7. A method for assembling a box using a multi-head moving press according to claim 6, characterized in that, Includes the following steps: Step 1: The conveyor line moves the tooling plate and its loaded workpiece until the tooling plate contacts the roller (59), and pushes the baffle (57) to rotate on the baffle fixing frame (58) through the roller (59), so that the baffle fixing frame (58) and the roller (59) tilt up to block the tooling plate. The other end of the baffle (57) presses down on the buffer device, thereby buffering the impact force brought by the movement of the tooling plate. When the sensor unit senses that the tooling plate has reached the designated position, it starts the lower cylinder (51) to drive the lifting plate (52) to move vertically upward under the limiting action of the limit guide rod (53) and the guide rod movable hole (54). The positioning pin (55) on the lifting plate (52) is inserted into the positioning hole of the tooling plate to lift the tooling plate away from the conveyor chain. Step 2: Start the drive motor (65) to drive the screw (64) to rotate through the transmission assembly (66). With the cooperation of the pressure head slide rail (61) and the pressure head slider (62), the screw (64) drives the pressure head slide plate (63) to move horizontally. The pressure head slide plate (63) drives the upper oil cylinder (68) to move in the oil cylinder movable groove (69) until the sensor unit senses that the pressure head slide plate (63) has moved to the set position, so that the pressure head (610) can be aligned with the workpiece to be processed. Start the upper oil cylinder (68) to drive the pressure head (610) to press down vertically to complete the pressing work of the box part. Step 3: Start the drive cylinder (714). With the cooperation of the turntable slide rail (711) and the turntable slider (712), the drive cylinder (714) drives the turntable slide plate (713) to move towards the lower end of the pressure head (610). With the cooperation of the cylinder stroke stop block (715) and the turntable slide plate positioning block (717), the position of the turntable (721) is positioned so that the pressure head sleeve slot (723) is aligned with the pressure head (610). The shock absorber (716) buffers and dampens the movement of the turntable slide plate (713). Step 4: Start the turntable drive motor (722) to drive the turntable (721) to rotate. The turntable (721) rotates 90 degrees each time, so that a set of pressure head sleeve slots (723) and pressure head sleeves (724) are aligned with the pressure head (610). When a set of empty pressure head sleeve slots (723) are aligned with the pressure head (610), the output end of the locking block cylinder (726) extends, driving the pressure head sleeve locking block (725) away from the pressure head sleeve slots (723). The pressure head (610) presses down vertically to place the unused pressure head sleeves (724) into the pressure head sleeve slots (723). The output end of the locking block cylinder (726) drives the pressure head sleeve locking block (725) to perform a reset movement to lock the pressure head sleeves (724). Then the pressure head (610) resets, and the pressure head sleeves (724) are blocked by the pressure head sleeve locking block (725) and remain in the pressure head sleeves (724). Step 5: Drive the pressure head sleeve locking block (725) away from the pressure head sleeve slot (723) again through the locking block cylinder (726), start the turntable drive motor (722) to drive the turntable (721) to rotate so that the pressure head sleeve slot (723) and pressure head sleeve (724) to be used are aligned with the pressure head (610). The pressure head (610) is pressed vertically down and inserted into the insertion hole of the pressure head sleeve (724). The pressure head sleeve (724) is connected to the pressure head (610) through the set strong magnetic attraction block. After the pressure head (610) is equipped with the pressure head sleeve (724), it is reset. Then the drive cylinder (714) drives the turntable slide plate (713) to reset, completing the quick replacement of the pressure head sleeve. Step 6: After the workpiece is processed, the output end of the blocking cylinder (56) moves vertically downward under the cooperation of the blocking cylinder guide rod (510), so that the baffle (57) and roller (59) can no longer block the movement of the tooling plate; the lower oil cylinder (51) drives the lifting plate (52) to reset and release the tooling plate on the conveyor line.
