Description

Technical Field

[0001] This invention relates to the field of aircraft mold processing technology, and in particular to a partition processing device and processing method for a composite workstation. Background Technology

[0002] Mechanical and aerospace system structural components include reinforced partition-type parts with flanged structures; see [link / reference]. Figure 6 A certain type of aviation-grade reinforced bulkhead has a flat plate structure with long flanges at its edges. The plate structure has multiple process holes of different shapes, such as round and elliptical holes, which are also flanged. These parts have uniform wall thickness and are subject to certain dimensional accuracy requirements due to assembly relationships. However, the overall processing system has poor rigidity and is prone to deformation during processing. The traditional processing solution is to use multiple sets of molds for processing, with flanging, trimming, cutting, and punching handled by different molds. Each mold is responsible for processing different states. Although multiple sets of molds can achieve the final product effect, the mold investment cost is high and the part processing cycle is long. When mass production is needed, this processing mode can no longer meet the production and delivery requirements. Summary of the Invention

[0003] The purpose of this invention is to provide a processing device and method with high processing efficiency, stable and reliable quality, and capable of meeting the requirements of batch production processing of composite workstations.

[0004] Technical solution: In one aspect, the present invention proposes a processing device for reinforcing partitions, the processing device comprising an upper support frame, an upper template, a lower template, an upper die punch, an upper die concave, a lower die first punch, a lower die second punch, a lower die third punch, a guide post, a guide sleeve, and a lower support frame;

[0005] The upper support frame and lower support frame are used to fix the upper template and lower template respectively, and are connected to the machine tool to realize the motion control of the upper and lower templates; the upper template and lower template are connected by guide columns and guide sleeves to realize accurate control of the movement direction;

[0006] The upper template is provided with a punch and a die for stamping the reinforcing partition; the outer ring of the punch and die is the upper die punch, and the inner ring is the upper die cavity; the upper end face of the lower template is provided with a lower die first punch, a lower die second punch, and a lower die third punch at a position opposite to the upper template punch and die; wherein the lower die third punch is located between the lower die first punch and the lower die second punch;

[0007] After the upper and lower templates are aligned, the punch and die of the upper template match the punch on the lower template to form the required process holes on the reinforcing partition. During the punching process, the upper and lower punches match to complete the punching and flanging while removing the excess material.

[0008] Furthermore, the lower die first punch matches the upper die punch and is used to punch the process holes required for reinforcing the partition; the lower die second punch is used to reinforce the flange at the process hole position of the partition; the upper end face of the lower die third punch forms a small step with the pressing edge position of the lower die second punch, which is used to reinforce the cut edge after the process hole of the partition is flanged.

[0009] Furthermore, the upper template is also equipped with a flanging punch for flanging the outer edge of the reinforcing partition according to the shape requirements of the reinforcing partition. Correspondingly, a pressure ring is also provided on the edge of the lower template. The pressure ring can move up and down. During processing, the pressure ring and the upper end face of the lower template form a step. When the flanging punch of the upper template is pressed down, the flanging work of the outer edge of the reinforcing partition is completed.

[0010] Furthermore, in the upper die, the upper die cavity can slide within the upper die punch to store the waste material formed during stamping.

[0011] Furthermore, the upper die cavity is connected to the upper template via a stripper screw, and the stripper screw is adjusted to achieve unloading.

[0012] Furthermore, the upper template has concave and convex dies, and the lower template has convex dies arranged in groups. The shape and number of each group are designed according to the needs of the reinforcing partition.

[0013] Furthermore, the upper support frame is also equipped with a transition plate and a discharge rubber. Multiple transition plates are assembled into a square box-shaped structure, and the discharge rubber is placed inside the box-shaped structure.

[0014] Furthermore, guide posts and guide sleeves are respectively provided at the four corners of the upper support frame and the lower support frame for guiding during the stamping process.

[0015] Furthermore, a rubber pad is provided between the upper support frame and the upper template.

[0016] Furthermore, a pressure ring is also provided on the lower template. On the one hand, it can provide beneficial friction during the part processing to prevent the part from wrinkling. On the other hand, after the part is processed, it can be pushed out of the lower template.

[0017] Another aspect of the present invention also provides a method for processing a reinforced partition, the method comprising the following:

[0018] S1. Fix the connecting parts of the processing device to the machine tool. During the return stroke of the machine tool, the slide on the machine tool rises to the top dead center and rises together with the upper template connected to the machine tool. The upper and lower templates of the processing device are completely separated. Place the reinforcing partition to be processed on the upper end face of the lower template and align it with the position of the required processing hole.

