Description

Technical Field

[0001] This utility model belongs to the technical field of aluminum profile production equipment, and in particular relates to an aging heat treatment device for high-strength aluminum profiles. Background Technology

[0002] Aging furnaces for aluminum profiles are key heat treatment equipment in aluminum alloy processing. Their main function is to alter the internal structure of the material through precisely controlled temperature and time processes. For high-strength aluminum profiles, aging treatment is particularly crucial, and its effects are mainly reflected in the following aspects: For extruded high-strength aluminum profiles (which have relatively low hardness), aging treatment significantly improves strength, hardness, and wear resistance by promoting the decomposition of solid solution and the precipitation of strengthening phases, enabling them to meet the requirements of high-load applications. The internal stress generated during quenching can easily lead to profile deformation or cracking; aging treatment can effectively release stress and stabilize shape and dimensions.

[0003] Chinese utility model patent CN222524634U, entitled "A Novel Aging Furnace for Aluminum Profile Processing," discloses the following: It includes an aging furnace body, with a cover door rotatably connected to one side of the furnace body. Two cover doors are symmetrically arranged. Two guide rails are fixedly connected to the inner side of the furnace body. After opening the cover door, the support and tray are pulled out of the furnace body using rollers. The aluminum profile material is placed on top of the tray. The pressure plate is lifted by holding the handle and inserted into the outer side of each sliding rod. The pressure plate slides down naturally under gravity. Then, the contacts at the bottom of the telescopic rods contact the top of the aluminum profile material above the tray for pressing and limiting. The tray is then pushed into the furnace body by the rollers. The pressure plate is lifted again by holding the handle and removed from the furnace body. The cover door is closed for processing. This effectively reduces the shaking amplitude generated during the process of pushing the aluminum profile material into the furnace body, effectively ensuring the stability of the material.

[0004] However, the aforementioned aging furnace has the following drawbacks:

[0005] ① When using this aging furnace, the aluminum profiles are placed on a tray, but the tray is a single layer and can only hold a limited number of aluminum profiles;

[0006] ② The aging furnace is placed on a tray and pressed and limited by a pressure plate. The tray is sent into the aging furnace and then the pressure plate is removed. The operation is cumbersome. Moreover, when the aging treatment is completed, the aluminum profiles on the tray are not limited when they are taken out, and there is a risk of them falling out during the process of taking out the furnace body.

[0007] Therefore, there is an urgent need for a high-strength aluminum profile aging heat treatment device to solve the above-mentioned technical problems. Utility Model Content

[0008] The purpose of this invention is to overcome the existing technical problems and provide a high-strength aluminum profile aging heat treatment device.

[0009] To achieve the above objectives, this utility model is implemented according to the following technical solution:

[0010] A high-strength aluminum profile aging heat treatment device includes an aging furnace and a movable support for placing the aluminum profile; the aging furnace is provided with a cuboid heat treatment chamber; the movable support can be placed in the heat treatment chamber; the movable support includes a base plate, four supporting threaded columns, multiple placement hole plates, movable wheels, multiple limiting columns, and multiple limiting nuts;

[0011] The base plate and the placement hole plate are rectangular plates of the same size; four moving wheels are arranged in a rectangular pattern on the bottom of the base plate, and a support threaded post is fixedly installed at each of the four corners of the upper surface of the base plate; multiple placement hole plates are detachably fixedly installed on the four support threaded posts from bottom to top.

[0012] The perforated plate has multiple circular through holes arranged in a matrix;

[0013] The limiting post is an integral structure, consisting of a column, a frustum-shaped limiting part, and a screw from top to bottom. The diameter of the lower end face of the limiting part is larger than the inner diameter of the circular through hole, and the outer diameter of the screw matches the inner diameter of the circular through hole. The screw can be inserted into the circular through hole and is detachably connected to the placement plate through the limiting nut.

[0014] Preferably, support nuts are threaded onto the support threaded posts located on the upper and lower sides of the placement hole plate.

