Description

Technical Field

[0001] This invention relates to the field of aerospace technology, and more specifically to an automatic punching mold and method for producing aerospace housings. Background Technology

[0002] Currently, aircraft manufacturing generally adopts a segmented manufacturing and then overall assembly method. Therefore, the outer skin must be manufactured in sections along the longitudinal direction of the aircraft. However, if a single piece is bent and formed in the circumferential direction, it is difficult to ensure a perfect fit with the aircraft frame. At the same time, if the curvature of a single piece of skin is too large, it will lead to excessive residual stress during processing deformation, which can easily cause stress corrosion and a decrease in fatigue strength. Generally, the curvature of a single piece of skin should not exceed 120 degrees. Therefore, the single piece of skin in modern civil aircraft is generally no more than 10 meters in the longitudinal direction and no more than 100 degrees in the circumferential direction. Stamping is currently the main method for producing aircraft shells. It has good stamping forming effect, low power consumption, and simple operation.

[0003] However, existing aircraft housing processing molds generally do not have the function of fixing materials. Due to the large size of aircraft housings, the material is prone to swaying during the stamping process, which affects the processing accuracy of the housing. Moreover, most of the existing processing molds are of fixed size, which makes it difficult to apply to the processing of housings of different sizes and shapes. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides an automatic punching mold and method for producing aerospace housings.

[0005] The technical solution of the present invention is: an automatic punching boss mold for producing aerospace housings, comprising a bracket and a mold assembly and a limiting assembly movably disposed inside the bracket;

[0006] The mold assembly includes a female mold disposed at the bottom of the support, a push plate slidably engaged inside the support and located at the upper end of the female mold, and a male mold disposed on the lower bottom surface of the push plate; the upper end surface of the female mold is provided with a forming cavity adapted to the male mold; the push plate is slidably engaged with the support through a first sliding sleeve, and a return spring is sleeved on the support and abuts against the first sliding sleeve; an extrusion column is provided on the upper end surface of the push plate, penetrating the support and slidably engaged with the support;

[0007] The limiting assembly includes a movable frame that is slidably engaged inside the bracket and located between the female and male molds, limiting clamps that are slidably engaged on both sides inside the movable frame, and a micro motor that is set on the upper end face of the movable frame and provides power to the limiting clamps; the movable frame is slidably engaged with the bracket through a second sliding sleeve, and a compression spring that abuts against the second sliding sleeve is fitted on the bracket; both ends of the two limiting clamps are provided with threaded seats, and the internal threads of the threaded seats on the two limiting clamps are turned in opposite directions; the output shaft of the micro motor is provided with a drive screw that is threadedly connected to the threaded seats on the same side of the two limiting clamps.

[0008] Furthermore, it also includes guide components disposed on the female mold and located on both sides of the molding cavity; the upper end face of the female mold is provided with a recess for accommodating the guide components; the guide components include a mounting bracket rotatably engaged inside the recess, several guide rollers equidistantly distributed at the top of the mounting bracket, and a first electric push rod disposed at the bottom of the recess and providing power to the mounting bracket; a connecting gear is provided at the connection between the mounting bracket and the recess, and a toothed plate slidably engaged at the bottom of the recess, meshing with the connecting gear and connected to the first electric push rod;

[0009] Explanation: When the housing plate is pressed into the molding cavity, the guide rollers on the two mounting brackets guide the housing plate to avoid friction and damage between the housing plate and the female mold; when the male mold gradually approaches the female mold, the first electric push rod pushes the toothed plate to move inside the sink. Since the connecting gear and the toothed plate are meshed, the mounting bracket gradually rotates and is stored inside the sink during the rotation of the connecting gear.

[0010] Furthermore, each guide roller is fitted with a rubber ring on its exterior;

[0011] Note: By setting rubber rings on the guide rollers, the surface of the housing plate can be protected.

