Description

Technical Field

[0001] This invention relates to the field of heat treatment equipment technology, and more specifically to an adaptive profile heat treatment support mechanism for intelligent manufacturing production lines. Background Technology

[0002] In intelligent manufacturing production lines, heat treatment of profiles (such as aluminum alloy profiles and steel profiles) is a key process for improving the mechanical properties and service life of materials. Typically, profiles need to be fed into a heating furnace for heating, heat preservation, and subsequent cooling or painting. During this process, a support structure is used to support the profiles and ensure they are heated stably and evenly within the furnace.

[0003] Currently, existing profile heat treatment support mechanisms have a limited number of profiles that can be processed at one time. They can only support a single layer or a very small number of profiles, making it difficult to make full use of the internal space of the heating furnace. This results in a limited number of profiles that can be processed at one time, which cannot meet the high-efficiency and batch production requirements of intelligent manufacturing production lines.

[0004] Furthermore, profiles of different specifications vary significantly in length, width, and cross-sectional shape (e.g., square tubes, round tubes). Existing support structures typically have fixed, non-adjustable support spans, making it difficult to provide stable support for profiles with different cross-sectional shapes. In addition, the load-bearing plane layout is often a simple row-column alignment, leading to uneven hot airflow within the heating furnace and affecting the consistency of heat treatment effects for multiple profiles simultaneously. Moreover, existing support structures generally use large-area or surface contact methods to support the profiles, resulting in slow heating at the contact points due to obstruction, creating significant heat treatment dead zones and affecting product quality consistency. More importantly, profiles themselves undergo cross-sectional thermal expansion under high-temperature environments, while the span of traditional support points remains constant, failing to adaptively compensate for this expansion deformation, potentially leading to compressive deformation of the profiles. Therefore, we propose an adaptive profile heat treatment support mechanism for intelligent manufacturing production lines. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an adaptive profile heat treatment support mechanism for intelligent manufacturing production lines. It overcomes the deficiencies of existing technologies, has a reasonable design and compact structure, and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adaptive profile heat treatment support mechanism for intelligent manufacturing production lines, comprising:

[0007] A heating furnace having an opening at the bottom of its body, the opening being covered by a sealing plate;

[0008] The track is located below the furnace body of the heating furnace;

[0009] The trolley is slidably mounted on the track;

[0010] A scissor lift is installed on top of the trolley;

[0011] A heat insulation board is installed on the top of the scissor lift, and the outline dimensions of the heat insulation board are adapted to the opening;

[0012] A support assembly is installed on the top of the heat insulation board and can follow the heat insulation board vertically into or out of the opening;

[0013] The support assembly includes a base plate, and the top of the base plate is provided with multiple support units. Each support unit includes a pair of parallel slide rails. A pair of adjusting plates slide together on the two slide rails. Each adjusting plate has multiple grooves equidistantly spaced along its length. A pair of bearing plates are slidably connected in each groove. A lead screw is rotatably connected in each adjusting plate. The lead screw is threadedly engaged with all the bearing plates on the corresponding adjusting plate, and the threads of the bearing plates in the same groove are opposite, so that when the lead screw rotates, the two bearing plates in the same groove move towards or in opposite directions.

[0014] Preferably, the support assembly further includes several lifting and adjusting units and multiple support plates;

[0015] The lifting adjustment unit includes a sleeve disposed on the top of the adjustment plate. Vertical grooves are symmetrically opened on the outer wall of the sleeve. A lifting column is vertically slidably connected inside the sleeve. Limiting columns are symmetrically arranged on the outer wall of the lifting column. Each limiting column passes through the corresponding vertical groove.

[0016] A limiting frame is rotatably connected to the sleeve, and the limiting frame is provided with a hook portion that cooperates with the limiting post; when the limiting post moves upward, by rotating the limiting frame, the hook portion can be made to fit against the lower part of the limiting post, thereby limiting the position of the limiting post.

[0017] Each of the support plates is mounted on top of the two lifting columns in the same row, and the slide rails in the upper lifting adjustment unit are arranged on the top surface of the support plate.

[0018] Preferably, the outer wall of the sleeve is symmetrically provided with sliding grooves, and a limit block is slidably arranged in each sliding groove;

[0019] The end of the limiting block inserted into the sliding groove is connected to the sleeve by a spring, and the top of the end of the limiting block extending out of the sliding groove has a slope.

[0020] When the limiting frame rotates downward, the inclined surface is pressed, causing the limiting block to slide into the sliding groove.

