[0040] like Figure 1-Figure 13 As shown, the utility model provides a laser welding rope chain machine, characterized in that it includes: a wire rack 10, a feeding assembly 20, a semi-molding shearing assembly 30, an extrusion conveying assembly 40, an upper clamp rotating assembly 50, a side clamp rotating assembly 60, a lower clamp rotating assembly 70, and a laser welder; the upper clamp rotating assembly 50 and the lower clamp rotating assembly 70 are arranged opposite to each other up and down, and the upper clamp rotating assembly 50 can be lifted and lowered relative to the lower clamp rotating assembly 70, the side clamp rotating assembly 60 is located at the rear side of the lower clamp rotating assembly 70 and corresponds to the lower clamp rotating assembly 70, the feeding assembly 20 is located at the front side of the lower clamp rotating assembly 70, the wire rack 10 is located at the front side of the feeding assembly 20, the semi-molding shearing assembly 30 is located at the discharge end of the feeding assembly 20 and can be lifted and lowered, the extrusion conveying assembly 40 and the feeding assembly 20 The side sliding connection, the wire rack 10 is used to place the wire, the feeding assembly 20 is used to convey the wire, the semi-formed shearing assembly 30 is used to shape the wire into a preliminary shape and shear it, the extrusion conveying assembly 40 is used to extrude the preliminary shaped wire and convey the wire to the top of the lower clamp rotating assembly 70, the upper clamp rotating assembly 50 is used to clamp the wire conveyed by the extrusion conveying assembly 40 at a predetermined stroke and rotate it to an angle compatible with the operation of the side clamp rotating assembly 60, the side clamp rotating assembly 60 is used to clamp the wire clamped by the upper clamp rotating assembly 50 at a predetermined stroke and rotate it, the lower clamp rotating assembly 70 is used to clamp the wire clamped by the side clamp rotating assembly 60 and rotate it at a predetermined angle, and the laser welder is used to weld the wire clamped by the lower clamp rotating assembly 70 at a predetermined stroke.

[0041] Specifically, the wire rack 10 is mainly used to place the raw materials and level the raw materials so that they can smoothly enter the feeding component 20. The feeding component 20 is used to convey the raw materials according to the set program. The semi-finished shearing component shears the continuous raw materials conveyed by the feeding component 20, and cooperates with the extrusion conveying component 40 to perform preliminary shaping processing on the sheared raw materials to form a first material so that it has a preliminary shape. The extrusion conveying component 40 then extrude the preliminarily shaped first material to make it have a predetermined thickness. Subsequently, the first material is conveyed to the top of the lower clamp rotating component 70 through the extrusion conveying component 40, and then the upper clamp rotating component 50 clamps the first material conveyed by the extrusion conveying component 40. The extrusion conveying component 40 is reset, and the upper clamp rotating component 50 rotates to drive the clamped first material to rotate a predetermined angle, so that it is converted from a front view state to a left view or a right view state, and then descends to a height corresponding to the side clamp rotating component 60. The side clamp rotating component 60 clamps the first material and rotates 180° to convert it from inverted to upright. At this time, the lower clamp rotating assembly 70 clamps the first material, and the side clamp rotating assembly 60 releases the first material and resets. When the next material comes over, the feeding assembly 20 and the extrusion conveying assembly 40 repeat to form the second material, and the upper clamp rotating assembly 50 clamps the second material and rotates a predetermined angle and then descends to fit the two ends of the first material on the upper clamp rotating assembly 50. In this process, the side clamp rotating assembly 60 does not work, and the upper clamp rotating assembly 50 makes the first material and the second material form a ring with a certain degree of distortion. At this time, the laser welder first welds and fixes one end of the first material and the second material, and then the lower clamp rotating assembly 70 rotates 180°, and the laser welder welds and fixes the second end. At this time, the first material and the second material are completely formed to form a closed-loop material, and then the process is repeated. The subsequent first material will be hooked in the material of the previous closed loop through the side clamp rotating assembly 60; the chain formed therein will hang down from the middle of the lower clamp rotating assembly 70, so as to prevent the lower clamp rotating assembly 70 from pulling the chain when rotating.

