Description

Technical Field

[0001] The invention belongs to the technical field of transformer core processing, and in particular relates to a cutting device for transformer core silicon steel sheets. Background Art

[0002] Shearing device is a device that cuts items into required sizes according to settings, suitable for users of different sizes and requirements. It is widely used in metal recycling plants, scrap car dismantling yards, smelting and casting industries to perform cold shearing, pressing and flanging of various shapes of steel and various metal materials.

[0003] Among them, silicon steel sheets are used as plug-ins for transformer cores. During processing, the rolled long silicon steel sheets need to be cut into Figure 1 The target silicon steel sheet (a) with pointed shapes at both ends (unequal-sided hexagon) shown in the figure is currently sheared using a shearing device. Generally, a rolled silicon steel sheet of suitable width is first cut according to the length of the target silicon steel sheet (the distance H between the sharp corners at both ends), and finally cut into rectangular silicon steel sheets. Then, the four right angles of the rectangular silicon steel sheet are cut off, and finally a shape of an equal-sided hexagon with pointed ends is formed. In this process, multiple size positioning and shearing actions are required, which is very cumbersome and troublesome, and seriously affects the shearing efficiency and accuracy of the silicon steel sheet. In addition, the scraps (b) generated during each shearing process need to be picked up and collected manually, which prolongs the interval between the shearing actions, further affects the shearing efficiency of the silicon steel sheet, and wastes labor costs. Third, for the silicon steel sheet that has been sheared on the shearing platform, because of its thin thickness, it sticks to the shearing platform, and it is inconvenient to grab it with hands when taking it away, which is relatively inconvenient.

[0004] A Chinese patent with application number: 202310789565.1 disclosed a shearing device for transformer silicon steel sheets, including a shearing platform, an "X"-shaped shearing knife is arranged above the middle of the shearing platform, the shearing knife is connected to the shearing platform through a lifting mechanism, the lifting mechanism drives the compacting and unloading comprehensive mechanism through the moving mechanism to compact the silicon steel sheet or unload the two scraps produced by shearing into the front and rear collection boxes respectively, and the left and right sides of the right silicon steel sheet are lifted to a certain height and then released through the lifting and releasing mechanism; the above-mentioned lifting mechanism, the moving mechanism, the compacting and unloading comprehensive mechanism and the lifting and releasing mechanism are cleverly coordinated to form an interlocking overall mechanism, and when the shearing knife moves to During the process of lowering the knife and resetting upward, the silicon steel sheets can be pressed during shearing, the scraps can be automatically transferred and unloaded after shearing, and the sheared silicon steel sheets can be lifted to a certain height and released after shearing. An overall structure can complete multiple functions simultaneously, with a compact structure and strong economy. Although the "x"-shaped shearing knife set in the device can shear the silicon steel sheets into the shape of unequal-sided hexagons with pointed ends, in the production process of transformer cores, a variety of silicon steel sheets of different shapes are often required. The shape of the silicon steel sheets sheared by the device is too single and cannot meet the requirements of cutting silicon steel sheets of different shapes, affecting the shearing efficiency and shearing quality of the silicon steel sheets.
