Description

Technical Field

[0001] The utility model relates to the field of hydraulic presses, in particular to a fine blanking servo hydraulic press. Background Art

[0002] The fine blanking servo hydraulic press is an energy-saving and efficient hydraulic press that uses a servo motor to drive the main transmission oil pump, reduces the control valve circuit, and controls the hydraulic press slide. It is suitable for stamping, die forging, press fitting, straightening and other processes. Compared with ordinary hydraulic presses, the servo hydraulic press does not contain proportional servo valves or proportional pumps in the overall control of the system. The servo-driven hydraulic press has the advantages of energy saving, low noise, low temperature rise, good flexibility, high efficiency, and convenient maintenance. It can replace most of the existing ordinary hydraulic presses and has a broad market prospect. Compared with traditional hydraulic presses, the energy-saving effect is significant. According to different processing techniques and production rhythms, the servo-driven hydraulic press can save 30% to 70% of electricity compared with traditional hydraulic presses.

[0003] After searching, the applicant found that a Chinese patent disclosed "a servo fine-blanking hydraulic press", and its announcement number is "CN214160617U". The patent mainly provides a fixed plate, an electric push rod, a driving motor, a brush and a rotating rod. After the hydraulic press finishes processing the object, some debris will remain on the workbench of the hydraulic press. The electric push rod can be started first to push the fixed plate and the rotating rod upward together until the brush is all on the top surface of the workbench, and then the driving motor rotates the rotating rod. The brush outside the rotating rod rotates at a high speed on the workbench to clean, and all the debris on the table is cleaned out of the outside of the hydraulic press. Then the electric push rod drives the brush to be retracted into the inside of the workbench, so that the workbench can be automatically cleaned without affecting the normal operation of the hydraulic press.

[0004] The device in the above patent can clean the workbench to a certain extent after the hydraulic press has finished working. However, when the device in the above patent is extruding steel plates, it can only use manual placement of steel plate raw materials. Then, after stamping, it is necessary to manually remove the extruded debris and collect the raw materials. First, manual picking is unsafe. Secondly, picking up the materials every time stamping is performed delays the stamping time and reduces production capacity. Utility Model Content
