Detailed ways

The following describes in detail the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, but should not be construed as a limitation of the present invention.

As shown in Figures 1 to 5, the present utility model discloses a bending punching machine, comprising a fixed seat 1, a supporting frame 2 and a punching cylinder 3, the fixing seat 1 and the supporting frame 2 are connected, and the punching cylinder 3 is fixed on the supporting frame 2 at the front end, wherein: the punching cylinder 3 is provided with a punching head 5, the punching head 5 and the punching cylinder 3 are connected by a pushing shaft 301, and the upper surface of the fixed seat 1 is provided with a rail 6 and a die 7. The upper surface is provided with a punching groove 701 , the lower surface of the mold 7 is provided with a mold mounting groove 702 , and the rail 6 is placed in the mold mounting groove 702 .

Through this structure, the upper surface of the mold 7 is provided with a punching groove 701, the lower surface of the mold 7 is provided with a mold installation groove 702, and the rail 6 is placed in the mold installation groove 702, which is convenient for mold replacement and improves production efficiency.

When it is time to replace the mold 7, the mold 7 can be directly pushed off the track 6, and other molds can be replaced, so as to meet the needs of different processing. In addition, the steel plate to be processed is placed on the die 7, the punching cylinder 3 pushes the punching head 5 to move downward, and punches the position of the steel plate that needs to be processed.
