When using rivets, in order to ensure riveting quality and operation safety, the following points need to be paid attention to:
First, rivet selection and preparation
1. Select the right rivets: Select the right rivets material, diameter and length according to the material, thickness and working environment of the connected object. For example, steel rivets are suitable for high-strength connections, aluminum rivets are suitable for light weight and corrosion resistance needs, and stainless steel rivets are suitable for corrosive environments.
2. Check the quality of rivets: Check whether the rivets have defects such as cracks, deformation or rust before use to ensure that the rivets are of good quality.
3. Pre-drilling: If necessary, make a good hole in the connected object in advance to ensure that the aperture matches the diameter of the rivet. It is generally recommended that the aperture is slightly larger than the diameter of the rivet by about 0.10mm.
Second, riveting tools and operations
1. Use the right tools: Select the right riveting tools according to the type of rivets, such as pneumatic riveting gun, manual riveting gun, etc. Ensure that the tools are in good working condition, such as the air pressure of the pneumatic riveter should be controlled below 0.7MPa.
2. Safe operation: When operating the riveting tool, ensure that the safe operation procedures are followed, such as wearing protective glasses and gloves to avoid accidental injury. When using pneumatic riveting gun, the air source must be disconnected when assembling and disassembling parts.
3. Correct riveting: Insert the rivet into the hole and ensure that the head of the rivet is flush with the surface of the object or slightly protruding. Use the riveting tool to rivet the rivet tightly, pay attention to keep the axis of the rivet gun consistent with the axis of the rivet hole to avoid skew. During the riveting process, the rivet gun should be pressed slightly to make the rivet tail close to the workpiece surface.
Third, riveting quality inspection
1. Check the riveting firmness: After the riveting is completed, check whether the rivets are firmly fixed on the connected object, without loosening or falling off.
2. Check the surface quality: ensure that the surface of the riveted part is not scratched during the riveting process, and keep the appearance of the workpiece clean.
3. Functional testing: Where possible, functional testing of the riveted part is carried out to ensure that it can withstand the expected load and working conditions.
Fourth, other precautions
1. Avoid overload use: do not use rivets beyond their carrying capacity, so as not to cause rivet breakage or connection failure.
2. Storage and maintenance: Unused rivets should be stored in a dry and ventilated place to avoid moisture and corrosion. At the same time, the riveting tool is regularly maintained and maintained to ensure that it is in good working condition.
To sum up, when using rivets, it is necessary to pay attention to selecting the appropriate rivets and tools, correctly operating the riveting tools, checking the riveting quality and following other precautions. These measures will help improve riveting quality and operation safety.
