[0002] As the name implies, stamping dies for automobile parts manufacturing are specially used for stamping process in the production process of automobile parts. Stamping is a processing method that uses a punch and a die to separate or plastically deform materials. It is widely used in the processing of metal sheets. In the automotive industry, a large number of body panels, structural parts, etc. need to be manufactured through stamping process.

[0003] Stamping dies are usually composed of a punch (also called an upper die) and a die (also called a lower die). When working, a metal sheet is placed on the die, and the punch applies pressure from above to make the metal sheet plastically deform or shear according to the shape of the die, thereby forming the required automotive parts.

The mounting holes of the muffler connection flange are used to fix the flange to the adjacent exhaust pipe section or other related components through bolts. These mounting holes are usually processed by stamping. However, when multiple mounting holes are processed at the same time, the flange may be deformed due to excessive stamping. This deformation will not only destroy the shape and structural integrity of the flange, but also affect its connection accuracy with other components, thereby affecting the performance and operational reliability of the automobile exhaust system.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] The present invention will be further described below in conjunction with the embodiments.

[0037] See also Figures 1 to 10 A stamping die for manufacturing automobile parts in this embodiment includes a base 10, a lower mold body 30 is rotatably connected to the top of the base 10, an upper mold body 20 matching the lower mold body 30 is arranged directly above the lower mold body 30, a toggle mechanism 40 for driving the lower mold body 30 to rotate horizontally is arranged on the outside of the lower mold body 30, a positioning mechanism 50 for preventing the workpiece from being offset is arranged inside the lower mold body 30, and an ejection mechanism 60 for conveniently removing the workpiece from the top of the lower mold body 30 is also arranged inside the lower mold body 30.

[0038] The toggling mechanism 40 includes an inclined slot 401 formed on the side surface of the lower die body 30. A vertical slot 402 is also formed on the side surface of the lower die body 30, and the vertical slot 402 communicates with the inclined slot 401. A first rotating rod 403 is rotatably connected to the side surface of the upper die body 20. A cross bar 404 is fixedly connected to the bottom of the first rotating rod 403. A roller 405 is rotatably connected to one end of the cross bar 404 away from the first rotating rod 403. The roller 405 extends into the inclined slot 401 and rolls in the inclined slot 401. An inclined mechanism 70 for assisting the workpiece to separate from the lower die body 30 is provided at the top of the ejecting mechanism 60. A blowing mechanism 80 for removing the debris after stamping the workpiece is provided between the upper die body 20 and the lower die body 30. The inclined slot 401 and the vertical slot 402 can be adjusted according to the number of mounting holes of the stamped flange. When stamping four mounting holes, four groups of inclined slots 401 and vertical slots 402 can be provided, and each inclined slot 401 and vertical slot 402 are sequentially connected end to end. And so on. When stamping five mounting holes, five groups of inclined slots 401 and vertical slots 402 can be provided, and each inclined slot 401 and vertical slot 402 are sequentially connected end to end.

[0039] A tension spring 406 is fixedly connected to the outside of the first rotating rod 403, and the other end of the tension spring 406 is fixedly connected to the side surface of the upper die body 20.

[0040] During specific operation, place the flange workpiece to be stamped on the top of the lower die body 30. After fixing the workpiece by using the positioning mechanism 50, start the downward movement of the upper die body 20 to stamp the workpiece. When the upper die body 20 moves downward, it drives the first rotating rod 403 and the cross bar 404 to move downward synchronously. At this time, the roller 405 moves in the vertical slot 402. When the upper die body 20 moves to the lowest position, under the pulling force of the tension spring 406, the first rotating rod 403 rotates to one side, thereby driving the roller 405 to enter the inclined slot 401 communicating with the vertical slot 402. Then the upper die body 20 moves upward. During the upward movement of the upper die body 20, the roller 405 is driven by the first rotating rod 403 and the cross bar 404 to move from the bottom of the inclined slot 401 to the top of the inclined slot 401 and enter the top of the vertical slot 402. During this process, the rotation of the lower die body 30 is completed, so that the flange workpiece rotates a predetermined angle and enters the next working station, dispersing the punching stress concentration phenomenon and avoiding the flange diameter reduction deformation caused by the superposition of multi-directional instantaneous loads.

