Description

Technical Field

[0001] This invention belongs to the field of amorphous alloy technology, and more specifically, relates to an amorphous alloy strip shearing device. Background Technology

[0002] Amorphous alloys are solidified by ultra-rapid cooling. During solidification, the atoms do not have enough time to arrange themselves in an orderly crystallization pattern, resulting in a solid alloy with a long-range disordered structure. The molecules (or atoms, ions) that make up the alloy do not exhibit a spatially regular periodicity, and there are no grains or grain boundaries present in crystalline alloys. Amorphous alloys are also known as glassy alloys. Due to their disordered atomic arrangement and lack of crystalline structure, they possess high strength, high hardness, and corrosion resistance, as well as excellent soft magnetic properties, insensitivity to stress, high resistivity, low eddy current loss, and no magnetocrystalline anisotropy. Furthermore, components made from soft magnetic materials such as amorphous alloys have advantages such as small size, high output power, high efficiency, and good temperature stability. Therefore, they are widely used in high-frequency transformers, high-power iron cores, sensors, chokes, current transformers, filter current sensor cores, Hall current sensor cores, and cores for various welding machines and power supplies.

[0061] Please see Figures 1 to 5The amorphous alloy strip shearing device provided by the present invention will now be described. An amorphous alloy strip shearing device includes a worktable 1, a support roller 2, a low-position limiting roller 3, multiple guide rollers 4, multiple extrusion rollers 5, and a cutting blade 6 arranged sequentially along the length of the worktable 1. The worktable 1 has a hollow structure, and its upper end is provided with a connecting hole 11 communicating with the hollow structure. The worktable 1 is provided with a cutting surface 12 for laying the amorphous alloy strip. The support roller 2 is located at one end of the worktable 1. The amorphous alloy strip is wound around the support roller 2. The low-position limiting roller 3 corresponds to the connecting hole 11, and its lower end is located inside the connecting hole 11. The amorphous alloy strip is wound around the low-position limiting roller 3. The lower side of the limiting roller 3; the height of multiple guide rollers 4 gradually increases from the support roller 2 toward the lower limiting roller 3; the height of the guide roller 4 near the lower limiting roller 3 is higher than the lower end of the lower limiting roller 3, and the height of the guide roller 4 away from the lower limiting roller 3 is flush with the height of the cutting surface 12; the extrusion roller 5 is installed on the cutting surface 12 and has the freedom to move downward; the cutting blade 6 is located above the cutting surface 12, and the cutting blade 6 includes a cutting disc 61 and two tightening roller mechanisms 62 located on both sides of the cutting disc 61; both tightening roller mechanisms 62 have the freedom to rotate toward the cutting disc 61.

[0062] The amorphous alloy strip shearing device provided by this invention, compared with the prior art, involves winding the amorphous alloy strip onto a support roller 2. One end of the amorphous alloy first passes over a low-position limiting roller 3. With the lower end of the low-position limiting roller 3 located within a connecting hole 11, the amorphous alloy moves upwards. After passing through multiple guide rollers 4 with gradually changing heights, it enters the shearing surface. This upward movement from an inclined surface to a flat surface results in higher flatness of the portion of the amorphous alloy strip within the shearing surface, leading to more accurate cutting. Multiple extrusion rollers 5 move downwards to contact the surface of the amorphous alloy strip. The distance between the extrusion rollers 5 and the shearing surface is equal to the thickness of the amorphous alloy strip. The subsequent cutting of the amorphous alloy strip is more accurate. Then, the cutting blade 6 is used to cut the amorphous alloy strip. When the cutting disc 61 is used to cut the amorphous alloy strip, both tensioning roller mechanisms 62 move towards the cutting disc 61, so that both sides of the cut edge of the amorphous alloy strip tend to move towards the cut edge, thereby reducing or even eliminating the tearing phenomenon at the shearing edge. In this way, with the help of the low-position limiting roller 3, guide roller 4 and extrusion roller 5, the amorphous alloy strip is placed flat on the cutting surface 12 and pressed tightly on the cutting surface 12, making the cutting more accurate. At the same time, under the action of the two tensioning roller mechanisms 62, the tearing phenomenon at the shearing edge is reduced or even eliminated, meeting the usage requirements.

[0063] A transition roller 14 is provided between the support roller 2 and the low-position limiting roller 3 to prevent wrinkles or other phenomena from occurring when the amorphous alloy strip moves from the support roller 2 to the low-position limiting roller 3.