[0042] Further, one end of the wire rack 10 is fixedly connected to the workbench, and the end of the wire rack 10 away from the workbench is provided with a wire reel rod 11 for placing the wire reel, and an angle press 12 is provided below the wire reel rod 11 for adjusting the feeding angle of the wire, and a first leveler 13 and a second leveler 14 are provided on one side of the angle press 12, and the first leveler 13 and the second leveler 14 are respectively used to adjust the flatness of the wire during feeding, and the leveling directions of the first leveler 13 and the second leveler 14 intersect;

[0043] Specifically, the wire reel rod 11 is used to install the wire reel, and the raw material is led out from the wire reel. Since the height of the wire reel does not correspond to the height of the feeding assembly 20, in order to ensure the smooth feeding of the wire, a press angle device 12 is provided. The press angle device 12 makes the led wire and the first leveler 13 and the second leveler 14 at the same height, and then the first leveler 13 and the second leveler 14 are used to straighten the wire and prevent the wire from jumping during the transportation process. The adjustment directions of the first leveler 13 and the second leveler 14 are different. One of them is leveled from the up and down directions, and the other is leveled from the front and back directions. At the same time, the first leveler 13 and the second leveler 14 and the press angle device 12 can also adjust the tension.

[0044] Further, the feed assembly 20 includes: a feed mounting seat 21, a feed feed block 22, and a discharge block 23. The feed mounting seat 21 is fixedly arranged on the workbench, the feed feed block 22 is slidably arranged on one end of the feed mounting seat 21 adjacent to the wire rack 10, the discharge block 23 is arranged in front of the feed feed block 22, and the feed feed block 22 and the discharge block 23 are both provided with a material channel for the wire to pass through, and the extrusion conveying assembly 40 is slidably connected to the feed mounting seat 21;

[0045] Specifically, the feed mounting seat 21 is fixed on the workbench, and the feed block 22 is slidably connected to the feed mounting seat 21. The sliding of the feed block 22 is used to loosen the material and reset it after feeding a section of material, and then clamp the material and slide forward to realize feeding. The discharge block 23 is fixed, and both the feed block 22 and the discharge block 23 are provided with material channels for the material to pass through, and the material moves from the material channel.

[0046] Further, in this embodiment, the semi-molding shearing component 30 includes: a lower molding die 33 and an upper molding die 31; the lower molding die 33 and the upper molding die 31 are respectively slidably arranged in front of the feeding component 20, the upper molding die 31 is opposite to the lower molding die 33 up and down, and the ends of the upper molding die 31 and the lower molding die 33 are respectively provided with a circular mold cavity 32 after matching with each other, and the lower molding die 33 cooperates with the discharge end of the feeding component 20 to shear the wire after rising;

[0047] Specifically, the lower molding die 33 corresponds to the upper molding die 31 up and down, and can be raised and lowered respectively. When the material is sent out from the discharge block 23, the lower molding die 33 rises and the upper molding die 31 descends, and the ends of the two molds are against each other. In order to avoid squeezing the material in this direction, mold cavities 32 are respectively opened at the ends of the lower molding die 33 and the upper molding die 31. Both mold cavities 32 are semicircular and are used to cooperate with the extrusion and conveying component 40 to form a semicircular arc under the restriction of the mold cavity 32. The lower molding die 33 also has a shearing function. The side of the lower molding die 33 adjacent to the discharge block 23 will form a shear force between the discharge nozzle of the discharge block 23 when it rises, so that it shears the material.

[0048] Further, in the present embodiment, the extrusion conveying assembly 40 comprises: an extrusion slider 41, a die head 42, a die core 43, and an extrusion die sleeve 44; the extrusion slider 41 is slidably connected to the side of the feeding assembly 20, the die head 42 is slidably connected to the extrusion slider 41, the extrusion die head 42 can slide relative to the extrusion slider 41, the extrusion die sleeve 44 is arranged on the die head 42, the die core 43 is slidably arranged in the extrusion die sleeve 44, and the height of the extrusion die sleeve 44 is lower than the discharge port of the feeding assembly 20;

[0049] Further, a pressing block 45 adapted to the extrusion die sleeve 44, the extrusion die sleeve 44 is opposite to the pressing block 45 during a predetermined stroke;

