Description

Technical Field

[0001] This invention relates to a demolding and extraction device and method for a hat-shaped reinforced wall panel forming airbag. Background Technology

[0002] With the development of China's domestically produced large aircraft and unmanned aerial vehicle (UAV) industries, hat-shaped stiffened panel components are widely used in the aerospace field due to their superior mechanical properties. For example... Figure 1 As shown, the hat-shaped stiffened panel is a typical structure for current passenger aircraft fuselage panels. For example, the front and rear fuselage panels of the C919 aircraft both use this structure.

[0003] The preparation of hat-shaped stiffened panels requires the use of co-curing molding process to improve the overall structural integrity of the parts. The main characteristics of the co-curing molded hat-shaped stiffened panels are as follows: (1) an airbag is used as the core mold to form its hat-shaped part. By introducing the pressure of the autoclave into the airbag, the pressure of the hat-shaped part is uniform and the molding quality is good; (2) a pressure pad is used to uniformly press the skin. Through the stiffness designability, the pressure transmission of the product in the area of ​​severe delamination or transition can be met, and the molding quality of the product can be guaranteed. At present, the hat-shaped stiffened panel products manufactured by co-curing molding technology have all passed multiple quality tests such as profile, axis, thickness, porosity, and ultrasonic non-destructive testing. All indicators meet the engineering requirements of product model, acceptance technical conditions, airworthiness and installation. Nowadays, this co-curing molding technology has been extended to the key technology research of the test piece of the self-controlled and controllable automatic wire laying panel of the rear fuselage section of the CR929 wide-body passenger aircraft, and has been successfully verified in the 1-meter wide-body rear fuselage panel.

[0004] Currently, after the cap-shaped reinforced panel is formed, the airbag is mainly removed manually. However, because the airbag is located in a cap-shaped structure that is closed on three sides, and because the cap-shaped part of the panel is thin and long, the airbag adheres tightly to the inner wall of the cap cavity after forming in the autoclave. It requires enormous external force to remove it, making airbag demolding difficult, especially for large cap-shaped reinforced panel parts. In such cases, it requires more than a dozen workers to pull the airbag out, resulting in extremely high labor costs. A more significant problem is that manual removal can also lead to uneven force distribution, causing the airbag to break inside the cavity and rendering the part unusable.

[0005] Therefore, how to easily and effectively demold the airbag after the hat-shaped reinforced wall panel is formed remains an urgent problem to be solved. Summary of the Invention

[0006] To address the aforementioned problems with airbag demolding after the formation of the hat-shaped reinforced wall panel, and to achieve the aforementioned technical objectives, this invention provides a demolding and extraction device and method for the airbag in the hat-shaped reinforced wall panel. A power mechanism drives an extraction actuator to uniformly extract the airbag from the hat-shaped cavity, effectively solving the above-mentioned problems and significantly reducing labor costs, thus achieving the requirements of mechanized and standardized production of the parts. The specific technical solution is as follows:

[0007] First, the present invention provides a demolding and extraction device for an airbag in a hat-shaped reinforced wall panel, comprising a base platform, an extraction actuator disposed on the base platform, and a drive mechanism for providing power to the extraction actuator; a baffle is provided at the front end of the base platform, and an airbag clamp is provided at the front end of the extraction actuator; the cured hat-shaped reinforced wall panel is placed at the front end of the baffle, and the airbag exposed outside the cavity of the hat-shaped wall panel is clamped on the airbag clamp, and the extraction actuator is driven by the drive mechanism to extract the airbag at a uniform speed.

[0008] The aforementioned cap-shaped reinforced wall panel forming airbag demolding and extraction device has a hydraulic press as the driving mechanism and a hydraulic telescopic rod as the extraction execution mechanism, which includes a hydraulic cylinder and a telescopic rod body built into the hydraulic cylinder. The hydraulic telescopic rod is set on the platform of the base platform through a sliding base, and the end of the telescopic rod body faces the baffle at the front end of the base platform. The hydraulic press is mounted above the extraction execution mechanism through a frame and is connected to the oil hole on the hydraulic cylinder through a hydraulic oil pipe to drive the telescopic rod body to extend and retract.

