[0002] In the textile, sewing and related industries, the metal hook knife, as an important auxiliary tool, is widely used in the process of yarn processing, especially in the scenario of precisely cutting yarn on a yarn wheel. Due to its unique shape and function, such tools are usually called knotting knives, yarn cutting knives or wire cutting hook knives, and they play an indispensable role in improving production efficiency and ensuring yarn quality. At present, the vast majority of metal hook knives on the market still adopt the traditional manual manufacturing method. This manufacturing method relies on experienced craftsmen to complete through a series of complex technological steps such as forging, grinding and shaping. The advantage of manual manufacturing is that it can flexibly adjust the shape, angle and sharpness of the tool to meet the cutting requirements of different yarn materials and yarn wheel structures. However, with the rapid development of industrialization and the popularization of automation technology, the traditional manual manufacturing method gradually exposes its limitations: 1. Low production efficiency: The manual manufacturing process is cumbersome and time-consuming, making it difficult to meet the needs of large-scale production; 2. Poor consistency: Since manual manufacturing relies on the skills and experience of craftsmen, there may be significant differences in the size, shape and sharpness of the knives in different batches or within the same batch, affecting the use effect. 3.

[0018] As [[ID=3D]] Figure 6 shown, the metal hook knife B includes a ring part B1 and a hook part B2. This fully automatic metal hook knife forming machine is used to manufacture the metal hook knife B with this structure.

[0019] As Figure 1 shown, this fully automatic metal hook knife forming machine includes a base 1 and a traction mechanism 2. The traction mechanism 2 is used to pull the metal wire A, which is the material for making the metal hook knife B, forward. As Figure 2 shown, a feeding base 3 is provided in front of the traction mechanism 2. The feeding base 3 has a feeding through hole 30, and the metal wire passes through the feeding through hole 30; As Figure 3 shown, a hook knife forming die 9 is provided in front of the feeding base 3. The hook knife forming die 9 is installed on the base 1. As shown in Fig. 5, the hook knife forming die 9 includes a ring part forming die 90 and a hook part forming die 91. The ring part forming die 90 has four ring part supporting surfaces (the four surfaces of the pillar), and the hook part forming die 91 has one hook part supporting surface; The rear half of the metal wire A is wound around the ring part forming die 90 to form the ring part B1, and the front half of the metal wire A is pressed on the hook part forming die 91 to form the hook part B2.

[0020] In order to form such a metal hook knife B, as Figure 3 and Figure 5As shown, a first forming mechanism 4 is provided in front of the feed seat 3. The first forming mechanism 4 includes a cutting knife 40, a first forming die 41 and a first die seat 42. The cutting knife 40 and the first forming die 41 are installed on the first die seat 42, and the first die seat 42 is slidingly arranged. During forming, driven by a power source, the first die seat 42 slides, so that the cutting knife 40 cooperates with the feed seat 3 to cut a section of the metal wire A. At the same time, the first forming die 41 moves downward to bend the metal wire A onto the ring forming die 90. A second forming mechanism 5 is provided in front of the first forming mechanism 4, and the second forming mechanism 5 includes a second forming die 51 and a second die base 50. The second forming die 51 is installed on the second die base 50, and the second die base 50 is slidingly arranged. The second forming die 51 is located above the hook knife forming die 9; when the first die base 42 slides, the second die base 50 slides downward, driving the second forming die 51 to move downward, pressing the metal wire above the ring forming die 90 and the hook forming die 91. Since the front end of the hook forming die 91 is provided with a step portion 92 higher than the hook support surface, under the action of the step portion 92, the front end of the metal wire A will be tilted upward to initially form a bent hook. Below the first forming mechanism 4 is a third forming mechanism 6, which includes a third forming die 61 and a third die holder 60. The third forming die 61 is mounted on the third die holder 60, which is slidable. As shown in Figure 5, the third forming die 61 has a first forming notch 610. After the metal wire A is pressed down by the first forming die 41, the first forming notch 610 of the third forming die 61 presses the metal wire against the first forming corner of the ring forming die 90. A fourth forming mechanism 7 is provided in front of the third forming mechanism 6. The fourth forming mechanism 7 includes a fourth forming die 71 and a fourth die holder 70. The fourth forming die 71 is mounted on the fourth die holder 70, which is slidable. The fourth forming die 71 has a second forming notch 710. After the third forming die 61 completes the pressing, the second forming notch 710 of the fourth forming die 71 presses the metal wire against the other forming corner of the ring forming die 90. In this way, the ring portion B1 of the metal hook B is formed.

[0021] like Figure 3 As shown, a fifth forming mechanism 8 is provided in front of the hook forming die 91. The fifth forming mechanism 8 includes a fifth forming die 81 and a fifth die base 80. The fifth forming die 81 is installed on the fifth die base 80, and the fifth die base 80 is slidingly arranged. The front end of the hook forming die 91 is provided with a step portion 92 higher than the hook support surface. When the front end of the metal wire A is tilted upward, the fifth forming die 81 moves above the step portion and bends the front end of the metal wire A upward again, forming a 90° angle at the front end of the metal wire A, thereby completing the forming work of the metal hook knife B.

