Problems solved by technology
[0004] However, the row-type fan blowing cooling method in the prior art can only guarantee a low extrusion speed. In the extrusion production process of aluminum alloy or magnesium alloy, the instantaneous extrusion speed is often too fast, resulting in extruded Aluminum alloy or magnesium alloy cannot be cooled rapidly, the excessive growth of metal grains inside the profile will cause the mechanical properties to decline, the surface will be excessively oxidized, and even burn. The speed of cooling metal profiles in the prior art is relatively slow

Embodiment Construction
[0016] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.
[0017] figure 1 It is a structural schematic diagram of an embodiment of the composite cooling device for metal extrusion of the present invention. Such as figure 1 As shown, the composite cooling device for metal extrusion in this embodiment includes: an annular hollow sleeve 1 and a hollow barrel 2, which respectively cool the high-temperature extruded from the extruder through indirect cooling and direct cooling. The extruded profile 4 undergoes rapid cooling. The specific introduction is as follows:
[0018] The inner wall 12 of the annular hollow sleeve 1 forms the first cooling channel for cooling the extruded profile 4, and an accommodation cavity 15 is provided between the outer wall 11 and the inner wall 12 of the annular hollow sleeve 1, and a cooling chamber 15 is provided in the accommodation cavity 15. Coolant...

The embodiment of the invention provides a composite cooling device and system for metal extrusion, which comprises an annular hollow sleeve and a hollow barrel, wherein an inner wall of the annular hollow sleeve forms a first cooling channel for cooling the extruded section, a containing cavity is arranged between an outer wall and the inner wall of the annular hollow sleeve, and cooling liquid for cooling the extruded section is filled in the containing cavity; a charging opening is arranged on a charging end surface of the hollow barrel, the charging opening is butted with the first cooling channel formed by the annular hollow sleeve, a discharging opening opposite to the charging opening is arranged on a discharging end surface of the hollow barrel, and a second cooling channel for cooling the extruded section is formed between the charging opening and the discharging opening; and a spray pipe is also arranged above the second cooling channel in the hollow barrel, and a plurality of spray nozzles for spraying the cooling liquid to the extruded section are arranged on the spray pipe along the direction from the charging opening to the discharging opening. By arranging the annular hollow sleeve and the hollow barrel, the extruded section is quickly cooled, and the cooling speed of the extruded section is improved.
Description
technical field [0001] Embodiments of the present invention relate to cooling technology, in particular to a compound cooling device and system for metal extrusion. Background technique [0002] During the use of metal profiles, in order to meet the requirements of use, it is necessary to extrude the metal profiles through an extrusion machine. When the extruder extrudes the metal profile, the metal profile will generate a lot of heat during the extrusion process, which will increase the temperature of the metal profile extruded by the extruder, which will easily cause excessive oxidation on the surface of the metal profile and internal structure. Extrusion defects such as unevenness will reduce the performance of the metal. [0003] In the prior art, when extruding an aluminum alloy or a magnesium alloy, the extruder is usually cooled by compressed air. For example, the air blowing cooling method of the row fan is adopted, and the cold air is blown to the surface of the e...