[0021] Preferably, the support plate has a U-shaped structure, and its length direction is consistent with the placement direction of the profile, so that the top of the support plate forms two support points for the profile.

[0022] Preferably, the bearing plate includes a sliding plate and two support blocks;

[0023] The sliding plate has a pair of adjustment slots, and the bottom of the support block has an insert block that is inserted into the corresponding adjustment slot.

[0024] Multiple thermally expanding metal sheets are provided between the insert block and the inner wall of the adjusting groove.

[0025] Preferably, the thermally expanded metal sheet has an arc-shaped structure and is positioned towards the side of the profile supported on the support plate.

[0026] Preferably, the top of the adjusting plate has several pairs of supporting plates arranged in a trapezoidal shape.

[0027] Preferably, the top of the top support plate is provided with a conical positioning post, and the bottom of the sealing plate is provided with a positioning groove that matches the conical positioning post. When the support assembly moves upward, the conical positioning post is inserted into the positioning groove and drives the sealing plate to move upward together.

[0028] This invention provides an adaptive profile heat treatment support mechanism for intelligent manufacturing production lines. It offers the following advantages:

[0029] 1. The support assembly adopts a multi-layer support unit, which can simultaneously support multiple profiles entering the heating furnace, significantly improving the quantity of heat treatment in a single process and the overall efficiency of the production line.

[0030] 2. In each support unit, two adjusting plates can move independently and lock along the slide rail, accommodating different profile types. Simultaneously, by rotating a lead screw, two bearing plates with opposite rotation directions within the same slide groove can move towards or away from each other, precisely adjusting the support span to meet the stable support requirements of profiles with different cross-sectional shapes, such as square and round tubes. Several pairs of bearing plates at the top of each adjusting plate in each support unit are arranged in a trapezoidal pattern, ensuring more uniform temperature flow throughout the heating furnace and improving the consistency of heat treatment results when multiple profiles are heat-treated simultaneously.

[0031] 3. The lifting adjustment unit can manually lock the lifting column in a high or low position, thereby changing the vertical spacing between each layer of support units, effectively avoiding contact between multiple layers of profiles or heat radiation blockage; the high position also facilitates rapid cooling of the profiles after heat treatment or drying after painting.

[0032] 4. The support plate adopts a U-shaped structure, with each U-shaped plate providing two support points, resulting in high support stability and significantly reducing heat treatment dead zones caused by large-area contact. The support plate contains arc-shaped thermally expanding metal sheets that expand under high temperatures in the furnace, pushing the support blocks outwards. This adaptively compensates for the minor deformation of the profile cross-section caused by thermal expansion and dynamically changes the contact position of the support points, avoiding uneven heat treatment problems caused by fixed contact points.

[0033] 5. The top support plate is equipped with a conical positioning post that cooperates with the conical positioning groove at the bottom of the sealing plate. When the lifting mechanism rises, it automatically opens the sealing plate and achieves centering. When it descends, the sealing plate automatically resets and closes the opening by gravity. No separate drive mechanism is required, which effectively reduces heat loss from the furnace body and simplifies the equipment structure. Attached Figure Description

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0048] like Figures 1 to 12 As shown, this embodiment provides an adaptive profile heat treatment support mechanism for a smart manufacturing production line. This mechanism provides stable, adjustable, and well-insulated support for profiles (such as aluminum alloy profiles, steel profiles, etc.) as they enter the heating furnace 1 for heat treatment.

[0049] The profile support mechanism includes: heating furnace 1, track 2, trolley 3, scissor lift 4, heat insulation plate 5, and support components.

[0050] The heating furnace 1 has an opening 11 at the center of the bottom of the furnace body for feeding and discharging materials. In the non-operating state or when the furnace body requires sealing, a detachable sealing plate 12 is placed over the opening 11. The sealing plate 12 is usually made of the same heat-resistant material as the furnace body to ensure the thermal seal of the bottom of the furnace body.

[0051] Track 2 is fixedly laid on the ground directly below the furnace body of heating furnace 1, and its extension direction is consistent with the conveyor direction of the production line or set as needed. Trolley 3 is slidably mounted on track 2 and can be driven by a drive mechanism such as a motor, cylinder or chain (not specifically shown in the figure) to move back and forth along track 2.

[0052] The scissor lift 4 is fixedly installed in the center of the top platform of the trolley 3. The scissor lift 4 is existing technology; it is driven by a hydraulic cylinder or electric screw and provides smooth, long-stroke vertical lifting motion. A heat insulation plate 5 is fixedly installed on top of the scissor lift 4. The planar profile of the heat insulation plate 5 is adapted to the opening 11 at the bottom of the heating furnace 1, allowing it to fit tightly into the opening 11, serving a sealing and heat insulation function. The heat insulation plate 5 is made of the same heat-resistant material as the furnace body to prevent the downward conduction of high temperatures inside the furnace, reducing heat loss.

