- What is Rowling?
Rolling is a method that creates a cold thread on a piece, and the screw produced by this method has more strength than the screws made by turning or grinding. To create a thread on a screw using the rolling method, the piece is placed in a special position in the relevant machine, then two rollers that rotate around their axis push the screw from the surrounding, and because these rollers have a thread with a certain pitch, in fact They create a copy of themselves on the screw and thus the screw becomes a thread.

In this method, it is important to pay attention to the hardness of the desired piece (screw) in order to withstand the pressure caused by the machine, to perform the rolling operation.
Screw production can be done through various processes such as screw turning and thread cutting, 3D printing, rolling, forming, casting, molding, or even a combination of these processes.
In the rolling method, no shaving is done on the surface of the workpiece. During the cold forming process, the desired thread is created by creating a uniform and regular pressure by the forming rollers. In thread production by ordinary lathes, Dissociation has been created in the texture of metals, which will be associated with spending a lot of time and energy and reducing the quality of manufactured products. This is despite the fact that with rolling machines, by using simple labor instead of skilled labor and expensive tools, products can be produced with higher speed, quality and efficiency.
- Rolling machinery
Rolling machines generally include 3 parts: cutting machine, thread or rolling machine and rebar installation vaults: ✔️ Cutting machine: To cut the rebar in the required sizes and cut the head of the rebar fabric and prepare for the cutting stage. ✔️ Rolling machine: Rotashi and rolling - thread machine. ✔️ Rebar installation vaults: can be made in the workshop.
- Industrial use of Rowling Machine
One of the industrial uses of the rolling machine is to create a thread on the ribbed wire, which is widely used in the construction industry. In the making of this part, which is called ankle bolt, first the ribbed wire is shaved and then the thread is created on it. The production of this part takes a few minutes in the usual way and the quality of the created thread is not good. But in the production of ankle bolts by special machines, the production part is ready for threading in a few seconds.
This machine has the ability to turn rebar in a wide range of standard products with high quality and uniformity, and due to the stability of the workpiece and the rotation of the tool, there is no limit to the length of the parts. The length required to create the thread is set by the PLC controller and the turning operation is done completely automatically. The simplicity of working with this machine has made it easy to use by the workforce.
