Description

Technical Field

[0001] This utility model relates to the field of steel structure processing technology, specifically a rust-proof steel structure sheet cutting structure. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates. These components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. Steel structures are prone to corrosion. Generally, steel structures require rust removal, galvanizing, or painting, and regular maintenance. Currently, based on market needs and the wide range of applications for steel structures, a new type of rust-proof steel structure is proposed to improve the durability and corrosion resistance of steel structures. This typically involves covering the steel structure surface with sheet metal for protection and decoration. Sheet metal is also needed to protect and prevent rust at welded joints. Precise and efficient cutting of the sheet metal is crucial. However, the amount of sheet metal used for wrapping small I-beams, channel steel, and joints is currently small, making frequent use of large cutting equipment uneconomical and leading to high maintenance costs. Furthermore, cutting with an angle grinder can easily result in excessive burrs at the edges, affecting the aesthetics of the wrapping. Additionally, cutting thin sheet metal with a shearing blade can cause uneven stress and deformation at the cut. Therefore, a new type of rust-proof steel structure sheet metal cutting structure is proposed. Summary of the Invention

[0018] See Figure 1-4 This embodiment is a sheet metal cutting structure for rust-proof steel structures. A base 1 supports and mounts the sheet metal cutting structure. A cylindrical first support rod 2 is welded to the top of the base 1. A horizontally placed sleeve 3 is welded to the top of the first support rod 2. A rotating rod 4 passes through the sleeve 3 and can rotate within the sleeve 3. A cutting disc 5 is welded to one end of the rotating rod 4, and a rocker arm 6 is detachably installed at the other end. The cutting disc 5 has a circular structure, and its circumference is inclined towards the rotating rod 4 to form a beveled structure, making the cutting disc 5 sharper. A spring 7 is fitted onto the surface of the rotating rod 4 near the cutting disc 5. The shim 8 and spring 7 are located on one side of the cutting disc 5. The shim 8 is located between the spring 7 and the sleeve 3, and the outer diameter of the shim 8 is larger than the outer diameter of the sleeve 3, which makes the spring 7 more stable. A cylindrical second support rod 9 is welded to the top of the base 1, and the second support rod 9 is located on one side of the first support rod 2. A fixing rod 10 is installed on the top of the second support rod 9. A bearing 11 is fitted at one end of the fixing rod 10. The bearing 11 and the cutting disc 5 are arranged vertically and tangent to each other. The spring 7 can continuously push the cutting disc 5 to one side, so that the cutting disc 5 and the outer surface of the bearing 11 are more closely fitted, which improves the shearing effect.

[0019] Furthermore, a connecting shaft 12 is welded to the end of the rotating rod 4 away from the cutting disc 5. A limiting block 13 is provided at the top of the surface of the connecting shaft 12. An external thread 14 is provided on the surface of the connecting shaft 12 away from the rotating rod 4, and the external thread 14 is located on one side of the limiting block 13. A through hole 15 is provided at one end of the rocker arm 6. A slot 16 is provided on the inner side wall of the through hole 15. The slot 16 matches the limiting block 13. When the connecting shaft 12 passes through the through hole 15, the slot 16 and the limiting block 13 are engaged, so that the rocker arm 6 drives the rotating rod 4 to rotate. A nut 17 is threadedly connected to the external thread 14 on the surface of the connecting shaft 12. The nut 17 is used to fix the rocker arm 6.

[0020] Furthermore, a workbench 18 is welded to the top of the fixing rod 10, and an inclined plate 19 is welded to each side of the bottom of the workbench 18. The other end of the inclined plate 19 is welded to the base 1. The height of the top surface of the workbench 18 is on the same plane as the cutting disc 5 and the tangent point of the bearing 11, which makes it easier to use by simply moving the sheet metal on the workbench 18 to complete the cutting work.

[0021] Furthermore, a cross plate 20 is connected between the first support rod 2 and the second support rod 9, which further improves the stability during operation.

[0022] The working principle of this embodiment is as follows: When installing the cutting disc 5, firstly, the rotating rod 4 is fitted with the spring 7 and the washer 8 in sequence. Then, the end of the rotating rod 4 fitted with the spring 7 and the washer 8 is inserted into the sleeve 3. Then, the rotating rod 4 is continuously pushed to one side. At this time, the washer 8 and the sleeve 3 are limited. At the same time, the cutting disc 5 squeezes the spring 7 to one side. When the cutting surface of the cutting disc 5 contacts the bearing 11, the cutting is complete. Finally, the through hole 15 and the slot 16 of the rocker arm 6 are aligned with the connecting shaft 12 for installation. Finally, the nut 17 is connected to the external thread 14 to complete the installation. When the cutting disc 5 is replaced for maintenance later, the operation is reversed. During operation, the sheet metal is first placed on the workbench 18 and then moved to enter between the cutting point of the cutting disc 5 and the bearing 11. At the same time, the rocker arm 6 is rotated to make the rotating rod 4 drive the cutting disc 5 to rotate. The cutting disc 5 is in close contact with the bearing 11, thereby driving the bearing 11 to rotate. When the cutting disc 5 and the bearing 11 rotate relative to each other, the sheet metal is cut through the cutting point to complete the cutting work.
