Description

Technical Field

[0001] This utility model belongs to the field of aluminum aging furnace technology, specifically relating to an aging treatment device for aluminum profiles. Background Technology

[0002] After extrusion molding, aluminum profiles typically undergo aging treatment to improve their mechanical properties and stability. A common method involves placing the aluminum material in an aging furnace and holding it at a set temperature for a period of time to further strengthen its internal structure. Currently, commonly used aluminum profile aging treatment equipment mainly includes a furnace body, a conveying mechanism, and a sealing door mechanism, and the treatment is completed by pushing the aluminum material into the furnace. However, existing equipment still has the following shortcomings in use.

[0003] First, most existing sealed doors use direct push-pull or electric lifting methods for opening and closing. Since sealed doors are usually heavy, they require a large driving force to open, which not only increases the motor load but also leads to high energy consumption. In particular, frequent opening and closing can easily cause wear and tear on the mechanism, affecting the service life of the equipment.

[0004] Secondly, after the sealing gate is closed, gaps often exist between the gate body and the slide rail due to factors such as the fit gap between the structures or friction and wear, which affects the sealing effect, easily causes heat loss, increased energy consumption, and even affects the heat treatment quality of the aluminum profile.

[0005] In addition, to ensure that the sealing gate is stably fixed in the closed state, simple limit devices or gate latches are often used. However, these structures lack reliable automatic control or energy buffering mechanisms during the force release and reset process, and may cause jamming or incomplete reset during use, which can easily affect the continuity of operation. Utility Model Content

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide an aluminum profile aging treatment device that can achieve a reasonable structure, low energy consumption for opening and closing, good sealing effect and automatic reset function, so as to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an aluminum profile aging treatment device, comprising a base, wherein rollers are uniformly and rotatably mounted on the upper surface of the base for conveying materials, an aging furnace body is provided on the rear side of the top of the base, the interior of the aging furnace body is hollow and open at the front, and sliding grooves are vertically opened on the inner walls of both sides of the aging furnace body near the open end, and a sealing gate is slidably installed between the two sliding grooves;

[0008] A compression bolt is evenly slidably installed on the front side of the chute. The compression bolt extends beyond the front surface of the base. The rear end of the compression bolt is pressed against the closed sealing gate. A connecting plate is provided at the front end of multiple compression bolts. Two of the connecting plates are placed vertically on both sides of the open end of the aging furnace body.

[0009] Furthermore, the aging furnace body is symmetrically provided with lower support platforms on both sides in front. Four columns are vertically fixed on the upper surface of the lower support platforms. A top plate is provided on the top of the four columns. Counterweights are slidably installed on the surface of the four columns. A fixed pulley is rotatably installed on the upper surface of the top plate. A steel wire rope is connected to the center of the top of the counterweight. The other ends of the two steel wire ropes pass around the fixed pulley and are respectively connected to the top two sides of the sealing gate.

[0010] Furthermore, one of the fixed pulleys is controlled by a motor, and a linkage belt drive mechanism is provided between the two fixed pulleys, so that the two fixed pulleys are kept in synchronous linkage through the linkage belt drive mechanism.

[0011] Furthermore, a spring is fitted on the surface of the compression bolt, the spring is placed on the outside of the aging furnace body, and the spring applies an outward thrust to the connecting plate.

[0012] Furthermore, mounting plates are symmetrically arranged on the front side of the aging furnace body, and a rotating shaft is horizontally mounted on the surface of each of the two mounting plates, with the rotating shaft located on the front center of the connecting plate.

[0013] Furthermore, an eccentric wheel is provided at one end of the rotating shaft and a gear is provided at the other end. The eccentric wheel is tangent to the outer surface of the connecting plate, and the rearward compression of the connecting plate is achieved by the rotation of the eccentric wheel.

[0014] Furthermore, both the lower support platform and the front side of the top plate are provided with fixing rings, and a sliding rod is vertically slidably installed between the two fixing rings on the same side. A toothed rod is provided at the bottom of the sliding rod, and the toothed rod meshes with a gear. A limiting plate is provided at the top of the sliding rod, and the limiting plate is placed above the top plate. A pressing rod is fixed above the rear side of the sliding rod, and the pressing rod is placed above the counterweight. When the sealing gate is closed, the counterweight moves up to the highest point and applies an upward pressing force to the toothed rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By installing multiple evenly arranged rollers on the base and driving them with a drive motor, the material plate loaded with aluminum profiles can be smoothly pushed into the aging furnace, thereby realizing the automation of aluminum profile feeding. This solves the problems of low efficiency and high labor intensity of traditional manual pushing, and improves production efficiency and automation.

[0017] By setting grooves on both sides of the open end of the aging furnace body and sliding the sealing gate in the grooves, a stable guide rail structure is constructed, which allows the sealing gate to run along a fixed path during opening and closing. This avoids the problem of jamming and displacement that is common in traditional door structures during frequent opening and closing, and improves the reliability and structural stability of the sealing gate operation.

