[0002] Cut wire shot is a kind of metal abrasive used in the process of shot peening. It is widely used in the field of metal surface treatment in industries such as aerospace, automobile, military industry, wind power, automobile, high-speed rail, shipbuilding, medical equipment, etc. It can improve the surface mechanical properties of metal workpieces and improve the surface integrity of parts. Cutting shot is to cut cold-drawn new steel wire or waste recycled steel wire into cylindrical particles with a length-to-diameter ratio close to 1, and the cutting is completed by the relative movement of the cutter and the steel wire. The quality of cut wire shot is particularly important for the shot peening effect, so only a good-performance and high-efficiency cut wire shot machine can meet the needs of abrasive production.

[0003] For example, a wire shot cutting machine with patent number CN202020613628.X includes a wire feeding roller, a pressure wheel, an elastic component and a wire cutting mechanism. At least two pressure wheels are arranged side by side along the axial direction of the wire feeding roller, and each pressure wheel is connected to an elastic component. The elastic component pushes the pressure wheel to press the wire feeding roller. The wire feeding roller is connected to a power device for driving it to rotate. The wire cutting mechanism is arranged on the wire output side of the wire feeding roller, and an adjusting device for adjusting the pressure between the pressure wheel and the wire feeding roller is arranged between each pressure wheel and the wire feeding roller.

[0004] However, this structure has the following problems: first, the wire cutting mechanism is complicated and the manufacturing cost is high; second, the pressure wheel is separated from the wire feeding roller, which increases the space and the number of parts, thereby increasing the manufacturing cost; third, the wire cutting distance needs to be adjusted manually, which is inefficient.
