Description
Technical field
The utility model is related to technical field of forging, more particularly to a kind of for forging the special of large-scale flanged electric machine main shaft
Use jaw device.
Background technology
Flanged electric machine main shaft is one of vital part of large-scale fire-proof motor equipment, and its weight is generally 2t ~ 8t or so.
At present, most of shaping of the flanged electric machine main shaft uses flat-die forging, and its basic forging process is：Steel ingot（Or blank）Upsetting
--the non-flange portion of pulling-imprint-forging each step-is forged recessed all directions-impressing for slightly-pulling-jumping-up-pulling
Shelves-finishing.During " the non-flange portion of pulling " and downstream process, flange position is used as " pincers handle ", it is considered to flange position
The factors such as yielding and pincers handle the steady effect of folder are influenceed by follow-up pulling, effective thickness δ >=250mm of flange just can guarantee that blank
Clamp not unstability.However, the flange thickness of general flanged electric machine main shaft is much smaller than 250mm, during in particular by blank forging,
It is firm in order to ensure to clamp in forging process workpiece, flange thickness need to be increased to δ >=250mm, so cause forging crop
Weight increase；Simultaneously as flange diameter is general than larger, with the increase of flange diameter, the crop weight of flange increases therewith
Greatly, up to 1000kg sometimes, so as to cause the significant wastage of raw material.Therefore, material cost, optimization frock knot how to be reduced
Structure, is always the problem that the whole society faces.
Utility model content
The purpose of this utility model is that providing a kind of motor flange axle forges special jaw, asks to solve above-mentioned technology
Topic.
The utility model uses following technical scheme to achieve the above object：
A kind of flanged electric machine main shaft forges special jaw, including jaw, operation machine jig arm, operation machine caliper, bearing pin, tight
Gu nut, flanged electric machine main shaft, jaw are assemblied in operation machine jig arm by bearing pin and clamp nut；Operation machine jig arm is same
It is assemblied in by bearing pin and clamp nut in operation machine caliper, the jaw face width and jaw face length are normal
Angle and jaw working face cambered surface radius are selected not all in accordance with the flange specification of flanged electric machine main shaft between number, jaw working face
Same size, the escape arc radius and groove length are constant, and are met>=200, the groove cambered surface
Radius meets R3-R1 more than or equal to the flange radius of flanged electric machine main shaft and the difference of axle journal radius.
It is preferred that, the jaw be divided into above and below two pieces, and two pieces of jaws by bearing pin and nut be assemblied in operation machine press from both sides
In arm.
Compared with prior art, the utility model has advantages below：The utility model is simple in construction, easy to operate, if
Meter is reasonable；The two ends of flanged electric machine main shaft can be easily clamped, the crop weight of flange end is greatly reduced, saves original
Material, it is safe and reliable, preferably promote the use of.

Embodiment
The utility model is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model is when clamping the small diameter shaft position of flanged electric machine main shaft, by jaw 1
Working face is clamped directly at the small diameter shaft position of flanged electric machine main shaft, and contact surface effective length is L1-L2, and is designed>=200, it ensure that it presss from both sides steady effect.
As shown in Fig. 2 jaw face width W and jaw face length L1 are angle [alpha] between constant, jaw working face
And jaw working face arc radius R1, different sizes are selected according to the flange specification of flanged electric machine main shaft, the escape
Arc radius R2 and groove length L2 is constant, and meets >=200, the groove cambered surface radius R3, and meets R3-R1 and be more than
Equal to the flange radius and the difference of axle journal radius of flanged electric machine main shaft.
As shown in figure 3, two pieces of jaws 1, are formed from hot die steel 5CrNiMo forgings；Jaw 1 is by bearing pin 4a and tightly
Gu nut 5a is assemblied in jig arm 2；Jig arm 2 is assemblied in the caliper 3 of operation machine again by bearing pin 4b and clamp nut 5b.Adopt
With the connected mode of bearing pin and clamp nut, it is easily installed and uses.
As shown in figure 4, the utility model is when clamping the flange position of flanged electric machine main shaft, by the interior work of jaw 1
Face is clamped at the flange end-journal of flanged electric machine main shaft；Flange is placed in the groove of the inner working face of jaw 1.Ordinary circumstance
Under, the neck length of flanged electric machine main shaft is far longer than the overall length of the inner working face of jaw 1, using axle journal as stress surface, substitution
When former flange position is as stress surface, its flange thickness need to be thickeied to δ >=250mm, to ensure that its presss from both sides steady effect.
Described above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality
With new teaching, in the case where not departing from principle of the present utility model and spirit, the change that is carried out to embodiment, repair
Change, replace and modification is still fallen within protection domain of the present utility model.
