[0022] 1. In this utility model, by setting an adjustment component and a sintering module, during use, the hydraulic press is started, which drives the connecting plate, thereby driving the mounting cover. The mounting cover drives the motor, thereby driving the mounting shaft and the placement plate, moving the placement plate out of the sintering module. The hard alloy to be sintered is placed in the placement plate. The hydraulic press is then started again to retract the placement plate into the sintering module, and the mounting cover is placed on top of the sintering module. While the output shaft of the hydraulic press is driven, the output shaft of the hydraulic press is cleaned by cleaning rubber to prevent impurities from adhering to the output shaft, reducing the amount of cleaning work required. At this time, the sintering module is started, and the sintering process is completed. The sintering module sintersects the cemented carbide, then the motor is started. The motor drives the mounting shaft and the placement plate, which in turn drives the cemented carbide to rotate. This rotation of the cemented carbide within the sintering module ensures uniform heating. This design utilizes a hydraulic system to automatically open and close the mounting cover, and facilitates the removal and insertion of the placement plate into the sintering module. A cleaning rubber strip is used to clean the output shaft of the hydraulic system, preventing impurities from adhering to it and reducing cleaning workload. The rotation of the cemented carbide via the sintering module and the motor further ensures uniform heating of the cemented carbide.

At this time, the transmission is started and the air supply pipe of the cooler is connected to the cooling pipe, so that the cold air is delivered to the protective shell through the cooling pipe. Then, the transmission drives the cooling fan, and the cooling fan and the delivered cold air dissipate heat on the motor, so as to avoid the motor temperature from being too high and affecting its service life. Through this design, the cooling fan and the delivered cold air are used to dissipate heat on the motor, so as to avoid the motor temperature from being too high and affecting its service life.

[0032] The specific implementation method is as follows: In use, the hydraulic pump 32 is started, which drives the connecting plate 34, thereby driving the mounting cover 35. The mounting cover 35 drives the motor 39, which in turn drives the mounting shaft 36 and the placement plate 37, moving the placement plate 37 out of the sintering module 1. The hard alloy to be sintered is placed in the placement plate 37. The hydraulic pump 32 is then started again, causing the placement plate 37 to retract into the sintering module 1, and the mounting cover 35 to cover the top of the sintering module 1. While the output shaft of the hydraulic pump 32 is driven, the output shaft of the hydraulic pump 32 is cleaned by the cleaning rubber 33 to prevent impurities from adhering to the output shaft of the hydraulic pump 32 and reduce the amount of cleaning work required. At this time, the sintering module 1 is started, and the hard alloy is sintered through the sintering module 1.

[0034] The specific implementation method is as follows: After long-term use, the temperature of the motor 39 may rise. At this time, the transmission 42 is started and the air supply pipe of the cooler is connected to the cooling pipe 44, so that the cold air is delivered to the protective shell 5 through the cooling pipe 44.

The mounting cover 35 drives the motor 39, which in turn drives the mounting shaft 36 and the placement plate 37, moving the placement plate 37 out of the sintering module 1. The hard alloy to be sintered is then placed in the placement plate 37. The hydraulic actuator 32 is then activated again, causing the placement plate 37 to retract into the sintering module 1, and the mounting cover 35 to cover the top of the sintering module 1. Simultaneously, the output shaft of the hydraulic actuator 32 is cleaned by the cleaning rubber 33 to prevent impurities from adhering to the output shaft, reducing the amount of cleaning work required.

Then, the motor 39 is started, which drives the mounting shaft 36 and the placement plate 37. The placement plate 37 drives the cemented carbide, causing it to rotate. By rotating the cemented carbide and connecting it with the sintering module 1, the cemented carbide can be heated evenly. After prolonged use, the temperature of the motor 39 may rise. At this time, the transmission 42 is started, and the air supply pipe of the cooler is connected to the cooler pipe 44, so that the cold air is delivered to the protective shell 5 through the cooler pipe 44. Then, the transmission 42 drives the cooling fan 43, which, together with the delivered cold air, dissipates heat from the motor 39, preventing the motor 39 from overheating and affecting its service life.
