Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, and more specifically to a dual-pump bending device. Background Technology

[0002] With the rapid development of society and the economy, factories are producing increasingly sophisticated and high-end products. This demands higher standards for equipment, among which bending machines are indispensable. The electro-hydraulic servo CNC bending machine, in particular, utilizes electro-hydraulic servo valves and linear encoders to form a closed-loop control system on both sides of the main hydraulic cylinders. This provides precise feedback and accurate slider movement, resulting in high bending accuracy and slider repeatability.

[0003] According to patent searches, the publication number is for an electro-hydraulic servo dual-pump CNC bending machine, which includes an operating table and an upper working box fixed to the surface of the operating table. A servo hydraulic pump is fixedly installed inside the upper working box, and a stamping block is provided at the bottom of the servo hydraulic pump. This invention utilizes a rotating rod to quickly move a connecting rod horizontally across the rotating rod surface by rotating a threaded sleeve fitted on the rotating rod surface. Simultaneously, a moving block moves on the upper surface of the operating table, thereby changing the size of the bending groove formed by two sets of moving blocks.

[0004] In actual use, the dual-pump CNC bending machine proposed in the above patent documents requires manual placement of the sheet metal on the surface of the bending device, followed by manual feeding and bending. Furthermore, it lacks sheet metal positioning, resulting in low stability and poor adjustability. Therefore, certain improvements are needed to address these issues. Utility Model Content

[0028] The position of the movable pressure block 17 corresponds to that of the movable base 6. Guide through holes are provided on both the left and right sides of the operating table 2.
