Testing

Workshop

Contents and methods of first inspection, intermediate sampling inspection, and caster inspection

1, intensity

1) Strength testing or sampling inspection should be carried out in accordance with design drawings and processing requirements. The hardness tester shall be reviewed with the standard block, and the test intensity can be carried out after confirmation. The heat-treated parts are tested with Rockwell hardness tester.

2) Before testing the strength, the surface of the parts should be cleaned and tidy, oxide scale, carburized layer and burrs should be removed, and there should be no prominent machining marks on the surface. The temperature of the tested parts is based on the indoor temperature, or slightly higher than the indoor temperature. The temperature is limited to everyone must be able to properly grasp it.

3) The strength inspection components should be clarified according to the process documents or by the inspection and processing personnel. The inspection strength of the heat treatment position is not less than 1 point, and each point is not less than 3 points. The unevenness of the general strength value should be less than or equal to HRC5 degrees.

2, deformation

1) Metal sheet parts are placed on the testing service platform with a micrometer to detect their unevenness.

 2) For shaft parts, use pointed or V-shaped blocks to support both sides of the point. Use an inner diameter dial indicator to measure the axial vibration. Fine shaft parts can be checked on the website with a micrometer.

3) For round parts, use inner diameter dial gauges, micrometers, thread plug gauges, inner diameter dial gauges, thread plug gauges, ring gauges, etc. to inspect the internal hole, internal thread, external thread and other specifications of the parts.

4) Special testing tools for non-standard external threads to be tested and unique parts.

3. Appearance: Use your eyes to observe whether there are cracks, burns, knocks, black spots, rust, etc. on the surface. For key parts or parts that are prone to cracks, use gasoline blasting and other methods to check.

4. Features: testing by testing equipment.
