Description

Technical Field

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

[0002] Amorphous alloy strip refers to amorphous alloy thin strip material with elements such as iron, cobalt, silicon, and boron as the main components. It is usually prepared by rapid solidification process such as single-roll quenching. It has outstanding properties such as high magnetic permeability, low iron loss, high strength, and excellent corrosion resistance. It is a key functional material in the fields of transformer cores and high-frequency electromagnetic components.

[0003] The processing of amorphous alloy strips typically involves using a shearing machine to cut continuous amorphous alloy strips into two typical specifications: long strips (length greater than width) and short wide strips (width greater than length). In related technologies, after shearing, these strips are usually laid flat and stacked for rapid stacking. However, this flat stacking method requires an additional bending process to shape the strips into a U-shape (e.g., to meet the requirements of transformer core processing). This not only increases the complexity of the production process and reduces efficiency, but also because amorphous alloy strips are brittle, repeated transfers and handling can easily lead to edge damage, warping, and performance degradation. Summary of the Invention

[0004] The purpose of this invention is to provide an amorphous alloy strip shearing device that can quickly shear two specifications of strip segments (long strip segments and short and wide strip segments) and stack them in a U-shape without the need for additional bending processes in the subsequent process.

[0020] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] The amorphous alloy strip shearing device according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0022] The amorphous alloy strip shearing device of this invention, as shown in the embodiments of the present invention. Figure 1 , Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, it may include: a strip shearing machine 1, a linear drive assembly 2, a winding machine 4, a U-shaped lifting stacking platform 6, and a first motor 7.

[0023] The strip shearing machine 1 is configured to cut amorphous alloy strips into long strips or short and wide strips. The linear drive assembly 2 is equipped with two negative pressure adsorption devices 3, which are configured to drive the negative pressure adsorption devices 3 to move in the horizontal and vertical directions.

[0024] The negative pressure adsorption device 3 includes a chamber 31 and negative pressure adsorption plates 32. The chamber 31 is mounted on the linear drive assembly 2, and the negative pressure adsorption plates 32 are hinged to the chamber 31 via torsion spring hinges 33. The two negative pressure adsorption plates 32 have a first working state and a second working state, such as... Figure 15and Figure 16 As shown, in the first working state, the two negative pressure adsorption plates 32 are arranged in a straight line to adsorb and adhere or detach long strip segments. In the second working state, the two negative pressure adsorption plates 32 are arranged parallel and spaced apart to adsorb and adhere or detach short and wide segments. A cable reel 4 is mounted on the linear drive assembly 2. The negative pressure adsorption plates 32 are connected to the cable reel 4 via connecting ropes 5. When the cable reel 4 is configured to wind up the connecting rope 5, it drives the negative pressure adsorption plates 32 to rotate forward against the elastic force of the torsion spring hinge 33 to the first working state. When unwinding the connecting rope 5, the torsion spring hinge 33's restoring elastic force drives the negative pressure adsorption plates 32 to rotate in the opposite direction to the second working state.

[0025] The U-shaped lifting stacking platform 6 is used to stack long strips or short strips that have detached from the negative pressure adsorption plate 32. The drive end of the first motor 7 is connected to the U-shaped lifting stacking platform 6. The first motor 7 is configured to drive the U-shaped lifting stacking platform 6 to rotate, so that the U-shaped lifting stacking platform 6 switches between a first preset angle position for stacking long strips and a second preset angle position for stacking short strips.

[0026] It should be noted that the strip shearing machine 1 can cut two typical specifications of strip segments: one is a long strip segment (i.e., a long strip segment whose length is greater than its width) and the other is a short and wide strip segment (i.e., a short and wide strip segment whose width is greater than its length). The machine adapts to these two types of strip segments by switching between the two states.

[0027] It is understood that the U-shaped lifting stacking platform 6 described in this embodiment can stack strip segments into a U-shape when stacking them, eliminating the need for subsequent bending processes. The first motor 7 controls the rotation of the U-shaped lifting stacking platform 6 (for example, a 90° rotation) to accommodate two different specifications of strip segments. That is, when the two adsorption plates 32 switch between the first and second working states, the first motor 7 controls the U-shaped lifting stacking platform 6 to rotate accordingly.

