What Is a Plunger?
A plunger is a mechanical component that has a spring, a retainer, and a ball or pin at its tip. When a load is applied to the tip, it sinks into the body, and when it is released, it returns with the force of the spring.
Plungers are machine element parts that fix and position workpieces by sliding and swiveling. They can be easily incorporated into equipment and devices without having to design and manufacture pins, springs, and hold downs by themselves.
The types of plungers are described below.
- Ball Plungers: The ball-shaped tip of the plunger makes it easy to slide and position.
- Pin Plunger: The pin-shaped tip of the pin plunger allows for adjustment of the position and a longer stroke than the ball plunger.
- Indexing Plungers: The pin tip enters a pre-set hole or groove and is positioned by the action of a built-in spring, and the positioning is released by the operation of a knob or other device.
Uses of Plungers
Plungers are used in a wide variety of applications, including positioning of equipment and devices, workpiece extrusions, jigs for positioning drill holes, and lever positioning. They are used in food, packaging, printing, and hand-song making machines.
Below are some examples of use for each plunger.
- Ball Plungers: Positioning levers, knobs, pillar stoppers
- Pin Plungers: Thrusting press work, stoppers for eccentric circular levers, positioning of changeover jigs
- Index Plunger: Positioning when attaching/detaching parts, fixing nozzle attachment/detachment position, positioning of cutter
Principle of Plungers
-
Ball Plunger: Useful for positioning of slide mechanism. When a load is applied, the ball at the tip sinks into the body, and the plunger load at the notch is released to allow the ball to return to its original position by spring force.
-
Pin Plunger: Useful for pushing out a workpiece. When a load is applied to the pin at the tip, the pin sinks into the body and returns to its original position when the load is released.
-
Indexing Plungers: Used for positioning, the pin retracts or pops out when the knob is operated.
There are two types: return type and rest position type. The former requires constant pulling of the knob to retract the pin, while the latter allows the pin to be held even when released from the knob.
The shape of the tip can be tapered or spherical. In the former case, a hole is drilled in the mating part, but rattling occurs depending on the amount of clearance between the hole and the pin, while in the latter, the mating part is V-grooved and no rattling occurs.
The pressure indication of the plunger uses load and newtons, where the minimum pressure is the force required for the plunger tip to start sinking and the maximum pressure is the pressure at the point where the plunger has sunk fully into the body.
It is important to select the appropriate shape for the application and to check the load and size.
