Description

Technical Field

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

[0002] A heat sink is a device that dissipates heat from heat-prone electronic components in electrical appliances. It is usually made of aluminum alloy, brass or bronze in the form of plates, sheets, or multiple sheets. For example, a CPU in a computer requires a fairly large heat sink, as do power tubes, line tubes, and amplifier tubes in a TV. Generally, a heat sink should be coated with a layer of thermal conductive silicone grease on the contact surface between the electronic component and the heat sink during use, so that the heat generated by the component can be more effectively transferred to the heat sink, and then dissipated to the surrounding air through the heat sink. After the heat sink is produced, it needs to be cut and processed according to certain sizes according to demand.

[0003] The common quantitative cutting device used for heat sink processing has the function of clamping and positioning the heat sink when in use. However, every time the heat sink needs to change direction, it needs to be released first, and then rotated and positioned again before cutting can be performed. It cannot be performed synchronously, which greatly reduces work efficiency.

[0004] Therefore, for the above-mentioned quantitative cutting device for processing heat sinks, when changing the direction of the heat sink, it is necessary to release the positioning and then re-position and cut, which has a low efficiency problem and needs to be solved urgently to improve the use scenario of the quantitative cutting device for processing heat sinks.
