Description
Technical field
The present invention relates to automotive sheet forming property determination techniques fields more particularly to one kind can disposably complete gold
The device and method of the punching of metal thin plate sample, reaming.
Background technique
Sheet metal after shearing or punching can be had damage in cutting part to be generated with processing hardening, is struck out subsequent
When the stretcher strains such as shape especially flange, these positions can prematurely crack and cause to destroy, especially for high-strength steel
For duralumin, hard alumin ium alloy, this situation is particularly acute.Hole expansion test is the thin plate formed to examine the flange performance of plate
Test process.Plate is pressed on blank holder when test, the sample after punching is pressed into cavity plate with punch-pin, makes sample centre bore
Expand, until constriction or crackle occurs in aperture edge, test result is used to evaluate the flanging forming performance of sheet metal.
Newest hole expansion test standard GB 24524-2009/ISO 16630:2009 " metal sheet and strip reaming
Test method " regulation, the sample of hole expansion test carries out hole expansion test again after being first punched out, therefore uses existing experimental rig
It just needs to prepare two mold of punching die and hole expansion die, and needs to re-start experimental rig tune in more mold exchange
School, to cause complicated for operation, test efficiency is low.
Patent No. CN200910054902.2 and CN200420114955.1 Chinese patent realizes punching and reaming mould
Tool is applied in combination, but structure is complicated, cost is high, Operation and Maintenance is troublesome for mold, be not suitable for existing experimental rig into
Row transformation；And its hole-expansion punch uses cylinder punch-pin, to play a supportive role in punching to plate；And it is tried in new reaming
In the quasi- GB 24524-2009/ISO 16630:2009 of standard inspection " metal sheet and strip hole expansion test method ", define
Punch should use conical punch；Therefore, it is necessary to develop one kind to can satisfy newest hole expansion test standard and structure letter
