The utility model is mainly composed of a test specimen chamber, top and bottom press heads, a pipe-shaped seat and a claw-shaped seat. The outstanding feature of the high temp. Press fast cooling tester is that the compressing and cooling actions are completed on a device. The utility model has the advantages of simple structure, flexible action, high reliability, convenient operation, high speed, safety and uniformity, no additionally mechanical deformation, etc.
Description
The utility model relates to a kind of high temperature compressed quick cooling test device of metal at the dynamic microstructure change procedure of high temperature deformation that be used for studying.
In recent years about the theory of dynamic recrystallization with experiment showed, metal material in the process of high temperature deformation, if dynamic recrystallization has taken place, so this distortion stop moment, so-called inferior dynamic recrystallization will take place hastily, and does not need incubation period.The existence of this dynamic recrystallization has brought sizable difficulty for the observation of dynamic recrystallization microstructure and the research of plasticity and superplastic deformation mechanism aspect.Therefore, stop moment in high temperature deformation, sample is implemented cooling fast, keeping the high temperature deformation tissue and being needs a problem solving on the experimental technique.
The quick cooling test device of existing high temperature deformation is that the water spray of the high temperature test specimen in the induction coil is implemented cooling fast, to obtain to keep the high temperature deformation tissue, the shortcoming of this device is a complex structure, inconvenient operation, the test specimen cooling is long at interval retardation time, and inhomogeneous.In addition, constant in also can breaking plant, the even temperature environment.
The purpose of this utility model is to overcome the above-mentioned shortcoming that existing device exists, and high temperature compressed function and quick cooling function are combined in one, and design has simple in structure, and flexible movements are reliable, and easy to operate, safety is made economic utility unit.
Above-mentioned purpose realizes by following measure: on promptly having, the high temperature compressed quick cooling test device of push-down head, on in its closed furnace body (2), push-down head (3), sample chamber (4) is housed (7), be loaded in the sample chamber (4) for the movable sample (5) that connects between it, and connect by the activity of push-down head movable block (6) and push-down head (7), seaming chuck (7) bottom is provided with tubular seat (10), and by claw type seat (9) connection, which is provided with operating rod (13), the last correspondence of tubular seat (10) has and can make the claw type groove that slips into its inner chamber when claw type seat (9) rotation appropriate location, tubular seat (10) inner chamber is provided with snubber assembly (11), the upper surface of tubular seat (10) is provided with the disengaging plate (8) that sample chamber (4) and sample (5) are ejected, and tubular seat side is provided with cooling pond.
Pawl on the claw type seat (9) in this device is answered 〉=3.
The principle of work of this device is: be compressed sample (5) and push-down head loose piece (6) and pack in the sample (4), and it is contained between upper and lower pressure head (3), (7), because sample chamber (4) and upper and lower pressure head (3), (7) all in the heating furnace body (12) of sealing, therefore are heated.When the testing machine moved cross beam moves downward, sample (5) is compressed by seaming chuck (3).When sample is compressed to sometime (corresponding dependent variable), in the time of need cooling off sampling fast, just can handle the handle (13) that is located on the claw type seat (9), make claw type seat (9) be rotated in certain angle, pawl on the pawl type seat is overlapped with the corresponding groove of tubular seat (10), so, push-down head (7) just disengages immediately with tubular seat (10), under the effect of gravity, glide rapidly, fall into tubular seat (10) inner chamber, meanwhile, push-down head loose piece (6) and sample rifle (4) are taken sample (5) and are also fallen thereupon.When dropping down onto the height of disengaging plate (8), just broken away from leaf spring and dropped down onto in the outer cooling pond of stove, thereby reached the cold purpose of speed.
This programme is compared with existing device and is had the following advantages:
1. can be in different dependent variables, under strain rate and the deformation temperature, realization is cooling fast, cools off to be spaced apart △ t＜2sec retardation time; 2. this device does not influence normal compression deformation, does not destroy constant uniform temperature environment in the thermostat; 3. this device does not require electronics compression test and the thermostat that changes existing weaponry and equipment, and simple in structure, and flexible movements are reliable, and easy to operate, safety is made economy, is convenient to use.
Description of drawings:
Fig. 1 is the quick cooling test device of a drawing by high temperature front view;
Fig. 2 is the A-A cut-open view of Fig. 1;
