Description

Rapid-Clamping System Flexline I 4.0 with Condition Monitoring

Continuous monitoring of die clamping

Advantages
● Continuous condition monitoring – detection of stripping forces in the die
● Tool breakage and wear detection
● Avoidance of downtimes
● Maintenance detection – fast troubleshooting
● Remote maintenance option
● Process stability

Measured data and evaluated information
• Clamping force in real time
• Overload of the clamping element
• Unusual stripping forces
• Process forces at the clamping point or die
• Error analysis by recording the clamping force curve
• Protocol for the service case

Application
In automated die clamping systems for continuous monitoring of the clamping point or the manufacturing process.

Description
The rapid-clamping system Flexline I 4.0 is equipped with sensors that continuously measure the clamping force and clamping pressure of the used clamping element in real time.
Thus the condition of the die clamping is recorded and monitored. Unusual stripping forces in the die or an overload at the clamping point can be detected and suitable measures can be taken immediately.
The measured data can be transferred to the press control and evaluated via a data interface, e.g. IO-Link.
As an alternative, a control with evaluation software can also be supplied, which graphically displays the status of the die clamping in a forcetime diagram.
A further sensor enables conclusions to be drawn about the degree of contamination of the pressure medium, from which maintenance measures can be determined to prevent the clamping element from failing.

Rapid-Clamping System Flexline I 4.0 with Condition Monitoring

Flexline Rapid Clamping System with Push Chain 3.2280

A pusher chain driven with an electric motor moves the rapid clamping system with it's attached clamping cylinder automatically to the clamping edge of the die.
The T-slot in the machine provides guidance for the pusher chain and the clamping element.Clamping and unclamping of the cylinder is made by applying pressure to the cylinder, depending on the design. During unclamping, the clamping element moves automatically from the clamping position to the parking position.

Application
Rapid clamping systems are used for the automatic clamping of dies of varying sizes on the press ram.

 

Advantages

  • 8 different clamping elements
  • 4 different T-slots
  • 3 different adjustment tracks
  • electrical or pneumatic drive motor
  • easy to service, easily exchangeable modular assemblies ensure high availability of parts
  • technical design and finished drawing in just a few minutes
  • highly flexible, low-maintenance hydraulic hoses with high burst pressure

 

Versions
Flexline rapid clamping systems can be supplied in the following variants:

 

  • clamping elements Hollow piston cylinders, clamping cylinders with locking mechanism, spring clamping cylinders or sliding clamps
  • T-slots 28, 32 or 36 mm or 1 1/16"
  • cdjustment tracks (tracks of the clamping element) 660, 820 or 1100 mm
  • drive motor electrical or pneumatic
  • optional position monitoring (adjustable) micro switch for “end position” and “intermediate position”
  • position monitoring of the “die position” attached on the left or right hand side
  • chain case in galvanised design or painted individually at customer’s request
  • option: Design with UL-compliant components
  • various Harting connectors to choose from for motor current and monitoring signals
  • option: Socket housing for assembly to machine
Flexline Rapid Clamping System with Push Chain

Rapid clamping system with pneumatic cylinder 3.2295

The electrically or pneumatically driven push chain moves the clamping element attached to the rapid clamping system automatically from the parking position to the clamping position at the clamping edge and then back to the parking position.
The T-slot of the machine serves as the guide for the push chain and clamping element. The push chain also serves as the energy chain for accommodating the hydraulic and electric lines of the clamping element.

Applications

  • automatic clamping of dies on press rams
  • for dies varying in width


Versions

  • Hollow-piston cylinders, double acting, max. clamping force 115 kN
  • Hollow-piston cylinders, single acting, max. clamping force 104 kN

  • Spring clamping cylinder, single acting, max. clamping force 100 kN
  • Sliding clamp, single acting, max. clamping force 78 kN
  • Angular clamp, single acting, max. clamping force 66 kN


Special features

  • cost-effective, robust solution for short distances of travel
  • easy installation using standard clamping elements
  • for fixing, no modification to the press ram is required
  • rapid adaptation to various die sizes