[0012] Furthermore, the upper surface of the female mold is provided with a cutting groove; the bottom surface of the push plate is slidably engaged with an annular cutting blade corresponding to the upper and lower positions of the cutting groove via a connecting rod; the upper surface of the push plate is provided with a pressure plate connected to the connecting rod and sleeved on the outside of the extrusion column via an extrusion sleeve; the extrusion sleeve is provided with an arc-shaped groove; a drive sleeve is rotatably engaged on the extrusion column and above the extrusion sleeve; the drive sleeve is provided with an arc-shaped protrusion that can engage with the arc-shaped groove; a second electric push rod is movably hinged to the upper surface of the push plate and movably connected to the drive sleeve;

[0013] Explanation: After the housing sheet is extruded and formed, the second electric push rod pushes the drive sleeve to rotate on the extrusion column. The arc protrusion on the drive sleeve and the arc groove on the extrusion sleeve engage, causing the pressure plate to move downward along the push plate and push out the annular cutting knife. The cooperation between the annular cutting knife and the cutting groove is used to cut and shape the excess material on the edge of the formed housing, which helps to improve the processing efficiency of the housing.

[0014] Furthermore, the insertion rod is fitted with retraction springs that abut against the pressure plate and the push plate respectively;

[0015] Note: By incorporating a retraction spring, the annular cutter is always positioned inside the push plate when not in use, thereby improving the safety of using the annular cutter.

[0016] Furthermore, a ball bearing is rotatably engaged on the arc-shaped protrusion;

[0017] Note: By incorporating ball bearings, the resistance encountered when the arc-shaped protrusion slides inside the arc-shaped groove is reduced, thereby reducing the operating load of the second electric push rod.

[0018] Furthermore, a replacement mold is movably engaged inside the female mold, and the forming cavity is set on the replacement mold; the male mold is movably engaged with the push plate.

[0019] Note: By setting up a replacement mold, it is easy to replace female molds of different sizes and shapes, making the present invention applicable to the processing of various types of machine housings and improving the applicability of the present invention.

[0020] Furthermore, the inner wall of the molding cavity and the outer surface of the male mold are both polished.

[0021] Note: Polishing the molding cavity and male mold can prevent defects from occurring during the extrusion of the casing sheet.

[0022] Furthermore, slots are provided on the opposite sides of both limiting clamps;

[0023] Note: By setting a slot on the limit clamp, the connection stability between the limit clamp and the housing plate is improved.

[0024] This invention also provides a method for using an automatic punching boss mold in the production of aerospace housings, comprising the following steps:

[0025] S1. Connect the micro motor to an external power source;

[0026] S2. Place the housing plate on the moving frame and start the micro motor. Use the micro motor to drive the drive screw to rotate, so that the two limit clamps move closer to each other and limit and fix the housing plate.

[0027] S3. Fix the bracket on the press and make the extrusion column abut against the output end of the press; start the press, and the press causes the push plate to slide inside the bracket through the extrusion column, using the forming cavities on the male and female molds to extrude the shell sheet into shape; when the push plate moves inside the bracket, the moving frame moves with the push plate, and during the extrusion of the shell sheet, the two limit clamps move closer and closer.

[0028] Compared with the prior art, the beneficial effects of the present invention are reflected in the following aspects:

[0029] First, the automatic punching boss mold of the present invention has a reasonable structural design. The female mold and the male mold are set inside the bracket at the same time. The bracket guides the movement of the male mold, so that the male mold and the forming cavity on the female mold fit precisely. At the same time, the limiting component is used to limit and fix the processed sheet material, which improves the processing accuracy of the space shuttle shell.

[0030] Secondly, by setting a guide component on the female mold and using the guide rollers on the mounting frame to guide the sheet metal, the present invention avoids the edge of the sheet metal from being damaged or scrapped due to friction with the female mold during the stamping process, thereby improving the reliability of the automatic punching boss mold of the present invention.

[0031] Third, after the machine housing is stamped, the automatic punching boss mold of the present invention uses a ring cutting blade to cut and trim the excess material at the edge of the formed machine housing, which simplifies the production process of the machine housing and improves production efficiency.

[0078] S1. Connect the micro motor 32, the first electric push rod 42 and the second electric push rod 53 to an external power source respectively.

The arc protrusion 520 on the drive sleeve 52 and the arc groove 5100 on the extrusion sleeve 510 engage, causing the pressure plate 51 to move downward along the push plate 21 and push out the annular cutting knife 5. The annular cutting knife 5 and the cutting groove 202 work together to cut and shape the excess material on the edge of the formed casing.

[0082] It should be noted that the micro motor 32, the first electric push rod 42 and the second electric push rod 53 used in this invention all adopt existing technology and are not specifically limited here. Appropriate products can be selected according to actual needs.
