QJ Four Link Slotter and Corner Cutter – High-Efficiency Industrial Machinery for Precision Slitting and Corner Cutting This robust QJ four-link slotter and corner cutter is engineered for professional sheet metal processing, delivering reliable performance in manufacturing environments worldwide. Designed with precision mechanics and durable components, this machine excels at producing consistent slits and clean corners on a wide range of materials including steel, aluminum, and coated sheets. Whether you're in automotive fabrication, construction, or metalworking industries, this equipment ensures accuracy, speed, and safety—all critical factors for modern production lines. Key Features: - Multi-model options: Available in QJ2000, QJ2500, and QJ3000 configurations to match varying sheet widths (2000mm–3000mm) and production needs. - Dual knife system: The QJ2500 model includes two interchangeable blades—7mm and 10mm—to accommodate different slot sizes (e.g., 7×480mm or 10×480mm), enhancing versatility across applications. - Efficient power transmission: Powered by a 1.5kW to 2.2kW motor (depending on model), the machine uses belt-pulley and gear-driven crankshaft mechanisms for smooth operation and minimal vibration. - Optimized cutting speed: Ranges from 38 to 40 pieces per minute, offering high throughput without compromising edge quality or material integrity. - Compact yet sturdy design: Dimensions vary between 2250×1170×1500mm and 3500×1500×1700mm, with weights ranging from 1000kg to 1500kg, ensuring stability during continuous use. - Built-in safety features: Includes mechanical interlocks and protective guards to reduce operator risk while maintaining workflow efficiency. Detailed Description: The QJ series four-link slitter and corner cutter operates using a synchronized upper-lower blade mechanism driven by a belt-driven crankshaft system. This mechanical setup allows precise control over both slitting depth and corner shaping, making it ideal for producing custom profiles in industrial sheet goods. The machine’s modular design supports easy maintenance and quick tool changes, minimizing downtime. Its reinforced frame and hardened steel components ensure long-term durability even under heavy-duty conditions. With adjustable parameters for slot width, corner size, and feed rate, operators can fine-tune settings for optimal results based on material thickness and desired output. Ideal Use Cases: Perfect for manufacturers requiring accurate edge preparation before welding, bending, or assembling sheet metal parts. Common applications include HVAC ductwork, structural framing, appliance panels, and architectural metalwork. It's particularly suited for facilities that process medium to large volumes of flat sheets and need consistent, repeatable cuts for downstream processes such as CNC punching or robotic assembly. Customer Feedback: Users praise its reliability in daily operations, especially the ease of adjusting blade spacing and the low noise level compared to older models. Many highlight how the dual-knife feature reduces the need for multiple machines, saving floor space and labor costs. Operators also appreciate the intuitive layout and clear markings on the control panel, which simplify routine adjustments and troubleshooting. Frequently Asked Questions: What materials can this machine handle? It works effectively with cold-rolled steel, galvanized sheets, aluminum alloys, and other thin-to-medium gauge metals up to 3mm thick. Is technical support available internationally? Yes, the manufacturer provides detailed manuals, video tutorials, and remote assistance through authorized distributors in various regions outside China. How often should the knives be replaced? With regular sharpening and proper maintenance, blades last approximately 6–12 months depending on usage intensity and material hardness. Can the machine be customized for specific dimensions? While standard models are optimized for common sheet sizes, some variants may be tailored to meet unique production requirements upon request. This industrial-grade slotting and corner-cutting solution combines proven engineering with user-centric functionality—making it an essential asset for any serious metal fabrication facility seeking precision, productivity, and longevity.
