[0066] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0067] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0068] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0069] like Figure 1 and Figure 2 and Figure 3 As shown, it includes a base 1, a feeding assembly 2, a clamping assembly 3, an impact assembly 4 and a power assembly 5. The power assembly 5 is rotatably set on the base 1. The power assembly 5 provides power to the feeding assembly 2, the clamping assembly 3 and the impact assembly 4. The feeding assembly 2, the clamping assembly 3 and the impact assembly 4 are cooperatively set on the base 1.

[0070] The feeding assembly 2 includes a first slider 21, a rotating rod 22 and a first fixed seat 25. The first slider 21 is slidably set on the base 1, the rotating rod 22 is rotatably set on the base 1, and the middle position of the rotating rod 22 is rotatably set on the base 1. A guide rod 96 is also provided on the first fixed seat 25. The first slider 21 is sleeved on the guide rod 96. The first slider 21 can slide on the guide rod 96. The first slider 21 abuts against the length end of the rotating rod 22. When the rotating rod 22 rotates, the rotating rod 22 pushes the first slider 21 to move. A first clamping member 9 is provided on the first slider 21. The first clamping member 9 has two states of clamping and releasing the wire 7. The wire passes through the first clamping member 9. When the first slider 21 drives the first clamping member 9 to move, the first clamping member 9 drives the wire to move together. A first elastic member 26 is provided between the first slider 21 and the first fixed seat 25.

[0071] After the rotating rod 22 pushes the first slider 21 to move the set distance, the first elastic member 26 is compressed between the first slider 21 and the first fixed seat 25, and the rotating rod 22 is about to reset. At this time, the first slider 21 is also reset under the action of the first elastic member 26. At the same time, the first clamping member 9 is reset, and the first clamping member 9 releases the wire. Then the rotating rod 22 rotates, and then pushes the first slider 21 to move the set distance, and the cycle continues.

[0072] The clamping assembly 3 includes a first slide 31, a conversion block 32, a first clamp 33 and a second clamp 34. The first slide 31 and the first clamp 33 are slidably set on the base 1, the conversion block 32 is rotatably set on the base 1, and the second clamp 34 is located on the moving path of the first slide 31. The first slide 31 can abut against the second clamp 34 and can also stay away from the second clamp 34.

[0073] The two ends of the conversion block 32 respectively abut against the first slide 31 and the first clamping block 33, and an angle is formed between the first slide 31 and the first clamping block 33. When the first slide 31 drives the conversion block 32 to rotate, the conversion block 32 drives the first clamping block 33 to move. The conversion block 32 is a fan-shaped body, and the first slide 31 and the first clamping block 33 respectively abut against the two side surfaces of the conversion block 32 in the rotation direction.

[0074] The two ends of the first slide 31 respectively abut against the conversion block 32 and the outer periphery of the first rotating wheel 51, and the outer periphery of the first rotating wheel 51 is provided with a clamping area 511, a loosening area 512 and a material withdrawal area 513. Since the heights of the three are different, when the first rotating wheel 51 rotates, the end of the first slide 31 in the length direction abuts against the outer periphery of the first rotating wheel 51, and the first rotating wheel 51 has a pushing effect on the first slide 31, thereby driving the first clamping block 33 to move through the conversion block 32.

[0075] When the first slide 31 abuts against the clamping area 511, the first rotating wheel 51 indirectly drives the first clamping block 33 to abut the second clamping block 34. When the first slide 31 abuts against the release area 512, the clamping spring 35 indirectly drives the first clamping block 33 to reset, and the first clamping block 33 reversely drives the conversion block 32 to reset, and then indirectly drives the first slide 31 to reset. When the first slide 31 abuts against the material stripping area 513, the clamping spring 35 drives the first clamping block 33 to move the farthest distance, that is, the first clamping block 33 and the second clamping block 34 are farthest apart, and the space between the first clamping block 33 and the second clamping block 34 is the largest.

[0076] The impact assembly 4 includes a formed impact head 41 and a second slide 42. The second slide 42 is slidably set on the base 1. The formed impact head 41 is set on the second slide 42. The length end of the second slide 42 is overlapped on the second rotating wheel 52. The formed impact head 41 and the second rotating wheel 52 are respectively located at both ends of the second slide 42. When the second rotating wheel 52 rotates, it can drive the second slide 42 to move, and the second slide 42 drives the formed impact head 41 to move.

