Description

Technical Field

[0004] The invention belongs to the field of wire guide devices, and in particular relates to a fiber band-shaped bundle winding wire guide device and method. Background Art

[0005] At present, the winding industry has been widely used in national defense and civilian technology, such as the production of rocket engine casings, missile launch tubes, pressure vessels, municipal pipelines, etc. These products have the advantages of light weight, high strength, no rust, corrosion resistance, low thermal expansion coefficient, and long service life. Most of them use CNC winding machines to wind multiple strands of fibers in the shape of cloth strips or round rods on the core film through the drive of its main shaft and winding nozzle. When winding, the fibers must be flat and evenly and continuously covered on the surface of the core mold according to a certain rule. First, the relative motion relationship between the core mold and the winding head must be found, and the winding rule must be set. It is also necessary to configure an advanced and reasonable fiber bundle guide head. The fiber bundle guide head of the prior art generally adopts the upper and lower inner arc surfaces of two circular rings (circular tubes) or the upper and lower outer arc surfaces of two rollers. This structural design allows the fiber bundle to first transition through the lower limit guide head with the arc center facing the upper arc, and then to the upper limit guide head with the arc center facing the lower arc to gather and tighten. After passing through the two wire guides, the fiber bundle changes according to the shape of the wire surface, making the fiber bundle uneven, the tightness of each fiber strand different, and the tension size different, which seriously affects the quality of the wound product.

[0006] In order to ensure high-precision winding quality, it is crucial to make innovative designs on the wire guide device to bundle multiple strands of fibers into the shape required for winding, make the pay-off smooth and flat, and ensure that the tension of each strand of yarn is consistent. Summary of the invention

[0007] The purpose of the present invention is to provide a fiber band-shaped bundle winding guide wire device to solve the problem of kinks and uneven tightness when winding multiple strands of fibers in a band-shaped bundle, resulting in poor quality of the wound product. The device can evenly and continuously cover the core mold according to the set rules, and the pay-off is smooth and flat, and the tension of each strand of fiber is basically the same.

[0008] In order to solve the above problems, the present invention discloses a fiber band-shaped bundle winding guide wire device, comprising an upper limit guide wire head, a lower limit guide wire head and a comb-shaped guide wire head arranged in sequence; the upper limit guide wire head comprises a first arc bent rod, a first connecting plate and a first support rod, the first arc bent rod is arranged at the upper part of the first connecting plate, and the first support rod is arranged at the lower part of the first connecting plate; the lower limit guide wire head comprises a second arc bent rod, a second connecting plate and a second support rod, the second arc bent rod is arranged at the upper part of the second connecting plate, and the second support rod is arranged at the lower part of the second connecting plate; the radius of the first arc bent rod is smaller than the radius of the second arc bent rod, and the vertex of the second arc bent rod is lower than the vertex of the first arc bent rod.

[0009] As a further improvement of the above technical solution:

[0010] The comb-shaped wire guide head comprises a comb finger rod, a comb seat and a third support rod, the comb finger rods are evenly distributed on the comb seat, and the third support rod is arranged below the comb seat.

[0011] The inner surface of the arc of the first arc bent rod is a smooth structure, the outer surface of the arc of the second arc bent rod is a smooth structure, and the comb finger rod is a cylindrical structure with a smooth surface.

[0012] It also includes a support, and the upper limit wire guide head, the lower limit wire guide head and the comb-shaped wire guide head are installed on the support. The support includes a support rod, a rib plate and a fixed plate. The support rod is connected to the fixed plate. The rib plate is arranged on one side of the support rod and is connected to the fixed plate to strengthen the connection strength between the support rod and the fixed plate.

[0013] The support rod is provided with a plurality of through holes for installing the first support rod, the second support rod and the third support rod. The through holes are provided with locking holes perpendicular thereto, and the locking holes are provided with set screws.

[0014] The present invention also discloses a fiber band-shaped bundle winding guide wire method, comprising the following steps:

[0015] S1, passing each strand of fiber from the winding machine through the winding nozzle through the comb-shaped wire guide head, the lower limit wire guide head and the upper limit wire guide head respectively, and then fixing the wire end on the winding machine main shaft core mold;

[0016] S2. Set the fiber bundle tension, adjust the position of the winding machine's winding head and the height of the comb-shaped wire guide head, the lower limit wire guide head and the upper limit wire guide head, so that the fibers are in a tightened state, and each fiber is symmetrically laid side by side with equal distances between adjacent comb fingers of the comb-shaped wire guide head, tangent to the outer side of the comb finger rod, supported by the outer arc surface of the second circular bend rod of the lower limit wire guide head, gradually gathered, transitioned to the upper limit wire guide head, and bundled and tightened into a belt shape through the inner arc surface of the first circular bend rod of the upper limit wire guide head.

