Description

Technical Field

[0001] The utility model relates to an I-shaped wheel which can be applied to laser wire cutting. Background Art

[0002] The I-shaped wheel is a tool used to wind metal wire or wire rope. It is called an I-shaped wheel because of its traditional shape of an "I" character. The metal wire on the I-shaped wheel is generally neatly wound on the wire winding cylinder of the I-shaped wheel as the wheel rotates; and to remove the metal wire on the I-shaped wheel, the wheel also needs to rotate in the opposite direction to release the metal wire outward.

[0003] However, when the metal wire wound on the I-shaped wheel needs to be scrapped for various reasons, if the wire is still unloaded by rotating the I-shaped wheel, a special machine is required, which is time-consuming and labor-intensive. Therefore, the metal wire wound on the I-shaped wheel is generally cut directly by cutting.

[0004] When cutting the scrapped metal wire on the I-shaped wheel, flame cutting is traditionally used. However, due to the high temperature of the flame, in order to avoid damaging the I-shaped wheel, that is, the I-shaped wheel needs to be reused after removing the waste wire, the cutting operation will be carried out away from the flange of the I-shaped wheel and one end of the wire winding cylinder. Most of the metal wire in the middle is removed by flame cutting, and the remaining part is removed by manual shearing, which is time-consuming and labor-intensive.

[0005] With the development of laser cutting technology, many companies currently use laser cutting to remove waste wire from I-shaped wheels. Because laser cutting can accurately locate the flange position, it can avoid the flange position and then cut; but in order to cut the waste wire, the laser cutting power is also high, so when cutting the innermost waste wire, it will also leave laser marks on the surface of the winding cylinder, which requires the I-shaped wheel to be repaired before it can be reused; or similar to flame cutting, the innermost part of the waste wire remains for manual shearing and removal, which is also time-consuming and laborious. In view of the above situation, the laser cutting technology can be improved, but the implementation of technical transformation is difficult.

[0006] At the same time, combined with the characteristics of laser cutting, the I-shaped wheel itself can be improved to make it resistant to laser cutting, so that it can be conveniently used in situations where laser cutting of waste wire is required, thereby improving the cutting and removal efficiency of waste wire, allowing the I-shaped wheel to be recycled as soon as possible for easy reuse. Utility Model Content

[0007] The utility model aims to provide a durable I-shaped wheel capable of laser cutting wires. A laser-resistant strip is embedded on a wire winding cylinder, and the laser-resistant strip bears the cutting of the laser beam without obvious damage on the surface, so that the I-shaped wheel can be quickly reused after laser cutting wires, and is convenient to use.

[0008] To achieve the above-mentioned utility model purpose, the present utility model provides a durable spool capable of laser wire cutting, which has a wire-winding cylinder in a cylindrical shape, and a laser-resistant strip is embedded on the outer surface side of the wire-winding cylinder;

[0009] The wire-winding cylinder is axially provided with an embedding groove, and the laser-resistant strip is embedded in the embedding groove. The embedding groove and the laser-resistant strip are parallel to the axis of the wire-winding cylinder and penetrate in the axial direction of the wire-winding cylinder.

[0010] As a further improvement of the present utility model, the thickness H of the laser-resistant strip is 1-3 mm, and the width W is 3-10 mm.

[0011] As a further improvement of the present utility model, marks are provided at both ends of the spool, and the marks are aligned with the laser-resistant strip.

[0012] As a further improvement of the present utility model, an adhesive is provided between the embedding groove and the laser-resistant strip.

[0013] As a further improvement of the present utility model, the embedding groove is in a dovetail shape, and the laser-resistant strip is a trapezoidal strip; the laser-resistant strip fits with the dovetail-shaped embedding groove.

[0014] As a further improvement of the present utility model, after the laser-resistant strip is installed in place in the embedding groove, both sides of the laser-resistant strip are flush with the arc surface angle of the wire-winding cylinder.

[0015] As a further improvement of the present utility model, the laser strip is fixed to the bottom of the embedding groove of the wire-winding cylinder through a rivet;

[0016] A first rivet hole is provided on the laser-resistant strip, and a second rivet hole is provided at the bottom of the embedding groove of the wire-winding cylinder;

[0017] The first rivet hole is aligned with and penetrates through the second rivet hole; the rivet is fixed in the first rivet hole and the second rivet hole at the same time.

[0018] As a further improvement of the present utility model, flanges are provided at both ends of the spool; flange embedding grooves are provided along the diameter direction on the inner sides of the two flanges; the flange embedding grooves abut against the surface of the wire-winding cylinder, and the flange embedding grooves communicate with the embedding grooves on the surface of the wire-winding cylinder;

[0019] Flange laser-resistant strips are embedded in the flange embedding grooves;

[0020] The flange laser-resistant strips on both sides are connected to the laser-resistant strips embedded on the surface of the wire-winding cylinder.

