Description

Technical Field

[0001] The invention relates to the technical field of cookware production, in particular to a method for producing an energy-saving cookware. Background Art

[0002] An energy-saving pot is a pot that improves thermal energy utilization and reduces energy consumption by optimizing the pot body structure, materials and heating methods. Compared with traditional pots, energy-saving pots usually have the following characteristics: First, the pot body material usually adopts a composite material with excellent thermal conductivity to ensure rapid heating and uniform heating during heating; secondly, energy-saving pots are usually designed with a special pot bottom structure. The energy-saving pot has a beautiful appearance and spiral-shaped heating blades to increase the heating area. It has the characteristics of slow cooling, etc., which maximizes the utilization of thermal energy, thereby achieving the purpose of energy saving and improving the efficiency of thermal energy conduction.

[0003] Chinese Patent (Announcement No.: CN115716123B), the scheme specifically includes a lifting device, a feeding device, a molding device, a discharging device and a detection device. The feeding device is arranged above the molding device. Compared with the current frying pan production device, the present invention is provided with a cooling mechanism and a voltage stabilizing plate. The cooling mechanism can provide kinetic energy for the lifting and lowering of the voltage stabilizing plate. Compared with lifting the frying pan by a push rod and other mechanisms, the present invention lifts the frying pan by a voltage stabilizing plate to increase the contact area between the two as much as possible, avoiding the problem of local deformation of the frying pan due to excessive local force. Finally, the detection mechanism provided in the present invention can synchronously detect the quality of the inner and outer walls of the frying pan from multiple angles without manual displacement, which greatly improves the detection efficiency. At the same time, the present invention can achieve the effect of intelligent classification through the discharging device and the detection device.

[0004] During the casting process of the existing energy-saving pot, whether the gas in the mold cavity is discharged in time will affect the molding quality of the pot. The existing production method is difficult to detect and judge whether the gas is discharged smoothly in time. At the same time, when cooling the pot to be formed in the mold, water cooling is usually adopted, and its cooling effect and cooling degree are difficult to monitor. Insufficient cooling will affect the molding quality of the pot, and excessive cooling will reduce the processing efficiency. Therefore, a production method of an energy-saving pot is proposed.

DETAILED DESCRIPTION

[0059] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] See also Figures 1 to 9 The present invention provides a technical solution: a method for producing an energy-saving pot, comprising the following steps:

[0061] S1. Base material smelting: Select metal materials suitable for casting energy-saving pots. The materials need to have good casting performance, thermal conductivity and durability. Heat the selected metal materials to their melting point to make them completely melted. During the smelting process, control the temperature and add necessary alloy elements to improve the performance of the materials.

[0062] S2, molten material casting: injecting molten metal liquid into the pre-prepared mold 1 to fill the mold cavity 2, and after the casting is completed, cooling the mold 1 and the pot to be formed therein, and at the same time, during the casting process, monitoring the casting quality in real time through a monitoring module provided on the mold 1;

[0063] S3, demoulding and cleaning: after the metal is completely solidified, the casting is taken out of the mold 1, and the casting is cleaned to remove the oxide scale, sand particles, pouring gate and riser parts on the surface to ensure that the surface of the pot is smooth and free of defects;

[0064] S4. Refinement treatment: The cast pots are usually heat treated, and then precision machined to ensure the dimensional accuracy and surface quality of the pots, and then the surface of the pots is treated. Finally, the treated pots are subjected to surface oxidation or nitriding treatment;

[0065] S5. Quality inspection:

[0066] S51, size detection: Use measuring tools to detect whether the size of the cookware meets the design requirements;

[0067] S52. Performance testing: Test the thermal conductivity, non-stick performance and corrosion resistance of the cookware to ensure that the cookware meets production standards.

[0068] S53. Appearance inspection: Conduct a comprehensive inspection of the appearance of the cookware to ensure that it is free of defects and flaws.

