Wire length cutting device

Abstract

This utility model relates to the field of wire length cutting. Its purpose is to provide a wire length cutting device that solves the problem of repeated wire cutting. The cutter and the pressure block are mounted on the cutting seat. The pressure block is located above the cutter and extends above the rotating ring. The cutting seat has a contact surface.

Because the motor indirectly drives the hollow column and the rotating ring to rotate, the rotating ring drives the wire to rotate along the contact surface. The excessively long portion of the wire at the bottom impacts the cutting surface and is broken off. The product groove and the contact surface restrict the wire, and the pressure block prevents the wire from jumping up. In this way, the wire is cut into shape in one operation without repeated cutting, thus solving the problem of repeated wire cutting.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] like Figure 1 and Figure 2 and Figure 3 As shown, a wire length cutting device includes a loading assembly 1, a cutting assembly 2, and a driving assembly 3. The loading assembly 1 includes a carrier plate 11, a hollow column 12, a ratchet 16, and a pawl 17. The hollow column 12 is rotatably mounted on the carrier plate 11. The ratchet 16 and the hollow column 12 are rotatably mounted separately. The ratchet 16 is rotatably mounted on the hollow column 12. A swivel ring 13 is provided on the axial end of the ratchet 16. The swivel ring 13 is fixed to the ratchet 16 by bolts. The swivel ring 13 is mounted on the hollow column 12. A product groove 14 is provided on the swivel ring 13. The product groove 14 passes through both axial ends of the swivel ring 13. The outer diameter of the swivel ring 13 is larger than the outer diameter of the ratchet 16.

[0019] A drive block 15 is provided around the hollow column 12, and a pawl 17 is provided on the drive block 15. The pawl 17 is fixed to the drive block 15 by bolts. The ratchet 16 has ratchet teeth 160 around its circumference. The end of the pawl 17 is used to push the ratchet teeth 160. The product groove 14 is used to place the wire 5. The top end of the wire 5 has an end 50. The end 50 overlaps the top end of the product groove 14 and the upper end face of the swivel ring 13, so that the wire 5 will not fall out of the product groove 14.

[0020] The cutting assembly 2 includes a cutting seat 21, a cutter 22, and a pressure block 23. The cutting seat 21 is disposed on the outer edge of the rotating ring 13 and is fixed to the carrier plate 11 by bolts. The cutter 22 and the pressure block 23 are disposed on the cutting seat 21 and are respectively fixed to the cutting seat 21 by bolts. The pressure block 23 is located above the cutter 22 and extends above the rotating ring 13. The cutting seat 21 has a contact surface 24 that extends along the radial outer periphery of the rotating ring 13. The contact surface 24 maintains a gap with the radial outer periphery of the rotating ring 13, but the wire 5 cannot fall out of this gap.

[0021] The cutter 22 has a cutting surface 220. The rotating ring 13 drives the wire 5 to rotate. The cutting surface 220 is located below the rotation path of the product groove 14. The bottom end of the wire 5 is located at the outer edge of the bottom end of the product groove 14. The wire 5 is longer than the product groove 14. The excess length of the wire 5 hits the cutting surface 220 and is broken. The wire 5 is cut. The pressure block 23 is located above the rotation path of the product groove 14. When the excess length of the wire 5 hits the cutting surface 220, the pressure block 23 can prevent the wire 5 from jumping up. The end 50 is located below the pressure block 23.

[0022] After the excess length at the bottom of the wire 5 is cut off, the swivel 13 drives the wire 5 to rotate until the wire 5 leaves the bonding surface 24, at which point the wire 5 is removed.

[0023] The cutting assembly 2 also includes a first guide plate 25 and a second guide plate 26. The first guide plate 25 and the second guide plate 26 are disposed on the cutting seat 21. The first guide plate 25 is located above the second guide plate 26. The first guide plate 25 has a first guide surface 250, and the second guide plate 26 has a second guide surface 260. The first guide surface 250 and the second guide surface 260 are spliced ​​together with the mating surface 24. The first guide surface 250 and the second guide surface 260 extend along the radial outer periphery of the rotating ring 13.

[0024] Furthermore, the first ends of the first guide surface 250 and the second guide surface 260 are attached to the discharge end of the clamping groove 44, and the second ends of the first guide surface 250 and the second guide surface 260 are spliced ​​together with the contact surface 24. The first guide plate 25 and the second guide plate 26 are respectively fixed to the cutting seat 21 by bolts.

