Each portion comprises a clamping aligning portion (1), a handle (4), a sample clamping portion (2), a thermoelectric couple outlet groove (3) and a sample hole, the radian of the sample clamping portion (2) is same as that of a thermal simulation compression hammering block, and the thermoelectric couple outlet groove (3) is arranged on the clamping aligning portion (1). The thermal simulation sample installation clamping device is simple in structure and novel in design, better solves two problems of uniformity in sample temperature and uniform transformation and breaking of couple wires during heating.
Description
Technical field
The utility model belongs to the thermal modeling test Instrument technology field, and particularly a kind of thermal simulation sample is installed clamping device.
Background technology
Hot modeling test machine can the simulation material hot procedure; Comprise the physical simulation of technological processs such as rolling, forging, welding, casting and research of basic material etc.; Be characterized in adopting the resistance heated mode,, utilize to be welded in the galvanic couple silk on the sample through parameters such as the temperature in computer programming setting and the controlled deformation process, speed, deformation extent, cooling velocities; Gather in real time and the feedback specimen temperature; The control heating power to reach the program setting temperature, can confirm accurately that deformation condition is to deformational behavior and metal structure Effect on Performance; Be the important means of modern material process experimental study, play effect aspect many in the exploitation that improves steel products performance and new varieties, new technology etc.Thermal simulation compression sample commonly used is of a size of Φ 8 * 12mm, and the sample galvanic couple silk of burn-oning should be noted 2 points when sample is installed: the first, the sample center should with two pressure heads (Φ 20mm tungsten carbide hammering block) center-aligned, make sample temperature more even with distortion; Second; Avoid bumping galvanic couple silk (Φ 0.2mm); The galvanic couple silk breaks when preventing to heat, and is used for gathering in real time and the galvanic couple silk of feedback specimen temperature is the center that is welded in the outside surface axis direction of Φ 8 * 12mm with spot welder, is about to being welded on the sample outside surface through instantaneous pressure point of discharge soldering method foremost of two galvanic couple silks; The front end of every galvanic couple silk only has a solder joint, and the distance between two solder joints foremost of two galvanic couple silks is less than 1mm.Hot modeling test machine adopts the electric-resistivity method heated sample, and firing rate is very fast, can reach the thousands of degree of per second, and used galvanic couple silk is very thin, the thermometric lag phenomenon of having avoided thick galvanic couple silk ribbon.When heating, the galvanic couple silk breaks easily, causes the failure of an experiment.
Summary of the invention
The purpose of the utility model is to provide a kind of thermal simulation sample that clamping device is installed.Galvanic couple silk two problems of breaking when having solved sample temperature with all even heating of distortion.
The utility model comprises left-right symmetric two parts, and each part comprises clamping aligned portions, handle, sample holder part, thermopair lead-out groove, sample well.
Sample holder part is identical with thermal simulation compression hammering block radian, opens the thermopair lead-out groove on the clamping aligned portions, can realize: the first, the sample center should with two pressure heads (Φ 20mm tungsten carbide hammering block) center-aligned, can make sample temperature more even with distortion; The second, avoid bumping galvanic couple silk (Φ 0.2mm), the galvanic couple silk breaks when preventing to heat.
The clamping aligned portions is of a size of Φ 20 * 10mm; The sample holder portion size is Φ 8 * 10mm, and is consistent with the compression sample outside dimension; It is wide that the thermopair lead-out groove is of a size of 3mm; Grip size is Φ 15 * 350mm.
The advantage of the utility model is: this apparatus structure is simple, modern design, galvanic couple silk two problems of breaking when having solved sample temperature with all even heating of distortion well.

Embodiment
Fig. 1-2 is the specific embodiment of the utility model
The utility model comprises left-right symmetric two parts, and each part comprises clamping aligned portions 1, handle 4, sample holder part 2, thermopair lead-out groove 3, sample well.
Sample holder part 2 and thermal simulation compression hammering block radian is identical, opens thermopair lead-out groove 3: the first on the clamping aligned portions 1, the sample center should with two pressure heads (Φ 20mm tungsten carbide hammering block) center-aligned, can make sample temperature more even with distortion; The second, avoid bumping galvanic couple silk (Φ 0.2mm), the galvanic couple silk breaks when preventing to heat.
Clamping aligned portions 1 is of a size of Φ 20 * 10mm; Sample holder part 2 is of a size of Φ 8 * 10mm, and is consistent with the compression sample outside dimension; It is wide that thermopair lead-out groove 3 is of a size of 3mm; Handle 4 is of a size of Φ 15 * 350mm.During the dress sample; Compression sample is of a size of Φ 8 * 12mm; The sample holder part 2 of packing into; Be used for gathering in real time and the galvanic couple silk (Φ 0.2mm) of feedback specimen temperature is the center that is welded in the outside surface axis direction of Φ 8 * 12mm with spot welder, the galvanic couple silk is drawn by thermopair lead-out groove 3, can avoid bumping unintentionally the galvanic couple silk.After installing like this, two parts are lumped together, clamp sample; Then, it is packed between the anchor clamps of the hot modeling test machine left and right sides, in order sample just in time to be contained in the middle of the anchor clamps of the left and right sides; The thermal simulation sample is installed clamping aligned portions 1 on the clamping device, and (Φ 20 * 10mm) cylindricals align with left and right sides anchor clamps hammering block (Φ 20mm) cylindrical, behind the clamping sample, unload the thermal simulation sample clamping device is installed; Like this, sample center and two hammering block centers point-blank, thereby guarantee that temperature is more even with distortion.