[0018] By setting up a counterweight transmission structure consisting of columns, top plate, counterweight blocks, wire ropes and fixed pulleys on both sides of the aging furnace body, and using a linkage belt transmission mechanism to ensure that the fixed pulleys work synchronously, the driving force required for the sealing gate to open is significantly reduced. The counterweight blocks provide a reverse force that effectively offsets the weight of the gate body, solving the problems of high motor power demand and high energy consumption in traditional devices, and improving the energy efficiency and service life of the structure.

[0019] By setting up a compression bolt, connecting plate, and spring mechanism in front of the sealing gate, and coordinating the pushing action of the slide bar during the rise of the counterweight, the rack, gear, and eccentric wheel are driven to perform linkage compression, so that multiple compression bolts form a stable pressure on the rear surface of the sealing gate. This solves the problem of sealing gaps caused by long-term wear between the traditional gate and the furnace body slide groove, improves the sealing effect, and effectively prevents heat leakage and uneven heat treatment.

[0020] By setting a limit plate to constrain the maximum stroke of the slide bar, the stability of the slide bar's movement is ensured and it is prevented from coming off. At the same time, the mechanical conversion of the extrusion action is achieved through the tangential pressing structure between the eccentric wheel and the connecting plate. The overall structure realizes automatic positioning and pressing and fixing of the sealing door, which solves the problems of unstable position and incomplete reset of the sealing door after closing in the prior art, and improves the safety and airtightness of the heat treatment process.

[0027] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0028] refer to Figures 1-5 As shown, an aging treatment device for aluminum profiles includes a base 1. Rollers 11 are uniformly rotatably mounted on the upper surface of the base 1 for conveying materials. The rollers 11 are connected to the base 1 through bearing seats to achieve stable rotation and are driven by a transmission motor installed inside the base 1 to achieve automated conveying. An aging furnace body 2 is provided on the rear side of the top of the base 1. The interior of the aging furnace body 2 is hollow and the front is open to accommodate a material plate loaded with aluminum profiles. Slide grooves 21 are vertically opened on the inner walls of both sides of the aging furnace body 2 near the open end. A sealing gate 3 is slidably installed between the two slide grooves 21. The sealing gate 3 is an integral metal plate structure, and its two side edges fit tightly with the slide grooves 21 to form a sealed track to prevent heat leakage from the furnace.

[0029] A compression bolt 9 is evenly slidably installed on the front side of the slide 21. The compression bolt 9 extends beyond the front surface of the base 1, and the rear end of the compression bolt 9 presses against the closed sealing gate 3. A connecting plate 91 is provided at the front end of multiple compression bolts 9. The connecting plate 91 is a flat metal component used to drive multiple compression bolts 9 to move in a coordinated manner. The two connecting plates 91 are vertically placed on both sides of the opening of the aging furnace body 2, corresponding to and cooperating with the outer surface of the sealing gate 3. This ensures that when the gate is closed, multiple compression bolts 9 driven by the connecting plate 91 press the sealing gate 3 backward together, improving the tightness of the fit between the gate and the rear wall of the slide 21, thereby solving the problem of heat leakage caused by the gaps generated by friction and wear.

[0030] refer to Figures 1-3As shown, symmetrical lower support platforms 22 are arranged on both sides of the front of the aging furnace body 2. The lower support platforms 22 are welded and fixed structures that support the guide rail assembly. Four columns 23 are vertically fixed on the upper surface of the lower support platforms 22. The four columns 23 are hollow tubular structures used to guide the up and down sliding of the counterweight blocks 6. A top plate 24 is provided on the top of the four columns 23. The top plate 24 is an integral connecting component that stabilizes the fixed pulley 26 and supports the overall counterweight mechanism. The counterweight blocks 6 are slidably installed on the surface of the four columns 23. The counterweight blocks 6 are made of high-density gold. The counterweight 6 is a block whose vertical sliding path is guided and controlled by the column 23; a fixed pulley 26 is rotatably installed on the upper surface of the top plate 24, and the axis of the fixed pulley 26 is fixedly connected to the top plate 24; a steel wire rope 5 is connected to the top center of the counterweight 6, and two steel wire ropes 5 are respectively laid along the upward direction of the column 23, and the other end passes around the fixed pulley 26 and is connected to the top two sides of the sealing gate 3, so that the weight of the counterweight 6 is used to offset part of the self-weight of the sealing gate 3, thereby reducing the driving force when the motor opens the sealing gate 3, improving structural stability and reducing energy consumption.

[0031] refer to Figures 1-3 As shown, one of the fixed pulleys 26 is controlled by a motor, which is located on the top of the top plate 24 and drives the pulley to rotate through the motor output shaft; a linkage belt transmission mechanism 4 is set between the two fixed pulleys 26, which includes a synchronous pulley and a synchronous belt assembly to ensure that the two fixed pulleys 26 rotate synchronously under the drive of the motor; the two fixed pulleys 26 are kept synchronously linked by the linkage belt transmission mechanism 4 to avoid uneven force on both sides of the wire rope 5 causing the sealing gate 3 to deviate during the opening or closing process, thereby improving the reliability and stability of the overall transmission structure.

