The use of rivets varies according to the type of rivets and specific application scenarios, but the following are some general use steps and precautions:
First, preparation
1. Select the right rivets: Select the right rivets according to the material, thickness and working environment of the connected object. Common types of rivets include copper rivets, aluminum rivets, stainless steel rivets, etc.
2. Prepare tools: Prepare the corresponding riveting tools according to the type of rivets, such as riveting gun, hammer, pliers, etc. Make sure the tools are in good working order.
3. Clean the connection surface: ensure that the surface of the object to be connected is clean, smooth, and free of oil or other stains to ensure the quality of the riveting.
Second, riveting step
1. Pre-punch holes: Punch holes in the object to be connected to ensure that the aperture matches the diameter of the rivet. For some rivets, such as pulling rivets, it may be necessary to use a round hole punch to punch holes from the front before installation.
2. Install rivet: 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. For rivets using rivet guns, such as core-pulling rivets, the rivet assembly needs to be inserted into the through hole of the fitting.
3. Tighten the rivets:
For rivets that use a hammer, such as copper rivets, hammer the tail of the rivet into the surface of the object until the tail of the rivet is slightly bent and tightly fitted to the surface of the object.
For rivets using rivet guns, such as core-pulling rivets, use the rivet gun to pull off or press the end of the rivet to complete the riveting. In the operation process, it should be ensured that the axis of the rivet gun is consistent with the axis of the rivet hole to avoid skew.
4. Check the connection: Use pliers or other tools to gently tap the connection to ensure that the rivets are firmly connected and not loose. Check whether the surface of the connected object is damaged to ensure the quality of the riveting.
Third, precautions
1. Select the right rivets: Ensure that the diameter, length and material of the rivets meet the requirements of the connected object. Avoid using too small or too large rivets, so as not to affect the riveting quality.
2. Control strength: During the riveting process, avoid excessive force to avoid damaging the surface of the object or the rivet itself. For rivets using rivet guns, it should be ensured that the air pressure or hydraulic pressure is moderate to avoid poor pulling effect or sticking.
3. Safe operation: When operating the riveting tool, ensure that the safe operation procedures are followed, and wear protective glasses and gloves to avoid accidental injury. When using pneumatic riveting gun, the air source must be disconnected when assembling and disassembling parts.
4. 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.
5. 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.
Through the above steps and precautions, you can ensure the correct use of rivets and obtain good riveting effect. In actual operation, the appropriate rivets and tools should be selected according to the specific situation, and the corresponding operating procedures and safety requirements should be followed.
