What Are Ball Plungers Ball Nose Spring plungers?

Spring Plungers Ball Plungers

Ball Plungers Spring Plungers operate in a similar manner to the pin counterpart, however, the ball movement allows for a heavier duty workload. For more specialist applications consider stainless steel spring plungers.

Ball spring plunger is a set screw of spring element comprised of a ball, a spring, and a shell.

Spring plungers are suitable for all cases where it is necessary to perform locking, positioning, or clamping by means of the use of spring pressure.

Similar names for ball spring plunger screws are positioning ball plungers, spring plungers, spring-loaded devices.

Ball spring plungers are a discrete mechanical devices to; secure, position, index, positively lock and apply lift-off pressure. They are a three-piece component; ball or pin as the contact point, spring of varying force, assembled into a small grub screw-like housing.

The housing is typically made from steel, stainless steel (A3 or A4), brass or plastic, with ball bearing steel ball or pinhead, are available in a range of threads, They also come as smooth body push-fit models for quick and easy installation.

The difference between a ball spring plunger and a smooth ball spring plunger.

The ball spring plunger is very similar in function to the smooth ball spring plunger, but the ball spring plunger is threaded, which is locked by the thread and uses a threaded drive to position and fine-tune another object. The smooth ball spring plunger touching the bead body has no thread and is used in close coordination with logistics.

Common specifications of the ball spring plungers are M3*8 M4*10 M5*12 M6*12 M8*16, etc.

Function

Ball spring plungers are often used in molds, fixtures, assembly, and other work. The movement of the ball is pushed by a spring with a certain pressure so that the lock piece can run smoothly. It is widely used in the foreign machinery industry.

They are suitable for an extensive array of applications across a wide range of different industries, e.g. for fixing, locking in place, positioning, and as a detent or for ejection.

In molds or mechanical equipment that need to be installed with springs, how to install a bare spring individually and accurately and conveniently is trouble for engineers, and the installation efficiency and results are often frustrating.

After the layout, the installation of springs and equipment is very difficult to control. The bare spring will fly randomly after being stressed. And some devices simply cannot complete operation with a bare spring. The ball screw can completely solve the above problems.

As a component that can provide pressure and accurate positioning, the ball spring plunger is mainly locked by a thread. There are two locking methods for the screw thread:

A slot and an inner hexagon, and the press-in type have two types of stainless steel and carbon steel housings. The screw body itself has long, short and standard types to suit the pressure and fix the body.

There are two types of springs light load and heavy load. The ball is made of hardened steel or stainless steel, and artificial materials such as nylon, polyacetal resin (polyacetal spring device), or phenolic resin can also be used. These materials provide high strength and durability with sufficient elasticity. The specific use depends on the requirements of the stressed material.

The spring plungers are used mostly as thrust pins or ejector pins. A spring plunger is used when an element in toolmaking or machine construction needs to be fixed, indexed, or positioned quickly.

Spring plungers in many different shapes and sizes can be found in the DGMF Mold Clamps Co., Ltd’s mold components range. The threaded versions are available with two different installation aids, either a slot for a screwdriver slotted spring plunger or a hex socket internal spring plunger for a hexagonal key.

The thrust element at the other end can be either a ball or pin. The spring plunger bodies are available in steel, stainless steel, brass, or plastic and can be threaded or smooth. The thrust balls and pins are available in steel, stainless steel, brass, etc.
