Description

Technical Field

[0001] This application relates to the technical field of stranding machines, and in particular to a stranding machine for extremely fine alloy copper wire. Background Technology

[0002] Stranded wire is a multi-stranded metal wire, such as copper wire, aluminum wire, steel wire, electrical wires and cables with an outer insulation layer, and enameled wire, which are twisted together into a single multi-stranded wire using stranding equipment.

[0003] A utility model patent with Chinese patent authorization announcement number CN210489314U discloses a stranding machine for ultra-fine alloy copper wire, relating to the field of wire production technology. It aims to solve the technical problem of the complex structure of existing stranding machines. The key technical points of the solution include a frame on which a motor is mounted. A first wire clamp is rotatably connected to the outer wall of the motor's rotating shaft via a pin. A support frame is mounted on the frame, and an embedding groove is provided on the side wall of the support frame. A second wire clamp is rotatably connected to the embedding groove via a pin. The first wire clamp includes two first clamping plates, and the second wire clamp includes two second clamping plates. A first screw is threaded between the two first clamping plates, and a second screw is threaded between the two second clamping plates. The first and second wire clamps securely hold the ultra-fine alloy copper wire transported by a hydraulic cylinder. The motor drives the first wire clamp to rotate, thereby achieving the stranding of the ultra-fine alloy copper wire.

[0004] The following problems also exist in this solution: The device uses a first wire clamp and a second wire clamp to fix and hold the ultra-fine alloy copper wire, so as to realize the artificial control and adjustment of the twisting torque of the ultra-fine alloy copper wire. However, metal debris will be generated when the copper wire is twisted. These metal debris will fall onto the bottom frame and T-shaped disc during twisting, which is difficult to clean. Over time, this will easily affect the operating accuracy of the twisting machine.

[0005] Therefore, in order to solve the above problems, this application provides a stranding machine for ultra-fine alloy copper wire. Utility Model Content

Each of the chip collection boxes has a snap-fit ​​mechanism on both sides of its bottom. A chip suction mechanism is provided on one side of the T-shaped disc.

[0008] Preferably, the snap-fit ​​mechanism includes: Both sides of the bottom of the chip collection box are hinged with support rods. An arc-shaped plate is fixedly installed at the bottom of each of the two support rods. A square groove is opened through the top and bottom of each of the two arc-shaped plates. A screw is rotatably installed at the top and bottom of each of the two arc-shaped plates. A handle is fixedly installed at the end of each screw near the support rod. Both handles are adapted to the square groove. The screws on the two arc-shaped plates are arranged opposite to the square groove.

[0009] Preferably, the chip collection box has inclined surfaces on both sides.

[0010] Preferably, the dust collection mechanism includes: A mounting plate is provided on one side of the T-shaped disc. Two sliding grooves are provided on the side of the mounting plate near the frame. A slide rail is slidably installed in each of the two sliding grooves. Two sliding grooves are provided on the opposite sides of the two slide rails. A slider is slidably installed in each of the two sliding grooves. A chip collection box is fixedly installed on one side of the frame. A fan is fixedly installed on the top of the chip collection box. Chip suction pipes are connected to both sides of the chip collection box. Both chip suction pipes pass through the slider. A chip suction cover is connected to the end of each chip suction pipe near the T-shaped disc. A drive mechanism is provided in the sliding groove.

[0011] Preferably, a drawer is provided on one side of the chip collection box, the drawer passes through the chip collection box, the drawer slides in conjunction with the chip collection box, and a handle is fixedly installed on one side of the drawer.

[0012] Preferably, each of the two slide rails is fixedly mounted with an electric push rod on the side away from the mounting plate, and the output end of each of the two electric push rods is connected to one side of the slider.

[0013] Preferably, the drive mechanism includes: Both of the two slide rails are rotatably mounted with lead screws, both lead screws pass through slide rails and are threadedly connected to slide rails, the top ends of both lead screws pass through the top of mounting plates and are rotatably connected to mounting plates, and bevel gears are fixedly mounted on the top ends of both lead screws. A rotating shaft is provided on the opposite side of each of the two bevel gears, and a dual-axis motor is fixedly mounted between the two rotating shafts. The output end of the dual-axis motor is fixedly connected to the rotating shaft, and bevel gears are fixedly mounted on one end of each of the two rotating shafts, with the second bevel gear meshing with the first bevel gear.

