Description

Technical Field

[0001] The utility model relates to the technical field of blades, and more specifically, to a cubic boron nitride composite blade. Background Art

[0002] Cubic boron nitride is a superhard material similar to diamond, with extremely high hardness and wear resistance. It is suitable for processing hard materials such as steel, cast iron, alloy, etc. By coating the surface of the blade with cubic boron nitride, the cutting performance and service life of the blade can be significantly improved. The existing blade has a small contact area with the blade body, which is difficult to weld firmly and the blade is easy to fall off.

[0003] After searching, a Chinese patent with announcement number CN216365216U discloses a composite blade. Since the mounting part and the cutting edge part are separated, the mounting part can use some lower-priced materials while ensuring hardness and toughness; since the thickness of the cutting edge part can also be reduced due to the setting of the connecting piece, the production cost of the composite blade can be reduced by more than 50% compared with the past, and the service life of the blade is longer, which has a good market prospect.

[0004] When the composite blade is in use, the connecting piece is respectively welded to the cutting edge and the mounting portion to fix the cutting edge and the mounting portion. However, the composite blade is an integrated structure. When the cutting edge is damaged, the entire blade needs to be replaced, resulting in high maintenance costs. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a cubic boron nitride composite blade, aiming to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cubic boron nitride composite blade, comprising a blade body and a blade handle, and one side of the blade handle is fixedly connected to the blade body, a first blade is movably arranged at the bottom of the blade body, a first connecting component is arranged on the first blade, the first connecting component comprises a first threaded rod and a first threaded sleeve, the bottom end of the first threaded rod is fixedly connected to the first blade, and the top end of the first threaded rod passes through the blade body, the first threaded sleeve is movably sleeved on the first threaded rod, a second blade is movably arranged on one side of the blade body, and the second blade and the first blade are both coated with cubic boron nitride, a second connecting component is arranged on the second blade, the second connecting component comprises a second threaded rod and a second threaded sleeve, the bottom end of the second threaded rod is fixedly connected to the second blade, and the top end of the second threaded rod passes through the blade body, and the second threaded sleeve is movably sleeved on the second threaded rod.

[0007] Furthermore, a first gasket is movably provided on the top of the first blade, and the first gasket is in contact with the blade body.

[0008] It can be seen that in the above technical solution, the stability between the first blade and the blade body can be improved by the first gasket.

[0009] Furthermore, first clamping blocks are fixedly connected to both sides of the first blade, and the two first clamping blocks are both located in the blade body.

[0010] It can be seen that in the above technical solution, the stability between the first blade and the blade body can be further improved by the first clamping block.

[0011] Furthermore, a second gasket is movably provided on one side of the second blade, and the second gasket is in contact with the blade body.

[0012] It can be seen that in the above technical solution, the stability between the second blade and the blade body can be improved by the second gasket.

[0013] Furthermore, the top and bottom ends of the first blade are fixedly connected to second clamping blocks, and the two second clamping blocks are both located in the blade body.

[0014] It can be seen that in the above technical solution, the stability between the second blade and the blade body can be further improved by the second clamping block.

[0015] Furthermore, an isolation component is provided on the cutter body, and the isolation component includes an isolation sleeve, a slider, a screw rod and a handle.

[0016] Furthermore, the top end of the slider is fixedly connected to the isolation sleeve, and the slider is movably sleeved on the screw rod, both ends of the screw rod are movably connected to the knife body through bearings, and the handle is fixedly sleeved on the screw rod.

[0017] Technical effects and advantages of the utility model:

[0018] 1. The utility model provides a first blade and a second blade, so that the blade as a whole has two cutting modes, and has a wide range of applications. The first thread sleeve is rotated and kept away from the first threaded rod, thereby releasing the fixation between the first blade and the blade body, and the first blade is repaired and replaced. The second thread sleeve is rotated and kept away from the first threaded rod, thereby releasing the fixation between the second blade and the blade body, and the second blade is repaired and replaced. The structure is simple, and there is no need to replace the entire blade, which effectively reduces the maintenance cost.

[0019] 2. In the utility model, when the second blade is not needed, the handle is turned to drive the screw to rotate. Since the slider is threadedly connected to the screw, the knife body limits the rotation of the slider, so the screw can drive the slider to move horizontally to the right, thereby driving the isolation sleeve to move horizontally to the right, so that the second blade is located in the isolation sleeve, and the second blade is isolated. The operation is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
