This article outlines the benefits for machine builders of specifying pneumatic cylinders with auto-cushioning.
In the industrial world, the primary goal is often to boost productivity while reducing costs. Pneumatic cylinders, in particular, are durable enough to withstand harsh environments, yet they also provide high performance at a competitive cost. However, actuators often need to operate as fast as possible and this must be achieved without introducing excessive shock or vibration to products and equipment.
Due to operating at a higher speed and with potentially increased loads, cylinders are often specified with an air cushion to prevent teh cylinder from self-destructing. The issue is that the manual adjustment of these end-position cushions requires time.
Experienced maintenance technicians are required to adjust the air-cushion valves, depending on the cylinders' operating pressure, speed and load. Once these parameters are changed, the air cushions then need to be reset for each job in order for the machine to run efficiently.
Manually adjusting the air cushion is not only time-consuming but it can put pressure on the technicians to complete the task as quickly and efficiently as possible, as well as incurring unnecessary production costs.
With the introduction of a new type of air cushion that automatically adapts to changing conditions, the headache of manual adjustments is eliminated and productivity is increased, ultimately reducing maintenance costs.
Camozzi Automation's Series 23 pneumatic cylinders embrace the innovation of auto-cushioning. The auto-cushioning system works the same as many conventional cushions, except that instead of a needle valve, the air is exhausted with the use of shaped sleeves that have a number of holes accurately positioned with precisely set dimensions. As the system cleverly adapts to various combinations of speed and applied mass, the self-adjusting cushion is a fit-and-forget feature.
Eliminating the need to regulate settings, the Series 23 pneumatic cylinders are tamperproof, offering a long, maintenance-free service life.
While the cylinder benefits from smooth, jolt-free movement, the reduction in vibrations and noise is also noticeable. Despite appearing less intrusive, the cushions guarantee higher reliability and constant performance over time.
If the parameters such as friction and pressure change, the self-adjusting cushions ensure proper deceleration every time. Reducing the acceleration forces acting on components and workpieces, the wear and tear is reduced and vibration is minimised.
Series 23 cylinders are suitable for use in many industrial applications, especially if working conditions vary. Reducing the installation and commissioning times, the auto-cushioning provides a cost-effective alternative to manually adjustable cylinders.
