INNOVATIVE USER INTERFACE

An innovative user interface provides graphic tool images to aid with selections, making entering tool information easier than ever before. Operators interact with a single graphic screen. No tool measurements or electronic adjustments are necessary for routine tooling applications. The operator simply selects the tool to be used – punching, forming, wheel tool, scribing, marking or tapping – and the control software automatically determines the correct stroke settings. No further input is required.

LVD’s hydraulic ram also offers the flexibility of electronic adjustments and features that take advantage of the intuitive control interaction. Users can apply custom settings or alterations to stroke elements such as depth offset, dwell and ram speed, to further maximize machine capabilities.

Patented Smart Stroke® programming maximizes productivity by automatically calculating the optimum hover height for every stroke of the ram.

Strippit-M-2014-5

PROGRAMMABLE RAM MODES INCLUDE:

Standard Smart Stroke – The tool is kept close to the material on short table moves. As hits move farther apart, the software automatically increases the ram hover height to provide clearance for sheet warpage.

The Smart Stroke system also allows the machine to run mechanical machine programs with no need to edit traditional nibble routines or input hover height commands.

Forming – A dwell can be programmed at the bottom of the stroke, allowing the material to flow more completely into the desired shape, minimizing springback and improving the quality of the formed part.

Quiet Punch – The tool is programmed to rapidly approach the material, then slow to enter the material, continuing until shearing is complete. Once breakthrough occurs, the ram completes its cycle at rapid speed. This process reduces noise and shock while maintaining productivity

Strippit M-Series punch presses feature a large 47-station turret configuration that offers tremendous flexibility and capacity. This versatile turret design allows every station to accept shaped punches and dies, reducing setup time.

The Strippit M-Series turret is gear-driven from the outer diameter for smooth, precise motion. Shot pin assemblies are also mounted beyond the punch and die locations to optimize alignment at the tool during the punch cycle.

Self-stripping tooling uses the punch guide to firmly press the material down on the die. The guide continues to hold the sheet against the die until the punch has retracted into the guide, preventing distortion of even the thinnest materials. The end result is flat parts with virtually burrfree holes, greater finished part accuracy and increased machine productivity.

Turret capacity can be easily expanded through the use of indexable Multi-Tools

Large tool change door allows easy access to the turret for quick tool loading. Quick change die holders further reduce turret set-up time.

Ability to punch at any location on the sheet using any turret station within the nominal sheet size reduces repositioning and maximizes productivity.

Joystick mounted near the tool load door provides easy, convenient rotation of the turret for tool changing

THREE STANDARD AUTO-INDEX STATIONS

Strippit M-Series punch presses are equipped with three “D” size geardriven auto-index stations that are a full 88,9 mm. These programmable stations make it possible to punch shapes at any angle to increase flexibility and improve finished part quality.

Large auto-index stations accept a variety of indexable Multi-Tools, further enhancing turret capacity and flexibility while reducing setup time.

ENHANCED FORMING CAPABILITIES

Strippit M-Series machines provide expanded forming capability with a full 25 mm feed clearance between the upper and lower turret. This generous feed clearance allows for the production of higher forms such as lances, louvers, embossments or card-guides.