[0009] The aforementioned cap-shaped reinforced wall panel molding airbag demolding and extraction device includes a sliding base comprising two longitudinally fixed sliding grooves on a base platform and a base plate that is clamped on the sliding grooves and can slide along the sliding grooves; the base plate is also provided with a clamp to fix the hydraulic telescopic rod to the base plate; the front end of the base plate is provided with a limiting stop to limit the installation of the hydraulic telescopic rod and to limit and guide the telescopic movement of the telescopic rod body; the base plate is fixed to the sliding groove by a pin.

[0010] The aforementioned cap-shaped reinforced wall panel molding airbag demolding and extraction device includes an airbag clamp with a segmented design, comprising a first clamping claw body and a second clamping claw body, and a connecting rod for connecting to a hydraulic telescopic rod; the first clamping claw body and the second clamping claw body are connected and clamped together by bolts to hold and fix the airbag exposed outside the cavity of the cap-shaped wall panel; the inner surfaces of the first clamping claw body and the second clamping claw body are provided with serrated protrusions; the connecting rod is fixed on the body of one of the claw bodies.

[0011] The aforementioned hat-shaped reinforced wall panel molding airbag demolding and extraction device has a buffer pad in front of the baffle at the front end of the base platform to prevent damage during the installation and fixing of the hat-shaped wall panel and during the extraction of the airbag.

[0012] The aforementioned cap-shaped reinforced wall panel molding airbag demolding and extraction device also includes a vacuum pump, which is used to remove the gas inside the airbag, causing it to contract and separate from the inner wall of the cap-shaped cavity before extraction.

[0013] The aforementioned cap-shaped reinforced wall panel molding airbag demolding and extraction device has multiple sets of rollers with foot brakes under its base platform, and a pull rod handle at the rear end of the base platform for moving the device.

[0014] Secondly, this invention provides a method for demolding an airbag from a hat-shaped reinforced panel. The method uses the aforementioned extraction device to extract the airbag from the hat-shaped cavity of the hat-shaped reinforced panel component. Specifically, the extraction device is moved to one end of the cured hat-shaped reinforced panel component. The baffle at the front end of the base platform is aligned with one of the hat-shaped ribs, and the airbag with its end exposed outside the hat-shaped cavity is clamped onto the airbag clamp. The drive mechanism is activated to drive the extraction actuator to extract the airbag at a uniform speed. This method specifically includes the following steps:

[0015] 1) Remove the cured cap-shaped reinforced wall panel from the autoclave and place it in the designated demolding area;

[0016] 2) Push the extraction device to one end of the cap-shaped reinforced wall panel, select one of the cap-shaped ribs, and press the outer side of the baffle of the extraction device against the end of the cap-shaped rib.

[0017] 3) Adjust the position of the extraction actuator so that the stroke of the telescopic rod body is sufficient to extract the air bladder in the cap-shaped rib to be demolded;

[0018] 4) Connect the end of the airbag exposed outside the cavity of the cap-shaped rib to the vacuum nozzle, and start the vacuum equipment to extract the gas from the airbag.

[0019] 5) Simultaneously start the drive mechanism to bring the front end of the telescopic rod body of the extraction actuator close to the baffle, and clamp the end of the airbag to be extracted through the airbag clamp.

[0020] 6) Restart the hydraulic press of the drive mechanism to drive the telescopic rod body back, thereby extracting the airbag;

[0021] 7) After the airbag is removed, release the airbag clamp, remove the airbag, and transfer the removal device to another cap-shaped rib to be demolded. Repeat steps 2) to 6) until all airbags on the cap-shaped ribbed panel are removed.

[0022] The aforementioned method for demolding the airbag formed by the hat-shaped reinforced wall panel includes using multiple extraction devices to extract the airbag simultaneously; wherein, after vacuuming in step 4), the pressure inside the airbag is -50 to -100 kPa; and the pulling force for extracting the airbag in step 6) is 500 to 1000 N.

[0023] The beneficial effects of this invention are as follows:

[0024] 1) Through reasonable design, this invention enables the demolding of the airbag in the hat-shaped reinforced wall panel by using a mechanical device. This not only significantly reduces labor costs, but also uses a power mechanism to drive the extraction actuator to uniformly extract the airbag from the hat-shaped cavity, effectively solving the problem of airbag breakage due to uneven force. It also provides favorable conditions for the mechanized and standardized production of hat-shaped reinforced wall panel parts.

