after the secondary stamping and the primary stamping are finished, the continuous stamping state is kept, the second stamping block 9 and the second die 73 are matched to keep the extrusion pressing state of the secondary stamping end of the sheet metal part, meanwhile, the first stamping block 46 and the first die 41 are matched to keep the extrusion pressing state of the primary stamping end of the sheet metal part, then the stepping motor on the driving mechanism 21 on the bearing bottom column 2 corresponding to the second bearing base 7 is started to rotate, and/or the stepping motor on the driving mechanism 21 on the bearing bottom column 2 corresponding to the first bearing base 3 is started to rotate, so that the stepping motor drives the driving gear to be meshed with the bearing tooth grooves 14 to move, and finally the bearing bottom 2 drives the second bearing base 7, the second stamping block 9 and the second die 73 above the second bearing base 7 to move, the first bearing base 3 and the first stamping block 46, the second stamping block 73 and the like above the first bearing base 3 to move, The first die 41 and other related components move to increase the distance between the second bearing base 7 and the first bearing base 3, and in the process that the second bearing base 7 and the first bearing base 3 are away from each other, because the second stamping block 9 and the second die 73 are matched to keep the extrusion pressing state of the secondary stamping end of the sheet metal part, and meanwhile, the first stamping block 46 and the first die 41 are matched to keep the extrusion pressing state of the primary stamping end of the sheet metal part, the sheet metal part with the length of the initial stretching distance between the second bearing base 7 and the first bearing base 3 begins to be stretched, and the sheet metal part is gradually stretched until the preset deformation is reached, and then is kept for a certain time to prevent the sheet metal part which is stretched from elastic deformation; after the drawing of the sheet metal part between the second bearing base 7 and the first bearing base 3 is finished, the pushing worm set 32, the extrusion cam and the pushing frame 47 are controlled to move forward, because the height of the pushing frame 47 is higher than that of the first die 41, the pushing frame 47 passes over the first die 41 at this time, so that the pushing block 49 below the pushing frame 47 slides into the stamping slot 42, on one hand, the sheet metal part stamped for the first time in the second stamping slot 42 is pushed to be separated from the stamping slot 42, on the other hand, the sheet metal part stamped for the second time is pushed to be separated from the second die 73, the pushing worm set 32, the extrusion cam and the pushing frame 47 are controlled to move forward continuously, the pushing block 49 below the pushing frame 47 continuously pushes the sheet metal part for the first time to move forward, finally, the sheet metal part for the first time is moved to be above the second die 73, and then the second stamping block 9 is controlled to move downward, and is matched with a second die 73 to carry out secondary stamping on the part which finishes the primary stamping at the other end of the sheet metal part; finally, after the secondary stamping of the other end of the sheet metal part is completed, the servo motor is controlled to work, the second die 73 is driven to move through the adjusting shaft column 72, in the moving process of the second die 73, the sheet metal part is extruded by separating the pushing part 75, the finally-formed sheet metal part is separated from the second die 73, the separated sheet metal part subjected to machining forming drops on the unloading mechanism 8, then the servo motor on the unloading mechanism 8 is started and drives the gear rack to rotate, further the transportation pushing part 82 is driven to slide in a reciprocating manner, further the transportation pushing part 82 pushes the extruded sheet metal part, the sheet metal part moves to the inner side of the transportation sliding frame 83, and further the sheet metal part subjected to secondary stamping and stretching slides in a directional manner and is collected in a collection box in a concentrated manner.

In conclusion, through further optimization of all parts of the device, on one hand, secondary stamping is performed again after the sheet metal part is stamped once, so that the stamping precision and quality are improved; on the other hand, the effect that the sheet metal part which is punched once is separated from the punching slot 49 when the pushing block 49 slides in the punching slot 42 is improved, and the pushing block 49 can be further ensured to slide out of the punching slot 42, so that the sheet metal part which is punched once is pushed to the lower part of the second die 73 to be punched for the second time; thirdly, the base 3 is born to the first base 3 that bears and the base 7 is born to the second through setting up can relative motion to make first base 3 and the second of bearing bear the base 7 and can mutually support and draw the shape work to the sheet metal component, saved the work piece and drawn the production processes that the shape was again carried out after the punching press panel beating, improved production efficiency, save special drawing the shape device, reduced manufacturing cost, have comparatively apparent technological effect and advantage.
