FINN POWER EB 

BENDING SOLUTIONS FOR AUTOMATED BENDING FINN-POWER EB Automated Bending Cell adds to the productivity of your sheet metal working process.

In many cases the press brake, the standard technical solution for the bending of sheet metal components, is not only the typical but also the most conventional manufacturing method. Yet, there are many manufacturing situations where an automated bending cell offers benefits far superior in terms of total manufacturing cost component quality automation level. FINN-POWER's new EB bending cell is your optimal solution for bending large components from thin sheets in long series automatically. With FINN-POWER EB the machine operation cycle is fully automatic and includes the following stages: loading, rotation during the bending sequence, bending, and unloading. Operation The machine is operated by a CNC and a PLC (Programmable Logic Controller). The CNC and the PLC exchange information and synchronism through digital profibus. The machine's main functions as well as all the axes involved in the bending are controlled by the CNC. An onboard PC and a color display are included in the standard configuration of the machine to create an ergonomic machine interface. Bending generally starts from the outside edge of the sheet and continues towards the inside of the sheet, working one side after another in sequence. The sheet is loaded automatically onto the working table by a robot where a manipulator pushes it against the positioning manipulator holds the workpiece firmly during all the manipulation phases.

The bending tool holds the required portion of sheet in position during the bending action. Two blades manipulate the portion protruding from between the counterblade and the upper tool, upwards or downwards according to the nature of the bend (positive or negative) and the required angle, CNC programmable. The ready-bent component is automatically exited, and the next flat workpiece loaded.

BendTerm software for machine programming BendTerm is a Windows-based application which is run on the onboard PC, connected to the numerical control.

INGENIOUS BASIC PRINCIPLE

ROBUST, CAREFULLY ENGINEERED CONSTRUCTION The bending principle of the FINN-POWER EB bending cell is simple and based on the following main components: Two frames: the stationary main frame of the machine and a C-frame with hydraulically actuated swinging movement upwards or downwards. An upper tool with hydraulically actuated vertical movement CNC controlled parameter H1 and a fixed lower tool for holding the workpiece in position during bending. Upper tool segments, which determine bend length. Upper 6 and lower blades, which transfer the bending force onto the sheet.

Key components in the material management of the cell are the very fast suction cup robot which loads the flat component, and the manipulator, which places it against numerically controlled positioning pins, rotates the workpiece and, once all sides have been bent, transfers it onto the unloading conveyor. Thus the entire bending process can be automated, and the bending of components automatically continues as long as programmed.

Axis interpolation A fundamental characteristic of the EB bending technology is the movement of the blade. The contact line of the blade and the material being bent remains constant. This is achieved by numerically controlled interpolation of the two axes that operate blade movement.

This solution eliminates scratching of the material; thus even sensitive materials can be bent while high surface quality is retained.

A RANGE OF OPTIONAL EQUIPMENT AND FEATURES TO MEET YOUR SPECIFIC MANUFACTURING REQUIREMENTS Additional short blades ASP The additional short blade construction consists of two numerically controlled carriages installed within the C frame structure. Short blades standard manufactured for each carriage, can reach up to with alternative are mounted onto the carriages and the bending of small wings. The option can be automatically activated and deactivated during the bending cycle. The bending can be performed either upward or downward, therefore positive and negative bending can be achieved even with the ASP. Integrated engraving unit EU The integrated engraving unit is a forming tool mounted on one of the carriages of the ASP. It is used for making a groove in the sheet to facilitate subsequent bending. Hydraulic bending die HBD Hydraulic dies can be mounted onto the ASP carriage for bending components the sides of which are not parallel or for bending portions of the sheet that would not be reached in other ways. The option is always a custom-made solution. A RANGE OF OPTIONAL EQUIPMENT AND FEATURES TO MEET YOUR SPECIFIC MANUFACTURING REQUIREMENTS Automatic tool change ATC Automatic Tool Change can be chosen in order to decrease the number of tools required and to shorten set-up times. With it, the length of the upper tool can be automatically adjusted. The system consists of two side transfer units each supporting a set of narrow tool segments. The tools dimension adjustment is first made by side transfer units, which load or unload from the central part of the upper tool the narrow segment and afterwards move the end tool segment to the further position. Additional upper tool AUT The AUT mechanism allows the changes of upper tool mechanism by lowering an additional tool below the standard upper tool segments. It is often required for making bends that are hidden, i.e. when the bending point to reach is shadowed by the previously bent profile, and negative. Further, the possibility of using special tools provides additional versatility, like big radius bend, tube profiles, wide inward bending, and holding of the sheet while pressing with the blades. Reversed bending sequence CLL sequence can be reversed with the CLL option, which forms two gaps in the upper tool, either in the standard bending cycle short sides are symmetrical or asymmetrical to accommodate bent first and long ones afterwards. This sequence helps in bending the edges of the longer sides. Hydraulic tool clamping HTC Control cabin cooler Changing upper tool dimensions is facilitated Acceptable ambient and made faster by the hydraulic tool clamping temperature for the option. In order to change the upper tool dimension standard bending cell the operator simply needs to unlock. For hydraulic clamp and press a clip to be able to operation in warmer move the segment into the desired position. temperatures, a control cabinet cooler is required. BendCam FP Profiler software BendCam is a graphic programming system for FP Profiler is a Windows-based application, automatic bending technology. The program can which is run in a PC connected to the numerical be used for designing and programming a large control via serial connection. The bending program is quickly generated by using a library of variety of components. Component geometry program is quickly generated by using a library of data can also be given in many commonly used available profiles as support, or simply by realizing formats. dxf, .iges, .dwg, or .mi.

Machine program is made mainly by using a mouse to point the location of positioning pins FP Profiler can be installed on the machine PC, as and the bending sequence of edges. The program an off-line programming station. The FP Profiler, can be simulated step by step in order to check which is an easy operator-machine interface, generates readable and modifiable programs with whether the tooling profile is compatible with the workpiece. After testing the program is the BendTerm to be used in the CNC of the EB. converted into a machine program by using material factors. MATERIAL MANAGEMENT OPTIONS Flexible, modular solutions for automated material management are a traditional FINN-POWER unmanned operation for added productivity and strength. The EB bending cell can be upgraded by eliminating tedious work stages. SGR NTR FINN-POWER's SGR stacking robot provides the material management link from a punching/shearing cell, from a laser cutting machine cell or from the NTW storage. Its primary function is to load components either direct or with a buffering function. It can also stack components on a separate pallet and load the bending cell from a pallet brought from NTW or from outside the system. Negative last bend LBN If the last bend made is negative i.e. downwards, the standard unloading conveyor placed in the middle of the machine cannot be used. With the LBN option, such components are unloaded by a carriage that pushes them laterally out, without taking the part to the center of the machine table. Unloading and stacking system USS The innovative idea of the USS option is to use the loading device for both loading the blank sheet and stacking the bent parts. The USS loader picks up the components either from the standard loading table or from the NTR or SGR centring table and takes them to the machine for the bending. Meanwhile, the previously bent part is unloaded and centred on the TUT table. The loader picks up the part from the TUT table and stacks it as desired. The stacking area available is four EUR pallets. There are several stacking addresses that can be combined to optimize area and product storage.

Nonmagnetic material separation NMS With plastic coated sheets and under conditions where static electricity may be a problem, the NMS option eliminates it. The suction cup rows closest to the edges of the sheet operate at first to lift the edges for better sheet separation. Blowing compressed air between the sheets and additional steel brushes finally contribute to the separation. The option is for stand-alone machines only.
