Description

Technical Field

[0001] The present invention relates to the technical field of stamping equipment, and specifically to a metal sheet stamping device for mechanical engineering. Background Art

[0002] In the field of mechanical manufacturing, the stamping process of metal sheets is a key technology for producing parts with complex geometric shapes, and is widely used in the manufacturing of products such as automobile bodies, electronic device casings, and building components. Traditional stamping equipment usually uses fixed molds and a single stamping head, and is only suitable for the production of large quantities of single parts, making it difficult to meet the requirements of modern manufacturing for flexible production of multiple varieties and small batches.

[0003] At present, some stamping equipment on the market attempts to adapt to the processing of different parts by replacing molds or adjusting stamping parameters, but there are still the following technical bottlenecks: Low mold replacement efficiency: The traditional method relies on manual disassembly and assembly of molds, which is time-consuming and laborious, and it is difficult to ensure the adjustment accuracy, affecting the production rhythm. Unintelligent stamping stroke adjustment: Different molds require different stamping depths. Traditional equipment needs to be adjusted manually, which easily leads to uneven stamping pressure and affects the forming quality.

[0004] Insufficient automation: Loading and unloading mostly rely on manual labor or independent manipulators, and the equipment integration degree is low, making it difficult to achieve efficient continuous production. Equipment stability needs to be improved: During high-speed stamping, the insufficient rigidity of the traditional structure easily causes vibration, resulting in dimensional deviation of parts or increased mold wear. The existing technology still has difficulty in balancing functions such as rapid switching of multiple molds, adaptive stamping adjustment, and automated loading and unloading. Therefore, there is an urgent need for an integrated and intelligent stamping device to improve production efficiency, reduce labor costs, and adapt to diverse production requirements.

A signal transmission line 9 is arranged between the ranging sensor 8 and the processing control box 10.

[0033] The driving component includes a transmission box 15 fixedly arranged at the bottom of the top plate 30. A driving motor 39 is fixedly connected to the top plate 30. The end of the output shaft of the driving motor 39 is fixedly connected to the mounting column 4.

The end of the transmission column 17 is fixedly connected to the rotating shaft of the transmission bevel gear 27. A transmission housing 18 is fixedly connected to the inner wall of the mounting rod 2.

[0035] The feeding component includes a rotating column 19 rotatably arranged outside the transmission housing 18. The end of the rotating column 19 is fixedly connected to the rotating shaft of the driven wheel 29. A rotating roller 38 is fixedly sleeved on the rotating column 19. An adsorption head 37 is fixedly connected to the side wall of the rotating roller 38. Stabilizing rods 31 are fixedly connected to both sides of the mounting rod 2. The stabilizing rods 31 are fixedly connected to the bottom plate 1.

[0036] During the implementation of the present invention, the operator can place the same or different molds 20 on the bearing plate 3 according to the type of stamping. If different molds 20 are placed, the operator needs to rotate the threaded rod 5 under different molds 20 to drive the end 33 to move and adjust the height of the end 33. Then, rotate the adjusting rod 7 to drive the pressing block 25 to move to fix the mold 20. Under the action of the electric hydraulic telescopic rod 12, the telescopic column 22 on one side of the mounting arm 14 can be driven to move downward by the pressing rod 13. The stamping head 21 at the bottom of the telescopic column 22 will contact the metal plate, and then the stamping of the metal plate can be realized under the action of the mold 20. If continuous stamping with different types of molds 20 is carried out, under the action of the driving motor 39, the mounting column 4 can be driven to rotate. The bearing plate 3 on the mounting column 4 rotates and can drive the rotating disk 16 to rotate at the same time, realizing the simultaneous replacement of the mold 20 and the stamping head 21, improving the efficiency of stamping construction for different types of parts. At the same time, when the bearing plate 3 rotates, since the heights of the ends 33 under different molds 20 are different, when the end 33 contacts the ranging sensor 8, the signals received by the ranging sensor 8 are also different. Because different molds 20 have different stamping formations during stamping, through this method, under the action of the processing control box 10, the electric hydraulic telescopic rod 12 can be controlled to move downward to different heights. This method can ensure continuous stamping of the plate while flexibly adjusting the stamping stroke, realizing efficient continuous stamping of different parts. At the same time, under the action of the rotating column 19, the rotating roller 38 can be driven to rotate, and the plate is released or adsorbed through the adsorption head 37 to realize automatic loading and unloading, further improving the stamping efficiency.
