A guide groove 23 is formed between the two guide plates 22. The material 200 is located in the guide chute 23, and the feeding assembly 20 conveys the material 200 to a processing station, so that automatic production is realized, and the production efficiency is improved.

The positioning block 30 is fixed to the lower die holder 10. The number of the positioning blocks 30 is four.

The cutting die 40 is provided with a first pressing surface 41. The first press surface 41 is located at the end of the cutting die 40. The first stamping surface 41 includes two protruding portions and a recessed portion. The concave part is positioned between the two convex parts. The cutting die 40 is fixed to the lower die holder 10. The positioning blocks 30 are provided on both sides of the cutting mold 40. The two positioning blocks 30 clamp and cut off the material 200 on the forming die 40, so as to prevent the material 200 from overturning or falling.

The roll forming die 50 includes a forming post 51. The forming column 51 is cylindrical. The forming post 51 is located at the end of the rounding die 50. The roll forming die 50 is fixed to the lower die holder 10. The positioning blocks 30 are respectively arranged at two sides of the rolling forming die 50. The two positioning blocks 30 clamp the semi-finished product to prevent the semi-finished product from overturning or falling.

The punch assembly 60 includes an upper die holder 61, a round forming punch 62, and a cut forming punch 63. The round forming punch 62 and the cutting forming punch 63 are fixed to the upper die holder 61. The rolling forming punch 62 is provided with a forming surface 620, and the cross section of the forming surface 620 is semicircular. The forming surface 620 is located on the end of the rounding punch 62 remote from the upper die holder 61. The cutting forming punch 63 is provided with a second punching surface 630. The shape of the second press surface 630 corresponds to the shape of the first press surface 41. The second stamping surface 630 is located at an end of the cutting forming punch 63 remote from the upper die holder 61. The rounding punch 62 is located above the rounding die 50, and the cutting punch 63 is located above the cutting die 40.

The pusher assembly 70 includes a base plate 71, a driver 72, a guide block 73, a connecting block 74, a push rod 75, and a push rod 76. The driving member 72 is fixed to the bottom plate 71.
