Description

TECHNICAL FIELD

[0001] The utility model relates to saw blade quenching technical field, concretely relates to a saw blade upper and lower surface quenching oil cooling device. BACKGROUND

[0002] Saw blade is the cutting tool widely used in metal processing, wood processing, stone cutting and many other industries, and its performance directly affects the processing quality and efficiency. Quenching process is the key link to improve the performance of saw blade. Through quenching, the hardness, wear resistance and strength of saw blade can be significantly improved, thereby prolonging the service life of saw blade and ensuring cutting accuracy. In the quenching process of saw blade, oil cooling is a commonly used and effective cooling method. Oil cooling can cool the saw blade at an appropriate cooling rate during quenching, form an ideal organizational structure, and thus obtain good performance.

[0003] In the related art, the traditional saw blade oil cooling device usually adopts a relatively simple oil spraying device. The oil injection holes of the upper and lower spray trays are basically the same in specification. However, due to the influence of gravity, the oil distribution and cooling effect on the lower surface are often not as good as those on the upper surface during downward flow, resulting in differences in quenching hardness between the upper and lower surfaces of the saw blade. The upper surface has better quenching effect, while the lower surface has relatively lower quenching hardness, which cannot guarantee the consistency of the hardness of the upper and lower surfaces of the saw blade. Such hardness difference can cause uneven stress on the saw blade during use, easily leading to deformation and warping of the saw blade, reducing the cutting accuracy and service life of the saw blade, and also increasing the risk of failure of the saw blade during cutting. SUMMARY

[0004] The purpose of the utility model is to provide a saw blade upper and lower surface quenching oil cooling device to solve at least one aspect of the problems and defects in the above background technology.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] A saw blade upper and lower surface quenching oil cooling device, comprising:

[0007] A quenching oil cylinder is provided with a main oil way on one side, and the output end of the main oil way is respectively provided with an upper oil way and a lower oil way;

[0008] The output end of the upper oil way is provided with an upper spray tray, and the output end of the lower oil way is provided with a lower spray tray;

[0009] A saw blade is arranged between the upper spray tray and the lower spray tray;

[0010] A plurality of first oil injection holes are arranged on the upper spray tray, and a plurality of second oil injection holes are arranged on the lower spray tray;

[0011] A number of the second oil injection holes have a diameter smaller than a number of the first oil injection holes.

[0012] The saw blade upper and lower surface quenching oil cooling device has at least the following technical effects:

[0013] The saw blade upper and lower surface quenching oil cooling device, by setting the second oil injection hole diameter of the lower spray tray to be smaller than the first oil injection hole diameter of the upper spray tray, compared with the traditional saw blade oil cooling device, according to the principle of fluid mechanics, under the same oil pressure, reducing the diameter of the second oil injection hole can effectively improve the oil injection speed and efficiency of the second oil injection hole, so that the oil can quickly take away the heat of the lower surface of the saw blade, improve the quenching effect of the lower surface of the saw blade, make the quenching hardness of the upper surface and the lower surface of the saw blade consistent, effectively improve the performance stability of the whole saw blade, reduce the problems such as deformation and warping of the saw blade caused by the hardness difference between the upper surface and the lower surface of the saw blade, and ensure the quality of the saw blade.

[0014] As a further scheme of the utility model: the diameter of the first oil injection hole is 6mm-8mm.

[0015] Since the diameter of the first oil injection hole is 6mm-8mm, the oil sprayed by the first oil injection hole is from top to bottom, and the oil has a natural falling factor, so the oil sprayed by the first oil injection hole can quickly contact the upper surface of the saw blade, thereby taking away the quenching heat of the upper surface of the saw blade, ensuring the quenching hardness of the upper surface of the saw blade, and thus ensuring the quality of the saw blade.

[0016] As a further scheme of the utility model: the diameter of the second oil injection hole is 3mm-5mm.

