Description

Technical Field

[0001] The invention relates to the field of jewelry processing, and in particular to an automatic filigree spring winding machine. Background Art

[0002] In the field of jewelry processing, one of the jewelry styles (see Figure 1 ) is a filigree coil spring shape, which is similar to a circular coil. Its processing technology is as follows: use a straight wire, first bend one end of the wire into a circle, and then bend the other end of the wire into a circle along the same bending direction, forming a coiled form similar to an outer circle wrapped around an inner circle. The specific structure of the finished product is shown in Figure 1 .

[0003] In the past, this bending process was often completed manually, resulting in low efficiency and high labor costs. Furthermore, manual errors often led to inconsistent finished product structure and curvature, resulting in unstable quality control. Because the raw wire is often made of a hard material, even after bending, the ends of the wire struggled to achieve a smooth bend, resulting in the ends of the jewelry warping. This was visually unsightly and its sharp edges could easily scratch skin. Production staff had to manually apply significant pressure to correct the warping, which was physically demanding and time-consuming. It also created issues such as slippage and inaccurate bending directions, ultimately leading to a low yield rate. Summary of the Invention

[0016] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0017] During operation: After receiving the wire feed, the wire pressing mechanism presses the raw metal wire straight, keeping it straight during transportation. After the wire is delivered to the processing position, the telescopic column in the column hole extends outward, and the positioning claw of the positioning mechanism extends upward to press the wire against the bottom of the telescopic column. In other words, the positioning claw and the telescopic column work together to clamp and position the wire. The cutting mechanism's cutting knife then moves downward to cut the wire. The section of wire clamped on the telescopic column is the workpiece to be bent. After bending is completed, the telescopic column retracts back into the column hole. The accessories hanging on the telescopic column, due to their larger outer diameter, cannot retract into the hole. Without the support of the telescopic column, they naturally fall down and land in the receiving tray below.

[0018] The first edge-pressing mechanism operates, with the first pressing claw extending and pressing the end of the metal wire tightly against the telescopic column. Since the outer periphery of the telescopic column has a curvature, the end of the metal wire is also bent along this curvature, achieving the effect of curling one end. The winding mechanism then operates, with the winding post extending to the side of the metal wire and rotating, winding the straight metal wire around the outer periphery of the telescopic column to bend the middle section of the metal wire (i.e., the middle portion excluding the two ends) into a circular coil. The second edge-pressing mechanism then operates, with the second pressing claw extending and acting on the cut end of the metal wire (the end opposite the aforementioned end of the metal wire), pressing the cut end tightly against the outer periphery of the telescopic column, thereby bending the cut end along the curvature of the telescopic column, achieving the effect of curling the end, thereby allowing both ends of the metal wire to be bent to a desired curvature.

[0019] The present invention, through the coordinated cooperation of the above-mentioned mechanisms, realizes the bending process of the metal wire in an automated manner, and obtains the finished filigree spring ornaments. It has high production efficiency, can save a lot of labor costs, and the processed products have high consistency and stable processing quality.

It can efficiently and accurately bend the ends of the ornaments to the ideal arc, avoiding the problem of sharp edges and potential scratches on the ornaments. Moreover, the bending direction and pressure are consistent, the product quality is stable, and the final yield rate is high. BRIEF DESCRIPTION OF THE DRAWINGS

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0037] The present invention discloses a filigree automatic spring coiling machine for the production of bends and coils for ornaments. Figure 1 Schematic diagram of the workpiece before and after processing to facilitate understanding of the working principle and function of the present invention.

[0038] See Figure 2-Figure 5 The automatic filament spring winding machine includes: a wire feeding mechanism 10, a wire pressing mechanism 20, a column winding mechanism 30, a positioning mechanism 40, a first edge pressing mechanism 50, a cutting mechanism 60, a winding mechanism 70 and a second edge pressing mechanism 80.

[0039] The wire feed mechanism 10 is used to convey the metal wire 1 as a workpiece, continuously pushing the metal wire 1 to the positions of the wire pressing mechanism 20 and the column winding mechanism 30. The wire pressing mechanism 20 is located at the rear end of the wire feed mechanism 10 and is used to press the metal wire 1 straight, so that the metal wire 1 maintains a straight shape to ensure stability and consistency in the subsequent bending process.

