It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete, and to fully convey the concept of these exemplary embodiments to those of ordinary skill in the art.

[0053] like Figures 1 to 3 As shown, the first aspect of the embodiment of the present application proposes an internally heated vacuum rolling mill, comprising: a preparation chamber 110, a rolling mill chamber 120 and a cooling discharge chamber 130 connected in sequence; wherein the rolling mill chamber 120 comprises: a rolling mill chamber body 121, a heater 122 and a rolling mill roller 123, the heater 122 and the rolling mill roller 123 are arranged in the rolling mill chamber body 121, and the rolling mill roller 123 is arranged on the side of the heater 122 away from the preparation chamber 110; wherein the rolling mill roller 123 comprises a roller body 1231, a heating element 1232 and a cooling sleeve, a cavity is formed in the roller body 1231, the heating element 1232 extends into the cavity, and the cooling sleeve is arranged on the end of the roller body 1231.

[0054] The internally heated vacuum rolling mill provided in the embodiment of the present application includes a preparation chamber 110, a rolling mill chamber 120 and a cooling discharge chamber 130 which are connected in sequence, and the rolling mill chamber 120 includes: a rolling mill chamber body 121, a heater 122, a rolling mill roller 123, a heating element 1232 and a correction component 124. Based on this, when the magnetic material is rolled, the magnetic powder is pre-treated to form a block material, and then the block material is transported to the preparation chamber 110, and isolated from the external environment by the preparation chamber 110, and then the entire internally heated vacuum rolling mill system is exhausted and vacuumed, so that The parts to be rolled are in a low-oxygen or oxygen-free state, and then the block materials enter the rolling mill chamber body 121 of the rolling mill chamber 120 through the preparation chamber 110. The materials to be rolled pass through the heater 122, which heats the materials to be rolled, and then are transported to the rolling mill rollers 123. The rolling mill rollers 123 extrude and roll the materials to be rolled to make the materials more compact and improve the product quality. Finally, the products output through the rolling mill rollers 123 can be shaped by the orthopedic component 124 to obtain the final product, and the final product is output through the cooling discharge chamber 130.

[0055] The internally heated vacuum rolling mill provided in the embodiment of the present application, the rolling mill chamber 120 also includes a heating element 1232 arranged in the roller body 1231. Based on this, during the rolling process, the heating element 1232 can preheat the roller body 1231 so that the temperature of the roller body 1231 is close to the rolling temperature. Based on this, the heated workpiece to be rolled can be avoided from contacting the roller surface with a lower temperature, and instead contacts the roller body 1231 with a higher temperature, thereby improving the rolling efficiency.

[0056] The internally heated vacuum rolling mill provided in the embodiment of the present application can heat the rolling mill roller 123 through the inside of the roller body 1231 by arranging a heating element 1232 inside the roller body 1231, so that the roller body 1231 has greater thermal energy. At the same time, there is no need to arrange components outside the rolling mill roller 123, which can simplify the overall structure of the internally heated vacuum rolling mill and improve the heating efficiency of the roller body 1231, thereby improving the rolling efficiency and rolling effect.

[0057] The internally heated vacuum rolling mill provided in the embodiment of the present application takes into account that the rolling mill chamber 120 also needs to be equipped with a driving component for driving the rolling mill roller 123 to rotate. If the temperature of the rolling mill roller 123 is too high, the driving component or the transmission component may be damaged. Therefore, the rolling mill chamber 120 may include a cooling sleeve, and a cooling medium such as liquid water may be supplied in the cooling sleeve. By arranging the cooling sleeve at the end of the rolling mill roller 123, the temperature of the end of the rolling mill roller 123 can be reduced, thereby cooling the driving component and the transmission component of the rolling mill roller 123.

[0058] It can be understood that during the operation of the internally heated vacuum rolling mill, the preheating temperature of the magnetic material is 400-900°C; and the heating temperature of the rolling mill roller 123 is 350-900°C. Based on this, the rolling efficiency of the magnetic material can be improved, especially for the rolling of neodymium-iron-boron (NdFeB) material, which can improve the rolling effect.

The area corresponding to the roller body 1231 and the heating end forms a high-temperature rolling zone 1233, and the area corresponding to the roller body 1231 and the cooling sleeve forms a forced cooling zone 1234. The roller body 1231 forms a high-temperature rolling zone 1233 and a forced cooling zone 1234 between the high-temperature rolling zone 1233 and the forced cooling zone 1234. The natural cooling zone 1235 is formed based on this, which contacts the to-be-rolled product through the high-temperature rolling zone, and can improve the rolling efficiency. The natural cooling zone 1235 is formed on the rolling mill roller 123 between the high-temperature rolling zone 1233 and the forced cooling zone 1234, so that the rolling mill roller 123 can form a temperature transition zone on the roller body 1231, which not only ensures that the rolling mill roller 123 can efficiently roll the to-be-rolled product, but also prevents the driving components of the rolling mill roller 123 from being damaged by high temperature.

At the same time, the processor may also be connected to the heating element 1232 to control the heating power of the heating element 1232 and avoid the temperature of the heating element 1232 being too high.
