Description

Technical Field

[0001] The utility model relates to the technical field of rollers, in particular to a composite roller. Background Art

[0002] The main working parts and tools on the rolling mill that cause continuous plastic deformation of metal.

[0003] In the prior art, most rollers are made by one-piece turning. However, during use, the rollers are severely worn. Once the wear limit is reached, they can no longer be used and the entire roller is scrapped, resulting in a waste of resources. Rollers are cold rolled in the rolling process of plates and will generate a lot of heat when used. In the prior art, most of the heat dissipation is done by the outer surface of the roller. This method has a poor heat dissipation effect. The temperature of the roller will increase with the processing time. If the roller is not cooled in time, the processing quality of the plate to be rolled will be affected.

[0004] Therefore, the present application provides a composite roller to meet the demand. Utility Model Content

During the process of the roller sleeve rolling the plate, the heat generated can be exchanged and cooled with the external environment from the inside and outside of the roller sleeve, thereby improving the heat dissipation efficiency of the roller sleeve and maintaining its stable operation for a long time.

[0008] Preferably, the end plate is a T-shaped sleeve, which is sleeved on the roller core. The end plate is provided with a flange matching the size of the mounting groove. The end plate includes a head and a neck. The neck of the end plate is connected to the roller core by a fixing bolt, and the head of the end plate is connected to the side wall of the roller sleeve by a connecting bolt.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0026] refer to Figure 1-8A composite rolling roller shown in the figure comprises a roller shaft 1, a roller core 2 and a roller sleeve 3, wherein the roller shaft 1 is welded to both ends of the roller core 2 and the two are coaxially arranged; a through mounting groove 21 is provided on the roller core 2, and four groups of mounting grooves 21 are provided and are arranged in a circular array around the axis of the roller core 2. The mounting grooves 21 on the roller core 2 are arranged so that when the roller core 2 rotates, the supporting block 7 can be driven to rotate through the mounting grooves 21, thereby driving the roller sleeve 3 to rotate and realizing the rolling processing of the plate. The supporting block 7 is slidably connected to the roller core 2, and the supporting block 7 is also engaged with a limiting bolt 8 for limiting the position with the roller core 2. The supporting block 7 is provided with multiple groups, and is limited on the roller core 2 by the limiting bolts 8, so as to facilitate the subsequent installation of the roller sleeve 3.

[0027] The roller sleeve 3 is also sleeved on the roller core 2, and the roller core 2 is provided with a support block 7 for supporting the inner wall of the roller sleeve 3, and the support block 7 is provided in multiple groups; the support block 7 includes a sleeve body 73, a protrusion 71 and a support portion 72, the sleeve body 73 is sleeved on the roller core 2, the protrusion 71 is provided on the facing surface of the support block 7 and the roller core 2, and matches the size of the mounting groove 21, the support portion 72 is used for supporting the roller sleeve 3, the protrusion 71 and the support portion 72 are provided on the inner and outer sides of the sleeve body 73, the protrusion 71 is used for clamping with the roller core 2, and the support portion 72 is used for supporting and clamping the roller sleeve 3.

[0028] The inner wall of the roller sleeve 3 is provided with ribs 31, and there are multiple ribs 31, two of the ribs 31 form a group, and a support groove 32 is formed between the two ribs 31. The support groove 32 corresponds to the support portion 72 of the support block 7 in position and matches in size. The support groove 32 is provided to cooperate with the support portion 72 on the support block 7, so that the roller core 2 drives the support block 7 to rotate, thereby driving the roller sleeve 3 to rotate.

[0029] The roller core 2 is provided with an end plate 4 which closes both ends of the roller sleeve 3. The end plate 4 is provided with a heat dissipation hole 41. The heat dissipation hole 41 connects the inside of the roller sleeve 3 with the outside. The opening of the heat dissipation hole 41 connects both the inside and outside of the roller sleeve 3 with the external environment, thereby improving the heat dissipation efficiency of the roller sleeve 3 and enabling it to maintain stable operation for a long time.

[0030] The end plate 4 is a T-shaped sleeve, which is sleeved on the roller core 2. The end plate 4 is provided with a flange 42 that matches the size of the mounting groove 21. The end plate 4 includes a head and a neck. The neck of the end plate 4 is connected to the roller core 2 by a fixing bolt 6, and the head of the end plate 4 is connected to the side wall of the roller sleeve 3 by a connecting bolt 5. The setting of the end plate 4 can make the connection between the roller core 2 and the roller sleeve 3 more stable, and at the same time can also play a role in limiting the support block 7, so as to avoid the limiting bolt 8 from limiting the support block 7 firmly, so that the support block 7 slides out of the roller sleeve 3 and cannot support the roller sleeve 3.

[0031] The utility model works as follows: during installation, the protrusion 71 on the support block 7 is aligned with the installation groove 21 on the roller core 2 for installation. According to the length of the roller sleeve 3, the number of support blocks 7 to be installed is determined, and the support block 7 and the roller core 2 are limited by the limit bolt 8. After the support block 7 is installed, the roller sleeve 3 is installed so that the support groove 32 on the roller sleeve 3 is aligned with the support portion 72 on the support block 7 for installation, and the support portion 72 is embedded in the support groove 32 on the roller sleeve 3, and then the end plate 4 is installed so that the convex edge 42 on the end plate 4 is aligned with the installation groove 21 on the roller core 2 for installation, so that the head of the end plate 4 is in contact with the side wall of the roller sleeve 3, and the end plate 4 is limited by the connecting bolt 5, and then the end plate 4 is connected and limited to the roller core 2 by the fixing bolt 6, and the assembly and installation of the roller is completed.

[0032] When in use, the roller shaft 1 is driven to rotate by the motor, thereby driving the roller sleeve 3 to rotate to achieve rolling of the plate. Since heat is generated during the cold rolling process, the temperature of the roller sleeve 3 increases during use, and the temperature of the roller sleeve 3 is higher than the temperature of the external environment. The outer surface of the roller sleeve 3 exchanges heat with the external environment. Since there is a cavity between the inner wall of the roller sleeve 3 and the roller core 2, and the heat dissipation holes 41 on the end plate 4 connect this cavity with the external environment, the inner wall of the roller sleeve 3 can also achieve heat exchange operation with the external environment through the heat dissipation holes 41, thereby accelerating the heat exchange speed of the roller sleeve 3, so that it can roll the plate for a long time.
