Description

Technical Field

[0001] The present application relates to the technical field of casting processing, and in particular to a casting system for arc-shaped copper-aluminum alloy plates. Background Art

[0002] Aluminum alloy materials have always been the first choice and most widely used material in the building curtain wall industry because of their advantages such as strong plasticity and good corrosion resistance. With the continuous pursuit of architectural style, there are higher requirements for the use of aluminum appearance. As for the casting process, the more complex the appearance of the copper-aluminum alloy plate, the more difficult it is to cast, the higher the cost, and the longer the casting cycle. Especially for the shape of special-shaped hyperboloids, it is a high-difficulty category in the casting profession.

[0003] like Figure 1 As shown, for the above-mentioned special-shaped hyperbolic product 8, the production method in the prior art is to first cast a copper-aluminum alloy plate with a size similar to that of the product 8 in a casting mold, then directly place the copper-aluminum alloy plate on the stamping mold, and use the stamping mold to stamp the copper-aluminum alloy plate into a specified shape (i.e., a special-shaped hyperbolic surface), and then cut the surface of the pressed product 8 to complete the production of the product 8.

[0004] However, when the product 8 is cast in the above manner, since the shape and size of the cast copper-aluminum alloy plate are relatively rough, the relatively rough copper-aluminum alloy plate is subsequently directly stamped into the shape of the product 8 through a mold, which easily causes the thickness of the stamped product 8 to be uneven, that is, the main material is concentrated in the bending and deformation parts of the product 8, which leads to the need for more precise cutting processing of the product 8 later. Since the shape of the product 8 is a special-shaped hyperbolic design, it takes a long time to perform more precise grinding on the curved surface, and the processing process is also more cumbersome, which increases the casting cycle of the product 8 and reduces the production efficiency of the product 8. Utility Model Content

[0005] In order to achieve the purpose of ensuring the processing quality of copper-aluminum alloy plates by pre-processing the copper-aluminum alloy flat plates to ensure that there will be no uneven product thickness after the copper-aluminum alloy plates are stamped into shape, thereby improving the production efficiency of the products, the present application provides a curved copper-aluminum alloy plate casting system.

[0006] The present application provides a curved copper-aluminum alloy plate casting system, which adopts the following technical solution:

[0007] A casting system for an arc-shaped copper-aluminum alloy plate comprises a frame on which is provided a plate casting module for casting a flat plate, a plate cutting module for cutting the flat plate, a plate stamping module for stamping the cut flat plate into a special-shaped hyperbolic surface, and a force detection module for detecting the force condition of the flat plate during the stamping process, wherein the force detection module is arranged on the plate stamping module.

[0008] By adopting the above technical scheme, when in use, the specified flat plate structure, that is, the arc plate shape of the product in the flattened state, is first cast through the plate casting module, and then the flat plate is cut into the specified shape through the plate cutting module. During the cutting process, the area and shape of the flat plate cut off are obtained by the product stamping forming simulation experiment, and then the flat plate is punched into the hyperbolic special-shaped structure of the product through the plate stamping module. During the stamping process, the force condition of the flat plate is detected by the force detection module, so that the staff can make fine adjustments to the plate cutting module in real time to ensure the quality of the product after production. At the same time, compared with the existing technology, the overall process does not require the post-grinding of the plate to ensure the consistency of the thickness of the plate, thereby saving the processing process of the plate and improving the production efficiency of the plate.

[0009] Preferably, the plate casting module comprises a casting mold fixed on a frame and a heat dissipation device arranged on the frame, and the heat dissipation device is located between the casting mold and the plate cutting module.

[0010] By adopting the above technical solution, the corresponding casting mold is selected according to the requirements of the arc-shaped specifications and dimensions of the product, so as to cast a flat plate of the product unfolded size model with corresponding specifications and dimensions, and the flat plate is heat-dissipated by the heat dissipation device, so as to facilitate the subsequent processing of the flat plate.

[0011] Preferably, a first robotic arm for transferring products is provided between the heat dissipation device and the casting mold.

[0012] By adopting the above technical solution, since the temperature of the flat plate just cast is relatively high during use, the cast flat plate is transported to the heat dissipation device by the first robot arm to be fanned, which is convenient for use.

[0013] Preferably, the plate cutting module includes a first cutting device for cutting the planar end of the flat plate, a second cutting device for cutting the curved end of the flat plate, and a second robotic arm for transferring the plate on the first cutting device to the second cutting device.

[0015] Preferably, the first cutting device includes a first cutting operating table fixed on the frame, a first cutting knife installed on the first cutting operating table, and a first fixing component arranged on the first cutting operating table for fixing a flat plate.

