Description

Double skiving processing device and heat sink processing method using it {DOUBLE SKIVING PROCESSING DEVICE AND HEAT SINK PROCESSING METHOD USING THE SAME}

The present invention relates to a double skiving processing apparatus and a heat sink processing method using the same.

A heat sink is a type of heat exchanger and has a material and structure specialized for heat conduction and radiation, taking heat from a heat-generating system and discharging it to the surroundings. The heat sink is made with a design that maximizes the surface area for effective heat dissipation, and has a plurality of heat dissipation fins for this purpose.

Since the heat sink must emit as much heat as possible over a large surface area, it can be made of a material that is lightweight and has excellent thermal conductivity. For this, aluminum alloy is the most widely used heat sink. Although copper has better thermal conductivity, it is much heavier and more expensive than aluminum, so it is not used much. Sometimes, the part in direct contact with the heat-generating component is made of copper, and the heat sink/radiation fin surrounding it is made of aluminum alloy.

Recently, high-integrated circuits are used in a limited space of electrical and electronic devices used in various ways according to industrial development, and this uses electrical energy, and the remaining energy is converted into a heat source, generating a lot of heat. Due to such excessive heat generation, the performance of the electric/electronic device may be extremely degraded or may cause a failure. Accordingly, improvement in performance of a heat sink that dissipates heat to the outside has emerged as a problem.

However, in the case of using only a single cutting edge when manufacturing a heat sink, the machine tool in the conventional skiving facility can process only a simple straight radiating fin, making it difficult to increase the surface area without improving the facility.

The double skiving processing device 10 includes the first cutting edge 200 and the second cutting edge 300 having different shapes, and can make shapes that are difficult to process at the time of heatsink processing with uniform quality.

For example, the double skiving processing apparatus 10 cuts the heat radiation fin protrusions 31 on the surface of the heat sink base 20 using the second cutting edge 300, and then uses the first cutting edge 200 to cut the heat radiation fins. (30) can be cut (see Figs. 2 and 3). Through this process, it is possible to process the radiating fin 30 provided with the radiating fin protrusion 31 having a larger surface area than the existing linear radiating fin 30 .

The double skiving processing device 10 also enables the second cutting edge 300 to reciprocate, so that the first cutting edge 200 and the second cutting edge 300 can be selectively utilized as needed. In addition, by automating the reciprocating movement of the second cutting edge 300, it is possible to shorten the machining time and promote convenience for the operator.

Here, those with ordinary knowledge in the technical field related to this embodiment know that other general-purpose components may be further included in the double skiving processing apparatus 10 in addition to the components shown in FIGS. 1 to 9 I can understand.

The frame 100 may serve as a body of a double skiving processing device 10 to which a first cutting blade 200, a second cutting blade moving unit 500, and a fixing unit 400 are coupled. The frame 100 may have a rectangular box shape with a flat lower surface where the first cutting blade 200 and the second cutting blade moving unit 500 are coupled. The frame 100 may include a plurality of coupling holes (not shown) formed on the lower surface to allow the first cutting blade 200 and the second cutting blade moving unit 500 to be coupled.

The frame 100 is made of a steel material having sufficient rigidity not to be damaged even in shock and vibration caused by repeated cutting operations using the first cutting edge 200 and the second cutting edge 300. It can be. However, the shape and material of the frame 100 is not limited thereto and may have various shapes and materials.

The frame 100 and the first cutting blade 200 may be coupled by fastening the fastening module (b) to the first coupling hole 210 of the first cutting blade 200 and the lower surface of the frame 100 .

The protruding portion of the first cutting edge 200 may be used to form the radiating fin 30 of the heat sink by forming the first inclined surface 220 forming the first inclined angle a1. The first inclined surface 220 of the first cutting edge 200 may be a flat inclined surface maintaining a constant first inclined angle a1 in order to form the repeating heat dissipation fin 30 at regular intervals. The first inclination angle a1 of the first cutting edge 200 may be changed according to the required shape and thickness of the heat dissipation fin 30 .

For this reason, friction and vibration may be reduced during cutting using the second cutting blade 300 .

The second cutting edge 300 is cut to form the radiation fin protrusion 31 of the heat sink, and cemented carbide having greater strength and rigidity than aluminum, copper, magnesium, etc. used in the heat sink may be used. can However, the material of the second cutting blade 300 is not limited thereto and various materials may be used.

That is, the linear guide 520 slides by receiving power from the actuator 510 coupled to one end, and accordingly, the second cutting edge 300 coupled to the other end can reciprocate along the first direction d1. .

The linear guide 520 may have a column shape extending in a straight line along the first direction d1 in which the second cutting edge 300 moves. Since the linear guide 520 should not be deformed despite the load and applied stress of the second cutting edge 300, it may be made of steel or reinforced plastic material having sufficient rigidity.

In the first moving step (S100), the second cutting blade 300 may be moved forward to the fixed position S using the second cutting blade moving unit 500 (see FIG. 7). That is, in the first moving step (S100), the actuator 510 may be operated to move the second cutting edge 300 coupled to the linear guide 520 forward to the fixed position S.

In the fixing step (S200), the position of the second cutting edge 300 may be fixed using the fixing part 400 (see FIG. 7). That is, in the fixing step (S200), the driving module 410 may be operated to lower the stopper 420 downward along the second direction d2. Accordingly, the position of the second cutting edge 300 may be fixed by the stopper 420 .

In the first cutting process ( S300 ), the heat sink may be cut using the second cutting blade 300 (see FIG. 2 ). At this time, the second cutting edge 300 may be used to make a heat radiation fin protrusion 31 for increasing the surface area on the surface of the heat radiation fin 30 . Since the second inclination angle (a2) of the second cutting edge 300 is greater than the first inclination angle (a1) of the first cutting edge 200, as shown in FIG. It can be easy to do.

In the fixing releasing step ( S400 ), the fixing of the second cutting edge 300 of the fixing part 400 may be released (see FIG. 8 ). That is, in the unfixing step ( S400 ), the driving module 410 may be operated to raise the stopper 420 upward along the second direction d2 .
