Description
Technical field
The utility model is related to a kind of combination edger roll location structure, specifically a kind of positioning for combining vertical rolls set and roll shaft
Structure, belongs to metallurgical equipment part field.
Background technology
Combination edger roll is by roller set and roll shaft split production, the roll being finally assembled together.Roller set in use is work
Make part, as loss occurs in the extension of use time, roller set is unloaded to after scrapping and installs after new roller covers and can continue
Use, combination edger roll reduces use cost.Make combination edger roll key be by roller set and roll shaft be assembled together, it is necessary to
There is reliable location structure.For the ease of assembling in traditional location structure, positioning table is arranged on to the end of roll shaft, roll shaft end
The phenomenon of stress concentration occurs in the positioning table in portion, influences roll hardness, cause the accident hidden danger.
Utility model content
The purpose of this utility model is to provide that a kind of accurate positioning is reliable, the high combination edger roll of combination edger roll intensity after positioning
Location structure.
To achieve these goals, the technical solution adopted in the utility model is：
A kind of location structure for combining vertical rolls set and roll shaft, combination edger roll includes roller and covered and roll shaft, the location structure
The annular boss of annular recess and the cylindrical middle part of roll shaft in the middle part of roller set endoporus is constituted, the width and annular boss of annular recess
Width it is identical, the diameter of annular recess is more than the diameter of annular boss.
Further, the outside diameter positioned at the roll shaft of annular boss both sides is of different sizes；Positioned at annular recess both sides
The internal diameter of roller set is of different sizes.
Further, the outside diameter of the roll shaft on the upside of annular boss is less than 6~8mm of diameter of annular boss, position
The outside diameter of roll shaft on the downside of annular boss is less than the diameter 1mm of annular boss；What the roller on the upside of annular recess covered
Diameter of bore is less than 6~8mm of diameter of annular recess, and the diameter of bore of the roller set on the downside of annular recess is less than annular recess
Diameter 1mm.
Further, the outer round surface of the roll shaft of annular boss both sides is provided with the roll shaft groove of annular, roll shaft groove
Two equal roundings in angle of bottom land.
Further, diameter big 1~2mm of the diameter of annular recess than annular boss.
By adopting the above-described technical solution, the technique effect that the utility model is obtained has：
It is small that such a location structure is suitable for barrel diameter, and roll neck diameter is larger, fit diameter close to and roll shaft main shaft
The situation of diameter.Relative to end location structure, because the annular boss of positioning is located at the middle part at assembling position, it is to avoid roller
The stress concentration of shaft end positioning table influences for roll hardness, improves the anti-accident ability of roll.
Location structure implementation process in the utility model is simple, and reality is combined by groove platform location structure and interference fit
Now accurately and reliably position, long using the combination edger roll service life of the detent mechanism, anti-accident ability is strong.

Embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described in further details to the utility model：
Embodiment 1
The utility model discloses a kind of location structure for combining vertical rolls set and roll shaft, combination edger roll generally comprises roller set
2 and roll shaft 1.Roller set 2 equivalent to traditional roll working portion, typically from high hardness alloy.In combination edger roll, by roller set
2 location structures for being fixed on the centre position of roll shaft 1 are more stablized, it is possible to increase the bulk strength of combination edger roll.This practicality is new
Roller reliablely and stablely can be covered 2 centre positions for being fixed on roll shaft 1 by the location structure that type is provided.
The annular boss 3 of annular recess 4 and roll shaft 1 cylindrical middle part of the location structure in the middle part of roller 2 endoporus of set is constituted,
The width of annular recess 4 is identical with the width of annular boss 3, and the diameter of annular recess 4 is more than the diameter of annular boss 3, typically
It is set to diameter big 1~2mm of the diameter than annular boss 3 of annular recess 4.Concrete structure is as shown in Figure 1 and Figure 2.B ends in Fig. 1
Upper end is represented, C-terminal represents lower end, the state of the combination edger roll shown in Fig. 1 is state when using.It is combination edger roll dress in Fig. 3
The state of timing.Using interference fit between roll shaft 1 and roller set 2.
Outside diameter positioned at the roll shaft 1 of the both sides of annular boss 3 is of different sizes；Roller positioned at the both sides of annular recess 4 covers 2
Internal diameter is of different sizes.It is preferably arranged to following form：Outside diameter positioned at the roll shaft 1 of the upside of annular boss 3 is less than ring-type
6~8mm of diameter of boss 3, the diameter 1mm of annular boss 3 is less than positioned at the outside diameter of the roll shaft 1 of the downside of annular boss 3；Position
It is less than 6~8mm of diameter of annular recess 4 in the diameter of bore of the roller set 2 of the upside of annular recess 4, positioned at the downside of annular recess 4
The diameter of bore of roller set 2 is less than the diameter 1mm of annular recess 4.The upper side of annular boss 3 plays main positioning action, prevents roller from covering 2
Glide；Time positioning action is played in the lower surface of annular boss 3, prevents roller covers from being altered on 2.The setting can ensure that positioning stablity is reliable
In the case of, the location structure is more prone to when hot charging is realized.
The roll shaft groove 5 of annular, the bottom land of roll shaft groove 5 are provided with the outer round surface of the roll shaft 1 of the both sides of annular boss 3
Two equal roundings in angle.The effect of roll shaft groove 5 is to reduce annular boss 3 and the stress concentration of the junction of roll shaft 1, improves ring
The intensity of shape boss 3, and then extend the service life of the assembly roller using the detent mechanism.
It is small that such a location structure is suitable for barrel diameter, and roll neck diameter is larger, fit diameter close to and roll shaft main shaft
The situation of diameter.Relative to traditional location structure positioned at roll shaft end, because the annular boss of positioning is located at department of assembly
The middle part of position, it is to avoid the stress concentration of roll shaft end positioning table influences for roll hardness, improves the anti-accident of combination edger roll
Ability.
Location structure implementation process in the utility model is simple, and reality is combined by groove platform location structure and interference fit
Now the roll shaft of combination edger roll and roller set are accurately and reliably positioned, anti-thing long using the combination edger roll service life of the detent mechanism
Therefore ability is strong.
The method that combination edger roll with the location structure in the utility model is matched somebody with somebody using hot charging is implemented, and detailed process is such as
Under：
1st, roller is covered into 2 lower surfaces first before assembling（I.e. roller covers the larger one end of diameter of bore）It is heated to being adapted to temperature upward
Afterwards, it is placed on melt pit；
2nd, by the lower end of roll shaft 1（That is larger one end of roll shaft outside diameter）, the C-terminal in Fig. 4 is sling upward, in roller set 2
Hole is aligned, and slow decentralization loads roller and covers 2 endoporus, until the annular recess 4 that roller covers 2 aligns with the annular boss 3 of roll shaft 1；
3rd, cooling back roller set 2 is fitted together closely with roll shaft 1, and concrete structure is as shown in Figure 4.
