[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-5 A sheet metal stamping and blanking device includes a punching machine 1, an upper template 2 and a lower die base 3. The upper template 2 is installed on the bottom end of the punching shaft of the punching machine 1, and the lower die base 3 is installed on the workbench of the punching machine 1. A plurality of guide pillars 4 are connected to the lower die base 3. The upper template 2 is slidably connected to the plurality of guide pillars 4. A punching die head 5 is connected to the bottom end of the upper template 2. A punching die hole 6 is opened on the lower die base 3. The punching die hole 6 corresponds to the position of the punching die head 5. A sliding cavity is opened between the two ends of the lower die base 3. 7. An L-shaped support plate 8 is slidably connected in the sliding cavity 7. The L-shaped support plate 8 is located below the stamping die hole 6. An electric push rod 9 is provided on one end of the lower die base 3. The output shaft of the electric push rod 9 is connected to one end of the L-shaped support plate 8. A slot 10 is provided on the other end of the lower die base 3. The slot 10 is located above the sliding cavity 7. Several hinges 11 are provided at the connection between the slot 10 and the sliding cavity 7. The same rotating plate 12 is connected to the several hinges 11. The rotating plate 12 is located in the sliding cavity 7.

[0022] The punching shaft of the punching machine 1 drives the upper template 2 to press down, so that the punching die head 5 punches the metal from the punching die hole 6 into the sliding cavity 7 and falls onto the L-shaped support plate 8. The electric push rod 9 pushes the L-shaped support plate 8 to drive the sheet metal to move toward the notch 10. Through the connection of the hinge 11, the rotating plate 12 rotates outward until the sheet metal moves to the notch 10 and separates from the rotating plate 12. The rotating plate 12 loses the thrust of the sheet metal and automatically falls and rotates a certain angle and contacts the L-shaped support plate 8. At this time, the electric push rod 9 drives the L-shaped support plate 8 to retract, and the position of the hinge 11 restricts the downward rotation of the rotating plate 12, thereby restricting the retraction of the sheet metal part. As a result, after the L-shaped support plate 8 is retracted, the sheet metal part falls from the L-shaped support plate 8 to the slot 10. When the subsequent L-shaped support plate 8 drives the next sheet metal part to extend, the sheet metal part can be completely pushed out of the slot 10, realizing the removal of the sheet metal part without stopping the stamping equipment, thereby ensuring the working efficiency of the sheet metal stamping.

[0023] Specifically, in this embodiment, a buffer spring 13 is sleeved on the outer wall of each guide column 4, and the buffer spring 13 is located between the upper mold plate 2 and the lower mold base 3 to provide a buffering and shock-absorbing effect for the sheet metal part at the moment of stamping and separation from the metal plate.

[0024] Specifically, in this embodiment, two positioning plates 14 are provided on the lower die base 3 . The two positioning plates 14 are respectively located on two symmetrical sides of the punching die hole 6 to provide two-side positioning for the metal plate on the lower die base 3 .

[0025] Specifically, in this embodiment, the inner wall of the stamping die hole 6 is inclined, and the specifications of the opening at one end of the sliding cavity 7 are larger than the specifications of the opening at the top of the lower die base 3, which realizes the stamping separation of the sheet metal part and the metal plate, making the sheet metal part fall more smoothly and preventing the sheet metal part from being blocked in the stamping die hole 6.

[0026] Specifically, in this embodiment, the top height of the wall panel of the L-shaped support plate 8 that is in contact with the bottom wall of the sliding cavity 7 is higher than the bottom height of the rotating plate 12 in the vertical state, so that the L-shaped support plate 8 can push the rotating plate 12 to rotate when moving, avoiding the problem of the rotating plate 12 pushing the sheet metal to move in the opposite direction under the action of the reaction force.

[0027] Specifically, in this embodiment, a plurality of pulleys 15 are rotatably installed in the bottom end of the rotating plate 12 to reduce the friction generated between the L-shaped support plate 8 and the rotating plate 12 during retraction, so that the retraction of the L-shaped support plate 8 is smoother.

[0028] Specifically, in this embodiment, a spring groove 16 is provided on the wall plate of the L-shaped support plate 8 that fits the bottom wall of the sliding cavity 7, and a plurality of compression springs 17 are connected to the spring groove 16. The plurality of compression springs 17 are connected to the same baffle 18, and the top end of the baffle 18 is inclined away from the rotating plate 12. During the process of pushing out the sheet metal, even if it is subjected to the reaction force of the rotating plate 12 and moves in the opposite direction, the setting of the baffle 18 provides a limit for the reverse movement of the sheet metal, and when the L-shaped support plate 8 is retracted, the rotating plate 12 with a fixed relative angle is guided by the inclined surface of the baffle 18, so that the baffle 18 moves into the spring groove 16, and the compression spring 17 is compressed, so that the rotating plate 12 passes through the baffle 18, completing the limitation of the sheet metal and realizing the falling of the sheet metal from the L-shaped support plate 8.

[0029] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
