Description

Technical Field

[0001] The invention belongs to the field of composite material helmet manufacturing, and in particular relates to a composite material helmet winding molding device and a molding method. Background Art

[0002] There are two main types of existing bulletproof helmet molding methods. One is the layer-by-layer molding method: it is mainly made of aramid fiber prepreg or ultra-high molecular weight polyethylene fiber prepreg, which is cut and laid on a mold and then subjected to multiple processes such as cold press pre-pressing, sawing edge trimming, and hot press heating and pressurization. In addition, in order to meet the needs of the helmet shape, multiple layers of prepreg need to be cut when they are laid and stacked to ensure the flatness and conformality of the prepreg. Therefore, the cut position becomes the weak point of the helmet's bulletproofing.

[0003] The other type is the winding molding method. For example, patent CN2017105490320 provides a preparation device for an ultra-high molecular weight polyethylene fiber bulletproof helmet. The device includes a spinning mechanism and a mold mechanism. Through the combination of spinning technology and winding technology, continuous fiber winding molding ensures the integrity of the fibers in the helmet shell, thereby solving the problem that the fiber ends generated by the stacking laying molding affect the bulletproof performance of the helmet. The mold mechanism in the invention device needs to be provided with at least two male molds on the inner disk of the base, and the inner disk needs to rotate to drive the two male molds to alternately replace. The inner disk needs to be equipped with a rotating power mechanism for its rotation, and the two male molds also need to control their own rotation The rotating power mechanism is also required to separately control its own rotation.

[0043] The flipping and telescopic execution unit 3 controls the flipping plate 2 to flip around the hinge axis by telescoping; specifically, the flipping plate 2 is configured to connect two sets of flipping and telescopic execution units 3 so that the power is balanced and the flipping is smooth, and one end of each set of flipping and telescopic execution units 3 is hinged to the workbench 1, and the other end is hinged to one side of the flipping plate 2. Preferably, the flipping and telescopic execution unit 3 uses a telescopic cylinder or an electric push rod, the cylinder body of the telescopic cylinder or the electric push rod is hinged to the workbench 1, and the telescopic rod of the telescopic cylinder or the electric push rod is hinged to the flipping plate 2.

[0045] Since the rotating support shaft 42 is perpendicular to the upper surface of the flip plate 2, when the flip plate 2 is flipped to an upright state (the upper surface of the flip plate 2 is perpendicular to the horizontal table 11), the male mold 4 as a whole moves from below the female mold 7 to the outside between the female mold 7 and the table 11. There is ample space, and the rotating axis of the male mold 4 is horizontally placed, which is more convenient for cooperating with the silk-spinning mechanism to carry out the winding process.

[0053] A pressing execution unit 8 is also fixed above the workbench 1, and the telescopic rod of the pressing execution unit 8 is fixedly connected to the female mold 7. The female mold 7 can rise and press down in the vertical direction driven by the telescopic rod of the pressing execution unit 8; it can close the mold with the male mold 4 when pressing down.

[0054] Preferably, in order to better accurately align the female mold 7 with the male mold 4 , a positioning column 71 is fixedly provided on the female mold 7 , and a positioning hole 52 matching the positioning column 71 is opened on the support block 5 .

[0055] Furthermore, the pressing execution unit 8 adopts a hydraulic cylinder, a pneumatic cylinder or an electric push rod, the cylinder body of the hydraulic cylinder, the pneumatic cylinder or the electric push rod is fixed above the workbench 1 through a fixing frame, and the telescopic rod of the hydraulic cylinder, the pneumatic cylinder or the electric push rod is fixedly connected to the female mold 7.