[0064] Please see Figure 4 and Figure 5 As a specific embodiment of the amorphous alloy strip shearing device provided by the present invention, the tensioning roller mechanism 62 includes an extrusion block 63, a first mounting groove 64, first tensioning rollers 65, and a first driving assembly; the extrusion block 63 is located on one side of the cutting disc 61; and the extrusion block 63 is provided with a central hole, through which the rotating shaft of the cutting disc 61 passes and is rotatably connected to the extrusion block 63; the first mounting groove 64 is opened at the lower end of the extrusion block 63; the first mounting groove 64 is a rectangular groove; the number of first tensioning rollers 65 is... Multiple first tension rollers 65 are rotatably connected within the first mounting groove 64; multiple first tension rollers 65 are arranged in a rectangular array; the axial direction of the first tension rollers 65 is the same as the length direction of the amorphous alloy strip; the radial dimension of the first tension rollers 65 is greater than the depth of the first mounting groove 64; a first drive assembly is mounted on the extrusion block 63; the first drive assembly is connected to the multiple first tension rollers 65 for driving the multiple first tension rollers 65 to rotate toward the blade disk 61; the blade disk 61 is subjected to inward extrusion force at the cut point between it and the amorphous alloy strip.

[0065] Two first drive components are activated to control multiple first tensioning rollers 65 to rotate in the first mounting groove 64, so that the lower ends of the first tensioning rollers 65 on both sides of the cutting disc 61 contact the amorphous alloy strip and rotate towards the cutting disc 61; therefore, when the cutting disc 61 cuts the amorphous alloy strip, under the action of the first tensioning rollers 65 on both sides, the amorphous alloy strip on both sides of the cut moves towards the cut, reducing tearing at the cut. The first drive components are a drive motor and gear chain structure.

The first mounting groove 64 is located on the side of the extrusion block 63 near the blade 61, and the second mounting groove 7 is located on the side of the extrusion block 63 away from the blade 61. The second mounting groove 7 is a rectangular groove. There are multiple second tensioning rollers 71, which are rotatably connected in the second mounting groove 7. The multiple second tensioning rollers 71 are arranged in a rectangular array. The axial direction of the second tensioning rollers 71 is perpendicular to the length direction of the amorphous alloy strip. The radial dimension of the second tensioning rollers 71 is greater than the depth of the second mounting groove 7. The second driving assembly is mounted on the extrusion block 63. The second driving assembly is connected to the multiple second tensioning rollers 71 for driving the multiple second tensioning rollers 71 to rotate parallel to the blade 61. The second tensioning rollers 71 act on the amorphous alloy strip from top to bottom.

[0067] The second pressing roller 71 makes the extrusion block 63 press down on the amorphous alloy strip, so that the amorphous alloy strip is in closer and flatter contact with the cutting surface 12, so that the cutting disc 61 can cut the amorphous alloy strip more accurately.

[0068] Please see Figure 1 As a specific embodiment of the amorphous alloy strip shearing device provided by the present invention, the amorphous alloy strip shearing device further includes a mounting frame 8, a rotating support frame, and a third drive assembly. The mounting frame 8 is fixedly installed on the upper end of the workbench 1 and is located above the cutting surface 12. There is an installation space between the mounting frame 8 and the cutting surface 12. The rotating connecting frame 81 is located in the installation space and its upper end is connected to the mounting frame 8. The lower end of the rotating connecting frame 81 is provided with a third mounting groove 82. The third drive assembly is fixedly connected to the rotating connecting frame 81. Multiple extrusion rollers 5 are located in the installation space. The cutting disc 61 and two tightening roller mechanisms 62 are installed in the third mounting groove 82. The third drive assembly is connected to the cutting disc 61 for driving the cutting disc 61 to rotate.

[0069] The cutting disc 61 and the two tensioning roller mechanisms 62 are both installed in the third mounting groove 82, and the two tensioning roller mechanisms 62 are installed on both sides of the cutting disc 61.

[0070] Furthermore, a mounting bracket 8 and a rotating support bracket are provided. The mounting bracket 8 is an inverted U-shaped structure. The upper end of the rotating support bracket is mounted on the mounting bracket 8, and the third mounting groove 82 is opened at the lower end of the rotating support bracket.

[0072] Two sets of extrusion rollers 5 are set up and installed on both sides of the cutting blade 6, so that the amorphous alloy strip located on both sides of the cutting blade 6 is subjected to uniform force and the extrusion effect is better.

