A spring making machine, also known as a spring coiling machine, or a coiling machine, is a device that is used to make springs in the applications of the industrial fields, such as cars, motorcycles, 3C consumables.
Springs are made of steel and presented as helical or spiral wires, and they can be small, medium, or heavy depending on the width of the wires and the sizes of the springs.
There are mainly four types of springs that can be seen on the market, including compression springs, extension springs, torsion springs, and constant force springs. The former two types are designed as two opposite concepts, one is for being compressed between two surfaces, and the other is for widening the two surfaces.
The torsion springs are used neither for compression nor for extension, they store the potential energy of the two surfaces by being held by the hook on each end and twisted. The constant springs are attached to the drum on one end, and the other end is free and would be attached to the loading force, such as in the seatbelts.
These spiral and helical instruments are all made by the spring making machines, which can be operated either manually or automatically, in combination with the components that made up the entire device, in order to make the versatilely used springs.
A spring making machine is usually mounted on the chuck with multiple jaws. In the middle of the jaws, there is a rod that is so-called an arbor, which is used for being the X-axis to move forward and backward horizontally.
On the base of the chuck, which is around the middle arbor, there are cut slide and wedge pitch slide that are installed on a center base for the Y-axis operation, which works vertically.
On the spring making machine, the working wires would be set on the arbor, and with the moving forward and backward of the arbor, the wires would be coiled to form the shape of the springs.
The wedge pitch slide helps the arbor to stay in a particular position when the wires are coiled around the arbor, in order to make sure that each coil of the wires are in the same diameter without deformation.
Once a wire is making as helical or spiral, which means the completion of the spring, the cut slide would cut the spring off. Depending on the methods of operation, the cutting process may be conducted manually or automatically.
When the spring making machine is operated manually, then there would not be a cut slide on the machine. Instead, the operator would cut the spring that is completely made off by another cutting tool by himself or herself.
In contrast, the automatically operated spring making machine would cut the springs with the cut slide of it, which is free from the requirement of an operator, and the process of the work can be smoother and faster than that by the manual force.
A spring making machine can be worked manually, semi-automatically, or automatically, depending on the required volume of the springs. There can be a simply constructed manual spring making machine that is set on the workbench, clamped by a vise, and worked by the operator.
For the semi-automatic spring making machine, the machine would be mounted on the chuck with several jaws. The semi-automatic spring making machine coils the wires and the operator cuts off the front end of the wires.
As for the automatic spring making machine, it is usually held by the 4-jaw chuck, with the interaction of the 4 jaws that is used for different purposes respectively, the process of coiling can be completely without manual force, except for the program setting by the engineers.
Here we mainly talk about the differences between the manual and the automatic spring making machine at below.
● manual spring making machine
The manual spring making machine is only operated on the X direction, which is worked horizontally. When the arbor is well-clamped on the vise, the operator should first set up the position of the wire guide, which is used for remaining the symmetry between each coil.
When the position of the wire guide is set up, the operator holds the wire guide by the one hand, and the other hand turns the handle of the vise. With the rotating of the arbor, the wire would be coiled. After the operator cut the end of the wire, then the spring is made.
● automatic spring making machine
The automatic spring making machine is operated by both the X and Y directions and totally automatically. The arbor is moved from the X axis, which further brings the wire around it moves together. With the wedge pitch slide holds the arbor in place, and the cut slide cuts the spring off from the Y direction, then a spring is made.
