[0002] Sheet metal parts are products manufactured using sheet metal processing techniques, including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming. Their most significant characteristic is that the thickness of the same part is consistent. Sheet metal parts are products manufactured using sheet metal processing techniques. Due to their characteristics such as light weight, high strength, electrical conductivity, low cost, and good mass production performance, they have been widely used in fields such as electronics, communications, automotive, and medical devices.
[0003] Bending sheet metal parts are a type of sheet metal parts. The process involves placing the workpiece to be formed on a bending machine, lifting the brake shoes with a lifting lever, sliding the workpiece to the appropriate position, lowering the brake shoes onto the workpiece to be formed, and then applying force to the bending lever on the bending machine to form the part.
[0004] Bending sheet metal parts are typically assembled from multiple sheet metal parts during use. Traditionally, when assembling bending sheet metal parts, the connection between two sheet metal parts needs to be welded with a welding gun to ensure the connection strength between the two sheet metal parts. However, when sheet metal parts need to be replaced, it is difficult to separate the two sheet metal parts, and they need to be re-welded. The original weld points need to be ground and cleaned before they can be welded again, which will also cause some damage to the sheet metal parts and affect their strength. Therefore, a new solution is needed to improve the flexibility of sheet metal parts installation. Utility Model Content

Detailed Implementation
[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0021] A high-strength sheet metal part, such as Figure 1 , Figure 2 and Figure 3 As shown, the part includes a sheet metal body, which comprises a top plate 1 and two connecting plates 2. The two connecting plates 2 are fixedly connected to both sides of the top plate 1. A sliding groove 201 is provided on one side wall of each connecting plate 2. One sliding groove 201 is located on the outer side of the sheet metal body, and the other sliding groove 201 is located on the inner side of the sheet metal body. A fixing insert 5 is slidably connected within the sliding groove 201. Fixing holes 6 are provided on the fixing insert 5, the connecting plate 2, and the limiting insert 4. During connection, the fixing insert 5 is slidably connected in the sliding groove 201 on the two connecting plates 2, and the fixing insert 5 abuts against the two connecting plates 2. The two connecting plates 2 are connected by the fixing insert 5 and the sliding groove 201, and the position of the fixing insert 5 is restricted by the two limiting inserts 4. The connecting plates 2, the fixing insert 5 and the limiting insert 4 are fixed by bolts passing through the fixing holes 6 and threaded with nuts. This improves the flexibility when installing or disassembling multiple sheet metal parts, while also having good connection strength and reducing the possibility of adjacent sheet metal parts falling off.
[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the sheet metal body includes a top plate 1, two connecting plates 2, and two fixing plates 3. The two connecting plates 2 are located between the top plate 1 and the fixing plates 3. The connecting plates are perpendicular to the top plate 1 and the fixing plates 3, and the fixing plates 3 are parallel to the top plate 1. A sliding groove 201 is provided on one side wall of the connecting plate 2, as shown in the figure. Figure 4As shown, the depth of the sliding groove 201 is greater than half the thickness of the connecting plate 2. When the two sheet metal parts are connected, the connecting plates 2 of the two sheet metal parts abut against each other, and the sliding grooves 201 on the two connecting plates 2 face opposite directions. Due to the depth of the sliding groove 201, an opening 7 is formed at the connection point of the two connecting plates 2 for the fixing insert 5 to pass through. The fixing insert 5 can abut against the bottom of the sliding groove 201 on the connecting plate 2 of the two sheet metal parts through the opening 7. The limiting insert 4 is located above the fixing insert 5 and acts as a restraining element for the fixing insert 5. The limiting insert 4, which serves a fixing function, includes a sliding plate 402 and a reinforcing plate 401. The cross-section of the limiting insert 4 is Z-shaped. The sliding plate 402 is slidably connected in the sliding groove 201, and the reinforcing plate 401 is located outside the sliding groove 201. When two sheet metal parts are connected, the sliding plate 402 serves to limit the fixing insert 5, thereby improving the connection strength between adjacent sheet metal parts. Furthermore, the reinforcing plate 401 located outside the sliding groove 201 abuts against the outer wall of the connecting plate 2 of the adjacent sheet metal parts, further improving the connection strength between adjacent sheet metal parts.
