The overhang roll for heating furnace of embodiment according to a first aspect of the present invention is described below with reference to Fig. 1-Fig. 5.
As Figure 1-Figure 5, the overhang roll 4 for heating furnace of embodiment according to a first aspect of the present invention, including roller head
100.
Roller head 100 is rotary structure, and the outer peripheral face of roller head 100 has recessed smooth in center 103 towards roller head 100
Concave surface 101, concave surface 101 is formed as arc surface, concave surface 101 is suitable to place the square billet of different size or the round billet of different size.
As Figure 1-Figure 5, when overhang roll 4 is used for the blank conveying heating furnace, because blank can be different size
The round billet 2 of square billet 1 or different size, by being processed into the outer peripheral face of roller head 100 towards the recessed smooth circular arc in Gun Tou center 103
Concave surface 101, now the peripheral dimension at roller head 100 middle part is little and the peripheral dimension at two ends is big, thus the side of either different size
The base 1 or round billet of different size 2 all can stably be placed on the concave surface 101 of roller head 100, without occurring in roller head 100
The situation of upper rolling, all fine to the locating effect of square billet 1 and round billet 2, facilitate the control of heating furnace step pitch, and by overhang roll
Blank on 4 pushes away the damage that timing is not in roller head 100 and blank and jam phenomenon, and thus, circular arc concave surface 101 can be fitted simultaneously
Answer the square billet of different size and the conveying of the round billet of different size, and can guarantee that the square billet 1 of different size and different size
Round billet 2 can smoothly convey, and makes roller head and blank all without damage.So overhang roll 4 is to convey different size simultaneously
Square billet 1 and different size round billet 2 universal overhang roll.
The overhang roll 4 for heating furnace according to embodiments of the present invention, by by the outer peripheral face of the roller head 100 of overhang roll 4
Be processed into towards the recessed smooth circular arc concave surface 101 in Gun Tou center, overhang roll 4 both can convey different size square billet 1 it is also possible to
The round billet 2 of conveying different size, can reduce engineering construction cost, reduce equipment operation maintenance cost, and the work reducing workman is strong
Degree, saving man-hour, when overhang roll 4 is applied to heating furnace, the utilization rate of heating furnace and its corollary equipment can be improved, improve life
Produce benefit.
In one embodiment of the invention, the minimum point 1011 of concave surface 101 is located at the roller-way centrage 102 of roller head 100
On, wherein roller-way centrage 102 was the center 103 of roller head 100 and the straight line vertical with the central axis 104 of roller head 100.As
Shown in Fig. 2-Fig. 4, roller-way centrage 102 and concave surface 101 intersect at the minimum point 1011 of concave surface.Thus, roller-way concave surface 101 is permissible
Square billet 1 or round billet 2 are played with self-align effect so that square billet 1 and round billet 2 remain at roller-way center in course of conveying
103 surface.
In one embodiment of the invention, as shown in figs 2-4, the maximum gauge of the first end 105 of roller head 100 is more than
Diameter at the minimum point 1011 of concave surface.Thus, it is possible to ensure that blank does not roll to the first end 105 of roller head 100 or falls.
Alternatively, as shown in figs 2-4, pass through circle between the end face 1051 of the first end 105 of roller head 100 and concave surface 101
Angle 1052 transition, defines shirt rim at fillet 1052.Thus, when needing for the blank on overhang roll 4 to be pushed into roller-way (overhang roll
During 4 conveying blank, the concave surface 101 of multiple roller heads 100 is spaced the blank transfer passage being formed side by side) (will be placed on recessed outward
Blank on face 101 is released from the first end 105 of roller head 100) when, roller head 100 will not produce to blank and scratch and jam.
Alternatively, on the cross section of roller head 100, the minimum point 1011 of the first end of roller head 100 105 and concave surface 101 it
Between distance be A, wherein, A meet：7mm≤A≤9mm.As shown in figure 5, the peak of first end 105 of roller head 100 and concave surface
In roller head 100, distance radially needs between 7mm～9mm 101 minimum point 1011.
Further, A meets further：A=8.7mm.The now peak of first end 105 of roller head 100 and concave surface 101
Minimum point 1011 be 8.7mm in roller head 100 distance radially.
In one embodiment of the invention, when square billet 1 is placed on concave surface 101, the maximum square billet 1 of overhang roll 4 conveying
The distance between the minimum point 1011 of bottom surface and concave surface 101 be B, wherein, B meets：B≤3mm.As shown in figure 5, overhang roll 4
The distance between the bottom surface of maximum square billet 1 and minimum point 1011 of concave surface 101 of conveying be less than 3mm so that roller head 100 recessed
Face 101 is closer to straight line.Thus, the conveying that the square billet 1 of different size can smooth can be facilitated implementation, make the recessed of roller head 100
Face 101 is not scratched by square billet 1.
Specifically, when overhang roll 4 conveys the square billet of different size, various sizes of square billet is placed on concave surface 101
1, bottom surface and the distance between the minimum point 1011 of concave surface 101 B due to the maximum square billet 1 of specification meet：B≤3mm, thus,
The distance between the bottom surface of the less square billet of specification 1 and the minimum point 1011 of concave surface 101 are not more than 3mm certainly, thus can
To realize the smooth transportation of the square billet 1 of all specifications.
Further, B meets further：B=1.8mm is so that the concave surface 101 of roller head 100 is closer to straight line.Thus, may be used
It is further ensured that the conveying that the square billet 1 of all specifications can smooth, so that the concave surface 101 of roller head 100 is not scratched by square billet 1.
In one embodiment of the invention, the second end 106 of roller head 100 is provided with away from roller head central axis 104
Direction outward extend flange 1061, the distance between the outer peripheral face of flange 1061 and central axis 104 of roller head 100 are more than
The distance between central axis 104 of the minimum point 1011 of concave surface 101 and roller head 100.As shown in Fig. 2 flange 1061 is arranged on
At second end 106 of roller head 100, and the diameter corresponding to the minimum point 1011 with diameter greater than concave surface 101 of flange 1061.By
This, in the course of conveying of blank, can be avoided blank to collide furnace wall 3, or be stuck between furnace wall 3 and roller head 100 and be difficult to push away
Go out.
Alternatively, on the cross section of roller head 100, between the minimum point 1011 of the outer peripheral face of flange 1061 and concave surface 101
Distance be C, wherein, C meet：C=50mm.
