Description

Technical Field

[0001] The utility model relates to a temperature reduction precooling device, belonging to the technical field of cooling devices. Background Art

[0002] In the automotive hot forming industry, galvanized sheets are favored for their excellent corrosion resistance and are widely used in the manufacture of various products. However, during direct hot stamping, galvanized sheets are prone to cracking. In order to avoid the occurrence of cracks, the current process used in the hot forming industry is to first heat the galvanized sheet, then pre-cool it, and finally perform stamping. This method reduces the occurrence of cracks to a certain extent, but the existing pre-cooling devices on the market still have many shortcomings.

[0003] Specifically, the pre-cooling devices on the market often affect the production rhythm during the production process, resulting in an inability to adapt to the needs of large-scale mass production. In addition, the cooling water often splashes and diffuses during pre-cooling, and the water particles are large, which not only leads to uneven cooling of the sheets, but also may pollute the production environment. What is more serious is that the cooling water after cooling is often not effectively recycled, which not only wastes resources but also increases the operating costs of the enterprise.

[0004] Therefore, in order to improve production efficiency and product quality and reduce production costs, the industry urgently needs a new type of temperature reduction and pre-cooling device. Utility Model Content

[0036] The principles and features of the present invention are described below in conjunction with examples. The examples are only used to explain the present invention and are not used to limit the scope of the present invention.

[0037] like Figure 1 - Figure 8 As shown, this specific embodiment provides a temperature reduction pre-cooling device, which is mainly used for pre-cooling galvanized sheet materials to ensure uniform cooling during the production process and improve product quality.

[0038] The temperature reduction precooling device mainly includes a precooling box 100 and an atomization generating system located in the precooling box 100. The precooling box 100 includes a main frame and an appearance sheet metal component arranged outside the main frame, and a precooling groove 101 with a U-shaped cross section is arranged on the top thereof. The width and depth of the precooling groove 101 are designed according to the size of the object to be precooled to ensure that the object can be stably placed in the groove.

[0039] A first spray compartment 102 and a second spray compartment 103 are symmetrically arranged on both sides of the precooling groove 101. The two spray compartments are connected to the precooling groove 101 through the first spray outlet and the second spray outlet, respectively. A mesh plate 200 is installed on both the first spray outlet and the second spray outlet. The mesh plate 200 adopts a fine grid design, which can evenly distribute the atomized gas and prevent direct droplets from impacting the objects to be precooled.

[0040] The atomization generation system includes an atomization generator 300 and a control system. The atomization generator 300 is responsible for generating atomized gas, and its atomization outlet is connected to the first spray compartment 102 through the first branch pipe 400, and its atomization outlet is connected to the second spray compartment 103 through the second branch pipe 500. The atomized gas generated by the atomization generator 300 enters the first spray compartment 102 and the second spray compartment 103 respectively through the first branch pipe 400 and the second branch pipe 500, and then enters the precooling groove 100 after passing through the mesh plates 200 on the first spray outlet and the second spray outlet. The control system accurately adjusts the atomization amount, atomization speed and spray time of the atomization generator 300 according to the precooling requirements to ensure uniform distribution of the atomized gas in the precooling groove 101.

[0041] In order to further enhance the diffusion effect and coverage of the atomized gas, fans 600 are further provided on the first branch pipe 400 and the second branch pipe 500. These fans 600 can forcefully blow the atomized gas generated by the atomization generator 300 into the first spray compartment 102 and the second spray compartment 103, thereby further improving the precooling effect and the working efficiency of the device.

[0042] In addition, a receiving space 104 is provided at the bottom of the precooling box 100, and the atomizing generator 300 is arranged in the receiving space 104, which fully utilizes the internal space of the precooling device and makes the overall structure more compact.

[0043] In order to improve the accuracy and efficiency of precooling, a temperature sensor and a humidity sensor are also provided inside the precooling groove 101. The temperature sensor can monitor and feed back the temperature information inside the precooling groove 101 to the control system in real time, and the control system automatically adjusts the working state of the atomization system according to the information. The humidity sensor is used to monitor the humidity of the atomized gas in real time and is connected to the control system to control the amount of atomization gas output by the atomization generator 300, thereby maintaining a suitable humidity.

[0044] In order to collect and discharge the excess atomized liquid, a water guide groove and a drain port are provided at the bottom of the pre-cooling groove 101. These designs not only help to keep the pre-cooling groove 101 clean, but also have the function of cooling water recycling, realize the recycling of resources, and reduce environmental pollution.

[0045] In order to improve the precooling efficiency and reduce heat exchange, a heat preservation layer is also provided on the outer wall of the precooling box 100. The heat preservation layer is made of high-efficiency heat preservation material, which can effectively reduce the heat loss during the precooling process and improve the precooling efficiency.

[0046] In order to facilitate the adjustment of the spray direction and range and achieve a more uniform pre-cooling effect, the angles of the mesh plates 200 on the first spray outlet and the second spray outlet can also be adjusted as needed.

[0047] The cooling precooling device provided in this specific embodiment has a compact structure, is easy to operate, and has a uniform and efficient precooling effect. By accurately controlling the working state of the atomization generation system and combining the real-time monitoring of the temperature sensor and the humidity sensor, it is possible to achieve accurate precooling of the galvanized sheet material, thereby improving product quality and production efficiency. At the same time, the device also has a cooling water recovery function and good thermal insulation performance, which helps to achieve resource recycling and energy conservation and emission reduction.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
