Embodiment
[0038] A method for manufacturing a cylinder member provided by an embodiment of the present invention, such as figure 1 As shown, the manufacturing method includes:
[0039] Step 101: Coaxially and fixedly connect the first flange and the second flange together.
[0040] Step 102: Processing screw holes on the first flange and the second flange.
[0041] Step 103: Simultaneously weld the first cylinder body and the second cylinder body to the first flange and the second flange respectively.
[0042] In the embodiment of the present invention, first the first flange and the second flange are coaxially fixed together, then the screw holes are processed on the first flange and the second flange, and finally the first cylinder and the second cylinder are simultaneously Welded on the first flange and the second flange respectively, that is to say, the present invention arranges the process of machining the screw holes before the forming of the cylinder member, so that when machi...

Abstract
The invention discloses a manufacturing method of cylindrical members and belongs to the technical field of machine manufacturing. The manufacturing method includes the steps that a first flange and a second flange are coaxially and fixedly connected together; threaded holes are formed in the first flange and the second flange; and a first cylinder and a second cylinder are welded to the first flange and the second flange respectively. The first flange and the second flange are coaxially and fixedly connected together, then the threaded holes are formed in the first flange and the second flange and finally the first cylinder and the second cylinder are welded to the first flange and the second flange respectively, that is, the threaded hole machining procedure is conducted before molding of a cylindrical member, and the first flange and the second flange which are fixed together can be machined at the same time only through a small-sized numerically-controlled machine tool during machining of the threaded holes, so that the manufacturing cost is reduced, and the machining efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to a method for manufacturing a cylinder member. Background technique [0002] When manufacturing a large cylinder, because the volume of the cylinder is too large, it is necessary to manufacture two cylinder components separately, and then combine the two cylinder components into a complete cylinder. Usually, butt flanges are provided on the two cylindrical members, and screw holes are provided on the butt flanges, and the two cylindrical members are connected by bolts through the screw holes on the butt flanges. However, since screw holes need to be provided on the butt flanges of the two cylinders respectively, the requirements for the butt joint accuracy of the two butt flanges are very high. In order to ensure the butt joint accuracy, it is necessary to use a large CNC machine tool to process the cylinder components. Increased manufacturing costs. ...
