Description

High-abrasion-resistance high-accident-resistance two-intermediate roller

Technical Field

The utility model relates to a roller in the middle of two, concretely relates to roller in the middle of two of high rigidity, high wearability and high anti accident.

Background

At present, the similar rollers at home and abroad are made of 5H12 materials, the required hardness is achieved through integral heat treatment, the silicon steel kilometers are rolled at one time, the rollers have the defects of poor fatigue resistance, peeling and the like at different degrees, and the development of two intermediate rollers with high performance and high cost performance is urgently needed.

Disclosure of Invention

The purpose of the invention is as follows: the invention aims to overcome the defects in the prior art and provide the two intermediate rolls which have high integral hardness, good wear resistance, accident resistance improved by more than 1.5 times compared with the traditional rolls and long service life.

The technical scheme is as follows: in order to solve the technical problem, a high two middle rollers of high abrasion resistance accident resistance, it includes barrel and main shaft the barrel surface is equipped with a plurality of archs barrel and protruding outside cladding are equipped with the polyurethane rubber layer, polyurethane rubber layer interval sets up in the barrel surface, is equipped with the clearance between two liang of polyurethane rubber layers polyurethane rubber layer surface is equipped with the wire groove the outside cladding of main shaft is equipped with the butadiene acrylonitrile rubber layer outside is equipped with the lug.

Further, the thickness of the nitrile-butadiene rubber layer is smaller than the radius of the end face of the cylinder body.

Further, the width of the gap is 0.6-1.2 cm.

Has the advantages that: compared with the prior art, the utility model, it is showing the advantage and is: the utility model has the advantages of reasonable overall structure, the barrel adopts the improvement material, and through process optimization, obtain the high rigidity, roller in the middle of two high wear-resisting, in order to reach the permanent labour and anti accident resistance of roll, whole hardness can reach 80-83HSD, whole hardness homogeneity is less than or equal to 1HSD, anti accident resistance can improve more than 1.5 times than traditional roll, play the purpose of keeping away water with barrel and main shaft surface cladding polyurethane rubber layer and the fine glue layer of butyl, it is fixed to adopt the lug simultaneously, solve above-mentioned both fixed and connect untight problem, through setting up polyurethane rubber layer interval, reserve reasonable liquid path passageway, and set up the flow that linear groove improves liquid outside polyurethane rubber layer.

fig. 2 is a schematic structural diagram of the middle cylinder, the main shaft and the protrusions of the present invention.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

As shown in fig. 1 and 2, a two intermediate rolls of high abrasion resistance and high accident resistance, it includes barrel 1 and main shaft 2 barrel 1 surface is equipped with a plurality of archs 3 barrel 1 and the protruding 3 outside cladding of arch are equipped with polyurethane rubber layer 4, polyurethane rubber layer 4 interval sets up in barrel 1 surface, is equipped with clearance 5 between two liang of polyurethane rubber layers 4, the width of clearance 5 is 0.6-1.2cm polyurethane rubber layer 4 surface is equipped with wire groove 6 main shaft 2 outside cladding is equipped with butadiene acrylonitrile rubber layer 7, the thickness of butadiene acrylonitrile rubber layer 7 is less than the radius of barrel 1 terminal surface the butadiene acrylonitrile rubber layer 7 outside is equipped with lug 8. The utility model has the advantages of reasonable overall structure, the barrel adopts the improvement material, and through process optimization, obtain the high rigidity, roller in the middle of two high wear-resisting, in order to reach the permanent labour and anti accident resistance of roll, whole hardness can reach 80-83HSD, whole hardness homogeneity is less than or equal to 1HSD, anti accident resistance can improve more than 1.5 times than traditional roll, play the purpose of keeping away water with barrel and main shaft surface cladding polyurethane rubber layer and the fine glue layer of butyl, it is fixed to adopt the lug simultaneously, solve above-mentioned both fixed and connect untight problem, through setting up polyurethane rubber layer interval, reserve reasonable liquid path passageway, and set up the flow that linear groove improves liquid outside polyurethane rubber layer.

The utility model provides a thinking and method, the method and the way of specifically realizing this technical scheme are many, above only the utility model discloses a preferred embodiment should point out, to the ordinary technical personnel in this technical field, not deviating from the utility model discloses under the prerequisite of principle, can also make a plurality of improvements and moist decorations, these improvements should also be regarded as the utility model discloses a protection range, each component that does not make clear and definite in this embodiment all can be realized with prior art.
