Description

Technical Field

[0001] This utility model belongs to the field of amorphous ribbon production and processing, specifically a double-sided load-bearing and winding device for amorphous ribbon. Background Technology

[0002] The core of an amorphous transformer often requires winding tens of thousands of meters of amorphous ribbon to form its shape. Existing amorphous ribbon winding devices have structures such as... Figure 1 , 2 As shown, this is a single-sided load-bearing structure, including an unwinding mechanism 1, a guide roller group 2, a tensioning mechanism 3, a control system 4, a correction mechanism 5, and a winding mechanism 6. The winding mechanism 6 includes a housing, a built-in drive motor, a support roller 8, and a hydraulic chuck 9. The output end of the built-in drive motor is connected to the support roller 8, which extends through the side wall of the housing to the external working area. The hydraulic chuck 9 is installed at the junction of the support roller 8 and the housing to provide clamping force. In practice, the iron core 18 is fitted onto the extended end of the support roller 8. The control system 4 operates to cause the amorphous strip on the unwinding mechanism 1 to pass sequentially through the guide roller group 2, the tensioning mechanism 3, and the correction mechanism 5 into the winding mechanism 6. The built-in drive motor drives the iron core 18 to rotate, thus achieving the winding and forming of the amorphous strip.

[0003] However, the aforementioned support roller 8 is located on one side of the housing, and the iron core 18 is fixedly mounted on the end of the support roller 8 away from the housing. When winding large-size amorphous strip, as the roll diameter increases, the mass of the iron core 18 and the strip assembly can exceed 500 kg. This one-sided cantilever support structure will cause the support roller 8 to bear extremely large asymmetric bending moment loads, which will eventually lead to failure and seriously restrict the continuous winding efficiency of amorphous strip and the stability of product quality. Utility Model Content

[0004] The present invention aims to provide a double-sided load-bearing winding device for amorphous strips, in order to solve the problem that the single-sided cantilever support structure in the existing winding device causes the support roller to bear extremely large asymmetric bending moment loads.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A double-sided load-bearing amorphous strip winding device includes an unwinding mechanism, a guide roller group, a tensioning mechanism, a control system, a correction mechanism, and a winding mechanism. The winding structure includes a first housing, a drive motor disposed within the first housing, a support roller passing through the side wall of the first housing, and a hydraulic chuck installed at the junction of the support roller and the first housing. The output end of the drive motor is connected to the support roller. The device also includes a second housing symmetrically arranged with the first housing. The second housing is equipped with a drive motor, support roller, and hydraulic chuck with the same structure as the first housing. The support rollers of the first housing and the second housing extend towards each other along the axial direction, and the two support rollers rotate in the same direction and at the same speed. The two support rollers together constitute a double-sided cantilever support structure for the iron core.

[0007] As a limitation of this utility model, it also includes a loading platform, on which the first box and the second box are assembled. A linear drive assembly is provided on the loading platform, and the output end of the linear drive assembly is connected to the second box. The second box moves linearly in a direction that is close to or away from the first box.

[0008] As a further limitation of this utility model: the linear drive assembly includes a drive component and a limiting component;

[0009] The drive unit includes a drive motor, a lead screw connected to the output end of the drive motor, and a lead screw nut threaded onto the lead screw; the lead screw nut is fixedly connected to the bottom of the second housing, and the lead screw extends axially toward the first housing;

[0010] The limiting component includes a slide rail fixed to the loading platform and a slider slidably disposed on the slide rail. The slide rail is arranged parallel to the lead screw, and the slider is fixedly connected to the bottom of the second housing.

[0011] As a further limitation of this utility model: a drag chain is provided between the loading platform and the second box.

[0012] As another limitation of this utility model: the unwinding mechanism has multiple unwinding racks, and a power component is provided at the position corresponding to each unwinding rack in the unwinding mechanism, with the output end of the power component connected to the corresponding unwinding rack.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0014] This invention improves upon existing amorphous strip winding devices. Specifically, it adds a second housing symmetrically arranged with the first housing. The second housing houses a drive motor, support rollers, and a hydraulic chuck with the same structure as the first housing. The support rollers of the first and second housings extend towards each other along their axial direction, rotating in the same direction and at synchronized speeds. Together, the two support rollers form a double-sided cantilever support structure for the iron core. In implementation, the iron core is fitted onto the two support rollers of the first and second housings. The two support rollers drive the iron core to rotate, achieving winding. Compared to existing technologies where only the support rollers on the first housing support the iron core, this device uses two support rollers to share the load, reducing the bending moment load on a single support roller, increasing the device's service life, and lowering the failure rate. This device can support iron cores and strip assemblies weighing over two tons, improving the continuous winding efficiency and product quality stability of amorphous strips.

[0015] In summary, this invention can support a core and strip assembly weighing over two tons, increasing the service life of the device, reducing the failure rate, and improving the continuous winding efficiency and product quality stability of amorphous strips. This invention is suitable for the continuous winding production of heavy-duty amorphous strips. Attached Figure Description

Detailed Implementation

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and do not constitute a limitation thereof.

[0025] The directional terms or positional relationships such as "left" and "right" used in the embodiments are based on the drawings in this utility model specification. Figure 5 The orientation relationships are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this utility model.

