Description
Technical field
The utility model relates to a kind of testing machine, particularly discloses a kind of metal tensile test machine self-lubricating steel plated guideway plate, and the self-lubricating steel plated guideway plate also can be applicable on the various universal testing machines.
Background technology
Standard GB/T228-2002 stipulates metal material tensile test at room temperature method, stretching test method must be deferred to the regulation of GB/T228-2002 standard, parameters such as the displacement of metal material tensile sample, fracture breaking elongation and peak load, all must reach setting, the stretching quality of metal material is the conformance with standard requirement, otherwise invalidate the test.
At present metal material is stretched and detect test method employing dedicated tensile test machine, according to the characteristics of sample, special design specialized chuck is shown in accompanying drawing one.Clamping by: jaw, oil cylinder, piston, guiding pressing plate, liner plate, steel plated guideway plate, fixture block etc. are formed, and structure is the left-right symmetric form.Fixture block is connected on the liner plate by dovetail, and a sliding friction surface is arranged between liner plate and the steel plated guideway plate, and liner plate can constituted in the space and slided by steel plated guideway plate and guiding pressing plate.When piston upwards promotes liner plate, two fixture blocks when the y direction moves also respectively to+x and-the x direction moves, along with the increase of test pulling force, fixture block also increases the clamping force of sample, thereby makes sample be locked automatically, can not be drawn out.
This method to the shortcoming of large-tonnage (200 tons of testing machine pulling force) is: because the sample tensile force is bigger, for guaranteeing that sample can be clamped, the jaw angle must be enough little, but, the α angle is too small, then liner plate can cause self-locking easily because of friction force, make the off-test rear lining plate not return, the sample after breaking also is not easy to be removed and, and reason is because the slip between the planar kinematic pair that test pulling force big (maximum 200 tons) and liner plate and steel plated guideway plate are formed produces powerful extrusion friction, lubricating oil film is destroyed between the rubbing surface, thereby lubricate not, friction factor increases, and liner plate produces and creeps, increase along with access times, friction factor can be increasing, arrived certain degree, and sample also can produce displacement (being that what is called is fallen power), if increase the α angle, holding force again can be not enough, thereby make sample (being that power is fallen in the displacement) test figure of skidding in fixture block just inaccurate easily, makes invalidate the test, integrate and see, can reduce the problem of seven aspects:
1, be subjected to powerful extrusion friction between the rubbing surface of steel plated guideway plate and liner plate, oil film is destroyed, no oil film;
2, the friction slip surface strength is not enough, and the surface is destroyed, and the plucking situation is arranged;
3, edge steel plate step insufficient strength is often broken;
4, adding lubricating oil operates loaded down with trivial details, very inconvenient;
5, generation is creeped, and sound is arranged;
6, frictional resistance increases, and causes the sample slippage, produces power;
7, test figure is inaccurate, and is invalid until test figure.
Summary of the invention
The purpose of this utility model is to overcome defective of the prior art, through comprehensive comprehensive analysis and research, now provides a kind of high strength low-friction coefficient, and has the metal tensile test machine self-lubricating steel plated guideway plate of stronger compressive property.The solid lubricant that the prescription of employing new technology is made is designed to arrange hole orderly, that size is suitable especially on the steel guideway board plane, and is embedded in the kollag with unique self-lubricating property in the hole.This steel plated guideway plate combines the characteristic of metal material, selects the high-quality high carbon steel sheet for use and has the combination of the inlaid solid lubrication agent material of special formulation.The conventional method and the limitation of sliding friction dependence film lubrication between general face and the face have been broken through, and the self-lubricating steel plated guideway plate of making in conjunction with advanced technological method for processing, being particularly suitable for testing machine stretches when clamping, be subjected to powerful extruding sliding friction between liner plate and steel plated guideway plate face and the face, the occasion that the ruined special operation condition of oil film, heavily loaded to-and-fro movement oil film are difficult to form can be worked under the oil-free lubricatoin condition for a long time.Characteristics intensity height, self-lubricating can not bitten between the rubbing surface, wear-resistant and extremely low friction factor.
The utility model is achieved in that a kind of metal tensile test machine self-lubricating steel plated guideway plate, testing machine jaw both sides symmetry is passed through steel plated guideway plate, pressing plate, fixture block clamping round specimen, the surface of contact of steel plated guideway plate and pressing plate is that strong extrusion friction face is called the A face, it is characterized in that: the A face of steel plated guideway plate is provided with 30-50 and arranges orderly blind hole, the aperture of blind hole is at Φ 3mm～Φ 5mm, the degree of depth is at 3mm～5mm, filling solid lubricant in the blind hole, the steel guideway board substrate is through mid frequency induction hardening thermal treatment, matrix hardness 35～39HRC, A plane hardness 58～62HRC, A plane rigidity layer degree of depth 3mm～4mm.
The interior filling solid lubricant of blind hole is formulated by graphite, molybdenum disulfide and teflon on the described steel plated guideway plate A plane.
The inclination angle of described steel plated guideway plate clamping round specimen is 15 °.
The long 170mm of described steel plated guideway plate, wide 150mm, the C face that the A face is relative are that roughness only is 3.2 high coefficient of friction surface.
The beneficial effects of the utility model are: 1, solved for a long time the sample power problem that stretches, improved the technology content of testing machine; 2, solved the puzzlement of adding the lubricant inconvenience for a long time; 3, the depth layer that has solved the hardness of steel plated guideway plate has improved the intensity of guide rail plate; 4, reduce the plucking phenomenon of steel plated guideway plate, prolonged the serviceable life of guide rail plate; 5, do not need to add lubricant; 6, improved social benefit, saved the quality lubricant expense that prior art must be added, this quality lubricant is external import.
