[CN202110543557.X] An installation method for prolonging the service life of the locking head of the shear blade of a shearing machine Title: An installation method for prolonging the service life of the locking head of the shear blade of a shearing machine Application No.: CN202110543557.X Applicant: Baowu Group Echeng Iron and Steel Co., Ltd. Application Date: 2021-5-19 Patent Type: Invention Application This invention is an installation method for prolonging the service life of the shear blade locking head of the following steps: 1) Wrap a certain thickness of lead wire at the intersection of the front thread of the locking head and the polished rod; 2) Insert the locking head into the mounting hole of the locking cylinder, initially rotate the locking head so that the threaded part of the locking head basically enters the mounting hole, and reserve a gap between the head of the locking head and the locking cylinder; 3) Insert a pre-prepared special measuring tool into the reserved gap between the locking head and the locking cylinder; 4) Continue to rotate the locking head so that the locking head is tightly attached to the measuring plane A of the special measuring tool; 5) Remove the locking head and measure the thickness of the lead wire; 6) match the washer according to the thickness of the lead wire and install it on the locking head 7) Reinstall the locking head and tighten it; the present invention overcomes the shortcomings of low installation dimensional accuracy when installing the locking head by the existing installation method, and prolongs the service life of the locking head.
