The Base Jack & U Jack is a kind of construction screw, also known as oil tray, top support, screw rod, etc. It can play the role of adjusting height and support. Its production process is slightly different from solid screw, hollow screw The production is different from the solid screw, which is cut and welded by a common thread rolling machine, and is produced by a three-axis thread rolling machine for steel pipes. The hollow screw has relatively high requirements and the product is more precise. It is very likely that the hollow screw tube will be flattened by a common screw machine. In terms of processing, since the Base Jack & U Jack is galvanized or immersed, it is difficult to flow out of the enamel plating material with respect to the solid screw. If surface processing is required, a hole is required in the supporting sheet to facilitate the leaching of the enamel plating material.
Under normal circumstances, the requirements of the Base Jack & U Jack are not less than 37mm. Under normal circumstances, the screw of 37mm or more is used for a long time on the construction site. After the inner wall of the steel pipe enters the sundries, the screw is generally not inserted or pulled out, so 37mm More common. The Base Jack & U Jackcan dissipate heat quickly, and can also be cooled by the center oil. When used for a long time, the screw can be deformed due to heat generated by friction, thereby ensuring high precision of the screw for a long time.
The Base Jack & U Jack of Hebei Yanxin Senyu uses high-quality raw materials, advanced technology processing, and strictly in accordance with national standards for production, which not only ensures the safety, reliability, stability and stability of the products. At the same time, it also increases the service life of the product and reduces the maintenance cost, so that the product is durable.
