Description

Technical Field

[0001] This invention relates to the field of stamping and forming production technology, specifically a stamping and forming mold for gas cylinder heads that facilitates material handling. Background Technology

[0002] Gas tank head stamping dies are key process equipment used to manufacture end caps for high-pressure vessels (such as liquefied gas tanks and gas storage tanks). They process metal sheets into hemispherical or dish-shaped heads with specific curvatures through plastic deformation. These dies typically consist of an upper die, a lower die, and a matching demolding mechanism. They require high-tonnage presses to complete the material stretching, forming, and demolding processes, and have stringent requirements for forming accuracy, surface finish, and structural strength. They are widely used in petrochemical, energy equipment, and other fields. During gas tank head stamping operations, demolding and unmolding are usually required after stamping, and these operations need to be performed using demolding tools.

[0003] The following problems still exist in the current stamping and forming of gas cylinder heads:

[0004] 1. The gas cylinder head stamping die is generally cumbersome and inefficient in the material handling process. During the stamping process, due to the eccentric offset of the die during stamping, the positioning accuracy is insufficient and the material jamming is likely to occur. The processing accuracy is not good enough, and the convenience of material handling is also affected.

[0005] 2. After the stamping process is completed, the mold is easily stuck inside the mold base, requiring manual removal and placement of materials using tools. The material removal is relatively inconvenient, and the automated lifting and pushing capabilities are poor. This not only prolongs the production cycle of a single piece but also causes scratches or deformation on the surface of the workpiece, resulting in a significant reduction in the yield rate. Summary of the Invention

[0006] Technical problems to be solved

[0007] To address the aforementioned problems, this invention provides a convenient material handling stamping die for gas cylinder heads. This solves the common problems of cumbersome operation and low efficiency in the material handling process of gas cylinder head stamping dies. During the stamping process, eccentric offset of the die during stamping leads to insufficient positioning accuracy and easy jamming, resulting in poor processing precision and affecting material handling convenience. Furthermore, after stamping, the die easily gets stuck inside the die holder, requiring manual material handling with tools, further complicating material handling convenience. The automated lifting and pushing capabilities are also poor, extending the single-piece production cycle and causing scratches or deformation on the workpiece surface, significantly reducing the yield rate.

[0042] Reference Figure 1-6 A gas cylinder head stamping mold for easy material handling includes a stamping platform 1, and a pressure gas cylinder 2 is provided on one side of the stamping platform 1.

[0043] A stamping die 5 is provided at the center of the top of the stamping forming table 1. Both sides of the bottom of the die opening of the stamping die 5 are provided with push-material mounting cavities 6. Both push-material mounting cavities 6 are filled with lifting push-material components 7.

[0044] Among them, the bottoms of multiple material pushing installation cavities 6 are connected, the output end of the pressure inflation tank 2 is connected to multiple material pushing installation cavities 6, the stamping and pressure-bearing mold 5 is provided with a trigger-type sensing component 9, and the output pipe of the pressure inflation tank 2 is provided with a control valve 21.

[0045] The top of the stamping forming table 1 is provided with a stamping lifting assembly 3, and the bottom of the inner side of the stamping lifting assembly 3 is provided with a stamping pressing die 4;

[0046] Specifically, the stamping lifting assembly 3 drives the pressing die 4 to press downwards, cooperating with the stamping pressure die 5 to stamp the material into a head. The bottom of the stamping pressure die 5 has push-material mounting cavities 6 on both sides. Each of the two push-material mounting cavities 6 has a corresponding lifting push-material assembly 7. The push-material mounting cavities 6 can dampen and limit the lifting push-material assembly 7. A pressure inflation tank 2 is located on the side of the stamping forming table 1. The pressure inflation tank 2 can be inflated to pressurize the two sets of push-material mounting cavities 6 for stamping operations. The lifting push-material assembly 7 inside the push-material mounting cavity 6 can be subjected to air pressure to pressurize and push downwards. The upper displacement pushes the stamped gas cylinder head to remove the mold, allowing it to detach from the stamping pressure mold 5. After mold opening, pressure injection stops, and the return spring 73 is in a relaxed and taut state. After pushing, the return spring 73 can retract elastically, driving the lifting and pushing component 7 to retract into the pushing installation cavity 6, completing the pushing and retraction. The trigger-type sensor component 9 can be triggered during stamping to control the control valve 21 to perform pressure injection, completing automated pushing and automated mold removal. The device automatically pushes and discharges materials, making it less likely to scratch the workpiece during removal, thus improving production efficiency and yield.

