Description

Technical Field

[0001] The invention relates to the technical field of can production, and in particular to a stamping device for producing and processing aluminum cans. Background Art

[0002] Can stamping includes the stamping technology for the can body and can cover respectively. In real life, canned beverages are very popular. These cans are generally composed of two parts: the can body and the can cover. The industry calls them two-piece cans. Simply put, the material of the can cover itself is processed to form a rivet, which is riveted to the can body, and a pull ring is riveted on the outer cover, and then formed with appropriate notches. Because the can body and can cover of the can have a large difference in appearance, the stamping process and mold use are different, so most of them use different equipment for cutting, stamping, drawing and other processing processes. The existing Chinese invention patent with announcement number CN116532577A discloses an industrialized can production and production stamping system to solve the problem that the production efficiency is affected by the need for segmented processing such as cutting, stamping and drawing. Based on this patent, it is mainly for the stamping and forming of the can body, and other equipment is also needed to stamp the can cover. The increase of equipment will affect the processing cost and processing efficiency. A Chinese patent discloses a stamping device for the production and processing of aluminum cans (authorization announcement number CN119216489B). The patented technology discloses a stamping device for the production and processing of aluminum cans, including a frame, a plurality of columns installed on the frame, a middle plate fixed on the columns, and a circulating oil supply component and a stamping component installed on the middle plate. The frame includes a bottom plate, a top plate arranged above the bottom plate, and side frames fixed on both sides of the bottom plate and the top plate. A No. 1 aluminum strip transmission component and a No. 2 aluminum strip transmission component are respectively installed on the bottom plate and the top plate. When the stamping component is in progress, it is used for punching and stretching the aluminum strip on the No. 1 aluminum strip transmission component to form a can body; when the stamping component is in return, it is used for punching and stretching the aluminum strip on the No. 2 aluminum strip transmission component to form a can cover; the invention makes full use of the driving force and stroke change generated by the return oil contraction of the stamping equipment as a can cover stamping in another direction, and the can body and the can cover are stamped successively, which greatly improves the processing efficiency and effectively reduces the processing cost. This patented technology solves the problem that the stamping equipment in the prior art can only stamp the can cover or the can body separately, and requires the cooperation of multiple equipment to complete the overall processing of the can, which has low efficiency and high processing costs. It can design a can processing equipment that can perform bidirectional stamping, and stamp the can body and the can cover at the same time, thereby improving processing efficiency and reducing production costs.

[0003] However, in the prior art, when cans are formed, the lack of lubricating oil supply in the extrusion die easily causes friction deformation of the stamped aluminum plate. Therefore, it is necessary to solve the problem of automatically applying lubricating oil to the extrusion die in the prior art.

When the aluminum coil is transmitted on the stamping base structure 3, the servo motor 202 is controlled, and the servo motor 202 drives the aluminum material receiving rod 203 to rotate. The rotating aluminum material receiving rod 203 rotates the driving pulley 211 while unloading the aluminum coil. The driving pulley 211 drives the driven pulley 305 to rotate through the belt 212. The driven pulley 305 rotates the stamping machine table 302 twice by 15 degrees, and the aluminum plate is placed on the forming inner mold 303 of the stamping machine table 302; The servo motor 317 rotates to drive the transmission rod 318 to rotate, so that the transmission rod 318 drives the bevel gear 319 to rotate, and the rotating bevel gear 319 meshes with the bevel gear 4 320 to rotate, and the driving rod is rotated by the rotating bevel gear 4 320, and the worm 321 rotates with the driving rod, meshing and rotating the worm wheel 322, so that the reciprocating screw 323 fixed by the worm wheel 322 rotates 180 degrees, so that the reciprocating screw barrel 328 and the lubricating cotton 329 on its outer side are lowered to the inside of the forming inner mold 303, and the inside of the forming inner mold 303 can be lubricated with lubricating oil through the lubricating cotton 329; When the lubricating cotton 329 is coated with lubricating oil, the lubricating oil in the lubricating oil tank is extracted by the oil supply pump, and the lubricating oil is discharged into the oil supply groove 327 through the oil supply pipe 326. The lubricating oil flows into the inner side of the lubricating cotton 329 through the oil supply groove 327, which is conducive to the lubricating oil being supplied to the lubricating cotton 329; When the punching machine table 302 rotates at an angle of 15°, the rotating driven pulley 305 rotates synchronously with the spur gear ring 306, and the rotating meshing spur gear 307 of the spur gear ring 306 rotates 180°. The rotating spur gear 307 drives the driven rod 308 to rotate, and the driven rod 308 rotates the helical gear 1 309, and the rotating helical gear 1 309 meshes with the helical gear 2 310 to rotate. The rotating helical gear 2 310 drives the transmission plate 311 to rotate 180°, and the transmission plate 311 is used to extend the transfer rod 313 through the transfer frame 312, so that the transverse frame plate 314 is moved to the outside of the punching machine table 302, and is located directly above the three-stage stretching inner die 8; When the punching machine table 302 rotates by 15° twice, the transmission plate 311 rotates by 180° twice, so that the transverse frame plate 314 can be automatically reset to the inner side of the punching machine table 302, which is beneficial to the stamping forming of the aluminum plate. After the main stamping hydraulic rod 406 is started to rotate, the main stamping hydraulic rod 406 is pushed downward to push the stamping plate 405 to exert force on the pressure plate 404. After the pressure plate 404 is lowered, the stamping die 403 at the bottom of the pressure cylinder 402 shears the aluminum plate into a disc shape. The sheared aluminum disc is started by the stamping hydraulic rod 410 to lower the stamping die rod 407 to the inside of the stamping die 403. The aluminum disc is stamped to form the prototype of the can through the cooperation of the stamping die rod 407 and the forming inner mold 303. The can prototype after stamping falls into the inner side of the aluminum can slot 315 of the transverse frame plate 314. The transverse frame plate 314, which is rotated at an angle in sequence, will be positioned directly below the extrusion and stretching die rod 6 as the transverse frame plate 314 moves. The extrusion cylinder device 7 is started to apply pressure to the three-stage stretching inner die 8 for the extrusion and stretching die rod 6 to stretch the can in three stages to form the can body, and drop it onto the conveyor belt 12. The servo motor 11 is started to drive the transmission roller to rotate, so that the conveyor belt 12 on the transmission roller moves, and the can can be transported and moved to the outside.
