In metallurgical, Field of Heat-treatment, it is often necessary to metal material or part be conveyed under high temperature environment, generally
Use live-roller.Existing live-roller includes the body of roll, roll neck, spindle nose, and roll neck is welded on spindle nose, and body of roll both ends are welded on two
On roll neck.Some producers are improved this to be disclosed for V shape rollers, such as Chinese utility model patent CN201520147408.1
A kind of V types roller set, structure is to include outer diameter, end face, boss, and V type grooves, V type grooves bottom are provided at outer diameter center
Arc surface is provided with, V type grooves bottom is provided with reinforcing rib；V types roller covers to be set between both sides of the face and reinforcing rib and V type grooves
There is circular platform type cavity；Reinforcing rib has been horizontally disposed with through-hole.The structure using when with roll shaft be assembled to form furnace roller, using process
In, not easily to fall off, cracking, service life is long, once welding seam failure cracks, will not make whole branch furnace roller that can not use, weld again
It can be continuing with after connecing.But still remain the problem of being easily damaged under high temperature environment.
Invention content
The purpose of this utility model is that in view of the deficiencies of the prior art, and it is stainless to provide a kind of high temperature resistant convenient for heat dissipation
Steel
Live-roller, scientific structure, bearing capacity is stronger, suitable for hot environment.
Technical solution is used by the utility model solves its technical problem：A kind of high temperature resistant stainless steel convenient for heat dissipation
Live-roller, including the body of roll, the both ends of the body of roll are respectively welded roller head, and the roller head and the body of roll are internally provided with the sky of perforation
Chamber, the body of roll, roller head are coaxial rotary body, and the axis of the body of roll is rotary shaft, the outer diameter and internal diameter of the body of roll from
Centre becomes larger to both ends, and the outer surface of the body of roll is arc surface, and the outer diameter and internal diameter of the roller head are along far from the roller
The direction of body tapers into, the diameter of the cavity with the body of roll, roller head diameter change and change.

Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, is not this practicality
Novel practical range limited to this.
It is shown as shown in Figure 1, Figure 2, the high temperature resistant stainless steel live-roller convenient for heat dissipation of the present embodiment, including the body of roll 1, institute
The both ends for stating the body of roll 1 are respectively welded roller head 2, and the roller head 2 and the body of roll 1 are internally provided with the cavity 3 of perforation, institute
State the body of roll 1, roller head 2 is coaxial rotary body, the axis of the body of roll 1 is rotary shaft, the outer diameter of the body of roll 1 and interior
Diameter becomes larger from the middle to both ends, and the outer surface of the body of roll 1 is arc surface, the outer diameter of the roller head 2 and internal diameter edge
Tapered into far from the direction of the body of roll 1, the diameter of the cavity 3 with the body of roll 1, roller head 2 diameter change
And change.The utility model structure, is cast by stainless steel, the arc surface of the one side body of roll 1 be convenient for by the workpiece conveyed to
Centre is drawn close, and avoids deviating, and on the other hand, can be increased heat dissipation area with the volume of enlarged cavity 3, be conducive to pass through sky
Chamber 3 enhances cross-ventilation, good heat dissipation effect.
Further, the outer end of the roller head 2 is provided with bearing block 4, so as to be connect with bearing.
Further, the bearing block 4 is provided with the ventilation hole for being connected to the cavity 3, using the ventilation hole into
Row heat dissipation.
Further, the junction wall thickness of the roller head 2 and the body of roll 1 thickeies.
Finally it should be noted that above example is only to illustrate the technical solution of the utility model rather than to this reality
With the limitation of novel protected range, although being explained in detail with reference to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be modified or replaced equivalently to the technical solution of the utility model, without departing from this
The spirit and scope of utility model technical solution.
