This document is intended for existing users and owners of Stuga Flowlines to help explain the improvements and enhancements made to the flowline / ZX3 / ZX4 range of machines into out latest flagship product - the ZX5
A video of the machine in production can be seen here https://vimeo.com/279288374
Mechanical Enhancements
Twin V Notch Heads
Four dedicated, direct drive motors are used to power 4 V notch blades. The arrangement allows a front or rear V notch to be cut in one pass, as opposed to two passes (as on older Stuga machines). This reduces the cycle time of all V notch operations. Y notches are now carried out on the saw side of the machine (see Y Drive)
Tru-loc Gripper System
A dual-tooth fixed gripper design accurately and reliably locates into the profile
- Tapered pins on both sides of machine ensure an accurate and reliable datum
- 2 holes and pins are used to cover all profile types - this eliminates the need for a "G" axis sideways movement on the gripper
- Elininates gripper slip
- Allows a more dynamic acceleration and deceleration on all x axis movements, therefore improving cycle time
Roller beds
- All profile slideways on both sides of machine consist of roller beds
- Simple and inexpensive to replace if worn
- Profile slides with negligible friction
- No marking of profile on base
- Rollers lift and place profile onto transfer conveyors, reducing both profile marking and possibility of profile "tipping"
- Allows a more dynamic acceleration and deceleration on all x axis movements, therefore improving cycle time
Y Drive for Y notching
Y notching on Stuga flowline has always been a particularly difficult operation to maintain a necessary high accuracy due to many factors,. often outside of the machine's control
- Profile Extrusion Tolerances in profile width
- Profile length expansion in the time between machining and sawing (a 6 metre length expands by 1.2mm with just a 2 degree temperature rise)
- Linearity and accuracy of one side to the other
- Operator care and attention to detail
- Wear / backlash on linear axes
The Y drive system overcomes these issues by producing the entire Y cut in one operation in a similar way to an arrowhead.
- The saw centralising feature, widely recognised as a ideal way to overcome profile width tolerances when cutting arrow heads, now has an "offsetting" axis.
- This allows the saw to cut a square then mitre and vary the position of this to create Y notches of various depths
- Because this is done in one operation, there is no opportunity for a "line up" error between the machining side and the sawing side
- The toothed gripper is very important because allows the bar to be pulled back out of the way when creating the Y notch. This prevents the opposite prep getting created on the following piece on the bar
- The centralising feature means that any profile width inaccuracies are eliminated
