Embodiment
With reference to Fig. 1 to Figure 11, technical scheme is described further, but is not limited to this explanation.
Embodiment 1：
A kind of preparation method of the direct-current motor shell of flange shaping, including casing is divided into corresponding fuselage 1 and end cap 2
Two parts, and fuselage 1 and end cap 2 are made respectively, then will both welding fabrications.
End cap 2 is produced using punch forming process, and its production stage includes：
A. steel plate cutting：Steel plate is cut into square, size is 1.25 times of the diameter of fuselage 1；Such size
The structure of casing suitable for more.
B. punch forming：Each press depth about 8mm, punching press 3 times.But according to the difference of product depth, stamping material
Difference, the difference of shape of product, stretching depth and drawing numbers can be different.
C. trimming：After steel plate punched is molded, unnecessary material is cut off.
Punch forming process is completed using punch press, and punch forming speed is fast, and one-time formed depth is limited, it is necessary to more times
To reach production requirement, the requirement to material is of a relatively high for punching press.
The fuselage 1 is made by seamless steel pipe using flanging process, and the flanging process includes：
A. steel pipe segment -- steel pipe is cut into isometric several sections, every section of length needs to determine according to the length of fuselage 1.
B. breach is rushed -- two corresponding breach are stamped out in one end of steel pipe, reserved breach is advantageous to flange, made
It is molded more regular.
C. flange -- the steel pipe of made breach is put into cavity plate 3 fixed, leaving certain gaps uncovered by the economic plan is directed in the drift 4 of cone
One end, corresponding punching press make steel pipe turn up to form base, and for drift 4 during pushing, steel pipe edge touches drift 4 first
Arc section, as drift 4 continues traveling downwardly, steel pipe is slided along the arc section of drift 4 and deformed, and is stopped until drift 4 contacts with cavity plate 3
Only, the angle of base and raw steel body is close to 90 °, surface folding, out-of-flatness.
D. flatten -- by the base of out-of-flatness by flattening,
E. trimming -- base is cut into predetermined shape.
Fuselage 1 is formed using seamless steel pipe cutting.Seamless steel pipe has the characteristics of precision is high, and inner surface is smooth, but compares
Welded still pipe price is higher, is mainly used in the occasion higher to motor requirement.
The welding manner of fuselage 1 and end cap 2 is：Using welding wire as auxiliary material, the gap between filling fuselage 1 and end cap 2,
Fuselage 1 and end cap 2 are fixed, and the plumb joint of welding machine is rotated by manipulator, and melting welding wire is welded, such welding side
Formula accuracy is high, and speed of welding is fast, and the requirement to equipment is high, and cost is of a relatively high.
Embodiment 2：
A kind of preparation method of the direct-current motor shell of flange shaping, including casing is divided into corresponding fuselage 1 and end cap 2
Two parts, and fuselage 1 and end cap 2 are made respectively, then will both welding fabrications.

A. steel plate cutting：Steel plate is cut into square, size is 1.25 times of the diameter of fuselage 1；
B. drawing and forming：Each stretching depth about 8mm, is stretched 3 times；
C. trimming：After formed by stretching steel plate, unnecessary material is cut off.
Stretch forming process is completed using hydraulic press, and drawing and forming speed is slow, low to material requirements, and form depth is big, into
Type number is few, but the overall production cycle is longer.
Fuselage 1 is made by steel pipe using flanging process, and the flanging process includes：
A. steel pipe segment -- steel pipe is cut into isometric several sections,
B. breach is rushed -- two corresponding breach are stamped out in one end of steel pipe,
C. flange -- the steel pipe of made breach is put into cavity plate 3 fixed, drift 4 is directed at one end of leaving certain gaps uncovered by the economic plan, corresponding
Punching press makes steel pipe turn up to form base,
D. flatten -- by base by flattening,
E. trimming -- base is cut into predetermined shape.
Fuselage 1 is formed using welded still pipe cutting.Welded still pipe precision is relatively low, and inner surface has a soldered, meeting
Certain influence is produced on processing precision of products, but because its is cheap, is mainly used in the less demanding occasion of motor.
The welding manner of fuselage 1 and end cap 2 is：The plumb joint transfixion of welding machine, use a servomotor band motivation
Body 1 and the stationary fixture synchronous rotary of end cap 2, using argon arc welding, directly by high temperature caused by welding by end cap 2 and fuselage 1
Metal melt combines connection, completes the lap welding of periphery one and connects.Such welding manner, the requirement to equipment is relatively low, and cost is low.
In the making of end cap 2, drawing and forming has the advantages that precision is high, appearance looks elegant, but punch forming is relatively drawn into
Type has the advantages of production efficiency is high, and cost of labor is cheap.
The part of fuselage 1 uses seamless steel pipe or welded still pipe, the technique for eliminating the shaping of stretcher casing multiple tracks, processing technology
Simply, it is easy to process, the cycle is short, and can be required according to client is different to casing length, cut different length size steel pipe at any time, make
It is more convenient to obtain casing production, reduces the input of different casing dies, shortens casing fabrication cycle, reduce casing cost.
This flange shaping casing has both the cheap price for rolling casing, has both the waterproof effect of integrally stretching casing again,
And the precision of its own is higher, it is ensured that the uniformity being installed on motor, improves the efficiency of motor and reduces making an uproar for motor
Sound.
