Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat treatment equipment, in particular to a heat treatment rack. BACKGROUND

[0002] Solution heat treatment is a common method of processing metal materials, which aims to change the crystal structure and properties of the material through the process of heating and cooling, in order to improve the strength, hardness, corrosion resistance and other purposes of the material. Specifically, it refers to heating the alloy to the single-phase solid solution phase region, maintaining at a suitable temperature for a suitable time, and then rapidly cooling to room temperature to obtain a supersaturated solid solution. Based on the formation and precipitation of solid solution, the properties of the material are changed by controlling the formation and precipitation process of the solid solution.

[0003] Some target material back plates need to be heat treated to improve hardness, and the key step is solution heat treatment. In order to ensure the uniformity of the performance of each part of the large-size back plate, it should be ensured that each part enters the cooling medium at the same time during rapid cooling. The target material back plate is usually in the form of a round cake, and its diameter is much larger than its thickness, so the most optimal choice is to place the end face of the target material back plate horizontally in the medium for cooling. However, in order to ensure that each part of the back plate is uniformly heated and warmed up during heat treatment, the back plate is usually placed vertically on the end face in the heat treatment furnace, so it is necessary to make the back plate enter the cooling medium horizontally after being taken out of the furnace, so as to maximize the instantaneous cooling volume of the product and ensure the uniformity of the performance of each part of the product.

[0004] Therefore, it is urgent to provide a heat treatment rack to realize the turnover of the product back plate. SUMMARY

[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] In this embodiment, product 100 is a solution-treated heat-treated part with a plate-like structure such as a target back plate. During heat treatment, product 100, such as... Figure 1 As shown, to ensure uniform heating of all parts of the back panel, the machined surface 110 of product 100 needs to be placed vertically in the heat treatment furnace 200, thus avoiding the problem of insufficient air convection around the middle back panel when placed horizontally; and to ensure the uniformity of performance of all parts of the large-size back panel, rapid cooling should ensure that all parts enter the cooling medium 300 simultaneously as much as possible, such as... Figure 2 As shown, placing the machined surface 110 of product 100 horizontally into the cooling medium 300 for cooling is the optimal choice. For this purpose, a flipping mechanism is needed to realize the conversion of product 100 from a vertical state to a horizontal state.

[0033] like Figures 3-5As shown, the heat treatment rack provided in this embodiment includes a flipping mechanism, which includes two clamping parts 2 and two rotating parts 1. The two clamping parts 2 are arranged opposite to each other and are used to clamp the opposite side edges of the product 100. The product 100 includes a processed surface 110. Each rotating part 1 is rotatably connected to a corresponding clamping part 2. The two rotating parts 1 rotate in the same direction, and the axes of rotation of the two rotating parts 1 are parallel to the processed surface 110. The rotation angle is greater than or equal to 90°. The rotating part 1 is located on the side of the clamping part 2 away from the product 100. With this heat treatment rack design, during the heat treatment of the product 100, the clamping part 2 holding the product 100 can be flipped 90° by operating the two rotating parts 1, thereby flipping the product 100 from a vertical state to a horizontal state. This allows the processed surface 110 of the product 100 to enter the cooling medium 300 in a horizontal state, maximizing the instantaneous cooling volume of the product 100 and ensuring the uniformity of the performance of each part of the product 100.

[0034] Furthermore, such as Figure 4 As shown, the clamping part 2 is provided with a through groove, the axis of which is parallel to the machining surface 110. The product 100 is detachably inserted into the through grooves on the two clamping parts 2. The two through grooves firmly clamp the product 100, facilitating subsequent heat treatment.

[0035] Preferably, the through groove is a U-shaped groove. Using two U-shaped grooves to hold the product 100 in place reduces the risk of damaging the board material.

[0036] Furthermore, such as Figure 3 and Figure 5 As shown, the heat treatment rack also includes two opposing push-pull members 11. One end of the rotating member 1 is rotatably connected to the side of the clamping part 2 away from the product 100, and the other end is fixedly connected to the push-pull member 11. The angle between the rotating member 1 and the push-pull member 11 is a right angle. When it is necessary to flip the product 100, the two push-pull members 11 can be pushed or pulled. The push-pull members 11 make the flipping action of the product 100 convenient and labor-saving.