[0032] refer to Figure 3 and Figure 5 As shown, a spring 92 is fitted on the surface of the compression bolt 9. The spring 92 is placed on the outside of the aging furnace body 2. The spring 92 is a helical compression spring. One end of the spring is fixed between the compression bolt 9 and the connecting plate 91, and the other end abuts against the furnace body fixing plate, applying an outward pushing force to the connecting plate 91. This structure ensures that the rear end of the compression bolt 9 will not enter the slide groove 21 in the non-compression state, thereby avoiding mechanical obstruction to the normal descent of the sealing gate 3 and effectively cooperating with the gate closing process.

[0033] refer to Figures 3-5 As shown, mounting plates 27 are symmetrically arranged on the front side of the aging furnace body 2. The mounting plates 27 are used to install the rotary drive structure. The two mounting plates 27 are horizontally mounted with rotating shafts 8. The rotating shafts 8 axially pass through the mounting plates 27 and are supported by bearings to achieve smooth rotation. The rotating shafts 8 are located on the center front side of the connecting plate 91, which facilitates the eccentric pressing action with the connecting plate 91.

[0034] refer to Figures 3-5As shown, an eccentric wheel 81 is provided at one end of the rotating shaft 8, and the outer circumference of the eccentric wheel 81 is tangent to the outer surface of the connecting plate 91. A gear 82 is provided at the other end of the rotating shaft 8, and the gear 82 is used to mesh with the rack 72 of the control device. The rotation of the eccentric wheel 81 realizes the backward compression of the connecting plate 91, thereby driving multiple compression bolts 9 to move backward as a whole, so that the rear surface of the sealing gate 3 and the inner wall of the rear side of the slide 21 can make close contact, improve the sealing performance of the aging furnace, and prevent heat leakage inside the furnace.

[0035] refer to Figure 1 , Figure 3 and Figure 4 As shown, both the lower support platform 22 and the front of the top plate 24 are equipped with fixing rings 25, which are used to guide the installation of the sliding structure. A slide rod 7 is vertically slidably installed between the two fixing rings 25 on the same side. The slide rod 7 is a long strip-shaped metal guide, and its lower end is equipped with a rack 72. The rack 72 is a rack and tooth structure that precisely meshes with the gear 82, which can drive the gear 82 to rotate during the up and down movement of the slide rod 7. A limit plate 71 is provided at the top of the slide rod 7. The limit plate 71 is fixed to the top of the slide rod 7 by screwing and placed on the top plate 24. Above, a limit is placed on the maximum upward travel of the slide bar 7. A pressing rod 73 is fixed above the rear side of the slide bar 7. The pressing rod 73 is a vertical rod and is set above the counterweight block 6. When the sealing gate 3 is closed, as the sealing gate 3 descends to the lowest position, the counterweight block 6 moves up to the top. The top of the counterweight block 6 applies an upward pressing force to the pressing rod 73, thereby driving the slide bar 7 to move upward as a whole and driving the gear 82 to rotate. Finally, the eccentric wheel 81 is synchronously pressed against the connecting plate 91, so that the sealing structure is in a closed state.

[0036] The working principle of this utility model is as follows: aluminum materials are stacked on a material plate, and then the material plate is pushed into the aging furnace body 2 by the roller 11. When the sealing gate 3 is opened and closed, the rotation of the fixed pulley 26 is controlled by the motor, which in turn drives the steel wire rope 5 to move. The linkage belt transmission mechanism 4 can make the two fixed pulleys 26 move synchronously, which in turn makes the steel wire ropes 5 on both sides move synchronously. The weight of the two counterweights 6 is less than that of the sealing gate 3, so as to reduce the power required to open the sealing gate 3, thereby reducing the energy consumption of opening the sealing gate 3. It is suitable for opening relatively heavy sealing gates 3.

[0037] Because the spring 92 applies an outward pushing force to the connecting plate 91, the unforced compression bolt 9 is positioned at the front of its stroke. At this time, the rear end face of the compression bolt 9 does not enter the inner side of the slide groove 21 to prevent it from obstructing the fall of the sealing gate 3. When the sealing gate 3 falls to the lowest position, the counterweight 6 moves up to the highest position, and then compresses the compression rod 73, causing the slide rod 7 to move upward as a whole. At this time, the meshing of the rack 72 and the gear 82 can drive the rotating shaft 8 to rotate, and then the eccentric wheel 81 can compress the connecting plate 91, causing multiple compression bolts 9 to slide backward to compress both sides of the sealing gate 3, so that the rear surface of the sealing gate 3 is tightly attached to the inner side of the rear side of the slide groove 21, thereby improving the sealing performance and preventing the problem of insufficient sealing performance caused by increased gaps between the sealing gate 3 and the slide groove 21 due to long-term use. The limiting plate 71 at the top of the slide rod 7 is used to prevent the slide rod 7 from falling.

[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
