Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-3 A crossbeam stamping die workpiece unloading mechanism includes a support plate 1 and a lower die 2 installed on the top of the support plate 1. A fixed groove 3 is provided on the top of the support plate 1. Three movable top plates 4 are provided inside the fixed groove 3. A movable push plate 5 is provided above the support plate 1 and on the rear side of the lower die 2.

[0021] Furthermore, a controller is fixedly connected to the left side of the top of the support plate 1 .

[0022] It also includes a servo motor 6, which is installed on the back of the inner wall of the fixed groove 3. The surface of the output shaft of the servo motor 6 is fixedly connected to a rotating protrusion 7. The left and right sides of the inner wall of the fixed groove 3 are provided with a slide groove 8 that is connected to each other. The top and bottom of the inner wall of the slide groove 8 are fixedly connected by a slide rod 9. The surface of the slide rod 9 is slidably connected to a slider 10. The surface of the slide rod 9 is sleeved with a buffer spring 11. The opposite sides of the two sliders 10 are fixedly connected to a moving block 12. The opposite sides of the two moving blocks 12 are fixedly connected to a moving plate 13. The groove at the bottom of the moving plate 13 is rotatably connected to a ball 14 that is adapted to the rotating protrusion 7. The end of the ball 14 close to the rotating protrusion 7 is in rolling contact with the rotating protrusion 7. The top of the movable plate 13 is fixedly connected to a pressure sensor 15, and the top of the pressure sensor 15 is fixedly connected to a connecting plate 16. The top plate 4 is installed on the top of the connecting plate 16. A through opening 17 is provided at the top of the lower mold 2 and at a position corresponding to the top plate 4. The top of the top plate 4 passes through the fixed groove 3 and the through opening 17 from bottom to top and extends to the inside of the through opening 17. The top of the support plate 1 is fixedly connected to a fixed plate 18 at the rear side of the push plate 5. The front of the fixed plate 18 is fixedly connected to a cylinder 19, and the front end of the cylinder 19 is fixedly connected to the back of the push plate 5.

[0023] Furthermore, as shown in the figure, the buffer spring 11 at this time has the force to squeeze the slider 10 to move downward, so that the ball 14 can always maintain a rolling contact state with the rotating protrusion 7.

[0024] A support frame is fixedly connected to the right side of the top of the support plate 1, and an upper mold 20 that is compatible with the lower mold 2 is fixedly connected to the support frame through a hydraulic cylinder. A collection shell 21 is set in the groove at the top of the front of the support plate 1. The collection shell 21 can be removed by pulling the collection shell 21 forward.

[0025] Furthermore, the servo motor 6, pressure sensor 15, cylinder 19 and hydraulic cylinder are electrically connected to the controller respectively, and the control circuit can be implemented by simple programming by technicians in this field. It is common knowledge in this field and will not be elaborated on here.

[0026] Through the mutual cooperation of the fixed groove 3, the top plate 4, the push plate 5, the servo motor 6, the rotating protrusion 7, the slide groove 8, the slide rod 9, the slider 10, the buffer spring 11, the moving block 12, the moving plate 13, the ball 14, the pressure sensor 15, the connecting plate 16, the through port 17, the fixed plate 18, the cylinder 19 and the collecting shell 21, the automatic unloading of the workpiece after the stamping is completed is facilitated, and the need for manual unloading is avoided, thereby reducing labor and improving safety.

[0027] During use, the crossbeam workpiece is placed on the lower die 2, and then the upper die 20 is driven downward by the hydraulic cylinder to punch the workpiece on the lower die 2. After the punching is completed, the upper die 20 moves upward to return to its original position, and then the servo motor 6 is started by the controller. The servo motor 6 drives the rotating protrusion 7 to rotate 90 degrees clockwise through the output shaft, so that the protruding end of the rotating protrusion 7 contacts the ball 14, so that the ball 14 drives the moving plate 13 and the moving block 12 to move upward. The moving block 12 presses the buffer spring 11 upward through the slider 10 to move, and the moving plate 13 drives the top plate 4 to move upward, so that the top plate 4 lifts the workpiece on the lower die 2. At the same time, the pressure sensor 15 senses the pressure value. Then the signal is transmitted to the controller, and the controller starts the cylinder 19. The cylinder 19 drives the push plate 5 to move forward, pushing the workpiece into the collection shell 21 for collection. When the workpiece and the top plate 4 are separated, the pressure sensor 15 cannot sense the pressure value, and then the signal is transmitted to the controller, and the controller starts the servo motor 6. The servo motor 6 drives the rotating protrusion 7 to rotate 90 degrees clockwise again, so that the protruding end of the rotating protrusion 7 and the ball 14 are separated. Through the restoring elastic force of the buffer spring 11, the buffer spring 11 drives the slider 10 and the movable plate 13 to move downward, so that the movable plate 13 drives the top plate 4 to move downward, so that the top plate 4 moves to the inside of the through opening 17 and returns to its original position.

[0028] To sum up: the crossbeam stamping die workpiece unloading mechanism solves the problems raised in the above-mentioned background technology through the mutual cooperation of the fixed groove 3, the top plate 4, the push plate 5, the servo motor 6, the rotating protrusion 7, the slide groove 8, the slide rod 9, the slider 10, the buffer spring 11, the moving block 12, the moving plate 13, the ball 14, the pressure sensor 15, the connecting plate 16, the through port 17, the fixed plate 18, the cylinder 19 and the collection shell 21.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
