Description

Technical Field

[0001] The utility model relates to the technical field of tool setting devices, in particular to an automatic tool setting device for a high-precision longitudinal shearing line of silicon steel sheets. Background Technique

[0002] Silicon steel sheets refer to a kind of silicon-iron soft magnetic alloy with extremely low carbon content (after annealing, the carbon content is below 0.005%), and generally the silicon content is 0.5% - 4.5%. Adding silicon to iron can increase its resistivity and maximum magnetic permeability. It is mainly used to manufacture the iron cores of various transformers, motors and generators. Electrical steel sheets are divided into two categories, namely grain-oriented electrical steel sheets and non-oriented electrical steel sheets.

[0003] The Chinese utility model with the authorization publication number CN220659373U discloses a longitudinal shearing line of silicon steel sheets with a buffer protection device. When the device is in use, the first rotating rod and the first roller are buffered by the elastic recovery of the spring body to avoid squeezing and damaging the silicon steel sheets by the first rotating rod and the first roller. However, there are certain defects in the specific use of the device. For example, the distance between the cutting blades on the device is fixed. If silicon steel sheets of different widths need to be sheared, the whole set of blades needs to be replaced or complex adjustments need to be made, resulting in the inability to quickly adapt to the production requirements of different specifications. Therefore, it is necessary to redesign the automatic tool setting device for the high-precision longitudinal shearing line of silicon steel sheets in view of the above problems. Content of the Utility Model

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] The automatic tool setting device for a high-precision longitudinal shearing line of silicon steel sheets includes a bottom plate. Two side plates are fixedly connected to the upper end of the bottom plate and are symmetrically arranged. A rotating shaft is rotatably connected between the two side plates. A chute is formed through the outer wall of the rotating shaft. Two sliders are slidably connected in the chute. Arc-shaped blades are installed at both ends of the two sliders. The inner and outer diameters of the arc-shaped blades are the same as those of the rotating shaft. The two arc-shaped blades are combined to form a circular blade. A driving component for driving the two sliders to slide is installed in the chute.

[0007] Preferably, the driving component includes a double-headed threaded rod rotatably connected to the inner wall of the chute. The two sliders are both threadedly connected to the threaded sections of the double-headed threaded rod.

[0008] Preferably, a limiting rod is fixedly connected to the inner wall of the chute. The two sliders are both slidably connected to the outer wall of the limiting rod.

[0009] Preferably, the arc-shaped blade and the slider are connected by two sets of screws, and an outer frame is fixedly connected to the outer wall of the rotating shaft.

[0010] Preferably, the outer wall of the outer frame is U-shaped, and a first motor is fixedly connected to the inner and outer walls of the rotating shaft.

[0011] Preferably, a second motor is fixedly connected to the outer wall of one of the side plates. The end of the output shaft of the first motor is coaxially and fixedly connected to the double-headed threaded rod, and the end of the output shaft of the second motor is coaxially and fixedly connected to the outer frame.

[0012] The utility model has the following beneficial effects:

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Refer to Figures 1-3, an automatic tool-adjusting device for a high-precision silicon steel sheet longitudinal shearing line, comprising a bottom plate 1. Two side plates 2 are fixedly connected to the upper end of the bottom plate 1 and are symmetrically arranged. A rotating shaft 3 is rotatably connected between the two side plates 2. A chute 5 is formed through the outer wall of the rotating shaft 3. Two sliders 12 are slidably connected in the chute 5. Arc-shaped blades 4 are installed at both ends of the two sliders 12. The inner and outer diameters of the arc-shaped blades 4 are the same as those of the rotating shaft 3. The two arc-shaped blades 4 are combined to form a circular blade. A driving component for driving the two sliders 12 to slide is installed in the chute 5; the sliders 12 can be flexibly adjusted in the chute 5, thereby adjusting the relative positions of the two arc-shaped blades 4.

[0021] The driving component includes a double-headed threaded rod 9 rotatably connected to the inner wall of the chute 5. The two sliders 12 are both threadedly connected to the threaded sections of the double-headed threaded rod 9. A limiting rod 10 is fixedly connected to the inner wall of the chute 5. The two sliders 12 are both slidably connected to the outer wall of the limiting rod 10; the setting of the double-headed threaded rod 9 can accurately and synchronously adjust the distance between the blades, ensuring that the blades can be quickly and accurately adjusted to the required positions, reducing the adjustment time and operation difficulty, and improving the cutting accuracy at the same time.

[0022] The arc-shaped blade 4 is connected to the slider 12 through two screws 11. An outer frame 6 is fixedly connected to the outer wall of the rotating shaft 3. The outer wall of the outer frame 6 is U-shaped. A first motor 7 is fixedly connected to the inner and outer walls of the rotating shaft 3. A second motor 8 is fixedly connected to the outer wall of one of the side plates 2. The end of the output shaft of the first motor 7 is coaxially fixedly connected to the double-headed threaded rod 9. The end of the output shaft of the second motor 8 is coaxially fixedly connected to the outer frame 6.

[0023] In the present utility model, when the device is specifically used: when adjusting the positions of the multiple arc-shaped blades 4, the first motor 7 is started to drive the double-headed threaded rod 9 to rotate. When the double-headed threaded rod 9 rotates, it drives the two sliders 12 to move precisely and synchronously along the chute 5. The sliding of the sliders 12 in the chute 5 is guided by the limiting rod 10, ensuring that the sliders 12 will not deviate from the track during the movement, thereby maintaining the accuracy of the adjustment. The movement of the sliders 12 directly drives the arc-shaped blades 4 installed thereon to adjust the relative positions. The two arc-shaped blades 4 form a complete circular blade structure through combination. As the sliders 12 move, the distance between the blades is accurately adjusted to the set value.

[0024] After the position and angle of the blades are adjusted, the silicon steel sheet starts to be conveyed along the longitudinal shearing line. When the silicon steel sheet enters the blade area, the circular blade performs precise longitudinal cutting on it. Through the previous automatic adjustment, the blade can complete the cutting task with high precision, ensuring that the cutting size of the silicon steel sheet meets the production requirements; at the same time, the arc-shaped blade 4 is connected to the slider 12 through the screw 11, and it can be quickly disassembled and replaced during replacement.

[0025] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
