Description

Technical Field

[0001] The invention relates to the field of aluminum profile quenching, in particular to an air-cooling quenching device for aluminum profiles. Background Art

[0002] During the high-temperature extrusion process of aluminum profiles, a supersaturated solid solution will be formed, and then the supersaturated solid solution will be reduced to room temperature by rapid cooling. At this time, the plasticity of the material is relatively high, and the straightening process can be carried out after quenching. The quenching process is divided into online quenching and offline quenching. Online quenching uses the high temperature during extrusion for solid solution, and then uses air cooling or water cooling to quickly reduce the temperature of the aluminum profile to room temperature, thereby obtaining certain organizational properties. This is a common quenching method for aluminum profiles.

[0003] In the production process of household aluminum profiles, online air cooling is often used for quenching. The specific working principle is as follows: the extruded aluminum profile will enter the conveyor line, which is generally transported by rollers. At this time, the upper air-cooling hood descends to cover the aluminum profile, and then the aluminum profile is cooled by blowing air through a number of blowing devices arranged on the top of the air-cooling hood. The blowing devices are distributed along the aluminum profile.

[0004] The above-mentioned related technologies have the following defects: since the blowing device is only located directly above the aluminum profile, the area in which the aluminum profile is in direct contact with the cooling airflow is small, which seriously affects the cooling efficiency; at the same time, the distance between the air outlets of adjacent blowing devices is large, which further leads to a reduction in the area in which the aluminum profile is in direct contact with the cooling airflow, further affecting the cooling efficiency. Summary of the invention

[0005] In order to solve the technical problem of improving the cooling efficiency of aluminum profiles, the present invention provides an air-cooling quenching device for aluminum profiles.

[0006] The present invention provides an air-cooling quenching device for aluminum profiles that adopts the following technical solution:

[0007] A wind-cooled quenching device for aluminum profiles, comprising an extruder and a wind-cooled quenching device body arranged at the discharge side of the extruder; the wind-cooled quenching device body comprises a bracket, a lifting device and a wind-cooled quenching device; the lifting device and the wind-cooled quenching device are both arranged on the bracket; the lifting device is used to drive the horizontal aluminum profile to rise and fall vertically; the wind-cooled quenching device is used to blow air to cool the horizontal aluminum profile; the wind-cooled quenching device comprises a pair of wind-cooled quenching mechanisms; the wind-cooled quenching mechanism comprises a horizontal driving component and a wind-cooled quenching component; the horizontal driving component is used to drive the wind-cooled quenching The quenching assembly moves horizontally; the air-cooled quenching assembly includes a plurality of air guide tubes evenly distributed in the horizontal direction; the inner end of the air guide tube is formed with a plurality of radially arranged air nozzles evenly distributed; when a pair of the air-cooled quenching assemblies abut against each other, all the air guide tubes are combined into a pair of coaxial cylindrical spiral tubes with the same diameter and pitch, and one cylindrical spiral tube is located in the gap of the other cylindrical spiral tube; the axial direction of the cylindrical spiral tube is parallel to the length direction of the aluminum profile; the air nozzles are evenly distributed along the same cylindrical spiral tube; one end of the cylindrical spiral tube is sealed, and the other end is connected to an external air blowing device.

[0008] By adopting the above technical scheme, the aluminum profile is extruded from the extruder and enters the frame, and then the lifting device drives the aluminum profile to rise vertically. In this process, it vertically passes through the gap between a pair of air-cooled quenching components, and then a pair of horizontal driving components drive a pair of air-cooled quenching components to approach each other until they are close together. At this time, all the air guide tubes form a pair of cylindrical spiral tubes. At this time, the aluminum profile is located at the axis of the pair of cylindrical spiral tubes, and then a pair of air blowing devices are started to supply air into the pair of cylindrical spiral tubes. Finally, the air flow is ejected from the air nozzle to cool the aluminum profile. Since the aluminum profile is located at the axis of the pair of cylindrical spiral tubes, the direct contact area between the aluminum profile and the air flow is greatly increased, thereby improving the cooling efficiency of the aluminum profile.

[0009] Optionally, adjacent air guide tubes are in contact with each other.

[0010] By adopting the above technical solution, the air nozzles are distributed more densely, thereby further increasing the direct contact area between the aluminum profile and the airflow, and improving the cooling efficiency of the aluminum profile.

[0011] Optionally, when a pair of the air-cooled quenching components abut against each other, the connection of the air duct is sealed.

[0012] By adopting the above technical solution, the sealing performance of the cylindrical spiral tube composed of the air guide tube is improved, which is conducive to quickly increasing the pressure in the cylindrical spiral tube, making the air flow ejected from the air nozzle faster, thereby improving the cooling efficiency of the aluminum profile.

