[0022] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0023] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0024] Examples, such as Figure 1 , 2As shown in , 3, a continuous roller bottom quenching production system for aluminum alloy comprises a heating furnace 1 and a conveying line; a roller bottom conveying line arranged through the heating furnace 1, the roller bottom conveying line comprising a left roller bottom branch line and a right roller bottom branch line, the left roller bottom branch line and the right roller bottom branch line are arranged at intervals from left to right and extend forward and backward for conveying; in this embodiment, the aluminum alloy workpiece is supported and conveyed by the left and right rows of roller bottom branches for heating furnace 1; the heating furnace 1 is a quenching furnace, which can be better heated by the separate support on the left and right sides; specifically, the left roller bottom branch line comprises a row of left conveying support rollers 21 which are arranged on the left side furnace wall of the heating furnace 1 and are spaced apart from each other; the right roller bottom branch line comprises a left conveying support roller 21 which is arranged on the left side furnace wall of the heating furnace 1 and is spaced apart from each other; The branch line includes a row of right conveying support rollers 31 that are penetrated on the right furnace wall of the heating furnace 1 and spaced apart from each other. The left and right side walls of the heating furnace 1 can be installed with embedded bearings for the left and right conveying support rollers 21 and 31 to penetrate, support and rotate conveniently. The bearings can be high-temperature bearings and can be used at high temperatures. Furthermore, a left pre-limiting plate 211 is installed on the left conveying support roller 21, and a right pre-limiting plate 311 is installed on the right conveying support roller 31. The axes of the left and right conveying support rollers 21 and 31 are both in the left and right directions. The left pre-limiting plate 211 is used to limit the aluminum alloy workpiece on the left, and the right pre-limiting plate 211 is used to limit the aluminum alloy workpiece on the right. The pre-limiting plate 311 is used to limit the aluminum alloy workpiece on the right side. The pre-limiting means that, first of all, the number of the left pre-limiting plates 211 and the right pre-limiting plates 311 is the same, and the front and rear positions correspond one to one to the left and right, that is, the left and right conveying support rollers correspond one to one to the left and right, then the corresponding interval between the left pre-limiting plate 211 and the right pre-limiting plate 311 forms a limit for the aluminum alloy workpiece, but the interval between the left pre-limiting plate 211 and the right pre-limiting plate 311 is larger than the left and right dimensions of the aluminum alloy workpiece. For a regular rectangular aluminum alloy plate workpiece, the left and right sides of the aluminum alloy plate workpiece are respectively There is a gap between the left pre-limiting plate 211 and the right pre-limiting plate 311, that is, they can move left and right, but this pre-limiting is to facilitate the aluminum alloy workpiece to enter the furnace smoothly, so that the aluminum alloy workpiece can be between the left pre-limiting plate 211 and the right pre-limiting plate 311, and then there is a more effective limit. The left pre-limiting plate 211 can be mounted and fixed on the left conveying support roller 21, and can be fixed in an existing adjustable and detachable manner, or in a fixing manner that is not easy to adjust, such as welding. The installation and connection method of the right pre-limiting plate 311 on the right conveying support roller 31 can refer to the left side.The left conveying support roller 21 on the right side of the left pre-limiting plate 211 is used as the left end support section 212, and the right conveying support roller 31 on the left side of the right pre-limiting plate 311 is used as the right end support section 312. The left end support section 212 and the right end support section 312 are used to support the aluminum alloy workpiece on the left and right sides respectively and form a heating circulation zone 23 with a left and right interval. The setting is to support the aluminum alloy workpiece by two separate left end support sections 212 and right end support sections 312 on the left and right sides. The advantage of this is that a large space can be reserved at the bottom of the aluminum alloy workpiece for heating, and the heating will not be affected by the lower support roller blocking, that is, a large space can be reserved on the lower side of the aluminum alloy for heating, so that the uniformity of the upper and lower heating can be greatly improved. The left and right lengths of the left and right end support sections 212 and the right and left end support sections 312 can be set slightly smaller. For example, the left and right lengths of the left end support section 212 do not exceed one-fourth of the left and right lengths of the aluminum alloy workpiece. The heating circulation zone 23 has a large enough area on the lower side of the aluminum alloy workpiece. In addition, the density of the left conveying support roller 21 and the right conveying support roller 31 is relatively large, ensuring that there are at least two groups of left conveying support rollers 21 and right conveying support rollers 31 to support and convey an aluminum alloy workpiece when it is heated.

[0025] Preferably, the left end of the left conveying support roller 21 is located on the left outer side of the heating furnace 1 and is connected by a left chain 41, and the right end of the right conveying support roller 31 is located on the right outer side of the heating furnace 1 and is connected by a right chain 42, wherein the left end of the left conveying support roller 21 needs to be installed with a connecting sprocket, and the left chain 41 is wound around all the left sprockets. Of course, a left driving sprocket is also required, and the driving sprocket is wound inside the left chain 41, and the driving sprocket is connected to a driving motor, so that the rotation of the left conveying support roller 21 can be controlled by controlling the driving motor, thereby driving the aluminum alloy workpiece to travel and heat in the furnace. The transmission structure on the right side can be implemented in the same way as on the left side.

