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.Chuck 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 lubricated face 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, 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, 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 following five aspects:
1, the intensity of steel plated guideway plate step,
2, steel plated guideway plate A face low-friction coefficient,
3, steel plated guideway plate C face great friction coefficient,
4, lubricating film is destroyed easily, and the destroyed back plane of lubricating film slides to be easy to generate and creeps,
5, sample skids.
Summary of the invention
The objective of the invention is to disclose the manufacture method of 200 tons of tester for metal tension test steel plated guideway plates of a kind of pulling force, make steel plated guideway plate overcome shortcoming of the prior art, realize improving the hardness on guide rail plate surface, make it not produce interlock, to matrix hardness certain requirement must be arranged simultaneously, the step that guarantees the guide rail plate can not fractureed, and increases the service life.
The present invention is achieved like this:
The manufacture method of 200 tons of tester for metal tension test steel plated guideway plates of pulling force, technological process comprises that material selects 45 steel, forging, annealing, rough cut processing, normalizing treatment, smart cut, heat-treatment quenching, lonneal, grinding, sandblast, phosphatization is handled, it is characterized in that: heat-treatment quenching, lonneal, increase chemical treating process after the grinding, described chemical treating process cleans at least twice for the steel plated guideway plate decontamination, 150 ℃ of oven dry of low temperature, workpiece advances stove, add catalyzer in the stove in advance, progressively be warming up to 550 ℃ from 60 ℃, be incubated 14-16 hour, become the gas shape to decompose for making catalyzer, take out the workpiece natural air cooling.
The catalyzer that adds in the described heat-treatment furnace is by nitrogen, and the percentage by weight of each element of catalyzer that carbon, rare earth, sulphur are formed is: nitrogen 20%, carbon 20%, rare earth 20%, sulphur 40%.
The invention has the beneficial effects as follows:
Dosed this procedure of chemical treatment, this procedure can improve the hardness on guide rail plate surface, makes it not produce interlock, having guaranteed that sample is clamped can not produce power, matrix has needed hardness simultaneously, and intensity improves, and has guaranteed that the step of guide rail plate can not fractureed, and the elementary sulfur that adds, make part have the characteristic of self-lubricating again, we are not added or apply oil seldom, the steel plated guideway plate surface just is not easy dirty like this, part is indeformable after treatment, has guaranteed its serviceable life.
Embodiment
The heat treatment process of whole steel plated guideway plate: material selection → forging → annealing → rough cut processing → normalizing treatment → smart cut → heat-treatment quenching → lonneal → grinding → chemical treatment → sandblast → phosphatization is handled
Common heat treatment process is as follows: material selection → forging → annealing → rough cut processing → normalizing treatment → smart cut → heat-treatment quenching → lonneal → grinding → sandblast → phosphatization is handled,
Common heat treatment (the back tempering of quenching) and changes in material properties situation tabulation one are in following:
Table one
| Material | Quench | Lonneal | Hardness | Explanation |
| Temperature, cooling medium | Temperature, cooling medium | |||
| 45 steel | 840-860 ℃ of water | 180-220℃ /1.5h | Whole 45-50HRC | After the common heat treatment, material presents the hardness height, crisp, as to fracture easily phenomenon |
Reach the changes in material properties situation after the chemical treatment of the present invention and see Table two
