Features of the KL Series Long Stroke Cold Forging Press:

The KL series machines are primarily developed for cold forging of long shafts. High rigidity, precision, and efficient multi-station capabilities are the main focus of these devices. The key features are outlined as follows:

1. Deformation knuckle-joint mechanism providing long stroke and excellent slide motion curve: The KL series' deformation knuckle-joint mechanism breaks through the limitations of traditional elbow mechanisms, allowing for longer strokes and expanding the range of workable parts.
2. Additionally, it can be customized to accommodate different types of products, with different slide motion curves designed to meet customer requirements.
3. High Rigidity Slide: The slide design structure of the KL series boasts a rigidity of over 1/9000, making it suitable for precision cold forging. With a two points loading design, it can withstand larger eccentric loads, enhancing its production advantages when paired with multi-station automated transfer equipment.
4. Linkage-type Lower Die Cushion Mechanism: The lower die cushion mechanism uses a linkage mechanism instead of the commonly used cam plate, reducing wear and making the cushion mechanism more reliable and durable. The cushion operates directly connected to the active shaft, ensuring stability and suitability for higher-speed production.
5. Eight-sided Precision High Rigidity Guide ways: Special eight-sided gibs control the clearance between the gibs through wedge adjustment mechanisms. When forging loads occur, the strain caused by the squeezing of the bolster and slide can be released unilaterally to maintain parallelism between the slide and the bolster.
6. High Capacity Die Height and Long Stroke: While conventional forging presses have a die height of about 8-9mm, this series of presses achieves 25mm. Similarly, while conventional forging presses have a stroke length of about 300-400mm, this series reaches 600mm and can be expanded to 800mm to meet special customer requirements. With this special design feature, it becomes possible to forge long shaft components that were previously difficult to produce, thus enhancing the cold forging process.

 

KL Series Long Stroke Cold Forging Press: Benefits and Applications:

Precision die forging has the advantages of energy saving, material saving, carbon reduction, and high efficiency, making it a trend in the forging industry worldwide. Through the application of hot or warm combined with cold precision forging technology, it is possible to obtain forgings with larger weight, complex shapes, and high dimensional accuracy.

　　The KL series represents a breakthrough in cold precision forging technology, with the following benefits：

1. High Precision: Due to the high rigidity and strength of the equipment, it effectively suppresses and absorbs the impact force during stamping. The adjustment mechanism of the slide guide can release extrusion strain, maintaining machine accuracy and ensuring the high precision of the forgings.
2. Long Working Stroke: The long stroke and high capacity forging point overcome the previous limitation of being unable to forge long shaft work pieces.
3. High Automation Production Efficiency: With a large space for two-point load-bearing mold, combined with automated feeding equipment in multi-station process planning, the production rate can reach 20 to 30 cycles per minute, improving production efficiency by streamlining operations and reducing the need for multiple devices.
4. Reduced Equipment Costs: Currently, similar equipment is only successfully developed in Europe and Japan. The Chin Fong KL series meets the same product functional requirements but at a third less cost compared to products of the same grade, reducing manufacturing costs and enhancing industry competitiveness.</ li>
5. Strong and Delayed Material Knock-out: The maximum force of the bed knock-out device is 100 tons, and that of the slide knock-out device is 30 tons. Through the knock-out motion curve, it can be observed that the knock-out action occurs at an angle of 240 degrees in the stroke.

In Conclusion

In summary, with the rapid development of the automotive market, the demand for forgings has been increasing annually. The development of forgings is moving towards light weighting, precision, complexity, and high-efficiency automation. Chin Fong's KL series long-stroke cold forging press is a precision forging multi-station automated production equipment. The forged products meet the characteristics of precision forging, energy saving, and material saving, shortening the production cycle and reducing manufacturing costs. The rational distribution of metal flow along the part's shape improves the organization and performance of the product, achieving light weighting, improved quality, and safety. This forging equipment is currently only produced in Germany and Japan. Taiwan's Chin Fong is the third-largest producer globally and the only factory in Southeast Asia and mainland China that can handle design and manufacturing from start to finish. The cost of its products is one-third lower than similar types produced in Germany, significantly reducing equipment procurement costs and enhancing competitiveness in operations.
