Description

Technical Field

[0001] The utility model relates to the field of material racks, in particular to an improved casting material rack. Background Art

[0002] Workpiece heat treatment is a crucial industrial process that significantly improves the physical and chemical properties of materials through precisely controlled heating, holding, and cooling cycles. This technique is widely used on metal and alloy workpieces to enhance their hardness, strength, toughness, wear resistance, and corrosion resistance to meet the stringent requirements of specific applications. The heat treatment process typically begins by placing the workpiece in a heating device. A variety of equipment types, such as resistance furnaces, induction heaters, and gas furnaces, are available, depending on the workpiece material and the scale of the treatment being performed. During the heating phase, the workpiece is uniformly heated to a predetermined temperature, determined by the material's phase transition point and the desired property changes. After reaching the predetermined temperature, the workpiece is held in the furnace for a period of time, known as the holding phase. This phase allows for necessary adjustments in the material's internal structure and composition, such as grain growth, phase transformation, and element diffusion, to occur, thereby optimizing the material's overall properties. After the holding phase, the workpiece is cooled rapidly or slowly through a specific cooling method. The cooling rate has a decisive influence on the final properties. For example, quenching rapidly increases hardness, while annealing helps relieve stress and improves toughness. To improve the efficiency and quality of heat treatment and ensure consistent and stable performance, the workpiece is often placed on a rack for heat treatment. However, when the workpiece is placed in the rack for heat treatment, it is affected by external forces and is prone to shaking in the rack. The shaking workpiece is prone to collide with the rack, and the workpiece is prone to damage after colliding with the rack. Therefore, an improved casting rack is needed to solve the above problems.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, an improved casting material rack includes a material rack body 1, and a plurality of limit assemblies 2 are installed in the material rack body 1. The limit assembly 2 consists of a mounting base 6, a limit guide rod 8 and a fixed spring 9. The limit guide rod 8 and the fixed spring 9 are both mounted on the upper end of the mounting base 6, and there are two limit guide rods 8 and they are respectively located on both sides of the fixed spring 9. A fixed assembly 3 is installed on the three longitudinal limit assemblies 2. The fixed assembly 3 consists of a fixed pressure plate 10, a disassembly handle 11 and a trapezoidal card strip 12. There are two disassembly handles 11 and they are respectively mounted at both ends of the fixed pressure plate 10. The trapezoidal card strip 12 is mounted on the upper end of the fixed pressure plate 10. A material rack body 1 is stacked on the positioning disk 4, and a plurality of mounting slots 5 are provided on the material rack body 1. Two through holes are symmetrically provided on the top wall of the mounting slot 5. Before heat treatment of the workpiece, in order to ensure the efficiency and quality of heat treatment of the workpiece, and to ensure the stability and consistency of the performance of the workpiece, the workpiece can be placed in the material rack body 1 for heat treatment. The method of placing the workpiece in the material rack body 1 is to simply insert the workpiece into the card slot provided in the material rack body 1, and then use the limit assembly 2 and the fixing assembly 3 to fix the placed workpiece, and finally stack the material rack body 1 containing the workpiece on the positioning disk 4 for heat treatment.

[0020] Finally, by setting a limit component 2 and a fixing component 3 on the rack body 1 and making them cooperate with each other, the workpiece placed in the rack body 1 can be fixed, thereby reducing the probability of the workpiece placed in the rack body 1 shaking, and then reducing the probability of the workpiece colliding with the rack body 1, and finally reducing the probability of damage to the workpiece during the heat treatment process, ensuring that the produced workpiece has good quality.

[0021] Furthermore, the mounting base plate 6 on the limit assembly 2 is slidably mounted in the mounting groove 5 opened on the material rack body 1, and a trapezoidal slot 7 is opened at the lower end of the mounting base plate 6. The limiting guide rod 8 on the limit assembly 2 is slidably mounted in the through hole opened on the top wall of the mounting groove 5, and the limiting guide rod 8 is fixedly connected to the mounting base plate 6, and the fixing spring 9 is fixedly connected to the top wall of the mounting groove 5. The fixing spring 9 is also fixedly connected to the upper end of the mounting base plate 6, and the fixing assembly 3 is inserted into the mounting groove 5 opened on the material rack body 1. The fixed pressure plate 10 is located at the lower end of the mounting base plate 6 on the limit assembly 2, and the trapezoidal card strip 12 is inserted into the trapezoidal card slot 7 opened at the lower end of the mounting base plate 6. The fixed pressure plate 10 is fixedly connected to the disassembly handle 11 and the trapezoidal card strip 12. When the workpiece is inserted into the material rack body 1, the fixing assembly 3 can be inserted into the limit assembly 2. The method is as follows: first push the mounting base plate 6 on the limit assembly 2 upward. At this time, the limiting guide rod 8 will move upward in the through hole opened on the top wall of the mounting groove 5, and the mounting base plate 6 will move in the mounting groove 5. When the workpiece is moved upward, the fixing spring 9 will be compressed by the fixing base 6 as the fixing base 6 moves upward. When the lower end of the fixing base 6 is higher than the workpiece, the trapezoidal card strip 12 on the fixing component 3 is inserted into the trapezoidal card slot 7 opened at the lower end of the fixing base 6. When the fixing component 3 is inserted into the three limit components 2, the limit component 2 and the fixing component 3 are released. At this time, under the elastic force of the fixing spring 9, the limit guide rod 8, the fixing base 6 and the fixing component 3 will move downward, so that the fixing component 3 moving downward will eventually Press on the workpiece, and then press the workpiece tightly and fix it; when the workpiece has completed heat treatment and needs to be taken out from the rack body 1, the fixing component 3 can be removed from the limiting component 2 first. During this process, the trapezoidal clip 12 on the fixing component 3 needs to be pulled out from the trapezoidal clip 7 opened at the lower end of the mounting base 6. When the trapezoidal clip 12 is completely removed from the trapezoidal clip 7, the fixing component 3 is removed from the limiting component 2. At this time, the fixation of the workpiece will be contacted, and then the workpiece can be taken out from the rack body 1.
