The lifting rod 5-1 of the lifting cylinder 5 passes through the horizontal frame plate 3-1 and is connected to the base 6-2 at the bottom of the workpiece frame plate 6. The bottom area of the base 6-2 is larger than the bottom area of the workpiece frame plate 6, and its setting serves to facilitate the connection with the lifting rod 5-1. An electric heating component is arranged inside the infrared heater 4, and the electric heating component includes a carbon fiber heating resistance wire. An opening for the workpiece frame plate 6 to pass through is provided at the bottom of the infrared heater 4. A control switch 3-2 is arranged on the vertical frame 3 near the workbench 1, and the control switch 3-2 is electrically connected to the lifting cylinder 5 and the infrared heater 4;
