Description

Technical Field

[0001] This utility model relates to the field of cable production equipment technology, and in particular to a device for preventing the derailment of a guide wheel in a cable production line. Background Technology

[0002] In cable production lines, the guide wheel device is a crucial auxiliary equipment, playing a vital role throughout the entire production process and directly impacting production efficiency and product quality. Through precise mechanical design, the guide wheel device ensures that conductors, cores, or cables move along a predetermined path in the cable production line during stranding, extrusion, cabling, and take-up / unwinding stages, preventing deviation or off-tracking. Especially when conductors, cores, or cables encounter large turning angles, without a properly designed anti-derailment device, the guide wheel may sag due to weight, easily moving outwards and deviating from the guide wheel, potentially causing scratches or even breakage. This not only severely affects product quality but also impacts the production efficiency of the cable production line. Utility Model Content

[0003] The purpose of this invention is to provide a device for preventing the guide wheel of a cable production line from detaching, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] Steering guide wheel shaft;

[0007] The lower cover plate has a central boss and an outer flange with several stepped holes evenly distributed on the flange.

[0008] The upper cover plate has the same structure as the lower cover plate and can be interchanged with the lower cover plate.

[0009] Multiple stop bars, each with a screw hole at both ends, are placed in the corresponding stepped holes in the upper and lower cover plates;

[0010] The internal hexagonal head screws pass through the small holes of the stepped hole and are fastened to the screw holes at both ends of the stop bar, so that the upper cover plate, lower cover plate and stop bar are connected to form a frame;

[0011] The steering guide wheel has a groove on its outer periphery for conductors / cores / cables to pass through, and a large inner hole and a small inner hole inside, with a groove on the wall of the large inner hole;

[0012] A deep groove ball bearing, wherein the outer ring is transitionally fitted with the large inner bore and is axially limited by a boss formed by an elastic retaining ring and a small inner bore within the groove;

[0013] Flat washers and socket head cap screws are used to fasten the assembled frame to the small end of the steering guide wheel shaft via the inner ring of the deep groove ball bearing;

[0014] A gap is left between the stop bar and the groove surface of the steering guide wheel, allowing only the conductor / core / cable to pass through, to prevent the cable from deviating from the groove surface.

[0015] The steering guide wheel has several through holes evenly distributed around its circumference to reduce weight and achieve dynamic balance.

[0016] The width of the groove is greater than the internal width of the steering guide wheel, and the shape of the groove matches the structure of the cable passing through it.

[0017] The surface of the groove is treated with ceramic spraying to improve wear resistance and service life.

[0018] The inner diameter of the flange of the lower cover plate is larger than the outer diameter of the groove of the steering guide wheel, and a gap is maintained between the end face of the boss and the end face of the deep groove ball bearing to ensure that the steering guide wheel rotates flexibly.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] like Figure 1-4 As shown, this utility model provides a cable production line steering guide wheel anti-detachment device, which consists of multiple hexagon socket head cap screws 2, a lower cover plate 3, multiple stop bars 4, an upper cover plate 5, a flat washer 6, hexagon socket head cap screws 7, a steering guide wheel 8, a hole elastic retaining ring 9, and a deep groove ball bearing 10.

[0029] The large inner bore 8.4 of the steering guide wheel 8 and the outer ring of the deep groove ball bearing 10 are fitted with a transition fit. A groove 8.4.1 is machined inside the large inner bore 8.4. A retaining ring 9 is installed on the groove 8.4.1 within the large inner bore 8.4, which axially limits the outer ring of the deep groove ball bearing 10 installed within the large inner bore 8.4. The steering guide wheel 8 also has a small inner bore 8.1 machined inside. The boss formed by the small inner bore 8.1 and the large inner bore 8.4 axially limits the outer ring of the deep groove ball bearing 10 installed within the large inner bore 8.4. The guide wheel 8 has multiple through holes 8.2 of the same size machined evenly in the circumferential direction. Machining multiple through holes 8.2 of the same size can effectively reduce the weight of the steering guide wheel 8 and facilitate smooth movement when the steering guide wheel 8 rotates. The outer end of the steering guide wheel 8 is machined with a groove surface 8.3. The width of the groove surface 8.3 is slightly wider than the inner width of the steering guide wheel 8. The shape of the groove surface 8.3 needs to be changed according to the structural characteristics of the conductor, wire core or cable passing through it. The two end faces of the deep groove ball bearing 10 installed into the large inner hole 8.4 are respectively spaced at the same distance from the two end faces of the inner end face of the steering guide wheel 8.

