Description

Technical Field

[0001] The invention relates to a forming machine, in particular to a forming machine for a metal hook knife. Background Art

[0002] In the textile, sewing and related industries, metal hook knives are widely used as an important auxiliary tool in the yarn processing process, especially in the scene of accurately cutting the yarn on the yarn wheel. Due to their unique shape and function, these tools are usually called knotting knives, yarn cutting knives or thread cutting hook knives. They play an indispensable role in improving production efficiency and ensuring yarn quality. At present, most of the metal hook knives circulating on the market are still made by traditional hand-made methods. This production method relies on experienced craftsmen to complete a series of complex process steps such as forging, grinding, and shaping. The advantage of hand-made is that the shape, angle and sharpness of the knife can be flexibly adjusted 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 hand-made method has gradually exposed its limitations: 1. Low production efficiency: The manual process is cumbersome and time-consuming, and it is difficult to meet the needs of large-scale production; 2. Poor consistency: Since hand-made depends on the skills and experience of craftsmen, there may be large differences in the size, shape and sharpness of knives in different batches or within the same batch, which affects the use effect. 3. High cost: The labor cost of handmade products is high, and as the labor cost increases, the manufacturing cost of the tool also increases. Summary of the invention

DETAILED DESCRIPTION

[0013] like Figure 6 As shown, the metal hook knife B includes a ring portion B1 and a hook portion B2. The fully automatic metal hook knife forming machine is used to make the metal hook knife B of this structure.

[0014] like Figure 1 As shown, the fully automatic metal hook knife forming machine comprises a base 1 and a traction mechanism 2, wherein the traction mechanism 2 is used to pull the metal wire A, which is the material for making the metal hook knife B, forward. Figure 2 As shown, a feed seat 3 is provided in front of the traction mechanism 2, and the feed seat 3 has a feed through hole 30, and the metal wire should pass through the feed through hole 30; Figure 3 As shown, a hook knife forming mold 9 is provided in front of the feed seat 3, and the hook knife forming mold 9 is installed on the machine base 1. As shown in 5, the hook knife forming mold 9 includes a ring forming mold 90 and a hook forming mold 91. The ring forming mold 90 has four ring supporting surfaces (the four surfaces of the column), and the hook forming mold 9 has a hook supporting surface; the rear half of the metal wire A is wound around the ring forming mold 90 to form a ring portion B1, and the front half of the metal wire A is pressed on the hook forming mold 91 to form a hook portion B2.

[0015] In order to form such a metal hook knife B, Figure 3 and Figure 5As shown, a first forming mechanism 4 is provided in front of the feed seat 3, and 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 slidably 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 molding mechanism 5 is provided in front of the first molding mechanism 4, and the second molding mechanism 5 includes a second molding die 51 and a second die base 50. The second molding die 51 is installed on the second die base 50, and the second die base 50 is slidably arranged. The second molding die 51 is located above the hook knife molding die 9; when the first die base 42 slides, the second die base 50 slides downward, driving the second molding die 51 to move downward, pressing the metal wire above the ring molding die 90 and the hook molding die 91. Since the front end of the hook molding 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 lifted up to initially form a bent hook. A third molding mechanism 6 is provided below the first molding mechanism 4. The third molding mechanism 6 includes a third molding die 61 and a third die base 60. The third molding die 61 is mounted on the third die base 60. The third die base 60 is slidably arranged. As shown in Figure 5, the third molding die 61 has a first molding recess 610. After the metal wire A is pressed down by the first molding die 41, the first molding recess 610 of the third molding die 61 presses the metal wire onto the first molding corner of the ring forming die 90. A fourth molding mechanism 7 is provided in front of the third molding mechanism 6. The fourth molding mechanism 7 includes a fourth molding die 71 and a fourth die base 70. The fourth molding die 71 is mounted on the fourth die base 70. The fourth die base 70 is slidably arranged. The fourth molding die 71 has a second molding recess 710. After the third molding die 61 is pressed, the second molding recess 710 of the fourth molding die 71 presses the metal wire onto another molding corner of the ring forming die 90. In this way, the ring portion B1 of the metal hook B is formed.

