Abstract
The invention discloses a kind of split type combination edger roll, including roll shaft and the roller set being set on roll shaft, roller set lower surface is provided with the retaining ring that split is covered with roller, and the retaining ring is installed on roller and covers on lower surface by draw-in groove location structure.The present invention processes the end face slot part of its waterproof action with roller set main part individual cast, and be assembled together, assembling uses elastic conjunction, and structure uses draw-in groove location structure, and fastening is reliable, equally meet use requirement, casting amount can be reduced, net-gross ratio is reduced, the alloy dosage of body of roll outer layer is saved, processing capacity is reduced, so as to reduce manufacturing cost.
Description
Technical field
The invention belongs to roll technology field, and in particular to a kind of split type combination edger roll.
Background technology
Hot strip mill edger roll is more special relative to other type vertical roll of rolling structures.As shown in figure 1, the roller of such edger roll
Body lower surface have one it is long with a diameter of φ 855x70mm of body of roll outside diameter drop 312mm, diameter of bore be φ 735x90mm
It is deep to play sealing, the end face groove of waterproof action.Edger roll structure is routinely combined, this part of the protrusions of φ 855/735 will be used as roller set
A part, not only lengthen whole roller set blank, hair is only than big, and inside and outside redundance also wants car to fall, long processing time,
Cause to be more expensive to manufacture.
The content of the invention
The technical problem to be solved in the invention is to provide one kind.
In order to solve the above technical problems, the technical solution adopted in the present invention is：
A kind of split type combination edger roll, including roll shaft and the roller set being set on roll shaft, roller set lower surface is provided with and roller set point
The retaining ring of body, the retaining ring is installed on roller and covers on lower surface by draw-in groove location structure.
Further, the draw-in groove detent mechanism includes the circular groove being arranged on roller set lower surface, and the circle is recessed
The circular draw-in groove bigger than circular groove diameter, the circular groove, circular draw-in groove are additionally provided with groove on the side of bottom surface
Center line and roller set center line overlap.
Further, the retaining ring is interference fit with circular groove, circular draw-in groove.
By adopting the above-described technical solution, the technological progress that the present invention is obtained is：End by its waterproof action of the invention
Face slot part and roller set main part individual cast processing, and be assembled together, assembling uses elastic conjunction, and structure uses draw-in groove
Location structure, fastening is reliable, equally meets use requirement, can reduce casting amount, reduces net-gross ratio, saves the alloy of body of roll outer layer
Consumption, reduces processing capacity, so as to reduce manufacturing cost.
Brief description of the drawings
Fig. 1 is existing edger roll structural representation；
Fig. 2 is retaining ring of the present invention and roller casing connecting structure figure；
Fig. 3 is the part A enlarged drawing of Fig. 2 of the present invention.
Specific embodiment
The present invention is described in further details with reference to embodiment：
The present invention is that a kind of Split hot hoop mill combines edger roll, including roll shaft and the roller set being set on roll shaft, such as Fig. 2 institutes
Show, roller covers 1 lower surface and is provided with the retaining ring that split is covered with roller, and the retaining ring is installed under roller set by draw-in groove location structure
On end face.
The draw-in groove detent mechanism includes the circular groove being arranged on roller set lower surface, the bottom of near in the circular groove
Be additionally provided with the circular draw-in groove bigger than circular groove diameter on the side in face, the circular groove, the center line of circular draw-in groove with
Roller set center line overlaps, referring to Fig. 2 and Fig. 3.
The retaining ring is interference fit with circular groove, circular draw-in groove.
During present invention assembling, roll shaft and home roll are first covered into assembling, then retaining ring is placed in home roll set hole, retaining ring
Upper surface is fitted with home roll set, blocks retaining ring after home roll set cooling.
