Description
Technical field
The present invention relates to negative camber manufacture field is and in particular to device and the processing method of sawing Inner arc sawed by a kind of band.
Background technology
In recent years in sheet metal, cabinet-wood, ceramic stone implement, glass industry etc., circular arc or circle inside and outside processing
Method is varied, but be exactly nothing but carry out cutting by line sawing device, plasma cutting, high pressure waterjet or lathe milling
Processing is carried out.For positive camber（Major part is cylindrical）Processing is fairly simple, by the program of CNC machine and workpiece work top
The rotation of processing feeding and work top that compiling completes CNC machine comes together to complete the processing of required form track.But for interior
Machining of Curved Surface compares that positive camber is just more complicated, and major part processes realization using Inner arc cutter in lathe, or employing etc.
Ion cutting is processed, and is exactly also that destructiveness is processed from the feeding of one section of outside using line sawing device, such method
Thickness all ratios of processing introversion face piece are relatively thin, and radius of curvature is all smaller, generally R200-500mm.But it is non-to be as big specification
The demand development of curved-surface piece inside and outside specification（As space flight, military industry field φ 2890mm large-diameter circular ring）, a kind of low one-tenth should be developed
This efficient technical method is solving the disposable machine-shaping of positive camber in big specification part.
Also have about the open source literature of sheet material Inner arc processing method or equipment through retrieval, be now listed below：

Cutting speed is fast, quality is good, efficiency high, low cost, the dimensionally stable of inner circle, and the concordance of size is good, especially big to surplus
End plate Dominant Facies when substantially.
From patent documentation disclosed above it is known that, documents 1 disclose one kind multi-sheets are spliced into cylindric
Carry out inside and outside circle processing in lathe, complete to process in lathe by the fixing multi-sheets of special frock；Documents 2 disclose
A kind of carpenter's scroll saw and work top combine and realize the processing of timber inner circle, and its method is to open through slot in workpiece table top,
Scroll saw enters along through slot and is cut inside workpiece, is not suitable for the processing of annulus part；Documents 3 disclose cuts automatically
Rifle and moving component are implemented in combination with inner circle processing.
The shortcoming that prior art exists：（1）The processing processing turning that combined using lathe and round tool of negative camber or
Milling technology, for processing, larger-diameter inner circle is relatively difficult；（2）Jigsaw device passes through saw blade and the motion of workbench is realized
The processing of interior positive camber, but the processing for negative camber is by feed of slotting, and has destructiveness；（3）Conventional plasma is processed
In the big irregular part of specification, the technology of positive camber, the more commonly used for glass and steel industry, but big for field of aluminum alloys
The fewer utilization of Machining of Curved Surface inside and outside specification part, particularly thicker wall thickness part, processing cost is also higher.
