Spinning fixture for manufacturing deep groove split spinning belt pulley and application of spinning fixture

Abstract

The invention discloses a spinning fixture for manufacturing a deep groove split spinning belt pulley and application of the spinning fixture. A mandrel clamp for clamping a plate is arranged on a spinning device, a split spinning roller is arranged on a first spinning roller shaft, a molding spinning roller is arranged on a second spinning roller shaft; and the split spinning roller, the molding spinning roller and the plate clamped by the mandrel clamp are corresponding arranged. According to the invention, a split spinning process is divided into two steps comprising manufacturing processes of the split spinning roller and the molding spinning roller, and the split spinning roller is in charge of splitting and pre-molding tasks. The split spinning roller comprises a split point, a flange and a corrugated belt, wherein the split point can reduce the flowing resistance of the plate in a split spinning process, thus the spinning stability is increased and the split deflection is avoided; the flowing speed of the plate is controlled through the flange, thus local thickening is realized, and product strength is increased; and the corrugated belt mainly avoids clamping the spinning roller due to the rebounding of raw materials in the split spinning process, and reducing slot finish of the product due to the adhesion caused by mutual friction under the condition of high-speed rotation. The spinning fixture has the advantages of stable performance, difficulty in spit deflection, and good spinning effect.

Description

technical field [0001] The invention belongs to the technical field of plate spinning belt pulley processing and relates to a split spinning device. Background technique [0002] At present, more and more split structures are used in V-shaped spinning pulleys in automobiles, motors, and agricultural machinery, because compared with other methods, the split structure: less material consumption, less process, simple mold, high efficiency, and high performance it is good. However, the split structure has higher requirements on the spinning process, and it is prone to splitting deviation during spinning, resulting in uneven thickness of the working part, especially the deep groove split spinning pulley. [0003] At present, one spinning wheel is used to complete the splitting and forming of the split spinning pulley, which can meet the requirements when processing the shallow groove split spinning pulley, but when processing the deep groove split spinning pulley, the deeper the...

Problems solved by technology

However, the split structure has higher requirements on the spinning process, and it is easy to appear splitting deviation during spinning, resulting in uneven thickness of the working part, especially the deep groove split spinning pulley

[0003] At present, one spinning wheel is used to complete the splitting and forming of the split spinning pulley, which can meet the requirements when processing the shallow groove split spinning pulley, but when processing the deep groove split spinning pulley, the deeper the groove depth is, that is The longer the cantilever of the sheet beyond the pressing surface of the upper and lower core molds, the worse the rigidity. During spinning, it is easier to lose stability with the feeding of the rotary wheel, resulting in splitting. As the rotary wheel continues to feed, it may cause the sheet to rupture
