Gas springs in vacuum veneer press ensure easy handling and protect the valuable machine
The flaps of the veneer press place high demands on the gas springs
A vacuum veneering press is a ground-breaking invention, in particular for small carpenter’s shop. It is a fully-fledged substitute for a hydraulic veneering press – with an enormous advantage: It doesn’t require the time-consuming and relatively cost-intensive heating of the hydraulic veneering press. The vacuum veneering press is immediately ready for use.
The vacuum veneering press has two flaps: The upper flap is just for protecting the vacuum membrane of the flap below when the press is not needed.
Requirements for the calculation of the gas springs
- Firstly, each gas spring is configured for its respective flap. However, when both flaps are lifted together, the gas springs work as a team, i.e. lifting both flaps is just as easy as lifting just one – although, in this case, the pivot point of the upper flap changes!
- It has to be made sure that the flaps never fall down without control, even on the last 10 – 20°. This could damage the vacuum membrane and result in a very expensive repair.
The gas springs in a double pack ensure a smooth workflow when operating the machine
When the flaps are closed, the gas springs are neutral, i.e. the flaps are kept in this position by their own weight. To open the flaps, you lift them a little bit by hand. After a few degrees the gas springs take over, and open the respective flap until the desired opening degree of about 50°.
When working, the gas springs keep the upper protection flap safely open. The lower flap with the vacuum membrane lies over the work piece which has to be veneered. Once the process is finished, the mechanical locks are released. However, the membrane flap opens only when this is actually required, i.e. when lifted slightly with the hand. The gas springs do the rest!
If the machine is no longer needed, it can be folded up to save space and be pushed in a corner. Also in this case the gas springs ensure that the flaps stay firm in their position and don’t move.
If the vacuum veneering press is closed, the gas springs behave neutrally. They exert no force on the flaps.
The protective cover is folded up and safely kept open by the gas springs.
The gas springs can also easily deal with both flaps open at the same time.
When the vacuum veneering press is not needed, it can be folded up to save space.
Products used
Push-type gas springs
The application possibilities of DICTATOR gas springs are as varied as our model variants. That is why DICTATOR does not have fixed type tables and only a few stock types. We manufacture our gas spring for your application according to your wishes – from a single unit to large quantities. In addition to high quality, DICTATOR gas springs also offer numerous possible additional features such as a valve, oil chamber, protective tube, compression spring or bio-oil, which considerably extends the range of possible applications.
