[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In this embodiment of the utility model, please refer to Figures 1 to 4 A stamping production line die buffer and protection device includes a base plate 1, the base plate 1 being connected to the bottom end of an electric telescopic rod 4, the top end of the electric telescopic rod 4 being connected to a top plate 5, the top plate 5 being connected to an upper die 6, and the base plate 1 being slidably connected to a lower die 9, the lower die 9 being provided with a pressure groove, and further includes: Controller 27 is connected to base plate 1; The translation mechanism is connected to the top plate 5 at one end and to the lower mold 9 at the other end, and is used to drive the lower mold 9 to move. The buffer mechanism is connected at one end to the upper mold 6 and at the other end to the lower mold 9, and is used to buffer the punching pressure. The ejector mechanism is connected to the lower mold 9 and intercepted by the buffer mechanism, and is used to eject the material after stamping.

[0019] As one embodiment of this utility model, please refer to Figure 1 , Figure 3 and Figure 4 The translation mechanism includes: Through groove 2 is formed on base plate 1; Slide 3 is provided on the base plate 1; The slider 7 is located in the groove 3 and is slidably engaged with it. The slider 7 is connected to the lower mold 9. Spring 8 is located in the groove 3, with one end connected to the slider 7 and the other end connected to the base plate 1; A trapezoidal plate 10 is connected to the top plate 5. One side of the bottom of the trapezoidal plate 10 has a slanted structure. The trapezoidal plate 10 is located at the top of the through groove 2. The folding rod 11 is connected to the lower mold 9 and abuts against the trapezoidal plate 10.

[0020] In the initial state, spring 8 is in the stored and relaxed state, the lower mold 9 is not directly below the upper mold 6, and the lower mold 9 is located in front of the base plate 1, which makes it convenient for workers to place materials on the lower mold 9; As the electric telescopic rod 4 drives the top plate 5 to move downward, it drives the upper mold 6 and trapezoidal plate 10 to move downward synchronously. When the inclined structure of the trapezoidal plate 10 moves downward to abut against the folding rod 11, the top plate 5 continues to move downward. At this time, the trapezoidal plate 10 squeezes the folding rod 11, causing the folding rod 11 to drive the lower mold 9 to slide in the slide groove 3. The spring 8 deforms. When the straight edge structure of the trapezoidal plate 10 abuts against the folding rod 11, the lower mold 9 can no longer move and is directly below the upper mold 6. The upper mold 6 continues to move downward to press the material. After stamping is completed, the upper die 6 moves upward. When the inclined structure on the trapezoidal plate 10 moves to abut against the folding rod 11, the upper die 6 has already moved to disengage from the lower die 9. At this time, under the reaction force of the spring 8, the lower die 9 moves back to the initial state, making it easier for the workers to remove the stamped material. Because the lower mold 9 and the upper mold 6 are not on the same vertical plane when loading and unloading materials, the safety of the workers is ensured.

[0021] As one embodiment of this utility model, please refer to Figure 1 and Figure 2 The buffer mechanism includes: Impact rod 12 is connected to upper mold 6; The positioning cylinder 14 is connected to the lower mold 9 and is located at the bottom of the impact rod 12; Cavity 17 is located inside the lower mold 9 and is connected to the inside of the positioning cylinder 14; Air chamber 18 is connected to the interior of cavity 17 and to the outside. A one-way valve is provided inside air chamber 18. Piston 15 slides against the inner wall of positioning cylinder 14; Piston 2 19 slides and abuts against cavity 1 17; Spring 20 is connected at both ends to the two sets of pistons 2 19.

[0022] During the stamping process, the impact rod 12 moves downward and inserts into the positioning cylinder 14, pushing the piston 15 to move downward. The movement of the piston 15 will cause the gas in the positioning cylinder 14 to enter the cavity 17, causing the piston 29 to slide in the cavity 17. The spring 20 is compressed, which buffers the stamping pressure. The gas between the two sets of pistons 29 enters the ejector mechanism. When the stamping is finished and the upper die 6 moves upward, the air pressure in cavity 17 decreases, and external gas enters cavity 17 through air chamber 18, causing piston 15 and piston 29 to return to their initial positions. Spring 20 returns to its original state, and one-way valve 1 ensures that air can only enter cavity 17 through air chamber 18 in one direction.