[0077] The formed collision head 41 is coaxial with the first clamping member 9, and the abutment portion of the first clamping block 33 and the second clamping block 34 is located between the formed collision head 41 and the first clamping member 9. The first clamping member 9 sends the wire 7 between the first clamping block 33 and the second clamping block 34, and then the first clamping block 33 and the second clamping block 34 jointly clamp the wire 7, and then the second slide 42 drives the formed collision head 41 to hit the front end of the wire 7, making the front end of the wire 7 thicker.

[0078] The feeding assembly 2 also includes a power rod 23, and the two ends of the rotating rod 22 respectively abut the power rod 23 and the first slider 21. The power assembly 5 also includes a first cam 53. The length direction end of the power rod 23 overlaps the outer periphery of the first cam 53, so that the rotating rod 22 and the first cam 53 are respectively arranged on both sides of the power rod 23. When the first cam 53 rotates, when the length direction end of the power rod 23 overlaps the protruding part of the first cam 53, the power rod 23 can push the rotating rod 22 to rotate, and then indirectly drive the first slider 21 to move. When the length direction end of the power rod 23 is away from the protruding part of the first cam 53, under the action of the first elastic member 26, the rotating rod 22 is indirectly driven to rotate and reset, and the length direction end of the power rod 23 overlaps the non-protruding part of the first cam 53.

[0079] A first guide block 11 and a second guide block 12 are provided on the base 1, and a power-assisting rod 23 is slidably provided on the first guide block 11 and the second guide block 12. A feed spring 24 is also sleeved on the power-assisting rod 23, and the feed spring 24 is located between the first guide block 11 and the second guide block 12. When the first cam 53 drives the power-assisting rod 23 to move, and the power-assisting rod 23 moves in the direction of the first guide block 11, the feed spring 24 abuts against the first guide block 11. When the lengthwise end of the power-assisting rod 23 overlaps the non-protruding part of the first cam 53, the feed spring 24 drives the power-assisting rod 23 to reset to prevent the power-assisting rod 23 from squeezing the first cam 53. During the retraction of the power-assisting rod 23, the feed spring 24 abuts against the second guide block 12. When the power-assisting rod 23 moves, the first guide block 11 and the second guide block 12 can also play a guiding role.

[0080] A pushing assembly 6 and a sliding hole 13 are provided on the base 1. The pushing assembly 6 includes a connecting rod 61, a second slider 62 and a second fixed seat 64. The second slider 62 and the first slider 21 are arranged across both sides of the sliding hole 13, and the second slider 62 and the first slider 21 can move above the sliding hole 13. The first fixed seat 25 and the second fixed seat 64 are respectively located at both ends of the length direction of the sliding hole 13. The guide rod 96 is sleeved on the second slider 62 and the second fixed seat 64. The second slider 62 is slidably set on the guide rod 96. The first slider 21 is located between the first fixed seat 25 and the second slider 62. The second slider 62 is located between the first slider 21 and the second fixed seat 64. The connecting rod 61 passes through the sliding hole 13, and the end portion of the connecting rod 61 in the length direction is connected to the bottom of the second slider 62. The connecting rod 61 can drive the second slider 62 to move. A second clamping member 10 is provided on the second slider 62. The second clamping member 10 has the same shape and structure as the first clamping member 9.

[0081] In the initial state, the wire 7 first passes through the first clamping member 9 and the second clamping member 10, so that the front end of the wire 7 passes through the first clamping block 33 and the second clamping block 34. The length of the wire 7 passing through is set, and then under the rotation of the second rotating wheel 52, the second slide 42 drives the forming collision head 41 to move, and the forming collision head 41 hits the front end of the wire 7. After the collision, the front end of the wire 7 becomes thicker, and the length of the entire wire 7 becomes shorter.

[0082] After the formed ram 41 hits once, the length of the impact of the formed ram 41 is different according to the different heights of the protrusions 521, so the protrusion 54 on the first cam 53, the protrusion 54 drives the power rod 23 to move, the power rod 23 drives the rotating rod 22 to rotate, the rotating rod 22 drives the first slider 21 to move the set length, the first clamping member 9 clamps the wire 7 to move the set length, the length of the wire 7 moving toward the formed ram 41 matches the protrusions 521 of different heights, and the formed ram 41 hits the front end of the wire 7 each time, forming a wire 7 head of different thickness.

