Description

Technical Field

[0001] This invention relates to the field of composite skin sheet molding technology, and more particularly to composite skin sheet molding positioning components and multi-station molding equipment and methods. Background Technology

[0002] In the production and processing of composite skin panels, precise positioning of multi-layer panels is required before composite pressing to ensure the structural stability and dimensional accuracy of the finished panels. Currently, related processing equipment often experiences panel position misalignment during panel conveying, leading to inaccurate bonding of multi-layer panels and affecting the subsequent pressing quality. Furthermore, existing equipment often uses a single support structure for its feeding mechanism, making it difficult to adapt to panels of different sizes, and the panels are prone to wobbling during feeding, preventing the orderly stacking of multi-layer panels.

[0003] In the positioning and pressing stage, the traditional positioning components lack flexibility in their fixing structure, and the fit between the pressure plate and the fixing parts is limited. This can easily lead to uneven stress on the sheet metal during pressing, resulting in poor surface flatness of the finished product. Furthermore, the feeding, unloading, and unloading processes in existing multi-station equipment are mostly performed in separate steps, with poor coordination between components, hindering efficient process integration and resulting in low processing efficiency. Simultaneously, the adjustment mechanism has a limited range of adjustment, making it difficult to quickly switch between different workstations according to actual processing needs, thus limiting its applicability and failing to meet diverse production requirements. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing equipment, such as the use of a single support structure in the feeding mechanism, which makes it difficult to adapt to different sizes of plates, the tendency of the plates to shake during the feeding process, the inability to achieve orderly stacking of multiple layers of plates, the lack of flexibility in the fixing structure of traditional positioning components, and the limited precision of the fit between the pressure plate and the fixing parts. The invention proposes a composite skin plate forming positioning component and a multi-station forming equipment and method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A composite skin panel forming and positioning assembly includes a mounting frame II. Four symmetrically arranged fixing rods are fixedly installed inside the mounting frame II. Two parallel fixed rectangular plates are fixedly sleeved on the outer walls of the four fixing rods. Four symmetrically arranged sliding rods are slidably installed inside the mounting frame II. Two parallel pressure plates are fixedly sleeved on the outer walls of the four sliding rods. The pressure plates and fixed rectangular plates are staggered. Two symmetrically arranged T-shaped holes are opened inside the fixed rectangular plates. Four clearance holes are opened inside both the fixed rectangular plates and the pressure plates to allow space for the corresponding fixing rods and sliding rods. A hydraulic rod is fixedly installed on the top of the mounting frame II. The piston rod of the hydraulic rod slides through the mounting frame II and is fixedly installed with a connecting seat. The bottom of the connecting seat is fixedly connected to the pressure plate above.

[0007] The multi-station forming equipment includes the composite skin sheet forming and positioning component as described above, and also includes a frame. Two mounting frames II are fixedly installed on the top of the frame. Two symmetrically arranged mounting frames I are fixedly installed on the top of the frame. The two mounting frames I are located on both sides of the two mounting frames II. The frame is equipped with two sets of conveying components for conveying the sheet material.

[0008] The mounting frame I is equipped with a feeding assembly for feeding sheet metal.

[0009] The top of the frame is fixedly equipped with two symmetrically arranged fixed slide rails. Multiple slide rails III are slidably connected to the top of the two fixed slide rails. Three sliding mounting plates are slidably connected to the top of the multiple slide rails III. The multiple slide rails III are connected to each other by two connecting rods. An adjustment component for adjusting the position of the plate is provided on one side of the sliding mounting plate.

[0010] In one possible design, the conveying assembly includes four symmetrical side guards in pairs. A common drive shaft rotatably passes between two side guards on the same side. Two symmetrically arranged synchronous pulleys are fixedly sleeved on the outer wall of the drive shaft. The outer walls of the two synchronous pulleys on the same side are driven by the same synchronous belt. The synchronous belt is used to convey the plate. A servo motor is fixedly installed inside the frame. A drive sprocket is fixedly installed on the output shaft of the servo motor. A driven sprocket is fixedly installed at one end of the drive shaft. The outer walls of the driven sprocket and the drive sprocket are driven by the same chain.

