Description

Aluminum alloy roller for roller mill

[ technical field ] A method for producing a semiconductor device

The utility model relates to a roll mill equipment technical field especially relates to an aluminum alloy roller for roll mill.

[ background of the invention ]

The rolling mill is a machine which feeds a casting blank by a feeding device and rolls the casting blank into a square, rectangular or circular section blank with a certain size by a roller, two ends of the roller are arranged in bearing blocks, and the bearing blocks are arranged on a rolling mill frame. The roller is the most important part in the rolling mill, and the quality of the roller determines the quality of the product. During the operation of the rolling mill, the rolls are in contact with the material and apply pressure to the material for processing. When the roller is used for a long time, the surface of the roller is easily corroded or damaged, and pits appear on the surface, so that the surface of a processed product is not smooth enough. Meanwhile, the roll core of the roll is easy to break under the action of long-term high pressure, and the maintenance cost of the equipment is high. In the prior art, a protective layer is generally added on the outer side of a roller, so that a certain protective effect is achieved on the roller core and the surface of the roller. However, the structure arrangement has limited protection effect, the rollers are integrally arranged, and the rollers can only be completely replaced after being damaged, so that the maintenance cost is high. Therefore, there is a need for a new type of roll having excellent corrosion resistance, high structural stability, and resistance to damage. In addition, the maintenance cost after the roller is damaged is low, and the maintenance operation is simple.

3, 1 both ends in axle center are equipped with fixed axle 11, aluminum alloy roller still includes elastic protection layer 2, cladding material 4 and clamping screw 5, be equipped with on 1 outer wall in axle center elastic protection layer 2, be equipped with on 1 outer wall in axle center fixture block 12 that runs through elastic protection layer 2, be equipped with screw hole 121 on the fixture block 12, outer roller 3 comprises two the same semicircle rings, be equipped with on 3 outer roller with the fixture block 12 correspond draw-in groove 32 and with the fixed orifices 31 that screw hole 121 corresponds, be equipped with on 3 outer wall in outer roller cladding material 4, clamping screw 5 passes screw hole 121 with fixed orifices 31, outer roller 3 is the aluminum alloy roller. Specifically, the outer roller 3 is composed of two identical semicircular rings, so that the aluminum alloy roller can be changed into a plurality of detachable parts, and different parts can be conveniently maintained and replaced. The elastic protection layer 2 plays a role in shock absorption, protects the shaft center 1 and also improves the connection stability of the shaft center 1 and the outer roller 3. Because the elastic protection layer 2 is located between the shaft center 1 and the outer roller 3, and applies elastic force to the shaft center 1 and the outer roller 3, the fixing screw 5 located in the screw hole 121 and the fixing hole 31 is more stable. The axle center 1 and the outer roller 3 are connected more closely, so that the aluminum alloy roller is more stable in working, processed products are more smooth, and meanwhile, the aluminum alloy roller is not easy to damage. The outer roller 3 consists of two identical semicircular rings, and the joints of the semicircular rings may cause the machined product to be not smooth enough. The plating layer 4 is to solve this problem, and the plating layer 4 also has an effect of protecting the outer roll 3. Only need regularly change cladding material 4, can greatly reduced the probability that outer roller 3 damaged has reduced the cost of maintenance of aluminum alloy roller. The aluminum alloy has high corrosion resistance, certain strength, firmness and durability. This aluminum alloy roller adopts set screw 5 connects axle center 1 with outer roller 3, and it should further be explained that thereby it reaches above-mentioned effect to adopt other parts, and the reason should all belong to the utility model discloses an within the inventive concept, and the reason should belong to the utility model discloses a within the scope of protection.

The elastic protection layer 2 is made of rubber, and the rubber has good elasticity and is stable and durable.

The number of the clamping blocks 12 is not less than 4, and the number of the screw holes 121 on each clamping block 12 is not less than 2. Specifically, the fixture block 12 and the screw hole 121 are connected with the shaft center 1 and the outer roller 3, and are stress points at the connection position, and the number of the fixture block 12 and the screw hole 121 is increased, so that the aluminum alloy roller is more stable and is not easy to damage.

The outer wall of the fixed shaft 11 is provided with a fixed block 111 and/or a fixed groove 112. Specifically, the fixed shaft 11 is used for being connected with a bearing seat of a rolling mill and is a connection point of an aluminum alloy roller and the rolling mill. The fixing block 111 and/or the fixing groove 112 are/is arranged, so that the structural strength of a connecting point of the aluminum alloy roller and a rolling mill can be improved, and the aluminum alloy roller can work more stably.

The outer roller 3 and the elastic protection layer 2 are in frictional contact. Specifically, the roll squeezer during operation, axle center 1 can drive outer roller 3 rotates, outer roller 3 with the increase of 2 contact surface frictional force of elastic protection layer can increase the power that outer roller 3 received reduces the atress intensity of fixture block 12 makes the aluminum alloy roller more stable, and is not fragile.

Referring to fig. 4, a water inlet channel 13 and a water outlet channel 14 are disposed in the shaft center 1, the elastic protection layer 2 is provided with a groove 21, a pipeline 22 is disposed in the groove 21, two ends of the pipeline 22 are respectively connected to the water inlet channel 13 and the water outlet channel 14, the groove 21 is spirally disposed along the shaft center 1, and the water inlet channel 13 and the water outlet channel 14 are disposed at two opposite ends of the shaft center 1. Specifically, the grooves 21 and the pipelines 22 are arranged to achieve a cooling effect on the aluminum alloy roller. The friction heat generation when the aluminum alloy roller works, and the long-term high-temperature work can damage the aluminum alloy roller. Therefore, a cooling device is required to prevent the elastic protection layer 2, the shaft core 1, and the outer roll 3 from being deformed and damaged. The grooves 21 are spirally arranged along the shaft center 1, so that the cooling area is large, the cooling effect of each part can be consistent, and the damage of the parts caused by large temperature difference of different parts can be prevented.

The working principle is as follows: the elastic protection layer 2 is installed on the outer wall of the shaft center 1, the clamping groove 32 of the outer roller 3 and the shaft center 1 are correspondingly installed on the clamping block 12, and then the fixing screw 5 is installed through the screw hole 121 and the fixing hole 31. The plating layer 4 is mounted on the outer wall of the outer roller 3. Finally, the aluminum alloy roller is arranged on a roller mill through the fixed shaft 11, and the roller mill is started to process the raw materials. After the parts of the aluminum alloy roller are damaged, the plating layer 4 is removed, and the fixing screw 5 is screwed off, so that each part can be maintained and replaced.

While the embodiments of the invention have been disclosed above, it is not limited to the applications set forth in the description and embodiments, but is capable of being applied in all kinds of fields adapted to the invention, and further modifications may readily be made by those skilled in the art, and the invention is therefore not limited to the details shown and described herein, without departing from the general concept defined by the claims and their equivalents.
