Press-insertion system in combination with suitable feeding

Press-insertion devices for handheld and stationary assembly tasks

If you have ever punched a hole in a cover or pushed a tack or pin in a wall then you will know how much stress it causes your thumbs. It can be painful if your thumb is strained like this repeatedly over time. There are many applications in industrial production where it is often left to workers to push together fastening elements by hand in order to attach two components. Fitters may repeat the movements hundreds of times per day. For automotive assembly, interior trim is predominantly attached using trim clips, plastic expanding rivets or push-fit panel pins. These fasteners have one thing in common: They must be pressed into a pre-drilled hole to connect two components together. Press-insertion joining processes can be found in many other sectors as well as the automotive industry: from the aviation and aerospace industries or machine building, telecommunication and apparatus engineering up to modular assembly for electronics and vehicle technology.

In order to make the positioning and placement of fastening elements more ergonomic for fitters and to make the assembly process more efficient, manual work stations can be equipped with manually-operated press-insertion devices. These tools support operators, making the process simpler by using an insertion stroke for press-in procedures. In addition, any attachment points which are difficult to access, can be reached more easily using the tool rather than using fingers. The specialists for automated feeding and screwdriving technology, DEPRAG SCHULZ GmbH from Amberg, Germany have developed two press-insertion devices for handheld use: Type EDG with an insertion stroke and type EDGZ with an insertion stroke and additional locking stroke. Both devices are characterised by the convenient ergonomic shape of the handle. The operator guides the entire downstroke of the press-insertion procedure when using type EDG. The pressure exerted by the operator supports the down-pressure. Whereas when using type EDGZ, the operator only effects a short insertion stroke necessary for actual press-insertion. An integrated cylinder performs the locking stroke ensuring that pressure is kept directly on the fastener as it protrudes from the nosepiece. The fastener has no space to retract.

In addition to the manual press-insertion devices, DEPRAG also supplies stationary press-insertion modules. In stationary applications, both the feed and insertion strokes are carried out by cylinders. Sensors, which recognise the features of varied fasteners, can be used to realise innumerable applications, processing rivets, pins, sleeves and balls, as well as asymmetric components. The press-insertion module can also be enhanced with integrated depth sensors, presence monitors and position controls, thereby creating a versatile complete solution for complex assembly applications.
