Stainless steel embedded sleeve

Abstract

The invention discloses a stainless steel embedded sleeve. The stainless steel embedded sleeve comprises a main body, wherein the main body comprises an anti-pulling device and a sleeve which are integrally formed and manufactured; a central hole is formed in the sleeve; an internal thread is arranged at one end of the central hole; the anti-pulling device is arranged at one end, far away from the internal thread, of the sleeve; and the ratio of the height of the anti-pulling device to the outer diameter of the sleeve to the height of the main body is (1.2-2): 1: (2.5-5). According to the stainless steel embedded sleeve, the anti-pulling device and the sleeve are integrally formed, the structure is simple, the processing is convenient, and the production efficiency can be effectively improved. In addition, the height of the anti-pulling device, the outer diameter of the sleeve and the height of the main body are limited, so that the maximum limited axial drawing force can be guaranteed, and the strength of the stainless steel embedded sleeve can be guaranteed to meet the mechanical requirements of pulling resistance and rotary shearing.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a stainless steel embedded sleeve. Background technique [0002] With the development of the rail transit industry, the pre-buried channel has also been widely used. During the use of the channel, if it is damaged or corroded, it cannot be replaced, and the full-ring installation also causes waste. Installation is also problematic. Due to the need for deflection correction and turning, the segment cannot be installed according to the theoretical position during installation, which causes the misalignment of the embedded channel and brings great inconvenience to the subsequent installation of electromechanical equipment. Therefore, most of the prior art adopts embedded sleeves to realize the installation of the channels. [0003] However, the pre-embedded sleeve in the prior art is processed by forging, rust removal, heating, forging forming, positioning, drilling, tapping, ...

AI Technical Summary

Problems solved by technology

[0003] However, the pre-embedded sleeve in the prior art is processed by forging, rust removal, heating, forging forming, positioning, drilling, tapping, sand blasting, solid solution, post-treatment and other procedures after cutting off the stainless steel rod. The processing procedures are complicated, and most of them are produced by manual stand-alone machines, and the production efficiency is low.