[0026] The heating furnace 1 is provided with a left support tube 51 extending from the bottom to the top, and the upper end of the left support tube 51 is connected with a left inner rotating support body 511 for supporting and rotating the left conveying support roller 21. The heating furnace 1 is also provided with a right support tube 52 extending from the bottom to the top, and the upper end of the right support tube 52 is connected with a right inner rotating support body 521 for supporting and rotating the right conveying support roller 31. It should be noted that the structures in the furnace are all made of high temperature resistant materials. The left support tube 51 and the right support tube 52 are fixed at the bottom of the furnace and are upright. Since the left conveying support roller 21 and the right conveying support roller 31 are only supported by one side of the furnace wall when they are set, the stability is relatively poor, easy to roll over, unstable, and there will be safety hazards. Therefore, through the secondary support of the support tube in the furnace, it can be more stable. At the same time, the left inner rotating support body 511 needs to be used in conjunction with the left conveying support roller 21 to better support the left conveying support roller 21 and operate smoothly. The same is true for the left side structure.

[0027] Furthermore, a plurality of gas nozzles 50 are installed on the left support tube 51 and the right support tube 52 and are arranged at intervals up and down. Of course, many gas nozzles are arranged at the top and bottom of the heating furnace 1 for heating. The heating furnace 1 of this embodiment is also suitable for gas ignition heating, and the left support tube 51 and the right support tube 52 are provided with gas nozzles 50, so that secondary heating can be performed in a specific area, and the gas pipeline can be arranged in the left support tube 51 and the right support tube 52, and extend from the outside of the furnace into the furnace. In addition, the left support tube 51 and the right support tube 52 can also be connected to a blow pipe, which can blow air in the high temperature area and evenly distribute the heat to other locations. There can be multiple gas nozzles and blow pipes, which is convenient for refined control.

[0028] Preferably, the left pre-limiting plate 211 and the right pre-limiting plate 311 are both annular plates, and the periphery of the left pre-limiting plate 211 is provided with a left limiting annular plate 61 which can move left and right, and the left limiting annular plate 61 is installed and connected with a left rotating limiting body 611 for abutting and limiting the left side of the aluminum alloy workpiece, that is, the left limiting annular plate 61 is sleeved on the periphery of the left pre-limiting plate 211, and the inner ring size of the left limiting annular plate 61 is larger than the outer ring size of the left pre-limiting plate 211, and the left limiting annular plate 61 is not used to support the workpiece, but only for the left side of the workpiece. The left limit ring plate 61 is required to be able to move left and right, and the workpiece moves very slowly, because it takes a long time to heat in the heating furnace, and it needs to move very slowly. Then, after the workpiece enters, the left limit ring plate 61 needs to move to the right, especially the left rotation limit body 611 needs to be against the left side of the workpiece for limiting. Similarly, the periphery of the right pre-limiting plate 311 is provided with a right limit ring plate 62 that can move left and right, and the right limit ring plate 62 is installed and connected with a right rotation limit body 621 for limiting the right side of the aluminum alloy workpiece. The spacing distance between the left rotation limit body 611 and the right rotation limit body 621 is obviously smaller than the spacing distance between the left pre-limiting plate 211 and the right pre-limiting plate 311, so that accurate limiting can be better performed. The left limit ring plate 61 and the right limit ring plate 62 can be connected to the corresponding existing left and right moving structures on the left and right sides.

[0029] Furthermore, the left limit ring plate 61 is also connected to a left elastic support connection assembly for elastically pressing and abutting the left side of the aluminum alloy workpiece on the left side. The left elastic support connection assembly can be a structure in which a damping rod is connected to an ordinary shaft rod. The other end of the shaft rod is fixedly connected to the left limit ring plate 61. The shaft rod can be set through the left side wall of the heating furnace, and the damping rod is on the outside. The other end of the damping rod can be connected to a cylinder or a linear motor that moves left and right for it to move left and right. In this way, the left limit ring plate 61 can move left and right, and the pressing and abutting of the left rotating limit body 611 can have a certain elastic force, reducing hard damage. The damping rod can also be replaced by a spring. Similarly, the right limit ring plate 62 is also connected to a right elastic support connection assembly for elastically pressing and abutting the right side of the aluminum alloy workpiece on the right side. The right elastic support connection assembly can refer to the left structure. Furthermore, the left inner rotating support body 511 and the right inner rotating support body 521 are both high-temperature bearings, and the left rotating limit body 611 and the right rotating limit body 621 are both high-temperature universal balls. This material selection is convenient for use in a heating furnace and does not affect the rotation of the roller and the smooth transportation of the workpiece.

