Stainless Steel Bullet-Shaped Rivets

Product introduction:

Bullet rivets, named because their shape resembles a bullet, are efficient and economical mechanical fasteners used for single-sided riveting. It is widely used in the connection of thin plate materials due to its convenient installation and high reliability. The rivet consists of a rivet body and a nail core pre-installed in it. When installing, insert the rivet into the pre-drilled hole and use a special rivet gun to pull the nail core. The head of the nail core will squeeze the rivet body, causing its tail to expand and deform, forming a huge drum head on the back of the material, thereby firmly clamping the workpiece between the rivet head and the drum head. After the installation is completed, the nail core will be pulled off at the preset breaking point to complete the entire process. Bullet rivets are usually made of aluminum alloy, steel, stainless steel and other materials, providing good strength and corrosion resistance. It is generally used for the permanent connection of various metal sheets, plastics and other materials, especially in the fields of chassis cabinets, sheet metal processing, auto parts, home appliance manufacturing and equipment shell assembly. It is an ideal solution to achieve fast and reliable single-sided riveting.

 

Product features

1. Single-sided construction, easy to operate

This is its most significant advantage. When installing, you only need to use a special riveting gun on one side of the workpiece, without entering the back of the workpiece, which greatly simplifies the operation process. It is especially suitable for connecting structures that are closed or can only be accessed from one side.

 

2. Efficient and firm, anti-seismic and anti-loosening

The riveting tool breaks the nail core and causes the tail of the rivet body to plastically deform and expand, forming a drum head with a large dry hole on the back of the workpiece. This mechanical cold forming process creates a strong clamping force and the connection points have excellent resistance to vibration and loosening.

 

3. Strong applicability and various materials

The rivets themselves can be made of a variety of materials, such as aluminum alloy, steel, stainless steel, etc., to match the strength and anti-corrosion needs of different base materials. Its through-hole design requires simple plate preparation and is widely used in the connection of metal, plastic and other thin plates or profiles.

 

4. Cost-effective and reliable process

The installation tools are simple, the cost is low, and the installation process is fast. The nail core breaks at the preset breaking point, ensuring the consistency of the clamping force and the repeatability of the process, which is conducive to achieving high-quality, high-efficiency mass production.

 

Product application

1. Chassis cabinet and sheet metal structure

Application scenario: This is the most classic application field. It is widely used in the assembly of various sheet metal enclosures such as network cabinets, server cases, electrical control boxes, distribution boxes, etc. Advantages reflected: In closed or semi-closed box structures, the characteristics of single-sided construction make it the only efficient and economical connection method, which can quickly secure panels, brackets, guide rails and other components.

 

2. Automobiles and Transportation

Application scenarios: Used to connect the skin and frame of passenger cars and truck compartments, as well as to fix interior panels, insulation layers, chassis components and ventilation ducts. Advantages: It can adapt to the connection of different materials (such as steel and aluminum), and provides excellent anti-vibration performance to prevent loosening due to vibration during vehicle driving.

 

3. Home appliances and electronic equipment manufacturing

Application scenarios: Used to fix air conditioner casings, washing machine panels, refrigerator internal brackets, oven casings, and metal or plastic casings of various electronic devices. Advantages: The installation speed is fast, suitable for automated or assembly line production, and the riveted appearance is smooth and does not affect the beauty of the product.

 

4. Building decoration and facilities

Application scenarios: Used to fix aluminum alloy doors and windows, curtain wall panels, ceilings, sunroom frames and the installation of various signs and signs. Advantages: Easy to install, reliable connection, able to withstand wind load and other external forces, and some materials (such as stainless steel) have good outdoor corrosion resistance.

 

5. Other industrial fields

Application scenarios: It is also commonly used in the manufacturing of ventilation ducts, agricultural equipment, toys, sports equipment, packaging boxes and other products.

 

FAQ

Q: How do bullet rivets work?

A: Its core is single-sided riveting. When installing, put the rivet into the pre-drilled hole, use a special rivet gun to clamp the nail core (mandrel) in the center and pull. The enlarged head of the nail core will squeeze the rivet body, causing its tail to expand and deform, forming a "drum head" larger than the hole diameter on the back of the workpiece. When the pulling force reaches the set value, the nail core will be pulled off at its weakest "breaking point", thereby firmly clamping the workpiece between the rivet head and the drum head.

 

Q: What tools are needed to install bullet rivets?

A: A special rivet gun must be used. There are three main types: manual, pneumatic and electric. Manual rivet guns are suitable for installing low-volume, low-strength rivets (such as aluminum rivets); pneumatic and electric rivet guns are suitable for high-volume operations or installing high-strength rivets.

 

Q: Can bullet rivets be disassembled?

A: It is a permanent fastener and cannot be removed without damage once installed. The conventional disassembly method is to use an electric drill to drill out the core stump in the center of the rivet, and then knock out or eject the remaining rivet body. This will damage the original rivets, requiring new rivets to be replaced and reinstalled.
