Description

Technical Field

[0001] This invention belongs to the field of metal processing technology, and in particular relates to a heat treatment device for aluminum profile processing. Background Technology

[0002] The heat treatment process for aluminum profiles is a core link in the aluminum alloy processing chain. It mainly includes solutions treatment, aging treatment, and quenching. By precisely controlling the heating temperature, holding time, and cooling rate, the microstructure inside the aluminum alloy can be changed, causing the strengthening phase to precipitate uniformly. This significantly improves the hardness, strength, and corrosion resistance of the aluminum profiles. For aluminum profiles used in aerospace, rail transportation, and high-precision machinery, the quality of heat treatment directly determines the service life and structural safety of the material.

[0003] Existing heat treatment equipment mostly uses fixed clamps for fixing. For irregularly shaped profiles, it is difficult to ensure that their axis is precisely aligned with the center of the cooling spray system. Once the profile is off-center, it will lead to uneven spraying of the cooling medium, causing unilateral shrinkage stress in the profile, which in turn leads to bending deformation. The mechanical strength of aluminum profiles in the high-temperature solution state decreases significantly. Existing heat treatment equipment lacks internal support, which makes hollow or thin-walled profiles prone to cross-sectional collapse or twisting during processing, affecting the product's appearance and dimensional tolerances. Existing heat treatment equipment mostly uses fixed spraying for quenching, resulting in cooling dead corners on the back surface of the profile or in the grooves of complex cross-sections. Inconsistent cooling rates will lead to uneven distribution of precipitated phases, resulting in the finished aluminum profiles failing to meet strength and toughness standards.

Detailed Implementation

[0070] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0071] Please see Figures 1-8The present invention provides a technical solution: a heat treatment equipment for aluminum profile processing, including a processing chamber 1, two doors 2 on one side of the processing chamber 1, a positioning mechanism 3 including multiple contact rollers 306 disposed inside the processing chamber 1, which fix the position of the profile by tightly fitting the multiple contact rollers 306 with the outer wall of the profile at the corresponding position, an inner support mechanism 4 including multiple support plates 407 disposed inside the processing chamber 1, which support the inner wall of the profile with different inner diameters by the synchronous expansion of the multiple support plates 407, and a quenching mechanism 5 including multiple nozzles 513 disposed inside the processing chamber 1, which perform water quenching on the profile by rotating the multiple nozzles 513 around the profile axis.

[0072] The positioning mechanism 3 also includes a support base 301, which is located inside the processing compartment 1; a positioning ring 302, which is located on the top of the support base 301; guide blocks 303, which are located at corresponding positions on the outer walls of both sides of the positioning ring 302; and support frames 304, which are located at corresponding positions on the side walls of the positioning ring 302.

[0073] The positioning mechanism 3 also includes a synchronization plate 305, multiple synchronization plates 305 are respectively located at corresponding positions on the outer walls of both sides of the positioning ring 302, one side of the outer wall of the synchronization plate 305 is rotatably connected to the contact roller 306, a rotating shaft 307, multiple rotating shafts 307 are respectively located at corresponding positions on the outer walls of both sides of the positioning ring 302, a gear 308, the gear 308 is rotatably connected to the rotating shaft 307 at the corresponding position, a rack 309, two racks 309 are embedded at both ends of one side of the outer wall of the synchronization plate 305, and an electric push rod 310, the electric push rod 310 is connected to one side of the outer wall of the support frame 304, and the telescopic part of the electric push rod 310 is connected to the corresponding position on one side of the outer wall of the synchronization plate 305.

