DEPRAG STATIONARY SCREWDRIVERS

STATIONARY SCREWDRIVERS WITH ELECTRONIC DRIVE fulfills the highest demands for the industrial assembly process. DEPRAG screwdriver spindles are extremely small and are simple to integrate and offer a high degree of flexibility by being freely programmable process reliable through comprehensive analytics.
THE PNEUMATIC SCREWDRIVER SPINDLES feature an extremely robust design and the highest torque accuracy. Using our special designed shut-off clutch, guarantees a torque accuracy of 3% standard deviation, independent from the screw joint. In many cases and under suitable conditions, it is possible to achieve an even higher torque accuracy and a Cmk value of ≥1.67 even at a tolerance of ±10% can be reached. it is possible to additionally control the screw-depth and the shut-off of the screwdriver.

FEEDING TECHNOLOGY

FOR MANUAL AND STATIONARY USE
The timely presentation of the necessary fastener for a particular product assembly is an essential component of the productivity and availability of your assembly process.
DEPRAG feeders supply components as well as their necessary fasteners, in the desired volume and orientation, efficiently and accurately positioned.
Feeding Technology guarantees the presentation of screws, nuts, rivets, pins, washers, o-rings and other symmetrical and asymmetrical components, and assuring the highest reliability of our feeding systems.
We offer a well-engineered and proven line of standard and customized solutions:
For the manual and stationary use,
Standardized sizes of fasteners from M1 to M16
Single, double or multiple feeding Vibratory, Sword (segment) or Tape-on-Reel systems
Transport through a feedhose or by Pick-and-Place procedure

SEQUENCE CONTROLLER AND PROCESS MONITORING

SCREWDRIVING CONTROLLER
Besides the screwdriver, the screwdriving controller is an essential component of the electronic screwdriving system. According to the parameterized screw-tightening process, the controller controls the EC-drive of the Screwdriver, evaluated the measuring signals and provides all necessary operator- and documentation functions.
AST5 and AST11 are based on the exact motor-current measurement, the EC-Servo system with the controller AST30-31 and AST40 evaluates the signals of the transducer integrated in the tool.

FUNCTION CONTROLLERS – FC
Function controllers are used to the increase of the process reliability in the manual screw-assembly. They allow the supervision of each individual tightening-process and guarantee the completeness of the screw-connection on a given product.

Deprag Feed Module (DFM)

• Screw system with automatic feed.
• Smaller, lighter and smarter version, versatile and suitable for both manual and stationary screwdriving applications.

• Constant pressure force.
• Optimized cycle time.
• For stationary and manual applications.
• Suitable for lightweight robots.
• The screwdriving process can be horizontal or vertical, depending on the application!

Take the workload off your employees with the ergonomic handheld screwdriver with automatic screw feed, which enables easy handling and fatigue-free working!

Advantages of Deprag Feed Module

• Ergonomic: uncomplicated handling and fatigue-free processing due to the integrated bit stroke
• Process reliable: constant pressure force as a result of the integrated bit stroke; automatic documentation of processing data.
• Efficient: optimised cycle time; automatic feeding of fasteners; fast positioning of the screw due to the integrated lock stroke; no PLC required; integrated sequence controller via the feeding system.
• Flexible: can be combined with electronic or pneumatic drives; all screwdriving parameters are freely adjustable; suitable for both stationary and manual applications.
• Maintenance friendly: tool-free quick-change system for bit and positioning sleeves.
• Suitable for lightweight robots: low weight of the DEPRAG Feed Module makes it ideal for applications which use lightweight robots.

ADAPTIVE DFS – Screwdriving system for flow-form assembly

Robot-assisted assembly system for controlled, automated flow-form assembly

• Flow-form screwdriving systems enable high-quality non-cutting assembly without the need for component preparation, such as pre-drilling or punching. The DEPRAG Fastening System with controlled electric drive for the feed and screwdriving process is the ideal solution for controlled, automated flow-form assembly.
• Using the patented technology of the ADAPTIVE DFS, extensive parameterisation options are available, irrespective of fastener and component tolerances. This ensures a high degree of flexibility for the processing of different materials and material combinations in flow drill fastening.
• Less space required due to shorter design of rotary separator and downholder
• Reduction of cycle time by up to 50%  due to automatic pre-engagement of the screw during the robot movement with flow drill screws.
• Simple connection to your company network and hardware, such as tablets and notebooks as a result of hardware and software optimisations.
• Cost saving and shorter conversion times thanks to a pre-assembled cable set and extendable cable supplied as standard.
• Easy integration into existing assembly lines through standardisation of control cabinet types and integrated booster extension.
• Fully compatible with Deprag Cockpit.
• Highest process reliability.
• Optimised funnel forming.
• Flow drill screws avoids thread damages.
• Less stress on fastener and product.
• Reduces set-up time thanks to flow drill screws.
• Designed for new materials, fasteners and joining methods.
• Optimally prepared for end-of-life recycling.

TOOL CHANGER– Maximum flexibility in assembly through automated tool changing

• The tool exchange system (Tool Changer) is a new additional feature from DEPRAG for electric and electronic DEPRAG stationary screwdrivers.
