[0027] 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.

[0028] Please see Figures 1-6 This utility model provides a technical solution: a stamping die with self-positioning function, comprising:

[0029] Example 1: As Figures 1-5 The present invention provides a technical solution: a stamping die with a self-positioning function, comprising: a lower die holder 1, on which a lower die 2 is fixedly mounted; and a stamping hole 3 is provided on the inner side of the lower die 2; an upper die 4, which is disposed on the upper end of the lower die 2, and a punch 5 is fixedly connected to the bottom of the upper die 4; a workpiece 6, which is disposed between the lower die 2 and the upper die 4; a stamping assembly 7, which is disposed on the upper end of the lower die holder 1; a positioning frame 8, which is fixedly connected to the outer side of the lower die holder 1; a pusher 9, which is slidably connected to the inner side of the positioning frame 8; and a positioning and pushing assembly 10, which is connected to the pusher 9; wherein, the stamping assembly 7 is used to drive the upper die 4 to move up and down to stamp the workpiece 6 on the upper end of the lower die 2; and the positioning and pushing assembly 10 is used to drive the pusher 9 to move left and right to push the workpiece 6 between the lower die 2 and the upper die 4;

[0030] The stamping assembly 7 includes a hydraulic rod 701 and an upper die holder 702. The hydraulic rod 701 is fixedly installed on the upper end of the lower die holder 1, and the output end of the hydraulic rod 701 is fixedly connected to the upper die holder 702. The stamping assembly 7 also includes a sliding rod 703 and a buffer spring 704. The sliding rod 703 is slidably connected to the inner side of the upper die holder 702, and the tail end of the sliding rod 703 is fixedly connected to the upper mold 4. The buffer spring 704 is connected between the upper mold 4 and the upper die holder 702.

[0031] When this structure needs to stamp the workpiece 6, the workpiece 6 is first placed between the lower mold 2 and the upper mold 4. Then, the hydraulic rod 701 is driven. The output end of the hydraulic rod 701 drives the upper mold frame 702 to move downward. The downward movement of the upper mold frame 702 will also drive the upper mold 4 to move downward, so that the punch 5 punches and drills the workpiece 6 at the upper end of the lower mold 2. When the upper mold 4 moves downward, it will be subjected to the counter-impact force of the lower mold 2. The buffer spring 704 between the upper mold frame 702 and the upper mold 4 will buffer this impact force, thus not only protecting the upper mold 4 and the lower mold 2, but also improving the quality of the workpiece 6 being drilled.

[0032] Example 2: Figures 1-2 , Figure 6 The present invention provides a technical solution: a stamping die with a self-positioning function, which discloses that: the positioning and pushing assembly 10 includes a discharge box 1001, which is fixedly installed on the upper end of the positioning frame 8, and the discharge port of the discharge box 1001 communicates with the inner sliding groove of the positioning frame 8; the positioning and pushing assembly 10 also includes a drive motor 1002 and a gear 1003, the drive motor 1002 is fixedly installed on the outside of the positioning frame 8, and the output end of the drive motor 1002 is fixedly connected to the gear 1003. 3. The gear 1003 is viewed from above as a half-tooth structure; the positioning and pushing assembly 10 also includes a rack 1004, which is fixedly connected to the outside of the push head 9 and meshes with the outer gear 1003; the positioning and pushing assembly 10 also includes a guide rod 1005 and a telescopic spring 1006, which is fixedly connected to the outside of the rack 1004 and slidably connected to the inside of the positioning frame 8, and the end of the guide rod 1005 is connected to the positioning frame 8 with the telescopic spring 1006;

[0033] When material needs to be loaded, this structure operates the drive motor 1002, which drives the gear 1003 to rotate. When the tooth surface of the gear 1003 meshes with the rack 1004, it drives the rack 1004 forward and stretches the telescopic spring 1006, causing the push head 9 to slide forward along the inner side of the positioning frame 8, pushing the workpiece 6 inside the positioning frame 8 forward and placing it between the upper mold 4 and the lower mold 2. When the tooth surface of the gear 1003 separates from the rack 1004, the rack... 1004 will be reset by the elastic force of the telescopic spring 1006, so that the push head 9 slides backward along the inner side of the positioning frame 8. At this time, the bottom of the discharge box 1001 is empty, and the workpiece 6 at the bottom of the discharge box 1001 will fall into the inner slide groove of the positioning frame 8. Through the reciprocating operation of the above structure, the push head 9 will accurately push the workpiece 6 between the upper mold 4 and the lower mold 2 at regular intervals for drilling. Moreover, it can prevent the workpiece 6 from shifting position during feeding, thereby achieving the effect of positioning feeding.
