Description

Technical Field

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

[0002] The main working component and tool on a rolling mill that causes continuous plastic deformation of metal. The roll consists of three main parts: the roll body, the roll neck, and the shaft head. The roll body is the middle part of the roll that actually rolls the metal.

[0003] After long-term use, the surface of the roller is prone to wear and cracks. If the entire roller is replaced directly, it will be time-consuming and labor-intensive, increase production costs, and affect work efficiency. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a novel composite roller for solving the technical problem that the existing roller needs to be replaced as a whole after being worn, which reduces the working efficiency.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A new type of composite rolling roller includes a roller body, two limit bars are symmetrically fixed on the outer periphery of the roller body, a shell for rolling raw materials is sleeved on the outer periphery of the roller body, two limit grooves corresponding to the two limit bars are opened on the inner wall of the shell, and two first support blocks for limiting the movement of the shell are sleeved on the outer periphery of the roller body, and one end of the two first support blocks abuts against the end faces of both sides of the shell.

[0007] Working principle:

[0008] When the outer periphery of the shell is worn and needs to be replaced, one of the first support blocks is removed from the roller body, the shell is slid relative to the roller body, the shell is removed from the roller body, and a new shell is replaced. The removed first support block is re-fixed on the roller body, and the two first support blocks fix the shell.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. When the shell is worn and needs to be replaced, there is no need to replace the entire roller, only the shell needs to be replaced, which reduces production costs;

[0011] 2. When replacing the shell, one of the first supporting blocks is removed from the roller body to replace the shell, which speeds up the replacement of the shell and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0017] Example:

[0018] like Figure 1 and Figure 2 As shown, a new type of composite roller includes a roller body 17, two limit bars 15 are symmetrically fixed on the outer periphery of the roller body 17, a shell 16 for rolling the raw material is provided on the outer periphery of the roller body 17, two limit grooves 14 corresponding to the two limit bars 15 are opened on the inner wall of the shell 16, and two first support blocks 24 for limiting the movement of the shell 16 are provided on the outer periphery of the roller body 17, one end of the two first support blocks 24 is abutted against the end faces of the shell 16 on both sides, and roller shafts 10 are fixed on the end faces of both sides of the roller body 17. When the roller needs to be used, the roller is set on the machine through the two roller shafts 10, and the machine drives the entire roller to rotate through the roller shaft 10, thereby rolling the raw material.

[0019] When the outer periphery of the shell 16 is worn and needs to be replaced, one of the first support blocks 24 is removed from the roller body 17, the shell 16 is slid relative to the roller body 17, the shell 16 is removed from the roller body 17, and a new shell 16 is replaced. The removed first support block 24 is re-solidified on the roller body 17, and the two first support blocks 24 fix the shell 16. When the shell 16 is worn and needs to be replaced, there is no need to replace the entire roller, only the shell 16 needs to be replaced, which reduces production costs.

[0020] When replacing the shell 16 , one of the first support blocks 24 is removed from the roller body 17 , and the shell 16 can be replaced, thereby accelerating the replacement speed of the shell 16 and improving work efficiency.

[0021] like Figure 1As shown, two groups of threaded holes 20 are provided on the roller body 17, and each group of threaded holes 20 includes two. Each first support block 24 is provided with two limiting holes 22. A screw 19 with a nut is rotated through each limiting hole 22, and the screw 19 extends into the corresponding threaded hole 20 to connect with the internal thread 11. The screw 19 is screwed in to fix the first support block 24.

[0022] Both side end surfaces of the housing 16 have inclined portions 23 , and one end of the first supporting block 24 is fixedly provided with an abutting block 18 that cooperates with the inclined portion 23 .

[0023] like Figure 1 and Figure 3 As shown, two recessed portions 21 are provided on the outer periphery of the shell 16, and external threads are provided on the recessed portions 21. Two second support blocks 12 are sleeved on the outer periphery of the shell 16, and internal threads 11 are provided on the inner walls of the second support blocks 12. The internal threads 11 cooperate with the external threads. After the second support blocks 12 are rotated, the second support blocks 12 cooperate with the recessed portions 21.

[0024] A third support block 13 is fixed to one end of each second support block 12 . The inner wall of the third support block 13 abuts against the outer periphery of the first support block 24 . The third support block 13 blocks the limiting hole 22 , further increasing the stability of the second support block 12 .

[0025] Working principle:

[0026] When the shell 16 needs to be replaced, first rotate one of the second support blocks 12 to remove the second support block 12 from the roller body 17, then loosen the two screws 19 on the same side, take out the two screws 19 from the threaded holes 20, remove the first support block 24 from the roller body 17, remove the shell 16, replace it with a new shell 16, put the first support block 24 on the outer periphery of the roller body 17, screw in the two screws 19, and finally screw in the second support block 12.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
