Description

Technical Field

[0001] This utility model relates to the technical field of heat treatment equipment for printed parts, and in particular to a heat treatment device for high-temperature alloy 3D printed parts. Background Technology

[0002] In the 3D printing process, equipment often employs a fixed heating structure. The heat conduction path is limited by the geometry of the printed part, resulting in a non-uniform temperature field for irregularly shaped parts during the forming process. Especially when printing workpieces with overhanging or hollow features, the imbalance in heat flow distribution between the solidified layer and the newly added material layer leads to a decrease in interlayer bonding strength. Furthermore, localized overheating areas can easily cause lattice distortion in the metal material, directly affecting the mechanical properties of the formed part.

[0003] In the actual heat treatment process, existing 3D printing heating devices cannot meet the heating requirements of different metal parts due to their varying shapes and sizes. When metal parts of different shapes are placed inside the container, their bottoms come into contact with the inner wall of the container, failing to form an effective heating space, which further leads to low heat treatment efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a heat treatment device for high-temperature alloy 3D printed parts to solve the problem of non-uniform temperature field generated during the forming process of irregular structural parts.

[0005] The technical solution of this utility model is: a heat treatment device for high-temperature alloy 3D printed parts, including a heat treatment box, a heating component on the heat treatment box, a support plate inside the heat treatment box, and multiple sets of support components on the support plate.

[0006] As a further improvement of this utility model, the support plate is provided with multiple threaded holes, and a lead screw is connected inside the threaded holes by threads. The support assembly is set at the top of the lead screw and is used to rotate and adjust the height of the support assembly.

[0007] As a further improvement of this utility model, the support assembly consists of multiple support units, each of which includes a support rod, a fixed plate, and a handle plate. Multiple support rods are mounted on the fixed plate, the fixed plate is mounted on the upper end of the lead screw, and the handle plate is mounted on the lower end of the lead screw. Multiple support units can be selected according to the size and shape of the printer to provide stable support for the printer, and to leave maximum space for heat treatment below.

[0008] As a further improvement of this utility model, the heating component is located at the top of the heat treatment chamber, and the heating component is connected to a ventilation component that leads into the heat treatment chamber. The airflow can be used to evenly deliver the heat generated by the heating component into the heat treatment chamber.

[0009] As a further improvement of this utility model, the heating component consists of an electric heating power controller, a conduit, a cylindrical shell, and a heating resistance wire. The two ends of the conduit are connected to the electric heating power controller and the cylindrical shell, respectively. The heating resistance wire is installed inside the cylindrical shell. The wire of the heating resistance wire passes through the conduit and is electrically connected to the electric heating power controller. The heat generated by the resistance wire is evenly delivered into the heat treatment chamber by airflow, so that a uniform temperature field is formed in the heat treatment chamber, which facilitates the heat treatment of the printed parts and improves the heating efficiency.

[0010] The ventilation assembly consists of a blower, an upper air guide pipe, and a lower air guide pipe. The two ends of the upper air guide pipe are connected to the blower and the shell, respectively, and the two ends of the lower air guide pipe are connected to the shell and the heat treatment box, respectively.

[0011] The beneficial effects of this utility model are:

[0012] 1. The multiple support units in this utility model can adjust the height by rotating the screw through the rotating handle, and adjust the support angle according to the shape and size of the printed part, so as to suspend and support the printed part, ensuring that there is a maximum heat treatment space under the printed part, so that the surface of different irregular structural parts can be heated evenly.

[0013] 2. The electric heating power controller and blower can be started using the main control box. The electric heating power controller is electrically connected to the heating resistance wire inside the cylinder shell through wires, which further heats the heating resistance wire. Airflow is introduced into the upper air duct through the blower, and the airflow is used to evenly send the heat generated by the resistance wire into the heat treatment box, so as to form a uniform temperature field in the heat treatment box, which facilitates the heat treatment of the printed parts and improves the heating efficiency.

A sealing door 103 is movably connected to one side of the heat treatment chamber 101. A heating component is provided on the heat treatment chamber 101. A support plate 201 is provided inside the heat treatment chamber 101. Multiple sets of support components are provided on the support plate 201.

[0021] The placement mechanism 200 includes a support plate 201, which has multiple threaded holes. A lead screw 202 is threadedly connected inside the threaded holes, and a support assembly is located at the top of the lead screw 202.

[0022] The support assembly consists of support rods 205, a fixed plate 204, and a handle plate 203. Multiple support rods 205 are mounted on the fixed plate 204, the fixed plate 204 is mounted on the upper end of the lead screw 202, and the handle plate 203 is mounted on the lower end of the lead screw 202.

[0023] The heating component is located at the top of the heat treatment chamber 101, and the heating component is connected to a ventilation component that leads into the heat treatment chamber 101.

[0024] The heating assembly consists of an electric heating power controller 106, a conduit 107, a cylindrical shell 108, and a heating resistance wire 109. The two ends of the conduit 107 are connected to the electric heating power controller 106 and the cylindrical shell 108, respectively. The heating resistance wire 109 is provided inside the cylindrical shell 108. The wire of the heating resistance wire 109 passes through the conduit 107 and is electrically connected to the electric heating power controller 106.

[0026] In use, the device is placed upright on the ground; bolts are used to fix the device to the ground through the reserved mounting holes 105 on the base plate 104. Depending on the shape and size of the printed part, the support assembly is raised to the same height by rotating the lead screw 202 via the handle 203, thus supporting the printed part. The electric heating power controller 106 and the blower 110 are activated using the main control box 102. The electric heating power controller 106 electrically heats the heating resistance wire 109, and airflow is introduced into the upper air duct 111 through the blower 110. The airflow carries away the high temperature generated by the heating resistance wire 109 inside the cylinder shell 108, and then enters the heat treatment chamber 101 through the lower air duct 112. The heating power can be adjusted in real time via the main control box 102, facilitating heat treatment of the printed part and improving its material properties.
