Embodiment 1

[0033] Such as figure 2 , image 3 Shown, a kind of manufacturing method of new sealing ring steel skeleton is characterized in that it is realized through the following steps:

[0034] (1) Select 45# seamless steel pipe, and cold draw the selected steel pipe through a cold drawing machine so that the outer diameter of the steel pipe meets the design requirements of the steel skeleton of the sealing ring, that is, the outer diameter of the steel skeleton of the sealing ring is Φ=39.9mm, and the steel pipe The inner diameter of the inner diameter is 28.7mm, which includes the machining allowance of the subsequent process;

[0035] (2) Saw and cut the drawn steel pipe on a sawing machine to form a ring-shaped blank. The height of the obtained ring-shaped blank is 6.5mm, and this height contains the machining allowance of the subsequent process;

[0036] (3) putting the ring-shaped blank obtained by cutting into the drum of the roller machine and rolling it, and removing the s...

Embodiment 2

[0043] Such as figure 1 , image 3 Shown, a kind of manufacturing method of new sealing ring steel skeleton is characterized in that it is realized through the following steps:

[0044] (1) Select 40Cr seamless steel pipe, and cold draw the selected steel pipe through a cold drawing machine, so that the inner diameter of the steel pipe meets the design requirements of the steel skeleton of the sealing ring, that is, the inner diameter of the middle part of the steel skeleton of the sealing ring Φ 2 = 27.5mm, the outer diameter of the steel pipe is 38.1mm, and the outer diameter includes the machining allowance of the subsequent process;

[0045] (2) Saw and cut the drawn steel pipe on a sawing machine to form a ring-shaped blank. The height of the obtained ring-shaped blank is 6.5mm, and this height contains the machining allowance of the subsequent process;

[0046] (3) putting the ring-shaped blank obtained by cutting into the drum of the roller machine and rolling it, and...

Abstract

The invention belongs to the field of mechanical manufacture, and it relates to a method for preparation of annular- seal steel skeleton, which contains: cold dragging the steel pipe with cold drawing machine, sawing on the saw machine, tumbling with cylinder device, and turning by four times with a lathe. The invented technique is simple, and the cost is low while the quality is perfect, and it has a good market outlook.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and relates to a new manufacturing method of a sealing ring steel skeleton. Background technique [0002] The existing sealing ring steel frame is used in a large amount, and the traditional manufacturing method is produced by powder metallurgy process, and the process is powder mixing, material mixing, pressing, sintering, and post-treatment. Therefore, the process is very complicated, and expensive supporting molds are required, so the production cost is high; at the same time, due to the low strength of the sealing ring steel skeleton produced by the powder metallurgy process, it is easy to be damaged and has a short service life, which causes the machinery using the sealing ring steel skeleton to run It is very prone to failure in the middle, which seriously affects the product quality of the manufacturer. Contents of the invention [0003] The purpose of the present invention is to ov...