[0011] In one possible design, the feeding assembly includes an electric push rod I fixedly installed inside the frame, and two parallel trays. Two symmetrically arranged connecting I-plates are fixedly installed on one side of the two trays. The electric push rod I is fixedly installed inside the frame, and the piston rod of the electric push rod I is fixedly connected to the bottom of the tray below.

[0012] In one possible design, the feeding assembly further includes four symmetrically arranged mounting strips. Two symmetrically arranged U-shaped fixing brackets are fixedly installed on one side of two mounting strips located on the same side. Two symmetrically arranged mounting plates I are fixedly installed on one side of each U-shaped fixing bracket. A rectangular mounting plate is fixedly installed on one side of each mounting strip. Two symmetrically arranged slide rails I are fixedly installed on one side of each rectangular mounting plate. The same U-shaped block is slidably connected to one side of each slide rail I. Mounting plates II are fixedly installed at both ends of each U-shaped block. The top and bottom of mounting plates II and I are provided with strip grooves. A sliding support plate II is slidably connected inside the strip groove. A compression spring is provided between one side of the sliding support plate II and one side of the inner wall of the strip groove. Both ends of the compression spring abut against one side of the inner wall of the strip groove and one side of the sliding support plate II through spring seats. An electric push rod II is fixedly installed on the top side of the rectangular mounting plate. The piston rod of the electric push rod II is fixedly connected to the top of the U-shaped block.

[0013] In one possible design, the adjustment assembly includes a fixed mounting block slidably connected to one side of a sliding mounting plate located on both sides. Four symmetrical strip blocks are fixedly connected to one side of the fixed mounting block in pairs. Two symmetrically arranged brackets are fixedly mounted on the top of the strip blocks. An electric push rod IV is fixedly mounted on the top of the sliding mounting plate, and the piston rod of the electric push rod IV is fixedly connected to the top of the fixed mounting block. A rectangular block is fixedly mounted on the bottom of the sliding mounting plate. An electric push rod V is fixedly mounted on one side of the connecting rod, and the piston rod of the electric push rod V is fixedly connected to one side of the rectangular block. An electric push rod III is fixedly mounted on the top of the frame, and the piston rod of the electric push rod III is fixedly connected to one side of one of the slide rails III.

[0014] In one possible design, two symmetrically arranged push plates are fixedly mounted on one side of the sliding mounting plate in the middle.

[0015] A method for forming a composite skin panel, using the multi-station forming equipment described above, includes the following steps:

[0016] S1. The sheet metal is conveyed to the loading station via the conveying assembly;

[0017] S2. The material is lifted by the pallet of the feeding component, and the material is supported and stacked in an orderly manner by the adaptive support unit.

[0018] S3. The stacked boards are transferred to the fixed rectangular plate of the forming and positioning component by adjusting the components;

[0019] S4. Start the hydraulic rod to drive the pressure plate to move down and cooperate with the fixed rectangular plate to press the sheet material evenly.

[0020] S5. After pressing is completed, the molded sheet is removed by adjusting the components.

[0021] In this application, when in use, the sheet material to be composite pressed is conveyed to the middle through the conveying components on both sides. The servo motor can be started, and the output shaft of the servo motor drives the drive sprocket to rotate. The drive sprocket drives the driven sprocket to rotate through the chain. The driven sprocket drives the drive shaft to rotate. The drive shaft drives the synchronous wheel inside the side cover to rotate. The synchronous wheel drives the synchronous belt to convey forward. The synchronous belt conveys the sheet material above forward.

