Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment, specifically a sheet metal curved surface shaping device with uniform pressure. Background Technology

[0002] In the processing and forming of sheet metal, especially for the shaping of curved components, heating and pressurization are typically required. Existing shaping devices generally use heated molds to hot-press the sheet metal. However, in practical applications, these conventional devices have some technical limitations.

[0003] Firstly, regarding heat conduction, the gaps between the sheet surface and the mold heating surface, which are difficult to fully adhere, affect the uniformity of heat transfer. This can easily lead to uneven heating of different parts of the sheet, with some areas potentially suffering from insufficient heating and poor shaping, or damaging the material due to localized overheating, thus affecting the overall quality of the final product.

[0004] Secondly, in terms of heat control, static heating methods are prone to causing local heat accumulation and hot spots in the closed or semi-closed space between the mold and the sheet material. This is also a factor that leads to uneven heating of the sheet material and affects the shaping effect.

[0005] To address this, we propose a device for shaping curved surfaces of sheet metal under uniform pressure. Utility Model Content

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figs. 1-3 In this embodiment of the utility model, a sheet metal curved surface shaping device with uniform pressure includes a body 1, a worktable 2, a top plate 8, a movable pressing mechanism, and a heating shaping mechanism.

[0024] Support feet 10 are fixedly connected to the four corners of the lower surface of the machine body 1. A workbench 2 is fixedly connected to the upper surface of the machine body 1, and a lower mold 11 is fixedly connected to the upper surface of the workbench 2. Limiting rods 5 are fixedly connected to the four corners of the upper surface of the workbench 2. The top of the limiting rods 5 is fixedly connected to the lower surface of the top plate 8. A movable pressing mechanism is provided below the top plate 8. The movable pressing mechanism includes a hydraulic cylinder 9, a movable plate 6, and an upper mold 4. The hydraulic cylinder 9 is fixedly connected to the upper surface of the top plate 8. The hydraulic cylinder 9 is connected to an external hydraulic system through a hydraulic pipe. The output end of the hydraulic cylinder 9 passes through the inner wall of the top plate 8 and is fixedly connected to the movable plate 6. The upper mold 4 is fixedly connected to the lower surface of the movable plate 6.

[0025] It should be noted that the hydraulic cylinder 9, through the transmission of hydraulic oil, drives the moving plate 6 and the upper mold 4 to move vertically downward, evenly pressing the surface of the plate and making it fit tightly against the lower mold 11, thereby achieving uniform pressure and achieving the effect of pressing and shaping the plate.

[0026] The lower mold 11 and the upper mold 4 are equipped with heating and shaping mechanisms, which include an upper heating plate 3 and a lower heating plate 12. The upper heating plate 3 is fixedly connected to the outer surface of the upper mold 4, and the lower heating plate 12 is connected to the lower mold 11 through a vibration bonding mechanism. The vibration bonding mechanism includes a connecting plate 14, a limiting plate 13, a sliding rod 18, and a spring 17. The upper surface of the lower heating plate 12 is fixedly connected to both sides of the connecting plate 14, and the upper surface of the connecting plate 14 has multiple evenly distributed through slots. A sliding rod 18 is slidably connected in the through groove. The top end of the sliding rod 18 extends above the connecting plate 14 and is fixedly connected to the limiting plate 13. The bottom end of the sliding rod 18 is fixedly connected to the upper surface of the lower mold 11. A spring 17 is threaded through the outer side of the bottom end of the sliding rod 18. The two ends of the spring 17 are respectively connected to the lower mold 11 and the connecting plate 14. A vibration motor 16 is fixedly connected to the upper surface of the connecting plate 14. A blower 15 is fixedly connected to the upper surface of the connecting plate 14, and the air outlet of the blower 15 is set directly opposite the lower heating plate 12.

[0027] It should be noted that the heating and shaping mechanism heats the sheet material through the upper heating plate 3 and the lower heating plate 12 to reduce the difficulty of forming the sheet material, thereby improving the accuracy and quality of the sheet material shaping. During the heating process, the vibration motor 16 is started, which drives the lower heating plate 12 to vibrate through the connecting plate 14. This vibration design helps to enhance the physical contact between the heating plate and the sheet material, thereby improving the heat conduction efficiency and improving the uniformity of heating of the sheet material, so as to achieve a better shaping effect.

[0028] It should be noted that the exhaust fan 15 is designed to promote hot air circulation in the heating area, thereby avoiding localized overheating caused by concentrated heat and ensuring a more uniform heating process. This positively impacts the heating quality and shaping effect of the sheet material. Furthermore, the airflow generated by the exhaust fan 15 also provides some cooling to the heating plate, helping to extend its service life.

[0029] The movable plate 6 passes through the limiting rod 5 and is slidably connected to it, ensuring the stability and accuracy of the movable plate 6 in the vertical direction, so that the upper mold 4 can evenly press the plate and avoid uneven pressing caused by the tilting or shaking of the movable plate 6.

[0030] A transparent baffle 7 is fixedly connected to the upper surface of the machine body 1. The baffle 7 serves as a transparent protective barrier, which can prevent debris, dust and other splashes generated during the processing from flying out and falling into the working environment, keeping the working area clean, reducing environmental pollution, protecting operators from injury and improving operational safety.

[0031] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
