DETAILED DESCRIPTION

[0017] In order to more intuitively and completely understand the technical solution of the present invention, a non-limiting feature description is now provided in conjunction with the accompanying drawings of the present invention as follows:

[0018] like Figure 1 and Figure 2 As shown, the striking head stamping die includes an upper die 100 and a lower die 200, and a round metal is placed between the upper die 100 and the lower die 200. The round metal is preferably a round iron wire, and a punching double-sided positioning edge station 1, a lower latch-type positioning station 2, an upper and lower hedging cold heading forming station 3, a first upper latch-type positioning station 4, an upper and lower hedging rounding shaping station 5, a second upper latch-type positioning station 6, a slider-type sleeve hole shaping station 7 and a cutting and discharging station 8 are sequentially arranged between the upper die 100 and the lower die 200 in the horizontal direction.

[0019] The double-sided positioning edge punching station 1 comprises a double-sided positioning groove punch 1.1 arranged at the lower end of the upper die 100 and a lower punch positioning groove blade 1.2 arranged at the upper end of the lower die 200. The round iron wire enters the die and first punches the positioning edge. The positioning edge is used to prevent the round metal material from twisting in the die, ensuring the positioning accuracy of each step.

[0020] The lower latch type positioning station 2 comprises a lower floating guide positioning block 2.1 arranged at the upper end of the lower mold 200.

[0021] The upper and lower counter-punching cold heading forming station 3 includes an upper semicircular cold heading floating lifting block 3.1 arranged at the lower end of the upper die 100 and a lower semicircular cold heading floating lifting block 3.2 arranged at the upper end of the lower die 200. Punches are arranged in the upper semicircular cold heading floating lifting block 3.1 and the lower semicircular cold heading floating lifting block 3.2. The upper semicircular cold heading floating lifting block 3.1 and the lower semicircular cold heading floating lifting block 3.2 clamp the round iron wire at the same time, and then the punches inside them counter-punch the cold heading forming from top to bottom, thereby ensuring the appearance integrity of the product.

[0022] The first upper latch type positioning station 4 comprises a first upper step positioning punch 4 . 1 arranged at the lower end of the upper die 100 .

[0023] The upper and lower punching and rounding shaping stations 5 include an upper shaping and stripping block 5.1 arranged at the lower end of the upper die 100 and a lower shaping and stripping block 5.2 arranged at the upper end of the lower die 200.

[0024] The second upper latch type positioning station 6 includes a second upper step distance positioning punch 6.1 arranged at the lower end of the upper die 100. The lower latch type positioning station 2, the first upper latch type positioning station 4, and the second upper latch type positioning station 6 respectively use the lower floating guide positioning block 2.1, the first upper step distance positioning punch 4.1, and the second upper step distance positioning punch 6.1 to insert the positioning edge cut on the round iron wire by the punching and cutting double-sided positioning edge station 1, accurately positioning the accuracy of each step station, ensuring that the step size of each step station is the same.

[0025] The slider-type hole shaping station 7 comprises an upper shaping pressing block 7.1 arranged at the lower end of the upper die 100 and a lower hole shaping slider 7.2 arranged at the upper end of the lower die 200.

[0026] The cutting and unloading station 8 comprises an upper cutting punch fixing block 8.1 arranged at the lower end of the upper die 100 and a waste falling knife edge 8.2 arranged at the upper end of the lower die 200.

[0027] During processing, the round iron wire is fed into the mold through a feeder, and multiple processing stations are completed inside the mold. Multi-station forming ensures the dimensional stability of the product and improves production capacity.

[0028] Of course, the above are only preferred embodiments of the present invention, and the patent scope of the present invention is not limited thereto. All simple modifications and equivalent structural changes made using the contents of the specification and drawings of the present invention should be included in the patent protection scope of the present invention.
