Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, specifically to a special mold for processing integrated stiffeners in ships and its usage method. Through mold structure innovation, the integrated forming of stiffeners is achieved, optimizing the processing flow. Background Technology

[0002] The following technical problems exist in the traditional processing of ship ribs: The process is complicated: it requires at least three steps, including manual assembly, welding, and multi-part processing, resulting in a lengthy production process.

[0003] Low efficiency: Multiple processes lead to long production cycles. In the traditional method, the daily loss due to process waste can reach 10,000 to 15,000 yuan, and the production efficiency is only 1 / 4 of that after the improvement.

[0004] High costs: The labor costs of manual assembly and welding, as well as the production losses of processing multiple parts (such as material waste and high defect rate), significantly increase costs.

[0005] Unstable quality: Assembly errors result in low dimensional accuracy of stiffeners and insufficient structural strength, failing to meet industrial requirements.

[0006] In summary, the traditional processing mode suffers from the defects of "multi-part step-by-step processing + multi-process connection", which makes it difficult to meet the needs of industrialization in terms of efficiency, cost and quality. There is an urgent need for a special mold that can achieve "one-piece molding" to break through the bottleneck. Summary of the Invention

[0007] In response to the aforementioned technical problems, an integrated special mold for processing integral stiffener plates of ships is provided. Through the coordinated design of the drive mechanism (press and cylinder linkage) and the transmission mechanism (parallel cylinder and push rod transmission), the process is simplified and the production efficiency is improved. It effectively solves the technical problem of low efficiency caused by traditional multi-process processing. Automated processing increases efficiency by 4 times and achieves an accuracy of within ±0.1mm.

[0008] The technical means employed in this invention are as follows: An integrated special mold for machining integral stiffening plates in ships includes: The mold body is made of high-strength alloy steel and includes a cavity adapted to the structure of ship ribs. The cavity is equipped with protrusions, grooves, punching and bending structures for pressing, punching, piercing and pressing lines, and trimming the raw material. The positioning component, located inside the mold body, includes a positioning pin, a limiting post, and a guide pin, for accurately positioning the raw material. The demolding mechanism is movably connected to the mold body and includes a cylinder, a demolding ejector rod, and a guide rail. The demolding ejector rod is driven by the cylinder to move along the guide rail, and the ejection height is ≥ 1.2 times the thickness of the rib plate. The driving mechanism includes a press and an air pressure cover. The press is rigidly connected to the mold base on the mold body to provide power for mold closing and opening. The conveying mechanism includes multiple parallel cylinders I, II, III and push rods, which are connected to the lower mold base via a fixed seat. It is used to drive the raw material to move along the conveying track to complete feeding, processing and discharging.

[0009] This technical solution defines a mold that fully realizes the one-piece molding of ship stiffeners. It integrates the mold body, positioning, demolding, driving and conveying system, replacing the traditional multi-process processing mode. By replacing the assembly and welding of multiple parts through one-piece cavity molding, manual intervention is reduced, and automated demolding and conveying enable continuous processing, increasing production efficiency by 4 times. Precise positioning of components and molding cavity ensures dimensional accuracy within ±0.1mm.

[0010] Furthermore, the mold body is provided with a guide sleeve and a guide post, with the guide sleeve fitted onto the guide post and the gap between the two being ≤0.03mm, to ensure precise alignment of the upper and lower molds.

[0011] This technical solution ensures that the alignment accuracy of the upper and lower molds is ≤0.03mm through the precise cooperation of the guide sleeve and guide pillar, avoiding molding deviations caused by misalignment, reducing offset errors when the mold opens and closes, and ensuring the consistency of the rib plate structure.

[0012] Furthermore, the guide rail of the demolding mechanism is flexibly connected to the cylinder barrel via a slider, and the demolding ejector rod is flexibly connected to the piston rod to adapt to changes in working conditions and ensure automatic reset.

[0013] This technical solution adopts a flexible connection structure (guide rail and cylinder barrel) to adapt to displacement changes caused by pressure fluctuations or workpiece deformation during demolding, thereby improving the reliability of the demolding mechanism, avoiding material jamming or damage to parts, and extending the mold life.

[0014] Furthermore, the cylinder fixing block I and cylinder fixing block II of the conveying mechanism are rigidly connected to the cylinder fixing seat by bolts, and the piston rod drives the push rod to move linearly along the conveying track on the mold body.

