Expandable insert for belling plastic tubes 1

This is a suggestion for the expandable insert used in belling machine:
• Video
to create an annular groove on heat-softened end of a tube.
The insert ring consists of orange and blue inserts.
Each insert belongs to a parallelogram mechanism, the base of which (yellow or green sliders) can move axially. Springs that tend to turn violet bars forwards are not shown.
When the sliders move backwards, the inserts move inwards under the spring action.
When the sliders move forwards, the front violet bars collide with the front disk (in white) and move the inserts outwards, to set the inserts into a complete ring.
To hide the insert ring, the yellow slider moves backwards before the green one.
To expand the insert ring, the green slider moves forwards before the yellow one.
There are many ways to control these motions by only one actuator. A possible way is the mechanism shown at
• Teeth-uncompleted gear...

Hello Mr. Thang! Do you make tutorials for the Autodesk Inventor? We could learn a lot from you!

[@thang010146]

No, I can't because it would take a lot of time.
Please use tutorials of the software shown in its Help topic.

[@GamerX-ox6mh]
