Problems solved by technology
[0003] However, this device is only suitable for the bending operation of plates with uniform thickness and low requirements for the accuracy of the bending angle. The heat conduction sheet with an insulating layer or other protective layer added to the surface, the punch of the device directly collides with the heat conduction sheet Bending in the same way will cause deviations in the punched angle and size of both sides of the heat conduction sheet, thus failing to meet the use requirements of the heat conduction sheet

The invention relates to the technical field of bending devices, and provides a rotary bending tool for a heat-conducting sheet, comprising: a support base, on which a plurality of positioning pins are arranged; The pressing component is movably provided with a pressing plate; the bending component is provided with a bending block, which is rotatably arranged on both sides of the pressing plate and can be in the first position on the pressing component and the second position; when the extrusion plate drives the bending block to switch from the first position to the second position, the bending block can drive the heat-conducting sheet on the support base to perform the bending operation. Compared with the prior art, the advantage of the present invention is that the bending block can drive the parts that need to be bent on both sides of the heat-conducting sheet to perform gradual bending during the turning process, and prevent the two parts of the heat-conducting sheet that need to be bent during bending. Unnecessary dimensional changes occur on the sides, and finally ensure the bending size of the thermal conductive sheet and the punched angle on both sides of the thermal conductive sheet.
Description
technical field [0001] The invention relates to the technical field of bending devices, in particular to a rotary bending tool used for a heat-conducting sheet. Background technique [0002] The thermal conductive sheet has the effect of heat conduction and insulation. It is used between the heating device and the heat sink or the metal base. It usually needs to attach a layer of protective film to it in the production process and then bend it to make it with other There are many bending devices in the traditional process, such as the Chinese invention patent (application publication number: CN 110722031A), which has been in the public state, which discloses a bending device, including a support assembly, a rotating plate and a convex mold. There are two rotating plates, and the two rotating plates are arranged side by side in the horizontal direction. The two rotating plates are respectively rotatably connected to the support assembly, and can rotate from a horizontal stat...
