Problems solved by technology

The traditional coiled bushing is made by a process of cutting large steel plates—cleaning—powder spreading and sintering—rolling—blanking and rolling, but the coiled bushings produced by this process are unstable in structure and long in service life. relatively short

Embodiment Construction

[0037] The following is attached figure 1 The present invention is described in further detail.

[0038] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contribution as required after reading this specification, but as long as they are within the rights of the present invention All claims are protected by patent law.

[0039] A processing method for a rolling shaft sleeve:

[0040] A. Cutting: Cut a large steel plate into small rough plates;

[0041] B. Rolling: Roll the blank plate after cutting, the rolling amount is 0.2-0.3mm (the rolling amount is 0.2mm, 0.25mm or 0.3mm);

[0042] C. Leveling: leveling the rolled rough plate once, so that the bent plate after rolling can be leveled;

[0043] D. Sanding: use sanding to polish the rough plate after leveling;

[0044] E. Cleaning: Use JQ-107 cleaning agent and ...

Abstract

The invention discloses a wrapped bearing bush processing method. A big steel plate is cut into multiple small blank plates, anti-rust oil on the blank plates is removed by means of a JQ-107 cleaning agent through ultrasonic cleaning, the cleaned blank plates are dried and then polished with sand paper, unleaded copper powder is spread on the polished blank plates, then the blank plates are placed in a sintering furnace to be sintered at 920-940 DEG C, and the rotating speed of a mesh belt in the furnace is 350-400 mm / min; the blank plates after primary sintering are rolled by 0.05-0.1 mm, and the leveled blank plates are placed in the furnace again for secondary sintering at 940-950 DEG C for 20-40 min, and the rotating speed of the mesh belt in the furnace is 350-400 mm / min; secondary rolling is conducted on the blank plates after secondary sintering by 0.02-0.04 mm, the blank plates after secondary rolling are punched, and the punched blank plates are rolled into the shape of a bearing bush. The wrapped bearing bush produced with the method is stable in structure, and the service life of the wrapped bearing bush is prolonged greatly.

Description

technical field [0001] The invention relates to the field of bearing processing, more specifically, it relates to a method for processing a rolled shaft sleeve. Background technique [0002] Bronze coiled bushings are made of specially formulated high-density copper alloy strips as the substrate, and the surface can be rolled with diamond-shaped or hemispherical oil holes and oil grooves according to user requirements. It has the advantages of high density, large bearing capacity, good wear resistance and long service life. It can replace the traditional cast copper sleeve, which can reduce the size of the machine and reduce the cost. It has been widely used in hoisting machinery, construction machinery, automobile tractor chassis, machine tool industry and mining machinery, and can also be made into bearing bushes, flanged bushings, thrust washers and ball bowls. The traditional coiled bushing is made by a process of cutting large steel plates—cleaning—powder spreading and...
