[0048] like Figures 1 to 8 The diagram provided for this embodiment is a schematic diagram in some embodiments.

[0049] In some embodiments, automotive sheet metal stamping dies can be used for the production of various types of automotive sheet metal parts, such as body panels, frame structural parts, and chassis components. Body panels may include, but are not limited to, engine hoods, trunk lids, doors, and fenders. In the embodiment of support mounting bracket 1 in the figure, the stamping die is used as an example to produce automotive door sheet metal parts. Of course, other types of automotive sheet metal stamping dies can also adopt similar structures, which will not be elaborated further below.

[0050] It is understood that the support mounting bracket 1 in the figure only schematically shows some of the components included in the automotive sheet metal stamping die. The actual shape, size, position, and construction of these components are not limited by the support mounting bracket 1 in the figure. For example, the specific shapes of the upper and lower dies of the die will be designed according to the shape of the sheet metal part to be produced. Automotive sheet metal stamping dies that facilitate blanking may also include more or fewer components than the support mounting bracket 1 in the figure to meet the specific requirements of different production scenarios.

[0051] It should be noted that the specific shape and position of the component shown in the figure as support mounting bracket 1 are for illustrative purposes only and can be adjusted according to production needs. Support mounting bracket 1 is fixed to the ground on site using expansion bolts provided on site. For example, the fixing method of support mounting bracket 1 is not limited to expansion bolts. In some embodiments, welding or anchor bolts can also be used for fixing, as long as stable support can be achieved. The shape and size of stamping template 23 can be designed according to the contour of the sheet metal parts to be produced (such as engine hoods and fenders) and are not fixed.

[0052] In some embodiments, a support mounting frame 1 is included, a stamping die body 2 is disposed on the lower side of the support mounting frame 1, a base 3 is disposed on the lower side of the stamping die body 2, and a material feeding and pushing adjustment unit 4 is disposed on the inner side of the base 3. The material feeding and pushing adjustment unit 4 includes a material feeding component 41, a material pushing component 42 and a material outlet adjustment component 43, and the material feeding component 41 is disposed between the material pushing component 42 and the material outlet adjustment component 43.

[0053] It should be noted that the stamping die body 2 may include a drive cylinder 21, which is a driving force used to move the stamping die body 2 downward. The stamping die body 2 may also include a stamping cylinder 22 and a stamping template 23. The shape and size of the stamping template 23 can be adjusted according to actual needs. The stamping cylinder 22 is the upper die that drives the stamping template 23 to stamp the sheet metal.

[0054] Specifically, the stamping cylinder 22 is installed below the support mounting bracket 1, which supports the device. The stamping cylinder 22 is installed on the lower side of the stamping die body 2 so as to stamp the sheet metal through the stamping template 23.

[0055] In this embodiment, the stamping die body 2 can be made of high-strength metal materials, such as carbon structural steel or alloy structural steel. These materials have good mechanical properties and can withstand the pressure and impact during the stamping process, ensuring the stability and durability of the equipment.

[0056] In some embodiments, the material dropping assembly 41 includes a material dropping template 411 that slides on the base 3. The material dropping assembly 41 includes a tilting movement unit and a material dropping reset unit. The material dropping reset unit includes a first guide slide rod 412 disposed on the lower side of the material dropping template 411, and a material dropping reset spring 413 is sleeved on the outer side of the first guide slide rod 412.

[0057] It should be noted that the first guide slide rod 412 is slidably connected to the inner side of the cylinder provided on the base 3, and the two ends of the material dropping reset spring 413 are respectively fixedly set on the lower side of the material dropping template 411 and the upper side of the cylinder.

[0058] In some embodiments, the tilting moving unit includes connecting sliding holes 414 disposed on both sides of the blanking template 411, a pressure plate 415 slidingly attached to the inner side of the connecting sliding holes 414, and a ball bearing 416 arranged on one side of the pressure plate 415, and a first guide groove 417 disposed on the side of the pressure plate 415 away from the ball bearing 416.

