DETAILED DESCRIPTION

[0013] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0014] like Figure 1~2 As shown, a metal can stamping forming device includes a stamping frame 24, a movable stamping lower die is arranged on the top of the stamping frame 24, a stamping upper die 25 is arranged above the stamping lower die, and the stamping upper die 25 is installed at the bottom of a hydraulic mechanism 26.

[0015] In this embodiment, the stamping lower die includes a first outer die 27 and a second outer die 28, and the first outer die 27 and the second outer die 28 are detachably attached together. A stamping inner die 39 is arranged inside the first outer die 27, and the stamping inner die 39 is used to cover the metal can.

[0016] In this embodiment, a slide rail 29 is disposed on the stamping frame 24 , the first outer mold 27 is fixed on the top surface of the slide rail 29 , and the first outer mold 27 is slidably disposed on the top surface of the slide rail 29 .

[0017] In this embodiment, a push frame 30 is provided on the outer end surface of the second outer mold 28, and a clamping rod 31 is installed on both sides of the push frame 30 respectively. The other end of the clamping rod 31 is fixed on a clamping frame 32, and a lower mold cylinder 33 for driving the clamping frame 32 to move is provided on the stamping frame 24. A guide block 34 passed by the clamping rod 31 is installed on the side of the stamping frame 24, and a guide hole is opened on the guide block 34.

[0018] In this embodiment, a locking cylinder 35 is provided at the top of the push rack 30, and a rotating rod 36 is rotatably installed on the piston end of the locking cylinder 35. The other end of the rotating rod 36 is fixed on an eccentric wheel 37. The eccentric wheel 37 is sleeved on a rotating shaft 38. The rotating shaft 38 is located at the top of the push rack 30 on the outer end surface of the second outer mold 28.

[0019] Working principle: After placing the metal can on the inner mold 39, the lower mold cylinder 33 pushes the clamping frame 32 backward, the clamping frame 32 drives the clamping rod 31 to move, the clamping rod 31 drives the push frame 30 to move, and the push frame 30 drives the second outer mold 28 to clamp the first outer mold 27. After the first outer mold 27 and the second outer mold 28 are clamped, the locking cylinder 35 drives the rotating rod 36 to rotate, and the rotating rod 35 drives the eccentric wheel 37 to rotate. After the eccentric wheel 37 rotates, the second outer mold 28 and the first outer mold 27 are more closed, and then the stamping upper mold is pressed down and the stamping lower mold is clamped as a whole, so that the metal can is stamped and formed.

[0020] The above is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any simple modification, equalization change and modification made to the above embodiment by any technician familiar with the field according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall fall within the scope of the present invention.
