Description

Technical Field

[0001] The utility model relates to the technical field of fishhook production, in particular to a bending device for fishhooks. Background Technique

[0002] The production of fishhooks needs to go through five steps: material taking, cutting, sharpening, barbing, and bending. Bending is an important step. A special bending device is used to bend a straight metal rod into the shape of a hook by stamping; Application No.: CN202011229882.0, "A fishhook bending device for fishing gear production". When in use, the first electric telescopic rod drives the bending seat to move. When the first electric telescopic rod is in the shortest state, the bending seat moves below the funnel. The user puts the metal rod into the through hole, and the metal rod automatically falls, then passes through the funnel, and the metal rod falls into the placement groove on the top of the bending seat. The first electric telescopic rod pushes the bending seat, and the bending seat moves below the mold. The second electric telescopic rod pushes the mold to move downward, and the mold squeezes the metal rod, and the metal rod becomes bent. The fishhook completes the bending process. Then the third electric telescopic rod pushes the push plate, and the push plate pushes the metal rod upward. The metal rod automatically disengages from the placement groove and falls onto the sliding table.

[0003] The diameters of the metal rods used for fishhooks of different sizes are different, but the size of the placement groove of this fishhook bending device is fixed, and the size of the placement groove cannot be adjusted according to the diameter of the metal rod, which is not convenient for limiting metal rods of different diameters. When bending metal rods of different diameters, this fishhook bending device is not convenient to use. Summary of the Utility Model

After adjusting the distance between the two limiting rods 12 to an appropriate distance according to the diameter of the metal rod 26, the metal rod 26 is placed between the two limiting rods 12 to achieve the limiting effect on the metal rod 26; then the motor 25 rotates counterclockwise, and the screw rod 23 drives the rotating seat 22 to move in the direction of the pressing head 11. The rotating seat 22 drives the entire limiting assembly 2 and the metal rod 26 to move in the direction of the pressing head 11. When the metal rod 26 moves below the pressing head 11, it stops moving; then the hydraulic cylinder 6 is started, and the hydraulic cylinder 6 pushes the pressing head 11 to punch and bend the metal rod 26.