[0015] This technical solution ensures the linear motion accuracy of the cylinder and push rod through a rigid connection, maintains the coordination of the conveyor track movement, realizes the precise transfer of raw materials within the mold, reduces positioning deviations, and improves overall processing stability.

[0016] Furthermore, the surface of the mold body cavity is plated with hard chrome, the positioning component is made of aluminum alloy, and the critical dimension tolerance of the cavity is ≤ ±0.01mm.

[0017] This technical solution optimizes mold materials and surface treatment. Alloy steel with hard chrome plating ensures wear resistance and smooth demolding. Aluminum alloy positioning components are lightweight to reduce energy consumption. Tolerance control meets ±0.01mm accuracy, satisfying high-requirement ship structure standards.

[0018] Furthermore, the press output pressure range of the drive mechanism is 10-50MPa, and it is equipped with a gas spring to assist in the mold opening and closing action.

[0019] This technical solution uses a press (10-50MPa) and a gas spring to assist in opening and closing the mold, balancing the molding pressure requirements with ease of operation, reducing the physical burden on operators, and adapting to the processing needs of ribs of different thicknesses.

[0020] A method for using an integrated special mold for machining integral stiffening plates in ships includes the following steps: Step 1, Raw material positioning: Place the pre-cut rib plate raw material into the guide groove of the positioning component and fix it by the positioning pin, limiting post and guide pin; Step 2, Raw material conveying: The push rod is driven by cylinders I, II and III of the conveying mechanism to convey the raw material from the feeding end to the processing station; Step 3, mold closing and forming: Start the press of the drive mechanism to press down the upper mold base. The raw material passes through the cavity of the mold body in sequence through pressing ribs, punching, turning and pressing lines, trimming and forming to achieve one-piece forming; Step 4: After molding, activate the demolding mechanism. The demolding ejector pin will push the product out and automatically reset after demolding. Step 5: Cleaning and maintenance: Periodically clean the mold cavity, positioning components and demolding mechanism residues, and check the wear of connecting parts.

[0021] This technical solution standardizes automated operation processes, including raw material positioning, conveying, mold closing and forming, and demolding and part removal. Standardized production processes reduce human error; maximize efficiency with seamless transitions between steps, minimizing downtime; and extend maintenance cycles through regular cleaning to prolong mold life.

[0022] Furthermore, the ejection stroke of the ejector pin is set to 1.2 to 1.5 times the thickness of the rib plate to ensure complete demolding and avoid material jamming.

[0023] This technical solution limits the ejection stroke of the demolding ejector pin to 1.2 to 1.5 times the thickness of the rib plate, ensuring complete demolding and avoiding excessive ejection that could damage the mold, reducing the risk of material jamming, minimizing mold wear, and improving production continuity.

[0024] Compared with the prior art, the present invention, which adopts the above technical solution, has the following advantages: Efficiency Improvement: Traditional multi-process manufacturing requires "assembly → welding → processing", while this invention eliminates intermediate steps through one-piece molding, increasing production efficiency by more than 4 times.

[0025] Costs sharply reduced: Labor costs: Reduce reliance on positions such as "assemblers and welders", reducing labor input to 1 / 3 to 1 / 4 of the original; Production losses: One-piece molding avoids material waste and welding defects caused by processing multiple parts, reducing daily losses by 30% to 50%.

[0026] Quality upgrade: One-piece molding with no assembly gaps, the dimensional accuracy (within ±0.1mm) and structural strength of the stiffeners are significantly better than traditional processes.

[0027] Versatility expansion: By replacing the molding module and positioning mechanism, it can be adapted to the processing of ship stiffeners of different specifications, and the mold has strong reusability. Attached Figure Description

[0038] like Figures 1 to 6The integrated special mold shown includes: The mold body 1 is made of high-strength alloy steel and includes a cavity adapted to the structure of ship ribs. The cavity is equipped with protrusions, grooves, punches and bending structures for pressing, punching, piercing and pressing lines, and trimming the raw material; providing basic space and shape constraints for rib forming.

