations. The main machine housing, lower pressing roller, and tailstock assembly are all mounted on the base. Electrical and pneumatic components are neatly routed within the frame, enhancing safety and visual appeal.
The air spring forming head shares a similar design with the first radial tire forming head. For air spring applications, the outer tile curve is divided into multiple segments that conform to the forming curve when opened and fit within the steel ring’s diameter when stacked, allowing for easy blank removal. The forming head and mandrel are assembled as a single unit, making it quick and simple to change specifications. The tire building head features both cylindrical and tapered forming heads, with the ability to handle different steel ring diameters on either side. When a tapered structure is required, the forming head is designed accordingly.