[0074] Specifically: Two synchronous plates 305 on the same side of the positioning ring 302 form a group, and the two groups of synchronous plates 305 are perpendicular to each other. One end of the profile is inserted into the processing compartment 1 from the hatch 2, and the other end of the profile passes through the opening in the center of the positioning ring 302. The electric push rod 310 pushes one side of the synchronous plate 305 through the telescopic part. The synchronous plate 305 is slidably connected to the guide block 303. The synchronous plate 305 moves towards the center of the positioning ring 302 along the direction of the guide block 303. The rack 309 meshes with the gear 308. The synchronous plate 305 drives the rack 309 to move synchronously. The rack 309 drives the gear 308 to rotate. The gear 308 drives the other rack 309 to move synchronously. The other rack 309 pulls the other rack on the same side. Synchronous plate 305 causes two synchronous plates 305 on the same side of positioning ring 302 to move synchronously toward the center of positioning ring 302. Synchronous plate 305 drives contact roller 306 to move synchronously. The two contact rollers 306 are tightly attached to the left and right outer walls of the profile respectively. The other set of two synchronous plates 305, driven by electric push rod 310, drives two contact rollers 306 to move from the upper and lower sides toward the center of positioning ring 302 respectively and are tightly attached to the upper and lower outer walls of the profile respectively. The four contact rollers 306 position the profile at the axial position of positioning ring 302 from four directions. The contact rollers 306 and synchronous plate 305 can rotate relative to each other. After the profile is positioned at the axial position of positioning ring 302, it can continue to be inserted inward.

[0075] It should be noted that the electric actuator 310 described above is a new type of linear actuator composed of a motor, an actuator, and a control device. It is an electric drive device that converts the rotational motion of the motor into the linear reciprocating motion of the actuator. This part is well-known technology in the field and will not be described in detail here.

[0076] Please see Figures 4-6 The internal support mechanism 4 also includes a mounting frame 401, which is located on the inner wall of one side of the processing compartment 1, a threaded column 402, the front end of which passes through the top of the mounting frame 401, and a handwheel 403, which is connected to the rear end of the threaded column 402.

[0077] The inner support mechanism 4 also includes a central shaft 404, which is located on one side of the mounting bracket 401. The front end of the threaded column 402 is connected to one end of the central shaft 404. A first sliding seat 405, a plurality of first sliding seats 405 are arranged around the axis of the central shaft 404 on the outer wall of the central shaft 404. A second sliding seat 406, a plurality of second sliding seats 406 are equidistantly arranged on one side of the outer wall of the support plate 407, and the plurality of second sliding seats 406 are slidably connected to the first sliding seat 405 at the corresponding positions.

[0078] The inner support mechanism 4 also includes a sliding frame 408, multiple sliding frames 408 are arranged around the axis of the mounting frame 401 at the bottom of the mounting frame 401, and a slider 409 is arranged on the outer wall of one side of the support plate 407. The slider 409 is slidably connected to the sliding frame 408 at the corresponding position.

[0079] Specifically: the positioning ring 302 coincides with the axis of the central shaft 404; the external thread on the outer wall of the threaded column 402 meshes with the internal thread on the inner wall of the mounting bracket 401; rotating the handwheel 403 causes the threaded column 402 to rotate, moving it away from the mounting bracket 401 along its shaft direction; the bottom end of the threaded column 402 pulls the central shaft 404 to move synchronously; the first sliding seat 405 moves synchronously with the central shaft 404; the inclined surface of the first sliding seat 405 and the inclined surface of the second sliding seat 406... When the first sliding seat 405 moves, it pushes the second sliding seat 406 outward through the inclined plane. The second sliding seat 406 pushes the support plate 407 to move outward synchronously. The slider 409 on one side of the support plate 407 slides in the sliding frame 408, thereby restricting the movement direction of the support plate 407. The four support plates 407 move outward synchronously, increasing the support range of the inner support mechanism 4. Rotating the handwheel 403 in the opposite direction can cause the support plate 407 to retract inward, reducing the support range of the inner support mechanism 4.

[0080] Please see Figures 7-8 The quenching mechanism 5 also includes a mounting plate 501, which is located on the inner wall of the top of the processing chamber 1; two slide rails 502, which are symmetrically arranged on the top of the mounting plate 501; a reciprocating screw 503, which is located between the two slide rails 502, and both ends of the reciprocating screw 503 are rotatably connected to the top block of the mounting plate 501; and a first motor 504, which is located on one side of the top block of the mounting plate 501, and the output end of the first motor 504 is connected to one end of the reciprocating screw 503.