[0039] The specific structure includes: lower support plate 111, lower pad 112, lower mold base 113, lower back plate 114, lower pad 115, lower template 116, upper support plate 117, stop plate 118, upper clamping plate 119, upper pad 120, upper 121, back plate, upper mold base 122, upper pad 123, gas spring 124, guide post 125, guide sleeve 126, material 127, unloading bin 128, etc. The lower support plate 111, lower mold base 113, lower template 116, upper mold base 122, and upper support plate 117 are stacked and assembled in sequence; Positioning component 2 is located inside the mold body and includes positioning pin 21, limiting post 22 and guide pin 23. It is fixed to the surface of the lower template 116 by bolts or welding and is used to accurately position the raw material. The demolding mechanism 3 is movably connected to the mold body 1 and includes: push block 311, demolding ejector rod 312, guide rail 313, cylinder 314, cylinder fixing plate 315, etc. The ejector pin is driven by the cylinder to move along the guide rail, and the ejection height is ≥ 1.2 times the thickness of the rib plate. After the rib plate is formed, the formed product can be smoothly ejected from the mold cavity, which is convenient for picking up the part, and can be automatically reset to prepare for the next processing.

[0040] The drive mechanism 4 primarily converts the pressure energy of compressed air into mechanical energy to power the mold, driving related mold components to achieve reciprocating linear motion for mold closing and opening, thereby completing the processing operation of the rib plate. It includes a press 411 and an air pressure cover 412. The press is rigidly connected to the upper mold base 122 of the mold body, providing power for mold closing and opening. Conveying mechanism 5, with its control cylinders for conveying the rib plates, is the core power component of the automated mold conveying system. Its main function is material conveying and positioning. Through the reciprocating linear motion of the cylinders, the rib plates are pushed or pulled along the conveying track, achieving orderly conveying of the rib plates from the feeding end to the processing station and then to the discharging end, ensuring the continuity of the processing flow. It includes multiple parallel cylinders I 515, II 516, and III 517, and a push rod 511. These are connected to the lower mold base 113 via cylinder fixing blocks I 512 and II 513, and are used to drive the raw material along the conveying track to complete feeding, processing, and discharging.

[0041] All components of the mold fit together tightly. The lower support plate 111 and the upper mold base 122 are located at the bottom and top of the upper and lower molds, respectively, bearing the weight of the mold and connecting the equipment. The lower pad 112 and the upper pad 123 support the mold and adjust the spacing and level. The lower template 116 and the upper support plate 117 are in the middle layer and are the forming core, where the raw material is formed in the internal cavity. The remaining plates are distributed in an orderly manner in the middle layer. The lower back plate 114 and the upper back plate 121 enhance the rigidity of the mold base, and the lower pad 115 and the upper pad 120 adjust the height and distribute the pressure. The upper clamping plate 119 fixes the upper mold forming part, the stop plate 118 limits the opening and closing stroke of the mold, the gas spring 124 assists in opening and closing the mold, and the guide sleeve 126 cooperates with the guide post 125 to ensure precise alignment of the upper and lower mold bases, ensuring the stability of the material position during processing. The fit clearance between the guide sleeve and the cavity of the mold body 1 is strictly controlled to ensure the forming quality of the rib plate.

[0042] The positioning mechanism 2 is fixed to the preset hole position of the mold body by welding or bolting, and is firmly connected to the inner wall of the mold body to ensure accurate placement of raw materials.

[0043] The cylinder 314 of the demolding assembly 3 is movably connected to the mold body 1 via the guide rail 313. That is, the cylinder barrel is mounted on the guide rail fixed to the mold body 1 by means of a slider, and the piston rod is flexibly connected to the demolding ejector rod 312 to form a connection structure of "guide rail guidance + movable support". This can not only ensure the linear accuracy of the ejection action, but also adapt to changes in mold working conditions, and achieve efficient demolding and automatic reset.

[0044] The press 411 of the drive mechanism 4 serves as the power source and is rigidly fixed to the upper mold base 122 of the mold body 1 to ensure stable power transmission. The cylinder assembly of the air pressure cover 412 is linked to the mold body 1 through a movable connection to achieve reciprocating linear motion, forming a connection logic of "pneumatic drive + mechanical transmission".

