To further clarify the objects, structures, features and functions of the present invention, a detailed description will be given below with reference to fig. 1-3 and the embodiments.

In the present case, adopted the stamping equipment of a sheetmetal, realized the high efficiency adaptation punching press to the sheetmetal, its overall structure is including last punching component and lower punching component to sheet metal shaping punching press through removable last mould 16 and the lower mould 17 realization multiple structure pattern, specific structure is as follows:

a lower die stamping assembly:

the lower die stamping component is provided with a base plate 4 arranged on a base 5, a lower die 17 is detachably arranged in the middle of the base plate 4, a feeding guide plate 10 is arranged at one end of the base plate 4, the feeding guide plate 10 is provided with a guide groove 101, the bottom groove of the guide groove and the upper end face of the lower die 17 are located on the same horizontal plane, and the guide groove 101 is arranged along the length direction of the base plate 4 to convey a metal sheet to the upper end face of the lower die 17.

Here, as will be understood by those skilled in the art, in order to achieve the installation of the backing plate 4 and other components, the base 5 is used not only for providing a mounting surface and support, but also for supporting the bottom portion with a plurality of vertical plate members and forming a gap area for allowing the blanking. Specifically, the upper end surface of the base 5 is a horizontal surface, a backing plate 4 is fixedly arranged in a horizontal direction, the backing plate 4 is of a substantially rectangular plate structure, the upper end surface of the backing plate 4 is set to be the horizontal surface for facilitating the installation of parts, the backing plate 4 is provided with a first end portion 41 at one end and a second end portion 42 at the other end, a feeding guide plate 10 is fixedly arranged on the first end portion 41, and a guide groove 101 formed by the feeding guide plate 10 provides a track for metal sheets to stably move along the guide groove 101. The lower die 17 is arranged in the middle of the base plate 4, it can be understood that the lower die 17 can be replaced for matching with punching metal sheets with different types and styles, generally speaking, a notch with a size matched with the lower die is arranged in the middle of the end face of the base plate 4, after the lower die 17 is placed in the notch, the upper end face of the lower die 17 is just flush with the upper end face of the base plate 4, it can also be understood that the metal sheets move to the upper end face of the lower die 17 from the guide groove 101 and are punched, and in order to ensure the stability of the metal sheets in the conveying process, the bottom of the guide groove 101 and the upper end face of the base plate 4 are located on the same horizontal plane.

What need be said emphatically, the present case has adopted first deflector 6, second deflector 7 and has taken off flitch 9, has realized the stable use of stamping process, but the sheetmetal of different width versions of adaptation simultaneously has improved the suitability, and the concrete improvement is as follows:

the first guide plate 6 and the second guide plate 7 are relatively position-adjustably mounted on the base plate 4, and a space region in which the width is changed by the relative position adjustment is formed between the first guide plate 6 and the second guide plate 7, the upper end surface of the lower die 17 is located at the bottom of the space region, and the space region and the guide groove 101 are located in the same linear direction.

Here, it can be understood by those skilled in the art that the first guide plate 6 and the second guide plate 7 have a symmetrical structure, and a gap region with an adjustable gap width is formed between the inner side surfaces, the spacing region is positioned on the extension line of the guide groove 101 and provides a path through which the metal sheet can pass, specifically, the first guide plate 6 and the second guide plate 7 are both formed with an open groove 20 along the direction perpendicular to the length direction of the spacing region at the outer edge, an adjusting screw with the end part screwed in the backing plate 4 is arranged in the open groove 20, the first guide plate 6 and the second guide plate 7 are both adjusted through the tightness of the adjusting screw 19 so as to drive the adjusting screw to adjustably move along the opening direction of the open slot 20, i.e. in the width direction of the underlay sheet 4, the width of the spacer areas is changed by the adjustment of the tightness in order to adapt to metal sheets of different widths.

The lower end face of the stripper plate 9 is provided with a bulge 91 matched with the interval area along the central line thereof, the stripper plate 9 is positioned above the first guide plate 6 and the second guide plate 7 and elastically connected with the backing plate 4, a feeding channel 15 for the metal sheet to pass through is formed between the lower end face of the bulge 91 and the upper end face of the backing plate 4, and the feeding channel 15 is formed at the bottom of the interval area.

Here, it can be understood by those skilled in the art that the protrusion 91 is used for adaptive embedding into the spaced area. Specifically, a plurality of uniformly distributed rectangular springs 8 are mounted on the stripper plate 9, one end of each rectangular spring 8 is connected to the stripper plate 9, and the other end of each rectangular spring 8 abuts against the upper end face of the backing plate 4, so that the highest channel height and the lowest channel height of the feeding channel 15 can be limited by the rectangular springs 8. And a guide channel 18 for the upper die 16 to freely pass through and matching with the lower die 17 in the vertical direction is formed in the middle of the stripper plate 9, in the implementation, the guide channel 18 is used for the upper die 16 to pass through, the upper die 16 passes through and then is stamped to a metal sheet, waste is discharged from a waste outlet 11 arranged at the bottom, and the waste outlet 11 penetrates through the thickness of the backing plate 4 and the base 5.

In another embodiment, the upper die stamping assembly further comprises a mounting plate 14 for mounting the upper die 16, and a gas-liquid pressurizing cylinder 2 located above the upper die 16, wherein an output end of the gas-liquid pressurizing cylinder 2 is connected to the upper die 16 to drive the upper die 16 to point to the lower die 17 and move telescopically, a plurality of vertically arranged nitrogen springs 12 are mounted at the edge of the mounting plate 14, the nitrogen springs 12 have elastic parts 121, and when the upper die is demolded, the end parts of the elastic parts 121 elastically contact with the upper end surface of the stripper plate 9 to drive the stripper plate 9 to have a preset pressure.

Here, be provided with the mounting panel 1 that is used for setting firmly gas-liquid pressure cylinder 2 above mounting panel 14, the connecting rod 3 support connection of vertical setting is passed through at four edges of mounting panel 1 on base 5, adjusting nut 13 is still installed to the output axle head of gas-liquid pressure cylinder 2 simultaneously to realize adjusting the relative position height of last mould 16, in the implementation, go up mould 16 because the elastic force that nitrogen spring 12 itself possessed in the drawing of patterns in-process, can make last mould 16 have relative elastic force, make stripper plate 9 keep certain pressure throughout its liter in-process, in order to guarantee that inside sheetmetal is indeformable.

The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
