Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic presses, in particular to a four-column high-speed numerically controlled hydraulic press. Background Art

[0002] The four-column high-speed CNC hydraulic press is an advanced equipment for metal forming processing. It combines the four-column structure and CNC technology to achieve high-speed, precise and automated processing operations. The four-column high-speed CNC hydraulic press adopts a four-column structure, which is supported and fixed by four vertical columns on the workbench and slider. This structure provides stable rigid support and guidance in the vertical direction of movement, which is very important for metal forming operations that are subjected to high pressure and high load. At the same time, the four-column high-speed CNC hydraulic press uses a hydraulic system to provide power and control. The hydraulic system usually includes components such as the main cylinder, hydraulic pump, oil tank and hydraulic control valve. Through the work of the hydraulic system, functions such as the adjustment of processing force, the up and down movement of the slider and the fixing of the workbench can be achieved, and the four-column high-speed CNC hydraulic press is also equipped with an advanced CNC system that can accurately and programmably control the processing process. CNC technology makes the operation more efficient, precise and automated, and can accurately control parameters such as the position, pressure, speed and processing process of the slider, thereby realizing metal forming of complex shapes.

[0003] After searching, the existing patent (Announcement No.: CN216461489U) discloses a four-column servo motor high-speed hot forging hydraulic press, which relates to the technical field of hydraulic presses. The chassis and the servo motor are arranged side by side on the same horizontal plane, and a hydraulic system is arranged on the top of the servo motor, and the hydraulic system is connected to the servo motor by transmission. A workbench and four columns are arranged on the chassis, and the four columns are distributed in an array. The bottom of the column is connected to the workbench, and a movable crossbeam is arranged in the middle of the column. The utility model adopts optimized design, humanized operation, high overall machine operation efficiency, compact structure, good machine rigidity, strong resistance to lateral force, high processing and assembly precision, good guiding performance, and adopts servo motor CNC microcomputer controller control, system integrated control, high precision adjustment and control precision, and has good machine function and machine effect. The machine function is manifested in servo motor control, flywheel, bushing, auto parts, hardware tools and other precision hot forging; the overall practicality is strong and has great market promotion value.

[0004] However, in the actual use of the above solution, the mold cannot be quickly replaced, which will increase the downtime of the production line because each mold replacement takes a lot of time. This will directly affect production efficiency, reduce the overall production capacity and utilization of the production line, and the inability to quickly replace the mold will limit the flexibility and adaptability of the production line. If products of different shapes or sizes need to be produced, and mold replacement is difficult, it will not be able to meet market demand in a timely manner, affecting the company's competitiveness and market share.

[0005] In view of this, the utility model proposes a four-column high-speed CNC hydraulic press. Utility Model Content
