When the molybdenum plate target blank heating operation needs to be carried out, the formed molybdenum plate target blank is placed on the conveyor belt 64. At this time, manually open the sealing door 5. At this time, the single-chip microcomputer 8 can be adjusted. The stepping motor 65 operates, and the output shaft of the stepping motor 65 rotates, thereby driving the first conveying roller 62 to rotate, and then driving the second conveying roller 63 to rotate synchronously through the conveyor belt 64, thereby giving the molybdenum plate target blank a leftward traveling force;

[0024] Molybdenum plate receiving mechanism 2: It includes a mounting plate 21, a chute 22, a roller mounting seat 23, a conduction roller 24, a displacement frame 25, an L-shaped docking frame 26 and a molybdenum plate receiving plate 27.

[0025] The working principle of a molybdenum plate target blank heating furnace provided by the present utility model is as follows: When molybdenum plate target blank heating operation is required, the formed molybdenum plate target blank is placed on the conveyor belt 64. At this time, manually open the sealing door 5, and then the single-chip microcomputer 8 can be adjusted. The stepping motor 65 operates, and the output shaft of the stepping motor 65 rotates, thereby driving the first conveying roller 62 to rotate. Then, through the conveyor belt 64, the second conveying roller 63 is driven to rotate synchronously, thereby giving the molybdenum plate target blank a forward force to the left. Then, through the conveying force of the conduction roller 24, after the molybdenum plate target blank is conveyed to the designated position by the conduction roller 24, the external oil pump can be adjusted, and the telescopic end of the telescopic cylinder 9 contracts, thereby driving the mounting plate 21 to move upward, and then driving the three molybdenum plate receiving plates 27 to move upward until the three molybdenum plate receiving plates 27 support the molybdenum plate target blank from the left, middle, and right three directions. At this time, the single-chip microcomputer 8 can be adjusted, and the electromagnetic heating wire operates. The electromagnetic heating wire heats the temperature inside the furnace body 1. At the same time, the single-chip microcomputer 8 is adjusted, and the two temperature sensors 4 operate simultaneously. The two temperature sensors 4 measure the temperatures on the left and right sides inside the furnace body 1 in real time. The electromagnetic heating wire heats the temperature inside the furnace body 1 to the designated temperature. The electromagnetic heating wire then heats the molybdenum plate target blank. After the heating is completed, the sealing door 5 can be opened with tools, and the molybdenum plate target blank can be clamped with clamping tools until most of the lower surface of the molybdenum plate target blank is placed on the conveyor belt 64. At this time, the single-chip microcomputer 8 can be adjusted, and the conveyor belt 64 conveys the molybdenum plate target blank out of the heating furnace.
