Description

Technical Field

[0001] This invention relates to the field of processing equipment technology, and in particular to an I-shaped straight stringer stamping device and its stamping method. Background Technology

[0002] The stringer is an important load-bearing component in the aircraft structure. According to its location, it can be divided into two main categories: fuselage stringers and wing stringers. The stringer is usually made of high-toughness 5055 aluminum alloy. It has the characteristics of small deflection and variable cross section "I". There are two traditional manufacturing methods. One is to directly machine the stringer part with small deflection on the blank by CNC machining. The other manufacturing method is to first CNC mill the straight stringer part on the blank, and then use a three-point bending process to manually bend the straight stringer to the required shape with the help of a press.

[0003] Some long honing processes require multi-stage bending operations. When using the current three-point bending processing method, the bent long honing will affect the conveying process. Therefore, the long honing needs to be manually moved after stamping so that the bent section can meet the requirements of roller clamping and conveying. This leads to a decrease in processing efficiency and an increase in workload. Summary of the Invention

[0004] This invention discloses a stamping device and stamping method for a straight long stringer of I-beam type, aiming to solve the technical problem in the background art that requires manual movement of the long stringer after stamping so that the curved section can meet the requirements of roller clamping and conveying, which leads to a decrease in processing efficiency and an increase in labor intensity.

[0005] This invention proposes a straight long stringer stamping device, comprising an operating platform and a long stringer body. A side platform and a fixed platform are fixedly connected to the upper side of the operating platform, and the side platform and fixed platform are located on opposite sides of the long stringer body. A stamping device is arranged on the upper side of the side platform, and an auxiliary component is arranged above the fixed platform. Two symmetrical sliding tables are arranged on the lower side of the auxiliary component, and two symmetrical sliding grooves are opened on the upper side of the fixed platform. The two sliding tables are movably connected within the two sliding grooves. Two symmetrical tailstocks are arranged on the side of the fixed platform away from the long stringer body. Each tailstock has an installation groove, and a first hydraulic cylinder is fixedly connected inside each installation groove. The output end of the first hydraulic cylinder is fixedly connected to the sliding table on the same side.

[0006] The system comprises an operating table, a honing body, a side table, a fixed table, a stamping device, auxiliary components, a slide table, a tailstock, and a first hydraulic cylinder. A horizontal three-point bending technique is used to achieve cold bending of the honing body. Movable auxiliary components provide support (two points) on the back of the honing body during stamping. After stamping, they reset sequentially along with the stamping device, preventing the honing body from forming an arc after stamping. The two points on the back limit the honing body's movement, thus improving its conveying efficiency and enabling continuous conveying of the honing body during multi-position stamping operations.

[0007] In a preferred embodiment, the stamping equipment includes a ball screw and a servo motor. The ball screw is fixedly connected to the upper side of a side platform. A back plate is fixedly connected to the side of the side platform away from the honing body. One end of the ball screw is fixedly connected to the outer wall of the back plate. An installation head is provided at the front end of the ball screw. A helical gear is fixedly connected to the end of the ball screw through the back plate. An installation groove is provided on the lower side of the side platform. The servo motor is fixedly connected to the inner wall of the installation groove. The output end of the servo motor is connected to a short shaft through a coupling. The other end of the short shaft is fixedly connected to a drive gear through the back plate. The drive gear and the helical gear mesh through tooth grooves.

