As a manufacturer of industrial screwdriving technology, DEPRAG develops precision solutions for demanding assembly tasks: from manual screwdriving to fully automated and documented screwdriving processes.
Our portfolio includes handheld screwdrivers, stationary screwdrivers, intelligent system solutions, and torque measurement equipment. Depending on your application, we combine screwdrivers, controllers, process monitoring, and feeding technology to create cost-effective industrial screwdriving systems.
Working closely with you, we develop a solution that is precisely tailored to your screwdriving application, production environment, and quality requirements.
What is industrial screwdriving technology?
Industrial screwdriving technology involves far more than simply tightening a screw. To ensure that a screw joint performs its function reliably over the long term, the screwdriver, tightening method, fastener, component, and process parameters must be precisely coordinated.
Depending on the application, the screwdriving process is controlled and monitored using torque, angle of rotation, screw-in depth, or other measured variables. Modern screwdriving systems evaluate the result and provide relevant process data for quality assurance and traceability.
This creates reproducible joints – from manual assembly to automated and connected screwdriving processes.
From manual assembly to automated screwdriving systems
The requirements for industrial screwdriving processes vary depending on the assembly concept. At manual workstations, the focus is on ergonomics, flexible operation, and reliable shut-off. Automated applications, on the other hand, require the precise coordination of screwdriving technology, controllers, feeding, and process monitoring.
DEPRAG offers solutions for every level of automation:
- Handheld screwdrivers for flexible assembly workstations
- Stationary screwdrivers for stationary and automated applications
- Industrial screwdriving systems for monitored screwdriving processes
- Measurement equipment for testing and quality assurance
DEPRAG screwdriving solutions & technologies
Industrial screwdriving technology is used in a wide range of production concepts. At manual assembly workstations, the focus is on ergonomic operation and flexible handling. Automated applications require the precise coordination of screwdriving technology, component positioning, feeding, and process control.
DEPRAG supports both approaches – from individual assembly workstations to automated screwdriving stations.
The quality of a screw joint depends largely on selecting the appropriate tightening method. Depending on the screwdriving application, torque, angle of rotation, screw-in depth, or combined measured variables can be used to control and evaluate the process.
Modern screwdriving systems detect deviations and automatically evaluate the screwdriving result. This ensures reproducible processes and reliable quality assurance. Our guide to VDI/VDE 2862 explains the requirements associated with each risk class.
In demanding screwdriving processes, the screwdriver, controller, software, and data acquisition work together as an integrated system.
Screwdriving programs can be managed, process parameters monitored, and results documented. Suitable interfaces allow data to be transferred to higher-level production, quality, or database systems. The DEPRAG Plus screwdriving system combines the AST12 sequence controller with an EC-Servo or EC screwdriver.
To achieve short cycle times and stable automated processes, screws must be reliably separated, presented in the correct orientation, and transported to the screwdriver.
Depending on the fastener, cycle time, component, and requirements for technical cleanliness, different feeding systems and methods are used.
Screwdriving technology can be flexibly integrated into applications with industrial robots, lightweight robots, and collaborative robot systems.
The stationary screwdriver, stoke unit, feeding system, and process control are combined to form a coordinated screwdriving unit. The design is based on component accessibility, cycle time, screwdriving application, and the existing system structure.
In flow-drilling screw joints, the extrusion and thread are formed directly in the component during the screwdriving process. The method enables joining from only one accessible side of the component and is particularly suitable for lightweight structures.
The ADAPTIVE DEPRAG Fastening System dynamically coordinates the screwdriving motion and feed with the respective process.
