Handle the hacksaw frame test report QB T 1108
As a common tool, hacksaw stands have a wide range of applications in many fields. However, it is very important to control its performance and quality, so it has become a necessary step to handle the hacksaw frame inspection report. The QB T 1108 standard is an important standard for the performance testing of hacksaw frames, and this article will focus on the testing requirements and processes of the tensile performance, parallelism, basic size, surface quality, handle and tensioning device of hacksaw frames.
1. Quality inspection of tensile performance.
Tension performance is one of the important properties of the hacksaw frame, which determines the stability and reliability of the hacksaw during use. According to the QB T 1108 standard, the tensile properties of the hacksaw frame need to be tested. The specific steps are as follows:
1.Place the hacksaw frame on a special inspection device and adjust it to a standard position.
2.Load a certain weight of hacksaw on the hacksaw frame to make sure that the hacksaw fits snugly with the hacksaw stand.
3.Detect the deformation of the hacksaw frame under a certain pressure, as well as the stability of the hacksaw.
4.The test data is recorded to evaluate whether the tensile performance of the hacksaw frame meets the requirements of the standard.
2. Parallelism detection.
Parallelism is an important indicator to evaluate the manufacturing quality of the hacksaw frame, which can directly affect the use of the hacksaw. When performing a parallelism test, the following steps need to be followed:
1.Choose the right measuring tool like micrometer, gauge, etc.
2.Measure the various parts of the hacksaw frame and record the data.
3.Analyze the measurement data to determine whether the parallelism of the hacksaw frame meets the requirements of the standard.
4.If it does not meet the requirements of the standard, the hacksaw stand needs to be adjusted or repaired.
3. Basic size testing.
The basic size is an important index to evaluate whether the hacksaw frame meets the design requirements. When performing a basic dimensional inspection, the following steps need to be followed:
1.According to the QB T 1108 standard, check whether the basic dimensions of the hacksaw stand meet the requirements.
2.Use the measuring tool to measure the various parts of the hacksaw frame.