[0053] The support assembly is installed on top of the heat insulation plate 5 and can move vertically together with the heat insulation plate 5. When the scissor lift 4 is lifted upward, the support assembly passes through the opening 11 and enters the interior of the heating furnace 1; when the scissor lift 4 is retracted, the support assembly exits from the opening 11 and descends to the outside of the furnace body.

[0054] To increase the number of profiles that can be heat-treated at one time, the support assembly includes a base plate 61 and a multi-layer support unit disposed on top of the base plate 61. This embodiment shows two layers of support units, but depending on the length of the profiles and the height of the heating furnace 1, it can be configured with three, four, or more layers.

[0055] Each support unit includes a pair of parallel slide rails 621. These slide rails 621 are fixed to the top of the base plate 61 or the lower support plate 64. Two adjusting plates 622 are slidably connected to the two slide rails 621. Each adjusting plate 622 has its bottom ends slidably engaged with the corresponding slide rail 621 via sliders, allowing the two adjusting plates 622 to move independently along the length of the slide rails 621 to adjust the distance between them, thus accommodating different profile specifications. Bolts are threaded onto the sides of the adjusting plates 622, with the ends of the bolts abutting against the sidewalls of the slide rails 621 to lock the position of the adjusting plates 622 and the slide rails 621.

[0056] Each adjusting plate 622 is a long strip-shaped plate structure, with multiple rectangular grooves 623 evenly spaced along the length of each adjusting plate 622. A pair of bearing plates 624 are slidably connected in each groove 623. The bottoms of the two bearing plates 624 in the same groove 623 have internal threads, and the directions of the internal threads are opposite.

[0057] Inside each adjusting plate 622, a lead screw 625 is rotatably connected along its length. The lead screw 625 is rotatably mounted inside the adjusting plate 622, with its end extending out of the adjusting plate 622 and connected to a handwheel. The lead screw 625 engages with the internal thread structure at the bottom of all the bearing plates 624 on the same adjusting plate 622. The internal threads of two bearing plates 624 located in the same groove 623 have opposite directions. Therefore, when the lead screw 625 rotates in a certain direction, the two bearing plates 624 in the same groove 623 will move towards or in opposite directions. By rotating the lead screw 625, the span between the two support beams at each support point can be precisely adjusted to accommodate the stable support requirements of profiles with different cross-sectional shapes (such as square tubes and round tubes).

[0058] To facilitate rapid heat dissipation of the profiles after high-temperature heat treatment or rapid drying after painting, the support assembly also includes several lifting and adjusting units and multiple support plates 64.

[0059] The lifting adjustment unit includes a sleeve 631 fixedly mounted on the top surface of the adjustment plate 622. Two vertical grooves 632 extending in the vertical direction are symmetrically formed on the outer wall of the sleeve 631. A lifting column 633 is vertically slidably connected inside the sleeve 631, and the top of the lifting column 633 is used to support the upper structure. Two limiting posts 634 are symmetrically arranged on the outer wall of the lifting column 633, each limiting post 634 passing through and extending out of a corresponding vertical groove 632.

[0060] A limiting bracket 635 is rotatably connected to the outside of the sleeve 631. The limiting bracket 635 has a hook portion 636 that engages with the limiting post 634. When the profile placed on the support assembly needs cooling or drying after painting, the operator lifts the upper support plate 64 upwards. At this time, the lifting post 633 drives the limiting post 634 upwards along the vertical groove 632 to a high position. Subsequently, the limiting bracket 635 is rotated, causing the hook portion 636 to rotate directly below and engage with the limiting post 634, thereby locking the limiting post 634 in the high position and fixing the extension height of the lifting post 633. This makes the entire support assembly relatively higher, facilitating subsequent cooling and drying.

[0061] Each support plate 64 is mounted on top of two lifting columns 633 in the same row. The slide rail 621 in the upper support unit is fixedly arranged on the top surface of the support plate 64. With this structure, the operator can adjust the lifting column 633 of each lifting unit to a low or high position according to the height of the profile or the interference between different layers of profiles, while ensuring the number of profiles processed each time. This changes the vertical spacing between the support units and achieves adaptive adjustment in the support height direction, avoiding contact or heat radiation blockage between multiple layers of profiles in the heating furnace 1.

