[0047] Specifically, in this embodiment, the front-to-back position of the core rod 1737 can be adjusted by adjusting the front-to-back position of the L-shaped connecting block 17364 on the second connecting block 17362. The core rod 1737 is mounted on the connecting column 17365 by screws. When it needs to be replaced, it is only necessary to loosen the screws and pull the core rod 1737 out from the bottom of the connecting column 17365.

[0048] See also Figure 1 and Figure 2 In a preferred embodiment of the present application, the intermittent pressing assembly 174 includes a second mounting block 1741 mounted on the bottom of the frame 10, and a pressing rod 1742 rotatably disposed at the bottom of the second mounting block 1741;

[0049] One end of the pressing rod 1742 contacts the first bearing 17363 , and the other end is provided with a connecting rod 1743 . A second bearing 1744 is provided on the end surface of the connecting rod 1743 , and the second bearing 1744 contacts the cam driving assembly 12 .

[0050] Specifically, in this embodiment, when the cam of the cam driving assembly 13 is in the push stroke, the second bearing 1744 and the connecting rod drive the pressing rod 1742 to press down the first bearing 17363, so that the connecting assembly 1736 drives the mandrel 1737 to descend, so that the rounded fishhook can enter the next process.

[0051] When the cam of the cam driving assembly 13 at this position is in the return stroke, the second bearing 1744 and the connecting rod 1743 drive the pressing rod 1742 to be lifted up, and under the self-restoring force of the first spring 1735, the long slider 1733, the end cover 1734 and the connecting assembly 1736 are lifted up, and the connecting assembly 1736 drives the core rod 1737 to be lifted up to position the semicircular position of the fishhook.

[0052] See also Figure 1 and Figure 2 In a preferred embodiment of the present application, a thimble is installed on the top of the core rod 1737, and the thimble passes through the positioning support block 171 to position the semicircular position of the fish hook. The thimble is installed in the core rod 1737 by a screw to facilitate replacement.

[0053] See also Figure 1 、 Figure 3 and Figure 4 In a preferred embodiment of the present application, the hook body forming assembly 20 includes a fixed backing 201 and a movable backing 202 installed on the frame 10, and a forming pushing assembly 203 installed on the side wall of the support frame 12 and connected to the cam driving assembly 13.

[0054] It should be noted that in this embodiment, the use of a double-sided movable backing mold in a single fixed, movable configuration improves hook forming accuracy. Specifically, when the fishhook reaches this stage, the movable backing mold 202 approaches the fixed backing mold 201 to secure the fishhook. The cam drive assembly 13 then rotates the distal end of the forming push assembly 203 to bend the fishhook, completing the forming process.

[0055] See also Figure 3 and Figure 4 In a preferred embodiment of the present application, the fixed mold 201 includes a first pad 2011 mounted on the frame 10, a screw 2012 passing through the first pad 2011, and a first module 2013 provided on the first pad 2011 and in contact with the end of the screw 2012;

[0056] The movable backing 202 includes a second pad 2021 mounted on the frame 10, a backing slide rail 2022 provided on the second pad 2021, and a backing slider 2023 provided on the backing slide rail 2022;

[0057] A second module 2024 is installed at one end of the profiling slider 2023 , and a third bearing 2025 is installed at the other end. The third bearing 2025 is in contact with and connected to the lifting drive assembly 204 .

[0058] Specifically, in this embodiment, by adjusting the position of the screw 2012 on the first cushion block 2011, the angle of the first module 2013 on the first cushion block 2011 is adjusted, thereby processing different hook shapes.

