Description

Technical Field

[0001] The invention relates to the technical field of material performance testing devices, and in particular to a metal material continuous multiple flushing and ablation device. Background Art

[0002] High-strength and toughness steel has the characteristics of high wear resistance, high toughness, high strength, excellent fatigue resistance and processing performance. It is widely used in national defense, bridges, construction, ships, vehicles, special equipment and other fields; at the same time, high-strength and toughness steel plays an irreplaceable role in multiple industrial fields and high-end manufacturing, and has become one of the most widely used metal materials.

[0003] When using high-strength and toughness steel to make gun barrels, their parts will be subjected to continuous and multiple instantaneous scouring and ablation of high-temperature, high-speed gunpowder gas during use, which may cause melting, structural changes, thermal cracks in the inner bore matrix of the barrel, as well as high-temperature burning of the barrel and peeling of the inner wall coating. Therefore, in the design and manufacturing process of gun barrels using high-strength and toughness steel, it is usually necessary to subject the molded samples to high-temperature, high-pressure, high-speed gas scouring and ablation to verify the reliability and stability of the molded samples. However, the existing semi-closed explosive devices can only carry out a single erosion and ablation test, that is, after a erosion and ablation test, it is necessary to re-install and re-position the process steps, and it is impossible to achieve multiple continuous high-temperature, high-pressure, and high-speed gas erosion and ablation tests in a short interval time, and thus it is impossible to effectively simulate the actual use conditions of the gun barrel (re-installation and re-positioning process is easy to cause the relative position between the test sample and the test device to change, and secondly, it is impossible to test under the same environmental system, thereby increasing the error, randomness and uncontrollability of the test). As a result, there is a lack of damage data on the gun barrel in a single round of continuous high-temperature, high-pressure, and high-speed gas erosion and ablation, and it is impossible to truly and effectively evaluate the relevant performance of the gun barrel made of high-strength and toughness steel in actual application. Summary of the invention

The end of the spline shaft 541 away from the screw 51 is connected to the spring groove 12 via a return spring 543 (combined with Figure 2 and Fig. 9 As shown), the inner wall of the spring slot 12 has a keyway corresponding to the spline of the spline shaft 541 (at the same time, in the initial position, the outer wall of the end of the spline shaft 541 away from the screw rod 51 is rotationally connected to the inner wall of the spring slot 12).

[0033] The central axes of the support ring 23, the fixed ring 33 and the rotating ring 43 are collinear, and the inner diameters of the support ring 23, the fixed ring 33 and the rotating ring 43 are consistent; the erosion and ablation generator 30 is installed on the clamping fixture (that is, the erosion and ablation generator 30 passes through the first through hole 331 and is clamped and positioned by the three-petal inclusive clamping mechanism on both sides of the first through hole 331), and the test sample 40 is installed on the positioning fixture (the test sample 40 passes through the second through hole 431, is supported by the positioning mechanism, and is clamped and fixed by the clamping mechanism), and the positioning fixture corresponds to the clamping fixture (that is, it is ensured that the test sample 40 on the positioning fixture corresponds to the erosion and ablation generator 30 on one of the clamping fixtures).

[0034] Working principle: The steps of the scouring and ablation device for performing multiple continuous scouring and ablation of metal materials are as follows: First, according to the test requirements, the number of erosion and ablation generators 30 and the number of test samples 40 are selected to select the support assembly, the fixing assembly and the positioning assembly (in this embodiment, 8 support seats 24 of the support assembly are selected, 8 first through holes 331 on the fixing assembly are provided, and 1 second through hole 431 on the positioning assembly is provided); and the erosion and ablation generators 30 are placed in the corresponding first through holes 331, and the test samples 40 are placed in the corresponding second through holes 431, and the test samples 40 are fixed and positioned by the positioning fixture (specifically: the test samples 40 are placed by Figure 1 The test sample 40 is inserted into the second through hole 431 from the left side to the right side as shown until the right end of the test sample 40 is supported by the positioning baffle 443 of the positioning mechanism. At this time, the arc-shaped sliding block 342 and the sliding rod 344 of the clamping mechanism move toward the direction close to the fixed sleeve 441 due to the supporting force of the test sample 40, and the compression spring 345 is in a compressed state, thereby realizing the elastic clamping of the test sample 40 by the clamping mechanism).