[0059] Specifically, the ball bearing 416 rolls and slides against the inner side of the connecting slide hole 414, and the pressure plate 415 slides on the first guide groove 417 via a rod provided on the side away from the ball bearing 416.

[0060] Among them, a sliding rod and a connecting cylinder for limiting and guiding are provided between the blanking template 411 and the base 3. The pressure plate 415 is provided with two sets distributed on both sides of the blanking template 411. The upper part of the first guide slide 417 is inclined and the lower part of the first guide slide 417 is vertical.

[0061] With this configuration, the blanking template 411 is slidably connected to the base 3, allowing it to move downwards after stamping and disengage the sheet metal part from the stamping die. The first guide slide 412 and the blanking return spring 413 ensure the smooth movement and automatic reset function of the blanking template 411, guaranteeing the accuracy and repeatability of the blanking action. The pressure plate 415 and ball bearings 416 allow the blanking template 411 to flexibly adjust its position during movement, adapting to sheet metal parts of different shapes and sizes, ensuring a smooth and unobstructed blanking process.

[0062] In some embodiments, the feeding assembly 42 includes a driven feeding unit and a feeding reset unit. The driven feeding unit includes a wedge block 421, and a first connecting plate 423 is provided on the lower side of the wedge block 421. A baffle 422 is provided on the upper side of the wedge block 421. A connecting groove 424 is provided on the first connecting plate 423. The feeding assembly 42 also includes a connecting rod 425, and the lower end of the connecting rod 425 is slidably connected to the inner side of the connecting groove 424. A push plate 426 is fixedly provided on the upper end of the connecting rod 425.

[0063] Specifically, a sliding shaft is provided at the connection between the connecting rod 425 and the push plate 426. The baffle 422 is L-shaped and is located on one side of the wedge block 421. The upper surface of the wedge block 421 is inclined. The wedge block 421 and the baffle 422 are symmetrically distributed on the upper side of the first connecting plate 423. The middle part of the connecting groove 424 is hollow, and the lower side of the connecting groove 424 is fixed to the upper side of the first connecting plate 423. The sliding shaft at the lower end of the connecting rod 425 is slidably connected to the hollow inner part of the connecting groove 424, and the upper end of the connecting rod 425 is fixed to one side of the push plate 426.

[0064] In some embodiments, the pusher reset unit includes a connecting telescopic rod 427 located at the middle position of the lower side of the baffle 422, and a pusher reset spring 428 is sleeved on the upper side of the connecting telescopic rod 427. The pusher reset unit also includes a second guide groove 429 installed inside the base 3, and the sliding shaft between the connecting rod 425 and the pusher plate 426 is slidably connected to the inner side of the second guide groove 429.

[0065] Specifically, the sliding shaft at the connection point of the connecting rod 425 and the push plate 426 is slidably connected to the second guide groove 429. The upper part of the second guide groove 429 is inclined, and the lower part of the second guide groove 429 is vertical. The two ends of the pusher reset spring 428 are respectively fixedly connected to the middle position of the lower side of the baffle 422 and the connecting telescopic rod 427.

[0066] The pusher assembly 42 further pushes the sheet metal parts on the blanking template 411 to the discharge port. The special design of the wedge block 421 and the baffle 422 allows the pusher assembly 42 to adaptively adjust according to the position and shape of the sheet metal parts. The connecting rod 425 and the push plate 426, through the cooperation of the sliding shaft and the guide groove, realize the tilting and vertical movement of the push plate 426, ensuring that the sheet metal parts can be accurately pushed to the discharge port, avoiding jamming and accumulation of sheet metal parts during the blanking process, and improving production efficiency.

