Description

Technical Field

[0001] This utility model relates to the field of metal powder preparation technology, and in particular to a coil positioning device for a gas atomizing furnace. Background Technology

[0002] Gas atomizing furnaces are commonly used equipment for preparing metal powders. The coil is one of the core components of a gas atomizing furnace, primarily used for induction heating of metallic materials. The coil is typically installed around the atomizing chamber or melting area, forming a uniform magnetic field. Alternating current passes through the coil, generating an alternating magnetic field that induces eddy currents and hysteresis effects within the metal, rapidly melting the metal rod above it. The liquid metal is then broken into small particles by airflow, and finally cooled to form powder. As can be seen from the above process, the precise positioning of the coil within the gas atomizing furnace is crucial. If the metal rod, coil, and atomizer generating the airflow are not aligned on the same axis, both the efficiency and quality of metal powder preparation will be severely affected.

[0003] Currently, coils are mainly installed using manual winding. However, when faced with large-scale, high-precision production tasks, the positioning accuracy of manual winding is difficult to guarantee. After assembly, coils often become misaligned with the atomizer's center and have inconsistent heights, leading to situations where the coil contacts the rod during atomization, causing power outages. This necessitates repeated adjustments and verifications, impacting production efficiency. Furthermore, manual winding is inefficient and difficult to adapt to the requirements of automated atomization production lines.

[0004] In view of this, based on years of experience in production and design in this and related fields, the inventor has designed a coil positioning device for a gas atomizing furnace through repeated experiments, in order to solve the problems existing in the prior art. Utility Model Content

[0033] like Figures 1 to 4 As shown, this utility model proposes a coil positioning device 100 for a gas atomizing furnace. The gas atomizing furnace has a flange 200 for installing the coil. The coil positioning device 100 is installed on the flange 200. The coil positioning device 100 includes a coil 10, a lower positioning block 20, a positioning post 30, and an upper positioning block 40. The lower positioning block 20 is inserted into the center hole of the flange 200. One end of the positioning post 30 vertically penetrates the lower positioning block 20 and is fixedly connected to the lower positioning block 20. The other end of the positioning post 30 vertically penetrates the upper positioning block 40 and is threadedly connected to the upper positioning block 40. The coil 10 is sleeved on the positioning post 30. One end of the coil 10 abuts against the lower positioning block 20, and the other end of the coil 10 abuts against the upper positioning block 40.

[0034] The coil positioning device 100 for a gas atomizing furnace proposed in this utility model installs the coil 10 on the flange 200 through the lower positioning block 20 and the positioning column 30, which can accurately position the horizontal position of the coil 10. The height of the upper positioning block 40 is adjusted by the threaded engagement between the upper positioning block 40 and the positioning column 30, and the vertical position of the coil 10 is precisely adjusted by the contact between the upper positioning block 40 and the coil 10. The coil positioning device 100 for a gas atomizing furnace proposed in this utility model can quickly determine the horizontal and vertical positions of the coil 10, avoiding repeated adjustments during coil 10 installation, effectively improving the installation efficiency of the coil 10, and reducing production and manufacturing costs.

[0035] In one optional embodiment of this invention, the coil 10 gradually expands in diameter along the direction from the lower positioning block 20 to the upper positioning block 40, and the upper positioning block 40 is in the shape of a gradually expanding frustum. With this structure, after the conical surface of the upper positioning block 40 contacts the opening at the upper end of the coil 10, the outer conical surface of the upper positioning block 40 coincides with the inner conical surface of the coil 10, and the coil 10 is clamped by the upper positioning block 40, effectively preventing the coil 10 from moving and further ensuring the precise positioning of the coil 10.

[0036] In an optional embodiment of this utility model, the positioning pin 30 is coaxially arranged with the flange 200. The coil 10 is fastened by the upper positioning block 40, and after the lower positioning block 20 is assembled into the center hole of the flange 200, the center line of the coil 10 coincides with the center line of the gas atomizing furnace, thereby completing the overall positioning of the coil 10.

[0037] In an optional embodiment of this utility model, the upper positioning block 40 has a radially through hole 41, and a rotating pin (not shown in the figure) passes through the through hole 41, with both ends of the rotating pin protruding out of the through hole 41. With the above structure, when it is necessary to rotate the upper positioning block 40, the rotating pin is inserted into the through hole 41, and the installer rotates the upper positioning block 40 by rotating the rotating pin to adjust the position of the upper positioning block 40 on the positioning post 30.

[0038] In an optional embodiment of this invention, a first limiting structure is provided between the lower positioning block 20 and the flange 200. The first limiting structure includes a first limiting boss 21 provided on the outer wall of the lower positioning block 20 and a first limiting step 210 provided on the inner wall of the flange 200. The first limiting boss 21 is aligned and engaged with the first limiting step 210. With the above structure, the lower positioning block 20 can be quickly and accurately installed in the center hole of the flange 200.

[0039] In an optional embodiment of this utility model, the coil positioning device 100 further includes a base plate 50 and a side plate 60. The base plate 50 has a mounting through hole, and a flange 200 passes through the mounting through hole. The positioning post 30, flange 200, and mounting through hole are coaxially arranged. The side plate 60 is located on one side of the positioning post 30 and is vertically connected to the base plate 50. An electrode block 70 is disposed on the side plate 60. With the above structure, after assembly, the positions of the base plate 50, flange 200, positioning post 30, and coil 10 are precisely fixed. Only the installation position of the side plate 60 needs to be changed to adjust the distance between the electrode block 70 and the coil 10, ensuring that the electrode block 70 and the coil 10 are in the optimal installation position.

[0040] In an optional embodiment of this implementation, a second limiting structure is provided between the flange 200 and the base plate 50. The second limiting structure includes a second limiting boss 220 provided on the outer edge of the flange 200 and a second limiting step 51 provided on the base plate 50. The second limiting boss 220 is aligned and engaged with the second limiting step 51. With the above structure, a quick and precise connection between the flange 200 and the base plate 50 can be achieved.

[0041] In an optional embodiment, the base plate 50 is provided with a groove (not shown in the figure), and one end of the side plate 60 is slidably disposed within the groove. The position of the side plate 60 is adjusted by moving the side plate 60 within the groove.

[0042] In an optional example, a fastening structure is also provided between the base plate 50 and the side plate 60. When the side plate 60 slides along the groove to the appropriate position, the fastening structure fixes the side plate 60 to the base plate 50.

[0043] Furthermore, the fastening structure is a bolt assembly.

[0044] In an optional example of this embodiment, the electrode block 70 can move up and down along the surface of the side plate 60. With the above structure, the height of the electrode block 70 can also move up and down with the height of the coil 10, further ensuring the precise matching between the position of the electrode block 70 and the position of the coil 10.

[0045] In one optional embodiment of this implementation, a plurality of positioning blocks 52 are provided on the bottom surface of the base plate 50 for supporting and positioning the base plate 50.

[0046] The coil positioning device 100 for a gas atomizing furnace proposed in this utility model can install the coil 10 through the lower positioning block 20, the positioning column 30 and the upper positioning block 40, and adjust the height of the coil 10 through the upper positioning block 40, so as to realize the rapid adjustment of the horizontal and vertical positions of the coil, effectively solving the problem of the gas atomizing furnace and the coil being out of sync.
