Hollow lead screw is a kind of construction lead screw, also known as oil support, top support, lead screw, etc., which can play the role of adjusting height and support. Its production process is slightly different from solid lead screw. The production is different from the solid lead screw. It is cut and welded after rolling with an ordinary thread rolling machine, and is produced by a three-axis thread rolling machine for steel pipes. The hollow lead screw has relatively high requirements and the product is more precise. It is likely that the ordinary lead screw machine will flatten the hollow lead screw tube. In terms of processing, since the hollow lead screw is galvanized or dipped, it is difficult for the Qin plating material to flow out compared to the solid lead screw. If surface processing is required, holes must be left in the support plate to facilitate the Qin plating material to flow out.
Under normal circumstances, the requirements of hollow screws are not less than 37mm. Generally, screws with a diameter of more than 37mm have been used on the construction site for a long period of time. After the inner wall of the steel pipe enters into the sundries, the screw is generally not inserted or pulled out, so 37mm More common. The hollow lead screw dissipates heat quickly, and can also be cooled by the center oil. When used for a long time, it can reduce the deformation of the lead screw caused by the heat generated by friction, thereby ensuring the high precision of the lead screw for a long time.
