Abstract
Description
TECHNICAL FIELD
[0001] The present application belongs to the field of missile launching device, and particularly relates to a forming tool for a launching barrel and a forming method of the launching barrel. BACKGROUND
[0002] Composite material launching barrels are widely used due to their excellent performance of light weight and high strength. There are two main forming methods for the composite material launching barrel with guide rails: the first method is to form the guide rail and the barrel body respectively, and then to install the guide rail on the inner wall of the barrel body by mechanical connection; the second method is to integrally form the guide rail and the barrel body. For a launching barrel with a very long length and a small diameter, the installation and positioning of the guide rail are very difficult when the first method is used, and the production efficiency is low. In addition, screw holes need to be opened on the composite material barrel, which will reduce the strength and sealing performance of the barrel. In comparison, the method of integrally forming the guide rail and the barrel body does not need to open holes on the barrel, does not affect the performance of the barrel, and can reduce the weight of the barrel due to the absence of bolt connection, and can reduce the processing procedures and the operation difficulty, and is a high-efficiency forming method.
[0003] Although the integrally forming method of the composite material launching barrel has obvious advantages, there are still some problems in the forming process, such as the initial fixation of the guide rail and the core mold when the barrel is wound. The common solution to this problem is to manually lay up a layer on the first guide rail, fix the guide rail on the core mold by curing the layer (or paste the pre-impregnated material guide rail on the core mold), and then fix each guide rail in turn. After all the guide rails are fixed, the core mold is wound on the machine to form the barrel. In this method, the curing (or pre-impregnated material pasting) of each guide rail needs to be carried out in turn, and cannot be completed at the same time. The curing of each guide rail takes several hours, and the total curing time of this process is equal to the number of guide rails multiplied by the curing time. Therefore, this manual lay-up (or pre-impregnated material pasting) solution is not only complicated, but also low in forming efficiency of the barrel. Moreover, due to the characteristics of the manual lay-up process, it is difficult to ensure the process quality, and manual lay-up of the guide rail may also need to extend the layer to the outer surface of the core mold to ensure that the cured guide rail does not fall off the core mold. This operation will result in defects or joints (joints between adjacent extended layers) on the wall surface of the formed barrel. The pre-impregnated material pasting process also has quality problems, such as porosity.
[0004] Therefore, it is necessary to provide an efficient forming tool and forming method for the initial fixation of the guide rail and the core mold when the barrel is wound and the forming quality of the launching barrel. SUMMARY
[0005] The technical problems to be solved by the present application are to overcome the deficiencies and defects mentioned in the above background art, and to provide a molding tool for integrally molding and fixing a launch tube with guide rails, which has high molding efficiency and good quality of the launch tube, and a molding method for molding the launch tube with guide rails by using the molding tool.

[0007] In the present application, the installation and adjustment of the guide rail are facilitated by providing the guide rail installation groove. If the guide rail installation groove is not provided, when the molding tool is sleeved on the outer surface of the cylindrical winding core mold, the molding tool closely fits the outer surface of the cylindrical winding core mold, and since the size of the guide rail matches the size of the groove on the outer surface of the cylindrical winding core mold, and there may be a manufacturing tolerance of the guide rail, it may be difficult to directly install the guide rail, and the guide rail cannot be adjusted. By providing the guide rail installation groove, a larger space is left for the installation of the guide rail, which facilitates the installation and position adjustment of the guide rail. Then, by using the locking structure, the guide rail can be fixed. The locking structure of the present application tightly presses the guide rail, has strong pressing force on the guide rail, can adjust the position of the guide rail, and more stably fixes the guide rail, so that the position adjustment of the guide rail is more convenient.

[0057] S2: The guide rails 4 are prepared.
[0058] S3: The plurality of forming tools are evenly segmented and sleeved on the surface of the columnar winding core mold 3, and the first semicircular structure 1 and the second semicircular structure 2 are fixedly connected to each other to close, so that the locking structure is in an unlocked state.
[0059] S4: The guide rails 4 are inserted from the end of the columnar winding core mold 3, and the locking mechanism is adjusted to fix the guide rails 4 in the groove 31 on the outer surface of the columnar winding core mold 3, that is, the fixation of the guide rails 4 and the columnar winding core mold 3 is realized.
[0060] S5: The columnar winding core mold 3 is loaded onto a winding device, and then resin-soaked fiber yarns are wound, cured, and demolded, that is, the forming of the launching cylinder with guide rails is completed.
[0061] In the embodiment, the winding starts from the end surface of the columnar winding core mold 3, when the winding approaches the forming tool, the forming tool is removed and the winding continues backward until the winding on the surface of the columnar winding core mold 3 is completed.
