The invention belongs to the technical field of moulds, and in particular relates to a sheet metal stamping die, comprising a base, a pillar and a top plate, an upper die is installed on the top plate, and a lower die base matching the upper die is arranged on the base, the Both sides of the lower mold base are provided with chutes, and a clamping assembly slides in the chute, and both sides of the lower mold base are provided with mounting seats, and a hydraulic cylinder is fixed on the mounting bases. The output end of the cylinder is connected to the clamping assembly, and a chip removal mechanism is provided on the base; the chip removal mechanism includes a tooth column that is rotatably connected to the mounting base, and the output end of the hydraulic cylinder is connected to a rack. The rack is meshed with the tooth column, and a rotating ring is arranged outside the lower mold base. The invention can fix metal plates of different sizes, spray air in multiple directions through the nozzle to clean up the waste at the inner corners of the lower die base, and set the ejection column, after the stamping is completed, Automatically lift up the sheet metal in the lower die base.
Description
technical field [0001] The invention belongs to the technical field of dies, and in particular relates to a sheet metal stamping die. Background technique [0002] The stamping die uses the die installed on the press to apply pressure to the material to cause separation or plastic deformation. In industrial production, with the improvement of the quality requirements of the metal sheet, it is necessary to stamp and shape the metal sheet through the stamping die. [0003] After searching, the national patent publication number is CN110340233B, which discloses a sheet metal stamping die, including a base, a top seat and a pillar; one end of the pillar is fixedly connected with the base, and the other end is fixedly connected with the top seat, and a transverse Rod; also includes upper top plate, No. 1 cylinder, upper die, lower die seat, drive unit, clamping unit and controller; drive unit includes No. 1 rope, turntable, No. 1 shaft, No. 1 screw and slider; clamp The tighteni...
