[0030] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0031] Reference Figures 1 to 3, which is the first embodiment of the utility model, proposes a stamping auxiliary blanking device, which is used to assist the stamping device 1 in cutting off the waste at the edge of the sheet metal part. The stamping device 1 has a lower mold 3, and the stamping device 1 has a plurality of discharge grooves 101. The plurality of discharge grooves 101 are located around the lower mold 3 and are used to collect waste, including a toggle rod 13, and a toggle part 131 is provided at one end of the toggle rod 13. There are a plurality of toggle rods 13, and the other ends of the plurality of toggle rods 13 are all swingably set on the stamping device 1. After the toggle rod 13 swings, the toggle part 131 is located above the discharge groove 101, and the toggle part 131 is used to toggle the waste.
[0032] In this embodiment, a punching-assisted blanking device is designed to address the problem in related art of the inability to quickly remove scrap removed from sheet metal parts by a stamping device. The punching device 1 is used to perform stamping and trimming operations on automotive sheet metal parts. The lower die 3 within the punching device is surrounded by several discharge chutes 101. Multiple toggle levers 13 are provided, each with a toggle portion 131 at one end. The other ends of these toggle levers 13 are pivotally mounted on the punching device 1 via a specific connection.
[0033] In actual application, a rotation axis can be set at a specific position on the punching device 1, and the toggle lever 13 is connected to the punching device 1 via the rotation axis, so that the toggle lever 13 can swing around the rotation axis. When it is necessary to clean the waste, the toggle lever 13 swings, so that the toggle portion 131 moves to the top of the discharge chute 101.
[0034] The advantage is that, by providing a swingable toggle lever 13, waste can be quickly transferred to the discharge chute 101 after stamping is completed, thereby improving the efficiency of waste removal and reducing the time and labor intensity of manual cleaning. Timely waste removal can prevent waste accumulation from affecting the normal operation of the stamping device 1, thereby ensuring production continuity. The device has a relatively simple structure, is easy to install and maintain, and has low cost. It can be adjusted and optimized according to different stamping devices 1 and production requirements, and is suitable for the stamping production of various automotive sheet metal parts.
[0035] Furthermore, a plurality of toggle rods 13 are arranged at intervals.
[0036] In this embodiment, the plurality of toggle rods 13 are spaced apart. For example, the plurality of toggle rods 13 are evenly distributed around the punching device 1, with a certain distance between adjacent toggle rods 13. In this way, during operation, each toggle rod 13 has an independent swinging space and will not interfere with each other.
[0037] When the stamping is completed and the waste needs to be cleaned, each toggle rod 13 can be independently swung according to the actual situation to move the waste into the discharge chute 101. Due to the interval arrangement, even when processing large-sized waste, it is ensured that the toggle rod 13 has enough space to move the waste effectively.
[0038] The advantage is that the spaced-apart toggle levers 13 do not interfere with each other during their swinging, ensuring that each toggle lever 13 functions properly and improving the reliability of waste removal. The spaced-apart toggle levers 13 allow for more flexible adjustment and operation for waste of varying shapes and sizes, improving the device's ability to handle a wide variety of waste materials. The spacing creates a certain amount of space between the toggle levers 13, facilitating inspection, repair, and replacement, and reducing maintenance costs.
[0039] Furthermore, it also includes a mounting rod 14 , which is a plurality of mounting rods 14 . The mounting rods 14 are arranged on the punching device 1 , and the plurality of toggle rods 13 are swingably arranged on the punching device 1 through the mounting rods 14 .
[0040] In this embodiment, there are a plurality of mounting rods 14 mounted on the punching device 1. The mounting rods 14 can be fixed to a specific position of the punching device 1 by welding, bolting, etc. A plurality of toggle rods 13 are swingably mounted on the punching device 1 via the mounting rods 14.
[0041] Specifically, one end of the toggle lever 13 is provided with a connection hole, through which the mounting rod 14 passes. This allows the toggle lever 13 to swing around the mounting rod 14. When waste material needs to be cleaned after the punching operation of the punching device 1, the toggle lever 13 can be flexibly swung with the support of the mounting rod 14 to push the waste material into the discharge chute 101.