[0047] As an optimized solution of the present invention, such as Figure 1-6 As shown, the stamping lifting assembly 3 includes a support frame 31 that is fixed to the top of the stamping forming table 1 by bolts. The top of the support frame 31 is provided with a lifting hydraulic cylinder 32 that drives the stamping pressing die 4 to move in the vertical direction. A fixed mounting seat 34 is fixedly installed at the bottom of the lifting hydraulic cylinder 32. The bottom of the fixed mounting seat 34 is bolted to the top of the stamping pressing die 4.

[0048] Specifically, the lifting hydraulic cylinder 32 is installed on the top of the support frame 31, which can support and bear the load. The lifting hydraulic cylinder 32 can control the lifting and lowering of the stamping die 4. After the lifting hydraulic cylinder 32 is running, it can drive the stamping die 4 downward to perform stamping and forming operations. The fixed mounting base 34 is set to facilitate the installation of the stamping die 4 on the bottom of the fixed mounting base 34. The bolted installation is relatively convenient and the disassembly and assembly are simple.

[0049] As an optimized solution of the present invention, further, anti-deviation limiting seats 33 are provided on both sides of the stamping die 4. The anti-deviation limiting seats 33 are correspondingly slidably sleeved on both sides of the support frame 31. The stamping die 4 is located directly above the stamping die 5 and the structures match.

[0050] The bottom of the fixed mounting base 34 is provided with an anti-offset fixing opening 35. The top of the stamping die 4 is fixedly installed with an anti-offset fixing block 36. The bottom of the anti-offset fixing block 36 extends and engages in the anti-offset fixing opening 35. Both sides of the fixed mounting base 34 and the stamping die 4 are provided with fixed bolt seats 37. Two adjacent fixed bolt seats 37 are bolted and fixed with fixing bolts 38.

[0051] Specifically, by setting anti-deviation limit seats 33, when the stamping die 4 is raised and lowered for stamping, its two sides can be limited by the anti-deviation limit seats 33, so that when the stamping die 4 is raised and lowered, the two anti-deviation limit seats 33 can rise and fall accordingly, and at the same time, they can rise and fall on both sides of the support frame 31, which plays an anti-deviation and fixing role, so that the stamping die 4 remains stable during stamping, the center of gravity remains stable, the positioning is accurate, it is not easy to tilt and jam, and it is easy to remove the material;

[0052] During the installation of the stamping die 4, the anti-offset fixing block 36 can be inserted and snapped into the anti-offset fixing port 35, which facilitates the precise installation of the stamping die 4 on the bottom of the fixed mounting base 34. The installation accuracy is high, it is not easy to offset or tilt, and the fixing effect is good. Furthermore, the stamping die 4 and the fixed mounting base 34 are bolted together by the fixed bolt seat 37 and the fixed bolt 38, which makes the installation simple and convenient, and the disassembly and installation are relatively simple, making it suitable for use.

[0053] As an optimized solution of the present invention, the two pusher mounting cavities 6 are symmetrically distributed on both sides of the mold opening of the stamping pressure die 5. The pusher mounting cavity 6 includes an upper pusher port 61 and a lower bearing port 62. The lifting pusher assembly 7 is correspondingly slidably sealed in the upper pusher port 61. The inner diameter of the upper pusher port 61 is larger than the inner diameter of the lower bearing port 62. The front view cross section of the upper pusher port 61 and the lower bearing port 62 is a convex combination.