[0050] Specifically, the extrusion slider 41 is slidably arranged on the side of the feed mounting seat 21, and the extrusion slider 41 can slide along the conveying direction of the material, that is, in this embodiment, the material is conveyed from left to right, then the extrusion slider 41 can slide left and right along the feed assembly 20, the die head 42 is slidably connected to the extrusion slider 41, and the die head 42 can slide back and forth relative to the extrusion slider 41, and the extrusion die sleeve 44 is fixedly arranged at the end of the die head 42, and when the die head 42 slides back and forth, it drives the extrusion die sleeve 44 to slide back and forth synchronously, and the die core 43 is slidably arranged in the extrusion die sleeve 44, and the die core 43 can slide back and forth freely in the extrusion die sleeve 44, when the material is conveyed out of the discharge block 23 to a predetermined length, the extrusion slider 41 moves to the left, driving the die head 42 to move, so that the extrusion die sleeve 44 corresponds to the protruding material, and at the same time the die core 43 protrudes from the extrusion die sleeve 44 and is located below the material, and then the upper molding die 31 descends, and the lower molding die 3 3 rises and shears the material. At this time, the die core 43 is located in the middle of the die cavity 32, and the diameter of the die core 43 is smaller than the diameter of the die cavity 32, so that the material is placed on the die core 43, and due to the extrusion of the upper molding die 31 and the lower molding die 33, it is semicircular. Then, the extrusion die sleeve 44 moves forward and backward under the drive of the die head 42. At this time, the extrusion die sleeve 44 pushes the material and cooperates with the pressure block 45 to extrude in the front and rear directions, so that the material changes from the original cylindrical arc to a flat arc. During the extrusion process, the die core 43 does not move, so that it can hold the material and prevent the material from extending toward the center during extrusion. After the extrusion is completed, the die head 42 returns to its original position, the upper molding die 31 and the lower molding die 33 return to their original positions, the die core 43 extends out, the extrusion slider 41 slides, and the first material formed is transported to the bottom of the upper clamp rotating assembly 50 through the die core 43. The extension of the die core 43 is to make the material within the clamping range of the upper clamp rotating assembly 50.

[0051] Furthermore, in the present embodiment, the upper clamp rotating assembly 50 comprises: an upper clamping die sleeve 51, an upper clamping fixture 52, and an upper clamping ejector pin 53; the upper clamping fixture 52 is slidably arranged in one end of the upper clamping die, and the end of the upper clamping fixture 52 passes through the upper clamping die sleeve 51, and an upper clamping spring is arranged at the tail end of the upper clamping fixture 52, which is used to keep the upper clamping fixture 52 in a clamping state at all times, and the upper clamping ejector pin 53 is slidably arranged in the upper clamping die sleeve 51, and the upper clamping ejector pin 53 controls the clamping state of the upper clamping fixture 52 by sliding, and an upper clamping rotating sleeve 54 is also rotatably arranged in the upper clamping die sleeve 51, and an upper clamping rack 55 is also slidably arranged on the outer side of the upper clamping die sleeve 51 of the upper clamping fixture 52, and the upper clamping rack 55 is transmission-connected to the upper clamping rotating sleeve 54, and the upper clamping rotating sleeve 54 slides with the upper clamping fixture 52;

[0052] Specifically, the upper clamp 52 is scissor-shaped, and an upper clamp spring is provided at the tail end of the upper clamp 52. The upper clamp spring is used to move the tail end of the upper clamp 52 closer to the opposite direction, so that their front ends are separated from each other, so that they are always in this state, and then the upper clamp 52 is clamped by the sliding control of the upper clamp ejector pin 53. When the upper clamp ejector pin 53 slides in the direction of the upper clamp 52, it will be inserted into the tail end of the upper clamp 52. The intervention of the upper clamp ejector pin 53 squeezes the tail end of the upper clamp 52 to move in the direction away from each other, so that the front end moves in the direction close to each other, forming a clamping shape. The upper clamp rotating sleeve 54 is used to drive the upper clamp 52 to rotate. The rotation of the upper clamp rotating sleeve 54 is realized by the movement of the upper clamp rack 55. The outer side of the rotating sleeve 54 is provided with a tooth groove meshing with the upper clamping rack 55, so that the upper clamping rotating sleeve 54 rotates under the drive of the upper clamping rack 55, and the upper clamping rotating sleeve 54 drives the upper clamping fixture 52 to rotate, wherein the upper clamping die sleeve 51 can be raised and lowered, wherein the upper clamping rotating sleeve 54 can also be raised and lowered in the upper clamping die sleeve 51 to drive the upper clamping fixture 52 to be raised and lowered. When the material is the second material, the upper clamping fixture 52 descends to put the inverted second material and the upright end of the first material together, so that the first material and the second material form a closed ring. When the material is the first material, the upper clamping fixture 52 rotates a predetermined angle and descends to make it consistent with the height of the side clamping rotating assembly 60, and the side clamping rotating assembly 60 clamps the first material for rotation.

