A wire rod separating roller

Abstract

This invention discloses a wire rod separating roller, including a rotating shaft and guide discs. By mounting multiple sets of guide discs with inconsistent tooth heights side by side on the rotating shaft, it is ensured that the junction of each tooth is staggered, creating a slope between the teeth. At the same time, it can guide the wire rod that jumps out of the guide groove back into the guide groove, making it less likely for the wire rod to get stuck between two teeth. This ensures that when the wire rod separating roller is working, the guided wire rod is in the guide groove, preventing the wire rod from getting stuck between two guide discs and thus affecting the rotation of the guide discs.

Description

Technical Field

[0001] This invention relates to the field of steel processing, and in particular to a wire rod separating roller. Background Technology

[0002] When wire rod is stored for a long time, its surface reacts with moisture and air to form rust. Industrially, pickling or physical abrasion is commonly used to remove this rust. In a wire rod grinding device, before the wire rod enters the abrasion process section to remove surface rust, the wire rod is very densely wound, making grinding difficult. Therefore, a wire rod separating wheel is needed to guide the wire rod to disperse it evenly and make it coplanar, preventing the wire rods from stacking and leaving dead zones that the upper and lower abrasion rollers cannot reach. Based on these needs, a separating device has been invented, as follows:

[0003] refer to Figure 1 For example, in this separation device, multiple guide discs of the same shape and size are mounted on a rotating shaft 1 along its axial direction. A guide groove for guiding the disc strips is provided on the circumferential surface of the guide discs. Each guide disc can rotate independently along the circumferential direction of the rotating shaft. Circular grooves are provided on the opposing disc surfaces between the guide discs, and multiple balls 2 are provided in the circular grooves. Since the radius of the balls 2 is greater than the depth of the circular grooves 3, the middle part of the balls is outside the circular grooves 3, thus leaving a gap of 0.8mm-1mm between adjacent guide discs.

[0004] In practical application, the above-mentioned separation device can achieve the invention objective described in paragraph one, but a new problem has been discovered: the wire rod may detach from the groove during operation. The specific reasons are as follows:

[0005] Same reference Figure 1 For example, due to differences in wire rod toughness and movement speed, the wire rod may pop out of the groove 4 and get caught between the two guide plates 5. Since the wire rod is moving under tension, part of the vertical force of the wire rod will act on the gap between the two guide plates 5. In other words, the wire rod will gradually embed itself between the two guide plates, which will widen the gap between the adjacent guide plates, thus preventing the guide plates from rotating and working normally. Summary of the Invention

[0006] To address the aforementioned technical problems, the present invention aims to provide a novel wire rod separating roller. By sequentially mounting multiple sets of guide discs with varying tooth heights on a rotating shaft, the joints of each tooth are staggered, replacing the original flush mounting method and creating a slope between the teeth. Furthermore, the outer circumference of the aforementioned teeth is replaced with arc-shaped teeth instead of the original square teeth, reducing the stability of the wire rod above the teeth and allowing the wire rod to return to the groove better when ejected, preventing the wire rod from getting caught on the teeth.

[0007] The solution of this invention is implemented as follows:

[0008] A wire rod separating roller includes a rotating shaft, on which multiple guide disc assemblies are sleeved and mounted along the axial direction. Each guide disc assembly consists of a first guide disc and a second guide disc arranged side by side. The first and second guide discs are thin discs. The circumferential surface of the first guide disc is provided with a first guide groove for guiding the wire rod, and the two sides of the first guide groove form first teeth. The circumferential surface of the second guide disc is provided with a second guide groove for guiding the wire rod, and the two sides of the second guide groove form second teeth. Both the first and second guide discs can rotate independently along the circumferential direction of the rotating shaft. The outer circumference of the second guide disc is radially recessed so that the second teeth are lower than the first teeth, so as to form a staggered height at the junction of the first and second teeth.

[0009] Preferably, an arc-shaped transition is formed between the two sides of the first molar and the top surface of the first molar; similarly, an arc-shaped transition is formed between the two sides of the second molar and the top surface of the first molar.

[0010] The outer circumference of the aforementioned tooth is replaced with an arc-shaped tooth instead of the original square tooth, which weakens the stability of the wire rod when it stays above the tooth. At the same time, the arc-shaped tooth design also helps guide the wire rod back to the guide groove when it pops out of the corresponding guide groove.

[0011] Preferably, the second molar is 1-1.5 mm lower than the first molar.

[0012] Preferably, the second guide disk is rotatably connected to the rotating shaft via a second bearing. The first guide disk includes an outer disk and an inner disk. The inner disk is rotatably connected to the rotating shaft via a first bearing, and the inner disk rotates synchronously with the second guide disk. The inner diameter of the outer disk is larger than the outer diameter of the inner disk, thus forming an annular space between the inner and outer disks. A third bearing is embedded in this annular space. The outer disk rotates independently around the inner disk via the third bearing. The outer ring of the third bearing is interference-fitted with the inner ring of the outer disk. The two sides of the inner ring of the third bearing abut against the inner disk and the second guide disk, respectively, so that a preset distance is maintained between the second guide disk and the first guide disk.

