A small and micro pure electric servo CNC press brake carefully developed with German technology,compared with the traditional electro-hydraulic model has 4 advantages： (1)Energy saving, a month of electricity consumption is a quarter of the ordinary hydraulic press brake； (2) Environmental protection, this pure electric press brake does not use hydraulic oil, there is no oil leakage, which makes the workshop more clean and environmental protection; (3) High efficiency, this press brake is controlled by servo motor and screw, so that the control of the whole cycle is double the efficiency of the hydraulic press brake; (4) Accurate, pure electric servo press brake mainly relies on servo motor and screw rotation, so that the slider moves up and down, long-term work, its positioning accuracy can still remain accurate! More machine, details, welcome to inquire! 一. Main structure and working principle of machine tool: 1. The machine is mainly composed of frame, slide block, back stop structure, control system and mold. （1）Frame: All steel welded structure, with sufficient strength and rigidity，and through finite element analysis to simulate real load conditions to achieve the required load conditions。After welding, annealing treatment is used to eliminate the residual welding stress of the frame. （2）Slider: The machine adopts eccentric shaft guide slider structure, the overall structure is simple, convenient debugging and maintenance. （3）Control system: using NCmax CNC bending system, this system is independently developed, flexible operation, simple, no skilled operator can operate, simple program production,fast, do not need to enter the mold information in advance to process,data modification and execution on the same screen, saving time, simplifying operations,The relative position of each axis is used to record the origin, without the trouble of the origin disappearing and resetting. （4）Mold: This part is composed of two parts: upper mold component and lower mold component.The upper mold is mounted on the slide and fixed by a splint，The lower mode can be used in various forms such as single V, double V and multi-V.Molds can be segmented or customized according to user requirements. 2 .Working Principle The machine tool is driven by the servo motor directly driven screw to achieve high speed up and down and stable repeatability accuracy and high efficiency production. Machine features: *Stability and durability: All imported servo motors are used to ensure the accuracy and stability of the machinery, and are durable. *High precision and long life: screw guide are imported C5 products, high precision, excellent performance, long service life,Y-axis minimum movement setting unit :0.005mm. 3 .Energy Conservation and Environmental Protection Special power saving: The electricity difference between the all-electric servo press brake and the electro-hydraulic servo press brake is like the difference between the frequency conversion air conditioner and the ordinary air conditioner。The all-electric servo press brake automatically outputs the appropriate power according to the working condition, and the power consumption is less than 0.5kW in idle time, so it is especially power-saving. Green environmental protection: no need to use and replace hydraulic oil, ending the waste hydraulic oil pollution to the environment. Power consumption comparison between pure electric servo press brake and common electro-hydraulic press brake: Machine Type Average Power Consumption One Year Working Time One Year Electricity Consumption 40 tons full electric servo press brake about 1kW 3000 hours 3000 kilowatt-hours 40 tons hydraulic press brake about 4.5kW 3000 hours 13,500 kilowatt-hours A year can save electricity :13500-3000=10500 degrees; Five years can save electricity: 52,500 degrees! 二.Machine dimensional drawing： Main technical parameters of machine tool (single cylinder series) Main technical parameters of the machine (double cylinder series) 三.electrical apparatus control system： 1.Electrical components are mainly made of imported brands such as Schneider, which comply with international standards, are safe, reliable, and have strong anti-interference ability. The electrical control cabinet has heat dissipation function. 2. The foot switch controls bending processing and emergency stop functions. 3. The wiring of the electrical cabinet is reasonable and clear, making it easy to repair or troubleshoot 4. The electrical cabinet body is customized by OEM from a top professional control cabinet manufacturer in China Randomly equipped with standard molds, one set for upper mold and one set for lower mold (specific according to drawing requirements)
