Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with specific embodiments.

[0018] as attached figure 1 As shown, the die device of the present invention is divided into five parts, including a die handle 1, a nut 2, a large die head 3, a small die head 4, and an ejector 5; The screw rod of the small die head 4 penetrates into the center hole of the large die head 3, and is tightened and fixed by two nuts 2, and the ejector 5 is assembled between the large die head 3 and the small die head 4, relying on its own elastic force It is fixed to the inside of the die head, and finally the large die head 3 and the die handle 1 are assembled by threaded connection.

[0019] Each part of the die device can be made of suitable materials according to the needs. In particular, the materials of each structure of the die device in this embodiment are: die handle 1, material 45 steel, HRC35-38; M6 nut 2; ejector 5. The material is nitrile rubber, the ejector ...

Abstract

The invention relates to a thin-walled annular aluminum foil forming method and a blanking die device. According to the thin-walled annular aluminum foil forming method, a punching machine is adoptedto machine and form thin-walled annular aluminum foil, a fabroil is put on a workbench of the punching machine, the upper part and the lower part of the aluminum foil are covered and protected throughthin powder paper, and after the aluminum foil is protected, the aluminum foil is laid on the fabroil to be blanked; and after blanking is completed, shape correcting is carried out, to avoid scratching and pits during shape correcting, the upper face and the lower face of the annular aluminum foil are covered and protected through the thin powder paper, the thin-walled annular aluminum foil is put on the smooth tempered glass surface and is leveled. The blanking die device comprises a blanking die handle, a large blanking die head, a small blanking die head and an elastic jacking device. Aninner and outer blanking die head combined mode is adopted, the small blanking die head is sleeved with the large blanking die head, and the annular elastic jacking device is arranged in the middle. According to the thin-walled annular aluminum foil forming method and the blanking die device, the problem that as the aluminum foil is very thin, difficulty of annular part machining is very large issolved. The consistency of sizes of inner circles and outer circles of annular aluminum foil in batch machining is guaranteed, the part machining precision is high, edges are very tidy, and no burr exists. The die is low in machining cost, and low-cost popularization can be achieved.

Description

technical field [0001] The invention relates to a forming method of aluminum foil, in particular to a forming method of thin-walled annular aluminum foil. Background technique [0002] At present, the thickness of aluminum foil at home and abroad is generally 0.02mm to 0.15mm, and the surface processing quality requirements are very high. There are no stretched and torn burrs on the edges, and no scratches, indentations, wrinkles and other defects on the surface. At present, there is no advanced process for processing circular aluminum foil parts at home and abroad. The processing methods of round aluminum foil generally include manual cutting, manual punching with a die, and punching. For processing annular aluminum foil, there is no advanced process for processing similar parts at home and abroad. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a thin-wall annular aluminum foil forming method to solve the pro...