[0025] The drive assembly 3 includes a motor 31, a disk 32, and a connecting rod 33. The motor 31 is mounted on the carrier plate 11 and is fixed to the carrier plate 11 by bolts. The disk 32 is mounted on the drive end of the motor 31 and is fixed to the drive end of the motor 31 by bolts. The two ends of the connecting rod 33 are rotatably connected to the disk 32 and the drive block 15, respectively. In this example, the two ends of the connecting rod 33 are ball-head connected to the disk 32 and the drive block 15, respectively. The motor 31 drives the disk 32 to rotate, the disk 32 drives the connecting rod 33 to rotate, the connecting rod 33 drives the drive block 15 to rotate, and the drive block 15 drives the hollow column 12 and the pawl 17 to rotate. The pawl 17 can drive the ratchet 160 and the ratchet wheel 16 to rotate.

[0026] Because the disc 32 rotates in a circle, the drive block 15 can drive the hollow column 12 and the pawl 17 to rotate in reverse. When the hollow column 12 and the pawl 17 rotate in reverse, the ratchet 16 and the ring 13 remain stationary. The drive block 15 continuously drives the hollow column 12 and the pawl 17 to rotate in both directions, while the ratchet 16 and the ring 13 can only rotate in one direction.

[0027] like Figure 4 and Figure 5 and Figure 6 As shown, the cutting seat 21 is provided with an upper groove 251 and a lower groove 261. The upper groove 251 is located above the lower groove 261. A first guide plate 25 is disposed in the upper groove 251 and a second guide plate 26 is disposed in the lower groove 261. The first guide plate 25 and the second guide plate 26 are arranged side by side. The first guide plate 25 is flush with the upper surface of the cutting seat 21.

[0028] The cutting assembly 2 also includes a limiting spring 27, a limiting block 28, and a limiting rod 29. The cutting seat 21 is provided with a through hole 210. The limiting spring 27 is disposed in the through hole 210. The limiting rod 29 is threadedly connected to the through hole 210. The two ends of the limiting spring 27 are respectively connected to the limiting block 28 and the limiting rod 29. The limiting block 28 is on the same side as the contact surface 24. The through hole 210 includes a circular hole and a square hole that communicate with each other. The limiting spring 27 and the limiting rod 29 are located in the circular hole, and the limiting block 28 can return to the square hole.

[0029] The limiting block 28 is configured such that the rotating ring 13 drives the wire 5 to rotate, and when the wire 5 hits the cutting surface 220, the wire 5 also presses against the limiting block 28. Since there is a gap between the contact surface 24 and the rotating ring 13, under the elastic force of the limiting spring 27, the limiting block 28 can press against the wire 5 to prevent the wire 5 from vibrating and tilting when it hits the cutting surface 220.

[0030] The cutting assembly 2 also includes a heightening plate 201. The heightening plate 201 has an inlet surface 202. The heightening plate 201 is fixed to the upper surface of the cutting seat 21 by bolts. After the wire 5 turns to the area covered by the mating surface 24, the end 50 overlaps the top of the product groove 14 and the upper surface of the cutting seat 21 respectively. The end 50 slides from the inlet surface 202 onto the heightening plate 201, which is equivalent to raising the wire 5. Then the excess length of the bottom end of the wire 5 hits the cutting surface 220. By replacing the heightening plate 201 with different thicknesses, it is possible to cut wires 5 of different lengths.

[0031] Additionally, the pressure block 23 is provided with a relief groove 230, which can avoid the raised end 50.

[0032] It also includes a feeding rack 4, which includes a first clamping bar 41, a second clamping bar 42, and a support rod 43. The support rod 43 is set on the carrier plate 11 and is fixed to the carrier plate 11 by bolts. The first clamping bar 41 and the second clamping bar 42 are arranged side by side at an angle on the support rod 43 and are fixed to the support rod 43 by bolts respectively. A clamping groove 44 is formed between the first clamping bar 41 and the second clamping bar 42. The clamping groove 44 is used to place wires 5. The discharge end of the clamping groove 44 is aligned with the radial outer circumference of the rotating ring 13. In practice, there is always a product slot 14 aligned with the discharge end of the clamping groove 44. Multiple wires 5 are placed in the clamping groove 44 with adjacent ends 50 touching each other. Thus, there is a gap between adjacent wires 5. The ends 50 overlap the first clamping bar 41 and the second clamping bar 42, and the wires 5 can slide freely in the clamping groove 44.

