[0038] The sintering machine using the above technical solution is equipped with an electric lifting module 3 for electrically driving the energy-concentrating ring 4 to move up and down to adjust its height. This makes operation convenient and can improve operational efficiency.

The PLC controller is fixedly installed inside the chassis 1, and the control output terminal of the PLC controller is electrically connected to the electrical control terminal of the motor 303. The two proximity sensors 306 are used to detect the position of the slider 305 on the lead screw 304, so as to cooperate with the PLC controller to control the motor 303 to automatically rotate forward and reverse, thereby improving the automation level of the electric lifting module 3 and preventing the slider 305 from moving excessively to the upper or lower end of the lead screw 304.

[0041] Specifically, in this embodiment, the energy-concentrating ring 4 includes a housing fixedly installed at the end of the slider 305 away from the linear guide rail 302, and an electric heating coil and a temperature sensor fixedly installed inside the housing. The electrical control terminal of the electric heating coil is electrically connected to the control output terminal of the PLC controller, and the signal output terminal of the temperature sensor is electrically connected to the signal input terminal of the PLC controller. The electric heating coil is used to heat and sinter the tool holder 6 to be sintered, and the temperature sensor is used to detect the heating temperature of the electric heating coil and transmit the detected temperature information to the PLC controller in real time so that the PLC controller can control the electric heating coil to work automatically.

[0045] Specifically, in this embodiment, a power switch 103 is fixedly installed on the side of the chassis 1. The power switch 103 is connected in series with the power socket 105. The power switch 103 is used to control the sintering machine to turn on and off.

[0046] Specifically, in this embodiment, a sound hole 106 is provided at the rear of the chassis 1, and a speaker corresponding to the sound hole 106 is fixedly installed inside the chassis 1. The speaker is electrically connected to the PLC controller. The speaker is used to alarm in case of failure and to provide voice prompts on the working status of the sintering machine.

[0047] Specifically, in this embodiment, in order to dissipate heat from the components inside the chassis 1, heat dissipation holes 104 are provided on both side walls of the chassis 1. A cooling fan and a temperature control switch can also be installed inside the chassis 1. The cooling fan is connected in series with the power socket 105, and the temperature control switch is connected in series between the cooling fan and the power socket 105.

[0053] 3. Lifting adjustment: The touch screen 101 or the lifting switch 102 sends a signal to the PLC controller to control the motor 303 to rotate forward and backward, thereby driving the lead screw 304 to rotate, causing the slider 305 to move up and down along the linear guide rail 302, thereby adjusting the height of the energy-concentrating ring 4 to a suitable position to surround the tool holder 6.

[0054] 4. Heating and Sintering: When the energy-concentrating ring 4 reaches the designated position, the PLC controller controls the electric heating coil to start working, heating and sintering the tool holder 6. The temperature sensor monitors the heating temperature in real time and feeds the data back to the PLC controller to ensure that the sintering process is carried out within the set temperature range.

[0055] 5. End and Removal: After sintering is completed, the motor 303 is reversed by controlling the touch display screen 101 or the lifting switch 102 to raise the energy-concentrating ring 4, and then the sintered tool holder 6 is removed.

[0056] Beneficial effects:

[0057] 1. Easy to operate: The up and down movement of the energy-concentrating ring 4 is adjusted by the electric lifting module 3, which is simple and quick to operate and improves work efficiency.

[0058] 4. High degree of automation: The sintering process is automated by using PLC controllers, proximity sensors 306, temperature sensors and other components, which reduces manual intervention and improves sintering accuracy and stability.

[0059] 4.

[0060] 5. Comprehensive Functionality: The touch screen 101 provides a user-friendly interface for setting operating parameters and viewing equipment status; the speaker is used for fault alarms and voice prompts, enhancing the ease of use and reliability of the equipment.

[0061] 6. Excellent heat dissipation: The heat dissipation holes 104 on both sides of the chassis 1, as well as the optional cooling fan and temperature control switch, effectively reduce the internal temperature of the chassis and extend the service life of the equipment.
