Manhart What is the working principle of the downward bending machine?

The working principle of the downward bending machine mainly involves the synergistic effect of the hydraulic system and mechanical system, as well as the precise control of the operation process by the control system. Here is a detailed explanation:
###The function of hydraulic system
*Core components: The hydraulic system is the core part of the bending machine, mainly composed of hydraulic cylinders, hydraulic pumps, hydraulic valves, and other components.
*Working principle: During operation, the hydraulic pump sends hydraulic oil into the hydraulic cylinder, generating pressure. These pressures are transmitted to the lower mold (i.e. bottom template) of the bending machine through the control of hydraulic valves.
** * Function Implementation * *: With the injection of hydraulic oil, the lower mold is subjected to a downward driving force, which clamps and holds the metal plate with the top template above, thereby achieving bending processing.
###Collaboration of mechanical systems
*Structural composition: The mechanical system of a bending machine usually includes parts such as the bed, slider, and rear pushing mechanism. The bed serves as the basic support structure, carrying the weight of the entire equipment and maintaining stability.
*Sliding block movement: The sliding block is driven by the hydraulic system to achieve up and down movement. In the downward bending machine, the direction of the slider’s movement is downward, which drives the lower mold to cooperate with the top mold to complete the bending action.
** * Rear pushing mechanism * *: This mechanism is used to fix the metal sheet and push it to move under the slider, ensuring that the sheet remains stable during the bending process.
###Accurate control of the control system
*Control method: The control system usually uses devices such as PLC (Programmable Logic Controller) and touch screen to control the operation of mechanical and hydraulic systems through preset programs.
** * Parameter Settings * *: Users can input the desired bending angle, sheet thickness, and other parameters through the touch screen, and the control system adjusts the pressure of the hydraulic system and the movement speed of the slider based on these parameters.
*Real time monitoring: The control system can also monitor various parameters and status during the bending process in real time, ensuring the safe operation of the equipment and the achievement of machining accuracy.
###Characteristics of downward bending machine
** * Easy to operate * *: As the lower mold is directly driven by the hydraulic system, the operation of the lower bending machine is relatively simple and easy to master.
*Easy to control: Through the precise control system and hydraulic system, the downward bending machine can achieve precise bending processing of metal sheets.
*Wide applicability: The downward bending machine is particularly suitable for bending long metal sheets and can meet the production needs of different industries and fields.
In summary, the working principle of the downward bending machine is to drive the bottom template to move downward through the pressure of the hydraulic system, and to clamp and bend the metal sheet in conjunction with the top template. At the same time, the precise control system and mechanical system work together to achieve high-precision and efficient processing.
