Description

TECHNICAL FIELD

[0001] The utility model belongs to amorphous magnetic ring production field, concretely relates to a cutter mechanism of amorphous magnetic ring winding machine. BACKGROUND

[0002] As a kind of high-performance magnetic element, amorphous magnetic ring is widely used, and the amorphous magnetic ring is a torus made of amorphous strip.In the process of winding amorphous magnetic ring by winding machine, when the thickness (i.e., the outer diameter) of amorphous magnetic ring reaches the requirement, the amorphous strip needs to be cut off by cutter mechanism.This cutting process directly affects the quality of amorphous magnetic ring, therefore, the stability and precision of cutter mechanism are crucial, especially when facing extremely thin amorphous strip, the precision control of cutting action is more demanding.

[0003] Currently, the moving knife part of traditional cutter mechanism of amorphous magnetic ring winding machine usually adopts simple guide structure to realize reciprocating motion.However, such structure has obvious defects: the stability of moving knife during movement is poor, and it is easy to shake or deviate.This instability leads to inaccurate movement track of cutting edge, and further causes two main problems: firstly, for extremely thin amorphous strip, it may be unable to cut off completely due to insufficient shearing force or misplacement;secondly, uneven wear of cutting edge will accelerate, shorten the service life of cutter, and affect the flatness of amorphous strip cutting surface. SUMMARY

[0004] To solve the above problems, the utility model provides a cutter mechanism of amorphous magnetic ring winding machine, which can significantly improve the movement stability of moving knife unit through structure optimization, to ensure the cutting quality of amorphous strip.

[0022] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0023] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0024] In this embodiment of the invention, the cutter mechanism of the amorphous magnetic ring winding machine is as follows: Figures 1 to 4 As shown, it includes a tool holder 1, a stationary tool 2, and a moving tool unit 3. The stationary tool 2 is fixed on the tool holder 1 and has a first cutting edge 20. The moving tool unit 3 is movably disposed on the tool holder 1 and has a second cutting edge 30 that cooperates with the first cutting edge 20. In actual use, the moving tool unit 3 is moved by an external drive mechanism (usually a cylinder). The moving tool unit 3 includes a moving tool 31, a pad 32, and a slider 33. The pad 32 is disposed between the moving tool 31 and the slider 33, so that the moving tool 31 and the slider 33 maintain a fixed distance, and two limiting grooves 34 are formed between the moving tool 31 and the slider 33. Two parallel and spaced limiting slide rails 11 are fixed on the tool holder 1. The two limiting grooves 34 slide in cooperation with the two limiting slide rails 11 respectively, so that... The moving blade unit 3 moves along the limiting slide rail 11 to bring the second cutting edge 30 closer to or further away from the first cutting edge 20. In this technical solution, the fixed distance between the moving blade 31 and the slider 33 is controlled by the precise thickness of the pad block 32, thereby precisely limiting the width of the two limiting slide grooves 34. Combined with the thickness tolerance of the upper limiting slide rail 11 of the blade holder 1, a high-precision sliding guide system is formed. This design can effectively eliminate the shaking of the moving blade unit 3 during the movement process, thereby effectively improving its motion rigidity and stability. Ultimately, it ensures that the shearing motion trajectory of the second cutting edge 30 relative to the first cutting edge 20 is accurate and consistent, enabling stable and accurate cutting. This effectively avoids problems such as the inability to cut thin amorphous strips due to shearing vibration or misalignment, and significantly improves the cutting quality.

[0025] In this embodiment, the cushion block 32, the moving blade 31, and the slider 33 are independent components, which are fixedly connected by fastening screws to form an integral body. Of course, in actual operation, the cushion block 32 and the moving blade 31 can also be set as an integral structure, or the cushion block 32 and the slider 33 can be set as an integral structure, or the moving blade 31, the cushion block 32, and the slider 33 can be set as an integral structure to reduce the number of parts.

[0026] In some embodiments, at least two first cutting edges 20 are provided on the stationary blade 2. When the stationary blade 2 is installed on the tool holder 1 in different orientations, one of the first cutting edges 20 and the second cutting edge 30 cooperate to form a cutting pair. In actual use, when one of the first cutting edges 20 becomes dull due to long-term work, there is no need to immediately replace the new tool. Only need to disassemble the stationary blade 2, reverse the direction and reinstall it, then another brand-new first cutting edge 20 can be used to continue working, effectively extending the service life of the stationary blade 2.

[0027] Furthermore, the stationary blade 2 is set as an "丄" shape. Both sides of its vertical arm 21 are provided with the first cutting edges 20, and both ends of its horizontal arm 22 are provided with mounting parts 23 for fixedly connecting with the tool holder 1. During installation, the mounting parts 23 can be fixed to the tool holder 1 by changing the direction / position, thereby swapping the orientation of the first cutting edges 20.

[0028] In another implementation scheme, second cutting edges 30 are provided at both ends of the moving blade 31. Thus, in actual use, when one of the second cutting edges 30 is worn and dull, the direction of the moving blade 31 can also be swapped, so as to replace the brand-new second cutting edge 30 and continue to use, which can also extend the service life of the moving blade 31.

[0029] See Figure 4 As shown, mounting holes 311 are provided at the parts of the moving blade 31 close to the second cutting edges 30. The mounting holes 311 are used to connect the driving mechanism. Preferably, the mounting holes 311 are set as strip-shaped holes along the width direction of the moving blade 31 to reduce the assembly accuracy requirements. Moreover, the strip-shaped holes can provide a certain assembly adjustment margin for the connection between the driving mechanism and the moving blade unit, enabling the moving blade unit to move smoothly along the predetermined track (i.e., the setting direction of the limit slide rail 11) and avoiding jamming.

[0030] In this embodiment, the limit slide rail 11 is fixed to the tool holder by fixing screws 1. In actual operation, the limit slide rail 11 can also be fixedly connected to the tool holder 1 by welding or integral molding.

[0031] For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this invention still fall within the protection scope of this invention.