[0073] Before cutting, the fourth drive assembly is activated to control the rotating support frame to rotate upward, so that the blade 61 is away from the amorphous alloy strip. One end of the amorphous alloy strip needs to be pulled through the low-position limit roller 3, guide roller 4, extrusion roller 5, etc., and laid on the cutting surface 12. Then the fourth drive assembly is activated to control the rotating support frame to rotate downward, so that the blade 61 contacts the amorphous alloy strip to achieve cutting.

[0074] Please see Figure 1 As a specific embodiment of the amorphous alloy strip shearing device provided by the present invention, the extrusion roller 5 includes a mounting base 51, a roller 53, and a lifter. There are two mounting bases 51, which are located on both sides of the worktable 1. Each mounting base 51 is provided with a mounting hole 52, a bearing seat, and a bearing. The bearing seat is installed in the mounting hole 52, and the bearing is installed in the bearing seat. The mounting hole 52 is a vertical elongated hole.

[0075] When it is necessary to use the extrusion roller 5 to press onto the amorphous alloy strip, the drive bearing seat and roller 53 are activated to move up and down within the vertically elongated mounting hole 52, thereby pressing the lower end of the roller 53 onto the amorphous alloy strip.

Multiple guide rollers 4 are installed on the bearing plate 13 and are arranged side by side. The guide roller 4 includes a base 41 and a roller body 42. There are two bases 41, which are fixedly installed at both ends of the bearing plate 13. The roller body 42 is installed between the two bases 41. The two ends of the roller body 42 are rotatably connected to the two bases 41 respectively. The lower end of the guide roller 4 located at the end of the bearing plate 13 away from the support roller 2 is higher than the upper end of the adjacent guide roller 4 and has an installation gap 44, which is equal to the thickness of the amorphous alloy strip.

The guide rollers 4 located away from the support roller 2 are staggered with the adjacent guide rollers 4, and there is an installation gap 44 between them, so that the amorphous alloy strip passes through a region accurately laid on the cutting surface 12 before being guided to the cutting surface 12. A clearance slope 43 is provided at the intersection of the cutting surface 12 and the connecting hole 11, so that the amorphous alloy strip will not come into contact with the edges when it passes through the guide rollers 4 and enters the cutting surface 12.

[0078] Please see Figure 1 and Figure 3 As a specific embodiment of the amorphous alloy strip shearing device provided by the present invention, the amorphous alloy strip shearing device further includes a collecting mechanism 9, which is located at the other end of the workbench 1. The collecting mechanism 9 is used to collect the sheared amorphous alloy strip. The collecting mechanism 9 includes a guide roller group 91, a winding roller 93, and a tensioning roller 95. There are two guide roller groups 91, which are arranged side by side with intervals. A moving channel for the sheared strip is formed between the two guide roller groups 91. The other end of the workbench 1 is provided with a first mounting plane 92, which is lower than the cutting surface 12.

[0079] After being cut, the amorphous alloy strip passes through multiple guide rollers and is confined within the annular limiting grooves of the multiple guide rollers. At this moment, the cut amorphous alloy strip is still well laid on the cutting surface 12, preventing it from shaking or lifting due to external forces caused by the need to collect the cut amorphous alloy strip, thus avoiding affecting the accurate operation of the cutting blade 6 on the cutting surface 12.

[0080] After being cut, the amorphous alloy strip is first wrapped around the tension roller 95 and then wound around the collection roller to ensure that the cut amorphous alloy strip is collected more tightly and neatly.

The amorphous alloy strip shearing device includes multiple compaction cutting mechanisms, so that the amorphous alloy strip can be cut into multiple segments at the same time when it is being cut, resulting in higher work efficiency.

[0083] Please see Figure 1 As a specific embodiment of the amorphous alloy strip shearing device provided by the present invention, the amorphous alloy strip shearing device further includes connecting holes and a vacuum generator. There are multiple connecting holes, which are opened on the cutting surface 12. The multiple connecting holes are arranged in a rectangular array. All the multiple connecting holes are connected to the hollow structure. The vacuum generator is installed inside the hollow structure. The vacuum generator is connected to the multiple connecting holes.

[0084] After the amorphous alloy strip is laid on the cutting surface 12, the vacuum generator is started, and the amorphous alloy strip is subjected to negative pressure through multiple connecting holes, so that the amorphous alloy strip is laid more evenly on the cutting surface 12.

[0085] The worktable 1 is designed as a hollow structure, and the vacuum generator is installed inside the hollow structure. Multiple connecting holes are arranged in a rectangular array, which ensures that the amorphous alloy strip is subjected to relatively uniform stress.

[0086] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