[0008] In a preferred embodiment, a punch seat is fixedly connected to the front end of the mounting head, a punch head is provided at the top of the punch seat, and a side support assembly is provided on the punch seat; the side support assembly includes a movable support frame and a second hydraulic cylinder, a recessed hole is provided on the punch seat, the movable support frame is movably connected inside the recessed hole, two symmetrical grooves are provided on the side of the movable support frame near the punch head, and side support protrusions are movably connected inside the two grooves, the two side support protrusions are symmetrically distributed on both sides of the punch head, a push frame is provided on the side of the movable support frame away from the punch head, and two side support protrusions are fixedly connected on the side of the push frame near the movable support frame. A symmetrical push plate has two symmetrical sliding holes on the movable support. The other ends of the two push plates pass through the two sliding holes and are movably connected to the side support protrusions. An L-shaped connecting frame is fixedly connected to the side of the movable support near the push frame. A reverse motor is fixedly connected to the L-shaped connecting frame. The output end of the reverse motor is connected to a second lead screw through a coupling. A threaded groove is opened on the push frame. The other end of the second lead screw passes through the threaded hole on the push frame and is movably connected to the movable support. A second hydraulic cylinder is fixedly connected to the inner wall of the concave hole of the punch seat. The output end of the second hydraulic cylinder is fixedly connected to the L-shaped connecting frame.

[0009] By incorporating a side support assembly, which utilizes two adjustable side support protrusions, the long honing body can be supported at different bending curvatures. This prevents localized deformation of the long honing body after being subjected to pressure at a single point, thus avoiding failure to meet the preset bending curvature requirements and improving the stamping effect of the long honing body. The side support assembly can be adjusted according to the actual stamping curvature requirements of the long honing body, thereby expanding the applicability of the device.

[0010] In a preferred embodiment, the auxiliary component includes a shift box and two slide blocks. The lower side of the shift box is fixedly connected to the two slide blocks. A rectangular recess is formed on the side of the shift box near the honing body. A sliding groove is provided inside the rectangular recess. The two slide blocks are movably connected inside the rectangular recess. An inner support block is fixedly connected to the side of each slide block near the honing body. Symmetrical outer support rings are fixedly connected to the upper and lower sides of the inner support block. Both slide blocks have threaded holes with opposite thread directions. The shift box has a rotating shaft inside. One end of the rotating shaft is movably connected to the inner wall of the rectangular concave hole of the shift box, and the other end of the rotating shaft passes through the other side of the shift box and is fixedly connected to a driving gear. The rotating shaft has two symmetrical first lead screws. The two ends of the first lead screws are respectively connected to the threaded holes of the two slides through the inner wall threads. An adjusting motor is fixedly connected to the outside of the shift box. The output end of the adjusting motor is connected to a short shaft through a coupling. The other end of the short shaft is fixedly connected to a drive gear. The drive gear and the driving gear are meshed through tooth grooves.

[0011] By incorporating an auxiliary component that is positioned opposite the stamping equipment during the stamping process, supporting the long honing body on the other side and forming a three-point support with the punch of the stamping equipment, the auxiliary component can be adjusted according to the length of the stamping section of the long honing body to meet the stamping arc requirements of different lengths, thus improving the applicability of the device.

[0012] In a preferred embodiment, a front side plate is fixedly connected to one side of the operating platform, and a support is fixedly connected above the front side plate. Two symmetrically arranged conveyor rollers are arranged on the upper side of the support, and the long honing body is located between the two conveyor rollers. A rear side plate is fixedly connected to the other side of the operating platform, a base frame is fixedly connected above the rear side plate, a top frame is fixedly connected to the upper side of the base frame, and two symmetrical short rods are fixedly connected between the top frame and the base frame. Movable rollers are movably connected to the outside of each of the two short rods. A shaft is provided between the top frame and the base frame. The shaft is externally fixedly connected to two transverse wheels, which are symmetrically distributed on the upper and lower sides of the honing body. Each of the two transverse wheels has a rubber layer on its opposite side. The base frame is fixedly connected to two symmetrical convex support plates on the side closest to the honing body. Each of the two convex support plates has a sliding groove on its upper side. Each of the two sliding grooves is movably connected to a Z-shaped bracket. Each of the Z-shaped brackets has a limit roller at its top and a limit spring fixedly connected to its lower end. The other end of the limit spring is fixedly connected to the inner wall of the sliding groove of the convex support plate on the same side.