[0017] According to the requirements of product structure for strength and rigidity, the corresponding winding equipment and winding process are selected. Through the relative motion relationship between the core mold and the winding head, the fiber bundle is evenly and continuously spread on the surface of the core mold according to a certain rule until the core mold winding is completed.

[0019] The fiber band-shaped bundle winding guide wire device of the present invention has a novel and ingenious design, a simple structure and a low manufacturing cost. The disassembly, assembly, debugging, maintenance and cleaning operations are convenient and quick. The combined use of multiple guide wire heads can not only ensure that each strand of fiber is evenly arranged at an equal distance to prevent kinking, but also can quickly bundle and gather them. Moreover, the cross-sectional shape changes little after passing through each guide wire head, the wire laying is smooth and flat, the fiber wear is small, and the tension changes little, which greatly improves the winding quality. Especially for wet winding, the arc of the wire guide head passing through the wire face faces downward, and excess glue is not easy to accumulate on the wire guide head, which reduces the number of times the wire guide head is cleaned and improves work efficiency. The combined design of the wire guide heads forms a closed crescent shape in the fiber bundle running area, so that the fiber bundle is not easy to run away or drop the yarn during the winding process, and it is safe and reliable to use.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 3 As shown, the fiber band-shaped bundle winding guide wire device of this embodiment includes an upper limit guide wire head 1, a lower limit guide wire head 2 and a comb-shaped guide wire head 3 arranged in sequence; it also includes a support 5, and the upper limit guide wire head 1, the lower limit guide wire head 2 and the comb-shaped guide wire head 3 are installed on the support 5.

[0035] like Figures 7 to 9As shown, the support 5 includes a support rod 15, a rib plate 16 and a fixed plate 17. The support rod 15 is connected to the fixed plate 17. The rib plate 16 is arranged on one side of the support rod 15 and is connected to the fixed plate 17 to strengthen the connection strength between the support rod 15 and the fixed plate 17. The support rod 15 is similar to a stepped shaft, and the large shaft section is symmetrically milled with two planes up and down. Three vertical circular through holes are drilled in sequence at the far end of the cantilever, and a threaded hole is processed in the center of one side of the vertical circular through hole, and the set screw 4 is screwed thereto. The small shaft section is inserted into the middle circular through hole of the fixed plate 17, so that the two planes of the large shaft are parallel to the axis of the upper and lower two sets of mounting holes of the fixed plate 17, and the head is slightly lower than the outer surface of the fixed plate 17. The fixed plate 17 is processed with 4 circular through holes for device installation.

[0036] The support rod 15 is provided with a plurality of through holes for installing the first support rod 8, the second support rod 11 and the third support rod 14. The through holes are provided with locking holes perpendicular thereto, and the locking holes are provided with set screws 4. The support rods of the upper limit wire guide head 1, the lower limit wire guide head 2 and the comb-shaped wire guide head 3 are inserted into the through holes of the support 5 in sequence, and the upper and lower movable ranges of the yarn are adjusted by fine-tuning the height of the support rods. Each wire guide head with adjusted height is screwed into the locking hole on the side of the support 5 with the set screws 4 to tighten the support rods. Then, the device is installed on the winding head of the winding machine through the four round holes on the support 5 with screws, and the device is fed and rotated together with the winding head. Among them, the comb-shaped wire guide head 3 is in the shape of a comb, and the spacing between the comb fingers is equal. The upper limit wire guide head 1 and the lower limit wire guide head 2 both use arcs with the arc center facing downward, the arc radius of the upper limit wire guide head 1 is smaller, and the arc radius of the lower limit wire guide head 2 is larger. Each fiber coming from the winding nozzle first passes through the comb-shaped wire guide head 3 and is flattened between its adjacent comb fingers, so that the left and right movement of the yarn is restricted and the spacing is equal. Then it goes to the lower limit wire guide head 2, and each fiber clings to its outer arc surface to slightly close the left and right spacing, and restricts its downward movement, which plays a transitional role in the gathering of the upper limit wire guide head 1. Then it goes to the upper limit wire guide head 1, and each fiber clings to its inner arc surface to gather and tighten, and restricts its upward movement. Under the joint action of the three wire guide heads, each strand of fiber naturally and smoothly gathers and gradually pays out in a belt-like shape.