[0022] When the sheet material is conveyed to the top of the pallet, the electric push rod I is activated. The piston rod of the electric push rod I lifts the sheet material upward. At this time, the two ends of the sheet material first contact the arc surfaces of multiple sliding support plates II, which can compress the spring and make the sliding support plates II slide into the groove. When the sheet material moves to the top of the sliding support plates II, the sliding support plates II are pushed by the elastic force of the compression spring. After resetting, they can support the sheet material. The connecting I-plate drives the lower pallet to continue to move the next sheet material upward, and then the two sheets material are placed on the top of the upper and lower sets of sliding support plates II.

[0023] At this point, the corresponding electric push rod V can be activated. The output shaft of electric push rod V drives the rectangular block to move laterally. The rectangular block drives the sliding mounting plate to move laterally. The sliding mounting plate drives the fixed mounting block to move laterally. The fixed mounting block drives the strip block and the bracket to move laterally. At this point, electric push rod II can be activated. The piston rod of electric push rod II drives the U-shaped block to move upward. The U-shaped block drives the mounting plates II on both sides to move upward. The mounting plates II drive the two sliding support plates II to move upward. At this point, the sliding support plates II move the two plates upward, slightly away from the bracket. At this point, the strip block and the bracket are inserted into the gap.

[0024] Re-activate electric push rod IV. The piston rod of electric push rod IV drives the fixed mounting block to move upward. The fixed mounting block drives the bracket and strip block to move upward, thus lifting the plate. Re-activate electric push rod V. The piston rod of electric push rod V retracts, allowing the plate to be removed. At the same time, the bracket and strip block on the other side send the lifted plate into the corresponding fixed rectangular plate. At this time, the bracket and strip block move downward and out of the T-hole, thus placing the plate on top of the fixed rectangular plate, completing the feeding process.

[0025] Furthermore, the central push plate can push out the pressed and shaped sheet material, thereby realizing the material discharge process. Simultaneously, the electric push rod III can be started. The output shaft of the electric push rod III drives the slide rail III to move laterally, and the slide rail III drives the connecting rod to move laterally, thereby adjusting the position of the three sliding mounting plates, changing the feeding, picking and discharging positions, and thus improving work efficiency.

[0026] Once the sheet material is placed, the hydraulic rod can be activated. The piston rod of the hydraulic rod moves the connecting seat downward, and the connecting seat moves the pressure plate downward. Since the two pressure plates are fixedly connected by multiple sliding rods, the sliding rods can move the pressure plate below downward synchronously. At this time, the pressure plate will press the sheet material at the top of the fixed rectangular plate, completing the pressing process.

[0027] Beneficial effects: By setting up a molding and positioning assembly consisting of mounting bracket II, fixed rods, fixed rectangular plates, sliding rods, pressure plates, hydraulic rods, and connecting seats, the four fixed rods provide stable support for the two fixed rectangular plates, the four sliding rods ensure that the two pressure plates can slide smoothly, and when the hydraulic rods drive the pressure plates to move down through the connecting seats, the staggered arrangement of the pressure plates and fixed rectangular plates can form uniform pressing on the plates, effectively improving the structural compactness of the composite plates. At the same time, the setting of the clearance holes avoids the interference of the fixed rods and sliding rods on the pressing process, ensuring the accuracy of positioning and pressing.

[0028] In the multi-station forming equipment, two sets of conveying components drive synchronous pulleys via drive shafts. These pulleys, in turn, drive synchronous belts to achieve stable conveying of the sheet metal. Compared to traditional conveying methods, this reduces positional shifts during sheet metal transport, providing a better foundation for subsequent processing. The feeding component inside mounting frame I uses an electric push rod I to lift and lower the pallet, working in conjunction with connecting I-beams to achieve orderly stacking of multiple layers of sheet metal. The installation of strip rods, U-shaped fixing frames, slide rail I, U-shaped blocks, mounting plate II, sliding support plate II, and compression springs allows the sliding support plate II to adaptively adjust according to the sheet metal dimensions. The compression springs provide flexible support for the sheet metal, preventing shaking or damage during feeding and adapting to the feeding requirements of different sheet metal specifications.

