Blind rivets are prone to problems and solutions when they are used

There are some common problems that blind rivets may encounter during use, and here are some of them and possible solutions:

Rivets do not fit properly or are pressed in completely:

Cause: It may be due to incorrect rivet selection, or the hole size of the workpiece does not match the rivet.

Solution: Make sure that the rivet you choose matches the hole size of the workpiece and that you choose the right length of rivet. Also, check that the riveting tool (e.g. riveting machine) is adjusted correctly and make sure that the crimping joint matches the rivet.

Rivets bent or broken:

Cause: This can be due to the rivet being too long or too short, causing excessive stress to be crimped, causing the rivet to bend or break.

Solution: Make sure to choose the right length of rivets and avoid rivets that are too long or too short. At the same time, check the pressure regulation of the riveting tool to ensure that the pressure applied during crimping is moderate and not excessive.

Rivets are not fully locked or are loose:

Cause: It may be caused by an uneven surface of the workpiece or poor contact between the crimping joint and the workpiece.

Solution: Before crimping, make sure that the surface of the workpiece is flat and clean, and that the crimping joint is in good contact with the workpiece. If it is caused by the uneven surface of the workpiece, you can consider adjusting the processing method of the workpiece or using other fixing methods.

Bubbles or dents after crimping:

Cause: This may be due to a void in the bottom of the workpiece or an uneven surface of the workpiece during crimping.

Solution: Before crimping, make sure that the surface of the workpiece is flat and clean, and that it is in sufficient contact with the support surface underneath to prevent bubbles or dents.

Nail or core jamming occurs during crimping:

Cause: This may be due to improper selection of rivets or improper use of crimping tools.

Solution: Make sure that the rivets selected match the hole size of the workpiece and that the crimping is done with the appropriate crimping tool. When crimping, it is necessary to ensure that the crimping action is stable and continuous, and avoid the phenomenon of stuck nails or stuck cores.

By carefully investigating the causes of the problem and taking appropriate solutions, the problems that may be encountered in the use of blind rivets can be effectively solved and the quality and reliability of the crimping effect can be ensured.
