Description
Technical field
The utility model belongs to the sheet metal detection range, relates in particular to a kind of plate flange characteristic detection device.
Background technology
Flange is the part with metal plate blank or semi-manufacture workpiece, makes its inner flange partly become greatly, become the press-processing method that the vertical edge edge is arranged along its certain outline line.Usually the shape according to formation of parts can be divided into a lot of types, as circular hole flange, special-shaped hole flanging, opening hole flanging or the like.Exist a large amount of flange features in the automobile panel, all will carry out the flange operation usually after the operations such as in the production run of these parts, process is drawn, deburring.In recent years, for the security that improves automobile with reduce cost, the in use shared ratio of high-strength steel sheet and hot rolling acid-cleaning plate is increasing, but the flange performance of these materials how, which type of mould and technological parameter have influence rule to the flange result, also do not have good methods to carry out research and analysis at present.
State Standard of the People's Republic of China-metal sheet profiled performance and test method-hole expansion test (GB/T 15825.4-2008) have proposed a kind of test method of investigating sheet metal reaming performance.When its principle is test, the sample that the center is had a prefabricated circular hole places between die and the blank holder and compresses, by punch the sample material of its underpart is pressed into die, force prefabricated Circularhole diameter constantly to swell, ftracture until the peritreme part, stop the punch motion, and measure the maximal value and the minimum value in sample aperture, calculate the reaming performance index of hole expansibility as sheet metal with them.In actual use, this standard also is used to check the forming property of the circular hole flange of sheet metal.
The problem of said method is: (1) can only investigate the circular hole flange performance of material; (2) this flange only relates to a kind of stress, i.e. stretch flanging, and the stress that can't investigate compression flange, straight line flange and combine; (3) can not investigate die parameters and part shape the rule that influences to the flange characteristic.
Continuous research and development along with the high-strength steel product, and the case with the alternative cold-reduced sheet of hot rolling acid-cleaning plate that cost pressure causes is more and more, promoting the use of of the relatively poor material of these formabilities, the probability that all makes the manufacture process of bodywork parts produce defective increases greatly, wherein the flange cracking phenomena is also serious day by day, and this progressively becomes high-strength steel sheet and hot rolling acid-cleaning plate bottleneck problem in use.So need a kind of mould that can detect and study sheet material flange performance.
The utility model content
Technical problem to be solved in the utility model has provided a kind of assessment mould of testing plate flange characteristic, concentrate in the mold by stress stretch flanging, compression flange and straight line flange, has good similarity with the flanging forming process of actual part, have the characteristic of adjusting plate flanging process parameter and die parameters preferably, can further investigate the influence rule of parameters such as flange radius, die clearance plate flange height.
A kind of assessment mould of testing plate flange characteristic, comprise die shoe, upper bolster, elevating mechanism, punch, die and flanging mould, described upper bolster links to each other with die shoe by guide pillars and bushes, described punch is fixed on the die shoe, described die is fixed on the upper bolster, described flanging mould links to each other with elevating mechanism, the corresponding end shape of described punch and die is meshing with each other, the cross section of punch corresponding end is made of the tangent straight line of 3 sections circular arcs and 4 and circular arc, arc section and straight-line segment are arranged at interval, middle arc section for protruding, both sides are recessed arc section, be furnished with register pin and chute on the described flanging mould, chute has scale mark on the limit, and positioning sliding block is housed on the chute.
On described die and the horizontal direction that upper bolster links to each other gap adjusting mechanism is housed.
Described gap adjusting mechanism comprises clearance gauge, clearance gauge locating piece and clearance gauge register pin.
The arc section radius that protrudes in the middle of the described punch is 30～60mm.
The utility model concentrates on the stress of stretch flanging, compression flange and straight line flange in one mold, has good similarity with the flanging forming process of actual part.Simultaneously, utilize the structure of punch, die and flanging mould, have the characteristic of adjusting plate flanging process parameter and die parameters preferably, can further investigate the influence rule of parameters such as flange radius, die clearance plate flange height.Can deepen the research of high-strength steel and acid-cleaning plate flange characteristic aspect by the utility model, the flange characteristic of quantitative evaluation high strength steel plate in drawing, help automobile factory to carry out reliable selection, and reduce car stamping parts manufacturing cost, shortening new model construction cycle, to advance the stable use on existing vehicle of automobile factory and new model of high-strength steel and acid-cleaning plate.