[0029] The adjustment assembly uses electric push rod V to move the rectangular block and sliding mounting plate laterally, while electric push rod IV drives the fixed mounting block, strip block, and bracket to move up and down, achieving precise lifting and transfer of the sheet material. The bracket and strip block can smoothly insert into the gaps between the sheet materials and move out through the T-holes, ensuring that the sheet material is stably placed on the fixed rectangular plate, completing efficient feeding. The central push plate can directly push out the pressed sheet material, achieving rapid discharge. Electric push rod III can drive the slide rail III and connecting rod to move laterally, adjusting the position of the three sliding mounting plates, allowing the feeding, picking, and discharging processes to be switched synchronously, significantly improving processing efficiency.

[0030] Through the coordinated operation of its components, the entire equipment achieves integrated operation of sheet material conveying, feeding, positioning, pressing and discharging. The smooth connection between each process not only reduces manual intervention and lowers the difficulty of operation, but also effectively ensures the positioning accuracy and composite pressing quality of multi-layer sheets, broadens the scope of application of the equipment, and meets the mass production needs of composite skin sheets of different specifications.

Detailed Implementation

[0040] 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.

[0041] In one embodiment: Refer to Figure 1-8 The forming equipment, the frame 1, is the basic support component of the multi-station forming equipment. It is made of high-strength steel to ensure the overall structural stability. Two symmetrically distributed mounting frames II 4 are fixedly installed on its top. Two mounting frames I 3 are fixed on the top of the frame 1 and located on both sides of the two mounting frames II 4. Two sets of conveying components are set inside the frame 1 to realize the directional conveying of the sheet metal. The conveying assembly includes four symmetrical side covers 2. The two side covers 2 on the same side rotate through the same drive shaft 11. The drive shaft 11 is made of alloy steel, and two symmetrical synchronous pulleys are fixedly fitted on its outer wall. The outer walls of the two synchronous pulleys on the same side are driven by the same synchronous belt 12. A servo motor 13 is fixedly installed inside the frame 1. The output shaft of the servo motor 13 is fixedly fitted with a drive sprocket 16. A driven sprocket 14 is fixedly installed at one end of the drive shaft 11. The outer walls of the driven sprocket 14 and the drive sprocket 16 are driven by the same chain 15. After the servo motor 13 is started, the output shaft of the servo motor 13 drives the drive sprocket 16 to rotate. The drive sprocket 16 drives the driven sprocket 14 to rotate through the chain 15. The driven sprocket 14 drives the drive shaft 11 to rotate. The drive shaft 11 drives the synchronous pulleys inside the side covers 2 to rotate. The synchronous pulleys drive the synchronous belt 12 to move forward, thereby smoothly conveying the plate placed above the synchronous belt 12 to the designated position and reducing positional deviation during the conveying process.

