It connects on platform sling II 26, platform sling II 26 is welded on cover board 24, and 24 both ends of cover board are bolted on pedestal 22.
It is provided with circular hole in pressure plate II 23, is also equipped with circular hole on platform sling II 26, by bolt, nut by pressure plate II
23 are fastened on platform sling II 26.The different pressure plate II 23 of length can be made for the bar of different-diameter, so that pressure plate
II 23 lower end surfaces have different upper-lower heights.Alternatively, the circular hole in pressure plate II 23 or platform sling II 26 is replaced with into waist round hole,
So that the upper and lower position of pressure plate II 23 is adjustable, to adapt to the bar of different-diameter.Certainly, for the stick of different-diameter
The different pressure plate II 23 of material production length is more optimal solution, because being at this moment circle on pressure plate II 23 and platform sling II 26
Hole will not be such that the upper and lower position of pressure plate II 23 changes (if by pressure plate II 23 even if bar hits pressure plate II 23
Circular hole replaces with waist round hole, since bar strike can be such that pressure plate II 23 moves up).
Certainly, in other technical solutions, pressure plate II 23 can also fix (i.e. inseparable) be arranged above sliding block 21.
This is suitable for only processing a kind of bar of diameter specifications.
The effect of pressure plate II 23 is similar with the effect of pressure plate I 12.Pressure plate II 23 is for further limiting bar
Get rid of material phenomenon.Pressure plate II 23 protrudes into groove II 25 limit effect improved to bar.And the lower end of pressure plate II 23
The minimum range of face and bar upper surface is 3 ~ 5mm, and there are such gaps, so that bar is easily accessible in groove II 25 and energy
It is enough smoothly to move ahead.
Minimum range a and b between pressure plate II 23 and third inclined-plane 251, the 4th inclined-plane 252 are respectively less than the outer of bar
Diameter, prevent bar is from deviating from space defined by II 23 lower end surface of pressure plate, third inclined-plane 251 and the 4th inclined-plane 252, tool
Play the role of getting rid of material when preferably limiting bar rolling rotation.
II 23 lower end of pressure plate meets to supplied materials direction side and is also provided with chamfering (this example is not set), preferably to lead
Enter bar.
Third inclined-plane 251 and the 4th inclined-plane 252 are plane, and the angle between third inclined-plane 251 and the 4th inclined-plane 252
β can preferably be worth less than 90 ° and be taken at 55 ° ~ 65 °, be 60 ° in this example.It can make that groove II 25 is relatively deep, relatively narrower in this way, it can be compared with
Bar is limited well gets rid of material in rolling.
In other technical solutions, third inclined-plane 251 and the 4th inclined-plane 252 are not limited to be plane, can also be arcwall face,
It can make to can be point contact between third inclined-plane 251 or the 4th inclined-plane 252 and bar rather than line contacts, it in this way can be further
The damping of third inclined-plane 251 and the 4th inclined-plane 252 to bar is reduced, transports bar more swimmingly.
In this example, the structure of roller 11 is transformed, the feeding roller wheel between heating coil mechanism 31 is substituted for
Sliding block 21(is referring to Figures 1 and 2), in other technical solutions, can only by the feeding roller between heating coil mechanism 31 in turn
It changes sliding block 21 into, and roller 11 is still continued to use into Fig. 1 and feeding roller 1 shown in Fig. 2.
In this example, since the feeding roller wheel between heating coil mechanism 31 has been substituted for sliding block 21, sliding block 21 is compared and is sent
Expect roller have lesser volume, the clearance distance between adjacent heating coil mechanism 31 can be further decreased, can reduce to
Within 150mm, the clearance distance in this example between adjacent heating coil mechanism 31 is 130mm.On the one hand core assembly 20 is determined to stick
Material is played a supporting role, and prevents longer bar from bending；On the other hand determine the pedestal 22 and sliding block 21 in core assembly 20
It can be made to shorter (on bar conveying direction) (comparison diagram 1), therefore can reduce between adjacent heating coil mechanism 31
Clearance distance.Reduce the clearance distance between adjacent heating coil mechanism 31 can reduce bar heating coil mechanism 31 it
Between thermal loss when moving.This example determines core assembly 20 and can be decreased to the clearance distance between adjacent heating coil mechanism 31
Within 150mm, within even 130mm, thermal loss can be reduced and improve the heating efficiency of heating coil mechanism 31.
The feeding centering device for ball rolling mill production line of this example, working principle is substantially are as follows:
Feeding roll assembly 10 will be placed on groove I 15(Fig. 4 by the roller 11 of rotation) in bar by heating coil machine
Structure 31(Fig. 3) enter in ball rolling mill (not shown) after heating, the first inclined-plane 151 of groove I 15 and the second inclined-plane 152 simultaneously with
Bar contacts and increases conveying frictional force and can limit bar by clamping action and get rid of material phenomenon when rotating rolling, and
Material phenomenon is got rid of by what pressure plate I 12 can further limit bar；It is set between heating coil mechanism 31 and determines core assembly 20
(Fig. 3) carries out support to bar by sliding block 21(Fig. 7) and groove II 25 and gets rid of material in conjunction with the limitation bar of pressure plate II 23
Phenomenon.
