This kind of size adjustable tensile testing machine uses crooked pressure head, including installing the metalwork on tensile testing machine, metalwork lower extreme swing joint has a cylindric working of plastics, offer on the working of plastics and be used for the metalwork lower extreme to inlay the recess of establishing, metalwork and working of plastics vertical distribution, working of plastics surface mounting has the locking device with metalwork and working of plastics locking. The utility model discloses simple structure, reasonable in design, it is easy and simple to handle, suit rigid plastic spare on the metalwork, because the working of plastics cuts more easily and drills, it is more convenient that the preparation is got up, labour saving and time saving, change not unidimensional working of plastics, be applicable to various different standard size test requirement, enlarge application range, be equipped with spring locking structure, carry the connection performance of high metal spare and working of plastics.
Description
Technical field
This utility model is related to metal material mechanics performance test apparatus technical field, especially a kind of drawing of size adjustable
Force tester bending pressure head.
Background technology
Bend test is mainly used to determine the ability that metal material bears bending ductility deformation, is that quality control and engineering set
The important references index of meter.At present flat-bend test adopts bikini bending method mostly, will sample centering be placed on two
In symmetrical support roller, adopt at its span center line bending pressure head imposed load and keep which with constant rate of speed bend, directly
Predetermined angular is reached to sample deformation, then detect that material surface has flawless, to determine its bending property.
In process of the test, bending pressure head is selected generally according to product technology condition, its size and sample thickness with
And specific performance is relevant, i.e., different materials correspond to different bending pressure heads.The bending pressure head component that Apparatus for Bending at low-temp is equipped with present
It is made up of pressure head bearing, bending pressure head, baffle plate and locking nut etc., bending pressure head is fixed on bearing by two locking nuts
On.The locking nut and baffle plate of loose ends when replaceable pressure head is needed, is answered first, loads onto new pressure head after pulling down old pressure head, weight
The locking nut and baffle plate at two ends on new clothes, this traditional pressure head substitute mode are relatively complicated, have a strong impact on work efficiency.
The indenter size that conventional indenter size is mentioned in having used metal casting, but some standards due to being of little use,
Using metal casting waste of resource, waste time and energy.
Utility model content
The technical problems to be solved in the utility model is：Overcome the deficiency in prior art, there is provided a kind of simple structure, fit
The tensile testing machine of the size adjustable required for various various criterion dimension tests bending pressure head.
This utility model solves the technical scheme adopted by its technical problem：A kind of tensile testing machine of size adjustable is used
Bending pressure head, including the metalwork being installed on tensile testing machine, metalwork lower end is connected with cylindric working of plastics, described
The groove being embedded for metalwork lower end, metalwork and working of plastics vertical distribution is offered on working of plastics；The plastic part surface
The locking device that metalwork and working of plastics are locked is installed.
Further, described locking device includes being installed on the bolt block of plastic part surface and is installed on metalwork side
The annulus of wall, is connected with spring between bolt block and annulus, spring one end is fixed on bolt block, and the spring other end is connected with extension
Hook, hook are flexibly connected with annulus.When needing to change working of plastics, link up with from annulus；After working of plastics is more finished changing,
Hook annulus.
Further, described recess sidewall is bonded with the rubber blanket for preventing metalwork from deviating from.Improve metalwork and plastics
The tightness of part.
The beneficial effects of the utility model are：This utility model simple structure, it is reasonable in design, it is easy to operate, in metalwork
Upper suit rigid plastics part, because working of plastics is easier to cut and drills, makes more convenient, time saving and energy saving；Change not
With the working of plastics of size, it is adaptable to various various criterion dimension tests requirements, expand use range；Spring locking mechanism is provided with,
Improve the switching performance of metalwork and working of plastics.