[0023] like Figures 1-5 As shown, limiting grooves 202 are provided on both inner sidewalls of the sliding groove 201. Sliding protrusions 403 are fixedly connected to both sidewalls of the sliding plate 402. An insertion groove 203 is provided on the end face of the connecting plate 2 with the sliding groove 201. The insertion groove 203 communicates with the limiting groove 202. The cross-sectional shape of the insertion groove 203 is consistent with the cross-sectional shape of the sliding protrusion 403. The sliding plate 402 and the sliding protrusion 403 can extend out of the sliding groove 201 through the insertion groove 203, and the sliding protrusion 403 is slidably connected to the limiting groove 202. Within 02, this structure improves the flexibility of installing and removing the limiting insert 4. A fixing member 404 is provided at the end of the sliding plate 402 away from the reinforcing plate 401. The fixing member 404 abuts against the end of the fixing insert 5. The thickness of the fixing member 404 is equal to the thickness of the fixing insert 5. When the position of the fixing insert 5 is restricted by the two limiting inserts 4, the fixing member 404 can push the fixing insert 5 and prevent the fixing insert 5 from sliding, thereby improving the connection strength of adjacent sheet metal parts and the stability and convenience of installation.
[0024] like Figure 1-5As shown, a number of pins 101 are fixedly connected to one end of the top plate 1, and a fixing groove 102 is opened at the other end for the pins 101 to be inserted. When connecting two sheet metal parts, the pins 101 are inserted into the fixing groove 102, which further improves the stability and strength of the connection between adjacent sheet metal parts. A number of mounting slots 301 are opened on the fixing plate 3. The sheet metal parts can be fixed to the object to be installed by bolts and nuts and mounting slots 301. Preferably, fixing holes 6 are opened on the limiting insert 4, the fixing insert 5 and the connecting plate 2. The fixing holes 6 of the limiting insert 4 are located on the reinforcing plate 401, and the fixing holes 6 of the connecting plate 2 are located in the sliding groove 201. The hole diameters of the fixing holes 6 on the limiting insert 4, the fixing insert 5 and the connecting plate 2 are the same to ensure the stability and connection strength when the bolts and nuts fix adjacent sheet metal parts.
[0025] Working principle: When connecting multiple sheet metal parts, the pin 101 on one sheet metal part is inserted into the fixing groove 102 of another sheet metal part, and the connecting plates 2 of the two sheet metal parts abut against each other. The width of the fixing insert 5 is the same as the width of the sliding groove 201. The fixing insert 5 is placed into the sliding groove 201, and the fixing insert 5 is slid so that the fixing insert 5 slides on the sliding groove 201 on the two connecting plates 2. The fixing hole 6 on the fixing insert 5 and the fixing hole 6 on the connecting plate 2 are coaxially arranged. One end of the sliding plate 402 of the two limiting inserts 4 is inserted into the sliding groove 203 through the insertion groove 203. Within 01, the sliding plate 402 is slidably connected to the sliding groove 201 via the limiting groove 202. The fixing piece 404 on the sliding plate 402 pushes and restricts the position of the fixing piece 5 within the sliding groove 201, so that the limiting piece 4, the fixing piece 5 and the fixing hole 6 on the connecting plate 2 are coaxially arranged. The bolt passes through the fixing hole 6, through the limiting piece 4, the fixing piece 5 and the connecting plate 2, and is connected by the nut thread, thus completing the installation and fixing of the adjacent sheet metal parts. When disassembly is required, simply remove the bolt and nut, slide the limiting piece 4 and the fixing piece 5 and remove them to complete the disassembly of the adjacent sheet metal parts.