[0035] Then, the screw 51 is started to rotate, and the screw 51 drives the second slide seat 41 to move toward the side close to the fixed seat 31 through the sliding block 52. At this time, since the steering spline 5420 is engaged with the spline groove and the spline shaft 541, Figure 2 The left end shown is rotationally connected to the spring groove 12, so the rotation of the screw rod 51 simultaneously drives the spline shaft 541 to rotate, and the spline shaft 541 drives the gear ring 35 to rotate through the driven gear 353 and the intermediate gear 352. During the rotation of the gear ring 35, the arc-shaped slide groove 351 drives each connecting rod 340 to move in the vertical slide groove 332 toward one end close to the central axis of the fixed ring 33, thereby pulling the sliding sleeve 343 to move, and the sliding sleeve 343 drives the sliding rod 344 and the arc-shaped sliding block 342 to move, thereby achieving the clamping of the scouring and ablation generator 30. After clamping, the sliding block 342 slides in the sliding sleeve 343 and compresses the compression spring 345, thereby increasing the clamping force on the scouring and ablation generator 30.

[0036] After that, the screw 51 is stopped from rotating, and the first slide 21 is pushed (it can be pushed manually or driven by an electric mechanism, and the electric mechanism can be set according to the actual situation). The first slide 21 drives the support ring 23 and the support seat 24 thereon to move toward the side close to the fixed ring 33 through the first bracket 22 until the support seat 24 and the erosion ablation generator 30 are aligned. Figure 1 As shown, the left ends are abutted against each other (ie, the support seat 24 supports the scouring and ablation generator 30 ), and the first slide seat 21 is fixed to the base 10 by fasteners such as screws and bolts.

[0037] Continue to start the screw 51 to rotate. As the screw 51 continues to rotate, the top ring 53 approaches the limit ring 5410, and presses against the limit ring 5410 to follow the sliding block 52 to move toward the side close to the fixed seat 31, so that the steering spline 5420 disengages from the spline groove, and the spline of the spline shaft 541 is engaged in the corresponding key groove of the spring groove 12. At this time, the spline shaft 541 does not rotate due to the limitation of the spring groove 12, and the reset spring 543 is gradually compressed. At the same time, the spline shaft 541 is used to hard limit the rotation of the driven gear 353, and then the intermediate gear 352 is used to hard limit the rotation of the gear ring 35, to ensure that the arc-shaped sliding block 342 is firmly clamped on the erosion generator 30.

[0038] When the test sample 40 corresponds to and contacts one of the erosion and ablation generators 30 (if the test sample 40 does not correspond to any erosion and ablation generator 30 during the movement, the motor 451 drives the rotating ring 43 to rotate to ensure that the test sample 40 corresponds to the erosion and ablation generator 30), the screw 51 is stopped and the corresponding erosion and ablation generator 30 is started to implement the erosion and ablation test of the test sample 40; then, the erosion and ablation generator 30 is stopped and the screw 51 is reversed so that the second slide 41 retreats a distance (i.e., to the left). Figure 1 or Figure 2 The test sample 40 is moved to the right by a distance in the direction shown, and the spline of the spline shaft 541 must be ensured not to be separated from the keyway portion of the spring slot 12), and then the rotating ring 43 is started to rotate a certain angle to correspond to another erosion and ablation generator 30, and the second slide 41 is driven forward by the starting screw 51 to make the test sample 40 contact with the erosion and ablation generator 30, and the erosion and ablation generator 30 is started for testing; this cycle is repeated until the tests of all erosion and ablation generators 30 are completed.

[0039] Finally, the erosion and ablation generator 30 and the test sample 40 are removed for subsequent test result analysis.

The cooling of the corresponding erosion and ablation generator 30 and the fixing seat 31 is realized by introducing cooling liquid or compressed air into the circulating cooling channel.
