Description

Technical Field

[0001] This utility model relates to the field of wire feeding technology for screw processing, and specifically to a wire feeding device for screw processing. Background Technology

[0002] Screw processing generally uses metal wire as raw material. When feeding metal wire, a feeding rack is usually used. The metal wire is placed on the limiting frame in the feeding rack. When one end of the metal wire is fed, the turntable at the top of the feeding rack will drive the metal wire to rotate together.

[0003] The existing feeding racks have high limit frames, requiring the wire to be lifted to a high position when coiled metal wire is placed on the limit frame. This makes it impossible to use a crane to assemble the metal wire in some small workshops. At the same time, the positioning rings on the existing feeding racks are not easy to adjust in height. Different models of screw forming machines have different feed inlet heights. If the height of the positioning ring cannot be adjusted, the output height of the metal wire cannot be kept consistent with the feed inlet height of the screw forming machine, which will affect the feeding. Therefore, a wire feeding device for screw processing is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a wire feeding device for screw processing in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A wire feeding device for screw processing includes a base frame, a rotating shaft rotatably mounted on the upper end of the base frame, a turntable fixedly mounted on the top of the rotating shaft, a placement plate fixedly mounted on the top of the turntable, three movable rods slidably mounted on the placement plate, a common positioning ring fixedly mounted on the top of the three movable rods, several through holes opened on the movable rods, a pull rod inserted into one of the through holes, one end of the pull rod extending into the placement plate, a limiting component for limiting the displacement of the three pull rods provided in the placement plate, a limiting frame slidably mounted in the placement plate, an annular plate fixedly mounted at the bottom of the limiting frame and at the bottom of the placement plate, a limiting rod inserted into the turntable, and a fixing component for fixing the limiting rod provided in the limiting rod.

[0007] Furthermore, the limiting component includes three limiting grooves, all of which are formed in the placement plate and located at the bottom of the three pull rods respectively. A limiting block is slidably installed in the limiting groove, one end of the limiting block extends into the pull rod, and a second spring is fixedly installed at the bottom of the limiting block and tightly welded to the inner wall of the limiting groove. One end of the limiting block is slidably connected to the pull rod.

[0008] Furthermore, the fixing component includes a slide groove, which is formed inside the limiting rod. A slider is slidably installed inside the slide groove. One end of the slider passes through the bottom of the slide groove and extends to the outside. A first spring is fixedly installed on the top of the slider and tightly welded to the inner wall of the slide groove. One side of the slider contacts the peripheral side wall of the turntable.

[0009] Furthermore, the annular plate is located between the placement plate and the limiting rod, with the top and bottom of the annular plate contacting the bottom of the placement plate and the top of the limiting rod, respectively.

[0010] Furthermore, the through holes on the movable rod are linearly and equally spaced.

[0011] Furthermore, one end of the pull rod is inserted into the placement plate.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This wire feeding device for screw processing, through the cooperation of the movable rod, through hole, pull rod and limiting component, ensures that the positioning ring can be adjusted to different heights, thereby adapting to different models of screw forming machines and ensuring that the output height of the metal wire can be consistent with the height of the screw forming machine's feed inlet.

[0014] 2. This wire feeding device for screw processing, through the cooperation of the limiting frame, ring plate, limiting rod and fixing components, ensures that the height of the limiting frame can be adjusted. When the coiled metal wire is placed on the top of the placement tray, it only needs to be lifted above the positioning ring, which reduces the lifting height of the metal wire. It can also be used in some factories with small spaces. At the same time, the height of the positioning ring can also be adjusted to the lowest point, thereby reducing the lifting height of the metal coil and making it more convenient to use.

[0029] like Figures 1 to 8 As shown, a wire feeding device for screw processing includes a base frame 1. A rotating shaft 6 is rotatably mounted on the upper end of the base frame 1. A turntable 7 is fixedly mounted on the top of the rotating shaft 6. A placement plate 2 is fixedly mounted on the top of the turntable 7. Three moving rods 3 are slidably mounted on the placement plate 2. The top of the three moving rods 3 is fixedly mounted with the same positioning ring 4. Several through holes 13 are opened on the moving rods 3. A pull rod 17 is inserted into one of the through holes 13. One end of the pull rod 17 extends into the placement plate 2. The placement plate 2 is provided with a limiting component for limiting the displacement of the three pull rods 17. Figure 7 As shown, the limiting assembly includes three limiting grooves 14, all of which are opened in the placement plate 2 and are respectively located at the bottom of the three pull rods 17. A limiting block 16 is slidably installed in the limiting groove 14, one end of the limiting block 16 extends into the pull rod 17, and a second spring 15 is fixedly installed at the bottom of the limiting block 16 and tightly welded to the inner wall of the limiting groove 14. One end of the limiting block 16 is slidably connected to the pull rod 17.

[0030] More specifically, when the height of the positioning ring 4 needs to be adjusted to fit different models of screw forming machines, the operator can first pull the pull rod 17 outward. At this time, the limit block 16 will be squeezed and will move downward, and the second spring 15 will be squeezed and will contract until one end of the pull rod 17 is completely removed from the placement plate 2 and one of the through holes 13. Then, after all three pull rods 17 are pulled out, the three moving rods 3 will be released from fixation. The operator can then move the positioning ring 4 upward. When the positioning ring 4 is moved to the appropriate position, the three pull rods 17 will be returned to their original positions. At this time, the pull rod 17 will be located in the corresponding through hole 13. Then, one end of the metal wire can be placed on the positioning ring 4 to keep it horizontal with the feed port of the screw forming machine.

