Abstract
The utility model relates to an auxiliary device for a heat and mechanics analogue test machine. The utility model is characterized in that the utility model is composed of a tension-pressure sheath clamp, a pre-pressure clamping seat, pre-pressure threaded rods, pressure springs, and a rotary pressure regulating handle. One end of the tension-pressure sheath clamp is fixed on a force sensor and is integrally connected with a movable clamp head, and the other end is fixed on the pre-pressure clamping seat; the whole auxiliary device is fixed between the machine body and the movable clamp head by the pre-pressure clamping seat through threaded rods on the upper and the lower ends, the pressure springs respectively sheathed in the threaded rods and the rotary pressure regulating handle; the interior of the tension-pressure sheath clamp is provided with a through cavity through which the movable shaft can horizontally and freely travel. After the auxiliary device is used, the maximum stroke speed of the test machine is increased to 1200 mm/s, and the use range of the test machine is enlarged.
Description
The utility model belongs to heat, mechanical test field, mainly be applicable to the Gleeble testing machine to material carry out that high speed drawn, compressive strain tests.
When the forging of research metal material, shop characteristic such as rolling, usually need higher deformation velocity, and existing in the world at present several heat, mechanical simulation test machine.Mostly can not satisfy this requirement fully.Although Gleeble 1500 heat, mechanical simulation test facility have more superior performance, higher dop movement velocity (100mm/s) can be provided, but the testing requirements of the higher dop movement velocity of can not satisfying the demand, this just draws, presses the research work of test to bring certain difficulty at a high speed to some.
The purpose of this utility model is to provide a cover can satisfy various high speeds and draw, press testing requirements, makes the high energy of dop movement velocity reach heat, the mechanical simulation test machine servicing unit of 1200mm/s.
Based on the foregoing invention purpose, the utility model servicing unit, design and installation is in the periphery of tension and compression moving axis, between fuselage and the moving dop, its characteristics are: it is by tension and compression cover card, the precompressed deck, precompression screw, stage clip, the rotation adjusting pressuring handle is formed, described tension and compression are overlapped to block for socket type and have one along the horizontal axis direction and can be held the cavity that tension and compression moving axis level is freely advanced, its end is by being connected as a single entity on the fastening connector that is stuck in force transducer of screw and with moving dop, and the other end is fastening with screw and precompressed deck, the precompressed deck be shaped as disjunctor three rings, middle ring opening overlaps the left end cavity mouth that blocks with tension and compression and communicates, horizontal axis coincide and its diameter greater than the diameter of moving axis, on the precompressed deck, respectively go here and there down a precompression screw in two end ring, on, overlap compression spring and rotation adjusting pressuring handle in the following screw rod respectively, again last, following precompression screw injects in the hexagon ring of fuselage.
Tension and compression cover cartoon chamber width from left to right is 0～20mm.
When carrying out tension test, the precompressed deck, precompression screw, stage clip, the rotation adjusting pressuring handle can take off maybe will rotate adjusting pressuring handle retreat to the fuselage place all can, purpose be the setting range of stretch in make moving axis not be subjected to the binding force of stage clip.
The utility model design tension and compression cover card and prepressing device, tension and compression cover card chucking is pressed on the moving dop of Gleeble testing machine, the moving dop of moving axis and testing machine is connected as a single entity, and moving axis has the free travel of 0-20mm in the cover card, reason is that any object all has inertia, make dop reach a certain specific speed from stationary state, need regular hour and stroke distances, the high speed of the utility model design is drawn, press servicing unit to make when the high speed tension and compression test of carrying out material, by using the tension and compression cover card of 0-20mm free travel, make dop before the tension and compression sample, zero load reaches predetermined speed.Can adjust stroke distances according to the deformation velocity of testing requirements at the trial, make it in the corresponding time, to reach predetermined movement velocity from stationary state.
Compared with prior art, advantage of the present utility model is:
Gleeble 1500 testing machines have increased after this cover servicing unit, have enlarged its usable range greatly, have improved the performance of equipment.The testing machine stroke speed that Gleeble testing machine maximum stroke speed originally increases less than 100mm/s behind this servicing unit improves greatly, maximum stroke speed can reach 1200mm/s, so just the hot-working character research for material provides convenience, and some high speed that may not carry out draws, presses test to come true before making.
Below in conjunction with accompanying drawing the utility model servicing unit is described further.
Fig. 1 is the structural representation of facing of the utility model servicing unit.
Fig. 2 for the utility model moving axis operation time-length velocity relation figure.
Fig. 3 is the distance-length velocity relation figure of the utility model moving axis operation.
1 is tension and compression cover card, and 2 are the precompressed deck, and 3 is precompression screw, and 4 is stage clip, and 5 are the rotation adjusting pressuring handle, and 6 is fuselage, and 7 are the tension and compression moving axis, and 8 is force transducer, and 9 are moving dop, and 10 is sample, and 11 is quiet long head, and 12 is cavity.
The utility model tension and compression cover card 1 is for socket type and have one along the horizontal axis direction and can hold the cavity 12 that tension and compression moving axis 7 is freely advanced, one end of tension and compression cover card 1 is by being connected as a single entity on the fastening connector that is stuck in force transducer 8 of screw and with moving dop 9, and the other end is fastening with screw and precompressed deck 2, put between moving dop 9 and the quiet dop 11 and draw or press sample, the horizontal free travel that 0-20mm is arranged in the cavity 12 of tension and compression cover card 1, according to test tension and compression rate request, set free travel distance and time corresponding, make dop before the tension and compression sample, reach predetermined speed.Precompressed deck 2 be shaped as disjunctor three rings, middle ring opening communicates with cavity, the moving axis level is freely advanced, respectively go here and there a precompression screw 3 in the precompressed deck 2 upper/lower terminal rings, overlap compression spring 4 and rotation adjusting pressuring handle 5 more respectively, inject then in the hexagon ring of fuselage 6, thereby whole servicing unit is fixed between fuselage 6 and the moving dop 9, can not rotate voluntarily.Before compression test, moving axis 7 can be unloaded, press precompressed deck 2 and tension and compression cover card 1 by adjusting pressuring handle 6 by stage clip 4, promote moving dop 9 by force transducer 8 again, compress cylindrical sample 10, because of moving dop 9 and quiet dop 11 also as the electrically heated conductor before sample 10 compression tests, institute thinks the assurance heating quality, make sample 10 two ends not produce electric arc, available adjusting pressuring handle 5 is transferred to minimum precompression, simultaneously, and when sample 10 heater wires expand, can decompose by stage clip 4, be unlikely that stress crosses that ambassador's sample produces permanent strain and the precision that influences test.
Gleeble heat, mechanical simulation test machine, originally be moving axis 7 and 8 fastening one of pressure transducer, therefore the dop movement velocity is 100mm/s to the maximum, after this servicing unit is used in design, the dop movement velocity is 1200mm/s to the maximum, promptly be original 12 times, brought into play the ultimative function of Gleeble, thoroughly satisfied present testing requirements.
