Technical Field
[0001] The utility model relates to the technical field of heat sink processing equipment, in particular to a heat sink processing cutting equipment. Background Art
[0002] A heat sink is a device that dissipates heat from heat-prone electronic components in electrical appliances. Currently, most of the heat sinks commonly seen on the market are used to dissipate heat for the transformer as a whole. A large amount of heat is generated during the operation of the transformer, and the cooling effect is achieved through the sheet heat sink. Currently, most of the sheet heat sinks used in transformers are cut from cold-rolled thin plates, and the existing cutting equipment for heat sink processing can basically meet daily use needs, but there are still some shortcomings that need to be improved.
[0003] Most of the heat sink cutting equipment widely used in the market adopts a cutting machine to cut the placed heat sink sheets. However, in actual use, when cutting a multi-layer sheet, the ends of the sheet are easily lifted up by the downward pressure of the cutting machine, causing the fixed position of the sheet to change, which easily leads to changes in the size of the cut heat sink, resulting in a reduction in the yield of the heat sink. For this reason, we propose a heat sink cutting equipment to solve the above problem. Utility Model Content

[0008] As a further preferred embodiment of the present technical solution, an anti-slip pad is glued to the outer wall of the bottom end of the pressing plate.
[0009] As a further preferred embodiment of the present technical solution, a plurality of groups of anti-slip grooves are provided on the outside of the throttle at equal intervals along the axis of the throttle.

[0011] As a further preferred embodiment of the present technical solution, the angle between the transverse push plate and the positioning plate is ninety degrees.
[0012] The utility model provides a cutting device for heat sink processing, which has the following beneficial effects:
[0013] 1. The utility model has fixed positioning plates and side plates that can be moved laterally on both sides of the cutting table. When the heat dissipation sheet needs to be cut, it can be placed on the cutting table and the handle is turned to allow the threaded rod to drive the side plates to move laterally under the action of the thread, so that the side plates push the sheet to the positioning plates to fix the two sides of the sheet, and then a lifting and lowering pressure plate installed on the top of the positioning plate is used to allow the return springs outside the two groups of guide slide rods to apply downward elastic force to the wire sliding sleeves, so that the two groups of wire sliding sleeves drive the pressure plate to move above the sheet, and the end of the sheet is pressed down and fixed, so that the heat dissipation sheet can be stably fixed on the cutting table. When the cutting machine cuts it, it can effectively prevent the sheet from being displaced, thereby improving the yield rate of the heat sink.
[0014] 2. The utility model installs a movable horizontal push plate at the front end of the positioning plate. When the cutting machine completes cutting the heat dissipation thin plate on the cutting table, the horizontal handle can be lifted upwards to allow the pressure plate to release the fixation of the cut heat sink first, and then the push handle at the end of the movable rod is pushed inwards, so that the movable rod drives the horizontal push plate to move backward along the fixed sleeve, and the horizontal push plate pushes the heat sink under the pressure plate, so that the cut heat sink falls into the collection net for cooling, thereby quickly discharging the heat sink under the pressure plate, facilitating the rapid subsequent cutting operation, and improving the convenience of the device when used.
