Description
Technical field
The utility model relates to a kind of metallic material testing machine structure, especially relates to a kind of combined metal material bending test head.
Background technology
Bending resistance is one of important indicator of some metal materials, and bending resistance is under certain pulling force, and the number of bends of test button defines, and number of bends is more, and bending resistance is better.Chinese patent discloses a kind of metal material bending performance tester (Authorization Notice No.: CN203275185U), it comprises pedestal and is arranged on the platform on pedestal, platform is provided with supporting seat, cylinder is provided with above supporting seat, the both sides of supporting seat are provided with the column for supporting cylinder, the below of Telescopic-cylinder end is provided with the slide block for sliding on column, the below of slide block be provided with supporting seat with the use of pressure head, platform is provided with limit detection device, limit detection device comprises Programmable Logic Controller and the support bar being symmetricly set on slide block both sides and being connected with platform, support bar is provided with high spacing detector switch and low spacing detector switch, high spacing detector switch is connected with the signal input part of Programmable Logic Controller with the low signal output part of spacing detector switch, and the signal output part of Programmable Logic Controller is connected with the input end of the air valve of control cylinder action, the end of pressure head is circular arc, the long 1-15cm of pressure head, and pressure head is cylindrical.But this testing machine in order to the demand of different metal material when doing bending test, needs the pressure head preparing many different-diameter specifications, will change pressure head with not only wasting time and energy, also waste a large amount of materials, add production cost.
Utility model content
The utility model is to provide a kind of combined metal material bending test head, it mainly solves testing machine existing for prior art when doing bending test in order to the demand of different metal material, need the pressure head preparing many different-diameter specifications, pressure head will be changed with not only wasting time and energy, also waste a large amount of materials, add the technical matters of production cost etc.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A kind of combined metal material bending test head of the present utility model, comprise depression bar and basic pressure head, the end face of described basic pressure head is circular arc, the outer cover of basis pressure head is connected to the combination cover pressure head of more than 1, the combination cover pressure head parcel being positioned at outside is positioned at the combination cover pressure head of inner side or whole outside surfaces of basic pressure head, the diameter d of outermost combination cover pressure head
i=d
0+ 2 × (L
1+ L
2+ ... + L
i), wherein d
0based on the diameter of pressure head, L
iit is the radial thickness of i-th combination cover pressure head.The utility model only need prepare a minute quantity even test original base pressure head, the combination cover pressure head making different-diameter specification again on basic pressure head just can meet the testing requirements of different materials substantially, original base pressure head is changed without the need to wasting time and energy when carrying out bending test to different materials, directly change combination cover pressure head just passable, not only save a large amount of materials, also substantially increase test efficiency simultaneously.The different combination cover pressure head of diameter can be socketed on basic pressure head successively according to diameter is ascending, thus adapts to the bending test of different metal material.
As preferably, the diameter d of described basic pressure head
0be more than or equal to 30mm, the radial thickness L of combination cover pressure head
ibe more than or equal to 5mm.Like this can proof strength, the reliability of test figure can be increased again.
Therefore, the utility model overlaps pressure heads in multiple combinations that original basic pressure head outside socket diameter is different, thus the combination cover pressure head of different size can be installed additional according to the testing requirements of different metal material, meet the demand of test, save a large amount of materials, improve test efficiency, simple and reasonable for structure.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Parts, position and numbering in figure: depression bar 1, basic pressure head 2, combination cover pressure head 3.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of combined metal material bending test head of this example, as Fig. 1, comprise depression bar 1 and basic pressure head 2, the end face of basis pressure head 2 is circular arc, the outer cover of basis pressure head is connected to 2 combination cover pressure heads 3, the combination cover pressure head parcel being positioned at outside is positioned at the combination cover pressure head of inner side or whole outside surfaces of basic pressure head, the diameter d of basic pressure head
0for 30mm, the radial thickness L of first combination cover pressure head
1for 6mm, the radial thickness L of second combination cover pressure head
1for 8mm, the therefore diameter d of outermost combination cover pressure head
2=d
0+ 2 × (L
1+ L
2)=58mm.
During use, by depression bar 1, the utility model is encased in Apparatus for Bending at low-temp, according to the requirement of metal material, basic pressure head 2 is loaded onto corresponding two combination cover pressure heads 3.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed among the scope of the claims of the present utility model.
