(2) use hole flanging mold to carry out hole flanging to described macropore, process the hole flanging limit that described macropore hole wall extends to the side in this hole;
(3) use flanging die to carry out flange in the middle part of the dual-side of described base-material of cranking arm, flange direction is identical with the hole flanging direction in step (2);
(4) use V-arrangement bending flanging die, from the mid portion of described base-material of cranking arm, described base-material symmetry of cranking arm is bent into biside plate part, described biside plate part shape has angle, described in the crank arm mid portion of base-material remain a middle plane;
(5) bend forming die is used to carry out 2 ~ 4 bending and moldings to described base-material of cranking arm continuously along the wrap direction in above-mentioned (4) step, the angle of the described angle that described biside plate part is formed progressively diminishes, last bending and molding terminates rear described biside plate part and is parallel to each other, and described biside plate part is vertical with described middle plane;
(6) use bending die step (5) is completed described in the crank arm inward at both ends of base-material bend, crank arm described in the maintenance middle part of base-material is straight, described biside plate part is still parallel to each other, and described biside plate part is still vertical with described middle plane, required for formation crank arm.
In a preferred embodiment of the present invention, when carrying out Bending Processing in described step (4) and step (5), circular arc is all processed in junction between described biside plate part and described middle plane, forms the circular sliding slopes between described biside plate part and described middle plane.
The invention has the beneficial effects as follows: it is shaping that this processing method mould carries out multi-step Continuous maching to base-material of cranking arm, required product of cranking arm can be gone out by overall processing, compare split type processing and carry out welding combination again, this processing method can ensure better process the dimensional tolerance precision and form and position tolerance precision of cranking arm, working (machining) efficiency is high, life of product is long, and quality is more reliable, and yields is higher.

Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Please refer to Fig. 1 and Fig. 2, processing method of cranking arm of the present invention comprises the following steps:
(1) use Linear cut or Methods of OFC-A to process base-material 4 of cranking arm, process macropore 3 cranking arm on base-material 4;
(2) use hole flanging mold to carry out hole flanging to described macropore 3, process the hole flanging limit 1 that described macropore 3 hole wall extends to the side in this hole;
(3) use flanging die to carry out flange in the middle part of the dual-side of described base-material 4 of cranking arm, flange direction is identical with the hole flanging direction in step (2); The flange 5 formed is vertical with the dual-side of base-material 4 of cranking arm, and the middle machining state of now cranking arm as shown in Figure 2.
(4) use V-arrangement bending flanging die, from the mid portion of described base-material 4 of cranking arm, described base-material 4 symmetry of cranking arm is bent into biside plate 6 part, described biside plate 6 part shape has angle, described in the crank arm mid portion of base-material 4 remain a middle plane 2;
(5) bend forming die is used to carry out 2 ~ 4 bending and moldings to described base-material 4 of cranking arm continuously along the wrap direction in above-mentioned (4) step, the angle of the described angle that described biside plate 6 part is formed progressively diminishes, last bending and molding terminates rear described biside plate 6 part and is parallel to each other, and described biside plate 6 part is vertical with described middle plane 2; Carrying out repeatedly bending and molding can avoid the bending deflection of a bending excessive, is conducive to the accurate to dimension and the form and position tolerance precision that ensure workpiece.
