The specific implementation modes of the present invention are described in detail in combination with the drawings in the specification.

[0030] Traditional punching machines rely on manual placement of sheet metal materials, which can easily cause the stamping position to shift due to visual errors or unstable operation, affecting accuracy. Manual loading is inefficient and difficult to adapt to continuous production needs, and there are safety hazards. Some automatic feeding mechanisms only realize basic conveying functions and lack the ability to dynamically adjust the stamping position, resulting in insufficient material positioning accuracy. The unloading and packaging links after stamping still require manual intervention, and the degree of automation is low.

[0031] The present invention realizes automatic sheet metal conveying through the electric roller 15, and can adjust the horizontal position of the material in combination with the first roller 7 in the lifting rail, which can solve the problem of manual positioning accuracy.

[0042] A transfer box 34 is placed on the top of the conveying shaft 27, and a plurality of partition plates 35 are fixedly installed on the inner wall of the transfer box 34 at equal intervals.

A blocking frame 33 is provided above the transfer box 34, and the outer wall of the blocking frame 33 is fixedly connected to the connecting arm 32.

[0043] In the above structure, after the sheet metal is discharged along the roller 25, its end portion abuts against the blocking frame 33 and slides into the transfer box 34.
