Existing drop hammer impact testing machines bounce back after the first impact and subject the pipe to a second impact, which reduces the accuracy of the test results.
The drop hammer assembly is raised to a certain height by a support frame assembly and then falls freely to impact the pipe body. The locking assembly locks the drop hammer assembly during the rebound to prevent secondary impact.
This improved the accuracy of the test results, prevented secondary impacts of the drop hammer on the pipe body, and ensured the reliability of the test data.
