[0019] Please refer to Figures 1-8 The application provides a technical solution: a multi-parameter self-adaptive control extrusion device for aluminum profile production, which comprises a protective shell 1, an extrusion unit is arranged in the protective shell 1, the protective shell 1 is provided with multiple groups and can be vertically spliced, a feeding assembly is arranged on the top protective shell 1, the feeding assembly can push the aluminum material to vertically move downward, and the extrusion unit comprises: an extrusion die 8, the extrusion die 8 is provided with an extrusion groove 7, multiple groups of the extrusion die 8 are vertically distributed, and the hole diameters of the upper extrusion grooves 7 gradually decrease from top to bottom, the extrusion die 8 is internally provided with a liquid cavity 801, and a temperature sensor is fixedly arranged in the liquid cavity 801; a heat dissipation pipe 11, the heat dissipation pipe 11 is provided with multiple groups and is equidistantly connected in the extrusion die 8, the heat dissipation pipe 11 is provided with a flow distribution assembly, and the flow distribution assembly can control the flow direction of the liquid according to the liquid temperature in the liquid cavity 801; a supporting unit, the supporting unit is supported around the outside of the heat dissipation pipe 11 and the extrusion die 8, and a horizontal monitoring system is arranged in the supporting unit, and the horizontal monitoring system can detect the levelness of the extrusion die 8.

[0020] During operation, the derailed multiple extrusion units in the present invention are vertically distributed up and down, and the extrusion grooves of the extrusion dies inside them gradually decrease. The apertures of the extrusion grooves of the multiple extrusion dies decrease from top to bottom in sequence, realizing gradient extrusion and reducing the single deformation to complete the extrusion molding of the aluminum material. During the extrusion of the aluminum material, frictional heat is generated, resulting in excessively high local temperature of the mold, which easily affects the surface quality of the profile and the life of the mold. The present invention introduces a low-temperature liquid into the liquid cavity in the extrusion mold, and absorbs heat from the mold surface due to friction, thereby preventing the local temperature of the mold from being too high, increasing the service life of the mold, and reducing the possibility of oxidation of the aluminum material during processing. The temperature sensor in the liquid cavity detects the liquid about to be discharged from the liquid cavity. When its temperature is higher than the set value, the diversion component drives the liquid back to the refrigeration equipment until the liquid cools down and flows back into the liquid cavity again. When the temperature of the discharged liquid is lower than the set value, the diversion component drives the liquid to flow into the next extrusion unit, and the next group of extrusion dies is cooled by this heat-absorbing unsaturated liquid, thereby reducing the waste of refrigerant and ensuring the full utilization of resources. In the present invention, aluminum extrusion molding is performed through multiple groups of vertically distributed extrusion units. In order to prevent the horizontality of the mold from being easily affected during multi-pass extrusion, which may lead to deviation in the cross-sectional size of the profile, the horizontality of the extrusion mold in the extrusion unit is always monitored by a horizontal monitoring system, and its horizontality is adjusted in real time by a support unit to ensure that the multi-pass mold is always parallel to the ground, thereby improving the quality of the aluminum processing products.
