Description

Technical Field

[0001] This invention relates to a spring coil forming device. Background Technology

[0002] In existing technologies, some inductors employ a spring coil structure. The two protruding ends of the spring coil need to meet certain length and shape requirements, and a flat portion needs to be formed on the circumferential sidewall of the protruding ends to facilitate the production and assembly of the inductor. This flat portion is typically formed by stamping. However, since the two protruding ends of the spring coil are located within a cylindrical region of the same diameter as the coil body, stamping the protruding ends can damage the coil body. Previous methods involved manually lifting the two ends of the spring coil relative to the coil body, then flattening and cutting the ends. This method requires multiple disassemblies and repositionings of the spring coil, resulting in low production efficiency and difficulty in ensuring product quality stability. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a spring coil forming equipment with high production efficiency and stable processing quality.

[0004] According to an embodiment of the present invention, a spring coil forming apparatus includes: a worktable having a flattening station and a shearing station; a fixture movably disposed on the worktable for placing a spring coil, the fixture having a movable member capable of driving the protruding end of the spring coil to move radially outward relative to the coil body; a pressing assembly movably and vertically disposed on the worktable, the pressing assembly having a flattening mechanism capable of driving the movable member to move and flatten the side of the protruding end of the spring coil; a shearing mechanism disposed between the pressing assembly and the worktable for cutting the protruding end of the spring coil; and a conveying device movably disposed on the worktable for conveying the fixture to the flattening station or the shearing station.

[0005] The spring coil forming apparatus according to embodiments of the present invention has at least the following beneficial effects:

[0006] The spring coil forming equipment with the above structure uses a jig device to position the spring coil. The jig device containing the spring coil is then transported by a conveying device to the flattening station and the shearing station. The pressing component drives the moving component to move, causing the protruding end of the spring coil to move radially outward relative to the coil body. At the same time, the pressing component punches a flattened part on the protruding end of the spring coil. The shearing mechanism then cuts the protruding end of the spring coil, thereby realizing the functions of automatically flattening and shearing the protruding end of the spring coil. This eliminates the need for multiple disassembly and positioning, resulting in high production efficiency and high quality stability of the formed spring coil.

[0007] In some embodiments of the present invention, the conveying device includes a conveying track disposed on the workbench, the flattening station and the shearing station are arranged along the extension direction of the conveying track, and one end of the conveying track is provided with a pushing mechanism that can push the fixture device to the other end of the conveying track.

[0008] In some embodiments of the present invention, a shaping station is provided on the workbench, and the flattening station, the shearing station and the shaping station are sequentially arranged on the material conveying track. The pushing mechanism includes a push block slidably disposed on the material conveying track and a telescopic cylinder connected to the push block. The push block can push the fixture device to the next station.

[0009] In some embodiments of the present invention, the workbench is provided with a stop baffle opposite to the end of the material conveying track away from the pushing mechanism, a receiving slide is provided on the front side of the material conveying track, a side-push cylinder is provided on the rear side of the material conveying track for pushing the fixture device toward the receiving slide, and a support plate located below the material conveying track to receive the fixture device is movably disposed on the workbench, and the support plate is connected to a drive structure that drives movement to support or detach from the fixture device.

[0010] In some embodiments of the present invention, the pressing assembly is provided with a second pressing block and a second punch corresponding to the shaping station. The second pressing block is used to press downward against the movable member, and the second punch is used to press downward against the extended end of the spring coil.

[0011] In some embodiments of the present invention, the fixture device includes a fixture body, the movable member being a pin arranged horizontally on the fixture body, the pin being used to pass through the coil body, the fixture body having a support portion for supporting the protruding end of the spring coil, and the fixture body having a height gap for the pin to move downward so that the protruding end of the spring coil protrudes upward from the coil body.

[0012] In some embodiments of the present invention, a first limiting block and a second limiting block are slidably disposed on the fixture body, which can move closer to or further away from each other. Both the first limiting block and the second limiting block are provided with an arc-shaped support plate that can extend into the inner circumferential wall of the coil body. The support portion is a positioning groove provided on the first limiting block or the second limiting block, and the positioning groove matches a portion of the outer circumferential wall of the protruding end of the spring coil.

