Technical Field

[0001] The patent of this invention relates to the technical field of V-shaped blade serrated knife for reducing shear force, and specifically to a V-shaped blade serrated knife device capable of reducing shear force. Background Art

[0002] In most of the existing automotive industries, the shearing of steel coils is a common process. Shearing is the process of converting steel coils from the original coil state into flat sheets of the required size.

[0003] This process is usually done in a factory or fabrication shop. First, the coil is placed on a piece of equipment called a decoiler. The decoiler unwinds the coil, flattening it and exposing a larger shear surface.

[0004] When processing high-strength steel plates, traditional shearing serrated knives will cause the upper and lower fixed brackets to loosen due to the shear force generated instantly when shearing the steel plates, causing changes in the gaps between the upper and lower serrated knives fixed thereon, resulting in uneven cutting of the processed steel plates, affecting the yield rate of the processed steel plates, and also causing tough notches on the serrated knives, affecting the service life of the shearing serrated knives. Therefore, it does not meet the existing needs. In this regard, we have proposed a V-shaped blade serrated knife device that can reduce the shear force.
