Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology for metal materials, and in particular to a spray cooling device for metal heat treatment. Background Technology

[0002] When metals are heat-treated at high temperatures, phenomena such as grain growth and phase transformation occur, thereby changing the grain structure and properties of the metal. Cooling is used to protect the metal structure, release stress, control metal properties, and improve production efficiency. Through proper cooling, it is possible to ensure that the metal plate has good performance and quality. In the use of existing metal heat treatment cooling equipment, when the metal material is overheated and enters the water, some of the water evaporates and turns into water vapor. This process repeats itself, and the water becomes less and less, affecting the cooling of the metal material.

[0003] The utility model patent with publication number CN220619006U provides a cooling device for heat treatment of metal materials. By setting a liquid level sensor, the heat-treated metal material is placed in water for cooling. When the metal material is overheated, some of the water evaporates and turns into water vapor. This process repeats, and the water level gradually decreases. If the water level cannot reach the level of the liquid level sensor, the liquid level sensor will transmit a signal to a signal receiving device. The signal receiving device will then control the water control actuator to draw water from the water supply pipe and add it to the tank through the delivery pipe until the water level reaches the liquid level sensor. This realizes the automatic water filling function of the device and achieves the effect of saving time.

[0004] However, when cooling metal materials, they are placed directly in water. This causes the water around the metal materials to heat up rapidly, which reduces the cooling efficiency of the water and thus affects the overall cooling efficiency of the metal materials. Utility Model Content

[0005] The purpose of this invention is to provide a spray cooling device for metal heat treatment, which solves the problem that when metal materials are cooled, they are directly placed in water, which causes the water around the metal materials to heat up rapidly, reducing the cooling efficiency of the metal materials.

[0006] To achieve the above objectives, this utility model provides a spray cooling device for metal heat treatment, including a cooling box and a mobile cooling assembly. The mobile cooling assembly includes a rotating shaft, a disc, and multiple cooling structures. The rotating shaft is rotatably disposed above the cooling box, and the disc is fixedly connected to the rotating shaft. The multiple cooling structures are arranged in a ring at intervals on the side of the disc. Each cooling structure includes a fixed column, a connecting ring, a U-shaped connecting frame, and a support plate. One end of the fixed column is fixedly connected to the disc, and the connecting ring is rotatably connected to the fixed column and sleeved on the outside of the fixed column. The top of the U-shaped connecting frame is fixedly connected to the connecting ring, and both ends of the U-shaped connecting frame are fixedly connected to the two sides of the support plate, respectively.

[0007] Two fasteners are symmetrically arranged above the support plate. Each fastener includes a mounting base, an elastic rod, and a movable frame. The mounting base is fixedly installed on the support plate, and the movable frame is slidably connected to the support plate. The two ends of the elastic rod are fixedly connected to the mounting base and the movable frame, respectively. The elastic rod is located between the mounting base and the movable frame, and an arc-shaped guide surface is provided at the end of the movable frame away from the elastic rod.

[0008] The elastic rod includes an outer cylinder, a spring, and an inner cylinder. One end of the outer cylinder is fixedly connected to the mounting base, one end of the inner cylinder is slidably connected to the other end of the outer cylinder, and the other end of the inner cylinder is fixedly connected to the movable frame. The two ends of the spring are fixedly connected to the inner cylinder and the outer cylinder, respectively, and the spring is located inside the outer cylinder.

[0009] The mobile cooling assembly also includes a mounting plate and multiple spray heads. The mounting plate is fixedly installed above the cooling box, and the multiple spray heads are spaced apart on the side of the mounting plate.

[0010] The mobile cooling assembly also includes a placement box, which is fixedly installed above the cooling box, and the interior of the placement box is provided with multiple partitions at intervals.

[0011] This utility model discloses a spray cooling device for metal heat treatment. When metal needs to be cooled, the metal is placed on a support plate, and the rotating shaft drives the disc to rotate, causing the support plate to move into the interior of the cooling tank, thereby cooling the metal. Furthermore, the metal continuously moves in the water under the movement of the support plate, ensuring constant contact with the cooler water, thus improving the cooling efficiency. This invention solves the problem that when metal materials are directly placed in water for cooling, the surrounding water rapidly heats up, reducing the cooling efficiency of the metal.

Detailed Implementation

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of a spray cooling device for metal heat treatment according to this utility model. Figure 2 This is a schematic diagram of the structure of a spray cooling device for metal heat treatment according to this utility model from another perspective. Figure 3 This is a structural cross-sectional view of a spray cooling device for metal heat treatment according to this utility model.