[0054] Specifically, by setting two pusher mounting cavities 6 symmetrically distributed on both sides of the die opening of the stamping pressure die 5, two sets of lifting pusher components 7 can be set up to push and discharge material to both sides of the end cap, making material discharge convenient. The pusher mounting cavity 6 includes an upper push port 61 and a lower bearing port 62. The upper push port 61 is damped and fitted with the damping movable push column 71, and the lower bearing port 62 is fitted and fixed with the support rod 72 and the spring spring 73. When the pusher mounting cavity 6 is inflated, the damping movable push column 71 and the support rod 72 can be pushed upward. The spring spring 73 is in a relaxed and taut state. After the push is completed, the spring spring 73 can retract with elastic force. The automatic elastic force recovery is convenient. The inflation push and the spring retraction are convenient for automatic mold removal.

[0055] As an optimized solution of the present invention, further, an inflatable inner cavity 8 is provided on the inner wall of the bottom of the stamping and pressing die 5. The top of the inflatable inner cavity 8 is connected to the bottom of the two pusher mounting cavities 6 respectively. The output end of the pressure inflation tank 2 is connected to the inflatable inner cavity 8. The top of the lifting pusher assembly 7 is adapted to fit the bottom of the die opening of the stamping and pressing die 5.

[0056] Specifically, by setting up an inflation chamber 8, which is connected to the bottom of the two material pushing installation chambers 6 respectively, the pressure inflation tank 2 can simultaneously inflate and pressurize the two sets of material pushing installation chambers 6 when it is inflating. This allows the material pushing installation chambers 6 on both sides to simultaneously push the two sets of lifting material pushing components 7 to push and discharge material to both sides of the end cap. The material pushing is convenient to use. By setting up a control valve 21, the flow rate, pressure and on / off control can be performed when the pressure inflation tank 2 is inflating or stopping. The control is convenient and suitable for use.

[0057] As an optimized solution of the present invention, the lifting and pushing assembly 7 further includes a damping movable push column 71, a support rod 72 and a rebound spring 73. The support rod 72 is fixedly installed on the bottom of the damping movable push column 71. The damping movable push column 71 fills and dampens the upper part of the pushing installation cavity 6. The bottom of the support rod 72 extends to the lower part of the pushing installation cavity 6. The rebound spring 73 is sleeved on the support rod 72. The rebound spring 73 is fixedly connected to the support rod 72 and the pushing installation cavity 6 respectively. The rebound spring 73 is kept in a relaxed state.

[0058] Specifically, by setting the lifting and pushing assembly 7, which includes a damping movable push column 71, a support rod 72, and a rebound spring 73, the damping movable push column 71 can dampen the top of the material pushing installation cavity 6, and the support rod 72 is inserted and limited at the bottom of the material pushing installation cavity 6. The material pushing installation cavity 6 can dampen and limit both the damping movable push column 71 and the support rod 72. The rebound spring 73 retracts under the influence of the elastic force, driving the damping movable push column 71 and the support rod 72 to retract into the material pushing installation cavity 6, completing the pushing and retraction, which facilitates automated mold removal and makes mold removal convenient.

[0059] As an optimized solution of the present invention, a metal support plate 74 is further fixedly installed on the top of the damping movable push column 71. The metal support plate 74 is fitted to the top of the inner side of the pusher mounting cavity 6, and the top of the metal support plate 74 is adapted to fit and fit the bottom of the die opening of the stamping pressure die 5.

[0060] Specifically, the metal support plate 74 can provide a close support for the damping movable push column 71. The damping movable push column 71 and the metal support plate 74 can be filled into the interior of the upper push port 61. When the stamping die 4 and the stamping pressure die 5 are stamped, the metal support plate 74 can provide support to prevent the material from forming a pit due to the depression of the push installation cavity 6 during die casting. The metal support plate 74 can fit the bottom of the die opening of the stamping pressure die 5, and has excellent adaptability.

[0061] As an optimized solution of the present invention, the trigger-type sensing component 9 further includes a trigger-type sensor 91 and a trigger-type lifting block 92. The trigger-type sensor 91 is installed on the side of the stamping die 4, and the trigger-type lifting block 92 is installed on the top of the stamping table 1. The trigger-type lifting block 92 is located directly above the trigger-type sensor 91. The trigger-type sensor 91 is electrically connected to the control valve 21, and the control valve 21 is an electronic valve body.