[0019] S2. Machine tool pressing: During machine tool pressing, the upper part of the processing device connected to the machine tool moves downward together. The upper die flanging punch contacts the workpiece first. As it continues to move downward, the outer ring of the reinforcing partition to be processed completes the deep drawing and flanging. When the upper die flanging punch contacts the lower die pressing ring, the outer ring of the workpiece completes the trimming work. During this process, the punch in the upper die platen moves downward and cooperates with the first punch of the lower die to complete the punching work of the reinforcing partition process hole. When the upper die punch contacts the second punch of the lower die, the flanging work is completed. As the upper die platen continues to move downward, the upper die punch cooperates with the third punch of the lower die to start the blanking action until the blanking work is completed. As the upper die platen continues to move downward, the blanked reinforcing partition process completes the flanging and trimming under the action of the second punch of the lower die.

[0020] S3. After processing is completed, the slide on the machine tool rises to the top dead center, the upper template connected to the machine tool rises with the machine tool, the upper and lower templates of the processing device separate, the processed reinforcing partition is taken out, and the processing waste is automatically removed at the same time.

[0021] Furthermore, to facilitate the removal and unloading of processed parts, a stripper plate is provided between the upper template and the upper support frame of the processing device. When the machine tool is reset, the stripper plate is pushed to reset. During the reset process, the stripper plate pushes out the die cavity of the upper template to realize the discharge of punching waste in the die cavity. A top plate is also provided between the lower template and the lower support frame. The top plate is connected to the pressure ring by a long screw. The movement of the top plate can push the pressure ring to move up and down.

[0022] Furthermore, a retaining ring is provided on the upper end face of the third punch of the lower die. The lower end of the retaining ring is connected to a screw. After the top plate moves upward to a certain stroke, it pushes against the short screw to move upward, thereby realizing the movement of the retaining ring and pushing out the waste material remaining in the flange punching in the retaining ring.

[0023] Technical effects of the present invention:

[0024] The processing device proposed in this invention utilizes the cooperative relationship between the punches and dies in the upper and lower templates to realize the outer edge flanging of the above-mentioned reinforcing partition, the punching of multiple process holes on the partition, and the flanging and trimming processes. It greatly reduces the amount of molds used, significantly improves processing efficiency, ensures good precision control, and provides stable and reliable quality. It can meet the processing requirements of mass production of reinforcing partitions with flanged structures without deformation. Attached Figure Description

Detailed Implementation

[0032] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. It should be noted that some (but not all) of the disclosed examples are shown in the drawings. In fact, many different examples can be described, and these examples should not be construed as limited to those set forth herein. Rather, these examples are described to further highlight the positive effects of the invention, and any aspects not detailed herein are considered to be well-known or conventional techniques in the art.

[0033] See appendix Figures 1-5 The specific design of a processing device for reinforcing partitions includes the following main components: upper pad 1, unloading rubber 3, upper template 5, pressure ring 27, lower template 28, lower pad 31, guide post 32, guide sleeve 33, the upper template also includes an upper die punch 5A, an upper die concave die 5B, and a flanging die 5C, and the lower template also includes a lower die first punch 28A, a lower die second punch 28B, and a lower die third punch 28C;

[0034] The upper shim 1 serves as the upper support frame, and the lower shim 31 serves as the lower support frame, which are used to fix the upper template 5 and the lower template 28 respectively. At the same time, they are connected to the machine tool to realize the motion control of the upper and lower templates. The upper and lower templates are connected by the guide column 32 and the guide sleeve 33 to realize the accurate control of the movement direction.

[0035] In the specific design, the upper template 5 is provided with punches and dies for stamping the reinforcing partition and a flanging punch 5C. The punches and dies can be designed in several groups according to the needs of the process hole. Each group includes an upper die punch 5A and an upper die cavity 5B. The outer ring of the punches and dies is the upper die punch 5A, and the inner ring is the upper die cavity 5B. The upper end face of the lower template 28 is provided with a lower die first punch 28A, a lower die second punch 28B, and a lower die third punch 28C at the relative position of each group of punches and dies in the upper template. The lower die third punch 28C is located between the lower die first punch 28A and the lower die second punch 28B. The lower die first punch 28A is a columnar structure similar in shape to the process hole, which can be a cylinder or an elliptical cylinder, and is used to match the upper die punch 5A in the upper template to realize the punching of the process hole.