[0014] Preferably, two support plates are fixedly installed on the top of the mounting plate, and both of the rotating shafts are rotatably connected to the support plates.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, a chip collection tray is installed at the bottom of the T-shaped disc and the stranding disc, allowing metal debris generated during the stranding of the ultra-fine alloy copper wire to fall into the bottom chip collection box. Simultaneously, metal debris near the sides of the stranding disc can enter the chip collection box downwards along the angle of the inclined surface, preventing debris from falling onto the frame and facilitating cleaning. Furthermore, a locking mechanism allows for the installation and removal of the chip collection tray. When needed, the support rods on both sides are rotated, causing the two arc-shaped plates to come closer together on the frame. Then, the handles on the two arc-shaped plates are passed through the square slots, and the handles are turned to rotate the screw. The side of the handle is aligned with the side of the arc-shaped plate, forming a cross shape with the square slot. After the screw rotates, it self-locks with the arc-shaped plate. When not needed, the handle is rotated to make it coaxial with the square slot, allowing the chip collection tray to be removed for cleaning.

[0016] In this invention, by setting up a fan, a dust collection mechanism, and a drive mechanism, the fan can generate a negative pressure airflow, which drives the dust collection pipe and dust collection hood to suck the iron filings that fall from both sides of the T-shaped disc into the dust collection box. The dust collection hood is close to the source of the debris, ensuring that the airflow can directly cover the T-shaped disc. The drive mechanism can drive the slide rail to move up and down, thereby driving the dust collection hood and dust collection pipe to move up and down. The electric push rod can push the slider to move left and right, thereby driving the dust collection pipe and dust collection hood to move left and right. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1, such as Figure 1-5 As shown, this utility model provides a stranding machine for ultra-fine alloy copper wire, including: a frame 1, a chip receiving box 2, a snap-fit ​​mechanism, and a chip suction mechanism; A T-shaped disc 8 is connected to one side of the top of the frame 1. Two stranded wire discs are provided on one side of the T-shaped disc 8. The bottom of the two stranded wire discs is connected to the frame 1. A chip collection box 2 is provided at the bottom of the T-shaped disc 8 adjacent to the two discs. Inclined surfaces 20 are provided on both sides of the chip collection box 2. A snap-fit ​​mechanism is provided on both sides of the bottom of the multiple chip collection boxes 2. A chip suction mechanism is provided on one side of the T-shaped disc 8. In this embodiment, the width of the multiple chip collection boxes 2 is equal to the width of the stranding reel, so that the metal chips generated during the stranding of the ultra-fine alloy copper wire can fall into the bottom chip collection box 2. At the same time, the metal chips near the two sides of the stranding reel can enter the chip collection box 2 downwards along the angle of the inclined surface 20, thereby collecting the metal chips of the stranded alloy copper wire, preventing the chips from falling onto the frame 1, and facilitating cleaning.

[0022] The locking mechanism includes: support rods 7 hinged to both sides of the bottom of the chip collection box 2; arc-shaped plates 6 fixedly installed at the bottom ends of the two support rods 7; square grooves 23 extending through the top and bottom of the two arc-shaped plates 6; screws 21 rotatably installed at the top and bottom of the two arc-shaped plates 6; and handles 22 fixedly installed at the ends of the two screws 21 near the support rods 7, with both handles 22 fitting into the square grooves 23. The screws 21 on the two arc-shaped plates 6 are arranged opposite to the square grooves 23, and the threads between the screws 21 and the arc-shaped plates 6 can achieve self-locking. The self-locking condition of the threads depends on the helix angle, the coefficient of friction, and the load. The self-locking condition of the threads can be calculated using the following formula: Self-locking condition = Coefficient of friction × tan(helix angle) ≥ 1. When this condition is met, the threaded connection is self-locking. The above content is all prior art; however, in practical applications, the corresponding self-locking angle can be set according to the coefficient of friction of the material, which will not be elaborated further here.

[0023] In this embodiment, the support rods 7 on both sides are rotated so that the two arc-shaped plates 6 are attached to the frame 1 and brought closer to each other. Then, the handles 22 on the two arc-shaped plates 6 are passed through the square slots 23. Then, the handles 22 are turned to drive the screw 21 to rotate. The side of the handle 22 is attached to the side of the arc-shaped plate 6 so that the handle 22 and the square slot 23 are in a cross shape. After the screw 21 rotates, it self-locks with the arc-shaped plate 6 so that the handle 22 will not shift its position. When not needed, the handle 22 is rotated so that the handle 22 and the square slot 23 are coaxial, and the chip collection tray can be removed for cleaning.

[0024] Example 2, as Figure 1-5 As shown, the chip collection mechanism includes: a mounting plate 3 on one side of a T-shaped disc 8; two sliding grooves 1 on the side of the mounting plate 3 near the frame 1, each containing a sliding rail 9; two sliding grooves 2 on the opposite sides of the two sliding rails 9, each containing a sliding block 17; a chip collection box 4 fixedly mounted on one side of the frame 1; a fan 5 fixedly mounted on the top of the chip collection box 4; and a drawer on one side of the chip collection box 4, which passes through the chip collection box 4 and slides with the chip collection box 4. In conjunction with this, a handle is fixedly installed on one side of the drawer, and two chip collection boxes 4 are connected to chip suction pipes 16 on both sides. The two chip suction pipes 16 are made of PU steel wire telescopic tubes and both chip suction pipes 16 pass through the slider 17. The ends of the two chip suction pipes 16 near the T-shaped disc 8 are connected to chip suction covers 19. Electric push rods 18 are fixedly installed on the side of the two slide rails 9 away from the mounting plate 3. The output ends of the two electric push rods 18 are connected to one side of the slider 17. A drive mechanism is provided in the slide groove.

