[0044] In one embodiment, the heating element 500 is an electro-infrared heating mechanism. It should be noted that an electro-infrared heating mechanism is a device that uses electrical energy to generate infrared radiation, directly heating objects or space through infrared rays. Its working principle is to convert electrical energy into heat energy through heating elements such as resistance wires, thereby emitting infrared radiation. Infrared radiation has strong penetrating power and heating effect, and can directly act on the surface of an object, causing it to absorb energy and convert it into heat energy, thus achieving the heating purpose.

The two cooling components 600 are respectively mounted on the machine base 100 and can respectively cool both ends of the axle housing 2000. It can be understood that after the heated wheel edge 3000 is pressed onto the end of the axle housing 2000, the corresponding cooling component 600 cools the connection between the two. It should be noted that the cooling component 600 can cool the workpiece to 50°C to 60°C.

[0046] In one embodiment, the cooling element 600 is a vortex tube exhaust cooling mechanism. It should be noted that the vortex tube exhaust cooling mechanism utilizes compressed air to generate a high-speed rotating airflow within the vortex tube, thereby achieving separation of hot and cold airflows. Its working principle involves introducing compressed air with a certain pressure into the vortex tube's swirling chamber through a nozzle. The airflow rotates at extremely high speed within the swirling chamber, forming two airflows, inner and outer. The outer airflow, due to its greater kinetic energy and higher temperature, is discharged from the hot end; the inner airflow, due to energy loss and a lower temperature, is discharged from the cold end.

[0047] Reference Figure 3 As shown, the wheel edge pressing device 1000 of one embodiment of the present invention further includes a third driving member 700, which is mounted on the base 100. The placement platform 200 is slidably connected to the base 100. The third driving member 700 can drive the placement platform 200 to slide along the width direction of the base 100, thereby moving the axle housing 2000 to the next work station for the next processing step. In one embodiment, the base 100 is provided with a guide rail arranged along the width direction of the base 100, and the placement platform 200 is slidably connected to the base 100 through the guide rail.