[0015] The aging furnace used in this invention is existing technology; specifically, an aging furnace with hot air circulation can be used.

[0016] During the process of moving the support frame into or out of the aging furnace, the displacement mainly occurs on the front, back, left, and right sides. Therefore, the aluminum profile needs to be restricted in these directions. In use, this invention allows for the creation of corresponding areas on a perforated plate using limiting posts, based on the shape and size of the aluminum profile. The aluminum profile is then placed within these areas, effectively limiting its movement. Therefore, it is applicable to various aluminum profiles of different shapes and sizes. Specifically, for long, narrow aluminum profiles, due to their length, a few limiting posts can be spaced apart on the left and right sides, while several more limiting posts can be closely spaced on the front and back sides, as long as the aluminum profile does not move significantly within the corresponding areas. The height of the limiting posts can be set according to actual usage requirements.

[0017] The placement plate of this utility model is detachably and fixedly connected to the support nut and the support threaded post, so the spacing between the placement plates is adjustable.

[0018] This invention is applicable to various aluminum profiles of different shapes and sizes, making it more flexible in use; the movable bracket is equipped with multiple placement holes, which can accommodate more aluminum profiles.

[0019] Preferably, the movable support further includes a limiting plate assembly; the limiting plate assembly includes a limiting plate, two pressing plates, and a locking nut; the left and right sides of the limiting plate are provided with connecting edges, and the upper end face of the pressing plate is provided with a locking screw; the connecting edges are provided with connecting holes for the locking screw to pass through.

[0020] The limiting plate is set on the upper end face of the front and rear sides of the placement plate, and the clamping plate is located on the lower side of the placement plate; the locking screw passes through the connecting hole from bottom to top and is threaded with a locking nut. The lower end face of the limiting plate and the upper end face of the clamping plate clamp the placement plate.

[0021] The limiting plate assembly primarily restricts the aluminum profile placed on the perforated plate from significant movement in the front-to-back direction; the limiting plate assembly also makes disassembly and assembly more convenient and quick. When used in conjunction with limiting posts, the limiting plate assembly can more quickly create a zone that limits the movement of the aluminum profile.

[0022] Preferably, the lower end face of the limiting plate and the upper end face of the pressing plate are both provided with an elastic layer.

[0023] The addition of an elastic layer increases the clamping force between the limiting plate and the pressure plate, thereby increasing the clamping firmness of the limiting plate assembly.

[0024] Preferably, a rectangular hole is provided at the center of the base plate, and a grid plate is fixedly installed inside the rectangular hole.

[0025] When the aging furnace used has hot air circulation, the grating plate is set to facilitate the flow of hot air, so that the aluminum profile can be heated evenly during aging heat treatment.

[0026] Preferably, a roller is fixedly provided on the front side of the left end face, the rear side of the left end face, the front side of the right end face, and the rear side of the right end face of the base plate.

[0027] The rollers are mainly used to limit the movement and prevent the moving support frame from contacting the inner wall of the aging furnace, which would cause the aluminum profile on the moving support frame to become too hot locally and affect the quality of the aging heat treatment.

[0028] Components not specified in this invention are all made using conventional methods in the field. Those skilled in the art can select their models and installation methods according to actual usage needs, and clearly understand how to install and control them. They will not be described in detail here.

[0029] This utility model achieves the following beneficial effects:

[0030] This utility model has a simple structure and is easy to operate. The placement plate of this utility model is detachably fixedly connected by a support nut and a support threaded post, so the spacing between the placement plates is adjustable. Multiple placement plates can be set, which can support a large number of aluminum profiles. The position of aluminum profiles of different shapes and sizes on the placement plate can be restricted, making it more flexible to use. The movable bracket prevents the aluminum profiles from shifting too much or falling off during use, and also prevents the aluminum profiles from stacking. The spaced aluminum profiles can also be heated evenly during aging heat treatment, ensuring the quality of aging heat treatment. Attached Figure Description