[0013] In some embodiments of the present invention, the pin includes a first elongated insert and a second elongated insert arranged in parallel. The fixture body has a first channel and a second channel for the first elongated insert and the second elongated insert to move through respectively. The upper part of the first channel has a first positioning slot. The first elongated insert has a first insert plate portion that can enter and exit the first positioning slot. The upper part of the second channel has a second positioning slot. The second elongated insert has a second insert plate portion that can enter and exit the second positioning slot. When the first insert plate portion moves downward away from the first positioning slot and the second insert plate portion moves downward away from the second positioning slot, the first elongated insert and the second elongated insert are separated from each other and elastically abut against the inner circumferential surface of the coil body.

[0014] In some embodiments of the present invention, the first elongated insert and the second elongated insert are respectively provided with a first arc surface and a second arc surface that match the inner circumferential surface of the coil body. The lower part of the first channel is provided with a first arc slot opposite to the first arc surface, and the lower part of the second channel is provided with a second arc slot opposite to the second arc surface. The height gap is located between the first arc surface and the first arc slot and between the second arc surface and the second arc slot.

[0015] In some embodiments of the present invention, the flattening mechanism includes a first pressing block and a first punch. The first pressing block is used to press downward against the pin to cause the coil body to be displaced downward relative to the protruding end of the spring coil. The first punch is used to press against the fixture body and the protruding end of the spring coil to form a flattened portion at the protruding end of the spring coil.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] See Figures 1 to 4A spring coil forming device according to the present invention includes: a worktable 100, on which a flattening station 110 and a shearing station 120 are provided; a fixture device 200, movably disposed on the worktable 100, for placing a spring coil 10, the fixture device 200 having a movable member capable of driving the protruding end of the spring coil 10 to move radially outward relative to the coil body 11; a pressing assembly 300, movably and vertically disposed on the worktable 100, the pressing assembly 300 having a flattening mechanism 310 capable of driving the movable member to move and flatten the side of the protruding end of the spring coil 10; a shearing mechanism 320 disposed between the pressing assembly 300 and the worktable 100, for cutting the protruding end of the spring coil 10; and a conveying device 400, movably disposed on the worktable 100, for conveying the fixture device 200 to the flattening station 110 or the shearing station 120.

[0030] The spring coil forming equipment with the above structure uses a jig device 200 to position the spring coil 10. The jig device 200, which holds the spring coil 10, is conveyed by the conveying device 400 to the flattening station 110 and the shearing station 120 respectively. The pressing component 300 drives the movable component to move, causing the protruding end of the spring coil 10 to move radially outward relative to the coil body 11. At the same time, the pressing component 300 punches a flat part 12 on the protruding end of the spring coil 10. The shearing mechanism 320 cuts the protruding end of the spring coil 10, thereby realizing the functions of automatically flattening and shearing the protruding end of the spring coil 10. It does not require multiple disassembly and positioning, has high production efficiency, and the quality stability of the formed spring coil 10 is high.

[0031] See Figure 3 and Figure 4 The shearing mechanism 320 includes a lower cutter on the worktable and an upper cutter on the pressing assembly 300 opposite to the lower cutter. When the pressing assembly 300 moves downward close to the worktable, the upper cutter and the lower cutter cooperate to cut off the excess part of the protruding end of the spring coil 10.

[0032] See Figure 3In some embodiments of the present invention, the conveying device 400 includes a conveying track 410 disposed on the workbench 100, a flattening station 110 and a shearing station 120 arranged along the extension direction of the conveying track 410, and a pushing mechanism 420 provided at one end of the conveying track 410 for pushing the jig device 200 to the other end of the conveying track 410. It should be noted that when the pressing component 300 presses downward, the spring coil 10 located at the flattening station 110 completes the flattening function, and the spring coil 10 located at the shearing station 120 completes the cutting function, so that multiple steps can be achieved in one pressing action, resulting in high production efficiency. Among them, multiple jig devices 200 with spring coils 10 are arranged sequentially along the conveying track 410. When the pushing mechanism 420 pushes the jig device 200 to move, the jig device 200 at each station moves to the next station, thereby efficiently conveying multiple jig devices 200. Of course, in other embodiments, the conveying device 400 can also be replaced by a robotic arm.

