Description
Technical field
The invention belongs to short stress path rolling mill fields, embedded more particularly, to step in short stress path rolling mill roller system
Double sealing structure.
Background technique
As shown in Figure 1 and Figure 2, short stress path rolling mill topping roll assembly 10 and bottom roll assembly 11 need during the rolling process
Water-spraying control roll, iron scale etc. is possibly into wearing zero be mounted in step 1 in step 1 in the operation of rolling
Part makes milling train break down, therefore dustband 12 is installed between step 1 and housing screw 2, prevents iron scale etc. from entering
Step 1.But it because dustband 12 is relatively thin, damages it easily during the installation process, increases production cost, on-line rolling uses
In the process, sealing effect is poor, if there is oxide skin to enter between dustband 12 and housing screw 2, increased wear degree, and dustband
12 lose sealing effect, and oxide skin enters step 1 at this time, can make milling train failure that can not be produced, influence to produce
Efficiency；In addition, housing screw 2 can vibrate lower end when milling train works, this vibration also will increase oxide skin etc. and pass through spiral shell
Line gap enters the probability of step 1, therefore improves the structure still ten of step 1 in the assembly of short stress path rolling mill roller system
Divide necessity.
Summary of the invention
In view of this, the present invention is directed to propose the embedded double sealing structure of step in short stress path rolling mill roller system,
To realize effective sealing between housing screw and step, prevent oxide skin etc. from entering step.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:
The embedded double sealing structure of step in short stress path rolling mill roller system, lower bearing cover for seat is on housing screw；
The housing screw is equipped with J-type sealing ring；The step is close in J-type sealing ring lower end, and upper end is equipped with pressing plate；Institute
It states pressing plate to cover on the housing screw, the pressing plate is fixed on the step by screw and washer.
Further, the J-type sealing ring is the exoskeletal rubber oil sea of J-type.
Further, the pressing plate is ring-type.
Further, it is had the gap between the pressing plate inner hole and housing screw outer diameter.
Further, the step and the housing screw junction are provided with annular stepped boss；The annular step
Terraced boss and the step are integrally formed.
Further, the ladder quantity of the annular stepped boss is 2, is divided into the first annular boss and the second ring-type is convex
Platform；First annular boss is located above second annular boss；First annular boss, the second annular boss and institute
State step integrated molding.
Further, the first annular boss excircle diameter is equal to the excircle diameter of second annular boss；
The first annular boss inner periphery diameter is greater than the inner periphery diameter of second annular boss；Second annular boss
Inner periphery diameter is greater than the outer diameter of the housing screw.
Further, the second annular boss inner periphery is close to the J-type sealing ring；The second annular boss height
Lower than the J-type sealing ring height；The pressing plate is located in the first annular boss inner periphery, and logical with the second annular boss
Screw is crossed to connect with collar thread；The screw upper end is located in the first annular boss inner periphery.
Compared with the existing technology, the embedded dual-seal knot of step in short stress path rolling mill roller of the present invention system
Structure has the advantage that
The embedded double sealing structure of step in short stress path rolling mill roller of the present invention system, due to using
The sealing structure of step and the setting of housing screw contact position pressing plate and J-type sealing ring, in milling train work, because J-type seals
Circle top has pressing plate to keep off the oxide skin that can obstruct the overwhelming majority, while the spring carried by adjusting J-type sealing ring,
J-type sealing ring can be made to reach optimal seal effect, and be hardly damaged when the installation of J-type sealing ring, service life is longer, sealing effect
Also better than original dustband effect, therefore production cost can be reduced, accident rate is reduced, production efficiency is improved.In addition, J-type sealing ring
Also have dustproof effect concurrently.