[0030] Preferably, the left rotation limiter 611 has more than 4 and forms at least one annular array on the left limiter annular plate 61, and the right rotation limiter 621 has more than 4 and forms at least one annular array on the right limiter annular plate 62. Here, the left rotation limiter 611 and the right rotation limiter 621 are arranged in a full circle. This structure is suitable for the left limiter annular plate 61 and the right limiter annular plate 62 to be able to rotate themselves. Taking the left limiter annular plate 61 on the left side as an example, in this structure, the aforementioned shaft is replaced by a sleeve t1 that can surround the left conveying support roller 21, and the left conveying support roller 21 needs to be installed with a connecting bearing on the outside, and the sleeve t1 is sleeved on the bearing, and the right end of the sleeve is fixed on the left limit ring plate 61. The left side of the left limit ring plate 61 can be integrally connected with a connecting pipe t2 with the same aperture as the aperture of its inner ring. The sleeve t1 and the left end of the connecting pipe t2 are connected, and the outer periphery of the sleeve t1 can be provided with an annular groove t10 for connecting with the damping structure. For example, a roller or a universal wheel is installed and connected at the right end of the damping rod, and the roller or the universal wheel is placed in the annular groove t10, so that the left and right movement and the rotation of the left limit ring plate 61 itself will not be affected. The right limit ring plate 62 can be designed with reference to the left structure.

[0031] Preferably, the left support tube 51 and the right support tube 52 are both provided with a temperature detector 500, and each area before and after the temperature detector can realize temperature detection. The detection purpose is to understand the heating stability of each area in the furnace so as to control the temperature. For example, the area with low temperature can be further heated by the nozzle of the support tube, and the area with high temperature can be blown to balance the heat. In addition, the left elastic support connection assembly and the right elastic support connection assembly are both provided with a pressure sensor 7, which is mainly used to detect the extrusion force on the workpiece, and try to keep the balance between the left and right to avoid the quality of the workpiece caused by the uneven extrusion, and notify the sensor to obtain data to adjust the left and right movement position to change the pressure.

[0032] The above system design can make the heating process more optimized. 1. Problem definition,Goal: Make the temperature distribution of aluminum alloy more uniform during quenching by optimizing heating parameters. Objective function: Select a fitness function to quantify temperature uniformity, for example: Temperature standard deviation: Hope to minimize the standard deviation of temperature. Maximum and minimum temperature difference: Hope to minimize the difference between the maximum and minimum temperatures in the furnace.

[0033] 2. Parameter selection, determine the heating parameters that need to be optimized, including: Gas heating temperature: heating temperature setting for different areas. Heating time: heating duration at different stages. Roller bottom speed: the speed at which the aluminum alloy moves in the furnace. Gas flow rate: affects combustion efficiency and heat distribution.

[0034] 3. Data collection and modeling,Data collection: Use temperature sensors to monitor the temperature of aluminum alloy at multiple locations in the furnace under different heating conditions.,Modeling: Use the heat conduction model to establish a temperature distribution model to simulate the temperature changes under different parameters.

[0035] 4. Genetic algorithm implementation steps, 4.1 Initialize the population, randomly generate the initial population, each individual represents a set of heating parameter combinations [such as temperature, time, speed, etc.]. 4.2 Fitness evaluation, use the simulation model to evaluate each individual and calculate its fitness. The fitness function can be defined as: Fitness = 1 + σ (T) 1. Among them, σ (T) is the standard deviation of the temperature distribution, and the smaller the standard deviation, the higher the fitness.

[0036] 4.3 Selection operation, use selection strategies such as roulette selection, tournament selection, etc. to select individuals with high fitness for mating. Roulette selection: select individuals based on fitness ratio. Tournament selection: randomly select a group of individuals and select the individual with the highest fitness.

[0037] 4.4 Crossover operation: For the selected individuals, a crossover operation is performed to generate new individuals. Single-point crossover or multi-point crossover can be used. The specific operation is as follows: randomly select one or more crossover points and exchange the genes (parameter values) of the parent individuals at the crossover points.

[0038] 4.5 Mutation operation, in order to maintain the diversity of the population, mutation operation is performed. The specific method can be: randomly select certain parameters in individuals and make small random adjustments to them according to a certain probability (such as increasing or decreasing a certain value).

[0039] 4.6 Update the population and generate a new generation of population through selection, crossover and mutation operations. Repeat the fitness evaluation and selection process until the termination condition is met (such as reaching the maximum number of generations or fitness convergence).

[0040] 5. Result Analysis and Verification,5.1 Optimal Parameter Extraction,After the algorithm ends, the individual with the highest fitness is selected as the,optimal heating parameter combination.,5.2 Experimental Verification,According to the optimized parameter settings, an actual,

[0041] The above optimization method is very suitable for the system of this embodiment, and can optimize the heating of the aluminum alloy workpiece.

[0042] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