[0041] The positioning mechanism 50 includes a mounting rod 501 vertically penetrating the lower die body 30, and the mounting rod 501 is fixedly connected to the lower die body 30. A pull rod 502 is vertically slidably connected in the cavity of the mounting rod 501. Movable blocks 503 are symmetrically slidably connected to the side surface of the mounting rod 501. A connecting rod 504 is rotatably connected to the side surface of each movable block 503. One end of the connecting rod 504 away from the movable block 503 is rotatably connected to the top of the pull rod 502.

[0042] The bottom of the pull rod 502 is rotatably connected to a hinge seat 505. The outside of the hinge seat 505 is rotatably connected to a lever 506. One end of the lever 506 is rotatably connected to the bottom of the base 10, and the other end of the lever 506 extends to the side of the base 10.

[0043] During specific operation, before placing the flange workpiece on the lower die body 30, first, lift one end of the lever 506 upward, so that the lever 506 pushes the pull rod 502 to move upward. The upward-moving pull rod 502 drives the two moving blocks 503 to approach each other through the connecting rod 504. Then, place the flange workpiece on the lower die body 30, so that the through hole in the middle of the workpiece is sleeved outside the mounting rod 501. After that, release the lever 506. Under the elastic force of the first spring 603 in the ejecting mechanism 60, the lever 506 rotates downward, and the downward-rotating lever 506 drives the pull rod 502 to move downward synchronously. The pull rod 502 drives the two moving blocks 503 to move away from each other through the connecting rod 504. The two moving blocks 503 moving away from each other abut against the inside of the through hole of the workpiece, thereby realizing the fixation of the flange workpiece, and can quickly and accurately position to the predetermined position of the workpiece, not only reducing the position adjustment time required after each rotation, but also ensuring the stability of the flange during the rotation and stamping operations.

[0044] The ejecting mechanism 60 includes a plurality of accommodation holes 601 vertically opened in the middle of the lower die body 30. A ejector rod 602 is slidably connected inside each accommodation hole 601, and the bottom of the ejector rod 602 extends to the bottom of the lower die body 30. The bottoms of the plurality of ejector rods 602 are fixedly connected to a ring 604, and the bottom of the ring 604 is slidably abutted against the upper surface of the lever 506. Four ejector rods 602 are provided, and the four ejector rods 602 are arranged in a rectangle on the lower die body 30.

[0045] A first spring 603 is slidably sleeved outside each ejector rod 602, and the first spring 603 is located outside the ejector rod 602 between the lower die body 30 and the ring 604.

[0046] During specific operation, after stamping the flange workpiece, push the lever 506 upward. The lever 506 pushes the pull rod 502 to move upward. The upward-moving pull rod 502 drives the two moving blocks 503 to approach each other through the connecting rod 504, thereby releasing the fixation of the moving blocks 503 on the workpiece. During the process of the lever 506 being pushed upward, the lever 506 synchronously pushes the ring 604 upward, and the ring 604 synchronously drives the four ejector rods 602 to move upward, so as to move the four ejector rods 602 from the accommodation holes 601 to the top of the lower die body 30, and eject the stamped workpiece from the surface of the lower die body 30, reducing the time required for the traditional demoulding process. The automatic ejection process also reduces the risk of damage to the surface of the workpiece, and helps to maintain the consistency and stability of the product quality.

[0047] The tilting mechanism 70 includes a receiving groove 701 formed at the top of the ejector rod 602. A movable rod 702 is slidably connected inside the receiving groove 701. A second spring 703 is fixedly connected to the bottom of the movable rod 702. One end of the second spring 703 away from the movable rod 702 is fixedly connected to the bottom of the receiving groove 701. The bottom of the movable rod 702 is in a "convex" shape. There are two sets of tilting mechanisms 70, and the two sets of tilting mechanisms 70 are located at the tops of two ejector rods 602 on the same side.

[0048] A second rotating rod 704 is arranged in the side cavity of the receiving groove 701. The second rotating rod 704 is rotatably connected to the ejector rod 602. A hemispherical stopper 705 is fixedly connected to one side of the second rotating rod 704, and the stopper 705 blocks the "convex" structure at the bottom of the movable rod 702. A triangular block 706 is fixedly connected to the side of the second rotating rod 704 away from the stopper 705, and a through hole for the triangular block 706 to pass through is formed in the side of the ejector rod 602. A metal reed 707 is arranged on the side of the second rotating rod 704 close to the stopper 705. One end of the metal reed 707 is fixedly connected to the ejector rod 602, and the side of the metal reed 707 abuts against the side of the second rotating rod 704.

