Processing equipment for horn mouth of metal tube

The invention provides processing equipment for a horn mouth of a metal tube. The processing equipment comprises a fixing device used for clamping and fixing a metal tube, a throat punch used for necking certain end part of the metal tube, a flaring punch used for flaring and forming another end of the metal tube, wherein the front part of the fixed device is provided with a tapered slot which is exposed at the front end of the metal tube; the throat punch is provided with an arc slot, the diameter of the arc slot is not less than the outer diameter of the metal tube, the front end of the flaring punch is coaxially provided with a flanging section and a flaring section from front to back, the flanging section is a forwards protruding tip, and the flaring section is a conical platform matched with the tapered slot. Compared with the prior art, according to the processing equipment provided by the invention, the parts can be greatly reduced, the process of flanging and flaring and forming can be completed by the flaring punch, the processing procedures can be shortened, the production efficiency can be greatly improved, and the reject ratio can be reduced.
