However, it is obvious to those skilled in the art that the technical solutions provided by the present application can be implemented without one or more of these details.
[0059] It is to be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments consistent with the present disclosure. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.
[0060] Example embodiments consistent with the present disclosure will now be described in more detail with reference to the drawings. These Example embodiments may, however, be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the concepts to those skilled in the art.
[0061] As shown in Figures 1 to 4 A first aspect of the embodiments of the present application proposes a rolling device 100, comprising: a rolling mill chamber body 110; a heater 120, the heater 120 being arranged in the rolling mill chamber body 110; two rolling mill rolls 130, a rolling gap being formed between the two rolling mill rolls 130, the rolling mill rolls 130 being arranged on one side of the heater 120; and a heating member 140, the heating member 140 being configured to provide heat energy for the rolling mill rolls 130.
[0062] The rolling device 100 provided by the embodiments of the present application comprises the rolling mill chamber body 110, the heater 120, the two rolling mill rolls 130, and the heating member 140. Based on this, when the rolling device 100 provided by the embodiments of the present application is used to roll a magnetic material, the material to be rolled enters the rolling device 100, passes through the heater 120, and is heated by the heater 120. Then, the material to be rolled is conveyed to the rolling mill rolls 130, and is extruded and rolled by the rolling mill rolls 130, so that the material is more compact, and the product quality is improved. Before the material to be rolled is rolled by the rolling mill rolls 130, the material to be rolled can be preheated by the heating member 140, or the rolling mill rolls 130 can be heated by the heating member 140 during rolling. Based on this, the temperature of the rolling mill rolls 130 approaches the rolling temperature, so that the material to be rolled, which has been completely heated, contacts the rolling mill rolls 130 with a high temperature, rather than the rolling surface with a low temperature, and the rolling efficiency is improved.
[0063] In one possible implementation, the length of the rolling mill roll is greater than or equal to 500 mm.
[0064] In the technical solution, further considering that the rolling device 100 can be equipped with a driving component for driving the rolling mill roller 130 to rotate, if the temperature of the rolling mill roller 130 is too high, the driving component or the transmission component can be damaged, by setting the length of the rolling mill roller to be greater than or equal to 500 mm, a certain distance can be formed between the end of the rolling mill roller and the heating member 140, which is beneficial to the cooling of the end of the rolling mill roller, and the driving component or the transmission component can be prevented from being damaged by the rolling mill roller with too high temperature.
[0065] In an available implementation, the rolling device 100 further comprises a cooling sleeve, the cooling sleeve is sleeved on the end of the rolling mill roller.
[0066] In the technical solution, in order to further reduce the temperature of the end of the rolling mill roller, the cooling sleeve can be sleeved on the end of the rolling mill roller, and a cooling medium can be supplied in the cooling sleeve to cool the rolling mill roller. It can be understood that the cooling medium can be water.
[0067] As shown in Figures 1 to 2 In an available implementation, the rolling mill roller 130 is a hollow structure, and the heating member 140 is arranged in the rolling mill roller 130.
[0068] In the technical solution, a heating member 140 arrangement is provided, the rolling mill roller 130 can be a hollow structure, and the heating member 140 is arranged in the rolling mill roller 130. Based on this, during the rolling process, the heating member 140 can preheat the rolling mill roller 130, so that the temperature of the rolling mill roller 130 approaches the rolling temperature, and thus the completed heating workpiece can be prevented from being in contact with the roller surface with a lower temperature, but in contact with the rolling mill roller 130 with a higher temperature, thereby improving the rolling efficiency. By arranging the heating member 140 in the rolling mill roller 130, the rolling mill roller 130 can be heated from the inside of the rolling mill roller 130, so that the rolling mill roller 130 has more heat energy, and at the same time, there is no need to arrange components outside the rolling mill roller 130, which can simplify the structure of the whole rolling device, improve the heating efficiency of the rolling mill roller 130, and further improve the rolling efficiency and rolling effect.
[0069] As shown in Figures 3 to 4 In an available implementation, the heating member 140 is sleeved on the outside of the two rolling mill rollers 130; wherein, in the case that the heating member 140 is sleeved on the outside of the two rolling mill rollers 130, the outside of the heating member 140 is provided with a heat insulation sleeve 1110.
[0070] In the technical solution, another arrangement of the heating member 140 is provided, and the heating member 140 can also be sleeved outside the two rolling mill rollers 130, and in this case, a heat insulation sleeve 1110 can be provided outside the heating member 140. Based on this, during the rolling process, the heating member 140 can preheat the rolling mill rollers 130, so that the temperature of the rolling mill rollers 130 approaches the rolling temperature, and based on this, the completed heating workpiece can avoid being in contact with the roller surface with a lower temperature, but is in contact with the rolling mill roller 130 with a higher temperature, thereby improving the rolling efficiency. By sleeving the heating member 140 outside the rolling mill roller 130, heat energy can be provided for the rolling mill roller 130 without changing the structure of the rolling mill roller 130, thereby facilitating the preparation of the rolling equipment 100 and reducing the cost. By arranging the heat insulation sleeve 1110, the heat dissipation amount can be reduced, and more heat energy can be concentrated on the rolling mill roller.
[0071] It can be understood that, during the working process of the rolling equipment 100, the preheating temperature of the magnetic material is 400-900°C; and the heating temperature of the rolling mill roller 130 is 350-900°C, based on which the rolling efficiency of the magnetic material can be improved, especially for the rolling of the neodymium-iron-boron material (NdFeB), and the rolling effect can be improved.
[0072] In some examples, the heating temperature of the heating member 140 is 300-950°C.

[0074] In the technical solution, the structure of the rolling equipment 100 is further provided, and the rolling equipment 100 can further include the feeding assembly 150, and the feeding assembly 150 can include the feeding channel 151, the first operating glove 160 and the pushing member 152. Based on this, after the block-shaped workpiece to be rolled is conveyed to the rolling equipment 100, the operator can use a handheld tool (such as an extended pair of pliers) and the first operating glove 160 to adjust the workpiece to be rolled, and then the pushing member 152 can convey the workpiece to be rolled to the heater 120 by using the feeding channel 151, so as to complete the rolling and heating of the workpiece to be rolled.
[0075] In this technical solution, the feed channel 151 and heater 120 are covered by the insulation layer 170, which can reduce the leakage of heat energy.

The straightening component 190 may include a transmission component 191, a cylinder 192, and a straightening component 193. Based on this, during the operation, the product rolled by the mill rolls 130 is conveyed to the cooling discharge chamber 220 through the transmission component 191. During this process, the cylinder 192 can be opened so that the straightening component 193 comes into contact with the rolled product to shape the rolled product and reduce the probability of product warping and deformation. After that, it is conveyed to the cooling discharge chamber 220 through the transmission component 191.
[0079] Understandably, cylinder 192 may include hydraulic cylinders and pneumatic cylinders, and orthotic element 193 may be made of ceramic material.
[0080] like Figures 1 to 4 As shown, in one feasible embodiment, the heater 120 is an induction heater 120, and a channel is formed inside the induction heater 120, which leads to the rolling mill roll 130.