[0049] During specific operation, after the ejector rod 602 rises to the top from the receiving hole 601, under the push of the metal reed 707, the triangular block 706 on the side of the second rotating rod 704 moves out of the through hole on the side of the ejector rod 602 to the outside of the ejector rod 602. At this time, the stopper 705 disengages from the "convex" structure of the movable rod 702. Then, the second spring 703 pushes the movable rod 702 to move upward. The upwardly moving movable rod 702 can be used to extend the height of the ejector rod 602. Cooperating with the other two ejector rods 602 whose heights are not extended, the workpiece is in an inclined state, and the inclined workpiece slides off the lower die body 30, which is convenient for quickly removing the workpiece and further improving the workpiece processing speed.

[0050] After the workpiece is removed from the lower die body 30, then place the flange workpiece on the lower die body 30, press down the workpiece to make the movable rod 702 reset along the receiving groove 701, so that the workpiece returns to the horizontal state on the tops of the four ejector rods 602. Then, lift one end of the lever 506 upward, so that the lever 506 pushes the pull rod 502 to move upward. The upwardly moving pull rod 502 drives the two moving blocks 503 to approach each other through the connecting rod 504 to fix the new workpiece.

[0051] The blowing mechanism 80 includes a cylindrical airbag 801 fixedly connected to the top of the lower die body 30. A hose 803 is fixedly connected to the top of the airbag 801. One end of the hose 803 away from the airbag 801 is fixedly connected to an air outlet 802, and the air outlet 802 is fixedly connected to the side of the upper die body 20.

[0052] The blowing mechanism 80 also includes a guide rod 804 fixedly connected to the top of the lower mold body 30, the guide rod 804 is slidably connected to a movable plate 805 on the outside, and the movable plate 805 is fixedly connected to the top of the airbag 801, the guide rod 804 is slidably sleeved on the outside with a third spring 806, the top of the movable plate 805 is fixedly connected to an extrusion rod 807, and the side of the extrusion rod 807 is fixedly connected to the side of the upper mold body 20.

[0053] During specific operation, when the upper mold body 20 moves downward, the upper mold body 20 drives the movable plate 805 to move downward synchronously along the guide rod 804 through the extrusion rod 807. When the movable plate 805 moves downward, the airbag 801 can be compressed, and the third spring 806 is compressed at the same time. After the airbag 801 is compressed, the air is ejected from the air outlet 802 through the hose 803. The ejected high-speed airflow washes away the debris on the surface of the workpiece, reducing the stamping flaws or defects of the workpiece caused by residues, and can also prevent these debris from causing damage to the mold, thereby extending the service life of the mold. The blowing process realized by the work of the mold reduces the need for manual cleaning, thereby saving time cost. When the upper mold body 20 moves upward, the upper mold body 20 drives the movable plate 805 to move upward synchronously along the guide rod 804 through the extrusion rod 807. When the movable plate 805 moves upward, the airbag 801 can be driven to recover. At the same time, the compressed third spring 806 can also assist the movable plate 805 to move upward.

[0054] Working principle:

[0055] When stamping the workpiece, the upper mold body 20 drives the flange workpiece to rotate through the toggle mechanism 40. Each stamping only completes the forming of a single hole. Then the flange workpiece rotates a predetermined angle to enter the next workstation. During the rotation, the positioning mechanism 50 is used to fix the workpiece to ensure the stability of the flange during rotation and stamping operations. After the stamping is completed, the positioning mechanism 50 is released from the workpiece, and the ejection mechanism 60 is used to lift the workpiece from the surface of the lower mold body 30. Then the tilting mechanism 70 assists in sliding the workpiece off the lower mold body 30. During each downward movement of the upper mold body 20 for stamping, the blowing mechanism 80 will clean the surface of the workpiece to reduce stamping flaws or defects in the workpiece caused by residues, and to prevent these debris from damaging the mold, thereby extending the service life of the mold.
