Problems solved by technology

The mold usually used in the industrial production of the rotor sheet of the motor rotor is a single-process stamping mold. , coil winding and other follow-up processes, therefore, this kind of mold cannot be continuously produced with strip materials, the production efficiency is low, and it consumes a lot of manpower and material resources, which increases the production cost; because multiple sets of molds are used for stamping, the tolerance of each process is not easy to control, The quality of the rotor is poor, and then a bad motor is produced; on the other hand, the existing motor rotor is composed of several rotor pieces that are simply overlapped, which is easy to loosen, and the magnetic permeability is reduced, making the speed of the motor unstable.

Abstract

The invention discloses a progressive stamping die of a motor rotor. The progressive stamping die of the motor rotor comprises an upper die body and a lower die body. An upper mounting plate of the upper die body is provided with a first punch column and a second punch column which are arranged in parallel in the feeding direction. Punches in the first punch column and punches in the second punch column are staggered, and the center-to-center distance between the first punch column and the second punch column is smaller than the diameter of the motor rotor. A lower die plate of the lower die body is provided with a first die cavity column and a second die cavity column in the feeding direction. The first die cavity column and the second die cavity column correspond to the first punch column and the second punch column respectively. The progressive stamping die of the motor rotor is high in production efficiency and low in manufacturing cost.

Description

technical field [0001] The invention relates to the field of progressive stamping dies, in particular to a progressive stamping die for a motor rotor. Background technique [0002] With the development of industry, the use of motors is increasing, and accordingly, the demand for motor rotors is also increasing. The mold usually used in the industrial production of the rotor sheet of the motor rotor is a single-process stamping mold. , coil winding and other follow-up processes, therefore, this kind of mold cannot be continuously produced with strip materials, the production efficiency is low, and it consumes a lot of manpower and material resources, which increases the production cost; because multiple sets of molds are used for stamping, the tolerance of each process is not easy to control, The quality of the rotor is poor, and then a bad motor is produced; on the other hand, the existing motor rotor is composed of several rotor pieces that are simply overlapped, which is ...