[0083] In addition, after the front end of the wire 7 is impacted and formed, the wire 7 will be cut into a section, and the subsequent wire 7 needs to be conveyed forward, which is the next cycle. The connecting rod 61 drives the second slider 62 to move, and the power rod 23 drives the rotating rod 22 to rotate. The rotating rod 22 drives the first slider 21 to move the set length. The first clamping member 9 clamps the wire 7 to move the set length. The length and speed of the movement of the second slider 62 are consistent with the first slider 21, so the first clamping member 9 and the second clamping member 10 can clamp the wire 7 at the same time, and the moving distance is also the same. This is the position of the wire 7 in the initial state. Then the forming collision head 41 hits, and after the first clamping member 9 retracts, the wire 7 of the set length is fed again, and the second clamping member 10 releases the wire 7 and slowly resets.

[0084] The power assembly 5 also includes a second cam 56, which is arranged on the rotating shaft 50. A cross-rod 14 is also provided on the base 1. The rotating shaft 50 is located at the bottom of the cross-rod 14. A connecting plate 63 is rotatably provided on the cross-rod 14, and a coupling wheel 65 is rotatably provided on the connecting plate 63. The coupling wheel 65 is coupled to the outer periphery of the second cam 56. When the second cam 56 rotates, it drives the coupling wheel 65 to rotate, so the second cam 56 indirectly drives the connecting plate 63 to swing by rotation. A limiting spring 66 is provided on the connecting plate 63, and the two ends of the limiting spring 66 are respectively connected to the connecting plate 63 and the base 1.

[0085] The connecting rod 61 is connected to the bottom of the connecting plate 63, so that when the second cam 56 rotates, the protruding part of the second cam 56 indirectly drives the connecting plate 63 to move, and the connecting plate 63 moves toward the wall of the base 1. At the same time, the limit spring 66 is compressed, so that the connecting plate 63 drives the connecting rod 61 to move, and the connecting rod 61 drives the second slider 62 to move. After each collision is completed, the formed wire 7 is cut for a section, and the subsequent wire 7 needs to be fed. At this time, the second slider 62 needs to move the set distance. This length is the initial position of the wire 7 at the beginning. As the second cam 56 rotates, the coupling wheel 65 slowly leaves the protruding part of the second cam 56. At the same time, the limit spring 66 drives the connecting plate 63 to reset, and the coupling wheel 65 overlaps the lowest point of the outer periphery of the second cam 56. At this time, the second cam 56 is reset.

[0086] The first clamping block 33 is provided with a first clamping groove 330, and the second clamping block 34 is provided with a second clamping groove 340. The first clamping groove 330 and the second clamping groove 340 are arranged opposite to each other, and the first clamping groove 330 and the second clamping groove 340 are enclosed together for clamping the wire 7. After the front end of the wire 7 is impacted and formed, the formed wire 7 is cut, and the first clamping block 33 and the second clamping block 34 are moved away from each other, the first clamping groove 330 and the second clamping groove 340 are separated, and the cut wire 7 is taken out.

[0087] The first clamping block 33 is provided with a first push strip 331, the first push strip 331 has a first fixing portion 333 and a first pushing portion 335, and the second clamping block 34 is provided with a second push strip 342, the second push strip 342 has a second fixing portion 344 and a second pushing portion 346. The first fixing portion 333 is provided on the first clamping block 33, the first pushing portion 335 overlaps the upper surface of the second clamping block 34, the second fixing portion 344 is provided on the second clamping block 34, and the second pushing portion 346 overlaps the upper surface of the first clamping block 33. When the first clamping block 33 and the second clamping block 34 move away from each other, the cut wire 7 will stay in the first clamping groove 330 or the second clamping groove 340, so the first clamping block 33 drives the first pushing portion 335 to move, and the first pushing portion 335 scrapes off the wire 7 staying in the second clamping groove 340, and the second clamping block 34 drives the second pushing portion 346 to move, and the second pushing portion 346 scrapes off the wire 7 staying in the first clamping groove 330.

[0088] like Figure 4 and Figure 5 and Figure 6 As shown, the power assembly 5 includes a rotating shaft 50, a first rotating wheel 51 and a second rotating wheel 52. The rotating shaft 50 is rotatably set on the base 1, and the first rotating wheel 51 and the second rotating wheel 52 are set on the rotating shaft 50. The rotating shaft 50 rotates, driving the first rotating wheel 51 and the second rotating wheel 52 to rotate together.

