[0025] As Figure 4As shown, in an embodiment of the present invention, the lifting assembly includes two groups of vertical telescopic cylinders 309, which are fixedly installed on the top plate of the stamping frame 301, and their telescopic ends are fixedly connected to the upper end of the lower pressing platform 303. The present invention uses two groups of vertical telescopic cylinders 309 to telescopically drive the lower pressing platform 303 to move in the vertical direction.

[0026] like Figure 3 and Figure 4 As shown, in the embodiment of the present invention, the clamping plate group 302 includes a clamping block 3021 and a clamping plate 3022, and the clamping plate 3022 is fixedly connected to the corresponding clamping plate 3022 through a connecting column. The clamping block 3021 is slidably installed in the limiting slide grooves opened on both sides of the lower pressing platform 303 and abuts against the corresponding side surfaces of the stamping punch 305. The spacing between the two groups of clamping blocks 3021 is equal to the width of the spring sheet blank, and the two groups of clamping plates 3022 are driven by the driving component 306 to move in a mirror image. In the present invention, when the stamping punch 305 is fixedly installed on the lower pressing platform 303, the driving component 306 drives the two groups of clamping plate groups 302 to approach each other in a mirror image, and the two groups of clamping blocks 3021 slide along the limiting slide groove and abut against the two sides of the stamping punch 305. The spacing between the two groups of clamping plate groups 302 can be automatically adapted to the different width specifications of the spring sheet blank in the stamping punch 305.

[0027] Furthermore, the driving assembly 306 further includes two groups of dual-axis motors 3063, two groups of mounting sliders 3061 and two pairs of driving screw rods 3062.

[0029] At the same time, when the transmission amplification assembly 307 is driven to displace along the vertical direction by the lower pressing table 303, the transmission column 3071 at the end of the clamping plate 3022 can slide along the vertical communication groove on the transmission angle plate 3072.

[0030] As Figure 5As shown, in the embodiment of the present application, the third guide column 409 is fixedly installed at the bottom of the lifting plate 403, the third guide column 409 is slidingly installed on the corresponding driving support plate 402 in the vertical direction, and the sliding guide groove 410 includes a connected horizontal straight groove and an inclined groove, when the sliding column 411 is slidingly installed on the horizontal straight groove, the two groups of pressing plates 404 are mirror-symmetrically pressed on the two ends of the metal plate 5, and when the sliding column 411 is slidingly installed on the inclined groove, the two groups of pressing plates 404 are separated from the upper and lower sides of the metal plate 5, when the feeding assembly 4 realizes the feeding operation of the metal plate 5, the telescopic assembly installed on one side of the machine tool 1 is elongated to drive the driving main plate 401 to move towards the direction close to the punching frame 301, and the elastic support of the second elastic assembly drives the driving support plate 402 to move in the same direction as the driving main plate 401, the driving support plate 402 drives the lifting plate 403 slidingly installed on the upper side to move towards the direction close to the punching frame 301 in the process of moving, and the lifting plate 403 moves horizontally under the action of force, and the sliding column 411 on the side of the lifting plate 403 slides along the inclined groove of the sliding guide groove 410 to the horizontal straight groove; Specifically, when the two pairs of sliding columns 411 slide along the inclined groove, the lifting plate 403 connected with the sliding column 411 moves towards the metal plate 5 under the action of the lifting plate 403, the two groups of pressing plates 404 are pressed on the two sides of the metal plate 5 under the action of the first elastic assembly, and when the two pairs of sliding columns 411 slide from the inclined groove to the horizontal straight groove, the two groups of pressing plates 404 are pressed on the two sides of the metal plate 5 to fix the metal plate 5, and the driving main plate 401 drives the pressing plate 404 to move to realize the feeding of the metal plate 5, when one end of the two groups of pressing plates 404 abuts against the positioning stopper 308, the positioning stopper 308 positions the movement of the two groups of pressing plates 404, when the telescopic assembly is further elongated, the second elastic assembly is deformed to realize the feeding of the metal plate 5 to the preset stroke by the feeding assembly 4; Further, when the punching punch 305 is driven by the lower pressing table 303 to punch and cut the metal plate 5, the telescopic assembly is retracted to drive the driving main plate 401 to move away from the punching structure, and because the metal plate 5 is in a punching fixed state, the pressing plates 404 on the two sides of the metal plate 5 cannot drive the metal plate 5 to reset and retract when the pressing punch 305 is separated from the upper end surface of the metal plate 5, and the telescopic assembly has completed the reset and retreat operation of the two groups of pressing plates 404.

The two ends of the multiple groups of second springs 408 are respectively fixedly connected to the driving support plate 402 and the end of the second guide column 407. When the telescopic component is extended and the transmission drives the two groups of clamping plates 404 to move to abut against the positioning block 308, the telescopic component is further extended at this time, driving the two groups of second guide columns 407 to move further, causing the second spring 408 to deform.

[0032] like Figure 5 As shown, in an embodiment of the present invention, the telescopic assembly includes two groups of horizontal telescopic cylinders 6, which are fixedly installed on the machine tool 1, and their telescopic ends are fixedly connected to the driving surface of the driving main board 401.