[0040] See Figure 10-11The column winding mechanism 30 is arranged at the rear end of the wire pressing mechanism 20, and includes a processing position 31 and a telescopic column 32. The processing position 31 is the position where the metal wire 1 is bent and rolled. A column hole is provided on the processing position 31. The telescopic column 32 is in a freely retractable state inside the column hole. It can extend out of the column hole of the processing position 31, or retract into the column hole of the processing position 31. When the telescopic column 32 extends out of the column hole, the telescopic column 32 is located above the metal wire 1; the outer periphery of the telescopic column 32 has an arc-shaped structure. Of course, the column winding mechanism 30 also includes a telescopic column driving mechanism 33, which is used to make the telescopic column 32 perform linear reciprocating motion, thereby extending outward or retracting into the column hole; the telescopic column driving mechanism 33 can be implemented by a cylinder.

[0041] See Figure 5-Figure 9 The positioning mechanism 40 includes a positioning claw 41 and a positioning claw drive mechanism 42 for driving the positioning claw 41 upward and downward. The positioning claw 41 is arranged opposite the telescopic column 32. The end structure of the positioning claw 41 matches the structure of the metal wire 1. When the positioning claw 41 approaches and abuts against the metal wire 1, the end structure of the positioning claw 41 is suitable for applying force to the metal wire 1, thereby tightening the metal wire 1 against the bottom of the telescopic column 32. The positioning claw drive mechanism 42 can be implemented using a pneumatic cylinder.

[0042] Continue reading Figure 5-Figure 9 , the first edge pressing mechanism 50 and the wire pressing mechanism 20 are arranged opposite to each other. The first edge pressing mechanism 50 includes a first pressing claw 51 and a first pressing claw driving mechanism 52 for driving the first pressing claw 51 to perform linear motion. The end structure of the first pressing claw 51 matches the peripheral structure of the telescopic column 32. When the first pressing claw 51 approaches and fits on the end of the metal wire 1, the end structure of the first pressing claw 51 is suitable for applying a force to the end of the metal wire 1 (the end away from the wire feeding mechanism 10), thereby pressing the end of the metal wire 1 and fitting it on the telescopic column 32. The end is bent into an arc shape, and its curvature is equivalent to that of the telescopic column 32. The first pressing claw driving mechanism 52 can be implemented by a cylinder.

[0043] Continue reading Figure 5-Figure 9 The cutting mechanism 60 is positioned above the winding mechanism 30 and is used to cut the straight metal wire 1. The cutting mechanism includes a cutting blade 61 and a cutting blade drive mechanism 62 for driving the cutting blade 61 upward and downward. The blade of the cutting blade 61 is positioned between the wire pressing mechanism 20 and the processing station 31, facing downward toward the metal wire 1. When the cutting blade 61 moves downward to cut the metal wire 1, the length of the cut wire 1 is the overall length of the jewelry.

[0044] See Figure 12The winding mechanism 70 includes a winding post 71 and a winding post drive mechanism 72 for rotating the winding post 71. After the winding post 71 moves to the side of the wire, it rotates to rotate the wire, causing the wire to be wound around the outer circumference of the telescopic post 32 in a coiled shape. The winding post drive mechanism 72 can be implemented using a motor or a rotary cylinder.

[0045] See Figure 5-Figure 9 The second edge pressing mechanism 80 is arranged opposite to the cutting structure and is used to bend the end of the metal wire cut by the cutting knife 61. The second edge pressing mechanism 80 includes a second pressing claw 81 and a second pressing claw driving mechanism 82 for driving the second pressing claw 81 to move linearly. The end structure of the second pressing claw 81 matches the peripheral structure of the telescopic column 32. When the second pressing claw 81 moves to a position where it fits the cut end of the metal wire, the structure of the second pressing claw 81 is suitable for applying force to the cut end of the metal wire, thereby pressing the cut end and fitting it to the telescopic column 32. The cut end is bent into an arc shape, and its curvature is equivalent to that of the telescopic column 32. The second pressing claw driving mechanism 82 can be implemented by a cylinder.

