Description

Cold-strip mill draw the material press-roller device

Technical field

The utility model relates to that drawing of a kind of milling train use on material press-roller device, the especially cold-strip mill draws the material press-roller device.

Background technology

How fast, stably milling train is the high speed cold-strip mill especially, in the crossing process of beginning before rolling, finish to draw and expect and whole to wear band work extremely important.Be related to the service efficiency of milling train on the one hand, fast, stably finish and draw the material crossing process, can save service working time, improve milling train efficient greatly; The automaticity that is related to milling train is on the other hand finished automatically by PLC control and to be drawn the material crossing process, can alleviate operative employee's labour intensity, improves the security performance of milling train.What be equipped with on the milling train at present draws the material tape threading apparatus, mostly is installed in the uncoiling district, rather than is arranged in the rectification roll place near milling train, and result of use is undesirable, still will manually participate in when time before the band arrival machine, does not reach quick, stable purpose.That generally uses simultaneously draws the material tape threading apparatus, and complex structure, volume be big and heavy, take up room.Therefore provide that a kind of milling train especially uses on the high speed cold-strip mill efficiently to draw the material press-roller device very necessary.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned weak point, thus a kind of cold-strip mill is provided draw the material press-roller device, design ingenious, rational in infrastructure, easy to use and reliable, have stability and rapidity, can significantly improve the performance of milling train.

According to the technical scheme that the utility model provides, the material press-roller device employing of drawing of cold-strip mill is installed on the bearing of the left and right sides by rolling bearing and bearing cap at the rectification roll two ends; Citation roller is installed in first swing arm, and first swing arm is fixed on the balance staff, and oil motor is installed in a side shaft end of citation roller, and oil motor can drive citation roller and rotate; Pressure roller is installed in second swing arm, and second swing arm is fixed on the balance staff; The balance staff two ends are fixed on the bearing of the left and right sides by axle sleeve and gland, and oscillating oil cylinder links to each other with a side shaft end of balance staff; Swing guide one end is installed on the bearing cap of rectification roll, and the elevating movement of swing guide is by hydraulic oil cylinder driving.

Be mutually 145 degree angles between described first swing arm and second swing arm.

Described rectification roll, citation roller and pressure roller roller surfaces carry out surface hardening respectively to be handled.

Described axle sleeve is wear-resisting copper sheathing or does not have cunning dynamic bearing oscillating oil cylinder and can do 180 degree swings, suitable, each 90 degree of counter clockwise direction.

The beneficial effects of the utility model are: the integrated design of three rollers, structure are ingenious rationally; Hydraulic-driven, response speed are fast; Easy to use and reliable, automaticity is high; It is stable, quick to wear band; Be particularly suitable for the use of high speed cold-strip mill, can significantly improve the performance of milling train.

Description of drawings

Fig. 1 is that the utility model draws the elevation of expecting press-roller device.

Fig. 2 is that the utility model draws the vertical view of expecting press-roller device.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

As Fig. 1～shown in Figure 2, comprise left and right sides bearing 1, rectification roll 2, bearing cap 3, citation roller 4, first swing arm 5, gland 6, oscillating oil cylinder 7, axle sleeve 8, second swing arm 9, pressure roller 10, swing guide 11, band 12, oil cylinder 13, oil motor 14 and balance staff 15 etc.

The utility model comprises left and right sides bearing, rectification roll mechanism, citation roller mechanism, pressing roll mechanism, swing mechanism, swing guide.

Described rectification roll mechanism is made of rectification roll 2, bearing cap 3 etc., and rectification roll 2 two ends are installed on the left and right sides bearing 1 by rolling bearing and bearing cap 3, and rectification roll 2 roller surfaces are made surperficial Quenching Treatment.

Described citation roller mechanism is made of citation roller 4, first swing arm 5, oil motor 14 etc., citation roller 4 is installed in first swing arm 5, first swing arm 5 is fixed on the balance staff 15, and oil motor 14 is installed in a side shaft end of citation roller 4, and oil motor 14 can drive citation roller 4 and rotate.Citation roller 4 roller surfaces are made surperficial Quenching Treatment.

Described pressing roll mechanism is made of pressure roller 10, second swing arm 9 etc., and pressure roller 10 is installed in second swing arm 9, and second swing arm 9 is fixed on the balance staff 15.Pressure roller 10 roller surfaces are made surperficial Quenching Treatment.

Described swing mechanism is made of balance staff 15, axle sleeve 8, gland 6, oscillating oil cylinder 7 etc., and balance staff 15 two ends are fixed on the left and right sides bearing 1 by axle sleeve 8 and gland 6, and oscillating oil cylinder 7 links to each other with a side shaft end of balance staff 15.Axle sleeve 8 adopts wear-resisting copper sheathing to make, and oscillating oil cylinder 7 can be done 180 degree swings, suitable, each 90 degree of counter clockwise direction.