[0028] Furthermore, such as Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, a second lead screw driver 34 is provided inside the chamber 31. The adsorption plate 32 is connected to the second lead screw driver 34 through a torsion spring hinge 33. The second lead screw driver 34 is configured to drive the torsion spring hinge 33 to move horizontally inside the chamber 31.

[0029] It is understood that the second lead screw driver 34 described in this embodiment drives the corresponding adsorption plate 32 to move horizontally in the second working state by adjusting the position of the torsion spring hinge 33 within the chamber 31. By adjusting the distance between the two adsorption plates 32 to accommodate short and wide bands of different lengths, the optimal adsorption position of the two adsorption plates 32 when moving the short and wide bands is to adsorb the edge of the short and wide bands.

[0030] The torsion spring hinge 33 may include: a first mounting part 331, a second mounting part 332, a shaft 333, and a torsion spring 334. The first mounting part 331 is fixedly mounted on the second lead screw driver 34. The second mounting part 332 is connected to the upper surface of the adsorption plate 32. The shaft 333 passes through the hinge hole of the first mounting part 331 and the second mounting part 332. The torsion spring 334 is sleeved on the shaft 333. The first free end of the torsion spring 334 abuts against the side wall of the first mounting part 331, and the second free end of the torsion spring 334 abuts against the side wall of the second mounting part 332. The torsion spring 334 is configured to provide a reset torque to the adsorption plate 32 to rotate around the shaft 333.

[0031] It is understood that the torsion spring hinge 33 described in this embodiment is in an open / closed state under external force in the first working state, and in a closed state under no external force in the second working state.

[0032] To clearly illustrate the previous embodiment, in one embodiment of the present invention, as follows: Figure 2 and Figure 3 As shown, the linear drive assembly 2 may include: a first lead screw driver 21, a first electric telescopic rod 22, and a mounting plate 23. The first electric telescopic rod 22 is mounted on the first lead screw driver 21, and the mounting plate 23 is mounted on the telescopic end of the first electric telescopic rod 22. Two negative pressure adsorption devices 3 are respectively mounted on the mounting plate 23 (the chamber 31 is fixedly mounted on the mounting plate 23). The first electric telescopic rod 22 is used to drive the negative pressure adsorption device 3 to move vertically, and the first lead screw driver 21 is used to drive the negative pressure adsorption device 3 to move horizontally.

[0033] Specifically, the first lead screw driver 21 drives the negative pressure adsorption device 3 to adsorb and pull the amorphous alloy strip over the strip shearing machine 1. The strip shearing machine 1 cuts the amorphous alloy strip to obtain amorphous alloy strip segments. The U-shaped lifting stacking platform 6 rises and abuts against the lower part of the amorphous alloy strip segments. The negative pressure adsorption device 3 no longer provides adsorption force (limiting) to the amorphous alloy strip segments, and the amorphous alloy strip segments are stacked on the U-shaped lifting stacking platform 6 by their own gravity. Repeating the above operation, multiple amorphous alloy strip segments can be stacked in a U-shape.

[0034] When dealing with long strips, the winding device 4 rewinds the two connecting ropes 5, putting the two adsorption plates 32 into a first working state (in this state, the torsion spring hinges 33 are rotated by external force). In this state, it can be used to adsorb and pull the amorphous alloy strip body, and can also adsorb the short side of the long strip. When dealing with short and wide strips, the winding device 4 unwinds the two connecting ropes 5, putting the two adsorption plates 32 into a second working state (in this state, the torsion spring hinges 33 reset due to the lack of external force, and at the same time, they drive the corresponding adsorption plates 32 to rotate). In this state, it can adsorb the two short sides of the short and wide strip.

[0035] By quickly adjusting the positions of the adsorption plate 32 and the U-shaped lifting stacking platform 6, it is possible to stack both types of strip segments, which is highly applicable. After stacking long strip segments, multiple sets of short and wide strip segments can be directly stacked on the stacked long strip segments to improve the continuity of shearing.

