Novel rotor baking and shaping tool

Abstract

The invention discloses a novel rotor baking and shaping tool. The tool comprises a main frame, an upper mold and a lower mold; the upper surface of the upper mold is connected with a push rod of a lower pressing air cylinder, and the cylinder body of the lower pressing cylinder is connected with the main frame; a plurality of through grooves are formed in the upper mold, rectangular pressing blocks matched with the first through grooves are arranged right above the first through grooves, the upper surfaces of the rectangular pressing blocks are connected with a push rod of a lower pressing oil cylinder through a connecting rod, and the cylinder body of the lower pressing oil cylinder is connected with the upper surface of the main frame; and the connecting rod is sleeved with a replaceable limiting column, and the lower surface of the limiting column abuts against the upper surface of the main frame. According to the tool, when being shaped and pressed, firstly, the rotor is initiallyfixed through the lower pressing air cylinder, and then the lower pressing oil cylinder is started for pressing, so that the pressing time is greatly saved, and the pressing efficiency is improved; and through the replaceable limiting column, the thickness dimension of the rotor after being pressed can be controlled under the condition of lower cost (without the need for installing a sensor), sothat the manufacturing cost of a machine is saved.

Description

technical field [0001] The invention relates to a novel rotor baking and shaping tool. Background technique [0002] The internal core component of the electric motor is the stator-rotor assembly. The stator-rotor includes the stator and the rotor, and the surface of the stator or the rotor is also wound with coils. Existing stators and rotors are formed by stacking and welding several single pieces. Among them, stator lamination is used for stator lamination, and rotor lamination is used for rotor lamination. After the stator and rotor are laminated, their total thickness and flatness dimensions are often not up to standard, and shaping equipment is required for fine-tuning of dimensions and flatness modification. [0003] However, the traditional stator and rotor shaping tooling uses upper and lower punches for simple stamping. Its size is not easy to control, and the stamping force cannot be guaranteed to be uniform. After stamping, the flatness of the surface is often ...

Problems solved by technology

[0003] However, the traditional stator and rotor shaping tooling uses upper and lower punches for simple stamping. Its size is not easy to control, and the stamping force cannot be guaranteed to be uniform. After stamping, the flatness of the surface is often worse. In the traditional stator and rotor application field It can still be barely used, but with the increasing application of stator and rotor in the automotive field, the requirements for flatness and overall thickness are getting higher and higher, and the efficiency and quality of traditional shaping tools can no longer meet the current requirements. skills requirement
