Hollow screw is building a lead screw, also known as the oil, jacking, screw, etc, can rise to adjust the height and support the role of, its production process and solid screw is slightly different, hollow screw production is different from solid screw it by ordinary screw rolling machine thread rolling after cutting, welding and become, by the steel tube made of three axis screw rolling machine.
Hollow lead screw relatively higher requirements, the product is more precise, the use of ordinary lead screw machine is likely to crush the hollow lead screw tube.In terms of processing, compared with solid screw, hollow screw is difficult to flow out of the plating material after galvanized or lacquered. If the surface processing is needed, holes should be left on the supporting sheet to facilitate the flow out of the plating material.Under normal circumstances, the requirements of hollow lead screw are no less than 37mm. Generally speaking, the lead screw of more than 37mm has been used on the construction site for a long time. After the inner wall of steel pipe enters sundries, the lead screw is usually not inserted or pulled out, so 37mm is relatively common.The hollow lead screw has fast heat dissipation and can be cooled by the central oil, which can reduce the deformation of the lead screw caused by heat generated by friction when used for a long time, thus ensuring the high precision of the lead screw for a long time.Hebei yanxinsenyu hollow screw, using high quality raw materials, advanced processing technology, in strict accordance with national standards for production, not only to ensure the safety and stability of the product.At the same time, it also increases the service life of products and reduces maintenance costs, thus making products durable.