[0013] Equipped with conveyor rollers, transverse wheels, movable rollers, Z-shaped supports, limit pressure rollers, and limit springs, the long honing body is placed above the support during the stamping operation. The front end of the long honing body is positioned between two conveyor rollers, and the other end is positioned between two transverse wheels. The two conveyor rollers are driven by a drive device inside the support to rotate relative to each other, while the two transverse wheels rotate synchronously clockwise under the drive device inside the base frame, continuously conveying the long honing body. When the bent section after stamping reaches the position of the transverse wheels, the Z-shaped support is subjected to force away from the movable rollers, and the limit springs are stretched and undergo elastic deformation. Therefore, the long honing body is always subjected to the reverse force of the limit springs during the transverse wheel conveying process, causing the long honing body to be conveyed in close contact with the movable rollers.

[0014] A method for stamping an I-shaped straight stringer, using an I-shaped straight stringer stamping device as described above, includes the following steps:

[0015] Step 1: Before the stamping operation, adjust the auxiliary components and side support components according to the stamping curvature requirements of the honing body, put in the honing body for trial use and perform the stamping operation, check whether the curvature after stamping reaches the preset value, then set the stamping position of the honing body, and reset the auxiliary components and stamping equipment to be ready for operation.

[0016] Step 2: Place the long honing body above the support, with the front end of the long honing body between two conveying rollers and the other end between two transverse rollers, and the long honing body is continuously conveyed;

[0017] Step 3: During continuous conveying, when the first preset stamping position of the honing body reaches the front of the stamping equipment, the honing body stops conveying, the auxiliary components enter the preset position, the stamping equipment performs a stamping operation on the honing body, the honing body is bent by the stamping to form a preset arc, and then the stamping equipment and auxiliary components are reset.

[0018] Step 4: The honing body is conveyed again, and the second preset stamping position of the honing body arrives in front of the stamping equipment. Repeat the operation of Step 3.

[0019] Step 5: Perform the same operations as described above to complete the stamping of multiple parts of the honing body.

[0020] As can be seen from the above, the straight stringer stamping device provided by the present invention uses horizontal three-point bending technology to achieve cold bending forming of the stringer body. The movable auxiliary component can support the back of the stringer body (two support points) during the stamping operation. After the stamping is completed, it will be reset along with the stamping equipment to avoid the stringer body from forming an arc after stamping. The two support points on the back limit the stringer body and affect the conveying of the stringer body. This realizes the continuous conveying of the stringer body in multi-position stamping operation and improves the multi-position stamping processing efficiency of the stringer body.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] The I-beam straight stringer stamping device disclosed in this invention is mainly used in scenarios where processing efficiency decreases and workload increases.

[0032] Reference Figures 1-8 A straight long stringer stamping device includes an operating platform 1 and a long stringer body 2. A side platform 3 and a fixed platform 4 are bolted to the upper side of the operating platform 1, and the side platform 3 and the fixed platform 4 are located on both sides of the long stringer body 2. A stamping device 5 is provided on the upper side of the side platform 3, and an auxiliary component 6 is provided above the fixed platform 4. Two symmetrical slides 7 are provided on the lower side of the auxiliary component 6, and two symmetrical sliding grooves are opened on the upper side of the fixed platform 4. The two slides 7 are slidably connected inside the two sliding grooves. Two symmetrical tailstocks 8 are provided on the side of the fixed platform 4 away from the long stringer body 2. Each tailstock 8 has an installation groove. A first hydraulic cylinder 9 is bolted to the inside of each installation groove, and the output end of the first hydraulic cylinder 9 is bolted to the slide 7 on the same side.

[0033] Specifically, during the stamping operation, the first hydraulic cylinder 9 extends and pushes the slide table 7 towards the honing body 2. The auxiliary component 6 moves towards the honing body 2 to a preset position. The stamping equipment 5 drives the honing body 2 to perform a stamping operation to form a specific arc. Subsequently, the stamping equipment 5 and the auxiliary component 6 are reset one after another, and the honing body 2 is transported again until it reaches the front of the stamping equipment 5 again at the preset stamping position. The device adopts a horizontal three-point bending technology to realize the cold bending forming of the honing body. The movable auxiliary component 6 can support the back of the honing body 2 (two support points) during the stamping operation. After the stamping is completed, it is reset one after another along with the stamping equipment 5 to prevent the honing body 2 from forming an arc after stamping. The two support points on the back limit the honing body 2 and affect the transport of the honing body 2, so as to realize the continuous transport of the honing body 2 in multi-position stamping operation and improve the multi-position stamping processing efficiency of the honing body 2.

