Multi-angle drop-hammer impact testing device and test bench thereof

Abstract

The invention discloses a multi-angle drop-hammer impact testing device. The multi-angle drop-hammer impact testing device comprises a test bench for fixing a test specimen, a drop-hammer assembly and a lifting mechanism, wherein the drop-hammer assembly is correspondingly arranged above the test bench by the lifting mechanism; the test bench comprises a test bench main body and an angle adjustment mechanism for adjusting the rotation of the test bench main body, and the drop-hammer assembly is kept to correspond to the test specimen on the test bench main body by a hammer adjustment mechanism. The invention also discloses the test bench of the multi-angle drop-hammer impact testing device using the structure. The test bench main body rotates by a preset angle by the angle adjustment mechanism, so as to simulate the impacts from different angles; the drop-hammer assembly is allowed to impact the test specimen from different angles, and the impacts comprise front-surface impact, the offset impact and the lateral impact, so that the material mechanical properties of the test specimen can be analyzed from different impact angles, and the flexibility and universality of the drop-hammer impact test are greatly improved.

Description

technical field [0001] The invention relates to a drop weight impact device, in particular to a test bench for the drop weight impact device. Background technique [0002] At present, in the quality management process of many products, it is also indispensable to measure the impact resistance of the product. In the existing general drop weight impact test, the drop weight in the drop weight impact device is dropped vertically, and the specimen clamped on the test bench of the drop weight impact device is directly impacted, so as to study the performance of the specimen material under the frontal impact. Impact resistance, flexural strength, tensile strength, etc. [0003] After the specimen is clamped by this kind of drop hammer impact device, most of them can only achieve frontal impact test, and it is difficult to realize multi-angle drop weight impact test on a single drop weight impact device, such as offset impact, side impact, etc. Even if the multi-angle drop weight...

AI Technical Summary

Problems solved by technology

[0003] After the specimen is clamped by this kind of drop hammer impact device, most of them can only achieve frontal impact test, and it is difficult to realize multi-angle drop weight impact test on a single drop weight impact device, such as offset impact, side impact, etc.

Even if the multi-angle drop weight impact test is realized, the operation is very cumbersome, and the flexibility and extensiveness of the impact test need to be improved

[0004] In addition, the current impact test is a one-time test, and the test process is completed at one time. However, due to some specific circumstances, it may be necessary to terminate the test midway and prevent the drop weight from impacting the test piece or the test bench, so that the test piece can still Repeated use, the test piece is reusable and can save costs. Therefore, it is of great practical significance to develop a termination device during the impact test
