Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal heat treatment devices, in particular to a metal surface heat treatment device with self-diagnosis function and a processing method. BACKGROUND

[0002] Metal materials are widely used in aerospace, automobile manufacturing, mechanical engineering, electronic equipment and many other fields as the cornerstone of modern industry. The performance of metal materials directly determines the quality, reliability and service life of products. Metal surface heat treatment, as an important metal processing technology, can significantly improve the performance of metal surfaces and plays a key role in improving the overall performance of metal materials. Metal surface heat treatment changes the microstructure and chemical composition of the metal surface through heating, holding and cooling, thereby imparting special properties to the metal surface that are different from the base material. For example, quenching can make the metal surface have high hardness and wear resistance, effectively resisting wear and tear, and prolonging the service life of parts. Chemical heat treatment processes such as carburizing and nitriding can form a layer of high-hardness, corrosion-resistant compound on the metal surface, enhancing the corrosion resistance of the metal in harsh environments.

[0003] The prior art also has many deficiencies when in use. After the metal original piece is initially processed, a certain amount of cooling liquid will remain on its surface. When the heat of the metal itself is transferred to the surrounding cooling liquid, the local cooling liquid temperature will rise, thereby triggering a series of chemical reactions, and eventually forming volatile organic mist on the liquid surface. In the early stage of the formation of the organic mist, the existing equipment cannot timely detect this change and cannot issue an alarm or start the corresponding processing program in the first time. Moreover, it cannot accurately target the treatment according to the specific concentration and chemical properties of the organic mist. In fact, the concentration of the organic mist has a huge difference in the impact on metal processing. When the concentration of the organic mist is within a suitable range, it can participate in the formation of a uniform oxide film, which can effectively alleviate the thermal stress generated during the subsequent processing of the metal and reduce the risk of cracks during quenching, thereby positively affecting the quality of the metal finished product. However, if the concentration of the organic mist is too high, it will change the atmospheric composition and physical and chemical properties around the workpiece and destroy the stable environment required for the formation of the oxide film. At this time, the existing technology lacks the ability to self-diagnose the concentration change and automatically adjust the processing method, making it difficult for the oxide film to be completely and uniformly generated, which greatly reduces the cooling effect of the metal and seriously affects the quality of the product. In addition, the excessive organic mist that has already been generated has many hazards. In the metal processing workshop, high-concentration organic mist will diffuse in the air, interfering with the operator's vision and affecting their observation and judgment of the equipment operation status and metal processing process. At the same time, these mists may adhere to the key components of the equipment, corrode precision instruments, and reduce the service life and precision of the equipment. SUMMARY

[0015] Compared with the prior art, the beneficial effects of the present application are:

[0016] 1. In the present scheme, by setting the detection component, the organic mist is accurately detected and dynamically controlled, when working, the suction fan in the suction box body continuously rotates, and the organic mist is extracted from the surface of the cooling liquid, the mist first enters the infrared spectrometer detection area, and the concentration is monitored in real time, when the concentration is appropriate, the mist is discharged from the opening on the upper surface of the suction box body after passing through the partition plate, and is sprayed on the surface of the quenched metal element through the top gas conveying pipe, forming an oxidation film to relieve thermal stress and improve cooling uniformity, when the metal element is immersed for a long time, the concentration of the organic mist is too high, the infrared spectrometer sends a prompt signal to the control device, drives the sealing plate to overturn and close the opening, and starts the internal air pump to suck the mist into the transfer cavity, at this time, the color and odor detection assembly carries out secondary detection on the color and odor of the mist, and sends a signal to the control device according to the detection result, so as to provide a basis for selecting a processing method for subsequent processing components, through multi-stage detection and intelligent linkage, the dynamic monitoring and accurate classification of the organic mist are realized.

