1. One point at the upper and lower ends of the left and right return cylinders

Lubrication method: oil gun lubrication amount: small (running for 16 hours/time) Lubricant model: calcium base grease (butter) left and right return cylinders are filled with a certain pressure of pure nitrogen, which is a device to complete the return action of the hydraulic plate shears after cutting. Frequent return movement requires frequent lubrication.

2. One point on the left and one point on the right of the rear retaining sliding nut

Lubrication method: coating lubrication amount: medium (8 hours/time of operation) Lubricant model: calcium base grease (grease), mainly driven by the rear stopper motor to the nut, to complete the adjustment of the rear stopper. The back and forth adjustment of the rear stopper of the hydraulic shearing machine makes lubrication necessary.

3. One point on the left and one point on the right of the swing fulcrum of the upper tool rest

Lubrication method: oil gun Lubrication amount: small (24 hours/time of operation) Lubricant model: calcium base grease (butter)

The fulcrum of hydraulic plate shears' swing shearing is closely related to each shearing, and each action needs to be extremely smooth, which cannot be separated from regular lubrication.

4. One point on the left and right of the clearance adjusting shaft sleeve

Lubrication method: oil gun Lubrication amount: small (48h/time operation) Lubricant model: calcium base grease (butter)

When the hydraulic plate shears cut plates of different thicknesses, different clearances need to be adjusted, and the shaft sleeve of the clearance adjusting shaft needs to be lubricated frequently.

5. One point for left and right oil cylinders

Lubrication method: oil gun Lubrication amount: medium (8 hours/time of operation) Lubricant model: calcium base grease (butter)

The oil cylinder of the hydraulic plate shears is the source of the shearing power of the hydraulic plate shears. The acting force on the oil cylinder drives the tool rest to move. The stability of its performance requires regular lubrication.