[0069] like Figure 1 As shown, a metal material suitable for casting an energy-saving pot is selected. The material must have good casting performance, thermal conductivity and durability to ensure the high efficiency and long service life of the final product. Commonly used metal materials include aluminum alloy or stainless steel. The selected metal material is heated to its melting point to make it completely melted. During the smelting process, the smelting temperature is accurately controlled to avoid deterioration of the material due to overheating. At the same time, appropriate amounts of alloy elements such as copper and magnesium are added as needed to improve the mechanical properties and thermal conductivity of the material. The temperature control and addition of alloy elements in this process are crucial to the quality of the energy-saving pot, so it should be carried out under strict process conditions.

[0070] After the metal material is melted, the molten metal is injected into a pre-prepared mold 1. The mold 1 is made of high-precision materials to ensure the accuracy of the shape of the pot. At this time, the mold 1 needs to have good high temperature resistance and thermal conductivity to ensure that the molten metal can quickly and evenly fill all gaps in the mold 1. During the casting process, the casting quality is monitored in real time by a monitoring module provided on the mold 1 to ensure that there are no casting defects such as pores and shrinkage cavities. After the casting is completed, the mold 1 and the pot to be formed therein are gradually cooled down to allow the molten metal to gradually solidify and take shape. During the cooling process, the cooling rate should be controlled to prevent the generation of internal stress in the metal, thereby ensuring that the internal structure of the pot is uniform and defect-free.

[0071] After the metal is completely solidified, the casting is taken out of the mold 1. During the demoulding process, care should be taken to prevent the casting from being deformed due to mechanical force. After demoulding, the casting is thoroughly cleaned to remove the oxide scale, sand particles, pouring gates and risers on the surface to ensure that the surface of the pot is smooth and free of defects. This step is carried out by combining multiple processes such as mechanical grinding, sand blasting or chemical cleaning to achieve the best cleaning effect and lay a good foundation for subsequent processing steps.

[0072] After casting, the pots and pans usually need to be heat treated to improve the toughness and hardness of the material, eliminate the internal stress generated during the casting process, and ensure that the product has good mechanical properties during use. After heat treatment, the pots and pans need to be precisely processed, including turning, milling and other processes, to ensure that the dimensional accuracy of the pots and pans meets the design requirements and achieves good surface quality. In addition, the surface of the pots and pans is further processed, such as polishing, pickling or spraying, to enhance its anti-corrosion performance and aesthetic appearance. Finally, in order to improve the functionality and durability of the pots and pans, non-stick coating can be applied to their surface to make them more convenient and easy to clean during use.

[0073] At the final stage of production, the cookware undergoes rigorous quality testing, including the following aspects:

[0074] Dimension detection: Use high-precision measuring tools to detect the key dimensions of the cookware, such as the diameter of the bottom of the pot, the depth of the pot, etc., to ensure that it meets the requirements of the design drawings. Ensuring dimensional accuracy is an important prerequisite for ensuring the stable performance of the cookware.

[0075] Performance testing: Comprehensive testing of the cookware's thermal conductivity, non-stick performance and corrosion resistance. The thermal conductivity test can be completed through a heat conduction test, the non-stick performance is tested through a food adhesion test, and the corrosion resistance is evaluated through an acid and alkali resistance test.

[0076] Appearance inspection: Conduct a comprehensive inspection on the appearance of the cookware to observe whether there are scratches, bubbles, blemishes and other defects on its surface. The control of appearance quality not only affects the aesthetics of the product, but also reflects the stability of the production process, ensuring that the cookware meets the standard requirements and is free of flaws and defects.

[0077] Furthermore, the mold 1 is composed of a movable mold and a fixed mold, which together form a mold cavity 2 having the same shape as the cookware, and the mold 1 is provided with a plurality of exhaust holes 3 for exhausting gas in the mold cavity 2. The method for monitoring the casting quality of the molten metal in S2 comprises the following steps:

[0078] S21, exhaust monitoring; the molten substrate enters the mold cavity 2, and the gas in the mold cavity 2 is discharged from the mold 1 through the exhaust hole 3. The gas exhaust factor is detected, and the influence of the gas exhaust amount and exhaust speed on the quality of the pot molding is evaluated according to the gas quality evaluation algorithm;

[0079] S22, cooling monitoring: after casting and molding, the preformed pot in the mold cavity 2 is cooled through the circulating cooling pipe 4 built in the mold 1, and the influence of the cooling factor on the pot molding quality is evaluated according to the cooling quality evaluation algorithm and the gas factor molding quality evaluation value obtained in S21;

[0080] S23. Comprehensive evaluation: Based on the gas factor molding quality evaluation values ​​and the cooling factor molding quality evaluation values ​​obtained in S21 and S22 respectively, the quality evaluation values ​​in the pot casting process are predicted through a comprehensive evaluation algorithm.

