Abstract
The utility model relates to a loading cantilevered roll way and roll shaft device, which comprises a first key (2), an inner tube (3), a water diversion block (4), a roller head (5), a second key (6), a hollow shaft (7), a water tube (8), a contact (9) and an end plate (10). The device is characterized in that the left end part of the roller head (5) is arranged with a baffle plate (11) and is fixed on the roller head (5); the right end of the roller head (5) is provided with a ring-shaped groove (12); a snap ring (13) is arranged corresponding to the ring-shaped groove (12); a spigot (14) is arranged on the hollow shaft (7); both the baffle plate (11) and the roller head (5) adopt the same ZG40Cr25Ni20Si2 high-temperature resistant material; and the baffle plate (11) is welded to the left end of the roller head (5). The utility model has the advantages of simple structure and long service life.
Description
Technical field
The utility model belongs to the metallurgical machinery equipment technical field, relates in particular to a kind of hanging arm roll roller device that goes out to feed.
Background technology
The hanging arm roll roller device that goes out to feed of rolling line, mainly by forming with the lower part: fixed block, a key, interior pipe, branch water piece, roller head, two keys, hollow shaft, joint and end plate are formed.During work, the roller head part is at high temperature worked, so the material of roller head and fixed block all adopts exotic material, the roller head is connected with hollow shaft with two keys by key one key, and together does gyration with hollow shaft.Fixed block is welded on the hollow shaft, prevents that the roller head is along the hollow shaft axial float.The material of hollow shaft and joint adopts the 20CrMo steel.For increasing the service life logical recirculated cooling water in hollow shaft and the joint.Branch water piece is equipped with in the inner left end of hollow shaft inside, and dividing the effect of water piece is that the water pipe in the water cavity is fixed, and makes it not swing with the rotation of hollow shaft.Left end is welded with end plate in the hollow shaft, and the right-hand member associated part of packing in use makes and forms airtight water cavity in the steel pipe.Dividing water piece and end plate material is Q235-A.Thisly go out to feed the hanging arm roll roller device after work a period of time, the roller head often occurs and come off and cooling water seepage phenomenon from hollow shaft.Through site inspection and internal structure analysis, find that roller head and fixed block are exotic material ZG40Cr25Ni20Si2, and hollow shaft 7 is the 20CrMo steel, dividing water piece and end plate material is Q235-A, welding performance is relatively poor.During work, roller head fixed block and end plate are under the condition of high temperature, and owing to the effect and the temperatures involved of external force, the weld seam between fixed block and the hollow shaft snaps easily during the revolution of roller head, cause the roller head loosening on hollow shaft, even come off.Weld seam between end plate and the hollow shaft produces fatigue rupture under above-mentioned influence simultaneously.So after using a period of time, cooling water seepage phenomenon occurs.
Summary of the invention
At the problems referred to above, task of the present utility model provides a kind of long service life, the hanging arm roll roller device that goes out to feed easy to make.The realization technical solution adopted in the utility model is: comprise a key, interior pipe, branch water piece, roller head, two keys, hollow shaft, water pipe, joint and end plate; The left part that it is characterized in that the roller head is provided with baffle plate and is fixed on the roller head, and the right-hand member of roller head is provided with cannelure, correspondingly with cannelure is provided with a pair of snap ring.On the said hollow shaft seam is set.The utility model is removed original fixed block, increase baffle plate, material adopts exotic material ZG40Cr25Ni20Si2, and be welded in the left end of roller head, because of roller head and the same material of baffle plate, adopt nickelic stainless steel electrode during welding, good welding performance, and weld seam is not subjected to the external force effect, avoids weld seam to cause the cooling water seepage because of fatigue rupture.Strengthened the diameter of axle size of hollow shaft left end, formed seam, the roller head is fixed on the hollow shaft by seam, prevent the roller head along hollow shaft left play, come off.On hollow shaft, be provided with cannelure, snap ring is snapped in wherein, and be welded on the hollow shaft.
The utility model has the advantages that simple in structure, long service life.
Description of drawings
Fig. 1 is the former hanging arm roll roller device structural representation that goes out to feed;
Fig. 2 is a structural representation of the present utility model;
Among the figure, 1, fixed block, 2, one key, 3, interior pipe, 4, divide the water piece, 5, the roller head, 6, two keys, 7, hollow shaft, 8, water pipe, 9, joint, 10, end plate, 11, baffle plate, 12, cannelure, 13, snap ring, 14, seam.
The specific embodiment
With reference to accompanying drawing, the utility model is described further.The utility model comprises a key 2, interior pipe 3, divides water piece 4, roller head 5, two keys 6, hollow shaft 7, water pipe 8, joint 9 and end plate 10; The left part that it is characterized in that roller head 5 is provided with baffle plate 11 and is fixed on the roller head 5, and the right-hand member of roller head 5 is provided with cannelure 12, correspondingly with cannelure 12 is provided with a pair of snap ring 13.On the said hollow shaft 7 seam 14 is set.The utility model is removed original fixed block 1, increases baffle plate 11, the ZG40Cr25Ni20Si2 exotic material that baffle plate 11 and roller head 5 adopt with material, and baffle plate 11 is welded in the left end of roller head 5.Because of roller head 5 and baffle plate 11 same materials, adopt nickelic stainless steel electrode during welding, good welding performance, and weld seam is not subjected to the external force effect, avoids weld seam to cause the cooling water seepage because of fatigue rupture.Strengthened the diameter of axle size of hollow shaft 7 left ends, formed seam 14, roller head 5 is fixed on the hollow shaft 7 by seam 14, prevent roller head 5 along hollow shaft 7 left play, come off.On hollow shaft 7, be provided with cannelure 12, snap ring 13 is snapped in wherein, and be welded on the hollow shaft 7.
