Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments: like Figure 1-3As shown, an automatic feeding device for a terminal stamping die includes an upper die base plate 1 and two oblique inserts 2 linked on the upper die base plate 1, a lower die base plate 3 and a feeding seat 4 on the lower die base plate 3, and a slider 5 slidably mounted on the feeding seat 4. One end of the slider 5 is rotatably equipped with multiple feeding hooks 7 for driving the movement of the terminal 6. The feeding seat 4 is equipped with a feeding slide plate 8 that covers the slider 5 and is used to support the translation of the terminal 6. A return spring 9 is provided between the other end of the slider 5 and the feeding seat 4. The slider 5 is equipped with a drive shaft 10 that is linked with the two oblique inserts 2. When the upper die base plate 1 performs the opening and closing action, the two oblique inserts 2 move with the upper die base plate 1 and abut against both ends of the drive shaft 10, thus forming a linkage between the drive shaft 10 and the two oblique inserts 2. The driving force of the two oblique inserts 2 causes the drive shaft 10 to drive the slider 5 to slide back and forth in the feeding seat 1.

[0022] like Figure 3 , 4As shown in Figure 6, the feeding slide plate 8 has multiple feeding holes 81 corresponding to multiple feeding hooks 7. Each feeding hook 7 has multiple hook protrusions 71 extending into the feeding holes 81 at one end. Each hook protrusion 71 has a hook inclined surface 72 on the side facing away from the return spring 9. The feeding hooks engage with the circular holes of the terminals via the hook protrusions, and the feeding hooks drive the terminals to move via the hook protrusions, thereby achieving automatic terminal connection and feeding. A cover plate 11 is provided on the feeding slide plate 8, forming a feeding guide cavity 110 between the cover plate 11 and the feeding slide plate 8, allowing the terminals 6 to move. The cover plate prevents debris from falling into the feeding slide plate, effectively improving the reliability of the automatic feeding assembly. A slider 5 has multiple receiving slots 51 at one end to accommodate the multiple feeding hooks 7. A positioning shaft 52 is provided on the slider 5, which passes through the multiple feeding hooks 7, forming a rotatable connection between the multiple feeding hooks 7 and the positioning shaft 52. Multiple feeding hooks are connected to the slider via positioning shafts, facilitating assembly between the hooks and the slider and ensuring flexible movement of the hooks within the receiving groove. Two inclined cutting tools 2 have two driving inclined surfaces 21 on their sides facing both ends of the drive shaft 10. These tools drive the two driving inclined surfaces 21 to abut against both ends of the drive shaft 10. The two inclined cutting tools push the drive shaft through the driving inclined surfaces, ensuring more reliable transmission between the tools and the drive shaft. Two feeding grooves 41 are provided on the feeding seat 4 corresponding to both ends of the drive shaft 10. The drive shaft 10 passes through the two feeding grooves 41, forming a sliding connection between the drive shaft 10 and the feeding seat 4. The drive shaft slides within the feeding grooves of the feeding seat, ensuring reliable drive of the slider. The drive shaft 10 has two bearings 12 exposed at both ends outside the feed seat 4. Two inclined cutting blades 2 drive two inclined surfaces 21 to abut against the two bearings 12 respectively. Rolling bearings 13 that roll along the feed seat 4 are respectively installed on the drive shaft 10. The two inclined cutting blades abut against the bearings on the drive shaft via the inclined surfaces, thus ensuring more reliable transmission between the two inclined cutting blades and the drive shaft. The bearings prevent jamming during transmission between the inclined cutting blades and the drive shaft, improving transmission reliability. By installing rolling bearings on the drive shaft that roll along the feed seat, reliable operation of the drive shaft on the feed seat is ensured.

[0023] like Figure 3-5As shown, the feeding base 4 is provided with a guide groove 42 for accommodating the slider 5, and a guide sliding cavity 421 is formed between the feeding slide plate 8 and the feeding base 4 to allow the slider 5 to slide back and forth. The slider is slidably disposed in the guide groove of the feeding base, thereby ensuring that the slider can reliably move within the feeding base. The feeding base 4 is provided with an end cap 14 covering one end of the guide sliding cavity 421, and the two ends of the return spring 9 respectively abut against the slider 5 and the end cap 14. The end cap is provided on the feeding base, and the return spring is engaged between the end cap and the slider, thereby facilitating the assembly of the return spring and the slider and ensuring that the slider can reliably slide within the feeding base. There are two return springs 9, and two limiting grooves 53 are provided on the slider 5 corresponding to the two return springs 9. One end of the two return springs 9 is engaged in the two limiting grooves 53 respectively, and the other end of the two return springs 9 extends out of the two limiting grooves 53 and abuts against the end cap 14. Two return springs are engaged in the limiting groove of the slider, which facilitates the assembly of the return springs and the slider and ensures that the slider can slide reliably in the feed seat.

[0024] Two slanted cutting tools drive the slider to reciprocate within the feeding seat as the upper mold base plate opens and closes. The slider drives multiple terminals to move on the feeding slide through multiple feeding hooks, thereby realizing continuous automatic feeding of terminals, which helps to improve production efficiency.

[0025] The above description is only one embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model; the scope of protection of the present utility model is defined by the claims in the claims, and all equivalent changes and modifications made in accordance with the utility model are within the scope of protection of the present utility model patent.
