DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] Example 1

[0022] like Figure 1-4 As shown, the utility model provides a technical solution: a NdFeB magnet cutting device, comprising a workbench 10, a cutting opening 11 is horizontally opened on the workbench 10, a driving motor 12 is arranged below the workbench 10, a rotating shaft 13 is welded and fixed at the output end of the driving motor 12, a cutting knife 14 is fixedly sleeved on the outer wall of the rotating shaft 13, and limiting mechanisms are arranged on both sides of the upper end surface of the workbench 10, the limiting mechanisms include a cylinder 20 fixed to the upper end surface of the workbench 10, a limiting frame 21 is welded and fixed at the piston end of the cylinder 20, a plurality of grooves 22 are opened on the inner bottom wall of the limiting frame 21, and matching balls 23 are arranged in the grooves 22, an installation groove 24 is opened on the inner side wall of the limiting frame 21, and a plurality of guide rollers 25 are arranged in a horizontal array in the installation groove 24.

[0023] The drive motor 12 is provided to drive the cutting knife 14 on the rotating shaft 13 to rotate, so that the cutting knife 14 can perform a cutting operation on the NdFeB magnet to be cut. The NdFeB magnet to be cut is manually pushed to make it contact with the cutting surface of the cutting knife 14. In the cutting process, the NdFeB magnet to be cut may be offset only by manual movement. Therefore, a certain limiting operation is performed on the NdFeB magnet to be cut by the provided limiting mechanism. When in use, the end of the NdFeB magnet to be cut is first placed between the two limiting frames 21, and then the cylinder 20 is started, so that the cylinder 20 drives the limiting frame 21 to move horizontally. The reciprocating motion in the direction makes the two limit frames 21 approach or move away from each other, which can adapt to the NdFeB magnets to be cut of different widths. At this time, the bottom end of the NdFeB magnet to be cut contacts with the rolling surface of the ball 23, and the ball 23 serves as a supporting component of the NdFeB magnet to be cut. The roller surface of the guide roller 25 contacts with the outer walls of both sides of the NdFeB magnet to be cut. The NdFeB magnet to be cut is limited by the set guide roller 25, so that the NdFeB magnet to be cut is always in a straight state. This structure can move the NdFeB magnet to be cut while limiting the NdFeB magnet to be cut.

[0024] In this embodiment, both sides of the workbench 10 are provided with a slide groove 30, and an adapted slider 31 is arranged in the slide groove 30. The slider 31 is slidably connected with the slide groove 30, and the upper end surface of the slider 31 is welded and fixed to the lower end surface of the limit frame 21. In order to make the limit frame 21 move more smoothly when following the piston end of the cylinder 20, the slider 31 moves linearly in the slide groove 30, so as to ensure that the limit frame 21 is always in a straight state when moving, and the slide groove 30 is the movement track of the slider 31.

[0025] In this embodiment, the groove 22 is a hemispherical structure, and the ball 23 rolls freely in the groove 22. This can reduce the friction force when the NdFeB magnet to be cut moves.

[0026] In this embodiment, the top of the cutting blade 14 is located in the cutting opening 11, and the cutting end of the cutting blade 14 is located above the workbench 10. In this way, the cutting surface of the cutting blade 14 can contact the NdFeB magnet to be cut.

[0027] In this embodiment, a baffle 15 for shielding flying chips is welded and fixed on one side of the cutting opening 11, and one end of the baffle 15 extends above the cutting blade 14. The baffle 15 is provided to block flying chips during the cutting process to a certain extent.

[0028] In this embodiment, the roller surface of the guide roller 25 is located outside the mounting groove 24, and both ends of the guide roller 25 are rotatably connected to the inner wall of the limiting frame 21. In this way, the roller surface of the guide roller 25 contacts the side wall of the NdFeB magnet to be cut.

[0029] In this embodiment, support frames 16 are welded and fixed on both sides of the lower end surface of the workbench 10 .

[0030] Working principle: When in use, first place the end of the NdFeB magnet to be cut between the two limit frames 21, and then start the cylinder 20 so that the cylinder 20 drives the limit frame 21 to perform lateral reciprocating motion, thereby making the two limit frames 21 approach or move away from each other, and can adapt to NdFeB magnets of different widths to be cut. At this time, the bottom end of the NdFeB magnet to be cut contacts with the rolling surface of the ball 23, and the ball 23 serves as a supporting component of the NdFeB magnet to be cut, and the roller surface of the guide roller 25 contacts with the outer walls on both sides of the NdFeB magnet to be cut. The NdFeB magnet to be cut is limited by the set guide roller 25, so that the NdFeB magnet to be cut is always in a straight state. This structure can move the NdFeB magnet to be cut while limiting the NdFeB magnet to be cut.

[0031] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
