Information about Tungsten Ball Pen

In our production live, a ballpoint pen for us is very common and widely used, but how much do you know about the tungsten ball pen? Let's take a look at it.

The following is a list of contents:

l The principle of the tungsten ball pen

l The production of tungsten ball pen ball beads

l Note on the use of a tungsten ball pen

The principle of the tungsten ball pen

The writing principle of the tungsten ball pen is to use the tungsten sphere to make direct contact with the paper surface when writing, and then generate friction, so that the tungsten ball rolls in the ball seat and brings out the ink or ink inside the refill to achieve the purpose of writing. The nib of a tungsten ball pen is a small tungsten alloy ball, and the small tungsten sphere is embedded in a small cylindrical type copper bowl, and then connected to a plastic tube with ink, and the ink will flow down from all around with the rotation of the tungsten ball.

The main structure of the tungsten ball pen structure principle is the incomplete engagement of the upper and lower tooth column, when the lower tooth column in the upper tooth column pushes down out of the guide groove, due to the role of the spring, the teeth of the lower tooth column will slide along the bevel of the teeth of the upper tooth column that are engaged, will turn an angle and slide to the other side, it will be pressed down, so repeat it can realize the function of the tungsten ball pen.

The production of tungsten ball pen ball beads

The ball of a tungsten ball pen is first made into small particles slightly larger than the standard size and spread on a board with grooves, and these small particles are made to enter the round grooves with only the top exposed. Then a heavy and flat top plate is placed on top of these small particles, and grinding oil is injected between the two plates so that these small particles are immersed in a lubricating mixture containing powdered diamond.

Then turn the lower plate, so that these small particles of tungsten alloy ball in the round groove constantly tumbling and rolling, in the groove wall, the top plate and each other are constantly in contact, diamond powder constantly to these small particles of the edge grinding off, so that they gradually become round and light. The grinding process also has to stop several times, this small tungsten sphere will be taken out and washed, for testing, until the production of the smoothness of moderate, meets the standard of the small round ball.

Note on the use of a tungsten ball pen

When using a tungsten ball pen, do not write on paper with oil and wax, or oil and wax embedded in the copper bowl along the edge of the tungsten bead affects the ink and can not write, but also to avoid the impact of the pen, exposure to the sun, when not in use with a good set of a pen cap, to prevent touching the nib, pen rod deformation and oil leakage from the refill and contamination of objects.

tungsten ball pen writing, angle control at 55 ° to 70 ° is the most ideal, at this time, only tungsten alloy ball contact with paper (tungsten alloy ball is not only very hard, but also not easy to wear, is the ideal ball pen ball), the mouth does not contact the writer, to ensure that the tungsten ballpoint pen in good writing condition to extend the service life.
