Description

Technical Field

[0001] This invention relates to the field of stamping and forming technology, and in particular to a flexible positioning process for stamped and formed sheet materials. Background Technology

[0002] In sheet metal stamping, flexible positioning, mold combination, and operational safety directly determine the forming accuracy, production efficiency, and operational safety. This process is widely used in the large-scale production of products such as hardware sheets, automotive sheet metal, and electronic component housings. Existing sheet metal stamping positioning processes, when using multi-mold combinations, require manual disassembly and reassembly of the molds each time sheet metal is loaded or unloaded. This process is cumbersome, time-consuming, and labor-intensive. Furthermore, manual assembly can lead to loose mold fit, which is easily loosened by external vibrations during stamping, resulting in gaps and causing sheet metal positioning deviations and forming defects. During loading and unloading, the stamping structure lacks an automatic locking mechanism; accidental initiation of stamping can easily cause personal injury, posing a significant safety hazard. Sheet metal positioning often uses rigid positioning methods, which are prone to gaps during positioning and cannot accommodate minute dimensional deviations in the sheet metal, leading to inaccurate positioning and affecting forming accuracy. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing stamping sheet positioning processes, which require manual disassembly and assembly of the mold for each sheet loading and unloading operation. These processes are cumbersome, time-consuming, and labor-intensive. Furthermore, manual assembly can lead to loose mold fit, which is susceptible to loosening and gaps during stamping due to external vibrations. Additionally, the lack of an automatic locking mechanism in the stamping structure during loading and unloading can easily cause personal injury due to accidental start-up of the stamping process, posing significant safety hazards. Sheet positioning often employs rigid positioning methods, which are prone to gaps during positioning and cannot accommodate minute dimensional deviations in the sheet, resulting in inaccurate positioning and affecting forming accuracy. Therefore, this invention proposes a flexible positioning process for stamping sheet.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A flexible positioning process for stamped sheet metal uses a flexible positioning device, which includes a flexible positioning mechanism. The process of using the flexible positioning device to flexibly position the stamped sheet metal is as follows: S1. The flexible stamping component drives the flexible stamping component and the capping component to smoothly and flexibly position and stamp the sheet material downwards. S2. After molding, the flexible extrusion component is reset and the capping operation with the molding component is completed. S3. Finally, operate the molding components to demold the product. The flexible positioning mechanism includes an assembly frame on which a flexible stamping component, a limiting component, and a forming component are assembled. A driving component and a cap removal component are provided on both sides of the flexible stamping component.

[0005] Preferably, the flexible stamping assembly includes a stamping device and an upper die end cap. The stamping device is mounted on an assembly frame, and an mounting plate is installed at one end of the stamping device. Ball end sliding parts are fixedly connected to both sides of the mounting plate.

[0006] Preferably, a punching head is fixedly connected to the lower part of the mounting plate, the punching head is disposed through the upper die end cover, and a flexible pad and two positioning rods are fixedly connected to the lower part of the upper die end cover.

[0007] Preferably, the drive assembly includes a rotating shaft, which is rotatably mounted on the assembly frame via bearings. A drive gear is mounted on the top end of the rotating shaft. A limit hole is formed on the rotating shaft, and a sleeve is fitted onto the rotating shaft. The sleeve is mounted on the upper mold end cover.

[0008] Preferably, the rotating shaft is further provided with a spiral groove and two vertical grooves, the two vertical grooves being connected to the upper and lower ends of the spiral groove, and the ball end sliding part being able to slide in the spiral groove and the vertical grooves.

[0009] Preferably, the cap removal assembly includes a screw, which is rotatably mounted on an assembly frame via a bearing. A driven gear is mounted on the top end of the screw, which meshes with a driving gear. A limit port is provided on the screw, and a nut is threaded onto the screw. The nut is mounted on the upper mold end cap.

[0010] Preferably, the limiting component includes a fixing plate, four elastic structures are fixedly connected to the side of the fixing plate, a connecting plate is fixedly connected to one end of two elastic structures, and two limiting rods are fixedly connected to the side of the connecting plate. The size of the limiting rods is adapted to the size of the limiting opening and the limiting hole.

