Description
Technical field
The present invention relates to rotary swaging machine, particularly to a kind of swaging apparatus of rotary swaging machine.
Background technology
Swaging technology (referred to as swaging) is a kind of for the metal works precise plastic such as pipe fitting, bar, steel wire rope one-tenth
The processing technology of shape.Its general principle is: forging hammer is evenly distributed the periphery in workpiece to be machined, and forging hammer is rotating around workpiece
Radially do high frequency, the reciprocating motion of little stroke simultaneously, repeatedly workpiece is forged, workpiece is accumulated as relatively by small deformation
Large deformation, thus realize the deformation effect of workpiece.This increment shapes progressive forming relatively, and the uniformity of material deformation is more preferable,
Material is little with the frictional force of forging hammer.
As an important branch of Metal Forming technique, technique of swaging has lot of advantages: (1) processing range
Wide it is adaptable to various metals material；(2) waste material is few, does not substantially produce the chip of machining, material-saving；(3) subsequent technique
Few, surface accuracy is high, and the workpiece size tolerance of shaping of swaging, the precision of Form and position error are higher, machining that need not be extra；
(4) production efficiency is high, and the process-cycle of an operation of generally swaging is only between 12s ~ 30s；(5) good product performance, swages into
The workpiece material continuous tissue of shape, consistency are high, and surface forms work hardening layer, and the intensity of workpiece is high.
Rotary swaging forming equipment is swaged in forming process in workpiece, and the little stroke of radial direction high frequency of forging hammer back and forth forges motion, main
If by with forging hammer centrifugal force when rotated and outer ring around the uniform roller of main shaft circumferencial direction of swaging collision effect Lai real
Existing.And the curved surface of forging hammer is typically the curved surface of parabola rule or cosine acceleration law, forging hammer in current rotary swaging forming equipment
It is single-contact between curved surface and roller, therefore in the rotary swaging forming equipment course of work, forging hammer is with roller-contact brief acceleration even
Continuous property is poor, big to the impact of roller, causes the vibration of the whole machine of equipment and noise big, and, impact little to the impact acceleration of workpiece
Time is longer, and impact strength is little, and efficiency is low, and forming accuracy is poor.In addition, also there is tup quick abrasion, need to often adjust forging hammer pad
The thickness of piece, service life is short to cause efficiency low, machining accuracy differ to phenomenon.These defects lead to swaging techniques to be only suitable for
In processing a little findings, the processing of the part larger to volume has difficulties, and leads to swaging techniques range of application to be restricted.
Content of the invention
There is drawbacks described above in the swaging apparatus for solving existing rotary swaging machine, the present invention provide a kind of rational in infrastructure, plus
Work speed is faster, impact strength is little, noise is low, efficiency high, the high magnetic force of forming accuracy is contactless swaging apparatus.
For achieving the above object, the scheme that the present invention takes is: a kind of magnetic force of rotary swaging machine is contactless swaging apparatus,
Including rotation forging disk, and some are distributed in rotation forging disk and can make radial direction linear reciprocating motion in rotation forging disk
Magnetic forging hammer；It is characterized in that: the tup of one end outwardly of aforementioned magnetic forging hammer is provided with polarity towards consistent strong magnets a；
Rotation forging disk outer periphery is evenly equipped with quantity and magnetic forging hammer quantity identical strong magnets b, the polarity of strong magnets b and strength
The polarity of magnet a is set to heteropole relatively.
Further illustrating as such scheme, during work, under the centrifugal action in rotation forging disc spins, magnetic is forged
Hammer moves out, with rotation forging disk go to strong magnets b relatively when, strong magnets a in magnetic forging hammer are subject to strong magnets b together
After the repulsion of polar repulsion, magnetic forging hammer is promoted reversely to move to workpiece direction, magnetic forging hammer forges to workpiece simultaneously.From
And the magnetic force of realizing magnetic forging hammer is contactless forges, efficiently avoid the shock of forging hammer and similar roller when forging, equipment shakes
Dynamic little, greatly reduce noise, improve working environment, it is to avoid the abrasion of forging hammer tup, substantially increase the use of forging hammer
Life-span.Meanwhile, substantially do not need to adjust the thickness of forging hammer pad, the power effect of high-intensity magnetic field is big, to the impact acceleration of workpiece more
Greatly, the attack time is shorter, and impact strength is big, efficiency high, and forming accuracy is greatly improved, good product consistency, can process relatively
Larger-size workpiece.
As the improvement of such scheme, it is magnetic forging hammer quantity twice that aforementioned rotation forging disk outer periphery is evenly equipped with quantity
Strong magnets b, with respect to the polarity of strong magnets a, the opposite polarity ground interval setting of adjacent strong magnets b.In above-mentioned side
On the basis of case, increased same polarity strong magnets b, under the centrifugal action in rotation forging disc spins, magnetic forging hammer is outside
Motion, with rotation forging disk go to strong magnets b relatively when, strong magnets a in magnetic forging hammer are by strong magnets b heteropolarity phase
After the gravitation inhaled, magnetic Speed of Forging Hammer faster, increases magnetic forging hammer stroke so that magnetic forging hammer is reversely transported within the unit interval
When dynamic, the acceleration time is longer, to workpiece to forge dynamics bigger, improve process velocity, be typically 4 to work pieces process speed ~
12s.
It is provided with safety clearance 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.
It is provided with resilient snubber outside aforementioned strong magnets a or strong magnets b.Preferably, aforementioned flexible bolster is rubber
Cushion rubber.
Operation principle: repelled each other the principle that there is a natural attraction between the sexes using the magnet same sex, in conjunction with the design of magnetic forging hammer tup, make tup
Strong magnets a of top of supply line and strong magnets b are maintained at certain reasonable clearance, in rotation forging disc spins, constantly in rotation
Turn strong magnets b outside forging disk and form the alternately attracting active force repelling each other, make tup produce the linear reciprocating motion of radial direction, shape
The impulsive force of workpiece in pairs.Due to maintaining certain reasonable clearance, tup and strong magnets b between tup and strong magnets b
Do not produce and directly touch friction, it is to avoid abrasion, reduce noise, so that the tup life-span is extended, the machining accuracy of workpiece is had
Effect ensures.
From the foregoing, it will be observed that the present invention mainly has the advantage that compact conformation；Using the magnet same sex repel each other that there is a natural attraction between the sexes former
Reason, is reached tup and is no directly touched with strong magnets b outside rotation forging disk, efficiently solve traditional forging hammer tup top one and class
The abrasion producing like roller touching and noise problem, make the service life of tup be greatly prolonged, the high precision of processing workpiece,
Uniformity is good, can be with the relatively large workpiece of processing dimension；The thickness without frequent adjust pad can be used for a long time, effect
Rate greatly improves！To rotary swaging machine, larger range of application, actively promotes effect.
