[0028] The trigger assembly 3 is arranged on the side of the heating element 12, and the trigger assembly 3 comprises a heat-conducting plate 31 arranged on the side of the heating element 12. The side of the heat-conducting plate 31 is fixedly connected with a double-plate metal 32. The bottom of the double-plate metal 32 is provided with a first sleeve 21. The inner wall of the first sleeve 21 is provided with a first groove 23. The bottom of the first sleeve 21 is fixedly connected with the top of a supporting plate 22. The top of the supporting plate 22 is provided with a sliding groove 24. One end of a supporting rod 25 extends into the inner cavity of the sliding groove 24. The one end of the supporting rod 25 is in sliding connection with the inner cavity of the sliding groove 24. The outer surface of a fixing rod 27 is sleeved with a second sleeve 26. The inner cavity of the second sleeve 26 is provided with a second groove 28. The outer surface of a third sleeve 212 is provided with a fourth groove 213. One end of a second sliding rod 214 extends into the inner cavity of the fourth groove 213. The one end of the second sliding rod 214 is in sliding connection with the inner cavity of the fourth groove 213. The temperature reflecting plate 215 is arranged on the side of the heat insulation plate 11, so that the scattered waste heat can be reflected back to the middle part of the inner cavity of the resistance furnace body 1 during the processing, the heat concentration effect is effectively improved, and the steel ball tempering work is assisted. The output end of the push rod arranged at the bottom of the double-plate metal 32 is in sliding connection with the inner cavity of the first sleeve 21. The first groove 23 arranged on the inner wall of the first sleeve 21 can make the first sleeve 21 rotate clockwise when the output end of the push rod moves downward. The supporting plate 22 and the sliding groove 24 are matched, so that the supporting rod 25 can be driven to move to the middle part of the supporting plate 22 when the first sleeve 21 rotates clockwise, and then the fixing rod 27 can be driven to move along the inner cavity of the second sleeve 26. The second groove 28 arranged on the inner wall of the second sleeve 26 can make the second sleeve 26 rotate clockwise when the fixing rod 27 moves.

The third sleeve 212 and the fourth groove 213 are matched, so that the temperature reflecting plate 215 can be driven to reciprocate by the second sliding rod 214, and then the effect of adjusting the reflecting angle can be achieved.

[0029] Further, as shown in Figure 3 The side of the double-plate metal 32 is fixedly connected with a fastening spring body 33. The bottom of the double-plate metal 32 is fixedly connected with a mounting frame 34. The heat-conducting plate 31 arranged on the side of the heating element 12 can transmit heat to the double-plate metal 32 during the tempering process. The double-plate metal 32 can expand when the temperature increases to a certain degree, and then the push rod arranged at the bottom of the double-plate metal 32 can be driven to move.

[0030] When tempering the steel ball, the resistance furnace body 1 will inevitably shake, which will affect the intermittent transmission efficiency of the wheel disc 29 and the first sliding rod 211, as shown in the prior art. Figure 4 As shown in the prior art, the side of the wheel disc 29 is provided with a third groove 210, and the inner cavity of the third groove 210 is slidably connected with the first sliding rod 211. The side of the first sliding rod 211 is fixedly connected with the third sleeve 212. By designing the third groove 210 as a heart shape, it can be ensured that the first sliding rod 211 always maintains one end in contact with the inner cavity of the third groove 210 during movement, avoiding the position of the first sliding rod 211 from shifting when the resistance furnace body 1 shakes, which will cause intermittent transmission failure.

[0031] Working principle:

[0032] As shown in the prior art, Figures 1-4 As shown in the prior art,

[0033] In use: first, place the steel ball to be tempered in the inner cavity of the resistance furnace body 1. After closing the resistance furnace body 1, start the heating element 12 to heat the inner cavity of the resistance furnace body 1. During heating, the residual heat scattered in the four corners of the inner cavity of the resistance furnace body 1 contacts the side of the temperature reflecting plate 215 and is then reflected back to the middle of the resistance furnace body 1, thereby improving the heating efficiency and assisting in tempering work. When the temperature reaches a certain level, the high temperature is transmitted to the double-piece metal 32 through the heat-conducting plate 31, and the double-piece metal 32 expands, thereby triggering the push rod arranged at the bottom of the double-piece metal 32. The output end of the push rod moves downward, thereby driving the support plate 22 through the first sleeve 21 to move, and then driving the support rod 25 to move to the middle of the support plate 22. When the support rod 25 moves, it is cooperated with the second groove 28 through the fixing rod 27, thereby driving the wheel disc 29 to rotate clockwise through the second sleeve 26. The first sliding rod 211 is driven to move intermittently through the cooperation of the wheel disc 29 and the third groove 210, thereby achieving the effect of gradually flattening the temperature reflecting plate 215 through the second sliding rod 214. Avoiding the sudden change of the temperature reflecting plate 215, which will affect the heat balance of the inner cavity of the resistance furnace body 1. When the temperature reflecting plate 215 moves to a certain position, the temperature reflecting plate 215 is completely flattened, thereby maintaining the temperature uniformity of the inner cavity of the resistance furnace body 1.

[0034] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in other forms, and any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields with equivalent changes, but any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application without departing from the technical scheme of the present application still falls within the protection scope of the present application.
