Technical Field

[0001] The invention relates to an air outlet guide auxiliary fixture applied to heat treatment equipment, belonging to the technical field of air guide structures in heat treatment equipment. Background Art

[0002] Heat treatment refers to a metal thermal processing technology that uses heating, heat preservation and cooling to obtain the desired structure and performance of materials in the solid state. In the process from the Stone Age to the Bronze Age and the Iron Age, the role of heat treatment has gradually been recognized by people.

[0003] Commonly used heat treatment equipment mainly includes various heating furnaces and heating devices. Among the heat treatment equipment, the most widely used are various resistance furnaces, which use electricity as energy and heat the workpiece by converting electrical energy into thermal energy through the electric heating elements in the furnace. Heating devices include direct electric heating devices, contact electric heating devices, flame heating devices, induction heating devices, and laser heating devices.

[0004] Generally, there is a circulating air outlet in the heat treatment equipment, through which high-temperature airflow can be directly blown into the material to be heat treated inside. However, the shapes of the materials to be treated are different, and the appearance has different concave-convex, curved surface and other structures, which leads to poor heating uniformity on the outer surface of the material to be heat treated. Especially when there is a large change in the temperature change curve, the uniformity of the internal quenching structure phase change will be affected. Summary of the invention

In view of the problem that the air outlet end of the traditional heat treatment equipment cannot be adjusted according to the shape of the load, resulting in uneven heating of the outer surface of the load and poor uniformity of the internal structure transformation, an air outlet guiding auxiliary fixture for use in the heat treatment equipment is proposed.

[0019] Figure 1 It is a structural schematic diagram of the gas outlet guide auxiliary fixture of the present invention applied to heat treatment equipment.

[0020] Figure 2 is a schematic diagram of a sealed furnace chamber.

[0021] Figure 3 It is a schematic diagram of the extended air duct. DETAILED DESCRIPTION

[0022] The present invention provides an exhaust guide auxiliary fixture for heat treatment equipment. The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings to make it easier to understand and grasp.

[0023] Gas outlet guide auxiliary fixtures used in heat treatment equipment, such as Figure 1 and Figure 2 As shown, the heat treatment equipment comprises a sealed furnace chamber 1, a loading support seat 2 is arranged in the sealed furnace chamber 1, a plurality of air outlets 3 for air circulation are arranged on the inner wall of the sealed furnace chamber 1 toward the loading support seat 2, and an electric heating source 4 is arranged in the sealed furnace chamber 1.

[0024] In the traditional heat treatment process, the workpiece 5 to be heat treated is directly loaded on the loading support seat 2, the furnace chamber is sealed, the electric heating source 4 performs the heating operation, and the air outlet 3 circulates the air in the furnace and sprays the workpiece 5 with air flow, thereby realizing the internal structure formation. However, due to the concave and convex morphological structures of the workpiece 5, there are large differences in the hot air shock received on its outer surface, which leads to differences in the uniformity of the internal structure formation, affecting the product quality.

[0025] In this case, any air outlet 3 is provided with a detachably assembled extended air duct 6 .

[0026] Specific implementation principle and process description:

[0027] The relative air outlet position is adjusted according to the shape characteristics of the workpiece 5, that is, by connecting the extended air duct 6 with the air outlet 3, the hot air travel between the air outlet end of the extended air duct 6 and the outer surface of the workpiece 5 can be controlled, thereby ensuring that the outer surface of the workpiece 5 is evenly impacted by the hot air, the internal structure is formed more evenly, and the product quality is greatly improved.

[0028] In a specific embodiment, Figure 3 As shown, the extended air duct 6 includes an air guide end 7 for guiding the air outlet.

[0029] Specifically, this embodiment is suitable for some workpieces with inner concave cavities. Simply extending the stroke of the air outlet 3 cannot meet the demand for hot air to directly hit such inner concave cavities. Therefore, the design of the air guide end 7 is adopted to adjust the wind direction according to the needs of the workpiece, so that the temperature of the outer surface of the workpiece is more uniform and the quality is stable and reliable.

[0030] The air guide end 7 and the extended air duct 6 are detachable structures, and the air guide end 7 can be replaced according to the needs to adapt to the actual workpiece shape requirements.

[0031] In a specific embodiment, a regulating valve body 8 for adjusting the air volume is provided on the extended air duct 6 .

[0032] Specifically, the regulating valve body 8 can realize coordinated adjustment of all extended air ducts 6. For example, when the workpiece 5 has features such as concave, concave cavity, plane, curved surface, etc., the air volume can be appropriately adjusted according to the surface area of ​​any feature body to meet the uniformity of wind force on the feature body.

[0033] More specifically, the air outlet 3 and the extended air duct 6 include at least threaded connection, snap-fit ​​connection, and pin-bolt locking connection; the air guide end 7 and the extended air duct 6 include at least threaded connection, snap-fit ​​connection, and pin-bolt locking connection. The extended air duct is made of a high-temperature resistant material, which includes at least graphite, molybdenum alloy, and ceramic.

[0034] As is known to all, the temperature inside the sealed furnace chamber 1 of the heat treatment equipment is very high. Ordinary profiles will deform and cannot be used in such a high temperature environment. In this case, graphite, molybdenum alloy, ceramic and other profiles are used to form the extended air duct 6, so as to meet the high temperature resistance of the extended air duct 6 and meet its service life requirements.

[0035] Through the above description, it can be found that the present invention is applied to the air outlet guiding auxiliary fixture of the heat treatment equipment. By extending the air duct, the air outlet position of the air outlet can be adjusted, and the matching air outlet stroke is adjusted according to the shape characteristics of the heat treatment workpiece, so that the outer surface of the heat treatment workpiece is evenly affected by the wind force, the heat treatment forms a uniform and stable organization, and the product quality is greatly improved. It is equipped with an air guide end, and the air outlet end can be guided to meet the needs of heat treatment workpieces with direct blowing blind spots, and the air outlet fully covers the outer surface. The regulating valve body can adjust the air outlet volume to further meet the wind force uniformity requirements. The overall design is simple and ingenious, so that the heat treatment equipment meets the shape requirements of the heat treatment workpiece, and the detachable operation is flexible and efficient, which is suitable for promotion and application.

[0036] The above fully describes the technical solution of the present invention. It should be noted that the specific implementation of the present invention is not limited to the above description. All technical solutions formed by ordinary technicians in the field using equivalent or equivalent transformations in structure, method or function based on the spirit of the present invention fall within the protection scope of the present invention.
