Definitions

  • the present invention relates to an attachment for punching polygon holes and a tool unit that can be used for this purpose. Furthermore, the invention relates to a method for punching polygon holes and a method for attaching blind rivet nuts and / or screws.
  • blind rivet nuts or screws In many cases it is necessary to carry out a blind riveting process because there is only access from one side (e.g. with hollow profiles). In particular when using blind rivet nuts or screws, it is necessary to prevent unintentional loosening of the connection, in particular rotation about the longitudinal axis.
  • the blind rivet nuts or screws are provided with a polygon section which is inserted into a correspondingly shaped opening.
  • hexagonal shapes have mainly been used in the prior art, although any other cross-sectional shape preventing rotation could also be used.
  • These polygon holes are usually produced by drilling a round hole and then reworking this hole using a punch to obtain the polygon shape.
  • One embodiment is a hand-operated stamping tool.
  • This punching tool is provided with three slots that are offset by 120 ° to each other, each halving one of the key surfaces.
  • the punching tool is designed as a tubular body and has a cone at its front end. As a result, this tool tappet can be inserted into the center of the round hole, and radial slit compression can take place. As soon as this front piece of the tool plunger is inserted through the hole, it can spring back outwards due to an annular groove, so that a kind of locking takes place on the hole. The hexagonal cutting edges of the punching tool then rest on the back of the workpiece.
  • a pneumatically or hydraulically operated device is used for this process. This is a custom-made product that is tailored to this application.
  • the subsequent blind riveting of the rivet nuts or rivet screws is then carried out using a commercially available setting tool.
  • These setting tools can be driven in different ways (hydraulic, pneumatic, electrical, etc.). They usually all have a mandrel, which is provided with an external or internal thread end section to accommodate the rivet nuts or rivet screws.
  • the invention is based on the object of bringing about an improvement in the area of punching polygon holes, in particular for a subsequent blind rivet.
  • This task is solved on the one hand by providing an attachment for punching polygon holes.
  • This attachment device has a displaceably held tool plunger, which comprises a punching area designed to be radially spring-loaded. Furthermore, the attachment has a locking device for preventing the radial compression of the punching area at least during the punching process and an adapter connection for releasably coupling a mandrel of a rivet setting tool to the tool plunger while simultaneously actuating the locking device.
  • a punching device for polygon holes is designed as an attachment for a rivet setting device.
  • This offers the possibility that the drive for the attachment is carried out by the existing rivet setting tool.
  • the attachment for example, has to have a hand-operated lever mechanism nor its own drive unit, since one is provided by the rivet setting device.
  • the adapter connection is then designed in accordance with the desired coupling to the available rivet setting tool.
  • a special feature is that the coupling device actuates the locking device at the same time.
  • the attachment is, for example, inserted by hand into a pre-drilled hole and then the rivet setting tool is coupled to the adapter connection. The locking and the subsequent punching of the polygon hole can be carried out in one work sequence.
  • one and the same rivet setting tool can be used for the subsequent rivet setting process in the previously made polygon hole.
  • the attachment can be made very compact due to the lack of its own drive, so that it can also be in or on one Tool belt can be accommodated. This offers enormous advantages for the user compared to devices to be carried separately for punching the polygon holes.
  • the adapter connection can preferably have a coaxially arranged connection thread as a coupling component for the pulling mandrel of a rivet setting device.
  • This embodiment is particularly suitable for rivet setting tools for setting blind rivet nuts or screws.
  • the mandrel is provided with an internal or external thread, so that the adapter connection has a corresponding mating thread.
  • screwing into the connection thread of the adapter connection fits very well with the normal movement sequence of conventional rivet setting devices, so that no other movement sequence has to be provided on the rivet setting device in this regard.
  • the tool plunger can be designed as a hollow plunger with an axial bore, in which a mandrel which can be pushed in is arranged as part of the locking device, the mandrel extending to the adapter connection and being axially displaceable into the punching region of the tool plunger by the coupling process of the pulling mandrel of a rivet setting device is designed.
  • This is a very simple variant of the locking device, in which the preferably slotted punching area is threaded radially by filling the central bore with an additional tool component, the mandrel.
  • the dimensional accuracy of the polygon hole to be punched can also be very well maintained by these measures.
  • the mandrel can preferably extend at least into the region of the connection thread in the tool plunger.
  • the dome can already be pushed forward by attaching a mandrel.
  • the final advancement then takes place, for example, by screwing the mandrel to the connecting thread in the tool tappet, so that the mandrel is pushed into a predetermined position and securely locks the punching area. This could be done at the associated front end appropriate centering aids of the dome and the mandrel of the rivet setting tool are available.
  • the locking device can comprise a pretensioning device which presses the mandrel into an unlocking position.
  • Suitable are e.g. Common helical compression springs with a suitable spring characteristic. The mandrel then returns to its starting position after each punching process.
  • the adapter connection can be designed as an adapter slide that is detachably connected to the tool plunger. This offers the possibility of both exchanging the tool plunger with the punching area and maintaining the adapter slide and also arranging different adapter slides on one and the same tool plunger.
  • the adapter slides can be equipped with different thread sizes, so that they can be easily adapted to the rivet setting tool available. This modular design gives enough space for a wide variety of possible combinations.
  • a tubular housing can be provided, in which the tool plunger is displaceably guided with the adapter connection, at least part of the punching region of the tool plunger projecting axially.
  • the housing protects the entire interior structure and can be designed so that it is very easy for the user to grasp. Furthermore, markings or markings as well as projections on the housing could be provided which specify the position of the polygon on the punching area of the tool plunger, so that the user has an alignment aid.
