DETAILED DESCRIPTION

[0015] The following is a specific embodiment of the utility model and is further described in combination with the drawings, but the utility model is not limited to these embodiments.

[0016] It should be noted that the description of the utility model about "up", "down", "left", "right", "top", "bottom" and the like is defined based on the position or relationship of the drawings shown, and is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as a limitation on the utility model.

[0017] According to Figs. 1 to 3As shown, a sheet metal stamping die includes an upper die plate 1, a lower die plate 2, an upper punch 3, and a lower punch 4. The upper punch 3 is fixedly provided with a die head 5, and the lower punch 4 is provided with a die block 6 matched with the die head 5. The upper die plate 1 and the lower die plate 2 are connected with a guide rod. The lower punch 4 is further provided with a T-shaped die groove 401, and the die block 6 is slidably embedded in the T-shaped die groove 401. The lower die plate 2 is provided with a ejector rod 11 abutting against the die block 6. The sheet metal part 10 is flat before being stamped, and is bent after being stamped. At this time, the ejector rod 11 pushes the die block 6 to a certain height, and the sheet metal part 10 is out of the T-shaped die groove 401 for easy taking.

[0018] The lower punch 4 is provided with four width adjusting plates 7, which are symmetrically arranged on the lower punch 4 in two groups. The width adjusting plates 7 are symmetrically arranged relative to the T-shaped die groove 401. The sheet metal part 10 is located between the width adjusting plates 7. The width adjusting plates 7 are further fixedly provided with a fixed plate 8. The fixed plate 8 is provided with a plurality of adjusting holes one 801, and the width adjusting plates 7 are provided with adjusting holes two 701 corresponding to the adjusting holes one 801. The fixed plate 8 and the width adjusting plates 7 are fixed on the lower punch 4 by fasteners. After the adjusting holes one 801 and the adjusting holes two 701 are matched, they are fixed on the lower punch 4 by fasteners. The adjusting holes two 701 on the width adjusting plates 7 and the adjusting holes one 801 on the fixed plate 8 can be selected and fixed according to different models of the sheet metal part 10.

[0019] The width adjusting plate 7 includes a first arc surface 702 and a second arc surface 703. The width between the two first arc surfaces 702 formed by the two width adjusting plates 7 is greater than the width between the two second arc surfaces 703. The length between the two first arc surfaces 702 formed by the two width adjusting plates 7 is less than the length between the two second arc surfaces 703. The fixed plate 8 is L-shaped, and the upper plate of the fixed plate 8 abuts against and presses the width adjusting plate 7, and the side plate of the fixed plate 8 abuts against the side surface of the lower punch 4. The interval formed by the four first arc surfaces 702 and the interval formed by the four second arc surfaces 703 are suitable for two different models of the sheet metal part 10. After the width adjusting plates 7 are fixed, the intervals formed by different arc surfaces can be suitable for different models of the sheet metal, reducing the installation process and improving the processing efficiency. The width adjusting plate 7 is further provided with a U-shaped hole 704, and the fixed plate 8 is provided with a fixed hole 802. The square fixing block 9 passes through the fixed hole 802 and the U-shaped hole 704, and one end of the square fixing block 9 is fixedly embedded in the lower punch 4. The U-shaped hole 704 on the width adjusting plate 7 can prevent the width adjusting plate 7 from deviating during the movement and adjustment process, making the adjustment process more convenient.

[0020] The above embodiments are only preferred embodiments of the utility model, not to limit the protection scope of the utility model thus, all equivalent changes made according to the structure, shape, principle of the utility model should be covered in the protection scope defined by the utility model claims.
