Detailed Implementation
[0022] 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. Example
[0023] like Figure 1-5 As shown in the figure, an embodiment of the present invention provides a stamping die for automotive seat sheet metal, including a worktable 1. A buffer support assembly 2 is provided on the upper surface of the worktable 1. A sheet metal stamping assembly 3 is provided above the buffer support assembly 2. Sheet metal part limiting clamping assemblies 4 are provided on both sides of the buffer support assembly 2. The sheet metal part limiting clamping assemblies 4 are used to limit the position of the sheet metal part to be processed.
[0024] like Figure 2 and Figure 3As shown, the sheet metal part limiting clamping assembly 4 includes two sets of slide grooves 41 opened on the upper end face of the worktable 1 and two gears 42 rotatably arranged on the lower end face of the worktable 1. Each set of slide grooves 41 consists of two gears, and the two gears 42 are respectively located below the two sets of slide grooves 41. A slider 43 is slidably arranged in each slide groove 41. A toothed plate 44 is fixedly arranged on the lower end face of the slider 43. The toothed plate 44 on the slider 43 in each set of slide grooves 41 meshes with the two gears 42 respectively. A connecting plate 45 is fixedly installed on the upper end face of each slider 43, and a clamping plate 46 is fixedly installed on the upper end face of each connecting plate 45. A U-shaped frame 47 is provided between the two gears 42. The U-shaped frame 47 is fixedly connected to the worktable 1. A servo motor 48 is fixedly installed on the lower end face of the U-shaped frame 47. The output end of the servo motor 48 passes through the U-shaped frame 47. A transmission component 49 is fixedly installed on each of the two gears 42. Both transmission components 49 are connected to the output end of the servo motor 48 through a belt.
[0025] The sheet metal part limiting clamping component 4 can clamp the metal parts placed on the sheet metal stamping component 3. This not only restricts the position of the metal parts, thus preventing them from shifting during the stamping process, but also corrects any shifts in the metal parts' placement. This effectively improves the quality of the stamping process. In addition, the sheet metal part limiting clamping component 4 can be used for stamped metal parts of different widths and sizes.
[0026] like Figure 2 and Figure 3 As shown, the sheet metal stamping assembly 3 includes a fixed frame 31 fixedly mounted on the upper surface of the worktable 1. A stamping cylinder 32 is fixedly mounted on the top inner side of the fixed frame 31. An upper stamping module 33 is fixedly mounted on the output end of the stamping cylinder 32. A lower stamping module 34 is mounted below the upper stamping module 33 and is mounted on the buffer support assembly 2. Both the lower stamping module 34 and the upper stamping module 33 are located in the middle of the four clamping plates 46. The stamping cylinder 32 provides kinetic energy for the movement of the upper stamping module 33. The cooperation between the upper stamping module 33 and the lower stamping module 34 can process the metal part into the required shape.
[0027] like Figure 5As shown, the buffer support assembly 2 includes a support block 21 fixedly mounted on the upper surface of the workbench 1 and a guide block 24 fixedly mounted on the lower surface of the lower stamping module 34. The upper surface of the support block 21 has a receiving groove 22, and the guide block 24 on the lower surface of the lower stamping module 34 is inserted into the receiving groove 22 on the upper surface of the support block 21. Multiple helical springs 23 are fixedly mounted at the bottom inner side of the receiving groove 22, and one end of each helical spring 23 is fixedly connected to the guide block 24 inserted into the receiving groove 22. A limit block 25 is fixedly mounted at the bottom inner side of the receiving groove 22.
[0028] The buffer support component 2 is configured to buffer the downward movement of the lower stamping module 34. When the metal part on the lower stamping module 34 is finished being processed, the lower stamping module 34 can push the metal part on it upward. The upward movement of the metal part will generate friction between it and the clamping plate 46, which can loosen the clamping force of the clamping plate 46 on the stamped metal part, so that the metal part can be easily removed from the clamping of the clamping plate 46.
[0029] like Figure 4 As shown, a limiting rod 5 is fixedly installed on the side wall of the clamping plate 46 opposite to the support block 21. The cross-section of the limiting rod 5 is L-shaped. Four limiting grooves 6 are opened on the support block 21. One end of the four limiting rods 5 on the clamping plate 46 is respectively inserted into the four limiting grooves 6 on the support block 21.
[0030] The stability of the clamping plate 46 moving along the slide groove 41 can be improved by setting the limiting rod 5 and the limiting groove 6.
[0031] The working principle of this practical application is as follows:
[0032] First, the metal part to be processed is placed on the upper surface of the lower stamping module 34. Then, the servo motor 48 is started. The servo motor 48 drives two gears 42 to rotate via a belt. The rotation of the gears 42 causes the gear plate 44 to move the metal part on the upper surface of the lower stamping module 34. The gear plate 44 drives the clamping plate 46 on it to move. When the clamping plate 46 on the gear plate 44 contacts the metal part on the upper surface of the lower stamping module 34, the clamping plate 46 will push the metal part to move towards the center. If placed... When the metal part on the upper surface of the lower stamping module 34 is placed at an angle, the angled metal part is gradually corrected under the clamping of the clamping plate 46. When the clamping plate 46 clamps the metal part on the upper surface of the lower stamping module 34, the stamping cylinder 32 is activated. The stamping cylinder 32 drives the upper stamping module 33 to stamp the metal part on the upper surface of the lower stamping module 34. The force on the lower stamping module 34 will move it towards the bottom of the receiving groove 22 through the guide block 24. During the downward movement of the lower stamping module 34, the guide block 24 guides the lower stamping module 34 to move towards the bottom of the receiving groove 22. Block 24 will squeeze the helical spring 23 in the receiving groove 22. The helical spring 23 is compressed by force. When the lower end face of the guide block 24 is abutted against the upper end face of the limit block 25, the lower stamping module 34 stops moving downward. The upper stamping module 33 stamps the metal part on the upper end face of the lower stamping module 34. When the metal part stamping is finished, the upper stamping module 33 is restored to its original position by the stamping cylinder 32. During the process of the upper stamping module 33 returning to its original position, the lower stamping module 34 moves upward and returns to its original position under the action of the elastic potential energy of the helical spring 23. During the upward movement, the lower stamping module 34 rubs against the clamping plate 46, which can loosen the clamping force of the clamping plate 46 on the stamped metal part, so that the metal part can be easily removed from the clamping plate 46. Repeat the above to perform repetitive processing on the metal part. If the metal part with a different width is changed, the servo motor 48 is started again to adjust the distance between the clamping plates 46 to adapt to the metal parts with different widths.
[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
