Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a cutting device for a metal product heat sink. Background Art

[0002] A metal heat sink is a heat dissipation device made of metal materials. Its main function is to accelerate the transfer and dissipation of heat to keep the operating temperature of an electronic device or system within a reasonable range. The heat sink is usually made of metals with good thermal conductivity, such as aluminum or copper, because these materials can conduct and dissipate heat more effectively, and the working principle of the heat sink is mainly based on heat conduction, convection and radiation. However, before the metal heat sink is used, it needs to be cut to the required size by a cutting device. The existing cutting devices are mostly one-way assembled for cutting when used. Since the heat sink requires different sizes and shapes during production, the inconveniently adjusted cutting device may cause inaccurate cutting and errors, thereby affecting the appearance quality and performance of the heat sink. Therefore, we propose a cutting device for metal heat sinks to solve the above-mentioned problems. Utility Model Content

According to the position where the heat sink of the metal product is fixed, the rectangular slider drives the rectangular telescopic column to slide along the sliding groove and connect with the load-bearing platform and move to a suitable position through the drive of the driver. Then, the U-shaped telescopic sleeve moves to a suitable height along the rectangular telescopic column through the drive of the first cylinder.

[0012] Beneficial effects of the utility model:

[0013] 1. In the past, most cutting devices were assembled in one direction for cutting. Since the heat sinks require different sizes and shapes during production, the inconveniently adjusted cutting device may cause inaccurate cutting and errors, thereby affecting the appearance quality and performance of the heat sink. The difference is that the bottom plate is first driven to move to the required position by the pulley, and then the metal heat sink is placed on the operating table. When the metal heat sink is placed, according to the position and size of the metal heat sink, the strip slider drives the U-shaped frame to slide along the strip groove and connect with the load-bearing platform through the drive of the driver, and moves to a suitable position. Then, through the drive of the driver, the sliding block drives the square telescopic sleeve to slide along the slide groove and connect with the U-shaped frame to move to a suitable position. Then, through the drive of the second cylinder, the square telescopic column drives the fixing plate to move downward along the square telescopic sleeve to press and fix the metal heat sink, so as to avoid the movement of the metal heat sink during the cutting process, which causes cutting errors and improves the appearance quality and performance of the metal heat sink.

[0014] 2. Pour water from the water inlet pipe into the water supply tank. When the cutting disc starts cutting, the water source enters the water outlet pipe from the water supply tank through the drive of the water pump and sprays on the cutting disc. When the cutting disc is rotating and cutting at high speed, a lot of heat will be generated. Spraying water on it can reduce the temperature accordingly to avoid heat accumulation affecting the service life of the cutting disc. At the same time, the debris generated by the metal heat sink during cutting is cleaned up, so that it reaches the bottom of the rectangular groove along the cutting groove, and then passes through the water outlet hole and enters the receiving box through the connecting water pipe to avoid a large amount of debris accumulation and affect the accuracy of metal heat sink cutting. When the receiving box is full, the used water source and debris flow out through the outlet pipe by loosening the sealing cover. BRIEF DESCRIPTION OF THE DRAWINGS