[0016] like Figure 3 As shown, a fifth forming mechanism 8 is provided in front of the hook forming die 91, and 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 slidably 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 presses 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.

[0017] In order to automatically remove the formed metal hook knife B from the hook knife forming mold 9, a ejection mechanism is installed on the machine base 1, as shown in Figure 5, and the ejection mechanism includes an ejection rod 19 and an ejection driving mechanism (cam structure, cylinder, motor) for driving the ejection rod 19 to move in and out. The ejection rod 19 can push out the metal hook knife B on the hook knife forming mold 9 through the drive of the ejection driving mechanism, thereby completing automatic discharging.

[0018] In order to drive the cutting blade 40 and each die action, such as Figure 3 and Figure 4 As shown, a rotatable first cam 45, a third cam 64, a fourth cam 74 and a 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 disposed 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 disposed in the back cam groove 451 of the first cam 45, so that by driving the first cam 45 to rotate, the first die holder 42 and the second die holder 50 can be driven to slide, the first die holder 42 moves, thereby driving the cutting knife 40 and the first molding die 41 to move, and the second die holder 50 moves, thereby driving the second molding die 51. The third die holder 60 is connected to the third roller 63, and the third roller 63 is slidably disposed in the third cam groove 640 of the third cam 64, so that by driving the third cam 64, the third die holder 60 can be driven to move, thereby driving the third molding die 61. The fourth die base 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, so that by driving the fourth cam 74 to rotate, the fourth die base 70 can be driven to move, thereby driving the fourth molding die 71 to move; the fifth die base 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, so that by driving the fifth cam 84 to rotate, the fifth die base 80 can be driven to move, thereby driving the fifth molding die 81 to move.

[0019] In order to drive all cams to rotate when only one forming power source 88 is used, as shown in Figure 4, the present invention rotatably mounts the first cam 45 on the machine base 1 through the first wheel shaft 46, and the first sprocket 47 is installed 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 the third sprocket 66 is installed 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 the fourth sprocket 76 is installed 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 the fifth sprocket 86 is installed 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 transmission-connected to the forming power source 88. Through this structure, the forming power source 88 drives the chain 18 to drive all the sprockets to rotate, which can drive all the cams to rotate. That is to say, when only one forming power source 88 is used, the cutting and all molding actions can be completed, thereby greatly saving costs.

[0020] As shown in FIG. 2 , the traction mechanism 2 of the present invention 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 an upper wheel shaft 210, which is rotatably mounted on the machine base 1. The lower traction wheel 21 is mounted on a lower wheel shaft 200, which is rotatably mounted on the machine base 1. A lower gear 201 is mounted on the lower wheel shaft 200, an upper gear 211 is mounted on the upper wheel shaft 210, and the upper gear 211 is meshed with the lower gear 201. The lower wheel shaft 200 or the upper wheel shaft 210 is transmission-connected with the traction power source 22. Driven by the traction power source 22, the upper traction wheel 21 and the lower traction wheel 20 rotate synchronously, thereby pulling the metal wire A to move forward.

[0021] In order to correct the position of the metal wire A in the horizontal direction and always keep it straight, Figure 2 As shown, a horizontal correction mechanism 10 is provided behind the traction mechanism 2, and 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, and the plurality of horizontal correction wheels 101 are divided into two rows, and the horizontal correction wheels 101 in the two rows are staggered front and back. The metal wire A passes between the two rows of horizontal correction wheels 101, and since the two rows of horizontal correction wheels 101 are staggered front and back, the metal wire A can be corrected in the horizontal direction.

[0022] Similarly, in order to correct the position of the metal wire A in the vertical direction and always keep it straight, Figure 2As shown, a vertical correction mechanism 11 is provided at the rear of the traction mechanism 2. The vertical correction mechanism 11 includes a vertical correction seat 110 and a plurality of vertical correction wheels 111. The plurality of vertical correction wheels 111 are vertically mounted on the vertical correction seat 110. The plurality of vertical correction wheels 111 are divided into two rows, one above the other, and the two rows of vertical correction wheels 111 are staggered front and back. The metal wire A passes between the two rows of vertical correction wheels 101. Since the two rows of horizontal correction wheels 101 are staggered front and back, the metal wire A can be corrected in the vertical direction.