[0025] In this embodiment, the fan 5 and the electric push rod 18 are started to generate negative pressure airflow, which drives the chip suction pipe 16 and the chip suction hood 19 to suck the iron chips that fall off both sides of the T-shaped disc 8 into the chip collection box 4. The dust suction hood is close to the chip source to ensure that the airflow can directly cover the T-shaped disc 8. The electric push rod 18 pushes the two sliders 17 to move, and the two sliders 17 drive the chip suction hood 19 and the chip suction pipe 16 to move, thereby sucking all the metal chips in the corners of the T-shaped disc 8 into the chip collection box 4.

[0026] The drive mechanism includes: two lead screws 10 rotatably mounted in two slide rails, both lead screws 10 passing through slide rails 9 and threadedly connected to slide rails 9; the top ends of both lead screws 10 passing through the top of mounting plate 3 and rotatably connected to mounting plate 3; bevel gears 11 fixedly mounted on the top ends of both lead screws 10; rotating shafts 15 on opposite sides of the two bevel gears 11; a dual-shaft motor 13 fixedly mounted between the two rotating shafts 15; the output end of the dual-shaft motor 13 fixedly connected to the rotating shafts 15; bevel gears 12 fixedly mounted on one end of each of the two rotating shafts 15, meshing with bevel gears 11; the two lead screws 10 rotating coaxially; two support plates 14 fixedly mounted on the top of mounting plate 3; and the two rotating shafts 15 rotatably connected to the support plates 14. The threads between the lead screws 10 and slide rails 9 can achieve self-locking, and the self-locking condition of the threads depends on the helix angle, friction coefficient, and load. The thread self-locking condition can be calculated using the following formula: Self-locking condition = Coefficient of friction × tan(helix angle) ≥ 1. When this condition is met, the threaded connection is self-locking. The above content refers to existing technology. In practical applications, the corresponding self-locking angle can be set according to the friction coefficient of the material, which will not be elaborated here.

[0027] In this embodiment, the dual-axis motor 13 can be started, which drives the rotating shaft 15 to rotate. The rotating shaft 15 drives the two bevel gears 12 to rotate, which in turn drives the two bevel gears 11 to rotate. The two bevel gears 11 drive the two lead screws 10 to rotate in the same direction. The rotation of the two lead screws 10 drives the slide rail 9 to move up and down, thereby driving the dust hood and dust suction pipe to move up and down. While performing dust suction, it does not affect the twisted alloy copper wire of the T-shaped disc 8.

[0028] Working principle: During use, rotate the support rods 7 on both sides to bring the two arc-shaped plates 6 close together on the frame 1. Then, pass the handles 22 on the two arc-shaped plates 6 through the square slots 23, and turn the handles 22 to drive the screw 21 to rotate. The side of the handle 22 is in contact with the side of the arc-shaped plate 6, so that the handle 22 and the square slot 23 form a cross shape. After the screw 21 rotates, it self-locks with the arc-shaped plate 6, so that the handle 22 will not shift its position, ensuring that the chip collection box 2 is located at the bottom of the stranding disc and the T-shaped disc 8. This allows the metal chips generated when the stranding disc and the T-shaped disc 8 are stranding the ultra-fine alloy copper wire to enter the chip collection box 2. After the T-shaped disc 8 has finished stranding the copper wire, start the fan 5, the dual-axis motor 13 and the electric push rod 18. The dual-axis motor 13 drives the rotating shaft 15 to rotate. The rotating shaft 15 drives two bevel gears 12 to rotate, which in turn drives two bevel gears 11 to rotate. The two bevel gears 11 drive two lead screws 10 to rotate in the same direction. The rotation of the lead screws 10 drives the slide rail 9 to move up and down, thereby driving the dust hood and dust suction pipe to move up and down. The fan 5 generates negative pressure airflow, which drives the dust suction pipe 16 and dust suction hood 19 to suck the iron filings that fall from both sides of the T-shaped disc 8 into the dust collection box 4. The dust suction hood is close to the source of the debris to ensure that the airflow can directly cover the T-shaped disc 8. The electric push rod 18 pushes two sliders 17 to move. The two sliders 17 drive the dust suction hood 19 and dust suction pipe 16 to move, thereby sucking all the metal filings in the corners of the T-shaped disc 8 into the dust collection box 4. Then, the handle can be used to pull out the drawer to process the metal filings inside.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
