[0002] The lead sinker, also known as the lead weight, is an indispensable auxiliary fishing tool in the fishing group. The weight is 1 gram, 10 grams, 50 grams or even several hundred grams. Its role in fishing is that when casting a long distance, the angler uses its weight to throw the hook bait into the fishing spot in front, and after entering the water, it relies on its weight to balance the fishing group; when the fish bites the hook, the hook can use the weight of the lead sinker to pierce the fish lip to make the fish hooked. The lead sinker is generally composed of a lead core and a lead sheet wrapped around the outside of the lead core. The lead sheet is in a flat state when it is not processed, and its connection with the lead core needs to be bent.

DETAILED DESCRIPTION

[0020] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] Reference Figure 1-3 , is a lead sheet bending device disclosed in the utility model, comprising a vertically placed fixed bracket 1, on which a moving bracket 3 and a first power member 4 are arranged, and on which a bending mechanism 5 is arranged, and the first power member 4 drives the moving bracket 3 to rise and fall on the fixed bracket 1 through a sliding member 2, so that the bending mechanism 5 performs a bending operation on one end of the lead sheet in a flat state from the bottom of the lead sheet from bottom to top; the bending mechanism 5 comprises a bending assembly and a second power member 6, and the bending mechanism 5 comprises two symmetrically arranged bending arms 51, and the bending arms 51 are rotatably connected to the moving bracket 3, the second power member 6 drives the bending arm 51 to rotate and fold the lead sheet, so that one end of the bent lead sheet is rolled and wrapped around the outside of the lead core. When the lead sheet is placed at the corresponding position of the bending mechanism 5, one end of the lead sheet is against the outer wall of the bending arm 51. When the first power member 4 is operated to drive the moving frame 3 to rise, the bending mechanism 5 is also raised accordingly, so that one end of the flatly laid lead sheet is vertically bent 90°. Then the second power member 6 is operated again to drive the bending arm 51 to rotate, and the bending arm 51 is pushed forward along the vertical part of the lead sheet to bend the vertical part onto the lead core, and the bending of the lead sheet is completed through two steps.

[0023] The end of the bending arm 51 corresponding to the lead sheet is an arc-shaped structure, and the curvature of the arc-shaped structure decreases from bottom to top, so that the end of the lead sheet first abuts against the position with a smaller curvature above the bending arm 51. As the movable frame 3 rises, the position with a larger curvature of the bending arm 51 moves upward to bend the lead sheet abutting therewith; a support platform 52 is provided at the bottom of the bending arm 51, and the support platform 52 is fixed at one end of the movable frame 3, and the support platform 52 is supported at the bottom of the bending arm 51.

[0024] The movable frame 3 includes a horizontal platform 32 and a vertical plate 31 fixedly connected to the horizontal platform 32; the sliding member 2 includes a slider installed on the vertical plate 31, the slider is slidably connected to the slide rail, and the slide rail is installed on the fixed bracket 1; the first power member 4 includes a first cylinder, the first cylinder is arranged on the fixed bracket 1, the telescopic end of the first cylinder is connected to the vertical plate 31, the telescopic end of the first cylinder causes the vertical plate 31 to slide up and down on the fixed bracket 1 through the slider and the slide rail, and the horizontal platform 32 fixedly connected to the vertical plate 31 also slides up and down accordingly.

[0025] The second power member 6 is installed on the horizontal platform 32, and the second power member 6 includes a second cylinder 61 and a transmission member. The telescopic end of the second cylinder 61 is connected to the transmission member, and the transmission member is connected to the bending arm 51; the transmission member includes a gear 63 and a rack 62 meshed with the gear 63, and the rack 62 is slidably connected to the horizontal platform 32, and the rack 62 is connected to the telescopic end of the second cylinder 61. As the second cylinder 61 is extended and retracted, the rack 62 slides horizontally, thereby driving the gear 63 meshed with it to rotate.

[0026] The gear 63 is coaxially connected to the connecting shaft 53, and both ends of the connecting shaft 53 are connected to the two bending arms 51. The connecting shaft 53 passes through the horizontal table 32 and is connected to the two bending arms 51. The connecting shaft 53 is rotatably connected to the horizontal table 32. When the second cylinder 61 extends and drives the gear 63 to rotate, the gear 63 drives the connecting shaft 53 to rotate, so that the bending arm 51 rotates toward the position of the lead sheet in a vertical state. The bending arm 51 rotates forward to push the vertical end of the lead sheet. After the lead sheet is bent, the second cylinder 61 contracts to rotate and recover the bending arm 51. Along the arc-shaped motion trajectory of the bending arm 51, the lead sheet can be bent and wrapped around the outside of the lead core.

[0027] The implementation principle of the utility model is: the lead sheet is spread flat on the processing table, one end of which is abutted on the bending arm 51, the lead core is placed on the lead sheet, the first cylinder is extended to drive the movable frame 3 to rise, the bending arm 51 first performs a vertical bending operation on the lead sheet, and then the second cylinder 61 is extended to make the bending arm 51 rotate forward to further bend the vertical part of the lead sheet on the lead core.
