Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology, specifically to a heat treatment device for alloy castings. Background Technology

[0002] Metal heat treatment refers to the process of slowly heating metal to a certain temperature, holding it for a sufficient time, and then cooling it at an appropriate rate. Metal heat treatment generally does not change the shape or overall chemical composition of the workpiece, but rather imparts or improves its performance characteristics by altering the internal microstructure or the surface chemical composition. To ensure that metal workpieces possess the required mechanical, physical, and chemical properties, in addition to the appropriate selection of materials and various forming processes, heat treatment is often indispensable.

[0003] Existing heat treatment apparatuses for alloy castings have limited capacity for variation in cooling rate. However, the cooling rates for heat treatment can vary significantly among different types of alloy castings, and current heat treatment apparatuses struggle to meet the demands of such large variations in cooling rate. Therefore, a new heat treatment apparatus for alloy castings is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a heat treatment device for alloy castings, which can adjust the number of working cooling pipes according to the type of alloy casting or heat treatment requirements, thereby better meeting actual usage needs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat treatment device for alloy castings, comprising a furnace body, a cooling pipe assembly installed on the side wall of the furnace body, wherein each cooling pipe in the cooling pipe assembly is independently set, each water outlet end of the cooling pipe assembly is connected to the same water outlet pipe, and each water inlet end of the cooling pipe assembly is connected to the same water inlet pipe. The furnace body is equipped with a control unit, which is used to adjust the number of water inlets opened and closed in the cooling tube assembly. When slow cooling is required, the number of water inlets opened in the cooling tube assembly can be reduced, and when rapid cooling is required, the number of water inlets opened in the cooling tube assembly can be increased, thereby controlling the number of working cooling tubes.

[0006] Preferably, the control unit includes a sleeve installed in communication with the water inlet pipe, and the water inlet end of the cooling pipe assembly is also installed in communication with the sleeve. A piston is installed inside the sleeve, and an electric push rod is installed on the furnace body to drive the piston to move. The number of opening and closing of the water inlet end of the cooling pipe assembly is controlled by adjusting the position of the piston in the sleeve.

[0007] Preferably, the control unit includes a manifold sleeve installed in connection with the water inlet pipe, the water inlet end of the cooling pipe assembly is also installed in connection with the manifold sleeve, and a valve is installed on each water inlet end of the cooling pipe assembly.

[0008] Preferably, a protective shell is installed on the furnace body to protect the control unit from damage.

[0009] Preferably, the cooling pipe assembly is composed of multiple serpentine pipes stacked together or multiple coils arranged in parallel.

[0010] Preferably, a support is installed at the bottom of the furnace body to provide support.

[0011] Preferably, the water outlet pipe passes through the side wall of the furnace body, and the control unit is located outside the furnace body.

[0012] This utility model provides a heat treatment device for alloy castings, which has the following advantages compared with the prior art: 1. By adding a cooling pipe assembly and a control unit, the number of cooling pipes in the assembly can be adjusted using the control unit. When some castings need slow cooling, a small number of cooling pipes can be opened, and when some castings need rapid cooling, most or all of the cooling pipes can be opened to accelerate the cooling rate. This allows for the control of the number of working cooling pipes and better meets actual usage needs.

[0013] 2. By installing a protective shell on the furnace body, the control unit can be protected from damage, thus improving the safety of the device. Attached Figure Description

[0016] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0017] Example 1 Different types of castings have different cooling rate requirements after high-temperature heat treatment. To better meet the cooling needs of various types of castings, this embodiment provides a heat treatment apparatus for alloy castings, such as... Figures 1-4 As shown, the furnace includes a furnace body 1. A support 2 is installed at the bottom of the furnace body 1 to provide support, so that the furnace body 1 is more than 10cm away from the ground. A cooling pipe assembly 3 is installed on the side wall of the furnace body 1. Each cooling pipe in the cooling pipe assembly 3 is independently set. All water outlets of the cooling pipe assembly 3 are connected to the same water outlet pipe 4. The water outlet pipe 4 passes through the side wall of the furnace body, and the other end of the water outlet pipe 4 can be connected to a hot water storage tank. All water inlet ends of the cooling pipe assembly 3 are connected to the same water inlet pipe 5.