[0013] The second guide plate is connected to the rotating shaft via a second bearing, allowing it to rotate independently around the shaft. The first guide plate comprises an inner and an outer plate. The inner plate is rotatably connected to the rotating shaft via a first bearing, allowing it to rotate independently around the main shaft, and it rotates synchronously with the first guide plate. Since the inner diameter of the outer plate is larger than the outer diameter of the inner plate, an annular space is formed between the inner and outer plates of the first guide plate. A third bearing is embedded within this annular space, allowing the outer plate to rotate independently around the inner plate. Because the second guide plate and the inner plate rotate synchronously, and the outer plate can rotate around the inner plate via the third bearing, the first and second guide plate outer plates do not affect each other when rotating around the main shaft. The inner ring of the third bearing is connected to the inner plate to achieve joint rotation. Because the inner ring of the third bearing abuts against the inner plate and the second guide plate, there is a gap between the first and second guide plate outer plates.

[0014] Preferably, the interference fit between the outer ring of the third bearing and the inner ring of the outer disk specifically means that: a convex ring extends radially inward on the side of the inner ring of the outer disk near the second guide plate; a groove is provided on the wall of the inner ring of the outer disk; after the outer ring of the third bearing is engaged with the inner ring of the outer disk, an elastic retaining ring is installed in the groove, and the outer ring of the third bearing is restricted between the convex ring and the elastic retaining ring. The outer disk has a convex ring, and by adding an elastic retaining ring between the inner circle of the outer ring of the third bearing and the outer disk of the second guide plate, the convex ring and the elastic retaining ring cooperate to restrict the axial movement of the outer ring of the third bearing; the interference fit between the outer ring of the third bearing and the inner ring of the outer disk also allows the outer ring of the third bearing and the outer disk of the second guide plate to rotate simultaneously.

[0015] The outer disk has a raised ring, and an elastic retaining ring is added between the outer ring of the third bearing and the inner circle of the outer disk of the second guide disk. The raised ring and the elastic retaining ring cooperate to restrict the movement of the outer ring of the third bearing in the axial direction. The interference fit between the outer ring of the third bearing and the inner ring of the outer disk allows the outer ring of the third bearing and the outer disk of the second guide disk to rotate simultaneously, avoiding relative movement and avoiding friction caused by the difference in speed between the two.

[0016] Preferably, the inner ring of the third bearing abuts against the inner plate and the second guide plate on both sides, respectively. This means that the inner plate extends outward on the side away from the second guide plate to form a stop portion, and the second guide plate shrinks at the position corresponding to the inner ring of the third bearing to form a clearance portion. The inner ring of the third bearing is sandwiched between the stop portion and the clearance portion so that a preset distance is maintained between the first guide plate and the second guide plate, and the inner ring of the third bearing is sleeved with the inner plate and the two are interference fit.

[0017] The inner disc extends outward on the side away from the second guide disc to form a stop portion that prevents the inner ring of the third bearing from deviating outward. The second guide disc is reduced at a position corresponding to the inner ring of the third bearing to form a clearance portion that facilitates the installation of the inner ring of the third bearing. The inner ring of the third bearing is installed between the outwardly extending stop portion of the inner disc and the clearance portion of the second guide disc. Since the inner ring of the third bearing is installed between the outwardly extending baffle of the inner disc and the clearance portion of the second guide disc, a gap is maintained between the outside of the first guide disc and the second guide disc. The inner ring of the third bearing is sleeved with the inner disc, and an interference fit is formed between the inner ring of the third bearing and the inner disc.

[0018] The principle and beneficial effects of the present invention, which adopts the above technical solution, are as follows:

[0019] This invention provides a wire rod separating roller, which replaces the flush guide discs with staggered guide disc groups. The guide disc groups consist of a first guide disc and a second guide disc with a height lower than the first guide disc, so each guide disc group forms uneven grooves. These guide disc groups are installed in an orderly manner along the axial direction on the circumferential surface of the rotating shaft in the order of first guide disc in front and second guide disc behind or second guide disc in front and first guide disc behind. This makes not only the grooves between each group of guide discs different, but also the surfaces between each adjacent pair of grooves are staggered, reducing the stress area on the grooves after the wire rod is ejected from the groove.

[0020] In addition, the guide disc teeth have been changed from square to curved, weakening the stability of the coil above the teeth. When the coil jumps out of the groove and hangs on the teeth, it cannot stay stable above the teeth because the diameter of the coil itself is much larger than the combined width of the first and second teeth at the connection point, as well as the gap width between the first and second teeth, and the actual contact area between the coil and the teeth is small. The new guide disc further reduces the area of ​​the teeth and creates a slope, making the contact area between the coil and the teeth even smaller and the stability even worse. In practical use, when the coil hangs on the teeth, under its own weight and tension, part of the downward force will force the coil to slide back into the groove along the slope, thus preventing the coil from getting caught on the teeth.

