Technical field
The utility model relates to clamping tool for machine work technical fields, refer in particular to a kind of suitable for large-sized high-temperature alloy thin-walled
The turning clamp of annular workpieces.
Background technique
Machining Technology for Cutting is the technology being now widely used in machinery manufacturing industry, during cutting technology,
While basis material extra on cutting off workpiece, workpiece subjects the cutting force on cutting tool, and due to
Workpiece and cutting tool generate the relative motion of high speed, produce a large amount of cutting heat, these cutting heats are partly delivered to workpiece
On, so that workpiece surface crystal inside tissue generates a series of variation because heated, there is drawing hardening effect, due to workpiece sheet
The difference of body material property, it is also different that the phenomenon that processing hardening occur in different workpieces, for High-temperature resistant alloy material workpiece
For, when carrying out rough turning processing, surface would generally generate the hardened layer of one layer of 0.05~0.15mm or so, and hardness is higher by
Material itself 50%~100%, and the material that finish turning adds man-hour requirement to remove is less, usual cutting depth 0.02~
0.15mm range causes cutter that can directly cut piece surface hardened layer, although using the hard alloy for capableing of work hardening layer
Cutter, but turning part hardened layer must be such that cutting force caused by cutting tool increases, for thin wall component, by
Relatively thin in itself wall thickness, when increasing cutting force, the cutting force that workpiece is born also is increased accordingly, and workpiece thin-walled is made shape occur
Become, influence processing quality, processing efficiency is also difficult to improve, for this purpose, only cutting by using sharper turning cutting tool, reduction
The method that speed is processed is resolved, although using sharper cutter and reducing cutting speed and can reduce
Tool in Cutting power reduces extruding force suffered by part, but sharp cutter manufacture is difficult, and wears quickly, the cutter proportion of goods damageds
It is very big.
