DETAILED DESCRIPTION

[0020] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0021] Reference Figure 1-4 A new type of guide wheel includes a wheel body 1, which includes an outer wheel 11 and an inner wheel 14. The inner cavity of the outer wheel 11 is equidistantly provided with plum blossom grooves 13, and the outer side of the inner wheel 14 is equidistantly provided with plum blossom protrusions 15 that fit therewith. A bearing hole 17 is provided in the middle of the inner wheel 14, and a groove 12 is provided on the outer side of the wheel body 1. The outer wheel 11 is made of tungsten steel material, and the inner wheel 14 is made of a mixture of water glass and alumina.

[0022] The outer wheel 11 made of tungsten steel material effectively improves the hardness and wear resistance, and can maintain a high hardness when used at high temperatures. The designed groove 12 facilitates subsequent transmission use, and the inner wheel 14 made of a mixture of water glass and alumina has low thermal conductivity as a solid substance of water glass and alumina, which reduces heat loss during processing and effectively reduces the heat absorbed by the guide wheel when in use. The heat loss of the workpiece is effectively reduced, and the transmission effect of the guide wheel is improved. The method is achieved by mixing water glass and water in a ratio of 1:2-4, and then mixing the water glass solution and alumina powder in a ratio of 1:2-3 into a paste, and then putting it into a mold together with a tungsten steel ring for die casting to form a mold blank. First, the temperature in the furnace is raised to 150-220°C and kept warm for 0.5-1h to evaporate the water in the mixture. Then, the temperature is raised to 300-350°C at 10°C / min and sintered for 1-1.5h to remove the crystalline water in the water glass and transform the glassy state of sodium silicate to bond the tungsten steel ring and alumina together, thereby combining the plum blossom groove 13 on the inner side of the wheel body 1 with the plum blossom bump 15 on the outer side of the inner wheel 14, thereby effectively improving the composite firmness of the guide wheel and effectively improving its service life.

[0023] An insulation component is installed on both sides of the inner wheel 14, and the insulation component includes a first side plate 2 and a second side plate 3 arranged on both sides of the inner wheel 14. A slot 18 is arranged on both sides of the wheel body 1, and the first side plate 2 and the second side plate 3 are both clamped in the inner cavity of the slot 18.

[0024] Four slots 16 are equidistantly arranged on the outer side of the inner wheel 14, and the outer side of the first side disc 2 is integrally connected with four plug-in blocks 8 plugged therein, and the outer side of the first side disc 2 is integrally connected with an external threaded sleeve 6, which is located in the inner cavity of the bearing hole 17, and one side of the second side disc 3 is integrally connected with a bearing sleeve 4, which is inserted into the inner cavity of the bearing hole 17, and the bearing sleeve 4 is located in the inner cavity of the external threaded sleeve 6, and the inner cavity of the external threaded sleeve 6 fits with the outer side of the bearing sleeve 4, and the outer side of the bearing sleeve 4 is fixedly sleeved with an internal threaded sleeve 5 screwed to the external threaded sleeve 6.

[0025] The outer side of the bearing sleeve 4 is movably sleeved with a heat-insulating sleeve 7, the outer diameter of which matches the inner cavity size of the bearing hole 17, and the heat-insulating sleeve 7 is made of high-temperature resistant heat-insulating cotton material.

[0026] The first side plate 2 and the second side plate 3 are provided with mounting grooves on their corresponding sides. Gaskets 9 are installed in the inner cavities of the mounting grooves. The gaskets 9 are made of high-temperature resistant rubber material. The outer surfaces of the first side plate 2 and the second side plate 3 are sprayed with thermal insulation paint.

[0027] The first side disc 2 is inserted into the slot 16 on the outside of the inner wheel 14 by using the insert block 8. At the same time, the external threaded sleeve 6 on one side of the first side disc 2 is inserted into the inner cavity of the bearing hole 17. Subsequently, the outer sides of the bearing sleeve 4 and the internal threaded sleeve 5 are covered with the insulation sleeve 7. As the bearing sleeve 4 and the internal threaded sleeve 5 on one side of the second side disc 3 are inserted into the inner cavity of the bearing hole 17 together with the insulation sleeve 7, and then the second side disc 3 is rotated, and then the second side disc 3 drives the internal threaded sleeve 5 to rotate. The internal threaded sleeve 5 is threadedly rotated on the outside of the external threaded sleeve 6, so that the internal threaded sleeve 5 and the external threaded sleeve 6 are threadedly connected, until the second side disc 3 fits into the groove 18 on the outside of the outer wheel 11, the installation of the first side disc 2 and the second side disc 3 is completed. At this time, the bearing sleeve 4 moves the inner side of the external threaded sleeve 6 to facilitate the subsequent installation of the bearing, and the first side disc 2 and the second side disc 3 are installed with gaskets 9 through the installation grooves, which effectively improves the firmness of their installation, and the gasket 9 made of high-temperature resistant rubber material effectively improves its service life, and the insulation sleeve 7 made of high-temperature resistant heat-insulating cotton material is put on the outer side of the bearing sleeve 4 and the internal threaded sleeve 5, which effectively improves the insulation effect and reduces the heat transfer from the inner wheel 14 to the outside, and the first side disc 2 and the second side disc 3 are designed to be sprayed with heat-insulating paint on the outer surface, which further improves the heat insulation effect, avoids the heat dissipation too fast, effectively reduces the thermal conductivity, reduces the heat loss of the workpiece, and improves the use effect of this guide wheel.

[0028] Working principle: When the utility model is in use, the outer wheel 11 made of tungsten steel material can effectively improve the hardness and wear resistance, so that it can still maintain a high hardness when used in high temperature. The inner wheel 14 made of a mixture of water glass and alumina has a low thermal conductivity as a solid material of water glass and alumina, which reduces the heat loss during processing, effectively reduces the heat absorbed by the guide wheel when in use. The heat loss of the workpiece is effectively reduced, and the transmission effect of the guide wheel is improved. The first side plate 2 is inserted into the slot 16 on the outside of the inner wheel 14 by using the plug block 8. At the same time, the external threaded sleeve 6 on one side of the first side plate 2 is inserted into the inner cavity of the bearing hole 17. Then, the insulation sleeve 7 is put on the outer side of the bearing sleeve 4 and the internal threaded sleeve 5, and then the second side plate 3 is rotated, so that the second side plate 3 drives the internal threaded sleeve 5 to rotate and rotates with the external threaded sleeve 6 Screw connection until the second side disc 3 fits with the slot 18 on the outside of the outer wheel 11, completing the installation of the first side disc 2 and the second side disc 3. At this time, the bearing sleeve 4 moves the inner side of the outer threaded sleeve 6 to facilitate the subsequent installation of the bearing, and the first side disc 2 and the second side disc 3 are installed with the gasket 9 through the installation groove, which effectively improves the firmness of its installation, and the gasket 9 made of high-temperature resistant rubber material effectively improves its service life. By putting an insulation sleeve 7 made of high-temperature resistant insulation cotton material on the outside of the bearing sleeve 4 and the inner threaded sleeve 5, the insulation effect is effectively improved, and the heat transfer from the inner wheel 14 to the outside is reduced. The first side disc 2 and the second side disc 3, both of which are designed to be sprayed with insulation coating on the outer surface, further improve the insulation effect, avoid excessive heat dissipation, effectively reduce thermal conductivity, reduce heat loss of the workpiece, and improve the use effect of this guide wheel.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