[0018] Cold water can be injected into the inlet pipe 5 by an external water pump. The cold water then flows along the cooling pipe assembly 3. Since the cooling pipe assembly 3 is located inside the furnace body 1, the heat of the furnace body 1 is carried away from the water supply pipe 4 after exchanging with the cold water, thus reducing the temperature inside the furnace body 1.

[0019] A control unit 6 is provided on the furnace body 1. The control unit 6 is located outside the furnace body 1 and is used to adjust the number of opening and closing of the water inlet end in the cooling tube group 3. When slow cooling is required, the number of opening of the water inlet end in the cooling tube group 3 can be reduced, and when rapid cooling is required, the number of opening of the water inlet end in the cooling tube group 3 can be increased, thereby realizing the control of the number of working cooling tubes.

[0020] Different types of castings have different cooling rate requirements after high-temperature heat treatment. When some castings require air cooling, the furnace body 1 door can be opened directly; Figure 2 To determine the orientation, the control unit 6 adjusts the number of cooling pipes in the cooling pipe group 3 that are open. When some castings need to be cooled slowly (without air cooling to prevent oxidation of the metal castings by oxygen in the air at high temperatures), a small number of cooling pipes are opened, such as using only one cooling pipe. When some castings need to be cooled quickly, most or all of the cooling pipes are opened, such as using five cooling pipes, to accelerate the cooling rate. The control unit 6 can adjust the number of working cooling pipes, which can better meet the actual use needs.

[0021] In this embodiment, the control unit 6 includes a sleeve 63 connected to the water inlet pipe 5, and the water inlet end of the cooling pipe assembly 3 is also connected to the sleeve 63. A piston 62 is installed inside the sleeve 63, and an electric push rod 61 for driving the piston 62 is installed on the furnace body 1. The number of opening and closing of the water inlet end of the cooling pipe assembly 3 is controlled by adjusting the position of the piston 62 in the sleeve 63. Figure 2 To determine the orientation, when slow cooling is required, the electric push rod 61 is activated, causing the piston 62 mounted on its movable end to move to the right, leaving only the water inlet of the last cooling pipe open, while the water inlets of the remaining cooling pipes are closed by the piston 62. Only one cooling pipe in the furnace body 1 is used for water cooling. When rapid cooling is required, the electric push rod 61 is activated, causing the piston 62 to move to the left, until the piston 62 moves to the position indicated by the piston 62. Figure 2 At the position shown, the water inlets of multiple cooling pipes are all open, and only multiple cooling pipes in the furnace body 1 are water-cooled; the number of working cooling pipes can be adjusted to better meet actual usage needs.

[0022] Furthermore, a protective shell 7 is installed on the furnace body 1 to protect the control unit 6 from damage.

[0023] Furthermore, cooling pipe assembly 3 consists of multiple serpentine pipes stacked together, such as... Figure 1 and Figure 3 As shown in the diagram. Cooling tube assembly 3 can also be composed of multiple coils arranged in parallel, such as... Figures 7-8 As shown.

[0024] Example 2 refer to Figures 5-6 The control unit 6 is basically the same as that in embodiment 1, except that the control unit 6 includes a manifold 6a that is connected to the water inlet pipe 5 and installed in connection with the water inlet end of the cooling pipe assembly 3. A valve 6b is installed on each water inlet end of the cooling pipe assembly 3.

[0025] by Figure 2 Using the reference for determining orientation, when slow cooling is required, one or two valves 6b can be opened, and only one or two cooling pipes in the furnace body 1 will be used for water cooling. When rapid cooling is required, all valves 6b can be opened, and all cooling pipes in the furnace body 1 will be used for water cooling. This allows for the control of the number of working cooling pipes, which can better meet the actual usage needs.

[0026] In this embodiment, a protective shell 7 is installed on the furnace body 1 to protect the control unit 6 from damage.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
