Description
Technical field
The utility model relates to a kind of frock of processing boss bulging part, relates in particular to the frock that a kind of rigidity split-type punch bulging is processed soft flange.
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 is excellent) 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 rubber (or polyurethane rod) the deep enough small gap of 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 a kind of rigidity split-type punch bulging frock.
For achieving the above object, the utility model adopts following technical scheme: a kind of rigidity split-type punch bulging frock, is comprised of upper die and lower die two parts; Part of the lower die is comprised of die shoe, screw A, lower cavity die, distinguish punch, locating piece, unloading bolt, taper pellet, back-moving spring, push pedal, screw B and push rod, and part of the upper die is comprised of upper cavity die, upper bolster, stop pin, die shank and screw C; Lower cavity die is anchored on die shoe with screw A, and the push pedal of head part device and push rod are equipped with in lower cavity die bottom; Die inner conical pellet is with on the fastening die shoe of screw B; Locating piece is actively coupled with unloading bolt and taper pellet; Distinguish punch connects by back-moving spring, and the cannelure on distinguish punch is used for laying back-moving spring, and distinguish punch resets under the effect of back-moving spring; Upper cavity die is anchored on upper bolster with screw C.
The cone angle design of described taper pellet is 40 °.
Described distinguish punch quantity is designed to 12.
The fillet of radius of corner r=(1.5～2) mm is made at the mould lobe edge of described distinguish punch.
Described back-moving spring is a circular disc spring.
Adopt the beneficial effect of technique scheme to be:
Little and the less demanding plate blank bulging of product to dimensional accuracy of the utility model particularly suitable deformation extent, part after bulging, presentation quality is good, the requirement of size conforms pattern, has met the requirement of properties of product, compares with former technique, there is Design of Dies simple, reliable and practical feature, the part particularly suitable for middle-size and small-size complexity, has good promotional value.
