Brief analysis of steel connecting sleeve process
Provider： Source：Baoding Jindi Machinery Co., Ltd Time：2019-04-11
There are four main methods for connecting steel sleeves. (1) According to the different blanks, they are directly cut into blanks by seamless tubes, and then drilled into blanks after blanking. The billet and the billet are billed. Among them, the calcination and cold extrusion into the blank are special because of the special processing steps, it is difficult to ensure that the pore size and concentricity of the formed tube are consistent, so there are many problems for the subsequent tapping.
(2) According to the processing flow, the processing of the steel connecting sleeve is also different according to the characteristics of the blank. It is mainly divided into two types of processing steps (mainly in the processing of chamfering and outer circle (peeling)). Different), tapping can be done in the same way.
The first is a blank that is drilled with a seamless tube blank and a bar. This type of blank is relatively uniform due to its concentricity and the size of the inner hole, and the end faces are relatively flat, so the outer and outer corners of the car can be completed on the same machine (the chamfering machine with chamfering function) The processing of the end face and the chamfering of the inner hole, but according to the requirements of different customers, ultimately decide whether it is necessary to re-process.
The second is mainly for cold extrusion and forging forming blanks. Because the biggest feature of the two blanks after forming is that the length of the blank is different, and the end face after forming is uneven. Moreover, the inner hole also has a large degree of difference. As the mold continues to wear, the size and concentricity of the inner hole will also appear to be different degrees of eccentricity and smaller aperture. In this case, this type of blank is usually machined with a special steel connecting sleeve chamfering machine for the inner corner and the outer corner. Then it is processed by a special external circular machine with a special steel connecting sleeve. The main feature of these two devices is the development of the steel connecting sleeve. So the fit is very good. The tapping of the latter process also has a certain improvement effect.
