Description
Technical field
The utility model belongs to high-strength steel sheet material shaping field, relates in particular to the two-way Olsen test particular manufacturing craft of subsidiary adjustable positioning system.
Background technology
Olsen test (Olsen test) is the test method of evaluating sheet metal formability.During test, with bulb punch is pushed down periphery sheet metal by die and blank holder, head into die, form hemisphere bulge until crackle appears in bulge top.Test with hard steel ball or hemisphere punch, metal blank is pressed into the die of internal diameter 25mm, radius of corner 0.6mm, slab edge compresses between die and blank holder 3.For preventing that edge metal from flowing in die, plate size should be enough large.During test, metal blank is pushed up into hemisphere bulge by punch.Punch compression distance when getting bulge top generation constriction or having crackle to occur, as test index, is called Olsen Erichsen number or I: value, YimmWei unit.Two-way Olsen testing laboratory also can be used to carry out high-strength galvanizing plate zinc layer adhesion and evaluates its evaluation method and sample upset is tested for the second time after an Olsen test for carrying out, and finally by evaluating Zinc Scaling degree, evaluates the adhesion of zinc layer.
The locating device > > (ZL200920137829.0) of < < circular blank discloses a kind of auxiliary locating tool of machine die processing, a kind of locating device of circular blank is specifically provided, this locating device comprises three spacers, regulating ring and locating rings, by turning axle, be fixed on described retainer plate, utilize spacer to position sample.This locator meams is suitable for the location of low-intensity steel plate, cannot effectively limit the side force of plow-steel in two-way olsen test.
Utility model content
The purpose of this utility model is to overcome the problems referred to above and is provided for the two-way Olsen test mould of the subsidiary adjustable positioning system of the two-way Olsen zinc of a kind of high-strength steel layer adhesion testing experiment with deficiency.
A kind of two-way Olsen test of high-strength steel test mould of subsidiary positioning system, comprise the drift matching with forming test machine, upper blank holder and lower blank holder, locating ring is positioned on lower blank holder by screw, locating ring ring arranged outside module slot, locating piece is set in module slot, pilot hole is set on locating piece; Locating piece and lower blank holder and locating ring upper surface be at same plane, and location briquetting is pressed in spacer on the upper surface of locating piece and lower blank holder by screw, and register pin is inserted to corresponding pilot hole, by the fixing sample of stationary positioned sheet.
Pilot hole quantity be two and more than.
Sample is placed on lower blank holder, and regulates compressing tablet position, compressing tablet and sample are not overlapped, and compressing tablet is fully contacted with sample.
Effect service test and make upper and lower blank holder closed, and check locating ring position, guarantee that locating ring and location compressing tablet do not cause interference to test test.Start to test.
The present invention is easy and simple to handle, only need on electronic universal sheet material forming testing machine, upper and lower blank holder and detent mechanism be fixed, and semi-cylindrical drift is positioned on testing machine master cylinder drift, before each test, choose rational adjustable locating block and adjust compressing tablet position, location, utilize testing machine accurately to control pressure-pad-force, can realize accurate two-way Olsen test.

1-drift in figure, the upper blank holder of 2-, blank holder under 3-, 4-module slot, 5-screw, 6-locating piece, 7-register pin, 8-locates briquetting, 9-spacer, 10-pilot hole, 11-locating ring.
Embodiment
A kind of two-way Olsen test mould of high-strength steel of subsidiary positioning system, comprise the drift 1 matching with forming test machine, upper blank holder 2 and lower blank holder 3, locating ring 11 is positioned on lower blank holder 3 by screw 5, locating ring 11 ring arranged outside module slots 4, the interior locating piece 6 that arranges of module slot 4, arranges pilot hole 10 on locating piece 6; Mounted locating piece 6 and lower blank holder) and locating ring 11 upper surfaces at same plane, location briquetting 8 is pressed in spacer 9 on the upper surface of locating piece 6 and lower blank holder 3 by screw 5, register pin 7 is inserted to corresponding pilot hole 10, by the fixing sample of stationary positioned sheet 9.
Pilot hole 10 quantity be two and more than.
Sample is placed on lower blank holder, and regulates compressing tablet position, compressing tablet and sample are not overlapped, and compressing tablet is fully contacted with sample.
This two-way olsen test mould has utilized the systematic study of universal plate forming test machine different plates, different olsen punching strokes and the evaluation of different flanging pressure to high-strength steel galvanized sheet Zinc Scaling situation, the technical parameter providing the foundation for the formulation of the shaping technique for applying of high strength steel plate.