[0017] Preferably, the first fixing assembly includes a support block mounted on the first cutting operation table and a first pressing plate arranged on the first cutting operation table, and the support block is arranged in an arc surface at one end away from the first cutting operation table.

[0018] By adopting the above technical solution, the flat plate is supported by the support block during use, and the four sides of the flat plate are fixed by the first pressing plate, thereby avoiding the problem of the flat plate shaking when being cut, causing the cutting path of the flat plate to deviate.

[0019] Preferably, the second cutting device includes a second cutting operating table fixed on the frame, a second cutting knife installed on the second cutting operating table, and a second fixing component arranged on the second cutting operating table for fixing the flat plate.

[0020] By adopting the above technical solution, the flat plate that has been cut initially is fixed and limited by the second fixing component, and then the flat plate is cut for the second time by the second cutting knife, so that the flat plate is cut into a specified shape, and the overall process is simple and convenient.

[0021] Preferably, the second fixing assembly includes a plurality of second pressing plates arranged on the cutting operating table, and the plurality of second pressing plates are spaced apart and distributed around the flat plate.

[0022] By adopting the above technical solution, the second pressing plate is used to fix the four sides of the flat plate, so that the flat plate is fixed and limited on the second cutting operating table.

[0023] Preferably, the plate stamping module comprises an upper die and a lower die mounted on the frame, the curvature of the pressing surfaces on the upper die and the lower die matches the curvature of the plate surface of the product, and the force detection module is arranged on the lower die.

[0024] By adopting the above technical scheme, the curvature of the pressing surface on the upper mold and the lower mold used for pressing the flat plate is consistent with the curvature requirement of the plate surface of the hyperbolic curved plate, that is, the curvature of the pressing surface on the upper mold and the lower mold is set and controlled by the plate surface extension effect and the pressing rebound coefficient generated by the flat plate under pressure, thereby ensuring that after the flat plate is stamped by the upper mold and the lower mold, the thickness of the stamped product is consistent, thereby ensuring that the quality of the stamped product meets the standards.

[0025] Preferably, a third robotic arm is disposed on the frame, and the third robotic arm is disposed between the sheet metal stamping module and the sheet metal cutting module.

[0026] By adopting the above technical solution, the cut flat plate is transported to the plate stamping module by the third robot arm for stamping, and the stamped products are unloaded at the same time, making the overall processing process more convenient.

The lower die 42 is fixedly connected to the frame 1 by bolts, and the upper die 41 is slidably connected to the frame 1, and the upper die 41 is located directly above the lower die 42. A hydraulic cylinder 43 is also provided on the frame 1, and the cylinder body of the hydraulic cylinder 43 is fixed to the frame 1 by bolts, and the piston rod of the hydraulic cylinder 43 is bolted to the upper die 41. When in use, the cut flat sheet 9 is placed on the lower die 42 through the third robotic arm 7, and the upper die 41 is driven to slide downward by the contraction of the piston rod of the hydraulic cylinder 43, so that the flat sheet 9 is pressed into a specified shape through the upper die 41.

[0054] Reference Figure 8It should be noted that the curvature and direction of the pressing surface of the upper mold 41 and the lower mold 42 are required to be consistent with the curvature and direction of the plate surface of the product 8, i.e., the hyperbolic curved plate.

[0057] The implementation principle of the embodiment of the present application is as follows: when in use, a flat plate 9 of a specified shape is first cast through the casting mold 21, and then the flat plate 9 is transferred to the setting position of the heat dissipation device 22 by the first mechanical arm 6, and the flat plate 9 is cooled by the heat dissipation device 22. After the cooling of the flat plate 9 is completed, the staff can transport the flat plate 9 to the first cutting operation table 311, and fix the flat plate 9 through the first fixing component 313, and then cut the long side of the flat plate 9 into a specified shape through the first cutting knife 312, open the first fixing component 313, and then transport the flat plate 9 on the first cutting operation table 311 to the second cutting operation table 321 through the second mechanical arm 33, and then fix it through the second fixing component 323. The flat plate 9 is fixed and limited, and the wide side of the flat plate 9 is cut by the second cutting knife 322. After the cutting is completed, the flat plate 9 on the second cutting operating table 321 is transported to the lower mold 42 by the third robot arm 7, and then the upper mold 41 can be driven downward by the hydraulic cylinder 43 to punch the flat plate 9 into a product 8 with a hyperbolic special-shaped structure, thereby completing the processing and production of the product 8. This ensures the quality of the product 8 after forming while reducing the uneven thickness of the product 8 made by directly stamping the plate in the prior art, resulting in the need to grind the product 8 later and wasting time and cost on the product 8, thereby achieving the purpose of reducing the plate casting cycle and improving the manufacturing efficiency of the product 8, and the overall processing process is simpler and more convenient.