[0019] This utility model provides a spray cooling device for metal heat treatment, including a cooling box 100 and a movable cooling assembly; the movable cooling assembly includes a rotating shaft 210, a disc 220, multiple cooling structures, a mounting plate 280, multiple spray heads 290 and a placement box 310, the cooling structure includes a fixed column 230, a connecting ring 240, a U-shaped connecting frame 250 and a support plate 260, and a fixing device, the fixing device includes a mounting base 271, an elastic rod and a movable frame 272, the elastic rod includes an outer cylinder 273, a spring 274 and an inner cylinder 275;

[0020] In this specific embodiment, the rotating shaft 210 is rotatably disposed above the cooling box 100, the disc 220 is fixedly connected to the rotating shaft 210, a plurality of cooling structures are arranged in a ring at intervals on the side of the disc 220, one end of the fixing column 230 is fixedly connected to the disc 220, the connecting ring 240 is rotatably connected to the fixing column 230, the connecting ring 240 is sleeved on the outside of the fixing column 230, the top of the U-shaped connecting frame 250 is fixedly connected to the connecting ring 240, and the two ends of the U-shaped connecting frame 250 are respectively fixedly connected to the two sides of the support plate 260. The rotating shaft 210 can be driven to rotate by a motor. When the rotating shaft 210 rotates, it can drive the disc 220 to rotate. The connecting ring 240 can rotate relative to the fixed column 230. The U-shaped connecting frame 250 is used to connect the support plate 260. The support plate 260 is used to support the metal. Since the connecting ring 240 can rotate relative to the fixed column 230, the support plate 260 can maintain a horizontal state under its own weight. When metal needs cooling, it is placed on the support plate 260. The rotating shaft 210 drives the disc 220 to rotate, causing the support plate 260 to move into the cooling tank 100, thereby cooling the metal. The metal continuously moves in the water as the support plate 260 moves, ensuring constant contact with the cooler water, thus improving cooling efficiency. This solves the problem that directly immersing the metal in water during cooling causes the surrounding water to heat up rapidly, reducing cooling efficiency. As the disc 220 rotates, the support plate 260 automatically moves out of the cooling tank 100, allowing the operator to easily remove the cooled metal.

[0021] Furthermore, two retainers are symmetrically arranged above the support plate 260. The mounting base 271 is fixedly installed on the support plate 260, and the movable frame 272 is slidably connected to the support plate 260. The two ends of the elastic rod are fixedly connected to the mounting base 271 and the movable frame 272 respectively. The elastic rod is located between the mounting base 271 and the movable frame 272, and an arc-shaped guide surface is provided at the end of the movable frame 272 away from the elastic rod. The retainers are used to fix the metal. The elastic rod has elasticity and extensibility. When the metal is cooled, it is placed between the two movable frames 272. The metal compresses the two movable frames 272, and the two movable frames 272 move to both sides under the action of the arc-shaped guide surface. The elastic rod is compressed and elastic, causing the movable frames 272 to hold the metal and fix it between the two movable frames 272.

[0022] Specifically, one end of the outer cylinder 273 is fixedly connected to the mounting base 271, one end of the inner cylinder 275 is slidably connected to the other end of the outer cylinder 273, and the other end of the inner cylinder 275 is fixedly connected to the movable frame 272. The two ends of the spring 274 are fixedly connected to the inner cylinder 275 and the outer cylinder 273 respectively, and the spring 274 is located inside the outer cylinder 273. The inner cylinder 275 can slide relative to the outer cylinder 273, and the spring 274 supports the inner cylinder 275 to secure the metal between the two movable frames 272.

[0023] The mounting plate 280 is fixedly installed above the cooling tank 100, and multiple spray heads 290 are spaced apart on the side of the mounting plate 280. Each spray head 290 is connected to a water pipe. When the metal is cooled and moved out of the cooling tank 100, it is sprayed with water from the spray heads 290, which cleans impurities from the metal surface and simultaneously cools the metal.

[0024] In addition, the placement box 310 is fixedly installed above the cooling tank 100, and multiple partitions 320 are spaced apart inside the placement box 310. The placement box 310 is used to place the cooled metal for draining, and the bottom of the placement box 310 is provided with filter holes, allowing water to flow back into the cooling tank 100 through the filter holes. The partitions 320 are used to isolate the metal pieces to prevent them from affecting each other.

[0025] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
