Detailed Description
As shown in fig. 1, fig. 1 is a schematic structural diagram of a forming mold for automobile decoration tail pipe according to the present invention.
Referring to fig. 1, the invention provides a forming mold for an automobile decoration tail throat, comprising: a crimping female die 1 and a necking female die 2;
hemming die 1 and throat die 2 set up relatively, and hemming die 1 is equipped with first die cavity towards throat die 2 one side, first die cavity bottom is equipped with the turn-up profiled groove, and throat die 2 is equipped with the second die cavity towards 1 one side of hemming die, second die cavity inner wall is equipped with the stair structure of annular extension, be equipped with the throat profile of slope setting on the stair structure.
This embodiment still provides a manufacturing technology of automobile decoration tail larynx based on foretell automobile decoration tail larynx's forming die realization, in the course of working, with pipe fitting cutting shaping stock, then put into the stock after the cutting in the forming die for the turn-up end of stock is located the first die cavity of turn-up die 1, and the throat end of stock is located the second die cavity of throat die 2, then drives turn-up die 1 and throat die 2 relative movement compound die, obtains the automobile decoration tail larynx that both ends formed turn-up and throat respectively.
In the specific forming process, along with the relative movement of the hemming female die and the necking female die, the hemming and the necking are simultaneously formed under the action of a hemming forming groove and a necking forming surface, along with the proceeding of hemming, when the force required by hemming is larger than the force required by necking, the hemming is stopped, only necking forming is carried out, when the necking is completed, the bottom of the necking die abuts against the bottom of a second cavity, the necking is finished, and at the moment, the hemming is continuously carried out along with the continuous downward movement of a hydraulic press, so that the hemming and necking processing of products are realized; in the curling process, the inner wall of the first cavity supports the pipe wall to prevent the pipe wall from deforming.
