Ring Making and Butt Welding All-in-One Machine 2-6: High-Efficiency Forming Expert for Kitchen Stainless Steel Colanders

Ⅰ. Equipment Overview

Equipment Name: Ring Making and Butt Welding All-in-One Machine 2-6

Application Industry: Specialized in producing iron components for kitchen utensils such as stainless steel colanders, filter screens, and kitchen hangers, realizing a fully automated ring making and welding process from 2-6mm iron wire feeding to finished ring frames. Aiming at the strict hygiene standards and structural strength requirements of the kitchenware industry, the equipment solves pain points such as large dimensional deviations and unstable welds in traditional manual ring bending and welding with ±0.5mm-level precision and a production speed of 10-15 pieces/min, becoming the core equipment for large-scale production of stainless steel colanders.
Technical Highlights: The full servo drive system, combined with a 50KVA welding power, supports the forming of ring frames with a diameter of 25-550mm, suitable for producing multi-specification components such as colander heads and handle rings, and compatible with materials like Q235 carbon steel and 304 stainless steel.

Ⅱ. Analysis of Core Performance Parameters

(1) Production Efficiency and Flexible Adaptation

• Standard Capacity: 10-15 pieces/min (universal diameter range). Taking an 80mm diameter colander ring as an example, the capacity can reach 10-20 pieces/min, increasing efficiency by 6-8 times compared to traditional manual operations.
• Dynamic Diameter Adjustment: The ring making diameter is adjustable from 25mm to 550mm, suitable for full-specification production from small colander filter hole rings to large soup colanders (e.g., 2mm wire diameter supports 25-300mm ring diameter, and 6mm wire diameter supports a maximum of 550mm).
• Intelligent Efficiency Matching: The production speed decreases linearly with the increase of diameter. The system automatically optimizes wire feeding tension and welding parameters to ensure stable output of colander frames with a diameter of 300-600mm.

(2) Precision Control and Material Compatibility

• Wire Adaptability: Specialized in 2-6mm low-carbon steel and 304 stainless steel wires, supporting cross-sectional shapes such as round and flat wires, meeting the food-grade contact standards of the kitchenware industry.
• Precision Indicators:
  • Ring making diameter tolerance ±0.5mm ensures the consistency of colander frame roundness;
  • Circumference tolerance ±0.2mm provides precise interfaces for seamless welding of filter screens and frames;
  • Flatness <0.5mm ensures the flatness of the colander bottom filter screen after tensioning.

(4) Mechanical and Auxiliary Systems

• Ring Making Mechanism: Made of Cr12 die steel (hardness 58-62HRC), through adjustable positioning columns and a 360° rotating die head, it realizes quick model change for different diameter ring frames, with a die life of over 150,000 times, adapting to the needs of special-shaped frames such as colander arcs and ovals.
• Welding Module: Pneumatic butt welding fixtures combined with copper alloy electrodes, and a 50L/min circulating water cooling system support a 50% duty cycle (5 minutes of full-load work every 10 minutes) to avoid equipment overheating caused by long-term welding.
• Pneumatic System: Driven by 0.6MPa compressed air, it controls actions such as feeding, positioning, and welding, with a response time <50ms, ensuring the synchronization accuracy of each process is ±0.2mm.

Ⅲ. Core Advantages of the Equipment

1. Full Servo Intelligent Control: Equipped with a Xinjie PLC control system, supporting the storage of 200 groups of production data. After inputting the ring diameter parameters, it automatically completes the entire process of "wire feeding - straightening - ring making - cutting - butt welding", with a model change time <2 minutes, reducing manual debugging errors.
2. Hygiene-Grade Quality Assurance: Smooth welds without burrs, no need for secondary grinding, in line with GB 4806.9 food-contact metal material standards; flatness and roundness control ensure no deformation after the filter screen is tensioned, avoiding food residue.
3. Energy Saving and Durability: The total power is about 3.3KW, saving 40% more energy than traditional equipment; the water cooling system combined with a cooling fan keeps the temperature of core components ≤65℃, and the equipment continuous operation life exceeds 100,000 hours.
4. User-Friendly Operation: Touch screen + button dual-operation mode, supporting Chinese interface. Novices can take up their posts after 1 hour of training, reducing the labor cost of kitchenware production enterprises.

Ⅳ. Application Scenarios: Full-Process Coverage of Stainless Steel Colanders

• Spoon Head Frame Forming: 300-600mm diameter ring frame making and welding, as the main support structure of the colander. After welding with the filter screen, the load-bearing capacity reaches more than 5kg, meeting the needs of different specifications of colanders such as soup pots and woks.
• Handle Ring Welding: 25-100mm diameter small ring forming, used for the connecting ring between the colander handle and the spoon head. The ±0.5mm precision control ensures that the swing amplitude after handle installation is <1°, improving the user experience.
• Filter Frame Processing: For the reinforcing ring at the edge of the colander filter hole, after 2-3mm wire diameter ring making and welding, combined with the flanging process, it prevents the filter screen edge from cutting hands, in line with kitchenware safety standards.