[0021] Furthermore, the cross-sectional shape of the flange embedding groove is the same as the cross-sectional shape of the embedding groove on the surface of the wire-winding cylinder;

[0022] The cross-sectional shape of the flange laser-resistant strip is the same as the cross-sectional shape of the laser-resistant strip embedded on the surface of the wire-winding cylinder.

[0023] Further, the opening end of the flange mounting groove is located at the edge of the flange;

[0024] The laser-resistant strip of the flange is flush with the outer circumference of the flange.

[0025] The durable I-shaped wheel capable of laser cutting of the utility model uses metal or non-metal as laser-resistant strips, which are embedded on the outer surface of the wire winding cylinder for the laser beam to cut through without causing obvious damage. Therefore, after the laser cutting is completed, the I-shaped wheel can be quickly reused.

[0026] After the I-shaped wheel has been laser cut and reused for many times, the laser beam cutting resistance of the laser-resistant strip will decrease. The I-shaped wheel can be returned to the factory, the laser-resistant strip can be removed and replaced with a new one, and then it can be used again.

[0027] The durable I-wheel capable of laser wire cutting of the utility model has made structural improvements to the existing I-wheel so as to meet the requirements of laser wire cutting operations. When cutting wire, the laser-resistant strip can be directly cut, so that all the metal wires on the wire winding cylinder are cut off, eliminating the need for subsequent manual operations. The laser cutting effect is high, and the I-wheel can also be quickly put back into use, with a high recycling rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0042] The utility model provides a durable I-shaped wheel capable of laser cutting, and its overall structure is as follows Figure 1 , Figure 2 As shown, for various styles of I-shaped wheels, there is a wire winding cylinder 1, flanges 5 may be provided at both ends of the wire winding cylinder 1, and a pin 6 may be provided on the flange 5. The improvement of the utility model is that a laser-resistant strip 2 is embedded on the outer surface of the wire winding cylinder 1.

[0043] The laser-resistant strip 2 has the property of being resistant to laser cutting. For example, metal strips such as aluminum strips, aluminum alloy strips, copper strips, copper alloy strips, etc. with smooth surfaces can be used. Since the smooth surface of the metal can emit laser beams, it is resistant to laser cutting. Or polyoxymethylene / POM plastic strips and polytetrafluoroethylene / PTFE plastic strips can be used. They have good stability. The temperature generated when the laser beam cuts the metal wire causes the surface plastic to melt slightly, but it will automatically recover as it cools down and will not affect continued use.

[0044] Further Figure 3 , Figure 4 , Figure 5 , Figure 6As shown in the figure, the wire-winding cylinder 1 is a thick-walled (thickness greater than 4 mm) metal cylinder, with an embedding groove 11 axially opened. If the wall thickness is too thin, the embedding groove 11 cannot be machined, or the strength will be reduced after machining, making it easy to damage. Inside the embedding groove 11, a laser-resistant strip 2 is embedded. The thickness H of the laser-resistant strip is 1 - 3 mm, and the width W is 3 - 10 mm. Since the laser beam generally runs straight during laser wire cutting, the embedding groove 11 and the laser-resistant strip 2 are parallel to the axis of the wire-winding cylinder 1 and run through the axis direction of the wire-winding cylinder 1, that is, from the inner side of one side flange 5 to the inner side of the other side flange 5.

[0045] To ensure that the laser-resistant strip 2 does not fall off from the embedding groove 11 during use, an adhesive, glue, etc. can be provided between the embedding groove 11 and the laser-resistant strip 2.

[0046] Furthermore, as Figure 4 、 Figure 5 shown in the figure, the embedding groove 11 and the laser-resistant strip 2 are in the shape of a dovetail / trapezoid, that is, along the longitudinal circular section of the wire-winding cylinder 1, the bottom width W1 is greater than the top width W2. When machining the dovetail shape of the embedding groove 11, a straight groove is first machined, and then both sides are machined with a dovetail cutter. The laser-resistant strip 2 is directly machined into a trapezoid, and then after heating and micro-deformation, it is embedded into the embedding groove 11 to make it fit with the dovetail-shaped embedding groove 11; or according to the cross-sectional area of the dovetail shape of the embedding groove 11, a laser-resistant strip 2 with an approximately same cross-sectional area and similar shape is calculated and machined, and then the laser-resistant strip 2 is installed in the embedding groove 11, and then through extrusion micro-deformation, the laser-resistant strip 2 is made to fit with the dovetail-shaped embedding groove 11.

