Detailed Description

The principles and features of the present utility model are described below in connection with examples, which are set forth only to illustrate the present utility model and not to limit the scope of the utility model.

As shown in fig. 1 to 5, a flanging forming die comprises an upper die 1, a lower die 2 and a pressing body 3, wherein the upper die 1 and the lower die 2 are arranged up and down relatively, a cavity is arranged in the middle of the lower die 2, the pressing body 3 is arranged in the cavity in the middle of the lower die 2, pressing inserts 6 are symmetrically arranged on two sides of the pressing body 3, a plurality of pit inserts 7 are inlaid on the pressing inserts 6 at intervals, the pit inserts 7 protrude out of the upper end face of the pressing inserts 6, and a plurality of pits are arranged on the upper end face of the pit inserts 7.

More specifically, the two sides of the upper die 1 are symmetrically provided with a flanging upper insert 4, the two sides of the middle cavity of the lower die 2 are provided with flanging lower inserts 5, and the flanging upper insert 4, the flanging lower inserts 5 and the pressing inserts 6 on the same side jointly enclose an L-shaped cavity.

In addition, in the present embodiment, the present utility model,

the pock insert 7 is in a cylindrical shape, the upper end face of the pock insert 7 is provided with a plurality of V-shaped grooves which are engraved in a crossing mode, and a plurality of pocks are formed on the upper end face of the pock insert 7.

More specifically, the specification of the pock insert 7 is a cylinder with the diameter of 40 and the height of 18.5mm, and of course, the diameter and the height of the pock insert 7 can be changed according to the size of the part. The upper surface of the insert is a cross-carved V-shaped groove, the opening angle alpha of the V-shaped groove is 60 degrees, the depth is 1mm, the size interval between the parallel V-shaped grooves is 1mm, after cross carving, pits of 1x1mm are formed on the surface, the material of the pit insert 7 is T10A high-carbon tool steel or Cr12MoV cold working die steel or a material with the same strength range after quenching, and the quenching hardness is HRC58-62. The material pressing insert 6 is provided with a counter bore, the depth of the counter bore is 18mm, the center of the pit insert 7 is provided with a disassembly threaded hole of the M8, the pit insert 7 is embedded in the counter bore and then fixed on the material pressing insert 6 through a bolt, and the pit insert 7 protrudes out of the upper end face of the material pressing insert 6 by 0.5mm.