[0017] Since the diameter of the second oil injection hole is 3mm-5mm, the main oil way outputs oil to the upper oil way and the lower oil way, and the oil output pressure of the upper oil way and the lower oil way is the same, but the oil output of the second oil injection hole is from bottom to top, but the diameter of the second oil injection hole is smaller than that of the first oil injection hole, so according to the principle of fluid mechanics, under the same oil pressure, compared with the first oil injection hole of the upper spray tray, the oil of the lower spray tray is better compressed by the second oil injection hole, so that the oil injection speed and efficiency of the second oil injection hole are greatly improved, so that the oil output by the lower oil way can also quickly take away the heat of the lower surface of the saw blade, improve the quenching effect of the lower surface of the saw blade, make the quenching hardness of the upper surface and the lower surface of the saw blade consistent, effectively improve the performance stability of the whole saw blade, and ensure the quality of the saw blade.

[0018] As a further scheme of the utility model: a first booster pump is arranged on the main oil way.

[0019] By setting the first booster pump on the main oil way, the pressure of the oil in the main oil way can be increased, the main oil way is the source of the upper oil way and the lower oil way, and after the oil pressure in the main oil way is increased, the oil pressure in the upper oil way and the lower oil way is also increased, so that the oil spraying speed of the upper and lower spraying discs is increased, the oil can be sprayed to the upper and lower surfaces of the saw blade more quickly, and the heat on the upper and lower surfaces of the saw blade is quickly taken away, the cooling efficiency of the saw blade is improved, and the quenching effect of the saw blade is improved.

[0020] As a further scheme of the utility model: the lower oil way is provided with a second booster pump.

[0021] Due to the influence of gravity and other factors, the lower surface of the saw blade is more difficult to achieve efficient cooling than the upper surface, and by setting the second booster pump on the lower oil way, the pressure of the oil in the lower oil way can be increased, so that the oil spraying speed and pressure of the lower spraying disc are increased, the heat on the lower surface of the saw blade is taken away more effectively, the cooling effect of the lower surface of the saw blade is further improved, and the consistency of the quenching hardness of the upper and lower surfaces of the saw blade is ensured.

[0035] Specifically, the saw blade upper and lower surface quenching oil cooling device, by the second oil injection hole 107 on lower spray tray 105 diameter is set to be less than the first oil injection hole 106 diameter of upper spray tray 104, compared with traditional saw blade oil cooling device, according to the principle of fluid mechanics, under the same oil pressure, the diameter of the second oil injection hole 107 can be effectively improved the oil injection speed and efficiency of the second oil injection hole 107, so that the oil can quickly take away the heat of the lower surface of the saw blade 2, improve the quenching effect of the lower surface of the saw blade 2, make the quenching hardness of the upper surface and the lower surface of the saw blade 2 tend to be consistent, effectively improve the performance stability of the saw blade 2, reduce the saw blade deformation, warping and other problems that may be caused by the hardness difference between the upper surface and the lower surface of the saw blade 2, ensure the quality of the saw blade 2.

[0036] According to the embodiment of the utility model, the diameter of the first oil injection hole 106 is 6mm-8mm.

[0037] Specifically, since the diameter of the first oil injection hole 106 is 6mm-8mm, the oil ejected from the first oil injection hole 106 is from top to bottom, and the oil has a natural falling factor, so the oil ejected from the first oil injection hole 106 can quickly contact the upper surface of the saw blade 2, thereby taking away the quenching heat of the upper surface of the saw blade 2, ensuring the quenching hardness of the upper surface of the saw blade 2, thereby ensuring the quality of the saw blade 2.

[0038] Further, the diameter of the second oil injection hole 107 is 3mm-5mm.

[0039] Specifically, since the diameter of the second oil injection hole 107 is 3mm-5mm, the main oil path 101 outputs oil to the upper oil path 102 and the lower oil path 103, the oil output pressure of the upper oil path 102 and the lower oil path 103 is the same, and the oil output of the second oil injection hole 107 is from bottom to top, but the diameter of the second oil injection hole 107 is smaller than that of the first oil injection hole 106, so according to the principle of fluid mechanics, under the same oil pressure, compared with the first oil injection hole 106 of the upper shower disc 104, the oil of the lower shower disc 105 is better compressed by the second oil injection hole 107, so that the oil injection speed and efficiency of the second oil injection hole 107 are greatly improved, so that the oil output by the lower oil path 103 can also quickly take away the heat of the lower surface of the saw blade 2, improve the quenching effect of the lower surface of the saw blade 2, make the quenching hardness of the upper surface and the lower surface of the saw blade 2 consistent, effectively improve the performance stability of the whole saw blade 2, and ensure the quality of the saw blade 2.
