Abstract
The utility model discloses a reversible four-roller fully hydraulic rolling machine. The fully hydraulic rolling machine comprises a bottom seat, a casing-shaped frame is arranged on the bottom seat; the casing-shaped frame is internally provided with an upper bearing roller and a lower bearing roller; an upper work roller and a lower work roller are arranged between the upper and the lower bearing rollers; two ends of the roller shafts of the upper and the lower bearing rollers and the upper and the lower work rollers are provided with bearing seats; the bearing seats are vertically and matched with two side arms of the casing-shaped frame in a sliding way; one end of the roller shaft of the upper bearing roller is connected with a motor and a reducer. the top part of the casing-shape frame is provided with a pressing-down hydraulic cylinder; the upper end of the pressing-down hydraulic cylinder is fixed at the top part of the casing-shaped frame; the lower end of the pressing-down hydraulic cylinder is pushed and contacted with the bearing seats at two ends of the upper bearing roller. By using the fully hydraulic rolling machine, the thickness of the rolled plates has small error and high precision; not only the thicker plates can be rolled, but also the thinner plates can be also rolled; the applicable range is not restricted. The utility model is suitable for rolling all metal plates.
Description
(1) technical field
The utility model relates to a kind of cold rolling machinery.Be four-high reversing cold mill specifically, be applicable to rolling to various sheet metals.
(2) background technology
At present, used screwdown gear mostly is turbine, scroll-type screwdown gear on the reversing four-high mill.This screwdown gear is made of parts such as screw mandrel, nut, turbine and scroll bars.Drive screw mandrel by motor by scroll bar, turbine and nut during work the downward roof pressure of top backing up roll is realized gap adjustment between roller and the roller, so that satisfy rolling needs various different-thickness sheet materials.Though adopt this screwdown gear can realize gap adjustment between roller and roller, because between turbine and scroll bar, between nut and screw mandrel fit clearance is arranged all, the gap between roller and roller is difficult to harmonize, and makes that the sheet metal thickness error that rolls out is bigger.Therefore, adopt the milling train of this screwdown gear, can only the above thickness of rolling 0.2mm than heavy-gauge sheeting, can not the following thickness of rolling 0.2mm than light sheet, the scope of application is restricted.
(3) summary of the invention
The purpose of this utility model is to provide a kind of all-hydraulic milling train.This all-hydraulic milling train, rolling sheet metal thickness error is little, precision is high, can be rolling than heavy-gauge sheeting, also can be rolling than light sheet, the scope of application is unrestricted.
For achieving the above object, the utility model is taked following technical solution:
All-hydraulic milling train of the present utility model, contain base, the shaped as frame frame is arranged on the base, upper and lower backing roll is arranged in the shaped as frame frame, upper and lower working roll is arranged between upper and lower backing roll, all there is bearing block at the roll shaft two ends of backing roll and upper working rolls and lower working rolls up and down, are vertically between this bearing block and shaped as frame frame two side arms to be slidingly matched; Roll shaft one termination of top backing up roll has motor and reductor.Be characterized in that the shaped as frame frame top has hydraulic cylinder for reduction system, the upper end of this hydraulic cylinder for reduction system is fixed on the shaped as frame frame top, and the bearing block at lower end and top backing up roll two ends offsets.
Adopt such scheme, have the following advantages:
Because all-hydraulic milling train of the present utility model is provided with hydraulic cylinder for reduction system at its frame top, the upper end of this hydraulic cylinder for reduction system is fixed on the shaped as frame frame top, the bearing block at lower end and top backing up roll two ends offsets, change traditional turbine, the scroll-type screwdown gear is the fluid pressure type screwdown gear, has eliminated mechanical fit clearance, the gap between roller and the roller of being convenient to harmonize, rolling sheet metal thickness error reduces, precision improves thereby make, no matter thick, light sheet all can be rolling, and the scope of application is unrestricted.Through on probation, the sheet material of the following thickness of the all-hydraulic milling train rolling 0.03mm of energy of the present utility model.
(4) description of drawings
Accompanying drawing is an all-hydraulic rolling mill structure schematic diagram of the present utility model.
(5) specific embodiment
As shown in drawings, all-hydraulic milling train of the present utility model contains base 10, and shaped as frame frame 9 is installed on the base 10.This shaped as frame frame is a cuboid, and it is erects the shape layout, is disposed with top backing up roll 5, top working roll 6, bottom working roll 7 and lower support roller 8 according to top-down order in it.All there is bearing block 3 at said top backing up roll 5, top working roll 6, bottom working roll 7 and lower support roller 8 two ends, and the both sides of these bearing blocks all are processed with guide rail.Two side arms along shaped as frame frame 9 vertically is processed with chute accordingly, the guide rail of top backing up roll 5, top working roll 6, bottom working roll 7 and lower support roller 8 two end axles bearings 3 both sides is in respectively in this chute, is slidingly matched so that make between bearing block 3 and shaped as frame frame 9 two side arms vertically being.Shaped as frame frame 9 tops are provided with two hydraulic cylinder for reduction system 4, and this two hydraulic cylinder for reduction system is corresponding with the bearing block 3 at top backing up roll 5 two ends respectively, and its upper end is fixed on the shaped as frame frame 9, and the bearing block 3 of lower end and top backing up roll 5 respective end offsets.
Roll shaft one end at top backing up roll 5 is provided with motor and reductor 2, the roll shaft one end Joint of the output shaft of this motor and reductor and top backing up roll 5, and it is installed on the base 10 by support 1.