[0034] Reference Figure 1 and Figure 3The stamping equipment 5 includes a ball screw 501 and a servo motor 502. The ball screw 501 is bolted to the upper side of the side platform 3. A back plate 503 is bolted to the side of the side platform 3 away from the honing body 2. One end of the ball screw 501 is bolted to the outer wall of the back plate 503. An installation head 504 is provided at the front end of the ball screw 501. A helical tooth 505 is bolted through the back plate 503 at the end of the ball screw 501. An installation groove is provided on the lower side of the side platform 3. The servo motor 502 is bolted to the inner wall of the installation groove. A short shaft is connected to the output end of the servo motor 502 through a coupling. The other end of the short shaft is bolted through the back plate 503 to a drive gear 506. The drive gear 506 and the helical tooth 505 mesh through tooth grooves.

[0035] Specifically, after the servo motor 502 starts, it drives the drive gear 506 to rotate. The drive gear 506 meshes with the helical gear 505, and the ball screw 501 is driven, converting the rotary motion into linear motion to realize the stamping operation.

[0036] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 The front end of the mounting head 504 is bolted to a punch seat 10, the top of the punch seat 10 is provided with a punch 11, and a side support assembly 12 is provided on the punch seat 10; the side support assembly 12 includes a movable support frame 1201 and a second hydraulic cylinder 1202. The punch seat 10 has a recessed hole, and the movable support frame 1201 is slidably connected inside the recessed hole. Two symmetrical grooves are provided on the side of the movable support frame 1201 near the punch 11. The inside of each of the two grooves is rotatably connected to a side support protrusion 1203 through a bearing. The two side support protrusions 1203 are symmetrically distributed on both sides of the punch 11. A pusher 1204 is provided on the side of the movable support frame 1201 away from the punch 11. Two symmetrical push plates 1205 are bolted to the side of the pusher 1204 near the movable support frame 1201. Two symmetrical sliding holes are provided on the 201. The other ends of the two push plates 1205 pass through the two sliding holes and are rotatably connected to the side support protrusion 1203 through bearings. An L-shaped connecting frame 1206 is bolted to the side of the movable support 1201 near the push frame 1204. A reverse motor 1207 is bolted to the L-shaped connecting frame 1206. The output end of the reverse motor 1207 is connected to the second lead screw 1208 through a coupling. A threaded groove is provided on the push frame 1204. The other end of the second lead screw 1208 passes through the threaded hole on the push frame 1204 and is rotatably connected to the movable support 1201 through bearings. The second hydraulic cylinder 1202 is bolted to the inner wall of the concave hole of the punch seat 10. The output end of the second hydraulic cylinder 1202 is bolted to the L-shaped connecting frame 1206.

[0037] Specifically, the ball screw 501 extends forward, driving the punch seat 10 to move forward. The punch 11 contacts and presses against the honing body 2, causing the honing body 2 to bend under force and form an arc. The side support assembly 12 provides limiting support to the honing body 2 during the bending process, so that the arc reaches the preset value. The side support assembly 12 is adjusted as follows: according to the stamping arc requirement, the second hydraulic cylinder 1202 is first adjusted. When the stamping arc is large, the second hydraulic cylinder 1202 extends; conversely, the second hydraulic cylinder 1202 retracts. Then, the reverse motor 1207 is started to rotate, driving the second screw 1208 to rotate. The position of the pusher 1204 is adjusted so that the side support protrusions 1203 deflect. When the pusher 1204 moves forward, the two side support protrusions 1203 deflect toward the punch 11; conversely, they deflect away from the punch 11.

