Description

TECHNICAL FIELD

[0001] The utility model relates to aluminium profile straightening technical field, especially high straightness aluminium profile heat preservation straightening device. BACKGROUND

[0002] The straightening equipment of aluminium profile is mainly used for correcting the bending, distortion or other deformation of aluminium profile in the production process due to extrusion, heat treatment and other processes. The straightening equipment ensures the straightness and size accuracy of the profile by applying mechanical force. For various lengths and cross-sectional shapes of aluminium profile, a more widely used roller straightening machine is generally used to straighten the aluminium profile. The roller straightening machine extrudes the profile through straightening rollers to change the straightness.

[0003] In the existing aluminium profile straightening process, the aluminium profile can be heated appropriately to better adapt to the force of the straightening equipment, thereby achieving high straightness straightening of the aluminium profile. However, the distance of the aluminium profile from being heated to the straightening machine is relatively long, which reduces the temperature of the aluminium profile during heating and straightening, thereby affecting the straightening plasticity of the aluminium profile in the straightening machine. Therefore, we propose a high straightness aluminium profile heat preservation straightening device. SUMMARY

[0004] The main purpose of the utility model is to provide a high straightness aluminium profile heat preservation straightening device. The heat preservation mechanism is provided at the introduction table on one side of the feeding end of the straightening machine body. The heat preservation mechanism forms a hot air supply through the flange connection of the hot air blower and the L-shaped heat guide pipe. The main guide box with a heat preservation inner lining layer, the outer connecting pipe and the metal corrugated pipe construct a full-path heat preservation hot space. This effectively reduces the heat loss of the aluminium profile during transportation after straightening and heating, ensures that the aluminium profile still maintains the best heat deformation temperature when entering the straightening machine, and significantly improves the straightness accuracy of the aluminium profile after straightening. This can effectively solve the problems in the background technology.
