Description
technical fieldthe invention belongs to field of machining, particularly relate to a kind of handle of a knife being applied to high-speed cutting.
background technologyin field of machining, high-speed cutting has become the necessary means of highly-efficient processing, difficult-to-machine material processing, dry cutting, hard machining, and high-speed tool system is one of key technology realizing High-speed machining.High-speed tool system refers to the system of connections of main shaft and the cutter be made up of main shaft, handle of a knife, chuck, cutter and clamp system, and tool system comprises main shaft-handle of a knife interface and cutter-handle of a knife interface, and its core is handle of a knife.Shown by machining Practice, common 7:24 tapering BT tool system causes rigidity and positioning precision to decline and can not be used for High-speed machining because high speed centrifugation expands, in order to tackle high speed centrifugation expansion issues, last century late nineteen eighties Germany, the U.S., Japan and other countries develop dual contact (conical surface and end face) high-speed tool system in succession: a class adopts the short wimble structure of hollow, as the tool system such as Capto of the HSK of Germany, the KM of the U.S. and Sweden; Another kind of is the modified of traditional B T tool system, as Japanese Big-Plus, NC5,3Lock, WSU, AHO etc.
Wherein, HSK is the representational hollow high-speed tool system of most, and it takes dual contact, hollow and thin-walled, the short wimble structure of 1:10 Small Taper, and utilizes hollow handles to use external-expanding type clamp system that centrifugal force is converted into clamping force.This alleviates high speed centrifugation expansion issues to a certain extent, but still existing problems: (1) limit speed is still on the low side, can not meet higher rotation speed requirements; (2) intensity and toughness is low, yielding fracture, not as having the solid handle of a knife in rigid surface and toughness heart portion; (3) bad dynamic performance.Hollow taper shank and local dissymmetrical structure easily cause vibration; (4) handle of a knife serious wear, the life-span is low.The self-locking of 1:10 tapering taper shank makes handle of a knife load and unload difficulty, wearing and tearing aggravation; Outer expanding clamp system makes taper-face contact uneven, causes taper shank concentrated wear serious; (5) hollow structure makes handle of a knife collet segment move forward, and cutter Mold processing is large.In addition, the solid handle of a knife of dual contact is with the Big-Plus of the 7:24 shank tapering of Japan for representative, and the advantage of this handle of a knife is: joint stiffness is high, and cutter overhangs little, compatible with common BT handle of a knife, but still it is low to there is limit speed, and the accuracy of manufacture requires the shortcomings such as high.
As fully visible, the in-problem root of existing High-speed Tool Shank be exactly main shaft-handle of a knife interface high speed centrifugation expand do not mate, namely the centrifugal expansion of handle of a knife is less than the centrifugal expansion of main shaft and causes limit speed, joint stiffness and positioning precision low, and reasonable head it off is the basic place of improving tool system performance.
