[0030] Please refer to Figure 1-2 , the present utility model provides a technical solution: a sheet metal stamping die with a special-shaped floating pipe position, including:

[0031] The upper die fixing unit, which includes an upper die base 1, an upper clamping plate 2, and a blanking plate 3, and the upper die base 1, the upper clamping plate 2, and the blanking plate 3 are locked together in sequence;

[0032] The lower die unit, which includes a lower template 6, a lower die base 8, a lower pad foot 9, and a lower locking plate 10. The lower template 6 and the lower die base 8 are locked together. The lower pad foot 9 is connected to the bottom of the lower die base 8. The lower locking plate 10 is connected to the lower pad foot 9. An active pipe position 4 and a fixed pipe position 11 are arranged on the lower template 6. A pressing block 5 is arranged on the side end of the active pipe position 4. A screw passes through the pressing block 5 and is connected to the lower die base 8. A spring 7 is arranged at the bottom of the active pipe position 4. The spring 7 passes through the lower template 6 and is connected to the lower die base 8. A vacuum suction component 12 is arranged between the active pipe position 4 and the fixed pipe position 11. The vacuum suction component 12 passes through the lower die base 8 and extends to the top of the lower template 6.

[0033] A limiting groove 13 is arranged on the blanking plate 3, and the width of the limiting groove 13 matches the width of the active pipe position 4. A sliding groove is arranged on the blanking plate. The limiting groove body can be adjustably connected in the sliding groove. A limiting groove is arranged in the limiting groove body. By accommodating sheet metals of different lengths, the displacement that the active pipe position needs to move can be obtained, so as to adjust the position of the limiting groove, and ensure that the top of the active pipe position is located in the limiting groove during stamping, reducing the influence of the vibration of the sheet metal during stamping.

[0034] The vacuum suction component 12 includes a vacuum pump 121, a vacuum pipeline 122, and a vacuum suction nozzle 123. The vacuum suction nozzle 123 is connected to the vacuum pipeline 122. The vacuum pipeline 122 is connected to the vacuum pump 121. The vacuum pump 121 is installed at the bottom of the lower die base 8.

[0035] The top of the vacuum suction nozzle 123 is flush with the top surface of the lower template.

[0036] The number of the vacuum suction attachments 12 is at least two or more, and a plurality of the vacuum suction attachments 12 are evenly arranged at equal intervals between the movable pipe position 4 and the fixed pipe position 11.

[0037] A first inclined surface 14 is provided on the movable pipe position 4, and a second inclined surface 15 is provided on the fixed pipe position 11. The inclination height of the first inclined surface 14 is greater than that of the second inclined surface 15. The downward movement path of the sheet metal stamping is planned so that the inclined surface on one fixed pipe position can well cooperate with the inclined surface on the movable pipe position, so that the cooperation of the two can meet the positioning stamping of sheet metals of various lengths. At the same time, the vacuum suction attachment is cooperated to avoid displacement during the stamping process, and the position of the limiting groove of the stripper plate can be adjusted according to sheet metals of different lengths.

[0038] Working principle: Place the movable pipe position in the cavity of the lower template, place a spring below to lift the movable pipe position, and fix it with a pressing block. The movable pipe position can move up and down in the cavity. The side close to the product is an inclined surface, and the material is pressed on the inclined surface. The movable pipe position can move up and down. By using the inclined surface, the purpose of clamping the material can be achieved. At the same time, in cooperation with the vacuum suction attachment, when the sheet metal moves onto the lower template along the inclined surface, the top of the movable pipe position is limited in the limiting groove, and the bottom is adsorbed by the vacuum suction nozzle, avoiding the displacement of the sheet metal caused by the shaking of the equipment during the stamping process and affecting the stamping quality.

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
