Description

Technical Field

[0001] The utility model relates to an auxiliary device for a quenching machine, in particular to a cooling integrated block for an induction coil of a quenching machine. Background Art

[0002] Induction quenching refers to a heat treatment method in which a workpiece is heated by generating eddy currents in the workpiece using electromagnetic induction, and after the surface of the workpiece is locally heated at a certain frequency, it is then cooled to obtain a surface hardened layer. Therefore, it is widely used in the machining industry. The induction quenching machine uses induction heating. The workpiece is placed in the inductor, and an induction coil (hollow copper tube with water-cooling) that inputs an alternating current of a certain frequency. An induction current of the same frequency is generated in the workpiece through the alternating magnetic field, which can quickly heat the surface of the workpiece. At the same time, the connecting plate on the quenching machine where the inductor is installed will also generate a very high temperature. Currently, a backing plate 03 is provided inside the two symmetric connecting plates 01 on the outer wall of the rectifier transformer of the quenching machine, and an electromagnetic induction coil 04 is installed on the outer side. A cooling water pipe 02 is welded to the outer side of the connecting plate 01 (as Figure 1 and Figure 2 shown). The cooling water pipe 02 can play a certain cooling role for the connecting plate 01, but the overall effect on the connecting plate 01 is very limited. Since the cooling water pipe 02 is on the outer side edge of the connecting plate 01, the cooling range of the cooling water pipe 02 is only on the outer side of the connecting plate 01, and the entire connecting plate 01 cannot be comprehensively cooled. Therefore, when the quenching machine is working, there will still be a very high temperature at the installation connection between the electromagnetic induction coil 04 and the rectifier transformer, which will burn out the installation bolts of the electromagnetic induction coil 04, and even damage the threaded holes of the rectifier transformer of the quenching machine body. Once the threaded holes are damaged, it will affect the installation stability of the electromagnetic induction coil 04, and there will be arcing due to poor contact, damaging the quenching machine, or the quenching equipment cannot be used normally, and it will affect the quenching effect of the parts, and the qualified rate of product quenching will decrease significantly. Content of the Utility Model

[0003] In view of the above technical problems, the utility model provides an integrated block to replace the connecting plate in the prior art, which is used for the connection and installation cooling of the inductor of the quenching machine, so as to improve the cooling effect at the connection between the induction coil and the transformer, eliminate the influence of high temperature on the installation stability of the induction coil, thereby improving the reliability of the heat treatment process and its product quality, realizing the interchangeability and universality of different types of quenching machines, and reducing the enterprise cost.

[0004] The present utility model adopts the following technical solutions to achieve the above purposes. A quenching machine inductor cooling integrated block includes two symmetric integrated block bodies. A main pipeline is arranged inside the inner side of the integrated block body. A main pipeline water inlet is arranged at the upper end of the main pipeline, and a main pipeline water outlet is arranged at the lower end. A branch pipeline is arranged on the main pipeline between the main pipeline water inlet and the main pipeline water outlet facing the outer side direction of the integrated block body. A branch pipeline water outlet is arranged at the outer end of the branch pipeline. The branch pipelines are all located between the installation screw holes or the installation counterbores.

[0005] Furthermore, internal threads are arranged at the main pipeline water inlet, the main pipeline water outlet and the branch pipeline water outlet.

[0006] Furthermore, the branch pipeline is perpendicularly and cross - connected with the main pipeline.

[0007] Furthermore, the installation counterbore is a stepped hole.

[0008] By arranging branch pipelines inside the integrated block body to distribute the cooling water flow, the present utility model can take away a large amount of heat generated by magnetic field induction during quenching. Its structure is simple, the internal pipeline distribution is reasonable and compact, the cooling effect is very obvious, it can be compatible with the use of different inductor mounting hole pitches, reduce the enterprise cost, ensure the reliability of the heat treatment process, and greatly improve the quality of heat - treated products.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The following further describes the present utility model in conjunction with the drawings and embodiments. Refer to Figure 3 and Figure 4, A quenching machine inductor cooling integrated block, comprising two symmetrical integrated block bodies 1. A main pipeline 2 is arranged inside the inner side edges of the integrated block body 1. A main pipe water inlet 4 is arranged at the upper end of the main pipeline 2, and a main pipe water outlet 5 is arranged at the lower end. Between the main pipe water inlet 4 and the main pipe water outlet 5, the main pipeline 2 is arranged facing the outer side direction of the integrated block body 1 with branch pipelines 6, and the branch pipelines 6 are perpendicularly and cross - connected to the main pipeline 2. The outer ends of the branch pipelines 6 are provided with branch pipe water outlets 3, and the branch pipelines 6 are all located between the installation screw holes 7 or the stepped installation counter - bores 8. The main pipe water inlet 4, the main pipe water outlet 5 and the branch pipe water outlets 3 are all provided with internal threads.

[0015] Embodiment: The following lists a preferred example of the present utility model. Two integrated block bodies 1 of the same size are made of copper plate material to replace the connecting plate 01 in the prior art. Its thickness is 30 mm. According to the distribution of the connecting screws on the quenching machine, four upper and lower installation counter - bores 8 are drilled respectively, and installation screw holes 7 are machined according to the different connection hole distances of the inductor. 9 - mm counter - bores are drilled and tapped with M10 internal threads at the upper and lower ends inside the two symmetrical integrated block bodies 1 to make the main pipe water inlet 4 and the main pipe water outlet 5. Then, 6 - mm through - holes are drilled in the 9 - mm counter - bores as the main pipeline 2 to connect the upper and lower main pipe water inlets 4 and main pipe water outlets 5. 9 - mm counter - bores are drilled on the outer side of the integrated block body 1 and tapped to make internal threads for the branch pipe water outlets 3, and 6 - mm branch pipelines 6 are drilled in the counter - bores to make the inner ends of the branch pipelines 6 communicate with the main pipeline 2. The main pipeline 2 and the branch pipelines 6 should avoid the installation counter - bores 8 and the installation screw holes 7, that is, be located at the gaps between the installation counter - bores 8 and the installation screw holes 7. After the integrated block body 1 is processed, it is installed on the outer wall of the rectifier transformer, and then the electromagnetic induction coil 04 is installed on the integrated block body 1 with bolts. Water pipe joints are installed at the main pipe water inlet 4, the main pipe water outlet 5 and the branch pipe water outlets 3 respectively and connected to the cooling water pipes. After water is passed through, the water flows away towards the lower end and the side of the integrated block body 1 respectively, taking away a large amount of heat generated during quenching.

[0016] The structure of the present utility model is reasonable, and it can be compatible with the connection and installation of quenching machine inductors from different manufacturers on the market. The heat dissipation and cooling effect is remarkable. Compared with the previous connecting plate, the cooling efficiency is increased by more than three times, avoiding the damage of the quenching machine body caused by the burning of the screw and the damage of the threaded hole. At the same time, for quenching parts of different sizes, specifications and shapes, the inductor matching the parts can be quickly replaced, greatly extending the service life of the quenching machine, and is worthy of popularization and application.
