[0025] The feeding piece 3 is provided with a containing groove 32, and a feeding hook 321 is rotationally connected in the containing groove 32. The rotating part of the feeding hook 321 is arranged close to the feeding insert 121. The top of the end of the feeding hook 321 away from the feeding insert 121 is provided with a hook-shaped part, which extends into the through hole of the product. The inner bottom wall of the containing groove 32 is provided with a first elastic member 322 for driving the hook-shaped part to extend out of the containing groove 32.

The side of the hook-shaped part away from the feeding insert 121 forms a contact surface and can extend into the through hole of the product to abut against the inner wall. By arranging the guide surface, when the product contacts the guide surface, a downward pressure is applied to the feeding hook 321 due to the guiding effect, so that the feeding hook 321 is retracted into the containing groove 32. At this time, the first elastic member 322 is compressed under stress and smoothly passes through. The hook-shaped part of the feeding hook 321 corresponds to the through hole on the product. The elasticity of the first elastic member 322 makes the feeding hook 321 reset and extends the hook-shaped part into the through hole of the product.

The arrangement of the feeding cover plates 4 can also protect the feeding structure, ensuring the service life of the overall structure.
[0027] The product strip is provided with a check hole. The bottom of the feeding cover plate 4 is provided with a check hook 41 for limiting the backward movement of the product. The second elastic member 42 is arranged between the check hook 41 and the feeding cover plate 4. The second elastic member 42 has an elastic deformation potential for driving the check hook 41 to approach the lower die plate 22. The end of the check hook 41 away from the second elastic member 42 is provided with a chamfer. The check hook 41 extends into the check hole of the product strip and contacts the inner side wall of the check hole, which can limit the backward movement of the product. The chamfer is arranged. When the feeding hook 321 feeds the product, the guiding effect of the chamfer makes the check hook 41 approach the feeding cover plate 4, and the second elastic member 42 is compressed, which does not hinder feeding.
[0028] Working principle: The product passes through the limiting plate 43 between the two limiting plates 43. The limiting plate 43 limits the displacement of the product in the horizontal width direction, ensures the displacement trajectory, and transports the product to the feeding hook 321, so that the hook-shaped part on the feeding hook 321 extends into the through hole of the product to complete positioning.
[0029] The upper die holder 1 is driven to approach the lower die holder 2, the feeding insert 121 extends into the sliding groove 221 and touches the rolling shaft 33, the feeding insert 121 end is chamfered, thus the whole feeding piece 3 is pushed to move, the reset elastic piece is deformed under the external force, the hook-shaped part arranged on the top of the feeding piece 3 is in contact with the product, the product is driven to move, and when the product moves, the inclined surface on the floating material block 6 is touched, the product is driven to float upwards, thus the product is moved towards the upper side of the carrier, the chamfer on the check hook 41 is in contact with the product while the product moves, the check hook 41 is driven to approach the feeding cover plate 4 by the guiding effect of the chamfer, and the second elastic piece 42 is compressed; until the upper die holder 1 and the lower die holder 2 are completely close to each other, the feeding insert 121 is completely inserted into the sliding groove 221, at this time, the check hook 41 corresponds to the check hole on the product, the second elastic piece 42 is not affected by the external force, the check hook 41 is inserted into the check hole by the elasticity of the second elastic piece 42, and the product is prevented from retreating;
[0030] When the upper die holder 1 is away from the lower die holder 2, the feeding insert 121 is away from the sliding groove 221, the reset elastic piece is not affected by the external force, and the feeding piece 3 is reset by the elasticity of the reset elastic piece, at this time, the guiding surface on the end hook-shaped part of the feeding hook 321 is in contact with the product, the feeding hook 321 is driven to rotate towards the containing groove 32 under the guiding effect, the first elastic piece 322 is compressed under the force, and the feeding hook 321 is reset and the hook-shaped part extends into the previous through hole of the product; the upper die holder 1 and the lower die holder 2 are repeatedly operated, the feeding hook 321 is reciprocated, the automatic feeding work of the product strip is completed, manual operation is not needed, the work efficiency is improved, and personal safety is prevented.
