Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and more specifically to a stamping die for manufacturing precision automotive parts. Background Technology

[0002] Stamping is one of the core processes in modern automobile manufacturing, especially in the production of body structural parts, key chassis components, and increasingly more precision parts such as battery housings and motor brackets for new energy vehicles. Stamping relies on stamping dies to plastically deform or separate metal sheets under the action of a press, thereby efficiently and in large quantities obtaining parts with complex shapes and consistent dimensions. Its high efficiency, high consistency and excellent material utilization make it the cornerstone of automobile mass production.

[0003] Nowadays, when precision automotive parts are produced by stamping, due to the high dimensional requirements of these parts, they are generally processed and shaped using a strip feed method across multiple die steps. However, when processing under multiple dies, impurities generated during the previous die's processing or external dust falling onto the strip feed can cause dimensional errors in the next die's processing. Furthermore, when the stamping die moves upward after pressing down, the upper die may lift the strip feed, affecting processing accuracy. Currently, it is not possible to effectively fix the strip feed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a stamping die for the production of precision automotive parts, so as to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a stamping die for the production of precision automotive parts, comprising a fixed base, a lower stamping die fixedly connected to the top of the fixed base, a fixed plate provided on the square of the lower stamping die, a press fixedly connected to the top of the fixed plate, a dust removal mechanism fixedly connected to the side of the press, the dust removal mechanism being located inside the fixed plate, and limit mechanisms fixedly connected to both sides of the top of the fixed base; the dust removal mechanism includes a servo motor that can provide power, a threaded rod fixedly connected to the side of the servo motor, two output bevel teeth fixedly connected to the side of the threaded rod, connecting bevel teeth meshing at the bottom ends of the two output bevel teeth, a synchronous gear fixedly connected to the bottom end of the connecting bevel teeth, a speed-increasing gear meshing at the side of the synchronous gear, a transmission gear fixedly connected to the top of the speed-increasing gear, a fan gear meshing at the side of the transmission gear, a fan shaft fixedly connected inside the fan gear, and a blade assembly fixedly connected to the bottom end of the fan shaft.

[0006] Furthermore, there are three lower stamping dies and three upper stamping dies, and the positions of the three lower stamping dies and the three upper stamping dies correspond one-to-one. The two air outlet positions of the dust removal mechanism are located in the middle of every two upper stamping dies.

[0007] Furthermore, the root circle diameter of the synchronous gear is three times that of the speed-increasing gear, and the root circle diameter of the transmission gear is three times that of the fan gear.

[0008] Furthermore, the dust removal mechanism includes a limiting rod that passes through a fixed plate, and a support plate is movably connected to the side of the connecting bevel teeth, which supports the connecting bevel teeth.

[0009] Furthermore, the limiting mechanism includes a fixing screw for fixing, a threaded cylinder is threadedly connected to the top end of the fixing screw, a handwheel is fixedly connected to the top end of the threaded cylinder, and an upper limiting ring and a lower limiting ring are fixedly connected to the side of the threaded cylinder from top to bottom.

[0010] Furthermore, a limiting plate is provided between the upper limiting ring and the lower limiting ring, and limiting grooves adapted to the threaded cylinder are opened on both sides of the limiting plate, with the threaded cylinder located in the limiting groove of the limiting plate.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model is equipped with a servo motor, a threaded rod, an output bevel gear, and a blade assembly. When the servo motor starts, it drives the threaded rod to rotate. When the threaded rod rotates, it drives the output bevel gear to rotate. The output bevel gear drives the blade assembly to rotate after being transmitted through gears. The blade assembly accelerates when it rotates, thereby increasing the speed of the blade assembly, improving the wind power, and thus improving the cleaning effect on the surface of the discharge belt below, and improving the stamping quality.

[0013] 2. The utility model includes a fixed screw, a threaded cylinder, and a limiting plate. The discharge belt is located below the limiting plate. When the handwheel is turned, the threaded cylinder rotates. When the threaded cylinder rotates, it rotates on the side of the fixed screw, causing the threaded cylinder to move up and down. When the threaded cylinder moves, it drives the lower limiting ring and the upper limiting ring to move. When the lower limiting ring and the upper limiting ring move, they drive the limiting plate to move, so that the limiting plate can press and limit the discharge belt of different heights.

Detailed Implementation

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Reference Figure 1 and Figure 2 This utility model provides a stamping die for the production of precision automotive parts, including a fixed base 1, a lower stamping die 2 fixedly connected to the top of the fixed base 1, a fixed plate 3 provided on the front of the lower stamping die 2, a press 4 fixedly connected to the top of the fixed plate 3, a dust removal mechanism 6 fixedly connected to the side of the press 4, the dust removal mechanism 6 being located inside the fixed plate 3, and a limit mechanism 7 fixedly connected to both sides of the top of the fixed base 1.

[0022] In this embodiment, the application includes a lower stamping die 2 and an upper stamping die 5. Therefore, stamping is performed through multiple steps to improve the processing quality. An exhaust mechanism is provided between every two upper stamping dies 5 to ensure that the surface is sufficiently clean when the next step is performed, thereby improving the processing quality.

