orbital riveting process

On the downside, it is claimed that the grain structure of orbital formed heads is not of the quality obtained with twin-spin rolls and radial forming. Orbital riveting is a low force cold forming process. riveting heading orbital forming tools direction variety suit wide applications assembly courtesy systems drawing If you install multiple rivets per workpiece, you need to consider a multi-head or multi-hit impact machine.

One difference is that the control of a joint can be held within limits that are slightly better than orbital forming. ZL However, these are primarily limited to the cost of the equipment and the cycle time (typically 2 to 15 seconds). However, if the rollers are mounted such that they can be moved inwards, it is possible to crimp a component almost anywhere along its axis. 0000028041 00000 n

The peen does not rotate on its own axis. A warm orbital forming process also exists. When emergencies happen, a proactive inventory strategy can save valuable time. Many believe that either orbital or radial forming yields superior results to the other in specific applications. _^ 8IYd&rS7vl3qL0IkqUGXn"RIMt*bN{s;)RzSNsaLoe.*$k(czVD x1GulDOmJcJKAw9&9{vM)J/ The package includes a load cell for feedback on force applied while forming, and a LVDT or linear variable differential transformer, which gives feedback on the distance the peen tool traveled to form a rivet.

Because of the nature of the process, it is fair to say that there has been relatively little research and development in the field of impact riveting over the past 40 years. riveting This rivet/forming solution uses heat and force to form rivets or part tenons. While this is partly true, impact riveting remains the optimum fastening method for many applications, such as leatherwork, tools, toys, kitchen utensils or general hardware, where the speed of the process is attractive and there is no justification for a high degree of control over the process or a need for particularly tight tolerances. In such applications, the term orbital riveting is often used instead of spin riveting. xAi[Ane CB.hr#biqVu@|S2%F# Orbitform's Engineers deliver another machine solution for an HVAC company. With years of experience, we can help you get the machines your business needs! Heres what you need to know about incorporating orbital riveting into your manufacturing process. endstream endobj 30 0 obj <> endobj 31 0 obj <>stream However, both sides of the assembly must be accessible. This movement progressively collapses the rivet or tenon shank down onto the upper material with each rotation, permanently forming a rivet head in the process. 0000022286 00000 n Orbital tooling is generally set up to produce extremely tight assemblies where no movement is acceptable. Medium- and heavy-duty machines run at 900 rpm and 1,200 rpm. The working end of the peen passes over the end of the rivet shank on a path that is an 11-loop rosette. %PDF-1.3 % Assemblers generally want to eliminate loose rivets from an assembly operation. In all cases of roller forming described so far, the rollers are mounted in fixed positions. If the diameter of the rivet form is increased, a larger peen can be used to form a ring of material, perhaps to leave a clear diameter through which another component can pass. And because the machines can be set to precise pressures, it has been used successfully on assemblies containing Bakelite, ceramics, glass and other brittle materials. Become an informed consumer! 0000032452 00000 n Using a peen tool positioned at a 3, 4, or 6 degree angle and mounted on a rotating spindle, it maintains a line of contact on the workpiece and gradually kneads the material to a desired form. orbital forming process riveting figure 50 0 obj <>stream First, orbital riveting is a cold-forming process, which means that no heat is required. Compared with impact riveting, there is no risk of unwanted damage to the parent material, and the gradual forming process does not crack or otherwise damage the rivet. Design, CMS, Hosting & Web Development :: ePublishing. Unlike welding, it is straightforward to join dissimilar materials, plus there is no heat affected zone, no weld spatter and the finished surface is smooth, with no sharp edges. At Orbitform, we developed a unique riveting process called Hot Upset. Impact riveting, where a solid or hollow rivet is formed with a single blow, is one of the oldest imaginable joining methods and, therefore, is often considered to be low technology and only suitable for low-value, high volume assemblies or those where tolerances are not particularly tight. Most thermoplastics lend themselves well to the process. This includes virtually all grades of mild steel, most alloys and nonferrous metals, such as aluminum, brass and copper. The design called for two rivets to be formed, both of different sizes and requiring different torque specs. It is therefore possible to indelibly mark a part number, logo, symbol or date code on the assembly. riveting orbital riveting orbital 0000011461 00000 n Normally the peen will have a smooth surface in order to produce a near-polished finish on the component. However, there are some related processes, namely spin riveting, orbital riveting and orbital forming, that are experiencing a resurgence in interest, partly as a result of recent developments in real-time process control technology. riveting rivet The process is quiet, consumes little energy, and produces high-quality joints and heads, at high cycle speeds.

