The part of the lower die includes lower die holder, and the punch-pin towards part of the upper die is provided on the lower die holder, the punch-pin and drawing Left and right stringer lower plate product after being stretched into shape is adapted, and at least two positioning pins are fixed on the punch-pin.
Further, at least two first correcting sliding blocks are fixed on the side wall of the side of the material pressing core.
Further, it is additionally provided with limited block in the front side wall of the material pressing core and rear wall, the limited block is to limit pressure Expect the opposite sliding distance of core and upper die holder.
Further, accommodating notch is offered respectively in the left and right sides of the lower die holder, in the side wall of the accommodating notch On be provided with the second correcting sliding block and guide part that upper die holder matches.
Further, it is also installed with pulp-collecting box on the lower die holder, the pulp-collecting box and the discharge road phase on the punch-pin Connection.
Further, the front and rear sides of the upper die holder and lower die holder extend to form at least two groups installation branch outward Ear is equipped with sunpender on every group of installation trunnion.
The remarkable result of the utility model is: structure is simple, easy to operate, can be rushed to by successively deburring using the mold The left and right part of stringer lower plate behind hole carries out the secondary trimming and piercing die of one, compared to traditional technology, had both saved mold investment and had indulged The raw material that beam production expends, and prevent because the partially long buckling deformation that is distorted of part, also saves process, improves production Quality and production efficiency.

Specific embodiment
Specific embodiment of the present utility model and working principle are described in further detail with reference to the accompanying drawing.
As shown in Fig. 1~Fig. 6, a kind of secondary trimming-punching die of automobile longitudinal girder lower plate, including be oppositely arranged and mutual The part of the upper die and part of the lower die matched, wherein the part of the upper die includes upper die holder 1, the two sides of the upper die holder 1 pass through connecting rod 2 It is connected with the material pressing core 3 being arranged towards part of the lower die, is provided with multiple elasticity between the material pressing core 3 and the upper die holder 1 Material returned part 4 is also equipped with multiple edge-trimming cutters 5 in the bottom of the upper die holder 1 in 3 outside of material pressing core, and multiple edge-trimming cutters 5 are distributed In the left end of the material pressing core 3 and the two sides at middle part, opened up on the material pressing core 3 there are six formed punch via hole 6, in the leftmost side Several punching heads are provided in two formed punch via holes 6, the formed punch via hole 6 on secondary right side and two formed punch via holes 6 of the rightmost side 7, it is also installed with a formed punch 8 respectively in the formed punch via hole 6 on secondary left side and time right side, it is generally rectangular shaped compared with the formed punch 8 in left side, And its narrower part substantially trapezoidal compared with the formed punch 8 on right side is arranged towards left side;
The part of the lower die includes lower die holder 9, and the punch-pin 10 towards part of the upper die, the punch-pin are provided on the lower die holder 9 10 are adapted with the left and right stringer lower plate product after stretch forming, and at least two positioning pins 11 are fixed on the punch-pin 10.
At least two first correcting sliding blocks 12 are respectively and fixedly provided on the side wall of the side of the material pressing core 3;In the binder The front side wall of core 3 and rear wall are additionally provided with limited block 13, and the limited block 13 is to limit the relatively sliding of material pressing core 3 and upper die holder 1 Dynamic distance.
