Technical field
The present invention relates to the punching manufacturing processing technic field of motor rotor, be specifically related to a kind of manufacturing process of conical rotor motor punching.
Background technology
At present, conical rotor motor has the characteristic that is different from conventional cage rotor motor, and this motor carries brake gear; During energising; Rotor play forward under the effect of axial magnetic field, thus brake opened, when dump, stop operating rapidly; Be widely used at present in the wherein Transport Machinery of industries such as building, metallurgy, also can be used for controlling automatically special place or the plant equipment that requirements such as streamline can be braked rapidly.
But; Because the particularity of conical motor; Be that stator inner hole, rotor diameter are taper; Every chip size has nothing in common with each other, and the punching manufacturing process that prior art adopted is: the silicon steel sheet lath that utilizes a large-tonnage punch press to cut into two exact halves carries out the blanking of stator cylindrical and rotor inner hole, respectively stator is carried out jet-bedding, rotor burst and rotor jet-bedding through the mode of three single groove-punching groove machine combinations then.Every rotor silicon steel sheet all needs to carry out calibration, progressively moulding of the feeding of traverse feed ratchet through single groove-punching groove machine rotating shaft bottom chain wheel.Through this manufacturing process, belong to single-piece production, equipment precision is not high, and the mould adjustment is complicated; Thereby the rotor width of rebate that processes differs, and stator inside and outside circle concentricity is poor, and burr height surpasses 0.05mm, and regularity is poor behind the lamination; The sheet that rises is serious, and exciting curent increases, and eddy-current loss increases; Noise increases, the heat radiation difficulty, and power reduces.And, can't form production in enormous quantities.
Therefore, the existence of these problems and defective affects the development in Chinese conical rotor machine market to a certain extent.
Summary of the invention
For solving the defective of above-mentioned manufacturing process, the invention provides a kind of suitable production in enormous quantities, equipment precision height, save energy and reduce the cost, increase work efficiency, the manufacturing process of the conical rotor motor punching that reduce workman's operation intensity, reduces cost.
In order to solve the problems of the technologies described above, the manufacturing process of conical rotor motor punching provided by the invention is to adopt following technical scheme to realize:
A kind of manufacturing process of conical rotor motor punching, the processing step that is adopted is:
1) feeding: the silicon steel sheet billot that slitting is good is installed on the double end bin, gets into feeder through S shape level(l)ing machine;
2) punching press: each group progressive die is installed in and forms stamping line on the high velocity ram machine, and billot gets into high velocity ram machine through feeder, carries out continuous punching press through progressive die, realizes the rotor punching that the multi-disc size is different and the blanking of stator punching.
Described progressive die comprises mould body; Mould body is divided into upper die and lower die, and upper die and lower die are divided into 5 step pitches, is respectively first step distance, second step pitch, the 3rd step pitch, the 4th step pitch, the 5th step pitch; Be set to rotor jet-bedding station on the said first step distance; Second step pitch is provided with rotor blanking station, and the 3rd step pitch is provided with stator jet-bedding station, and the 4th step pitch and the 5th step pitch are provided with stator blanking station.
The described first step is the 4-10 sheet apart from the rotor core grooved of punching out.
Described second step pitch is with the rotor sheet blanking of the first step apart from punching out.
The stator grooved of described the 3rd step pitch punching out is the 2-5 sheet.
The remaining stator grooved of described the 4th step pitch punching out is the 2-5 sheet, and the stator piece of the 3rd step pitch punching out is carried out blanking.
Described the 5th step pitch is with the stator piece blanking of the 4th step pitch punching out.
The present invention adopts such scheme, and its beneficial effect is: this manufacturing process can realize the integrated continuous punching out of rotor, through one time punching molded rotor; In use have good uniformity, the stator rabbet that punching out is come out is neat, and burr height is less than 0.02mm; Flatness is high; Almost do not have the sheet of rising, reduce exciting curent and eddy-current loss to greatest extent, hoisting power.And steady quality, simultaneously, reduce manufacturing cost, alleviate labor strength, energy-saving and cost-reducing, improved operating efficiency, easy to operate, practical, be suitable for and produce in enormous quantities.
