Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology for castings, and more specifically, to a heat treatment mechanism for metal castings. Background Technology

[0002] During the heating process, castings are usually placed directly on the workbench, which prevents them from being heated evenly. This can negatively impact the quality of the castings and reduce their overall quality. Furthermore, most heat treatment equipment lacks convenient loading and unloading capabilities, especially when unloading castings after heat treatment. Castings cannot cool down quickly inside the heat treatment chamber, wasting time.

[0003] To address the aforementioned issues, patent document publication number CN222294118U discloses a heat treatment mechanism for metal castings, comprising a worktable, a heat treatment chamber fixedly mounted on the top surface of the worktable, a sealing door provided on the top surface of the worktable, a driving assembly provided on the surface of the sealing door, and a rotating shaft rotatably mounted inside the sealing door.

[0004] However, it still has some drawbacks in actual use. For example, although the heat treatment mechanism achieves uniform heating of the casting by rotating the casting and cooperating with the circulation pump, the mechanism itself only cools the casting by removing the placement plate and is not equipped with active cooling devices such as fans, water cooling or gas jets, resulting in low casting cooling efficiency and thus extending the production cycle. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a heat treatment mechanism for metal castings to solve the problem of low cooling efficiency of castings in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a heat treatment mechanism for metal castings, including a workbench, a heat treatment chamber on the surface of the workbench, a sealing door slidably installed on the top of the workbench, the surface of the sealing door being in contact with one side of the heat treatment chamber, and the heat treatment mechanism for metal castings further including...

[0007] Mounting bases are disposed opposite to each other on the left and right sides of the sealed door;

[0008] Rotating roller one, which is rotatably mounted on the surface of the mounting base;

[0009] A connecting shaft is fixedly connected inside the rotating roller. A portion of the surface of the connecting shaft is rotatably connected to the inner wall of the mounting base. A ventilation cavity is fixedly connected to one end of the connecting shaft along its length. An air outlet groove is provided on the surface of the ventilation cavity. One side of the ventilation cavity is in contact with the surface of the mounting base.

[0010] A mounting bracket, which is fixedly installed on the top of the mounting base;

[0011] A fan is installed on one side of the fixed frame along its length. The fan's air outlet is fixedly connected to a rigid connecting pipe. One end of the rigid connecting pipe is rotatably connected to the side of the ventilation cavity opposite the mounting base. The fan's air outlet is connected to the interior of the ventilation cavity through the rigid connecting pipe.

[0012] It also includes an adjustment component, which is disposed on the surface of the sealing door.

[0013] The adjustment assembly includes a fixed column, a motor, a gear, a second rotating roller, an annular rack, and a transmission belt. The fixed column is fixedly installed on the surface of the sealing door. The motor is located on the top of the fixed column. One side of the gear is fixedly connected to the drive shaft of the motor. The second rotating roller is rotatably installed on the side of the sealing door surface opposite to the heat treatment chamber. The annular rack is fixedly installed on the periphery of the second rotating roller, and the outer edge of the annular rack meshes with the outer edge of the gear. The second rotating roller is connected to the first rotating roller via the transmission belt.

[0014] It also includes a control terminal, which is located outside the motor.

[0015] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0016] In the above scheme, after the sealed door moves horizontally and takes the casting out of the heat treatment box, a fan set on one side of the fixed frame generates airflow, which is then sent into the ventilation cavity through a rigid connecting pipe. Finally, the airflow is output to the surface of the casting through the air outlet slots opened on the surface of the ventilation cavity to quickly cool the casting. In addition, the motor drives the gear to rotate, so that the second rotating roller can rotate synchronously under meshing action. Through the transmission belt, the connecting shaft connected to the first rotating roller and the ventilation cavity can rotate synchronously. With the control terminal controlling the direction of rotation, the ventilation cavity is rotated back and forth. Therefore, not only is the casting quickly cooled by the external airflow, but the rotation of the ventilation cavity can also expand the coverage of the airflow cooling, so that the surface of the casting is cooled evenly, improving the cooling efficiency and shortening the production cycle.

One side of the ventilation cavity 7 is in contact with the surface of the mounting base 4.

[0027] The fixing bracket 8 is fixedly installed on the top of the mounting base 4. The fixing bracket 8 prevents the fan 9 from being directly installed at one end of the ventilation cavity 7, which would cause excessive pressure on the connecting shaft 6, resulting in bending or breakage.

[0028] Fan 9 is located on one side of the fixed frame 8 along its length. The air outlet of fan 9 is fixedly connected to a rigid connecting pipe 10. One end of the rigid connecting pipe 10 is rotatably connected to the side of the ventilation cavity 7 opposite to the mounting base 4.

The rotating roller 115 is connected to the rotating roller 5 via the transmission belt 117.

[0031] It also includes a control terminal 113, which is located outside the motor 112. The control terminal 113 is a PLC controller and can preset instructions to make the motor 112 drive the gear 114 to rotate at a certain angle and then reverse, so as to realize the reciprocating rotation of the ventilation cavity 7 to adjust the air blowing range.

[0032] The working process of this utility model is as follows: When the sealing door 3 moves horizontally and brings the casting out of the heat treatment box 2, the fan 9 set on one side of the fixed frame 8 generates wind power, and sends the wind power into the ventilation cavity 7 through the rigid connecting pipe 10. Finally, the wind power is output to the surface of the casting through the air outlet groove opened on the surface of the ventilation cavity 7 to quickly cool the casting. In addition, the motor 112 drives the gear 114 to rotate, so that the rotating roller 115 can rotate synchronously under the meshing action. Through the transmission belt 117, the connecting shaft 6 connected to the rotating roller 5 and the ventilation cavity 7 can rotate synchronously. With the control terminal 113 controlling the direction of rotation, the ventilation cavity 7 is repeatedly flipped.
