At this time, the movement of the third support plate 115 The dynamic state is diagonal movement. Through the engagement of the driven gear 119 and the tooth groove 122, the driven gear 119 rotates clockwise, thereby driving the rotating rod 117 to rotate clockwise, so that the fourth support plate 114 rotates clockwise, so that the fourth support plate 114 gradually rotates, and the nut blanks on the fourth support plate 114 slide onto the nut conveyor belt 104, so that the nut blanks can return to the nut conveyor belt 104 after falling, realizing fully automatic processing, without the need for manual sorting or picking up of fallen nut blanks, saving manpower and improving the processing efficiency of nut blanks.

[0023] Embodiment 2: A mobile phone nut processing process, comprising: S1, the nut forming machine is driven by hydraulic pressure to press out the initial shape of the nut that meets the standard in a short time.
