Description
[technical field]
The utility model is related to detection device technical field, specifically a kind of to be used to simulate the impact examination by fire experiment
Experiment device.
[background technology]
It is the important component of modern Fire Science by fiery appraisal of equipment technology, its technological core intension is by analysis
Influence the various factors of fire and test the data after fire occurs and fire generation history, process and the loss shape caused
Condition, binding test data carry out a safe and scientific skill of comprehensive analysis to the safe condition by fiery equipment, performance loss situation
Art.
China's petrochemical industry moderate heat pressure pipeline and equipment there is no fast and accurately safety evaluation method, are by fire detection
Based on factors such as the degradation by fiery equipment and materials, surrounding destructiveness, need to early stage to by fiery equipment carry out mode of appearance,
The correlation of performance degradation and microstructure, delimited by pressure ignition container and pipeline by the torrid zone and difference is by the pressure in the torrid zone
On the basis of the researchs such as the verification scheme formulation of force container and pipeline, it is determined that by the evaluation method and criterion of fiery material, and set up
Perfect field test method.Temper embrittlement is a kind of metallographic change, and outward appearance is difficult to find, the damage caused due to temper embrittlement
Catastrophic brittle fracture can be caused, metallographic change can be by being confirmed by the impact test after fire.
[utility model content]
The utility model is the technical problem that can not be from outward appearance progress for metal material temper embrittlement, according to gold
Belong to characteristic by fiery equipment simple in construction, easy to operate is used to simulate the impact test apparatus by fire experiment there is provided a kind of.
To achieve these goals, design is a kind of is used to simulate the impact test apparatus by fire experiment, including base, guiding
Positioning table is provided with the middle part of post and beater mechanism, described base, two leads be arrangeding in parallel are erect in positioning table both sides respectively,
A structure of an essay for two leads has beater mechanism, and described beater mechanism is made up of hanging deck, back timber and impact bar, and back timber is fixed on guiding
Column top, in back timber midline through there is impact bar, back timber lower section is provided with hanging deck in parallel, hanging deck and is placed with counterweight
Block.
Guiding post part between described hanging deck and back timber is cased with spring.
Described test block is positioned in positioning table, and described positioning table and impact bar are located on same vertical line.
The utility model compared with the existing technology, the advantage is that：This experimental rig carries shock machine moving up and down
Balancing weight on structure, hanging deck can be according to different tests demand adjustable weight, and impact bar is after stress to the test sample in positioning table
Product carry out impact test, and process of the test simply, conveniently, stably, is observed by fiery materials microstructure performance development deeper into ground.
[brief description of the drawings]
Fig. 1 is structural representation of the present utility model；
In figure：1. the spring of 7. balancing weight of base 2. lead, 3. positioning table, 4. hanging deck, 5. back timber, 6. impact bar 8..
[embodiment]
The utility model is described in further detail below in conjunction with the accompanying drawings, the structure and principle of this device people professional to this
For be very clear.It should be appreciated that specific embodiment described herein is only to explain the utility model, and without
In restriction the utility model.
Embodiment 1
Impact test apparatus includes base, lead and beater mechanism, sees and positioning table, positioning table are provided with the middle part of Fig. 1, base
Two leads be arrangeding in parallel are erect in both sides respectively, and a structure of an essay for two leads has beater mechanism, and beater mechanism is by hanging deck, back timber
And impact bar is constituted, back timber is fixed at the top of lead, and in back timber midline through there is impact bar, back timber lower section is provided with flat with it
Balancing weight is placed with capable hanging deck, hanging deck, the guiding post part between hanging deck and back timber is cased with spring.
During experiment, test block is positioned in positioning table, and ensures being located on same vertical line of positioning table and impact bar, to make
When must drive the impact bar to move downward, test block can just under the pressure of balancing weight, the number and weight energy of balancing weight according to
Increase and decrease is needed, balancing weight, and hand hoisting beater mechanism are taken out after experiment, test block is taken out from positioning table, whether is detection test block
Deform upon, so that the metallographic intensity of variation to determine metal material.
