The Φ102-Φ219x12mm automatic ERW pipe mill without roller changing designed and manufactured by our company for Hengshui Jinghua Welded Pipe Company was successfully tested in April 2016. The ERW pipe mill without roller changing is the latest patented product developed by our company. When changing the product specifications, all the forming machine parts do not need to replace the rollers. In the past, the precision forming frame that needs to replace the rollers does not need to be replaced on our unit. Can save a lot of roll investment, especially suitable for large and medium-sized units. When changing the product specifications, the adjustment of the rolls is also fully automated. Simply input the parameters such as pipe diameter, wall thickness, and material on the industrial computer, and all the rolls will be automatically adjusted to the appropriate position, and the feed is directly turned on for production. This saves a lot of adjustment time when changing the model, making it possible to produce multiple varieties of small batch orders, increasing the operating rate of the unit and increasing the start-up rate of the unit. And the fully automatic computer type change can also make the adjustment accurate, reduce the error of manual adjustment, improve the yield of the unit, and increase the economic benefit of the unit.
