Abstract
The invention provides a conical rotor motor multi-column malposition punching piece blanking technology. The technology comprises the steps of rolled material unreeling leveling feeding, high-speed punching, multi-column malposition grading die blanking and stator-rotor punching piece (and by-product) producing in sequence. The multi-column malposition punching piece blanking technology is used, an automatic feeding technology is used in production for reducing the strip material width, the workpiece feeding step distance and workpiece technology scrap allowance, the material using rate can be improved by 1-1.5%; a malposition technology is used, effective area is fully used, the strip material width is saved, the effective piece-out rate is improved by about 711%; a multi-column single blanking technology is used in a die, material layout combination is optimized, width loss is lowered, the blank comprehensive rate is improved, and the strip material strip-forming rate can be improved by about 24%, and meanwhile spaces between circles are used for producing stator-rotor punching pieces, by products are produced at the same time, material comprehensive utilization is improved and is about 411% of the total utilization rate; working efficiency during a production process is improved, the production quality of products is improved, the service life of the die is prolonged, production cost is lowered, and production safety guarantee is improved.
Description
Technical field
The present invention relates to ZD, ZDY series conic rotor braking motor and BZD, BZDY series flame-proof type conic rotor braking electric motors.Be specifically related to a kind of conical rotor motor multiple row dislocation punching blanking process.
Background technology
At present, motor industry, when selecting motor with material-silicon steel sheet, along with country actively promotes cold-reduced silicon sheet, is prohibited the policy of production hot rolling silicon tablet and is further implemented, and two kinds of silicon steel sheet price differences further dwindle and approach, " hot with cold generation " become natural trend.But cold-reduced silicon sheet is with regard to manufacturing motor stator rotor core, adopt traditional punching blanking process, at aspects such as stock utilization, piece rate, rolled twig rate, by-product utilization rate and operating efficiency, product quality, lives of product, all there is great technical problem, cause the inconvenience in the wasting of resources and the manufacturing, use.
Therefore, the present invention develops on the basis that mainly solves more than currently available technology existence deficiency.
Summary of the invention
Technical problem solved by the invention is to provide a kind of multiple row dislocation punching blanking process; Improve stock utilization, production work efficiency, the conical rotor motor multiple row dislocation punching blanking process that reduces motor cost, extends die life.
Based on above-mentioned purpose, technical problem solved by the invention realizes by the following technical solutions:
A multiple row dislocation punching blanking process, described processing step is: coiled strip unreels smoothing feeding → high velocity ram machine → multiple row grading blanking die → rotor punching (and byproduct) output that misplaces.
The same model punching of described motor cylindrical is identical with axis hole.
Described stator core inner circle and rotor outer circle be taper shape, cone angle scope is 9 ° of 15'--28 ° of 44'.
Described punching adopts multiple row dislocation discharging method, utilizes space between two circle of contacts, arranges another row tangent circle.
Described punching stamping-out arrangement scope is 25 row.
The invention has the beneficial effects as follows, adopt multiple row dislocation punching technique, rely on aborning automation feeding technology to make the minimizing of billot width, workpiece charging step pitch, workpiece technique scrap (bridge) surplus, can improve stock utilization approximately 1-1.5%; Adopt dislocation technology, make full use of effective area, saved billot width, improved effective piece rate approximately 711%; Mould adopts the independent stamping-out technology of multiple row, optimizes the arrangement of and combines the width of reducing the loss, improves blank comprehensive utilization ratio, can make billot rolled twig rate improve approximately 24%; Utilize each mutual space of circle simultaneously, when producing rotor punching, also produced byproduct, improved the comprehensive utilization of material, account for approximately 4-11% of overall utilization; The quality of production that has improved the operating efficiency of production process and improved product, has extended service life of mould, has reduced production cost and has improved production safety guarantee.
Accompanying drawing explanation
Fig. 1 is the multiple row of the present invention grading blanking die schematic diagram that misplaces.
The specific embodiment
Below, by Figure of description, further set forth the present invention;
As shown in Figure 1, a kind of conical rotor motor multiple row dislocation punching blanking process.Described processing step is: coiled strip unreels smoothing feeding → high velocity ram machine → multiple row misplace grading blanking die → rotor punching 1(and byproduct) output, same motor model punching 1 cylindrical is identical with axis hole utilizes space between two circle of contacts, arrange another row tangent circle, stator core inner circle and rotor outer circle be taper shape, cone angle scope is 9 ° of 15'--28 ° of 44', and the scope of stamping-out is arranged can be between 25 row.
In process of production, by means of NcRF-700 feeding levelling machine feeding → by P2H-300 high velocity ram machine → the deliver to multiple row grading blanking die stamping-out that misplaces, obtain satisfactory major product and time product.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention.All any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
