The inner stripping top leans, the stripping plate inner stripping is set in the stripping plate, the upper end of the inclined wedge is fixed on the upper backing plate, and the lower end of the inclined wedge penetrates into the stopper plate and the stripping plate and is connected with the slider punch. The outer side leans against, the slider punch is slidingly connected in the slider fixing seat and can move in the horizontal direction, the slider fixing seat is fixedly installed in the stripping plate, and the slider spring is arranged between the slider punch and the slider fixing seat Between, the upper end of the anti-push rod is fixed in the upper backing plate and the upper splint, and the gap between the lower end of the anti-push rod is inserted in the stopper plate and the stripper plate and passes through the stripper plate;

The lower formwork, lower backing plate, and lower mold base are fixedly stacked together in sequence, the gap of the floating head is set in the side cutting die, the bottom surface of the floating head is pressed against the floating head spring through the floating head ejector rod, and the floating head spring is sleeved in the lower mold base The inner and side cutting dies are installed on the die fixing plate, and the die fixing plate is fixedly installed on the lower formwork.

After adopting the above scheme, because the utility model pushes the slider punch to slide laterally through the oblique wedge, and finally cuts into the side cutting die to realize the punching of the four corners of the square drawing part, and then realizes the reset of the slider punch by the slider spring , The side cutting action is mainly completed by the inclined wedge, the slider punch, the side cutting die and other components, which has the advantages of stable and reliable action.

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

detailed description

As shown in Fig. 1-Fig. 3, the utility model is a corner side cutting die for drawing parts, including an upper cover plate 1, an upper template 2, an upper backing plate 3, an upper clamping plate 4, a stopper plate 5, and a stripping plate 6. Lower mold plate 7, lower backing plate 8, lower mold seat 9, stripping plate spring 10, ejector rod 11, ejector rod spring 12, inner stripping plate 13, inclined wedge 14, reverse push rod 15, slider fixing seat 16. Slider punch 17, slider spring 18, floating head 19, floating head ejector rod 20, floating head spring 21, die fixing plate 22, side cutting die 23.

The upper cover plate 1 , upper template 2 , upper backing plate 3 , and upper splint 4 are sequentially fixedly stacked together, and the stopper plate 5 and the stripper plate 6 are fixedly stacked together. The stripping plate spring 10 is arranged between the upper template 2 and the stopper plate 5, the ejector rod spring 12 is sleeved in the upper cover plate 1 and the upper template 2, and the upper end of the ejector rod 11 is fixed on the upper backing plate 3 and the upper template. In the splint 4, the gap between the lower end of the ejector rod 11 is inserted in the stopper plate 5 and the stripper plate 6 and leans against the inner stripper 13 of the stripper plate. The upper end is fixed on the upper backing plate 3, and the lower end gap of the wedge 14 penetrates the stop plate 5 and the stripper plate 6 and abuts against the outside of the slider punch 17, and the slider punch 17 is slid on the slider and fixed Inside the seat 16 and can move in the horizontal direction, the slider fixing seat 16 is fixedly installed in the stripping plate 6, the slider spring 18 is arranged between the slider punch 17 and the slider fixing seat 16, and the upper end of the reverse push rod 15 is fixed In the upper backing plate 3 and the upper clamping plate 4 , the lower end of the reverse push rod 15 passes through the stopper plate 5 and the stripping plate 6 and passes through the stripping plate 6 .

The lower template 7, the lower backing plate 8, and the lower mold base 9 are sequentially fixed and stacked together, the floating head 19 is nested in the side cutting die 23, and the bottom surface of the floating head 19 is pressed against the floating head spring 21 through the floating head ejector rod 10. , the floating head spring 21 is sleeved in the lower mold base 9, the side cutting die 23 is installed on the die fixing plate 22, and the die fixing plate 22 is fixedly installed on the lower template 9.

Working principle of the utility model:

The mold goes down, and the reverse push rod 15 pushes the floating head 19 into the side-cutting die 23, and fits the die fixing plate 22; at the same time, the stripping plate 6 and the side-cutting die 23 ensure a 0.15mm gap. When the side-cut die 23 enters the cavity of the stripper plate 6, it is pressed by the stripper plate spring 10. When the wedge 14 goes down, it pushes the 1 slider punch 17 to slide sideways, and finally cuts into the side-cut die 23 to realize square drawing. Die-cut corners for deep pieces.

The utility model is a new type of punching method in which the die is on the lower template and the side cutting punch is on the stripper plate. Less than 0.018mm, the material thickness is 0.15mm, and the punching gap is only 0.007mm, which greatly increases the difficulty of the mold.

The above is only a preferred embodiment of the utility model, so the scope of implementation of the utility model cannot be limited with this, that is, the equivalent changes and modifications made according to the patent scope of the utility model and the content of the specification should still belong to the utility model. Within the scope covered by the utility model patent.
