Description
Technical field
The present invention relates to steekle mill apparatus fields, and in particular to a kind of bottom working roll system that pre-straightening machine sky crosses mode replaces
Changing device.
Background technique
In the production of steekle mill, due to rolled piece non-uniform temperature, extend the reasons such as deviation, cooling and conveying, it can not
Cause to roll that wave type occurs in rear steel plate or wooden dipper is bent with avoiding.Meet product standard regulation in order to ensure finished steel plate is straight, is rolled up in furnace
Design installation pre-straightening machine after milling train.
When steel plate passes through straightener, especially steel plate has discount, hits, friction, can make to straightener bottom working roll system
At the damage of bottom working roll system, the precision of straightener work is influenced, and causes equipment consumption aggravation, increases spare parts cost, increases
Add manual maintenance amount, for this purpose, straightener empty can be crossed and be run, when steel plate does not need aligning to protect bottom working roll system, this hair
The bright device for devising a kind of quick replacement bottom working roll system.
Summary of the invention
To overcome the deficiency, the object of the present invention is to provide it is a kind of quickly, efficiently, small investment, easily operated realization
Pre-straightening machine sky crosses mode bottom working roll system alternative.
The technical solution adopted by the present invention to solve the technical problems is: a kind of pre-straightening machine sky crosses the bottom working roll of mode
It is alternative, including bottom working roll system, lifting hydraulic cylinder, replacement roller bed device, backing plate, the side of the bottom working roll system is set
There is transmission shaft, the other side of the bottom working roll system is equipped with guide rail, replacement roller bed device is equipped on guide rail, replaces roller bed device
One end far from bottom working roll system is equipped with alternative and lifts hydraulic cylinder, and two sides are equipped with lifting liquid below the bottom working roll system
The side of cylinder pressure, the backing plate is equipped with backing plate push-and-pull hydraulic cylinder.
Further, one or two replacement roller-way, absolute altitude and bottom working roll road system are installed on the replacement roller bed device
In bottom working roll road it is concordant, replacement roller-way be free roll.
The invention has the following advantages: structure is simple, it can be rapidly performed by switching when straightener work comes into operation,
Meet production requirement；It can be effectively prevented from steel plate damage caused by the shock and friction of straightener bottom working roll system, improved
Service life of equipment reduces spare parts consumption.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is control platform schematic diagram of the invention.
Fig. 3 is hydraulic principle figure of the invention.
In figure, 1 bottom working roll system, 2 lifting hydraulic cylinders, 3 backing plates, 4 backing plate push-and-pull hydraulic cylinders, 5 replacement roller bed devices, 6 are replaced
Changing device lifts hydraulic cylinder, 7 guide rails, 8 transmission shafts.
Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.
Cross the bottom working roll system alternative of mode according to Fig. 1, Fig. 2, a kind of pre-straightening machine sky shown in Fig. 3, including under
Working roll system 1, lifting hydraulic cylinder 2, replacement roller bed device 5, backing plate 3, the side of the bottom working roll system 1 are equipped with transmission shaft 8, institute
The other side for stating bottom working roll system 1 is equipped with guide rail 7, replacement roller bed device 5 is equipped on guide rail 7, replacement roller bed device 5 is far under
One end of working roll system 4 is equipped with alternative and lifts hydraulic cylinder 6, and it is hydraulic to be equipped with lifting for two sides below the bottom working roll system 1
The side of cylinder 2, the backing plate 3 is equipped with backing plate push-and-pull hydraulic cylinder 4.
Further, one or two replacement roller-way, absolute altitude and bottom working roll road system are installed on the replacement roller bed device 5
In bottom working roll road it is concordant, replacement roller-way is free roll, plays the role of conveying, i.e., when steel plate passes through without motor driven
So that steel plate is had discount, leveller equipment will not be caused to damage.
The working principle of pre-straightening machine bottom working roll system alternative are as follows:
1, when straightener comes into operation, the lifting hydraulic cylinder 2 for being placed in 1 two sides of bottom working roll system is risen, the lower work of the push-in of backing plate 3
Under roller system, lifting hydraulic cylinder is fallen, and bottom working roll system falls on backing plate, guarantees rigidity when straightener work；
2, when straightener sky is out-of-date, bottom working roll system is lifted hydraulic cylinder and rises, and backing plate pulls out, and lifting hydraulic cylinder is fallen, under
Working roll system will be less than work roll table absolute altitude certain altitude, the replacement roller bed device positioned at fore side under the promotion of hydraulic cylinder,
Enter working region in the guide rail that bottom working roll is fastened along design, replaces and one or two roller-ways are installed on roller bed device, mark
High concordant with work roll table, roller-way is free roll, plays the role of conveying when steel plate passes through without motor driven, even if steel plate
There is discount, leveller equipment will not be caused to damage；
3, when need to come into operation again straightener when, will replacement roller bed device pull out, when needing replacing roller box, will replace
It changes roller bed device to hang away, the replacement of roller box is unaffected.
The present invention is not limited to the embodiment, anyone should learn that the structure made under the inspiration of the present invention becomes
Change, the technical schemes that are same or similar to the present invention are fallen within the scope of protection of the present invention.
Technology not described in detail in the present invention, shape, construction portion are well-known technique.
