Description
Technical Field
The utility model belongs to the technical field of rolling former part technique and specifically relates to relate to rolling forming roller.
Background
In industrial production, when powder materials are manufactured into particles, a rolling forming machine is often used for rolling and forming the powder, the rolling forming machine has a frame, and a pair of rolling forming rollers is arranged in the frame. The roller compaction forming roller comprises a central shaft core, a roller sleeve is arranged on the periphery of the shaft core, and a plurality of forming grooves are formed in the outer surface of the roller sleeve. When the particles are formed, the powder passes between the two rolling forming rollers, and the powder is formed in the forming groove.
In the prior art, the roller compaction forming roller is of an integrated structure, namely, the shaft core and the roller sleeve are of an integrated structure, when the roller compaction forming roller is used, the surface of the roller sleeve bears larger pressure and is worn quickly, and when the surface of the roller sleeve is worn, the roller compaction forming roller needs to be replaced integrally, so that the defects of high use cost and waste are caused.
Disclosure of Invention
The utility model aims at providing a need not wholly change the split type forming roller that rolls into the grooved roll, reduce use cost after its surface wear exactly to above-mentioned shortcoming.
The technical scheme of the utility model is realized like this: a split type rolling forming roller comprises a central shaft core and a roller sleeve arranged on the periphery of the shaft core, wherein a plurality of forming grooves are formed in the outer surface of the roller sleeve; the method is characterized in that: the roller sleeve is internally matched and arranged outside the shaft core, key grooves with length directions along the center of the shaft core are arranged on the inner surface of the roller sleeve and the outer surface of the shaft core, and keys are arranged in the key grooves.
Furthermore, the outer surfaces of the two ends of the shaft core are provided with threads, locking nuts are arranged on the threads, and after the two locking nuts are arranged, the locking nuts are arranged at the two ends of the roller sleeve.
Further, the shaft core comprises a central core and a middle sleeve arranged on the periphery of the central core, the middle sleeve is of a cylindrical structure and is sleeved outside the central core, a second key groove with the length direction along the direction of the shaft core is arranged between the inside of the middle sleeve and the outside of the central core, and a second key is arranged in the second key groove.
The beneficial effects of the utility model reside in that: the split type rolling forming roller has the advantages that the rolling forming roller does not need to be integrally replaced after the surface of the roller is abraded, and the use cost is reduced;
the outer surfaces of the two ends of the shaft core are provided with threads, locking nuts are arranged on the threads, and after the two locking nuts are arranged, the locking nuts are arranged at the two ends of the roller sleeve and have the advantage that the two ends of the roller sleeve can be positioned;
the shaft core comprises a central core and a middle sleeve arranged on the periphery of the central core, the middle sleeve is of a cylindrical structure and is sleeved outside the central core, a second key groove is arranged between the inside of the middle sleeve and the outside of the central core along the direction of the shaft core in the length direction, a second key is arranged in the second key groove, and the shaft core further has the advantage that different parts can be replaced according to the loss degree.
Drawings
Fig. 1 is a schematic side view of the present invention.
Fig. 2 is a schematic sectional view of the present invention.
Wherein: 1. the roller comprises a shaft core 2, a roller sleeve 3, a forming groove 4, a key 5, a thread 6, a locking nut 11, a central core 12, an intermediate sleeve 13 and a second key.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 and 2, a split type roller compaction forming roller comprises a central shaft core 1 and a roller sleeve 2 arranged on the periphery of the shaft core, wherein the outer surface of the roller sleeve is provided with a plurality of forming grooves 3; the method is characterized in that: the shaft core and the roller sleeve are of a split structure, the roller sleeve 2 is of a cylindrical structure, the outer surface of the shaft core 1 is of a cylindrical structure, the roller sleeve is internally installed outside the shaft core in a matched mode, key grooves with length directions along the center direction of the shaft core are formed in the inner surface of the roller sleeve 2 and the outer surface of the shaft core, and keys 4 are installed in the key grooves.
The working principle of the utility model is as follows: the mould pits of two rollers of the pair roller are mutually corresponding and arranged on the equipment, and the external power device provides power to enable the rollers to rotate in a centering way, after the products are repeatedly rolled by the pair roller, due to the pressure between the pair rollers, the materials can be rolled into the products with the same shape and size as the mould pits on the surface of the roller sleeve, after the products are used for a period of time, the mould pits on the surface of the pair roller can be deformed and damaged due to long-time extrusion, at the moment, the roller sleeve can be only required to be replaced, and compared with the prior art, the whole pair roller can be replaced completely, so that the partial cost can be saved.
Furthermore, the outer surfaces of two ends of the shaft core are provided with threads 5, locking nuts are arranged on the threads, and after the two locking nuts 6 are arranged, the locking nuts are arranged at two ends of the roller sleeve 2.
In this way, it is easier to position the sleeve.
Further, the shaft core 1 includes a central core 11 and a central sleeve 12 around the central core, the central sleeve 12 is cylindrical and is sleeved outside the central core 11, a second key groove is formed between the inside of the central sleeve 12 and the outside of the central core 11 along the length direction of the shaft core, and a second key 13 is arranged in the second key groove.
Thus, the middle sleeve and the like can be replaced according to the damage degree.
Although the present invention has been described with reference to the accompanying drawings, it is not intended to limit the scope of the present invention, and those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without inventive work are still within the scope of the present invention.
