Description

Technical Field

[0001] This utility model relates to the field of silicon steel sheet processing technology, and more specifically, to a silicon steel sheet shearing device for transformer production. Background Technology

[0002] Silicon steel sheets are a soft magnetic alloy of silicon and iron with extremely low carbon content, typically containing 0.5-4.5% silicon. Adding silicon increases the resistivity and maximum permeability of iron, while reducing coercivity, iron loss, and magnetic aging. Its main application is in the manufacture of cores for various transformers, motors, and generators. Finished products require low iron loss, high magnetic induction intensity under strong magnetic fields, a smooth and flat surface, uniform thickness, good stamping properties, good adhesion and weldability of the surface insulating film, and minimal magnetic aging. Silicon steel sheets are generally packaged in rolls upon leaving the factory and are then cut into smaller rolls before use.

[0003] A Chinese patent publication number CN220259726U discloses a silicon steel sheet shearing device for transformer production, comprising a cutting table and a fixed base connected to the top of the cutting table. The fixed base is connected to two cylinders, and the power output end of each cylinder is connected to a mounting base. The mounting base is connected to a detachable shearing blade, and the mounting base is connected to a clamping mechanism for clamping the shearing blade. The clamping mechanism includes four pressure blocks, four drive plates, two moving plates, and studs. The studs are used to drive the two moving plates to move closer or further apart. The two ends of each moving plate are connected to the drive plates. The pressure blocks are fixed to the ends of the drive plates. The shearing blade has pressure grooves on both sides, and the ends of the pressure blocks match the pressure grooves. The mounting base is connected to a positioning mechanism for positioning the two moving plates.

[0004] Another problem with the above-mentioned device is that when cutting silicon steel sheets, there is no protective cover on the outside of the shearing blade, which causes the debris generated by the shearing blade to fly everywhere during the cutting process, which can easily injure the operator.

The output end of the electric push rod 4 first pushes the protective cover 8 to contact the top of the worktable 1 through the strip plate 7 under the action of the spring 6, covering the part of the silicon steel sheet to be cut. Then, the output end of the electric push rod 4 pushes the shearing blade 17 downward through the mounting block 20 to cut the silicon steel sheet. The two sets of guide rods 5 drive the strip plate 7 to move downward along the round rod 18. At this time, the spring 6 is in a compressed state. After the shearing is completed, the output end of the electric push rod 4 retracts the shearing blade 17, and at the same time, the spring 6 rebounds. The strip plate 7 drives the protective cover 8 away from the silicon steel sheet through the spring 6.
