Description

Technical Field

[0001] The utility model relates to the technical field of feeding equipment, in particular to a double-station stamping automatic feeding machine. Background Technique

[0002] Automated stamping lines are commonly used in the sheet metal stamping industry, which basically consist of a punching press, a manipulator, and a feeding machine. The feeding machine is used to place the raw material plate before stamping. After the manipulator accurately positions the raw material plate, it picks it up and directly feeds it into the mold for stamping. Among them, the design requirement of the feeding machine is to meet continuous feeding.

[0003] For existing feeding machines, for example, a hydraulic feeding machine disclosed in CN111151674A includes a frame, a moving table, a secondary positioning device for picking and placing sheet metal, a sheet metal loading lifting device, a sheet metal lifting device, an electro-hydraulic control device, etc. The frame is provided with a secondary positioning device for picking and placing sheet metal, two sheet metal loading lifting devices, and a sheet metal lifting device; the moving table reciprocates on the frame through the electro-hydraulic control device, and when positioning, one end of the loading station is aligned with one sheet metal loading lifting device, and the other end of the loading station that has completed loading is aligned with one sheet metal lifting device. The forklift sends the neatly arranged stack of sheet metal into the missing loading station. After the sheet metal loading lifting device lifts to make the stack of sheet metal leave the forklift arm, the forklift exits. The sheet metal loading lifting device descends to place the stack of sheet metal on the loading station. At the same time, the sheet metal lifting device jacks up the sheet metal for the secondary positioning device for picking and placing sheet metal to pick it up and position it on the secondary positioning platform.

[0004] During the feeding process of the existing raw material plate on the feeding machine, due to environmental factors and the defects of the raw material plate itself, there will be a certain deformation problem in the raw material plate. Even a slight deformation will affect the quality of the subsequent stamped sheet metal parts and cause defective products. Content of the Utility Model

[0025] Please refer to Figures 1-4, A double-station stamping automatic feeding machine, including a device main body 1, on which a first conveyor belt 2 and a second conveyor belt 3 are arranged. Between the first conveyor belt 2 and the second conveyor belt 3, a flattening roller group 4 is arranged. On the device main body 1, four symmetrically arranged limit plates 6 are arranged. Every two corresponding limit plates 6 form a bin. On one side of the device main body 1, a protective housing 5 is installed. A cavity 9 is opened in the protective housing 5. In the cavity 9, a motor bracket 10 is arranged. A servo motor 11 is installed on the motor bracket 10. On the action output shaft of the servo motor 11, a driving gear 12 is installed. In the cavity 9, a sliding rod 7 is slidably installed. On the sliding rod 7, a driven tooth groove 14 meshing with the driving gear 12 is arranged. On the sliding rod 7, two symmetrically arranged movable push rods 8 are arranged. Both of the two movable push rods 8 extend into the bin.

[0026] Through the mutual cooperation of structures such as the two bins, the servo motor 11, the driving gear 12, the sliding rod 7, and the movable push rods 8, when working, raw material plates can be added into the bins manually or by a forklift. The servo motor 11 drives the driving gear 12 to rotate reciprocally, thereby causing the sliding rod 7 to move reciprocally in the horizontal direction, and further causing the two movable push rods 8 to move reciprocally synchronously in the two bins. Then, the raw material plates at the bottom of the two bins can be reciprocally and alternately fed onto the first conveyor belt 2, and the raw material plates are conveyed to the flattening roller group 4 by the first conveyor belt 2. The raw material plates are flattened and corrected by the flattening roller group 4 to ensure the qualification rate of the raw material plates before stamping, and thus ensure the stamping quality.

[0027] Specifically, in this embodiment, a receiving groove 13 is opened on the inner wall of the bottom of the bin formed by the limit plate 6. The size of the receiving groove 13 is adapted to the movable push rod 8, so that the movable push rod 8 can slide into the receiving groove 13, causing the raw material plates in the bin to lose support and fall, thus facilitating the movable push rod 8 to push the bottommost raw material plate from the bin onto the first conveyor belt 2.

[0028] Specifically, in this embodiment, a rectangular notch 18 is opened at the bottom of the limit plate 6 close to the protective housing 5. The size of the rectangular notch 18 is adapted to the movable push rod 8. Through the setting of the rectangular notch 18, it is convenient for the movable push rod 8 to slide in the rectangular notch 18, achieving the purpose of guiding the moving direction of the movable push rod 8.

[0029] Specifically, in this embodiment, two symmetrically arranged mounting plates 17 are arranged in the cavity 9. Between the two mounting plates 17, a sliding rod 16 is arranged. The sliding rod 7 is slidably arranged on the sliding rod 16. A sliding hole 15 is opened on the sliding rod 7. The diameter of the sliding hole 15 is adapted to the diameter of the sliding rod 16.

[0030] Through the mutual cooperation of the sliding rod 16 and the sliding bar 7, the sliding bar 7 can slide along the sliding rod 16 through the sliding hole 15, guiding the moving direction of the sliding bar 7 and restricting the moving range of the sliding bar 7.

[0031] Specifically, in this embodiment, an installation groove 19 is formed in the device main body 1, and both the first conveyor belt 2 and the second conveyor belt 3 are arranged in the installation groove 19.

[0032] Specifically, in this embodiment, the thickness of the movable push rod 8 is lower than the thickness of the raw material plate, which facilitates the movable push rod 8 to push the lowermost raw material plate in the storage bin.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
