Description
Technical field:
The utility model relates to processing unit (plant), relates in particular to the processing unit (plant) of rotary body hollow parts.
Background technology:
The rotary body hollow parts is to machine through spinning machine under normal conditions, and spinning is a kind of special moulding process, and it is to borrow the roller be contained on the spinning machine and the relative motion between the core, forces blank to take place to shift and be shaped by the core profile.This method belongs to semi-hand operation, and (t≤2mm) can not an operation accomplishes repeatedly moulding and will increase the intermediate annealing operation and eliminate flow harden being out of shape excessive part, only is used for small lot batch manufacture to be suitable for thin-wall part.Spinning is a kind of special moulding process, and it is that blank is fixed on the spinning machine, when blank rotates with lathe, through specific purpose tool blank is shaped gradually.
Processing spinning body hollow parts, the instrument that must have spinning machine and match with it, its characteristics; Labour intensity is big, is easy to wrinkling part greatly for distortion and needs repeatedly spinning, consequent work hardening; So need to increase intermediate annealing, this method is suitable for trial-production and small lot batch manufacture.A large amount of rotary body hollow parts are arranged in the high-voltage switch gear electrical circuitry equipment, and for example high-voltage switch gear (close switch) is gone up the various fingertips that shape differs, and just belongs to this part.Demand is big, and is of many uses.
Utility model content: the purpose of utility model: can produce the rotary body hollow parts in enormous quantities in order to provide a kind of, the product efficiency of production is high, and quality is good, the processing unit (plant) of the measured rotary body hollow parts of matter.
In order to reach as above purpose; The utility model is taked following technical scheme: comprise die assembly and pressure-applying unit, die assembly comprises core, clamping rotary body hollow parts in the middle of last core and the punch; Rotary body hollow parts lower inner is following core, outsidely is a tube; The tapering plate that has the inner inclination face that pressure-applying unit comprises upper padding plate and is attached thereto.
The further technical scheme of the utility model is: also comprise lower bolster, said die assembly is positioned at lower bolster, through pin and lower bolster location.
The further technical scheme of the utility model is: the said core of going up is divided into two, and two interblocks connect through hexagon socket head cap screw.
Adopt as above the utility model of technical scheme, have following beneficial effect:
Base, car goes out part blank as requested, with behind the rough annealing, puts into frock again, puts convex module in order, uniformity.Put tapering plate and backing plate successively; Forcing press is slowly given punch a power vertically downward through backing plate and the special delivery of tapering plate downwards; Conversion through angle changes axial force vertically downward into radial load again, makes punch to the center extrusion sections, makes its moulding.The advantage of this processing method is:
1) wall thickness of part can reach 4mm;
2) can produce in batches;
3) efficient is high, and quality is good, and labour intensity is low.
Description of drawings:
In order to further specify the utility model, further describe below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of utility model;
Fig. 2 is the structural representation of the part of utility model processing;
Wherein: 1. upper padding plate; 2. tapering plate; 3. hexagon socket head cap screw; 4. go up core; 5. punch; 6. prop up tube; 7. descend core; 8. pin; 9. lower bolster; 10. rotary body hollow parts; 11. pressing plate.
The specific embodiment:
Embodiment to the utility model describes below in conjunction with accompanying drawing, and embodiment does not constitute the restriction to the utility model:
In conjunction with Fig. 1 and Fig. 2;
In order to reach as above purpose; The utility model is taked following technical scheme: comprise die assembly and pressure-applying unit, die assembly comprises core 4, last core 4 and punch 5 middle clamping rotary body hollow parts 10; Rotary body hollow parts 10 lower inner are following core 7, outsidely are a tube 6; The tapering plate 2 that has the inner inclination face that pressure-applying unit comprises upper padding plate 1 and is attached thereto.
The further technical scheme of the utility model is: also comprise lower bolster 9, said die assembly is positioned at lower bolster 9, through pin 8 with lower bolster 9 location.
The further technical scheme of the utility model is: the said core 4 of going up is divided into two, and two interblocks connect through hexagon socket head cap screw 3.Its objective is to taking out the rotary body hollow parts smoothly.
Can also place pressing plate on the said upper padding plate 1.
Deflection with eliminate wrinkling parameters relationship
Extruding also wrinkling or impression can occur as spinning in the process.Find through test of many times, deflection and impression with wrinkling be directly proportional and deflection big more, impression with wrinkling also just big more.For addressing this problem, we increase the extruding number of times to the big part of deflection.Generally get D/d=1.5-2 k=2, D/d=2-2.5 gets K=3-4.(K-pushes number of times for diameter before the D-distortion, d-distortion back diameter).
2. softening the processing: part need be annealed.Annealing temperature is controlled at about 700 °, and color is dark red can rapid entry.
3. other relevant parameter: the design of frock, all and part contact surface roughness 3.2.Punch-die hardness should be controlled at HRC30-38.
4. finishing is handled: the part after the extruding is cut edge on lathe and polishing, and effect can be followed.
Utilize the method and this frock, simple to operate, steady quality, efficient is high, and labour intensity is low, and is less demanding to workman's technical ability.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