[0033] See Figure 3 In some embodiments of the present invention, in order to consolidate the shape of the spring coil 10 after flattening and shearing, a shaping station 130 is provided on the worktable 100. The flattening station 110, the shearing station 120 and the shaping station 130 are arranged sequentially on the material conveying track 410. The pushing mechanism 420 includes a push block 421 slidably disposed on the material conveying track 410 and a telescopic cylinder 422 connected to the push block 421. The push block 421 can push the fixture device 200 to the next station. It should be noted that the flattening station 110, shearing station 120, and shaping station 130 each correspond to a fixture device 200 containing a spring coil 10. During one operation of the pushing mechanism 420, the telescopic cylinder 422 drives the push block 421 to transport the fixture device 200 at the flattening station 110 to the shearing station 120, to the shaping station 130, and to discharge the fixture device 200 at the shaping station 130. During one pressing operation of the pressing component 300, the corresponding operation steps at different stations are simultaneously realized, thereby achieving continuous forming of the spring coil 10 and greatly improving production efficiency. It should be noted that, depending on the usage requirements, the flattening station 110 and the shaping station 130 can be set to one or more.

[0034] See Figure 3In some embodiments of the present invention, the workbench 100 is provided with a stop baffle 140 opposite to the end of the conveying track 410 away from the pushing mechanism 420. The front side of the conveying track 410 is provided with a receiving slide 500, and the rear side of the conveying track 410 is provided with a side-push cylinder 510 for pushing the jig device 200 toward the receiving slide 500. A support plate 520 located below the conveying track 410 to receive the jig device 200 is movably arranged on the workbench 100. The support plate 520 is connected to a drive structure 530 for driving movement to support or detach from the jig device 200. Understandably, when the pushing mechanism 420 discharges the fixture device 200 at the shaping station 130, the fixture device 200 moves to the contact stop baffle 140, and then the side push cylinder 510 pushes the fixture device 200 towards the receiving slide 500. The lower end of the receiving slide 500 connects to the storage container, thereby collecting the spring coil 10 after the flattening, shearing, and shaping processes have been completed. Subsequently, the spring coil 10 can be removed from the fixture device 200. Since the other end of the fixture device 200 that contacts the stop baffle 140 is squeezed by another fixture device 200, in order to avoid the side push cylinder 510 being unable to completely push out the fixture device 200, the drive structure 530 drives the support plate 520 away from below the fixture device 200. Under the assistance of its own gravity, the fixture device 200 can roll onto the receiving slide 500.

[0035] See Figure 5 and Figure 6 In some embodiments of the present invention, the jig device 200 includes a jig body 210, and the movable member is a pin 220 arranged horizontally on the jig body 210. The pin 220 is used to pass through the coil body 11. The jig body 210 is provided with a support portion 230 for supporting the protruding end of the spring coil 10. The jig body 210 has a height gap for the pin 220 to move downward so that the protruding end of the spring coil 10 protrudes upward from the coil body 11. The above-mentioned fixture device 200 uses a pin 220 to pass through the coil body 11 and a support 230 to place the protruding end of the spring coil 10, thereby positioning the spring coil 10 on the fixture body 210. By applying downward force to the pin 220, the pin 220 is displaced downward relative to the fixture body 210, and the connection between the coil body 11 and the protruding end of the spring coil 10 is deformed, so that the protruding end of the spring coil 10 protrudes upward from the coil body 11, that is, the protruding end of the spring coil 10 is radially displaced outward relative to the coil body 11. At the same time, the pressing component 300 forms a flat portion 12 on the protruding end of the spring coil 10. The spring coil 10 produced using this fixture device 200 has high dimensional accuracy and quality stability, and also has high production efficiency.

