Description

Technical Field

[0001] This invention relates to heat treatment processes, and more specifically, to a control method and apparatus for achieving efficient annealing of engine blocks. Background Art

[0002] Annealing is an important heat treatment process in engine manufacturing and repair, primarily used to improve the internal structure of metallic materials, eliminate internal stress, and adjust mechanical properties. Annealing is an indispensable process in engine manufacturing, ensuring the machinability, dimensional stability, and service reliability of parts by controlling material microstructure and stress. Specific annealing parameters (temperature, time, cooling rate) need to be determined based on the material composition (e.g., cast iron, aluminum alloy, alloy steel) and process requirements. However, most existing annealing devices currently lack effective temperature detection and processing mechanisms, resulting in inaccurate temperature control, low cooling rates, and difficulty in meeting the annealing requirements of current engine blocks, leading to low work efficiency.

[0012] A method for using the aforementioned control device for achieving efficient annealing of an engine block, the method comprising:

[0013] Step 1: The engine block is sanded using a sand scraper, and the sanded engine block is transported to the entrance of the first heating platform by the first electric transport vehicle.

[0014] Step 2: Start the first and second conveyor belt structures, and move the scraped engine block from the first electric transport vehicle to the first heating platform through the loading structure;

[0015] Step 3: The engine block after sand scraping is subjected to preliminary heating treatment according to the preset heating treatment mechanism. The engine block after preliminary heating treatment is slowly moved to the end of the first heating platform through the first conveyor belt structure.

[0016] Step 4: The engine block, after preliminary heat treatment, is transferred from the first heating platform to the second heating platform via a transfer structure;

[0017] Step 5: Perform secondary heating treatment on the engine block through the second heating platform; perform slow cooling treatment on the engine block after secondary heating treatment according to the preset slow cooling treatment mechanism; and perform strong cooling treatment on the engine block after slow cooling treatment according to the preset strong cooling treatment mechanism.

[0018] Step Six: Unload the engine block after the strong cooling treatment through the unloading structure.

[0019] As a further improvement, in step three, the heating mechanism is as follows: the real-time temperature of the first furnace body is obtained through the first temperature sensor; when the real-time temperature is lower than a preset heating temperature threshold, the difference between the real-time temperature of the first furnace body and the heating temperature threshold is obtained to obtain a heating temperature difference value; the heating temperature difference value is compared with a preset heating temperature difference standard value; when the heating temperature difference value is less than or equal to the heating temperature difference standard value, the power of the circulating fan is increased to a preset first fan power; when the heating temperature difference value is greater than the heating temperature difference standard value, the power of the electric heating radiant tube is increased to a preset first heating power.

[0020] Furthermore, in step five, the slow cooling mechanism is as follows:

[0021] The real-time temperature of the second furnace body is obtained by a second temperature sensor. When the real-time temperature of the second furnace body is higher than a preset first cooling temperature threshold, the difference between the real-time temperature of the second furnace body and the first cooling temperature threshold is used to obtain a cooling temperature difference value. The cooling temperature difference value is compared with a preset cooling temperature difference standard value. When the cooling temperature difference value is less than or equal to the cooling temperature difference standard value, the power of the air cooler is increased to a preset first fan power. When the cooling temperature difference value is greater than the cooling temperature difference standard value, the power of the air cooler is reduced to a preset second fan power.

[0022] Furthermore, in step five, the strong cooling mechanism involves obtaining the real-time temperature of the second furnace body through a second temperature sensor. When the real-time temperature of the second furnace body is higher than a preset second cooling temperature threshold, the difference between the real-time temperature of the second furnace body and the second cooling temperature threshold is used to obtain a cooling temperature difference value. This cooling temperature difference value is compared with a preset cooling temperature difference standard value. When the cooling temperature difference value is less than or equal to the cooling temperature difference standard value, the power of the air cooler is increased to a preset third fan power. When the cooling temperature difference value is greater than the cooling temperature difference standard value, the power of the air cooler is reduced to a preset first fan power.

[0040] A method for using the above-described control device for achieving efficient annealing of an engine block, the method comprising:

[0041] Step 1: The engine block is sanded by the sand scraper 1, and the sanded engine block is transported to the entrance of the first heating platform 2 by the first electric transport vehicle 9.

[0042] Step 2: Start the first conveyor belt structure 23 and the second conveyor belt structure 24, and move the scraped engine block from the first electric transport vehicle 9 to the first heating platform 2 through the loading structure;

[0043] Step 3: The engine block after sand scraping is subjected to preliminary heating treatment according to the preset heating treatment mechanism. The engine block after preliminary heating treatment is slowly moved to the end of the first heating platform 2 via the first conveyor belt structure 23.

[0044] In step three, the heating mechanism is as follows: the real-time temperature of the first furnace body is obtained through the first temperature sensor; when the real-time temperature is lower than the preset heating temperature threshold, the difference between the real-time temperature of the first furnace body and the heating temperature threshold is obtained to obtain the heating temperature difference value; the heating temperature difference value is compared with the preset heating temperature difference standard value; when the heating temperature difference value is less than or equal to the heating temperature difference standard value, the power of the circulating fan is increased to the preset first fan power; when the heating temperature difference value is greater than the heating temperature difference standard value, the power of the electric heating radiant tube is increased to the preset first heating power.

[0045] Step 4: The engine block, after preliminary heating treatment, is transferred from the first heating platform 2 to the second heating platform 3 via a transfer structure.

[0046] Step 5: Perform secondary heating treatment on the engine block through the second heating platform 3; perform slow cooling treatment on the engine block after secondary heating treatment according to the preset slow cooling treatment mechanism, and perform strong cooling treatment on the engine block after slow cooling treatment according to the preset strong cooling treatment mechanism.

