The invention relates to a machining method of a large and medium-size motor stator-rotor silicon steel sheet. The method comprises the following processes of: cutting a roll material; blanking and drawing mark lines on stamped sheets; rotating and piling the stamped sheets and eliminating intra-plate deviation; stamping mark slots and rotator closed keyways on stator stamping sheets; stamping slot shapes of the stator stamping sheets and inner circles; expanding dummy spindle holes of rotor stamping sheets; and stamping slots on the rotor stamping sheets. Compared with the traditional machining method of the large and medium-size motor stator-rotor silicon steel sheets at present, the invention has the advantages of high production efficiency, good intra-plate devication elimination effect and high raw material utilization rate.
Description
Technical field
The present invention relates to a kind of large and middle size motor stator-rotor silicon steel sheet processing method.
Background technology
At present, large and middle size motor stator-rotor silicon steel sheet traditional diamond-making technique, its technological process is basically: open billot; The billot number of marking; Turnover panel, it is poor with plate to eliminate; Blanking; Go out the stator punching cylindrical, the aperture is greater than rotor punching dummy shaft hole and the keyway of φ 35; Towards stator punching flute profile and interior circle; Expand the sub-punching dummy shaft of red switch hole, go out true axis hole; The sub-punching flute profile of red switch.There are three big defectives in large and middle size motor stator-rotor silicon steel sheet processing method at present:
For satisfy open billot after billot to make 180 ° of turnover panels, eliminate technological requirement with the plate difference, its raw material can not be used coiled strip, can not use automatic assembly line production, production efficiency is low;
Billot use 180 ° of turnover panel methods eliminate with plate poor, the one, the same plate that can only eliminate rectangle billot two symmetrical limits is poor, and the same plate difference on the other two symmetrical limits of rectangle billot exists, and eliminates weak effect with the plate difference, influences the technology acuracy after the moulding of large and middle size motor stator-rotor silicon steel sheet lamination; The 2nd, labor strength is big, and production efficiency is low;
3. expand the clout of punching footpath greater than the rotor punching dummy shaft hole gained of φ 35, value is low, the production cost height.
Summary of the invention
For solve the existing production efficiency of large and middle size motor stator-rotor silicon steel sheet traditional diamond-making technique low, eliminate weak effect, labor strength is big, production cost is high deficiency with the plate difference, the invention provides a kind of large and middle size motor stator-rotor silicon steel sheet processing method, this processing method can solve the existing deficiency of large and middle size motor stator-rotor silicon steel sheet traditional diamond-making technique well.
The technical scheme technological process that technical solution problem of the present invention is adopted is: material left by coiled strip; Blanking, mark line is drawn in punching; The punching rotor stacks, and it is poor with plate to eliminate; Towards stator punching mark groove and the rotor keyway of remaining silent; Towards stator punching flute profile and interior circle; Expand the sub-punching dummy shaft of red switch hole; The rotor punching jet-bedding.
Material left by coiled strip described in this technological process, is to use automatic cutting machine coiled strip is sheared continuously automatically, and institute's billot of opening and clout furl again automatically, and the billot after the rolling can carry out the automatic press blanking for the automatic blanking machine.
The described punching rotor of this technological process stacks, and eliminating with the plate difference is to be foundation with the mark line, and per 10 is one group, and every group is rotated once, and rotational angle is followed successively by 90 °, 180 °, 270 °, 360 °, repeats above-mentioned rotor process then successively, and it is built up heap.It is poor with plate that the process that this rotor stacks can be eliminated in 360 ° of scopes.
Blanking described in this technological process is that once to go out stator simultaneously be the rotor punching dummy shaft hole of φ 35 towards cylindrical and aperture, expands at last towards the true axis hole of main rotor punching.Less because of φ 35 apertures, the waste utilization rate height under it expands.
The invention has the beneficial effects as follows: can use automatic producing device production, the production efficiency height; It is poor with plate that application rotor mode is eliminated in 360 ° of scopes, eliminates effective with the plate difference; Waste utilization rate height saves material.
