Description

Technical Field

[0001] The utility model belongs to the technical field of high-frequency induction heating equipment, and in particular relates to a high-frequency induction heating coil quick connector and a quick connector group. Background Art

[0002] Electromagnetic induction heating, or induction heating for short, is a method of heating conductive materials such as metal materials. It is mainly used for metal heat processing, heat treatment, welding and melting. It uses electromagnetic induction to generate current inside the heated material, relying on the energy of these eddy currents to achieve the purpose of heating. The principle of high-frequency induction heating equipment is to use the high-frequency large current it emits to flow to the heating induction coil that is wound into a ring state or the required shape, and generate a magnetic field in the induction coil through high-frequency current. When the metal workpiece is placed in the magnetic field, due to the electromagnetic induction effect, eddy currents are generated inside the workpiece, so that the workpiece itself heats up to achieve the purpose of rapid heating.

[0003] During the high-frequency induction heating process, the induction coil will generate a lot of heat. If it is not properly cooled, the coil may overheat, causing its performance to deteriorate or even be damaged. Therefore, it is necessary to pass water through the inside of the induction coil to effectively remove the heat generated by the induction coil and maintain the coil working within the appropriate temperature range. This not only ensures the stable operation of the equipment, but also extends the service life of the induction coil.

[0004] The induction coil is relatively fixed to the induction heating equipment through the positive and negative fixed ends. Due to the structural limitations of the existing induction coils, different induction coils need to be replaced during use due to different product shapes and sizes. When replacing the induction coils, the high-frequency induction heating equipment needs to be powered off and water supply cut off. The current high-frequency induction heating equipment has integrated and split types due to different designs, so the layout of the water pipes is also different. However, most of the water-cutting methods require closing the valve at the connecting pipe, and the valve cannot be closed directly at the place where the induction coil is replaced, which not only brings certain troubles to the staff, but also reduces work efficiency and is not conducive to use.

[0005] Therefore, we propose a high-frequency induction heating coil quick connector and a quick connector assembly to solve the above technical problems. Utility Model Content

[0006] In order to solve the technical problems of the troublesome replacement of induction coils of high-frequency induction heating equipment and reduced working efficiency in the above-mentioned prior art, the utility model proposes a high-frequency induction heating coil quick connector and a quick connector group.

[0007] The technical solution adopted by the utility model is as follows:

[0008] A high-frequency induction heating coil quick connector comprises a connecting pipe and a flexible joint, wherein the connecting pipe is provided with a first valve, and the two ends of the connecting pipe are respectively provided with a first sealing joint and a second sealing joint, the flexible joint is movably sleeved on the connecting pipe between the first valve and the first sealing joint and the opening direction of the flexible joint is arranged toward the first sealing joint, an internal thread is provided on the inner side wall of the open end of the flexible joint, the first sealing joint is located in the opening of the flexible joint, and an external thread is provided on the second sealing joint.

[0009] By adopting the above technical scheme, the utility model adds a quick connector between the integrated high-frequency induction heating device and the induction coil. During installation, the first sealing connector of the pipe is connected to the electrode fixing pipe at the cooling water supply end of the integrated high-frequency induction heating device through a flexible joint, and the second sealing connector at the other end is connected to one end of the induction coil. The other end of the induction coil can be connected to the other electrode fixing pipe of the integrated high-frequency induction heating device in a common way, or another quick connector can be added for connection. During the high-frequency induction heating process, the first valve is opened so that the integrated high-frequency induction heating device can effectively take away the heat generated by the induction coil by passing water through the inside of the induction coil, and maintain the coil working within an appropriate temperature range. This not only ensures the stable operation of the equipment, but also prolongs the service life of the induction coil. When different induction coils need to be replaced to heat products of different shapes and sizes, the induction coil can be replaced by powering off the equipment and then closing the first valve to cut off the water. The utility model reduces the trouble brought to the staff by cutting off the power and water at the induction coil, and also improves the work efficiency, which is convenient for use.

[0010] In a further technical solution, a screw nut is provided on the outer fixing sleeve of the movable joint.

[0011] By adopting the above technical solution, the flexible joint is rotated by turning the nut, which is conducive to tightening the connecting tube and the electrode fixing end and is convenient to use.

[0012] In a further technical solution, the shape of the screw nut is one of a triangle, a square, a pentagon or a hexagon.

[0013] By adopting the above technical solution, the shape of the screw nut is set to different shapes, so as to adapt to different use environments and tools and facilitate use.

[0014] In a further technical solution, a protective plate is also included, wherein the protective plate is arranged in an L shape, and the connecting pipe is arranged to penetrate the protective plate.

[0015] By adopting the above technical solution, the protection plate can be provided to effectively protect the pipe, and heat radiation and splashing during the heating process can be prevented, which is of great significance for protecting equipment and operators.

[0016] In a further technical solution, the protective plate is vertically connected to a connecting plate at one end of the first sealing joint, and a bolt hole is opened on the connecting plate.

[0017] By adopting the above technical solution, the protective plate can be connected to the high-frequency induction heating equipment through the connecting plate and the bolt holes on the connecting plate, so that the connection of the protective plate is more stable, thereby improving the operating stability of the equipment.

[0018] In a further technical solution, a branch pipe is connected between the connecting pipe and the first valve and the second sealing joint, and a second valve is provided on the branch pipe.

[0019] By adopting the above technical solution, a branch pipe is arranged on the connecting pipe and a second valve is arranged on the branch pipe. It can be used on a split-type high-frequency induction heating device. By connecting a cooling water pipe to the branch pipe, water is passed through the inside of the induction coil to cool it down. When the induction coil needs to be replaced, the power is turned off and the second valve is closed. Therefore, it can be effectively used on integrated and split-type high-frequency induction heating devices, thereby improving versatility and facilitating use.

[0020] A high-frequency induction heating coil quick connector group comprises two quick connectors as described above, the two quick connectors are symmetrically arranged, and also comprises an insulating partition, the insulating partition is arranged between the two quick connectors.

[0021] By adopting the above technical solution, two quick connectors are set as a group, and an insulating partition is provided between the two quick connectors, so as to effectively isolate the positive and negative poles, prevent electrical short circuit, and ensure the safety of the staff.

[0022] In a further technical solution, a through hole is provided on the insulating partition, and connecting holes corresponding to the positions of the through holes are provided on the protective plates of the two quick connectors, and the connecting holes are connected by insulating bolts.

[0023] By adopting the above technical solution, the two protective plates are fixed as a whole by insulating bolts, which improves the stability of the quick connector group and facilitates use. The through hole is generally set as an elliptical hole. The spacing between the proximal ends of the elliptical hole is 30 cm, and the spacing between the farthest ends of the elliptical hole is 50 cm. The spacing can be adjusted to adapt to the use of high-frequency induction heating equipment with different layouts.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0025] The utility model can be adaptively installed on both integrated and split high-frequency induction heating equipment through the connecting pipe, the branch pipe and the first valve and the second valve on the connecting pipe and the branch pipe, and can ensure the normal use of the high-frequency induction heating equipment. When the induction coil needs to be replaced, the power supply and water supply can be cut off at the induction coil, which reduces the trouble to the staff, improves the work efficiency and is convenient for use.
