Description

Technical Field

[0001] The present invention relates to the field of automotive springs, and particularly to a quenching treatment device for processing automotive leaf springs. Background Art

[0002] Automotive leaf springs are a common vehicle suspension component, mainly used to support the vehicle body weight and absorb shocks and vibrations from the road surface. They are composed of multiple steel plates stacked together and fixed between the vehicle frame and axle through bolts or other connection methods.

[0003] In the processing of automotive leaf springs, quenching treatment is a very crucial step. Quenching is to heat the steel plate to a certain temperature and then rapidly cool it to improve the hardness and strength of the material. For the quenching treatment of leaf springs, specific equipment is required.

[0004] However, in the existing quenching treatment equipment for automotive leaf springs, during the quenching process in the quenching pool, due to the different contact times between the leaf springs and the quenching liquid, the local temperature in the quenching pool also varies. Uneven cooling of the temperature will cause stress imbalance on the surface and inside of the steel parts, easily generating cracks at the vulnerable parts of the steel parts and reducing their service life.

[0005] Moreover, in the traditional quenching treatment equipment, after long-term use, the temperature of the quenching liquid gradually increases. Temperature control often relies on operators observing the temperature indicating mechanism and manually adjusting the quenching liquid when the temperature reaches the threshold. The adjustment accuracy is low and it is difficult to timely adjust the quenching environment. Summary of the Invention

[0006] The purpose of the present invention is to provide a quenching treatment device for processing automotive leaf springs to solve the technical defects proposed in the background art.

[0007] The purpose of the present invention can be achieved through the following technical solutions: A quenching treatment device for processing automotive leaf springs includes a fixed frame, in which a cavity one and a cavity two are provided. Guide frames and quenching components are fixedly installed in both the cavity one and the cavity two.

[0008] The quenching component includes a fixed pipe, a pump body, and a spray head. The pump body and the fixed pipe are both fixedly installed on both sides of the fixed frame. The pump body is fixedly connected to the fixed pipe through a pipeline. A plurality of spray heads are fixedly installed on one side of the fixed pipe, and the spray heads are located on one side of the guide frame.

[0009] The quenching component further includes an airbag, a moving frame, and a wind guide box. A through groove is opened on the fixed frame, and the wind guide box is fixedly installed at the through groove. The moving frame is movably installed in the fixed frame. The moving frame is located at one end of the guide frame. The airbag is fixedly installed on one side of the fixed frame. The airbag is fixedly connected to the wind guide box through a pipeline. A moving plate is movably installed on one side of the fixed frame, and the moving plate is fixedly connected to the airbag.

[0010] A sliding frame is movably installed on one side of the fixing frame away from the airbag, a blanking plate is movably installed in the sliding frame, and a control panel is fixedly installed on one side of the fixing frame.

[0011] Preferably, a first lead screw is movably installed on one side of the fixing frame, a first moving nut is movably installed on the first lead screw through a thread, the first moving nut is fixedly connected to the sliding frame, and one end of the blanking plate is movably connected to the sliding frame through a rotating shaft.

[0012] Preferably, an electric push rod is fixedly installed in the sliding frame, the output end of the electric push rod is movably connected to the blanking plate, sliding grooves are formed on both sides of the sliding frame, sliding blocks are fixedly installed on both sides of the blanking plate, and the sliding blocks are movably installed in the sliding grooves.

[0013] Preferably, a second lead screw is movably installed in the fixing frame, a second moving nut is movably installed on the second lead screw through a thread, the second moving nut is fixedly connected to the moving frame, and a first synchronous pulley is fixedly installed at the bottom of the second lead screw.

[0014] Preferably, a third lead screw is movably installed at one end of the fixing frame away from the second lead screw, a second synchronous pulley is fixedly installed at the bottom of the third lead screw, the first synchronous pulley is in transmission connection with the second synchronous pulley through a synchronous belt, a third moving nut is movably installed on the third lead screw through a thread, and the third moving nut is fixedly connected to the moving plate.

[0015] Preferably, the control panel includes a server, a temperature monitoring module, an impurity monitoring module and a remote supervision terminal;

[0016] The temperature monitoring module monitors the quenching environment in Chamber One and Chamber Two, generates a normal temperature signal or a temperature anomaly signal through process analysis, and sends the temperature anomaly signal to the remote supervision terminal through the server;

[0017] The impurity monitoring module monitors the impurity concentration of the quenching liquid in Chamber One and Chamber Two, generates a deviation value through process analysis, compares and processes the deviation value to generate a qualified impurity signal or an impurity anomaly signal, and sends the impurity anomaly signal to the remote supervision terminal through the server;

[0018] When the remote supervision terminal receives a temperature anomaly signal or an impurity anomaly signal, it immediately controls the sliding frame to work and issues a corresponding warning.

