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 wire coil spring shape, which is similar to a circular coil shape. Its processing technology is as follows: a straight metal wire is used, one end of the metal wire is first bent into a circle, and then the other end of the metal wire is also bent into a circle along the same bending direction to form 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, the above-mentioned bending process was often completed manually, which had low processing efficiency and high labor costs. In addition, due to manual errors, the finished product structure or curvature was easily inconsistent, and there was a problem of unstable processing quality control. Since the material of the raw metal wire is often a hard material, even after bending, the two ends of the metal wire are difficult to bend smoothly, which is manifested as the two ends of the jewelry curling up. Not only is it visually unsightly, but its sharp edges can easily scratch people's skin. Production personnel have to manually apply a lot of pressure to solve the problem of edge curling, which not only consumes a lot of physical strength and takes a long time to process, but also has problems such as easy slipping and inaccurate bending direction, resulting in a low final yield rate.

[0037] The present invention discloses a filament automatic spring coiling machine, which is used for the bending and coiling of ornaments. Figure 1 The schematic diagram of the state of the workpiece before and after processing is provided to facilitate understanding of the working principle and function of the present invention.

[0038] See also 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 feeding mechanism 10 is used to feed the metal wire 1 as a workpiece, and continuously pushes the metal wire 1 to the position of the wire pressing mechanism 20 and the column winding mechanism 30. The wire pressing mechanism 20 is arranged at the rear end of the wire feeding mechanism 10, and is used to press the metal wire 1 straight, so that the metal wire 1 first maintains a straight shape, so that the subsequent bending process can maintain stability and consistency.

[0040] See also 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 also Figure 5-Figure 9 The positioning mechanism 40 includes a positioning claw 41 and a positioning claw driving mechanism 42 for driving the positioning claw 41 to move up and down. The positioning claw 41 and the telescopic column 32 are arranged opposite to each other; the end structure of the positioning claw 41 matches the structure of the metal wire 1. When the positioning claw 41 is close to the metal wire 1, the end structure of the positioning claw 41 is suitable for applying force to the metal wire 1, so that the metal wire 1 is pressed against the bottom of the telescopic column 32. The positioning claw driving mechanism 42 can be implemented by a 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 and fitting the end of the metal wire 1 on the telescopic column 32, and 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 arranged above the winding column mechanism 30, and is used to cut the straight metal wire 1. The cutting structure includes a cutting knife 61, and a cutting knife driving mechanism 62 for driving the cutting knife 61 to rise and fall; the blade of the cutting knife 61 is located between the wire pressing mechanism 20 and the processing position 31, and faces downward toward the metal wire 1. When the cutting knife 61 moves downward to cut the metal wire 1, the length of the cut metal wire 1 is the overall length of the ornament.

[0044] See also Fig.12The winding mechanism 70 includes a winding post 71 and a winding post driving mechanism 72 for driving the winding post 71 to rotate. After the winding post 71 moves to the side of the metal wire, it drives the metal wire to rotate by rotating itself, so that the metal wire is wound around the outer periphery of the telescopic post 32 in a circle, so that the metal wire is in a coiled shape. The winding post driving mechanism 72 can be implemented by a motor or a rotary cylinder.

[0045] See also Figure 5-Figure 9 The second edge pressing mechanism 80 and the cutting structure are arranged opposite to each other, and are 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 the 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 and fitting the cut end 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, and the wire pressing mechanism 20 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, and 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 together 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 the metal wire clamped on the telescopic column 32 is the workpiece to be bent.