[0081] like Figure 1 and Figure 3 As shown, when the molten metal substrate is injected into the mold cavity 2, the original gas in the mold cavity will be discharged from the casting mold 1 through the exhaust hole 3. At this time, by real-time detection of various factors in the gas exhaust process and using the gas quality evaluation algorithm, the influence of these factors on the pot molding quality is analyzed. The smoothness of exhaust is directly related to the density and surface quality of the casting. Therefore, exhaust monitoring is an important link to ensure casting quality.

[0082] After the metal liquid is cast and initially formed, the preformed pot in the mold cavity 2 is cooled by the circulating cooling pipe 4 of the cooling device built into the casting mold 1. During the cooling process, the system will monitor the cooling speed, uniformity, cooling time and other factors in real time based on the cooling quality evaluation algorithm, and combine the gas factor molding quality evaluation value obtained in step S21 to comprehensively evaluate the impact of cooling on the pot molding quality. The temperature gradient and time control during the cooling process are crucial to preventing thermal cracking and deformation of the casting.

[0083] Among them, by inputting the gas factor molding quality assessment value and the cooling factor molding quality assessment value obtained in steps S21 and S22 respectively into the comprehensive assessment algorithm, the casting quality of the entire cookware can be comprehensively predicted and evaluated. This assessment value provides important data support for subsequent quality inspection and improvement, which helps to further optimize the production process and ensure that each piece of cookware meets the expected quality standards.

[0084] In one of the more preferred embodiments, the mold 1 is provided with a measuring structure controlled by both the gas exhaust factor and the cooling factor, the measuring structure comprising a docking groove 9 provided in the mold 1, a pressure sensor 24 freely moving therein according to the gas exhaust factor provided on one side of the docking groove 9, a through groove 13 communicating with the docking groove 9 provided on the mold 1, a connecting rod 29 corresponding to the pressure sensor 24 and freely moving due to the cooling factor provided in the through groove 13;

[0085] The pressure sensor 24 is not in contact with the connecting rod 29 in the initial state. A data receiving and processing module electrically connected to the pressure sensor 24 is fixedly connected to the mold 1. The data receiving and processing module is also remotely electrically connected to a terminal module.

[0086] like Figure 1 and Figure 3 As shown, when the molten base material is cast into the mold cavity 2, the gas in the mold cavity 2 is gradually discharged, wherein the gas discharge process drives the pressure sensor 24 to move toward the connecting rod 29, wherein, under the influence of the gas factor, the pressure sensor 24 moves toward the connecting rod 29 and presses against the connecting rod 29. At this time, the pressure value received by the pressure end of the pressure sensor 24 is Q1, and the pressure sensor 24 transmits the pressure signal received to the signal receiving and processing module in real time. After receiving the pressure signal, the signal receiving and processing module analyzes and processes it according to the time module set thereon and the time of injecting the molten base material, and remotely transmits the processed signal result to the terminal module through the wireless transmission module.

[0087] When casting is completed and the mold 1 is cooled, cooling water is circulated in the circulating cooling pipe 4 to achieve the purpose of first lowering the temperature of the mold 1 and then lowering the temperature of the pot to be formed. At the same time, when the temperature of the mold 1 is reduced to the set value, the docking groove 9 can move downward and finally push the pressure sensor 24 to return to the initial position. In the process of pushing the docking groove 9 to the initial position, the maximum pressure value received by the docking groove 9 is Q2. The signal receiving and processing module receives the pressure signal of the pressure sensor 24 and processes it. After the Q2 value reaches the set value, it means that the set cooling purpose has been achieved. At this time, it means that the cooling process of the pot in the mold 1 is completed, thereby avoiding insufficient cooling to affect the molding quality, and also avoiding excessive cooling to reduce the processing efficiency.