[0023] Reference Figure 3 and Figure 4The dust removal mechanism 6 includes a servo motor 601 that provides power. A threaded rod 602 is fixedly connected to the side of the servo motor 601. Two output bevel teeth 604 are fixedly connected to the side of the threaded rod 602. The bottom ends of the two output bevel teeth 604 are meshed with connecting bevel teeth 605. A synchronous gear 606 is fixedly connected to the bottom end of the connecting bevel teeth 605. A speed-increasing gear 607 is meshed to the side of the synchronous gear 606. A transmission gear 608 is fixedly connected to the top of the speed-increasing gear 607. A fan tooth is meshed to the side of the transmission gear 608. The fan gear 609 has a fan shaft 610 fixedly connected inside it. The bottom end of the fan shaft 610 is fixedly connected to a blade assembly 611. The root circle diameter of the synchronous gear 606 is three times that of the root circle diameter of the speed-increasing gear 607. The root circle diameter of the transmission gear 608 is three times that of the root circle diameter of the fan gear 609. The dust removal mechanism 6 includes a limiting rod 603, which passes through the fixing plate 3. A support plate 612 is movably connected to the side of the connecting bevel gear 605, and the support plate 612 supports the connecting bevel gear 605.

[0024] In this embodiment, the servo motor 601 starts and drives the threaded rod 602 to rotate. When the threaded rod 602 rotates, it drives the output bevel gear 604 to rotate. When the output bevel gear 604 rotates, it drives the connecting bevel gear 605 below to rotate. The connecting bevel gear 605 drives the synchronous gear 606 to rotate synchronously. The root circle diameter of the synchronous gear 606 is three times the root circle diameter of the speed-increasing gear 607. Therefore, when the synchronous gear 606 rotates, it causes the speed-increasing gear 607 to rotate faster. When the speed-increasing gear 607 rotates, it drives the transmission gear 608 to rotate synchronously. The root circle diameter of the transmission gear 608 is three times the root circle diameter of the fan gear 609. When the transmission gear 608 rotates synchronously, it drives the fan gear 609 to rotate faster. When the fan gear 609 rotates, it drives the blade group 611 to rotate through the fan shaft 610. When the blade group 611 rotates, it blows air downwards, thereby blowing away impurities above the discharge belt. The support plate 612 supports the connecting bevel gear 605 to ensure the stability of the connecting bevel gear 605 when it rotates.

[0025] Reference Figure 5 The limiting mechanism 7 includes a fixing screw 701 for fixing. The top end of the fixing screw 701 is threadedly connected to a threaded cylinder 702. The top end of the threaded cylinder 702 is fixedly connected to a handwheel 703. The side of the threaded cylinder 702 is fixedly connected from top to bottom to an upper limiting ring 705 and a lower limiting ring 704. A limiting plate 706 is provided between the upper limiting ring 705 and the lower limiting ring 704. Limiting grooves that are adapted to the threaded cylinder 702 are opened on both sides of the limiting plate 706. The threaded cylinder 702 is located in the limiting groove of the limiting plate 706.

[0026] In this embodiment, when the handwheel 703 rotates, it drives the threaded cylinder 702 to rotate. When the threaded cylinder 702 rotates on the side of the fixed screw 701, it moves up and down. When the threaded cylinder 702 moves up and down, it drives the lower limit ring 704 and the upper limit ring 705 to move. When the lower limit ring 704 and the upper limit ring 705 move, they drive the limit plate 706 to move up and down, thereby limiting and pressing the material discharge to ensure that the material discharge strip will not be carried up during the stamping process of this application.

[0027] The working principle of this utility model is as follows: During the stamping operation, the discharge belt moves above the lower stamping die 2. The press 4 controls the upper stamping die 5 to move downward. The downward movement of the upper stamping die 5 causes the upper stamping die 5 to close with the lower stamping die 2, thereby performing the stamping operation. During the stamping operation, the servo motor 601 starts and drives the threaded rod 602 to rotate. When the threaded rod 602 rotates, it drives the output bevel gear 604 to rotate. When the output bevel gear 604 rotates, it drives the connecting bevel gear 605 below to rotate. The connecting bevel gear 605 drives the synchronous gear 606 to rotate synchronously. When the synchronous gear 606 rotates, it causes the speed-increasing gear 607 to rotate faster. When the speed-increasing gear 607 rotates, it drives the transmission gear 608 to rotate synchronously. When the transmission gear 608 rotates synchronously, it drives the fan gear 609 to rotate faster. When the fan gear 609 rotates, it drives the blade group 611 to rotate through the fan shaft 610. When the blade group 611 rotates, it blows air downward, thereby blowing away the impurities above the discharge belt.

[0028] When the discharge belt moves, the handwheel 703 is turned. When the handwheel 703 turns, it drives the threaded cylinder 702 to turn. When the threaded cylinder 702 rotates on the side of the fixed screw 701, it will move up and down. When the threaded cylinder 702 moves up and down, it drives the lower limit ring 704 and the upper limit ring 705 to move. When the lower limit ring 704 and the upper limit ring 705 move, they drive the limit plate 706 to move up and down, thereby limiting and pressing the discharge.

[0029] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
