Description

Technical Field

[0001] This invention relates to the field of composite material product manufacturing technology, specifically to a bonding device and method for bonding end face flanges of composite material pressure-resistant shells with molds. Background Technology

[0002] Composite material pressure hulls are commonly used underwater pressure-bearing devices that replace metal materials, housing components requiring protection at atmospheric pressure. Currently, the application of composite material pressure hulls in underwater applications is relatively mature. Due to the inherent properties of composite materials, the bonding and load-bearing capacity between two materials of equal quality is relatively poor. Currently, metal connections are typically used for assembly. For composite material pressure hulls, metal flanges are usually bonded to their end faces, and the two ends of the hull are connected via flanges for assembly. Due to molding process considerations, some products require subsequent processes without demolding after flange bonding. Therefore, the bonding effect of the end face flanges directly affects the assembly accuracy, especially when bonding longer hulls or when the angle difference between the flanges at both ends is small, significantly increasing the difficulty of bonding with a mold. To meet this requirement, it is necessary to design a bonding device and method for the end face flanges of composite material pressure hulls with a mold that effectively improves bonding accuracy. Summary of the Invention

[0003] To address the problems existing in the above-mentioned background technology, the present invention provides a bonding device and method for bonding end face flanges of composite material pressure-resistant shells with molds. The bonding device has a reasonable structural design, is easy to use, has high bonding accuracy, good reliability, and has multi-size bonding function, realizes bonding with molds, and improves production efficiency.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0005] A molded composite material pressure-resistant shell end face flange bonding device is used for bonding end face flanges of molded pressure-resistant shells, including a mold adjustment platform, a flange connection mechanism, a flange adjustment platform and a support wooden support;

[0006] The mold adjustment platform includes a support frame I and a semi-circular bracket on the support frame I. The mold end shaft is placed in the groove of the semi-circular bracket to prevent the mold from rolling during the bonding process. A screw is provided below the semi-circular bracket and is fixedly connected to the top platform of the support frame I. An adjusting nut is provided at the connection point. By adjusting the position of the nut, the height of the groove of the semi-circular bracket is raised or lowered, thereby adjusting the height of the mold and making the mold axis parallel to the plane of the platform. Furthermore, the bottom of the support frame of the mold adjustment platform is provided with an adjusting foot I. By setting the adjusting foot, the interference of uneven ground on which the device is placed is offset.

[0007] The flange connection mechanism is a movable and detachable flange used to fix the end face flange to be bonded. The end face flange to be bonded is generally provided with threaded holes, through holes and positioning holes. The flange connection mechanism is connected to the end face flange by bolts or screws and fixed as one piece. The positioning holes and fixing holes of the two are matched. The positioning holes or their sizes may vary slightly depending on the type of end face flange. The main function is to fix the position of the end face flange.

[0008] The flange adjustment platform includes an adjustable positioning platform, a pressurization / depressurization section, and a support frame II. The pressurization / depressurization section consists of a fixed vertical baffle, a connecting screw, and a flange axial displacement adjusting nut. The fixed vertical baffle is fixed to the outer wall of the pressure-resistant housing end through a central through hole. The flange connection mechanism and the end flange are integrated and pass through the mold, connected to the fixed vertical baffle via the connecting screw and the flange axial displacement adjusting nut. Positioning and bonding are achieved by moving the flange by tightening and loosening the flange axial displacement adjusting nut. The support frame II is placed below the mold, and adjustable positioning platforms are symmetrically distributed on both sides of the support frame II. Each side of the flange connection mechanism has a boss, and the bottom surfaces of the two bosses are respectively placed on the adjustable positioning platforms on both sides of the support frame II. They can move a wide range along the platform (axial) direction and also serve to adjust the circumferential angle of the flange. Furthermore, the bottom of the support frame II is provided with adjustable feet II to counteract the interference of uneven ground where the device is placed.