[0089] The first rotating wheel 51 has an outwardly protruding clamping area 511 and an inwardly recessed releasing area 512 on its outer periphery. The clamping area 511 and the releasing area 512 are adjacent to each other. The first rotating wheel 51 also has a material withdrawal area 513 on its outer periphery. The depth of the material withdrawal area 513 is deeper than that of the releasing area 512. The material withdrawal area 513 has clamping areas 511 at both ends. The releasing area 512 and the material withdrawal area 513 are equivalent to grooves.

[0090] like Figure 7 and Figure 8 As shown, a plurality of protrusions 54 are provided on the outer periphery of the first cam 53, and the plurality of protrusions 54 are distributed on the first side of the first cam 53, and a curved groove 55 is formed between adjacent protrusions 54, and the position of the curved groove 55 is higher than the second side of the first cam 53. When the first cam 53 rotates, the end portion of the power-assisting rod 23 in the length direction overlaps on the first side of the first cam 53, that is, overlaps on the protrusion 54 or the curved groove 55, and the position of the protrusion 54 is higher than the curved groove 55. In this way, the protrusion 54 can drive the power-assisting rod 23 to move, and can also, under the action of the feeding spring 24, make the end portion of the power-assisting rod 23 in the length direction overlap in the curved groove 55, so as to realize the reset of the power-assisting rod 23, while the first cam 53 continues to rotate. The end of the assist rod 23 in the longitudinal direction is overlapped on the second side of the first cam 53, and the position of the curved groove 55 is higher than the second side of the first cam 53. That is, under the action of the feeding spring 24, the assist rod 23 retracts more, and then the end of the assist rod 23 in the longitudinal direction slowly overlaps on the protrusion 54 again, indirectly driving the first clamping member 9 to feed the wire 7. The first side and the second side of the first cam 53 are connected end to end.

[0091] When the auxiliary rod 23 overlaps the second side of the first cam 53 at the end in the length direction, the first clamping member 9 loosens the wire 7 at this time, and the auxiliary rod 23 indirectly drives the first slider 21 to move backward, and the first clamping member 9 is away from the front end of the wire 7, and the front end of the wire 7 is to be impacted and formed.

[0092] like Figure 9 and Figure 10As shown, the outer periphery of the second rotating wheel 52 has a protruding point 521 protruding outward and a groove 522 recessed inward, and the protruding point 521 and the groove 522 are arranged adjacent to each other. When the end of the second slide plate 42 in the longitudinal direction abuts against the protruding point 521, the second slide plate 42 drives the formed collision head 41 to hit the front end of the wire 7. At this time, the collision stroke of the formed collision head 41 is the farthest. When the end of the second slide plate 42 in the longitudinal direction abuts against the groove 522, the second slide plate 42 drives the formed collision head 41 to reset. The outer periphery of the second rotating wheel 52 is also provided with a retraction area 523. The retraction area 523 has protruding points 521 at both ends. The depth of the retraction area 523 is deeper than the depth of the groove 522. When the end of the second slide plate 42 overlaps the retraction area 523, the second slide plate 42 drives the formed collision head 41 to retract. At this time, the formed collision head 41 is farthest away from the front end of the wire 7.

[0093] Multiple protrusions 521 are distributed on the outer circumference of the second rotating wheel 52, and the height of the protrusions 521 on both sides is higher than the height of the protrusion 521 in the middle, so that the end of the second skateboard 4 overlaps the protrusions 521 at different heights, and the impact stroke of the formed impact head 41 is different. The higher the protrusion 521, the longer the impact stroke of the formed impact head 41. The impact assembly 4 also includes an impact spring 43, and the two ends of the impact spring 43 are respectively connected to the second skateboard 42 and the base 1, so that when the second skateboard 42 retracts, it retracts under the action of the impact spring 43.

[0094] Furthermore, a travel block 44 is provided on the second slide 42, and a blocking plate 45 is also provided on the base 1. The blocking plate 45 spans over the second slide 42, and both ends of the impact spring 43 are respectively abutted against the travel block 44 and the blocking plate 45. The blocking plate 45 is located in the moving direction of the travel block 44. When the travel block 44 approaches the blocking plate 45, the impact spring 43 is compressed. When the second slide 42 docks the groove 522 and the retraction area 523, the impact spring 43 has a reaction force on the travel block 44, so that the second slide 42 is reset.

[0095] like Figure 11 and Figure 12 As shown, the power assembly 5 also includes a third cam 57, which is arranged on the rotating shaft 50. The second cam 56 has a center hole 500. The position of the rotating shaft 50 in the center hole 500 is adjustable. When the rotating shaft 50 is at different positions in the center hole 500, the third cam 57 has different centers, so that the third cam 57 can rotate with different radius lengths.

