Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a permalloy sheet rolling device. Background Technology

[0002] Permalloy is a nickel-iron alloy with very low coercivity, meaning its hysteresis loop is very narrow. Micromagnetic elements or circuits made from permalloy exhibit very low magnetic reluctance, making it an excellent conductor for weak magnetic fields and playing an important role in weak magnetic field measurements. Furthermore, due to its high resistivity, it can be used as a material for precision resistors and strain gauges. Currently, it is widely used in the fabrication of magnetic shielding covers for electronic medical devices.

[0003] Magnetic shielding covers are mostly cylindrical, while permalloy plates are mostly flat sheets. During the production and processing of shielding covers, the permalloy plates typically need to be wound into a cylindrical shape, thus requiring the use of a winding device. However, traditional shielding cover processing often relies on manual winding and welding because medical devices are produced in small batches and cannot be mass-produced on production lines. This makes manual processing of larger shielding covers very difficult and hinders efficiency.

[0029] As a further aspect of the present invention: the shaping component includes two first legs 2, and mounting cylinders 3 are fixedly connected to the top surfaces of the two first legs 2 respectively. Several sliding grooves 4 are respectively opened on the opposite sides of the two mounting cylinders 3. Sliding plates are slidably connected in the two opposite sliding grooves 4. The outer side of the sliding plate has an arc-shaped structure. One end of the sliding plate is connected to a driving component, which is disposed in the inner cavity of the mounting cylinder 3 and fixedly connected to the base 1.

[0030] In the above technical solution, the first leg 2 provides stable support for the mounting cylinder 3, which is used to install and fix components such as the slide plate and drive assembly. The groove 4 allows the slide plate to slide on the side of the mounting cylinder 3, thereby changing the diameter of the circle formed by the slide plate and thus adjusting the diameter of the wound cylinder. The outer surface of the slide plate has an arc-shaped structure, which can form good contact and fit with the permalloy plate, ensuring the winding effect and product quality. The drive assembly is used to drive the slide plate to slide, achieving precise adjustment of the cylinder diameter.

[0031] As a further embodiment of the present invention: the slide includes two sliders 5, and two opposite sides of the sliders 5 are fixedly connected with slide bars 6.

One end of the first pre-bending roller 15 passes through the third leg 14 and is connected to a motor 17. The motor 17 is fixedly connected to the third leg 14.

[0036] In the above technical solution, the third support leg 14 provides stable support and fixation for the first pre-bending roller 15 and the second pre-bending roller 16. A gap is provided between the first pre-bending roller 15 and the second pre-bending roller 16, allowing the permalloy plate to pass smoothly and be bent. The motor 17 is used to drive the first pre-bending roller 15 to rotate, which in turn drives the second pre-bending roller 16 to rotate together by rolling the permalloy plate, thereby realizing the bending process of the permalloy plate.

[0043] As a further aspect of the present invention: the scale 20 indicates the distance from the center of the mounting cylinder 3 to the outer side of the top plate 7, that is, the diameter of the largest circle enclosed by all the outer sides of the top plates 7.

[0044] In the above technical solution, by reading scale 20, users can directly know the diameter of the circle formed by the top plate 7, thereby achieving precise control and adjustment of the diameter of the wound cylinder. This design not only improves the accuracy and reliability of the device, but also provides users with more intuitive and accurate operating guidance.

[0045] The working process of this embodiment is as follows:

[0046] In use, this invention requires pre-calculation of the pre-set diameter cylindrical shape to obtain the length of the straight permalloy plate, which is then cut. The permalloy plate is fed into the gap between the first pre-bending roller 15 and the second pre-bending roller 16. By rolling the first pre-bending roller 15 and the second pre-bending roller 16 against each other, the straight permalloy plate is rolled into a permalloy plate with a certain curvature, making it easy to wrap around the outside of the top plate 7. Then, the two ends of the permalloy plate are aligned, and the aligned ends of the permalloy plate are welded using external welding equipment, thus completing the processing of the permalloy cylinder. Finally, utilizing the elasticity of the top plate 7, the top plate 7 is bent and disassembled, thus unloading the permalloy cylinder.