[0011] Preferably, the molding assembly includes an arc-shaped slope panel and two guide rails. The two guide rails are fixedly connected to the assembly frame. A slide rail is slidably connected in the guide rail. A removal rod is fixedly connected to one side of the slide rail. The removal rod applies pressure to the connecting plate backward, causing the limiting rod to disengage from the limiting opening and limiting hole. A handle is fixedly connected to the front of the two slide rails, and a molding die is installed between the two slide rails. The molding die contains the sheet material to be extruded, and the flexible pad is used to seal the top of the molding die.

[0012] Preferably, the molding die has two positioning grooves on its upper part, and the size of the positioning rod is adapted to the size of the positioning groove.

[0013] Preferably, a sealing ring is sealed in the molding die, the sealing ring is fixedly connected to the push plate, a return spring is fixedly connected between the push plate and the bottom wall of the molding die, a push rod is fixedly connected below the push plate, the push rod passes downward through the molding die and is fixed to the traveling wheel, the traveling wheel rolls on the arc-shaped slope panel, and the arc-shaped slope panel is fixedly connected to the assembly frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The flexible extrusion component can be linked with the drive component to achieve independent movement of the cap removal component, enabling the cap removal component to combine the upper die cap with the forming die. After the flexible extrusion component extrudes and forms the sheet metal, it performs a reset action. At this time, the drive component and the cap removal component can be linked to separate the upper die cap from the forming die. This design adopts an automatic combination die structure, eliminating the need for tedious manual assembly, significantly reducing workload and improving production efficiency. Furthermore, the cap removal component keeps the upper die cap in a continuously pressed state, resisting external vibration interference and preventing the upper die cap from loosening and creating gaps. At the same time, a flexible pad is added to the upper die cap to achieve flexible positioning and maintain a tight fit to the sheet metal surface, further filling the gap between the upper die cap and the forming die, eliminating sheet metal positioning deviations caused by gaps, and ensuring accurate sheet metal positioning. The side handle of the molding component ensures standardized operation, allowing the molding die and flexible stamping component to be separated. At this time, the traveling wheels rise along the curved slope panel, applying an upward pushing force to the push plate to achieve safe and automatic demolding. After the product is removed, the limiting component can automatically lock the drive component and the cap removal component to prevent the flexible stamping component from accidentally starting the stamping action, thus eliminating stamping accidents caused by misoperation from the source. After the material is picked up and unloaded, the mechanism automatically unlocks without affecting the subsequent stamping process. The entire locking and unlocking process is completed automatically without additional manual operation, which not only ensures the personal safety of the operators but also improves the standardization and safety of the process operation. The flexible stamping component, in conjunction with the drive component and the capping component, can automatically combine and press against the forming component, providing a stable foundation for flexible positioning. This also prevents uneven stress on the flexible positioning material and positioning failure caused by loosening of the forming mold. After the product is formed, the flexible component resets, and the forming component can be moved to perform demolding. At the same time, the limiting component can automatically lock the drive component and the capping component. This method provides safety assurance for the disassembly and assembly of the forming mold, the handling of sheet metal, and the flexible positioning operation. By working together, the precision of flexible positioning and forming mold combination is achieved. This improves production efficiency and sheet metal forming accuracy while ensuring operational safety. It is suitable for the flexible positioning requirements of various stamped sheet metals and provides reliable process support for large-scale, high-precision sheet metal processing.

Detailed Implementation

[0017] 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.

