Description

Technical Field

[0001] The utility model belongs to the field of cutting pouring risers and relates to a device which is convenient for cutting pouring risers. Background Art

[0002] A connector for a train needs to be cast due to its large size and volume. During the casting process, a riser is reserved for casting so that the molten alloy water enters the mold cavity through the riser and is then cast into a connector blank. After casting, the connector is taken out of the mold cavity after cooling for a period of time. Since there is space in the reserved riser, the cast alloy water will also form the shape of the riser, but the connector does not need this extra riser, so the extra riser needs to be cut off. Due to the large size and weight of the connector, the size of the riser is also large. The existing riser cutting is generally performed by workers using oxyhydrogen welding for cutting. This cutting method is costly and requires more pipes and wires, and the flatness of the cut is low. It is difficult to cut off a large riser with a small cutting machine. Therefore, in order to solve the above technical problems, the technical solution of the present application is provided. Utility Model Content
