Description

Technical Field

[0001] This invention relates to the field of precious metal processing technology, and in particular to a laser welding rope chain machine. Background Technology

[0002] In the manufacture of jewelry, especially necklaces, a high level of automation is required. Ordinary necklaces are made of several small metal (such as gold or silver) rings interlocked together. This process is relatively simple, and most existing automatic chain welding machines can complete it automatically. However, for some necklaces with special structures, such as braided chains, the chain is not simply formed by interlocking rings. It is formed by two half-rings being attached together, and the two ends of the half-rings are staggered when they are attached. They are then fixed by laser welding, and this process is repeated to form a braided chain. However, in the current technology, there is no fully automated laser welding machine for rope chains.

[0035] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium.

The directional terms mentioned in the embodiments of the present invention, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention.

[0037] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0039] References to "one embodiment" or "some embodiments" as used in this specification mean that one or more embodiments of the invention include a particular feature, structure, or characteristic described in connection with that embodiment.

The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless otherwise specifically emphasized. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0040] like Figures 1-13 As shown, the present invention provides a laser welding rope chain machine, characterized in that it includes: a wire frame 10, a feeding assembly 20, a semi-forming shearing assembly 30, an extrusion conveying assembly 40, an upper clamping rotating assembly 50, a side clamping rotating assembly 60, a lower clamping rotating assembly 70, and a laser welder; the upper clamping rotating assembly 50 and the lower clamping rotating assembly 70 are arranged vertically opposite each other, the upper clamping rotating assembly 50 can be raised and lowered relative to the lower clamping rotating assembly 70, the side clamping rotating assembly 60 is located behind the lower clamping rotating assembly 70 and corresponds to the lower clamping rotating assembly 70, the feeding assembly 20 is located in front of the lower clamping rotating assembly 70, the wire frame 10 is located in front of the feeding assembly 20, the semi-forming shearing assembly 30 is located at the discharge end of the feeding assembly 20 and can be raised and lowered, and the extrusion conveying assembly 40 is located in front of the feeding assembly 20. The device features a side sliding connection. The wire rack 10 holds the wire, the feeding assembly 20 conveys the wire, the semi-forming shearing assembly 30 shapes the wire into a preliminary shape and cuts it, the extrusion conveying assembly 40 extrudes the pre-shaped wire and conveys it above the lower clamping rotating assembly 70, the upper clamping rotating assembly 50 clamps the wire conveyed by the extrusion conveying assembly 40 during a predetermined stroke and rotates it to an angle compatible with the operation of the side clamping rotating assembly 60, the side clamping rotating assembly 60 clamps the wire clamped by the upper clamping rotating assembly 50 during a predetermined stroke and rotates it, the lower clamping rotating assembly 70 clamps the wire clamped by the side clamping rotating assembly 60 and rotates it by a predetermined angle, and the laser welder welds the wire clamped by the lower clamping rotating assembly 70 during a predetermined stroke.

[0041] Specifically, the wire frame 10 is mainly used to place and level the raw materials, allowing them to smoothly enter the feeding assembly 20. The feeding assembly 20 is used to convey the raw materials according to a set program. The semi-finished shearing assembly shears the continuous raw materials conveyed by the feeding assembly 20, and then performs preliminary shaping treatment on the sheared raw materials with the extrusion conveying assembly 40 to form a first material, giving it a preliminary shape. The extrusion conveying assembly 40 then extrudes the pre-shaped first material to a predetermined thickness. Subsequently, the extrusion conveying assembly 40 conveys the first material to the area above the lower clamping rotating assembly 70. Then, the upper clamping rotating assembly 50 clamps the first material conveyed by the extrusion conveying assembly 40. The extrusion conveying assembly 40 resets, and the upper clamping rotating assembly 50 rotates, causing the clamped first material to rotate by a predetermined angle, changing it from a frontal view to a left or right view. Then, it descends to a height corresponding to the side clamping rotating assembly 60. The side clamping rotating assembly 60 clamps the first material and rotates it 180° to change it from an inverted position to an upright position. At this time, the lower clamping rotating assembly 70 clamps the first material, and the side clamping rotating assembly 60 releases the first material and resets. When the next material comes, the feeding assembly 20 and the extrusion conveying assembly 40 repeat the process to form the second material. The upper clamping rotating assembly 50 clamps the second material and rotates it at a predetermined angle before descending to meet the two ends of the first material on the upper clamping rotating assembly 50. During this process, the side clamping rotating assembly 60 does not work. The upper clamping rotating assembly 50 makes the first material and the second material form a ring with a certain degree of twist. At this time, the laser welder first welds and fixes one end of the first material and the second material. Then the lower clamping 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 into a closed-loop material. This process is repeated. The next first material will be hooked into the material of the previous closed loop by the side clamping rotating assembly 60. The chain formed will hang down from the middle of the lower clamping rotating assembly 70, which can prevent the lower clamping rotating assembly 70 from pulling the chain when rotating.