[0038] In specific application scenarios, the side support assembly 12 is suitable for supporting the bending curvature of the honing body 2 during the stamping process. That is, the side support assembly 12 uses two adjustable side support protrusions 1203 to meet the support of different bending curvatures of the honing body 2, avoiding local deformation of the honing body 2 after being pressed at a single point, thus failing to meet the preset bending curvature requirements and improving the stamping effect of the honing body 2. The side support assembly 12 can be adjusted according to the actual stamping curvature requirements of the honing body 2, thereby improving the applicability of the device.

[0039] Reference Figure 1 , Figure 5 and Figure 7 The auxiliary component 6 includes a shift box 601 and two slide blocks 602. The lower side of the shift box 601 is bolted to the two slides 7. A rectangular recess is provided on the side of the shift box 601 near the long honing body 2. A sliding groove is provided inside the rectangular recess. The two slide blocks 602 are slidably connected inside the rectangular recess. An inner support block 603 is bolted to the side of each slide block 602 near the long honing body 2. Symmetrical outer support rings 604 are bolted to the upper and lower sides of the inner support block 603. Both slide blocks 602 have threaded holes with opposite thread directions. A rotating shaft 6 is provided inside the shift box 601. 05. One end of the rotating shaft 605 is rotatably connected to the inner wall of the rectangular concave hole of the shift box 601 via a bearing. The other end of the rotating shaft 605 passes through the other side of the shift box 601 and is connected to the driving gear 607 via bolts. Two symmetrical first lead screws 606 are provided on the rotating shaft 605. The two ends of the first lead screws 606 are rotatably connected to the threaded holes of the two slides 602 via the inner wall threads. An adjusting motor 608 is bolted to the outside of the shift box 601. The output end of the adjusting motor 608 is connected to a short shaft via a coupling. The other end of the short shaft is bolted to a drive gear 609. The drive gear 609 and the driving gear 607 are meshed through tooth grooves.

[0040] Specifically, during the stamping operation, the inner support block 603 and the outer support ring 604 on the auxiliary component 6 support the narrow wall and the wide wall of the long honing body 2 respectively (the cross section of the long honing body 2 is "I" shaped, divided into a narrow wall and a wide wall), forming two support points; the auxiliary component 6 is adjusted: the position of the two slide blocks 602 is adjusted according to the length of the stamping section of the long honing body 2, that is, the adjustment motor 608 drives the drive gear 609 to mesh with the traction gear 607, the first lead screw rotates, and the two slide blocks 602 slide towards or in opposite directions in the shift box 601;

[0041] In specific application scenarios, the auxiliary component 6 is suitable for providing two-point support for the honing body 2 during the stamping process. That is, the auxiliary component 6 is located on the opposite side of the stamping equipment 5 during the stamping process, supporting the honing body 2 on the other side, forming a three-point support with the punch 11 of the stamping equipment 5. The auxiliary component 6 can be adjusted according to the stamping section length of the honing body 2 to meet the stamping arc requirements of different lengths, thus improving the applicability of the device.

[0042] Reference Figure 1 , Figure 4 , Figure 5 and Figure 8 One side of the operating platform 1 is bolted to a front side plate 13, and a support 14 is bolted to the top of the front side plate 13. Two symmetrically arranged conveyor rollers 15 are mounted on the upper side of the support 14, and the long honing body 2 is located between the two conveyor rollers 15. The other side of the operating platform 1 is bolted to a rear side plate 16, and a base frame 17 is bolted to the top of the rear side plate 16. A top frame 18 is bolted to the upper side of the base frame 17, and two symmetrical short rods are bolted between the top frame 18 and the base frame 17. Each of the two short rods is rotatably connected to a movable roller 22 via bearings. A shaft 19 is positioned between the top frame 18 and the base frame 17. Two transverse wheels 20 are bolted to the outside of the rod 19. The two transverse wheels 20 are symmetrically distributed on the upper and lower sides of the long honing body 2. A rubber layer 21 is provided on the opposite side of the two transverse wheels 20. Two symmetrical protruding support plates 23 are bolted to the side of the base frame 17 near the long honing body 2. A sliding groove is opened on the upper side of the two protruding support plates 23. A Z-shaped bracket 24 is slidably connected inside the two sliding grooves. A limit pressure roller 25 is provided at the top of the Z-shaped bracket 24. A limit spring 26 is bolted to the lower end of the Z-shaped bracket 24. The other end of the limit spring 26 is bolted to the inner wall of the sliding groove of the protruding support plate 23 on the same side.

