Description

TECHNICAL FIELD

[0001] The utility model relates to aluminium profile processing equipment technology, concretely is a kind of aluminium profile extruding machine cooling device. BACKGROUND

[0002] The density of aluminium profile is about 1 / 3 of the density of steel, copper or brass, and aluminium can show excellent corrosion resistance under most environmental conditions, including in air, water, petroleum chemistry and many chemical systems, so it is widely used in building construction. Most aluminium profiles are formed by extrusion. The aluminium profile coming out of the extruder needs to be cooled to improve its mechanical strength and performance, as it has a high temperature, to facilitate the next processing or treatment.

[0003] The traditional air cooling structure is to set multiple fans along the length direction of the conveyor on the top or bottom of the conveying roller table to blow air to the aluminium profile. Since the distance between the fan outlet and the aluminium profile is far, the wind power loss during blowing is large. Therefore, some machines connect a straight pipe to one fan, and a plurality of openings are arranged below the straight pipe, and each opening is provided with a cooling pipe to reduce the distance between the cooling pipe and the aluminium profile. However, in this cooling method, the relative distance between different cooling pipes and the fan is different, so the wind power of the final blowing is also different, resulting in different cooling effects on different parts of the aluminium profile, and the uniformity of the aluminium profile during cooling is poor. Therefore, we propose an aluminium profile extruder cooling device to solve the above problems. SUMMARY

[0004] In view of the deficiencies in the prior art, the present utility model provides an aluminium profile extruder cooling device to solve the problems raised in the background art.

A wind diffusing pipe is arranged on the front and back sides of the wind diffusing ring. A corrugated hose is in communication between the wind diffusing pipe and one of the cooling pipes. An air inlet pipe is fixedly connected to the top of the wind diffusing ring. The air inlet pipe is in communication with the output end of the external fan.
