Case Study: Robotic Press Brake - Automated Metal Bending

Contributed by | Midwest Engineering Systems Inc.

Midwest Engineering Systems Inc. (MWES) provided a Robotic Brake Press Tending System to automate the metal part bending process of a Bystronics Brake Press for a metal fabricator.  The goal is to completely automate the brake press to bend a variety of different parts.

The Challenge:

  • Must be capable of handling as many different parts as possible.

  • Some parts need to be bent in more than one location.

  • Ability to automatically change tooling.

  • Part weights were upwards of 500+ lbs.

  • Our customer provides product to the automotive and military industries and must maintain high quality standards on shipped finished goods as well as throughout the manufacturing process.  

During the proposal stage, MWES performed a thorough evaluation of the current situation to provide a solution option.  In order to achieve all of the project’s goals, multiple solution options were analyzed before a final path was chosen.  

The Solution:

After a review of existing specifications, process data, programs, and interviews with the engineering team, production managers and machine operations, MWES was able to execute a successful solution to our customer. The comprehensive solution included:

  • ABB Robot System

  • Three Robot EOAT’s with Tool Change

    • Capable to handling many parts

    • Automatic tool changer/swivel unit

    • Vacuum/Magnetic Gripers to handle parts

  • BendWare Robot programming software

  • Part squaring table to justify the sheet metal blanks to be formed

  • Part re-grip station

  • Used to re-grip parts between bending cycles

  • Vacuum or magnetic grippers

  • Part present sensors

  • In feed and out feed station including guides and sensors

  • Implemented robot safety equipment, which meets ANSI/RIA standards for robot cell safety.

  • Allows communication with brake press system

  • Discreet electrical interface connected to robot via Ethernet

  • Electrical Enclosure with electrical panels and brake press control interface

  • Electrical & Mechanical Installation and on-site operator training at customer facility.   

  • On-site operator training at customer facility

Impact To the Customer:

The final solution added new features and capabilities to the press brake process.  Some key enhancements are:

  • Increased productivity.  Machine can run 24/7

  • Improved worker safety by taking operators out of extremely heavy lifting situations

  • Improved quality variance of finished parts

  • Easy to operate user interface

Universal Robots - Collaborative Robot Solutions

Universal Robots is a result of many years of intensive research in robotics. The product portfolio includes the UR5 and UR10 models that handle payloads of up to 11.3 lbs. and 22.6 lbs. respectively. The six-axis robot arms weigh as little as 40 lbs. with reach capabilities of up to 51 inches. Repeatability of +/- .004" allows quick precision handling of even microscopically small parts. After initial risk assessment, the collaborative Universal Robots can operate alongside human operators without cumbersome and expensive safety guarding. This makes it simple and easy to move the light-weight robot around the production, addressing the needs of agile manufacturing even within small- and medium sized companies regarding automation as costly and complex. If the robots come into contact with an employee, the built-in force control limits the forces at contact, adhering to the current safety requirements on force and torque limitations. Intuitively programmed by non-technical users, the robot arms go from box to operation in less than an hour, and typically pay for themselves within 195 days. Since the first UR robot entered the market in 2009, the company has seen substantial growth with the robotic arms now being sold in more than 50 countries worldwide.