[0023] As one embodiment of this utility model, please refer to Figure 1 and Figure 2 The top-feeding mechanism includes: Air chamber 21 is connected to the interior of cavity 17, and a one-way valve 2 is provided inside air chamber 21; Cavity 22 is located inside the lower mold 9 and is connected to the interior of air cavity 21; Air cavity 3 23 is connected to the top of cavity 2 22 and is also connected to the outside. Air chamber 24 is connected at its bottom to the bottom of cavity 22 and at its top to the pressure groove. An electromagnetic valve is provided inside air chamber 24. Piston 3 25 slides against the inner wall of cavity 2 22; Spring 3 26 is connected at one end to piston 3 25 and at the other end to cavity 2 22; The sensing component, with one end connected to piston 15 and the other end connected to impact rod 12, is used to control the solenoid valve. The sensing component includes: The sensing element 13 is connected to the impact rod 12; The second sensing element 16 is connected to the first piston 15.

[0024] During the stamping process, the impact rod 12 moves downward. When the first sensing element 13 and the second sensing element 16 come into contact, a signal is triggered, and the controller 27 controls the solenoid valve to close. The gas between the two sets of pistons 29 enters the cavity 22 through the air chamber 21. At this time, the piston 3 25 moves upward, and the spring 3 26 undergoes elastic deformation, which buffers the stamping pressure for a second time. The air at the top of the piston 3 25 flows to the outside through the air chamber 3 23. After the stamping is completed, the impact rod 12 moves upward. When the first sensing element 13 and the second sensing element 16 are separated, the controller 27 controls the solenoid valve to open. Under the reaction force of the third spring 26, the air at the bottom of the third piston 25 flows into the pressure groove through the fourth air chamber 24. The gas lifts the material, and the lifting force and the material are in flexible contact to avoid damage to the material. The one-way valve 2 ensures that the gas in cavity 17 can only enter cavity 22 in one direction.

[0025] The working principle of this utility model is as follows: In the initial state, the spring 8 is in a stored and relaxed state, the lower mold 9 is not directly below the upper mold 6, and the lower mold 9 is located in front of the base plate 1, which makes it convenient for workers to place materials on the lower mold 9. As the electric telescopic rod 4 drives the top plate 5 to move downward, it drives the upper mold 6 and trapezoidal plate 10 to move downward synchronously. When the inclined structure of the trapezoidal plate 10 moves downward to abut against the folding rod 11, the top plate 5 continues to move downward. At this time, the trapezoidal plate 10 squeezes the folding rod 11, causing the folding rod 11 to drive the lower mold 9 to slide in the slide groove 3. The spring 8 deforms. When the straight edge structure of the trapezoidal plate 10 abuts against the folding rod 11, the lower mold 9 can no longer move and is directly below the upper mold 6. The upper mold 6 continues to move downward to press the material. During the stamping process, the impact rod 12 moves downward. When the first sensor 13 and the second sensor 16 come into contact, a signal is triggered, and the controller 27 controls the solenoid valve to close. The impact rod 12 moves downward and inserts into the positioning cylinder 14, pushing the first piston 15 to move downward. The movement of the first piston 15 will cause the gas in the positioning cylinder 14 to enter the first cavity 17, causing the second piston 19 to slide in the first cavity 17. The second spring 20 is compressed, buffering the stamping pressure. The gas between the two sets of second pistons 19 enters the second cavity 22 through the second air chamber 21. At this time, the third piston 25 moves upward, and the third spring 26 undergoes elastic deformation, buffering the stamping pressure a second time. The air at the top of the third piston 25 flows to the outside through the third air chamber 23. After stamping is completed, the upper die 6 moves upward. When the inclined structure on the trapezoidal plate 10 moves to abut against the folding rod 11, the upper die 6 has already moved to disengage from the lower die 9. At this time, under the reaction force of the spring 8, the lower die 9 moves back to the initial state, making it easier for the workers to remove the stamped material. When the impact rod 12 moves upward, and the sensing element 13 and sensing element 2 16 disengage, the controller 27 controls the solenoid valve to open. Under the reaction force of the spring 3 26, the air at the bottom of the piston 3 25 flows into the pressure groove through the air chamber 4 24. The gas lifts the material, and the lifting force and the material make flexible contact to avoid damage to the material.
