Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings of existing devices, and this invention provides a heat treatment quenching induction coil device.

[0005] This utility model is achieved through the following technical solution:

[0008] Furthermore, the fixed pressure plate includes two pressure blocks, each of which has a through hole. The water inlet pipe and the water return pipe pass through the two through holes respectively, and both pressure blocks pass through the base and are connected to the connecting bracket.

[0009] Furthermore, both pressure blocks have connection holes, and the base has multiple through holes. The connection holes are connected to the connecting bracket by bolts passing through the through holes.

[0029] Heating coil 4 Detailed Implementation

[0030] The following description of the embodiments is with reference to the accompanying drawings, which illustrate specific embodiments in which the present invention can be implemented.

[0031] like Figure 1 As shown in the figure, this embodiment discloses a heat treatment quenching induction coil device. The heat treatment quenching induction coil device includes a connecting bracket 1, a fixing plate 3, an inlet and outlet water pipe 2, and a heating coil 4. The bottom of the connecting bracket 1 is used to install on the quenching equipment. The connecting bracket 1 has an inlet and outlet water channel. One end of the inlet and outlet water pipe 2 is connected to the connecting bracket 1, and the other end of the inlet and outlet water pipe 2 extends out of the connecting bracket 1 and is connected to the heating coil 4. The inlet and outlet water pipe 2 is connected to the inlet and outlet water channel. The fixing plate 3 is sleeved on the inlet and outlet water pipe 2 and is connected to the connecting bracket 1 and pressed tightly against the inlet and outlet water pipe 2.

[0032] The heat treatment quenching induction coil device is installed on the quenching equipment via a connecting bracket 1. Cooling water flows through the inlet and return water channels within the connecting bracket 1 to the inlet and return water pipes 2, cooling the heating coil 4 located at the end of the inlet and return water pipes 2, and then flows back through the inlet and return water channels. A fixing plate 3 is connected to the connecting bracket 1 and presses firmly against the inlet and return water pipes 2, effectively strengthening the connection between the inlet and return water pipes 2 and the connecting bracket 1. This ensures full contact between the inlet and return water pipes 2 and the connecting bracket 1 without gaps, effectively reducing sparking during the production of the heat treatment quenching induction coil device, and significantly improving water leakage, thus ensuring the quality of heat treatment. Simultaneously, the connection between the inlet and return water pipes 2 and the inlet and return water channels within the connecting bracket 1 for cooling further guarantees the quality of heat treatment.

[0033] In practical applications, the heat treatment quenching induction coil device of this embodiment significantly reduces the occurrence of arcing during heating of the heating coil 4, effectively increasing its lifespan from 150,000 pieces to over 300,000 pieces, and also significantly improving the heating effect. It improves the performance, enhances the martensitic quenching microstructure, refines the grains, and significantly improves the heat treatment effect of the piston rod. Simultaneously, it effectively extends the service life of the heating coil 4, stabilizes the quenching quality, reduces replacement frequency, indirectly improves work efficiency, virtually eliminates arcing, and improves water pressure testing capabilities; currently, there is virtually no leakage.

[0034] The inlet and outlet water pipes 2 include a base 23, an inlet water pipe 21, and an outlet water pipe 22. The base 23 is connected to one end of the inlet water pipe 21 and the outlet water pipe 22 and extends outward from the outer surface of the inlet water pipe 21 and the outlet water pipe 22. The heating coil 4 is connected to the other end of the inlet water pipe 21 and the outlet water pipe 22 and is sealed at the other end of the inlet water pipe 21 and the outlet water pipe 22. One end of the inlet water pipe 21 and the outlet water pipe 22 is connected to the inlet and outlet water channels. The fixing plate 3 is sleeved on the inlet water pipe 21 and the outlet water pipe 22, and the fixing plate 3 passes through the base 23 and is connected to the connecting bracket 1 so that the base 23 is pressed between the fixing plate 3 and the connecting bracket 1.

