[0002] Sheet metal is a product made by a comprehensive cold processing process on metal sheets. This process includes shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming and other steps. Common sheet metal materials include galvanized sheet, cold-rolled sheet, aluminum sheet and stainless steel sheet. Sheet metal made of metal sheets has been widely used in construction, electronic appliances, communications, automotive industry, medical equipment and other fields due to its light weight, high strength, corrosion resistance and conductivity.

[0003] During the forming process of sheet metal parts, the metal sheets are bent. However, the metal sheets have a certain ductility, which makes it easy for the sheet metal parts to be stretched and deformed at the bends when subjected to external forces generated by extrusion. This makes the sheet metal parts easy to deform when used under long-term external forces, thereby affecting the strength and stability of the overall structure.

[0017] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0018] Example: A tensile sheet metal part, such as Figure 1 and Figure 2As shown, it includes a sheet metal body 1, which includes an arc-shaped bending portion 2 and a rectangular straight plate portion 3 integrally formed on both sides thereof. The bending portion 2 and the straight plate portion 3 are both formed by bending a stainless steel plate. The stainless steel material has strong tensile resistance, and its tensile strength is between 800 MPa and 1300 MPa, so that the manufactured sheet metal body 1 is not easily stretched and deformed by external forces. The straight plate portion 3 is provided with a rectangular through groove 4 along its length direction, and a rectangular connecting plate 5 is clamped in the through groove 4. This connecting plate 5 is made of stainless steel, and the length and width of the connecting plate 5 are respectively the same as the length and width of the through groove 4, so that the connecting plate 5 can be tightly clamped in the through groove 4.

[0019] like Figure 1 and Figure 2 As shown, the thickness of the connecting plate 5 is greater than the thickness of the straight plate portion 3, so that the length sides of the connecting plate 5 pass through the length sides of the through groove 4 respectively, and a rectangular groove 6 is opened on both sides of the length of the connecting plate 5. The length of the groove 6 is the same as the length of the connecting plate 5. The distance between the grooves 6 on both sides of the connecting plate 5 is greater than the thickness of the straight plate portion 3. The connecting plate 5 and the groove 6 are welded and fixed when they are in contact. After the connecting plate 5 is clamped in the groove 6, the thickness of the straight plate portion 3 at the groove 6 is guaranteed, thereby avoiding the sheet metal body 1 from bending at the through groove 4 when subjected to external force.

[0020] like Figure 1 As shown, a plurality of rectangular tensile rods 7 are clamped between the two grooves 6 on the side where the two connecting plates 5 are close to each other, and a plurality of tensile rods 2 8 with arc-shaped cross sections are clamped between the two grooves 6 on the side where the two connecting plates 5 are far away from each other. The cross-sectional shapes of the two ends of the tensile rod 1 7 and the cross-sectional shapes of the two ends of the tensile rod 2 8 are the same as the cross-sectional shapes of the groove 1 6. The tensile rod 1 7 and the tensile rod 2 8 are made of stainless steel. The joints between the tensile rod 1 7 and the tensile rod 2 8 and the groove 1 6 are reinforced by welding, so that the plurality of tensile rods 1 7 is fixed on the concave side of the connecting plate 5 at the bending portion 2, so that a number of anti-tension rods 2 are fixed on the convex side of the connecting plate 5 at the bending portion 2. Through a number of anti-tension rods 1 7 and a number of anti-tension rods 2 8, tension can be generated on both sides of the sheet metal body 1, so that the bending portion 2 and the straight plate portion 3 between the anti-tension rods 1 7 and the anti-tension rods 2 8 have strong tensile resistance, and the curvature of the anti-tension rods 2 8 is the same as that of the bending portion 2, which avoids contact friction between the anti-tension rods 1 7 and the anti-tension rods 2 8 and the sheet metal body 1 and damage to the sheet metal body 1.