[0059] See also Figure 1 、 Figure 3 and Figure 5 In a preferred embodiment of the present application, the lifting drive assembly 204 includes a sleeve 2041 mounted on the frame 11, and a lifting slider 2042 slidably disposed in the sleeve 2041;

[0060] The top surface of the lifting slider 2042 is an inclined surface, which contacts the third bearing 2025;

[0061] The bottom surface of the lifting slider 2042 is provided with a baffle 2043, and the bottom is sleeved with a fourth spring 2044, and the fourth spring 2044 is in contact with the baffle 2043 and the sleeve 2041 respectively;

[0062] A swing arm 2045 is rotatably mounted on the bottom of the frame 10 , one end of the swing arm 2045 contacts the baffle 2043 via an arc-shaped protrusion, and the other end contacts the cam driving assembly 13 via a fifth bearing.

[0063] Specifically, in this embodiment, when the cam of the cam driving assembly 13 at this position is in the push stroke, the end of the swing arm 2045 is driven to swing downward by the fifth bearing 2025. Under the action of the restoring force of the fourth spring 2044, the lifting slider 2042 slides downward, and the movable backing plate 202 moves away from the fixed backing plate 201.

[0064] When the cam of the cam drive assembly 13 at this position is in the return stroke, the end of the swing arm 2045 is driven to swing upward through the fifth bearing 2025, compressing the fourth spring 2044, so that the lifting slider 2042 slides upward, and the movable support mold 202 approaches the fixed support mold 201.

[0065] See also Figure 3In a preferred embodiment of the present application, the forming pushing assembly 203 includes a first fixed block 2031 mounted on the support frame 12, a forming slide rail 2032 provided on the first fixed block 2031, and a forming slider 2033 provided on the forming slide rail 2032;

[0066] One end of the forming slider 2033 is connected to the forming rocker 2035 via a rack and pinion assembly 2034, and the other end is connected to the cam drive assembly 13 via a swing assembly 2036;

[0067] A second spring 2037 and a blocking bolt are sleeved on one end of the forming slider 2033 close to the swing assembly 2036 , and the second spring 2037 is in contact with the blocking bolt and the forming slide rail 2033 .

[0068] It should be noted that, in this embodiment, by adopting the rack and pinion assembly 2034 to replace the existing chain transmission mode, during the forming process, no limit block is required for positioning, the return angle can be controlled, and higher cam accuracy is not required.

[0069] Specifically, when the cam of the cam driving assembly 13 is in the push stroke, the forming slider 2033 is pushed forward by the swing assembly 2036, and the rack and pinion assembly 2034 drives the forming swing rod 2035 to rotate, so as to bend and form the fishhook;

[0070] When the cam of the cam driving assembly 13 at this position is in the return stroke, the swing assembly 2036 drives the forming slider 2033 to slide backward, and the rack and pinion assembly 2034 drives the forming rocker 2035 to return to its position. At the same time, the movable support mold 202 moves away from the fixed support mold 201, and the bent and formed fish hook falls into the receiving box.

[0071] See also Figure 3 In a preferred embodiment of the present application, the swing assembly 2036 includes a second fixed block 20361 mounted on the frame 10, a swing rod 20362 rotatably connected to the second fixed block 20361, and a push rod 20363 rotatably connected to the end of the swing rod 20362;

[0072] The other end of the push rod 20363 is rotatably connected to the forming slider 2033 , and a fourth bearing 20364 is provided on the side wall of the rocker arm 20362 , and the fourth bearing 20364 is in contact with the cam driving assembly 13 .

[0073] See also Figure 5In a preferred embodiment of the present application, the top surface of the frame 10 is tilted backward and downward, so that the loading box is tilted. Since the impact force during the processing will cause the entire equipment to vibrate, the tilted loading box can prevent the material to be processed from falling out of the loading box.

[0074] In summary, the present invention achieves the following advantages: first, by mounting the mandrel 1737 at the bottom of the frame 10, it can be easily replaced if it breaks, thereby improving replacement efficiency. Second, by replacing the double-sided movable backing with one fixed and one movable, the hook forming accuracy can be improved. Third, by replacing the existing chain drive with a rack and pinion assembly 2034, the forming process eliminates the need for a stop block, allowing for controlled return angles and eliminating the need for higher cam precision.