Design guidelines for rivet diameter and length to align with the orbital or impact riveting process, After 22 years of service, Phil Sponsler retires as President of Orbitform; Jake Sponsler promoted. 0000003701 00000 n The peen rotates as the tool is orbiting the rivet. riveting machine pneumatic monitoring process orbital metal Other industries have discovered the benefits of orbital and radial forming, too. Partnering with Orbitform can simplify this process. When changes in production happen, retooling existing equipment is a great option that can make a massive difference in Return-on-Investment. 0000001906 00000 n Recently, a customer contacted us after a machine shipped via cargo ship through the Atlantic Ocean was mishandled and left crated for an extensive amount of time. Orbital forming is a remarkably versatile process if clear access is available at the face to be processed.

Forming pressure is applied following the rosette pattern, so the pressure line on the peen moves repeatedly through the common centers of the peen and the rivet shank. The process of the peen pressing against the rivet shank spreads the rivet material radially outward, radially inward and tangentially overlapping. 0000021134 00000 n The angle between the peen axis and spindle axis varies continuously between 0 to 6 degrees. Orbital forming takes the concept of orbital riveting a stage further. If the rivet passes through, say, a polymer or soft metallic component, a load-spreading washer can be used beneath the head of the rivet which might also be shouldered. We're a small company with big ideas. The main advantage of radial forming is that is does not deform the molecular structure of the metal as much as other riveting processes. orbital riveting radial machines hydraulic multi head machine ". This gradually forms the rivet head into the desired shape, the actual geometry of which depends on the rivet, peen and process parameters. 0000029032 00000 n 3). Radial forming was developed in Europe in the 1960s and is often confused with orbital forming. Tune into this exclusive panel discussion featuring executives from four of the nations top suppliers of fastening tools: ASG, DEPRAG, Desoutter and Panasonic. Unless a large mass of material is being formed, the workpiece is normally cool to the touch. Of course, spin riveting has its drawbacks compared with impact riveting. Manufacturers can ensure they purchase the right assembly equipment, validate their assembly design, or assemble low volumes of parts or prototypes by utilizing Orbitform's Solutions Lab. Orbital and radial forming has been used extensively in the automotive industry for years. Companies such as DMG Engineering, of Pershore, UK, can assist with component and assembly design. The tools can be adapted to work in close quarter. 0000001486 00000 n In most assemblies that are joined with threaded fasteners, the cost of the fasteners is not as important as the cost of installing them. Both processes can be used on any material that can be cold-worked. riveting contract riveter purchase process assembly single why Almost any diameter can be formed, from about 2.5mm to 40mm. However, there is another related process that can be used around the periphery of an assembly with, say, a thin metallic sleeve that needs to be formed to retain an end cap. endstream endobj 17 0 obj <> endobj 18 0 obj <>/Font<>>>/Fields[]>> endobj 19 0 obj <>/ExtGState<>/Font<>/ProcSet[/PDF/Text/ImageC]/XObject<>>>/Rotate 0/TrimBox[0.0 0.0 595.276 793.701]/Type/Page>> endobj 20 0 obj <> endobj 21 0 obj <> endobj 22 0 obj [/Separation/Black 23 0 R 43 0 R] endobj 23 0 obj [/ICCBased 42 0 R] endobj 24 0 obj <> endobj 25 0 obj <> endobj 26 0 obj <> endobj 27 0 obj <>stream Learn how to leverage our Service Team to support your assembly equipment. Orbital forming is a cold forming process using a peen tool held at a fixed angle to create a sweeping line of pressure around a rivet or tenon. riveting Orbitforms engineers reviewed the design Orbitform is excited to announce the acquisition of Diamond Precision Tool Group. Roller Forming can be an alternative to crimping when quality issues arise. Like orbital forming, the radial process produces heads on rivets, pins and posts.