[0047] Furthermore, as Figure 6 shown in the figure, after the laser-resistant strip 2 is installed in place in the embedding groove 11, the two sides of the laser-resistant strip 2 are not higher than the top of the embedding groove 11; preferably, the two sides of the laser-resistant strip 2 are flush with the arc surface angle of the wire-winding cylinder 1 (that is, the two side vertices of the embedding groove 11). In this way, when the wire-winding cylinder 1 is being wound with wire, the wire can be directly wound on the wire-winding cylinder 1 and smoothly cross over the laser-resistant strip 2 without unevenness, which may cause the wire winding to be blocked.

[0048] After the laser-resistant strip 2 is embedded into the embedding groove 11, it can also be fixed with rivets 3, as Figure 7 、 Figure 8 、 Figure 9 shown in the figure, that is, a first rivet hole 21 is opened on the laser-resistant strip 2, and a second rivet hole 12 is opened at the bottom of the embedding groove 11 of the wire-winding cylinder 1; after the laser-resistant strip 2 is installed in place in the embedding groove 11, the first rivet hole 21 and the second rivet hole 12 are aligned and penetrated, and the rivet 3 is inserted and tightened, then the laser-resistant strip 2 can be further reliably fixed in the embedding groove 11.

[0049] The first rivet hole 21 is preferably a through hole, penetrating the thickness direction of the laser-resistant strip 2.

[0050] The second rivet hole 12 is preferably a blind hole, or can also be a through hole penetrating the wire winding cylinder 1.

[0051] The rivet 3 is preferably a straight nail, and the first rivet hole 21 and the second rivet hole 12 are straight holes. Through the tensioning of the rivet 3, the friction between the straight nail and the straight hole is used for fixation.

[0052] Furthermore, as Figure 9 shown, the rivet 3 is preset as a straight nail. The first rivet hole 21 is a tapered hole that is thicker at the top and thinner at the bottom (hole bottom D1 < hole opening D2), and the second rivet hole 12 is a tapered hole that is thinner at the top and thicker at the bottom (hole opening D1 < hole bottom D3). After the rivet 3 is knocked into the hole, it deforms and fills the hole, forming a spindle shape, thereby more reliably fixing the laser-resistant strip 2 in the embedding groove 11 of the wire winding cylinder 1.

[0053] As a further improvement of the present utility model, at both ends of the spool, that is, on the flange 5, a mark 4 is preferably provided, and the mark 4 is aligned with the laser-resistant strip 2; thus, when performing laser wire cutting operations, by aligning the marks 4 at both ends of the spool, the laser beam can be aligned with the position where the laser-resistant strip 2 is located; furthermore, when performing laser wire cutting operations, the laser beam irradiates on the laser-resistant strip 2, and it will not cause a serious impact on the alignment, thereby enabling the rapid reuse of the spool.

[0054] The mark 4 can be an etched mark or a painted mark.

[0055] The present utility model provides a durable spool capable of laser wire cutting. Embodiment 2, as Figure 10 , Figure 11 , Figure 12 , Figure 13 shown, that is, on the basis of the aforementioned durable spool capable of laser wire cutting, when the flanges 5 at both ends of the spool have a certain thickness, flange embedding grooves 51 can be opened along the diameter direction on the inner sides of the two flanges 5, and flange laser-resistant strips 6 are embedded therein; the cross-sectional structure of the flange embedding grooves 51 can be consistent with that of the embedding grooves 11, and the flange embedding grooves 51 communicate with the embedding grooves 11, so that the flange laser-resistant strips 6 are connected with the laser-resistant strips 2 to form a complete laser-resistant cutting area.

[0056] Furthermore, the open end of the flange embedding groove 51 is located at the edge of the flange 5, so that the flange laser-resistant strip 6 is flush with the circumferential surface of the flange 5, and the top of the flange laser-resistant strip 6 also has the function of the mark 4.

[0057] After the flange laser-resistant strip 6 is embedded in the inner side of the flange 5, the laser cutting angle can be adjusted to perform laser cutting on the wire near the flange 5, ensuring that all the wires on the entire durable spool can be cut off by the laser cutting machine at one time.

[0058] After the spool has been laser wire-cut and reused many times, when the laser beam cutting performance of the laser-resistant strip 2 deteriorates, the spool can be returned to the factory, the laser-resistant strip 2 can be removed, and a new laser-resistant strip 2 can be replaced, and then it can be used again.

[0059] The preferred embodiments of the present utility model have been specifically described above. However, the present utility model is not limited to the described embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present utility model, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