[0009] The supporting wooden tray consists of a wooden base and a surface felt, serving as a temporary place for molds and products. The number and spacing depend on the product's weight and length; that is, the heavier the product, the more supporting wooden trays are needed. The spacing depends on the product's length; the heavier and longer the product, the smaller the spacing. The shape is determined by the product's shape and matches its appearance.

[0010] Furthermore, the mold adjustment platform, flange connection mechanism, and flange adjustment platform are symmetrically distributed at both ends of the product with mold.

[0011] Furthermore, each side of the support frame II of the flange adjustment platform is provided with an adjustable positioning platform, and each end of the pressure-resistant housing with mold is provided with two adjustable positioning platforms for controlling the rotation of the flange. Each adjustable positioning platform has several positioning platform adjusting nuts with adjustable position and height. By tightening or loosening the nuts, the four platforms at both ends are located on the same plane and are all coaxial with the mold, thereby realizing the circumferential positioning of the flanges at both ends.

[0012] Furthermore, there are six connecting screws: two at the top and two at the bottom, and one on each side.

[0013] Furthermore, the present invention also provides a method for bonding the end face flange of a composite material pressure-resistant shell using the above-mentioned device with a mold, comprising the following steps:

[0014] (1) Connect and fix the end face flange to be bonded to the flange connection mechanism with bolts or screws, and then put it back into the mold after fixing it into a whole.

[0015] (2) Place the pressure-resistant shell product with mold on the support wooden support. Place the mold adjustment platform at one or both ends of the mold. Place the shaft head at the end of the mold in the semi-circular bracket groove on the mold adjustment platform to prevent the mold from rolling during the bonding process. Place the flange adjustment platform between the mold and the mold adjustment platform.

[0016] (3) By adjusting the adjustable positioning platform in the flange adjustment platform, the plane formed by the adjustable positioning platform is parallel to the mold axis and the bottom surface of the bosses on both sides of the flange connection mechanism is in contact with the adjustable positioning platform to achieve circumferential positioning of the flanges on both sides.

[0017] (4) Adjust the pressurization / depressurization part of the flange adjustment platform to drive the flange connection mechanism to move towards the end face of the pressure-resistant housing. After the flange of the bonding end face is pressed against the pressure-resistant housing, maintain the pressurization state until it is completely bonded.

[0018] In step (4), the flange axial displacement adjusting nut is adjusted, and tightening the nut applies pressure, which drives the flange connection mechanism to move towards the end face of the pressure-resistant housing; the pressure is maintained for 24 hours, and the adhesive is completely cured, indicating that it has been completely bonded.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) This invention can improve the bonding quality of the end face flange of the composite pressure shell. After bonding with mold, the deformation of the product itself is reduced. Since the mold length exceeds the product, the mold can be directly operated during the preparation steps such as transportation, adjustment and bonding, which plays a role in protecting the product quality.

[0021] (2) The present invention adopts a split design, which improves the bonding applicability of the device. The position of the flange connection mechanism and the pressure / release mechanism in the flange adjustment platform can be adjusted separately according to different shell sizes and usage requirements to meet various requirements and reduce usage costs.

The device features a symmetrically distributed adjustable positioning platform. A boss is located on each side of the flange connection mechanism, with the bottom surfaces of these bosses resting on the adjustable positioning platforms on either side of the support frame II. These platforms can move extensively along the platform's (axial) direction and adjust the flange's circumferential angle. Furthermore, the support frame II has adjustable feet at its bottom to counteract uneven ground conditions. Four height-adjustable platforms and pressurization / depressurization sections are distributed at both ends of the device. Each platform has several height-adjustable adjustment structures. By tightening or loosening the nuts, the four platforms are aligned on the same plane, and the bottom surfaces of the bosses on both sides of the connection mechanism rest on the flange adjustment platform, achieving circumferential positioning of the flanges at both ends.

[0033] like Figure 5 As shown, the flange connection mechanism 3 is a movable and detachable flange used to fix the end face flange to be bonded. The end face flange to be bonded is generally provided with threaded holes, through holes and positioning holes.
