Abstract
Description
Technical Field
[0001] This utility model belongs to the field of aerospace heat treatment technology, specifically relating to a tooling for preventing deformation during heat treatment of parts. Background Technology
[0002] The characteristics of aerospace heat treatment include complex part structures, high precision requirements, small batch sizes, and non-mass production. Therefore, heat treatment production must ensure both part quality and furnace loading capacity, while maintaining economic efficiency as much as possible. During part production, parts are constantly subjected to downward gravity, making them prone to deformation during heat treatment. Furthermore, improper placement can lead to uneven coolant distribution on the part surface, resulting in insufficient cooling and affecting the heat treatment effect and the part's mechanical properties. Therefore, most parts need to be placed vertically during heat treatment, requiring the design of tooling suitable for the vertical placement of various part types. Utility Model Content
[0003] The purpose of this invention is to provide a detachable, multi-purpose quenching rack that allows parts to be placed vertically, solving the problem of easy deformation during heat treatment of various types of parts and minimizing the amount of deformation.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a detachable multi-purpose quenching material rack, including a partition plate, on which a perforated plate is placed. The diameter of the through hole A on the perforated plate is smaller than the diameter of the through hole B on the partition plate, and the through holes A and B are connected vertically for vertical insertion of parts; there are multiple through holes A and B.
[0005] Preferably, the perforated plate is composed of multiple perforated plate units, and the outer circumference of the assembled plate is placed on the outer circumference of the partition plate.
[0006] Preferably, the perforated plate unit is fan-shaped, and its center after assembly is coaxial with the center of the partition plate.
[0007] Preferably, the outer circumference of the perforated plate is provided with a U-shaped notch that mates with the partition and a through hole for the support column to pass through.
[0008] Preferably, the partition plate and the perforated plate are made of stainless steel material 1Cr18Ni9Ti.
[0009] Preferably, adjacent upper and lower partitions are supported and separated by sleeves fitted onto the support column.
[0010] Preferably, the outer circumference of the partition plate is higher than its upper and lower surfaces.
[0011] Compared with the prior art, the present invention has the following advantages:
[0012] 1. It enables parts to be placed vertically, solving the problem of easy deformation of existing parts during heat treatment and minimizing the amount of deformation as much as possible;
[0013] 2. Increased furnace loading capacity, simplified operation, reduced confusion between parts of different drawing numbers, and the ability to select appropriate tooling based on part size and type, resulting in a significant improvement in heat treatment production efficiency and part quality.
[0014] 3. The tooling has a simple structure, long service life, and strong load-bearing capacity. Attached Figure Description

[0021] The following is in conjunction with the appendix Figure 1-5 The present invention is further described in detail as follows: A detachable multi-purpose quenching material rack includes a partition plate 1, on which a perforated plate 5 is placed. The diameter of the perforated plate through hole 6 on the perforated plate 5 is smaller than the diameter of the circular hole 2 and the square hole 3 on the partition plate. The perforated plate through hole 6, the circular hole 2 and the square hole 3 on the partition plate are connected vertically for vertical insertion of parts. There are multiple perforated plate through holes 6, circular holes 2 and square holes 3 on the partition plate.
[0022] Choose one of two loading schemes based on the size and type of the parts:
[0023] 1. If the part is large and the diameter of the through hole in the partition is large, it can be directly inserted into the partition. Partition 1 has a circular hole 2 and a square hole 3. The circular hole 2 is slightly smaller, and the square hole 3 is slightly larger. Choose the appropriate placement position according to the size of the part; for example, if the heat-treated part is large, it can be directly inserted into the smaller circular hole 2 of the partition. Larger parts can be placed vertically in the larger square hole 3.
[0024] 2. If the parts are small, some may fall if placed directly in the partition plate 1. Even if they can be held in place, they are prone to shaking and deformation during heat treatment. Therefore, it is preferable to place the parts in the perforated plate 10. Figure 1 As shown, the perforated plate is placed in the material basket together with the partition plate, in the following state. Figure 2-3 The parts are placed in the perforated plate and partition plate as shown in Figure 11.
[0025] The size of the through hole 6 in the perforated plate is designed to be different according to the size of the part. The parts can be separated by the partition plate 1 and the perforated plate 5 to prevent the parts from moving, gathering and sticking together, and to prevent the thickness of the parts from increasing, so as to avoid the problem of incomplete quenching.
[0026] The partition plate 1 is circular. Based on its size, one partition plate 1 can hold four perforated plates 5. The perforated plates 5 are fan-shaped and perfectly match the partition plate 1, making efficient use of the tooling space, minimizing obstruction of the partition plate, avoiding wasted space, maximizing the loading of parts, increasing the furnace load, and improving production efficiency. The perforated plates have U-shaped notches 7 to match the shape of the partition plate. Protruding support rods 8 secure the fan-shaped perforated plates 5 at the center and around the perimeter, preventing them from falling off during heat treatment. The fan-shaped perforated plates 5 are freely detachable and can be freely combined in different sizes.
[0027] The partition plate 1 is connected to the support rod 8 by sleeve 9. The spacing height of the partition plate 1 can be adjusted by adding or removing sleeve 9 according to the type, size and quantity of the parts, so as to maximize the number of loading layers and increase the overall loading capacity under the same furnace loading space.
[0028] By employing two methods, parts of different sizes can be placed vertically, which can greatly reduce the deformation of the parts, increase the loading capacity, and effectively improve the production efficiency of heat treatment.
[0029] Meanwhile, for situations where quenching can be done in the same furnace but tempering cannot, parts that can be tempered in the same furnace can be placed in the same layer or the same perforated plate. When tempering, the perforated plate 5 can be directly removed, and the parts follow the perforated plate, making them easy to remove. Parts with different drawing numbers are also less likely to be confused, saving time and effort and ensuring quality.
[0030] The partition plate 1 and the fan-shaped perforated plate 5 are made of stainless steel material 1Cr18Ni9Ti to ensure the load-bearing strength, deformation resistance and corrosion resistance of the tooling, and to increase the service life of the tooling.
