It can fill gaps, open up the heat channel between the heating part and the heat dissipation part, effectively improve the heat transfer efficiency, and also play the role of insulation, shock absorption, sealing, etc. When the thermal conductive silicone sheet is processed and formed, the waste edges need to be cut off.

[0003] For example, the Chinese patent publication number CN221232715U discloses an adjustable thermally conductive silicone sheet punching device, which relates to the field of thermally conductive silicone sheet processing technology, including a base and a limit assembly, characterized in that: a workbench is installed on the upper surface of the base, the limit assembly is arranged on the upper surface of the workbench, and the limit assembly includes a fixed plate, an annular slide, a slider, a limit platform, a limit groove and a magnetic plate, and the fixed plate is arranged on the upper surface of the workbench, an annular slide is provided on the upper surface of the fixed plate, and a slider is slidably connected to the inner side of the annular slide, and a limit platform is installed on the upper surface of the slider, and the limit platform is an integrally formed iron structure. The adjustable thermally conductive silicone sheet punching device, through the cutting assembly, allows the device to adjust the cutting position of the punching tool according to the length of the thermally conductive silicone sheet, and through the limit assembly, allows the device to conveniently limit the thermally conductive silicone sheet to be cut to prevent it from shifting during cutting;

[0004] During actual use of the technical solution recorded in this proposal, when punching the thermal silicone sheet, the downward impact force is too great, causing a collision between the punching tool and the workbench, causing damage to the blade of the punching tool and affecting the service life of the punching tool. At the same time, during actual use of this solution, it is not convenient to measure the moving distance of the punching tool, resulting in reduced punching accuracy. Utility Model Content

[0005] In order to solve the above technical problems, the embodiment of the present invention provides an adjustable thermal conductive silicone sheet punching device, which is specifically implemented through the following technical solutions:

[0006] The cam is secured to the base with a pair of slots that are adapted to move relative to the base so that the cam can move relative to the base when the base is in a free-standing position.

[0007] Furthermore, a pair of mounting plates are installed inside the cavities, a pair of fixed plates are installed on both sides of the upper ends of the mounting plates away from the center, a moving rod is installed between the pair of fixed plates, and a pair of moving blocks are slidably connected to the outside of the moving rod.

[0010] The beneficial effect of adopting the above further solution is that the damping rod is hinged to the movable block, the damping rod is hinged to the connecting seat, and the connecting seat is connected to the buffer plate. When the buffer plate is pressed down, the damping rod will drive a pair of movable blocks to move toward the two ends of the movable rod.

[0011] Furthermore, springs are sleeved on both ends of the moving rod, one end of the spring is connected to one side of the outer wall of the moving block, and the end of the spring away from the moving block is connected to one side of the outer wall of the fixed plate.

[0012] The beneficial effect of adopting the above further solution is that, by providing a spring, when the buffer plate contacts the cutter, the cutter will be buffered by the cooperation of the spring and the damping rod.

[0013] Furthermore, a fitting seat is embedded in the inner center of the base, a circular groove is opened in the inner center of the fitting seat, the bottom end of the circular groove is connected to an electrostatic suction cup, and the upper end of the electrostatic suction cup is provided with conductive ceramics.

[0014] The beneficial effect of adopting the above-mentioned further scheme is that by setting up a fitting seat, it is convenient to place the thermal conductive silicone sheet to be punched on the fitting seat. Since there are wire holes on one side of the fitting seat and the base, the wires of the electrostatic suction cup inside the fitting seat are conveniently connected to the controller through the wire holes, so that the user can apply voltage to the electrostatic suction cup through the controller. The charge moves and concentrates on the conductive ceramic, so that the thermal conductive silicone sheet to be punched is adsorbed together with the conductive ceramic to fix the thermal conductive silicone sheet.

[0015] Furthermore, the lifting seat is internally rotatably connected to a bidirectional screw rod, both ends of which are threadedly connected to a moving seat, and one side of the outer wall of a pair of opposite sliders is respectively connected to both sides of the outer wall of one of the moving seats.

[0017] Furthermore, a motor is installed on one side of the outer wall of the lifting seat, and the output end of the motor is transmission-connected to the bidirectional screw through a coupling.

[0018] The beneficial effect of adopting the above further solution is that by providing a motor, when the motor is started, it is easy to drive the bidirectional screw rod to rotate.

[0019] Furthermore, mounting grooves are provided inside the two pairs of support plates, and sliding rods are installed between the inner walls of several mounting grooves. One end of several sliding rods passes through the lifting seat and extends to the outside, and are slidably connected to the lifting seat.

[0020] The beneficial effect of adopting the above further solution is that, by providing the installation groove, it is easy to install the slide rod, and by providing the slide rod, the lifting seat is more stable during the process of moving up and down.

[0021] The beneficial effects of the present invention are as follows: the present invention provides an adjustable thermally conductive silicone sheet punching and cutting device through the above design. The adjustable thermally conductive silicone sheet punching and cutting device is convenient for adjusting the distance between a pair of cutters according to the size of the thermally conductive silicone sheet to be punched out as needed by setting a first slide groove and a slider, thereby realizing adjustment of the position of a pair of cutters. By setting a scale line, it is convenient to measure the moving distance of the cutters. By setting a hydraulic cylinder, it is convenient to realize the up and down movement of the lifting seat when it is working, so that a pair of cutters can punch and cut the thermally conductive silicone sheet. When the cutters are pressed down, The thermally conductive silicone sheet is punched and cut. When the cutter cuts the bottom of the thermally conductive silicone sheet, it will contact the upper end surface of the buffer plate. The pressure of the cutter will drive the buffer plate to press down. The downward pressure of the buffer plate will drive a pair of moving blocks to move toward the two ends of the moving rod under the action of the damping rod, and squeeze the spring, so that the cutter is buffered under the action of the spring and the damping rod, thereby avoiding the impact force of the cutter pressing down being too large, resulting in a collision between the cutter and the buffer plate embedded in the base, causing damage to the cutter. When the punching is completed, the cutter rises and the buffer plate rises with the cutter under the elastic force of the spring. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Example 3

[0036] Reference Figure 1-Figure 5As shown, the internal rotation of the lifting seat 1006 is connected to a bidirectional screw rod 1011, and both ends of the bidirectional screw rod 1011 are threadedly connected to a moving seat 1012. One side of the outer wall of a pair of opposite sliders 1008 is connected to both sides of the outer wall of one of the moving seats 1012.

[0037] Specifically, the working principle of the adjustable thermally conductive silicone sheet punching device is as follows: when in use, the thermally conductive silicone sheet to be punched is placed on the fitting seat 2012, and the user applies voltage to the electrostatic suction cup 2013 through the controller.

When the buffer plate 2004 is pressed down, it drives a pair of moving blocks 2008 to move toward the two ends of the moving rod 2007 under the action of the damping rod 2009 and squeezes the spring 2011, so that the cutter 1009 is buffered under the action of the spring 2011 and the damping rod 2009.
