Description

Technical Field

[0001] The utility model belongs to the technical field of cutting railway scrapped freight car wheels, in particular to an auxiliary positioning tool used for sawing machines to cut railway wheels. Background Art

[0002] The recycling of scrapped railway freight cars is an important link, which not only involves resource reuse and environmental protection, but also relates to the sustainable development of railway freight. Scrapped railway wheels need to be cut and disassembled for processing, usually using sawing equipment to evenly cut them into multiple petals along the center line for further processing.

[0003] In the prior art, when a sawing machine cuts a wheel cake, a support seat is set at its lower part as an overall support; the support seat is usually a complete pad. After the railway wheel cake is cut, the cut wheel petals fall on the pad for support to prevent them from falling from both sides, making it convenient for the next step of cutting; however, this will cause the saw blade of the sawing machine to scratch the lower support seat when completing the cutting of the wheel cake. If the number of scratches increases, it will not only be detrimental to the stability of the upper wheel support, but also require frequent replacement of the support seat, which increases costs and reduces efficiency.
