DLVW-2472

Digital (Servo-Drive) Linear Vibration Welder

The DLVW-2472 is a hydraulic motion controlled digital (servo-electric) drive linear vibration welder capable of welding parts up to 24" x 72" (610mm x 1829mm) or multiple smaller parts.

The patented 2-pole digital (servo) drive technology allows vastly improved process control while substantially increasing the available power. This technology offers improvements in overall efficiency (significant power increase), capability (amplitude/process control), and productivity (application benefits) beyond any vibration welding design currently on the market.

Standard Features

Patented High Output 2-Pole Digital (Servo) Electromagnetic Drive System allows higher efficiency and a significant increase in weldable area over industry standard 3-Pole systems. Can drive larger/heavier tools with a lower power demand.

Up to 70 sq in (452 sq cm) Weldable Surface Area (Polypropylene) the most powerful welder in its class.

0-260 lb (0-118kg) Upper Tool Weight capability makes this welder able to drive the heaviest production tools.

Patented Position-Based Amplitude Control Network allows ramp up to full amplitude in as little as 0.04 seconds. Amplitude adjustment from 0.040 - 0.070in (1.02 - 1.78mm) peak-to-peak in increments of 0.001in. X-Axis and Y-Axis (vibration direction and perpendicular to vibration direction) repeatability of < +/-0.001in.

Continuous Tuning by Closed-Loop Digital Control eliminates the need for a separate auto-tuning step during setup and assures that the machine operates at peak performance throughout the weld cycle.

Precision Digital Distance Measurement System allows welding by Time, Collapse Distance, or Absolute Distance with a repeatability of +/-0.001in (+/-0.025mm) and/or alarm monitoring these values. A High-Resolution Encoder integrated into the welder Lift Table monitors processing dimension values.

Allen Bradley CompactLogix PLC with PanelView Plus 7 - 700 Color 6.5in Touch-Screen Graphical Display simplifies parameter input and allows the following to be displayed:

  • Weld Program/Setup #
  • Frequency
  • Amplitude
  • Contact Time and Force
  • Weld Steps 1 through 8 (Time, Amplitude, Force)
  • Cooling Time and Force
  • Ethernet Connectivity

25 Weld Program/Setup Memory allows storage for instant recall, minimizing tool change time.

Process Verification Windows (pass/fail) compare and alarm the user when actual parameters are outside customer programmed minimums & maximums.

Multi-Level Passcode Protection limits parameter adjustment to qualified personnel only.

External 120VAC Duplex Electrical Outlet allows user to easily connect small auxiliary equipment such as computers, printers, radios, etc.

Enhanced Sound Enclosure for maximum noise reduction (<80 dBA). Enclosure is completely de-coupled from the equipment frame to isolate noise from the swing frame.

Zero-Force Opti-Touch Cycle Start Switches minimize operator fatigue.

Two Valve Lower Tooling Actuation Pneumatic Valve Pack allows user to program additional pneumatic motion on lower tooling such as part clamping or part eject.

Sequence of Operation

  • 1.Operator loads part halves into holding fixture(s).
  • 2.Operator initiates cycle activation switches.
  • 3.Safety door closes.
  • 4.Lift table rises, applying pressure between the two part halves.
  • 5.Vibration begins, melting the joint area between the two halves.
  • 6.Vibration stops when user programmed target Time (or optional Collapse Distance or Absolute Distance) is reached.
  • 7.Parts are held together under pressure to allow them to re-solidify.
  • 8.Lift table lowers, carrying part(s) in lower fixture(s).
  • 9.Safety door opens.
  • 10.Operator unloads part(s) from lower fixture(s).
