Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum flat tube production, and particularly relates to an anti-adhesion device for aluminum flat tube production. Background Art

[0002] Aluminum flat tube is a long thin-walled tubular structure made of aluminum alloy material, with a flat cross-section (usually rectangular or approximately rectangular), and has the characteristics of light weight, high strength, good corrosion resistance and smooth surface. The existing anti-adhesion device for aluminum flat tube production cools down the fixed mold when extruding the aluminum flat tube, and the spring module drives the aluminum flat tube to be ejected after forming. However, after long-term use, the spring rebound force will decrease, which may affect the anti-adhesion of aluminum flat tube production.

[0003] For example, the utility model with announcement number CN217165977U discloses an anti-adhesion device for online production of aluminum flat tubes, and the extrusion anti-adhesion structure includes: a fixed mold, two ejection springs, two telescopic rods, two limit columns, a first movable seat, a refrigeration cycle component, a plurality of guide columns and a movable mold component; the fixed mold is installed on the top of the base, a rectangular groove is provided in the middle part of the fixed mold, the bottom of the two ejection springs is connected to the inner wall of the rectangular groove, the two telescopic rods are arranged inside the two ejection springs, the two limit columns are respectively installed on both sides of the inside of the rectangular groove, the first movable seat is installed on the top of the two ejection springs, the refrigeration cycle component is arranged on one side of the fixed mold, and the refrigeration cycle The ring assembly is connected to the first movable seat, a number of guide columns are installed on the top of the base, and the movable mold assembly is arranged on the upper side of the guide columns. In the technical solution of this patent, the bottom of the aluminum flat tube is cooled down by the refrigeration cycle assembly when the aluminum flat tube is extruded, thereby avoiding adhesion caused by high temperature. After the aluminum flat tube is formed, the first movable seat is ejected upward by the rebound force of the ejection spring, which can effectively avoid the aluminum flat tube from sticking to the inner wall of the fixed mold. However, in actual use, the rebound force of the spring will decrease during the long-term reciprocating rebound process, thereby reducing the ejection force of the first movable seat, which may affect the anti-adhesion of the aluminum flat tube production.