[0025] 2) The device of the present invention uses a hydraulic unit as the driving mechanism. The hydraulic control system regulates the flow direction, pressure and flow rate of the oil in the hydraulic system through the hydraulic control valve, so that the driven extraction actuator obtains a suitable motion direction, thrust (torque) and motion speed (rotation speed), etc., to adapt to the demolding and extraction of different specifications of hat-shaped stiffened wall panel forming airbags.

[0026] 3) The device of the present invention, by setting a sliding base, not only provides support for the extraction actuator, but also enables the airbag extraction device to adapt to the extraction of airbags of different lengths. During the extraction process, the hydraulic rod is fixed to prevent left and right swaying, ensure the direction of airbag extraction, and ensure that the airbag is subjected to uniform force and safely pulled out.

[0027] 4) The vacuum device in this invention uses a vacuum pump to remove the gas from the airbag, causing it to contract and separate from the inner wall of the cap-shaped cavity, further ensuring that the airbag can be easily extracted.

[0028] 5) The airbag clamp of the device of the present invention not only has serrated protrusions in its inner cavity to clamp the airbag so that it will not fall off during extraction, but the clamp is also designed in a split type and the size is adjustable so that it can be used to match airbags of different sizes, thus expanding the applicability of the extraction device.

[0029] 6) The front end baffle of the device of the present invention can not only position and fix the cap-shaped wall panel when the airbag is withdrawn, but also a buffer pad is provided in front of the baffle to prevent the parts from being damaged.

[0030] 7) The device of the present invention is also equipped with universal wheels with brakes on the base plate. It can be moved freely by the handle to extract the airbags at different positions of the hat-shaped stiffened wall panel. The operation is flexible, making the device adaptable to more scenarios, and can avoid moving the hat-shaped stiffened wall panel itself, saving manpower and avoiding damage during the handling of the parts.

[0031] 8) The demolding method of this invention involves fixing the buffer pad in front of the stop block, placing the cured hat-shaped reinforced wall panel in front of the stop block, and selecting one airbag for extraction. The airbag exposed outside the cavity of the hat-shaped wall panel is clamped by the screws of the airbag adjusting clamp, and the end of the airbag is connected to the vacuum nozzle. Then, the hydraulic device is started to drive the telescopic rod to extract the airbag from the cavity of the hat-shaped reinforced wall panel at a uniform speed. The operation is simple, and multiple devices can be used at the same time. The extraction of airbags is efficient and safe, and has good application value. Attached Figure Description

The drive mechanism 3 drives the pull-out actuator 2 to pull out the airbag at a uniform speed, thereby effectively solving the problem of airbag breakage due to uneven force, and providing favorable conditions for the mechanized and standardized production of cap-shaped reinforced wall panel parts.

[0041] In this embodiment, the driving mechanism 3 is a hydraulic press; the extraction actuator 2 is a hydraulic telescopic rod, which includes a hydraulic cylinder 21 and a telescopic rod body 22 built into the hydraulic cylinder 21; the hydraulic telescopic rod is set on the platform of the base platform 1 through the sliding base 6, and the end of the telescopic rod body 22 faces the baffle 4 at the front end of the base platform 1; the hydraulic press is installed above the extraction actuator 2 through the frame 7, and is connected to the oil hole 211 on the hydraulic cylinder 21 through the hydraulic oil pipe 8 to drive the telescopic rod body 22 to extend and retract.

A limiting block 64 is provided at the front end of the base plate 62 to limit the installation of the hydraulic telescopic rod and to limit and guide the extension and retraction movement of its telescopic rod body 22. The base plate 62 is fixed to the sliding grooves 61 by pins, and the position of the extraction actuator 2 on the sliding base 6 is adjusted according to the length of the airbag to be extracted. The clamp 63 can be customized according to the size of the extraction actuator 2 and is detachable, facilitating the replacement and maintenance of the extraction actuator 2. Meanwhile, the sliding base not only provides support for the extraction actuator, but also allows the airbag extraction device to adapt to the extraction of airbags of different lengths. During the extraction process, the hydraulic rod is fixed to prevent left and right swaying, ensure the direction of airbag extraction, and ensure that the airbag is subjected to uniform force and safely pulled out.

