[0025] 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.

[0026] Please see Figures 1 to 8 This utility model provides a technical solution: a metal wire bending and forming mechanism, including a bottom mold 1, a stamping mechanism 2, and an ejection mechanism 3. The bottom mold 1 has a wire hole 11 and a discharge hole 12, which penetrates the upper and lower ends of the bottom mold 1. The discharge hole 12 is a strip-shaped hole, and its length direction is consistent with the length direction of the wire hole 11. The wire hole 11 and the discharge hole 12 are connected. The wire 100 is inserted into the discharge hole 12 after being inserted into the wire hole 11, until the top end of the wire is tightly against the other side of the discharge hole 12. The upper end of the wire hole 11 and the discharge hole 12 are connected. The inserted wire is located inside the upper end of the discharge hole 12, waiting for cutting and stamping. A cutting base 4 is movably provided at the upper end of the discharge hole 12. The cutting base 4 is used to support the wire after it is inserted.

[0027] The stamping mechanism 2 includes a pressure head 21 and a stamping plate 22. The stamping plate 22 is located at the lower end of the pressure head 21 and is symmetrically arranged on both sides of the bottom end of the pressure head 21. The width between the two stamping plates 22 is slightly larger than the width of the cutting base 4. The difference in width is generally set to 3mm to 7mm depending on the application. When the two stamping plates 22 are pressed down, they cooperate with the cutting base 4 to stamp the wire into shape. The stamping plate 22 is movably connected to the discharge hole 12, and the pressure head 21 drives the stamping plate 22 to move up and down.

[0028] A cutter 5 is provided inside the discharge hole 12, and the cutter 5 is located inside the wire hole 11. The cutter 5 is aligned with the wire hole, and when the stamping plate 22 is pressed down, the cutter 5 quickly cuts the wire.

[0029] The ejection mechanism 3 is movably connected to the discharge hole 12 to eject the stamped wire from the bottom die 1.

[0030] In an embodiment of this utility model, the ejection mechanism 3 includes an ejection moving mold 31 and a top plate 32, with the top plate 32 located at the bottom end of the ejection moving mold 31.

[0031] In this embodiment of the invention, the top plate 32 passes through the pressure head 21 and is movably positioned between the two stamping plates 22. The stamped wire may become stuck in the discharge hole, and the top plate 32 will eject the stuck wire from the bottom mold 1.

[0032] In this embodiment of the invention, the cutting base 4 includes a slider 41. The upper end of the bottom mold 1 is provided with a groove 13, which is connected to the discharge hole 12. The slider 41 is movably disposed within the groove 13. At the start of the cutting operation, the slider 41 is located within the groove 13, with one end of the slider 41 positioned at the discharge hole 12. When the wire is inserted, one end of the wire is located at the upper end of the slider 41. The width of the slider 41 is the inner width of the wire to be cut. During cutting, the stamping plate 22 presses down, pressing down the wire on both sides of the slider 41, where one end of the wire is cut by the cutter, resulting in a U-shaped staple. After cutting is complete, the cutting base 4 moves outward, and the cut wire falls from the discharge hole 12.

[0033] In this embodiment of the invention, a lower pressure block 23 is provided on one side of the pressure head 21. The lower pressure block 23 has a lower inclined surface 24. The slider 41 has a pressure-bearing block 42, and the pressure-bearing block 42 has an upper inclined surface 43. The lower inclined surface 24 and the upper inclined surface 43 are in sliding contact. After the stamping plate 22 completes the stamping, the pressure head 21 continues to descend, and the lower inclined surface 24 contacts the upper inclined surface 43. The pressure-bearing block 42 is pushed outward by the lower inclined surface 24, causing the wire to fall off.

[0034] In an embodiment of this utility model, the pressure head 21 is provided with an upward-opening blind hole 25, and the bottom end of the ejector moving mold 31 is provided with a connecting post 33, which is movably connected to the blind hole 25.

[0035] In an embodiment of this utility model, a spring 34 is sleeved on the connecting post 33.

[0036] In this embodiment of the invention, a housing 6 is also included, with the stamping mechanism 2 and the ejection mechanism 3 slidably disposed within the housing 6. The bottom end of the housing 6 is connected to the bottom mold 1. The housing 6 protects the stamping mechanism and the bottom mold from dust contamination and prevents the cut wire from popping out of the bottom mold, increasing safety and aesthetics. Furthermore, a wire hole 11 can be provided between the housing 6 and the bottom mold 1, with semi-circular holes respectively provided at the upper end of the bottom mold 1 and the lower end of the housing 6. The two semi-circular holes are combined into a single circular hole, facilitating cleaning and maintenance of the wire hole 11.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