[0042] The advantage is that mounting rod 14 provides stable support for toggle rod 13, ensuring that toggle rod 13 does not wobble or deflect during swinging, thereby improving the accuracy and efficiency of waste material removal. The provision of mounting rod 14 facilitates the installation of toggle rod 13 on punching device 1, and the position and angle of toggle rod 13 can be adjusted according to actual needs, thereby improving the adaptability of the device. The presence of mounting rod 14 increases the structural strength of the entire blanking device, enabling it to withstand the vibration and impact forces generated during the punching process, thereby extending the service life of the device.
[0043] Furthermore, the toggle rod 13 has a second abutment surface 132. After the punching device 1 slides downward, the punching device 1 abuts against the second abutment surface 132, driving the toggle rod 13 to swing. It also includes a third elastic member 15. The two ends of the third elastic member 15 are respectively hinged to the mounting rod 14 and the toggle rod 13, and are used to provide the toggle rod 13 with force to move the waste material after the punching device 1 slides upward, so that the toggle rod 13 is reset.
[0044] In this embodiment, the toggle lever 13 has a second abutting surface 132 . When the punching device 1 slides downward to perform a punching operation, a specific portion of the punching device 1 abuts against the second abutting surface 132 of the toggle lever 13 .
[0045] During the descent of the upper die 2 of the punching device 1, a protruding portion of its side surface gradually approaches and eventually contacts the second abutting surface 132 of the toggle rod 13. As the upper die 2 continues to descend, this abutting force drives the toggle rod 13 to swing around the mounting rod 14.
[0046] A third elastic member 15 is also provided, its two ends hinged to the mounting rod 14 and the toggle rod 13, respectively. When the punching device 1 slides upward and withdraws, the third elastic member 15 begins to function. The contraction of the third elastic member 15 provides the toggle rod 13 with a force that pushes the waste material, causing it to return to its original position.
[0047] The third elastic member 15 can be a spring, one end of which is connected to the mounting rod 14 through a hinge, and the other end is connected to the toggle rod 13. When the punching device 1 moves upward, the spring contracts and pulls the toggle rod 13 back to its initial position, preparing for the next waste cleaning.
[0048] The advantage is that the waste cleaning action is automatically triggered by the contact between the punching device 1 and the toggle rod 13, without the need for an additional power source, thereby improving the automation level and working efficiency of the equipment. The third elastic member 15 can ensure that the toggle rod 13 is accurately reset after the punching device 1 completes the punching, providing reliable preparation for the next waste cleaning and ensuring the continuous operation of the equipment. The movement of the punching device 1 is used to drive the toggle rod 13, without the need for additional energy consumption, thus reducing production costs. The presence of the third elastic member 15 makes the movement of the toggle rod 13 smoother, reduces equipment damage caused by sudden impact force, and improves the stability and reliability of the equipment.
[0049] Furthermore, it also includes a cutting knife 16 , and there are a plurality of cutting knives 16 . The cutting knives 16 are arranged in the discharge trough 101 and are spaced apart from the mounting rod 14 .
[0050] In this embodiment, a number of cutting knives 16 are evenly distributed in the discharge trough 101 and are spaced apart from the toggle rod 13. When the stamping operation is performed, as the upper mold 2 is pressed downward, the waste material at the edge of the sheet metal part comes into contact with the cutting knives 16 while being cut off. The blades of these cutting knives 16 are sharp and strong and can withstand the pressure and friction during the stamping process. During the cutting process, after the waste material is cut into small pieces, it is easier to be toggled by the subsequent toggle rod 13. When the toggle rod 13 swings, its toggle part 131 is accurately located above the discharge trough 101, and the waste material cut into small pieces can be easily toggled into the discharge trough 101, so that the waste material can smoothly fall into the discharge trough 101 for collection and processing.
[0051] In actual production, when the punching device 1 is activated, the upper die 2 moves downward to punch and trim the sheet metal part. The waste material is removed and cut into small pieces by the cutter 16. Subsequently, the upper die 2 slides upward, and the toggle lever 13 pushed by the upper die 2 during its descent returns to its original position under the action of the third elastic member 15, pushing the small pieces of waste material into the discharge chute 101.
[0052] The advantage is that the waste is cut into small pieces by the cutting blade 16 during stamping, greatly optimizing the waste handling process. Small pieces of waste are not only easier to move with the toggle lever 13, but also more easily fall into the discharge chute 101, improving waste removal efficiency. The cut small pieces of waste are less likely to clog the discharge chute 101, ensuring smooth discharge and continuous operation of the equipment, reducing downtime and maintenance costs caused by poor discharge.