[0046] The workflow of the present invention is as follows:

[0047] The wire feeding mechanism 10 conveys the metal wire 1 to the wire pressing mechanism 20, which presses the metal wire 1 straight to keep it straight during the conveying process. After the metal wire 1 is conveyed to the processing position 31 of the column winding mechanism 30, the telescopic column 32 in the column hole extends outward. The telescopic column 32 is now located above the metal wire 1. At this time, the positioning claw 41 of the positioning mechanism 40 extends upward to press the metal wire against the bottom of the telescopic column 32. That is, the positioning claw 41 and the telescopic column 32 jointly clamp and position the metal wire. Then, the cutting knife 61 of the cutting mechanism 60 moves downward, and the blade cuts the metal wire. The cut section of metal wire clamped on the telescopic column 32 is the workpiece to be bent.

[0048] The first pressing mechanism 50 operates, with the first pressing claw 51 extending and pressing the end of the wire tightly against the telescopic column 32. Since the telescopic column 32 has a curvature, the end of the wire 1 is also bent along this curvature, resulting in a curled end. Subsequently, the winding mechanism 70 operates, with the winding post 71 extending to the side of the wire 1 and then rotating. Since the wire 1 is pressed tightly against the telescopic column 32, the rotation of the winding post 71 causes the wire 1 to rotate and wind around the telescopic column 32, bending the middle section of the wire 1 (i.e., the portion excluding the two ends) into a circular coil. At this point, the second pressing mechanism 80 operates, with the second pressing claw 81 extending and acting on the cut end of the wire 1 (i.e., the end opposite the aforementioned end). The second pressing claw 81 presses the cut end tightly against the telescopic column 32, causing it to bend along the curvature of the telescopic column 32, resulting in a curled end. Thus, both ends of the metal wire 1 are bent to the desired curvature. After the bending is completed, the telescopic column 32 retracts back into the column hole. The jewelry hanging on the telescopic column 32, due to its larger outer diameter, cannot retract into the hole. Without the support of the telescopic column 32, it naturally falls down and lands in the receiving tray 110 below.

[0049] Through the coordinated cooperation of the above-mentioned mechanisms, the bending process of the metal wire 1 is realized. The bending process of the metal wire is realized in an automated manner, and the finished filigree spring jewelry is obtained. This has high production efficiency and can save a lot of labor costs. At the same time, the processed products have high consistency and stable processing quality. At the same time, it also solves the problem of the ends of filigree spring jewelry being prone to warping and difficult to bend accurately. The ends of the jewelry can be bent efficiently and accurately to the ideal arc, avoiding the problem of sharp edges and potential scratches on the jewelry. Moreover, the bending direction and pressure are consistent, the product quality is stable, and the final yield rate is high.

[0050] See Figure 6-Figure 9 Specifically, the end of the first pressing jaw 51 is provided with a first arcuate groove 511, the curvature of which matches that of the telescopic column 32. Thus, when the first arcuate groove 511 presses the end of the metal wire 1 against the telescopic column 32, the curvatures of the two arcs match, allowing the end of the metal wire 1 to fit well within the arc, thereby achieving a stable bending effect. Similarly, the end of the second pressing jaw 81 is provided with a second arcuate groove 811, the curvature of which matches that of the telescopic column 32. Thus, when the second arcuate groove 811 presses the cut end of the metal wire 1 against the telescopic column 32, the curvatures of the two arcs match, allowing the cut end of the metal wire 1 to fit well within the arc, thereby achieving a stable bending effect.

[0051] Specifically, see Figure 6 and Figure 9The specific structure of the telescopic column 32 includes: a push pin 321 and a forming tube 322. The forming tube 322 is in an arc-top shape and surrounds the upper part of the push pin 321. The end of the positioning claw 41 is provided with a protruding crimping portion 411, which is used to press the metal wire 1 against the bottom of the push pin 321, thereby clamping the metal wire 1 between the push pin 321 and the positioning claw 41. The push pin 321 and the crimping portion 411 are arranged opposite to each other in the vertical direction. During the winding process, the metal wire is clamped at the bottom of the push pin 321, and the rotation of the winding column 71 causes the metal wire 1 to be wound around the forming tube 322 and the push pin 321 multiple times to form a coil spring structure.

