Description

Technical Field

[0001] The utility model relates to the technical field of fiber material processing, in particular to an anti-collapse measurable baffle used for winding molding of thick-walled annular parts. Background Art

[0002] The winding molding process is one of the main manufacturing processes of resin-based composite materials. It is a method in which continuous fiber roving or cloth tape is impregnated with resin glue under controlled tension and predetermined linear conditions, continuously wound on a core mold or lining corresponding to the inner cavity size of the product, and then cured at room temperature or heating conditions to form a product of a certain shape.

[0003] When using the existing winding molding process to produce thick-walled annular fiber winding molded products, the winding is generally carried out directly on the mold; this will cause the two ends of the thick-walled annular fiber winding molded products to collapse, affecting the dimensional stability of the products; when the winding fiber bundle is wound to the two ends of the winding formation, because there is no obstruction on both sides of the winding product, and under the action of the tension of the winding fiber, as the thickness of the winding product increases, the winding fiber will collapse at both ends of the product, causing the product to increase in length and decrease in thickness; therefore, in order to meet the size of the target product, cutting sections must be reserved at both ends of the product during winding production, and the reserved parts must be cut off after curing and molding, retaining the middle product part; this causes waste of raw materials and increases production costs. Utility Model Content

[0004] The purpose of the utility model is to provide a measurable anti-collapse baffle for winding molding of thick-walled annular parts, so as to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A measurable anti-collapse baffle for winding molding of thick-walled annular parts, comprising a group of measuring baffle assemblies installed at the upper and lower ends of the outer side of the winding mold, wherein the measuring baffle assembly comprises a pair of matching arc-shaped baffles, and a flange plate is provided at the intersection of the upper ends of the pair of baffles, and a protective layer is pasted on the inner side of each of the flange plates. A number of fastening bolts are provided through the intersection of the two flange plates, and a dimension mark is provided on the lower surface of each baffle.

[0007] As a further solution of the present invention: a pair of baffles are spliced into a circular structure, and the center of the circular structure is a hollow structure, and the diameter of the hollow structure is equal to the outer diameter of the winding mold.

[0008] As a further solution of the present invention: a winding nozzle is provided on one side of the winding die, and nozzle mounting frames are installed on the upper and lower ends of the winding nozzle.

[0009] As a further solution of the present invention: the protective layer is a component made of tetrafluoroethylene.

[0010] As a further solution of the present invention: the baffle is a component made of metal material, and the size marking line is etched on the lower surface of the baffle by ferric chloride etching solution.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The utility model firmly fixes a pair of baffles on the winding mold by fastening bolts, and can form the fiber bundle wound on the winding mold into a thick-walled annular part that is resistant to collapse, thereby effectively reducing the collapse of the two ends of the thick-walled annular part during the winding process, thereby reducing the waste of raw materials and reducing production costs; by reading the value of the contact position between the fiber bundle wound on the winding mold and the size mark, a thick-walled annular part of the required thickness can be obtained; the protective layer can effectively avoid damage to the surface of the winding mold during disassembly and tightening, thereby increasing the service life of the winding mold.

[0018] See also Figures 1 to 4The cam 75 is provided with a plurality of screw threads 76 on the top of the cam 76, and the screw thread 76 is provided with a plurality of screw threads 77 on the bottom of the cam 76.

[0019] like Figure 1 and Figure 2 As shown, a pair of baffles 71 are spliced into a circular structure, and the center of the circular structure is a hollow structure. The diameter of the hollow structure is equal to the outer diameter of the winding mold 3, so that the measuring baffle assembly 7 can be fixedly installed on the winding mold 3.

[0020] Preferably, a winding nozzle 2 is provided on one side of the winding mold 3, and nozzle mounting frames 21 are installed at the upper and lower ends of the winding nozzle 2. The fiber bundle 1 after spinning, dipping and tension control reaches the winding nozzle 2, and is continuously wound on the winding mold 3 after passing through the winding nozzle 2. The winding nozzle 2 is supported by the nozzle mounting frame 21 so that the winding nozzle 2 can rotate smoothly.

[0021] Preferably, the protective layer 73 is a component made of tetrafluoroethylene. When the measuring baffle assembly 7 is fastened to the winding mold 3, it directly contacts the winding mold 3 through the protective layer 73, which can effectively avoid damage to the surface of the winding mold 3 during the disassembly and fastening process.

[0022] Preferably, the baffle 71 is a component made of metal material, and the size marking line 75 is etched on the lower surface of the baffle 71 by ferric chloride etching solution, so that it is not easily worn during use.

[0023] Working principle of existing technology: In the existing technology, such as Figure 3 As shown, the fiber bundle 1 to be wound is spun, dipped in glue, and tension-controlled before arriving at the winding nozzle 2. After passing through the winding nozzle 2, it is continuously wound on the winding die 3. As the winding progresses, a thick-walled annular initial product 4 is formed, and uneven product sections 41 are formed at the upper and lower sections of the thick-walled annular initial product 4. After the thick-walled annular initial product 4 is heated and cured, the uneven product sections 41 at the upper and lower ends are cut to form a thick-walled annular product 5, and useless product waste sections 6 are generated.

[0024] Working principle of the present invention: In the present invention, Figure 4 As shown, according to the length of the thick-walled hoop-wound product, two measuring baffle assemblies 7 are respectively installed at the two ends of the winding mold 3; the fiber bundle 1 to be wound is spun, impregnated, and tension-controlled before arriving at the winding nozzle 2, and is continuously wound on the winding mold 3 after passing through the winding nozzle 2, and the value on the size mark 75 is read. When the thickness of the thick-walled hoop-wound product reaches the specified thickness, it is heated, cured, and demolded to form a thick-walled annular product 8 that prevents collapse, which can effectively reduce the collapse of the two ends of the wound product during the winding process.

[0025] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
