Description

Technical Field

[0002] Nanocrystalline magnetic cores have extremely high magnetic permeability, high saturation magnetic induction, low coercivity and low loss. They are suitable for EMC / EMI filter common mode inductors, high frequency transformers, inverters, current transformers and other occasions. They are also widely used in new energy fields such as solar inverters and wind power generation. In the production process, a molding device is required to process and shape the magnetic core.

When the lower pressing block rotates to and contacts the upper end of the compacting member, the lower pressing block contacts the contact ball and presses the contact ball downward, so that the positioning column moves downward to press the shaping block into the compacting groove for compaction and molding. When the lower pressing block rotates past the contact ball, the reset spring resets, so that the positioning column moves upward, and the shaping block is separated from the compacting groove. When the lower pressing block rotates to the contact ball again, the positioning column moves upward, and the shaping block is separated from the compacting groove. When the ball is in the position, the contact ball is pressed down again, so that the shaping block is pressed into the compacting groove for compaction and shaping operation, realizing reciprocating compaction and shaping operation, and the compaction effect is better.

[0025] Specifically, first put the magnetic core into the molding groove 206, then adjust the cylinder 203 to drive the connecting plate 204 and the molding template 205 to move downward, and extrude the magnetic core into shape. After molding, adjust the cylinder 203 again to move the connecting plate 204 and the molding template 205 upward, and then adjust the electric push rod 209 to extend the electric push rod 209 to drive the ejection plate 207 to eject the molded magnetic core for material collection.

[0026] Embodiment 2:

[0027] The material receiving mechanism 3 includes two transmission frames 301 and two bearing plates 302. The two transmission frames 301 are respectively fixedly arranged on the front and back of the processing table 1. A moving seat 303 is slidably connected inside the transmission frames 301. An L-shaped connecting rod 304 is fixedly connected to the top of the moving seat 303. A push plate 305 is fixedly connected between the two L-shaped connecting rods 304. The push plate 305 is slidably connected to the top of the processing table 1. The two bearing plates 302 are respectively fixedly arranged on the bottom of both sides of the processing table 1. A material receiving box 306 is fixedly arranged on the top of the bearing plates 302.

[0028] Both sides of the top of the material receiving box 306 are fixedly connected with handles 307, and the material receiving box 306 can be lifted and moved by the handles 307;

[0029] Both sides of the push plate 305 are fixedly connected with protective pads 308, and the protective pads 308 protect the magnetic core to prevent the push plate 305 from colliding with the magnetic core and causing damage to the magnetic core;

[0030] The bottom of both sides of the material receiving box 306 are fixedly connected with fixing ears 309, and the middle of the fixing ears 309 is plugged with a limiting pin 310. Both sides of the top of the carrying plate 302 are provided with limiting holes 311, and the bottom of the limiting pin 310 is plugged with the limiting hole 311. The limiting pin 310 is inserted into the fixing ears 309 and the limiting hole 311, so that the material receiving box 306 can be limited to prevent the material receiving box 306 from being easily displaced, and it is also convenient to remove the material receiving box 306;

[0031] The middle part of the transmission frame 301 is rotatably connected with a threaded screw rod 312 through a bearing, and the outer wall of the threaded screw rod 312 is threadedly connected to the middle part of the moving seat 303. The top and bottom of the transmission frame 301 are fixedly connected with a cross bar 313, and the outer wall of the cross bar 313 is slidably connected to the inside of the moving seat 303. Under the thread cooperation between the threaded screw rod 312 and the moving seat 303, the moving seat 303 drives the push plate 305 to move, and the cross bar 313 limits the moving position of the moving seat 303 to prevent the moving seat 303 from rotating with the threaded screw rod 312, so that the moving seat 303 moves horizontally;

[0032] A mounting frame 314 is fixedly connected to one side of the transmission frame 301, and a driving motor 315 is fixedly arranged inside the mounting frame 314. One end of the threaded screw 312 passes through one side of the transmission frame 301 and is fixedly connected to the transmission shaft of the driving motor 315. The driving motor 315 is started to provide power to the threaded screw 312, so that the push plate 305 moves automatically.

[0033] Specifically, first, two driving motors 315 are started simultaneously to rotate the threaded screw 312. With the threaded cooperation between the threaded screw 312 and the movable seat 303, the movable seat 303 is moved, driving the L-shaped connecting rod 304 and the push plate 305 to move. The push plate 305 pushes the ejected magnetic core to one side of the processing table 1 until the magnetic core falls into the material collection box 306 on one side, so that the processed magnetic core can be automatically collected.

[0034] When in use, first put the magnetic core into the forming groove 206, then adjust the cylinder 203 to extend the telescopic rod of the cylinder 203, drive the connecting plate 204 and the forming template 205 to move downward, and squeeze the magnetic core into shape. After forming, adjust the cylinder 203 again to move the connecting plate 204 and the forming template 205 upward, then adjust the electric push rod 209 to extend the electric push rod 209, drive the ejector plate 207 to push out the formed magnetic core, so as to collect the material;

[0035] Then, the two driving motors 315 are started at the same time to rotate the threaded screw 312. Under the cooperation of the threaded screw 312 and the moving seat 303, the moving seat 303 is moved, driving the L-shaped connecting rod 304 and the push plate 305 to move. The push plate 305 pushes the ejected magnetic core to one side of the processing table 1 until the magnetic core falls into the material receiving box 306 on one side. The two driving motors 315 are controlled to perform forward and reverse rotation at a regular time, so that the processed magnetic core can be automatically collected. Finally, the limit pin 310 is pulled out from the fixing ear 309 and the limit hole 311, so that the material receiving box 306 is out of the limit, which facilitates the removal of the material receiving box 306.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
