By using the first cylinder 3 to push the connecting block 4 to move, the connecting block 4 drives the upper die plate 5 to move downward, and the movement of the upper die plate 5 drives the two sliding blocks 6 to slide on the outside of the sliding rod 7, facilitating the stable up and down movement of the upper die plate 5. Then, by using the motor 8 to drive the threaded rod 9 to rotate, the threaded rod 9 drives the threaded block 10 to move through the thread, and the threaded block 10 drives both sides of the sliding plate 12 to slide inside the first chute 11, so as to facilitate the sliding plate 12 to drive the extrusion plate 13 to move toward the lower die 14, facilitating the extrusion plate 13 and the lower die 14 to fix one end of the sealing strip skeleton, and enabling the sealing strip skeleton to maintain a stable position during the processing, reducing the processing error caused by movement or shaking.

[0024] Referring to Figure 1 As shown, a lower die 14 and a fixing plate 15 are fixedly connected to the upper surface of the bottom plate 1.

[0026] Working principle of the utility model: The utility model designs a forming device for the hard skeleton of a sealing strip. The specific structure is as shown in the attached drawings of the specification. Figure 1-6 In this technical solution, through the mutual cooperation among various structures, when forming the hard skeleton of the sealing strip, first place the sealing strip skeleton to be formed on the forming spring steel sheet 16, and align the opening of the sealing strip skeleton with the opening on the forming spring steel sheet 16, so that the sealing strip skeleton can be clamped with the forming spring steel sheet 16. The sensor 17 can be used to detect and ensure that the end of the sealing strip skeleton is placed in place. Then start the motor 8, and use the motor 8 to drive the threaded rod 9 to rotate, so that the threaded rod 9 drives the threaded block 10 to move through the thread. The movement of the threaded block 10 can drive the sliding plate 12 to slide inside the first chute 11, which is convenient for the sliding plate 12 to drive the pressing plate 13 to move towards the lower die 14, so as to facilitate the pressing plate 13 and the lower die 14 to fix one end of the sealing strip skeleton. When the sealing strip skeleton is installed and placed in place, manually press the device start button, and the forming spring steel sheet 16 automatically runs to the preset arc and shape. Then start the first cylinder 3, use the first cylinder 3 to push the connecting block 4, so that the connecting block 4 drives the upper die plate 5 to move downward. The upper die plate 5 drives the two sliding blocks 6 to slide outside the sliding rod 7, which is convenient for the upper die plate 5 and the lower die 14 to close and fix the sealing strip skeleton, ensuring that the opening of the sealing strip skeleton will not deform or become larger. When the device is pressurized to the preset time, turn off the first cylinder 3, so that the upper die plate 5 and the lower die 14 are separated. Then manually take out the pressurized completed sealing strip skeleton, and start the second cylinder 20. Use the second cylinder 20 to push the movable plate 21, so that the movable plate 21 pushes the forming spring steel sheet 16 to move to one side of the fixed plate 15, so that the forming spring steel sheet 16 can be straightened, which is convenient for the next cycle of processing.
