Problems solved by technology
[0002] In the conventional forward extrusion device, due to the relative movement between the billet and the inner wall of the extrusion chamber, the extrusion chamber has a great friction force on the billet, which largely offsets the forward extrusion At the same time, there is a large pressure surplus and shrinkage in the forward extrusion.
In reverse extrusion, there is a plug at the end of the extrusion rod to drive the extrusion chamber and the billet to advance together, and there is no friction between the extrusion chamber and the billet. Although the extrusion force is not offset, the extrusion chamber will The metal of the wall still flows slowly and is prone to shrinkage at the end of the tube extrusion

technical field [0001] The invention belongs to the field of metallurgical equipment, and relates to an extrusion technology in the extrusion process of an aluminum extrusion machine, specifically an extrusion device and an extrusion method for an extrusion chamber of an aluminum extrusion machine. Background technique [0002] In the conventional forward extrusion device, due to the relative movement between the billet and the inner wall of the extrusion chamber, the extrusion chamber has a great friction force on the billet, which largely offsets the forward extrusion At the same time, there is a large excess pressure and shrinkage in the forward extrusion. In reverse extrusion, there is a plug at the end of the extrusion rod to drive the extrusion chamber and the billet to advance together, and there is no friction between the extrusion chamber and the billet. Although the extrusion force is not offset, the extrusion chamber will The wall metal still flows slowly and ten...