[0036] In one embodiment of the present invention, such as Figure 1 , Figure 6 and Figure 12 As shown, the winding device 4 may include: a mounting chamber 41, a third motor 42, a drive wheel 43, two driven wheels 44, and two winding rollers 45. The two driven wheels 44, two connecting ropes 5, two winding rollers 45, and two negative pressure adsorption devices 3 correspond one-to-one. The mounting chamber 41 is mounted on the mounting plate 23, the third motor 42 is mounted inside the mounting chamber 41, the drive wheel 43 is mounted on the drive end of the third motor 42, the two winding rollers 45 are rotatably mounted inside the mounting chamber 41, the driven wheels 44 are mounted on the winding rollers 45, and the driven wheels 44 mesh with the drive wheel 43. The negative pressure adsorption devices 3 are connected to the winding rollers 45 through the connecting ropes 5.

[0037] It is understood that the third motor 42 described in this embodiment can simultaneously drive two driven wheels 44 to rotate via the driving wheel 43. The driven wheels 44 drive the corresponding winding rollers 45 to rotate, thereby winding and unwinding the connecting rope 5.

[0038] Furthermore, a guide ring is provided on the bin body 31, and a through hole is opened on the bin body 31. One end of the connecting rope 5 is connected to the adsorption plate 32, and the other end of the connecting rope 5 passes through the guide ring and the through hole in sequence and enters the bin body 31 to connect with the winding roller 45.

[0039] In one embodiment of the present invention, such as Figure 1 and Figure 12 As shown, the U-shaped lifting stacking platform 6 may include: a fixed plate 61, a first hydraulic telescopic device 62, and a receiving platform 63. The first hydraulic telescopic device 62 is mounted on the fixed plate 61, which is mounted on the drive end of the first motor 7. The receiving platform 63 is mounted on the drive end of the first hydraulic telescopic device 62.

[0040] It is understood that the first hydraulic telescopic device 62 described in this embodiment can control the receiving platform 63 to move vertically so that the receiving platform 63 can contact or separate from the amorphous alloy strip. The receiving platform 63 is vertically elongated and has a rounded top.

[0041] In one embodiment of the present invention, such as Figure 11 and Figure 14 As shown, it may also include: a second motor 8, a second hydraulic telescopic device 9 on the second motor 8, a pressure plate 10 on the second hydraulic telescopic device 9, the pressure plate 10 being positioned above the amorphous alloy strip, the second hydraulic telescopic device 9 being configured to drive the pressure plate 10 to abut against the upper part of the amorphous alloy strip after the U-shaped lifting stacking platform 6 abuts against the bottom of the amorphous alloy strip segment, so that after the amorphous alloy strip segment loses the limitation of the negative pressure adsorption device 3, it is stacked on the U-shaped lifting stacking platform 6 by its own gravity.

[0042] It is understood that, in this embodiment, the second hydraulic telescopic device 9 controls the pressure plate 10 to move vertically downwards. After the pressure plate 10 and the U-shaped lifting stacking platform 6 clamp the amorphous alloy strip segment in the middle, the negative pressure adsorption device 3 no longer provides adsorption force (limiting) to the amorphous alloy strip segment. The two ends of the amorphous alloy strip segment are stacked on the U-shaped lifting stacking platform 6 by their own gravity. By clamping and limiting the middle part of the amorphous alloy strip segment, the amorphous alloy strip segment can be stacked more neatly.

[0043] It should be noted that the U-shaped lifting stacking platform 6 is normally suitable for long strips. When cutting short and wide strips, the U-shaped lifting stacking platform 6 can be rotated 90° by the first motor 7 to adapt to the short and wide strips. When the angle of the U-shaped lifting stacking platform 6 changes, the second motor 8 needs to drive the second hydraulic telescopic device 9 to rotate synchronously.