[0030] A boss 3.2 is machined at the center of the lower cover plate 3. The distance between the boss 3.2 and the upper end face of the lower cover plate 3 is slightly wider than the distance between the end face of the deep groove ball bearing 10 installed in the large inner hole 8.4 and the inner end face of the steering guide wheel 8. A through hole 3.2.1 is machined inside the boss 3.2, which is clearance-fitted with the outer diameter of the small end of the steering guide wheel shaft 1. A flange 3.1 is machined on the outer end of the lower cover plate 3. A plurality of stepped holes 3.1.1 are uniformly machined in the circumferential direction of the flange 3.1. The large and small holes of the stepped holes 3.1.1 are clearance-fitted with the outer diameters of the stop bar 4 and the internal hexagonal head screw 2, respectively. The inner diameter of the flange 3.1 machined on the outer end of the lower cover plate 3 needs to be slightly larger than the outer diameter of the groove surface 8.3 of the steering guide wheel 8.

[0031] The upper cover plate 5 and the lower cover plate 3 are exactly the same size, and can be used in reverse. Multiple identical stop bars 4 are installed in the large holes of stepped holes 5.1.1 and 3.1.1. Each stop bar 4 has threaded holes at both ends, which are threaded to hexagonal head screws 2. By tightening the hexagonal head screws 2 threaded to both ends of the stop bar 4, each stop bar 4 can be secured between the upper cover plate 5 and the lower cover plate 3. The distance between the flanges 3.1 and 5.1 between the stop bars 4 and the flanges 3.1 between the upper cover plate 5 and the lower cover plate 3 should be the same as the distance between the flanges 3.1 and 5.1 between the steering guide wheel 8 installed on the upper cover plate 5 and the lower cover plate 3.

[0032] The small end of the steering guide wheel shaft 1 is fitted with the inner ring of the deep groove ball bearing 10 using an transition fit. The length of the small end of the steering guide wheel shaft 1 needs to be slightly shorter than the total thickness of the lower cover plate 3, the steering guide wheel 8, and the upper cover plate 5 assembly. The head of the small end of the steering guide wheel shaft 1 is machined with a screw hole, which is threaded to a hexagon socket head cap screw 7. By tightening the hexagon socket head cap screw 7, which passes through the inner hole of the flat washer 6 and is threaded to the head of the small end of the steering guide wheel shaft 1, the steering guide wheel anti-disengagement device can be fastened to the head end face of the small end of the steering guide wheel shaft 1.

[0033] The dimensional requirements between the components of the aforementioned steering guide wheel anti-derailment device can effectively prevent conductors, wires, or cables passing through the steering guide wheel anti-derailment device from deviating from the steering guide wheel; the conductors, wires, or cables must be passed between the groove surface 8.3 of the steering guide wheel 8 and the stop bar 4 in order for the steering guide wheel anti-derailment device to be used.

[0034] As a further improvement of this utility model, if the groove surface 8.3 of the steering guide wheel 8 is treated with ceramic spraying, the service life of the steering guide wheel 8 and the reliability of the steering guide wheel anti-detachment device will be effectively improved.

[0035] The working principle of this utility model is as follows:

[0036] 1) Based on the structural characteristics of the conductors, cores or cables that the cable production line needs to pass through and the installation position dimensions of the steering guide wheel shaft 1, and in conjunction with the above technical solutions, design a drawing of a cable production line steering guide wheel anti-detachment device.

[0037] 2) Based on the design drawings of a cable production line steering guide wheel anti-detachment device, and considering the number of steering guide wheel anti-detachment devices required for the cable production line, process each lower cover plate 3, each upper cover plate 5, each steering guide wheel 8 and each stop bar 4 that meet the actual requirements, and prepare the required hexagon socket head cap screws 2, flat washers 6, hexagon socket head cap screws 7, elastic retaining rings for holes 9 and deep groove ball bearings 10.

[0038] 3) Next, according to the drawing requirements of a cable production line guide wheel anti-detachment device, assemble multiple sets of a cable production line guide wheel anti-detachment device in sequence according to the drawing requirements.

[0039] 4) With the machine stopped, remove each old component from each steering guide wheel shaft 1 in sequence, and then tighten each hexagon socket head cap screw 7 that passes through the flat washer 6 to secure multiple sets of anti-detachment devices for the steering guide wheels of a cable production line to each steering guide wheel shaft 1 in sequence.

[0040] 5) At this point, the installation of a cable production line guide wheel anti-detachment device is completed. After all the preparations for starting the machine are completed, the machine can be started normally.
