A sliding guide groove 15 is arranged at the concave surface of the lower die holder 11, and the horizontal sliding block 9 is arranged on the sliding guide groove 15.
The working principle is as follows: in the blanking process, the upper die base 1 moves downwards, firstly, the lower die driving block 12 horizontally drives the upper die flanging knife block mounting seat 13 to compress a flanging knife block horizontal return nitrogen spring 14, then the upper die first flanging driving block 6 moves downwards, the horizontal sliding block 9 is pushed to move horizontally, then the vertical upward driven block is pushed to move upwards 10, at the moment, the lower die flanging knife block 8 is synchronously flanged upwards, after the flanging is in direct contact with the upper die first flanging driving block 6, the lower die flanging knife block 8 stops moving upwards and downwards, and the first flanging action is completed.
At the moment, the upper die holder 1 continues to move downwards, the upper die first flanging driving block 6 and the upper die second flanging driving block 5 simultaneously move downwards, when the upper die secondary flanging driving block 5 contacts the lower die flanging knife block 8, the second horizontal flanging is started, after the second horizontal flanging is finished, the upper die starts to move upwards, the flanging knife block returns in the vertical direction by the nitrogen spring 2 and starts to press the upper die flanging knife block 3, the upper die flanging knife block 3 is kept still at the moment, the upper die secondary flanging driving block 5 returns upwards at the moment, the lower die flanging knife block 8 starts to horizontally return, when the upper die first flanging driving block 6 exits from the straight edge movement, the horizontal sliding block 9 starts to retreat, the lower die flanging cutter block 8 also horizontally retreats, and at the moment, the lower die flanging cutter block returns under the action of the return nitrogen spring 4 of the vertically upward driven block until the upper die first flanging driving block 6 leaves the horizontal sliding block 9. At the moment, the upper die flanging knife block mounting seat 13 and the lower die driving block 12 start to be analyzed, the flanging knife block returns to the nitrogen spring 14 in the horizontal direction, and the upper die flanging knife block mounting seat 13 is reset at the same time until the upper die flanging knife block 3 horizontally exits from the flanging surface of the product, and the next flanging is waited after the punching cycle is completed. In the process, the upper and lower die flanging knife blocks are all floating, and meanwhile, two surfaces of the flanging knife blocks participate in flanging, and finally, the flanging is completed twice in one sequence.
The specific flanging steps are as follows:
(1) the upper die holder 1 and the flanging knife block on the upper die holder are separated from the lower die holder 11 together with a vertical return nitrogen spring 2, an upper die flanging knife block 3, a vertical upward return nitrogen spring 4 of a driven block, an upper die second flanging driving block 5 and an upper die first flanging driving block 6, and the state is shown in the attached figure 5;
(2) the upper die base 1 moves downwards, the upper die first flanging driving block 6 moves downwards, the horizontal sliding block 9 is pushed to move in the horizontal direction, then the vertical upward driven block 10 is pushed to move upwards, the lower die flanging knife block 8 is flanged upwards synchronously at the moment, and after flanging is in direct contact with the upper die first flanging driving block 6, the lower die flanging knife block 8 stops moving upwards and downwards to complete the first flanging action, and the state is shown in the attached figure 6;
(3) the upper die base 1 continues to move downwards, and the lower die driving block 12 drives the upper die flanging knife block mounting seat 13 horizontally to compress a flanging knife block return nitrogen spring 14 in the horizontal direction; the upper die first flanging driving block 6 and the upper die second flanging driving block 5 simultaneously descend, when the upper die second flanging driving block 5 contacts the lower die flanging knife block 8, second horizontal flanging is carried out, in the process, the die flanging knife block mounting seat 13 contacts the lower die driving block 12, the upper die flanging knife block 3 firstly descends and then horizontally moves to a working position, and the state is shown in the attached figures 7 and 8; fig. 7 is a schematic view of the upper die flanging knife block 3 going downward, and fig. 8 is a schematic view of the upper die flanging knife block 3 moving horizontally.
