[0033] The upper die base 2 is connected to the lower die base 1 by a lifting rod 3 connected to a motor, and an adjustment groove 21 is provided on the bottom surface;
[0034] The stamping die 4 is detachably mounted on the lower die base 1, and a positioning groove is arranged inside. The radiator part 10 is placed in the positioning groove. A stamping cavity 42 is arranged on the bottom surface of the positioning groove. An upper positioning piece 9 for auxiliary positioning is arranged on the top of the radiator part 10;
[0035] The stamping mechanism includes a slider 5 slidably connected to the adjustment slot 21 by the drive of a driving mechanism 22, a lifting column 6 connected to the bottom of the slider 5 by a motor, and a stamping head 7 detachably connected to the bottom of the lifting column 6. The side of the stamping head 7 is elastically slidably arranged to abut and position a positioning block 8 around the stamping area of the radiator part 10.
[0036] The adjustment slot 21 is an I-shaped adjustment slot, the driving mechanism 22 is a linear motor, the slider 5 includes a T-shaped limit block 52 and a slider body 51, the limit block 52 is slidably connected to the top of the adjustment slot 21, and the side of the slider body 51 is connected and driven by the driving mechanism 22. The motor used to drive the lifting rod 3 and the lifting column 6 in the punching device and the driving mechanism 22 are connected to the device external controller and controlled uniformly.
[0037] A mounting block 61 is provided at the bottom of the lifting column 6 and is plugged into the top of the punch head 7. A clamping block 62 is circumferentially provided on the outer wall of the mounting block 61. The clamping block 62 is clamped in the clamping groove 71 at the top of the punch head 7, so that the punch head 7 can be easily disassembled and replaced to adapt to the stamping operation of different radiator part structures.
[0038] A movable groove 73 is arranged on the side of the punching head 7, and a lifting block 81 is slidably connected in the movable groove 73. An elastic member 74 is arranged between the bottom surface of the movable groove 73 and the bottom surface of the lifting block 81. The lifting block 81 is fixed on the side surface of the positioning block 8. The positioning block slides elastically on the side surface of the punching head, so that after the punching head punches the part and moves up to disengage from the punching of the part, the elastic member rebounds and forms an extrusion on the edge of the stamping area on the top surface of the radiator part, thereby avoiding the problem of warping and deformation caused by the friction between the punching head and the punching edge of the radiator part during the upward movement of the punching head.
[0039] The bottom surface of the punch head 7 is provided with an arc-shaped punching surface 72 , and the arc-shaped punching surface 72 matches the bottom surface of the punching cavity 42 .
[0040] A first mounting side edge 41 is arranged outside the stamping die 4 and is fixed to the lower die base 1 by bolts, so that the stamping die 4 is easy to disassemble and replace to adapt to the positioning and stamping operations of different radiator part structures.
[0041] The upper positioning member 9 includes an inner limit ring and a second mounting side edge.

The second mounting side edge is fixed to the stamping die 4 by bolts. The inner and outer sides of the cover-shaped radiator part are abutted against each other through the stamping die positioning groove and the upper positioning member to assist in positioning, thereby avoiding displacement of the part during stamping.
[0042] The working principle of the radiator part stamping device with an auxiliary positioning mechanism in this embodiment includes: the stamping device can stamp and shape the heat dissipation port on the radiator shell. Of course, by replacing the stamping die 4 and the stamping head 7, stamping and shaping operations of other structures can be performed. When in use, the motor is operated to make the lifting rod 3 drive the upper die base 2 to lift up. Based on the size of the radiator part, the corresponding stamping die 4 is installed on the top surface of the lower die base 1 by bolting with the first mounting side edge 41, and the radiator part 10 is placed in the positioning groove of the stamping die 4, and the stamping area corresponds to the stamping cavity 42, and then the upper positioning piece 9 is abutted against the inner side of the radiator part 10, and the radiator part 10 is auxiliaryly positioned with the stamping die 4. Finally, the upper positioning piece 9 and the stamping die 4 are fixed by bolts; select a suitable stamping head 7 according to the radiator part 10, and install the positioning block 8 in the movable groove 73 of the stamping head 7, and then the stamping head 7 is clamped and installed on the mounting block 61 of the lifting column 6, and the motor is operated to move the lifting rod 3 downward, driving the upper die base 2 and the top surface of the stamping die 4 to be closed, so that the part can be stamped. The slider 5 is driven to move by the driving mechanism 22 of the linear motor so that the punching head 7 is located directly above the punching cavity 42. The motor drives the lifting column 6 to move downward, so that the punching head 7 moves downward to perform a punching operation on the radiator part, and cooperates with the punching cavity 42 to shape the radiator part. At this time, the positioning block 8 is squeezed by the edge of the punching area on the top surface of the radiator part 10, and the lifting block 81 moves up to the top of the movable groove 73 and is fixed, and the edge of the punching area on the top surface of the radiator part 10 is squeezed and positioned, and the elastic member 74 is stretched; when the stamping area of the radiator part 10 is shaped, the lifting column 6 drives the punching head 7 to move up from the punching hole of the radiator part 10, and the elastic member 74 rebounds to squeeze the edge of the stamping area on the top surface of the radiator part 10, so as to avoid the problem of warping and deformation caused by the friction between the punching head 7 and the punching edge of the radiator part 10 during the upward movement process, thereby realizing the function of auxiliary stamping and shaping. The driving mechanism 22 moves the slider 5 to achieve accurate alignment of the punch head 7 with other punching cavities 42, and the above steps are repeated to perform the overall punching operation of the radiator part 10. The alignment of the punch head 7 with the punching cavity 42 is accurately controlled by the controller, which is a common technical means in the field of automation devices.
[0043] In summary, due to the adoption of the above technical solution, the heat sink part stamping device with an auxiliary positioning mechanism in this embodiment has the following beneficial effects compared with the prior art:
[0044] The present stamping device uses the positioning groove of the stamping die in conjunction with the upper positioning piece to perform auxiliary positioning of the inner and outer sides of the cover-shaped radiator parts, thereby avoiding displacement of the parts during stamping.
