Abstract
A kind of roll neck combined steel, roll neck punching block is up-small and down-big bell-mouth structure of air, is provided with diameter of bore D2 in the small end of roll neck punching block, is provided with dead head punching block above small end; Dead head punching block is up-small and down-big frustum cone structure, and the height dimension of round platform is H, and dead head punching block center arranges same tapering and equidirectional taper hole, and the bottom of the large end of dead head punching block is provided with diameter of bore D1; Diameter of bore D2 is greater than diameter of bore D1.The utility model structure is simple, versatility is good, combinationally used by dead head punching block and roll neck punching block, solve because the large end of roll neck is measure-alike, just many, the independent making each specification roll neck punching blocks of specification of small end and the problem that causes production cost high, reduce production cost, save human resources, applied and there is good economic and social benefit.
Description
Technical field
The utility model belongs to metallurgical technology field, particularly a kind of roll neck combined steel.
Background technology
At present, at home and abroad in metallurgical industrial furnace, entering stove and coming out of the stove of stock generally all adopts roller-way to take on steel, steel is bad to be sent in stove by the dress steel rider road in stove, tap roller-way by bad for steel by step rate in the stove that discharge end is delivered in charging end stepping, complete the heating process that steel is bad simultaneously, then sent industrial furnace by roller-way of tapping in stove and be rolled.Furnace roller is in the market made up of the body of roll, roll neck and roll shaft, and described roll shaft is arranged on roll neck, and roll neck is welded on the two ends of the described body of roll.
In actual production, because the large end of roll neck is measure-alike, just the dimensions of small end is many, if made by the size of maximum specification, can shine into the waste of producing material, improve production cost, waste human resources; If make separately the roll neck punching block of all size, production cost is high, and versatility is low.
Summary of the invention
The purpose of this utility model to solve the problems of the technologies described above.
The purpose of this utility model is achieved in that a kind of roll neck combined steel, comprise roll neck punching block, it is characterized in that: described roll neck punching block is up-small and down-big bell-mouth structure of air, is provided with diameter of bore D2 in the small end of roll neck punching block, is provided with dead head punching block above small end.
Described dead head punching block is up-small and down-big frustum cone structure, and the height dimension of round platform is H, and dead head punching block center arranges same tapering and equidirectional taper hole, and the bottom of the large end of dead head punching block is provided with diameter of bore D1.
Described diameter of bore D2 is greater than diameter of bore D1.
The utility model structure is simple, versatility is good, combinationally used by dead head punching block and roll neck punching block, solve because the large end of roll neck is measure-alike, just many, the independent making each specification roll neck punching blocks of specification of small end and the problem that causes production cost high, reduce production cost, save human resources, applied and there is good economic and social benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. dead head punching block; 2. roll neck punching block; 101. height dimension H; 102. diameter of bore D1; 201. diameter of bore D2.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to restriction of the present utility model:
A kind of roll neck combined steel, comprise roll neck punching block 2, described roll neck punching block 2 is up-small and down-big bell-mouth structure of air, is provided with diameter of bore D2201, is provided with dead head punching block 1 above small end in the small end of roll neck punching block 2; Described dead head punching block 1 is up-small and down-big frustum cone structure, and the height dimension of round platform is H, and dead head punching block 1 center arranges same tapering and equidirectional taper hole, and the bottom that dead head punching block 1 is held greatly is provided with diameter of bore D1102; Described diameter of bore D2201 is greater than diameter of bore D1102.
During concrete enforcement, 1), roll neck punching block 2 is made; 2), dead head punching block 1, the height dimension H101 of dead head punching block is made, can according to required specification processing more than one piece; 3), roll neck punching block 2 is connected use with the dead head punching block 1 of required specification.
Obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of amplifying out or variation be still among protection domain of the present utility model.
