As a kind of preferred version, the method for described employing Standard Module processing arbitrary circular arc comprises the steps:

A) required circular arc is divided into the N equal portions;

B) calculate the length of run L:L=L1+L2+ that single length of run sum in the described N equal portions obtains required Machining Arc ... + Ln;

C) respectively with N1 ... Nn is that the shelves material level is put behind the bending adjusting of centerline;

D) respectively with C1 ... the angle value of Cn is adjusted slide block and is slided into the degree of depth;

E) finish technological forming by normal bending technique program.

As further preferred version, in step a), establish at least 4 broken lines in starting point and end points side, make circular arc and straight line rounding off, L2, L3=Ln, Ln-1 and equal half of L-2, the shortest broken line length is greater than 1/2V, (V is the size of Bending Mould V groove).

As further preferred version, normal bending technique program adopts the bending of standard Bending Mould in the step e).

As further preferred version, the bending technique program further comprises preliminary bending and meticulous bending in the step e); Described preliminary bending is the length of run that reserves circular arc; Meticulous bending is to process the circular arc that needs in length in reserve.

Compared with prior art, a kind of method that adopts Standard Module processing arbitrary circular arc of the present invention is utilized the processing of standard Bending Mould, in low-cost situation, process the arbitrary circular arc that needs, the factors such as technique, equipment, mould that reduce are to the restriction of design, and precision is relatively high, applied widely, additional consumptive material, processing step is simple, is applicable to the panel beating industry, mechanical processing industry, development phase of new product particularly, so its application prospect is very wide.

The specific embodiment

Below in conjunction with embodiment and to accompanying drawing to the present invention do further in detail, intactly explanation.

The invention provides the method that adopts Standard Module processing arbitrary circular arc, to adopt the processing of standard Bending Mould, be illustrated in figure 1 as circular arc and divide schematic diagram.

Embodiment 1 is described as follows as example take the circular arc of processing R200, and shown in Fig. 2 A to Fig. 4 J, this processing method is as follows:

Selection standard 2mm plate and V groove are 16 Bending Mould;

Step a) is divided into nine sections of 10+20+20+20+20+20+20+10 with the circular arc of R200, and 10>0.5V wherein is shown in Fig. 2 A;

Step b) is calculated part flattening size (mm): 20+49+72+33+(10+20+20+20+20+20+20+10)+and 33+37+24-3.5*0.5=410.5, shown in Fig. 2 B;
