The positioning device comprises at least two positioning seats and at least two clamping assemblies. At least two of the positioning seats are slidably connected to the surface of the base at intervals. The sliding direction of the positioning seats and the sliding direction of the upper die are perpendicular to each other. The clamping assemblies correspond one-to-one to the positioning seats and are slidably connected to the positioning seats. When the two ends of the sheet metal correspond one-to-one to the positioning seats, the clamping assemblies clamp the ends of the sheet metal, and the clamping assemblies slide on the surface of the positioning seats under the force of the bending of the sheet metal.

[0006] By adopting the above technical scheme, the sheet metal is placed on the surface of the lower die facing the upper die, and the two positioning seats are close to or away from each other along the base surface according to the length of the sheet metal, so that the two ends of the sheet metal are facing the two positioning seats in a one-to-one correspondence, and the clamping assembly clamps the end of the sheet metal, and the upper die slides along the base surface toward the lower die. The upper die squeezes the sheet metal of the lower die to bend, and the clamping assembly slides on the surface of the positioning seat due to the bending force of the sheet metal, so that the clamping assembly always clamps the sheet metal, avoiding the horizontal displacement of the sheet metal, thereby improving the yield rate of the sheet metal bending.

[0008] By adopting the above technical scheme, when the sliding seat corresponds to the end of the sheet metal part one by one and slides close to each other along the surface of the base, one side of the sheet metal part is placed on the surface of the fixed plate, and the elastic force of the elastic part drives the clamping plate to slide along the inner wall of the sliding groove toward the fixed plate. The clamping plate surface and the fixed plate surface clamp the two sides of the sheet metal part to form a limit, and the upper die squeezes the sheet metal part on the lower die to bend it. The end of the sheet metal part drives the sliding seat to slide along the inner wall of the sliding arc groove, so that the sheet metal part is not easy to separate from the sliding seat, thereby improving the limit stability of the sheet metal part on the sliding seat, ensuring that the sheet metal part is not easy to deviate in the horizontal direction, thereby improving the yield of the sheet metal bending.