[0042] The feeding assembly inside the mounting frame I3 includes an electric push rod I8 fixedly installed inside the frame 1, and two parallel pallets 10. Two symmetrical connecting I-plates 18 are fixedly installed on one side of each pallet 10. The connecting I-plates 18 and pallets 10 are fixedly connected by bolts. The piston rod of the electric push rod I8 is fixedly connected to the bottom of the lower pallet 10, allowing the pallet 10 to move up and down. The feeding assembly also includes four symmetrical mounting strips 28. Two symmetrical U-shaped fixing frames 17 are fixedly installed on one side of two mounting strips 28 on the same side. Two symmetrical mounting plates I20 are fixedly installed on one side of the U-shaped fixing frames 17. A rectangular mounting plate 29 is fixedly installed on one side of each mounting strip 28. Two symmetrical slide rails I23 are fixedly installed on one side of each rectangular mounting plate 29. A U-shaped block 24 is slidably connected to one side of each slide rail I23. Mounting plates II27 are fixedly installed at both ends of the U-shaped block 24. Both the top and bottom of the mounting plate I20 and the mounting plate II27 are provided with strip grooves 26. A sliding support plate II25 is slidably connected inside the strip groove 26. A compression spring 22 is provided between one side of the sliding support plate II25 and one side of the inner wall of the strip groove 26. Both ends of the compression spring 22 are in contact with one side of the inner wall of the strip groove 26 and one side of the sliding support plate II25 through spring seats. An electric push rod II19 is fixedly installed on one side of the top of the rectangular mounting plate 29. The piston rod of the electric push rod II19 is fixedly connected to the top of the U-shaped block 24. When the sheet material is conveyed to the pallet 10 via the conveying assembly, the electric push rod I8 is activated. Its piston rod pushes the pallet 10 upward to lift the sheet material. The two ends of the sheet material first contact the arc surfaces of multiple sliding support plates II25, which then compress the spring 22, causing the sliding support plates II25 to slide into the groove 26. When the sheet material moves above the sliding support plates II25, the sliding support plates II25 return to their original position under the elastic force of the spring 22, providing stable support for the sheet material. The connecting I-beam plate 18 drives the lower pallet 10 to continue moving upward, transporting the next sheet material to the corresponding position. Finally, two sheets material are stacked in an orderly manner on top of the upper and lower sets of sliding support plates II25, which can accommodate sheets of different sizes while avoiding shaking and damage during the loading process.

[0043] Two symmetrical fixed slide rails 7 are fixedly installed on the top of the frame 1. Multiple slide rails III 45 are slidably connected to the top of the fixed slide rails 7. Each fixed slide rail 7 is covered with a telescopic dust cover, and the two ends of the dust cover are fixedly connected to the slide rail III 45 and the frame 1 respectively. The multiple slide rails III 45 are interconnected by two connecting rods 38. The connecting rods 38 are fixed to the slide rails III 45 by welding to ensure synchronous movement and that the dust cover does not interfere with the transmission. The adjustment component set on one side of the sliding mounting plate 6 includes a fixed mounting block 42 slidably connected to one side of the two sliding mounting plates 6. Four symmetrical strip blocks 44 are fixedly connected to one side of the fixed mounting block 42. Two symmetrical brackets 43 are fixedly installed on the top of the strip blocks 44. The strip blocks 44 and the brackets 43 are integrally molded, and the structure is stable. An electric push rod IV 40 is fixedly installed on the top of the sliding mounting plate 6. The piston rod of the electric push rod IV 40 is fixedly connected to the top of the fixed mounting block 42, which can drive the fixed mounting block 42 to move up and down. A rectangular block 41 is fixedly installed on the bottom of the sliding mounting plate 6. An electric push rod V 37 is fixedly installed on one side of the connecting rod 38. The piston rod of the electric push rod V 37 is fixedly connected to one side of the rectangular block 41, which can drive the sliding mounting plate 6 to move laterally. An electric push rod III 36 is fixedly installed on the top of the frame 1. Its piston rod is fixedly connected to one side of one of the slide rails III 45. Start the electric push rod V37, whose output shaft drives the rectangular block 41 to move laterally, which in turn drives the fixed mounting block 42, strip block 44 and bracket 43 to move laterally synchronously through the sliding mounting plate 6. At the same time, start the electric push rod II19, whose piston rod drives the U-shaped block 24 to move upward along the slide rail I23. The U-shaped block 24 drives the two mounting plates II27 to move upward. The mounting plates II27 drive the sliding support plate II25 to move upward, slightly lifting the two plates and separating them from the support plate 10. At this time, the strip block 44 and bracket 43 are inserted into the gap between the plates and the support plate 10. Then, the electric push rod IV40 is activated, and its piston rod drives the fixed mounting block 42 to move upward. The plate is lifted by the strip block 44 and the bracket 43. The electric push rod V37 is activated again to retract its piston rod, which moves the plate out of the feeding area. The bracket 43 and the strip block 44 on the other side transport the lifted plate to the top of the corresponding fixed rectangular plate 30. Then, the bracket 43 and the strip block 44 move downward and move out from the T-hole 35. The plate is placed stably on the top of the fixed rectangular plate 30, completing the feeding process.

