Abstract

The invention discloses a machining die for a rotor of a brushless motor. The machining die comprises an upper die holder and a lower die holder, wherein an upper die plate is arranged on the upper die holder, a lower die plate is arranged on the lower die holder, and machining areas are formed on the upper die plate and the lower die plate respectively; two rows of locating columns are arranged on the portions, close to the edges on the two sides, of the upper die plate respectively, a row of first concave holes are formed between each row of locating columns and the machining area of the upper die plate, two rows of locating nails are arranged in the machining area of the upper die plate, and locating hole plunger chips are arranged between the machining area of the upper die plate and the feeding end; second concave holes, guide columns, third concave holes and locating hole feeding inlets are formed in the corresponding positions of the lower die plate. The machining die can achieve the purpose that the punching working procedure and the laminating working procedure are accomplished through a set of dies, production efficiency is improved, damage caused to semi-finished products in the process of movement among multiple working procedures is avoided, and product quality and machining accuracy of the rotor are guaranteed.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to a processing mold and a processing method for a brushless motor rotor. Background technique [0002] The rotor is the core component of the motor, and its processing technology is usually to punch out the rotor punching sheet with a mold first, and then laminate the rotor punching sheet to form the rotor. In the production process, the main defects that exist are: [0003] 1. The rotor punches punched out by the mold are stacked together, which is easy to be bumped and scratched, which affects the product quality of the rotor at the earliest; [0004] 2. During the stacking process, the rotor needs to be sorted and aligned again, which increases the workload; [0005] 3. The rotor processing requires multiple processes to complete, and the production efficiency is low; [0006] 4. In the punching process of the rotor sheet, the positioning of the steel belt is not ...
