HS-OSW

High Speed Orientation (Servo Motor) Spin Welder

The HS-OSW is a high speed pneumatic motion controlled orientation (servo motor) spin welder designed for smaller diameter, more difficult spin welding applications requiring delivery of high rotational speed while maintaining the highest degree of precision.

This servo drive spin welder is capable of orienting part halves relative to each other with a positioning accuracy of ± 1.0°. Exact start (home) and stop (final orientation) points can be programmed and precisely controlled.

When compared to non-orientation models, orientation (servo motor) systems typically:

  • permit precise orientation/alignment of part halves relative to one another.
  • allow precise depth welding (collapse distance or absolute distance) when orientation is not required.
  • enable welding of smaller parts with more difficult to weld materials.
  • are much easier to automate as the driver rotational position may be precisely programmed between welding cycles, allowing easier loading of the upper part half into the driver.

Standard Features

Ultra-Rigid Rectangular Column minimizes deflection of the system under even the highest pressures.

Servo-Electric Drive/Amp 0-7000 RPM Motor insures precise rotational positioning +/- 1.0 degree.

6" Color Touch-Screen User Interface with integral Programmable Operator Control Station simplifies parameter input and allows the following to be displayed: RPM, Weld Mode, Weld Distances (Collapse & Absolute), Hold Time, Pressures, Resettable Parts Counter, Total Machine Cycle Counter, Diagnostic Display, Micro-SD Memory Card Slot (Slot to support use of up to 2G Flash Memory Card), and Ethernet Connectivity.

Precision Linear Magnetic Stroke Encoder allows welding by Collapse and Absolute Distance and/or alarm monitoring these values.

Weld by Revolutions (orientation) or Time, Collapse Distance, Absolute Distance (non-orientation) allows the user enhanced control for applications requiring precision welding.

Time, Collapse Distance, and Absolute Distance Pass/Fail Windows allow the user to set min/max alarm limits for bad parts for quality control purposes.

Dual Speed Vertical Head Velocity and Position Control via Dual Proportional Valve for Pneumatic Pressure Control allows user to program individual settings for initial part contact pressure, weld pressure, and cooling pressure in passcode protected memory. Reduces cycle times and improves repeatability.

1.6" (40 mm) diameter 3.9" (100 mm) Stroke Pneumatic Cylinder allows sufficient force for virtually any spin welding application and permits parts loading/unloading with maximum clearance, as well as allowing welding deep within other components.

Spin Initiation (Trigger) by Height with Programmed Delay-Time simplifies setup. No limit switches to adjust when changing part height. Head-Down step used to "teach" system target part height. System retains learned height setting in programmed memory.

Sequence of Operation

  • 1.Operator loads part halves into holding fixture and driver.
  • 2.Operator initiates both cycle activation switches.
  • 3.Actuator moves driver & rotating part half (typically without rotation) into contact with the stationary fixtured part half.
  • 4.Operator is permitted to release cycle activation switches after part to part contact is made.
  • 5.Servo motor spins parts at user-programmed RPM for the number of user-programmed revolutions (or user-programmed: time, collapse distance or absolute distance) and terminates rotation when desired weld criteria is reached.
  • 6.Welded parts cool under pressure.
  • 7.Actuator retracts to home position and servo slowly rotates to user-programmed home position.
  • 8.Operator removes welded part from fixture.