[0018] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0019] Example 1: Refer to Figures 1-7 A flexible positioning process for extruded sheet metal is disclosed, which utilizes a flexible positioning device for the extruded sheet metal. The flexible positioning device includes a flexible positioning mechanism 100, which comprises an assembly frame 101. A flexible extrusion assembly 102, a limiting assembly 104, and a forming assembly 103 are mounted on the assembly frame 101. The flexible extrusion assembly 102 includes a stamping device 1021 and an upper die end cap 1023. The stamping device 1021 is mounted on the assembly frame 101. A mounting plate 1022 is installed at one end of the mounting plate 1021. Ball end sliding parts 1025 are fixedly connected to both sides of the mounting plate 1022. A punching head 1024 is fixedly connected to the bottom of the mounting plate 1022. The punching head 1024 passes through the upper mold end cover 1023. A flexible pad 1027 and two positioning rods 1026 are fixedly connected to the bottom of the upper mold end cover 1023. The material is squeezed into the forming mold 1034 through the flexible pad 1027, thereby achieving flexible positioning and reducing gaps. Both sides of the flexible extrusion assembly 102 are provided with a drive assembly 106 and a cap removal assembly 105. The drive assembly 106 includes a rotating shaft 1063, which is rotatably mounted on the assembly frame 101 via bearings. The rotating shaft 1063 can be kept in stable rotation by the bearings, thereby enabling stable transmission between the driving gear 1061 and the driven gear 1051. The driving gear 1061 is installed at the top of the rotating shaft 1063. A limit hole 1065 is formed on the rotating shaft 1063, and a sleeve 1066 is fitted on the rotating shaft 1063. By sliding the sleeve 1066 on the rotating shaft 1063, the movement of the sleeve 1066 can ensure... The upper die end cap 1023 moves smoothly up and down, while also allowing the rotating shaft 1063 to maintain its rotational movement. The sleeve 1066 is installed on the upper die end cap 1023. The rotating shaft 1063 is also provided with a spiral groove 1064 and two vertical grooves 1062. The two vertical grooves 1062 are connected to the upper and lower ends of the spiral groove 1064. The vertical grooves 1062 ensure the sliding of the ball end sliding part 1025, allowing the extrusion head 1024 to move smoothly. This prevents the upper die end cap 1023 from being pressed against the forming die 1034, which would prevent the extrusion head 1024 from being unable to perform the extrusion forming operation on the sheet metal, thus preventing the ball end from sliding. Part 1025 can slide in the spiral groove 1064 and the vertical groove 1062. Through the arc surface of the spiral groove 1064, the ball end sliding part 1025 can slide and cooperate with the arc surface of the spiral groove 1064, thereby enabling the rotation of the rotating shaft 1063, ensuring operational continuity, reducing investment in drive equipment, and lowering costs. Secondly, the ball end sliding part 1025 sliding in the vertical groove 1062 can act as a limit, ensuring the smooth movement of the mounting plate 1022 and the punch head 1024. The cap removal assembly 105 includes a screw 1052, which is rotated via bearings. Mounted on the assembly frame 101, the screw 1052 has a driven gear 1051 installed at its top end. The driven gear 1051 meshes with the driving gear 1061. A limit port 1053 is opened on the screw 1052. A nut 1054 is threadedly connected to the screw 1052. The nut 1054 is installed on the upper die end cover 1023. Through the threaded transmission between the screw 1052 and the nut 1054, the upper die end cover 1023 can be pressed tightly onto the forming die 1034. The screw 1052 and the nut 1054 are automatically locked, which can effectively prevent loosening and ensure stable stamping and forming of the sheet metal.

[0020] In this embodiment: the stamping equipment 1021 drives the mounting plate 1022 to move downward, enabling the flexible stamping assembly 102 to drive the assembly 106 to achieve the independent movement of the cap removal assembly 105. The cap removal ball end sliding part 1025 enters the spiral groove 1064 through the vertical groove 1062. As the sliding part moves, it cooperates with the spiral groove 1064 to rotate the shaft 1063, causing the drive gear 1061 and driven gear 1051 to drive each other. The screw 1052 drives the nut 1054 to move downward, causing the upper die end cap 1023 to combine downward with the forming die 1034. After the flexible stamping assembly 102 stamps and forms the sheet metal, a reset action is performed. At this time, The linkage drive component 106 and the cap removal component 105 enable the separation of the upper mold end cap 1023 from the forming mold 1034. This design adopts an automatic combination mold structure, eliminating the need for tedious manual assembly, significantly reducing workload and improving production efficiency. Furthermore, the cap removal component 105 keeps the upper mold end cap 1023 in a continuously pressed state, resisting external vibration interference and preventing the upper mold end cap 1023 from loosening and causing gaps. At the same time, a flexible pad 1027 is added to the upper mold end cap 1023 to achieve flexible positioning and maintain a tight fit to the surface of the sheet material, further filling the gap between the upper mold end cap 1023 and the forming mold 1034, eliminating sheet material positioning deviations caused by gaps, and ensuring accurate sheet material positioning.