[0056] The molding method using the molding device of the present invention comprises:

[0057] S1, control the telescopic rod of the flip telescopic execution unit 3 to extend, drive the flip plate 2 to flip around the hinge axis with the workbench 1 to an upright state, so that the male mold 4 connected to the flip plate 2 moves outward from directly below the female mold 7, and the rotation axis of the male mold 4 is horizontally placed, and the male mold 4 rotates under the drive of the motor, and cooperates with the movement of the spinning mechanism to lay the fiber prepreg yarn on the male mold at a winding angle of 45° / -45° to form a composite helmet embryo;

[0059] S3, controlling the telescopic rod of the translation and telescopic execution unit 6 to extend, pushing the support block 5 to slide between the flip plate 2 and the male mold 4, and the upper surface of the support block 5 abuts against the supporting male mold 4;

[0060] S4, control the telescopic rod of the downward pressing execution unit 8 to extend downward, drive the female mold 7 to be pressed downward, and guide the positioning through the corresponding positioning holes 52 on the positioning column and the support block 5, so as to realize the closing of the female mold 7 with the male mold 4 below and press the composite helmet embryo between the two; the pressing molding is the hot pressing molding of the prior art, that is, the downward pressing execution unit continuously provides a certain pressure, and the mold mechanism continuously provides a certain heating temperature through the attached heating unit.

[0061] S5. After the hot pressing forming is completed, the telescopic rod of the downward pressing execution unit 8 is controlled to retract upward, driving the female mold 7 to be lifted and separated from the male mold 4, exposing the formed composite helmet shell and separating it from the male mold.

[0062] Wherein, the fiber prepreg yarn in S1 is UHMWPE fiber prepreg yarn.

[0063] Alternatively, the fiber prepreg yarn described in S1 includes carbon fiber prepreg yarn and UHMWPE fiber prepreg yarn. The carbon fiber prepreg yarn is firstly used to lay multiple layers to form a carbon fiber composite layer, and then the UHMWPE fiber prepreg yarn is used to lay multiple layers on the carbon fiber composite layer to form a composite helmet embryo.

[0064] The examples 1 and 2 implemented according to the present invention and the comparative examples implemented according to the prior art layup molding method are as follows:

[0065] Example 1

[0066] A wound composite material helmet, wherein the UHMWPE fiber prepreg yarn is sequentially laid and wound onto a core mold at a winding angle of 45° / -45° by the device of the present invention, and finally pressed and compounded by the device of the present invention to prepare a UHMWPE fiber wound composite material helmet with a thickness of 9 mm. The bulletproof performance of the composite material helmet prepared by this embodiment can reach the GJB293-2012 standard level 2, and no penetration is achieved in the case of 5 effective hits, and the bullet mark height (such as Figure 3 The V50 value for protection against 1.1g fragments can reach 1110m / s.

[0067] Example 2

[0068] A wound composite material helmet, wherein the carbon fiber prepreg yarn is firstly laid on a core mold in sequence at a winding angle of 45° / -45° by using the device of the present invention, and a predetermined number of layers are laid, and then the UHMWPE fiber prepreg yarn is laid on the glass fiber layer at a winding angle of 45° / -45°, and finally the UHMWPE fiber / carbon fiber wound composite material helmet with a thickness of 8.9 mm is prepared by pressing and compounding with the device of the present invention. The bulletproof performance of the composite material helmet prepared by this embodiment can reach the GJB293-2012 standard level 2, and no penetration is achieved in the case of 5 effective hits, and the bullet mark height (such as Figure 3 The V50 value for protection against 1.1g fragments can reach 1115m / s.

[0069] Comparative Example 1

[0070] The UHMWPE fiber prepreg is cut into impeller-shaped sheets with multiple cutouts around the periphery by using the existing technology, and then the sheets are laid on the mold in sequence by stacking the cutouts in a staggered manner, and then molded to obtain a UHMWPE fiber composite helmet with a thickness of 9 mm. The bulletproof performance of the composite helmet prepared by this comparative example can reach level 2 of the GJB293-2012 standard. Although no penetration is achieved in the case of 5 effective hits, the bullet mark height (such as Figure 3 The V50 value for protection against 1.1g fragments is only 880m / s.

[0071] In summary, compared with the prior art, it can be seen that the wound composite helmet formed by the device of the present invention not only has improved ballistic impact resistance, but also significantly reduces the height of the bullet mark after the ballistic impact.

[0072] It should be noted that for the sake of clear display, the cables connected to the motor 41 and the control module that controls the motor are omitted in the attached drawings; in addition, the spinning mechanism that cooperates with the male mold 4 of the mold mechanism to lay the fiber prepreg yarn on the male mold at a winding angle of 45° / -45° when rotating already exists in the prior art, for example, it can be achieved by using an industrial robot, which is not the focus of the present invention and is not shown in the figure.

[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