[0017] 2. In this scheme, by setting the processing components, the processing path is automatically switched according to the characteristics of the organic mist, realizing efficient purification and resource recycling. When the color detection component determines that the mist needs to be condensed, the control device drives the small motor to rotate, and the sliding plate body moves through the meshing effect of the meshing screw and the meshing block. The airway to the condensation cavity is opened, and the mist enters the condensation cavity and flows through the condensation plate under the traction of the suction box body. The refrigeration temperature plate and the refrigeration fan maintain the low temperature of the condensation plate. The temperature guide metal strip conducts the low temperature of the cooling immersion pool to the condensation plate to assist refrigeration. The mist condenses after contacting the condensation plate, and the gaseous rust inhibitor condenses into liquid and falls into the receiving pool for collection. When the mist needs to be catalytically decomposed, the sliding plate body moves to open the airway to the catalytic decomposition cavity, and the mist enters the regenerative catalytic oxidizer through the transmission branch pipe. The internal catalyst decomposes harmful substances into carbon dioxide and water vapor. Finally, the gas enters the gas storage cylinder through the connecting branch pipe for storage. After the equipment runs for a long time, the return gas pump starts to inject carbon dioxide and water vapor in the gas storage cylinder into the cooling liquid. The weak acid environment formed by carbon dioxide inhibits bacterial reproduction, prolonging the service life of the cooling liquid. Water vapor condenses to form a lubricating film, reducing the friction resistance between the workpiece and the cooling liquid, and avoiding local overheating. This dual-mode processing technology realizes the precise purification and resource recycling of organic mist.

[0018] 3. In this scheme, by setting the feeding components, the automatic and precise conveying and quenching position switching of the metal original piece are realized. During work, the worker places the metal original piece on the feeding conveyor belt in order. The conveyor belt conveys it to the discharging slide and stops. The internal telescopic rod extends to push the arc block to push the metal original piece to the surface of the arc ring plate. At this time, the telescopic cylinder extends to make the arc ring plate lose the top touch of the connecting frame body and slide down along the limiting side groove. The metal original piece is sleeved on the outer surface of the limiting rod body to prevent it from falling off. The telescopic cylinder drives the limiting rod body to rise, so that the metal original piece enters the effective circle center for quenching. After quenching, the telescopic cylinder descends, the arc ring plate is touched by the processing box body and slides up along the limiting side groove, and the limiting rod body exits from the center of the metal original piece. At this time, the water pipe sprays cooling liquid on the metal original piece through the pre-cooling water ring to pre-cool it. At the same time, when the arc ring plate descends to the position of the connecting frame body, the trigger button is pressed to send a signal to the control device to drive the internal telescopic rod to extend again, so as to push out the new metal original piece and replace the position of the quenched metal original piece, so that it falls into the cooling immersion pool for cooling. The continuous and automatic conveying and quenching position switching of the metal original piece are realized, the manual operation error is avoided, and the production efficiency and quenching quality are improved.

[0029] Embodiment 1: Please refer toFigures 1 to 8 A metal surface heat treatment device with self-diagnosis function and treatment method, comprising:

[0030] The upper surface of the main base 1 is further provided with a power supply box 6, one side surface of the power supply box 6 is provided with an effective ring 7, the upper surface of the main base 1 is provided with a cooling immersion tank 2, the inside of the cooling immersion tank 2 is provided with a telescopic cylinder 9, the output shaft end of the telescopic cylinder 9 is provided with a limiting rod body 42, the outer surface of the limiting rod body 42 is provided with an arc ring plate 43 for carrying metal elements, the side surface of the limiting rod body 42 is provided with a limiting side groove 44 for facilitating the sliding of the arc ring plate 43, the upper surface of the cooling immersion tank 2 is further provided with two top fixed strips 3, the two top fixed strips 3 are provided with a pre-cooling water outlet ring 4, one side surface of the pre-cooling water outlet ring 4 is provided with a water pipe 5, the water pipe 5 is located directly above the telescopic cylinder 9, the upper surface of the main base 1 is further provided with an auxiliary mechanism, the auxiliary mechanism includes a material conveying part and a gas collecting assembly, the material conveying part includes: a conveying frame body 8, the conveying frame body 8 is arranged on the upper surface of the cooling immersion tank 2, the upper surface of the conveying frame body 8 is provided with a feeding conveyor belt 36, the upper surface of the conveying frame body 8 is further provided with an internal telescopic rod 38, the output shaft end of the internal telescopic rod 38 is provided with a pushing arc block 39, the upper surface of the internal telescopic rod 38 is provided with a discharging slide 37, the inside side surface of the cooling immersion tank 2 is further provided with two connecting frame bodies 40, the upper surface of the connecting frame body 40 is provided with two trigger buttons 41 matched with the arc ring plate 43, the trigger button 41 and the internal telescopic rod 38 are electrically connected;

