Therefore, they should not be construed as limitations on the embodiments.
[0017] The production of double-hook fishhooks mostly adopts manual bending or automated equipment bending methods: manual bending is inefficient and has poor forming accuracy, making it difficult to ensure the symmetry and dimensional consistency of the double hooks; existing automated bending equipment has a complex structure and high manufacturing cost, and is mostly designed for fishhooks of fixed specifications, making it inconvenient to adjust and unable to flexibly adapt to the production needs of double hooks of different lengths, making it unsuitable for small and medium-sized production scenarios.
[0018] After recognizing the above problems, this application proposes and discloses a bending device for fish hook production that is simple in structure, easy to operate, has high forming accuracy, and can be adapted to fish hooks of different lengths.
[0019] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, a bending device for fishhook production provided in this embodiment includes: Abutment 1; A bending unit 2 is mounted on a base 1. The bending unit 2 includes a fixed plate 21, a movable block 22, a bending clamp 23, and a tightening block 24. The fixed plate 21 is fixedly mounted on the base 1, and a guide groove 211 is provided on its upper end face. The movable block 22 can slide along the guide groove 211. The hinge shaft of the bending clamp 23 is fixedly mounted on the movable block 22, and its clamp head extends out of the front end of the movable block 22. The tightening block 24 is fixedly mounted on the front end of the fixed plate 21 by bolts and is symmetrically distributed on both sides of the movable block 22. The outer sides of the left and right clamp handles of the bending clamp 23 are provided with protrusions 231. When the movable block 22 moves forward along the guide groove 211, it drives the bending pliers 23 with its jaws open to move forward synchronously. When the jaws approach the fish hook to be processed, the protrusions 231 on the outer sides of the left and right handles of the bending pliers 23 are squeezed by the tightening blocks 24 on both sides, and the jaws gradually close, thereby bending the double-hook fish hook so that the two fish hooks are folded outwards.
[0020] The drive unit 3 is hinged to the rear end of the base 1, and its drive end is connected to the movable block 22. The positioning unit 4 is fixedly installed at the front end of the base 1 and is located near the jaws of the bending clamp 23; The reset unit 5 is fixedly located at the rear end of the bending unit 2. Its reset end is connected to the handle of the bending pliers 23 and is used to reset the jaws when the bending pliers 23 retracts.
[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the positioning unit 4 includes a center block 41, a mounting block 42, a placement component 43, and a pin 44. The center block 41 is fixedly mounted on the front end of the base 1 and is positioned close to the head of the bending pliers 23. The mounting block 42 is symmetrically arranged on both sides of the center block 41. The placement component 43 is detachably mounted on the mounting block 42 and is used to support the double-hook fishhook to be processed. The pin 44 is vertically mounted on the center block 41, and the pin 44 and the hinge axis of the bending pliers 23 are on the same axis.
[0022] During processing, the ends of the semi-finished fish hooks with hooks at both ends are placed on the placement pieces 43 on both sides, with the bent ends of the fish hooks facing the movable block 22 and the back of the fish hooks abutting against the ejector pin 44. When the jaws of the bending pliers 23 approach, the left and right jaws squeeze the two ends of the fish hooks, causing them to bend towards the rear of the ejector pin 44. As the jaws continue to advance and tighten, the ejector pin 44 enters the inside of the jaws, and the clamping part of the jaws bends the fish hooks, ultimately forming a double-hook fish hook. When the drive unit 3 drives the bending pliers 23 to retract into the guide groove 211, the double-hook fish hooks can be taken out from the top of the ejector pin 44.
[0023] like Figure 5 As shown, the placement component 43 includes a positioning plate 431 and a placement plate 432. The placement plate 432 is fixed to the end of the positioning plate 431 and is located near the center block 41. The positioning plate 431 has a positioning groove 4311. The mounting block 42 has a fastener 421. The positioning plate 431 is fixed to the mounting block 42 by the cooperation of the fastener 421 and the positioning groove 4311, thereby adjusting the distance between the two placement plates 432 to accommodate different fishhook lengths.
[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the drive unit 3 includes a crank drive rod 31, a shaft 32, a pedal 33, and a push plate 34. The shaft 32 movably passes through the crank drive rod 31 and is located near the upper end of the crank drive rod 31. The pedal 33 is fixed to the lower end of the crank drive rod 31. One end of the push plate 34 is hinged to the upper end of the crank drive rod 31. The base 1 has two sets of fixing blocks 11 integrally provided at its rear end. The shaft 32 is provided through the two sets of fixing blocks 11. The crank drive rod 31 is movably provided between the two sets of fixing blocks 11. The movable block 22 has a push block 221 at its rear end, and the other end of the push plate 34 is hinged to the push block 221.
[0025] In this embodiment, by stepping on the pedal 33, the crank drive rod 31 can rotate around the shaft 32, which in turn drives the push plate 34 to push the push block 221. Finally, the push block 221 drives the movable block 22 to move along the guide groove 211 toward the positioning unit 4.
[0026] like Figure 1 , Figure 2 and Figure 3As shown, the reset unit 5 includes a crossbar 51, a connecting plate 52, a fixing rod 53, and a reset spring 54. The crossbar 51 is fixedly mounted on the push block 221, the connecting plate 52 is fixedly mounted on both ends of the crossbar 51, the fixing rod 53 is mounted on the end of the handle of the bending pliers 23, one end of the reset spring 54 is fixed to the connecting plate 52, and the other end of the reset spring 54 is fixed to the fixing rod 53.
[0027] When the drive unit 3 moves the bending pliers 23 closer to the positioning unit 4, the protrusions 231 on the outer sides of the left and right handles of the bending pliers 23 are squeezed by the tightening blocks 24 on both sides, and the left and right handles move closer to each other, and the return spring 54 is stretched; when the drive unit 3 moves the bending pliers 23 away from the protrusions 231, the return spring 54 pulls the handles away from each other, and the jaws of the bending pliers 23 open and return to their original position.
[0028] like Figure 1 and Figure 2 As shown, a workbench 6 is provided below the base 1, and a through groove 61 is provided on the workbench 6, through which the crank drive rod 31 is movably connected.