[0048] The first edge pressing mechanism 50 works, the first pressing claw 51 extends and presses the end of the metal wire tightly and fits it on the telescopic column 32. Since the telescopic column 32 itself has an arc, the end of the metal wire 1 will also bend along the arc, so that one end (end) of the metal wire 1 achieves a curling effect. Subsequently, the winding mechanism 70 operates, the winding column 71 extends to the side of the metal wire 1 and then rotates. Since the metal wire 1 is pressed tightly against the telescopic column 32, the rotation of the winding column 71 drives the metal wire 1 to rotate and wind around the telescopic column 32, and the middle section of the metal wire 1 (that is, the part except the two ends) is bent into a round roll. At this time, the second edge pressing mechanism 80 operates, the second pressing claw 81 extends and acts on the cut end of the metal wire 1 (that is, the opposite end of the above-mentioned end), and the second pressing claw 81 presses the cut end tightly against the telescopic column 32, so that the cut end is bent along the arc of the telescopic column 32 itself, achieving the effect of curling the end. Thus, both ends of the metal wire 1 are bent to an ideal curvature. After the bending is completed, the telescopic column 32 retracts backward into the column hole. The accessories hanging on the telescopic column 32 will not retract into the hole due to their larger outer diameter. After losing the support of the telescopic column 32, they naturally fall down and fall into 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, and the bending process of the metal wire is realized in an automated manner to obtain the finished product of the filigree spring ornaments, which 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 that the two ends of the filigree spring ornaments are easy to warp and difficult to bend accurately. The two ends of the ornaments can be bent to the ideal arc efficiently and accurately, avoiding the problem of sharp edges of the ornaments and potential scratches. In addition, the bending direction and pressure are consistent, the product quality is stable, and the final yield rate is high.

[0050] See also Figure 6-Figure 9 Specifically, a first arc-shaped groove 511 is provided at the end of the first pressing claw 51, and the curvature of the first arc-shaped groove 511 matches the curvature of the telescopic column 32; thus, when the first arc-shaped groove 511 presses the end of the metal wire 1 against the telescopic column 32, the curvatures of the two are matched and matched, so that the end of the metal wire 1 fits well with the curvature, thereby achieving a stable bending effect. Similarly, a second arc-shaped groove 811 is provided at the end of the second pressing claw 81, and the curvature of the second arc-shaped groove 811 matches the curvature of the telescopic column 32; thus, when the second arc-shaped groove 811 presses the cut end of the metal wire 1 against the telescopic column 32, the curvatures of the two are matched and matched, so that the cut end of the metal wire 1 fits well with the curvature, thereby achieving a stable bending effect.

[0051] Specifically, see Figure 6 and Fig. 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 for multiple turns to form a coil spring structure.

[0052] Specifically, see Figure 5 The present invention further includes a mounting substrate 90, which is arranged vertically. The processing position 31, the positioning mechanism 40, the first edge pressing mechanism 50, the cutting mechanism 60, and the second edge pressing mechanism 80 are all arranged on the mounting substrate 90, forming a compact arrangement structure on the processing position 31. The winding mechanism 70 is arranged on the front side of the mounting substrate 90, so that the winding column 71 can approach or move away from the metal wire 1; the telescopic column 32 is arranged on the rear side of the mounting substrate 90, so that the telescopic column 32 can be extended forward and backward so that the metal wire 1 can be wound thereon or fall off.

[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 so as 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 Fig.12 The winding mechanism 70 further includes a rotating drum 73 and a slide cylinder 74. The winding column 71 is arranged at an eccentric position at the end of the rotating drum 73; the winding column driving mechanism 72 is connected to the rotating drum 73, driving the rotating drum 73 to rotate, thereby making the winding column 71 rotate eccentrically. The slide cylinder 74 is used to drive the rotating drum 73 to move forward and backward or left and right, so that the rotating drum 73 makes a linear reciprocating motion close to or away from the metal wire.

[0055] Before the winding action is performed, the slide cylinder 74 drives the rotating drum 73 to move to the side of the processing position 31, so that the winding column 71 is located at the side of the metal wire 1. Then the winding column 71 driving cylinder is started, so that the winding column 71 rotates eccentrically in the corresponding direction, thereby bending the metal wire and winding it on the telescopic column 32. After the winding action is completed, the slide cylinder 74 drives the rotating drum 73 to withdraw in the opposite direction.

[0056] Specifically, see Figure 5The wire feeding mechanism 10 includes: a wire harness drum 11, a wire adjusting device 12 and an anti-twisting device 13. The wire harness drum 11 has a winding portion for winding the metal wire 1, which is used to store the metal wire 1; the wire harness drum 11 drives the metal wire 1 to unwind by rotating, so as to play a feeding role.

[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 up and down; 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 the transportation process.

[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 also has a wire passage 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 posture during the conveying process to ensure 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 pressing mechanism 50 and the second edge pressing mechanism 80, and is used to control each mechanism to work in coordination according to a certain process. The specific electrical control method used is a known technology in the field, which is not within the scope of improvement of the present invention and will not be described in detail.

Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
