How are the rivets connected? Count common rivet connections
The type of rivet connection can be classified in many ways. According to the classification, it can be divided into three types: ordinary riveting, sealing riveting and special riveting. According to the riveting and rivet and hole matching properties, it can be divided into interference fit riveting and non-interference fit riveting, shore riveting. The classification of positive workpieces can be divided into double-sided riveting and single-sided riveting. Blind rivets are generally one-sided riveted situations.

First, by purpose
1. Common riveting
In the parts with no special requirements, semi-circular rivets, flat-cone rivets, countersunk rivets, 120° countersunk rivets, and large flat head rivets are used to form standard girders or rivet joints of 900 and 120° sinking heads. .
Ordinary riveting includes: rivet riveting of the rivet, riveting of the countersunk head rivet, also known as countersunk head riveting, double-sided countersunk head riveting.
2. Seal riveting
In the parts where the structure is required to prevent leakage, oil leakage, water leakage and corrosion, different sealing methods are adopted to prevent the rivet connection form of gas or liquid leaking from the inside of the riveting part.
The sealing riveting includes riveting with an additional sealant at the surface of the rivet joint, riveting and interference fit riveting with a sealant or sealing element at the rivet.
3. Special riveting
In the structure where the structure is mainly stressed or not open or closed, a rivet connection form of a ring groove rivet, a high shear rivet, a threaded hollow rivet, a blind rivet or the like different from the ordinary rivet shape and the riveting method is used.
The name of the riveted form is usually named after the name of the rivet, such as ring groove rivet riveting, wire drawing rivet riveting, drum type blind rivet riveting, and the like.
Second, according to the nature of the matching of the nail and the hole after riveting
1. Interference fit riveting
Before the riveting, under the condition that the nail and the hole are matched with the gap, the upsizing of the nail rod is appropriately controlled during the riveting, so that the hole wall is swollen and swollen, and a relatively uniform interference amount is formed after the riveting.
The interference fit riveting includes common rivet interference fit riveting, headless rivet interference fit riveting and crown rivet interference fit riveting.
2. Non-interference fit riveting
Riveting of a relatively uniform amount of interference cannot be formed.
3. Classification of positive workpieces when riveting
Double rivet
The riveting is completed by approaching the workpiece from both sides.
Double-sided riveting mainly includes: ring riveting in ordinary riveting, sealing riveting and special riveting, and high riveting riveting riveting in rivet-type.
2. Single-sided riveting
Riveting is done only from one side of the workpiece.
Single-sided riveting mainly includes: threaded core high-resistance rivet riveting, threaded hollow rivet riveting, wire drawing blind rivet riveting, drum type blind rivet riveting, lantern blind rivet riveting, light-drawn blind rivet riveting.