[0026] like Figures 3-6 As shown, this embodiment includes an unwinding mechanism 1, a guide roller group 2, a tensioning mechanism 3, a control system 4, a web-correcting mechanism 5, and a winding mechanism 6. The winding structure includes a first housing 7, a drive motor disposed within the first housing 7, a support roller 8 passing through the side wall of the first housing 7, and a hydraulic chuck 9 installed at the junction of the support roller 8 and the first housing 7. The output end of the drive motor is connected to the support roller 8, thereby driving the support roller 8 to rotate. This part is prior art, and the specific structure and working principle of the unwinding mechanism 1, the guide roller group 2, the tensioning mechanism 3, the control system 4, and the web-correcting mechanism 5 will not be described in detail in this embodiment.

[0027] The main improvements in this embodiment are twofold: first, the addition of a second housing 10; and second, the increase in the number of unwinding racks 17 on the unwinding mechanism 1.

[0028] I. Second box 10;

[0029] like Figure 3 , 5As shown in Figure 6, the second housing 10 is symmetrically arranged with the first housing 7. The second housing 10 is equipped with a drive motor, support rollers 8, and hydraulic chuck 9, which have the same structure as the first housing 7. The drive motors on the second housing 10 and the first housing 7 are located inside them and are not shown in the figure. Here, the drive motor is a servo motor. The drive motor, support rollers 8, and hydraulic chuck 9 are all existing technologies, and their structure and working principle will not be described in detail in this embodiment. The support rollers 8 of the first housing 7 and the support rollers 8 of the second housing 10 extend towards each other along the axial direction. The two support rollers 8 rotate in the same direction and at the same speed. The two support rollers 8 together form the double-sided cantilever support structure of the iron core 18. During winding, the support rollers 8 of the first housing 7 and the support rollers 8 of the second housing 10 jointly support the iron core 18, reducing the bending moment load borne by a single support roller 8, increasing the service life of the device, and reducing the failure rate. This device can support iron core 18 and strip assembly weighing more than two tons, improving the continuous winding efficiency and product quality stability of amorphous strip.

[0030] Furthermore, such as Figure 5 As shown, this embodiment also includes a loading platform 11, on which the first box 7 and the second box 10 are assembled. A linear drive assembly is provided on the loading platform 11, and the output end of the linear drive assembly is connected to the second box 10, driving the second box 10 to move linearly in a direction close to or away from the first box 7.

[0031] Specifically, in this embodiment, the linear drive assembly includes a drive component and a limiting component. For example... Figure 3-5 As shown, the driving component includes a drive motor 12, a lead screw 13 connected to the output end of the drive motor 12, and a lead screw nut threaded onto the lead screw 13; the lead screw nut is fixedly connected to the bottom of the second housing 10, and the lead screw 13 extends axially toward the first housing 7, that is, extends in the left-right direction. The limiting component includes a slide rail 14 fixed on the loading platform 11 and a slider 15 slidably disposed on the slide rail 14. In this embodiment, there are two slide rails 14, which are arranged parallel to the lead screw 13 and the lead screw 13 is located between the two slide rails 14. Each slide rail 14 has a slider 15 slidably engaged, and the slider 15 is fixedly connected to the bottom of the second housing 10. The principle of linear motion of the second housing 10 is as follows: the drive motor 12 rotates, causing the lead screw 13 to rotate. The second housing 10 tends to rotate with the lead screw 13, but because the slider 15 fixed at the bottom of the second housing 10 is locked on the slide rail 14, the second housing 10 cannot rotate. Under the threaded engagement of the lead screw and nut, the second housing 10 moves linearly along the axis of the lead screw 13, that is, moves in the left and right direction to move closer to or away from the first housing 7. The movement of the second housing 10 is to control the distance between the two support rollers 8 to accommodate iron cores 18 of different sizes.

[0032] Of course, the linear drive assembly can also be any existing structure that can provide linear drive force, such as a cylinder.

[0033] It should be noted that, as Figure 5 As shown, in this embodiment, the first housing 7 is also slidably disposed on the loading platform 11. The sliding arrangement is the same as that of the second housing 10. It is also moved by a drive motor, lead screw 13, lead screw nut, slide rail 14, and slider 15. The first housing 7 moves so that the iron core 18 corresponds with the unwinding mechanism 1, tensioning mechanism 3, etc., so that the amorphous strip can be wound on the iron core 18.

[0034] To improve this embodiment, a cable chain 16 is provided between the loading platform 11 and the second housing 10 to protect the cable. The cable chain 16 structure is existing technology and will not be described in detail in this embodiment.

[0035] II. Material feeding rack 17;

[0036] In the prior art, the unwinding mechanism 1 has only one unwinding rack 17, which is driven to rotate by a power component inside the unwinding mechanism 1 to achieve unwinding. To improve unwinding efficiency, such as... Figure 3 As shown, in this embodiment, the unwinding mechanism 1 has multiple unwinding racks 17, specifically four. Inside the unwinding mechanism 1, a power component is provided corresponding to the position of each unwinding rack 17. The output end of the power component is connected to the corresponding unwinding rack 17, allowing multiple unwinding racks 17 to rotate simultaneously, thus improving unwinding efficiency. Since the power component is existing technology, it will not be described in detail here.

[0037] In this embodiment, the position of the second housing 10 is adjusted, and the iron core 18 is fixedly fitted onto the two support rollers 8 of the first housing 7 and the second housing 10. The fitting method of the iron core 18 is the same as that of the existing single-sided cantilever support structure, except that in this embodiment, the two support rollers 8 share the load. The operation control system 4 causes the amorphous strip on the unwinding mechanism 1 to pass through the guide roller group 2, the tensioning mechanism 3, and the correction mechanism 5 in sequence into the winding mechanism 6. The drive motor in the first housing 7 and the drive motor in the second housing 10 rotate synchronously, causing the iron core 18 to rotate, thereby realizing the winding and forming of the amorphous strip.

[0038] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
