Increasing the Energy Efficiency of Sheet Bending Equipment

It is shown that energy saving and energy efficiency increase should be considered as one of the main sources of future economic growth. The equipment that is used for the manufacture of products in the press shops has powerful electric motors. They are the main consumers of electrical energy. Replacing powerful electric motors with low-power ones will lead to energy savings. Crank bending machines are mainly used in mass production press shops. This calculation method makes it possible to control the deformation force and decrease it to reduce the overall operation of the press and its energy consumption. This will allow the use of less powerful presses for bending. It is shown that deformation occurs in two stages of sequential loading of the workpiece, which leads to splitting up the deformation process and, thereby, to decreasing the required force compared to the initial one. Using these analytical dependences for calculating the geometric dimensions of the resulting rift, it is possible to simplify the structure and design of the deforming tool, create a method for calculating technological and design parameters. The minimum force of the buffer, which must be used in the first operation, can be calculated based on the condition of maintaining the straightness of the workpiece and overcoming the resistance forces.
