Description

Technical Field

[0001] The utility model relates to the technical field of particle forming equipment, in particular to a high-efficiency wear-resistant ring die for particle forming equipment. Background Art

[0002] The ring die in traditional particle forming equipment usually has only one or two raceways, which causes the raw material to be compressed only once or twice during the forming process, resulting in low forming efficiency, and the formed particles may not be compact enough and are prone to looseness. In addition, due to the limitations of the materials and surface treatment technologies of the ring die and the pressure wheel, the wear resistance of these components is insufficient, and they are severely worn after long-term use and need to be frequently replaced, increasing the maintenance cost.

[0003] In view of these problems, existing technical solutions often have difficulty in taking into account both high-efficiency production and long-term use of the equipment. Therefore, it is necessary to develop a new type of high-efficiency wear-resistant ring die for particle forming equipment to solve the problems existing in the prior art. Summary of the Utility Model

The rotating shafts of the first pressure wheel and the second pressure wheel are respectively rotatably connected to the slot holes of the blocking positioning plate, and the ring die drives the first pressure wheel and the second pressure wheel to rotate clockwise respectively.

[0009] Preferably: The cooperation of the ring die with the first pressure wheel and the second pressure wheel enables the raw material to undergo two processes of pre-compaction and compaction extrusion forming in the first raceway, the second raceway and the third raceway.

The inner side of the ring die 1 includes a first raceway 4, a second raceway 5, and a third raceway 6, and the first raceway 4, the second raceway 5, and the third raceway 6 are provided with a first pressure wheel 2 and a second pressure wheel 3 corresponding to the three raceways;

[0024] The first pressure wheel 2 and the second pressure wheel 3 are respectively rotatably connected to the inner side of the ring die 1, and the first pressure wheel 2 and the second pressure wheel 3 are respectively rotatably connected to one end of the base 8.

[0025] It should be noted that the first pressure wheel 2 and the second pressure wheel 3 are respectively installed on the inner side of the ring die 1 by means of rotational connection, and one end of them is also connected to the base 8 by means of rotational connection. The first raceway 4, the second raceway 5, and the third raceway 6 are evenly distributed on the inner wall circumference of the ring die 1, which helps the raw materials to be evenly stressed during the forming process, thereby improving the forming efficiency and product quality. The base 8 provides support for the entire device and is connected to the ring die 1 and the first pressure wheel 2 and the second pressure wheel 3 by means of rotational connection, ensuring the stable operation of the device.

[0026] In an alternative embodiment: The first raceway 4, the second raceway 5, and the third raceway 6 are evenly distributed on the inner wall circumference of the ring die 1.

[0027] It should be noted that three raceways are provided on the inner side of the ring die 1, namely the first raceway 4, the second raceway 5, and the third raceway 6, and the three raceways are evenly distributed on the inner wall circumference of the ring die 1.

[0028] In an alternative embodiment: A blocking and positioning plate 7 is provided at the other end of the ring die 1. The rotating shafts of the first pressure wheel 2 and the second pressure wheel 3 are rotatably connected in the slot holes of the blocking and positioning plate 7, and the ring die 1 drives the first pressure wheel 2 and the second pressure wheel 3 to rotate clockwise respectively.

[0029] It should be noted that the blocking and positioning plate 7 is located at the other end of the ring die 1, which is used to fix the positions of the first pressure wheel 2 and the second pressure wheel 3 to ensure that they can accurately contact the raceway and apply pressure. The blocking and positioning plate 7 is provided with slot holes, and the rotating shafts of the first pressure wheel 2 and the second pressure wheel 3 pass through these slot holes for fixation.

[0030] In an alternative embodiment: The cooperation of the ring die 1 with the first pressing wheel 2 and the second pressing wheel 3 enables the raw material to undergo two processes of pre-compression and compression extrusion molding in the first raceway 4, the second raceway 5 and the third raceway 6.

[0031] It should be noted that the first pressing wheel 2 and the second pressing wheel 3 rotate clockwise driven by the ring die 1. Through the cooperation with the first raceway 4, the second raceway 5 and the third raceway 6, the raw material undergoes two processes of pre-compression and compression extrusion molding in the first raceway 4, the second raceway 5 and the third raceway 6.

[0032] In an alternative embodiment: The ring die 1 is made of high-grade nitriding steel material, and the first pressing wheel 2 and the second pressing wheel 3 are made of M300 steel after heat treatment. The surfaces of the ring die 1, the first pressing wheel 2 and the second pressing wheel 3 are nitrided.

[0033] It should be noted that the ring die 1 is made of high-grade nitriding steel material, which has good wear resistance and strength. The surface of the ring die 1 is nitrided to further improve its hardness and wear resistance. The first pressing wheel 2 and the second pressing wheel 3 are made of M300 steel and are heat-treated to enhance their hardness and toughness. The surfaces of the first pressing wheel 2 and the second pressing wheel 3 are also nitrided to ensure wear resistance during long-term use.

[0034] Working principle: The raw material is fed into the space position of the ring die 1, the first pressing wheel 2 and the second pressing wheel 3, and at this time the raw material is in an unprocessed state. When the raw material enters the first raceway 4, the first pressing wheel 2 starts to perform preliminary compression on the raw material. The first pressing wheel 2 applies a pre-compression force to the raw material through its cooperation with the first raceway 4, causing the raw material to start deforming and taking on a preliminary shape. The raw material continues to move forward and successively enters the second raceway 5 and the third raceway 6. In the second raceway 5, the second pressing wheel 3 starts to perform further compression on the raw material to increase the density of the raw material. When the raw material enters the third raceway 6, the second pressing wheel 3 continues to apply a greater pressure to complete the final shaping of the raw material. Through the continuous action of the first pressing wheel 2 and the second pressing wheel 3, the raw material undergoes a process from pre-compression to final compression extrusion molding in the three raceways. The first raceway 4, the second raceway 5 and the third raceway 6 evenly distributed on the inner wall circumference of the ring die 1 ensure that the raw material can receive uniform pressure at each stage. The first pressing wheel 2 and the second pressing wheel 3 rotate clockwise as the ring die 1 rotates, and gradually compress and form the raw material through contact with each raceway. The ring die 1 rotates under the action of the driving device, driving the first pressing wheel 2 and the second pressing wheel 3 to rotate together.

[0035] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than limiting them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present application.