[0067] In some embodiments, the discharge port adjustment assembly 43 includes an adjustment partition 431 disposed inside the discharge port on one side of the base 3, and a second connecting plate 432 is arranged on the lower side of the adjustment partition 431. The two sides of the adjustment partition 431 are slidably connected to a second guide slide rod 433 disposed inside the base 3, and an adjustment reset spring 434 is sleeved on the outer side of the second guide slide rod 433.

[0068] Specifically, the adjusting partition 431 is slidably connected to the second guide slide rod 433, and the two ends of the adjusting reset spring 434 are respectively fixedly connected to the lower side of the adjusting partition 431 and the inner side of the base 3.

[0069] It should be noted that the lower side of one side of the pressure plate 415 is attached to and slides against the upper side of the wedge block 421, and the lower side of the pressure plate 415 is on the upper side of the second connecting plate 432, and one end of the pressure plate 415 is attached to and slides against the lower side of the baffle 422.

[0070] The discharge port adjustment component 43 changes the size of the discharge port by adjusting the movement of the baffle 431 to accommodate sheet metal parts of different thicknesses. The cooperation between the baffle 431, the second guide slide rod 433, and the adjustment reset spring 434 enables the discharge port to be adjusted quickly and accurately, ensuring that the sheet metal parts can pass through the discharge port smoothly, facilitating collection and subsequent processing by staff.

[0071] It should be noted that the core function of the automotive sheet metal stamping die for easy blanking is to realize the stamping and blanking adjustment of automotive sheet metal parts. Specifically, the support mounting bracket 1 provides fixed support for the entire device and is fixed to the ground by expansion bolts to ensure stability during the stamping process; the stamping die body 2 is the core execution component, and the drive cylinder 21 provides driving force for the downward movement of the stamping die body 2. The stamping cylinder 22 drives the stamping template 23 to complete the stamping operation of the sheet metal, and the shape of the stamping template 23 is... The dimensions can be adjusted according to the requirements of the sheet metal parts to be processed; the base 3 is used to place the sheet metal to be stamped, and the blanking and pushing adjustment unit 4 is responsible for the blanking and discharge adjustment. The blanking component 41 realizes blanking guidance through the blanking template 411, the first guide slide rod 412 and the blanking reset spring 413. The pushing component 42 completes the pushing of the stamped sheet metal with the help of wedge block 421, push plate 426 and other structures. The discharge port adjustment component 43 adapts to the discharge requirements of sheet metal of different thicknesses through adjusting partition 431, second guide slide rod 433 and other structures.

[0072] It should be noted that the combination of the above components enables a continuous operation from sheet metal placement and stamping to blanking. This description only takes the production of automotive door sheet metal parts as an example, and similar functional structures can be used for the production of other types of sheet metal parts.

[0073] It should be noted that the "first state" mentioned in the text can be understood as the initial position of the component when it is not working (such as the position of the blanking template 411 when it is not under pressure), and the "second state" is the position when it is working (such as the position of the blanking template 411 after it is under pressure and moves down). The transition of each component from the first state to the second state is achieved by the driving force of the drive cylinder 21 and the stamping cylinder 22. The reset spring assists in returning it to the initial state to ensure the continuity of the cyclic operation.

[0074] Understandably, this easy-to-unload automotive sheet metal stamping die achieves multiple practical effects through the coordinated action of its various components. First, the stamping die body 2 is made of high-strength materials such as carbon structural steel and alloy structural steel, which can withstand the pressure and impact during the stamping process, ensuring long-term stable operation of the equipment and extending its service life. Second, the design of the blanking and pushing adjustment unit 4 integrates blanking, pushing, and outlet adjustment. Thin sheet metal parts can be automatically ejected by the push plate 426, while thick sheet metal parts can be manually removed by adjusting the partition 431 to move down and expand the outlet, adapting to the production needs of sheet metal parts of different thicknesses and improving operational flexibility. Third, the fixed setting of the support mounting bracket 1 and the cooperation of various guide slides (first guide slide 412, second guide slide 433, etc.) and return springs (blanking return spring 413, pushing return spring 428, etc.) ensure precise movement and reliable reset of each component, reducing operational errors and improving stamping and blanking efficiency.

