Description

Technical Field

[0001] The utility model relates to the technical field of fin processing, in particular to a fin feeding mechanism. Background Art

[0002] In the continuous processing of the fins of the two devices, the fins need to be driven forward by the feeding mechanism to complete the continuous processing of the fins. The existing feeding structure mainly includes a movable feeding mechanism that moves back and forth along the fin conveying direction and a fixed feeding mechanism arranged at the front end of the movable feeding mechanism. Both the movable feeding mechanism and the fixed feeding mechanism are provided with retractable feeding fingers. The feeding fingers of the movable feeding mechanism are used to hook the fins and convey them forward. After reaching the set position, the feeding fingers on the fixed feeding mechanism hook the fins, and the feeding fingers of the movable feeding mechanism are retracted and separated from the fins. The movable feeding mechanism moves back to the initial position to prepare for the next feeding. A spring is arranged under the feeding finger, and the feeding finger is retracted by the downward pressure.

[0003] As the thickness of the fin aluminum foil decreases and the running speed increases, the feeding finger of the traditional spring structure may scrape against the fin during the return process of the movable feeding mechanism due to untimely retraction, thereby causing scratches on the fin surface. At the same time, the existing movable feeding mechanism uses a punch press to drive the crank connecting rod to move. The other end of the crank connecting rod is connected to the movable feeding mechanism, which pulls the movable feeding mechanism back and forth. This structure has large vibrations and unstable feeding. The faster the speed, the greater the vibration and the worse the feeding stability. Therefore, the existing punch press drive structure cannot meet the needs of high-speed fin feeding and production and processing. It is necessary to adjust the driving mode of the feeding mechanism to increase the running speed and ensure the running stability. Utility Model Content

[0004] The utility model aims to provide a fin feeding mechanism to solve the problem that the existing fin feeding mechanism is easy to scratch the fins during high-speed feeding.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a fin feeding mechanism, including a lower die base, a movable feeding mechanism and a fixed feeding mechanism arranged on the lower die base; the movable feeding mechanism includes a movable feeding plate, a group of feeding fingers arranged on the movable feeding plate, the movable feeding plate is provided with a vertically arranged gas flow channel below the feeding fingers, and is also provided with a main air channel that runs through all the gas flow channels, and the movable feeding plate is also provided with an intake pipe joint and an exhaust valve connected to the main air channel, the intake pipe joint is externally connected to the intake pipeline, and the exhaust valve is connected to a vacuum pump; the fixed feeding mechanism includes a fixed feeding plate and a group of feeding fingers arranged on the fixed feeding plate, and the fixed feeding plate is provided with a vertically arranged gas flow channel below the feeding fingers.

[0006] Furthermore, a pad is provided below the movable feed plate, and a movable feed cover is provided above the movable feed cover, and a group of clearance holes for the feeding fingers to extend out are provided on the movable feed cover; a fixed feed cover is provided above the fixed feed plate, and a group of clearance holes for the feeding fingers to extend out are provided on the fixed feed cover.

[0007] In order to improve the speed and stability of the movable feeding mechanism, a servo electric cylinder driving the movable feeding mechanism to move back and forth is arranged on the lower die seat, and a connecting flange is arranged between the movable end of the servo electric cylinder and the pad.

[0008] Furthermore, a sliding block is arranged on the pad, and two mutually parallel guide rails are arranged on the lower die base.

[0009] In order to reduce the weight of the feeding finger and reduce the gas pressure required to push the feeding finger out, a weight-reducing countersunk hole with a bottom opening is arranged on the feeding finger.

[0010] In order to prevent foreign matter from falling onto the fins, a cover plate is further arranged above the movable feeding cover plate.

[0011] Beneficial effects of the utility model: the utility model drives the feeding finger to move up and down through the pneumatic structure. When feeding is needed, the feeding finger extends, and when the movable feeding mechanism moves back, the feeding finger retracts into the movable feeding cover plate, thereby effectively preventing the feeding finger from scratching the fins and improving the qualified rate of the product. The movable feeding mechanism is driven by a servo electric cylinder, which has the advantages of fast speed and good stability. Therefore, the feeding stability can be guaranteed and the feeding efficiency can be improved.
