Abstract
Provided is a mold mechanism of a sample for shearing strength of a sealant. The mold mechanism comprises a lower mold base, a lower mold pressing plate device is fixed on the lower mold base, an upper mold pressure head device matched with the lower mold pressing plate device is arranged above the lower mold pressing plate device, the lower mold base is provided with a sliding seat, a side face of the sliding seat is provided with a vertical guide rail, and a pressing plate on the lower mold pressing plate device is matched with the guide rail. According to the mold mechanism, the H-shaped sample is firmly fixed on a clamp according to a screw principle, avoids the problem of existence of gaps on the clamp, guarantees verticality of stress by means of the rail, and is suitable for tests for the shearing strength in the sealant industry.
Description
Technical field
The utility model belongs to a kind of shearing clamp, relates in particular to a kind of sample mould mechanism of shear resistance of fluid sealant.
Background technology
Stipulate in the GB7124-86 adhesive tensile shear strength assay method: the mensuration of the adhesive tensile shear strength of metal to metal overlap joint at room temperature, this test method is mainly used in the high strength adhesive, and lap joint place glue-line is very thin, for fluid sealant, the method is rigorous not, bonding, cutting performance that can not omnibearing investigation glue.Provide a kind of shearing clamp in the patent No. in the Chinese patent of " 201020568909 ", wherein mainly formed by mold device, a bottom die device.In use, first the mold device is fixed on the puller system, then uses bottom die device that the test piece of " worker " type is fixed on the puller system, use at last lower shaft and mould is connected on the puller system it is tested.Its weak point is that test well is not fixed on the test piece of " worker " type on the anchor clamps, has certain gap; Because what the gap can be pure can not guarantee well when drawing or pressing that " worker " type sample is subject to is a vertical force.And, utilize self vertically do experiment of puller system doing experiment, need to transfer the stressed perpendicularity of puller system.
The utility model content
Problem to be solved in the utility model provides a kind of sample mould mechanism that can guarantee stressed perpendicularity and reduce the shear resistance of the fluid sealant in gap on the anchor clamps.
In order to solve the problems of the technologies described above by the following technical solutions: a kind of sample mould mechanism of shear resistance of fluid sealant, comprise the bed die base, be fixed with the bed die presser device on the bed die base, bed die presser device top is provided with the mold indenter device that matches with it, on the bed die base sliding seat is set, the sliding seat side is provided with the guide rail of vertical direction, and bed die presser device top board matches with guide rail.
Sliding seat is connected on the bed die base by rotary seat.
The sliding seat of four groups of symmetries is set on the bed die base, and four groups of sliding seats are cruciform arranges, and is respectively equipped with the bed die presser device on each sliding seat, has four groups of bed die presser devices.
The utility model is the designed mould of assay method according to the shear resistance of the fluid sealant of defined among the Europe superscript ETAG002, compare with the method for stipulating among the GB7124-86 and to have following remarkable advantage and progress: " worker " type test piece that utilizes the method for testing of defined among the ETAG002 to make, both can make bonding " worker " type test piece of metal-on-metal, also can make bonding " worker " the type test piece of metal and glassy phase and make glass and " worker " type test piece that glassy phase is bonding, not only investigated test piece adhesive property between the metallized metal in the shear tension process, also investigated and the adhesive property of glass and the adhesive property of glass and glass, can simulate more really like this fluid sealant shear bond performance in the use procedure on engineering.The utility model utilizes the principle of screw firmly " worker " type sample to be fixed on the anchor clamps, has avoided " worker " type sample to have gapped problem at anchor clamps, utilizes track to guarantee stressed perpendicularity.The utility model goes for the test of the shear resistance of fluid sealant industry.
