[0023] (III) Beneficial effects

[0024] Compared with the prior art, the present invention provides an intelligent forming machine tool for metal processing machinery manufacturing, which has the following beneficial effects:

[0025] 1. When the present invention is in use, the workpiece is fixed on the workbench, and the workbench and the workpiece are moved to the center of the circular track by a linear motor. Then, the CNC host controls the spindle motor to drive the transmission shaft to make the turning head work. By starting the first reduction motor to drive the propulsion mechanism, the rotating turning head is brought into contact with the workpiece. At this time, the workpiece can be processed. At the same time, the positioning component can adjust the propulsion mechanism to tilt the turning head to meet the processing requirements. When the transmission shaft is working to process the workpiece, an anti-eccentric load mechanism installed in the frame can actively offset the eccentric load force on the output shaft of the spindle motor 21 to protect the shaft system components. During the processing, for irregular workpieces, the transverse movement component can be adjusted in the vertical and axial directions by the adjustment mechanism. When the adjustment mechanism is working, the fourth reduction motor drives the side plate to swing the transverse movement component and the linear motor. When the linear motor swings, it drives the workbench to tilt the workpiece. At the same time, starting the electric push rod can directly push the transverse movement component to move the linear motor and the workbench, and adjust the distance between the workpiece and the turning head, so that the machine tool can process workpieces of different sizes.

[0026] 2. The propulsion mechanism provided in the present invention, when in use, starts the first reduction motor to drive the worm to rotate the worm wheel, the rotation of the worm wheel drives the lead screw to move the slider, the movement of the slider drives the guide seat to move the spindle motor and the housing, at this time the spindle motor and the anti-eccentric load mechanism can be adjusted to make the turning head contact the workpiece for turning work, when the inclination angle of the propulsion mechanism needs to be changed, the stepper motor is started to drive the bevel gear to rotate, and the bevel gear rolls on the surface of the semi-bevel gear ring when rotating, at this time the frame drives the spindle motor and the turning head to tilt to achieve the first angle adjustment, so that the turning head can process the workpiece at different angles, and in addition, the third reduction motor is started The driving gear is driven to rotate the gear ring, and the rotation of the gear ring drives the two mounting seats to do circular motion. When the mounting seat moves, it can drive the arc guide rail to do circular motion with the center line of the gear ring as the axis. At this time, the second angle adjustment can be achieved. The second reduction motor is started to drive the bracket to rotate. When the bracket rotates, it drives the arc guide rail to swing with an axis perpendicular to the center line of the gear ring. In this way, the third angle adjustment can be achieved. After three angle adjustments, the actual movement path of the turning head is hemispherical, and after being pushed by the propulsion mechanism, the diameter range of the hemispherical path can be adjusted according to the processing requirements, so that the machine tool can process workpieces with special-shaped curved surface structures.

[0027] 3. The present invention is provided with an anti-eccentric load mechanism. When in use, the electromagnet works to generate magnetic force to push the strong magnet. The strong magnet is forced to squeeze the pressure sensor to make the rectangular block forced. The rectangular block is forced to drive the arc plate to make the roller squeeze the annular protrusion. At this time, the difference in values ​​detected by multiple pressure sensors circumferentially distributed around the annular protrusion is small or the same. When the turning head is subjected to force, an eccentric load force is generated on one side of it. At this time, the value of the pressure sensor on the side with uneven force changes. After the CNC host receives the signal of pressure change, the power of the electromagnet on the corresponding side is controlled to change according to the size of the pressure change. When the electromagnet power When it changes, the magnetic repulsion between it and the strong magnet also changes, which eventually increases the force acting on one side of the annular protrusion of the roller until it is close to or the same as the off-load force. At this time, the off-load force on the turning head and the drive shaft can be offset by the force between the electromagnet and the strong magnet, and when the drive shaft is driven by the spindle motor to rotate at high speed, the fan blades fixed on the drive shaft rotate to push air in from the air inlet and out through the guide pipe, so that the force-adding component during operation can be cooled, and the exhausted airflow directly acts near the turning head, so that the contact part between the turning head and the workpiece can be assisted by air cooling.

When the turning head is stressed, an eccentric load force is generated on one side of it. At this time, the value of the pressure sensor 40 on the side with uneven stress changes. After the CNC host receives the signal of pressure change, the power of the electromagnet 42 on the corresponding side is controlled to change according to the size of the pressure change. When the power of the electromagnet 42 When it changes, the magnetic repulsion generated between it and the strong magnet 41 also changes, which eventually increases the force of the roller 39 acting on one side of the annular protrusion 43 until it is close to or the same as the off-load force. At this time, the off-load force on the turning head and the transmission shaft 32 can be offset by the force between the electromagnet 42 and the strong magnet 41, and when the transmission shaft 32 is driven by the spindle motor 21 to rotate at high speed, the fan blades 33 fixed on the transmission shaft 32 rotate to push air in from the air inlet and discharge through the guide tube 48, so that the force-adding component during operation can be cooled, and the exhausted airflow directly acts near the turning head, so as to assist in air cooling the contact part between the turning head and the workpiece.