[0052] Specifically, see Figure 5 The present invention also includes a mounting base 90, which is arranged vertically. The processing station 31, positioning mechanism 40, first edge-holding mechanism 50, cutting mechanism 60, and second edge-holding mechanism 80 are all arranged on the mounting base 90, forming a compact arrangement on the processing station 31. The winding mechanism 70 is arranged on the front side of the mounting base 90, facilitating the winding post 71 to move closer to or further away from the metal wire 1. The telescopic post 32 is arranged on the rear side of the mounting base 90, facilitating its forward and backward extension to allow the metal wire 1 to be wound around or removed.

[0053] Specifically, see Figure 5 The wire pressing mechanism 20 and the first edge pressing mechanism 50 are arranged opposite to each other in the horizontal direction to transport the metal wire 1 in the horizontal direction; the cutting mechanism 60 is arranged in the vertical direction so that the cutting knife 61 can cut in the vertical direction and quickly cut the metal wire 1.

[0054] Specifically, see Figure 12 The winding mechanism 70 also includes a rotating drum 73 and a slide cylinder 74. A winding post 71 is positioned eccentrically at the end of the rotating drum 73. A winding post drive mechanism 72 is connected to the rotating drum 73, driving the rotating drum 73 to rotate, thereby causing the winding post 71 to rotate eccentrically. The slide cylinder 74 drives the rotating drum 73 forward and backward or left and right, causing it to move back and forth in a straight line, moving toward or away from the wire.

[0055] Before winding, the slide cylinder 74 drives the rotary drum 73 toward the processing station 31, positioning the winding post 71 to the side of the wire 1. The cylinder driving the winding post 71 then activates, causing it to rotate eccentrically in the corresponding direction, thereby bending the wire and wrapping it around the telescopic post 32. After the winding is complete, the slide cylinder 74 drives the rotary drum 73 in the opposite direction and withdraws.

[0056] Specifically, see Figure 5The wire feeding mechanism 10 includes a wire reel 11, a wire adjustment device 12, and an anti-twist device 13. The wire reel 11 has a winding portion for winding the metal wire 1 and storing the metal wire 1. The wire reel 11 rotates to unwind the metal wire 1, thereby feeding the wire.

[0057] The wire adjusting device 12 is arranged at the rear end direction of the wire harness reel 11 and is located at the front end direction of the wire pressing mechanism 20. The wire adjusting device 12 includes a wire adjusting fixed seat 121 and two rows of wire adjusting rollers 122 arranged vertically; a straight gap is formed between the two rows of wire adjusting rollers 122 for the metal wire 1 to pass through; the front and rear sections of the wire adjusting fixed seat 121 are respectively provided with a wire inlet and a wire outlet. In the wire adjusting device 12, the shape of the metal wire 1 is maintained in a straight line by the action of the rollers. The anti-twisting device 13 is also provided with a wire channel for the metal wire 1 to pass through, and an anti-twisting tube is provided on the side of the wire channel for preventing the metal wire 1 from twisting, so that the metal wire 1 will not twist or deflect during transportation.

[0058] Specifically, the wire pressing mechanism 20 includes a wire pressing cylinder 21 and a wire pressing fixed block 22. The wire pressing fixed block 22 is also provided with a wire channel for the metal wire 1 to pass through. The wire pressing cylinder 21 is arranged above the wire pressing fixed block 22, and the piston rod of the wire pressing cylinder 21 faces the wire pressing fixed block 22.

[0059] Through the combined action of the wire adjusting device 12, the anti-twisting device 13 and the wire pressing mechanism 20, the metal wire 1 always maintains a stable and consistent conveying direction and position during the conveying process, thereby ensuring the stability of the processing.

[0060] Specifically, the present invention further includes a control module 100. The control module 100 is electrically connected to the wire feeding mechanism 10, the wire pressing mechanism 20, the column winding mechanism 30, the positioning mechanism 40, the cutting mechanism 60, the first edge holding mechanism 50, and the second edge holding mechanism 80, and is used to control the coordinated operation of each mechanism according to a specific process. The specific electrical control method employed is well known in the art and is not within the scope of improvement of the present invention, and will not be further described.

[0061] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
