What is the tolerance range of precision screws?
With the continuous improvement of automation technology, human participation in the production process is gradually decreasing, especially in the processing of some small parts, the manual processing efficiency and accuracy are low. Whether the screws can be stably picked up and installed automatically is of great help to improve automated production.
At present, it has become very common to use automated tools to hit screws. However, when the material of the fastening object is relatively soft, the screw fastening is often prone to skew, not sticking, and the screw hole is damaged during the fastening process. Metal shavings can also be created in the shards, which can short out the board.
Traditional rivets have a single purpose and need to be used in combination in most occasions. The operation is complicated, labor-intensive, and the connection quality cannot be guaranteed. Therefore, there is a need for an integrated rivet.
The nuts of some products must be installed on the outside, but due to the small internal space, when the indenter of the riveting machine cannot meet the strength requirements by methods such as riveting and budding, riveting and riveting are impossible. Rivets to be nailed. Applicable to the fixed field of each thickness plate and tube (0.5MM-6MM). Using pneumatic or manual riveting equipment, rivet once and it is easy to secure. Replacement of the existing welding nut to supplement the metal plate, the thin tube welding is easy to melt, and the welding nut is not smooth.
