Henrob Die ChangerAdding flexibility to your manufacturing by providing theability to change dies automaticallyIndustrial Assembly SolutionsInstall a variety of joints from a single setting systemThe Henrob Die Changer has been designed to provideadditional flexibility to your Henrob self-pierce riveting (SPR)equipment. The ability to change dies automatically results ina higher variety of riveted joints produced by a single settingsystem.Additionally, in conjunction with the digital die check camera,the die changer can replace broken dies or dies that havereached their designed life, thereby improving the overallperformance of equipment and reducing the level of interventionrequired by OEM maintenance teams.The die changer can be applied to most automated SPRproduction cells, typically those configured with more than onerivet type or otherwise in cells with the primary purpose of amaintenance tool for exchanging and replacing dies.Benefits at a glanceImproved efficiency – Fastautomatic die changing andmultiple joints in the sameoperationReduced total cost ofownership – More processescan be performed at onestation without the need formultiple robots or systemsEnhanced user experience –Operators do not need toenter an automated cell andminimal manual preventativemaintenance is requiredHenrob Die Changer / 01 Introduction

Henrob Die ChangerFeatures & benefitsThe Henrob Die Changer offers the best-in-class changing time of less than 5 seconds The die changer can be used to either replace worn / broken dies or allow die changing to adifferent type to improve flexibility in the rivet joining processThe dies are locked into the die post so full manipulation of the equipment on the end of a robot isnot a concernOptions are available to use diameter 20mm dies which have extended life at higher forcesThe compact footprint of the die changer allows it to fit easily into your production cellPoka-yoke packaging of the dies will become available in 2019Die head availabilityTarget marketØ20 Die head - 5mm rivetsØ18 Die head - 5mm rivetsThis product is intended to increasethe flexibility of highly automated andcomplex production lines. It is alsouseful in prototype environments orin SPR systems configured with onedie type to be replaced at scheduledpreventative maintenance intervals.Ø18 - 5mm Poka-yoke packaging optionavailable TBDCurrently only one SPR control paneland robot can be configured per diechanger. In the future, theAtlas Copco SPRdevelopment team willbe adding a softwarefeature that will allowmultiple robots toexchange dies onone die changer stand.The Die Changer communicates directly with the robot via Ethernet –a robot command/signal bitmap is provided to control the Die Changerindependently of the SPR setting systemHenrob Die Changer / 02 Features & benefits

Henrob Die ChangerDie changing actionDie retentionpinStarting positionThe die is locked into the die post andthe die ejection assembly is mountedon the die ejection cylinder, engagingwith the mechanism inside the diepost to either release or lock the die inplace.Die postC-frameDie ejectionassemblyDie ejectioncylinderThe die ejection assembly (blue) positioned below theC-frame as it enters the docking areaDie contactAs the die ejection cylinder extends, theejection assembly (blue) moves forward intothe C-frame and die post.The die ejection assembly makes contactwith the die retention pin (red) and raises thedie above the post to allow it to be capturedby the gripper assembly.Gripper mechanism lowers to remove die from postDie exchangeDie retention pin (red) hits a hard stop allowing theinternal pin of the die ejection assembly (blue) tocontinue its travel. The internal pin presses the plunger onthe die retention pin actuating the ball-lock mechanismand allowing the die to be removed.As the die ejection assembly lowers, the mechanismworks in the reverse direction and locks the die in place.With the die locked in place, the SPR tool head has norestrictions on articulation and movement.Die unlocked and ready to changeHenrob Die Changer / 05 Die changing action

Once the C-frame sizes are known, a second level of selection can be configured. Dueto the vast array of SPR setting configurations there are a number of fitting arrangements thatneed to be made to suit each C-frame design.Inquire or request that the die type you need is released, as the shank of the die is not the sameas a conventional die shank and not all dies are currently available.Note: The die changer system can not work with a wear plate. There is a minimum die postheight of 40mm.Utilizing the Die Changer requiresreplacing a standard die post witha quick-change die post assembly -the external envelopes are generallyunaffected.Henrob Die Changer / 06 Configurations
