Description

Small-opening U-shaped section aluminum profile forming die

Technical Field

The utility model relates to an aluminum profile die, in particular to a small-opening U-shaped section aluminum profile forming die.

Background

The aluminum profile is obtained by extruding an aluminum alloy material on an extruder through an aluminum profile die. The existing aluminum profile die comprises an upper die and a lower die, wherein the upper die is provided with a feeding port, and the lower die is provided with a discharging port. As shown in fig. 1, the aluminum profile 10 has an opening 101 on one side, and because the opening 101 has a small size, the conventional processing methods have two types: in the first processing method, since the male head used for molding is small, in order to avoid the deviation of the male head, a transverse small male head needs to be arranged on the male head at a position opposite to the opening, so that a rib 102 is formed on the molded aluminum profile 10 at the position, and after the molding, the rib 102 is removed, and a plurality of rib removing processes are performed; the second processing method is to make the male end for forming the opening 101 large, so that the size of the opening 101 is increased, the opening 101 is shaped after forming, and a plurality of shaping processes are performed, meanwhile, because two ribs 103 on the aluminum profile 10 are connected with the outer side surface of the aluminum profile 10, after shaping, the position is easy to bulge, and the appearance of a product is affected. Both of the above-mentioned processing methods are complicated.
