Abstract
The invention discloses a frequency conversion motor symmetric cutting type iron core and a machining technology. The frequency conversion motor symmetric cutting type iron core is formed by overlaying a plurality of iron core punched sheets. Each iron core punched sheet is composed of a plurality of single punched sheet bodies connected end to end. Each single punched sheet body comprises a plurality of single stator yoke bodies formed by conjoining stator yokes. Each stator yoke is provided with a stator tooth, wherein the inner sides of the two ends of the stator tooth are provided with grooves. A bent groove is formed between every two adjacent stator yokes. A tenon is arranged at one end of each single stator yoke body, and a mortise is formed in the other end of each single stator yoke body. The machining technology comprises the steps that strips are fed into a punching machine after being uncoiled and flattened, the punching machine punches each strip to form two oppositely-staggered single punched sheet bodies, meanwhile, the grooves are punched in the inner sides of the two ends of the stator teeth of each single punched sheet body, the multiple single punched sheet bodies are welded end to end to form the iron core punched sheets, and the iron core punched sheets are overlaid to form the iron core. According to the frequency conversion motor symmetric cutting type iron core and the machining technology, materials can be greatly saved, the machining steps can be simplified, and the product quality is ensured.
Description
Technical field
The present invention relates to a kind of external rotor electric machine field, particularly a kind of variable-frequency motor symmetry division formula iron core and processing technology.
Background technology
External rotor direct current variable frequency motor, its stator core is made up of stator punching.In traditional processing method, stator core is overrided to form by stator punching, and stator punching is directly by punching of the steel plate circlewise, namely stator punching is domain punching, and we know, the core of stator punching is provided with the centre bore that power supply machine output shaft wears, like this, the annular stator punching of every punch process, all to wash out the round plate that one piece of external diameter equals centre bore internal diameter on steel plate raw material, thus make the raw-material utilance of steel plate extremely low, greatly waste material, thus make the manufacturing cost of motor also just higher.
Summary of the invention
The object of the invention is to, a kind of variable-frequency motor symmetry division formula iron core and processing technology are provided.The present invention can save material greatly, can also simplify procedure of processing, ensures product quality.
Technical scheme of the present invention: variable-frequency motor symmetry division formula iron core, comprise and being made up of multiple core stamping superposition, it is characterized in that: the punching monomer that described core stamping is connected by multi-disc head and the tail is formed, punching monomer comprises the stator yoke monomer of multiple stator yoke disjunctor, described each stator yoke is provided with stator tooth, and stator tooth is provided with groove inside two ends, is provided with bending groove between described stator yoke is adjacent, described stator yoke monomer one end is provided with tenon, and the other end is provided with tongue-and-groove.
In aforesaid variable-frequency motor symmetry division formula iron core, described groove is wide is 1.0-2.8mm, is 0.4-1.2mm deeply.
In aforesaid variable-frequency motor symmetry division formula iron core, the punching monomer that described core stamping is connected by three head and the tail is amounted to into full circle and is formed.
In aforesaid variable-frequency motor symmetry division formula iron core, described punching monomer comprises the stator yoke monomer of six stator yoke disjunctors.
According to the processing technology of aforesaid variable-frequency motor symmetry division formula iron core, punch press is sent into after billot uncoiling being flattened, punch press is gone out the punching monomer that two staggered relative are arranged, inside the stator tooth two ends of punching monomer, go out groove simultaneously, this punching monomer of some head and the tail welding is formed core stamping, after core stamping superposition, forms iron core.
Compared with prior art, the present invention is connected and composed by punching monomer head and the tail, coordinate the structures such as bending groove, tenon, tongue-and-groove simultaneously, the mode can carrying out vertical bar punching is shaping, and two the punching monomers be arranged symmetrically with can be formed, thus substantially increase raw-material utilance, save material, reduce production cost.And by arranging groove inside stator tooth, when mold notch is to when cutting, can not leave waste material wedge angle in punching, centre does not have scrap (bridge), thus again need not process punching, simplifies procedure of processing, can also ensure product quality.The present invention also has enforcement structure feature simple and easy to use.
