Description

The soft punch Compound Forming of Bulging of a kind of rigidity frock
Technical field
The utility model relates to a kind of frock of processing boss bulging part, relates in particular to the soft punch Compound Forming of Bulging of a kind of rigidity frock.
Background technology
Soft flange is an important and vital part on hoop component (APP 31.02) as shown in Figure 1, is mainly used in Aeronautics and Astronautics, steamer field, owing to bearing at work high pressure, therefore, requires part deformation even.Material adopts 1Cr18Ni9Ti-δ 0.8 (GJB2296) aviation stainless steel tube, thickness of pipe wall 0.8.
For producing boss bulging part, the problem of most critical is how to resolve punching press (application of force) direction and the demoulding contradiction of part in punch and matrix (or mould) at boss bulging position.At present interrelated data introduction, generally all adopts traditional pressure processing method, as spinning (roll extrusion) bulging process, and rubber (or polyurethane rod) bulging process, and hydraulic bulging process, rigidity punch bulging process etc.; But these processing methods all exist certain limitation.
As spinning (roll extrusion) forming technology, its size φ 50.8 + 0.25wayward, the uniformity of size is poor, and its waste product is many, produces difficulty, and reliability extreme difference can not meet and adapt to product quality and batch product requirement.
According to technology Calculation, the bulge coefficient of part: K=d max/ d=66/48=1.375 > K the limitif the soft mode bulging that adopts liquid or rubber etc. to carry out as transmission medium, although in Bulging Process, blank deformation comparison is even, due to K > K the limit, this workpiece easily breaks, and boss narrow slit is little in addition, and the ability of the deep enough small gap of rubber (or polyurethane rod) energy is poor, and elasticity amount of recovery is large, and unfavorable for the bulging of narrow slit.And productivity ratio is lower, workman's operating condition is poor.Equally, directly utilize the mechanical bulging of mould rigid bulging, although it is high to have production efficiency, easy to operate advantage, makes workpiece easily break too, because the bulge coefficient of these two kinds of expanding methods is more or less the same; Especially for the special soft flange part of boss bulging of structure, bulging is high, narrow is its feature, and adopts pipe forming technology, and shaping difficulty is large; More easily produce unstability wrinkling, break, for guaranteeing part quality, can only adopt the method for substep or increase operation to solve, but cause whole processing process long, take the equipment time many, time-consuming, be unfavorable for that formation batch production and the performance of enterprises improve.
Utility model content
The purpose of this utility model is in order to overcome deficiency of the prior art, thereby proposes the soft punch Compound Forming of Bulging of a kind of rigidity frock.
For achieving the above object, the utility model adopts following technical scheme:
The soft punch Compound Forming of Bulging of a kind of rigidity frock, is comprised of die shoe, the first screw, guide pillar, upper cavity die, little guide pin bushing, guide pin bushing, upper bolster, the second screw, axial compression leg, polyurethane rod, the first pin, pressing plate, unloading bolt, spring, blank, the second pin, lower cavity die, ejection block and liftout nail; Lower cavity die is anchored on die shoe with the first screw and the second pin, and head part device liftout nail and ejection block are equipped with in die bottom; Blank is located between axial compression leg and ejection block; Polyurethane rod is placed in blank; Between upper bolster and upper cavity die, be provided with pressing plate and spring; Spring top is provided with unloading bolt; Guide pillar one end is located on die shoe, and the other end is by being located at little guide pin bushing on upper cavity die and to be located at guide pin bushing on upper bolster relative.
Adopt the beneficial effect of technique scheme to be:
The utility model is simple in structure, processing ease, and reliable and practical feature, for the part particularly suitable of middle-size and small-size complexity, has good promotional value.
Accompanying drawing explanation
Fig. 1 is the structural representation of the soft flange of the required processing of the utility model;
Fig. 2 is the structural representation of the soft punch Compound Forming of Bulging of the utility model rigidity frock;
In figure: 1-die shoe, 2-the first screw, 3-guide pillar, 4-upper cavity die, the little guide pin bushing of 5-, 6-guide pin bushing, 7-upper bolster, 8-the second screw, the axial compression leg of 9-, 10-polyurethane rod, 11-the first pin, 12-pressing plate, 13-unloading bolt, 14-spring, 15-blank, 16-the second pin, 17-lower cavity die, 18-ejection block, 19-liftout nail.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, the processing technology of the soft flange part of the required processing of the utility model is: lower materials in the tube φ 48 → face work, guarantees that blank height is that 42 → boss bulging (bulging die, 200KN forcing press) → car both ends of the surface are to figure paper size, technological requirement.
As shown in Figure 2, the soft punch Compound Forming of Bulging of a kind of rigidity frock, is comprised of die shoe 1, the first screw 2, guide pillar 3, upper cavity die 4, little guide pin bushing 5, guide pin bushing 6, upper bolster 7, the second screw 8, axial compression leg 9, polyurethane rod 10, the first pin 11, pressing plate 12, unloading bolt 13, spring 14, blank 15, the second pin 16, lower cavity die 17, ejection block 18 and liftout nail 19; Lower cavity die 17 use the first screws 2 and the second pin 16 are anchored on die shoe 1, and head part device liftout nail 19 and ejection block 18 are equipped with in die bottom; Blank 15 is located between axial compression leg 9 and ejection block 18; Polyurethane rod 10 is placed in blank 15; Between upper bolster 7 and upper cavity die 4, be provided with pressing plate 12 and spring 14; Spring 14 tops are provided with unloading bolt 13; Guide pillar 3 one end are located on die shoe 1, and the other end is by being located at little guide pin bushing 5 on upper cavity die 4 and to be located at guide pin bushing 6 on upper bolster 7 relative.
