[0039] Brief description of the usage process:

[0040] When in use, the motor 82, the cylinder 9, and the proximity sensor 8 are connected to an external controller and a power supply; a stamping die using aluminum bars as raw materials is installed below the material guide assembly 7; the disordered aluminum bars can be directly dumped into the square inclined plate 3 without being arranged, because the square inclined plate 3 is inclined, so they will roll down under the action of gravity, and some aluminum bars will cling to the side wall of the top inclined plate 4 under the action of gravity. Figure 6 ① Status shown.

[0041] Then, the cylinder 9 is activated by the external controller to be retracted to the shortest point. At this time, the top high point of the top tilting plate 4 coincides with the lowest point of the bottom of the square tilting plate 3. Under the action of gravity, the aluminum rod close to the side wall of the top tilting plate 4 rolls to the top of the top tilting plate 4 and close to the side wall of the top tilting fixed plate 5. Figure 6 ② Status shown.

[0042] Then, the cylinder 9 is started to extend by the external controller, and the top of the tilting plate 4 drives the aluminum rod to move upward. Figure 7 As shown in state ③, the control cylinder 9 continues to extend to the longest state. At this time, the top low point of the top tilting movable plate 4 coincides with the top high point of the top tilting fixed plate 5. Because the inclinations of the tops of the top tilting movable plate 4 and the top tilting fixed plate 5 are equal, Figure 7As shown in state ④, the aluminum rod will roll from the top of the top inclined movable plate 4 to the top of the top inclined fixed plate 5, then roll down from the top of the top inclined fixed plate 5 to the guide ramp 10, and then roll from the guide ramp 10 to the belt surface of the transmission belt 6, as shown in FIG. Figure 7 ⑤Status shown.

[0043] Then the motor 82 drives the driven wheel 84 to rotate through the driving wheel 83, and the driven wheel 84 drives the transmission belt 6 to transmit the aluminum rod on the belt surface of the transmission belt 6 to the material guide assembly 7. Figure 7 ⑥ As shown in the state, when the aluminum rod passes through the proximity sensor 8 and enters the material guide assembly 7, the proximity sensor 8 captures the signal of the aluminum rod passing through and transmits the signal to the external controller. The controller disconnects the circuit of the motor 82, and the transmission belt 6 loses power and stops running. The cylinder 9 does not need to be closed, because the width of the top of the top inclined moving plate 4 and the top inclined fixed plate 5 can only accommodate one group of aluminum rods. Therefore, when the aluminum rods in front are lined up, the subsequent aluminum rods will be restricted from entering the top of the transmission belt 6 and the top of the top inclined moving plate 4.

[0044] At this time, the aluminum rod reaching the material guide component 7 enters the arc recess 73 from the embedded groove 74, and falls into the mold below the material guide component 7 under the guidance of the arc recess 73, and is then punched by the punching machine. When the punching is completed, the transmission belt 6 is started again to work, and the automatic discharge, punching and feeding of the aluminum rods are realized in this reciprocating manner (the proximity sensor 8 and the external controller are both direct applications of this application and are not within the protection scope of this application, so their control principles and control circuits are omitted, and the reference model of the proximity sensor 8 can be: EVOPTICS-2-010S).

[0045] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
