The embodiment of the utility model discloses a quenching inductor, which has a structure shown in figures 1-3 and comprises a first induction coil 11, a second induction coil 12, a connecting piece 13, a conductive piece 14, a fixed block 15 and a hollow shell 16.
Specifically, the first induction coil 11 and the second induction coil 12 are welded into a whole through the connecting piece 13 to form an annular body, a heating space surrounded by the inner side of the annular body is of an 8-shaped structure, and the diameter of the first induction coil 11 is larger than that of the second induction coil 12 and is matched with the size of a workpiece. With this design, when a workpiece having two members of different sizes is heated, the first induction coil 11 and the second induction coil respectively heat the members of different sizes of the workpiece by moving the quenching inductor, so that the members of different sizes of the workpiece can be uniformly heated.
And two conductive pieces 14 are symmetrically arranged at the bottom of the first induction coil and are used for connecting a power supply with the induction coils of the induction coils. Both conductive members 14 have a first conductive plate 141, a second conductive plate 142, and an insulating member 143.
Wherein, the first conductive plate 141 has a coil connection end at one end for connecting with the induction coil of the first induction coil 11, and a power connection end at the other end for electrically connecting with a power supply.
The second conductive plate 142 is disposed side by side with the first conductive plate 141. One end of the second conductive plate 142 is provided with a coil connecting end connected with the induction coil of the second induction coil 12; the other end is provided with a power connection end which is electrically connected with the power supply.
The insulating plate 143 is interposed between the first conductive plate 141 and the second conductive plate 142.
With the above structure, the induction coil of the first induction coil 11 and the induction coil of the second induction coil form a loop with the power supply, that is, the induction coils of the first induction coil 11 and the second induction coil 12 are connected in parallel. The mode of parallel connection is adopted, so that the two induction coils can be prevented from interfering with each other when in work and influencing the heating effect.
The fixing block 15 is welded on the arc top of the second induction coil 12 to increase the stability of the inductor.
As an optimized solution of this embodiment, the side edges of the first induction coil 11 and the second induction coil 12 are provided with annular hollow shells 16, and the annular cavity of each of the hollow shells corresponds to the size of the annular hole of the annular body formed by connecting the first induction coil 11 and the second induction coil 12. The hollow housing 16 has a first cavity 161 and a second cavity 162 that are not communicated with each other, and correspond to the positions of the first induction coil 11 and the second induction coil 12, respectively, that is, the boundary of the first cavity 161 and the second cavity 162 is located at the connection position of the first induction coil 11 and the second induction coil 12. The first cavity 161 and the second cavity 162 are symmetrically provided with a water inlet pipe and a water outlet pipe.
Generally, a workpiece heated to a high temperature radiates heat to the outside. In order to prevent the quenching inductor from being overheated and incapable of being used due to radiation heat, the hollow shell 16 is connected with a water source by adopting the structure, so that the quenching inductor can be effectively cooled; meanwhile, the hollow shell 16 is composed of a first cavity 161 and a second cavity 162 which correspond to the first induction coil 11 and the second induction coil 12 respectively, the first cavity 161 and the second cavity 162 are not communicated with each other, when the induction coils work, the cavities corresponding to the induction coils are communicated with a water source, the induction coils are cooled, water resources can be saved, and waste is avoided.
The operation of the embodiment of the present invention will be described in detail below using a camshaft as an example.
It is known from the prior art that the distance between the induction coil and the workpiece contour influences the heating effect of the quench inductor. When a circular quenching inductor is used for heating a camshaft, the induction coil must meet the requirement of cam passing of the camshaft, when a journal is heated, the distance between the induction coil and the contour of the journal is increased, and the heating effect cannot meet the processing requirement.
By using the quenching inductor of the embodiment of the utility model, when the journal is heated, the quenching inductor is moved to enable the center of the second induction coil 12 to coincide with the rotation center of the camshaft, so as to perform induction heating, and the heating effect of the journal can also meet the processing requirement. Therefore, the inductor heater provided by the embodiment of the utility model is more suitable for quenching machining of the cam shaft workpiece compared with the conventional circular quenching inductor.
As can be seen from the above description, the beneficial effects of the present invention are: by using the first induction coil and the second induction coil with different diameters, when in processing, the corresponding induction coil is selected according to the diameter of the workpiece for induction heating, so that parts of the workpiece with different sizes can be uniformly heated to meet the processing requirement; furthermore, the induction coils of the first induction coil and the second induction coil are connected in parallel, so that the problem that the workpiece is not uniformly heated due to the influence of the other induction coil when the workpiece is heated can be solved; finally, the first induction coil and the second induction coil are both provided with hollow shells, and when a water source is connected, the induction coils can be prevented from being overheated; simultaneously, hollow shell comprises first cavity and the second cavity that does not communicate each other, and when the induction coil during operation, the water source is put through to corresponding cavity, cools off the induction coil, can save the water resource, avoids extravagant.
The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are merely exemplary embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