[0021] like Figure 1 and Figure 2As shown, the straight plate portion 3 is located between the bending portion 2 and the through groove 1 4 and is provided with a rectangular through groove 2 10. The length of the through groove 2 10 is the same as that of the through groove 1 4. The through groove 2 10 between the bending portion 2 and the through groove 1 4 is not easily bent by force. The end surfaces of the tension rod 1 7 and the tension rod 2 8 close to each other are provided with two grooves 2 11. The two grooves 2 11 on the tension rod 1 7 and the two grooves 2 11 on the tension rod 2 8 are respectively arranged horizontally with the two through grooves 2 10 in the vertical direction. The tension rod 1 7 and the tension rod 2 8 are arranged horizontally with the two through grooves 2 There are two rectangular anti-tension rods 3 9 clamped in between. The anti-tension rods 3 9 are made of stainless steel. The thickness of the anti-tension rods 3 9 is the same as the width of the through groove 2 10. The cross-sectional shape of the anti-tension rod 3 9 near the end of the anti-tension rod 1 7 is the same as the cross-sectional shape of the groove 2 11 on the anti-tension rod 1 7. The cross-sectional shape of the anti-tension rod 3 9 near the end of the anti-tension rod 2 8 is the same as the cross-sectional shape of the groove 2 11 on the anti-tension rod 2 8, so that the anti-tension rod 3 9 can pass through the through groove 2 10 and be tightly clamped with the anti-tension rod 1 7 and the anti-tension rod 2 8 and be arranged perpendicular to the straight plate part 3.

[0022] like Figure 1 and Figure 2 As shown, the joints between the tension rod three 9 and the through groove two 10 and the joints between the tension rod three 9 and the groove two 11 are welded and reinforced, and the tension rod three 9 is used to reinforce the tension rod one 7, the tension rod two 8 and the straight plate portion 3, thereby improving the tensile resistance and stability of the tension rod one 7 and the tension rod two 8, thereby strengthening the tensile deformation effect exerted by the tension rod one 7 and the tension rod two 8 on the sheet metal body 1. A certain number of tension rods one 7, tension rod two 8 and tension rod three can be set according to the use scenario of the sheet metal body 1 and the required tensile resistance. By adding tension rods The number of tension rods 1 7, anti-tension rods 2 8 and stretching rods 3 can further improve the anti-tensile effect on the bending portion 2. Several cavities 12 with rectangular cross-sections are formed between several adjacent anti-tension rods 3 9 and through grooves 2 10. The forces acting on the sheet metal body 1 can be dispersed through several anti-tension rods 1 7, anti-tension rods 2 8 and anti-tension rods 3 9. At the same time, the stresses formed on the sheet metal body 1 by external forces can be released through several cavities 12, thereby improving the bearing capacity of the sheet metal body 1, reducing the fatigue of the sheet metal body 1 in long-term use, and improving the service life.

[0023] Working principle: After opening the through groove 1 4 and the through groove 2 10 on the straight plate portion 3 on both sides of the bending portion 2, the connecting plate 5 is clamped into the through groove 1 4. According to the use scenario of the sheet metal body 1 and the required tensile strength, the two ends of the several tensile rods 1 7 are respectively clamped into the groove 1 6 on the side close to each other of the two connecting plates 5. After the several tensile rods 3 9 pass through the through groove 2 10, they are clamped with the groove 2 11 on the tensile rod 1. The two ends of the several tensile rods 2 8 are respectively clamped into the grooves on the side away from each other of the two connecting plates 5. 16, and at the same time, the groove 2 11 on the anti-tension rod 2 8 is engaged with the anti-tension rod 3 9, and the engaging parts of the connecting plate 5 and the through-slot 1 4, the engaging parts of the anti-tension rod 1 7 and the anti-tension rod 2 8 and the connecting plate 5, the engaging parts of the anti-tension rod 3 9 and the anti-tension rod 1 7 and the anti-tension rod 2 8, and the engaging parts of the anti-tension rod 3 9 and the through-slot 2 10 are reinforced by welding, and tensile force is applied to both sides of the bending part of the sheet metal body 1 by a plurality of tensile rods 1, a plurality of tensile rods 2 and a plurality of tensile rods 3, thereby improving the tensile resistance of the sheet metal body 1.