[0042] Furthermore, one end of the wire frame 10 is fixedly connected to the workbench, and the end of the wire frame 10 away from the workbench is provided with a wire spool rod 11 for placing the wire spool. Below the wire spool rod 11 is a pressure angle device 12 for adjusting the feed angle of the wire. On one side of the pressure angle device 12 are a first leveler 13 and a second leveler 14. 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. The raw material is drawn out from the wire reel. Since the height of the wire reel does not correspond to the height of the feeding assembly 20, a corner clamp 12 is provided to ensure smooth feeding of the wire. The corner clamp 12 brings the drawn wire to the same height as the first leveler 13 and the second leveler 14. The first leveler 13 and the second leveler 14 then straighten the wire and prevent the wire from jumping during the conveying process. The adjustment directions of the first leveler 13 and the second leveler 14 are different. One of them adjusts from the top and bottom, and the other adjusts from the front and back. At the same time, the first leveler 13, the second leveler 14 and the corner clamp 12 can also adjust the tension.

[0044] Furthermore, the feeding assembly 20 includes: a feeding mounting base 21, a feeding feed block 22, and a discharging block 23. The feeding mounting base 21 is fixedly mounted on the workbench. The feeding feed block 22 is slidably mounted on one end of the feeding mounting base 21 adjacent to the wire frame 10. The discharging block 23 is located in front of the feeding feed block 22. Both the feeding feed block 22 and the discharging block 23 have a material channel for the wire to pass through. The extrusion conveying assembly 40 is slidably connected to the feeding mounting base 21.

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

[0046] Furthermore, in this embodiment, the semi-forming shearing assembly 30 includes: a lower forming mold 33 and an upper forming mold 31; the lower forming mold 33 and the upper forming mold 31 are respectively slidably disposed in front of the feeding assembly 20, the upper forming mold 31 and the lower forming mold 33 are vertically opposite each other, the ends of the upper forming mold 31 and the lower forming mold 33 are respectively provided with a mold cavity 32 that forms a circle after mutual cooperation, and the lower forming mold 33 cooperates with the discharge end of the feeding assembly 20 to shear the wire after rising;

[0047] Specifically, the lower forming mold 33 and the upper forming mold 31 are vertically corresponding and can be raised and lowered respectively. When the material is sent out from the discharge block 23, the lower forming mold 33 rises and the upper forming mold 31 falls. The ends of the two molds abut each other. In order to avoid squeezing the material in this direction, mold cavities 32 are respectively opened at the ends of the lower forming mold 33 and the upper forming mold 31. Both mold cavities 32 are semi-circular and are used to cooperate with the extrusion conveying assembly 40 to form a semi-circular arc under the restriction of the mold cavity 32. The lower forming mold 33 also undertakes the function of shearing. The side of the lower forming mold 33 adjacent to the discharge block 23 will form a shearing force with the discharge nozzle of the discharge block 23 when it rises, so as to cut the material.