[0088] Furthermore, the measuring structure includes a gas collecting channel 5 opened on the mold 1, the gas collecting channel 5 and the multiple groups of exhaust holes 3 are gas-connected, the gas collecting channel 5 includes an integrally formed narrow mouth portion 6, and the mold 1 is provided with multiple groups of micro-diameter channels 7 gas-connected with the narrow mouth portion 6;

[0089] The mold 1 is provided with a head end guide groove 10 communicating with the docking groove 9, and a spring sheet 14 is provided at one end of the head end guide groove 10 away from the docking groove 9. The mold 1 includes an integrally formed sealing step portion 102, and the spring sheet 14 is fixedly connected to the sealing step portion 102. A closed air cavity 8 communicating with the gas between the plurality of micro-diameter channels 7 is formed between the spring sheet 14 and the mold 1.

[0090] A guide column 21 that moves freely according to the deformation of the spring sheet 14 is provided in the head end guide groove 10 , and one end of the guide column 21 facing the docking groove 9 is fixedly connected to the pressure sensor 24 .

[0091] The spring sheet 14 is fixedly connected with a positioning column 15, and the outer ring of the positioning column 15 is provided with a positioning spring 16. The two ends of the positioning spring 16 are respectively fixedly connected to the mold 1 and the spring sheet 14. The mold 1 is provided with a positioning circular hole 11 for the positioning column 15 to be slidably connected.

[0092] A guide column 21 is slidably connected in the head end guide groove 10, and a hollow end frame 18 is fixedly connected to the end of the guide column 21 facing the spring sheet 14. The hollow end frame 18 is provided with multiple groups of side limit balls 19, and a ball groove 20 for the side limit balls 19 to slide is provided. The mold 1 is provided with an integrally formed inner step portion 101 at the position corresponding to the side limit ball 19. The spring sheet 14 is fixedly connected to the side of the hollow end frame 18 with a latch 17 that contacts the side limit ball 19. The latch 17 includes an integrally formed tip portion 171.

[0093] The mold 1 is fixedly connected with a column sleeve 23, which is provided with a round hole for the guide column 21 to slide through. The outer ring of the guide column 21 is provided with a pressure spring 22, and the two ends of the pressure spring 22 are respectively fixedly connected to the column sleeve 23 and the hollow end frame 18.

[0094] like Figure 2-Figure 7 As shown, as the molten substrate is gradually injected into the mold cavity 2, the gas in the mold cavity 2 is gradually squeezed into the gas collecting channel 5 through the exhaust hole 3, wherein the gas collecting channel 5 includes an integrally formed narrow mouth portion 6, and the gas flow diameter at the narrow mouth portion 6 is smaller than the gas flow diameter at the gas collecting channel 5. Under the Venturi effect, the Venturi effect is expressed as follows: when the fluid passes through the tightened channel, the flow rate will increase, and its size is inversely proportional to the cross-section of the tightening portion. Therefore, when the gas passes through the narrow mouth portion 6, the cross-sectional size of the narrow mouth portion 6 becomes smaller, so the flow rate here will increase, and under the Bernoulli effect, low pressure will be generated near the highly flowing fluid. Therefore, when the gas is discharged through the gas collecting channel 5, it will cause low pressure to be generated in the micro-diameter channel 7, and guide the low pressure to the closed air cavity 8, so as to cause the gas in the closed air cavity 8 to be discharged into the gas collecting channel 5, thereby causing the spring 14 to deform.

[0095] At the same time, in the initial state, the pressure spring 22 is in a stretched state. When the spring sheet 14 is deformed due to the negative pressure in the closed air cavity 8, the latch 17 thereon is driven to move downward, thereby causing the latch 17 to detach from the position of the hollow end frame 18. In the initial state, the latch 17 is in contact with the side limiting ball 19, and is restricted by the inner step 101 on the side limiting ball 19, causing the pressure spring 22 to be unable to restore its deformation. However, when the latch 17 is separated from the position of the hollow end frame 18, the side limiting ball 19 will no longer be restricted by the inner step 101. At this time, the pressure spring 22 can restore its deformation and drive the guide column 21 to drive the pressure sensor 24 arranged thereon to move upward, thereby causing the pressure sensor 24 to detach from the connecting rod 29. At this time, the pressure value at the pressure sensor 24 is Q1.