[0081] The quenching mechanism 5 also includes a movable seat 505, which is located above the mounting plate 501 and is slidably connected to the slide rail 502, and a movable plate 506, which is located on top of the movable seat 505.

[0082] The quenching mechanism 5 also includes a drive wheel 507, which is rotatably connected to the outer wall of one side of the moving plate 506 at a corresponding position; driven wheels 508, which are rotatably connected to the outer wall of one side of the moving plate 506 at corresponding positions; a chain 509 is connected between the two driven wheels 508 and the drive wheel 507; and a second motor 510, which is located at the outer wall of the other side of the moving plate 506 at a corresponding position, and the output end of the second motor 510 is connected to the outer wall of one side of the drive wheel 507.

[0083] The quenching mechanism 5 also includes a rotating ring 511, which is located on one side of the moving plate 506. Two nozzles 513 are respectively connected to the corresponding positions on the outer wall of one side of the rotating ring 511. There are also limit wheels 512, and multiple limit wheels 512 are rotatably connected to the corresponding positions on the outer wall of one side of the moving plate 506.

[0084] Specifically: The second motor 510 drives the drive wheel 507 to rotate via its output end. The drive wheel 507 drives two driven wheels 508 to rotate via a chain 509. The links of the chain 509 simultaneously mesh with the teeth on the outer wall of the rotating ring 511, causing the chain 509 to drive the rotating ring 511 to rotate. The top plate of the driven wheel 508 and the limiting wheel 512 together restrict the position of the rotating ring, causing the rotating ring 511 to rotate around the axis of the moving plate 506. The profile is positioned on the axis of the moving plate 506 by the positioning mechanism 3 and the inner support mechanism 4, and the rotating ring 511 rotates around the axis of the profile. Two nozzles 513 rotate synchronously with the rotating ring 511, causing the two nozzles 513 to rotate around the profile axis, making the cooling water sprayed by the nozzles 513 evenly distributed on the profile surface and reducing cooling dead zones. The first motor 504 drives the reciprocating screw 503 to rotate through the output end. The external thread on the outer wall of the reciprocating screw 503 engages with the internal thread on the inner wall of the moving seat 505, allowing the moving seat 505 to make periodic reciprocating motion along the slide rail 502. The moving seat 505 drives the moving plate 506 to move synchronously, making the nozzles 513 reciprocate along the profile axis, making the overall quenching of the profile more uniform.

[0085] It should be noted that the selection of the first motor 504 and the second motor 510 and the control unit in the above description are selected as needed. This part is well-known technology in the field and will not be described in detail here.

[0086] It should be further explained that the reciprocating screw 503 described above is a closed helical track formed by two threaded grooves with the same pitch and opposite directions connected by a transition curve. The motion conversion is achieved by using the thrust of the helical side on the moving seat 505. This part is well known in the field and will not be described in detail here.

[0087] Working principle: During use, the operator uses tools to insert the high-temperature heated profile into the processing chamber 1 through the door 2. The operator starts the electric push rod 310, and the positioning mechanism 3 positions the profile at the axis of the positioning ring 302 from four directions. After positioning, the operator continues to insert the profile. The inner support mechanism 4 enters the circular inner hole of the profile from one end. After the profile is fully inserted, the operator turns the handwheel 403, and the inner support mechanism 4 supports and positions the inner wall of the profile. After the profile is fully positioned, the operator starts the first motor 504 and the second motor 510, so that the quenching mechanism 5 rotates around the profile axis and reciprocates along the profile axis to perform water quenching on the profile. After quenching, the operator turns the handwheel 403 in the opposite direction to reset the inner support mechanism 4 and pull out the quenched profile. The above operation is repeated to process the next profile.
