Pop rivets can be used to connect wood, metals, or even plastics, and they can be made of specific materials for specialty applications such as when additional strength or corrosion resistance is needed. Lightweight manual pop rivet tools are ideal for simple tasks such as joining metal sheets or thin materials. If you need to repair a metal panel or connect two pieces of acrylic, for example, a manual pop rivet tool can probably handle the job.
Most manual tools have a squeeze handle that sets the pop rivet, and for tougher jobs, you can use a manual tool with a longer lever handle to apply more force. In such cases, you need a power pop rivet tool. For industrial applications, such as manufacturing or where you have to set multiple pop rivets quickly, a more appropriate option might be a hydraulic or pneumatic pop rivet tool. For hobbyists or professionals who use rivets for simple jobs and repairs, having a manual pop rivet tool handy is the way to go.
For example, if you need to repair a truck bed or do some other automotive repair, a short-handled hand rivet gun will probably do the job. If you use a handheld riveter for bigger jobs or to install multiple pop rivets, your hands and arms will surely become tired. The rivet grips the material with friction and not with a second head, while the head at the other end grips the object that is connected to the material.
Grooved rivets are best for construction, metalworking, and furniture manufacturing, as well as electrical equipment and injection molded parts. Multi-grip rivets are similar to standard rivets but have indents located on the rivet body. The indents expand and provide multiple grips when the mandrel is pulled through the body.
These rivets are for fastening metal to plastic and plastic to plastic. The multiple grips on the body of the rivet are forced against the material being riveted as the mandrel is pulled through. Multi-grip rivets are suitable for use in the automotive, construction and metal industries, and in electrical appliances, furniture, electronics, ladder manufacturing and air conditioning and heating.
Soft rivets are identical to standard rivets. However, the body and mandrel are manufactured from a softer metal, which tends to be an aluminum alloy. The mandrel breaks off with much less force than other types of rivet so it applies the right amount of pressure to fasten brittle materials without them becoming damaged.
These rivets are for use when fastening metal to plastic, metal to wood, metal to fibreglass, plastic to plastic and metal or plastic to soft materials with low resistance. The soft rivets can be used in furniture, packaging, plastic components, containers, plastic and construction work. As well as being available in a number of body designs, blind rivets can also have different types of head. The dome head provides enough bearing surface for it to be used to fasten a variety of materials, except extremely smooth and brittle materials such as plastic.
This is because this type of head applies more pressure closer to the hole that has been drilled which can damage softer materials. The bearing surface is the contact between two materials.
In this case, it is the area under the head of the rivet which makes contact with the material being fastened. The large head offers double the bearing area of a dome head rivet. This provides great resistance and is ideal for fastening brittle or soft materials to rigid support materials. The pop rivet was invented in Scotland shortly before World War I. In the United States, inventors such as Carl Cherry and Lou Huck experimented with other techniques for expanding solid rivets, such as the pull-through method.
By drilling a hole through a rivet and expanding it with a mandrel, these fastener pioneers eventually developed a cost-effective rivet that could be installed in structures where fasteners were accessible from one side only.
In , the first U. It was quickly adopted by the aircraft industry. The device enabled mass production of military aircraft during World War II. It's actually a really ingenious invention! Before blind rivets were invented, you had to have access to both sides of your work piece. For complex machinery, this could be a huge hassle as it would often mean that whatever you wanted to repair had to be disassembled.
The process for riveting is based on a pulling motion, and the fact that the rivet is made from a soft metal. The action of pulling the mandrel through the tube of the rivet flares out the "blind" side of the rivet, which is on the other side of the work pieces.
This flaring action binds the two work pieces between the rivet head and the flared blind end. Over the years quite a few types of blind rivets have been developed for different uses and to side-step patents held by competing companies.
Rivets also come in different materials and head types to suit your specific needs. That being said, it is likely that your needs will be fulfilled by a simple Aluminum rivet with a domed head. Rivets come in different gauges, which means that you have an assortment of options. Select the smallest gauge that you think that you can get away with.
The size of the rivet will define the hole that you will need to drill. You'll start by drilling a hole through your two work pieces. I find that clamping the two pieces together first ensures that the hole that I drill is exactly where I want it. Remember to use a center punch first because a bit will tend to wander on metal without some sort of initial guide.
Select a rivet length that will fit your work pieces. You can measure the depth of your materials with a good caliper. The length of your rivet should be at least 1.
So if you are riveting together two pieces of aluminum which are each 3mm, you should add them together and multiply by 1. The blind rivet gets inserted into the riveting gun via the mandrel. The head should be pushed firmly up against the end of the gun. The "nub" end of the rivet will be pointing away from the gun. The rivet pliers are pushed on to the pin of the rivet and the handles are pulled together. As this happens the pin head is pulled into the rivet and the end of the rivet is expanded.
Explain with notes and diagrams how you could joint two pieces of thin aluminium sheet.