[0045] The conveying mechanism 5 is connected to the mold body 1 through a rigid support structure of "cylinder fixing seat 514 + cylinder fixing block I 512 and cylinder fixing block II 513": the cylinder fixing seat 514 is bolted to the lower mold base 113 of the mold, and cylinders I 515, II 516 and III 517 are respectively installed on the fixing seat 514 through cylinder fixing blocks I 512 and II 513. The piston rod is rigidly connected to the push rod 511, and the push rod 511 moves linearly along the conveying track on the mold body; multiple sets of cylinders are driven in parallel, and through the air circuit system integrated into the mold body, a "fixed support - multi-cylinder drive - guide rail guidance" conveying system is formed to realize the precise conveying of the rib plate between the feeding end, processing station and discharge end.

[0046] Furthermore, the mold body is provided with a guide sleeve 126 and a guide post 125. The guide sleeve is fitted onto the guide post, and the gap between the two is ≤0.03mm, ensuring precise alignment of the upper and lower molds.

[0047] This technical solution, through the precise cooperation between the guide sleeve 126 and the guide post 125, ensures that the alignment accuracy of the upper and lower molds is ≤0.03mm, avoids molding deviation caused by misalignment, reduces offset error when the mold is opened and closed, and ensures the consistency of the rib plate structure.

[0048] Furthermore, the guide rail 313 of the demolding mechanism is flexibly connected to the cylinder barrel of the cylinder 314 via a slider, and the demolding ejector rod 312 is flexibly connected to the piston rod to adapt to changes in working conditions and ensure automatic reset.

[0049] This technical solution adopts a flexible connection structure (guide rail and cylinder barrel) to adapt to displacement changes caused by pressure fluctuations or workpiece deformation during demolding, thereby improving the reliability of the demolding mechanism, avoiding material jamming or damage to parts, and extending the mold life.

[0050] Furthermore, the cylinder fixing block I 512 and cylinder fixing block II 513 of the conveying mechanism are rigidly connected to the cylinder fixing seat 514 by bolts, and the piston rod drives the push rod 511 to move linearly along the conveying track on the mold body.

[0051] This technical solution ensures the linear motion accuracy of the cylinder and push rod through a rigid connection, maintains the coordination of the conveyor track movement, realizes the precise transfer of raw materials within the mold, reduces positioning deviations, and improves overall processing stability.

[0052] Furthermore, the surface of the mold body cavity is plated with hard chrome, the positioning component is made of aluminum alloy, and the critical dimension tolerance of the cavity is ≤ ±0.01mm.

[0053] This technical solution optimizes mold materials and surface treatment. Alloy steel with hard chrome plating ensures wear resistance and smooth demolding. Aluminum alloy positioning components are lightweight to reduce energy consumption. Tolerance control meets ±0.01mm accuracy, satisfying high-requirement ship structure standards.

[0054] Furthermore, the pressure output range of the drive mechanism press 411 is 10-50MPa, and it is equipped with a gas spring 124 to assist in the mold opening and closing action.

[0055] This technical solution uses a press (10-50MPa) and a gas spring to assist in opening and closing the mold, balancing the molding pressure requirements with ease of operation, reducing the physical burden on operators, and adapting to the processing needs of ribs of different thicknesses.

[0056] A method for using an integrated special mold for machining integral stiffening plates in ships includes the following steps: Step 1, raw material positioning: Place the pre-cut rib plate raw material into the guide groove of the positioning component 2 and fix it by the positioning pin 21, the limiting post 22 and the guide pin 23; Step 2, raw material conveying: The push rod 511 is driven by cylinders I 515, II 516 and III 517 of the conveying mechanism 5 to convey the raw material from the feeding end to the processing station. Step 3, Mold Closing and Forming: The press 411 of the drive mechanism 4 is activated, causing the upper mold base 122 to press down. The raw material, within the cavity of the mold body 1, undergoes sequential processes including pressing ribs, punching, flanging, pressing lines, trimming, and forming to achieve integral molding. Figure 7 As shown; Step 4: After molding, the demolding mechanism 3 is activated, and the demolding ejector 312 ejects the product, which automatically resets after demolding. Step 5: Cleaning and maintenance: Periodically clean the mold cavity, positioning components and demolding mechanism residues, and check the wear of connecting parts.

[0057] This technical solution standardizes automated operation processes, including raw material positioning, conveying, mold closing and forming, and demolding and part removal. Standardized production processes reduce human error; maximize efficiency with seamless transitions between steps, minimizing downtime; and extend maintenance cycles through regular cleaning to prolong mold life.