[0062] Specifically, the trigger-type sensing component 9 includes a trigger-type sensor 91 and a trigger-type lifting block 92. The trigger-type sensor 91 is correspondingly disposed on the side of the stamping die 5, and the trigger-type lifting block 92 is correspondingly installed on the side of the stamping die 4. The trigger-type sensor 91 and the trigger-type lifting block 92 are vertically aligned. The trigger-type lifting block 92 can move downward with the stamping die 4. When the stamping die 4 and the stamping die 5 are performing stamping operations, the trigger-type lifting block 92 can follow and contact the trigger-type sensor 91 to trigger. After being triggered, the trigger-type sensor 91 can control the control valve 21, so that the pressure inflation tank 2 can inflate and pressurize the pusher installation cavity 6, and then the lifting pusher component 7 can push the material. It is convenient to use. The control valve 21 is an electronic valve body, which can be automatically controlled for on / off control. The automated operation is convenient and does not require manual intervention, thus improving stamping efficiency.

[0063] As an optimized solution of the present invention, further, an oil film pressurizing tank 10 is provided on the side of the stamping and pressing mold 5 away from the pressure inflation tank 2. The output end of the oil film pressurizing tank 10 extends into the inflation cavity 8. An oil spray nozzle 11 is provided at the output end of the oil film pressurizing tank 10. The output end of the trigger-type sensing component 9 is electrically connected to the input end of the oil spray nozzle 11. An oil film separating mesh 12 is provided at the top of the inflation cavity 8.

[0064] Specifically, the output end of the oil film pressurizing tank 10 is correspondingly located within the inflation chamber 8. The oil spray nozzle 11 controls the spraying and closing of the lubricating oil film within the oil film pressurizing tank 10. The oil film pressurizing tank 10 is a pressurizing pipe body. When the oil spray nozzle 11 is open, it can quickly spray out an oil film. When the trigger-type sensing component 9 is pressed and triggered, it can simultaneously trigger the oil spray nozzle 11 to start oil spraying. At the same time, the pressurized inflation tank 2 can perform air jet operation. During the oil spraying process, the air jet pressure can be used to spray lubricating oil. The oil is introduced into the pusher mounting cavity 6 to replenish the lubricating oil film of the pusher mounting cavity 6 and the die opening of the stamping pressure die 5. The oil film separator 12 allows the lubricating oil to be pneumatically cut and separated into small water droplets while being pneumatically guided. This facilitates uniform pneumatic spraying of the lubricating oil film, resulting in high spray uniformity. The stamping process is also optimized. At the same time, the damping of the lifting pusher assembly 7 and the pusher mounting cavity 6 is not prone to jamming, ensuring stable lubrication and convenient use.

[0065] As an optimized solution of the present invention, further, anti-offset mounting ports 51 are provided on both sides of the top of the stamping forming table 1, and anti-offset fixing plates 52 are provided on both sides of the bottom of the stamping pressure die 5. The two anti-offset fixing plates 52 are inserted and engaged with the inner side of the two anti-offset mounting ports 51. Right angle bolts 53 are provided on both sides of the stamping pressure die 5. Mounting bolts 54 are provided on both sides inside the right angle bolts 53. Multiple mounting bolts 54 are installed on the stamping pressure die 5 and the stamping forming table 1 respectively. The stamping pressure die 5 is bolted and fixed to the top of the stamping forming table 1 by the right angle bolts 53.

[0066] Specifically, when installing the stamping pressure die 5, the anti-displacement fixing piece 52 is first inserted and fitted into the anti-displacement mounting port 51 to prevent displacement and fix it, so that the die has a high tightness when it is closed and the installation accuracy is excellent. The right angle bolt 53 cooperates with the mounting bolt 54 to facilitate the bolting and fixing of the stamping pressure die 5 onto the stamping forming table 1. The installation is convenient, suitable for use, and the mold closing effect is good and it is not easy to tilt or deviate.

