[0011] A method for using an intelligent box-type heating furnace for heat treatment includes the following steps: Step 1: Place the workpiece on the surface of the placement plate and heat it inside the heating furnace body. When performing heat treatment, the output end of the first servo motor drives the top plate to rotate, so that the top plate drives the second limiting plate to rotate through the second support column, so that the second limiting plate drives the first limiting plate to rotate through the first support column, thereby driving the workpiece on the placement plate to rotate, so as to heat the workpiece and make the workpiece evenly heated. The temperature inside the heating furnace body is detected by a temperature sensor. The intelligent control terminal adjusts the temperature inside the heating furnace body according to the temperature data inside the heating furnace body and the heat treatment process of the workpiece. Step 2: After the workpiece is heat-treated, the output end of the second servo motor drives the cover plate to rotate, so that the sealing groove is opened. Then, the output end of the third servo motor drives the first threaded rod to rotate, so that the first threaded rod drives the moving block to move, and the moving block drives the fixed frame to move to the side of the sealing groove. Then, the telescopic end of the second electric telescopic rod on the right side pushes the second fixing plate to move, so that the plug box is inserted into the slot. Then, the output end of the fifth servo motor drives the ball screw to rotate, so that the ball screw drives the driving block to move, and the driving block drives one end of the second clamping column to move into the column groove. At the same time, the output ends of the sixth servo motors on the left and right sides both drive the threaded columns to rotate, so that the threaded columns drive the push blocks to move, and the push blocks push the support plate, the third electric telescopic rod and the guide plate to move through the removal groove to the outside of the placement table. Then, the telescopic end of the third electric telescopic rod pushes the guide plate to move upward, so that the upper surface of the guide plate is on the same horizontal line as the upper surface of the placement table. Then, the telescopic end of the first electric telescopic rod drives the limit disc to move upward, so that the limit disc drives the limit block, the fixed rod, the moving plate, the connecting rod and the driving plate to move upward, so that the moving plate and the driving plate drive the bottom end of the first clamping column to move out of the clamping groove. Then, the telescopic end of the second electric telescopic rod drives the second fixing plate, the placement plate and the processed workpiece to move above the placement table; Step 3: The telescopic end of the second electric telescopic rod on the left side pushes the second fixing plate and the placement plate to move above the guide plate. The two placement plates move to the surfaces of the second limit plate and the first limit plate respectively through the guide plate, so that both sides of the placement plate are located inside the connecting rod. Then, the output end of the fifth servo motor on the left side drives the ball screw to rotate, so that the ball screw drives one end of the second clamping column to move out of the column groove. Then, the telescopic end of the second electric telescopic rod drives the second fixing plate and the plug box to move back, so that one end of the plug box moves out of the slot, and the second fixing plate is moved above the placement table. Then, the telescopic end of the third electric telescopic rod drives the guide plate to move downward. Then, the output end of the sixth servo motor drives the threaded column to rotate back, so that the threaded column drives the push block to drive the support plate, the third electric telescopic rod and the guide plate to move through the removal groove to the inside of the placement table. Then, the telescopic end of the first electric telescopic rod pushes the limit disc to move downward, so that the limit disc drives the fixed rod, the moving plate, the connecting rod and the driving plate to move downward through the limit block, so that the moving plate and the driving plate drive the bottom end of the corresponding first clamping column to be inserted into the clamping groove to limit the position of the placement plate. Then, the fixed frame, the lower placement mechanism and the upper placement mechanism move to the rear of the heating furnace body. Then, the output end of the second servo motor drives the cover plate to rotate back, so that the cover plate closes the sealing groove; Step 4: When it is necessary to remove the workpiece on the placement plate placed on the surface of the placement table, first remove the workpiece on the lower placement mechanism, and then the output end of the fourth servo motor drives the second threaded rod to rotate, so that the second threaded rod drives the slider to move downward, thereby limiting the position of the upper placement mechanism. Then remove the workpiece on the surface of the upper placement mechanism. Then the output end of the fourth servo motor drives the second threaded rod to rotate in place, so that the second threaded rod drives the slider to drive the placement table to move upward, so that the upper placement mechanism moves upward. When placing new workpieces on the placement plates on the left-side upper placement mechanism and the lower placement mechanism, operate according to the above process.
