Circle Bending and Butt Welding Machine: High-Efficiency Equipment for Production of Rotating Doll Display Stands

In the field of doll display prop manufacturing, the forming and welding quality of the circular frame of rotating display stands directly affects the stability and aesthetics of the product. The circle bending and butt welding machine, with its precise control via full servo drive, efficient production rhythm, and stable welding performance, has become the core equipment for producing iron circular components of rotating doll display stands, bringing the industry an integrated processing solution from wire rod to finished product.

The parameter design of the circle bending and butt welding machine is highly consistent with the production characteristics of rotating doll display stands. The applicable wire diameter range of the equipment is 2-6mm, which exactly covers the common specifications of iron display stand circular frames—whether it is a 30cm diameter display stand for small dolls or a 50cm diameter frame for large dolls, they can all be processed and formed using 2-6mm iron wire. The setting of the circle bending diameter range of 25mm-550mm is more targeted. Among them, the feature that wires with a diameter of 3mm or more can be processed into large circles of 400mm or more perfectly meets the production needs of medium and large rotating display stands. Moreover, the circle diameter ranges corresponding to different wire diameters (such as 2-2.5mm wire diameter adapted to 25-300mm circle diameter) provide flexible choices for multi-specification products.

In terms of production efficiency, the equipment can reach a production speed of 10-20 pieces per minute when taking 80mm diameter as an example. For the commonly used 100-300mm diameter range of rotating doll display stands, the actual production speed is stable at 10-15 pieces per minute, which can not only meet the needs of mass production but also ensure the symmetry and balance of the display stand's circular frame through high-precision control (perimeter tolerance of ±0.2mm, diameter tolerance of ±0.5mm, and flatness less than 0.5mm), avoiding shaking or tilting during rotation.

The equipment adopts a 2-6mm full servo drive design, and its core power configuration highlights precision and stability: the wire feeding motor has a power of 2.6KW (3000 rpm) and a wire feeding speed of 35 meters per minute, which can quickly transport the iron wire to the forming area. Cooperating with the precise control of the 1.0KW servo cutting motor, it realizes the consistency of the cut length of the wire; the linkage control of the circle bending and welding processes avoids the circle diameter deviation caused by mechanical transmission errors in traditional equipment, making the arc of the circular frame uniform and the interface flat.

The welding process is a key guarantee for the durability of the display stand. The equipment is equipped with a 50KVA welding power and adopts resistance butt welding technology. The welded part is smooth and free of burrs, which not only improves the aesthetics of the product but also avoids the problem of fabric snagging caused by rough interfaces during doll display. The 50% duty cycle and 0.6MPa compressed air pressure ensure the stability of the welding process, while the 50L/min cooling water flow effectively controls the temperature of the welding area, preventing the iron wire from deforming due to high temperature and ensuring the structural strength of the frame.

The structural design of the circle bending and butt welding machine provides basic support for efficient production. The overall dimensions of 240014501500mm are suitable for the layout of most production workshops. The 800KG equipment weight not only ensures stability during operation but also facilitates position adjustment in the workshop. The 380V input voltage is compatible with industrial power supply systems, allowing quick commissioning without additional circuit modifications.

In terms of operation, the equipment has highly adjustable parameters. For the diversified designs of rotating doll display stands (such as circular frames with hooks, double-layer nested structures, etc.), quick production change can be realized through preset programs. The response speed of the full servo system makes operations such as circle diameter adjustment and welding strength setting more convenient. Even complex special-shaped circular frames can be formed in one go through precise parameter control, reducing post-processing procedures.

For enterprises producing rotating doll display stands, the value of this equipment is reflected in multiple dimensions: after high-precision circle bending and welding of iron wires, the consistency of the circular frame is improved, reducing the difficulty of adaptation during assembly; the smooth welding interface reduces manual grinding costs and shortens the production cycle; the production speed of 10-15 pieces per minute and stable qualification rate (due to strict tolerance control) effectively reduce the production cost per unit product.

In addition, the versatility of the equipment enables it to be expanded to other fields of circular iron product production, but its targeted performance in the rotating doll display stand industry is particularly prominent—whether it is a large display stand for shopping mall displays or a small display stand for home placement, efficient production can be achieved through flexible parameter adjustment of the equipment. Against the background of the increasing demand for refinement and personalization of display props in the consumer market, the circle bending and butt welding machine, with its characteristics of high precision, high efficiency, and high stability, has become the core equipment for enterprises producing rotating doll display stands to enhance their competitiveness.

Through precise parameter design, advanced servo control, and reliable welding technology, the circle bending and butt welding machine provides an integrated solution for the production of circular frames of rotating doll display stands. It not only meets the processing characteristics of iron materials but also helps enterprises achieve large-scale and standardized production through efficient power configuration and precise transmission systems, injecting technical impetus into the development of the industry.