[0026] Detailed embodiments of the present invention

[0027] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0029] The terms “first,” “second,” and “third” are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] The specific implementation of this invention is as follows:

[0031] The invention will be further described below with reference to specific examples. Figure 3 , Figure 4 ;

[0032] This embodiment provides a wire rod separating roller with an uneven guide plate surface and no ball bearing structure. The wire rod separating roller of this embodiment includes a main shaft 7 and multiple guide plate groups 8 arranged side by side on the rotating shaft 7. In actual operation, the number of guide plate groups 8 can be increased or decreased according to the number of wire rods to be guided. Assuming that the number of wire rods is 24, 12 guide plate groups 8 can be arranged side by side on the rotating shaft 7 to meet the needs of guiding wire rods.

[0033] Each of the above-mentioned guide disk groups 8 consists of a first guide disk 10 and a second guide disk 9 connected side by side on the circumferential surface of the rotating shaft 7 via a first bearing 19 and a second bearing 15; the first guide disk 10 has a first guide groove 12 on its outer circumference, and first teeth 13 on both sides of the first guide groove 12; the second guide disk 9 has a second guide groove 11 on its outer circumference, and second teeth 14 on both sides of the second guide groove 11.

[0034] During the process of guiding the wire rod, the wire rod is located in the first guide groove 12 or the second guide groove 11.

[0035] In the radial direction, the first guide plate 10 is divided into an inner plate 17 and an outer plate 16 according to its internal and external structure. Since the inner diameter of the outer plate 16 is larger than the outer diameter of the inner plate 17, an annular space is formed between the outer plate 16 and the inner plate 17. A third bearing 18 is arranged in this annular space. In the axial direction, the left and right sides of the third bearing 18 abut against the first guide plate 10 and the second guide plate 9, respectively. The specific structure and connection method of the guide plate assembly 8 are described below:

[0036] The guide plate assembly 8 consists of a first guide plate 10 and a second guide plate 9. The first guide plate 10 is rotatably connected to the rotating shaft 7 via a first bearing 19, meaning the first guide plate 10 can rotate around the rotating shaft 7. The outer plate 16 is rotatably connected to the inner plate 17 via a third bearing 18, meaning the outer plate 16 can rotate around the inner plate 17. The inner plate 17 is rotatably connected to the rotating shaft 7 via the first bearing 19 and is clamped together with the second guide plate 9, rotating simultaneously, meaning the inner plate 17 can rotate synchronously around the rotating shaft 7 and the second guide plate 9. The second guide plate 9 is rotatably connected to the rotating shaft 7 via a second bearing 15, meaning the second guide plate 9 can rotate around the second bearing 15. Apart from the simultaneous rotation of the inner plate 17 and the second guide plate 9, the other guide plates can rotate independently around their respective bearings without being affected by other guide plates. The connection of the third bearing 18 between the first guide plate 9 and the second guide plate 10 will be explained below:

[0037] The outer disk 16 has a groove 21 at one end of its inner ring circumference. A protruding ring 20 extending vertically outwards from the outer disk 16 is located on the inner diameter circumference of the outer disk 16 near the second guide disk 9 in the same group. The third bearing 18 includes an outer ring 18a, an inner ring 18b, and a steel ball located between them. Furthermore, when the third bearing 18 is engaged with the inner ring of the outer disk 16, an elastic retaining ring 22 is fitted into the groove 21. At this time, the outer ring 18a abuts against the elastic retaining ring 22 and the protruding ring 20 on both sides, respectively.

[0038] The elastic retaining ring 22, which engages with the convex ring 20, prevents axial movement of the outer ring 18a of the third bearing. The interference fit between the outer ring 18a and the outer disk 16 ensures a tight connection, allowing them to rotate synchronously and preventing friction caused by shaking. A stop 23 extends radially outward from one end of the outer circumference of the inner disk 17 to prevent the third bearing 18 from shifting axially to one side. A corresponding clearance 24 on the second guide disk 9 prevents the third bearing 18 from shifting to the other side. The two sides of the inner ring 18b of the third bearing abut against the stop 23 and the clearance 24, respectively, ensuring that the third bearing 18 does not move laterally and maintaining the clearance between the outer disk 16 and the second guide disk 9.

[0039] During operation, the above-mentioned structural design allows the second guide plate 9 and the first guide plate 10 to rotate independently, preventing one plate from getting stuck and affecting the rotation of the other. At the same time, since the second tooth 14 is recessed relative to the first tooth 13, a stepped descent is formed between the two guide plates in the same guide plate group, reducing the contact area of ​​the steel wire at this point, making it less likely for the steel wire to get stuck here.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention 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 invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
