Embodiment 1

[0027] First, according to the inner and outer diameters of the finished cylindrical thin-walled ring, determine the thickness of the blanking plate (the degree of the blanking ring). Due to the stretching in the shaping process, the thickness of the blanking plate is slightly greater than the difference between the inner and outer diameters of the finished ring Then, set the outer diameter of the blanking ring, according to the inner diameter, outer diameter and height of the finished cylindrical thin-walled ring, by the principle that the mass and density of the material are constant, and the volume of the material is constant, the blanking is calculated. The inside diameter size of the ring.

[0028] For example: the inner diameter of the finished cylindrical thin-walled ring is 53.0mm, the outer diameter is 55.1mm, the height is 3.2mm, the thickness of the blanking plate is 1.2mm, slightly greater than 1.05mm (half of the difference between the inner and outer diameters of ...

Abstract

The invention discloses a method for machining cylindrical thin-walled rings. The method includes steps of (1), designing raw materials; (2), cutting rings; (3), flanging the rings by 45-degree angles; (4), stretching and shaping the rings. The method has the advantages that the surfaces of the cylindrical thin-walled rings manufactured by the aid of the method are smooth and flat, and the cylindrical thin-walled rings are high in dimensional accuracy; operation is simple and convenient in a technological process of the method, the production efficiency can be improved, and the raw materials can be saved.

Description

technical field [0001] The invention relates to the field of mechanical processing design, in particular to a processing method of a cylindrical thin-walled ring. Background technique [0002] The processing of cylindrical thin-walled rings is generally cut by tube lathe, and the blank is then processed on the plane and the inner and outer diameters, or the sheet is stretched into a cylindrical shape and then cut. Since the width of the cutting knife is about 3mm, it causes Waste of material and extension of processing cycle. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a processing method of a cylindrical thin-walled ring, which can improve the shortage of material waste and long processing cycle caused by the existing processing method. [0004] In order to solve the above technical problems, a technical solution adopted by the present invention is to provide a processing method for a cylindrical thin-wall...
