Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal lining plates, in particular to a high manganese steel centrifugal lining plate. Background Art

[0002] Centrifugal liners are industrial products, mainly used to protect the cylinder of the ball mill and improve grinding efficiency. According to the different lining materials, they can also be divided into metal liners, rubber liners, stone or cast stone liners, mixed liners, etc. Among them, high manganese steel centrifugal liners are the most common metal liners. Centrifugal casting of high manganese steel is a casting method in which liquid metal is poured into a rotating mold and the liquid metal is filled under the action of centrifugal force. To achieve the above process, a centrifugal casting machine must be used to create conditions for the mold to rotate. Centrifugal liners made of vertical centrifugal casting machines are used according to the different spatial positions of the mold's rotating axis.

[0003] High manganese steel centrifugal liner has become the preferred material in many industrial fields due to its excellent wear resistance, impact resistance, wide applicability, good processing performance and significant economic benefits. In the prior art, the main reason for the large wear of high manganese steel centrifugal liner in the ball mill cylinder is the loosening of its connecting bolts. The loose high manganese steel centrifugal liner in the ball mill cylinder will continue to loosen due to the impact of the material, causing increased wear. In severe cases, it may cause direct damage to the screw hole installation point in the ball mill cylinder. When the screw hole point in the ball mill cylinder is damaged, even replacing the high manganese steel centrifugal liner cannot solve the problem. Therefore, it is necessary to propose a high manganese steel centrifugal liner that is not easy to connect and loosen. For this purpose, we propose a high manganese steel centrifugal liner. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art and proposes a high manganese steel centrifugal lining.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A high manganese steel centrifugal liner, comprising a high manganese steel centrifugal liner main body structure, a connection structure and a reinforced threaded column structure; the high manganese steel centrifugal liner main body structure comprises a high manganese steel centrifugal liner seat, the high manganese steel centrifugal liner seat is provided with oblique ribs and longitudinal ribs, and the high manganese steel centrifugal liner seat, the oblique ribs and the longitudinal ribs are all provided with slots on their surfaces; the reinforced threaded column structure comprises a threaded column, a square hole is provided at the upper end of the threaded column, a round hole is provided on the inner side of the square hole, and a guide groove is provided at the bottom of the threaded column.

[0007] Preferably, the connection mechanism comprises a side ear seat, a threaded hole is formed on the inner side of the side ear seat, and the inner diameter of the threaded hole is adapted to the threaded column.

[0008] Preferably, four side ear seats are symmetrically arranged along both sides of the high manganese steel centrifugal liner seat.

[0009] Preferably, two oblique ribs are arranged along the surface of the high manganese steel centrifugal liner seat plate, and the two oblique ribs are crossed in a V shape.

[0010] Preferably, the high manganese steel centrifugal liner seat is an arc plate, and four longitudinal ribs are evenly distributed along the circumference of the arc edge of the high manganese steel centrifugal liner seat.

[0011] Preferably, the slots are evenly and densely distributed along the surface of the high manganese steel centrifugal liner seat, the oblique ribs and the longitudinal ribs.

[0012] Preferably, the circular hole passes through the square hole to the bottom of the threaded column, and the guide groove is connected to the bottom box of the circular hole.

[0013] Compared with the related art, the high manganese steel centrifugal liner proposed by the utility model has the following beneficial effects:

[0014] In the utility model, a high manganese steel centrifugal liner is described, through the high manganese steel centrifugal liner main body structure, in which oblique ribs and longitudinal ribs are arranged, which effectively strengthens the overall structural strength of the high manganese steel centrifugal liner, so that the high manganese steel centrifugal liner can withstand greater friction impact, and the cross distribution of the oblique ribs and the longitudinal ribs plus the evenly distributed slot hole setting greatly improves the surface roughness of the high manganese steel centrifugal liner, so that the high manganese steel centrifugal liner has a better grinding effect.

[0015] In the utility model, a high manganese steel centrifugal liner is provided with a reinforced threaded column mechanism, wherein the threaded column adopts a concave square hole setting. When the material hits the threaded column, since the outer ring of the threaded column is circular, it is difficult to cause a twisting effect on the threaded column during the impact, and most of the impact force is removed by the arc surface of the outer ring of the threaded column. In addition, a round hole is provided in the square hole, and the round hole passes through the threaded column, and a backflow groove is provided at the bottom of the threaded column, and the side of the guide groove also passes through several threads below the threaded column. When the threaded column is aligned with the installation point of the screw hole of the ball mill barrel, after tightening the threaded column, strong glue can be poured into the round hole, and the strong glue flows through the round hole to the installation point at the bottom of the threaded column, and penetrates upward along the guide groove, so that the installation point is filled with glue from the inside to the outside. When the glue solidifies, the connection strength of the threaded column is greatly improved, and it is difficult to fall off from the connection point, so that the installation of the high manganese steel centrifugal liner is more stable and the practicality is improved.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0021] Reference Figure 1-3 , please refer to Figure 1-Figure 3 ,in, Figure 1 This is a three-dimensional structural schematic diagram of a high manganese steel centrifugal liner proposed by the utility model; Figure 2 This is a schematic diagram of the three-dimensional split structure of a high manganese steel centrifugal liner proposed by the utility model; Figure 3 The utility model provides a three-dimensional structural diagram of a reinforcing threaded column mechanism of a high manganese steel centrifugal liner. A high manganese steel centrifugal liner comprises: a high manganese steel centrifugal liner main body mechanism 1, a connection mechanism 2 and a reinforcing threaded column mechanism 3; the high manganese steel centrifugal liner main body mechanism 1 comprises a high manganese steel centrifugal liner seat 11, and the high manganese steel centrifugal liner seat 11 is provided with oblique ribs 12 and longitudinal ribs 13, and the surfaces of the high manganese steel centrifugal liner seat 11, the oblique ribs 12 and the longitudinal ribs 13 are all provided with slots 14.

