Brake Press – Dener Eco-Friendly Electric Servo 5020

As part of our planned growth strategy, Plymouth Industries, Inc has added the Dener Servo CNC Press Brake to our machine shop.  This next-generation non-hydraulic advanced bending machine combines eco-friendly power consumption with faster productivity, increased accuracy, greater flexibility, and consistent reliability. 

The Servo bending machine has a closed O-frame system that supplies a rigid frame with no deformation under large forces. The result is better tool alignment and more accurate bends.  Dener Electric Brake Press comes with an advanced CNC controller, fast and accurate punch and die clamping, and a multi-axis back gauge system.

Press Brake Operators easily make perfect sheet metal parts at a very low cost.  Dener utilizes stringent manufacturing technologies during production to manufacture the highest quality machines. Standard Dener electric presses comes with a 3D graphical CNC controller offering simple operation, quick and easy 3D or numerical part programming easy set up of the machine, and auto calculation of the bend sequence. Optional 3D offline programming features the ability to create programs on an office PC then transfer them to the CNC control by LAN or USB.

Key Features:

• Eco-friendly green manufacturing with up to a 50% energy savings
• Up to 30% faster productivity
• Capability for advanced bending
• Works quietly, having no noise, and providing silent working conditions
• Extremely fast press brake tooling changes
• Maximum control of vertical tolerances during the bending process
• Extremely accurate clamping, positioning, and alignment
• Individual clamping pins for each tool segment for superior clamping force
• Vertical and horizontal tool loading and unloading for maximum speed and safety
• Professional finish, including a slide rule for ease of tool positioning

How Servo Electric Bending Presses Work

Servo Brake pressing force by means of synchronized two servo motors that transfer the power with the help of special belts and pulleys. During the upper beam down movement, the servo motors place a tension force F on the belt that is multiplied equally in every belt segment. The force of each motor creates a downforce many times greater. The ram return force is derived from mechanical springs located at the side of the machine. These springs are compressed during the pressing time, but recoil after completion of the bend pushing the ram to a programmed top of stroke position.