[0096] A slot 58 is provided on the third cam 57, a ridge 59 is provided on the second cam 56, and the ridge 59 is engaged in the slot 58. A positioning hole 560 is provided on the second cam 56, and a fixing hole 570 is provided on the third cam 57. The extension direction of the fixing hole 570 is consistent with the extension direction of the center hole 500, and the positioning hole 560 and the fixing hole 570 are connected by screws.

[0097] like Figure 13 and Figure 14 and Figure 15 As shown, the first clamping member 9 includes a catheter 91 and a sleeve 92 , the catheter 91 and the sleeve 92 are connected by threads, the wire 7 passes through the catheter 91 and the sleeve 92 , and the catheter 91 and the sleeve 92 are connected.

[0098] The inside of the catheter 91 has a truncated cone-shaped cavity 911 and a cavity 912. The truncated cone-shaped cavity 911 becomes smaller as it extends. The truncated cone-shaped cavity 911 and the cavity 912 are connected to each other. A traction tube 93 is movably arranged inside the truncated cone-shaped cavity 911 and the cavity 912. The wire 7 is located in the traction tube 93. The traction tube 93 includes a hollow truncated cone 931 and a tube body 932. The truncated cone 931 is connected to the tube body 932. The wire 7 is located in the truncated cone 931 and the tube body 932.

[0099] The cone 931 is located in the cone-shaped cavity 911. The shape of the cone 931 matches the shape of the cone-shaped cavity 911. The tube body 932 is located in the cavity 912. The wire 7 enters from the entrance end of the cone-shaped cavity 911 and then enters from the entrance end of the cone 931. The cone-shaped cavity 911 becomes smaller as it extends toward the entrance end, and the cone 931 becomes smaller as it extends toward the entrance end.

[0100] A plurality of circular holes 933 are provided on the truncated cone 931, and the plurality of circular holes 933 are located on the same circumference. A ball 94 is movably provided on each circular hole 933, and the wire 7 passes through the center of the plurality of ball 94. When the wire 97 needs to be delivered, the catheter 91 is pushed first, and the catheter 91 moves toward the direction where the sleeve 92 is located. At this time, the wall of the truncated cone cavity 911 presses the ball 94, and the plurality of ball 94 squeezes toward the wire 7. At this time, the plurality of ball 94 jointly clamps the wire 7 and moves a set distance with the catheter 91, and then the catheter 91 is reset. When the catheter 91 moves back and forth, the force exerted by the inner wall of the catheter 91 on the ball 94 is reduced, and then the plurality of ball 94 releases the wire 7. After reset, the catheter 91 performs the same steps as above.

[0101] The sleeve 92 is connected to the cavity 912, and the sleeve 92 is located on the moving path of the tube body 932. When the catheter 91 moves toward the direction of the sleeve 92, the inner wall of the catheter 91 exerts a force on the ball 94, and the ball 94 pushes the cone 931 and the tube body 932 to move toward the sleeve 92, and the tube body 932 abuts against the front end of the sleeve 92, and then multiple balls 94 jointly clamp the wire 7, and the balls 94 roll in contact with the wall of the cone-shaped cavity 911.

[0102] The external thread of the sleeve 92 is engaged with the internal thread of the catheter 91 . The sleeve 92 extends into the catheter 91 , that is, into the cavity 912 . The sleeve 92 blocks and limits the tube body 932 .

[0103] Furthermore, the cross-sectional area of ​​the tube body 932 is smaller than the rear end face of the cone 931, and the tube body 932 extends to the outside of the sleeve 92, which helps the tube body 932 to support the wire 7. The sleeve 92 is located on the moving path of the rear end face of the cone 931. When feeding the wire, the front end of the sleeve 92 blocks the rear end face of the cone 931.

[0104] Furthermore, the traction tube 93 also includes a blocking disk 934, which fits the rear end surface of the truncated cone 931. The blocking disk 934 is sleeved on the tube body 932, and the sleeve 92 is located on the moving path of the blocking disk 934. The blocking disk 934, the truncated cone 931 and the tube body 932 are all integrally formed. When feeding the wire 7, the front end of the sleeve 92 limits the blocking disk 934, and the blocking disk 934 has a protective effect on the truncated cone 931.

