Description

Technical Field

[0001] This utility model relates to the field of normalizing furnace discharge technology, and in particular to a rapid discharge device for a normalizing furnace. Background Technology

[0002] A normalizing furnace is an industrial heating device used for the normalizing treatment of metallic materials. Its main function is to improve the microstructure of metals and enhance their mechanical properties by controlling the heating and cooling process. Normalizing typically involves heating the metal workpiece above its critical temperature, holding it for a certain time, and then allowing it to cool naturally in air. This process refines the grains, homogenizes the microstructure, reduces internal stress, and improves toughness and machinability. Normalizing furnaces can use gas, oil, or electric heating methods and are commonly used for the heat treatment of steel, castings, and welded structures. They are widely used in industries such as machinery manufacturing, automotive, and aerospace to improve workpiece quality and production efficiency.

[0003] Currently, existing normalizing furnaces use trolleys to transfer metal workpieces. While this method offers high flexibility, the docking between the trolley and the normalizing furnace is often inaccurate during transfer or loading / unloading, leading to deviations. This can cause the trolley to fail to stop accurately at the designated position, resulting in inaccurate workpiece positioning and affecting subsequent processing precision. Furthermore, a gap exists between the docked trolley and the normalizing furnace, causing heat loss and uneven temperature distribution within the furnace. This negatively impacts the normalizing quality and performance of the workpieces and may also pose a safety hazard to operators. Therefore, there are certain safety risks associated with its use.

[0004] Based on this, we propose a rapid discharge device for normalizing furnaces to solve the aforementioned problems. Utility Model Content

The material transfer cart 4 includes a transfer tray 6, and a material placement component 7 is provided on the top of the transfer tray 6. This normalizing furnace discharge device, through the coordinated use of the material conveying platform 3, the material transfer cart 4, and the material discharge platform 5, facilitates the transfer and loading / unloading of metal workpieces to be processed. At the same time, it can also improve the accuracy of docking between the material transfer car 4 and the normalizing furnace body 1. An electric heater 8 is installed on the top of the normalizing furnace body 1, and a feed inlet 9 is opened at one end of the normalizing furnace body 1. An embedded baffle groove 10 is also opened on the outer side of the normalizing furnace body 1 near the feed inlet 9. By adding the electric heater 8 to the top of the normalizing furnace body 1, the electric heater 8 can provide the necessary normalizing heat source for the inside of the normalizing furnace body 1. When the electric heater 8 is powered on, it can raise the temperature inside the normalizing furnace body 1 to the required normalizing temperature, ensuring that the metal workpiece can be fully heated, so as to improve the microstructure and enhance the mechanical properties.

[0027] A first guide groove 11 is provided at the top center of the material transfer platform 3. An adjusting screw 12 is rotatably connected inside the first guide groove 11. Gear grooves 13 are provided on both sides of the top of the material transfer platform 3 near the first guide groove 11. A limit baffle 14 is installed at one end of the material transfer platform 3. A forward and reverse motor 15 is provided at the end of the material transfer platform 3 near the limit baffle 14. The output end of the forward and reverse motor 15 is connected to the adjusting screw 12. Second guide grooves 16 are also provided on both sides of the material transfer platform 3. By providing the first guide groove 11, gear groove 13, and second guide groove 16 on the material transfer platform 3, the stability and accuracy of the docking and movement of the transfer cart 6 can be improved, ensuring the smooth operation of the material transfer cart 4 during the feeding and discharging process. The transfer cart 6 is connected to the top of the two sets of material discharge platforms 5 by two sets of discharge guide rails 17. A sealing baffle 18 is installed at one end, and the sealing baffle 18 is structurally matched with the embedded baffle groove 10. The sealing baffle 18 and the embedded baffle groove 10 are in transition fit. The bottom sides of the transfer cart 6 and the sealing baffle 18 are provided with first guide plates 19. The first guide plates 19 and the second guide grooves 16 are structurally matched, and the first guide plates 19 and the second guide grooves 16 are in sliding fit. One side of each of the two sets of first guide plates 19 is rotatably connected to multiple sets of transmission gears 20. The transmission gears 20 are structurally matched with the gear grooves 13, and the transmission gears 20 and the gear grooves 13 are in meshing connection. Through the structural design of the transition fit between the sealing baffle 18 and the embedded baffle groove 10, gaps can be prevented when the normalizing furnace body 1 and the material transfer cart 4 are docked, which can improve the stability and airtightness of the docking between the material transfer cart 4 and the normalizing furnace body 1, and can effectively reduce heat loss.

