Abstract
The utility model discloses a lubrication structure of a baffle vertical roller of a tandem rolling set. The lubrication structure comprises a roller body, a hinge pin, an oil inlet pipe and two copper bushes, wherein the hinge pin penetrates into a center through hole of the roller body, and the two copper bushes are sleeved into the two ends of the hinge pin respectively and are placed at the two ends of the center through hole of the roller body. The lubrication structure further comprises two sealing rings which are sleeved into the hinge pin and are placed on the end faces of the two copper bushes respectively. The oil inlet pipe penetrates into the hinge pin from the top end of the hinge pin, and the upper portion and the middle portion of the hinge pin are respectively provided with an oil outlet hole which is communicated with the oil inlet pipe. The lubrication structure overcomes the defects of a traditional lubrication structure of the baffle vertical roller, guarantees the sufficient lubrication of the baffle vertical roller, avoids abnormal abrasion, prolongs the service life of the baffle vertical roller and guarantees the normal operation of the tandem rolling set.
Description
Technical field
The utility model relates to the lubrication system of the perpendicular roller of a kind of tandem rolling unit baffle plate.
Background technology
Usually the roller-way before tandem rolling unit tandem rolling district because there is certain deviation at the rolling center of bloom and tandem mill center, arranges the perpendicular roller of baffle plate at roller-way place side plate and helps to correct steel billet trend, the friction of minimizing steel billet and roller-way side plate.But the perpendicular roller load of this baffle plate is big and very easily cause inordinate wear with long-term contact of high temperature billet steel, often take place to cause disabler because of inordinate wear, make the steel billet head impact can't cross steel or the distortion of steel billet head impact, make tandem mill can't sting steel, loss such as cause that steel billet low temperature is scrapped, the operation of rolling are paused.Tracing it to its cause, all to be that the perpendicular roller lubricating condition of this baffle plate is insufficient cause inordinate wear, causes the perpendicular roller copper sheathing distortion of baffle plate.As shown in Figure 1, the perpendicular roller of former baffle plate is by roll body 1, bearing pin 2, two copper sheathings 3 and oil inlet pipe 4 constitute, bearing pin 2 penetrates roll body 1 central through hole, bearing pin 2 two ends are adopted two copper sheathings 3 to fasten and are connected with roll body 1, oil inlet pipe 4 penetrates bearing pin 2 from bearing pin 2 bottoms, the oil outlet 21 that is communicated with oil inlet pipe 4 is offered at bearing pin 2 middle parts, this structure grease very easily spills between the gap of bearing pin and lower end copper sheathing because of the pressure effect, grease is piled up in the inner the latter half of roll body after the oil outlet at bearing pin middle part flows out simultaneously, can't all inside of sufficient lubrication roll body, particularly roll body top often can not get sufficient lubrication and causes upper end copper sheathing serious wear distortion, cause baffle plate to erect the roller fault, influenced the normal operation of tandem rolling unit.
Summary of the invention
Technical problem to be solved in the utility model provides the lubrication system of the perpendicular roller of a kind of tandem rolling unit baffle plate, utilize this structure to overcome the defective of the perpendicular roller lubrication system of traditional baffle plate, guarantee the sufficient lubrication of the perpendicular roller of baffle plate, avoid inordinate wear, improve the service life of the perpendicular roller of baffle plate, guaranteed the normal operation of tandem rolling unit.
For solving the problems of the technologies described above, the lubrication system of the perpendicular roller of the utility model tandem rolling unit baffle plate comprises roll body, bearing pin, oil inlet pipe and two copper sheathings, described bearing pin penetrates the roll body central through hole, described two copper sheathings are inserted in described bearing pin two ends respectively and are positioned at described roll body central through hole two ends, this structure also comprises two sealing rings, described two sealing rings are inserted in described bearing pin and lay respectively at described two copper sheathing end faces, described oil inlet pipe penetrates in the described bearing pin from described bearing pin top, and the oil outlet that is communicated with described oil inlet pipe is offered at the top of described bearing pin and middle part respectively.
Further, the oil outlet aperture on above-mentioned bearing pin top is greater than the oil outlet aperture at bearing pin middle part.
Because the lubrication system of the perpendicular roller of the utility model tandem rolling unit baffle plate has adopted technique scheme, be that this structure comprises roll body, bearing pin, oil inlet pipe and two copper sheathings, described bearing pin penetrates the roll body central through hole, described two copper sheathings are inserted in described bearing pin two ends respectively and are positioned at described roll body central through hole two ends, this structure also comprises two sealing rings, described two sealing rings are inserted in described bearing pin and lay respectively at described two copper sheathing end faces, described oil inlet pipe penetrates in the described bearing pin from described bearing pin top, and the oil outlet that is communicated with described oil inlet pipe is offered at the top of described bearing pin and middle part respectively.This structure has overcome the defective of the perpendicular roller lubrication system of traditional baffle plate, guarantees the sufficient lubrication of the perpendicular roller of baffle plate, avoids inordinate wear, has improved the service life of the perpendicular roller of baffle plate, guarantees the normal operation of tandem rolling unit.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of the perpendicular roller of traditional baffle plate;
Fig. 2 is the lubrication system schematic diagram of the perpendicular roller of the utility model tandem rolling unit baffle plate.
The specific embodiment
As shown in Figure 2, the lubrication system of the perpendicular roller of the utility model tandem rolling unit baffle plate comprises roll body 1, bearing pin 2, oil inlet pipe 4 and two copper sheathings 3, described bearing pin 2 penetrates roll body 1 central through hole, described two copper sheathings 3 are inserted in described bearing pin 2 two ends respectively and are positioned at described roll body 1 central through hole two ends, this structure also comprises two sealing rings 5, described two sealing rings 5 are inserted in described bearing pin 2 and lay respectively at described two copper sheathing 3 end faces, described oil inlet pipe 4 penetrates in the described bearing pin 2 from described bearing pin 2 tops, and the oil outlet 22 that is communicated with described oil inlet pipe is offered at the top of described bearing pin 2 and middle part respectively, 21.
Further, oil outlet 22 apertures on above-mentioned bearing pin 2 tops are greater than oil outlet 21 apertures at bearing pin 2 middle parts.
Two sealing rings of this structure play dustproof, in the time of the protecting against shock effect, prevent that grease from spilling from the gap location of copper sheathing and bearing pin easily, oil inlet pipe penetrates from the bearing pin top and can utilize gravity principle to make grease sufficient lubrication roll body inside, alleviate the copper sheathing degree of wear, prolong copper sheathing service life, two oil outlets offering at interval on the bearing pin utilize pressure principle to guarantee that grease can first sufficient lubrication roll body the first half lubricate the latter half again, make the grease can be in the inner Rational flow of roll body, avoid the unnecessary waste of grease, promote the lubricating efficiency of two copper sheathings, the perpendicular roller function of baffle plate is given full play to, avoided the perpendicular roller fault of baffle plate to reduce the production efficiency of tandem rolling unit.