[0105] An internal spring 95 is sleeved on the tube body 932, and the two ends of the internal spring 95 respectively abut against the blocking disk 934 and the sleeve 92. When the wire 7 is fed, the internal spring 95 can play a buffering role. When the catheter 91 is reset, the internal spring 95 also plays a buffering role, quickly resetting the traction 93.

[0106] A rotating block 921 is sleeved on the outer periphery of the sleeve 92. The rotating block 921 has a polygonal shape, which is convenient for rotation using external force. At the same time, the rotating block 921 has a limiting effect. When the rotating block 921 abuts the rear end of the catheter 91, the sleeve 92 can no longer enter the cavity 912.

[0107] The outer periphery of the front end of the sleeve 92 has a curved surface 922, which shrinks as it extends, that is, the sleeve 92 becomes smaller as it extends forward. This facilitates the alignment of the sleeve 92 when it is docked with the catheter 91, making it easy to thread the sleeve 92 and the catheter 91 together.

[0108] like Figure 16 and Figure 17 and Figure 18 As shown, the first slider 33 and the second slider 34 are in a separated state, the first slider 33 is provided with a first clamping groove 330 for clamping the product, and the second slider 34 is provided with a second clamping groove 340 for clamping the product, the first clamping groove 330 and the second clamping groove 340 are arranged opposite to each other, the first clamping groove 330 and the second clamping groove 340 can be enclosed together, the wire 7 is located between the first clamping groove 330 and the second clamping groove 340, and the wire 8 is clamped together by the first clamping groove 330 and the second clamping groove 340, and the shape enclosed by the first clamping groove 330 and the second clamping groove 340 matches the shape of the wire 7.

[0109] The first slider 33 and the second slider 34 have two states: one is pressed against each other and the other is moved away from each other. When the wire 7 needs to be impact-formed, the first slider 33 and the second slider 34 approach each other until the first slider 33 and the second slider 34 abut against each other. Because the first clamping groove 330 and the second clamping groove 340 have two states that can be enclosed and separated, when the first slider 33 and the second slider 34 abut against each other, the first slider 33 and the second slider 34 are enclosed together, and the wire 7 is clamped together by the first clamping groove 330 and the second clamping groove 340. After the wire 7 is impact-formed, the first slider 33 and the second slider 34 move away from each other. At this time, the first clamping groove 330 and the second clamping groove 340 are separated from each other.

[0110] Normally, the wire 7 will fall off from between the first clamping groove 330 and the second clamping groove 340 .

[0111] The first clamping block 33 is provided with a first push bar 331 , and the second clamping block 34 is provided with a second push bar 342 . The first push bar 331 has a first fixing portion 333 and a first pushing portion 335 , and the second push bar 342 has a second fixing portion 344 and a second pushing portion 346 .

[0112] The first fixing portion 333 is provided on the first slider 33 and extends toward the second slider 34. The first pushing portion 335 is overlapped on the second slider 34. The second fixing portion 344 is provided on the second slider 34 and extends toward the first slider 33. The second pushing portion 346 is overlapped on the first slider 33.

[0113] The first clamping groove 330 is located on the moving path of the second pushing portion 346, and the second clamping groove 340 is located on the moving path of the first pushing portion 335. When the first slider 33 and the second slider 34 move away from each other, the first push bar 331 and the second push bar 342 approach each other, that is, the first pushing portion 335 and the second pushing portion 346 approach each other. If the wire 7 stays in the first clamping groove 330 or the second clamping groove 340, the corresponding first pushing portion 335 or the second pushing portion 346 pushes the front end of the wire 7, causing the wire 7 to fall out of the first clamping groove 330 or the second clamping groove 340. After the front end of the wire 7 is impact-formed, the front end of the wire 7 is thicker than the back end, that is, the part of the wire 7 located at the front end of the first clamping groove 330 and the second clamping groove 340 becomes thicker.

[0114] The first clamping groove 330 and the second clamping groove 340 both have curved surfaces. The wire 7 in this application is a cylinder, so the first clamping groove 330 and the second clamping groove 340 are both semicircles with curved surfaces, which are combined into a circle to clamp the wire 7.

[0115] The first push strip 331 also includes a first overlapping portion 313 and a first connecting portion 314. The first overlapping portion 313 is connected to the first fixing portion 333, and the first overlapping portion 313 is located at the outer edge of the first slider 33. The first connecting portion 314 is bent and connected to the first overlapping portion 313. The first pushing portion 335 is bent and connected to the first connecting portion 314. The first connecting portion 314 is bent twice, and the position of the first connecting portion 314 is higher than the upper surface of the first slider 33 and the second slider 34.