[0019] Preferably, the specific operation process of the temperature monitoring module includes:

[0020] The quenching liquid temperature data of Chamber One and Chamber Two are respectively collected, and the average value of all the quenching liquid temperature data within a unit time is calculated to obtain a temperature inspection value. If the temperature inspection value is greater than a preset temperature inspection threshold value, a temperature anomaly signal is generated.

[0021] Preferably, the specific operation process of the impurity monitoring module includes:

[0022] The impurity data of the quenching liquid inside Chamber 1 and Chamber 2 are collected. The average value of all impurity concentration data per unit time is calculated to obtain the impurity concentration value. With time as the X-axis and the collected impurity concentration value data as the Y-axis, a coordinate system is constructed. The impurity concentration data per unit time are marked on the coordinate system, and the thresholds set for the corresponding data types are plotted on the coordinate system.

[0023] If the impurity concentration data fluctuates, it will show an upward float on the coordinate system. That is, the area of the floating waveform deviation region between the impurity concentration data curve and the threshold curve is calculated. The area of the floating waveform deviation region per unit time is the deviation value.

[0024] If the deviation value exceeds the set threshold and continues to increase, it is inferred that there is an abnormality in the quenching liquid in the current corresponding chamber. Then an impurity abnormality signal is generated, and the impurity abnormality signal is sent to the remote supervision terminal through the server.

[0025] The beneficial effects of the present invention are as follows:

[0026] (1) Through the linkage and cooperation of components such as the fixed pipe, pump body, and nozzle, the present invention first conveys the quenching liquid into the fixed frame, and the liquid level is flush with the top of the guiding frame. At this time, the leaf spring to be quenched is conveyed onto the guiding frame. Under the action of gravity, the leaf spring slides on the guiding frame. During the sliding process, the leaf spring is quenched by the quenching liquid. At the same time, the pump body is started to extract the quenching liquid at the bottom of Chamber 1 or Chamber 2 into the fixed pipe and spray it out through the nozzle. On the one hand, it improves the bottom quenching liquid to avoid uneven temperature in Chamber 1 or Chamber 2. On the other hand, an axial water flow is formed through the nozzle to form a turbulent flow on the leaf spring, increasing the contact time between the liquid and the leaf spring and effectively improving the quenching efficiency.

[0027] (2) Through the linkage and cooperation of components such as the airbag, moving frame, and air guide box, after the quenching of the leaf spring is completed, the moving frame is used to drive the leaf spring to move upward. During the upward movement, the moving plate squeezes the airbag, and the gas enters the air guide box and is blown towards the liquid surface through the air guide box. The high-speed air flow is used to push the impurities on the liquid surface to one side. The leaf spring gradually moves upward until it moves above the liquid surface, thereby realizing the automatic discharging of the leaf spring. At the same time, the air flow is used to ensure that the surface of the leaf spring is not adsorbed by impurities when discharging, effectively improving the cleanliness of the leaf spring and reducing the subsequent processing pressure.

[0028] (3) During the use of the fixed frame, the present invention also extracts and collects data on the identified features for accurate evaluation, combines the influence of the collected data itself and the influence on the quenching of the leaf spring, improves the pertinence of the control of the processing equipment, and can control the corresponding structure to perform compensatory operations according to the evaluation results, fundamentally reducing the influence caused by abnormalities and effectively improving the operating efficiency of the quenching processing equipment.

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1: Please refer to Figure 1 - Figure 4 As shown, this embodiment is a quenching treatment device for processing automotive leaf springs, including a fixing frame 1. A chamber one 11 and a chamber two 12 are provided in the fixing frame 1, and a guiding frame 13 and a quenching assembly 2 are fixedly installed in both the chamber one 11 and the chamber two 12;

[0040] The quenching assembly 2 includes a fixed pipe 21, a pump body 22 and a nozzle 23. The pump body 22 and the fixed pipe 21 are both fixedly installed on both sides of the fixed frame 1. The pump body 22 is fixedly connected to the fixed pipe 21 through a pipeline. A plurality of nozzles 23 are fixedly installed on one side of the fixed pipe 21, and the nozzles 23 are located on one side of the guiding frame 13;

[0041] A sliding frame 29 is movably installed on the side of the fixed frame 1 away from the airbag 24. A blanking plate 30 is movably installed in the sliding frame 29. A first lead screw 31 is movably installed on one side of the fixed frame 1. A first moving nut 32 is movably installed on the first lead screw 31 through a thread. The first moving nut 32 is fixedly connected to the sliding frame 29. One end of the blanking plate 30 is movably connected to the sliding frame 29 through a rotating shaft. A motor is fixedly installed on one side of the fixed frame 1, and the output end of the motor is fixedly connected to the first lead screw 31. That is, the first lead screw 31 is driven to rotate by the motor, and the first moving nut 32 is driven to move on the first lead screw 31 through the thread, thereby driving the sliding frame 29 to move.