[0096] Among them, since the molten substrate is injected into the mold cavity 2, if the gas in the mold cavity 2 is not discharged in time, the limiting time of the side limiting ball 19 by the pin 17 will be extended, thereby increasing the time interval from the start of pouring the substrate to the triggering of Q1. At the same time, if during the continuous pouring process, the pin 17 has not completed the limiting process of the side limiting ball 19, it means that the gas discharge amount in the mold cavity 2 is too small at this time. Therefore, the residual gas in the mold cavity 2 will have an adverse effect on the quality of the cast pot.

[0097] Among them, the gas quality assessment algorithm is as follows: Q1 quality =P init +(V g / T Q1 )*α, in this formula:

[0098] Q1 quality : Expressed as the molding quality evaluation value of the gas factor;

[0099] P init : represents the initial pressure value, i.e., the pressure of the mold cavity (2) before injection into the mold (1);

[0100] V g : Expressed as the volume of gas that needs to be discharged;

[0101] T Q1 : represents the trigger time of Q1;

[0102] α: It is expressed as a calibration coefficient, which is used to adjust the degree of influence of gas flow on Q1. It depends on the specific casting process and mold 1 design. The value of α is determined by experimental data. Specifically, the relationship between gas discharge and casting quality under different conditions can be measured through multiple experiments, and then the optimal value of α can be determined by regression analysis or other statistical methods.

[0103] The value of α usually ranges from 0.1 to 10, depending on the actual effect of gas flow on molding quality. If the gas flow has a greater impact on molding quality, the value of α may be higher, otherwise it may be lower;

[0104] Q1 represents the pressure value when the pressure sensor 24 is in contact with the positioning sleeve 25 under the gas factor.

[0105] Furthermore, the measuring structure also includes a terminal orientation groove 12 opened on the mold 1 and communicating with the through groove 13, a positioning sleeve 25 fixedly connected to the mold 1 is arranged in the terminal orientation groove 12, and the positioning sleeve 25 includes an integrally formed open portion 251, and a heat conducting plate 27 fixedly connected to the mold 1 is arranged in the open portion 251;

[0106] The positioning sleeve 25 is provided with an isotropic column 26, and the outer peripheral surface of the isotropic column 26 is in sliding contact with the inner wall of the positioning sleeve 25. A temperature memory alloy 28 is fixedly connected to the heat conducting plate 27, and one end of the temperature memory alloy 28 away from the heat conducting plate 27 is fixedly connected to the isotropic column 26, and one end of the isotropic column 26 away from the temperature memory alloy 28 is fixedly connected to the connecting rod 29.

[0107] like Figure 3 , Figure 8 and Fig. 9 As shown, when the mold 1 and the pot to be formed therein are cooled, the temperature of the mold 1 will decrease under the action of the circulating water source, and the temperature of the mold 1 can be transferred to the temperature memory alloy 28 through the heat conduction plate 27 arranged in the open part 251. When the temperature is cooled to the set temperature, the temperature memory alloy 28 can restore the deformation and drive the connecting rod 29 to move downward through the isotropic column 26.

[0108] Among them, Fig. 9 As shown, under the influence of the previous gas factor, the pressure spring 22 recovers its deformation from the compressed state, that is, the initial height of the pressure sensor 24 is H1. When the pressure spring 22 recovers its deformation, it prompts the pressure sensor 24 to move upward to the H2 position. At this time, the pressure value received by the pressure sensor 24 is Q1.

[0109] However, as the cooling process proceeds, the temperature memory alloy 28 deforms and drives the connecting rod 29 to move downward. At this time, the connecting rod 29 drives the pressure sensor 24 to move downward synchronously and prompts the pressure sensor 24 to move from the H2 position to the H1 position. It should be noted that during the casting process, as the gas in the mold cavity 2 is discharged, negative pressure occurs in the closed air cavity 8. However, as the casting is completed, under the action of the positioning spring 16, the spring clip 14 returns to its initial position and allows the pin 17 to extend into the hollow end frame 18 again.

