Single column hydraulic press maintenance and maintenance knowledge

by:WORLD     2022-11-12
Single-column hydraulic press (single-arm hydraulic press, C-type hydraulic press), the body is a c-type cantilever structure, and the whole adopts a welded solid open structure, which can make the explosion enough just wake up and have the most convenient operation space, small structure, stable work , fast speed, high efficiency, low energy consumption, simple operation and so on.



The single-column hydraulic press has a four-column guide rail, which improves the accuracy of the product, and implements hard chrome plating after the intermediate frequency quenching of the guide rail and piston rod to prevent rust. A unique filter device is set at the oil supply port of the oil pump to ensure the oil pump and valve lifespan. The service life of the single-column hydraulic press is related to regular maintenance. Regular maintenance can eliminate the problems existing in the single-column hydraulic press operating system. This article introduces how to maintain the single-column hydraulic press.












The single-column hydraulic press is mainly suitable for the stretching, press forming, stamping, press fitting and other technologies of metal products. It can also process non-metallic materials, stamping of powder metallurgy products, correction of shaft parts, stamping of complete sets of parts and shaping of metal products. , trimming and other technologies.












Before starting the single-column hydraulic press:

1. Check whether the single-column hydraulic oil pool, oil level, and oil mark meet the specified standards. If not, please add oil immediately.



2. Check the softness of the button of the single-column hydraulic press and the presence or absence of card resistance.



3. Check whether the grounding wire of the single-column hydraulic press motor is loose, falling off, or damaged. If it is loose, fastened, fallen off, or damaged, the maintenance personnel should be notified.



4. Check whether the safety protection device of the single-column hydraulic press is completely reliable.



5. Check whether the handle of the single-column hydraulic press is flexible.



6. Tighten the loose nuts of the single-column hydraulic press.












Single-column hydraulic press in operation:

1. Start the hydraulic pump of the single-column hydraulic press to check whether the function of the hydraulic pump is good, and whether the sealing parts and pipelines are blocked or leaked.



2. Check whether the action of the limit switch of the single-column hydraulic press is good, and whether the positioning of the collision block is normal.



3. Pay attention to the temperature rise of each running part of the single-column hydraulic press and whether the sound is normal or not.












After the single-column hydraulic press is stopped:

1. Check and clean the movable parts of the single-column hydraulic press.



2. Set each operating handle (switch) of the single-column hydraulic press to neutral (zero).



3. Inspect, clean and organize work surfaces and work areas.












Maintenance of hydraulic system of single-column hydraulic press:

1. The hydraulic system circuit connection of the single-column hydraulic press adopts imported high-pressure hose, which greatly reduces the mechanical noise.



2. Wipe the connecting parts of the single-column hydraulic press, and lubricate it immediately to realize the softness of operation.



3. Check the upper and lower covers of the single-column hydraulic press, the motor base, and the fixing screws of the hammer to confirm that they are fastened firmly.



4. Clean the single-column hydraulic oil pump and filter.



5. Scrub, check, and dredge the circuit of the single-column hydraulic press, lubricate well, and eliminate oil leakage.



6. Maintenance of single-column hydraulic machine electrical system:



7. Wipe off the dust outside the single-column hydraulic press motor and electric box.



8. Clean, check, and organize the circuit of the single-column hydraulic press to achieve reasonable layout, firm connection and safety.












After cleaning the inside and outside of the toolbox of the single-column hydraulic press, clean and organize all the items and tools for easy removal. The principle of avoiding collision is to layer, classify and neatly arrange them in the toolbox.

Record the main problems of the single-column hydraulic press solved and unsolved during the maintenance in the file, as the basis for the next maintenance or inspection plan data.