[0036] Specifically, after the upper and lower templates are aligned, the punch and die of the upper template match the punch on the lower template to stamp the required process holes on the reinforcing partition. During the stamping process, the upper and lower punches match and move in opposite directions to complete the punching and flanging while removing excess material. The second punch 28B of the lower die is used to reinforce the flanging at the process hole position of the partition. The upper end face of the third punch 28C of the lower die forms a small step with the pressing edge position of the second punch 28B of the lower die to reinforce the cut edge after the process hole of the partition is flanged. In terms of specific design structure, the upper end face of the second punch 28B of the lower die is provided with... A boss is provided, and the upper edge of the boss adopts an arc-shaped transition structure; the corresponding lower die third punch 28C is an L-shaped ring structure with its upper end face slightly wider than the boss of the lower die second punch 28B; the boss of the lower die second punch 28B presses on the upper end face of the lower die third punch 28C, which on the one hand restricts the axial movement of the lower die third punch 28C, and on the other hand, the arc structure of the upper end face of the boss can serve as a flanging and trimming structure for the process hole. The edge of the upper end face of the lower die third punch 28C matches the outer edge of the upper die punch 5A to achieve automatic trimming after flanging.

[0037] In addition, due to the design requirement of the reinforcing partition having an outer edge flange, and the flange length being greater than the flange length at the process hole, in terms of specific design structure, the upper template is also equipped with a flange punch 5C for flanged outer edge of the reinforcing partition according to the shape requirements of the reinforcing partition. Correspondingly, the lower template 28 is also equipped with a pressure ring 27 on its edge. The pressure ring can move up and down. During processing, the pressure ring 27 and the upper end face of the lower template 28 form a step. The height of this step determines the flange length of the reinforcing partition. The outer diameter of the inner ring of the flange punch 5C is slightly larger than the outer diameter of the lower template 28 by about one material thickness. When the flange punch 5C of the upper template 5 is pressed down, the flanged outer edge of the reinforcing partition is completed.

[0038] During processing, the design of this invention also fully considers the problem of automatic waste removal to improve processing efficiency. After a reinforcing partition is processed and the finished product is removed, the waste is automatically removed. In terms of specific design, in the upper template, the upper die cavity 5B can slide inside the upper die punch 5A to store the waste generated during stamping. Since the upper template 5 is provided with a stripper rubber 3, which has a certain elasticity, a stripper screw is provided between the stripper rubber 3 and the upper die cavity 5B. When punching the process hole, the lower die first punch 28A moves upward and pushes against the upper die cavity 5B to move in the same direction. When the upper die cavity 5B moves, it pushes against the stripper screw and squeezes the stripper rubber 3. The punching waste is left between the lower die first punch 28A and the upper die cavity 5B. After punching is completed, the stripper rubber 3 rebounds, and the stripper screw can be adjusted to achieve unloading. When the upper template corresponds to multiple sets of dies, the stripper screws at the upper ends of multiple dies are connected to the same stripper plate, and the waste in multiple dies is discharged simultaneously through the same stripper plate.

[0039] In the waste unloading structure of the lower template processing, a top plate is set at the lower end of the lower template. The top plate can be connected to the machine tool to control the movement stroke. A pressure ring 27 is also set on the lower template. On the one hand, it can provide beneficial friction during the part processing to prevent the part from wrinkling. On the other hand, after the part is processed, it is ejected from the lower template. During the part ejection process, after the upper end face of the middle section of the top plate abuts against several unloading screws set on the lower template, the top plate drives the unloading screws to move in the same direction. The unloading screws are connected to the unloading retaining ring set on the upper end face of the inner ring of the third punch 28C of the lower mold. When the top plate ejects the reinforcing partition part, it drives the unloading screws to move to the highest point, which can automatically remove the waste material left on the unloading retaining ring after the process hole is turned and cut.

[0040] The method for processing a reinforcing partition using the aforementioned processing apparatus includes the following steps:

[0041] S1. Fix the connecting parts of the processing device to the machine tool. When the machine tool returns, the slide on the machine tool rises to the top dead center and rises together with the upper template 5 connected to the machine tool. The upper and lower templates of the processing device are completely separated. Place the reinforcing partition to be processed on the upper end face of the lower template 28 and align it with the position of the required processing hole. In specific design, corresponding engraving lines can be designed on the outer pressure ring 7.