[0062] To facilitate quick locking and unlocking of the lifting column 633 and prevent accidental disengagement of the limit bracket 635, two symmetrical sliding grooves 637 are provided on the outer wall of the sleeve 631. The positions of the sliding grooves 637 are offset from the vertical groove 632. A limit block 639 is slidably installed in each sliding groove 637. One end of the limit block 639 inserted into the sliding groove 637 is connected to the inner wall of the sleeve 631 through a compression spring 638. The spring 638 always applies an outward pushing force to the limit block 639. The top of the end of the limit block 639 extending out of the sliding groove 637 is designed as a slope.

[0063] When the limiting bracket 635 rotates downwards, its bottom wall first contacts the inclined surface at the top of the limiting block 639. Guided by the inclined surface, the limiting block 639 is pressed into the sliding groove 637, simultaneously compressing the spring 638. As the limiting bracket 635 continues to rotate and passes the limiting block 639, the spring 638 pushes the limiting block 639 out again. At this point, the non-inclined end of the limiting block 639 is precisely positioned above the limiting bracket 635, preventing it from returning upwards, thus achieving self-locking. To unlock, simply press the limiting block 639 to retract it, allowing the limiting bracket 635 to rotate upwards.

[0064] To reduce heat treatment dead zones caused by the contact between the profile and the support plate 624 during profile support, the support plate 624 has an overall U-shaped structure, with its length aligned with the placement direction of the profile. When the U-shaped opening of the support plate 624 faces upward, two support points are formed at the top ends of each support plate 624. Therefore, for a single profile, two pairs of support plates 624 (a total of four U-shaped support plates 624) are used for support on the two adjusting plates 622, with each U-shaped support plate 624 providing two support points, for a total of eight support points. This greatly improves the stability of the support and reduces heat treatment dead zones caused by large-area contact.

[0065] Furthermore, the support plate 624 includes a sliding plate 6241 and two support blocks 6242. The bottom of the sliding plate 6241 is threaded into a lead screw 625. A pair of adjustment grooves 6243 are formed on the top surface of the sliding plate 6241. Each support block 6242 has an insert 6244 at its bottom, which is inserted into the corresponding adjustment groove 6243 and can slide along the adjustment groove 6243 in a direction away from or towards the profile it supports. A plurality of arc-shaped thermally expandable metal sheets 6245 are provided between the inner sidewall of the insert 6244 and the adjustment groove 6243 on the side closer to the profile. The thermally expandable metal sheets 6245 are made of an expansion alloy material (such as manganese copper alloy), and both ends of the thermally expandable metal sheets 6245 are respectively connected to the insert 6244 and the adjustment groove 6243.

[0066] When the temperature inside the heating furnace 1 rises, the thermally expanding metal sheet 6245 expands due to heat, its curvature decreases, and its length increases. This pushes the insert block 6244 and the support block 6242 away from the profile, increasing the span between the two support blocks 6242. This design not only adaptively compensates for the slight expansion deformation that may occur in the profile cross-section at high temperatures, but also changes the position of the support point on the profile during the outward deformation process. This avoids heat treatment dead zones caused by the fixed contact point between the support block 6242 and the profile, thus ensuring the heat treatment effect.

[0067] To further optimize space utilization and heat treatment effect, this embodiment specifies the arrangement of the support plates 624. Several pairs of support plates 624 on top of each adjusting plate 622 in each support unit are arranged in a trapezoidal shape. This trapezoidal layout makes the temperature flow more uniform throughout the furnace body of the heating furnace 1, effectively improving the heat treatment effect of the entire support assembly when supporting multiple profiles.

[0068] To reduce heat loss when the profile enters and exits the furnace cavity of heating furnace 1, a sealing plate 12 is installed at the opening 11. To solve the problem of automatic opening and closing of the sealing plate 12, each top support plate 64 is symmetrically provided with an upwardly protruding conical positioning post 65. Correspondingly, several conical positioning grooves matching the shape of the conical positioning post 65 are opened at the bottom of the sealing plate 12. When the scissor lift 4 drives the support assembly to move upward, the conical positioning post 65 first enters the conical positioning groove at the bottom of the sealing plate 12 and automatically centers itself by the guiding action of the conical surface. As the support assembly continues to rise, the conical positioning post 65 lifts the sealing plate 12 from the opening 11, causing both to move upward together. When the support assembly descends, the sealing plate 12 closes back onto the opening 11 under the action of gravity. This structure realizes the automatic opening and closing of the sealing plate 12 without the need for an additional drive mechanism, simplifying the equipment structure.