[0067] Working principle:

[0068] S1: A stamping lifting assembly 3 is installed on the top of the stamping forming table 1. The stamping lifting assembly 3 includes a support frame 31 and a lifting hydraulic cylinder 32. The lifting hydraulic cylinder 32 is installed on the top of the support frame 31 and can support and bear the load. The lifting hydraulic cylinder 32 can control the lifting of the stamping die 4. After the lifting hydraulic cylinder 32 is running, it can drive the stamping die 4 to move downward to perform stamping forming operation.

[0069] S2: A stamping pressure die 5 is provided on the top of the stamping forming table 1. The material to be stamped can be placed on the stamping pressure die 5. The stamping lower die 4 is positioned corresponding to the stamping pressure die 5. When the stamping lower die 4 moves downward for die casting, it can stamp the material to be stamped on the top of the stamping pressure die 5 to form a gas cylinder head, thus completing the production process. When the stamping lower die 4 is raised and lowered for stamping, its two sides can be limited by anti-deviation limit seats 33. When the stamping lower die 4 is raised and lowered, the two anti-deviation limit seats 33 can move up and down accordingly. At the same time, the two sides of the support frame 31 are raised and lowered to play an anti-deviation fixing role, so that the stamping lower die 4 remains stable during stamping, the center of gravity remains stable, the positioning is accurate, and it is not easy to tilt or jam the material, making it easy to pick up the material.

[0070] S3: The bottom of the die opening of the stamping die 5 is provided with pusher mounting cavities 6 on both sides. The interior of each pusher mounting cavity 6 is provided with a lifting pusher assembly 7. The lifting pusher assembly 7 includes a damping movable pusher 71, a support rod 72 and a rebound spring 73. The damping movable pusher 71 can dampen the top of the pusher mounting cavity 6. The support rod 72 is inserted and limited at the bottom of the pusher mounting cavity 6. The pusher mounting cavity 6 can dampen and limit the damping movable pusher 71 and the support rod 72. The rebound spring 73 can support the support rod 72 to keep it in the center of the contraction.

[0071] S4: A pressure inflation tank 2 is provided on the side of the stamping forming table 1. The output end of the pressure inflation tank 2 is connected to two sets of push-material mounting cavities 6. When the material ejection operation is required, the pressure inflation tank 2 can be inflated to pressurize the two sets of push-material mounting cavities 6 for stamping operation. The damping movable push column 71 and support rod 72 in the push-material mounting cavity 6 can be displaced upward by air pressure, so that the damping movable push column 71 can be pushed upward by pressure to push the stamped gas cylinder head to remove the mold. It is not easy to get stuck on the stamping pressing die 4. The two sets of lifting push-material components 7 open the mold on both sides of the head. After the mold opening is completed, the pressure injection stops. The rebound spring 73 is affected by the elastic force and retracts, which drives the damping movable push column 71 and support rod 72 to retract into the push-material mounting cavity 6 to complete the push and retraction. The trigger-type sensor component 9 can be triggered during stamping to control the control valve 21 to perform pressure injection operation, complete the automated push-material and automated mold removal.

[0072] S5: The pusher installation cavity 6 includes an upper pusher port 61 and a lower bearing port 62. The upper pusher port 61 is damped and fitted with the damping movable pusher 71, and the lower bearing port 62 is fitted and fixed with the support rod 72 and the rebound spring 73. When the pusher installation cavity 6 is filled with air, the damping movable pusher 71 and the support rod 72 can be pushed upward. The rebound spring 73 is in a relaxed and taut state. After the push is completed, the rebound spring 73 can retract elastically, driving the damping movable pusher 71 and the support rod 72 to retract into the pusher installation cavity 6, which is convenient for secondary die casting push. It is more convenient to use, keeps the center of gravity of the device stable, and has a good anti-deviation and anti-jamming effect in die casting. Moreover, the automatic pusher and discharge makes it less likely to scratch the workpiece when picking it up, thus improving production efficiency and yield.