[0047] In step five, the slow cooling mechanism is as follows:

[0048] The real-time temperature of the second furnace body is obtained by the second temperature sensor. When the real-time temperature of the second furnace body is higher than the preset first cooling temperature threshold, the difference between the real-time temperature of the second furnace body and the first cooling temperature threshold is obtained to obtain the cooling temperature difference value. The cooling temperature difference value is compared with the preset cooling temperature difference standard value. When the cooling temperature difference value is less than or equal to the cooling temperature difference standard value, the power of the air cooler is increased to the preset first fan power. When the cooling temperature difference value is greater than the cooling temperature difference standard value, the power of the air cooler is reduced to the preset second fan power.

[0049] In step five, the forced cooling mechanism involves acquiring the real-time temperature of the second furnace body using a second temperature sensor. When the real-time temperature of the second furnace body is higher than a preset second cooling temperature threshold, the difference between the real-time temperature and the second cooling temperature threshold is calculated to obtain a cooling temperature difference value. This cooling temperature difference value is compared with a preset standard cooling temperature difference value. If the cooling temperature difference value is less than or equal to the standard cooling temperature difference value, the power of the air cooler is increased to a preset third fan power. If the cooling temperature difference value is greater than the standard cooling temperature difference value, the power of the air cooler is reduced to a preset first fan power. Specifically, the rated fan power > third fan power > first fan power > second fan power. The second cooling temperature threshold < the first cooling temperature threshold.

[0050] Step Six: Unload the engine block after strong cooling treatment through the unloading structure.

[0051] Operating procedures: First, check that the equipment is intact and free from abnormalities (power supply voltage, hydraulic oil cooling water circulation, detection switches, all transmission mechanisms, motor protection circuit breakers, etc.). All transfer switches should be in the off position.

Click to connect the computer and the instrument (the zone names will be blue when connected and white when offline). Set the temperature and cycle time for each zone according to the process settings. After completion, return to the homepage and click to exit the parameter setting interface to prevent the process parameters from being modified.

[0055] Manually return each operating mechanism of the equipment to its original position. Check the original position interface; if all indicator lights are green, the original conditions are met, and the start indicator light will flash.

The hydraulic pump will start, and the hydraulic pump indicator light will illuminate after 10 seconds. Press the start button for 3 seconds, and the start indicator light will stop flashing and remain on. The automatic indicator light will remain on, indicating that the system has entered automatic operation mode.

[0057] Instructions and Precautions

[0058] 1. Three-color warning light: Red indicates a temperature fault, which will illuminate when a certain area is overheated or the hydraulic oil temperature is too high or too low; Yellow indicates a motor fault, which will illuminate when the motor trips or the fan inverter alarms; Green indicates that the equipment is normal.

[0059] 2. This equipment is an automated production line. Do not manually interfere with the detection switch signals during automatic operation, otherwise the program will be disrupted, causing serious damage to the equipment and even personal injury.

[0061] 4. When shutting down the furnace, it is best to leave the equipment in its original position to avoid having to manually adjust it when starting it up again.

[0062] 5. The reset procedure is performed before each start-up and when automatic operation is stopped to prevent the motor or cylinder from malfunctioning and causing an accident.

[0063] 6. It is strictly forbidden to use other media (USB flash drives, hard drives, MP3 players, etc.) to copy or load files through the industrial control computer. It is also forbidden to install any other software unrelated to the device on the computer. The dongle is for KingSCADA software and cannot be used as a USB flash drive; it is a valuable item and should not be removed.

[0064] 7. After the heating is turned off, the furnace temperature should be reduced to below 250℃ before turning off the switches of each circulating fan.

The method for controlling efficient annealing of engine blocks according to claim 7, characterized in that, In step three, the heating mechanism is as follows: the real-time temperature of the first furnace body is obtained through the first temperature sensor; when the real-time temperature is lower than a preset heating temperature threshold, the difference between the real-time temperature of the first furnace body and the heating temperature threshold is obtained to obtain a heating temperature difference value; the heating temperature difference value is compared with a preset heating temperature difference standard value; when the heating temperature difference value is less than or equal to the heating temperature difference standard value, the power of the circulating fan is increased to a preset first fan power; when the heating temperature difference value is greater than the heating temperature difference standard value, the power of the electric heating radiant tube is increased to a preset first heating power.

9. The method for controlling efficient annealing of engine blocks according to claim 7, characterized in that, In step five, the slow cooling mechanism is as follows: The real-time temperature of the second furnace body is obtained by a second temperature sensor. When the real-time temperature of the second furnace body is higher than a preset first cooling temperature threshold, the difference between the real-time temperature of the second furnace body and the first cooling temperature threshold is used to obtain a cooling temperature difference value. The cooling temperature difference value is compared with a preset cooling temperature difference standard value. When the cooling temperature difference value is less than or equal to the cooling temperature difference standard value, the power of the air cooler is increased to a preset first fan power. When the cooling temperature difference value is greater than the cooling temperature difference standard value, the power of the air cooler is reduced to a preset second fan power.

10. The method for controlling efficient annealing of engine blocks according to claim 7, characterized in that, In step five, the forced cooling mechanism involves obtaining the real-time temperature of the second furnace body through a second temperature sensor. When the real-time temperature of the second furnace body is higher than a preset second cooling temperature threshold, the difference between the real-time temperature of the second furnace body and the second cooling temperature threshold is calculated to obtain a cooling temperature difference value. This cooling temperature difference value is then compared with a preset cooling temperature difference standard value. When the cooling temperature difference value is less than or equal to the cooling temperature difference standard value, the power of the air cooler is increased to a preset third fan power. When the cooling temperature difference value is greater than the cooling temperature difference standard value, the power of the air cooler is reduced to a preset first fan power.
