DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1: Please refer to Figure 1-4 The utility model provides a technical solution: a punching device of a can body machine, comprising a can body machine mounting frame 100; two servo motors 200 are fixedly mounted on the inner wall of the can body machine mounting frame 100, and a lifting and stamping structure is mounted on the two servo motors 200; two side slide rails 300 are symmetrically fixedly mounted on the inner wall of the can body machine mounting frame 100, and a guide structure is mounted on the two side slide rails 300; two cams 400 are mounted on the lifting and stamping structure, and detection structures are mounted on the two cams 400. The cooperation of the lifting and stamping structure, the guide structure and the detection structure can realize automatic stamping of the can body, and detect the operation of the lifting and stamping structure to ensure the continuity and stability of the production process.

[0020] Further, the lifting and stamping structure includes two reducers 201, the two reducers 201 are fixedly mounted on the inner wall of the can body machine mounting frame 100, the output ends of the two servo motors 200 are respectively connected to the input shafts of the two reducers 201, one side of the two reducers 201 is fixedly mounted with a first bearing seat 202, the output shafts of the two reducers 201 are fixedly mounted with a connecting shaft 203, the two connecting shafts 203 are movably mounted in the two first bearing seats 202, one end of the two connecting shafts 203 is fixedly mounted with a crankshaft 204, the two crankshafts 204 are rotatably mounted with connecting rods 205, and one end of the two connecting rods 205 is threadedly mounted with a movable rod 206. A stamping slider 207 is movably mounted on the two movable rods 206, and a can body machine mold is connected to the two stamping sliders 207. A fixed shaft 208 is fixedly mounted on one end of the two crankshafts 204, and a second bearing seat 209 is movably mounted on the two fixed shafts 208. The two second bearing seats 209 are fixedly mounted on the inner wall of the can body machine mounting frame 100. When the servo motor 200 is turned on, the stamping slider 207 can be reciprocated vertically. When the stamping slider 207 rises, the connected can body machine mold can be driven to rise. At this time, the conveyor belt can be used to move the can body to the bottom of the stamping slider 207 and the mold, and then the stamping slider 207 drives the mold to descend and stamp the can body.

[0021] Furthermore, a movable hole 210 is opened on the inner wall of the stamping slider 207, and the movable rod 206 is movably installed in the movable hole 210. During the reciprocating sliding of the stamping slider 207, the angle between the connecting rod 205 and the movable rod 206 will change. By setting the movable hole 210, the movable rod 206 and the inner wall of the stamping slider 207 can be prevented from being squeezed.

[0022] Furthermore, a crankshaft hole 211 is opened on the connecting rod 205, and the crankshaft 204 is rotatably installed in the crankshaft hole 211. The rotating crankshaft 204 will rotate in the crankshaft hole 211, and can drive the connecting rod 205 to reciprocate vertically by cooperating with the crankshaft hole 211.

[0023] Furthermore, the guiding structure includes an intermediate slide rail 301, which is fixedly mounted on the inner wall of the can body machine mounting frame 100, and guide slide bars 302 are fixedly mounted on both sides of the two stamping slide blocks 207. A first guide slot 303 is provided on one side of the two side slide rails 300, and a second guide slot 304 is provided on both sides of the intermediate slide rail 301. The two guide slide bars 302 on the same side are respectively slidably mounted in the corresponding first guide slot 303 and second guide slot 304. The sliding stamping slide block 207 will drive the guide slide bars 302 on both sides to slide in the corresponding first guide slot 303 and second guide slot 304, respectively, thereby limiting the stamping slide block 207 to only slide vertically, thereby preventing the stamping slide block 207 from offset.

[0024] Furthermore, the detection structure includes two induction magnets 401, and the two induction magnets 401 are fixedly mounted on the cam 400, and the cam 400 is fixedly sleeved on the fixed shaft 208. An L-shaped connecting plate 402 is fixedly mounted on the inner wall of the can body machine mounting frame 100, and two induction components 403 are connected to the L-shaped connecting plate 402. The two induction components 403 correspond to the two induction magnets 401 respectively. During the rotation of the fixed shaft 208, the two induction magnets 401 will be driven to pass under the two induction components 403 respectively, so as to detect the rotation of the cam 400, thereby ensuring the stability of the production process.

[0025] The working principle is as follows: when the servo motor 200 is turned on, its output end can drive the input shaft of the reducer 201 to rotate, so that the output shaft of the reducer 201 rotates and drives the connecting shaft 203 to rotate on the first bearing seat 202. When the connecting shaft 203 rotates, it will drive the crankshaft 204 to rotate, so that the crankshaft 204 drives the fixed shaft 208 to rotate on the second bearing seat 209. By setting the first bearing seat 202 and the second bearing seat 209, the crankshaft 204 can rotate more smoothly. The continuously rotating crankshaft 204 will drive the connecting rod 205 through the cooperation with the crankshaft hole 211. The vertical reciprocating movement enables the connecting rod 205 to drive the stamping slider 207 to slide vertically reciprocatingly through the movable rod 206. When the stamping slider 207 rises, it can drive the connected can body machine mold to rise. At this time, the conveyor belt can be used to move the can body to the bottom of the stamping slider 207 and the mold, and then the stamping slider 207 drives the mold to descend and stamp the can body. During the rotation of the fixed shaft 208, the two induction magnets 401 will be driven to pass under the two induction components 403 respectively. The magnetic field induction and Hall effect principles are used to detect the rotation of the cam 400, thereby ensuring the stability of the production process.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