[0028] Both the transfer tray 6 and the sealing baffle 18 have a second guide plate 21 at their bottom center. The second guide plate 21 matches the structure of the first guide groove 11. An adjusting screw hole 22 is opened in the center of the second guide plate 21. The adjusting screw hole 22 and the adjusting screw 12 are threaded together. Through the threaded connection between the adjusting screw hole 22 and the adjusting screw 12, when the forward and reverse motors 15 drive the adjusting screw 12 to rotate, the thread action between the adjusting screw 12 and the adjusting screw hole 22 can convert the rotational motion into linear motion. This allows for precise control of the position of the transfer tray 6 on the material transfer table 3. This threaded connection method has high transmission accuracy and can realize the precise control of the transfer tray 6. Fine-tuning ensures precise alignment with the normalizing furnace body 1, improving production efficiency and automation. The material placement component 7 includes a heat insulation pad 23, and two sets of discharge chutes 24 are provided at the bottom of the heat insulation pad 23. The discharge chutes 24 are structurally matched with the discharge guide rail 17, and the discharge chutes 24 and the discharge guide rail 17 are in sliding fit. Through the structural design of the sliding fit between the discharge chutes 24 and the discharge guide rail 17, when the transfer cart 6 drives the material placement component 7 to move on the top of the material transfer platform 3 equipped with the limit baffle 14, the equipment can quickly transfer the material placement component 7 with metal workpieces on top to the material discharge platform 5 according to the usage situation, so as to realize the rapid discharge of metal workpieces.

[0029] Working Principle: The normalizing furnace discharge device designed in this scheme mainly consists of a material conveying platform 3, a material transfer cart 4, and a material discharge platform 5. The material transfer cart 4 includes a transfer cart disc 6 and a material placement component 7. The transfer cart disc 6, with the material placement component 7 mounted on top, is connected to the top of the material conveying platform 3 through the cooperation of a first guide groove 11, an adjusting screw 12, a gear groove 13, a forward and reverse motor 15, a second guide groove 16, a first guide plate 19, a transmission gear 20, a second guide plate 21, and an adjusting screw hole 22. When the forward and reverse motor 15 is powered on, the transfer cart disc 6 can drive the material placement component 7 to move horizontally on the top of the material conveying platform 3, facilitating the transfer and feeding / unloading of the metal workpieces to be processed in the normalizing furnace body 1. At the same time, it can also improve the accuracy of the docking between the material transfer cart 4 and the normalizing furnace body 1, effectively eliminating the positional deviation of the metal workpieces caused by mechanical deviation, thereby ensuring the uniform heating of the metal workpieces during the heat treatment process, improving the normalizing quality and subsequent processing accuracy.

[0030] The normalizing furnace discharge device designed in this scheme, when the material transfer cart 4 with metal workpieces on top docks with the normalizing furnace body 1, uses an embedded baffle 10 on the outside of the normalizing furnace body 1 and a sealing baffle 18 installed at one end of the transfer cart plate 6. Because the sealing baffle 18 and the embedded baffle 10 are structurally matched and have a transition fit, gaps can be prevented when the normalizing furnace body 1 and the material transfer cart 4 dock. This improves the stability and airtightness of the docking between the material transfer cart 4 and the normalizing furnace body 1, effectively reduces heat loss, and keeps the temperature inside the normalizing furnace body 1 in a more stable state, thereby saving energy and improving product quality. In addition, this device also enhances the safety of the production process, avoiding equipment failures and safety hazards to operators that may be caused by docking errors between the material transfer cart 4 and the normalizing furnace body 1.
