Description

Technical Field

[0001] The utility model belongs to the field of rewinding and laminating machines, in particular to a blade used for chip breaking of steel parts. Background Art

[0002] By 2024, the market will primarily focus on welded blade reamers, which have become the currency of the tool industry. However, in the machining of steel parts, chip breaking has been a challenge, as the welded structure limits the design of the reamer's chip-breaking edge.

[0003] Steel chipbreaker inserts (reamer blades) are die-cast, eliminating the time previously spent on grinding. This process opens up a wider range of chipbreaking options. Conventional reamers, which are ground directly from a solid hardened tool body, have significant limitations in the type of chipbreaking geometries that can be ground. The advent of reamers has broadened the tool's process capabilities. Die-casting can achieve chipbreaking geometries that are not possible with conventional reamers.

[0004] Conventional reamers for steel machining use either a right-hand spiral with a rear row or a left-hand spiral with a forward thrust, or incorporate small chipbreakers on the rake face. However, these chips cannot be broken in practice. Furthermore, conventional boring tool inserts operate at a single point, which can easily cause chatter when too many edges are present. Conventional inserts also lack stable machining performance in applications requiring high cylindricity, increasing labor costs and reducing machine tool availability. Utility Model Content

[0011] Furthermore, the cutting edge band B and the first barrier band B cooperate to form a circular arc edge band for machining. The formed circular arc edge band can improve efficiency by multi-edge cutting like a conventional reamer, and the edge band also plays a supporting role to make the cylindricity of the mounting hole more stable.
