Description

Technical Field

[0001] The invention belongs to the technical field of riveting production lines, and in particular relates to a riveting production line for automatic processing of aluminum profiles and angle codes. Background Art

[0002] Aluminum profiles and angle brackets usually need to be riveted, and the aluminum profiles often need to be cut and punched before riveting. Generally, the existing production lines often have a low degree of automation, and the punching and cutting of aluminum profiles are separate operations, resulting in low overall processing efficiency of aluminum profiles. When processing aluminum profiles, the two end faces of the aluminum profiles are often cut first; since the size of aluminum profiles is often large, the position of the positioning mold needs to be adjusted each time the aluminum profile is sent to the cutting station, and the operation steps are cumbersome. At the same time, both end faces of the aluminum profile need to be cut. After one end face is cut, the aluminum profile needs to be manually turned and then cut again, which has low cutting efficiency. After the aluminum profile is cut, it is manually placed on the punching die for punching. Since the punching is done manually, the positioning effect is poor, resulting in poor punching effect. After the aluminum profile is punched, the aluminum profile and the angle bracket are connected through a riveting device. Since the number of angle brackets and aluminum profiles to be processed is large, manual feeding is often slow, resulting in low riveting efficiency for the two and low overall processing efficiency of the product. Therefore, it is necessary to design an automatic riveting production line for aluminum profiles and angle codes to overcome the above difficulties. Summary of the invention

[0034] The specific operation process of this embodiment is as follows: in the initial state, the aluminum profile to be cut is automatically grabbed and placed on the end face cutting component 21 through the second material transfer component 7; before the aluminum profile is cut, the two ends of the aluminum profile are fixed by the positioning components 23 arranged adjacent to it, and then the cutting blade component 22 starts to work to cut the aluminum profile; when the first motor 226 is working, it drives the blade body 223 to rotate, thereby cutting the aluminum profile; when the second motor 227 is working, it drives the gear to rotate, and the gear and the rack are meshed with each other; then at this time, the first platform 225 can move relative to the cutting guide plate 222 along the first track 224, so that the blade body 223 is close to or away from the aluminum profile. When the first cylinder 221 is working, it can drive the rotating shaft of the cutting guide plate 222 to rotate, so that the cutting guide plate 222 can rotate relative to the cutting base 211, so that the blade body 223 can achieve different angles of cutting of the aluminum profile, and the versatility is better. After the end face cutting of the aluminum profile is completed, the first material transfer component 25 transports the aluminum profile from the positioning component 23 to the first material transfer support 26; then the cutting and unloading component 24 works to transport the aluminum profile to the loading and conveying component 36 of the punching mechanism 3, and then the punching mechanism 3 performs punching operations on the aluminum profile.

[0035] The clamping assembly 34 first fixes the aluminum profile. When the second cylinder 342 is working, it drives the rack to move axially relative to the clamping shield 341. The rack and the gear mesh with each other, so that the gear drives the pressing block shaft 343 to rotate relative to the punching frame 32; when the pressing block shaft 343 rotates, it drives the clamping member 344 to turn, so that the clamping member 344 clamps and fixes the aluminum profile on the positioning mold 33. After the aluminum profile is fixed, the punching device 35 starts to work; when the first oil cylinder 353 is working, it drives the bar push rod 354 to move, and when the bar push rod 354 moves, it drives the punching movable side plate 351 to move along the fifth track 37 close to the positioning mold 33; when the punching movable side plate 351 moves, it drives the punching mold 352 to punch the aluminum profile. Since the movement of the punching mold 352 is controlled by the first oil cylinder 353, the punching force is uniform and the punching effect is better. Then the loading and unloading synchronous conveying assembly 31 starts to synchronously convey the aluminum profile, and the second rotating motor 312 drives the end of the second connecting rod 316 to move along the path of the second track plate 313 when it is working; since the horizontal moving plate 314 can only move horizontally relative to the punching transfer seat 311, the vertical frame 315 can only move vertically relative to the horizontal moving plate 314; the end of the second connecting rod 316 away from the second rotating motor 312 is hinged to the vertical frame 315, so when the end of the second connecting rod 316 moves, it can drive the vertical frame 315 to move along the path of the second track plate 313; two groups of second clamping claw cylinders 317 arranged in pairs are provided on the vertical frame 315, so the first group of the second clamping claw cylinders 317 can convey the aluminum profile from the loading and conveying assembly 36 to the positioning mold 33; the second group of the second clamping claw cylinders 317 can convey the aluminum profile from the positioning mold 33 to the riveting mechanism 4. The loading and unloading process is completed simultaneously by the loading and unloading synchronous conveying assembly 31, the material transfer speed is faster, and the overall processing efficiency of the product is improved.

[0036] Then the riveting mechanism 4 starts to work, and the operator places the angle code hopper 417 with the angle code on the eighth track 416 in sequence, and then the servo motor 415 works to control the angle code moving plate 411 to move along the seventh track 414; here, the servo motor 415 works to align the angle code hopper 417 with the pushing clamp arm device 46, so that the pushing clamp arm device 46 works to push the angle code hopper 417 and the eighth track 416 to the initial end of the feeding track 412. Then the feeding cylinder 413 works to control the pushing plate 418 to extend into the hole of the angle code hopper 417, so that the angle codes in the angle code hopper 417 will be pushed into the feeding track 412 in sequence; because the feeding track 412 is provided with a track guide plate 419, the angle codes will be arranged side by side in sequence. Then the angle codes will be transported to the angle code riveting assembly 42 through the feeding track 412 for processing.

[0037] The angle code will be pushed onto the angle code conveyor 423 along the feeding track 412, and then the angle code conveyor 423 will work to transport the angle code to the vicinity of the riveting die head 426; before riveting, the fifth cylinder 428 controls the limit push plate 429 to extend; in this way, the limit push plate 429 will push the angle code at the end of the angle code conveyor 423 to the bottom of the riveting die head 426, and at the same time, the limit push plate 429 will separate the remaining angle codes, so that the single angle code can be riveted in turn; when the angle code is directly below the riveting die head 426, the first positioning cylinder 424 controls the first positioning piece 427 to limit the side of the angle code; the second positioning cylinder 425 works to limit the upper end face of the angle code; when the fourth clamping jaw cylinder 10 works, the aluminum profile is clamped and limited. Here, the mounting plate body 421 and the riveting frame 45 are slidably connected, so that the spacing between the two angle code riveting assemblies 42 can be adjusted conveniently, and the processing of aluminum profiles of different lengths can be adapted conveniently, and the versatility is better. When the limit cylinder 92 is working, it pushes the aluminum profile to move relative to the feeding synchronous belt 43, so that the end of the aluminum profile will push the measuring push plate 96 to move, and when the measuring push plate 96 moves, it drives the telescopic rack 95 to move, and the movement of the telescopic rack 95 drives the measuring gear 97 to rotate; then the rotary encoder 93 can detect the number of rotations of the measuring gear 97, and by measuring the number of rotations of the gear 97, the rotary encoder 93 can automatically convert the axial length of the aluminum profile, thereby detecting whether the length of the aluminum profile is qualified.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
