Technical Field

[0001] The invention relates to the technical field of fin processing, and in particular to a stamping forming device for fin processing. Background Art

[0002] Heat exchange tubes are a commonly used heat exchange element, usually made of copper, aluminum or copper-aluminum alloy. Heat exchange tubes are generally composed of a tube body and multiple fins located on the side of the tube body. The fins can increase the heat exchange area and thus improve the heat exchange efficiency, so the fins are also called heat dissipation fins. Heat dissipation fins are important components in radiators and play a major role in heat dissipation in radiators. Punching is required in the production of heat dissipation fins, which is mostly completed using stamping forming technology. Existing stamping devices can only perform a single type of stamping action and cannot adjust the stamping type at will. There are certain limitations.

The sensing device 9 adopts a convex structure design and is located on one side of the upper bin 2. It can not only ensure the position of the fins, but also leave enough space for the moving block 7 to be retained, so as to control the movement of the fins. A telescopic baffle 10 is arranged on the top of the main body 1. The telescopic baffle 10 includes a spring and a baffle. The top of the baffle adopts an inclined structure design, which can play a certain blocking role on the fins, and can also shrink after being forced to facilitate their passage.

A lifting plate 13 is fixedly installed on the top of the lifting bracket 12. There are four groups of second screw rods 11, and they are all L-shaped structures and symmetrically distributed, so as to control the lifting. The lowering plate 13 is stably supported, a third screw 14 is rotatably connected in the upper bin 2, and a shaping frame 15 is connected to the outside of the third screw 14 through a thread. One side of the shaping frame 15 adopts an inclined structure design, and the inclined surface is used to contact the fin to complete the shaping. A fourth screw 16 is rotatably connected in the frame 5, and a mold frame 17 is connected to the outside of the fourth screw 16 through a thread. A plurality of stamping molds 18 are slidably connected in the mold frame 17. A fixed frame 19 is fixedly installed in the frame 5, and a lifting rod 20 is slidably connected to the top of the fixed frame 19, and a compression spring 21 is connected between the fixed frame 19 and the lifting rod 20, and a mounting frame 22 is fixedly installed at the bottom of the lifting rod 20.
