Rotary pressing tooling for manufacturing asymmetric T-shaped rotary pressing belt wheels

Abstract

The invention relates to a rotary pressing tooling for manufacturing asymmetric T-shaped rotary pressing belt wheels. An upper core mold and a lower core mold are arranged on rotary pressing equipment, a T-shaped thickening rotary wheel, a flat rotary wheel, a preforming tooth rotary wheel and a final forming tooth rotary wheel are respectively arranged on respective rotary wheel shafts, each rotary wheel and the upper and lower core molds are in corresponding arrangement, the work surface of the T-shaped thickening rotary wheel is provided with a groove, and the groove corresponds to a plate material tightly clamped by the upper core mold and the lower core mold. Materials are regulated to uniformly flow towards two sides according to proportions through the contact area between the circular arc of the groove and the material, the material flowing speed is also limited by the groove, the extrusion on the materials is also enhanced in the stack rotation process, the compactness is realized, the cracking and delamination possibilities are reduced, and the forming stability is improved. The flat rotary wheel is mainly used for continuously pushing distributed materials until the inner walls at two T-shaped sides are fully pasted with the upper core mold and the lower core mold through feeding. The rotary pressing tooling has the advantages that the processing process is stable, the rotary pressing effect is good, and conditions of folding, delamination and fracture of the materials cannot occur in the forming process.

Description

technical field [0001] The invention belongs to the technical field of plate spinning belt pulley processing and relates to a spinning forming device with an asymmetrical T-shaped structure. Background technique [0002] At present, more and more T-type spinning pulleys are used in automobile engines, because compared with other methods, T-type structure: less material consumption, less process, simple mold and high efficiency. The T-shaped structure is not only compact, but also has better relative strength because there is no stress concentration point, which not only expands the practical application range. [0003] With the continuous deepening of environmental protection and energy-saving requirements in the automotive industry, the engine is obviously tending to be lightweight and miniaturized. Arranging hundreds of parts in the limited engine layout space, while the functions continue to increase, many parts must be shaped. The asymmetrical T-shaped pulley is a form...