[0037] like Figure 4 As shown, the upper limit wire guide head 1 includes a first arc bent rod 6, a first connecting plate 7 and a first support rod 8, all of which are made of stainless steel. The first arc bent rod 6 is arranged on the upper part of the first connecting plate 7, and the first support rod 8 is arranged on the lower part of the first connecting plate 7. The first arc bent rod 6 is bent by round steel, and the arc radius is relatively small. The two ends of the first arc bent rod 6 are milled flat and symmetrically welded to the two ends of the first connecting plate 7. The first support rod 8 is a stepped shaft, and the small shaft section is inserted into the hole at the center of the first connecting plate 7, and its head is slightly lower than the upper surface of the first connecting plate 7. Then the shoulder of the first support rod 8 and the connection with the lower surface of the first connecting plate 7 are welded firmly. The inner surface of the arc of the first arc bent rod 6 is very smooth to reduce the wear on the yarn.

[0038] like Figure 5As shown, the lower limit wire guide head 2 includes a second arc bent rod 9, a second connecting plate 10 and a second support rod 11, all of which are made of stainless steel. The second arc bent rod 9 is arranged on the upper part of the second connecting plate 10, and the second support rod 11 is arranged on the lower part of the second connecting plate 10; the radius of the first arc bent rod 6 is smaller than the radius of the second arc bent rod 9, and the vertex of the second arc bent rod 9 is lower than the vertex of the first arc bent rod 6. The second arc bent rod 9 is bent by round steel, and the arc radius is relatively large. The two ends of the second arc bent rod 9 are milled flat and symmetrically welded to the lower step surfaces at both ends of the second connecting plate 10. The second support rod 11 is a stepped shaft, and the small shaft section is inserted into the hole at the center of the second connecting plate 10, and its head is slightly lower than the upper surface of the second connecting plate 10. Then the connection between the shoulder of the second support rod 11 and the lower surface of the second connecting plate 10 is welded firmly. The arc outer surface of the second arc bent rod 9 is very smooth to reduce wear on the yarn.

[0039] like Figure 6 As shown, the comb-shaped wire guide head 3 includes a comb finger rod 12, a comb seat 13 and a third support rod 14, all of which are made of stainless steel. The comb finger rods 12 are evenly distributed on the comb seat 13, and the third support rod 14 is arranged below the comb seat 13. The comb finger rod 12 is a small round rod with a very smooth surface and the same length and size, which plays the role of a wire guide. After the bottom is coated with glue, it is inserted into the equidistant blind hole at the upper end of the comb seat 13 and fastened. The third support rod 14 and the comb seat 13 are round steel with the same diameter. The third support rod 14 is vertically centered and welded to the lower end of the comb seat 13 in a T shape.

[0040] The fiber band-shaped bundle winding guidewire method of this embodiment comprises the following steps:

[0041] S1, passing each strand of fiber from the winding machine through the winding nozzle through the comb-shaped wire guide head 3, the lower limit wire guide head 2 and the upper limit wire guide head 1 respectively, and then fixing the wire end on the winding machine main shaft core mold;

[0042] S2. Set the fiber bundle tension, adjust the position of the winding machine's winding head and the height of the comb-shaped wire guide head 3, the lower limit wire guide head 2 and the upper limit wire guide head 1, so that the fibers are in a tightened state, and each fiber is symmetrically laid side by side between adjacent comb fingers of the comb-shaped wire guide head 3 at equal distances, tangent to the outer side of the comb finger rod 12, and is gradually gathered and transitioned to the upper limit wire guide head 1 by the outer arc surface of the second arc bent rod 9 of the lower limit wire guide head 2, and is bundled and tightened into a belt shape by the inner arc surface of the first arc bent rod 6 of the upper limit wire guide head 1.

[0043] The present invention can ensure that each strand of fiber is evenly arranged at an equal distance and prevent kinking through the combined use of multiple wire guides, and can also quickly bunch and gather them. After passing through each wire guide, the cross-sectional shape changes little, the wire laying is smooth and flat, the fiber wear is small, and the tension changes little, which greatly improves the winding quality. Especially for wet winding, the wire guide has a downward arc passing surface, and excess glue is not easy to accumulate on the wire guide, which reduces the number of wire guide cleaning times and improves work efficiency. The combined design of the wire guides forms a closed crescent shape in the fiber bundle running area, so that the fiber bundle is not easy to run off during the winding process, and it is safe and reliable to use.

[0044] The above is only an embodiment of the present invention, and the common sense such as the known specific structure and characteristics in the scheme is not described in detail here. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the attached claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims.
