Keeping in mind today’s evolving market and the ever-changing needs of demanding customers, businesses have to constantly be on their toes to offer the best. One way of meeting timely deliveries and also quality standards is by using the right tools.
Take the pulse tool, for example. An upgrade from the impact wrench, this tool offers you all the benefits of an impact wrench, along with a host of other features like better operations, greater operator comfort and more durability.
Our Accura range of oil pulse tools offers you a host of features that can benefit your operations, and you’re bound to find one that suits your needs. However, before we talk about how to select the right pulse tool, let’s spend a few moments understanding pulse tools, and how they work. While a pulse tool performs the same task as an impact wrench, its operations are quite different.
The hammer mechanism of the impact wrench is replaced by the oil pulse unit. The oil pulse tool has no ‘metal to metal’ contact, which provides a softer and stable ‘impulsing’. The result is less vibration, lower noise levels and longer service life when compared with conventional impact wrenches. In pulse tools the maximum installed torque is controlled by regulating the maximum hydraulic pressure in the pulse unit. For this purpose, the tool comes with an easily adjustable by-pass valve that controls the flow of oil in the impulse unit (from high pressure to low pressure), and thereby limits the power of each pulse.
Choosing the right pulse tool
What are the parameters that you need to keep in mind while selecting the right pulse tool for an application? Productivity and quality of an assembly operation are critical areas to consider, and for that, you have pulse tools with amazing features, such as high run-down speed, higher power-to-weight ratio or even no reaction force. But how do you know that’s what your application needs?
Here are a few questions to ask yourself before considering pulse tools for an application:
Is the joint soft or hard?
Joints are classified based on where they stand on a scale from hard to soft.
A hard joint has very little rotation at the point of contact, less than 30 degrees. An incorrect tool can cause more damage due to torque scatter if the shut-off does not happen immediately. A soft joint has a greater margin for rotation and may require more pulsed to reach the accuracy target. There is definitely less torque scatter, but the machine can suffer wear and tear due to more use. Additionally, in some cases, the bolt may need to be rotated more than 360 degrees to get tight, requiring more pulses.
