Description

TECHNICAL FIELD

[0001] The utility model relates to aluminium alloy processing forming technical field, concretely relates to a flatness shaping device of thin -walled cavity aluminium alloy section bar. BACKGROUND

[0002] Aluminum profile is formed by hot extrusion and is an industrial material with various structures, has the characteristics of light weight, corrosion resistance, high recovery rate, and is widely used in green construction, transportation, mechanical equipment and power engineering fields. With the trend of "double carbon", aluminum consumption is undergoing structural changes. Thin-walled cavity aluminum alloy profiles are widely developed in various industries due to their light weight, high strength and other characteristics. At the same time, the inner cavity size and the flatness of the side wall of the thin-walled cavity profile are important control dimensions. In the extrusion process, in order to ensure high strength and toughness, extremely high quenching temperature and rapid cooling quenching are required, which makes it difficult to accurately control the flatness size of the four side walls of the cavity profile. If the profile plane produces a protrusion, a roller shaping can be used for roller shaping to make the product qualified. But if the profile plane produces a depression, it is difficult to use the above method for shaping. At this time, the size exceeds the customer's requirements, so it can only be scrapped, causing great loss to the enterprise.

[0003] At present, the patent application number CN202020968815.X discloses an aluminum profile shaping equipment, which comprises a frame body for placing aluminum profiles, a telescopic cylinder, a shaping block and a supporting plate. The frame body comprises two long strip-shaped frames and left and right connecting frames arranged at the two ends of the long strip-shaped frames. The lower surfaces of the two long strip-shaped frames are inwardly extended to form limiting grooves. The telescopic cylinder is arranged on one side of the frame body. A fixed bearing is clamped on the inner side surface of the right connecting frame. The cylinder rod of the telescopic cylinder extends out of the through hole of the fixed bearing. The supporting plate is movably arranged on the limiting groove. The supporting plate is fixedly installed on the right connecting frame and extends to the left side. The utility model has the advantages of simple structure, easy realization of aluminum profile shaping, improved work efficiency and reduced labor intensity of workers. The patent application number CN201822236567.5 discloses a novel hollow profile shaping tool, which comprises a pressure device and a hydraulic device connected through an oil pressure pipe. The hydraulic device is movable. A guide rod is arranged on the hydraulic device. The hydraulic device can drive the guide rod to move. One end of the guide rod is connected with the hydraulic device. The other end of the guide rod is connected with a stress block. The gap and the collapsed cavity problems in the production process can be effectively solved through the hydraulic equipment and the die, thereby improving the yield. However, the existing technology has the following problems. Firstly, most of the above aluminum alloy profile shaping equipment and methods mainly rely on supporting after filling the profile cavity with the equipment, which is very slow and has poor shaping effect, and the surface flatness of the profile fluctuates unevenly. Secondly, the above method is difficult to operate for long profiles. Thirdly, it is not easy to control the deformation degree of the concave part after the profile is shaped. The aluminum alloy profile has a certain resilience. The existing shaping technology is easy to make the profile plane from concave to convex. At this time, the profile surface that becomes convex needs to be continuously rolled, which reduces the shaping efficiency. In view of the above problems, it is necessary to research and design a novel flatness shaping device for thin-walled cavity aluminum alloy profiles to overcome the problems existing in the shaping of the existing thin-walled cavity aluminum alloy profiles.