[0110] At the same time, under the action of cooling factors, the guide column 21 moves downward and drives the hollow end frame 18 to move downward synchronously. At this time, until the side limiting ball 19 is pushed by the hollow end frame 18 to contact the tip 171 in the latch 17, at this time, as the guide column 21 continues to move, the latch 17 moves downward synchronously with the hollow end frame 18 until the side limiting ball 19 corresponds to the position of the inner step 101, and the connecting rod 29 also moves to the H2 position. In the process of the downward movement of the latch 17, the positioning spring 16 is partially compressed and deformed. However, when the side limiting ball 19 corresponds to the position of the inner step 101, under the elastic potential energy of the pressure spring 22, the latch 17 can return to its initial position and limit the side limiting ball 19 again, thereby realizing the reset process of the latch 17 and the side limiting ball 19.

[0111] At the same time, when the connecting rod 29 moves from the H2 position to the H1 position, it will first drive the pressure spring 22 to undergo compression deformation, and then drive the positioning spring 16 to undergo a slight compression deformation until the positioning spring 16 recovers its deformation. During this process, the maximum pressure value received by the pressure sensor 24 is Q2.

[0112] It should be noted that when the molten substrate is subsequently poured into the mold cavity 2, the temperature of the molten substrate is relatively high, which can drive the temperature memory alloy 28 to deform at a higher temperature, so as to prompt the isotropic column 26 to drive the connecting rod 29 to move upward, that is, drive the connecting rod 29 to return to the H2 position from the H1 position. At this time, the pressure sensor 24 is no longer in contact with the connecting rod 29 until the gas factor prompts the pin 17 to complete the unlocking process of the side limit ball 19.

[0113] Among them, the cooling quality evaluation algorithm is as follows: Q2 quality =ν*Q1 quality +(T Q2 / T total )*β, in this formula:

[0114] T Q2 : represents the trigger time of Q2, which indicates the time when the connecting rod (29) moves during the cooling process;

[0115] T total : The total time of the entire casting and cooling process;

[0116] ν: expressed as a weight coefficient, used to adjust Q1 quality Impact on overall quality;

[0117] β: expressed as a calibration coefficient related to Q2, used to adjust the impact of Q2;

[0118] Q2 quality: It is expressed as the molding quality evaluation value of the cooling factor;

[0119] Meanwhile, Q2 represents the maximum pressure value exerted on the pressure sensor 24 when the coupling rod 29 pushes the pressure sensor 24 to return to the initial position under the cooling factor.

[0120] It should be noted that β is the calibration coefficient in the cooling quality evaluation algorithm, which is used to adjust the effect of cooling time on molding quality. Cooling rate and cooling uniformity are crucial in preventing hot cracking and deformation of castings. Therefore, β optimizes the accuracy of the evaluation value by adjusting the weight of cooling time in the overall quality evaluation. The optimal value of β is determined by experimental methods. The relationship between cooling time and casting quality under different cooling conditions can be measured experimentally, and then the optimal β value is determined by regression analysis. The numerical range of β is generally between 0.5 and 5, which depends on the actual influence of the cooling process on the molding quality. If the cooling time has a significant effect on the molding quality, the value of β may be higher, otherwise it is lower.

[0121] Where ν is used to balance Q1 quality and T Q2 The contribution ratio in the overall quality assessment, the value of ν can be adjusted through experimental data.

[0122] Furthermore, the comprehensive evaluation algorithm is specifically as follows:

[0123] Q quality =θ1*Q1 quality +θ2*Q2 quality ;

[0124] Among them, θ1 and θ2 are both expressed as weight coefficients, which are determined through actual production tests, including quality data during molten iron injection, quality data during cooling, and quality evaluation results of the final product. Through these data, statistical analysis methods can be used to estimate θ1 and θ2 so that the error between the predicted quality evaluation value and the actual quality result is minimized. The numerical range of θ1 and θ2 is usually between 0 and 1, and their sum is 1, that is, θ1+θ2=1, which means that the contribution of gas and cooling factors to the final quality evaluation may be balanced, or one of the factors may dominate.

[0125] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
