Description

Technical Field

[0001] The utility model relates to the field of blanking technology, and more specifically, to a blanking device for a spherical protective net. Background Art

[0002] In the production of spherical protective nets, it is necessary to punch out the required shape of 304# stainless steel hexagonal hole plates of a specific thickness. It is necessary to punch out the semicircular spherical edge of the spherical stainless steel hexagonal hole plates, and reserve a specific width of non-construction area at predetermined angles to facilitate later processing into installation edges. The processing technology requirements are relatively high (spherical protective nets such as Figure 5 ).

[0003] It is difficult to accurately punch a spherical surface using traditional punching methods. For example, it is difficult to accurately punch a spherical surface using longitudinal punching in a single direction, and it is difficult to reserve a specific width of non-construction area at a predetermined angle between spherical surfaces. For example, the utility model patent with announcement number CN222220866U discloses a punching die and a punching device. The punching die includes a lower die assembly and an upper die assembly. During use, the portion of the mother material corresponding to the blanking hole is cut to form a hole, and the material on the outer edge of the mother die is cut off, ultimately forming a product with a certain shape and size and a hole. The upper and lower die assemblies of this device perform relative up and down movement for punching. Due to angle problems, it is not suitable for punching spherical hole plates. The tool is prone to position conflicts with the spherical hexagonal hole plate, which will lead to deviations in the punching position, leaving behind spherical edges, and deformation of the spherical hexagonal hole plate, making subsequent installation of the protective net inconvenient and product quality unstable. At the same time, its production efficiency is low, which is not conducive to ensuring quality and quantity in production. Utility Model Content

[0034] A plurality of punching tools 4 are provided at the power output end of each driving mechanism 3;

[0035] The shape and height of the cutting edge of the punching tool 4 are adapted to the portion to be punched of the spherical hole plate 6 , and when two adjacent punching tools 4 move to the punching position, there is a predetermined gap between the punching tools 4 .

[0036] In actual application, a handle 8 is provided on the base plate 1 to facilitate the movement of the device; the driving mechanism 3 and the punching tool 4 are configured as three arranged at 120° intervals with the positioning clamping mold 2 as the center; the driving mechanism 3 uses a 100*25mm cylinder to achieve precise punching of a spherical protective net 7 with a diameter of 53.8mm from a 0.5mm thick 304# stainless steel hexagonal hole plate, and accurately leave an 11mm non-construction area at an interval of 120 degrees on the spherical surface, and then form an installation edge 71 after cutting.

[0037] Working principle: During operation, a 0.5mm thick 304# stainless steel spherical hole plate 6 is placed on the positioning and clamping die 2 for fixation to ensure that the construction material is accurately positioned. Start the equipment, and the three 100*25mm cylinders work at the same time. The piston rod extends and pushes the punching tool 4 to move forward synchronously. The punching tool 4 contacts and punches the stainless steel plate, and completes the punching according to the preset trajectory, leaving an 11mm non-construction area at an interval of 120 degrees on the spherical surface. After the punching is completed, the cylinder piston rod retracts and removes the punched spherical hole plate 6 from the positioning and clamping die 2, completing a punching process (the spherical hole plate 6 is as shown in the figure). Figure 4 As shown, the hexagonal hole is not shown; Figure 5 (This is a structural diagram of the finished spherical protective net).

[0038] Three pneumatic cylinders spaced 120 degrees apart provide the punching power, ensuring uniform punching force and ensuring punching quality, effectively avoiding material deformation or uneven edges caused by uneven punching force. By positioning the clamping die 2 and the specially designed punching tool 4, conflicts between the punching tool 4 and the spherical hole plate 6 during punching are avoided, ensuring precise punching. The punching position and reserved no-work area can be precisely controlled, improving product accuracy and consistency, and producing stable products. This ensures that a specific width of no-work area is reserved at predetermined angles on the spherical surface, ensuring the proper subsequent installation of the protective net, improving production efficiency, and reducing production costs.