[0116] In addition, when the first pushing portion 335 encounters resistance, the first pushing portion 335 has a buffering effect because the first pushing portion 335 is connected to the first connecting portion 314 by a bending motion.

[0117] Furthermore, the second push strip 342 also includes a second overlapping portion 323 and a second connecting portion 324, the second overlapping portion 323 is connected to the second fixed portion 344, and the second overlapping portion 323 is located at the outer edge of the second slider 34, the second connecting portion 324 is bent and connected to the second overlapping portion 323, the second connecting portion 324 is connected to the second pushing portion 346, the first pushing portion 335 is flush with the second pushing portion 346, and the second pushing portion 346 is flush with the second connecting portion 324.

[0118] In this application, the first push bar 331 and the second push bar 342 are located on the same side, so when the first push part 335 and the second push part 346 approach each other, the moving path of the second connection part 344 is below the first connection part 314, so that the second connection part 324 and the first connection part 314 move in an offset manner and no collision occurs.

[0119] Because the second connecting portion 324 is connected to the second overlapping portion 323 by bending, the second pushing portion 346 also has a buffering effect when the second pushing portion 346 is subjected to external force.

[0120] like Figure 19 and Figure 20 and Figure 21 As shown, the cutting assembly 8 is arranged on the base 1. When the wire 7 completes the collision, the cutting assembly 8 is used to cut the wire 7 to a set length.

[0121] The cutting assembly 8 includes a fixing seat 831 for fixing, the fixing seat 831 is arranged on the base 1, and a fixing hole 832 with a curved surface is provided on the fixing seat 831. The cutting assembly 8 also includes a first telescopic rod 833, a second telescopic rod 834 and a fan-shaped body 835 with a curved surface. The fan-shaped body 830 is rotatably arranged in the fixing hole 832, and the fan-shaped body 830 can rotate in the fixing hole 832. The first telescopic rod 833 and the second telescopic rod 834 are movably arranged on the fixing seat 831.

[0122] The curved surface of the sector 830 fits the curved surface of the fixing hole 832, and an angle is formed between the first telescopic rod 833 and the second telescopic rod 834. The ends of the first telescopic rod 833 and the second telescopic rod 834 are respectively pressed against the two side surfaces of the sector 830, and the first telescopic rod 833 is pressed downward. The first telescopic rod 833 is pressed against the first side surface in the rotation direction of the sector 830. The first telescopic rod 833 drives the sector 830 to rotate, and the curved surface of the sector 830 slides on the curved surface of the fixing hole 832, so that the direction of rotation of the sector 830 has an arc.

[0123] The second telescopic rod 834 is pressed against the second side surface of the sector 830 in the rotation direction, so that when the sector 830 rotates, the sector 830 drives the second telescopic rod 834 to move linearly in the horizontal direction.

[0124] The first telescopic rod 833 and the second telescopic rod 834 are not on the same straight line, so the downward movement direction of the first telescopic rod 833 is different from the movement direction of the second telescopic rod 834. In this way, the downward pressure of the first telescopic rod 833 is redirected by the fan-shaped body 830 and converted into the same movement direction as the second telescopic rod 834.

[0125] The cutting assembly 8 includes a slider 841 and a tangent tube 842. The slider 841 is slidably arranged on the base 1. The slider 841 is located on the moving path of the second telescopic rod 834. In this way, when the fan-shaped body 830 drives the second telescopic rod 834 to move, the second telescopic rod 834 will press against the slider 841 and drive the slider 841 to move. The tangent tube 842 is arranged on the slider 841. There is an angle between the extension direction of the tangent tube 842 and the moving direction of the slider 841. A wire 7 is passed through the tangent tube 842. When the slider 841 drives the tangent tube 842 to move together, the tangent tube 842 can cut the wire 7 into two sections. The wire 7 passes through the first clamping piece 9, and then the wire 7 passes through the tangent tube 842. There is a gap between the feeding end of the tangent tube 842 and the first clamping piece 9. The discharge of the tangent tube 842 is aligned with the first clamping block 33 and the second clamping block 34. When the first clamping block 33 and the second clamping block 34 jointly clamp the wire 7, the rotating shaft 50 drives the third cam 57 to rotate, and the third cam 57 indirectly drives the tangent tube 842 to move. The wire 7 is cut off at the outlet end of the tangent tube 842, and the first clamping block 33 and the second clamping block 34 clamp part of the wire 7 after the impact is completed.