[0036] See Figure 4 , Figure 5 and Figure 7The flattening mechanism 310 includes a first pressing block 311 and a first punch 312. The first pressing block 311 abuts against the pin 220 downwards, and the first punch 312 abuts against the jig body 210 and the protruding end of the spring coil 10. The pin 220 acts on the coil body 11 to deform the connection between the coil body 11 and the protruding end of the spring coil 10, so that the protruding end of the spring coil 10 protrudes upwards from the coil body 11, that is, the protruding end of the spring coil 10 is radially displaced outwards relative to the coil body 11. The first punch 312 punches the protruding end of the spring coil 10 to form a flat part 12. The flattening mechanism 310 has a simple structure and simple working method, and has a good forming effect on the spring coil 10.

[0037] See Figure 3 and Figure 4 In some embodiments of the present invention, the pressing assembly 300 is provided with a second pressing block 330 and a second punch 340 corresponding to the shaping station 130. The second pressing block 330 is used to abut downward against the pin 220, and the second punch 340 is used to abut downward against the protruding end of the spring coil 10. It should be noted that the second punch 340 is consistent in shape and size with the first punch 312, and the second pressing block 330 is consistent in shape and size with the first pressing block 311. The second pressing block 330 and the second punch 340 cooperate to shape the spring coil 10, maintain the levelness of the flat portion 12, and consolidate the shape of the spring coil 10 after flattening and shearing.

[0038] See Figure 5 and Figure 6 In some embodiments of the present invention, in order to prevent the spring coil 10 from moving along the length of the coil body 11 and to avoid the first punch 312 from misaligning with the protruding end of the spring coil 10 and damaging the coil body 11, a first limiting block 240 and a second limiting block 250 that can move closer to or further away from each other are slidably provided on the fixture body 210. The first limiting block 240 and the second limiting block 250 are both provided with an arc-shaped support plate 260 that can extend into the inner circumferential wall of the coil body 11. The support part 230 is a positioning groove provided on the first limiting block 240 or the second limiting block 250. The positioning groove matches the outer circumferential wall of the protruding end of the spring coil 10.

[0039] In some embodiments of the present invention, the upper part of the positioning groove and the side facing the coil body 11 are both provided with openings, and the sidewalls of the two positioning grooves can abut against the protruding ends of the adjacent spring coil 10. It can be understood that when placing the spring coil 10, the coil body 11 is first inserted into the pin 220, and then the first limiting block 240 and the second limiting block 250 are pushed closer to each other so that the two protruding ends of the spring coil 10 respectively enter the corresponding positioning grooves. At the same time, the arc-shaped support plate 260 extends into the coil body 11 and abuts against the inner circumferential wall of the coil body 11, thereby achieving relative fixation between the spring coil 10 and the fixture body 210, and thus ensuring that the shape and size of the spring coil 10 after stamping meet the requirements.

[0040] See Figure 6 and Figure 7 In some embodiments of the present invention, the first limiting block 240 and the second limiting block 250 are provided with a through-hole channel that runs horizontally through them. The pin 220 is movably inserted through the through-hole channel. The height gap is located within the through-hole channel to allow the pin 220 to move vertically relative to the through-hole channel. The pin 220 moves downward within the height gap and abuts against the lower part of the inner circumferential wall of the coil body 11, so that a height difference is formed between the coil body 11 and the protruding end of the spring coil 10. It should be noted that, see Figure 1 In the initial state, the protruding end of the spring coil 10 is level with the coil body 11, see [reference]. Figure 2 and Figure 4 When the pin 220 is moved downward under force, the coil body 11 is displaced downward relative to the fixture body 210, and the protruding end of the spring coil 10 protrudes upward from the coil body 11. At this time, the first punch 312 collides with the protruding end of the spring coil 10 to form a flat part 12, which will not cause damage to the coil body 11.

