DETAILED DESCRIPTION OF THE INVENTION

[0019] The technical solutions in the utility model will be further described below with reference to the drawings and embodiments.

[0020] As Figures 1 - 3 shown, an embodiment of the utility model provides a stamping and welding integrated die for a fuel tank strap, including:

[0021] A U-shaped frame 1, a support plate 8 is fixed on the U-shaped frame 1, a rubber ring 10 is fixed on the support plate 8, and the rubber ring 10 is located outside the negative electrode post 11. In this way, after the fuel tank strap is placed on the support plate 8, it does not contact the negative electrode post 11.

[0022] Stamping and welding assembly; the stamping and welding assembly includes two limiting columns 6 fixed on the U-shaped frame 1 and located on both sides of the support plate 8. A bending rod 7 for bending the fuel tank strap by rotation is provided below the limiting column 6. Among them, a reversing box 12 is installed at the rear side of the U-shaped frame 1, a motor 13 is installed on the reversing box 12, a connecting block 9 is installed on the reversing box 12, and the bending rod 7 is fixed on the connecting block 9. Two meshing bevel gears are provided in the reversing box 12, and short shafts are fixed on both bevel gears. One of the short shafts is fixedly connected to the output end of the motor 13, and the other short shaft is fixedly connected to the connecting block 9. Among them, the upper end of the bending rod 7 is flush with the upper end of the support plate 8, which can also support the fuel tank strap. Marks can be made in the middle of the fuel tank strap and on the support plate 8. When placing the fuel tank strap, align the marks so that the bending lengths are equal, that is, center the fuel tank strap. It is also possible to center the fuel tank strap by means other than those disclosed above.

[0023] Place the fuel tank strap on the support plate 8 with both ends located between the bending rod 7 and the limiting column 6. When the motor 13 works, it drives the short shaft to rotate. Through the transmission and direction change of the bevel gears, the connecting block 9 and the bending rod 7 can be rotated. The short shaft and the bending rod 7 are respectively arranged at both ends of the connecting block 9 to bend the fuel tank strap at 90°.

[0024] Two pushing mechanisms are installed on the U-shaped frame 1. The pushing mechanism includes a mounting plate 3 fixed on the U-shaped frame 1, an electric push rod 4 is installed on the mounting plate 3, and a wedge plate 5 is fixed at the output end of the electric push rod 4. After the fuel tank strap is bent at 90°, the electric push rod 4 drives the wedge plate 5 to move. The wedge plate 5 abuts against the fuel tank strap. As the wedge plate 5 moves, the fuel tank strap can be pushed. Since the limiting column 6 is fixed, the wedge plate 5 drives the fuel tank strap to move around the outer wall of the limiting column 6, and finally the fuel tank strap is horizontally arranged.

[0025] Push the bent fuel tank strap to the horizontal position. There are two hydraulic cylinders 2 installed at the upper end of the U-shaped frame 1. The output end of the hydraulic cylinder 2 is fixed with a sleeve 14. A stamping cylinder 15 is slidably connected inside the sleeve 14. A spring 16 is fixed between the stamping cylinder 15 and the sleeve 14. A positive electrode column 17 that can pass through the stamping cylinder 15 is fixedly installed inside the sleeve 14 in an insulated manner. A negative electrode column 11 opposite to the positive electrode column 17 is provided on the support plate 8. Then, the hydraulic cylinder 2 drives the sleeve 14 to move downward. The sleeve 14 drives the stamping cylinder 15 to move downward. The stamping cylinder 15 abuts against the bent fuel tank strap. As the stamping cylinder 15 moves downward, it drives the fuel tank strap to move downward. Finally, the bent fuel tank strap abuts against the fuel tank strap. The output end of the hydraulic cylinder 2 continues to move downward. Relative movement occurs between the stamping cylinder 15 and the sleeve 14. At this time, the spring 16 is compressed. Due to the reaction force of the spring 16, the pressure of the stamping cylinder 15 on the fuel tank strap increases. At this time, the rubber ring 10 deforms, and the fuel tank strap abuts against the negative electrode column 11. As the stamping cylinder 15 slides inside the sleeve 14, the positive electrode column 17 abuts against the fuel tank strap. Through the cooperation of the negative electrode column 11 and the positive electrode column 17, spot welding of the fuel tank strap is achieved.

[0026] After welding is completed, both ends of the fuel tank strap are sleeved on the limit posts 6, and then the fuel tank strap can be pulled out, which is convenient for blanking. In this way, the fuel tank strap is also bent into a through-hole shape for subsequent installation of bolts and the like.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
