As shown in fig. 1 to 5, a flanging die for a television backboard outlet, comprising:

the plate body 1 is provided with a vertical part 11 in a stamping mode, and the vertical part 11 encloses a vertical groove 12;

the upper punch seat 2 comprises a rod body 21 and a punch 22 extending from the rod body 21 in an arc shape, the diameter of the punch 22 is smaller than that of the rod body 21, the diameter of the punch 22 is matched with that of the vertical groove 12, and a guide wall 3 is arranged between the punch 22 and the rod body 21;

a base 4, wherein the base 4 is arranged below the upper punch seat 2, and the base 4 is provided with a punching groove 41 matched with the punch 22;

when the upper punch holder 2 and the base 4 are clamped, the guide wall 3 can drive the vertical part 11 to deform along a preset direction and fold the plate body 1 and the vertical part 11.

In the actual stamping die, a plurality of groups of flanging dies are arranged, during actual processing, the plate body 1 is placed on the lower die, at the moment, the vertical groove 12 and the punching groove 41 of the base are oppositely arranged to realize positioning, firstly, the upper punching seat 2 is driven by the upper die to move downwards, firstly, the punching head 22 stretches into the vertical groove 12, the vertical part 11 is contacted with the outer wall surface of the punching head 22 (namely, the second wall surface 52), and is firstly bent under the guide of the guide wall 3 of the punching head 22, and then punching is carried out, so that a smooth appearance opening is formed between the vertical part 11 and the diameter of the plate body 1, and damage to cables is avoided.

Specifically, the punch 22 is in the form of an elongated block.

More specifically, the lower wall of the rod 21 is a first wall surface, the outer periphery of the punch 22 is a second wall surface 52, a first chamfer wall 61 is provided at a position where the first wall surface 51 and the second wall surface 52 are joined, and the base is provided with a second chamfer wall 62 matched with the first chamfer wall 61. When the punch 22 and the base are clamped, the first and second chamfer walls 61 and 62 are fitted together, so that the wire outlet hole 100 forms a smooth wall surface, which damages the outer wall of the cable and hurts workers during assembly.

In the embodiment of the present utility model, the bottom wall of the punch 22 is a third wall surface 53, and a third chamfer wall 63 is disposed at the joint end of the third wall surface 53 and the second wall surface 52, where the third chamfer wall 63 can enable the punch 22 to smoothly extend into the vertical slot 12.