[0031] In use, the device is used to transport annular metal components (such as metal shafts) for quenching in the heat treatment process. Before use, the operator connects one end of the water pipe 5 to the cooling liquid storage device. Then, the operator places a plurality of metal components in sequence on the upper surface of the feeding conveyor belt 36, and the metal components are transported by the feeding conveyor belt 36. When the frontmost metal component is separated from the upper surface of the feeding conveyor belt 36 and slides down the discharging chute 37 to the prepared position, the feeding conveyor belt 36 stops. At this time, the operator controls the internal telescopic rod 38 to extend by a signal, and the metal component is pushed out by the pushing arc block 39 to reach the upper surface of the arc ring plate 43. After the metal component is transported to the upper surface of the arc ring plate 43 by the feeding conveyor belt 36, the feeding conveyor belt 36 is transported again to make the next metal component reach the prepared position. The telescopic cylinder 9 extends at this time, and the arc ring plate 43 loses the top touch effect of the upper surface of the connecting frame body 40. The limiting rod body 42 is exposed by sliding downward in the limiting side groove 44. At this time, the metal component is sleeved on the outer surface of the limiting rod body 42 to prevent it from falling off. As the telescopic cylinder 9 drives the limiting rod body 42 to rise, the metal component enters the center of the effective ring 7. Then, the effective ring 7 is powered by the power supply box 6, and the surface of the metal component is quenched by the effective ring 7. Then, the telescopic cylinder 9 drives the limiting rod body 42 and the metal component to descend back to the original position. When the limiting rod body 42 and the arc ring plate 43 are lowered to a certain extent, the arc ring plate 43 is subjected to the top touch effect of the upper surface of the processing box 10, and slides upward in the limiting side groove 44. At this time, the limiting rod body 42 gradually exits from the center of the metal component. At this time, the cooling liquid is transported by the water pipe 5, and is sprayed on the surface of the metal component by the water outlet of the pre-cooling water ring 4 to pre-cool the metal component. After the metal component is pre-cooled, a certain amount of cooling liquid remains on the surface of the metal component, which contains a key antirust agent component. When the heat of the metal component is transferred to the surrounding cooling liquid, the temperature of the local cooling liquid will rise, thereby triggering a series of chemical reactions, and finally forming volatile organic mist on the liquid surface. When the arc ring plate 43 is subjected to the top touch effect of the upper surface of the connecting frame body 40, the trigger button 41 is pressed. After the trigger button 41 is triggered, the internal telescopic rod 38 is automatically driven to extend once, so that the new metal component is ejected. The quenched metal component is ejected by the new metal component, and replaces its position. The quenched metal component is ejected from the upper surface of the arc ring plate 43 and falls into the cooling immersion tank 2. Because the cooling immersion tank 2 is filled with cooling liquid, the metal component is cooled after falling into the cooling tank. After cooling, the operator can take out the metal components in the cooling immersion tank 2.

[0032] The gas collecting assembly is composed of a detection component and a processing component, and includes a side base 13, one side surface of which is connected with one side surface of the main base 1, and an upper surface of the side base 13 is provided with a processing box body 10, the detection component and the processing component are both located inside the processing box body 10, the detection component includes a connecting air pipe 24, which is arranged on one side surface of the processing box body 10 and is located inside the cooling immersion pool 2, one end of the connecting air pipe 24 is provided with a suction box body 11, the inside of the suction box body 11 is provided with an infrared spectrometer 52, the inside of the suction box body 11 is further provided with a partition plate 55, the center of the partition plate 55 is provided with a suction fan 56, the inside bottom surface of the suction box body 11 is further provided with a limiting sealing plate 54, the inside upper surface of the suction box body 11 is further provided with a sealing plate 53 matched with the limiting sealing plate 54, the connecting position between the sealing plate 53 and the inside of the suction box body 11 is provided with an electric shaft, the upper surface of the suction box body 11 is provided with an opening, the upper surface of the opening is provided with a top air pipe 15, the detection component further includes an internal air pump 23, one end of the internal air pump 23 is connected with one end of the connecting air pipe 24, the inside of the processing box body 10 is provided with a transfer cavity 20, the other end of the internal air pump 23 is communicated with the inside of the transfer cavity 20, the inside side surface of the processing box body 10 is provided with a color and flavor detection assembly 21, the inside bottom surface of the transfer cavity 20 is further provided with a transfer box body 22, one side surface of the transfer box body 22 is provided with a secondary air pump 29, the other end of the secondary air pump 29 is connected with the inside of the transfer box body 22, the inside of the transfer box body 22 is provided with a sliding plate body 32, the inside bottom surface of the transfer box body 22 is provided with a bottom sliding groove 35 for facilitating the sliding of the sliding plate body 32, the inside of the transfer box body 22 is further provided with a limiting fixed plate 34 for limiting the moving distance of the sliding plate body 32, the upper surface of the sliding plate body 32 is provided with an engaging block body 33, the upper surface of the transfer box body 22 is provided with a small-sized motor 30, the output end of the small-sized motor 30 is provided with an engaging screw rod 31 engaged with the engaging block body 33, two ends of the transfer box body 22 are respectively communicated with two cavities of the processing component;