[0042] S2. Machine tool pressing: During machine tool pressing, the upper part of the processing device connected to the machine tool moves downward together. The upper die flanging punch 5C contacts the workpiece first. As it continues to move downward, the outer ring of the reinforcing partition to be processed completes the deep drawing and flanging. When the upper die flanging punch 5C contacts the lower die pressing ring 27, the height of the workpiece outer ring is trimmed. During this process, the punch in the upper die plate moves downward and cooperates with the first punch of the lower die to complete the punching of the reinforcing partition process hole. When the upper die punch contacts the second punch of the lower die, the flanging work is completed. As the upper die plate continues to move downward, the upper die punch cooperates with the third punch of the lower die to start the blanking action until the blanking work is completed. As the upper die plate continues to move downward, the reinforcing partition process after blanking is completed by the action of the second punch of the lower die to complete the flanging and trimming.

[0043] S3. After processing is completed, the slide on the machine tool rises to the top dead center, the upper template connected to the machine tool rises with the machine tool, the upper and lower templates of the processing device separate, the processed reinforcing partition is taken out, and the processing waste is automatically removed at the same time.

The die 15 of the working part contacts the workpiece first. When it continues to move downward, the outer ring of the workpiece completes the deep drawing function. When the working part die 15 contacts the working part trimming punch I 38, the outer ring height of the workpiece is trimmed. When the working parts punches I 6, II 7, III 8, and IV 9 continue to descend and contact the workpiece, the inner ring of the workpiece begins the punching action. When the working parts punches I 6, II 7, III 8, and IV 9 contact the lower surface of the workpiece, the punching work ends.

4. The processing apparatus for reinforcing partitions as described in claim 1, characterized in that, The upper support frame and the lower support frame are respectively equipped with guide posts and guide sleeves at the four corners for guiding during the stamping process.

5. A method for processing a reinforced partition, wherein the processing method employs the processing apparatus as described in any one of claims 1 to 4, characterized in that, The processing method includes the following: S1. Fix the connecting parts of the processing device to the machine tool. During the return stroke of the machine tool, the slide on the machine tool rises to the top dead center and rises together with the upper template connected to the machine tool. The upper and lower templates of the processing device are completely separated. Place the reinforcing partition to be processed on the upper end face of the lower template and align it with the position of the required processing hole. S2. Machine tool pressing: During machine tool pressing, the upper part of the processing device connected to the machine tool moves downward together. The upper die flanging punch contacts the workpiece first. As it continues to move downward, the outer ring of the reinforcing partition to be processed completes the deep drawing and flanging. When the upper die flanging punch contacts the lower die pressing ring, the height of the outer ring of the workpiece is trimmed. During this process, the upper die punch in the upper die platen moves downward and cooperates with the first lower die punch to complete the punching of the process hole of the reinforcing partition. When the upper die punch contacts the second lower die punch, the flanging work is completed. As the upper die platen continues to move downward, the upper die punch cooperates with the third lower die punch to start the blanking action until the blanking work is completed. As the upper die platen continues to move downward, the blanked reinforcing partition completes the flanging and trimming under the action of the second lower die punch. S3. After processing is completed, the slide on the machine tool rises to the top dead center, the upper template connected to the machine tool rises with the machine tool, the upper and lower templates of the processing device separate, the processed reinforcing partition is taken out, and the processing waste is automatically removed at the same time.

6. The processing method of a reinforcing partition as described in claim 5, characterized in that, A stripper plate is provided between the upper template and the upper support frame of the processing device. When the machine tool is reset, the stripper plate is pushed to reset. During the reset process, the stripper plate pushes out the die of the upper template to realize the discharge of the punching waste in the die. A top plate is also provided between the lower template and the lower support frame. The top plate is connected to the pressure ring by a long screw. The movement of the top plate can push the pressure ring to move up and down.

7. The processing method for a reinforced partition as described in claim 5, characterized in that, A retaining ring is provided on the upper end face of the inner ring of the third punch of the lower die. The lower end of the retaining ring is connected to a short screw. After the top plate moves upward to a certain stroke, it pushes the short screw upward, thereby realizing the movement of the retaining ring to push out the waste material remaining in the flange punching in the retaining ring.
