Abstract

The utility model relates to a supporting roller, in particular to a split type supporting roller which comprises a roller body, a roller core and roll shafts. The roller core is arranged in the roller body, the roll shafts are arranged at the two ends of the roller core, the roller body is of an up-down split type structure, the side edge of the upper portion and the side edge of the lower portion of the roller body are fixedly connected through a fixing plate, the fixing plate is fixedly connected with the upper portion and the lower portion of the roller body through bolts, fixing rods are arranged on the two sides of the upper portion and the two sides of the lower portion of the roller body respectively, and the fixing rods on the upper portion of the roller body and the fixing rods on the lower portion of the roller body are fixedly connected through a steel frame. Through the split type structure, when damage happens, only the damaged parts need to be replaced, cost is saved, and efficacy is improved.

Description

Separation type backing roll

Technical field

The utility model relates to a kind of backing roll, especially separation type backing roll.

Background technology

Backing roll is help roll conventional on a kind of milling train, and backing roll plays very important effect in Rolling Production, because the roll body of existing backing roll is integrated forming roll body, after roll body fracture occurs or damages, can only all change, and is unfavorable for cost-saving.

Utility model content

In order to overcome the high deficiency of existing backing roll maintenance cost, the utility model provides separation type backing roll.

The utility model solves the technical scheme that its technical problem adopts: separation type backing roll, comprise roll body, roller core and roll shaft, roller core is placed in roll body, and roller core two ends are provided with roll shaft, roll body is two-piece unit formula structure, and roll body top is fixedly connected with by fixed head with roll body bottom side.

According to another embodiment of the present utility model, further comprise that fixed head is fixedly connected with bottom with the top of roll body by bolt.

According to another embodiment of the present utility model, further comprise that the both sides, top of roll body and both sides, bottom are respectively equipped with fixed bar, are fixedly connected with by steelframe between the fixed bar on roll body top and the fixed bar of bottom.

The beneficial effects of the utility model are that this backing roll can utilize its split-type structural, only need to change the part of damage in the time being damaged, and has saved cost, has improved effect.

Brief description of the drawings

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is the structural representation of separation type backing roll;

1. roll bodies in figure, 2. roller core, 3. roll shaft, 4. fixed head, 5. bolt, 6. fixed bar, 7. steelframe.

Detailed description of the invention

If Fig. 1 is the structural representation of separation type backing roll, separation type backing roll, comprise roll body 1, roller core 2 and roll shaft 3, roller core 2 is placed in roll body 1, roller core 2 two ends are provided with roll shaft 3, roll body 1 is two-piece unit formula structure, roll body 1 top is fixedly connected with by fixed head 4 with roll body 1 bottom side, fixed head 4 is fixedly connected with bottom with the top of roll body 1 by bolt 5, both sides, top and the both sides, bottom of roll body 1 are respectively equipped with fixed bar 6, between the fixed bar 6 on roll body 1 top and the fixed bar 6 of bottom, are fixedly connected with by steelframe 7.

Roll body 1 is Split type structure, merge and form by upper and lower two parts, two parts side of roll body 1 uses bolt to carry out first by fixed head 4 and is fixedly connected with, then utilize steelframe 7 to fix the fixed bar 6 that connects upper and lower two parts side, and the two ends up and down of steelframe 7 are all provided with the axle collar, collar bush is located on fixed bar 6 and is fixedly connected with regard to the second that has completed roll body 1, when one of them in two parts up and down of roll body 1 is damaged, just as long as take successively two parts apart, then replacing with new roll body 1 just can work on, this backing roll can utilize its split-type structural, in the time being damaged, only need to change the part of damage, save cost, improve effect.