[0033] When the metal workpiece is immersed in the cooling liquid in the cooling tank after quenching, the surface of the metal workpiece will have some cooling liquid used for pre-cooling. When the metal workpiece is immersed in the cooling liquid in the cooling tank, the antirust agent in some cooling liquid remaining on the surface of the metal workpiece will react with the cooling liquid with a higher temperature due to the remaining temperature of the metal workpiece, and volatile organic mist will be generated on the upper surface of the liquid. The gas collection assembly extracts and collects the organic mist, and different treatment methods are selected according to the properties of the organic mist. The detection component in the gas collection assembly is used for collecting and detecting the organic mist. When in use, the suction fan 56 in the suction box body 11 rotates to suck the generated organic mist from the surface of the cooling liquid into the inside of the suction box body 11. After the organic mist enters the inside of the suction box body 11, it is first detected by the infrared spectrometer 52. When the concentration of the organic mist is appropriate, the organic mist passes through the infrared spectrometer 52 and the partition plate 55, passes through the opening on the upper surface of the suction box body 11, and is conveyed by the top gas conveying pipe 15, and finally sprayed on the surface of the metal workpiece being quenched to form a stable mist curtain covering the surface of the metal workpiece. After the organic mist is sprayed on the surface of the metal workpiece, an oxide film is formed. During the quenching and cooling process, the cooling speed of the surface and the inside of the metal workpiece is different, which will generate a large thermal stress. The existence of the oxide film can relieve the thermal stress to a certain extent. Because the thermal expansion coefficient of the oxide film is different from that of the base metal of the metal workpiece, during the cooling process, the contraction or expansion of the oxide film will interact with the base metal of the metal workpiece to a certain extent. This interaction can absorb and disperse part of the thermal stress, so that the stress distribution in the workpiece is more uniform, thereby reducing the risk of quenching cracks. Moreover, the heat generated in the coil heating area can be quickly taken away, the heat exchange efficiency is improved, the cooling time after austenitizing is shortened, and the formation of martensite is promoted. During the pre-cooling stage, the cooling uniformity can be significantly improved. After a long time of use, after multiple metal workpieces are immersed in the inside of the cooling liquid, the generated organic mist will gradually accumulate. Too much organic mist will change the atmospheric composition and physical and chemical properties around the workpiece, destroy the stable environment required for the formation of the oxide film, and make it difficult for the oxide film to be completely and uniformly formed. Therefore, when the concentration of the organic mist reaches an inappropriate degree for auxiliary processing, the infrared spectrometer 52 sends a prompt signal to the control device in the hand of the worker, and the control device automatically sends a control signal to drive the electric shaft on the upper surface of the sealing plate 53 to rotate and drive the sealing plate 53 to flip to block the opening on the upper surface of the suction box body 11. At this time, the organic mist will not enter the inside of the top gas conveying pipe 15 through the opening.The organic mist is extracted into the inside of the processing box body 10 by the internal air pump 23, and after being extracted by the internal air pump 23, the organic mist is discharged into the inside of the transfer cavity 20. At this time, the color and smell of the organic mist are detected by the color and smell detection assembly 21 on the inner side surface of the transfer cavity 20. The color and smell detection assembly 21 is composed of a smell detector and a mist detector, which are used to reasonably detect the organic mist and select two different processing methods of processing components according to the characteristics of the organic mist.

[0038] When the quenched metal element is immersed in the cooling liquid, the antirust agent in the surface residual cooling liquid reacts with the heated cooling liquid to generate organic mist at the liquid surface. The suction box body 11 of the gas collection assembly rotates the suction fan 56 to suck the organic mist. When the concentration is appropriate, the mist is detected by the infrared spectrometer 52, and then sprayed on the surface of the quenched metal element through the top gas pipe 15 to form an oxide film, so as to relieve thermal stress and reduce the risk of quenching cracks.
