![]() ![]() Read along as we cover the pros and cons of each type or riveter. While not all rivet guns were made equal, it is easy to identify the type of rivet gun needed for an application. Not only are there many things to call a rivet gun, there are also many varieties. These tools are commonly referred to as rivet guns, riveters, rivet tools or riveting tools. #RIVET TYPES INSTALL#Knowing how rivets work is great but how do you install them? A rivet requires a tool that keeps the hat of the rivet firmly pressed against the installation surface while simultaneously pulling the mandrel away from it. It is common for this type of rivet to be used when you cannot get to the back of an installation earning this fastener the name of Blind Rivet. Once the deformed portion grips against the back of the installation material the mandrel snaps leaving a clean finished application. As the mandrel is pulled through the body, it deforms the back of the body. The mandrel goes through the inside of the body and gets pulled during installation. POP Rivets are comprised of two pieces: the body and the mandrel. Blind rivets, often referred to by the brand name POP rivets, are an incredibly useful fastener designed to hold two materials together with a clamping force. In the past four decades aluminum and titanium rivets have been used in the aerospace industry very effectively.In order to understand rivet guns, the first thing to do is understand how a rivet works. Materials for some special-purpose rivets are aluminum and copper. Standards include acceptance tests for cold and hot ductility and hardness. Standard material for rivets is open-hearth steel (containing manganese, phosphorus, and sulfur) with tensile strength of 310 to 380 MPa. In the explosive type an explosive charge in the point is set off by a special hot iron the explosion expands the point and sets the rivet. In the mandrel type the rivet is set as the mandrel is pulled through. They are available in many designs but are of three general types: screw, mandrel, and explosive (Figure R.2). Special-purpose rivets are tinners’ rivets, which have flat heads for use in sheet-metal work cooper’s rivets, which are used for riveting hoops for barrels, casks, and kegs and belt rivets, used for joining belt ends.īlind rivets are special rivets that can be set without access to the point. Large rivets (13 mm and over) are used for structural work and in boiler and ship construction with heads as follows: roundtop countersunk, button (most common), high button or acorn, pan, cone (truncated), and flattop countersunk.īoiler rivets have heads similar to large rivets with steeple (conical) added but have different proportions from large rivet heads in some cases. The fillet under the head may be up to 0.8 mm in radius. These rivets are commonly made of rivet steel, although aluminum and copper are used for some applications. Small rivets (11 mm and under) are for general-purpose work with head forms as follows: flat, countersunk, button, pan, and truss (Figure R.1). For high-grade work such as boiler-joint riveting, the rivet holes are drilled and reamed to size, and the rivet is driven to fill the hole completely. In forming the point, a hold-on or dolly bar is used to back up the manufactured head and the rivet is driven, preferably by a machine riveter. ![]() The first head is called the manufactured head and the second the point. ![]() A rivet is inserted through aligned holes in two or more parts to be joined then by pressing the protruding end, a second head is formed to hold the parts together permanently. A rivet is a short rod with a head formed on one end. ![]()
