Does shearing machine need to be lubricated?

The shearing machine is an automatic processing equipment that precisely controls the size of the sheet metal processing, performs automatic cycle shearing processing of metal sheets, and transports to the next step by a feeding cart. The shearing machine is used on the production line to cut the sheet metal, collected by the feeder, and automatically load to the production line.

How to choose an appropriate knife for shearing machine?

The material performance of the blade of the shearing machine is the basic factor that affects the surface quality, cutting efficiency and lifespan. The performance of the tool depends mostly on the material, the geometric parameters, and whether the selection and design of the tool structure are reasonable.

There is the reference sense for the price of shearing machine blades You can first know the market prices of the raw materials used in the production of shear blades. Then, compare the quotations of shear blade manufacturers.

In the production of shears blades, it is worth noting heat treatment though each process is important. A qualified shearing machine blades must be quenched in the furnace at least twice to achieve the same hardness. The cutting edge is tough but not brittle, which has a long-lasting wear-resistant effect.

Generally, the parallelism of the shearing machine blades is 0.03mm and the thickness of the full length cannot exceed 0.03mm. You can use measuring tools to compare the errors of the two ends of a single piece. Then, measure the accuracy of the whole set of blades. Pay attention to see if there is no gap at the joint.

Does shearing machine need to be lubricated?

The shaft sleeve of shearing machine should be lubricated. Use a small amount of calcium-based grease oil gun. Shearing machine shears plates of different thicknesses, all need to adjust different gaps.

The cylinders of the shearing machine should have lubrication. Adopt medium amount of calcium-based grease oil gun. Shearing machine oil cylinder is the source of power, acting on the oil cylinder to drive the movement of the tool holder. It is necessary to be lubricated when the backgauge of shearing machine do back-and-forth adjustment.

The sliding nut of the backgauge of the shearing machine should be lubricated. Smear medium amount calcium-based grease. The backgauge motor drives the nut to complete the adjustment of the backgauge.

The upper and lower ends of the return cylinders of the shearing machine need lubricating. Make use of small amount of calcium-based grease oil gun. They are filled with pure nitrogen under pressure. It is the device to complete the return stroke after the shearing machine finishes cutting.

How to change the oil of shearing machine?

When the oil working time on the shearing machine reaches 2,000 hours, it needs to be replaced. The cycle for each subsequent replacement is 4,000 hours or two years.

To prevent the oil of the CNC shearing machine from infecting the environment, clean around the fuel tank. Then, remove the fuel tank cover and the oil inlet and outlet pipes.

The oil should be changed when the oil temperature is still hot and the slide block of the CNC shearing machine is at the top dead center.

Clean the oil inside the tank with clean cloth and transparent solvent. Replace with a new filter. Add new oil.

After changing the oil, start the deep well pump to circulate oil for about one hour before starting the CNC shearing machine.

Attention must be paid to the waste oil cleaned out in a unified and centralized treatment, instead of discharging directly into the natural environment to cause pollution.
