Abstract
This utility model provides a kind of gasket compression rebound test device, including tensile testing machine and the pressure head that coordinates with tensile testing machine, below testing machine entablature, upper mounting plate is installed, pressure head is arranged on below upper mounting plate by bolt, the lower platform placing experiment pad is installed on testing machine sill, pressure head is corresponding with lower platform position, uses electronic universal tensile testing machine to complete gasket compression rebound test, has obtained the force deformation curve in gasket compression springback process.
Description
Technical field
This utility model belongs to pad field tests, is specifically related to a kind of gasket compression rebound test device.
Background technology
The existing standard GB/T of gasket compression rebound test/T 12622-2008 " pipe flange gasket compression rate and
Rebound degree test method " in give special test device, this device uses sliding weight, lever-loading, logical
Cross mobile sliding weight and change load, process of the test whole process Non-follow control, process of the test does not use force transducer,
Therefore can only obtain the result of compression ratio and rebound degree, result of the test is used merely to as whether pad quality closes
The acceptance basis of lattice.
Along with the raising of Product Precision, when product hermeticity can be carried out finite element analysis, need to use pad
Power-deformation curve during sheet compression rebound and real time data, existing apparatus cannot obtain data above.Mirror
In this, invention uses electronic universal tensile testing machine to complete gasket compression rebound test device with acquisition power-deformation
Curve imperative.
Utility model content
The purpose of this utility model is to overcome prior art defect, it is provided that a kind of gasket compression rebound test dress
Put, use electronic universal tensile testing machine to complete gasket compression rebound test, obtained gasket compression resilience
Power-deformation curve in journey.
For reaching above-mentioned purpose, this utility model adopts the following technical scheme that
A kind of gasket compression rebound test device, including tensile testing machine and the pressure head that coordinates with tensile testing machine,
Being provided with upper mounting plate below testing machine entablature, pressure head is arranged on below upper mounting plate by bolt, under testing machine
Being provided with the lower platform placing experiment pad on crossbeam, pressure head is corresponding with lower platform position.
Further, described pressure head is inverted cone-shaped structure, and pressure head end arranges cylinder and presents a theatrical performance as the last item on a programme.
Further, the cylinder of described pressure head end presents a theatrical performance as the last item on a programme diameter less than the diameter testing pad.
Further, described pressure head is arranged on below upper mounting plate by equally distributed four bolts.
Further, described upper mounting plate and lower platform are cylindrical bar.
Gasket compression rebound test device of the present utility model, joins including tensile testing machine with tensile testing machine
The pressure head closed, uses electronic universal tensile testing machine to complete gasket compression rebound test, has obtained gasket compression
Power-deformation curve in springback process.
This utility model also has the advantages that
(1) quality control to pad can be realized；
(2) obtain the power-deformation curve in gasket compression springback process, improve the precision of finite element analysis；
(3) use general tensile testing machine to replace special equipment, save the cost of equipment purchasing.
Accompanying drawing explanation
Fig. 1 a is the front view of pressure head；Fig. 1 b is the upward view of pressure head；
Fig. 2 uses this utility model to carry out the operating diagram tested；
In figure: 1-testing machine entablature；2-bolt；3-upper mounting plate；4-pressure head；5-tests pad；Put down under 6-
Platform；7-testing machine sill.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail:
Gasket compression rebound test device as shown in Fig. 1 a, Fig. 1 b and Fig. 2, including tensile testing machine and with draw
The pressure head 4 that force tester coordinates, is provided with upper mounting plate 3 below testing machine entablature 1, pressure head 4 passes through bolt
2 are arranged on below upper mounting plate 3, and testing machine sill 7 is provided with the lower platform 6 placing experiment pad 5,
Pressure head 4 is corresponding with lower platform 6 position.
Further, described pressure head 4 is inverted cone-shaped structure, and pressure head 4 end arranges cylinder and presents a theatrical performance as the last item on a programme.Pressure head 4
The cylinder of end presents a theatrical performance as the last item on a programme diameter less than the diameter testing pad 5.
Further, described pressure head 4 is arranged on below upper mounting plate 3 by equally distributed four bolts 2.On
Platform 3 and lower platform 6 are cylindrical bar.
As in figure 2 it is shown, work process is as follows:
(1) pressure head is installed on tensile testing machine entablature；(2) pulling force of gasket compression springback process is opened
Testing machine program；(3) do not put into pad, run a program, it is thus achieved that reflection tensile testing machine stiffness by itself
Power-deformation curve；(4) put into pad, run a program, it is thus achieved that power-deformation curve；(5) number is used
According to processing software, the curve of the 4th step deducts the 3rd step curve, obtains gasket compression resilience force-deformation curve.
Above content is further detailed description of the utility model, it is impossible to assert of the present utility model
Detailed description of the invention is only limitted to this, for this utility model person of an ordinary skill in the technical field,
Without departing from the concept of the premise utility, it is also possible to make some simple deduction or replace, all answer
Utility model protection scope is determined by the claims submitted to when being considered as belonging to this utility model.
