Significance of Hydraulic Plate Shears Energy Saving Design for Hydraulic System

The working characteristics of the hydraulic transmission system of the hydraulic shearing machine are as follows: when shearing, the system pressure increases and the flow rate decreases; When idling, the speed is high, the pressure is low, and the flow value increases. When cutting, the presser foot first presses the plate, then cuts. In the hydraulic system, because of various unnecessary losses, the system is hot. In order to maintain the ideal oil temperature, we have to take cooling measures, thus increasing the reactive power consumption of energy. Therefore, if the energy-saving consciousness is integrated into the design of hydraulic system, the energy-saving effect of reducing power is better than the energy-saving measures in use.

With the increasing shortage of energy, the energy-saving design of hydraulic shears is undoubtedly of great significance. The current energy-saving measures mainly focus on the analysis and recovery of energy consumption, which is usually achieved through the accumulator, while the analysis of energy consumption mainly focuses on the power components and actuators to reduce energy consumption.

Requirements of hydraulic system: sheet metal can only be cut off with tool rest after compression, that is, it must be broken in sequence; When shearing, there is a pressure maintaining circuit; The tool holder needs to move in parallel, that is, a synchronous ring is needed to keep the shear angle unchanged.

Hydraulic shears should keep proper viscosity. Viscosity is the amount of frictional resistance between molecules when oil flows. When the viscosity is too high, it will increase the transmission resistance in the pipeline. Increase the energy loss in the working process, increase the no-load loss of the main engine, increase the temperature quickly, high working temperature, the main pump suction end may appear "cavity" phenomenon; The viscosity of the hydraulic oil is too small to guarantee the good lubrication condition of the shearing machine, which aggravates the wear of the hydraulic system parts of the hydraulic shearing machine, increases the leakage of the system, and reduces the solvent efficiency of the oil pump.

At present, the transformation of hydraulic shear system mainly focuses on the improvement of circuit design and the selection of hydraulic components. Analysis of hydraulic system from the angle of energy saving

At present, the transformation of hydraulic shear system mainly focuses on the improvement of circuit design and the selection of hydraulic components. The design pressure of the hydraulic system is optimized from the perspective of energy saving. On the premise of ensuring the requirements of the existing design parameters, the loop efficiency of the system can be very high, and it can save energy to a great extent, so that the shears can meet the national energy-saving policy, and improve the market competitiveness of enterprises. This paper makes a beneficial exploration on the energy-saving transformation method of the existing plate shears.
