Embodiment Construction

[0012] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings through a preferred embodiment, but the protection scope of the present invention is not limited to the embodiment.

[0013] like figure 2 As shown, a method for processing a wear-resistant shaft sleeve, the main materials include an aluminum tube 1 and a steel tube 2 .

[0014] like figure 1 As shown, the aluminum tube 1 and the steel tube 2 are firstly pickled and dried. The specific expression is: when pickling the inner and outer surfaces of the aluminum tube 1, a dilute hydrochloric acid solution is used, the concentration range is 10% to 15%, and the temperature is 30- 40°C, pickled for 8-10 minutes, rinsed and placed in 2% NaNO 3 The solution is passivated, then blown with compressed air, and dried with steam; when pickling steel pipe 2, use dilute sulfuric acid solution with a concentration of 15%, set the temperature to 40-50 ° C, pic...

Abstract

The invention discloses a processing method for antiwear shaft sleeve pipe, wherein employed raw materials comprise an aluminium pipe and a steel pipe. The processing method comprises: performing acidpickling and drying on the aluminium pipe and the steel pipe; sleeving the steel pipe with the aluminium pipe, reserving 0.3 mm-0.4 mm of a gap between the aluminium pipe internal diameter and the steel pipe external diameter; employing a supersonic-frequency induction coil to heat the aluminium pipe and the steel pipe at the same time, tightly combining the heads of the aluminium pipe and the steel pipe by a special-purpose head rolling machine; lubricating the aluminium pipe and performing cold drawing by a speed-adjustable drawing machine. The shaft sleeve pipe produced by employing the processing method is not only excellent in thermal conductivity, but also improved in rigidity strength, and also aluminium material is substantially saved and the heat dissipation benefit is improved.

Description

technical field [0001] The invention relates to a production process of a composite pipe, in particular to a processing method of a wear-resistant shaft sleeve. Background technique [0002] Composite tubes are more and more widely used in our lives, and motors are also common in our lives. The long-term use of heat pipes for motor spindles are all aluminum tubes. Due to the high thermal conductivity of aluminum tubes, the heat dissipation effect is good. However, the aluminum tube used as the main shaft also has certain defects, that is, the rigidity is not enough, and it has no effect on short-term use, but it may cause some problems when used for a long time under heavy load. Such a composite tube that requires the overall structural rigidity of the radiator to be strengthened and the life of the main shaft to be extended has become a common demand for industrial production. [0003] Therefore, we continue to explore and research and develop in the production process, tr...