[0042] An electric push rod 33 is fixedly installed in the sliding frame 29. The output end of the electric push rod 33 is movably connected to the blanking plate 30. Chute grooves are opened on both sides of the sliding frame 29. Sliding blocks are fixedly installed on both sides of the blanking plate 30, and the sliding blocks are movably installed in the chute grooves. After the leaf spring falls onto the blanking plate 30, the sliding frame 29 drives the leaf spring to move to a specified position. At this time, the electric push rod 33 is started to lift the bottom of the blanking plate 30. The blanking plate 30 starts to move with the rotating shaft as the fulcrum, and the sliding blocks slide in the chute grooves to ensure the stability of the blanking plate 30. As the blanking plate 30 gradually inclines, the leaf spring falls into the quenching liquid under the action of gravity.

[0043] During the quenching process of the leaf spring, neither loading nor unloading requires manual participation, which greatly improves the safety and stability of the quenching work.

[0044] A second lead screw 34 is movably installed in the fixed frame 1. A second moving nut 35 is movably installed on the second lead screw 34 through a thread. The second moving nut 35 is fixedly connected to the moving frame 25. A first synchronous pulley 36 is fixedly installed at the bottom of the second lead screw 34. That is, when the second lead screw 34 rotates, the third lead screw 37 is driven to rotate synchronously by the linkage cooperation of the first synchronous pulley 36 and the second synchronous pulley 38.

[0045] That is, first, quenching liquid is conveyed into the fixed frame 1, and the liquid level is flush with the top end of the guiding frame 13. At this time, the leaf spring to be quenched is conveyed onto the guiding frame 13. Under the action of gravity, the leaf spring slides on the guiding frame 13, and the leaf spring is quenched by the quenching liquid during the sliding process. At the same time, the pump body 22 is started to extract the quenching liquid at the bottom of the first cavity 11 or the second cavity 12 into the fixed pipe 21 and spray it out through the nozzles 23;

[0046] On the one hand, the bottom quenching liquid is lifted to avoid uneven temperature in cavity 11 or cavity 2 12. On the other hand, an axial water flow is formed through the nozzle 23 to form turbulence on the leaf spring, thereby increasing the contact time between the liquid and the leaf spring and effectively improving the quenching efficiency.

[0047] Example 2: Please refer to Figure 5 - Figure 6 As shown, the present invention also includes an airbag 24, a movable frame 25 and an air guide box 26. A through slot 27 is opened on the fixed frame 1, and the air guide box 26 is fixedly installed at the through slot 27. The movable frame 25 is movably installed in the fixed frame 1. The movable frame 25 is located at one end of the guide frame 13. The airbag 24 is fixedly installed on one side of the fixed frame 1. The airbag 24 is fixedly connected to the air guide box 26 through a pipeline. A movable plate 28 is movably installed on one side of the fixed frame 1, and the movable plate 28 is fixedly connected to the airbag 24.

[0048] A slide 29 is movably installed on the side of the fixed frame 1 away from the airbag 24, and a blanking plate 30 is movably installed in the slide 29. A screw rod 3 37 is movably installed on the end of the fixed frame 1 away from the screw rod 2 34. A synchronous wheel 2 38 is fixedly installed at the bottom of the screw rod 37. The synchronous wheel 1 36 is connected to the synchronous wheel 2 38 through a synchronous belt. A movable nut 39 is movably installed on the screw rod 3 37 through a thread. The movable nut 39 is fixedly connected to the movable plate 28. When the screw rod 2 34 rotates, the screw rod 3 37 rotates synchronously, thereby driving the movable nut 39 to move on the screw rod 3 37, and at the same time driving the movable plate 28 to periodically squeeze the airbag 24.

[0049] That is, after the quenching of the leaf spring is completed, the movable frame 25 is used to drive the leaf spring to move upward. During the upward movement, the movable plate 28 squeezes the airbag 24, and the gas enters the air guide box 26 and is blown to the liquid surface through the air guide box 26. The high-speed airflow is used to push the impurities on the liquid surface to one side, and the leaf spring gradually moves upward until it moves above the liquid surface, thereby realizing automatic discharging of the leaf spring. At the same time, the airflow is used to ensure that the surface of the leaf spring is not adsorbed by impurities when it is discharged, thereby effectively improving the cleanliness of the leaf spring and reducing the subsequent processing pressure.