[0021] Example 2: Refer to Figure 4 and Figures 8-9 A flexible positioning process for extruded sheet metal is disclosed. The flexible positioning device includes a limiting component 104, which includes a fixed plate 1041. Four elastic structures 1042 are fixedly connected to the side of the fixed plate 1041. The elastic structures 1042 are composed of telescopic rods and springs. The elastic reset of the elastic structures 1042 allows the limiting rods 1044 to be engaged with the limiting openings 1053 and limiting holes 1065. This can prevent the flexible extrusion component 102 from being accidentally started by locking the drive component 106 and the cap removal component 105. A connecting plate 1043 is fixedly connected to one end of two elastic structures 1042. Two limiting rods 1044 are fixedly connected to the side of the connecting plate 1043. The size of the limiting rods 1044 is adapted to the size of the limiting openings 1053 and limiting holes 1065. The molding assembly 103 includes an arc-shaped slope panel 1031 and two guide rails 1032. The two guide rails 1032 are fixedly connected to the assembly frame 101. A slide rail 1033 is slidably connected in the guide rails 1032, allowing the molding die 1034 to move stably. The sliding end of the slide rail 1033 ensures that the molding die 1034 and the extrusion head 1024 are precisely aligned. A removal rod 10310 is fixedly connected to one side of the slide rail 1033. 310 applies pressure to the connecting plate 1043 backward, causing the limiting rod 1044 to disengage from the limiting port 1053 and the limiting hole 1065. A handle 1035 is fixedly connected to the front of the two slide rails 1033, allowing for easy movement of the forming mold 1034 and improving operational standardization. The forming mold 1034 is installed between the two slide rails 1033, containing the sheet material to be extruded. A flexible pad 1027 is used to seal the top of the forming mold 1034. Two positioning slots 1039 are provided. The size of the positioning rod 1026 is adapted to the size of the positioning slots 1039. The positioning rod 1026 is precisely inserted into the positioning slots 1039, thereby ensuring the stability of the forming mold 1034 and the stable operation of the stamping process. A sealing ring 1038 is sealed in the forming mold 1034. The sealing ring 1038 increases the sealing performance with the forming mold 1034, ensuring the product molding quality. The sealing ring 1038 is fixedly connected to the push plate 1037. A return spring 10312 is fixedly connected between the push plate 1037 and the bottom wall of the forming mold 1034. The return spring 10312 can drive the push plate 1037 to smoothly complete the reset action downward, ensuring that the subsequent stamping and forming operation is carried out smoothly. A push rod 1036 is fixedly connected below the push plate 1037. The push rod 1036 passes downward through the forming mold 1034 and is fixed to the traveling wheel 10311. The traveling wheel 10311 rolls on the arc-shaped slope panel 1031. The arc-shaped slope panel 1031 is fixedly connected to the assembly frame 101.

[0022] In this embodiment: the side handle 1035 of the molding component 103 ensures standardized operation, allowing the molding die 1034 to be operated separately from the flexible stamping component 102. At this time, the traveling wheel 10311 rises along the arc-shaped slope panel 1031 and applies an upward pushing force to the push plate 1037 through the push rod 1036. The push plate 1037 pushes out the product, realizing a safe and automatic demolding operation. After the product is removed, the elastic structure 1042 drives the limit rod 1044 to reset. The limit rod 1044 is inserted into the limit port 1053, thereby automatically locking the drive component 106 and the cap removal component 105, preventing the flexible stamping component 102 from accidentally starting the stamping action, thus eliminating stamping accidents caused by misoperation from the source. After the material is picked up and unloaded, the mechanism automatically unlocks without affecting the subsequent stamping process. The entire locking and unlocking process is completed automatically without additional manual operation, ensuring the personal safety of the operators and improving the standardization and safety of the process operation.

