Description
Technical field
The present invention relates to negative camber manufacture fields, and in particular to a kind of device and processing method of band saw sawing Inner arc.
Background technology
In recent years in sheet metal, cabinet-wood, ceramic stone implement, glass industry etc., inside and outside circular arc or circular is processed
Method is varied, but be exactly nothing but cut by line sawing device, plasma cut, high pressure waterjet or lathe milling
Processing carries out.For positive camber（Major part is outer circle）It processes fairly simple, passes through the program of CNC machine and workpiece work top
The processing feeding of CNC machine is completed in compiling and the rotation of work top comes together to complete required shape track processing.But for interior
For Machining of Curved Surface compared to positive camber with regard to more complicated, major part processes realization using Inner arc cutter in lathe, or use etc.
Ion cutting is processed, and is also exactly that destructiveness is processed for one section using line sawing device from outside, such method
The thickness of processing introversion face piece is all than relatively thin, and radius of curvature is all smaller, generally R200-500mm.But as big specification is non-
The demand development of curved-surface piece inside and outside specification（Such as space flight, military industry field φ 2890mm large-diameter circular rings）, should develop it is a kind of it is low at
This efficient technical method is processed and formed at one time to solve positive camber in big specification part.
Through retrieving the open source literature in relation to plank Inner arc processing method or equipment, there are also be now listed below：

A kind of automatic cutting inner circle device, including transmission component and cutting assembly are disclosed with novel, the transmission component includes automatic
Cutting machine bottom plate, motor, speed reducer, automatic gas cutting machine big belt wheel one, automatic gas cutting machine big belt wheel two, automatic gas cutting machine are small
Belt wheel one, automatic gas cutting machine small pulley two, automatic gas cutting machine transmission shaft, speed reducer base, bearing block, bearing block fixed plate, skin
Band and bearing support lining plate, the cutting assembly include automatic gas cutting machine cylindrical sleeves, clamp nut, automatic gas cutting machine reinforcing rib
Plate, automatic gas cutting machine claw, automatic gas cutting machine burning torch fixed plate, automatic gas cutting machine burning torch fixing axle, burning torch and baffle, pass through biography
Dynamic component and cutting assembly are realized carries out inner circle processing to end plate.The utility model compares existing lathe process inner circle device,
Cutting speed is fast, high-quality, efficient, at low cost, the dimensionally stable of inner circle, and the consistency of size is good, especially big to surplus
End plate advantage it is quite apparent.
From the above-mentioned published patent document, it is known that, documents 1 disclose it is a kind of multi-sheets are spliced into it is cylindric
Inside and outside circle processing is carried out in lathe, is fixed multi-sheets by special tooling and is completed processing in lathe；Documents 2 disclose
A kind of carpenter's scroll saw and work top are combined the processing for realizing timber inner circle, and method is to open through slot in workpiece table top,
Scroll saw, which enters along through slot inside workpiece, to be cut, and the processing of annulus part is not suitable for；Documents 3 disclose cuts automatically
Rifle is implemented in combination with inner circle processing with movable component.
Disadvantage of the existing technology：（1）Processing turning that processing negative camber is combined using lathe and round tool or
Milling technology, it is relatively difficult for processing larger-diameter inner circle；（2）Jigsaw device is realized by the movement of saw blade and workbench
The processing of interior positive camber, but be that there is destructiveness by feed of slotting for the processing of negative camber；（3）Conventional plasma is processed
The technology of positive camber, more commonly used for glass and steel industry in the irregular part of big specification, but for the big of field of aluminum alloys
The fewer utilization of Machining of Curved Surface inside and outside specification part, especially thicker wall thickness part, processing cost are also relatively high.
