Description
Technical field
The present invention relates to one kind to be used for metal material straight pin shearing test simple frock, belongs to mechanical test technology
Field.
Background technology
The shear strength of metal material refers to the ability that material bears shearing force, and it is vertical with material axis and right to refer to external force
Material is in the strength degree of shear action.Its detect be typically by straight pin load as defined in fixture, it is desirable to support part with
Gap between loading part is no more than 0.15mm, then exerts a force to detect the shear strength of material.
Existing typical two kinds of pins shearing clamp frock, the first conventional brace wherein shown in Fig. 1 is more complicated, by pressing from both sides
The compositions such as tool, cushion block, the guide pillar of packing ring and cutout, the bushing that hardens, cutout.Straight pin is arranged in the bushing that hardens, led to
The load that cutout applies axial direction is crossed, so as to complete shearing test, the fixture is more complicated in manufacture, and consumptive material is more, because hardening
The size of bushing and straight pin are similar, and to keep straight pin breach upward, installation difficulty before experiment, the cylinder being broken after experiment
Pin, which is retained in, to harden in bushing, it is difficult to takes out.
Second of conventional brace shown in Fig. 2 is made up of harden supporting cylinder and the shearing rod that hardens, simple in construction.By straight pin
It is fitted into the supporting cylinder that hardens, by applying the load of axial direction to the shearing rod that hardens, so as to complete shearing test.Because standard provides
Gap between loading part and support accessory is no more than 0.15mm, and therefore, the fixture is in straight pin shearing test, to ensure
The cooperation in gap, the straight pin aperture on cylinder is typically equal with the straight pin of theory, and in practice, straight pin is through overheat
Size is irregular after processing, to realize shearing test, it is necessary to and by external force in straight pin load hole, installation clamping is difficult,
Time-consuming, if what is carried out is two-sided cutting, i.e., both sides are both needed to load straight pin, then time-consuming double, and cylinder can not be completely secured
The breach of pin is upward.
The content of the invention
The purpose of the present invention is for problem present in above-mentioned characteristic shear experiment, there is provided a kind of to dismount simply, more
Change convenient round metal pin shearing test simple frock.
In order to achieve the above object, the present invention adopts the following technical scheme that：
Round metal pin shearing test simple frock, the main plug that includes hardening, cylinder top cover, cylinder lower cover, lock-screw and
Locking nut；The center of cylinder top cover and the cylinder lower cover respectively offers a semicircle orifice, shape when the two is combined
Into an endoporus；The both sides of cylinder top cover and the cylinder lower cover respectively offer a pair of through holes；The plug that hardens is placed in endoporus.
It is using the beneficial effect of above-mentioned technical proposal：
1st, compared with prior art, it is simpler using experiment process of the present invention, it is quick and easy to operate：Round metal pin is placed on
In endoporus among upper lower shell, round metal pin is fixed with locking nut by lock-screw, is reloaded into the core that hardens
For rod in upper lower shell, to hardening, plug applies axial load, unclamps locking nut after experiment, because the hole size of endoporus is closed for two
One formed, after fracture the deformation of sample be not enough to the hole of endoporus to fill up, can be easily removed experiment after straight pin, easily realization
Shearing test, it is this process safety, quick, precisely ensure the breach of straight pin upward, it is easy to operate.
2nd, compared with prior art, the present invention is made using high-strength alloy Steel material, is entered by special thermal treatment technique
After row processing, intensity is high, and the load born is big, is hardly damaged, and durability is good.
3rd, compared with prior art, the present invention only need among sleeve diverse location bore different size size through hole, i.e.,
The shearing test of different straight pins can be met, be not required to re-work sleeve up and down, saved material cost, reduced and be manufactured into
This, improves operating efficiency, simplifies operating process.
