Actually use the riveting equipment of the situation. The following key points are usually considered when selecting rivets:
Typical application characteristics Case board type Aluminum alloy plate, thick steel plate, plastic plate or sandwich plate Lower strength material Cold rolled thick steel plate or aluminum alloy plate Medium level strength material Hot rolled thick steel plate, extruded plate or forged plate Only low tensile strength materials such as carbon steel, non-ferrous plate aluminum alloy or plastic plate high tensile strength material HSLA steel or DP & TRIP thick steel plate group total thickness of 1mm to 6mm steel, 1mm to 12mm aluminum composite plate Riveted plastic + metal material, aluminum alloy plate + thick steel plate functional car, house non-functional furniture, wooden cabinet, spare parts, etc.
Rivet head way
The selection of the rivet head method is usually applied to the requirements of the riveting characteristics or is considered to be beautiful and elegant. The requirements of the riveting characteristics will be:
Flatness requirements of steel parts after riveting; cutting, detachment and fatigue limit experiments;
Signs may be terminated by mechanical equipment; support a large surface;
Requirements for event processing technology;
Advantages of countersunk head rivets: riveting and shaking one side of the head is very flat; high fatigue limit;
Advantages of round head rivets, pan head rivets and ball head rivets:
Very high tightening force is shown, especially for plastic deformed or thinner metal sheets;
Ensure that the top of the rivet head is accurately positioned, especially if it is for thick or stiff boards;
Highlight the beauty of the riveting point or cover the dents at the root of the rivet;
Unique rivet head method
When self-piercing riveting must be used in conjunction with other processing techniques, it is necessary to consider the application of unique rivet head methods, such as self-piercing riveting anchor bolts, self-piercing riveting
Pins and T-shaped self-piercing cotter pins;
Rivet length and nail rod diameter
The length of the rivet must be combined with the thickness of the riveted board to take into account that a certain length of rivet can cover the board of the necessary category to be thin.
The strength and thickness of the group can be determined by experiments to determine the best length of the rivet. There are two types of rivet diameters: 3mm and 5mm. Choose a suitable rivet diameter.
The specifications are: the tightening force required for riveting; the performance required for riveting; the limitation of the indoor space level; the thickness and strength of the riveted board;
Self-punching rivets
The portable full-automatic self-punching riveting machine uses a belt-type rivet for automatic nailing, and it is said to be used in trouble-free automation technology.