[0043] In this embodiment, the airbag clamp 5 is a segmented design, such as... Figure 4 As shown, it includes a first gripper body 51 and a second gripper body 52, and a connecting rod 53 for connecting to the hydraulic telescopic rod. The first gripper body 51 and the second gripper body 52 are connected and clamped together by bolts 54 to hold and fix the airbag exposed outside the cavity of the cap-shaped wall panel. The inner surfaces of the first gripper body 51 and the second gripper body 52 are provided with serrated protrusions 55. The connecting rod 53 is fixed to the body of one of the grippers. The connecting rod 53 can be detachably connected to the telescopic rod body, for example by clamping or screwing, so as to replace the airbag clamp 5 later, facilitate maintenance and adapt to airbags of different sizes. The serrated protrusions in its inner cavity can clamp the airbag tightly so that it does not fall off during withdrawal. The clamp is designed as a split type, and its size is adjustable, so it can be used to match airbags of different sizes, expanding the applicability of the withdrawal device.

[0044] In addition, in this embodiment, a buffer pad is provided in front of the baffle 4 at the front end of the base platform 1 to prevent damage during the installation and fixing of the cap-shaped wall panel and during the extraction of the airbag. The buffer pad can be a rubber pad, silicone pad, latex pad or sponge pad, etc., and can be glued to the baffle 4. Its thickness can be designed as needed, and the thickness is 50-100mm.

[0046] Example 2

[0047] This embodiment describes the extraction of a hat-shaped reinforced wall panel using the extraction device described in Embodiment 1. Figure 5 As shown, the hat-shaped reinforced wall panel contains 14 hat-shaped reinforcing ribs, with the longest hat-shaped reinforcing rib being 2.9 meters long. It takes several people working together to pull out the airbag, and there is a significant risk that the airbag will break and cause the part to be scrapped.

[0048] This embodiment demonstrates the process of extracting the airbag using the device of the present invention; that is, the extraction device described in Embodiment 1 is moved to one end of the cured cap-shaped reinforced wall panel, the baffle 4 at the front end of the base platform 1 is aligned with one of the cap-shaped ribs, and the airbag with the end of the cap-shaped rib exposed outside the cavity of the cap-shaped wall panel is clamped on the airbag clamp 5. The drive mechanism 3 is activated to drive the extraction execution mechanism 2 to extract the airbag at a uniform speed. The specific extraction process includes the following steps:

[0049] 1) Remove the cured cap-shaped reinforced wall panel from the autoclave and place it in the designated demolding area.

[0050] 2) Push the extraction device to one end of the cap-shaped reinforced wall panel, select one of the cap-shaped ribs, and press the outer side of the baffle 4 of the extraction device against the end of the cap-shaped rib.

[0051] 3) Adjust the position of the extraction actuator 2 so that the stroke of the telescopic rod body 22 is sufficient to extract the air bladder in the cap-shaped rib to be demolded.

[0052] 4) Connect the end of the airbag exposed outside the cavity of the cap-shaped wall panel to the vacuum nozzle, and start the vacuum pumping device 9 to extract the gas in the airbag. The pressure inside the airbag reaches -50 to -100 kPa. In this embodiment, it is controlled to be -80 kPa.

[0053] 5) Simultaneously start the drive mechanism 3, so that the front end of the telescopic rod body 22 of the extraction actuator 2 approaches the baffle 4, and the airbag end to be extracted is clamped by the airbag clamp 5.

[0054] 6) Restart the hydraulic press of drive mechanism 3 to drive the telescopic rod body 22 back to the starting position, thereby extracting the airbag; the pulling force is 500-1000N, and 600N in this embodiment.

[0055] 7) After the airbag is removed, release the airbag clamp 5, remove the airbag, and transfer the removal device to another cap-shaped rib to be demolded. Repeat steps 2 to 6 until all airbags on the cap-shaped reinforced wall panel are removed.

[0056] In this embodiment, one extraction device is used to extract the airbags one by one. However, in order to speed up the extraction, multiple extraction devices can be used simultaneously, which greatly saves manpower and extraction time. Moreover, the extracted airbags do not break, and the effect is remarkable.

[0057] Overall, the device of this invention is rationally designed, enabling the demolding of the airbag from the hat-shaped reinforced wall panel using a mechanical device. This not only significantly reduces labor costs but also effectively solves the problem of airbag breakage due to uneven stress by using a power mechanism to drive the extraction actuator to uniformly extract the airbag from the hat-shaped cavity. Furthermore, it provides favorable conditions for the mechanized and standardized production of hat-shaped reinforced wall panel parts. Moreover, the demolding method of this invention is simple to operate; multiple devices can be used simultaneously, and the extraction of the airbag is efficient and safe, demonstrating significant practical value.
