[0036] Metal profiles are widely used in the fields of building, transportation, electronics, aerospace, etc., and the extrusion forming of metal profiles is an important method of pressure processing using metal plastic forming principle, and the metal blank is processed into pipe, bar and other profiles by extrusion. In the extrusion forming process of metal profiles, the extrusion forming device mainly includes a die, an extrusion rod and a driving mechanism, the die is usually provided with a sleeve on one side, the driving mechanism drives the extrusion rod to extrude the metal blank to the die, so that the metal blank passes through the die to output the metal profile product. The extrusion forming device has insufficient uniformity of extrusion effect, stress concentration in the extrusion process, low extrusion forming quality, high extrusion loss and short service life of the device.

[0037] The extrusion forming device in the prior art extrudes the metal blank in a one-way extrusion manner, which can cause uneven flow of the metal blank during the extrusion process, easily cause internal stress concentration of the formed component, easily affect the mechanical properties and surface quality of the product, in addition, the extrusion forming manner can also cause structural wear, and long-time wear can also cause size deviation and surface defects of the extrusion forming, and the extrusion stroke is long, the extrusion force is high, the production efficiency is low, and the working burden of the driving mechanism is large. With the continuous improvement of the performance and quality requirements of modern industry on aluminum profiles, an extrusion forming device with uniform extrusion effect is urgently needed to solve the above technical problems and meet the needs of high-end manufacturing fields.

[0042] a sleeve assembly 300 comprising an extrusion cylinder 310 and a second translation driving module 330, the extrusion cylinder 310 being connected to the second translation driving module 330, the extrusion cylinder 310 being located on one side of the extrusion die 220, the extrusion cylinder 310 being provided with an extrusion channel 320 opposite to the extrusion die cavity 221, the second translation driving module 330 being connected to the positioning seat 210, and the second translation driving module 330 being used to drive the extrusion cylinder 310 to translate relative to the positioning seat 210 along a second extrusion direction, the first extrusion direction and the second extrusion direction being coaxial and opposite, i.e., the first extrusion direction and the second extrusion direction are located on the same straight line and are opposite in direction, wherein the first extrusion direction is directed from the extrusion die 220 to the extrusion cylinder 310, and correspondingly, the second extrusion direction is directed from the extrusion cylinder 310 to the extrusion die 220;

[0043] The extrusion assembly 400 includes a push rod 410 and a third translation drive module 420. The push rod 410 is connected to the third translation drive module 420 and is located on the side of the extrusion die 220 near the extrusion cylinder 310. The push rod 410 is directly opposite the extrusion channel 320 and matches the extrusion channel 320. The push rod 410 is used to push and extrude the metal billet in the channel. The third translation drive module 420 is connected to the frame 100 and is used to drive the push rod 410 to translate along the second extrusion direction so that the extrusion rod enters the extrusion cylinder 310 and cooperates with the extrusion die 220 to compress the metal billet in the extrusion cylinder.