[0044] Two symmetrical push plates 39 are fixedly installed on one side of the central sliding mounting plate 6. The push plates 39 are made of wear-resistant material. After the sheet material is pressed, the push plates 39 can push the pressed sheet material out of the forming area to achieve rapid material discharge. Activating the electric push rod Ⅲ 36 causes its output shaft to drive the slide rail Ⅲ 45 to move laterally along the fixed slide rail 7. The slide rail Ⅲ 45, through the connecting rod 38, drives all slide rails Ⅲ 45 to move synchronously, thereby adjusting the position of the three sliding mounting plates 6. This enables rapid switching between feeding, picking, and discharging stations, improving overall work efficiency.

[0045] This application can be used in the field of composite skin sheet molding, and can also be used in other fields applicable to this application.

[0046] In another embodiment: Reference Figure 1-8 This invention relates to a composite skin panel forming and positioning component, a multi-station forming equipment and method, which is applied in the field of composite skin panel forming. The structure of this embodiment is basically the same as that of the aforementioned embodiment, except that: four symmetrical fixed rods 31 are fixedly installed inside the mounting frame II4 of the composite skin panel forming and positioning component. The fixed rods 31 are made of high-strength alloy material. Two parallel fixed rectangular plates 30 are fixedly sleeved on the outer wall of the four fixed rods 31. Four symmetrical sliding rods 33 are slidably installed inside the mounting frame II4. Two parallel pressure plates 9 are fixedly sleeved on the outer wall of the four sliding rods 33. The pressure plates 9 and the fixed rectangular plates 30 are staggered. Two symmetrical T-shaped holes 35 are opened inside the fixed rectangular plates 30. Four clearance holes 34 are opened inside the fixed rectangular plates 30 and the pressure plates 9 to provide movement space for the corresponding fixed rods 31 and sliding rods 33 and avoid movement interference. The top of the mounting bracket II4 is fixedly installed with a hydraulic rod 5. The hydraulic rod 5 adopts a well-sealed structural design. Its piston rod slides through the mounting bracket II4 and is fixedly installed with a connecting seat 32. The bottom of the connecting seat 32 is fixedly connected to the pressure plate 9 above. After the sheet material is placed on top of the fixed rectangular plate 30, the hydraulic rod 5 is activated, and its piston rod pushes the connecting seat 32 downward. The connecting seat 32 drives the upper pressure plate 9 to move downward synchronously. Since the two pressure plates 9 are fixedly connected by multiple sliding rods 33, when the upper pressure plate 9 moves downward, it drives the lower pressure plate 9 to move downward synchronously and smoothly through the sliding rods 33. The staggered arrangement of the pressure plates 9 and the fixed rectangular plate 30 makes the sheet material subject to uniform pressure, realizing the precise composite pressing of multi-layer sheet materials, improving the structural compactness and surface flatness of the finished sheet material. A PLC controller is fixedly installed inside the frame 1. The PLC controller is electrically connected to the servo motor 13, electric push rod I 8, electric push rod II 19, electric push rod III 36, electric push rod IV 40, electric push rod V 37 and hydraulic rod 5 respectively. Through the preset program, the actuators are controlled to start and stop in sequence, realizing the coordinated linkage of conveying, feeding, transferring, pressing and discharging processes.

[0047] However, as is well known to those skilled in the art, the working principles and wiring methods of servo motor 13, electric linear actuator I 8, electric linear actuator II 19, electric linear actuator V 37, electric linear actuator IV 40, and electric linear actuator III 36 are all conventional methods or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0048] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
