Embodiment
[0027] See figure 1 , in order to facilitate the public’s understanding, the applicant shows a piston column 1 as the structural system of the stamping machine in the figure. According to common knowledge, if the stamping machine is a hydraulic machine, the piston column 1 is essentially the oil cylinder of the hydraulic cylinder of the hydraulic press. Column, if the stamping machine is a pneumatic stamping machine, then the piston column 1 is essentially the cylinder column of the cylinder, and the latter is selected in this embodiment.
[0028] Provided is an upper die mechanism 2 for connecting with the piston rod 1 of the aforementioned punching machine in the state of use and an upper die mechanism 2 for setting on the workbench of the punching machine and corresponding to the lower part of the upper die mechanism 2 in the state of use. Lower mold mechanism 3. The aforementioned upper mold mechanism 2 includes an upper mold frame 21, an upper mold pressing plate 22, an ...

A device for the non-riveting connection of cooling fins belongs to the technical field of equipment for machining transformer heat sinks. The device comprises an upper die mechanism and a lower die mechanism, wherein the upper die mechanism comprises an upper die carrier, an upper die press plate, upper dies and upper die press plate-restoring springs, the upper die carrier is connected with a piston rod, the upper die press plate is connected with the upper die carrier, the upper dies are connected with the upper die carrier, the upper ends of the upper die press plate-restoring springs are supported on one side of the upper die carrier, and the lower ends of the upper die press plate-restoring springs are supported on one side of the upper die press plate; the lower die mechanism comprises a lower die carrier, a lower die press plate, lower dies and lower die press plate-restoring springs, the lower die carrier is arranged on the working table of a punch, the lower die press plate is connected with the lower die carrier, a lower-cooling-fin pressing cavity is formed along the length direction of the lower die press plate, the lower dies are connected with the lower die carrier, the upper ends of the lower die press plate-restoring springs are supported on one side of the lower die press plate, the lower ends of the lower die press plate-restoring springs are supported on one side of the lower die carrier, and the upper dies and the lower dies cooperate with each other. The connecting effect is excellent; the cost is reduced, and the thermal deformation of cooling fins is prevented; the service life is ensured; the efficiency of operation is high.
Description
technical field [0001] The invention belongs to the technical field of processing equipment for transformer radiators, and in particular relates to a device for non-riveting connection of radiator fins. Background technique [0002] The above-mentioned concept of non-riveted connection of the heat sink means that there is no need to use rivets, electrodes or other similar means to combine the upper and lower plates of the heat sink made of metal. [0003] As known in the industry, in order to make the oil-immersed transformer operate normally, it is usually necessary to install a fin radiator on the side and / or upper part of the transformer, and the fin radiator plays the role of cooling the transformer, and the radiator is composed of It is composed of a plurality of cooling fins, which can be fully understood by reading and not limited to the patented technical solutions listed below and disclosed by Chinese patent documents. Such as CN201084519Y (transformer radiator), C...
