AI Technical Summary

Problems solved by technology

When spinning large rim pulleys, a large amount of material needs to be split or thickened. The spinning force of the existing spinning machine is too small to realize the spinning of a large amount of materials, and it is also impossible to apply the spinning process to produce large rims. pulley

Embodiment Construction

[0021] The specific implementation manner of the present invention will be further described in detail below by describing the embodiments in conjunction with the accompanying drawings.

[0022] A method for processing a belt pulley, comprising the steps of:

[0023] A. Cutting material: punch out the via hole 11 in the middle part of the circular plate blank to form the ring plate material 10 .

[0024] B. One-time molding: the outer plate body of the central circular area of ​​the ring plate 10 is folded to one side of the plate surface to the angle between the plate surfaces on both sides of the junction is β, 0<β<90°, and the composition includes the inner side The bottom wall 21 and the outer side wall 22 are shallow basin-shaped blanks 20 . One-time forming can be formed by stamping process.

[0025] C. One-time welding: the via hole 11 in the middle of the shallow basin-shaped blank obtained in step B is set in the middle of the tubular hub 30 for welding, and the out...

Abstract

The invention belongs to the technical field of machining, and particularly relates to a belt pulley machining method which achieves spinning machining of a large-rim belt pulley rim in a breakthrough mode, the number of needed spinning dies is small, and research and development investment is small. The wheel body machining steps are simple, the production efficiency is high, and the forming effect is stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, in particular to a method for processing a pulley. Background technique [0002] Pulleys with large rims are usually made of cast iron, and pulleys with small rims are usually forged with steel. The blanks produced by casting or forging processes need to be processed by rough turning and finishing turning, which will remove a lot of scrap and material loss. Large, high energy consumption and low production efficiency. [0003] Spinning is a process in which flat or hollow blanks are fixed on the mold of the spinning machine, and while the blank is rotating with the main shaft of the bed, the blank is pressed with a spinning wheel or a driving rod to cause local plastic deformation. At present, the belt pulley produced by the spinning process has a thinner wall thickness than the cast belt pulley, and has the advantages of low cost, light weight and long service life, and has been w...