[0044] In one embodiment of the present invention, such as Figure 11 , Figure 12 and Figure 13 As shown, it may also include: a rolling combing fixing mechanism 11. The rolling combing fixing mechanism 11 may include: a third lead screw driver 111, a moving frame 112, two electric push rods 113 and two pressure rollers 114. The two electric push rods 113 and the two pressure rollers 114 correspond one-to-one. The moving frame 112 is mounted on the third lead screw driver 111, the two electric push rods 113 are symmetrically mounted on the moving frame 112, and the pressure rollers 114 are mounted on the telescopic ends of the electric push rods 113. The third lead screw driver 111 is used to drive the moving frame 112 to move vertically.

[0045] Specifically, after the two ends of the amorphous alloy strip are stacked on the U-shaped lifting stacking platform 6 by their own gravity, the electric push rod 113 controls the horizontal movement of the pressure roller 114 so that the pressure roller 114 abuts against the amorphous alloy strip. The third lead screw driver 111 drives the moving frame 112 to move vertically, causing the pressure roller 114 to roll on the amorphous alloy strip, flattening the amorphous alloy strip. When the U-shaped lifting stacking platform 6 rises, the two pressure rollers 114 can clamp the amorphous alloy strip near the lower end, so that the stacked amorphous alloy strip is stable on the U-shaped lifting stacking platform 6, ensuring the neatness of the stacking.

[0046] In one embodiment of the present invention, such as Figure 11 and Figure 12 As shown, it also includes: a base 12, a fourth lead screw driver 13 and a frame 14, wherein the fourth lead screw driver 13 is disposed on the base 12, the frame 14 is disposed on the fourth lead screw driver 13, the fourth lead screw driver 13 is used to drive the frame 14 to move horizontally, the first motor 7 and the second motor 8 are respectively disposed on the frame 14, and the first motor 7 is disposed below the second motor 8.

[0047] Furthermore, a first rotating shaft 15 and a second rotating shaft 16 are rotatably mounted on the frame 14. A first motor 7 is connected to the first rotating shaft 15 through a first bevel gear set 17. A U-shaped lifting stacking platform 6 is located at the top of the first rotating shaft 15. A second motor 8 is connected to the second rotating shaft 16 through a second bevel gear set 18. A second hydraulic telescopic device 9 is located at the bottom of the second rotating shaft 16.

[0048] In one embodiment of the present invention, such as Figure 9 and Figure 10 As shown, the strip shearing machine 1 includes: a shearing blade 101, a blade holder 102, a receiving platform 103, a third hydraulic telescopic device 104, and a mounting frame 105. The mounting frame 105 is mounted on the receiving platform 103, the third hydraulic telescopic device 104 is mounted on the mounting frame 105, the shearing blade 101 is mounted on the telescopic end of the third hydraulic telescopic device 104, and the blade holder 102 is mounted on the receiving platform 103, and the blade holder 102 is located directly below the shearing blade 101.

[0049] It should be noted that the lead screw drive (first lead screw drive 21, second lead screw drive 34, third lead screw drive 111 and fourth lead screw drive 13) described in the above embodiments may include: a motor, a ball screw, a ball slider and a slider limiter. The ball screw is disposed on the drive end of the motor, the ball slider is disposed on the ball screw, the ball slider drives the components connected to the lead screw drive to move, and the ball slider and the slider limiter are slidably connected.

[0050] Depending on the installation location, the type of slider limit component in a lead screw drive varies (e.g., a sliding rod connected to the ball slider, a limit slider connected to the ball slider, etc.). Depending on the installation requirements, a drive chamber may also be included, in which the motor, ball screw, ball slider, and slider limit component are all housed.

[0051] It should be noted that the motors described in the above embodiments (e.g., the first motor 7, the second motor 8, the third motor 42, the motor in the lead screw driver, etc.) are equipped with brakes, which can make the motor stop running quickly. A gearbox is provided on the drive end of the motor, and the drive end of the motor is connected to the input end of the gearbox. The output end of the gearbox constitutes the drive end of the motor, and the speed of the motor output is adjusted by the gearbox.

[0052] In summary, the amorphous alloy strip shearing device of this invention can quickly shear and stack two specifications of strip segments (long strip segments and short and wide strip segments) in a U-shape without the need for additional bending processes in the subsequent process.