[0033] The loading assembly 1 also includes a central column 10, a bearing cover plate 18, a partition plate 19, and a cylinder 101. The central column 10 is mounted on the carrier plate 11. The hollow column 12 and the bearing cover plate 18 are rotatably mounted on the central column 10. The central column 10 passes upward through the hollow column 12. The top of the central column 10 is higher than the top of the hollow column 12. The bearing cover plate 18 is located above the rotating ring 13. The rotating ring 13 and the ratchet 16 are mounted on the central column 10. A bearing is also mounted on the central column 10. The hollow column 12 is fixed to the bearing by bolts.

[0034] The cylinder 101 is located on the outer edge of the rotating ring 13, and the partition plate 19 is located on the bearing cover plate 18. The partition plate 19 is welded to the bearing cover plate 18 and is also rotatably connected to the drive end of the cylinder 101. The partition plate 19 extends to the radial outer edge of the rotating ring 13. After the wire 5 is placed in the product slot 14, the cylinder 101 drives the partition plate 19 to protect the outer edge of the radial opening end of the product slot 14. The motor 31 indirectly drives the hollow column 12 to rotate at a set angle. The hollow column 12 rotates the angle between two adjacent product slots 14, so the ratchet 16 and the rotating ring 13 also rotate the angle between two adjacent product slots 14, so that the radial opening end of the product slot 14 is aligned with the mating surface 24. Thus, an empty product slot 14 appears on the rotating ring 13. This empty product slot 14 is located within the partition range of the partition plate 19.

[0035] Motor 31 then indirectly drives hollow column 12 to reverse, ratchet 16 and swivel ring 13 remain stationary, cylinder 101 drives partition plate 19 to reset, and wire 5 is placed into the empty product slot 14 again, and the above steps are repeated.

[0036] The partition plate 19 includes a bent portion 191 and a partition piece 192 connected to each other. The bent portion 191 is bent and connected to the bearing cover plate 18. The bent portion 191 is welded to the bearing cover plate 18. The bent portion 191 is also rotatably connected to the drive end of the cylinder 101. The partition piece 192 extends circumferentially along the rotating ring 13. A distance is maintained between the partition piece 192 and the radial outer periphery of the rotating ring 13. This distance prevents the wire 5 from falling off. The inner side of the partition piece 192 can mate with the mating surface 24 during rotation.

[0037] The loading assembly 1 also includes a bracket 102 and a push rod 103. The bracket 102 is mounted on the carrier plate 11, and the cylinder 101 is mounted on the bracket 102. The push rod 103 is connected to the drive end of the cylinder 101 and is rotatably connected to the partition plate 19. In fact, the push rod 103 is rotatably connected to the bending part 191. The bracket 102 is fixed to the carrier plate 11 by bolts, and the cylinder 101 is rotatably connected through the bracket 102.

[0038] When the first wire 5 slides into the product slot 14, the second wire 5 also slides down. The cylinder 101 indirectly drives the separator 192 to move. The separator 192 passes between two adjacent wires 5. The separator 192 can prevent the wires 5 in the product slot 14 from falling off and can also prevent the second wire 5 from continuing to slide down, thus avoiding friction between the second wire 5 and the rotating ring 13.

[0039] like Figure 7 and Figure 8As shown, a groove 130 is provided on the radial outer periphery of the rotating ring 13. The axial ends of the groove 130 have a first collar 131 and a second collar 132. The groove 130 is located between the first collar 131 and the second collar 132. The product groove 14 is provided on the groove 130, the first collar 131 and the second collar 132. The mating surface 24 extends into the groove 130.

[0040] The limiting block 28 is located in the annular groove 130. The upper and lower ends of the limiting block 28 are respectively connected to the first shaft collar 131 and the second shaft collar 132. In this way, the limiting block 28 will not jump due to vibration. The first shaft collar 131 and the second shaft collar 132 also have a limiting effect on the limiting block 28.

[0041] The radial outlet end of the product groove 14 has a first rotating surface 141 and a second rotating surface 142. The first rotating surface 141 and the second rotating surface 142 are located on the same side of the radial outlet end of the product groove 14. The first rotating surface 141 is disposed on the first collar 131, and the second rotating surface 142 is disposed on the second collar 132. Both the first rotating surface 141 and the second rotating surface 142 are extended. After the wire 5 moves away from the contact surface 24, the wire 5 rotates out while in contact with the first rotating surface 141 and the second rotating surface 142. The wire 5 falls out of the product groove 14. The first rotating surface 141 and the second rotating surface 142 first approach the contact surface 24, and at the same time, the first rotating surface 141 and the second rotating surface 142 also first move away from the contact surface 24.

[0042] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
