Abstract
The utility model relates to a laterally pressing device for the roller of a four-roller plate belt rolling machine. The utility model uses the mechanical force to press (pull) the bearing seat of the rollers towards a vertical column on one side of a window, a gap between the bearing seat on the side and the vertical column is eliminated, and the rollers can be in the stable state; accordingly, a cross angle between the center lines of the rollers, and the axial force subjected by the rollers can be reduced. The pressing (pulling) force can be omitted when the rollers are replaced.
Description
The utility model is four roller strip-mill strip roll side direction hold down gags.
The center line of four-high mill working roll generally all departs from the backing roll center line in vertical direction, to cause the horizontal force of fixed-direction, attempt makes working roll abut in the inboard of frame, but in fact because the wearing and tearing of bearing block sideskid and framework pillar liner plate, the added influence that also has transmission system, roller system can not reach stable state like this, especially when reversible rolling, serviceability and product quality to milling train all has adverse influence like this, moreover because of the uneven wear of slide plate and liner plate, the roll center line is actual to intersect mutually, make roll for the helical movement, thereby the formation axial force, general axial force reaches (1～3) % of roll-force, can reach (5～10) % when the angle of the crossing is big.Excessive axial force causes the destruction of thrust bearing of the roll or axial locking device, has a strong impact on milling train production.
For addressing the above problem, the utility model proposes a kind of roll side direction hold down gag, its purpose is to utilize mechanical force to press (drawing) to press to window one side and column roll chock, eliminates crack between this side shaft holder slide plate and the column liner plate, makes roll be in stable state.
The utility model concrete structure can be:
1. utilize the original roll axial locking device of milling train to be transformed into the device that has the side direction pressuring action concurrently, the shape or the length that can change the axial locking plate achieve the goal.Figure (1) is the situation of side hydraulic locking plate lengthening, the bottom of the locking slot (6) of bearing block (1) is directed reach in its end of axial locking plate (2 ') behind the lengthening, the hydraulic thrust of mobile latch (2 ') is passed on the bearing block (1), bearing block (1) is pressed to window one side and this heel post (4) presses, crack (δ) concentrates on opposite side between bearing block (1) and the column.Figure (2) is the situation that changes a side latch shape, (end of 2 ") is a stairstepping to the axial locking plate; end plane (S) contacts with roll chock (1) on rolling direction; hydraulic thrust can be passed to bearing block (1) equally; if there is not hydraulic locking apparatus; also can add dedicated side hydraulic fluid cylinder pressure (12) in milling train the same side, bearing block (11) is pressed to a side of framework pillar, shown in the visible figure (3).
2. no matter above which kind of situation, hydraulic thrust should be adjustable, its control system (not shown) comprises that hydraulic power source and control valve can control the size of hydraulic cylinder input pressure and the direction of motion of cylinder plunger, make it when rolling, can produce needed pressure the bearing block side direction compressed, but when roll change pressure relief.
3. do not having on the medium and small-scale rolling mill of hydraulic power source, can adopt the structure of figure (4), roll chock (22) links to each other with the spring that an end is fixed in framework pillar with pull bar (24) by adjusting nut (25), bearing block (22) is pulled to the column of window one side by spring force, make gap (δ) concentrate on opposite side, the length that the pulling force of spring (26) can change pull bar (24) by the bidirectional helical of adjusting nut (25) changes, and spring force can be removed during roll change.
Claims (2)
1, a kind of roll side direction hold down gag, the bottom of the locking slot (6) of bearing block (1) is directed reach in the end of the axial locking plate (2 ') after it is characterized in that extending, or roll mandrel (the stairstepping end plane (S) of 2 ") contacts with roll chock (1) or spring (26) one ends link to each other with bearing block (22) with pull bar (24) by adjusting nut (25); the other end is fixed on the framework pillar (21) to latch
2, by the said roll side direction of claim 1 hold down gag, its feature also is: spring tension changes by the length of the bidirectional helical change pull bar (24) of adjusting nut (25).
