Abstract
Description
Technical Field
[0001] This utility model relates to the field of sheet metal production technology, and in particular to an automatic line drawing and forming post-forming positioning structure. Background Technology
[0002] In recent years, with increasingly fierce competition in the automotive market, major automakers have focused their research and development on the vehicle's body panels and related stamped parts (hereinafter collectively referred to as components) as they develop new models. The requirements for these components are becoming increasingly stringent, with components becoming more complex and requiring higher strength. This presents a significant technical challenge for mold manufacturers. In automated stamping production lines, the product's outline shrinks after the first drawing process, leading to positional deviations in the mold. This can easily damage the robotic arm during part removal and cause misalignment during the second process, potentially damaging the mold. Therefore, this invention provides an automated line drawing system with a post-forming positioning structure. Utility Model Content
[0003] This utility model achieves the above-mentioned objective through the following technical solution: an automatic line drawing and forming post-positioning structure, including a lower template, an upper forming die, and a workpiece. A heightening frame is installed at the top of the lower template, and a lower die base is installed at the top of the heightening frame. A pressure ring is provided at the top of the lower die base, and a pressure insert is installed at the top of the pressure ring. The top of the pressure insert contacts the bottom end of the workpiece. A positioning forming punch is provided at the top of the pressure insert, and its bottom end penetrates the bottom end of the pressure ring. A pad is installed at the top of the lower die base, and a nitrogen spring is installed at the top of the lower template. The output end of the nitrogen spring penetrates the top of the lower die base. A groove adapted to the positioning forming punch is opened at the bottom end of the upper forming die. A cavity is opened inside the pressure ring, and a reset mechanism for resetting the positioning forming punch is installed inside the cavity.
[0004] Preferably, the pad is located at the bottom end of the positioning and forming punch.
[0005] Preferably, a wear-resistant plate is installed on the outer side of the pressure ring, and a guide leg is slidably connected to one side of the wear-resistant plate. The bottom end of the cavity guide leg is fixedly connected to the top end of the lower mold base.
[0006] Preferably, a groove is provided on the outer side of the pressure ring, and a limit hook is slidably connected to the inner side of the groove. The bottom end of the limit hook is fixedly connected to the top end of the lower mold base.
[0007] Preferably, the reset mechanism includes a reset spring, the bottom end of which is fixedly connected to the bottom end of the cavity, a limit ring is fitted on the outer side of the positioning and forming punch, and the top end of the reset spring is fixedly connected to the bottom end of the limit ring.
[0008] Preferably, the top end of the limiting ring is in contact with the top end of the cavity.
[0009] Preferably, the top of the positioning and forming punch is arc-shaped.
[0010] The beneficial effects of this utility model are as follows: The automatic drawing line adds a positioning structure after forming. A positioning forming punch is provided at the top of the pressure ring. After the upper die forming die is pressed down, the pressure ring, pressure ring insert, and positioning forming punch move downwards together. At this time, the positioning forming punch slowly approaches the pad block. When it contacts the pad block, the positioning forming punch stops moving, while the pressure ring and pressure ring insert continue to move downwards. The cooperation between the positioning forming punch and the punch groove allows the workpiece to slowly form a positioning groove. A nitrogen spring is installed at the top of the lower die platen, ensuring that the pressure ring and pressure ring insert automatically reset after the upper die forming die rises. The pad block, located at the bottom of the positioning forming punch, provides support and buffering. When the positioning forming punch moves downwards to the bottom... When in use, the pad can withstand the impact force of the positioning and forming punch, preventing direct collision between the positioning and forming punch and components such as the lower template, thus avoiding damage. A guide leg is slidably connected to one side of the wear-resistant plate to prevent the guide leg from scratching the outer side of the pressure ring. A limit hook is slidably connected to the inner side of the slide groove to limit the pressure ring after it is lifted. The automatic reset of the positioning and forming punch after it is pressed down is achieved by setting a return spring and a limit ring. The top of the positioning and forming punch is arc-shaped, which can reduce the impact force on the workpiece surface, avoid local deformation or scratches on the workpiece, and make it easier for the punch to cut into the workpiece for forming operations, ensuring forming quality. This utility model can effectively assist in the precise positioning of products, reduce the cost of subsequent mold maintenance, and has high practical value. Attached Figure Description

[0017] The present invention will be further described in detail below with reference to specific embodiments.