[0126] The cutting assembly 8 also includes a first clamping plate 835 and a second clamping plate 836, which are respectively arranged on both sides of the fixing seat 831. The first clamping plate 835 and the second clamping plate 836 are connected by screws, and the fixing hole 832 is located between the first clamping plate 835 and the second clamping plate 836. In this way, the fan-shaped body 830 located in the fixing hole 832 cannot fall off from the fixing hole 832.

[0127] The cutting assembly 8 includes a positioning block 821, a pressure rod 822 and a positioning rod 823. The positioning block 821 is set on the base 1. The positioning rod 823 can be a screw. The pressure rod 822 is rotatably set on the positioning block 821. In this application, the pressure rod 822 is rotatably set in the center position of the positioning block 821. The positioning rod 823 is movably set on the pressure rod 822. The first telescopic rod 833 is located on the moving path of the positioning rod 823. According to the thickness of the wire 7 and the position of the tangent tube 842, the height of the positioning rod 823 on the pressure rod 822 can be adjusted, and the positioning rod 823 can abut against the top of the first telescopic rod 833.

[0128] The positioning rod 823 is threaded, and a first threaded hole 824 is provided on the pressure rod 822. The positioning rod 823 is sleeved in the first threaded hole 824. By rotating the positioning rod 823, the height of the positioning rod 823 on the pressure rod 822 can be adjusted. The positioning rod 823 is also sleeved with a first nut 825. The first nut 825 is located at the upper end of the first threaded hole 824. The lower end surface of the first nut 825 is tightly pressed against the pressure rod 822 to prevent damage to the threads on the positioning rod 823 and the threads in the first threaded hole 824. After the height of the positioning rod 823 is determined, the first nut 825 is tightened. The first nut 825 is abutted against the fixing seat 831, and the first nut 825 increases the force-bearing area.

[0129] The third cam 57 is set on the rotating shaft 50, and the end of the pressure rod 22 is overlapped on the cam 26. The third cam 57 and the positioning rod 823 are respectively located at both ends of the pressure rod 822. The rotation of the rotating shaft 50 drives the third cam 57 to rotate. When the pressure rod 822 is lifted at the highest point of the third cam 57, the positioning rod 823 drops to the lowest position. When the end of the pressure rod 822 is overlapped on the lowest point of the third cam 57, the positioning rod 823 rises to the highest position.

[0130] A passive wheel 828 is also provided on the rotating shaft 50, and the base 1 is also provided with a motor 85 and an intermediate shaft 86. The intermediate shaft 86 is rotatably provided on the base 1. In this application, the driving end of the motor 85 is connected to the intermediate shaft 86 through a belt, and the intermediate shaft 86 is connected to the passive wheel 828 through a belt. The motor 85 drives the intermediate shaft 86 to rotate, and the intermediate shaft 86 drives the passive wheel 828 to rotate, thereby realizing the rotation of the rotating shaft 50.

[0131] Furthermore, a first rotating wheel 861 and a second rotating wheel 862 are respectively provided at both ends of the intermediate shaft 86. The driving end of the motor 85 is connected to the first rotating wheel 861 through a belt, and the second rotating wheel 862 is connected to the driven wheel 828 through a belt.

[0132] The cutting assembly 8 also includes a slide 843 and a second elastic member 844. The slide 843 is arranged on the base 1. A slide groove 845 is provided on the slide 843. The slider 841 is slidably arranged in the slide groove 845. The second elastic member 844 is located in the slide groove 845. The second elastic member 844 is also located on the sliding path of the slider 841. The slider 841 will squeeze the second elastic member 844 when sliding. In this application, the second elastic member 844 is a spring.

[0133] When the pressure rod 822 is lifted at the highest point of the third cam 57, the first telescopic rod 833 drives the fan-shaped body 830 to rotate, and the fan-shaped body 830 drives the second telescopic rod 834 to move in a straight line. The second telescopic rod 834 drives the slider 841 to move, and the movement of the slider 841 compresses the second elastic member 844. When the end of the pressure rod 822 overlaps the lowest point of the third cam 57, the first telescopic rod 833 is reset. At this time, the second elastic member 844 drives the second telescopic rod 834 to reset, and the second telescopic rod 834 drives the fan-shaped body 830 to reset.

[0134] The second screw 847 is tightened with the second nut 848 so as to abut against the slider 841.
