Embodiment Construction

[0011] The present invention will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention.

[0012] Such as figure 1 The shown forging production method of a spacer ring includes the following processes carried out in sequence: blanking, heating, upsetting, punching and reaming, ring rolling, and normalizing.

[0013] Such as figure 2 As shown, the normalizing is composed of heating stage, first heat preservation stage, cooling stage, second heat preservation stage and cooling stage. The first heat preservation stage is 880°C for 75 minutes, and the second heat preservation stage is 450°C for 150 minutes.

[0014] The heating stage is heating to 880°C for 30 minutes. The cooling stage is divided into two stages: the first cooling stage is 7min to 500°C, and the second stage is 90min to 450°C. This cooli...

Abstract

The invention discloses an isolating ring forging production method. The isolating ring forging production method sequentially comprises the steps of feeding, heating, upsetting, punching and chambering, ring rolling and normalizing. The normalizing step is composed of the heating stage, the first heat preservation stage, the temperature decreasing stage, the second heat preservation stage and the cooling stage in sequence. The first heat preservation stage lasts 75 min at the temperature of 880 DEG C, and the second heat preservation stage lasts 150 min at the temperature of 450 DEG C. The whole process is simple, the performance of manufactured products is good, and the hardness reaches HB157-220.

Description

technical field [0001] The invention relates to the technical field of spacer ring processing, in particular to a forging production method of spacer rings. Background technique [0002] The spacer ring is a typical thin-walled annular part. Due to its thin wall thickness, it is easily deformed under the action of clamping force. Therefore, it is difficult to guarantee the design accuracy of the part, which seriously affects the assembly quality of the part. How to reduce deformation of such thin-walled ring parts in mass production, improve the stability of part quality and processing efficiency is a common problem. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention proposes a forging production method of the spacer ring, which is easy to operate and simple in process. [0004] In order to achieve the purpose of the above invention, the present invention provides the following technical solutions: a forging production method for...
