Description
Technical field
The utility model relates to rotary swaging machine, particularly a kind of swaging apparatus of rotary swaging machine.
Background technology
Swaging technology (abbreviation is swaged) is a kind of processing technology for metal works precision plastic formings such as pipe fitting, bar, steel wire ropes.Its general principle is: forging hammer is circumferentially distributed on the periphery of workpiece to be machined, and forging hammer radially does the reciprocating motion of high frequency, little stroke while rotating around workpiece, repeatedly forges workpiece
,workpiece is accumulated as moderate finite deformation by small deformation, thus realizes the deformation effect of workpiece.This increment is shaped relative progressive forming, and the uniformity of material deformation is better, and the frictional force of material and forging hammer is little.
As an important branch of Metal Forming technique, technique of swaging has lot of advantages: (1) processing range is wide, is applicable to various metals material; (2) waste material is few, does not substantially produce the chip of machining, saves material; (3) subsequent technique is few, and surface accuracy is high, and the workpiece size tolerance of shaping of swaging, the precision of Form and position error are higher, without the need to extra machining; (4) production efficiency is high, and the process-cycle of an operation of usually swaging is only between 12S ~ 30S; (5) good product performance, workpiece material continuous tissue, the density of shaping of swaging are high, and surface forms work hardening layer, and the intensity of workpiece is high.
Rotary swaging forming equipment is swaged in forming process at workpiece, and the little stroke of radial high frequency of forging hammer back and forth forges motion, mainly by being used for realizing around the collision of the uniform roller of main shaft circumferencial direction of swaging with forging hammer centrifugal force when rotated and outer ring.And the current curved surface of the curved surface of forging hammer normally parabola rule or cosine acceleration law in rotary swaging forming equipment, single-contact between forging hammer curved surface and roller, therefore in the rotary swaging forming equipment course of work, forging hammer and roller-contact brief acceleration poor continuity, large to the impact of roller, cause the vibration & noise of equipment complete machine large, and little to the impact acceleration of workpiece, attack time is longer, impact strength is little, and efficiency is low, and forming accuracy is poor.In addition, also there is tup quick abrasion, need the thickness of often adjustment forging hammer pad, service life, the short efficiency that causes was low, machining accuracy differ to phenomenon.These defects cause swaging techniques to be only applicable to process a little finding, have difficulties, cause swaging techniques range of application to be restricted to the processing of the larger part of volume.
Utility model content
For the swaging apparatus solving existing rotary swaging machine exists above-mentioned defect, the utility model provide a kind of rational in infrastructure, process velocity is faster, impact strength is little, noise is low, efficiency is high, the magnetic force that forming accuracy is high is contactless swaging apparatus.
For achieving the above object, the scheme that the utility model is taked is: a kind of contactless swaging apparatus of magnetic force of rotary swaging machine, comprise and rotate forging dish, and somely to rotate in forging dish being distributed in and can rotating the magnetic forging hammer making radial linear reciprocating motion in forging dish; It is characterized in that: the tup of one end outwardly of described magnetic forging hammer is provided with polarity towards consistent strong magnets A; Rotate forging dish outer periphery and be evenly equipped with the quantity one group strong magnets B identical with magnetic forging hammer quantity, it is relative that polarity and the polarity of strong magnets A of this group strong magnets B are set to heteropole.
Further illustrating as such scheme, during work, under centrifugal action when rotating forging disc spins, magnetic forging hammer outwards moves, with rotation forging dish forward to strong magnets B relative time, after strong magnets A in magnetic forging hammer is subject to the repulsion that strong magnets B same polarity repels each other, promote magnetic forging hammer oppositely to the motion of workpiece direction, magnetic forging hammer forges workpiece simultaneously.Thus the magnetic force realizing magnetic forging hammer is contactless forges, efficiently avoid the shock of forging hammer and similar roller when forging, vibration equipment is little, greatly reduce noise, improve working environment, avoid the wearing and tearing of forging hammer tup, substantially increase the service life of forging hammer.Meanwhile, substantially do not need the thickness adjusting forging hammer pad, the power effect of high-intensity magnetic field is large, larger to the impact acceleration of workpiece, attack time is shorter, and impact strength is large, and efficiency is high, forming accuracy significantly improves, good product consistency, can process the workpiece that relative size is larger.
As the improvement of such scheme, aforementioned rotation forging dish outer periphery is also evenly equipped with another group quantity strong magnets B identical with magnetic forging hammer quantity, and it is relative that polarity and the polarity of strong magnets A of this group strong magnets B are set to homopolarity.On the basis of such scheme, add same polarity strong magnets B, under centrifugal action when rotating forging disc spins, magnetic forging hammer outwards moves, with rotation forging dish forward to strong magnets B relative time, after strong magnets A in magnetic forging hammer is subject to the attracting gravitation of strong magnets B heteropolarity, magnetic Speed of Forging Hammer is faster, magnetic forging hammer stroke is increased within the unit interval, when making the counter motion of magnetic forging hammer, the acceleration time is longer, to workpiece to forge dynamics larger, improving process velocity, is generally 4 ~ 12S to work pieces process speed.
Safety clearance is provided with between aforementioned strong magnets A and strong magnets B.
Preferably, aforementioned magnetic forging hammer quantity is more than 2.Further preferably, aforementioned magnetic forging hammer quantity is 6.
Resilient snubber is provided with outside aforementioned strong magnets A or strong magnets B.Preferably, aforementioned flexible bolster is rubber ring.
Operation principle: utilize the magnet two like magnetic poles repel each other principle that there is a natural attraction between the sexes, in conjunction with the design of magnetic forging hammer tup, the strong magnets A at position, tup top and strong magnets B is made to remain on certain reasonable clearance, when rotating forging disc spins, constantly rotating the formation of the strong magnets B outside the forging dish attracting active force repelled each other alternately, make tup produce radial linear reciprocating motion, form the impulsive force to workpiece.Owing to maintaining certain reasonable clearance between tup and strong magnets B, tup and strong magnets B do not produce directly to touch and rub, and avoid wearing and tearing, reduce noise, the tup life-span is extended, and the machining accuracy of workpiece is effectively ensured.
As from the foregoing, the utility model mainly contains following advantage: compact conformation; Utilize the magnet two like magnetic poles repel each other principle that there is a natural attraction between the sexes, reach tup with the strong magnets B rotated outside forging dish without direct touching, efficiently solve traditional forging hammer tup top one and touch with similar roller the wearing and tearing and noise problem that produce, the service life of tup is extended greatly, the precision of processing work is high, uniformity is good, can the relatively large workpiece of processing dimension; Can use for a long time and not need often to adjust the thickness of pad, efficiency improves greatly! The application wider to rotary swaging machine, actively promotes effect.