[0058] Furthermore, the ejection stroke of the ejector pin 312 is set to 1.2 to 1.5 times the thickness of the rib plate to ensure complete demolding and avoid material jamming.

[0059] This technical solution limits the ejection stroke of the demolding ejector pin to 1.2 to 1.5 times the thickness of the rib plate, ensuring complete demolding and avoiding excessive ejection that could damage the mold, reducing the risk of material jamming, minimizing mold wear, and improving production continuity. Specific Implementation Example 1 (1) Precision machining Material selection: The main body of the mold and the forming module are made of high-strength alloy steel (42CrMo), which is heat-treated to improve hardness and toughness; the positioning mechanism can be made of aluminum alloy, which is lightweight and easy to install.

[0061] Manufacturing process: The cavity of the molding module is formed with high precision by CNC milling and EDM; the positioning components and demolding components are processed by CNC turning and wire cutting, and the key dimensional tolerances are controlled within ±0.01mm.

[0062] Surface treatment: Nitriding treatment on the surface of the molding cavity, hard chrome plating on the surface of the molding module cavity to reduce demolding friction; rust prevention treatment on the surface of the mold body.

[0063] (2) Assembly and debugging Install the mold body, positioning mechanism, demolding components, drive and conveying mechanism in sequence, nest and fasten each cavity of the mold body, check the fit clearance to ensure that the clearance is uniform and the error is ≤0.03mm.

[0064] Adjust the ejection stroke of the demolding assembly (ensure the ejection height is ≥ 1.2 times the thickness of the rib plate to avoid jamming).

[0065] Working principle or operating method: (1) Working principle: Utilizing the cavity and forming module of the mold body 1, the raw material for integrated ship ribs undergoes various shape constraints and pressure processes, including rib pressing, punching, flanging, pressing lines, preliminary forming, trimming, intermediate forming, two-sided forming, and integrated forming, allowing the raw material to be formed into a product with a rib structure in one step within the mold. Positioning component 2 ensures precise positioning of the raw material, avoiding forming deviations; demolding mechanism 3 ejects the product after forming, completing the processing cycle. This replaces the traditional step-by-step processing of "multi-part assembly + welding." Drive mechanism 4 provides processing pressure to the mold body, completes mold opening and closing actions, and focuses on the stability of gravity output and stroke control. Rib conveying mechanism 5 controls the linear motion of the cylinder to convert the linear motion of the rib into horizontal conveying of the rib, performing material transfer and positioning.

[0066] (2) Operating method Raw material feeding: Clean the mold body 1 and positioning mechanism 2, put the rib plate raw material (cut into preset size) into the guide groove of positioning mechanism 2, and fix the position of the raw material through structures such as 21. positioning pin; 22. limiting post; 23. guide pin, etc., to ensure that the raw material is compatible with the mold cavity and forming module position.

[0067] Precise transmission: The transmission mechanism 5 is driven by cylinders I 515, II 516 and III 517 in parallel, so that the push rod 511 moves linearly along the transmission track on the mold body. Through the air circuit system integrated into the mold body, a transmission system of "fixed support - multi-cylinder drive - guide rail guidance" is formed to realize the precise transmission of the rib plate between the feeding end, processing station and discharge end.

[0068] Mold closing and forming: Start the press 411 of the drive mechanism 4, press down the upper mold base 122 to close the mold, and the raw material is subjected to the action of the pressure mold in the cavity to perform rib pressing, punching, hole turning, pressing line, preliminary forming, edge trimming, intermediate forming, and two-side forming, forming an integral product of ship rib plate.

[0069] Demolding and part removal: After molding, the demolding assembly 3 is activated. The demolding ejector 312, under the action of the cylinder 314, pushes the rib plate out of the cavity. With the help of the conveying mechanism 5, the part is removed by the conveyor belt. The demolding ejector 312 automatically resets, ready for the next processing.

[0070] Mold cleaning and maintenance: Regularly clean residual waste and oil stains from mold cavities, molding modules, positioning components, demolding mechanisms, etc., check for mold wear and loose connections, and repair or replace damaged parts in a timely manner to ensure continuous and stable mold operation.