[0053] Further, in the present embodiment, the side clamp rotating assembly 60 comprises: a side clamp die sleeve 61, a side clamp fixture 62, and a side clamp ejector pin 63; the side clamp fixture 62 is fixedly arranged outside one end of the side clamp die sleeve 61, the side clamp ejector pin 63 is slidably arranged in the side clamp die sleeve 61, and the side clamp ejector pin 63 controls the clamping state of the side clamp fixture 62 by sliding, and a side clamp rotating sleeve 64 is also rotatably arranged in the side clamp die sleeve 61, and a side clamp rack 65 is also installed on the side of the side clamp die sleeve 61, the side clamp rack 65 is transmission-connected to the side clamp die sleeve 61, and the side clamp fixture 62 is fixedly connected to the side clamp rotating sleeve 64;

[0054] Specifically, the side clamp 62 has a different structure from the upper clamp 52. The upper clamp 52 has two clamping arms that move, while the side clamp 62 has only one clamping arm that moves, and the other one is located at the rotation center of the side clamp rotating sleeve 64, and will only rotate but will not move with the other clamping arm to form a clamping state. That is, the side clamp 62 has only one clamping arm that moves to form a clamping state, so that the stationary clamping arm can be located at the center of the first material, clamp the first material and rotate it, so that one end of the first material can penetrate into the material of the previous closed loop; the side clamp 62 only moves when it is the first material, and does not move when it is the second material.

[0055] Further, in the present embodiment, the lower clamp rotating assembly 70 comprises: a lower clamping die sleeve 71, a lower clamping fixture 72, and a lower clamping ejector pin 73; the lower clamping fixture 72 is arranged at one end of the lower clamping die sleeve 71, the lower clamping ejector pin 73 is slidably arranged in the lower clamping die sleeve 71, and the lower clamping ejector pin 73 controls the clamping state of the lower clamping fixture 72 by sliding, and a lower clamp rotating sleeve 74 is rotatably arranged in the lower clamping die sleeve 71, and the lower clamp rotating sleeve 74 is fixedly connected to the lower clamping fixture 72, and a lower clamping rack 75 is slidably connected in the lower clamping die sleeve 71, and the lower clamping rack 75 is transmission-connected to the lower clamp rotating sleeve 74;

[0056] Specifically, the lower clamping fixture 72 also performs a clamping action by sliding the lower clamping pin 73. When the side clamping fixture 62 rotates the first material, the lower clamping fixture 72 also rotates, so that the two clamping arms correspond to the radial direction of the first material and clamp the first material. Then, after the second material is formed, the upper clamping fixture 52 clamps the second material and rotates to the direction corresponding to the lower clamping fixture 72, and then descends. The first material and the second material have a certain angle difference, so that the two ends of the first material and the two ends of the second material are staggered and fitted, that is, the first material and the second material are in a cross shape, not parallel. Then, the laser welder welds the first end. After the welding is completed, the upper clamping fixture 52 and the lower clamping fixture 72 rotate synchronously in the same direction, so that the second end is within the working range of the laser welder. The upper clamp 52 is lowered to the clamping range of the lower clamp 72 to clamp the lower clamp 72. After that, the upper clamp 52 is released and the second material is clamped and conveyed to cooperate with the unclosed first material for welding to form a closed loop of material. At this point, the closed loop of the two materials is completed and buckled together.

[0057] Among them, the movement of each component is driven by the crankshaft, such as the lifting and rotation of the upper clamp rotating component 50, the sliding of the feed component 20, the rotation of the side clamp component, the rotation of the lower clamp component, etc. For details, please refer to the Chinese utility model patent No. CN202220988303.9. This is a prior art, so it will not be repeated here. And the upper clamp ejector 53, the lower clamp ejector 73, and the side clamp ejector 63 are all connected with a reset spring, which will stretch the reset spring when performing a predetermined action. When the action is completed, it will reset itself through the reset spring.

[0058] In summary, the present application realizes the weaving of twisted chain through the mutual cooperation of various components, and the whole process is automated, which reduces manual operations, greatly improves the forming rate and work efficiency.

[0059] The present invention is not limited to what is described in the specification and implementation modes, and therefore, additional advantages and modifications can be easily realized by those familiar with the art. Therefore, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details, representative devices, and illustrative examples shown and described herein.
