Description

Technical Field

[0001] The utility model relates to the technical field of cemented carbide blades, in particular to a cemented carbide blade with a vibration reduction function. Background Art

[0002] Alloy is a substance with metallic properties that is synthesized by two or more metals and metals or non-metals through a certain method. It is generally obtained by melting into a uniform liquid and solidifying. Alloys have excellent properties such as low melting point, high hardness, high strength, strong corrosion resistance, and heat resistance. Therefore, alloy materials are widely used in many fields of science and life, especially cemented carbide. Among them, cemented carbide blades are one of the commonly used forms;

[0003] The existing cemented carbide blades do not have a vibration reduction function. Most machine tools are equipped with vibration reduction devices. However, the blades do not have a vibration reduction function, which will cause the spindle to vibrate more when driving the blade to rotate, resulting in reduced cutting accuracy. In addition, the existing cemented carbide blades are inconvenient to maintain, which will cause the blades to overheat during use and reduce their service life. Therefore, we propose a cemented carbide blade with a vibration reduction function. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a carbide blade with a vibration reduction function, which can be very convenient for maintenance and can effectively reduce vibration, and can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cemented carbide blade with a vibration reduction function, comprising a diamond-shaped blade seat and a support assembly;

[0006] Diamond-shaped knife seat: the edge is provided with a knife edge;

[0007] Support assembly: comprises a mounting hole, a connecting strip and a supporting ring. A mounting hole is opened in the middle of the diamond-shaped knife seat, a supporting ring is arranged inside the mounting hole, evenly distributed connecting strips are fixed on the circumferential surface of the support ring, and all the connecting strips are fixed inside the mounting hole. A storage assembly is arranged on the circumferential surface of the support ring, a vibration damping assembly is installed inside the support ring, and two corresponding sealing assemblies are installed at the front and rear ends inside the mounting hole, which are connected to the sealing assembly by setting the support assembly.

[0008] Furthermore, the storage component includes a storage annular groove, a guide annular groove, a first guide groove and an oil outlet hole. A storage annular groove is provided in the middle of the circumferential surface of the support ring, and two corresponding guide annular grooves are provided at the upper and lower ends of the circumferential surface of the support ring. The circumferential surface of the support ring is provided with evenly distributed first guide grooves, and the two guide annular grooves are connected to the storage annular groove through the evenly distributed first guide grooves. Evenly distributed oil outlet holes are provided inside the guide annular groove, and maintenance oil is stored by setting up a storage component.

[0009] Furthermore, the vibration damping assembly includes a vibration damping rubber ring and a second guide groove. The vibration damping rubber ring is fixed inside the support ring. The upper and lower ends of the vibration damping rubber ring are provided with evenly distributed second guide grooves. The second guide grooves correspond to the oil outlet holes. By setting the vibration damping assembly, the vibration of the diamond tool holder can be effectively reduced.

[0010] Furthermore, the sealing assembly includes a sealing ring and fixing bolts. Two corresponding sealing rings are arranged at the upper and lower ends of the mounting hole. The storage annular groove is located between the two sealing rings. The two sealing rings are connected to all the connecting strips through evenly distributed fixing bolts. The sealing assembly is arranged to prevent oil leakage.

[0011] Furthermore, injection holes are arranged on the end surface of the sealing ring, and sealing rods are clamped inside the two injection holes, so that the oil enters the interior of the storage annular groove through the injection holes.

[0012] Furthermore, two corresponding vibration-damping grooves are provided at the left and right ends of the diamond-shaped tool holder, and the mounting hole is located between the two vibration-damping grooves. Vibration can be further reduced by providing the vibration-damping grooves.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the cemented carbide blade with vibration reduction function has the following advantages:

[0014] 1. By setting up a vibration reduction component, the vibration reduction rubber ring is connected to the machine tool spindle when practical. After the connection, the vibration reduction rubber ring can effectively reduce the vibration of the diamond tool holder. At the same time, when the diamond tool holder and the blade are cutting, the vibration generated by the spindle is blocked by the vibration reduction groove when it is transmitted to the blade, thereby reducing the resonance between the blade and the workpiece and reducing the blade vibration.

[0015] 2. By setting up a storage component, the oil is injected into the annular storage groove during use. During the rotation of the diamond-shaped tool holder, the oil in the storage annular groove will enter the two guide annular grooves through the evenly distributed first guide grooves, and then flow into all the second guide grooves through the evenly distributed oil outlet holes, and then enter the gap between the vibration-damping rubber ring and the machine tool spindle through the evenly distributed second guide grooves. In this case, the spindle and the vibration-damping rubber ring can be maintained to increase their service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In which: the end surface of the sealing ring 61 is provided with injection holes, the inside of the two injection holes is clamped with the sealing rods 7, and the oil enters the inside of the storage annular groove 41 through the injection holes.