[0013] Optionally, the air-cooled quenching assembly further includes a semicircular outer support frame; the inner diameter of the outer support frame is the same as the outer diameter of the cylindrical spiral tube and the air guide tube is fixed on the inner cylindrical surface of the outer support frame.

[0014] By adopting the above technical solution, the existence of the external support frame makes the installation of the air guide tube convenient, and is also conducive to the subsequent rapid combination of the cylindrical spiral tube, thereby improving the cooling efficiency of the aluminum profile

[0015] Optionally, the lifting device includes a pair of lifting mechanisms distributed along the length of the aluminum profile; the pair of lifting mechanisms are respectively located on the outside of the air-cooled quenching assembly; the lifting mechanism includes a lifting drive assembly and an end support assembly; the lifting drive assembly is used to drive the end support assembly to vertically lift and lower.

[0016] By adopting the above technical solution, a pair of end support assemblies support the two ends of the aluminum profile so that the aluminum profile is suspended at the axis of the cylindrical spiral tube, thereby increasing the direct contact area between the aluminum profile and the airflow and improving the cooling efficiency of the aluminum profile.

[0017] Optionally, a translation support is provided on the end support assembly; a pair of the translation support is located between a pair of the end support assemblies; the translation support is used to support the bottom of the aluminum profile; a pair of translation drive devices are provided on the bracket and the pair of translation drive devices are distributed parallel to the axial direction of the cylindrical spiral tube; the translation drive device includes a driving support frame and a translation drive mechanism arranged on the driving support frame; a pair of the end support assemblies are located between a pair of the translation drive devices; the translation drive mechanism is used to drive the corresponding translation support members to move horizontally in the cylindrical spiral tube.

[0018] By adopting the above technical solution, during the cooling process, a pair of translation drive mechanisms respectively drive a pair of translation support members to move horizontally, thereby supporting the aluminum profile. This ensures that the aluminum profile is suspended in the air while reducing the deformation of the aluminum profile due to its own weight.

[0019] Optionally, the translation support member includes a rotatable and horizontally arranged translation support roller; the axial direction of the translation support roller is perpendicular to the length direction of the aluminum profile.

[0020] By adopting the above technical solution, the translation support roller can support the aluminum profile while the rotatable translation support roller can avoid causing damage to the aluminum profile during the movement.

[0021] Optionally, the translation support member also includes a pair of translation support plates horizontally inserted on the end support assembly; the translation support roller is rotatably connected to the pair of translation support plates; the translation drive mechanism includes a translation drive frame and a translation drive assembly that drives the translation drive frame to move horizontally; the translation drive frame includes a pair of rectangular translation drive plates parallel to the axial direction of the cylindrical spiral tube; a rectangular groove-shaped drive slot is formed on the end surface of the translation support plate away from the translation support roller for horizontal insertion of the translation drive plate; an electromagnet is provided at one end of the translation drive plate close to the drive slot; and a metal plate adsorbed by the electromagnet is provided at the inner end of the drive slot.

[0022] By adopting the above technical solution, the translation drive assembly drives the translation drive frame to move horizontally, and a pair of translation drive plates of the translation drive frame are inserted into the drive slots of a pair of translation support plates. At this time, the electromagnet generates magnetism to attract the metal plates in the drive slots, so that as the translation drive frame moves further, the pair of translation support plates also move accordingly without accidentally falling off, thereby stably realizing the role of the translation support roller in dragging the aluminum profile.

[0023] Optionally, an exhaust device is provided on the driving support frame; a pair of exhaust devices are distributed along the axial direction of the cylindrical spiral tube; the exhaust device is used to discharge the heat generated by quenching from the middle of the cylindrical spiral tube.

[0024] By adopting the above technical solution, a large amount of heat will be generated during the air-cooling quenching process. If the heat is not discharged in time, it will cause heat accumulation and reduce the cooling speed of the aluminum profile. A pair of exhaust devices can discharge the heat generated during the air-cooling quenching process in time, thereby improving the cooling efficiency of the aluminum profile.

[0025] Optionally, a limit assembly is provided on the end support assembly; the limit assembly is used to limit the translation support member on the end support assembly.

[0026] By adopting the above technical solution, the limiting assembly can limit the translation support member to a fixed position on the end support assembly, thereby facilitating the subsequent translation drive mechanism to drive the translation support member to translate.

[0027] In summary, the beneficial effects of the present invention are:

[0028] 1. Increase the direct contact area between the aluminum profile and the airflow, thereby improving the cooling efficiency of the aluminum profile.

[0029] 2. While ensuring the aluminum profile is suspended, reduce the deformation of the aluminum profile caused by its own weight. BRIEF DESCRIPTION OF THE DRAWINGS