[0050] Example 3: Please refer to Figure 7 As shown, the present invention further includes a control panel 3, and a control panel 3 is fixedly mounted on one side of the fixing frame 1. The control panel 3 includes a server, a temperature monitoring module, an impurity monitoring module and a remote monitoring terminal;

[0051] The temperature monitoring module monitors the quenching environment in the cavity 11 and the cavity 2 12, generates a normal temperature signal or an abnormal temperature signal through process analysis, and sends the abnormal temperature signal to the remote monitoring terminal through the server;

[0052] The specific operation process of the temperature monitoring module includes:

[0053] The quenching liquid temperature data of the first cavity 11 and the second cavity 12 are collected respectively, and the average value of all the quenching liquid temperature data within a unit time is calculated to obtain the temperature detection value. If the temperature detection value is greater than the preset temperature detection threshold, a temperature anomaly signal is generated.

[0054] The temperature detection value is obtained by the temperature collector fixedly installed in the fixing frame 1. The temperature detection value represents the temperature data of the quenching liquid inside the first cavity 11 and the second cavity 12. The higher its value, the higher the temperature of the quenching liquid. Taking three minutes as the time threshold, the temperature data of the quenching liquid inside the first cavity 11 and the second cavity 12 are collected, and the collected temperature data are averaged to obtain the temperature detection value. The obtained temperature detection value is compared with the preset temperature detection threshold. If the temperature detection value within this time threshold is greater than the preset temperature detection threshold, a temperature anomaly signal is generated and sent to the remote supervision terminal through the server.

[0055] The impurity monitoring module monitors the impurity concentration of the quenching liquid in the first cavity 11 and the second cavity 12, generates a deviation value through process analysis, compares and processes the deviation value to generate an impurity qualified signal or an impurity anomaly signal, and sends the impurity anomaly signal to the remote supervision terminal through the server;

[0056] The specific operation process of the impurity monitoring module includes:

[0057] The impurity data of the quenching liquid inside the first cavity 11 and the second cavity 12 are collected. The impurity data of the quenching liquid are obtained by the impurity concentration sensor fixedly installed in the fixing frame 1, that is, the average value of all the impurity concentration data within a unit time is calculated to obtain the impurity concentration value. Taking time as the X-axis and the collected impurity concentration value data as the Y-axis, a coordinate system is constructed, and the impurity concentration data within a unit time are marked on the coordinate system, and the threshold set for the corresponding data type is plotted on the coordinate system;

[0058] If the impurity concentration data fluctuates, it will show an upward trend on the coordinate system, that is, the area of the floating waveform deviation region between the impurity concentration data curve and the threshold curve is calculated. The area of the floating waveform deviation region within a unit time is the deviation value;

[0059] If the deviation value exceeds the set threshold and continues to increase, it is inferred that there is an abnormality in the quenching liquid in the current corresponding cavity, then an impurity anomaly signal is generated and sent to the remote supervision terminal through the server.

[0060] When the remote supervision terminal receives the temperature anomaly signal or the impurity anomaly signal, it immediately controls the carriage 29 to work and issues a corresponding warning.

[0061] Among them, the working principle of the carriage 29 is:

[0062] When the temperature or impurities in the first cavity 11 are abnormal, start the motor to drive the first lead screw 31 to rotate, use the carriage 29 to drive the leaf spring to move to the second cavity 12, quench the leaf spring through the quenching liquid in the second cavity 12, and give an early warning at the same time to remind the staff to check the inside of the first cavity 11. Similarly, if the temperature or impurities in the second cavity 12 are abnormal, drive the leaf spring to move to the first cavity 11 through the carriage 29, quench the leaf spring through the first cavity 11, and give an early warning, so as to ensure that the quenching of the leaf spring is in the best state each time and improve the product quality.

[0063] That is, during the use of the fixing frame 1, the extracted and identified features are used to collect data for accurate evaluation of the impact. Combining the impact of the collected data itself and the impact on the quenching of the leaf spring, the pertinence of the processing equipment control is improved, and according to the evaluation result, the corresponding structure can be controlled to perform compensatory operations, fundamentally reducing the impact caused by abnormalities and effectively improving the operating efficiency of the quenching processing equipment.

[0064] Combining Example 1, Example 2 and Example 3, it can be seen that not only can the data in the fixing frame 1 be collected to obtain a normal temperature signal and a qualified impurity signal, but also the attributes of the quenching liquid in the first cavity 11 and the second cavity 12 can be comprehensively and efficiently supervised during use, that is, the collected data range and the preset data range are comprehensively analyzed and compared, so as to obtain relevant evaluation signals, and accordingly give corresponding early warnings to the remote supervision terminal, realize the accurate judgment and control of the quenching timing, and for quenching abnormalities, through the cooperation of the first lead screw 31 and the carriage 29, replace the quenching pool, effectively improve the quenching effect of the leaf spring, and through the cooperation of the airbag 24 and the air guide box 26, realize the automatic cleaning of the impurities in the quenching liquid, effectively improve the quality of the finished leaf spring.

[0065] The above content is only an example and description of the structure of the present invention. Those skilled in the art of this technology can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined by this claim book, they should all fall within the protection scope of the present invention.
