Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thermal simulation test instruments, in particular to a clamp for transferring cylindrical thermal simulation samples. Background Art
[0002] For materials and thermal processing, physical simulation usually uses small-sized specimens and dynamic thermal simulation devices to reproduce the physical process of materials being heated and stressed during preparation or thermal processing. Rheological stress measurement, dynamic CCT, static CCT and ordinary thermal cycle process simulation often use small cylindrical specimens. The specimen size is generally φ8*12mm or φ10*15mm. The size of the clamping specimen anvil of the thermal simulation experimental device is φ20mm.
[0003] At present, most of the samples are clamped and transferred using tweezers or pliers, which may cause unstable clamping of the sample during the transfer process. If the sample lacks positioning guidance and is difficult to align and clamp in the center area of the anvil end face, the sample will be unevenly controlled in the heating process and unevenly deformed in the compression process.

DETAILED DESCRIPTION
[0023] This embodiment discloses a fixture for transferring cylindrical thermal simulation specimens. Figure 5 , including a sample clamping port 100, an elastic rope 200 and a positioning block 300.
[0024] Please refer to Figure 1 and Figure 2 The sample clamping port 100 includes a bottom plate 110, a first side plate 120 and a second side plate 130. The bottom plate 110 has a first end and a second end opposite to each other. One end of the first side plate 120 is connected to the bottom plate 110 at the first end, and one end of the second side plate 130 is connected to the bottom plate 110 at the second end. The other end of the first side plate 120 and the other end of the second side plate 130 are close to each other to form a close opening 140. The first side plate 120 and the second side plate 130 are limited to be elastic. When the clamp is used, the cylindrical thermal simulation sample 20 can be squeezed in from the close opening 140. In this process, the first side plate 120 and the second side plate 130 are deformed and can be restored to their original state.
[0025] Please refer to Figure 1 and Figure 2, the two ends of the elastic rope 200 are respectively fixed to the first side plate 120 and the second side plate 130, and the elastic rope 200 is arranged between the first side plate 120 and the second side plate 130. When the cylindrical thermal simulation specimen 20 is squeezed in from the approaching opening 140, the elastic rope 200 will be deformed under the pressure of the specimen, and the elastic rope 200 will press the cylindrical thermal simulation specimen 20 and push the specimen against the inner side of the first side plate 120 and the second side plate 130. In this embodiment, the facing side of the first side plate 120 and the second side plate 130 is the inner side, and the away side is the outer side.
[0026] Please refer to Figure 5 , the positioning block 300 is fixedly connected to the bottom plate 110. Figure 3 , Figure 4 and Figure 5 A minor arc surface 310 is provided on one side of the positioning block 300 facing the sample clamping port 100, and the diameter of the minor arc surface 310 is limited to be equal to the diameter of the anvil on which the cylindrical thermal simulation specimen 20 is to be placed. Wherein, under the condition that the cylindrical thermal simulation specimen 20 is fixed between the first side plate 120, the second side plate 130 and the elastic rope 200, the axis of the cylindrical thermal simulation specimen 20 coincides with the axis of the minor arc surface 310.
[0027] The minor arc surface 310 is composed of countless arcs, and the arcs correspond to the centers of circles. Countless centers of circles are connected to form a line segment, and the straight line where the line segment is located is the axis of the minor arc surface 310.
[0028] The use process of the clamp is as follows: first, the cylindrical thermal simulation sample 20 is squeezed into the interior of the clamping port 100 from the closing port 140 of the clamping port 100, so that the elastic rope 200 abuts against the cylindrical thermal simulation sample 20, and the cylindrical thermal simulation sample 20 abuts against the inner sides of the first side plate 120 and the second side plate 130, forming an effect that the clamping port 100 "bites" the sample. At this time, the spatial position of the cylindrical thermal simulation sample 20 in the clamping port 100 is determined; then, Transfer the fixture as a whole, transfer the sample to the middle of the anvil chuck of the dynamic thermal simulation device, and fit the inferior arc surface 310 of the positioning block 300 tightly with the side of the anvil. At this time, the end face center of the cylindrical thermal simulation sample 20 and the end face center of the anvil basically coincide, and the sample is aligned with the center area of the anvil; rotate the displacement knob of the dynamic thermal simulation device to make the anvil firmly clamp the cylindrical sample; after the anvil firmly clamps the cylindrical thermal simulation sample 20, pull out the fixture to complete the sample transfer and loading process, and conduct subsequent tests.
[0029] The clamp can stably clamp the cylindrical thermal simulation sample 20, effectively preventing the cylindrical sample from falling during the clamping and transfer process, and ensure that the sample is clamped in the center area of the anvil after loading, ensure that the sample is evenly heated during the heating process, ensure that the sample is evenly deformed during the compression process, and extend the service life of the anvil.
[0030] When using tweezers or pliers to transfer the sample, especially when using two cylindrical samples to simulate the rolling of composite plates, the thermocouples welded to the side surface of the sample may overlap or even fall off due to the force. To solve this problem, please refer to Figure 2 In some embodiments, the first side plate 120 and the second side plate 130 are both provided with a notch 170 , and the thermocouple of the cylindrical thermal simulation specimen 20 extends out from the notch 170 , which can prevent the positive and negative thermocouples from overlapping or being squeezed and falling off.
[0031] In some embodiments, see Figure 1 and Figure 2 The first side plate 120 is connected to the first outer flap 150 at one end away from the bottom plate 110, and the second side plate 130 is connected to the second outer flap 160 at one end away from the bottom plate 110. The first outer flap 150 and the second outer flap 160 are away from each other, which plays a guiding role in the process of squeezing the cylindrical thermal simulation specimen 20 from the approaching mouth 140, making it easier for the specimen to be bitten into.
[0032] In some embodiments, see Figure 1 and Figure 2 The first side plate 120 and the first outer flap 150 have a smooth transition, and the second side plate 130 and the second outer flap 160 have a smooth transition, which further facilitates the biting process of the sample.
[0033] In the scheme where the first outer flap 150 and the second outer flap 160 are provided, the notch 170 may also extend to the first outer flap 150 and the second outer flap 160. Figure 1 and Figure 2 The first side plate 120 and the first outer flap 150 jointly define a notch 170 , and the notch 170 cuts off the first outer flap 150 ; the second side plate 130 and the second outer flap 160 jointly define a notch 170 , and the notch 170 cuts off the second outer flap 160 .
[0034] The elastic rope 200 may be in the form of a rubber band.
[0035] In some embodiments, by setting a hook, the elastic rope 200 is hung on the barb 180, which facilitates the installation and replacement of the elastic rope 200. Specifically, a barb 180 is fixedly installed on the side of the first side panel 120 facing away from the second side panel 130, and a barb 180 is fixedly installed on the side of the second side panel 130 facing away from the first side panel 120.
[0036] In some embodiments, the bottom plate 110 of the sample clamping port 100 is connected to the positioning block 300 by screws, and a threaded hole 321 is provided in the positioning block 300. Figure 3 and Figure 4As shown, the threaded hole 321 is used for screw connection.
[0037] In some embodiments, see Figure 4 The positioning block 300 is provided with a mounting plane 320 connected to the positioning block 300 , the positioning block 300 makes large-area contact with the bottom plate 110 of the sample clamping port 100 , and inferior arc surfaces 310 are provided on opposite sides of the mounting plane 320 .
[0038] In some embodiments, the positioning block 300 is made of aluminum, which has the advantage of being lighter in weight.
[0039] In some embodiments, the center angle of the minor arc surface 310 is controlled within a range of 90° to 150°, and preferably, the center angle of the arc of the minor arc surface 310 is 120°.