[0048] Furthermore, in this embodiment, the extrusion conveying assembly 40 includes: 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 disposed on the die head 42, the die core 43 is slidably disposed inside 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] Furthermore, a pressure block 45 is adapted to the extrusion die 44, and the extrusion die 44 is opposite to the pressure block 45 during a predetermined stroke;

[0050] Specifically, the extrusion slider 41 is slidably disposed on the side of the feeding mounting base 21. The extrusion slider 41 can slide along the material conveying direction. That is, in this embodiment, the material is conveyed from left to right, so the extrusion slider 41 can slide left and right along the feeding assembly 20. The die head 42 is slidably connected to the extrusion slider 41. The die head 42 can slide back and forth relative to the extrusion slider 41. The extrusion die sleeve 44 is fixedly disposed at the end of the die head 42. When the die head 42 slides back and forth, it drives the extrusion die sleeve 44 to slide back and forth synchronously. The die core 43 is slidably disposed inside the extrusion die sleeve 44. The die core 43 can slide freely back and forth inside the extrusion die sleeve 44. When the material is conveyed out of the discharge block 23 for 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. At the same time, the die core 43 protrudes from the extrusion die sleeve 44 and is located below the material. Then the upper forming die 31 descends, and the lower forming die 3... 3. The material is raised and sheared. At this time, the mold core 43 is located in the middle of the mold cavity 32, and the diameter of the mold core 43 is smaller than the diameter of the mold cavity 32, so that the material is placed on the mold core 43. Due to the extrusion of the upper forming mold 31 and the lower forming mold 33, the material is formed into a semi-circular arc. Then, the extrusion sleeve 44 moves back and forth under the drive of the mold head 42. At this time, the extrusion sleeve 44 pushes the material and cooperates with the pressure block 45 to extrude in the back and forth direction, so that the material changes from the original columnar arc shape to a flat arc shape. During the extrusion process, the mold core 43 does not move, so that it can hold the material and prevent the material from extending towards the center during extrusion. After the extrusion is completed, the mold head 42 returns to its original position, the upper forming mold 31 and the lower forming mold 33 return to their original positions, the mold core 43 extends, the extrusion slider 41 slides, and the first material formed is transported to the lower part of the upper clamping rotating assembly 50 through the mold core 43. The extension of the mold core 43 is to make the material within the clamping range of the upper clamping rotating assembly 50.

[0051] Furthermore, in this embodiment, the upper clamping rotating assembly 50 includes: an upper clamping mold sleeve 51, an upper clamping fixture 52, and an upper clamping ejector pin 53; the upper clamping fixture 52 is slidably disposed inside one end of the upper clamping mold, and the end of the upper clamping fixture 52 extends out of the upper clamping mold sleeve 51; the tail end of the upper clamping fixture 52 is provided with an upper clamping spring for keeping the upper clamping fixture 52 in a clamping state at all times; the upper clamping ejector pin 53 is slidably disposed inside the upper clamping mold sleeve 51; the upper clamping ejector pin 53 controls the clamping state of the upper clamping fixture 52 by sliding; an upper clamping rotating sleeve 54 is also rotatably disposed inside the upper clamping mold sleeve 51; an upper clamping rack 55 is also slidably disposed on the outside of the upper clamping mold sleeve 51; the upper clamping rack 55 is kinetically 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, with an upper clamping spring at its tail end. The upper clamping spring pulls the tail ends of the upper clamp 52 closer together, separating their front ends and maintaining this state. The upper clamp 52 is then controlled by the sliding of the upper clamping pin 53. When the upper clamping pin 53 slides towards the upper clamp 52, it inserts into the tail end of the upper clamp 52. The intervention of the upper clamping pin 53 compresses the tail ends of the upper clamp 52, causing them to move away from each other and towards each other, thus forming a clamping shape. The upper clamping rotating sleeve 54 drives the upper clamp 52 to rotate. The rotation of the upper clamping rotating sleeve 54 is achieved by the movement of the upper clamping rack 55. The outer side of the rotating sleeve 54 is provided with a toothed groove that meshes with the upper clamping rack 55, so that the upper clamping rotating sleeve 54 rotates under the drive of the upper clamping rack 55. The upper clamping rotating sleeve 54 then drives the upper clamping fixture 52 to rotate. The upper clamping mold sleeve 51 can be raised and lowered, and the upper clamping rotating sleeve 54 can also be raised and lowered within the upper clamping mold 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 bring the inverted second material into contact with the upright end of the first material, 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 at a predetermined angle and descends to match the height of the side clamping rotating assembly 60. The side clamping rotating assembly 60 clamps the first material and rotates it.

