Description

Technical Field

[0001] The utility model relates to the technical field of workpiece oil immersion, in particular to an automatic workpiece oil immersion machine. Background Art

[0002] Workpiece oiling is a common operation during metalworking and manufacturing, especially after heat treatment and surface treatment. The purpose of oiling is usually to provide lubrication, rust prevention or improve the surface characteristics of the workpiece. Here are some detailed information about workpiece oiling:

[0003] Lubrication: Oil immersion can ensure that the workpiece remains in a good lubrication state during transportation and use, reducing wear and failure.

[0004] Rust prevention: Oil immersion can form a protective film on the surface of the workpiece to prevent contact with air and moisture, thereby preventing rust.

[0005] Improved surface characteristics: Certain types of oils, such as cutting oils, can help improve the surface quality of a workpiece and reduce burrs and scratches during the cutting process.

[0006] Cooling: During heat treatment, oil immersion of the workpiece can help to cool it quickly and reduce thermal stress and deformation.

[0007] Cleaning: In some cases, immersion oil can also help clean the workpiece surface and remove contaminants generated during the machining process.

[0008] Improve processing efficiency: Oil immersion can reduce friction during processing and improve production efficiency.

[0009] Protection: For some delicate or high-value workpieces, oil immersion can be used as a protective measure to prevent damage during transportation and storage.

[0010] At present, when the workpiece is immersed in oil, impurities such as iron filings on the outer surface of the workpiece will fall into the oil as the oil immersion proceeds, resulting in impurities in the oil. The oil used for oil immersion is generally recycled. During recycling, the impurities contained in the oil will change the quality of the oil, resulting in the deterioration of the oil quality, and the workpiece after oil immersion cannot meet the requirements; although an oil filter is used to filter the oil, most of the impurities contained in the oil will enter the oil filter, and the filter element of the oil filter needs to be replaced frequently, which shortens the service life of the filter element of the oil filter and affects the working efficiency of the oil immersion machine. Based on this, an automatic workpiece oil immersion machine is proposed. Utility Model Content

[0012] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0013] A workpiece automatic oil immersion machine comprises a guide platform and an oil immersion chamber and an oil tank installed on both sides of the guide platform, wherein the oil immersion chamber and the oil tank circulate oil through an oil filter, and further comprises: a waste collecting box arranged in the oil tank, wherein the waste collecting box with an opening at the upper end corresponds to the oil inlet end of the oil tank, wherein a filter screen is slidably connected in the waste collecting box, a vibration spring is fixedly connected to the bottom of the filter screen, and the bottom of the vibration spring is fixedly connected to the inner bottom of the waste collecting box; a cleaning plate slidably connected in the waste collecting box, wherein the plane where the cleaning plate is located is perpendicular to the plane where the filter screen is located, and the bottom of the cleaning plate is in contact with the top of the filter screen.

[0022] Compared with the prior art, the utility model provides an automatic workpiece oil immersion machine, which has the following beneficial effects:

[0023] 1. The automatic workpiece oil immersion machine, through the coordinated use of the waste box and the filter, can filter the oil entering the oil tank to a certain extent, preventing the impurities in the oil from entering the oil filter machine, causing the filter element of the oil filter to accumulate a large amount of impurities such as iron filings in a short period of time, thereby extending the service life of the filter element and reducing the impurities in the oil, making it easier to clean the impurities in the oil.

It also includes a cylinder 10 fixedly connected to the guide platform 1, and a slide plate 11 is fixedly connected to the top of the oil immersion frame 12. The slide plate 11 extends into the guide platform 1 and is fixedly connected to the output end of the cylinder 10.

[0036] When in use, first place the storage box containing the workpieces on the conveying roller 4, then start the cylinder 10 so that the slide plate 11 drives the oil immersion rack 12 to slide upward until the rotating roller 13 and the conveying roller 4 are in the same plane, then drive the conveying roller 4 to rotate by the driving motor and the like to convey the storage box to the platform formed by the rotating roller 13, and start the cylinder 10 again so that the slide plate 11 drives the oil immersion rack 12 to slide downward, so that the storage box containing the workpieces enters the oil immersion chamber 2, and the oil in the oil immersion chamber 2 will completely submerge the workpieces, completing the oil immersion operation;

[0037] When the specified oil immersion time is reached, the cylinder 10 is started so that the slide plate 11 drives the oil immersion rack 12 to slide upward until the rotating roller 13 and the conveying roller 4 are in the same plane again, and then the storage box with the workpieces that have been immersed in oil is pushed away from the platform formed by the rotating rollers 13 to the material guide table on the other side, or the storage box that has been immersed in oil is pushed against the storage box that has been immersed in oil and transferred to the other side by the storage box in front that has not been immersed in oil, thereby realizing the automatic oil immersion operation of the workpiece, and facilitating the removal of the workpieces that have been immersed in oil, thereby improving the oil immersion efficiency;

[0040] When the oil in the oil immersion chamber 2 needs to be replaced, the oil in the oil immersion chamber 2 is pumped into the oil tank 5 by starting the oil pump in the oil discharge pipe 14. When entering the oil tank 5, the impurities in the oil are first filtered by the waste box 16 and the filter screen 20. Before filtering the impurities, the motor 17 is started to make the reciprocating screw rod 18 drive the cleaning plate 19 to slide back and forth along the top of the filter screen 20 to dredge the filter screen 20. When the cleaning plate 19 slides to a portion where the impurities are thicker, the filter screen 20 will be squeezed to slide downward under the action of the impurities, so that the vibration spring 21 is compressed.

[0041] The oil entering the oil tank 5 is filtered to a certain extent, preventing impurities in the oil from entering the oil filter 7, which would cause a large amount of impurities such as iron filings to accumulate in the filter element of the oil filter 7 in a short period of time, thereby extending the service life of the filter element and reducing the impurities in the oil, making it easier to clean the impurities in the oil. At the same time, the oil and impurities initially discharged into the oil tank 5 can be separated, preventing impurities from being immersed in the oil for a long time and affecting the quality of the oil.