[0023] Example 3: Reference Figures 1-3 A flexible positioning process for extruded sheet material, the flexible positioning device includes a flexible positioning mechanism 100, the flexible positioning mechanism 100 includes an assembly frame 101, the assembly frame 101 is equipped with a flexible extrusion component 102, a limiting component 104 and a forming component 103, and both sides of the flexible extrusion component 102 are provided with a driving component 106 and a cap removal component 105.

[0024] In this embodiment, the flexible stamping component 102, in conjunction with the drive component 106 and the cap removal component 105, can automatically combine and press against the forming component 103, providing a stable foundation for flexible positioning. This also prevents the forming mold 1034 from becoming loose, which could lead to uneven stress on the flexible positioning material and positioning failure. After the product is formed, the flexible component resets, and the forming component 103 can be moved to perform demolding. At the same time, the limiting component 104 can automatically lock the drive component 106 and the cap removal component 105. This method provides safety assurance for the disassembly and assembly of the forming mold 1034, the handling of sheet metal, and the flexible positioning operation. In this way, the precision of the combination of flexible positioning and the forming mold 1034 is achieved through collaboration. This not only improves production efficiency and sheet metal forming accuracy but also ensures operational safety, adapting to the flexible positioning requirements of various stamped sheet metals and providing reliable process support for large-scale, high-precision sheet metal processing.

[0025] A flexible positioning process for stamped sheet material is as follows: S1. The stamping equipment 1021 pushes the mounting plate 1022 downward, which in turn drives the extrusion head 1024 downward, causing the ball end sliding part 1025 to enter the spiral groove 1064. The spiral groove 1064's arc surface then rotates the shaft 1063. The shaft 1063 drives the drive gear 1061 to rotate, which in turn drives the driven gear 1051, causing the driven gear 1051 to drive the screw 1052 to rotate. The screw 1052 then engages with the nut 1054. The transmission mechanism causes the nut 1054 to drive the upper die end cover 1023 to move downwards. The upper die end cover 1023 drives the positioning rod 1026 into the positioning groove 1039. At the same time, the upper die end cover 1023 drives the flexible pad 1027 to be squeezed into the forming mold 1034 to achieve flexible positioning. After the upper die end cover 1023 is pressed into the forming mold 1034, the ball end sliding part 1025 enters the vertical groove 1062. At this time, the punch head 1024 passes through the upper die end cover 1023 alone and performs punching and forming operations on the sheet metal downwards. S2. After the sheet metal is formed, the flexible extrusion assembly 102 resets upwards and drives the drive assembly 106 and the cap removal assembly 105 to reset upwards, so that the upper mold end cap 1023 separates from the forming mold 1034 and resets. S3. During demolding, the slide rail 1033 is moved by pulling the handle 1035. The slide rail 1033 drives the molding die 1034 and the removal rod 10310 to move. The removal rod 10310 moves away from the connecting plate 1043. At this time, the elastic structure 1042 drives the connecting plate 1043 to reset, so that the limiting rod 1044 is inserted into the limiting port 1053 and the limiting hole 1065, thereby locking the drive assembly 106 and the cap removal assembly 105. At the same time, the movement of the molding die 1034 can move the traveling wheel 10311. The traveling wheel 10311 moves upward to the slope of the arc-shaped slope panel 1031. The push rod 1036 is pushed upwards, and the push plate 1037 is pushed upwards by the push rod 1036, so that the push plate 1037 pushes out the product of the forming mold 1034 to complete the demolding operation. After demolding, the sheet material is placed again, and then the forming mold 1034 is reset. The reset spring 10312 drives the push plate 1037 to complete the reset. At the same time, the slide rail 1033 slides to the end of the guide rail 1032, and the removal rod 10310 pushes the connecting plate 1043 to move, so that the limiting rod 1044 disengages from the limiting port 1053 and the limiting hole 1065. At this time, a new round of sheet material stamping and forming operation can be carried out.

[0026] The above are merely preferred embodiments 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.
