Abstract

The invention relates to a female die processing technology in a stator punching sheet large and small groove single-punching die, belongs to the technical field of stator punching sheet single-punching die processing, and solves the technical problems that the precision cannot be ensured by traditional one-time linear cutting, the punching quality and efficiency of a punching sheet are influenced by unstable control and the like. According to the solution, the female die machining technology in the stator punching sheet large-small groove single-punching die comprises the steps that (1) a large-groove female die insert is fixedly arranged in a first groove hole, and a small-groove female die insert is fixedly arranged in a second groove hole; (2) a large-groove wire penetrating hole is machined in the large-groove female die insert fixedly installed in the step (1), and a small-groove wire penetrating hole is machined in the small-groove female die insert; and (3) a wire cutting machine is used, the female die machined in the step (2) is arranged on the wire cutting machine, and cutting of a large groove and a small groove is conducted. By means of the cutting mode of cutting once and trimming twice of the wire cutting machine, the machining precision of the female die is improved, the surface smoothness of the die is guaranteed, and the machining efficiency can be greatly improved in the machining process of large and small stator groove single-punching dies in batches.
