[0012] The utility model is further described below in conjunction with the accompanying drawings.

[0013] like Figure 1 , Figure 2 As shown, the utility model includes four fixtures 1, a test piece 2, four support rods 3, a circular support plate 4, a water tank 5, a water tank water inlet pipe 14, a water tank water outlet pipe 13, a flame spray gun 6, a rotating drive platform 7, a servo motor 8, a quenching air pipe 9, a controller and a base. The base includes a rotating platform mounting column 10, a flame spray gun mounting column 11, and a test platform 12. The rotating platform mounting column 10 and the flame spray gun mounting column 11 are installed on the test platform 12, and the flame spray gun mounting column 11 is located behind the rotating platform mounting column 10.

[0014] The rotating platform mounting column 10 is provided with a servo motor 8, one end of the circular support plate 4 is fixedly connected to the output shaft of the servo motor 8, the circular support plate 4 is coaxial with the output shaft of the servo motor 8, and the circular support plate 4 can rotate under the drive of the servo motor 8. The fixture 1 is used to clamp the test piece 2, and the fixture 1 is connected to the side of the circular support plate 4 through the support rod 3. The four fixtures are located on the same circumference and are evenly arranged on the circumference. The water tank 5 is arranged directly below the fixture 1. The flame spray gun 6 is fixed on the flame spray gun mounting column 11 of the base, and is arranged on the circumference where the test piece 2 is located, and can heat the test piece 2. The outlet of the quenching air pipe 9 is arranged on the circumference where the test piece 2 is located, and can cool the test piece on a fixture. The flame spray gun 6, the servo motor 8 and the quenching air pipe 9 are respectively connected to the controller. The controller controls the spraying time and temperature of the flame spray gun 6, controls the rotation angle of the servo motor 8, and controls the temperature of the cooling air of the quenching air pipe 9.

[0015] The flame spray gun 6 can control the flame spraying time and temperature. The quenching air pipe 9 can be provided with two outlets, both of which are arranged on the circumference of the test piece 2. The phase angles of the two outlets of the quenching air pipe 9 and the flame spray gun 6 on the circumference of the test piece 2 are both 90 degrees.

[0016] The water tank 5 is provided with a water inlet pipe 13 and a water outlet pipe 14. The water inlet pipe 13 is connected to tap water, and the water outlet pipe 14 is connected to the wastewater treatment tank through a water pipe. A flowing water flow can be selected, and the water temperature is kept at room temperature, so that the test piece after water cooling quickly reaches room temperature.

[0017] When the test piece is cooled by a combination of air cooling and water cooling, when the fixture 1 holding the test piece rotates to the heating station corresponding to the flame spray gun, after heating for a specified time, the controller controls the rotating drive platform to drive the circular support plate 4 to rotate 90 degrees clockwise, so that the fixture 1 rotates to the air cooling station for air cooling. At the same time, the original fixture 1 is rotated to the water cooling station after air cooling for thorough water cooling. And so on, each test piece is subjected to cyclic heating and gradual air cooling and water cooling experiments.

[0018] When only water cooling is used for the test piece, when the fixture 1 holding the test piece rotates to the heating station and is heated for a specified time, the controller controls the rotating drive platform to drive the circular support plate 4 to rotate 180 degrees clockwise, so that the test piece is rotated to the water cooling station for cooling. At the same time, the upper fixture 1 is rotated to the heating station after water cooling to continue to be heated. And so on, a cyclic heating and water cooling experiment is performed on each test piece.