[0031] A limiting frame 5 is slidably installed inside the placement tray 2. An annular plate 8 is fixedly installed at the bottom of the limiting frame 5 and at the bottom of the placement tray 2. A limiting rod 9 is inserted into the turntable 7, and a fixing component for fixing the limiting rod 9 is provided inside the limiting rod 9; for example... Figure 3 and Figure 4As shown, the fixing component includes a slide groove 11, which is opened inside the limiting rod 9. A slider 10 is slidably installed inside the slide groove 11. One end of the slider 10 passes through the bottom of the slide groove 11 and extends to the outside. A first spring 12 is fixedly installed on the top of the slider 10 and tightly welded to the inner wall of the slide groove 11. One side of the slider 10 contacts the peripheral side wall of the turntable 7.

[0032] More specifically, during use, when placing metal wire, the operator can first press the slider 10 upwards by hand. The slider 10 will move upwards within the slide groove 11. At this time, the first spring 12 will be compressed and contract until the slider 10 is fully inserted into the slide groove 11. Then, the operator can pull the limiting rod 9 to remove it from the turntable 7. The annular plate 8 will then be released from its fixed position. Next, the annular plate 8 and the limiting frame 5 can be moved downwards to their lowest position. Subsequently, the crane can be operated to place the metal wire on top of the placement tray 2. During this placement process, the crane only needs to lift the wire to the designated height. The ring can be placed above ring 4 without being hoisted too high, making it more convenient for smaller factories. After the metal wire is placed, the workers can push the ring plate 8 and the limiting frame 5 upward so that the top of the ring plate 8 contacts the bottom of the placement tray 2. Then, the limiting rod 9 is inserted into the turntable 7 again. Under the action of the rebound force of the first spring 12, the first spring 12 will drive the slider 10 downward so that the slider 10 moves to the outside and contacts the turntable 7, thereby fixing the ring plate 8. At this time, the ring plate 8 will also be fixed by the limiting rod 9, and the limiting frame 5 will be located inside the metal wire.

[0033] like Figure 2 As shown, the annular plate 8 is located between the placement plate 2 and the limiting rod 9, with the top and bottom of the annular plate 8 contacting the bottom of the placement plate 2 and the top of the limiting rod 9, respectively.

[0034] More specifically, this ensures that the limiting rod 9 can fix the position of the annular plate 8, preventing the annular plate 8 from shifting downwards or upwards.

[0035] like Figure 7 As shown, the through holes 13 on the moving rod 3 are linearly and equally spaced.

[0036] More specifically, the through holes 13 on the moving rod 3 are linearly and equally spaced to ensure that the positioning ring 4 can be adjusted to different heights to adapt to different models of screw forming machines.

[0037] like Figure 7 As shown, one end of the pull rod 17 is inserted into the placement plate 2.

[0038] More specifically, ensure that one end of the lever 17 can be inserted into the placement tray 2.

[0039] In summary: When using the device, if it is necessary to place the metal wire, the operator can first press the slider 10 upwards by hand. The slider 10 will move upwards within the slide groove 11. At this time, the first spring 12 will be compressed and contract until the slider 10 is fully inserted into the slide groove 11. Then, the operator can pull the limiting rod 9 to remove it from the turntable 7. The annular plate 8 will then be released from its fixed position. Next, the annular plate 8 and the limiting frame 5 can be moved downwards to their lowest position. Subsequently, the crane can be operated to place the metal wire on top of the placement tray 2. During this placement process, the crane only needs to lift the wire to the positioning ring 4. The wire can be placed directly above the metal wire without needing to be hoisted too high, making it more convenient for smaller factories. After the metal wire is placed, the workers can push the annular plate 8 and the limiting frame 5 upwards so that the top of the annular plate 8 contacts the bottom of the placement tray 2. Then, the limiting rod 9 is inserted into the turntable 7 again. Under the action of the rebound force of the first spring 12, the first spring 12 will drive the slider 10 downwards, so that the slider 10 moves to the outside and contacts the turntable 7, thereby fixing the annular plate 8. At this time, the annular plate 8 will also be fixed by the limiting rod 9, and the limiting frame 5 will be located inside the metal wire.

[0040] When the height of the positioning ring 4 needs to be adjusted to fit different models of screw forming machines, the operator can first pull the pull rod 17 outward. At this time, the limit block 16 will be squeezed and will move downward, and the second spring 15 will be squeezed and will contract until one end of the pull rod 17 is completely removed from the placement plate 2 and one of the through holes 13. Then, after all three pull rods 17 are pulled out, the three moving rods 3 will be released from fixation. The operator can then move the positioning ring 4 upward. When the positioning ring 4 is moved to the appropriate position, the three pull rods 17 will be returned to their original positions. At this time, the pull rod 17 will be located in the corresponding through hole 13. Then, one end of the metal wire can be placed on the positioning ring 4 to keep it horizontal with the feed port of the screw forming machine.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
