Flow-Form Automation by DEPRAG

In assembly areas where access from both sides is not possible, an alternative fastening process is required. In such cases, screw tightening made with flow drilling screws have come to the forefront as a solution to the problem. Flow drilling screws create a high-strength fastener connection and form a process-reliable joint for different types of sheet metals. 

                                                                             Flow-Drill Process
One Cycle incorporates the following processing steps:

  Step 1: Heating

  Step 2: Penetrating

  Step 3: Funnel Forming

  Step 4: Thread Forming

  Step 5: Screwdriving

  Step 6: Final Tightening



The new DEPRAG system is recommended because of its ability to adjust flexibly in places where available space is at a minimum. For those applications, robotic screwdrivers are designed to specifically deal with limited space situations. By using a 1:1 ratio offset gear to offset the drive motor and screwdriving axis to the side, the DEPRAG "FFS" screwdriving system can access screw positions located as little as 10-millimeters (0.393 inches) away from an obstacle! The screwdriving module can be turned in any direction, and simplifies the deployment into any position. It is available with a single configuration with Top-Rear-Left-Right robot mounting capability.

It incorporates an adjustable force from 150 - 3,000 N (34 - 674 pound force). This automation system utilizes already established product lines such as the proven MINIMAT-EC screwdrivers, DEPRAG feeding equipment, as well as its controllers that have proven themselves many times over.