[0022] In order to automatically remove the formed metal cutter B from the cutter forming die 9, a blanking mechanism is installed on the machine base 1. As shown in Figure 5, the blanking mechanism includes a blanking rod 19 and a blanking drive mechanism (cam structure, cylinder, motor, etc.) for driving the blanking rod 19 to move in and out. Through the drive of the blanking drive mechanism, the blanking rod 19 can push out the metal cutter B on the cutter forming die 9, thus completing automatic discharging.

[0023] In order to drive the cutting knife 40 and each pressing die to act, as Figure 3 and Figure 4 shown, a rotatable first cam 45, third cam 64, fourth cam 74 and fifth cam 84 are installed on the machine base 1; the first die holder 42 is connected to the first roller 44, and the first roller 44 is slidably arranged in the front cam groove 450 of the first cam 45; the second die holder 50 is connected to the second roller 53, and the second roller 53 is slidably arranged in the rear cam groove 451 of the first cam 45. Thus, by driving the first cam 45 to rotate, the first die holder 42 and the second die holder 50 can be driven to slide. When the first die holder 42 moves, the cutting knife 40 and the first forming pressing die 41 are driven to act. When the second die holder 50 moves, the second forming pressing die 51 is driven to act. The third die holder 60 is connected to the third roller 63, and the third roller 63 is slidably arranged in the third cam groove 640 of the third cam 64. Thus, by driving the third cam 64, the third die holder 60 can be driven to move, so as to drive the third forming pressing die 61 to act. The fourth die holder 70 is connected to the fourth roller 73, and the fourth roller 73 is slidably arranged in the fourth cam groove 740 of the fourth cam 74. Thus, by driving the fourth cam 74 to rotate, the fourth die holder 70 can be driven to move, so as to drive the fourth forming pressing die 71 to move; the fifth die holder 80 is connected to the fifth roller 83, and the fifth roller 83 is slidably arranged in the fifth cam groove 840 of the fifth cam 84. Thus, by driving the fifth cam 84 to rotate, the fifth die holder 80 can be driven to move, so as to drive the fifth forming pressing die 81 to move.

[0024] In order to drive all the cams to rotate when only one forming power source 88 is adopted, as shown in Figure 4, in the present utility model, the first cam 45 is rotatably mounted on the machine base 1 through the first wheel shaft 46, and a first sprocket 47 is mounted on the first wheel shaft 46; the third cam 64 is rotatably mounted on the machine base 1 through the third wheel shaft 65, and a third sprocket 66 is mounted on the third wheel shaft 65; the fourth cam 74 is rotatably mounted on the machine base 1 through the fourth wheel shaft 75, and a fourth sprocket 76 is mounted on the fourth wheel shaft 75; the fifth cam 84 is rotatably mounted on the machine base 1 through the fifth wheel shaft 85, and a fifth sprocket 86 is mounted on the fifth wheel shaft 85; a chain 18 is wound around the first sprocket 47, the third sprocket 66, the fourth sprocket 76, and the fifth sprocket 86, and the chain 18 is in transmission connection with the forming power source 88. Through this structure, the forming power source 88 drives the chain 18 to drive all the sprockets to rotate, and then can drive all the cams to rotate. That is to say, when only one forming power source 88 is adopted, the cutting and all the die pressing actions can be completed, thus greatly saving costs.

[0025] As shown in Figure 2, the traction mechanism 2 of the present utility model includes an upper traction wheel 21, a lower traction wheel 20, and a traction power source 22. The upper traction wheel 21 is mounted on the upper wheel shaft 210, and the upper wheel shaft 210 is rotatably mounted on the machine base 1. The lower traction wheel 20 is mounted on the lower wheel shaft 200, and the lower wheel shaft 200 is rotatably mounted on the machine base 1. A lower gear 201 is mounted on the lower wheel shaft 200, and an upper gear 211 is mounted on the upper wheel shaft 210. The upper gear 211 meshes with the lower gear 201, and the lower wheel shaft 200 or the upper wheel shaft 210 is in transmission connection with the traction power source 22. Through the drive of the traction power source 22, the upper traction wheel 21 and the lower traction wheel 20 rotate synchronously, thereby pulling the wire A forward.

[0026] In order to correct the position of the wire A in the horizontal direction and always keep it straight, as Figure 2 shown, a horizontal correction mechanism 10 is provided behind the traction mechanism 2. The horizontal correction mechanism 10 includes a horizontal correction seat 100 and a plurality of horizontal correction wheels 101. The plurality of horizontal correction wheels 101 are horizontally mounted on the horizontal correction seat 100. The plurality of horizontal correction wheels 101 are divided into left and right rows, and the horizontal correction wheels 101 in the two rows are staggered front and back. The wire A passes between the two rows of horizontal correction wheels 101. Since the horizontal correction wheels 101 in the two rows are staggered front and back, the wire A can be corrected in the horizontal direction.

[0027] Similarly, in order to correct the position of the wire A in the vertical direction and always keep it straight, as Figure 2As shown in the figure, a vertical correction mechanism 11 is provided behind the traction mechanism 2. The vertical correction mechanism 11 includes a vertical correction base 110 and a number of vertical correction wheels 111. The number of vertical correction wheels 111 are vertically installed on the vertical correction base 110. The number of vertical correction wheels 111 are divided into upper and lower rows, and the vertical correction wheels 111 in the two rows are staggered front and back. The wire A passes between the two rows of vertical correction wheels 101. Since the horizontal correction wheels 101 in the two rows are staggered front and back, the wire A can be corrected in the vertical direction in this way.