[0053] Furthermore, the mounting rod 14 has a limiting surface 141 . After one end of the moving rod 13 moves the waste material, the moving rod 13 abuts against the limiting surface 141 .
[0054] In this embodiment, the mounting rod 14 has a limiting surface. When one end of the moving rod 13 moves the waste material, the moving rod 13 abuts against the limiting surface of the mounting rod 14.
[0055] A plane is designed as a limit surface at a specific part of the mounting rod 14. When the toggle rod 13 swings to clean the waste, as the swing angle increases, when the toggle rod 13 completes the toggle operation on the waste, it will gradually approach the mounting rod 14 and eventually contact the limit surface on the mounting rod 14.
[0056] The advantage is that the presence of the limiting surface precisely controls the swing range of the toggle lever 13, ensuring that the toggle lever 13 performs the waste cleaning operation within the appropriate angle and preventing excessive or insufficient swinging that could affect the waste cleaning effect. By limiting the swing range of the toggle lever 13, the entire waste cleaning process is more stable and reliable, reducing the possibility of accidents caused by unstable swinging of the toggle lever 13. The limiting surface prevents excessive swinging of the toggle lever 13 from damaging other equipment components, thereby extending the service life of the equipment.
[0057] Furthermore, both ends of the third elastic member 15 have hanging rings 151, and also include a hanging rod 17, the hanging rod 17 has a hanging part 171, and there are two hanging rods 17, the two hanging rods 17 are respectively arranged on the mounting rod 14 and the toggle rod 13, and the two hanging rings 151 are respectively hung with the two hanging parts 171.
[0058] In this embodiment, the third elastic member 15 has a hook 151 at each end. A hook rod 17 has a hooking portion 171. Two hook rods 17 are provided, one mounted on the mounting rod 14 and the other on the toggle rod 13. One hook rod 17 is mounted on the mounting rod 14, positioned to facilitate connection with the third elastic member 15, and secured by welding or bolts. The other hook rod 17 is mounted on the toggle rod 13, also using a suitable securing method.
[0059] The two hanging rings 151 are respectively connected to the two hanging portions 171. For example, when the third elastic member 15 needs to be installed, the hanging ring 151 at one end of the third elastic member 15 is hung on the hanging portion 171 of the hanging rod 17 on the installation rod 14, and the hanging ring 151 at the other end is hung on the hanging portion 171 of the hanging rod 17 on the toggle rod 13. In this way, the third elastic member 15 can play a role in the operation of the punching device 1 and provide a reset force for the toggle rod 13.
[0060] The advantage is that the design of the hanging ring 151 and the hook portion 171 makes the installation and replacement of the third elastic member 15 very convenient. The operator can quickly connect the third elastic member 15 to the mounting rod 14 and the toggle rod 13, improving the maintenance efficiency of the equipment. Because the third elastic member 15 is more convenient to install and replace, it can be replaced promptly when it ages or becomes damaged, avoiding damage to other equipment components caused by the failure of the elastic member, thereby increasing the service life of the equipment.
[0061] Furthermore, both ends of the hanging rod 17 have a hanging portion 171, and the two hanging rods 17 are both set on the installation rod 14 and the toggle rod 13. The third elastic member 15 is used in pairs, and the paired hanging rings 151 are respectively hung on the two ends of the two hanging rods 17.
[0062] In this embodiment, both ends of the hanging rod 17 have a hooking portion 171. Both hanging rods 17 are installed through the mounting rod 14 and the toggle rod 13. The third elastic members 15 are used in pairs, and the hanging rings 151 of the paired third elastic members 15 are respectively hooked to the hooking portions 171 at both ends of the two hanging rods 17.
[0063] For example, the hanging rod 17 is a slender cylindrical rod, slightly longer than the combined thickness of the mounting rod 14 and the toggle rod 13. During installation, the hanging rod 17 is passed through the holes in the mounting rod 14 and the toggle rod 13, exposing the connecting portions 171 at both ends of the hanging rod 17. The two third elastic members 15 are then attached to the ends of the two hanging rods 17, respectively. This arrangement allows the force of the third elastic members 15 to be more evenly distributed on the toggle rod 13, improving the stability of the toggle rod 13's return to its original position.
[0064] The advantage is that using the third elastic member 15 in pairs and hanging them at both ends of the hanging rod 17 can provide a more balanced and stable reset force for the toggle rod 13, ensuring that the toggle rod 13 can accurately return to its original position after the waste is cleaned, ready for the next cleaning.
[0065] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