[0043] Specifically, during the stamping operation, the long honing body 2 is placed above the support 14, with the front end of the long honing body 2 positioned between two conveying rollers 15 and the other end positioned between two transverse wheels 20. The two conveying rollers 15 are driven by the drive device inside the support 14 to rotate relative to each other, and the two transverse wheels 20 are driven by the drive device inside the base frame 17 to rotate synchronously clockwise, and the long honing body 2 is continuously conveyed. When the bent section after stamping reaches the position of the transverse wheel 20, the Z-shaped bracket 24 is subjected to force away from the direction of the movable roller 22, and the limiting spring 26 is stretched and undergoes elastic deformation. Therefore, the long honing body 2 is always subjected to the reverse force of the limiting spring 26 during the conveying process of the transverse wheel 20, which causes the long honing body 2 to be closely conveyed with the movable roller 22.

[0044] A method for stamping an I-shaped straight stringer, using an I-shaped straight stringer stamping device as described above, includes the following steps:

[0045] Step 1: Before the stamping operation, adjust the auxiliary component 6 (adjust the position of the two slide blocks 602 according to the stamping section length of the long honing body 2, that is, adjust the motor 608 to drive the drive gear 609 to mesh with the pull gear 607, the first lead screw rotates, and the two slide blocks 602 slide towards or in opposite directions in the shift box 601) and the side support component 12 (adjust the second hydraulic cylinder 1202 first according to the stamping arc requirement; when the stamping arc is large, the second hydraulic cylinder 1202 extends, and vice versa) according to the stamping arc requirement. The pressure cylinder 1202 retracts, and the reverse motor 1207 is started to rotate, driving the second lead screw 1208 to rotate. The position of the pusher 1204 is adjusted so that the side support protrusions 1203 deflect. When the pusher 1204 moves forward, the two side support protrusions 1203 deflect towards the punch 11, and vice versa. The long honing body 2 is placed in for testing and stamping operation is performed. The arc after stamping is checked to see if it reaches the preset value. Then the stamping position of the long honing body 2 is set, and the auxiliary component 6 and the stamping equipment 5 are reset to be ready for operation.

[0046] Step 2: Place the long honing body 2 above the support 14. The front end of the long honing body 2 is between two conveying rollers 15, and the other end is between two transverse wheels 20. The long honing body 2 is continuously conveyed.

[0047] Step 3: During continuous conveying, when the first preset stamping position of the honing body 2 reaches the front of the stamping equipment 5, the honing body 2 stops conveying, the auxiliary component 6 enters the preset position, and the stamping equipment 5 performs a stamping operation on the honing body 2 (after the servo motor 502 starts, it drives the drive gear 506 to rotate, the drive gear 506 meshes with the helical gear 505, the ball screw 501 is driven, converting the rotational motion into linear motion, the ball screw 501 extends forward to drive the punch seat 10 to move forward, the punch 11 contacts and squeezes the honing body 2, the honing body 2 bends under force to form an arc, the side support component 12 limits and supports the honing body 2 during the bending process, so that the arc reaches the preset value), the honing body 2 is stamped and bends to form a preset arc, and then the stamping equipment 5 and the auxiliary component 6 are reset;

[0048] Step 4: The honing body 2 is conveyed again, and the second preset stamping position of the honing body 2 arrives in front of the stamping equipment 5. Repeat the operation of step 3.

[0049] Step 5: Perform the same operation as above to complete the stamping of multiple parts of the honing body 2.