[0062] In this embodiment, the guide rail 4 is prepared by pultrusion process, and the main material of the guide rail 4 is fiber reinforced resin-based composite material; the main material of the launch tube is fiber reinforced resin-based composite material.
[0063] In order to better understand the forming tool and the forming method in this embodiment, a typical forming method is also provided in this embodiment, which includes the following steps:
[0064] First step: according to the internal structure of the launch tube, a cylindrical winding core mold 3 with grooves 31 on the surface is made, the shape of the cylindrical winding core mold 3 matches the shape of the inner cavity of the launch tube with guide rails (as shown in Figure 1 The grooves are uniformly distributed on the circumference.
[0065] Second step: the guide rail 4 is prepared by pultrusion process, a typical guide rail 4 is made of fiber reinforced epoxy resin composite material, and the size of the guide rail 4 is determined according to the size of the groove 31 (as shown in Figure 2 ).
[0066] Third step: the release agent is applied on the surface of the cylindrical winding core mold 3.
[0067] Fourth step: the guide rail 4 is installed into the groove 31 of the cylindrical winding core mold 3, and the assembly relationship between the guide rail 4 and the cylindrical winding core mold 3 is as shown in Figure 3 .
[0068] Fifth step: the forming tool is prepared. According to the positioning relationship between the guide rail 4 and the cylindrical winding core mold 3, a forming tool is designed and made for positioning and clamping the guide rail 4 on the cylindrical winding core mold 3. As shown in Figures 4-6 , the forming tool is composed of two semicircular structures, one side of the two semicircular structures is hinged, and the other side is connected by a buckle, and the loosening and locking of the forming tool are realized by opening and closing the buckle. When the buckle is locked, a complete circular structure is formed, which is in close contact with the circular surface of the cylindrical winding core mold 3. The buckle structure includes a first pin 9, a second pin 10, a buckle 11 and a shaft 12 (which can be an internal hexagonal bolt). One end of the shaft 12 is movably arranged on the first semicircular structure 1 through the first pin 9, and the other end of the shaft 12 is movably arranged on the buckle 11 through the second pin 10. The buckle 11 is movably arranged on the second semicircular structure 2. The first pin 9 is connected with the internal hexagonal bolt, and the second pin 10 is connected with the buckle 11. When the buckle 11 is turned upward, the second pin 10 pushes the internal hexagonal bolt upward, the mechanism is loosened, and the unlocking state is reached. At this time, the forming tool can be removed from the cylindrical winding core mold 3; when the buckle 11 is turned downward, the second pin 10 presses the internal hexagonal bolt downward, and the mechanism is locked. As shown in Figure 7As shown, the forming tool is also provided with a locking mechanism for fixing the guide rail, which is composed of a fixing bolt 6, a plastic sleeve and a pin 7. The plastic sleeve is installed at the bottom of the fixing bolt 6 and connected by the pin 7. The plastic sleeve serves to protect the contact surface of the guide rail 4 from damage. In use, the forming tool is installed on the cylindrical winding core mold 3, and the locking mechanism is aligned with the guide rail 4. The fixing bolt 6 is tightened to fix the guide rail 4.
[0069] Step 6: Fix the guide rail 4 to the cylindrical winding core mold 3 using 3 forming tools. As shown in Figures 8-10 , the guide rail 4 is installed into the groove 31 of the cylindrical winding core mold 3, as shown in Figures 11-12 , the assembled guide rail 4 and the cylindrical winding core mold 3 are locked by the locking mechanism of the forming tool, and the fixing bolt 6 is used to fix the guide rail 4. The specific operation can be as follows: the forming tool is installed on the cylindrical winding core mold 3 according to the relative position relationship between the locking mechanism and the groove 31, and is turned down to buckle and lock the forming tool. The fixing bolt 6 is pushed to the non-locking position. Each time, one guide rail 4 is inserted into the groove from the side. Finally, the fixing bolt 6 is locked until all the guide rails 4 are installed and fixed.
[0070] Step 7: Load the cylindrical winding core mold 3 onto the winding equipment. According to the structural design requirements, the fiber yarn soaked with resin is used to wrap the launch cylinder body (as shown in Figure 13 ), and the winding machine drives the overall mechanism of the cylindrical winding core mold 3 to rotate at an angular velocity ω. When the fiber yarn is about to complete the winding to cover the area A, the forming tool between the area A and the area B is removed, and the winding continues. When the winding is about to complete the coverage of the area B, the forming tool between the area B and the area C is removed, and the winding continues. When the winding is about to complete the coverage of the area C, the last forming tool is removed, and the winding is finally completed.
[0071] Step 8: Curing and demolding, i.e. completing the integrated molding of the launch cylinder with guide rails.
[0072] After comparison, the forming method in the embodiment has the following specific effect compared with the traditional hand lay-up process, as shown in Table 1.