[0022] Through the above-mentioned arrangement, the staggered design of the oblique ribs 12 and the longitudinal ribs 13 effectively strengthens the overall structural strength of the high manganese steel centrifugal liner, so that the high manganese steel centrifugal liner can withstand greater friction impact. In addition, the cross distribution of the oblique ribs 12 and the longitudinal ribs 13 plus the evenly distributed slots 14 enable the high manganese steel centrifugal liner to grind materials in all directions, greatly improving the surface roughness of the high manganese steel centrifugal liner, so that the high manganese steel centrifugal liner has a better grinding effect.

[0023] In the present embodiment, the reinforced threaded column mechanism 3 includes a threaded column 31, a square hole 32 is opened at the upper end of the threaded column 31, a round hole 33 is opened inside the square hole 32, and a guide groove 34 is opened at the bottom of the threaded column 31. The round hole 33 passes through the square hole 32 to the bottom of the threaded column 31, and the guide groove 34 is connected with the bottom box of the round hole 33. It should be noted here that the two threads of the bottom of the threaded column 31 are penetrated by the side of the guide groove 34, and the number of the penetrated threads should not exceed two threads, so as to avoid affecting the screw connection strength of the bottom of the threaded column 31.

[0024] Through the above-mentioned arrangement, the circular hole 33 penetrates to the bottom of the threaded column 31 and is connected with the guide groove 34. When the threaded column 31 is installed, strong glue can be poured into the circular hole 33. The strong glue flows through the circular hole 33 to the installation point at the bottom of the threaded column 31, and penetrates upward along the guide groove 34, so that the installation point is filled with glue from the inside to the outside. When the glue solidifies, the connection strength of the threaded column 31 is greatly improved, and it is difficult to fall off from the connection point.

[0025] In this embodiment, the connection mechanism 2 includes a side ear seat 21, a threaded hole 22 is opened inside the side ear seat 21, the inner diameter of the threaded hole 22 is adapted to the threaded column 31, and four side ear seats 21 are symmetrically arranged along both sides of the high manganese steel centrifugal liner seat 11.

[0026] By the above arrangement, the side ear seats 21 are symmetrically arranged along both sides of the high manganese steel centrifugal liner seat 11, and the side ear seats 21 are distributed along the four corners of the high manganese steel centrifugal liner seat 11, so that the force on each connection point is uniform after the high manganese steel centrifugal liner seat 11 is installed.

[0027] In this method, two oblique ribs 12 are arranged along the plate surface of the high manganese steel centrifugal liner seat 11, and the two oblique ribs 12 are crossed in a V shape. The high manganese steel centrifugal liner seat 11 is an arc plate. Four longitudinal ribs 13 are evenly distributed along the circumference of the arc edge of the high manganese steel centrifugal liner seat 11. The slots 14 are evenly and densely distributed along the surface of the high manganese steel centrifugal liner seat 11, the oblique ribs 12 and the longitudinal ribs 13.

[0028] Through the above-mentioned arrangement, the arrangement of the oblique ribs 12 and the longitudinal ribs 13 is equivalent to the reinforcing ribs of the high manganese steel centrifugal liner seat 11, which improves the structural strength of the high manganese steel centrifugal liner seat 11 and enhances its impact resistance.

[0029] The working principle of a high manganese steel centrifugal liner provided by the utility model is as follows:

[0030] When in use, align the side ear seat 21 with the screw hole installation point in the ball mill barrel, and insert the threaded column 31 into the threaded hole 22 set in the side ear seat 21, tighten the threaded column 31 so that the bottom of the threaded column 31 is tightly screwed with the screw hole in the ball mill barrel. After the threaded column 31 is installed, strong glue can be poured into the round hole 33, and the strong glue flows through the round hole 33 to the installation point at the bottom of the threaded column 31, and penetrates upward along the guide groove 34, so that the installation point is filled from the inside to the outside. Full of glue, when the glue solidifies, the entire high manganese steel centrifugal liner can be normally stressed and used. During work, the staggered design of the oblique ribs 12 and the longitudinal ribs 13 effectively strengthens the overall structural strength of the high manganese steel centrifugal liner, so that the high manganese steel centrifugal liner can withstand greater friction impact. In addition, the cross distribution of the oblique ribs 12 and the longitudinal ribs 13 plus the evenly distributed slots 14 enable the high manganese steel centrifugal liner to grind materials in all directions, achieving a better grinding effect.

[0031] Compared with the related art, the high manganese steel centrifugal liner provided by the utility model has the following beneficial effects:
