Description

Technical Field

[0001] The utility model belongs to the technical field of transformer silicon steel coil production, in particular to an automatic material pressing device in front of a buffer pit of a slitting line. Background Art

[0002] Slitting is the process of cutting and punching in silicon steel coil production. It cuts the rolled silicon steel coil into strips and supplies them to the next process to meet the needs of iron core production. During processing, the rolled silicon steel coil is taken and placed, passes through the buffer hole and finally passes through the cutting mechanism to complete the rectification and cutting work.

[0003] The existing automatic material pressing device in front of the buffer pit of the slitting line, such as the automatic material pressing device in front of the buffer pit of the slitting line disclosed in application No. CN201920734378.2, can effectively prevent the tail end of the silicon steel coil from suddenly falling into the buffer pit and damaging the silicon steel strip in the final stage of the existing slitting line by clamping the tail end of the silicon steel coil in front of the buffer pit, thereby ensuring the product quality of the slitting process.

[0004] However, in actual use, the plate-shaped clamping structure can easily scratch the surface of the silicon steel coil, thus affecting the product quality of subsequent core processing. Other structures using rollers cannot ensure the transportation of the silicon steel coil while ensuring clamping, and cannot flexibly adjust the spacing, and thus cannot meet the pressing requirements of silicon steel coils of different thicknesses. For this reason, we propose an automatic pressing device in front of the buffer pit of the slitting line to solve the above problems. Utility Model Content
