Description

Aluminum pipe extrusion system Technical Field The invention relates to the technical field of aluminum pipe forming, in particular to an aluminum pipe extrusion system. Background The aluminum pipe extrusion system is an aluminum pipe forming device, and can form and output the formed aluminum pipe in the cylindrical outer die by extruding high-temperature aluminum ingots. The shape and the thickness of aluminum pipe are decided by the exit end mould and the entry end mould of tube-shape external mold both sides, because the exit end mould adopts the form of detachable connection to connect in one side of tube-shape external mold in the prior art, consequently, when the aluminum pipe of shaping different shapes, or when the exit end mould damages, all need change exit end mould, this process is mostly carried out manually, and the temperature of used exit end mould often is higher, not only inconvenient change exit end mould, has still reduced aluminum pipe shaping efficiency. Disclosure of Invention Technical problem to be solved In view of the above-mentioned drawbacks and disadvantages of the prior art, the present invention provides an aluminum pipe extrusion system, which solves the technical problems in the prior art that when aluminum pipes of different shapes are formed or when outlet end dies are damaged, the outlet end dies need to be replaced, the process is mostly performed manually, the temperature of the used outlet end dies is often high, the replacement of the outlet end dies is inconvenient, and the forming efficiency of the aluminum pipes is reduced. Technical proposal In order to achieve the above purpose, the main technical scheme adopted by the invention comprises the following steps: The invention provides an aluminum pipe extrusion system which comprises a cylindrical outer die, a first disc body and a plurality of outlet end dies, wherein the cylindrical outer die can slide along an axis of the cylindrical outer die, the two ends of the axial direction of the cylindrical outer die are provided with a first opening and a second opening, the first disc body is positioned on one side of the cylindrical outer die, the outlet end dies are hollow and are symmetrically distributed on the first disc body along the center of the axis of the first disc body, one or more outlet end dies form one model or a plurality of groups of different models, the outlet end dies are provided with first matching parts, the first matching parts can extend into the cylindrical outer die from the second opening, and the first disc body can rotate so that the position of each outlet end die can be matched with the position of the cylindrical outer die, and then when the cylindrical outer die slides towards the direction close to the first disc body, the first matching parts can be inserted into the cylindrical outer die from the first opening. In the technical scheme, a plurality of outlet end dies are all arranged on a first disc body, a first matching part of the outlet end dies can be matched with a cylindrical outer die to realize aluminum pipe forming, when the first disc body rotates, different outlet end dies can be made to correspond to the cylindrical outer die, one or more outlet end dies are in a group, each group of outlet end dies are arranged to be the same type of outlet end dies, when one certain type of outlet end dies are damaged, other intact outlet end dies in the same group can be put into use, and when another aluminum pipe with different shapes needs to be formed, one outlet end die of the corresponding group of outlet end dies can be put into use, so that the quick replacement of the outlet end dies can be realized, and the aluminum pipe forming efficiency is improved. When the position of one outlet end die corresponds to the position of the cylindrical outer die, the first matching part always gradually extends into the cylindrical outer die from the first opening in the process that the cylindrical outer die slides towards the direction close to the first disc body, so that the first matching part becomes the outlet side end die of the aluminum pipe.
