Introduce the technical characteristics of the single-column hydraulic press




The single-column hydraulic press has a C-type single-arm structure and is welded with all steel plates. After welding, it is treated by tempering and aging to ensure that the body will never be deformed. The hydraulic system is located in the fuselage, with beautiful appearance and convenient operation.



It is mainly used for drawing, forming and pressing of metal products. It can also process non-metallic materials, the pressing of powder metallurgy products, the correction of shaft parts, the pressing of sleeve parts, and the shaping and trimming of metal products.



The single-column hydraulic press is equipped with an independent hydraulic and electrical control system. It adopts button centralized control, which can realize two forming processes of fixed stroke and fixed pressure, and has functions such as pressure digital display and stroke and pressure adjustment. And the single-column hydraulic press is equipped with four-column guide column guide, thereby improving product accuracy, and the guide column and piston rod are quenched with hard chrome treatment after intermediate frequency quenching, which will never rust and brush. service life of the valve. The hydraulic system adopts the domestic advanced two-way cartridge valve, the oil circuit connection adopts imported high-pressure hose, which greatly reduces the noise of the machine, and the electrical part adopts some Omron electric appliances to improve the quality of the machine system.



In addition, advanced components such as imported PLC, grating protection and man-machine interface can be configured according to user requirements. For the special requirements of customers, we can specially design and produce to meet the production process requirements of customers to the greatest extent.



The single-column hydraulic press has compact structure and beautiful appearance; it has the function of keyboard locking to prevent misoperation; it has power frequency, variable frequency operation and circuit design. With automatic reset, power-down reset function. The power consumption of the hydraulic oil pump accounts for more than 97% of the power consumption of the entire single-column hydraulic press, so reducing its power consumption is the key to energy saving of the single-column hydraulic press. The pressure and flow required by the single-column hydraulic press change in the stages of fast down, slow down, pressure holding, pressure relief return, piston ejection, piston retraction, and buffer cylinder ejection. When the oil demand of the single-column hydraulic press occurs When changing, the load pressure and flow rate are adjusted by the relief valve set at the outlet of the oil pump, while the output power of the motor remains unchanged, thus causing energy waste.



The frequency conversion speed control device is composed of a rectifier circuit, a filter circuit, an inverter circuit and a control circuit. Its function is to rectify and filter the AC power into DC power through the rectifier link, and then convert it into AC power with different frequencies through the inverter link. motor.