[0041] See Figure 6 and Figure 7In some embodiments of the present invention, the pin 220 includes a first elongated insert 221 and a second elongated insert 222 arranged in parallel. A partition 201 is provided in the perforation channel, which divides the perforation channel into a first channel 211 and a second channel 212 for the first elongated insert 221 and the second elongated insert 222 to move through. A first positioning slot 213 is provided at the upper part of the first channel 211. The first elongated insert 221 is provided with a first insert plate portion 223 that can enter and exit the first positioning slot 213. A second positioning slot 214 is provided at the upper part of the second channel 212. The second elongated insert 222 is provided with a second insert plate portion 224 that can enter and exit the second positioning slot 214. When the first insert plate portion 223 moves downward away from the first positioning slot 213 and the second insert plate portion 224 moves downward away from the second positioning slot 214, the first elongated insert 221 and the second elongated insert 222 move away from each other and elastically abut against the inner circumferential surface of the coil body 11. The above-described pin 220 facilitates the insertion of the spring coil 10, allows for a certain error in the inner diameter of the spring coil 10, and provides stable support for the spring coil 10.

[0042] See Figure 6 and Figure 7 In some embodiments of the present invention, in order to avoid the coil body 11 from deforming in the radial direction when the pin 220 acts on the coil body 11, the first long strip insert 221 and the second long strip insert 222 are respectively provided with a first arc surface 225 and a second arc surface 226 that match the inner circumferential surface of the coil body 11. The lower part of the first channel 211 is provided with a first arc slot 215 opposite to the first arc surface 225, and the lower part of the second channel 212 is provided with a second arc slot 216 opposite to the second arc surface 226. The height gap is located between the first arc surface 225 and the first arc slot 215 and between the second arc surface 226 and the second arc slot 216. During the downward movement of the pin 220 relative to the fixture body 210, the first arc surface 225 and the second arc surface 226 both abut against the inner circumferential surface of the coil body 11, causing the coil body 11 to move downward relative to the protruding end of the spring coil 10. The arrangement of the first arc slot 215 and the second arc slot 216 can limit the distance by which the protruding end of the spring coil 10 protrudes upward from the coil body 11.

[0043] See Figure 5 and Figure 7In some embodiments of the present invention, to prevent the pin 220 from accidentally disengaging from the spring coil 10, one end of the pin 220 is provided with an anti-disengagement head 270 connected to the first elongated insert 221 and the second elongated insert 222. To facilitate smoother insertion of the pin 220 into the spring coil 10, the end of the first elongated insert 221 away from the anti-disengagement head 270 is provided with a first guide slope 2211, and the end of the second elongated insert 222 away from the anti-disengagement head 270 is provided with a second guide slope 2221 opposite to the first guide slope 2211. A wide guide portion for inserting the partition 201 is defined between the first guide slope 2211 and the second guide slope 2221.

[0044] See Figure 6 In some embodiments of the present invention, the first limiting block 240 and the second limiting block 250 are respectively provided with a first guide hole 241 and a second guide hole 251. The fixture body 210 is provided with a guide through hole 217 opposite to the first guide hole 241 and the second guide hole 251. The guide rod 202 is sequentially passed through the first guide hole 241, the guide through hole 217 and the second guide hole 251. The two ends of the fixture body 210 are respectively provided with a first baffle 218 for preventing the first limiting block 240 from disengaging from the fixture body 210 and a second baffle 219 for preventing the second limiting block 250 from disengaging from the fixture body 210. The above structure achieves high precision in the relative sliding motion of the first limiting block 240 and the second limiting block 250, and can prevent the first limiting block 240 and the second limiting block 250 from disengaging from the fixture body 210.

[0045] See Figure 6 In some embodiments of the present invention, the fixture body 210 is provided with a supporting body 290 located between the first limiting block 240 and the second limiting block 250. The supporting body 290 is provided with an arcuate groove 291 that matches the outer circumferential surface of the coil body 11. It should be noted that before the spring coil 10 is formed, there is a certain distance between the outer circumferential surface of the coil body 11 and the arcuate groove 291. After the coil body 11 is moved downward into place, the outer circumferential surface of the coil body 11 abuts against the arcuate groove 291 to prevent the coil body 11 from bending and deforming.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
