Description

Technical Field

[0001] The utility model relates to the technical field of plate shearing machines, in particular to an oil tank filtering device for plate shearing machines. Background Art

[0002] Shearing machine is a machine that uses one blade to make a reciprocating linear motion relative to another blade to shear the plate. It uses the moving upper blade and the fixed lower blade, and adopts a reasonable blade gap to apply shear force to metal plates of various thicknesses, so that the plates are broken and separated according to the required size. Shearing machine is a kind of forging machine, and its main function is metal processing industry. The products are widely used in aviation, light industry, metallurgy, chemical industry, construction, shipbuilding, automobile, electricity, electrical appliances, decoration and other industries to provide the required special machinery and complete equipment.

[0003] Shearing machines usually use hydraulic drive to move the blades, and lubricating oil is needed to lubricate the various transmission parts of the shearing machine. The existing lubricating oil recovery and filtering device of the shearing machine will filter out metal debris sheared by the shearing machine during the oil return process. The long-term operation of the shearing machine causes the filtered metal debris to accumulate on the filter screen, resulting in poor permeability of the filter screen, affecting the oil return efficiency of the shearing machine oil tank, and may seriously cause the oil tank to overflow and cause waste. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the existing shearing machine's lubricating oil recovery and filtering device that will filter metal debris sheared by the shearing machine during the oil return process. The long-term operation of the shearing machine causes the filtered metal debris to accumulate on the filter screen, resulting in poor permeability of the filter screen, affecting the oil return efficiency of the shearing machine's oil tank, and may seriously cause the oil tank to overflow and cause waste. A shearing machine oil tank filtering device is provided.

[0005] The purpose of the utility model is achieved through the following technical solutions: a shearing machine oil tank filter device, including a shearing machine oil tank, a filter screen is installed in the shearing machine oil tank, the top of the filter screen is an oil return chamber, the bottom of the filter screen is an oil outlet chamber, an electric slide is installed in the oil return chamber, two groups of movable electromagnets are installed on the electric slide, the electromagnets are located below the return oil pipe, and chip collecting grooves are arranged at both ends of the filter screen. The electromagnets that move on the electric slide can effectively absorb metal debris in the return oil pipe. After the electromagnet absorbs the metal debris, it can move to the top of the chip collecting groove and the electromagnetic is closed. At this time, the metal debris absorbed on the electromagnet falls into the chip collecting groove for collection, which will not affect the passability of the filter screen, thereby ensuring the filtering performance of the filter screen.

[0006] A further technical solution is that a cleaning brush is installed under the electromagnet, and the cleaning brush is in contact with the surface of the filter. By setting the cleaning brush on the electromagnet, the filter can be cleaned during the movement of the electromagnet, and the impurities filtered on the filter are cleaned and collected in the chip collecting groove, thereby ensuring the filtering performance of the filter and facilitating the later cleaning of impurities.

[0007] A further technical solution is that an end cover is installed on the shearing machine oil tank, and the end cover is connected to the shearing machine oil tank by bolts. By setting the end cover and the bolts, the shearing machine oil tank can be easily disassembled, which is convenient for subsequent maintenance of the equipment in the shearing machine oil tank.

[0008] A further technical solution is that an anti-overflow groove is provided on the end cover, a liftable piston is installed in the anti-overflow groove, and a spring is installed between the anti-overflow groove and the piston. By providing the anti-overflow groove, the spring and the piston, the return oil can overflow into the anti-overflow groove, and subsequently, under the action of the spring and the piston, the lubricating oil flows into the return oil chamber, which can effectively prevent the waste caused by overflow of the lubricating oil.

[0009] A further technical solution is that a sealing protrusion which is engaged with the end cover is provided on the oil tank of the shearing machine, and the sealing between the oil tank of the shearing machine and the end cover can be improved by providing the sealing protrusion.

[0010] A further technical solution is that a transparent observation window corresponding to the chip collecting groove is installed on the shearing machine oil tank. By setting the transparent observation window, it is convenient to observe the collection of debris in the chip collecting groove, so as to clean the impurities in the chip collecting groove in time.

[0011] A further technical solution is that an oil outlet pipe is installed on the bottom surface of the oil outlet cavity.

[0012] The utility model has the following advantages: the utility model can effectively absorb metal debris in the return oil pipe by setting an electromagnet that moves on an electric slide; after absorbing the metal debris, the electromagnet can move to the top of the chip collecting groove and be electromagnetically closed, at which time the metal debris absorbed on the electromagnet falls into the chip collecting groove for collection, and will not affect the permeability of the filter, thereby ensuring the filtering performance of the filter; by setting a cleaning brush on the electromagnet, the filter can be cleaned during the movement of the electromagnet, and the impurities filtered on the filter can be cleaned and collected in the chip collecting groove, thereby ensuring the filtering performance of the filter and facilitating the cleaning of impurities at a later stage; by setting an anti-overflow groove, a spring and a piston, the return oil can overflow into the anti-overflow groove, and subsequently, under the action of the spring and the piston, the lubricating oil will flow into the return oil chamber, thereby effectively preventing the waste caused by overflow of the lubricating oil.
