DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to achieve. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that the combination of such technical solutions does not exist and is not within the scope of protection of this application.

[0024] In an embodiment of the present application, a processing technology for a cover plate rounded corner structure is provided, wherein the cover plate rounded corner structure includes a first support rod, a second support rod, a cover plate, and a rounded corner sheet.

[0025] In which, the ends of the first support rod and the second support rod abut against each other and remain basically vertical; the cover plate includes a top surface, and a first folded edge and a second folded edge vertically bent at the edge of the top surface, the top surface is attached to the top walls of the first support rod and the second support rod, and the first folded edge and the second folded edge are respectively attached to the outer side walls of the first support rod and the second support rod; the extension surfaces of the first folded edge and the second folded edge remain basically vertical, and a notch is formed between the first folded edge and the second folded edge, and the fillet piece is installed at the notch, and the fillet piece includes an arc surface and abutting surfaces formed at both ends, a groove is formed between the abutting surface and the arc surface, the abutting surfaces maintain pressure abutment with the first folded edge and the second folded edge respectively, and the groove is placed at the end positions of the first folded edge and the second folded edge, and the arc fillet is formed with the first folded edge and the second folded edge through the arc surface.

[0026] The processing technology for making the rounded corner structure of the cover plate includes the following steps: Step 1: Take two first support rods and two second support rods, cut or punch one side of the end angle of each first support rod to form an arc cut, place the end face of the second support rod against the end side wall of the first support rod and connect them to obtain a rectangular support frame. The arc cut is formed by cutting or punching to ensure that the connection between the support rods is more secure, and the design of the arc cut is conducive to the subsequent installation and positioning of the cover plate.

[0027] Step 2: Take a rectangular plate and punch the four corners of the rectangular plate to obtain a rectangular notch. The rectangular notch obtained by punching reserves space for the subsequent installation of the rounded corner piece and ensures the size accuracy and shape consistency of the cover plate.

[0028] Step 3: bend the four end corners of the rectangular flat plate to form the cover plate. The cover plate is formed by bending to ensure that the shape of the cover plate meets the design requirements and improve the structural strength of the cover plate.

[0029] Step 4: bend at least four long strips to obtain four rounded corner pieces. The rounded corner pieces are formed by bending to ensure that the shape of the rounded corner pieces matches the notch of the cover plate and improve the structural strength of the rounded corner pieces.

[0030] Step 5: Place the rectangular support frame in the cover plate, and make the outer side walls of the first support rod and the second support rod close to the inner walls of the first folded edge and the second folded edge. By placing the rectangular support frame in the cover plate, the support rod and the cover plate are closely combined, and the stability of the overall structure is improved.

[0031] Step 6: Fix the rectangular support frame and the cover plate. By fixing the rectangular support frame and the cover plate, the connection between the two is ensured to be firm and reliable, thereby improving the rigidity and durability of the overall structure.

[0032] Step 7: bend the abutting surfaces at both ends of the fillet sheet inward and place them on the notches of the cover plate. After releasing, the abutting surfaces of the fillet sheet rebound and maintain pressure abutment with the first folded edge and the second folded edge. The abutting surfaces of the fillet sheet maintain pressure abutment with the notches of the cover plate to ensure that the fillet sheet is firmly installed and improve the sealing between the fillet sheet and the cover plate.

[0033] The following are specific details regarding some improved embodiments.

[0034] In some embodiments, the outer wall extension lines of the first folded edge and the second folded edge are tangent to the arc surface of the fillet sheet. By designing that the outer wall extension lines are tangent to the arc surface of the fillet sheet, a smooth transition between the fillet sheet and the folded edge is ensured, stress concentration is avoided, and the durability of the structure is improved.

[0035] In some embodiments, the first support rod and the second support rod are fastened by screwing, riveting, or welding. Through the selection of multiple connection methods, the most suitable connection method can be selected according to the specific application environment to ensure the connection strength between the support rods.

[0036] Connection method of cover plate and rectangular support frame: In some embodiments, the cover plate and the rectangular support frame are fastened by riveting, welding, or bonding. Through different connection methods, the most suitable connection method can be selected according to actual needs to improve the bonding strength between the cover plate and the support frame.

[0037] In some embodiments, the steps 1, 2, and 4 can be performed simultaneously or in a different order. By flexibly adjusting the order of the processing steps, the production process can be optimized and the production efficiency can be improved.

[0038] Flexibility in Steps 5 and 7: In some embodiments, step 5 and step 7 can be performed simultaneously or in a reverse order. By flexibly adjusting the order of step 5 and step 7, the process can be adjusted according to actual operation convenience to improve assembly efficiency.

[0039] In some embodiments, a plurality of third support rods are connected between two second support rods arranged at intervals. By providing the third support rods, the stability of the overall structure is increased, and the bearing capacity of the support system is improved.

[0040] In some embodiments, the end of the third support rod abuts against the inner side of the second support rod and is fastened by screws. The third support rod is fastened by screws to ensure that it is firmly and reliably installed and easy to disassemble and maintain.

[0041] In some embodiments, the cover plate further includes a lower baffle plate integral with the first folded edge and the second folded edge, the lower baffle plate is parallel to the top surface, and the lower baffle plate is used to limit the displacement of the fillet sheet. By providing the lower baffle plate, the fillet sheet is prevented from being displaced during use, thereby ensuring the stability and reliability of the fillet sheet.
