Product Description

Product Description

SJNF Series 8-Station Long Stroke Cold Former

The SJNF Series 8 - Station Long - Stroke Cold Formers are high - performance industrial machines designed for precision cold forging operations. These machines are engineered to meet the diverse needs of metal forming in various manufacturing sectors.
1. Model Diversity and Basic Configuration
This series offers a comprehensive range of models, including SJNF 11B - 8SL, 14B - 8SL, 19B - 8SL, 24B - 8SL, 33B - 8SL, and 41B - 8SL. Each model is equipped with 8 forging stations, ensuring efficient and multi - stage forming processes.
2. Precision Forming Parameters
Cut - off Capabilities: The maximum cut - off diameter ranges from 11mm to 40mm, and the maximum cut - off length varies from 36mm to 85mm across different models. This allows for precise control over the raw material input for forging.
Ejection and PKO Lengths: The kick - out length (rear ejection) spans from 40mm to 120mm, and the PKO length (front ejection) ranges from 16mm to 35mm. These parameters ensure that the formed parts can be smoothly ejected from the machine after the forging process, facilitating continuous production.
Die Pitch and Stroke: Die pitch values range from 50mm to 165mm, and the ram stroke varies from 160mm to 360mm. These dimensions are crucial for shaping the metal parts accurately and accommodating different part sizes and shapes.
3. Power and Production Capacity
Forging Power: The forging power of these machines ranges from 60,000 kgs to 550,000 kgs. This substantial power enables the machines to handle a wide variety of metal materials and perform high - strength forging operations.
Production Speed: The output for nuts ranges from 40 - 75 pcs/min to 55 - 140 pcs/min depending on the model. This allows manufacturers to choose the appropriate model based on their production volume requirements, whether for small - batch, high - precision production or large - scale mass production.
4. Motor and Lubrication Systems
Main Motors: The main motor power ranges from 15kw to 220kw, providing sufficient power for the forging processes.
Lubrication System: The lubrication motor power is 1.5kw or 2.2kw, and the lubricant capacity ranges from 800L to 3000L. A proper lubrication system ensures the smooth operation of the machine, reduces wear and tear, and extends the service life of the equipment.
