Description

Technical Field

[0001] This utility model relates to the field of quenching device technology, and in particular to a water cooling structure suitable for rotary quenching. Background Technology

[0002] As is well known, in the manufacturing process of knives, the blade needs to be hardened to enhance its strength. This involves heating the blade and then immersing it in a quenching liquid. To prevent the base from being affected by high temperatures for extended periods, a cooling structure is designed into the base. The most effective method is water cooling, which involves embedding water channels within the base, with one end connected to an inlet pipe and the other to an outlet pipe, relying on the continuous inflow of water for cooling.

[0003] However, currently, when heating round cutting tools, a rotational heating method is chosen to achieve more uniform heating. This involves rotating the base supporting the larger end, which in turn rotates the cutting tool, thus achieving heating while rotating. If water cooling is also used, the presence of inlet and outlet pipes makes conventional water cooling structures unable to meet the design requirements for rotary quenching. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a water cooling structure suitable for rotary quenching.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A water cooling structure suitable for rotary quenching includes a base and a rotating column. The base has a mounting seat with a mounting cavity. The rotating column passes through the mounting cavity and is mounted within it via at least one bearing. The rotating column has an inlet annular groove and an outlet annular groove on its sides. The top of the rotating column is located outside the mounting cavity and has a receiving end for receiving cutting tools. The lower end of the rotating column is used to connect to an external rotating mechanism. A water storage chamber is provided within the receiving end. The water storage chamber is connected to the inlet annular groove via a first water guide channel and to the outlet annular groove via a second water guide channel. The mounting seat has an inlet pipe and an outlet pipe at corresponding positions of the inlet and outlet annular grooves.

[0007] Preferably, the inlet annular groove is located above the outlet annular groove.

[0008] Preferably, at least two clearance annular grooves are provided on the cavity wall of the installation cavity, and the clearance annular grooves are offset from the inlet annular groove and the outlet annular groove;

[0009] At least one of the clearance ring grooves is located above the inlet ring groove, and at least one of the clearance ring grooves is located below the outlet ring groove, and a sealing ring is provided inside the clearance ring groove.

[0010] By adopting the above solution, this utility model forms a water cooling channel by setting up an inlet annular groove, an outlet annular groove, a first water guiding channel, a second water guiding channel and a water storage chamber on the rotating column. This satisfies both the rotation of the rotating column and the function of water cooling. Attached Figure Description

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a mechanical connection or an electrical connection.

[0017] like Figures 1 to 3 As shown in the figure, this embodiment provides a water cooling structure suitable for rotary quenching, including a base 1 and a rotating column 2. The base 1 is provided with a mounting seat 3, and the mounting seat 3 is provided with a mounting cavity. The rotating column 2 passes through the mounting cavity and is mounted in the mounting cavity by at least one bearing 4. The side of the rotating column 2 is provided with an inlet annular groove 5 and an outlet annular groove 6, respectively. The top of the rotating column 2 is placed outside the mounting cavity and is provided with a receiving end 7 for receiving a cutting tool 100. The lower end of the rotating column 2 is used to connect to an external rotating mechanism. A water storage chamber 8 is provided in the receiving end 7. The water storage chamber 8 is connected to the inlet annular groove 5 through a first water guiding channel 9 and to the outlet annular groove 6 through a second water guiding channel 10. The mounting seat 3 is provided with an inlet pipe 11 and an outlet pipe 12 at corresponding positions of the inlet annular groove 5 and the outlet annular groove 6.

[0018] This embodiment mainly utilizes the inlet annular groove 5, outlet annular groove 6, first water guiding channel 9, second water guiding channel 10, and water storage chamber 8 established on the rotating column 2 to form a water cooling circuit. This satisfies both the rotation of the rotating column 2 and the function of water cooling. Specifically, the rotating column 2 is first rotatably connected by a bearing 4, allowing rotation between the rotating column 2 and the mounting base 3. Therefore, when the cutting tool is placed on the receiving end 7, the lower end of the rotating column 2 is connected to an external rotating mechanism, such as a synchronous belt assembly, thus satisfying the rotation of the cutting tool. As for the specific structure of the receiving end 7, it can be simply a protrusion that receives the center hole of the cutting tool 100, or it can be a clamping structure. Of course, depending on the specific structure of the cutting tool 100, the corresponding receiving end 7 will also be different. It depends on the structure of the cutting tool 100, as long as it can receive the cutting tool 100. For water cooling to be achieved, water pipes need to be connected to the inlet 11 and the outlet 12. Water first enters from the inlet 11, and a cavity is formed between the inlet annular groove 5 and the cavity wall of the installation passage. The water that enters first flows into this cavity. When the cavity is full, the water will gradually enter the storage cavity 8 through the first water guide channel 9. The storage cavity 8 is located at the receiving end 7, which will cool the receiving end 7. When the storage cavity 8 is also full, the water will enter the outlet annular groove 6 through the second water guide channel 10. The outlet annular groove 6 and the installation passage form a cavity, and finally the water will be discharged from the outlet 12. By continuously introducing cold water and discharging hot water with heat, the receiving end 7 can be continuously cooled.

[0019] Furthermore, to achieve the best cooling effect, in this embodiment, the inlet annular groove 5 is located above the outlet annular groove 6, so that the incoming cold water can cool the receiving end 7 from the beginning, making the cooling more effective.

[0020] Furthermore, to prevent water leakage, at least two clearance annular grooves 13 are provided on the cavity wall of the installation cavity in this embodiment. The clearance annular grooves 13 are offset from the inlet annular groove 5 and the outlet annular groove 6.

[0021] At least one of the avoidance ring grooves 13 is located above the water inlet ring groove 5, and at least one of the avoidance ring grooves 13 is located below the water outlet ring groove 6. A sealing ring 14 is provided in the avoidance ring groove 13. The sealing ring 14 can prevent the internal water from seeping out.

[0022] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
