Before using the pipe bending machine, the length of the elbow should be taken into consideration. The galvanized steel pipe must comply with national standards. Whether using a bending machine or manually bending the pipe, the axis will not change regardless of how the pipe is bent. In other words, as long as the center line of the bent pipe is maintained, the pipe will stay bent. How to measure the length of the elbow with the bending machine? Otherwise, it is easy to break. Hot-dip galvanized steel pipes are divided into cold and hot-dip galvanized steel pipes, and the country promotes the use of the former. After bending, the length of the outer and inner surfaces of the pipe decreases, but the length of the axis remains unchanged.
On the base of the bending machine, the bending specifications adjusting device includes two sets of symmetrically arranged adjustment components, including adjusting levers, control rods, and their force wheels. The control rod passes through the base and is connected to them for rotation. By using the bending specification adjusting device provided by this invention patent, the distance between the force wheels can be conveniently adjusted by adjusting the components, thus improving the specifications of the elbows. The outer and inner ends of the control rod are respectively connected to the adjusting lever and the force wheel, and the force wheel is connected to the base for driving. The rotation of the adjusting lever promotes the movement of the control rod, ultimately ensuring the force wheels to stay in contact. The accuracy of pipe bending is a critical factor affecting the quality of bent pipes throughout the manufacturing process.
In addition to specifications and operating procedures, the customer is also required to choose the bending wheels according to their control and pipeline management conditions when using elbows. During the entire bending process, the elbow plays a role in structural mechanics, and its wall thickness directly influences the quality and application of the product. Nowadays, the raw materials for elbow production and processing are often relatively long, and materials such as cast steel, stainless steel plates, and aluminum alloy profiles can be used throughout the manufacturing process. The structure of the products is completed by the bending and guiding molds, with the two molds connected to each other.
