https://www.smarttechmed.com/product-category/endoscope-accessories/insertion-tube/ is one of the most common processes used for manufacturing tires. However, there are some drawbacks to this method, including the heat generated by the process, which is undesirable in some cases. This article will discuss the advantages and disadvantages of https://www.smarttechmed.com/, as well as different methods such as Air bending and V-die forming. Before we get started, let’s look at what is involved in this process. This article also provides an overview of the main advantages and disadvantages of these two processes.

tyre deformation process generates heat

In the tyre deformation process, the heat generated by the tire is a consequence of mechanical energy loss, caused by internal friction. This process can be modelled using a thermo-mechanical model which is either coupled or uncoupled to temperature. In the coupled model, the temperature is assumed to have no influence on the deformation module, and the thermo-mechanical model calculates heat transfer from the deformation module by updating material properties.

Air bending

When a manufacturer needs to bend large quantities of rubber, air forming is a viable option. The process offers many advantages over conventional bending methods. Air bending can produce bends between 90 and 180 degrees without any tooling. Although it does have a limited degree of accuracy compared to coining and bottoming, it does not require retooling for different angles. It also makes forming more complex than coining.

V-die bending

One of the most important parameters in sheet metal bending is the springback angle, which is an undesirable phenomenon when a bend angle is not exactly 90 degrees. The springback angle can be influenced by several parameters, such as the punch size and the angle of the punch nose. In contrast, springback is minimal in rubber-die bending, and the bend angle can be easily controlled within a narrow range. Besides, V-die bending is an efficient process for rubber products, as it significantly reduces springback and increases the contact surface area.

Rubber-assisted stretch bending

The aim of the study is to develop a method for uniform bending of a metal die with a constant curvature radius using rubber-assisted stretch bending. This method improves the accuracy of the shaped part by imparting a tensile stress via friction on the metal die surface. This study uses finite element analysis to analyze the effects of various process parameters on the bending accuracy and deformation.
