[0002] Automotive sheet metal parts refer to the parts that make up the metal shell and some internal structures of the car. Due to the high requirements for pressure-bearing strength, most of them are processed and produced using hot forming forging machines. Before hot forming forging, it is generally necessary to use a heating device to heat the workpiece to the required forming temperature, and then use a manipulator to move it to the mold of the hot forming forging machine with a heat preservation furnace for forging.

The forming accuracy is low and the forming effect is poor. After the forging of the workpiece is completed, it is necessary to operate the opening and closing device to open the holding furnace to a larger space, and then operate the manipulator to take out the workpiece that has been formed.

After starting work, the staff starts the heater 4, and the heater 4 generates heat to keep the temperature in the insulation furnace 3 at a suitable working temperature for molding. Then the staff operates the manipulator to place the workpiece heated to the molding temperature on the top of the discharge rack 5. After the workpiece is placed, the staff controls the telescopic rod of the electric push rod 131 to retract. The retraction of the telescopic rod of the electric push rod 131 drives the push rack 132 to move horizontally.

After one side of the workpiece is tightly fitted with the forming groove of the mold 7, the staff controls the telescopic rod of the electric push rod 131 to extend.

When the workpiece is formed, the support plate 8 and the ball 10 will be pressed into the mold 1 7, and the support spring 9 will be compressed. After the workpiece is completely formed, the magnetic frame 155 contacts the top of the rack 156, and the magnetic frame 155 adsorbs the rack 156, then the staff controls the telescopic rod of the hydraulic push rod 11 to retract, and the contraction of the telescopic rod of the entire hydraulic push rod 11 drives the mold 2 12 to move upward, and the mold 2 12 moves upward to break contact with the formed workpiece, and drives the magnetic frame 155 to move upward, and the supporting spring 9 will rebound and drive the supporting plate 8 and the ball 10 to move upward, and the supporting plate 8 and the ball 10 move upward to lift the formed workpiece, and under the action of the magnetic attraction force of the magnetic frame 155 being greater than the torsion of the torsion spring 152, the magnetic frame 155 moves upward and drives the rack 156 to move upward, and the rack 156 moves upward and drives the gear 3 157 to rotate, and the gear 3 157 rotates and drives the rotating shaft 151 to rotate, the torsion spring 152 is twisted, and the rotating shaft 151 rotates and drives the limit plate 153 to rotate,The two groups of limiting plates 153 are in contact with the two sides of the workpiece respectively. When the slot on the rotating shaft 151 rotates to vertically upward, the rotating shaft 151 no longer abuts the locking column 154 and the weight 1541. Under the action of gravity, the locking column 154 and the weight 1541 will move downward, and the lower end of the locking column 154 enters the slot of the rotating shaft 151. The locking column 154 clamps the rotating shaft 151, and then clamps the limiting plate 153 to limit the workpiece, reducing the risk of the workpiece falling off prematurely during discharge and causing jamming. When the rack 156 continues to move upward, the mold 17 abuts against the protrusion on the rack 156, so that the rack 156 cannot continue to move upward, and the magnetic frame 155 continues to move upward and disengages from the top of the rack 156; Initially, the locking mechanism of the servo self-locking motor 141 locks the output shaft of the servo self-locking motor 141, and then clamps the mold 1 7 through the sprocket 1 142, the chain 144 and the sprocket 2 143. After the mold 2 12 is reset to the initial position, the staff starts the servo self-locking motor 141, and the output shaft of the servo self-locking motor 141 rotates to drive the sprocket 1 142 to rotate. The rotation of the sprocket 142 drives the sprocket 2 143 to rotate through the chain 144. The rotation of the sprocket 2 143 drives the mold 1 7 to rotate. The rotation of the mold 1 7 drives the gear 1 146, the supporting plate 8, the supporting spring 9, the ball 10, the rotating shaft 151, the torsion spring 152, and the limit plate 153, locking column 154, weight 1541, rack 156, gear three 157 and workpiece rotate, the workpiece rotates into the cavity of the discharge frame 6, when the rotation angle of the workpiece is greater than 90 degrees, the weight 1541 will drive the locking column 154 to gradually disengage from the slot of the rotating shaft 151 under the action of gravity, when the workpiece is about to face vertically downward, the weight 1541 drives the locking column 154 to completely disengage from the slot of the rotating shaft 151, the torsion spring 152 will rebound and drive the rotating shaft 151 to rotate in the opposite direction, the rotating shaft 151 rotates in the opposite direction to drive the limit plate 153 and gear three 157 to rotate in the opposite direction, the limit plate 153 rotates in the opposite direction to disengage from the workpiece, and under the gravity Under the action of, the workpiece will fall toward the opening at the bottom of the discharge frame 6. When the molding groove of the mold 1 7 rotates to vertically downward, the mold 1 7 isolates the inner cavity of the insulation furnace 3 from the inner cavity of the discharge frame 6 to reduce the heat loss in the insulation furnace 3. The gear 1 146 is meshed with the gear 2 148 and drives the gear 2 148 to rotate. The rotation of the gear 2 148 drives the turntable 147 to rotate. The rotation of the turntable 147 drives the transmission column 149 to rotate. The transmission column 149 rotates through the slot frame 1410 to drive the closing frame 1411 to move horizontally. The closing frame 1411 no longer covers the opening at the bottom of the discharge frame 6. The molded workpiece falls out from the opening at the bottom of the discharge frame 6. The transmission column 149 continues to rotate and drives the closing frame 1411 to move in the opposite direction through the slot frame 1410. The closing frame 1411 covers the opening at the bottom of the discharge frame 6 again. Through the above operation, the heat loss of the insulation furnace 3 when the workpiece is discharged can be reduced, and the time required for preheating the insulation furnace 3 during subsequent processing can be reduced, thereby improving the overall production efficiency. Gear 1 146 continues to rotate and disengages from gear 2 148. After the mold 1 7 is reset to the initial state, the staff stops the servo self-locking motor 141 and repeats the above operation to process the next workpiece. After all the workpieces are processed, the staff turns off the heater 4 and stops heating the insulation furnace 3.