[0035] The water inlet and return channels within the connecting bracket 1 include an inlet channel and a return channel, which are connected to the inlet pipe 21 and the return pipe 22, respectively. These channels, along with the inlet pipe 21 and the return pipe 22, form a cooling water circulation path, thereby cooling the heating coil 4. Simultaneously, the inlet pipe 21 and the return pipe 22 are installed on the base 23, making installation and connection very convenient and ensuring high stability. The base 23 is pressed between the fixing plate 3 and the connecting bracket 1, facilitating the pressing and fixing of the inlet and return pipes 2 between the connecting bracket 1 and the fixing plate 3. This installation and connection is also very convenient, with high strength and stability.

[0036] The fixed pressure plate 3 includes two pressure blocks 31, each with a through hole through which the inlet pipe 21 and the return pipe 22 pass. Both pressure blocks 31 pass through the base 23 and are connected to the connecting bracket 1. By pressing the upper and lower ends of the base 23 with the two pressure blocks 31 respectively, the installation connection between the base 23 and the connecting bracket 1 and the fixed pressure plate 3 is highly stable.

[0037] Specifically, both pressure blocks 31 have connection holes, and the base 23 has multiple through holes. Bolts pass through these through holes and connect to the connecting bracket 1. The inlet and outlet water pipes 2 are connected to the connecting bracket 1 and the fixing plate 3 by manually tightening the bolts. Workers only need to tighten the bolts to complete the installation, saving time and effort. In this embodiment, each pressure block 31 has only one connection hole, and the connection can be achieved with two bolts. The bolts are made of stainless steel. The fixing plate 3 is also made of stainless steel.

[0038] The central shaft of the heating coil 4 is used for heating. The heating coil 4 seals the ends of the inlet pipe 21 and the return pipe 22, preventing water from leaking out. Preferably, the heating coil 4 extends into the inlet pipe 21 and the return pipe 22 and is welded to their inner walls. The welding method between the heating coil 4 and the inlet and return pipes 22 eliminates leakage and ensures reliable quality. This change in welding method significantly extends the service life, thereby improving work efficiency, reducing manual labor intensity, ensuring reliable processing quality, and reducing quality risks.

[0039] The connecting bracket 1 includes a mounting plate 11 and a connecting plate 12. The bottom surface of the mounting plate 11 is mounted on the quenching equipment, and the connecting plate 12 is connected to the top surface of the mounting plate 11, forming a "⊥" shape between them. The top of the connecting plate 12 has a notch 121, into which the inlet and outlet water pipes 2 extend. A fixing plate 3 is located within the notch 121 and connected to the connecting plate 12. The connecting bracket 1 is mounted on the quenching equipment via the mounting plate 11, resulting in high installation stability. Positioning the inlet and outlet water pipes 2 and the fixing plate 3 within the notch 121 makes the overall structure more compact and facilitates installation.

[0040] The connecting bracket 1 also includes a mounting base 13, which is located within the notch 121. One side of the mounting base 13 is connected to the connecting plate 12, the inlet and outlet water pipes 2 are fitted against the mounting base 13, and the fixing plate 3 is connected to the other side of the mounting base 13. By fitting the mounting base 13 against the base 23 and using it to install the connecting fixing plate 3, the connection strength between the connecting bracket 1, the inlet and outlet water pipes 2, and the fixing plate 3 is further strengthened. This effectively reduces the sparking phenomenon during the production of the heat treatment quenching induction coil device, and the water leakage phenomenon is significantly improved, ensuring the quality of heat treatment.

[0041] The inlet and outlet water channels extend from the bottom surface of the mounting plate 11 through the mounting plate 11, and extend from the bottom of the connecting plate 12 to the notch 121. This allows cooling water to flow into the inlet and outlet water pipes 2 through the inlet and outlet water channels and cool the heating coil 4.

[0042] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