[0018] Example:
[0019] See Figures 1-4 This utility model provides a technical solution: an automatic line drawing and forming post-positioning structure, including a lower template 100, an upper forming die 105, and a workpiece 112. A lifting frame 101 is installed at the top of the lower template 100, and a lower die base 102 is installed at the top of the lifting frame 101. A pressure ring 104 is provided at the top of the lower die base 102, and a pressure insert 108 is installed at the top of the pressure ring 104. The top of the pressure insert 108 contacts the bottom of the workpiece 112. A positioning forming punch 109 is provided at the top of the pressure insert 108, and its bottom end penetrates the bottom end of the pressure ring 104. A pad 111 is installed at the top of the lower die base 102. A nitrogen spring 103 is installed at the top of the lower template 100, and the output end of the nitrogen spring 103 penetrates the top of the lower die base 102. A groove 1050 adapted to the positioning forming punch 109 is opened at the bottom of the upper forming die 105. 1. The pressure ring 104 has a cavity 10402 inside. A reset mechanism 110 for resetting the positioning forming punch 109 is installed inside the cavity 10402. The positioning forming punch 109 is provided at the top of the pressure ring 108. After the upper die forming male 105 is pressed down, the pressure ring 104, the pressure ring 108, and the positioning forming punch 109 move downward together. At this time, the positioning forming punch 109 slowly approaches the pad 111. When it contacts the pad 111, the positioning forming punch 109 stops moving. The pressure ring 104 and the pressure ring 108 continue to move downward. The cooperation between the positioning forming punch 109 and the punch groove 10501 makes the workpiece 111 slowly form a positioning groove. A nitrogen spring 103 is installed at the top of the lower template 100 to realize that the pressure ring 104 and the pressure ring 108 automatically reset after the upper die forming male 105 is formed and raised.
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-4 The pad 111 is located at the bottom end of the positioning and forming punch 109. A wear-resistant plate 106 is installed on the outer side of the pressure ring 104. A guide leg 107 is slidably connected to one side of the wear-resistant plate 106. The bottom end of the guide leg 107 in the cavity 10402 is fixedly connected to the top end of the lower die base 102. A slide groove 10401 is opened on the outer side of the pressure ring 104. A limit hook 113 is slidably connected to the inner side of the slide groove 10401. The bottom end of the limit hook 113 is fixedly connected to the top end of the lower die base 102. The pad 111 is located at the bottom end of the positioning and forming punch 109. The bottom of 109 serves as a support and buffer. When the positioning and forming punch 109 moves downward to the bottom position, the pad block 111 can withstand the impact force of the positioning and forming punch 109, preventing the positioning and forming punch 109 from directly colliding with components such as the lower template 102 and causing damage. A guide leg 107 is slidably connected to one side of the wear-resistant plate 106 to prevent the guide leg 107 from scratching the outer side of the pressure ring 104. A limit hook 113 is slidably connected to the inner side of the slide groove 10401 to achieve the limit after the pressure ring 104 is lifted.
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-4The reset mechanism 110 includes a reset spring 11001, the bottom end of which is fixedly connected to the bottom end of the cavity 10402. A limit ring 11002 is fitted on the outer side of the positioning and forming punch 109. The top end of the reset spring 11001 is fixedly connected to the bottom end of the limit ring 11002. The top end of the limit ring 11002 is in contact with the top end of the cavity 10402. The top end of the positioning and forming punch 109 is arc-shaped. Through the setting of the reset spring 11001 and the limit ring 11002, the positioning and forming punch 109 can be automatically reset after being pressed down. The arc-shaped top end of the positioning and forming punch 109 can reduce the impact force on the surface of the workpiece, avoid local deformation or scratches of the workpiece, make it easier for the punch to cut into the workpiece for forming operation, and ensure the forming quality.
[0024] Specifically, the working principle of this automatic line drawing and forming post-forming positioning structure is as follows: During use, a positioning forming punch 109 is provided at the top of the pressure ring 108. After the upper die forming male 105 is pressed down, the pressure ring 104, pressure ring 108, and positioning forming punch 109 move downwards together. At this time, the positioning forming punch 109 slowly approaches the pad block 111. When it contacts the pad block 111, the positioning forming punch 109 stops moving, while the pressure ring 104 and pressure ring 108 continue to move downwards. The cooperation between the positioning forming punch 109 and the punch groove 10501 causes the workpiece 111 to slowly form a positioning groove. A nitrogen spring 103 is installed at the top of the lower die plate 100, ensuring that the pressure ring 104 and pressure ring 108 automatically reset after the upper die forming male 105 rises during forming. The pad block 111, located at the bottom of the positioning forming punch 109, provides support and cushioning. When the positioning forming punch 109... When the punch moves downward to the bottom position, the pad 111 can withstand the impact force of the positioning punch 109, avoiding direct collision between the positioning punch 109 and components such as the lower template 102, which would cause damage. A guide leg 107 is slidably connected to one side of the wear-resistant plate 106 to prevent the guide leg 107 from scratching the outer side of the pressure ring 104. A limit hook 113 is slidably connected to the inner side of the slide groove 10401 to limit the pressure ring 104 after it is lifted. The automatic reset of the positioning punch 109 after it is pressed down is achieved by setting the return spring 11001 and the limit ring 11002. The top of the positioning punch 109 is arc-shaped, which can reduce the impact force on the surface of the workpiece and avoid local deformation or scratches of the workpiece. This makes it easier for the punch to cut into the workpiece for forming operations and ensures the forming quality. This utility model can effectively assist in the precise positioning of the product and reduce the cost of subsequent mold maintenance, and has high practical value.
[0025] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
