Description
Technical field
The invention belongs to field shaping technique, and relate to a kind of electric driver for forcing press.In addition originally
Invention further relates to a kind of forcing press with this driving means.
Background technology
The servo-pressing machine of directly driving is learnt by background technology.This forcing press needs the highest turning during molding
Square.In order to realize the design optimized, operating point is arranged in the scope of motor peak power.By this arbitrary boundary conditions often
Make forcing press motor size excessive, this is because produced torque peak is only for being required for some working range
, and a kind of motor with the highest rotating speed the least torque constant must be used.
Summary of the invention
It is an object of the invention to, propose a kind of solution, with this under the conditions of smaller construction expenditure, it is provided that include
Pressure and the particularly advantageous combination of power.This purpose is by a kind of electric driver according to the present invention, or passes through a kind of root
Realize according to the forcing press of the present invention.
According to the present invention, driving means has the first motor, this motor preferably directly, the most directly and do not have
Act on the power train of forcing press with having deceleration transmission, wherein, the second motor refers to (the teilbest ü that only part assembles
Ckter) segmentation motor (Segmentmotor).
For the present invention it is not important that, the most also referred to as forcing press motor first design of electrical motor become one
Direct drive unit.First motor can also act on power train alternatively by gear stage.The most important then: with
The second motor being also referred to as down additional motor is the segmentation motor that assembles of part, it as direct drive unit, namely
Say and directly act on power train.
The present invention considers: some molding scope (working range) inner need one raise torque for applying
Forming force.The pressure applied by forcing press causes the molding scope at the change of shape place on workpiece to be after all to be led to lentamente
Cross, hence for being not required to high dynamic jib motion for this scope.Typically refer to for servo-pressing machine
One scope of first about 30 ° of UT (bottom dead centre).
The core concept of the present invention is: existing forcing press motor is retained as driving motor, and uses special
It is assigned in the additional motor of molding scope.Hereinafter the most important characteristics of the two motor is illustrated.
Forcing press motor, sees on the whole, simply also provides for a smaller part for desirable pressure.According to structure
Form, it the most only or predominantly for after forming process, makes tappet accelerate when high loaded process again.At weight
Before newly reaching molding scope, carried out the braking of tappet by forcing press motor, and then slowly through molding scope.Pass through
Tappet is the highest a kind of dynamic motion between molding scope, it is ensured that the high production rate of forcing press.
Meanwhile, the design size of forcing press motor can be less than former common size.Can for forcing press motor
With the winding flexible program that a kind of cost of selection is optimal.
Forcing press motor is no longer necessary to reach high rotating speed.Result is that current needs reduces when identical torque.Applied
Converter (Umrichter) simply also need to less and therefore cost advantages power component.Dynamo-electric further for pressure
For machine, an optimal working range operating point in other words can be designed with.Which improve torque constant.
Additional motor is only intended to apply additional force, for producing required pressure.When forming process starts, namely
Say that it just works after tappet is braked.In other words, simply to this additional motor galvanization during molding, and with
Rear additional motor is then for providing support for forcing press motor.For tappet motion between molding scope, additional electrical
Machine does not provide anything to help according to the difference of version or helps little.
The segmentation motor of attendant applications is not be fully assembled.The most such as a kind of radial segments motor
For, it does not has (360 °) assembling on the whole circumference of its rotor.It is (primary that part assembling had both related to winding coil in other words
Parts), it is directed to the permanent magnet (secondary component) of motor.In other words, additional motor be in a part of scope coiling and
It is provided with magnet.This part range preferably corresponds to molding scope, say, that the scope of such as 30 °.In other words, dress
The size of the part range prepared is matched with the size of working range.Therefore the unwanted, beyond work of segmentation motor is avoided
Make the assembling of scope.
If it is not, but with a kind of motor being fully assembled as additional motor, as this is from background
The known ground of technology is like that, then this motor be necessarily designed to a little go up the maximum (top) speed between molding scope.Now
This is the most necessary.The maximal rate of additional motor is shaping speed.Additional motor thus may be designed in cost equally
Optimize very much.
Self-evidently, additional motor so designs, i.e. primary components and secondary component is consistent is arranged in overlappingly
In working range.For use those make forcing press motor and additional motor realize coefficient control-, regulation-and monitoring
Device, is discussed the most further, because these are conventional for professional.
Utilization the invention provides a kind of press driving device, and wherein, pressure and power are by optimal ways and means
Mutually it is combined.The application of the invention can reduce the quantity of different motors to be provided, this is because always may be used
To use identical forcing press motor.The requirement replacing higher torque can be reached by the higher assembling of additional motor
Arrive.
For the part range of the assembling of segmentation motor, it is necessary to refer to the part range of a kind of closing.The most favourable
E.g.: assemble two or more part range spaced apart from each other.It is particularly advantageous: i.e. two of additional motor are relatively
The segmentation arranged assembles, and in other words, the segmentation assembled mutually deflects 180 ° of layouts on rotor.The most not only keep away
Exempt from imbalance, double torque can have been realized simultaneously.If it is not, and simply assemble a single segmentation, then have
Profit ground equipped with balance weight body, is used for avoiding imbalance on the side, opposite of rotor.
The invention is not limited in the driving means of the forcing press using Servo Drive Technology's.It can also be used for other
The driving means of forcing press.Important is not the quantity of applied motor.Therefore multiple forcing press motor can also be used
Replace a forcing press motor, and/or use multiple additional motor to substitute an additional motor.Present invention is also not necessarily limited to footpath
To segmentation motor, but can also apply other segmentation motor time realize.In addition the present invention also with the electricity applied
The operation principle of machine is unrelated.The most for the present invention, if select a kind of internal rotor to arrange or outer rotor is arranged not
Important.