[0075] In use, firstly, the staff places the sheet metal to be stamped on the upper side of the base 3. By starting the drive cylinder 21, the stamping die body 2 moves downward, and at the same time, the stamping template 23 moves downward, thus pressing the sheet metal. By starting the stamping cylinder 22, the stamping template 23 continues to move downward to perform the stamping operation on the sheet metal, and the lower part of the stamping template 23 extends beyond the lower side of the stamping die body 2.

[0076] The stamped sheet metal moves downwards, and the blanking template 411 moves downwards. At the same time, the first guide slide rod 412 slides downwards inside the cylinder, and the blanking return spring 413 is pressed down. This causes the pressure plate 415 to move downwards. After moving downwards for a certain distance, the pressure plate 415 presses down the wedge block 421, causing the first connecting plate 423 to move downwards. At the same time, the connecting telescopic rod 427 retracts, and the pusher return spring 428 is pressed down. This also causes the connecting slide groove 424 to move downwards, and the stamped sheet metal moves downwards following the blanking template 411.

[0077] The push plate 426 is driven to move downward by the connecting rod 425. The push plate 426 slides on the upper part of the second guide groove 429 through the sliding shaft between the connecting rod 425 and the push plate 426. The upper part of the second guide groove 429 is inclined, so the push plate 426 can move downward at an angle. At the same time, the lower end of the connecting rod 425 slides laterally on the connecting groove 424, so the push plate 426 can move downward at an angle. Thus, the push plate 426 pushes the stamped sheet metal onto the blanking template 411.

[0078] When the sliding shaft between the connecting rod 425 and the push plate 426 moves to the corner of the inclined and vertical parts of the second guide groove 429, and the lower end of the connecting rod 425 moves to the other end of the connecting groove 424, and one side of the pressure plate 415 separates from the baffle 422 and is on the inclined surface of the wedge block 421, and the push plate 426 moves to a distance above the blanking template 411 and fits against the sheet metal side, the lowering speed of the blanking assembly 41 is relatively fast, so that the push plate 426 can move too fast, and the sheet metal can be popped out, so that the sheet metal can be moved to the upper side of the adjusting partition 431, and then collected and placed by the staff.

[0079] After the blanking is completed, the stamping cylinder 22 drives the stamping template 23 to move upward, which in turn causes the blanking template 411 to move upward. At the same time, the blanking template 411 is driven to move upward by the elastic force of the blanking reset spring 413. Meanwhile, the first connecting plate 423 is driven to move upward by the elastic force of the pusher reset spring 428. At the same time, the pusher plate 426 is also lifted. Meanwhile, the pressure plate 415 is moved back to the inside of the baffle 422 to facilitate the next stamping blanking operation.

[0080] When the sheet metal is too thick, the stamping template 23 stamps again, and the push plate 426 moves to the position when stamping thin sheet metal. At the same time, the first connecting plate 423 returns to its original position by the elastic force of the push return spring 428. Meanwhile, the pressure plate 415 continues to tilt and move on the first guide slide 417. At the same time, the pressure plate 415 moves inside the connecting slide hole 414 through the ball 416, so that the other side of the pressure plate 415 moves to the upper side of the second connecting plate 432, which drives the adjusting partition 431 to move downward. The adjusting partition 431 slides downward on the second guide slide 433, and at the same time, it squeezes the adjusting return spring 434. The size of the discharge hole can be adjusted by adjusting the descent of the adjusting partition 431, and then the workers can manually remove the thick sheet metal.

[0081] Once the material is removed, the adjusting partition 431 can be returned to its original position by the elastic force of the second guide slide rod 433 and the pusher reset spring 428. At the same time, the dropping template 411 returns to its original position, and the pressure plate 415 returns to the inside of the baffle 422 by the inclined setting of the first guide slide groove 417.

[0082] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power.
