Problems solved by technology
[0010] However, for the third production structure mode, there has been no successful report on realizing the nesting of the rotor and the stator on the same strip material, especially in the setting of the punching station, the arrangement of the punching station, the rotor and the stator. There are still many technical problems that need to be solved in many aspects such as the sleeve cutting (cutting) of the finished rotor and the stator shaft hole.

Abstract
The invention discloses a motor lamination riveting rotor and stator grading punching folding device. The device is metal molds comprising an upper convex mold, an unloading plate which is elastically provided with a working surface of the upper convex mold and a lower concave mold. The upper protruded mold, the unloading plate and the lower concave mold are made by a common technical scheme, match to each other and work in a combination mode according to a processed workpiece technology requirement. The metal molds are arranged along a length direction and are located on a same axis. A lamination rotor punching folding working portion and a lamination stator punching folding working portion are successively and continuously arranged. Under a working condition, the metal molds sequentially and continuously carry out sleeve cutting punching of the rotor and the stator and lamination riveting work on a grading processed workpiece; and manufacturing of a lamination stator and a lamination rotor is completed at front and back positions respectively. The device possesses characteristics that the structure is reasonable; the rotor and the stator carry out combination cutting; shaft hole cooperation precision of the rotor and the stator is high; production efficiency is high; a material utilization rate is high and so on. The device of the invention is especially suitable for stepping motor lamination rotor and stator manufacturing.
Description
technical field [0001] The invention relates to a motor lamination riveting rotor stator progressive stamping device, which belongs to the technical field of motor production. Background technique [0002] The motor described in the present invention mainly refers to a functional motor, especially a stepping motor. [0003] The rotor and stator of the stepping motor are all made of thin steel strips (such as silicon steel strips), punched into single pieces, and then laminated by single pieces. [0004] The lamination of the single sheets mainly includes riveting and bonding, and the lamination of the present invention is riveting. [0005] The riveting of the laminations is to stamp the corresponding parts of the laminations into pits (that is, one side is a protrusion and the other side is a depression), and then the corresponding pair of protrusions and depressions of the adjacent laminations form a concave-convex pair, Stamped and riveted together. [0006] There are ...
