Working principle of the invention:

The first step is to start the main body 1 of the cold heading machine, transmit power through pulleys and gears, perform linear motion through the crank connecting rod and slider mechanism, and use the punch and concave mold to plastically deform the blank of the processed part (nut) Or separate, and move the plasticized nut from the production station to the discharge port through the built-in conveyor, and finally fall into the material receiving chute 21;

In the second step, it drops directly into the filter frame 3, starts four vibration motors 35 synchronously, and drives the filter frame 3 to vibrate reciprocally in the material receiving tank 2 along the vertical direction of its inclined surface, plus the filter frame 3 It is designed to be inclined downward, so the nuts dropped in the filter frame 3 will continue to roll down to the right frame opening, and then fall into the small cavity formed by the baffle 22 separating the material receiving slot 21, and finally Falling into the connecting hose 54, several nuts will be evenly spread on the bottom of the entire inner cavity of the filter frame 3 during the continuous rolling process, and with the overall vibration of the filter frame 3, the nuts will be damaged due to the mechanical cold heading process. The metal debris attached to the surface is shaken and falls down, and while the nut rolls down, a number of nozzles 34 on both inner walls of the filter frame 3 will spray water concentratedly toward each other to help the metal debris detach from the nut surface, and the water flow will flow due to gravity. The filter holes at the bottom of the inner cavity of the filter frame 3 fall into the material receiving groove 21. In this process, the metal debris that has been separated from the nut surface will be brought in together, which will help each other to improve the cleaning effect;

In the third step, the nuts entering the connecting hose 54 will fall into the storage box 53, and start the conveying motor 58 to drive the spiral shaft and the spiral conveying piece 57 wound and fixed on the outer wall of the spiral shaft to rotate at a constant speed and at a low speed. The nuts will evenly fall out of the delivery tube 55 from the discharge tube installed at the end of the delivery tube 55, and the reduction motor 56 can be started to drive the storage box 53, the delivery tube 55, the screw conveyor 57 and the discharge tube to rotate synchronously. The height of the final drop point of the nut can be adapted to the material receiving equipment of different specifications. During the rotation of the conveying pipe 55, the connecting hose 54 will rotate synchronously (at a small angle). At this time, the connecting hose 54 will have a small amplitude. movement, but always ensure that one end is connected to the nut discharge port 25, and the other end is connected to the inner cavity of the storage box 53;

In the fourth step, the metal debris and water flow entering the bottom of the material receiving tank 21 will be pumped out by the water pump 46, but the drive motor 43 can be started to drive the corresponding rotating drum 44 to rotate, because the two rotating drums 44 are conveyed through the metal mesh conveyor belt 45 transmission, so another rotating drum 44 will also assist in synchronous rotation, which makes the metal mesh conveyor belt 45 rotate stably. Since the metal mesh conveyor belt 45 passes between the water pump 46 and the inlet chamber 41, it will block the metal debris. The debris passes through, allowing the water flow to enter normally, preventing metal debris from entering the water pump 46, the return water pipe 49 and the nozzle 34, affecting the normal use of the water circulation system, and the blocked metal debris will remain in the mesh of the metal mesh conveyor belt 45 Inside, as the metal mesh conveyor belt 45 rotates and moves to the bottom, these metal debris will sway and fall due to gravity and the mechanical stress of synchronous circular motion plus the impact of the water flow supplied by the water pump 46 to the spray shower (the water pump 46 is supplying return flow When the water pipe 49 supplies water, it will also supply water to the spray shower. The water sprayed by the spray shower plus its own gravity will impact the inner ring wall of the metal mesh conveyor belt 45), and eventually the metal debris will fall from the discharge chamber 42. , realizes the centralized collection of metal debris, and further has the characteristics of convenient collection.
