Basic Functions of a Spring Making Machine

28th April 2021

This article refers to the mechanics and operation of a  small-scale spring rolling machine. The project scope includes the application of this spring-making machine in the small-scale industry. It can produce open and closed helical springs having different spring and spring coil diameters. One can make use of this machine to manufacture springs on a small scale without much expenditure.

Why a Handheld Machine?

In the first instance, the procedure for making springs is the same whether fully automated, or partly manual in process. The advantage of seeing a manual machine is that it is possible to see much more of the process, and therefore to understand both he processes, and the various stages material will go through as it is formed into a spring.

Therefore, the aim would be to learn about several types of springs used in different automotive parts and similar mechanisms. It also throws light on the crucial role played by these springs in different kinds of instruments.

The example suggests that you  have prepared the spring-making machine with a very simple arrangement. You can operate this machine manually to produce closed coil helical springs of different lengths and diameters.

This project explains how a spring rolling machine works. Please note that the term rolling refers to a process whereby the operator bends a metal wire in a curved form to create different springs.

Spring Machine Arrangement and Process of Spring Making (Hand Operated Machine)

Here is a simplified explanation of the machine layout and how the machine works.

When you rotate the handwheel, it makes the shaft run—an MS plate layout couples the primary shaft with the bearing. The handwheel rotation makes the main shaft rotate. Before turning the handwheel, you have to lock the wire with the locking nut of the spring mandrel.

A guide affixed to the machine-frame stand of the spring-making machine applies the load to supply the said wire. The guide can rotate freely as per the shaft speed.

One end of the primary shaft is joined to that chuck. Similarly, the other end of the same is connected to the handwheel. A mandrel with several diameters (or a spindle shaft) is joined to that chuck, and then it starts to rotate.

When you turn the handwheel, it turns the rolling shaft. The same part makes the spring roll. The operator can decide the changes in the spring length based on the spring rotation. Once the operator has completed the aimed spring length, he can stop the handwheel rotation.

The operator keeps on rolling the spring wire until the desired length is achieved. It marks the end of the production of the final product of spring. You can repeat the entire procedure for mass production.
