Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold steel processing technology, specifically a heat treatment component for mold steel processing. Background Technology
[0002] Mold steel is a special alloy steel used to manufacture molds. Due to its good hardness, wear resistance, toughness and other properties, it is widely used in the manufacture of various molds. In the processing of mold steel, heat treatment is a crucial step. The effect of the heat treatment directly affects the hardness, wear resistance, toughness and other properties of the mold steel, and thus affects the service life of the mold and the quality of the product.
[0003] Traditional heat treatment components for mold steel processing still use conventional heating methods, which may lead to localized overheating or insufficient heating of the mold steel during the heating process. This affects the microstructure transformation and performance improvement of the mold steel. Furthermore, if the different cooling rate requirements of different mold steel materials cannot be met, it can easily cause problems such as cracking or uneven hardness of the mold steel. Therefore, there is a need for a heat treatment component for mold steel processing that adopts a new heating method and can cool as needed. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1:
[0021] Referring to Figures 1-3, a heat treatment assembly for mold steel processing includes a base 1, a heat treatment shell 2 fixedly connected to the top of the base 1, a servo motor 3 fixedly installed inside the base 1, a drive rod 4 fixedly connected to the output end of the servo motor 3, a placement platform 5 fixedly connected to the outer surface of the drive rod 4, a connecting rod 6 fixedly connected to the bottom of the placement platform 5, an annular groove 8 opened inside the heat treatment shell 2, a slider 7 slidably engaged inside the annular groove 8, the top of the slider 7 fixedly connected to the bottom of the connecting rod 6, a microwave generator 9 fixedly installed inside the heat treatment shell 2, a heating shell 10 fixedly connected inside the heat treatment shell 2, a resistance heating element 11 disposed inside the heating shell 10, a fixing block 19 fixedly connected inside the heat treatment shell 2, the interior of the fixing block 19 movably connected to the outer surface of the drive rod 4, and a controller 20 fixedly installed on the outer surface of the heat treatment shell 2.
[0022] Working principle: First, use the handle 15 to open the movable door panel 14, place the mold steel to be heat-treated on the placement platform 5, start the servo motor 3 through the controller 20, and let the drive rod 4 drive the placement platform 5 and the mold steel to rotate at a uniform speed. Then, start the microwave generator 9 and the resistance heating element 11 through the controller 20 respectively. In the low temperature stage (<600℃): microwave and resistance heating are started at the same time for rapid heating. In the high temperature stage (>600℃): microwave is turned off and only resistance heating is used to maintain the temperature to avoid the reflection loss of microwave by metal. Combining the rapid heating capability of microwave and the stability of resistance heating, the entire mold steel is heated more evenly, which is suitable for molds with extremely high requirements for temperature uniformity. When the placement platform 5 rotates, its bottom is connected by the connecting rod 6 to let the slider 7 slide in the annular groove 8, which plays an auxiliary support role. The fixed block 19 plays the role of supporting the drive rod 4.
[0023] Example 2:
[0024] Please refer to Figures 1-4. The heat treatment shell 2 is fixedly connected to the internal chassis 12. The internal chassis 12 is fixedly installed with a cooling fan 13. The front surface of the heat treatment shell 2 is movably connected to a movable door panel 14. The outer surface of the movable door panel 14 is fixedly installed with a handle 15. The interior of the movable door panel 14 and the interior of the heat treatment shell 2 are both movably connected to a movable mounting plate 16. The outer surface of the movable mounting plate 16 is fixedly installed with a pull block 17. The interior of the movable door panel 14 and the interior of the heat treatment shell 2 are both fixedly connected to a heat dissipation mesh plate 18.
[0025] Working principle: After heating, the cooling method can be selected according to the needs. Furnace cooling means that the mold steel is slowly cooled to room temperature or a certain predetermined temperature after heating and holding. The cooling rate is extremely slow, the internal temperature difference of the workpiece is small, the stress is low, the microstructure transformation is sufficient, and it is easy to obtain an equilibrium microstructure. It is used for annealing process to eliminate stress, soften the material or homogenize the microstructure, and avoid cracking or deformation. Air cooling means that the movable mounting plates 16 at the front and rear are opened by using the pull block 17 respectively, and the mold steel is placed in the air for natural cooling through the heat dissipation mesh plate 18. Forced air cooling means that the cooling fan 13 is started by the controller 20 to accelerate the air flow to meet the cooling needs of different mold steel materials.
