Background

The lock core is a core component of a common lockset, such as a blade lock, a spring lock and the like. When the existing lock core is manufactured, a cylindrical lock core blank needs to be grooved, a broach is generally used for processing the lock core groove, and the broach is a forming cutter for broaching. The tool surface has a plurality of rows of cutter teeth, and the size and shape of each row of cutter teeth increase and change from the cutting-in end to the cutting-out end. When the broaching tool does broaching movement, each cutter tooth cuts metal with certain thickness from the blank to finally obtain the required size and shape of the lock cylinder groove; in the prior art, when the lock cylinder slot-producing machine works, a common broach works continuously, and corresponding cooling equipment is not used for cooling the broach and a blank in time, so that the equipment is easy to wear, and the service life is seriously influenced; meanwhile, metal scraps generated during groove drawing are accumulated on a workbench or even a broach, blanks are damaged during processing, the quality of finished products is affected, a brush is hung above the broach on some production lines, the broach contacts with bristles in the reciprocating movement process to clean the scraps, certain packaging effects are achieved, the bristles are easy to drop during long-term use, and the quality of the processed lock cylinder is also affected by the bristles dropped on the broach; and when the existing lock core slot-producing machine is used for producing locks with different specifications, the debugging process is complex, the labor and the time are wasted, the matching among all parts is difficult to control, and faults such as material blocking, material falling and the like are easy to occur.
