[0027] An adsorption mold assembly 3 is provided, comprising multiple sets of horizontally and equidistantly fixed on the upper end of a mold platform 2. The adsorption mold assembly 3 includes a punch 31, an annular pipe 32, and suction tubes 33. The punch 31 is fixed on the upper end of the mold platform 2, and has a punch 34 at its upper end. The lower part of the punch 34 passes through the mold platform 2 and the base 11. An annular pipe 32 is located inside the punch 31 and outside the punch 34. Multiple suction tubes 33 are evenly fixed in a ring on the upper end of the annular pipe 32, with the upper end of each suction tube penetrating the punch 31. The upper surface of the suction tubes 33 is flush with the upper surface of the punch 31. When raw metal materials are placed on the punch 31, air is drawn in through the suction tubes 33, adsorbing the raw metal materials onto the punch 31 to prevent displacement. Simultaneously, batch forming of metal terminals can be achieved.

[0028] The air tube assembly 6 is connected to the rear of the adsorption mold assembly 3. The air tube assembly 6 includes a diverter pipe 61, a branch pipe 62, a connecting pipe 63, a filter element 64, and a pump pipe 65. The branch pipe 62 is fixed to the rear end of the annular pipe 32. The diverter pipe 61 is fixed to the rear of the branch pipe 62. The connecting pipe 63 is fixed to the rear end of the diverter pipe 61. The filter element 64 is flanged and connected to the rear end of the connecting pipe 63. The pump pipe 65 is flanged and connected to the rear end of the filter element 64. A vacuum pump is connected to the end of the pump pipe 65. Through the vacuum pump, the suction pipe 33 can be sucked in by the pump pipe 65, the connecting pipe 63, the diverter pipe 61, the branch pipe 62, and the annular pipe 32. During the suction process, the filter element 64 can prevent metal waste from being sucked into the vacuum pump and affecting the service life of the vacuum pump.

[0029] A bending assembly 4 is mounted on the upper side of the support assembly 1. The bending assembly 4 includes a concave frame 41, a cylinder 42, guide rods 43, and a die 44. The concave frame 41 is disposed between the top plate 13 and the base 11. The cylinder 42 is fixedly mounted on the upper end of the top plate 13, and the end of the piston rod of the cylinder 42 passes through the top plate 13 and is fixed to the concave frame 41. There is a pair of guide rods 43, which are respectively fixed on both sides of the upper end of the concave frame 41. The upper part of the guide rod 43 is flush with the top plate. 13. The activity is continuous. There are multiple concave dies 44 and they are fixed at the lower part of the concave frame 41. The concave dies 44 correspond one-to-one with the punches 31. The concave dies 44 have guide holes 46 in the middle. The guide holes 46 correspond one-to-one with the punches 34. A connecting plate 45 is fixed between adjacent concave dies 44. After the metal raw material is adsorbed on the punches 31, the concave frame 41 is pushed down by the cylinder 42. The concave frame 41 drives the concave dies 44 to press down on the metal raw material to bend and form the metal raw material.

[0030] The stamping assembly 5 is installed inside the bending assembly 4. The stamping assembly 5 includes a second cylinder 51, a pressure plate 52, and a punch 53.

There are multiple punches 53, which are fixed to the lower end of the pressure plate 52. The punches 53 correspond one-to-one with the guide holes 46. The second cylinder 51 is fixedly installed at the top inside the die frame 41. The piston rod end of the second cylinder 51 is fixed to the pressure plate 52. After the metal raw material is bent and formed, the pressure plate 52 is pushed down by the second cylinder 51. The pressure plate 52 drives the punch 53 to move down through the guide hole 46 of the die 44 and punch a hole in the bent metal terminal. The punched waste will fall down along the punch hole 34 and out of the base 11.

[0031] Working principle: The raw metal material is placed on the punch 31. A vacuum pump, using pump pipe 65, connecting pipe 63, branch pipe 61, branch pipe 62, and annular pipe 32, draws air through suction pipe 33. During suction, filter element 64 prevents metal scraps from being drawn into the vacuum pump, thus extending its lifespan. Suction through suction pipe 33 adheres the raw metal material to the punch 31, preventing displacement. Then, cylinder 42 pushes the concave frame 41 downwards. The moving die 44 presses down on the metal raw material to bend and form it. Then, the cylinder 51 pushes the pressure plate 52 downward. The pressure plate 52 drives the punch 53 downward through the guide hole 46 of the die 44 and punches the bent metal terminal. The punched waste material falls down along the punch hole 34 and out of the base 11. This achieves bending and punching of the bent metal terminal in one step, improving efficiency and enabling batch forming of metal terminals. The formed metal terminals are as follows: Figure 5 As shown.