[0053] Furthermore, in this embodiment, the side clamp rotation assembly 60 includes: a side clamp mold sleeve 61, a side clamp clamp 62, and a side clamp ejector pin 63; the side clamp clamp 62 is fixedly disposed outside one end of the side clamp mold sleeve 61, the side clamp ejector pin 63 is slidably disposed inside the side clamp mold sleeve 61, and the side clamp ejector pin 63 controls the clamping state of the side clamp clamp 62 by sliding; a side clamp rotating sleeve 64 is also rotatably disposed inside the side clamp mold sleeve 61; a side clamp rack 65 is also installed on the side of the side clamp mold sleeve 61; the side clamp rack 65 is pulsatorically connected to the side clamp mold sleeve 61; and the side clamp clamp 62 is fixedly connected to the side clamp rotating sleeve 64.

[0054] Specifically, the side clamp 62 and the upper clamp 52 have different structures. The upper clamp 52 has two moving clamping arms, while the side clamp 62 has only one moving clamping arm. The other arm is located at the rotation center of the side clamping sleeve 64 and will only rotate without interacting with the other clamping arm to form a clamp. That is, the side clamp 62 has only one moving clamping arm to form a clamping state. In this way, the stationary clamping arm can be located at the center of the first material, clamping the first material and rotating it so that one end of the first material passes through 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] Furthermore, in this embodiment, the lower clamping rotating assembly 70 includes: a lower clamping mold sleeve 71, a lower clamping fixture 72, and a lower clamping ejector pin 73; the lower clamping fixture 72 is disposed at one end of the lower clamping mold sleeve 71, the lower clamping ejector pin 73 is slidably disposed within the lower clamping mold sleeve 71, and the lower clamping ejector pin 73 controls the clamping state of the lower clamping fixture 72 by sliding; a lower clamping rotating sleeve 74 is also rotatably disposed within the lower clamping mold sleeve 71, the lower clamping rotating sleeve 74 is fixedly connected to the lower clamping fixture 72, and a lower clamping rack 75 is also slidably connected within the lower clamping mold sleeve 71, the lower clamping rack 75 is drively connected to the lower clamping rotating sleeve 74;

[0056] Specifically, the lower clamp 72 also performs the clamping action through the sliding of the lower clamp pin 73. When the side clamp 62 rotates the first material, the lower clamp 72 also rotates, aligning the two clamping arms radially with the first material and clamping it. Subsequently, after the second material is formed, the upper clamp 52 clamps the second material and rotates to the direction corresponding to the lower clamp 72 before descending. The first and second materials have a certain angle difference, so that the two ends of the first and second materials are staggered and fitted together, i.e., the first and second materials are intersecting rather than parallel. Then, the laser welder welds the first end. After welding, the upper clamp 52 and the lower clamp 72 rotate synchronously in the same direction, so that the second end is within the working range of the laser welder. Welding is performed within the enclosure to form a closed-loop material. The synchronous rotation of the upper clamp 52 and the lower clamp 72 in the same direction is to prevent the second end from not fitting properly. When the next first material is delivered, the side clamp 62 clamps the first material and rotates it so that it hooks into the material of the previous closed loop. Then the lower clamp 72 releases the material of the closed loop, the upper clamp 52 descends and clamps the first material that is not closed, the side clamp 62 releases and resets, the upper clamp 52 descends again and is sent into the clamping range of the lower clamp 72, clamping the lower clamp 72. After that, the upper clamp 52 releases and clamps the second material and delivers it to cooperate with the first material that is not closed to form a closed-loop material. At this point, the closed loop of the two materials is completed and they are fastened together.

[0057] The movement of each component is driven by the crankshaft, such as the lifting and rotation of the upper clamping rotating component 50, the sliding of the feeding component 20, the rotation of the side clamping component, and the rotation of the lower clamping component. For details, please refer to Chinese Invention Patent No. CN202220988303.9, which is prior art and will not be elaborated here. Furthermore, the upper clamping pin 53, the lower clamping pin 73, and the side clamping pin 63 are all connected to return springs. When a predetermined action is performed, the return springs are stretched, and after the action is completed, they automatically reset themselves.

[0058] In summary, this application achieves the weaving of the twisted chain through the cooperation of various components, and the entire process is automated, reducing manual operation and significantly improving the forming rate and work efficiency.

[0059] The present invention is not limited to the description in the specification and embodiments, and other advantages and modifications can be readily realized by those skilled in the art. Therefore, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, the present invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