[0037] Preferably, the two push-pull members 11 extend in opposite directions to facilitate the push-pull operation of the two push-pull members 11.

[0038] Furthermore, the push-pull component 11 can be connected to drive components such as motors or cylinders to achieve automated production.

[0039] Preferably, there are at least two flipping mechanisms. For example, the number of flipping mechanisms can be two, three, or four, etc. The rotating part 1 of each flipping mechanism is fixedly connected to the push-pull part 11, and the included angle between the rotating part 1 and the push-pull part 11 of each flipping mechanism is a right angle. The arrangement of multiple flipping mechanisms enables the heat-treated parts to be mass-produced.

[0040] Preferably, such as Figure 3 As shown, at least two flipping mechanisms are evenly distributed horizontally. During cooling, products in the same furnace should enter the cooling medium simultaneously to ensure the consistency of performance within the same batch. Different cooling times will inevitably lead to differences in product performance. Therefore, the horizontal distribution of at least two flipping mechanisms ensures that at least two clamped products enter the cooling medium simultaneously, with consistent cooling times. The even distribution of at least two flipping mechanisms also ensures uniform air convection and consistent heating rates between each product in the heat treatment furnace, thereby guaranteeing the consistency of performance within the same batch and reducing differences in product backplate performance.

[0041] Preferably, such as Figure 4 As shown, the flipping mechanism also includes a connecting part 21, the two ends of which are fixedly connected to the two clamping parts 2 respectively. The connecting part 21 is used to fix the two clamping parts 2, thereby improving the stability of the clamping parts 2 in holding the product 100.

[0042] Preferably, such as Figure 3 and Figure 5 As shown, the heat treatment rack also includes a rack body 3. The connecting part 21 of each flipping mechanism is rotatably connected to the rack body 3, and the axis of rotation is parallel to the processing surface 110. Multiple flipping mechanisms are rotatably mounted on the rack body 3 to facilitate mass production. Each flipping mechanism can switch between vertical and horizontal states relative to the rack body 3, and it can also improve the stability of the clamping part 2 in each flipping mechanism in clamping the product 100.

[0043] Preferably, such as Figures 3-5 As shown, the rotating member 1 is rotatably connected to the clamping part 2 via the first hinge 41. The hinge facilitates 90° rotation, allowing the rotating member 1 to rotate 90° relative to the clamping part 2.

[0044] Preferably, such as Figures 3-5 As shown, the material rack body 3 is rotatably connected to the connecting part 21 via the second hinge 42. The hinge facilitates 90° rotation, allowing the connecting part 21 to rotate 90° relative to the material rack body 3.

[0045] Furthermore, the rotation direction of the rotating part 1 relative to the clamping part 2 is opposite to the rotation direction of the connecting part 21 relative to the material rack body 3. For example, if one rotation direction is clockwise, then the other rotation direction is counterclockwise. The first hinge 41 and the second hinge 42 must rotate simultaneously to achieve a 90° flip of multiple products 100.

[0046] In other implementations, the hinge may be replaced with other connectors that allow for rotation of 90° or more.

[0047] The heat treatment rack provided by this invention, during use, such as Figure 3As shown, the plate-shaped product 100 to be subjected to solution heat treatment is first clamped between every two clamping parts 2, as follows: Figure 4 As shown, the U-shaped groove on the clamping part 2 holds the product 100. At this time, the connecting part 21 is in a vertical state, and the product 100 is also placed vertically. Then, the heat treatment rack is placed in the heat treatment furnace for heat treatment. After heat treatment, the heat treatment rack is removed from the heat treatment furnace for cooling. Figure 5 As shown, after pulling the two push-pull parts 11 to both sides, the first hinge 41 and the second hinge 42 rotate 90 degrees simultaneously, causing the product 100 to flip 90 degrees, thereby immersing the product 100 horizontally into the cooling medium 300 for rapid cooling. At this time, the instantaneous cooling volume of the product 100 is the largest, ensuring the consistency of the performance of each part of the product 100. Multiple products 100 are simultaneously immersed horizontally in the cooling medium 300 to achieve batch solution heat treatment of the products 100, ensuring the consistency of the performance of the same batch of products 100 and making the performance difference between each product 100 small.

[0048] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
