The similaritiesdifferences between rollingbending machines
发布时间：2022-11-17 点击浏览：次
A roll bending machine is an equipment that can bend pipes and tubes with a larger centerline diameter. It is achieved through opposite rollers, in which the pipe is slotted and processed back and forth until the desired curvature is achieved. Usually, pipes are fed through three triangular arranged rollers; The arc of the circle is determined by adjusting the third opposite roller. These machines range in size from desktop to heavy-duty machinery. Some are manually cranked, while others provide digital control for repetitive work during the production process. Metal plates can be made into cylinders and cones using a roll bending machine, or other solid materials can be repeatedly passed through the roll bending machine during the bending process of gradually changing the material axis. This process maintains the integrity of the pipeline without causing deformation to the cross-section.
Usually, three or four rollers complete this task. The double clamping machine provides adjustable roller rolling on a fixed shoe upper, while the initial clamping type required alternating bending of the pipe ends. The device generates slight arcs on various pipe passes and lengths of pipe coils and pipe coils. The technology of operating the roll bending machine must take into account the pipeline material to allow for the pressure required to generate the desired arc. A geometric arrangement of a cubic polynomial that approximates an arc between a roller and a pipe segment subjected to force. After leaving the roller, the plastic and elastic deformation generated is relieved through the rebound effect. This is represented by the elastic flexibility of a given material relative to its ductility, that is, the reciprocal of stiffness.
Some metals have a higher plasticity elasticity ratio and are easier to form. Although bending is still a gradual process, the improvement of machine capabilities has increased production speed. The effectiveness of roller bending machines in handling billet thickness and gauges depends on the interaction between machine power and material stiffness. This device is capable of converting metal plates into cylinders and cones of different ovality.
Circular, square or rectangular pipes, angle steel, all flat pipes can be operated through this workpiece. The correct bending machine for a given process is determined by several key factors. These factors include the expected thickness, width, and tolerance of the target material. The minimum expected diameter is also included, as small diameter pipes will harden during multiple passes of rolling, and the size of the bending roller depends on the yield point range of the material and the force required to deform it. This will also be affected by the surface of the bent pipe; During the bending process of rectangular pipes along their narrow edges in a flat or hard manner during production, it is also necessary to evaluate the scope of production operation and the completion time of the operation.
